Sewage impurity removal device

Abstract

The invention relates to the technical field of sewage treatment and in particular relates to a sewage impurity removal device, which comprises a rack, a filter screen, a garbage collection device and a garbage cleaning device, wherein an impurity discharging opening is formed in the upper part of the rack, and garbage is discharged through the impurity discharging opening; slots are symmetrically formed in the left and right at the rear side of the rack; the filter screen is arranged in the slots; the garbage collection device is arranged in the front of the filter screen and is vertically arranged on the rack; the garbage collection device is used for collecting the garbage intercepted by the filter screen; the garbage cleaning device is horizontally arranged above the rack and penetrates through the impurity discharging opening; the garbage cleaning device is used for cleaning the garbage collected through the garbage collection device, so as to facilitate next garbage collection. According to the sewage impurity removal device, the solid garbage in sewage can be cleaned, and drain pipes or channels can be prevented from being blocked; the cleaning effect is relatively good; the sewage impurity removal device is simple in structure and easy to maintain and the production cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage impurity removal device. Background technique [0002] Since the early 1970s, with the technological development of my country's water treatment industry, the grid cleaning work of waterworks, sewage treatment plants, power plants, water conservancy projects, industrial wastewater treatment plants and other water intake structures and water pump stations has gradually been replaced by The mode of mechanical operation replaces manual operation. As a result, related mechanical equipment emerges at the historic moment, and its types tend to be diversified. In the history of sewage treatment, various grilles have their advantages and disadvantages. Traditional grilles generally have filtration The accuracy is not high, the slag unloading is difficult, and the wear is serious after a long time of use.

Problems solved by technology

[0002] Since the early 1970s, with the technological development of my country's water treatment industry, the grid cleaning work of waterworks, sewage treatment plants, power plants, water conservancy projects, industrial wastewater treatment plants and other water intake structures and water pump stations has gradually been replaced by The mode of mechanical operation replaces manual operation. As a result, related mechanical equipment emerges at the historic moment, and its types tend to be diversified. In the history of sewage treatment, various grilles have their advantages and disadvantages. Traditional grilles generally have filtration The accuracy is not high, the slag unloading is difficult, and the wear is serious after a long time of use. For example, the rotary rake tooth decontamination machine can only reach 60% of the slag unloading rate under normal circumstances, and it can reach up to 90% after adding a rotary brush. The rotating brush is easy to drag and hang the slag, causing the slag to hang on the rake teeth, which is easy to break or pull the rake teeth, resulting in increased maintenance costs and reduced slag blocking effect; the unloaded slag is impacted by water and falls on the grille Rear, causing damage to water pumps, etc., and affecting the main body treatment process

In addition, the structure of the rotary rake-tooth grill decontamination machine is relatively complex, and there are multiple sets of rollers, gaskets, baffles, rake teeth, guide rails and other rotating and related components, which increase the cost of maintenance

Therefore, there are still some defects in the structure and function of the rotary rake tooth decontamination machine.
