Technical background:
In hydrometallurgy, chemical industry, food service industry, the feeding manner of liquid-solid separation filter half-moon groove has two kinds, i.e. an endfeed and two endfeeds.Said herein two endfeeds, an in fact still endfeed enters because the charging house steward is a end from filter, promptly is introduced into an end of filter half-moon groove by the slip of sending here outside the battery limit (BL), extends the half-moon groove that enters the other end more then.
There is the problem of solids distribution inequality in the half-moon groove in above-mentioned two kinds of feeding manners, make feed end contain height admittedly, and the other end contains low admittedly, cause therefrom and filter the production capacity reduction, and filter cake contains the high adverse consequences of liquid (water) rate.
The utility model content:
The purpose of this utility model is: a kind of new two ends feed arrangement is provided, the material in the filter half-moon groove is evenly distributed, to improve filter efficiency, reach the effect that improves the filter production capacity and reduce filter cake moisture (liquid) rate.
The utility model is to constitute like this: it comprises separator (5), half-moon groove (6), charging house steward (1) is connected with valve (9) with valve (2), valve (2) is in charge of (3) and is connected with charging, charging is in charge of (3) and is connected with charging aperture (4), and valve (9) is in charge of (8) and is connected with charging, and charging is in charge of (8) and is connected with charging aperture (7), charging aperture (4) and charging aperture (7) are at the two ends of half-moon groove (6), and the following outlet of half-moon groove (6) is connected with separator (5).
During work, feed liquid is after charging house steward (1) process valve (2) and valve (9) distribution, (3) are in charge of in the charging that enters two ends simultaneously and (8) are in charge of in charging, be in charge of charging aperture (4) and the charging aperture (7) that enters half-moon groove (6) two ends respectively from these two chargings, enter half-moon groove (6) by these two charging apertures, in half-moon groove (6), enter separator (5) after uniform.
The beneficial effects of the utility model are, and are simple in structure, easy to operate, can guarantee the even charging in two ends, realize that material is uniform in the filter half-moon groove, improve filter efficiency, reach the effect that improves the filter production capacity and reduce filter cake moisture (liquid) rate.
