前 言离心机的发展有着悠久的历史，早在19世纪30年代在德国便问世了第一台离心机。在随后的时间里，离心机的技术发展获得了很大的进步，结构越来越紧凑，体积越来越小，分离效率不但提高等优点，使其在生产过程中得到广泛应用。离心机可以得到含湿量较低的固相和高纯度的液相，节省大量劳动时间和精力,减轻劳动强度，改善工作条件，提高工作效率，还具有连续运转，自动遥控，操作可靠安全，占地面积小等优点，很受欢迎。它的工作原理是以用转鼓旋转产生离心惯力，实现悬浊液，乳浊液及其它固液混合物料的分离或浓缩。 自动翻到卸料离心机是在三足式离心机的基础上，经过改良设计而成的。它保留了三足式离心机对物料适应性强，分离精度高，运转平稳，做简单等优点。而新增了对翻到架的设计，采用机械反倒卸料的方式，简化了操作过程，降低了劳动强度，提高了工作效率，同时液避免了刮刀卸料会破坏滤网和破坏物料晶粒的缺点。广泛的应用于松散晶体物料的分离脱水及化工，轻工，食品等行业。 摘 要该毕业设计题目是600液压翻倒离心机的设计。在张建伟老师和孟辉波老师悉心指导下，我进行了转鼓壁的厚度计算，拦液板的计算，转鼓底的设计，功率计算和电动机的选择，传动皮带的设计及选择，主轴的设计和强度校核，轴承的选择，翻到架的设计和强度计算，刹车的结构设计和强度计算，翻倒传动部分的设计计算，和其它的一些设计计算。在设计中，我首先要了解到离心机的工作原理：先由控制电路接通带动转鼓转动的电动机，通过皮带的传动使转鼓转动，转鼓转动使物料固液分离，液体通过离心机底部的排液管流出，固体留在转鼓壁上，然后再由控制电路接通翻倒电动机使离心机翻转倒出固体，这样就完成了分离的整个过程，这也是我们设计必须明白的。然后使了解离心机的各个零部件的构造和它们的材料工艺要求。最后对离心机进行整体的评定。关键词： 离心机；转鼓壁；转鼓底；刹车； AbstractThe graduation project entitled 600 hydraulic overturned centrifuge design.

clot portions, so that the serum may be quickly and readily removed without contamination by the clot portion. In recent years, biomedical and hospital laboratories have been faced with increasing demands for more and more routine, as well as specialized, diagnostic tests of blood samples. To meet the demands of these tests equipment has been devised which automatically takes a sample or specimen of blood which has been placed in a cup and subjects it to a series of programmed tests which eventuate in a readout on a record member. While these analyzers have increased the efficiency of performing the necessary tests, a problem has continued in finding ways and means of separating the serum from the clot portion and removing the serum for analysis. Various types of tube and plug devices have been suggested by the prior art. For example, in U.S. Pat. No. 3,512,940, issued May 19, 1970, a device consisting of a tube with a filter at one end thereof is inserted into a second but larger diameter tube containing a sample of the material desired to be filtered. In U.S. Pat. No. 3,508,653, issued Apr. 28, 1970, a piston in the form of a solid plug is driven through a centrifuged blood sample so as to position itself between the serum and clot portions of the centrifuged sample. The tube within the tube concept of U.S. Pat. No. 3,512,940 suffers from the apparent deficiency of being costly and not readily adaptable for disposal after a single use. The plug arrangement of U.S. Pat. No. 3,508,653 has the shortcoming of utilizing a solid plug member which when subjected to a substantial centrifugal force, may also develop radial forces acting against the side of the sample tube, thus creating the danger of breakage. SUMMARY OF THE INVENTION The present invention provides a method by which the serum and clot portions of the blood sample are separated quickly and effectively by use of a simple device containing a liquid sealant consisting essentially of a silicone fluid and silica. The sealant has a specific gravity of at least 1.026 and preferably in the range of 1.030 to 1.050. As such, it will normally be at the proper specific gravity to divide the serum and clot portions of the centrifuged sample, sealing the clot in the container while the serum is removed. Accordingly, it is an object of the present invention to provide a simple and effective method of obtaining a serum sample during centrifuging. DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded partially sectional view of a sample tube and dispenser to carry out the process of the present invention; FIG. 2 is a partially sectional