Method and device for improving capacity of disc-type vacuum filter

Abstract

The invention relates to a method and device for improving the capacity of a disc-type vacuum filter. The device comprises a tank body (1), a feeding pipe (4), an overflow groove (5), a first overflow pipe (6), a second overflow pipe (7) and a third overflow pipe(8), wherein the rear end of the feeding pipe (4) is positioned above the liquid level of slurry (3); the middle of the feeding pipe (4)is bent downwards and penetrates into the bottom of the tank body (1); and the front end of the feeding pipe (4) is bent upwards. When the disc-type vacuum filter is used for dewatering, the amount of the slurry (3) input into the tank body (1) is increased, so that the liquid level of slurry (3) is higher than the overflow groove (5); the feeding pipe (4) penetrates into the bottom of the tank body (1); and the slurry (3) flows into the overflow groove (5) along with the movement of the disc-type vacuum filter, and is discharged out of the overflow pipe. According to the method and the device for improving the capacity of the disc-type vacuum filter, slurry concentration in the tank body is constant so as to guarantee dewatering efficiency and improve capacity.

Description

technical field [0001] The invention belongs to the field of solid material conveying and dehydration, and in particular relates to a method and a device for improving the productivity of a disc vacuum filter. Background technique [0002] The disc vacuum filter is widely used in the field of tailings dewatering, and has been widely promoted in the sludge, sediment and other environmental protection industries. The machine has the characteristics of convenient operation, continuous operation, simple process and good reliability. [0003] The disc vacuum filter can mechanically dehydrate tailings, cement raw slurry, sludge, sediment and other solutions, and filter and dehydrate the slurry with a water content of 35% to 40% into a filter cake with a water content of about 18%. [0004] figure 1 It is a schematic diagram of the dehydration structure of the existing disc-type vacuum filter. As shown in the figure, the original feed pipe 10 is located above the tank body 1 and ...

AI Technical Summary

Problems solved by technology

[0005] The present invention designs a method and device for improving the production capacity of a disc vacuum filter, which solves the problems of low slurry concentration at the upper part of the tank and high concentration at the bottom of the tank caused by the dehydration process of the disc vacuum filter. It also fluctuates accordingly, making its production capacity unstable and affecting the dehydration efficiency
