[0002] Sewage pump is a kind of centrifugal impurity pump. Its main components include impeller and pressure chamber. It has many forms, including submersible type and dry type. Among them, the common dry sewage pumps are horizontal sewage pumps and vertical sewage pumps. These pumps are mainly used to transport urban sewage, feces or liquid media containing solid particles such as fibers and paper scraps.

[0003] But the following problems still exist:

[0004] However, since the transported medium may contain fibers that are easy to entangle or bunch, it is easy to cause blockage of the impeller and the water pressure chamber. The blockage of the impeller and the water pressure chamber will cause the pump to fail to work normally and may even burn the motor, which will have a serious impact on urban life and environmental protection.

[0005] Therefore, we propose a sewage pump with anti-clogging function to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 A sewage pump with anti-blocking function comprises a pump body 1, an impeller 2 and a driving shaft 3. A connecting plate 4 is fixedly connected to the bottom of the pump body 1, and the bottom surface of the connecting plate 4 is connected to an anti-blocking pipe 6. A fixing screw 5 is provided at the connection between the connecting plate 4 and the anti-blocking pipe 6, and an anti-blocking mechanism is provided inside the anti-blocking pipe 6.

[0024] It can be seen from the above structure that; by setting the pump body 1, impeller 2, drive shaft 3, connecting plate 4, anti-blocking pipe 6 and anti-blocking mechanism for use in combination, when the pump body 1 starts to be used, the bottom surface of the anti-blocking pipe 6 is connected to the water inlet pipe, and the sewage will enter the anti-blocking pipe 6 through the water inlet pipe, and then be crushed by the anti-blocking mechanism, and the fibers that are easy to be entangled or bunched will be cut and separated, and then discharged from the pump body 1 through the impeller 2, thereby preventing the impeller 2 from being blocked, and the structure is simple, easy to manufacture and install, and improves convenience of use.

[0025] Furthermore, the anti-blocking mechanism includes an anti-blocking shaft 10, and the side wall of the anti-blocking shaft 10 is fixedly connected with a plurality of groups of cross blade discs 11 distributed in a conical shape, annular grooves 14 are provided on the upper and lower sides of the cross blade disc 11, and a cross fixing ring 15 is rotatably connected to the inner wall of the annular groove 14, and the side wall of the cross fixing ring 15 is fixedly connected to the side wall of the anti-blocking tube 6, and the side wall of the anti-blocking shaft 10 located above the cross blade disc 11 is rotatably connected with a filter disc 12, and the side wall of the filter disc 12 is fixedly connected to the inner wall of the anti-blocking tube 6, and a power sleeve 7 is welded to the top surface of the anti-blocking shaft 10, and a power groove 8 is provided on the upper surface of the power sleeve 7, and a driving rod 9 is fixedly connected to the bottom surface of the driving shaft (3), and the side wall of the driving rod 9 is slidably connected to the side wall of the power groove 8; by arranging the anti-blocking tube 6, the anti-blocking shaft 10, the cross blade disc 11, the annular groove 14, the cross fixing ring 15, the side wall of the cross fixing ring 15 is fixedly connected to the side wall of the anti-blocking tube 6 The cross-shaped fixing ring 15, filter disc 12, power sleeve 7, power slot 8 and driving rod 9 are used together. When the pump body 1 starts to work, the rotating driving shaft 3 drives the power sleeve 7 to rotate through the driving rod 9, and then the anti-blocking shaft 10 starts to rotate, so that the cross blade disc 11 cuts and crushes the fibers that are easy to entangle or bunch in the sewage. The design of the conical cross blade disc 11 plays a role of layer-by-layer cutting to prevent the situation that the fibers are too large to be cut. The filter disc 12 will block the oversized fibers and make them fall to the cross blade disc 11 for further cutting, thereby improving the cutting efficiency. When installing the anti-blocking pipe 6, it is only necessary to slide the power slot 8 and the driving rod 9 together, and then fix the anti-blocking pipe 6 with the fixing screw 5. The installation is simple, easy to manufacture and convenient to use.

[0026] Furthermore, the side walls of the anti-blocking shaft 10 on both sides of the filter disc 12 are fixedly connected with anti-blocking brushes 13, and the brush parts of the anti-blocking brushes 13 are against the side walls of the filter disc 12; when the filter disc 12 filters fiber matter, the fiber matter remaining on the filter disc 12 will be brushed away by the anti-blocking brushes 13, preventing the fiber matter from sticking to the filter disc 12 and causing the filter disc 12 to be blocked, thereby improving the filtration efficiency.

[0027] Furthermore, the side wall of the cross blade disc 11 is fixedly connected with a reinforcing rib 16; by providing the reinforcing rib 16, the cross blade disc 11 is prevented from shaking when cutting fiber materials, thereby improving the stability of the cross blade disc 11 when cutting.

[0028] Furthermore, a cone head 17 is welded to the bottom surface of the anti-blocking shaft 10; by providing the cone head 17, the fiber material is prevented from being blocked by the bottom surface of the anti-blocking shaft 10 and unable to flow, thereby diverting the fiber material.

[0029] Furthermore, the bottom surface of the cross fixing ring 15 is fixedly connected with a slope block 18; due to the design of the slope block 18, the fibers in the sewage will slide through the cross fixing ring 15 through the slope block 18, thereby preventing the fibers from being blocked by the cross fixing ring 15 and then diverting the fibers.