side view of a sample tube and dispenser to carry out the process of the present invention with the dispenser inserted into a supply of blood; FIG. 3 is a partially sectional view similar to that of FIG. 2 wherein the blood, sample tube and dispenser have been partially subjected to centrifuging; FIG. 4 is a view similar to FIG. 2 wherein the blood, the sample tube and dispenser have been subjected to the complete centrifuging step; FIG. 5 is a sectional view of the sample tube with the separator in place overlying the clot portion with the serum portion removed; FIG. 6 is an enlarged sectional view of the sealant dispenser showing the sealant contained therein; FIG. 7 is a top view of the dispenser of FIG. 6; and FIG. 8 is a bottom view of the dispenser of FIG. 6. DESCRIPTION OF THE ILLUSTRATED EMBODIMENT Referring to the drawings, a container 10 for holding a blood sample is illustrated as a straight side wall sample tube 10 with an open top end 11. Into the open top 11 is inserted a dispenser 12. The dispenser 12 has a flange member 14 which overlies the top edge 16 of the side wall 18 of the container. The dispenser 12 includes a body portion 19 consisting of three ring sections 20, 22 and 24. Extending from the body 19 is an elongated nozzle portion 26 and at the end of the nozzle 26 is a tip 28 having an opening 30 therein. The purpose of the three rings 20, 22 and 24 is to permit the dispenser 12 to be used with containers of various diameters. Ring 20 has a shoulder 32 and a side wall 33, ring 22 a shoulder 34 and a side wall 35, and ring 24 has a shoulder 36 and a side wall 37. When using a narrow container, the dispenser bears on the top edge of the side wall of the container at one of the shoulders 32, 34 or 36 and the side wall of the next smaller ring is parallel with the inner side wall of the container. During centrifuging the relationship between the inner surface of the container and the side wall of the ring insures stability of the dispenser during this period. By utilizing a dispenser as illustrated herein, it is possible to use one dispenser for varying diameter containers. The body portion 19 of the dispenser has an open end 37 over which is placed a seal 38. The seal 38 has a small opening 40 therein. The seal 38 is not placed over the open end until a sealant 42 has been placed in the dispenser. The sealant 42 consists essentially of a silicone fluid with an inert filler, such as silica, dispersed therein. The sealant should have a specific gravity of at least 1.026 and preferably in the range of 1.030 to 1.050. The normal specific gravity of blood as determined by the pycnometric method is considered to be in the range of 1.048 to 1.066 with averages of 1.052 to 1.063. After centrifuging the specific gravity of the blood serum which separates from the remainder of the blood is at least 1.026 and in the range of 1.026 to 1.031. The specific gravity of the heavier portions such as the erythrocytes is 1.092 to 1.095. In selecting a sealant it is necessary to select one which has a specific gravity greater than that of the serum portion. Accordingly, the sealant should have a specific gravity of at least 1.026. However, its specific gravity should not be too high so as to cause it to layer somewhere in the clot portion. Such layering would be of no practical use towards obtaining a separated serum portion. A preferred sealant would have a specific gravity in the range of 1.030 to 1.050. The sealant is also