Further, the diameter of described many backwashing water pipelines is greater than the diameter of the junction pipeline of described many backwashing water pipelines and described device for filtering and collecting.
Further, the ratio of the junction pipeline of the diameter of described many backwashing water pipelines and described many backwashing water pipelines and described device for filtering and collecting is 2: 1.
Further, the bottom of described device for filtering and collecting is provided with down blind plate.
Further, the top of described device for filtering and collecting is provided with blind plate.
This device for filtering and collecting impurities in ore slurry pipeline is compared with the traditional filtering gathering-device, has following beneficial effect:
(1) the present invention is owing to a flushometer and recoil water device are set respectively in the both sides of screen pack, this flushometer and recoil water device can effectively wash the foreign material that filter online collection, can cause pump to block after also just having avoided impurities in ore slurry pipeline to enter pump, the generation of inefficacy in service and pump damaged condition, improve the stability of producing, reduced the labour intensity of frequent dismounting filter cleaning.
(2) flushometer of the present invention and the flushing of recoil water device can be carried out also can carrying out when shutting down when the underflow pump operation, and be easy to operate, simple, and filter effective area is increased.The pump operation situation is more stable, more effectively uses.
(3) flushometer of the present invention and recoil water device all adopt many pipelines to be connected in parallel, and make that the flushing area is bigger, and the flushing dynamics is more even, thereby developing result are better.
