Description

Multilayer filtering centrifugal column

Technical Field

The utility model relates to a centrifugation post field, concretely relates to multilayer filters centrifugation post.

Background

The centrifugal column is an experimental consumable for adding various chromatographic fillers into the column and obtaining target protein by utilizing the characteristics of the fillers. Although current chromatography pre-installation post is a can use experimental consumptive material product many times repeatedly, at the in-process that uses, generally need filter the impurity in the filler in order to obtain high-purity filler, in order to solve this problem, often need set up a plurality of sieve boards in the column tube and filter, the sieve of traditional type adopts integrated structure design with the column tube usually, consequently, is more troublesome at the in-process of wasing the sieve, for this reason, urgently need solve current problem.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, an object of the utility model is to provide a multi-layer filter centrifugal column, reach the purpose that can dismantle the multilayer sieve.

In order to achieve the purpose, the multi-layer filtering centrifugal column comprises an upper end cover, a lower end cover, a column tube and a plurality of sieve plates, wherein the upper end cover is detachably connected to the top of the column tube, and the lower end cover is detachably connected to the bottom of the column tube;

the inner surface of the column tube is designed in a conical shape, the sieve plate is designed in a conical shape, the conical degree of the sieve plate is equal to that of the inner surface of the column tube, the bottom surfaces of the sieve plates are different in size, and a plurality of sieve plate holes are formed in the sieve plate.

Furthermore, the sieve plate holes are arranged on the sieve plate in a circumferential array mode.

Further, the upper end cover is connected to the upper portion of the column tube in a threaded mode.

Furthermore, anti-skid threads are fixedly arranged on the outer surface of the column tube, the upper end cover and the lower end cover.

Further, the lower end cover is connected to the bottom of the column tube in a threaded mode.

Compared with the prior art, the utility model, its beneficial effect is:

when the filler is required to be added into the column tube, firstly, the lower end cover is screwed into the bottom of the column tube, then the sieve plate is sequentially placed into the column tube from small to large, and the edge of the sieve plate can seal the inner surface of the column tube due to the fact that the taper of the sieve plate is equal to the taper of the inner surface of the column tube, the filler is prevented from flowing away from a gap between the sieve plate and the column tube, and therefore the filtering effect cannot be achieved, and when the filler flows from top to bottom, the sieve plate can be stably fixed in the column tube, so that the multi-layer filtering effect is achieved, and finally, the upper end cover is screwed into the top of the column tube, and the filler can be charged;

when the sieve plate needs to be cleaned, the upper end cover and the lower end cover are respectively screwed off, then clear water is filled from the bottom of the column tube, and the sieve plate is pressed out of the column tube under the action of water pressure, so that the function of separating the sieve plate is achieved;

in conclusion, the multilayer filtering centrifugal column is adopted to achieve the purpose of disassembling the multilayer sieve plate.
