Filtering and deslagging device

Abstract

The invention relates to a filtering and deslagging device. The device comprises a raw material cache bin, a shell filter, a spiral shaft and a sewage pump, wherein the shell filter is arranged in the raw material cache bin; the spiral shaft is arranged in the shell filter and is connected with the output end of a speed reducer; the input end of the speed reducer is connected with the output end of a motor; a spiral blade is arranged on the spiral shaft; the shell filter is communicated with a feeding port formed in the side wall of the raw material cache bin; a deslagging port is formed in the shell filter; a plurality of discharging holes are formed in the surface of the shell filter; the sewage pump is used for outputting materials in the raw material cache bin to the outside of the raw material cache bin. According to the filtering and deslagging device, impurities can be removed to a large extent, and the normal operation of subsequent equipment is guaranteed; the device is simple in structure and easy and convenient to operate and maintain; the impurities do not need to be manually removed, so that manpower input is reduced; the sizes of the discharging holes of the shell filter can be adjusted according to different materials to be filtered, so that the effect is stable and reliable and the device is easy to popularize; by virtue of the device, large-scale continuous production operation also can be carried out.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular to a filter and slag removal device applied to urban dewatered sludge, kitchen waste, sludge in rivers, seas, lakes and ponds, and the like. Background technique [0002] Municipal sludge is the product of urban sewage treatment process. The current sewage treatment technology transfers a large amount of pollutants in sewage to sludge through microbial metabolism and physical and chemical methods to achieve the purpose of purifying water quality. Silt in rivers, seas, lakes and ponds is formed by the deposition of sediment, animal and plant debris in the flowing water environment through physical and chemical actions. Kitchen waste is the domestic waste formed by residents in the process of living consumption, which is easily rotten and deteriorated, emits foul smell, and spreads bacteria and viruses. [0003] Municipal dewatered sludge, kitchen waste, and sludge ...

AI Technical Summary

Problems solved by technology

When processing and disposing of the above pollutants, these sundries often cause rapid wear of pumps, valves, pipelines and other equipment, and even cause blockage and cause them to malfunction

Some existing filtering equipment such as grilles and mechanical filtering equipment are only aimed at highly mobile sewage or low-concentration muddy water, and cannot be used for such pollutants with high concentration, poor fluidity and high viscosity
