Filter press used for pymetrozine production and having high-efficiency sealing structure

Abstract

The invention discloses a filter press used for pymetrozine production and having a high-efficiency sealing structure, wherein the filter press comprises a main body, an inner liner and a filter plate. The top end of the main body is clamped and connected with a top cover, and the transverse section size of the top cover is larger than the transverse section size of the top end of the main body; the upper surface of the main body is fixedly provided with a shell, and an inner cavity of the shell is inserted with a piston, and the outer end of the piston is closely fitted with the inner wall ofthe shell; the surface of the left end of the top of the main body is welded with a protrusive plate; the inner liner is located inside the main body; the filter plate is mounted at the bottom end ofthe inner liner; the left end of the cavity is provided with a solid block; the surface of the right end of a collection box is welded with a pull rod. According to the filter press used for pymetrozine production and having the high-efficiency sealing structure, the top end of the filter press can be tightly sealed through the top cover and the sponge pad on a lower surface of the top cover, andexternal gas cannot be permeated when materials are collected. At the same time, the inner part of the filter press is protected by an internal elastic structure when collision occurs.

Description

technical field [0001] The invention relates to the technical field of pymetrozine production, in particular to a filter press for pymetrozine production with an efficient sealing structure. Background technique [0002] The filter press is a small device for liquid filtration through pressure. Specifically, the internal liquid is discharged through the filter screen by pumping air into the device, and at the same time, the particles are filtered out. Due to the small size and simple structure of the filter press, The operation is simple and uncomplicated, and its cost is low, so it is widely used in the production of pymetrozine; [0003] However, there are also some problems in the existing filter presses on the market, such as; [0004] 1. The seal is not tight enough, causing the gas to leak out when inflating, so that the internal air pressure cannot meet the pressure filtration standard, and the liquid cannot be filtered; [0005] 2. The structural strength of the fi...
