Grit-water separator

Abstract

The invention provides a grit-water separator. The grit-water separator comprises a water tank, a water inlet pipe, a drain pipe, a U-shaped groove, a shaftless screw, a drive device and a partition board, wherein the water inlet pipe, the drain pipe and the U-shaped groove are connected with the water tank; the U-shaped groove is inclined, one end is connected with the bottom end of the water tank, the other end is higher than the liquid level of the water tank, and a grit outlet is formed in the top end of the U-shaped groove; the shaftless screw is arranged in the U-shaped groove and in drive connection with the drive device; the partition board is arranged obliquely, one end is higher than the liquid level of the water tank, the other end gets close to the side wall of the water tank, and a gap is reserved between the other end and the side wall; the water inlet pipe and the drain pipe are arranged on two sides of the partition board. By means of the partition board arranged between the water inlet pipe and the drain pipe, impact produced by water when the water enters the water inlet pipe is blocked by the partition board and cannot reach the drain pipe directly, so that grit is settled more sufficiently, and the grit-water separation effect is improved.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a sand-water separator. Background technique [0002] In the process of industrial production or water treatment, in order to meet the needs of large-scale production, the amount of water delivery is relatively large, so that the water carries a large amount of sand and gravel. If water containing a large amount of sand and gravel is directly supplied to the equipment, it is very easy to cause the equipment to get stuck or wear out. Therefore, the water must be treated first to reduce the sand and gravel content in the water. [0003] The current treatment method is usually to introduce the feed water into the sand-water separator, and after the large-grained sand is precipitated, the clean water will flow out and be transported to the next link. The sand that settles to the bottom of the water is discharged through the screw conveyor to realize the separation of sand an...

AI Technical Summary

Problems solved by technology

The problem is that when the sand-water separator is working, the impact of the incoming water is large, and the sand and water in the separator flow violently, which is not conducive to the settlement of the pre-solid gravel, and even the settled gravel will be washed up by the water flow and suspended in the water, making the separator Sand water separation effect is not good
