A sewage dispersion pretreatment device

Abstract

The invention belongs to the technical field of sewage intermediate treatment, especially a sewage dispersion pretreatment device. Aiming at the problem that the filter mechanism of the traditional sewage filter device is easy to be blocked and manual cleaning is required, the following scheme is proposed, including a water separation cylinder welded at the end The sewage input pipe and the treatment box, the inside of the water-splitting cylinder is equipped with a water-splitting mechanism, and the inner wall of the treatment box is equipped with a self-cleaning filter mechanism, and the water-splitting mechanism includes a fixed ring plate welded to the inner bottom of the water-splitting cylinder and The conical plate welded to the top of the water distribution cylinder, and the water distribution cylinder is provided with a water receiving end. The invention can make use of the narrow tube effect to concentrate the sewage to form an impact on the paddle, which is beneficial to ensure the rotation of the water receiving end; by providing a spiral groove at the impact end, it can cooperate with the annular body, The setting of the inclined pulley makes the cone-shaped filter cartridge rotate, and the filter end is brushed by the brush rod.

Description

technical field [0001] The invention relates to the technical field of sewage intermediate treatment, in particular to a sewage dispersion pretreatment device. Background technique [0002] Sewage refers to the effluent water from domestic and production that is polluted to a certain extent. Water that has lost its original function is simply called sewage. It is mainly the water after daily use, which contains more organic matter and is easier to handle. Domestic sewage, sewage from livestock and poultry farms, and wastewater discharged from tanning, wool washing, slaughtering and hospitals often contain various pathogens, such as viruses, germs, and parasites. Contamination of water bodies with pathogens can spread disease. During the purification treatment of domestic sewage, different degrees of filtration treatment are often required. [0003] Domestic sewage needs to be finely filtered after removing larger debris in advance. The traditional filter device filter me...

Problems solved by technology

[0003] Domestic sewage needs to be finely filtered after removing larger debris in advance. The traditional filter device filter mechanism is often concentrated due to the input of sewage from pipelines, resulting in a small actual range of action of the filter mechanism, and the filter holes are easy to filter. If it is clogged, it needs to be cleaned manually from time to time, otherwise it will have a great impact on the filtering effect
