In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a multistage filter auger of sewage treatment machine, includes motor, pivot, helical blade, casing, water inlet and row's cinder notch, the pivot is connected to the motor, is equipped with helical blade in the pivot, the water inlet sets up in the initiating terminal top of pivot, and row's cinder notch sets up in the terminal below of pivot, the casing includes the open V type casing in first top and the filter housing of lower half, filter housing first half section and seted up the coarse filtration hole, later half section has seted up the fine filtration hole. When sewage flowed in from the water inlet, great pollutant in the sewage can't pass through the coarse filtration hole of filtering the casing, it discharges to arranging the cinder notch to be taken by the helical blade, surplus sewage enters into the deposit room of sewage treatment machine from the coarse filtration hole, treat that the scraper blade slag salvaging device in the deposit room transports the sewage that has the precipitate once more to the open V type casing in top, make sewage get into the multistage filtration auger once more, the pollutant that is greater than the fine filtration hole in the sewage will be transported to arranging the cinder notch by helical blade and discharge, set up the first half of casing into the V type and both can increase the inflow, can prevent the fluctuation of inflow simultaneously, play buffer treatment's effect, coarse, fine filtration hole's setting makes sewage form multi-stage filtration, the filter effect of sewage has been improved.

Preferably, the spiral blades are uniformly distributed with water permeable holes. The spiral blades are provided with water permeable holes, so that the resistance of sewage delivery is reduced.

Preferably, the helical blade comprises a forward helical blade and a reverse helical blade, and the reverse helical blade is arranged at the tail end of the rotating shaft. The reverse helical blade can prevent filter residue from accumulating at the tail part, and avoid forming a slag discharge dead angle.

Preferably, two ends of the filtering shell are fixedly connected with the inner wall of the sewage treatment machine by flanges. And the two ends are connected by flanges, so that the shell is convenient to disassemble, and the maintenance difficulty is reduced.

Preferably, the coarse filtering holes and the fine filtering holes are both arranged in an inverted cone shape. The inverted cone type filtering holes are high in filtering efficiency, small in liquid penetration resistance and capable of improving liquid flow rate.

Compared with the prior art, the utility model has the following advantages:

utilize this to filter the auger and can carry out multistage filtration processing with sewage, make the structure of equipment compacter, reduced the manufacturing cost of equipment, optimized sewage treatment process, alleviateed the work load of equipment, reduced the trouble incidence of equipment, the reuse of the sewage of being convenient for has improved water resource utilization.
