AI Technical Summary

Technical Problem

In existing sludge flotation cleaning equipment, fine sludge particles or minerals easily adhere to the inner wall of the tank and the outlet of the dissolved air release device, accumulating over a long period of time to form hard scale, resulting in a reduction in effective treatment space and pipe blockage.

Method used

An air flotation cleaning device including a scraping device and an auxiliary device was designed. The scraping device uses a motor to drive a rotating gear and a scraping plate to vibrate and scrape the inner wall. The auxiliary device uses a hydraulic cylinder to drive a push plate to push the sludge, preventing scaling and keeping the tank clean.

Benefits of technology

It effectively prevents scum from caking, ensures the continuity of solid-liquid separation, keeps the inner wall of the tank clean, avoids a decrease in treatment efficiency, and ensures stable effluent quality.

Abstract

The utility model relates to the technical field of air flotation devices, in particular to air flotation cleaning equipment for sludge, which comprises a support frame, the top of the support frame is fixedly connected with an equipment body, the bottom of the equipment body is provided with a sludge outlet, and one side of the equipment body is provided with a dissolved air releaser. According to the device, the scraping device is arranged to drive the rotating shaft to rotate through the output end of the motor, the rotating gear is driven to rotate while rotating, a first rack rod and a second rack rod at the upper end and the lower end of the rotating gear slide in the device body, and when the rotating shaft rotates, the driving bevel gear is driven to rotate; in the operation process, a driven bevel gear is driven to rotate, so that the driven bevel gear drives two lead screws to operate, a sliding block is driven to slide left and right, a scraping plate is driven to scrape off scum on the surface of the scraping plate, and for high-concentration sludge or scum with large viscosity, the scum is prevented from being hardened through continuous operation or high-frequency scraping action of the scraping plate.
