Technical Field

[0001] The utility model relates to the technical field of sewage lifting devices, in particular to a self-cleaning sewage lifting device. Background Art

[0002] A sewage lifting device is a device used to transport lower liquids.

[0003] Existing sewage lifting systems typically utilize a water tank and pumps to extract and transfer sewage. However, sewage often contains contaminants such as grease, which can easily remain and adhere to the inner walls of the water tank. If left uncleaned, these contaminants can gradually accumulate, reducing the effective capacity of the water tank and potentially hindering the proper flow of sewage. Furthermore, large aggregates can break off and be transported along with the sewage, potentially blocking the pipeline and compromising the efficiency of the entire sewage support and delivery system. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the prior art that there are stains such as grease in sewage, which are easily retained and adsorbed on the inner wall of the water tank. Long-term accumulation will reduce the volume of the water tank and even affect the normal introduction of sewage. In addition, large lumps of deposits may fall into the sewage and be transported together with the sewage, which may cause blockage of the conveying pipeline and affect the support and transportation of sewage.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a self-cleaning sewage lifting device, comprising a water tank, a rotating drum is arranged inside the water tank, a plurality of evenly distributed nozzles are arranged on the rotating drum, a spiral water channel is opened inside the water tank, and the input ends of the plurality of nozzles are all arranged in the spiral water channel and are evenly distributed at different heights, the top flange of the rotating drum is connected to an inlet water pipe, the top of the water tank is fixedly connected to a fixing frame, a pump is fixedly installed in the fixing frame, the input end of the pump is fixedly connected to a sewage input pipe, the output end of the pump is fixedly connected to a pump output pipe, and the output end of the pump output pipe is inserted into the water tank.

[0006] As a preferred embodiment, a water inlet cavity is opened in the top of the rotating drum, and the water inlet cavity is connected to the spiral water channel so that external water source can enter the spiral water channel through the water inlet cavity.

[0008] As a preferred embodiment, a filter is fixedly connected to the inside of the water tank, and the filter is arranged away from the pump output pipe. The filter can intercept large pieces of condensate, disperse the large pieces of condensate during flushing, and slow down the accumulation of condensate during transportation.

[0009] As a preferred embodiment, a discharge pipe is fixedly connected to the side of the water tank close to the filter screen, and the ends of the discharge pipe and the sewage input pipe are fixedly connected to connecting flanges. By setting the connecting flanges, the device is easily connected to the external pipeline.

[0010] As a preferred embodiment, a control water valve is fixedly installed inside the water inlet pipe, and the entry of external water source can be controlled by setting the control water valve.

[0011] As a preferred embodiment, the water tank is fixedly connected to a pipeline rack near one end of the sewage inlet pipe. The pipeline rack is fixedly connected to the sewage inlet pipe and provides additional support for the sewage inlet pipe by setting the pipeline rack to prevent the sewage inlet pipe from being loosened from the pump.

[0012] As a preferred embodiment, support feet are fixedly connected to the four corners of the bottom end of the water tank to serve as a support device to prevent friction between the bottom of the device and the ground.