preferably thioxtropic, water insoluble, substantially non-toxic as well as substantially chemically inert with respect to the constituents of the blood sample, particularly those in the serum portion. A preferred sealant formulation is as follows: EXAMPLE I Parts by weight Silicone fluid (dimethylpolysiloxane) 100 Silica (specific gravity 2.65) 8 Silica (specific gravity 2.3) 6 The silicone fluid used in Example I was a dimethyl-polysiloxane polymer made by Union Carbide Corporation and identified by the designation L-45. It had a viscosity of 12,500 centistokes and a specific gravity of about 0.973 at 25.degree.C. The silica with a specific gravity of 2.65 was an amorphous silica having a particle size of at least 75 percent being less than 5.0 microns. It was made by Whittaker, Clark & Daniels and identified by the designation No. 31 Lo Micron. The silica with a specific gravity of 2.3 was a hydrophobic amorphous silica having an average particle size of about 20 millimicrons. It was made by Degussa Inc. and identified by the designation Aerosil R 972. The silicone fluid and the silica were mixed together to a thixotropic condition with a resultant specific gravity of 1.045 to 1.050 to form the sealant. The sealant was then placed in a dispenser of the type illustrated in FIG. 6 in particular. The diameter of the flange was 0.70 inches and the overall length 1.75 inches with the nozzle and tip being 1.10 inches. The opening in the tip was 0.032 inches. The filled dispenser was placed in a standard sample tube having an overall length of 3.875 inches with the shoulder 32 of the first ring resting on the top of the tube side wall. The tube had previously been filled with a whole blood specimen to within 1.10 inches of the open end of the tube. The extent of the dispenser from shoulder 32 to the end of the tip was 1.5 inches. Thus, the dispenser tip and part of the nozzle extended well into the blood sample. The tube with the blood sample and dispenser was centrifuged for approximately 10 minutes. After 5 minutes substantially all of the sealant had passed from the dispenser. The sealant did not disperse but instead remained homogeneous and settled as a layer between the serum and clot portions of the centrifuged blood. It was noted that the sealant settled as a substantially even layer between the two portions since its specific gravity of 1.045 to 1.050 was less than that of the clot portion and greater than that of the serum portion. The sealant formed a tight seal against the inner wall of the tube. Also noted was the fact that the sealant had mixed into it, particularly in the portion near the clot portion, fibrant matter which had been filtered out of the serum portion as the sealant settled to its own specific gravity level. The use of the dispenser which extended into the blood sample expedited the procedure since it was not necessary for the sealant to overcome the surface tension of the blood sample. With the sealant in place it was possible to merely decant off the serum portion with the clot being trapped behind the sealant. The specific gravity of the sealant was determined by using a copper sulfate method. The procedure consists of letting drops of the sealant fall into a graded series of solutions of copper sulfate of known specific gravity and noting whether the drops rise or fall. The series used were graded at 0.005 intervals. Merely by observing the drops it was possible to determine that the sealant had a