Household domestic sewage treatment method and device

Abstract

The invention relates to a household domestic sewage treatment device. The household domestic sewage treatment device comprises a grinding device, a collecting device and a cutting device, wherein the grinding device is provided with a grinding disc and a grinding cylinder; a plurality of guide grooves are formed in the inner wall of the grinding cylinder; the grinding disc is arranged at the lower part of the inner side of the grinding cylinder; a collecting groove is formed in a shell and is positioned on the outer side of the grinding cylinder; the cutting device comprises a cutting shaft and a plurality of cutting knife groups, and comprises a cutting fixed knife and two cutting rotary knives; the cutting fixed knife is connected with a torsional spring for preventing the cutting fixed knife from rotating; and the outer end of each cutting fixed knife is inserted into one guide groove. According to the household domestic sewage treatment method and device, the cutting fixed knife is matched with the cutting rotary knives, so that the crushing efficiency is improved; garbage with the hardness greater than a preset value is pushed to grinding teeth after being cut once, and the garbage with the hardness greater than the preset value and the volume greater than the preset value is automatically sorted through the clamping action of the cutting knife groups.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a domestic sewage treatment method and device thereof. Background technique [0002] Washing vegetable leaves or tableware in daily life will produce a lot of sewage, which contains leftovers. If it is poured directly into the sewer, it will cause blockage of the sewer pipe, and if the sewage is poured into the sewer before it flows into the sewer The removal of garbage brings unnecessary troubles to people's lives. Even if the larger garbage in the sewage is taken out for crushing, the crushing device may also be stuck due to the high hardness of the garbage, and cannot be processed according to the size of the garbage. Choose the appropriate crushing method for hardness, and the crushing efficiency of flexible impurities whose hardness is lower than the preset value is low, which affects the user experience. Contents of the invention [0003] The invention provides ...
