Description

Technical Field

[0001] The utility model relates to the technical field of grit chambers, in particular to a cyclone grit chamber. Background Art

[0002] The cyclone grit chamber is a common equipment used for wastewater treatment, mainly used to remove suspended solid particles and sediments in water. It uses the principle of cyclone to separate solid particles from water through the rotational motion of water flow, thereby achieving solid-liquid separation. Its working principle is to introduce wastewater into the cyclone grit chamber through the water inlet and form a rotating fluid environment inside. Under the action of cyclone, the solid particles in the water will be deposited outward due to the centrifugal force, and finally deposited to the bottom of the pool to form a silt layer. Clean water is extracted from the center of the cyclone, the water quality is improved after sedimentation, and the sand is discharged through the lifting pipe.

[0003] However, in the common cyclone grit chamber, the sand deposited at the bottom of the chamber tends to accumulate thickly and form lumps during operation, which poses a risk of clogging the sand discharge pipe. The sand is also easily attached to the wall of the sedimentation tank, affecting the sedimentation and discharge of the sand. In view of this, we propose a cyclone grit chamber.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] The utility model drives the driving gear to rotate by a motor-driven rotating shaft, so that the sleeve rotates under the meshing of the driven gear and the driving gear, and drives the impeller and the cleaning component to rotate. The impeller in the rotating state can peel off the sand in the water and assist the sand to sink. At the same time, under the rotation of the scraper, the pool wall is cleaned to avoid the sand adhering to the inner wall of the sinking space, resulting in an increase in the wall thickness, which affects and hinders the sinking of the sand. Moreover, under the rotation of the first arc block, the movable plate vibrates through the auxiliary support of the spring during the intermittent contact between the second arc block and the guide block, thereby avoiding the accumulation and agglomeration of the sand after sinking to the bottom, which is conducive to lifting the sand and assisting the sand to enter the sand discharge pipe for discharge, thereby reducing the risk of blockage during the discharge process.
