Embodiment Construction
[0009] Embodiment of the present invention: the feed main pipe 1 of the filter is laid on the middle part of the half-moon tank 6 front of the filter, the feed main pipe 1 is connected with the valve 2 and the valve 9, and the feed branch pipe 3 and the feed branch pipe 8 are sequentially connected They are respectively connected to the feed port 4 and the feed port 7, and the half-moon tank 6 is connected to the separation device 5.
[0010] When working, the feed liquid is distributed from the feed main pipe through two valves, and then enters the feed branch pipes at both ends at the same time, enters the feed ports at both ends of the half-moon tank from the feed branch pipe, enters the half-moon tank from the feed port, and enters the half-moon tank. After uniform distribution, it enters the separation device.

The invention discloses a method of equispaced feeding for solid-liquid separation filter and the device. The feeding main pipe is lied in the center of semi-lunar tank face side, the feed liquid is distributed through two valves and enters into two feed pipes, then enters into feed inlet on two ends of semi-lunar tank, and enters into semi-lunar tank, finally enters into debonding unit after equipartition in semi-lunar tank. The invention is characterized by simple construction, convenient operation, even feed on two ends, increased filtering efficiency and reduced moisture percentage of filter cake. The invention can be used in hydrometallurgy, chemical industry and foodstuff industry.
Description
Technical field: [0001] The invention relates to a feeding method and a device for a liquid-solid separation filter. technical background: [0002] In the hydrometallurgy, chemical industry, and food industries, there are two feeding methods for the half-moon tank of the liquid-solid separation filter, namely, one-end feeding and two-end feeding. The feeding at both ends mentioned here is actually feeding at one end, because the main feed pipe enters from one end of the filter, that is, the slurry sent from outside the boundary area first enters one end of the half-moon tank of the filter, and then extends again. Enter the half-moon trough at the other end. [0003] The above-mentioned feeding method has the problem of uneven distribution of solids in the half-moon tank, so that the solid content at the feeding end is high and the solid content at the other end is low, resulting in reduced filtration capacity and high liquid (water) rate in the filter cake.
