Combined corner feeding chamber-type filter plate and liquid discharge method thereof

Abstract

A combined corner feeding chamber-type filter plate and a liquid discharge method thereof are provided. A main plate and an auxiliary plate are set into an assembly; two sides of the main plate are provided with outer lugs, each outer lug is provided with a corner feeding passage, a feeding hole connected with the corner feeding passage, a distribution hole connected with the feeding hole and filter chambers on two sides of the combined filter plate, a hidden flow hole and a liquid outlet connected with the hidden flow hole, a rubber seal ring is disposed at each corner feeding passage and the corresponding hidden flow hole, the auxiliary plate matches with the main plate in appearance and size, and drain holes are arranged in each filter chamber; the liquid discharge method is characterized in that the liquid outlets are connected to the drain holes in the lower corners of the filter chambers at the lower ends of the corner feeding passages of the main plate in order to discharge filtrate through the hidden flow holes, the liquid outlets are connected to the right lower corners of the lower ends of the filter chambers of the filter plate in order to discharge filtrate through the hidden flow holes, each filter plate assembly needs to be symmetrically mounted according to the lower liquid outlets for discharging, filter drain structure is of pressure fusion form, and discharging is of symmetric distributary form.

Description

technical field [0001] The invention belongs to the field of filter presses of filtering equipment, and in more detail, relates to a combined angle-feeding box-type filter plate and a liquid outlet method. Background technique [0002] The box-type filter plate is the main filter element of the filter press. It is very important to select the feed and discharge form of the box-type filter plate for material filtration. At present, the material is generally filtered through the center feed hole of the box-type filter plate to enter the filter chamber. , the filter cake is formed by the particles in the material intercepted by the filter cloth in the filter chamber, and the filtrate is discharged from the four corner liquid outlet holes to achieve the purpose of solid-liquid separation. [0003] Due to the development of the economy, the types of materials filtered by the solid-liquid separation industry are gradually increasing, and the water content of the filter cake requir...

AI Technical Summary

Problems solved by technology

[0003] Due to the development of the economy, the types of materials filtered by the solid-liquid separation industry are gradually increasing, and the water content of the filter cake required by material filtration is getting lower and lower. Some chemical industries wash the filter cake to improve the purity of the filter cake, or through washing Using filter cake to increase the recovery rate of filtrate, reducing costs and improving filtration efficiency are common requirements of users. Therefore, some materials in the box-type filter plates currently used are not suitable for filtration. The filter cake has high moisture content and slow filtration speed. To the material filtration effect, can not meet the user's filtration requirements
