Grid machine

Abstract

The invention relates to the technical field of sewage treatment, particularly a grid machine which comprises a machine frame, a transmission gear, a chain network, a cleaner, a garbage conveyor and a garbage can, wherein the lower part of the machine frame extends into sewage; the upper part of the machine frame is provided with a cleaning chamber; the chain network can be cleaned in the cleaning chamber; a bracket is arranged below the machine frame; the transmission gear is installed in the middle of the machine frame through a bearing; the chain network is wound on the transmission gear; the cleaner is arranged in the cleaning chamber on the upper part of the machine frame; the garbage conveyor is arranged below the cleaning chamber; the garbage can is positioned on the right end of the garbage conveyor; and the garbage conveyor conveys the flushed dirt into the garbage can. The grid machine can adsorb small-granule suspended substances, has high decontamination capacity, can clean the chain network, has the advantages of higher decontamination efficiency, simple structure and lighter weight, and is convenient for transportation and popularization.

[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industrial wastewater treatment plants and other water intake structures and water pump stations has gradually been replaced by The mode of mechanical operation replaces manual operation.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

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

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.
