Description

Water treatment equipment

Technical Field

The utility model relates to a sewage treatment field specifically is a water treatment equipment.

Background

When sewage is treated, a sand-water separator is needed to separate sand from water in the sand-water mixed liquid discharged from the grit chamber. The working process of the existing sand-water separation equipment is as follows: the sand-water mixed liquid enters the water tank from the water inlet pipe, sand and stone in the sand-water mixed liquid are sunk to the bottom of the water tank, the transmission device in the screw conveyor drives the screw shaft to rotate, so that the sand and stone are separated from water, the separated sand and stone are discharged from a sand outlet of the screw conveyor, and the water separated from the sand and stone is discharged from the water outlet pipe. But because the sand and water mixed liquid can impact original liquid in the water tank when entering the water tank, the sand and the stone which originally sink in the water tank are raised by water flow again, and the work efficiency and the separation effect of the sand and water separator are influenced.

Further, the sand and water mixed liquid that just got into in the water tank continuously strikes the baffle, in order to avoid the baffle to warp, the high-end of baffle articulates on the water tank inside wall to make the baffle can slightly swing, simultaneously be provided with the backup pad on the water tank inner wall, the backup pad sets up in the below of baffle low side, be provided with buffer between baffle and the backup pad, buffer also can absorb partial impact force.

Furthermore, the buffer device is an object which can generate certain deformation, such as a spring, and the like, and a corrosion-resistant rubber pad can be adopted.

Furthermore, crossbeams are arranged in the water tank below the baffle at intervals, and the projections of the crossbeams in the vertical direction coincide with the through holes, so that the falling speed of the gravel particles falling from the through holes can be reduced.

Further, in order to further improve the leakproofness, be provided with the recess on the water tank outer wall, be provided with the round cushion between the waterproof board inboard and the recess bottom.

The utility model has the advantages that: be provided with the baffle below the inlet tube, can start the mixed liquid of sand water that just got into in the water tank and stop the effect, reduce its falling speed to avoid the mixed liquid of sand water direct sand and stone contact bottom the water tank, cause the grit resuspension of water tank bottom.

1. The high end of the baffle is hinged on the inner side wall of the water tank, and the bottom end of the baffle is connected with the buffer device, so that the baffle can slightly swing, and the baffle is prevented from being impacted and deformed by sand-water mixed liquid with strong kinetic energy; meanwhile, the baffle can slightly swing, so that sand and stone can be prevented from being clamped in the through hole in a certain length.

2. Be provided with the through-hole that staggers with the inlet tube position on the baffle, the grit that the diameter is less is blockked the back by the baffle, can pass from the through-hole when following the baffle landing, and great grit can't pass the through-hole and can only continue to drop until being blocked the board and give and catch, and the water discharge back in the water tank opens sealing door, takes out and blocks the board, take off the grit granule on it can.
