A filter feeding device and method for sponge cadmium

Abstract

The invention discloses a sponge cadmium filtering and feeding device and method. The device comprises a silo (1) with upper and lower openings, a silo liquid accumulation plate (2) surrounding the bottom of the entire silo, and a silo connected to the outlet at the lower end of the silo. The feeding pipe (4) and the waste liquid tray (5) placed under the compactor (9) and surrounding the entire compactor (9); the bottom side wall of the silo (1) is provided with a waste liquid supply A plurality of filter holes (8) flowing out; a valve (3) is provided between the silo (1) and the silo lower pipe (4); ) is connected to the waste liquid tray (5), and the bottom of the waste liquid tray (5) is provided with a liquid outlet pipe b (7) for the waste liquid to flow out. The feeding method using this device overcomes the time-consuming and labor-intensive drawbacks of traditional sponge cadmium filtration and delivery to the briquetting machine, and has the advantages of high efficiency, easy 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