specific gravity between 1.045 and 1.050. Another sealant formulation is as follows: EXAMPLE II Parts by weight Silicone fluid (dimethylpolysiloxane) 100 Silica (specific gravity 1.95) 14 The silicone fluid of Example II is the same dimethylpolysiloxane polymer of Example I. The silica with a specific gravity of 1.05 has an average particle size of 16 millimicrons. It is made by Henlig & Co. and identified by the designation TRI-SIL 404. The specific gravity is from 1.045 to 1.050. Still another sealant formulation is as follows: EXAMPLE III Parts by weight Silicone fluid (ethyltriethoxysilane) 100 Silica (specific gravity 2.65) 8 Silica (specific gravity 2.3) 20 The silicone fluid of Example II is an ethyl-triethoxysilane monomer made by Union Carbide Corporation and identified by the designation A-15. The silicas are the same as those used in Example I. The filler serves the dual purpose of making the silicone fluid thixotropic and of adjusting the specific gravity to that which is desired for the resultant sealant. In place of silica other inert fillers which may be used in a fine powdered form are bentoniate, alumina and talc. Others will also occur to those skilled in the art. Another silicone fluid which may be used is made by Dow Corning Corporation and identified as 200 Fluid. In selecting silicone fluids and fillers, one should select materials which when mixed together will give the desired specific gravity, be substantially non-toxic, water insoluble and substantially chemically inert with respect to the constituents of at least the serum portion. The dispenser serves to meter out the sealant gradually and this gradual metering provides sufficient lead time for the centrifugation to take effect before the sealant is in place. If the sealant were allowed to be positioned too soon some unwanted matter, such as red cells or fibrilar like material, may be trapped in the serum portion by the sealant. While various examples have been described herein and one embodiment illustrated on the drawings, those skilled in the art may practice the invention in its various forms by other examples and embodiments without departing from the scope of the claims herein. 血清分离方法本发明涉及到一种方法，仪器和合成物分离采集血样离心成血块部分，从而使血清可迅速和容易地删除而不会受到污染的凝结部分。 近年来，生物医学和医院实验室已经面临着日益增加的需求对于越来越多的例子，以及专门的诊断测试的血液样本。为满足这些试验设备已制定的自动样品或标本的血液已放置在世界杯和科目它进行了一系列试验，计划在读归结于创纪录的会员。虽然这些分析仪增加了效率，履行了必要的试验，这个问题一直在寻求各种方式和途径分离血清和消除血凝块部分血清进行分析。各类管和插件设备已经提出的先有技术。例如，在美国帕特。 3512940号，印发1970年5月19号，装置组成的管过滤器在一端有插入第二，但大直径管的样本含有的物质理想的筛选。美国的帕特。 3508653号， 4月28日发出， 1970年，活塞的形式，扎实推动插件通过离心血液样本，以自己的位置之间的血清和血凝块部分离心样品。该管的管内概念的美国帕特。第3512940的明显的不足是昂贵，而不是容易适应的处置后，一次性使用。插件安排美国帕特。编号3508653的缺点是使用了坚硬材料时，受到很大的离心力，也可能发展径向力对一侧的样品管，从而造成断裂的危险。概要发明 本发明所提供的方法是血清和血凝块部分血液样本分离迅速和有效地利用一个简单的装置含有液体密封胶的组成基本上硅油和硅。密封剂的比重至少在1.026和最好的范围1.030到1.050 。因此，它通常会在适当的比重分裂血清和血凝块部分离心样品，密封的容器中的血块，而血清中删除。 因此，它是一个对象本发明提供一种简单而有效的方法获得血清样本在离心。描述图样 1是一个爆炸部分断面鉴于样品管和饮水机进行的过程中本发明;体操。二是部分断面侧视图一个样品管和饮水机进行的过程中与本发明的饮水机插入血液供应;体操。三是部分截面类似无花果。 2 ，其中血液，样品管已部分受到离心;国际联合会。 4期类似体操。 2 ，其中血液，样品管和离心机受到完整的离心步骤;体操。 5是一个截面的样品管与分离器在部分覆血栓与血清部分拆除;体操。6是扩大截面的密封胶密封胶机显示所载;体操。 7是最鉴于离心中心。附带说明描述 在谈到图样，一个集装箱10举行的血液样本显示了作为一个连续侧墙样品管与一个开放的10高端11 。公开前11插入配药12 。喷雾器12法兰会员14 overlies顶部边缘16侧墙18集装箱。喷雾器12个，包括19个机构组成部分的三个环第20 ，第22和第24 。从19日的身体是一个细长的喷嘴部分26和结束时的喷嘴26日是一个提示28日开幕30日在那里。的目的，这三个20环， 22日和24日是允许机12可用于各种容器的直径。环20肩膀32和33侧墙，戒指22肩膀34和侧墙35 ，和24环的肩膀36和侧墙37 。当使用一个狭窄的容器中，饮水机熊的顶部边缘的侧壁上的集装箱之一的肩上32 ， 34或36和侧墙下一小环与内侧壁的容器。在离心之间的关系，内表面的容器和侧壁的环保证稳定的饮水机，在此期间。 通过利用此机可以看出，可以用一个饮水机不同直径容器。正文部分19饮水机已
