Large sewage pumps are generally equipped with automatic coupling devices for automatic installation, which makes installation and maintenance quite convenient. They can run continuously for a long time.

[0003] In existing sewage pumps, the pump body is usually placed in the mud bottom, and then the pump is started. When the pump is started, the sewage begins to be pumped out and pushed to a high place or a pipe. The motor drives the impeller to rotate, generating centrifugal force, thereby achieving the purpose of sewage discharge.

[0004] However, this method still has some defects. Due to the large amount of impurities at the bottom of the sludge, some difficult-to-absorb sludge often damages the stirring blades, causing serious damage to the machine. The damaged stirring blades will affect the stirring efficiency, resulting in a decrease in the sewage treatment speed.

In actual use, the staff energizes the device, and then the operation of the drive motor 106 can drive the auger 105 to rotate counterclockwise. When the auger 105 rotates, the sewage can be sucked into the pump body 114 through the water inlet pipe 104, and as the auger 105 rotates, the sewage is discharged from the pump body 114 through the drain pipe 101.

[0026] Through the compact overall design, the shell 100, drive motor 106, water inlet pipe 104, drain pipe 101 and other components are rationally arranged inside the pump body 114, saving space and facilitating installation and maintenance. The drive motor 106 drives the auger 105 to rotate counterclockwise to effectively suck in sewage and discharge it, and the operation is simple and efficient.

[0027] Second embodiment:

[0028] like Figure 2-3As shown, a filter screen 107 is detachably fixed to the bottom end of the pump body 114, a bottom plate 103 is fixed to the side of the filter screen 107 away from the pump body 114, a rotating rod 108 is fixed to the bottom end of the auger 105, the bottom end of the rotating rod 108 passes through and extends into the filter screen 107, a plurality of stirring plates 3 are fixed on the outer periphery of the rotating rod 108 located in the filter screen 107, and the stirring plates 3 are evenly spaced on the outer periphery of the rotating rod 108. In actual use, the rotation of the auger 105 can drive the rotating rod 108 and the stirring blades to rotate, thereby mixing the sludge with the water, so as to effectively separate the water and the dirt. At the same time, during the rotation of the stirring blades, the filter screen 107 can protect the rotation of the stirring blades to avoid interference with the stirring of the stirring blades, and the detachable filter screen 107 can also be easily cleaned.

[0029] Through the structural design of the filter screen 107, the bottom plate 103 and the stirring plate 102, impurities in the sewage can be effectively mixed and filtered, the pump body 114 and the auger 105 can be protected, and the maintenance cost and failure rate can be reduced.

[0030] Third embodiment:

[0031] like Figure 2-3 As shown, a groove 110 is provided at the bottom end of the pump body 114, and the filter 107 is slidably inserted in the groove 110. Symmetrical bolts 109 are threadedly connected on the outer periphery of the pump body 114. The bolts 109 penetrate and extend into the filter 107 and are threadedly connected to the filter 107. In actual use, the staff only needs to rotate the bolts 109 to release the connection between the filter 107 and the groove 110, thereby separating the filter 107 from the pump body 114.

[0032] The provided bolts 109 cooperate with the filter screen 107 to facilitate quick installation and removal of the filter screen 107 .

[0033] Fourth embodiment:

[0034] like Figure 4As shown, a rotating sleeve 111 is threadedly connected on the outer circumference of the water inlet pipe 104 near its bottom end, and a through hole 113 is opened at the bottom end of the rotating sleeve 111. A filter plate 112 is connected between the water inlet pipe 104 and the through hole 113. The water inlet pipe 104 is an L-shaped pipe.

[0038] Working principle: During actual use, the staff energizes the device, and then the operation of the drive motor 106 can drive the auger 105 to rotate counterclockwise. When the auger 105 rotates, the sewage can be sucked into the pump body 114 through the water inlet pipe 104, and as the auger 105 rotates, the sewage is discharged from the pump body 114 through the drain pipe 101. At the same time, the rotation of the auger 105 can drive the rotating rod 108 and the stirring blade to rotate, thereby mixing the sludge with the water, so as to effectively separate the water and dirt. At the same time, during the rotation of the stirring blade, the filter screen 107 can protect the rotation of the stirring blade to avoid interference with the stirring of the stirring blade, and the detachable filter screen 107 can also be easily cleaned.

[0039] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
