Detailed Description

For further explanation of the various embodiments, the drawings which form a part of the disclosure and which are incorporated in and constitute a part of this specification, illustrate embodiments and, together with the description, serve to explain the principles of operation of the embodiments, and to enable others of ordinary skill in the art to understand the various embodiments and advantages of the utility model, and, by reference to these figures, reference is made to the accompanying drawings, which are not to scale and wherein like reference numerals generally refer to like elements.

According to an embodiment of the present invention, there is provided a sewage pump preventing backflow of foreign substances.

The first embodiment is as follows:

as shown in fig. 1-2, a sewage pump for preventing debris from flowing back comprises a motor set 1 and a vortex chamber 2 installed at the bottom of the motor set 1, wherein a water inlet pipe 3 is fixedly connected to the bottom of the vortex chamber 2, the middle part of the water inlet pipe 3 is rotatably connected with an annular block 4, a filter screen 5 is installed in the upper part of the water inlet pipe 3, a brush rod 6 is fixedly connected in the annular block 4, a driving motor 7 is installed on the outer wall on the right side of the upper part of the water inlet pipe 3 (the driving motor 7 is a waterproof motor, which is a general device in the market), a gear 8 is fixedly connected to the output end of the driving motor 7, a gear groove 9 is formed in the outer wall of the annular block 4, and the gear groove 9 is meshed with the gear 8;

example two:

the left end of the vortex chamber 2 is provided with a water outlet;

an impeller 10 is arranged in the vortex chamber 2, and a water inlet of the impeller 10 is communicated with the water inlet pipe 3;

smooth sealing gaskets are respectively attached to the upper annular wall and the lower annular wall of the annular block 4, so that the phenomenon that water leaks from a gap between the annular block 4 and the water inlet pipe 3 in the rotating process of the annular block 4 is avoided;

a bracket 11 is arranged on the outer wall of the lower part of the water inlet pipe 3;

the working principle of the utility model is as follows:

when sewage enters from the water inlet pipe 3, solid particles and fibrous matters in the sewage are intercepted by the filter screen 5, the filtered sewage enters the vortex chamber 2 from the water inlet of the impeller 10 and then is discharged from the water outlet of the vortex chamber 2, when the filter screen 5 is blocked, the driving motor 7 is started to control the gear 8 to rotate, then the gear 8 drives the annular block 4 to rotate through the gear groove 9, then the annular block 4 drives the brush rod 6 to rotate, and then the brush rod 6 brushes the solid particles and the fibrous matters intercepted on the filter screen 5, so that the smoothness of the filter screen 5 is ensured;

consequently this practicality sets up filter screen 5 in inlet tube 3, prevents that solid particle and fibre thing in the sewage from getting into the water inlet of impeller 10, avoids blockking up impeller 10's water inlet, and when filter screen 5 is blockked up by solid particle and fibre thing, restart driving motor 7 drives brush pole 6 rotatory, and solid particle and fibre thing on the filter screen 5 that falls are brushed, avoid filter screen 5 to block up, make the sewage pump can not take place to block up like this.
