A sand washing mud dehydration system

Abstract

The invention discloses a sand washing mud dehydration system, which comprises: a plate and frame filter press and a gravity concentration device, and the plate and frame filter press includes: a frame, a thrust plate, a filter press plate group and a push-pull structure; wherein, the thrust The plate is fixed at one end of the frame; the filter plate group is set adjacent to the thrust plate, and the bottom of the filter plate group is slidingly connected with both sides of the frame; the push-pull structure is fixed with the filter plate group and slides with the top surface of the frame connection; a mud conveyor belt is set at the bottom of the frame, and the gravity thickening device is set adjacent to the downstream of the mud conveyor belt; the dehydration system processes the sand washing mud through two procedures of plate and frame pressure filtration and gravity concentration, and improves the plate and frame pressure at the same time. The structure of the filter and the gravity concentration device improves the removal rate of water in the mud, effectively improves the dehydration effect, and avoids the pollution of the mud to the environment.

Description

Technical field [0001] The present invention relates to the field of mud dehydration techniques, and more particularly to a sanding mud dehydration system. Background technique [0002] Suliling mud, as the name suggests, the sand washing machine in the mud produced during the process of washing the artificial sand or natural sand, there is a large amount of water in the sanding mud, and if it is not treated or improperly handled, it is discharged, the interior of the mud Long-term hypoxia and water sufficient environments will make a large amount of microorganisms in the mud, which is easy to cause secondary pollution to the environment. [0003] In the prior art, the washing mud is treated, but it is simply a strip pressure filter or gravity concentration; the water filtration rate of the belt filter press is still high, resulting in mud unable to form solid-state foreign transport. And because the mud requires a large stacking site, the surrounding environment also causes poll...

Problems solved by technology

[0002] Sand washing mud, as the name suggests, is the mud produced by the sand washing machine during the process of cleaning artificial sand or natural sand. There is a large amount of water in the sand washing mud. If it is not treated or treated properly and it is discharged, the inside of the mud will A long-term lack of oxygen and sufficient water will cause a large number of microorganisms to grow in the mud, which will easily cause secondary pollution to the environment

[0003] In the prior art, when the sand washing mud is processed, it is simply belt-type filter press or gravity concentration; the water content of the mud filtered by the belt filter press is still high, so that the mud cannot be transported in a solid state. And because the mud requires a large storage space, it also pollutes the surrounding environment; the gravity concentration equipment can concentrate the water in the mud, but because the mud will dry out after concentration, it is easy to block the feed port and reduce the impact on the mud. concentration efficiency
