A worm fan type sand washing sand water separation device and its processing method

Abstract

The invention relates to a snail fan type sand washing, sand and water separation device and a processing method thereof, which comprises step 1: starting the body of the sand washing, sand and water separator, and inputting sewage into the body of the sand washing, sand and water separator; step 2: washing the sand The sand from the outlet of the water separator body is passed to the sand inlet and enters the sand delivery pipe, and the screw conveyor is driven to rotate, so that the sand is conveyed to the sand outlet; Step 3: Start the driving part and send it out from the sand outlet The sand falls into the inner cylinder from the material opening, and the synchronous motor is started at the same time; Step 4: Close the driving part, start the sand suction pump; Step 5: Drive the driving part, the sand stored in the storage bucket falls into the inner cylinder from the material opening, and simultaneously drive synchronous motor. The invention improves the sand-water separation effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a worm fan type sand washing sand water separation device and a processing method thereof. Background technique [0002] At present, the spiral sand-water separator is a kind of equipment used in the grit chamber of the sewage treatment plant. The sand washing function is added to the separator to reduce the odor of sand discharge. [0003] Existing, such as the Chinese patent literature publication number is CN107262266B, the patent name is a kind of turbofan type sand washing sand water separation device, including a spiral sand water separator, the spiral sand water separator includes a water collection tank, a U-shaped The conveying trough and the screw conveyor, the U-shaped conveying trough is set with a low left and a right high, and the water collecting tank is arranged directly above the left end of the U-shaped conveying trough, and a diversion area and a sett...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: after the sand washing sand water separation device settles in the settling zone, the separated sand particles are transported in the U-shaped conveyor, but after the sand washing sand water separation device has been used for a period of time There will be water in the separated sand particles, which will make the overall separation effect poor
