A sedimentation device for wastewater treatment

By adopting a design that combines a central pipe with a vertical cylinder and honeycomb inclined tubes to optimize the water flow path in the wastewater treatment equipment, and combining a geared motor to drive anti-clogging blades and an electronic valve to control sludge discharge, the problem of low solid-liquid separation efficiency in traditional oil well wastewater treatment sedimentation tanks has been solved. This has achieved efficient solid-liquid separation and easy sludge discharge, reducing operation and maintenance costs.

AI Technical Summary

Technical Problem

Traditional oil well wastewater treatment sedimentation tanks have low solid-liquid separation efficiency, and wastewater is prone to short-circuiting and turbulence. The sludge discharge system is also imperfect, resulting in effluent quality that is difficult to meet standards and high operation and maintenance costs.

Method used

The design employs a central tube and a vertical cylinder, combined with honeycomb inclined tubes to optimize the water flow path and form a stable laminar flow. A geared motor drives the anti-clogging blades to rotate, and an electronically controlled sludge discharge pipe is used to achieve efficient solid-liquid separation and convenient sludge discharge.

Benefits of technology

It significantly improves solid-liquid separation efficiency, reduces short-circuiting and turbulence, lowers operation and maintenance costs, ensures the continuity of the treatment process and the quality of effluent, and simplifies manual cleaning work.

Abstract

This utility model discloses a sedimentation device for wastewater treatment, including a vertical cylinder. An I-beam is fixedly connected inside the vertical cylinder, and a geared motor is fixedly connected to the top of the I-beam. A vertical shaft is fixedly connected to the bottom of the output shaft of the geared motor, and two anti-clogging blades are fixedly connected to the outer wall of the vertical shaft. An overflow hood is fixedly connected inside the vertical cylinder. This utility model, through the cooperation of a central pipe and the vertical cylinder, combined with honeycomb inclined tubes to optimize the water flow path, transforms vertical water flow into stable laminar flow, significantly reducing short-circuiting and turbulence, accelerating the settling of pollutant particles, and greatly improving solid-liquid separation efficiency and effluent quality. The electronically controlled sludge discharge pipe, combined with water pressure sludge discharge, is simple and efficient to operate. The geared motor drives the anti-clogging blades to rotate, effectively preventing large particles of impurities from clogging the sludge discharge port, reducing the frequency of manual cleaning, ensuring the continuity of the treatment process, and significantly reducing operation and maintenance costs.
