Description

Technical Field

[0001] This utility model relates to the field of biological reagent testing technology, and more specifically, to a biological reagent testing dissolution and filtration device. Background Technology

[0002] In biological reagent testing, dissolution filtration refers to the process of dissolving samples and filtering them using a filter membrane with a specific pore size during biochemical experiments or quality control to separate microorganisms, particles, or other impurities, ensuring the clarity and purity of the solution. Biological reagents require filtration during preparation to guarantee their purity.

[0003] Existing filtration devices typically filter biological reagents through a filter screen. However, the reagents may condense during filtration, and the condensed lumps can easily clog the filter screen's pores, preventing the liquid from passing through smoothly and thus reducing filtration efficiency and resulting in poor performance. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a biological reagent testing dissolution and filtration device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biological reagent testing dissolution and filtration device, comprising a vertical cylinder and a storage cylinder, wherein the storage cylinder is threadedly connected to the outer bottom edge of the vertical cylinder, a filter screen plate is movably arranged inside the vertical cylinder, and a rotating assembly is arranged on the top of the filter screen plate, the rotating assembly comprising a hydraulic cylinder, a mounting plate, a motor, a rotating shaft, three stirring rods and a brush plate, the bottom end of the hydraulic cylinder being fixedly connected to the mounting plate, and the motor being fixedly mounted on the bottom end of the mounting plate, the top and bottom ends of the rotating shaft being fixedly connected to the output shaft end of the motor and the brush plate respectively, and the three stirring rods being fixedly sleeved on the rotating shaft.

[0006] Furthermore, a fixed cylinder is fixedly connected to the center of the top of the vertical cylinder, and the bottom of the inner part of the fixed cylinder is fixedly connected to the hydraulic cylinder.

[0007] It can be seen that the above technical solution is designed to facilitate the support and fixation of the hydraulic cylinder.

[0008] Furthermore, a feed hopper is fixedly connected to the top of the vertical cylinder near one side edge, and a valve is fixedly installed on the feed hopper.

[0009] As can be seen, in the above technical solution, the valve is opened and the biological reagent and diluent are poured into the feed hopper, and the biological reagent and diluent enter the vertical cylinder through the feed hopper.

[0010] Furthermore, a protective sleeve is movably provided on the outside of the motor, and the top of the protective sleeve is fixedly connected to the vertical cylinder.

[0011] As can be seen, the above technical solution aims to prevent biological reagents and diluents from directly contacting the motor.

[0012] Furthermore, the bottom end of the filter plate is fixedly connected to two clamping rods, and the top ends of both clamping rods extend into the storage cylinder.

[0013] It can be seen that the above technical solution aims to improve the stability between the storage cylinder and the filter screen.

[0014] Furthermore, a limiting ring is movably provided on the top of the filter plate, and the limiting ring is fixedly installed inside the vertical cylinder, with a sealing gasket adhered to the bottom end of the limiting ring.

[0015] As can be seen, in the above technical solution, the limiting ring can limit the position of the filter screen plate, and the sealing gasket can improve the sealing between the filter screen plate and the limiting ring, effectively preventing solution leakage.

[0016] Furthermore, a liquid outlet is provided at the center of the bottom end of the storage cylinder.

[0017] It can be seen that the above technical solution is designed to facilitate the discharge of the solution.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. This utility model uses a motor to drive three stirring rods to rotate, which stir the biological reagent and diluent. The filter screen filters the mixture, and the clumps remain on the top of the filter screen. At the same time, the rotating shaft can drive the brush plate to rotate, and the bristles on the brush plate clean the clumps adhering to the filter screen. The operation is simple and convenient for cleaning the clumps adhering to the filter screen, which effectively improves the filtration efficiency and has a good effect.

[0020] 2. This utility model allows the solution in the storage cylinder to be discharged through the outlet by rotating the piston away from the outlet. Rotating the storage cylinder away from the vertical cylinder allows the filter screen to be removed from the storage cylinder and cleaned and replaced. At the same time, the lumps adhering to the inner wall of the vertical cylinder are cleaned. Similarly, the filter screen is installed. The two clamps can improve the stability between the storage cylinder and the filter screen. The structure is simple and easy to use. Attached Figure Description
