Efficient anti-blocking rotational flow grit chamber device

Abstract

The invention discloses an efficient anti-blocking rotational flow grit chamber device, and belongs to the technical field of grit chamber degritting, the efficient anti-blocking rotational flow grit chamber device comprises a hollow grit chamber body with a bottom opening, a control device, a Roots blower, a grit-water separator and a multi-stage high-pressure centrifugal pump, the top of the grit chamber body is fixedly connected with a cover plate; a driving device is mounted at the top of the cover plate, and a driving shaft of the driving device penetrates through the cover plate and is connected with propeller blades. According to the anti-blocking rotational flow grit chamber device, water is rapidly conveyed to the sealing device in the grit chamber body through the multi-stage high-pressure centrifugal pump, high-pressure water flow is used for dispersing caked sand grains deposited on the surface of the sealing device, and the positions of the sand grains can be lifted, sand in the grit chamber body is conveyed into the grit-water separator by the sand lifting assembly, unsmooth sand discharge, blockage and other phenomena are avoided, manual regular cleaning of the interior of the grit chamber body is not needed, and a large amount of manpower and material resources are saved.

Description

technical field [0001] The invention relates to the technical field of sand removal in grit chambers, and more specifically relates to a high-efficiency anti-blocking cyclone grit chamber device. Background technique [0002] The swirl grit chamber is a grit settling device that uses mechanical force to control the flow pattern and velocity of the water, accelerate the sedimentation of sand particles, and take the organic matter away with the water flow. The grit chamber is composed of an inflow port, an outflow port, a grit chamber, a sand bucket, a turbine drive, and a sand discharge system. Sewage flows into the grit chamber from the tangent direction of the inflow inlet. A drop weir is set in the water inlet channel to make the sand that may be deposited at the bottom of the channel slide down into the grit chamber; Pop to the bottom of the pool and strengthen the wall effect. There is an adjustable speed paddle in the middle of the grit chamber to keep the water in th...

Problems solved by technology

[0006] However, during the operation of the cyclone grit chamber, due to the different sizes of sand particles in the water, compressed air cannot lift all the sand particles from the inner bottom of the grit chamber body, resulting in the gradual accumulation of some larger sand particles. In the grit chamber, the plates are agglomerated and cannot be transported to the sand-water separator by the sand pump, often causing poor sand discharge and clogging, and it is necessary to spend a lot of manual cleaning of the grit chamber after emptying. deposits to restart the run
