Stable film filtering device

Abstract

The invention discloses a stable film filtering device. The device comprises a filter hopper assembly, a liquid storage filter barrel, a connecting pipeline, a vacuumizing pump assembly and a stable support. A through hole is formed in the stable support, a stable supporting table area is arranged in the middle of the stabile support, the filtering hopper assembly is stably installed on the stablesupport, the liquid storage filtering barrel is connected with the liquid storage filtering barrel through the connecting pipeline, the vacuumizing pump assembly is installed on the liquid storage filtering barrel, and the liquid storage filtering barrel and the vacuumizing pump assembly are integrally installed on the stable supporting table area in the middle of the stabile support. The deviceis good in overall stability, the filter membrane is convenient and stable to assemble and disassemble, the overall height of the stabilizing frame can be adjusted according to actual needs, the problems that a filter cone assembly is poor in stability and inconvenient to disassemble, and the filter membrane is prone to tilting or wrinkling during filtration are solved, and the filter cone assembly is suitable for popularization and application during mixed liquid filtration and filtration and separation of microorganisms in liquid in laboratories.

Description

technical field [0001] The invention relates to the field of stable membrane filtration devices, in particular to a stable membrane filtration device. Background technique [0002] In the process of environmental testing, chemical engineering and related industrial experiment research, it is often necessary to filter sediments and filter microorganisms for solid-liquid mixtures or liquid mixtures. In the above-mentioned filtration separation process, it is usually necessary to perform membrane or filter paper filtration separation on these mixtures. But common film or filter paper filter separation device has the following problems in actual use: 1, the overall design of common filter separation device is unreasonable, and in the process of filtering, film or filter paper often warps and wrinkles, making the waiting time The filtered and separated mixed liquid flows into the filtered liquid from the warping and wrinkling of the film or filter paper, resulting in incomplete ...

AI Technical Summary

Problems solved by technology

At the same time, the invention has good overall stability, convenient and stable loading and unloading of the filter membrane, and the overall height of the stable frame can be adjusted according to actual needs, which solves the problems of poor stability of the filter bucket assembly, inconvenient disassembly, and easy warping or wrinkling of the filter membrane during filtration , eliminating the phenomenon of overflow due to overfilling of the liquid storage tank
