Filtering and pushing mechanism of extraction and filtration groove for product

Abstract

The invention discloses a filtering and pushing mechanism of an extraction and filtration groove for a product. The filtering and pushing mechanism comprises a bracket and a groove body, wherein two discharging openings are formed in the bottom of the groove body; a plurality of end-surface vertical-rib plates are arranged at the two sides of an end surface plate; a filtering-sieve supporting plate is fixedly arranged on a side-surface plate; a filtering sieve plate is supported on the filtering-sieve supporting plate, and is also supported on the end-surface vertical-rib plates by a supporting frame; an arc-shaped sieve net installing groove is formed between the two end-surface vertical-rib plates close to the lower end of the bottom plate and is internally provided with an arc-shaped sieve plate; a plurality of inclined-surface rib plates are fixedly arranged on the bottom plate; the two opposite inclined-surface rib plates are fixedly connected by a connecting plate; and a cylinder pushing mechanism is also fixedly arranged on the outer wall of the side surface. The filtering and pushing mechanism disclosed by the invention has the obvious effects that enough support can be provided for the filtering sieve plate; the structure is relatively stable; convenience is brought for cleaning the bottom of the extraction and filtration groove; and the pushing is carried out by a cylinder, so that rapid filtering can be achieved.

Description

technical field [0001] The invention relates to the technical field of chemical filter equipment, in particular to a filter pushing mechanism for a product suction filter tank. Background technique [0002] Suction filters are common devices in chemical plants and chemical laboratories. According to the needs of the operator, it can choose different materials and filter membranes with different filter pore sizes to achieve the functions of removing impurities in the solvent, purifying and sterilizing bacteria. In chromatographic analysis, the solvent filtered by it can not only effectively extend the service life of the chromatographic column, but also can significantly improve the data accuracy of the analysis system due to its vacuum degassing effect. [0003] However, in the prior art, only the two ends of the filter screen are supported, which often cannot provide enough support for the filter screen, so that the service life of the filter screen is reduced; the paralle...

AI Technical Summary

Problems solved by technology

[0003] However, in the prior art, only the two ends of the filter screen are supported, which often cannot provide enough support for the filter screen, so that the service life of the filter screen is reduced; the parallel setting of the filter screen membrane will reduce the filtration rate, and for some The solvent exposed to the air for a long time will affect the chemical properties of the solvent; there is no space to gather solid substances, which is not convenient for the centralized treatment of solid substances; in addition, the filter screens are fixed in the suction filter, which is inconvenient to clean after use
