Problems solved by technology

Their common disadvantages are: first, the rotating motion of the impeller can easily scatter the sand particles that have settled down, reducing the effect of removing sand particles; The effect is not strong enough without the constraints of the solid boundary. Third, due to the low speed of the impeller, the elution effect of the rotating motion on the organic matter adhered to the sand is not obvious enough.

Abstract

The invention discloses a rotational flow grit chamber with a guide cylinder, which is provided with a main chamber body, wherein one side of the main chamber body is provided with a water inlet and a water outlet respectively communicated with a water conveyance canal, and the side of a chamber wall, close to the water outlet, is provided with a partition plate; a sand collecting hopper is arranged in the center of the bottom of the chamber body, the guide cylinder is arranged above the sand collecting hopper, the lower part of the guide cylinder is of a thick cylinder body, the upper end of the guide cylinder is provided with a thin cylinder body in which a hollow shaft is arranged, the lower end of the hollow shaft is provided with an impeller arranged in the thin cylinder body, the hollow shaft is internally provided with a sand conveying pipe, and the lower end of the sand conveying pipe is communicated with an air lift pump or slurry pump; and the hollow shaft is in transmission connection with a speed-adjustable motor. The rotational flow grit chamber with the guide cylinder is suitable for removing sand grains in a water body in a pipeline or canal, reasonable and perfect in structure and better in sand removal effect as compared with the traditional sand removal device.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a facility for removing sand from rain, flood, sewage, etc. in pipes and channels, a device for separating sand-containing sewage or sand particles in rainwater by sedimentation, and particularly a device A cyclone grit chamber with a guide tube. It can also be used for sand removal of water bodies in various pipelines and channels. Background technique [0002] A large amount of sewage, rainwater and other water bodies in cities are transported or discharged by underground pipes. These water bodies often contain mud and sand, which need to be removed from the water body in time, otherwise it will not only affect the cleanliness and quality of the water body, but also easily block the pipeline and cause damage to the pipeline and ground buildings. In the sewage treatment plant, if the larger particles of sediment are not removed, the subsequent treatment facilities will...
