Description

Technical Field

[0001] The utility model belongs to the field of sewage lifters, and specifically relates to a sewage lifter with a slag-water separation structure. Background Art

[0002] Sewage treatment has always been a headache. The traditional approach is to dig a collection well underground and place a sewage pump in the well, which is also commonly known as one pit and two pumps. The sewage treatment method of one pit and two pumps has drawbacks such as odor, easy blockage of the sewage pump, difficulty in cleaning the sewage pit, and pollution of the surrounding environment. The sewage lift replaces the equipment for discharging underground sewage with one pit and two pumps, and completely solves the history of sewage blockage and difficulty in cleaning in one pit and two pumps. The sewage lift can isolate the debris in the sewage in the separator through the debris separator, and the water filtered out the debris flows through the pump cavity to the casing, so that the debris has no direct contact with the pump impeller, completely solving the historical problems of pump impeller entanglement, blockage, heavy load, etc.

[0003] The patent application with announcement number CN218879486U discloses a sewage lift, comprising: a casing, a gear ring rotatably arranged at the central top of the fixing frame, a dirt separation cylinder fixedly arranged at the bottom end of the gear ring, a first gear fixedly arranged at the end of the main shaft of the reduction motor, a bottom sealing disk horizontally rotatably arranged at the upper end of the inner side of the bottom shell body, and a submersible sewage pump fixedly arranged at the lower left corner of the inner side of the casing. The device discharges sewage from the center of the gear ring, turns on the reduction motor so that the gear ring drives the dirt separation cylinder to separate the solid and liquid of the sewage, and the dirty liquid enters the casing. At the same time as the dirty liquid is separated, the submersible sewage pump is turned on to discharge the liquid. After the solid-liquid separation is completed, the reduction motor is turned off and the electric telescopic rod is turned on so that the rack drives the second gear to rotate, and then the bottom sealing disk rotates to the lower right, and debris can be quickly discharged from the discharge pipe. The device greatly reduces the volume of the sewage lift, is more convenient to install, and has a simple structure, is durable and easy to maintain.

[0004] However, the above-mentioned comparative documents have the following disadvantages when used:

[0005] According to the description in paragraph 0031 of the comparative document, "When in use, the device discharges sewage from the mouth in the center of the gear ring 3 into the device, and then turns on the reduction motor 6, which drives the first gear 7 to rotate. After the first gear 7 rotates, it drives the gear ring 3 to rotate, and the gear ring 3 drives the dirt separation cylinder 4 to rotate synchronously, and solid-liquid separation is carried out in the dirt separation cylinder 4. The separated sewage enters the box body 1, and the sewage is extracted by turning on the submersible sewage pump 9, and then the liquid is discharged through the outlet pipe 10." It can be seen that the sewage needs to be separated by the dirt separation cylinder 4, and when the sewage is separated, impurities will accumulate inside the filter holes on the outer wall of the dirt separation cylinder 4, thereby affecting the efficiency of sewage separation.

[0006] Therefore, a sewage lifter with a slag-water separation structure is proposed to solve the above-mentioned drawbacks. Utility Model Content
