Rotary network chain type grid cleaner

Abstract

The invention relates to a rotary network chain type grid cleaner, comprising a rack and a speed-reducing motor arranged at the top part of the rack, wherein the output end of the speed-reducing motor is connected with a drive chain wheel group which is connected with a driving chain wheel group through a chain; a main shaft is arranged in the middle of the driving chain wheel group and two ends of the main shaft are provided with main shaft guide wheels; an underwater guide wheel is arranged at the tail part of the rack and a chain network is arranged between the main shaft guide wheels and the underwater guide wheel; a slag brushing chain wheel group is arranged below the main shaft guide wheels and the chain network comprises two main chains and a steel wire gridding; the steel wire gridding is formed by annularly connecting steel wires; and a gap reserved between the steel wires is more than 1 mm and a roller chain supporting plate is arranged below the chain network. The rotary network chain type grid cleaner has the advantages of simple structure, high slag unloading efficiency, wide grid gap size and fewer structural parts.

Description

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industrial wastewater treatment plants and other water intake structures and water pump stations has gradually been replaced by The mode of mechanical operation replaces manual operation.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., will affect the main treatment process

Generally, the limit precision of slag blocking by the rotary rake-tooth grille decontamination machine is 5mm, which leads to the inability to intercept fine suspended matter and affects the overall process effect.

Furthermore, the structure of the rotary rake-tooth grille decontamination machine is more complicated, 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.
