Grillage machine

Abstract

The invention discloses a grillage machine which comprises a support and a screen drum arranged on the support through a rotating shaft, wherein the inner wall of the screen drum is provided with a spiral guide plate, one end of the rotating shaft positioned at an initiating end of the spiral guide plate is provided with a sleeve, the sleeve may be rotatably sleeved on the rotating shaft, a water accommodating chamber is formed between the sleeve and the rotating shaft and is in fixed connection with a sewage pipeline, the sidewall of the sleeve is provided with a plurality of nozzles, a plurality of water buckets are fixed on the inner wall of the screen drum, and the openings of the water buckets are corresponding to the nozzles. With such a structure, the grillage machine disclosed in the invention has the advantages of a simple structure, small routine maintenance load, no need for extra power during operation and low operation cost.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a grid machine. Background technique [0002] Urban sewage treatment is one of the important infrastructures of a city. Its development level directly affects the health and quality of life of urban residents, and is of great significance to the improvement of urban investment environment and the sustainable development of social economy. [0003] The grid machine is a solid-liquid separation equipment, which can separate solid impurities, particles and other substances in the liquid from the liquid medium. According to the size of the grid mesh, the particle size and size of the separated solid material can be effectively controlled. , so as to ensure the operation index of liquid medium. [0004] The grille machine is also widely used, involving sewage treatment plants, water plants, pumping stations, power plant water inlets, and is widely used in cities to automatic...

AI Technical Summary

Problems solved by technology

However, in the prior art, some common problems of the rotary grill machine are mainly manifested in the following points: 1. The problem of chain damage. The rotation of the drum is driven by the chain driven by the reducer. Chain creep, elongation, corrosion, and fracture are common faults

2. The problem of damage to the reducer. The damage to the reducer mainly includes damage under normal use and chain reaction damage caused by damage to the rollers.

Obviously, the rotary grill machine of the prior art cannot meet the requirement of low energy consumption
