AI Technical Summary

Technical Problem

In existing sewage treatment processes, fibrous objects and aquatic plants on the agitator are easily entangled, leading to increased cleaning workload and reduced treatment efficiency. At the same time, sand and gravel debris at the bottom of the sedimentation tank are not easily discharged.

Method used

A vortex sedimentation tank comprising a crushing box and spiral blades was designed. The crushing box crushes fibrous objects and weeds, while the spiral blades and sealing plugs facilitate the discharge of sand and gravel. Combined with a scraper, the sediment is cleaned, preventing debris from tangling and accumulating.

Benefits of technology

This effectively avoids frequent cleaning of the mixing paddle, improves sewage treatment efficiency, ensures smooth discharge of sand and gravel, and reduces the amount of manual maintenance required.

Abstract

This utility model belongs to the field of wastewater treatment technology, specifically relating to a vortex grit chamber for wastewater treatment. It includes a grit chamber body with an inlet pipe and an outlet pipe connected to it. A sand discharge pipe connects to the bottom of the grit chamber body. A top plate is installed on the top of the grit chamber body, and a pulverizing box is fixedly connected to the top of the top plate. A filter screen is fixedly connected inside the pulverizing box. The bottom of the pulverizing box is connected to the inlet pipe, and a cover is fixedly connected to the top of the pulverizing box. A first motor is fixedly installed on the cover, and a first rotating shaft is fixedly connected to the output end of the first motor. Multiple pulverizing blades are fixedly connected to the outer bottom side of the first rotating shaft extending into the interior of the pulverizing box. A water supply pipe connects to the cover. This facilitates the pulverization of fibrous objects, weeds, and other debris in the wastewater, preventing these objects from tangling on the propeller, reducing the need for frequent propeller cleaning, lowering workload, and improving wastewater treatment efficiency.
