Multigang filter used for laboratory

Abstract

The invention relates to a multigang filter used for a laboratory. The multigang filter comprises a stainless steel filtering bracket, a filtering cup, a filtering head, a dust-proof cup cover, a sintering filtering net and a filter membrane, wherein the filtering head is installed on the stainless steel filtering bracket and is provided with the filtering cup; the filtering cup is provided with the dust-proof cup cover; the filter membrane is pressed between the filtering cup and the filtering head; the sintering filtering net is installed on the boss of the filtering head on the lower part of the filter membrane. The multigang filter is characterized by also comprising an iron embedding part and a magnet embedding part, wherein one circle of iron embedding part is embedded in the outer wall of the lower end of the filtering cup; one circle of magnet embedding part is embedded into a position which corresponds to the iron embedding part on the outer wall of the upper end of the filtering head; the filtering cup and the filtering head are fixedly connected through the adsorption of the iron embedding part and the magnet embedding part. The multigang filter has the advantages of reasonable and scientific design and convenience in assembling, assembling efficiency is improved, the labor intensity of experimenters is lowered, and experiment efficiency and experiment data accuracycan be improved.

Description

technical field [0001] The invention belongs to the field of filtering equipment, and relates to a multi-connected filter, in particular to a multi-connected filter for a laboratory. Background technique [0002] Multi-filter is a common device used for solution filtration in laboratories. Its biggest feature is its high efficiency, which can realize multi-category filtration at the same time, thereby speeding up the process and bringing great convenience to enterprises. [0003] The existing multi-connected filter is composed of stainless steel filter bracket, filter cup, filter head, dust-proof cup cover, sintered filter screen, filter membrane and aluminum alloy clip, in which the aluminum alloy clip aligns the filter cup set up and down with the filter head The rear clip is fixed. This clamping method has high requirements on the assembly technology of the operator. The operator needs to grasp the clamping point of the clamp well, otherwise the liquid will leak from the...

AI Technical Summary

Problems solved by technology

This clamping method has high requirements for the operator's assembly technology. The operator needs to grasp the clamping force point of the clamp, otherwise the liquid will leak from the gap between the filter cup and the filter head due to uneven force. It will affect the scientificity and accuracy of the experimental data. If the filtered solution is a certain corrosive solution, it will also cause harm to the body of laboratory personnel and national property.

If it is a six-filter operation, it is more labor-intensive and complicated, because in each use process, according to the properties and components of the solution, it is necessary to replace the filter membrane frequently, clean the filter screen and the filter cup, and it will be repeated. Remove the clip to do these tasks, such repeated work is the most tedious and headache thing for the experimenters
