Sponge cadmium filtering and feeding device and sponge cadmium filtering and feeding method

Abstract

The invention discloses a sponge cadmium filtering and feeding device and a sponge cadmium filtering and feeding method. The device comprises a material bin (1), a material bin liquid collecting disc (2), a material bin blanking pipe (4) as well as a waste liquid tray (5), wherein the top and the bottom of the material bin (1) are opened; the material bin liquid collecting disc (2) surrounds the bottom of the whole material bin; the material bin blanking pipe (4) is communicated with an outlet at the lower end of the material bin; the waste liquid tray (5) is arranged below a briquetting machine (9) and surrounds the whole briquetting machine (9); the side wall at the bottom of the material bin (1) is provided with a plurality of filtering holes (8) through which waste liquid flows out; a valve (3) is arranged between the material bin (1) and the material bin blanking pipe (4); the material bin liquid collecting disc (2) is connected with the waste liquid tray (5) through a liquid discharge pipe a (6); and the bottom of the waste liquid tray (5) is provided with a liquid discharge pipe b (7) through which waste liquid flows out. The defect that the traditional briquetting machine wastes time and labor in delivering sponge cadmium is overcome by a feeding method of the device, and the device and the method have the advantages of high efficiency, easiness in automatic control, low labor intensity and less material loss.

Description

technical field [0001] The invention relates to the field of filtering and feeding devices, in particular to a device and a filtering and feeding method for separating material and liquid from sponge cadmium slurry obtained by replacing zinc powder, and adding the dehydrated sponge cadmium to a compactor. Background technique [0002] The sponge cadmium slurry obtained by zinc powder replacement needs to be filtered and dehydrated, and then pressed into a certain size of agglomerate, which is convenient for the next step. In the prior art: after the sponge cadmium slurry is filtered and dehydrated (by using a filter press, vacuum suction filter or natural filter), the sponge cadmium is manually shoveled into the compacting machine and pressed into pellets. As a result, the labor intensity is high, the material loss is large, the sponge cadmium is easily oxidized, and the appearance quality of the cadmium group is not good. [0003] Sponge cadmium slurry has a large water co...

AI Technical Summary

Problems solved by technology

[0004] Existing liquid-solid separation of sponge cadmium, the process of sending and pressing the ball is generally stacked, manually shoveled, and directly contacted with a large amount of air. Manual handling will break the cadmium ball, resulting in oxidation of the sponge cadmium and a decline in quality

At the same time, workers are in close contact with the sponge cadmium, resulting in potential poisoning
