Description

Sludge return device for non-energy-consuming sewage treatment equipment

The utility model relates to a sludge return device, in particular to a sludge return device for non-energy-consuming sewage treatment equipment.

In the treatment of sludge in the sewage tank, especially the long running time of the filter device, it is easy to cause blockage, affecting the effect and use function of the sewage treatment. The tank cover must be opened, and the tank must be cleaned by people, which is time-consuming and labor-intensive. At the same time, the working conditions are poor and unhygienic. The patent of patent application No. 94223710 discloses "a kind of sewage treatment equipment", still exists above-mentioned weak point.

The purpose of the utility model is to provide a sludge return device for non-energy-consuming sewage treatment equipment with simple structure, convenient management, adopting a one-way sludge valve, and sludge can only flow in one direction.

The purpose of this utility model is achieved in this way, including a sewage discharge tank and a sludge sedimentation tank. A one-way sewage pump is installed in the lower part of the sewage discharge tank, and the output end of the sewage pump is connected with a sewage discharge pipe leading to the outside of the sewage discharge tank. There is a water inlet hole on the upper part of the partition wall between the mud sedimentation tanks, and there is a vertical partition wall in the sludge sedimentation tank. The upper part of the vertical partition wall is equipped with a filter water inlet pipe, and the filter water inlet pipe is inserted at the bottom of the filter container with granular filter material. The lower part of the sedimentation tank is equipped with a sludge return pipe leading to the sewage tank, the sludge return pipe is equipped with a one-way sludge valve, and there is a water outlet on the upper part of another partition wall.

In the utility model, the sewage pump is regularly put into the sewage tank, and the sewage pump is used to discharge the sludge in one direction all the time. The water pipe makes the sewage in the middle and upper layers enter the filter container equipped with granular filter material, and the filtered sewage flows out from the water outlet, while the remaining sludge naturally settles down, passes through the sludge return pipe through the one-way sludge valve, and flows to the sewage discharge pipe. In the pool, discharge regularly.

The utility model has the characteristics of simple and compact structure, convenient manufacture and use, simple and convenient management, safety and reliability, long cleaning period, no blockage, no recoil, no special management and the like.

Below in conjunction with accompanying drawing, the utility model is further described.

Accompanying drawing is the utility model sectional structure schematic diagram.

As shown in the drawings, the sewage tank 1 is equipped with a sewage pump 2 and a sewage pipe 3, and the sludge settling tank 10 is equipped with a one-way sludge valve 5 and a sludge return pipe 4, and there is a filter inlet pipe 7 and a device in the middle. There is a filter container 6 with a particle filter material 8, and a water outlet 9 is arranged on the top.
