Novel full-automatic basket filter

Abstract

The invention belongs to the technical field of application of filtering equipment and particularly discloses a novel full-automatic basket filter. The novel full-automatic basket filter comprises landing legs, a filter drum, a drum cover, a speed reducer, a water inlet, a water outlet and a drain outlet. The filter drum is arranged on the landing legs, and the drum cover is arranged on the filter drum. The filter drum is connected with the drum cover through a flange, the speed reducer is arranged on the drum cover, the air inlet is formed in one side of the drum cover, the water outlet is formed in one side of the filter drum, and the dirt outlet is formed in the bottom of the filter drum. The novel full-automatic basket filter has the advantages that the design structure is reasonable, the service life is long, mixed sludge and particle impurities are efficiently filtered during water inflow of a landfill leachate treatment system, mechanical impurities in the mixed sludge are removed through an automatic residue removal structure, the whole leachate is protected against abrasion and blockage in the following operating process, the whole device can normally work and run, and the effects of stabilizing the process course and guaranteeing safety production are achieved. The novel full-automatic basket filter is good in anti-explosion performance, high in use safety coefficient, low in working noise and convenient to clean and maintain.

Description

technical field [0001] The invention belongs to the technical field of filtering equipment application, and in particular relates to a novel full-automatic basket filter, which is suitable for efficient filtering of landfill leachate and meets environmental protection discharge requirements. Background technique [0002] Filter (filter) is an indispensable device on the conveying medium pipeline, and is usually installed at the inlet end of pressure reducing valve, pressure relief valve, fixed water level valve, square filter and other equipment. The filter is composed of a cylinder, a stainless steel filter, a sewage discharge part, a transmission device and an electrical control part. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked. When cleaning is required, just take out the detachable filter cartridge and reinstall it after treatment. The use and maintenance are extremely convenient. [0003] Filters ar...

AI Technical Summary

Problems solved by technology

[0004] In the equipment for filtering sewage, according to the different filter media, mechanical filtration equipment is divided into two types: granular media filtration and fiber filtration. The filter uses the pores between the sand particles to intercept the suspended solids in the water body to achieve filtration, while the high-efficiency asymmetric fiber filtration system uses asymmetric fiber bundle material as the filter material, and the filter material is asymmetric fiber, so that the porosity of the filter bed is very high. It quickly forms a gradient density with a large top and a small bottom, so that the filter has a fast filtration rate and a large sewage interception capacity. It can effectively remove mixed sludge and particulate impurities in landfill leachate. However, the blue filter with a traditional structure has a complicated structure. 1. It is inconvenient to install, disassemble and use. At the same time, it is not easy to control during the filtration operation, and the service life is short and regular maintenance is required, which affects its working efficiency. Moreover, the fiber solid material is not easy to discharge and easy to clog, which reduces the filtration efficiency and quality, which can no longer meet the requirements. The need for high-efficiency filtration and environmental protection treatment of existing landfill leachate for discharge and use, and this is an urgent need to be solved at present
