Domestic sewage treatment device

Abstract

The invention discloses a domestic sewage treatment device. The domestic sewage treatment device comprises a box body, wherein support columns are respectively arranged at the left side and right sideof the lower end of the box body; a universal wheel is arranged at the lower end of each support column; a motor box I is arranged at the right side of the upper end of the box body; a motor I is arranged in the motor box I; the lower end of the motor I is connected with a rotary shaft I; the lower end of the rotary shaft I penetrates through the top part of the box body, and a main gear is arranged at the lower end of the rotary shaft I. The domestic sewage treatment device has the advantages that in the working process, the motor I works to drive the rotary shaft I to rotate, so that the main gear drives a driven gear to rotate, a screw rod is rotated, a slide seat is slide left and right, an electric telescopic rod and a scraping plate are driven to move, and the impurities on a filterplate are cleared, so that the influence to the filtering effect due to blockage of the filter plate by the impurities is avoided; the filter plate and the fixed block are detachably connected, and acorresponding movable plate is arranged at the outer side of the box body, so that the filter plate can be conveniently cleaned and repaired, and the service life of the filter plate is prolonged; the sewage treatment effect is guaranteed, and the practicality is strong.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a domestic sewage treatment device. Background technique [0002] Domestic sewage is the wastewater discharged from residents' daily life, mainly kitchen and laundry wastewater. Direct discharge in this type of wastewater will cause acid and alkali pollution, change the pH of the water body, destroy its buffering effect, eliminate or inhibit the growth of microorganisms, and hinder the self-purification of the water body. [0003] Therefore, in the treatment of domestic sewage, it is generally neutralized. Existing domestic sewage treatment devices usually have this function. However, there will be more sundries in domestic sewage. When filtering it, it is easy to cause blockage of the filter screen and affect the purification effect of the device. It is inconvenient to replace and clean up, and the sundries cannot be collected and cleaned up centrally. Therefore, those sk...
