Description

Technical Field

[0001] The present application relates to the technical field of sewage pumps, and in particular to a sewage pump with a filtering function. Background Art

[0002] Sewage pumps are also called sewage pumps. As key equipment for environmental protection and sewage treatment, sewage pumps play a very important role in municipal engineering, industry, water conservancy construction and other industries. Sewage pumps are generally installed at the bottom of the water to discharge sewage from sewage pools. When sewage pumps are working, due to the presence of complex debris in sewage, such as plastic bags, plastic fragments and large impurities, when sewage pumps transport sewage, the debris in the sewage will flow into the pump body of the sewage pump, and then the debris will affect the impeller in the pump body, reducing the transportation efficiency of the sewage pump or causing damage to the parts in the pump body. Utility Model Content

[0003] The utility model aims to provide a sewage pump with a filtering function in view of the defects and shortcomings of the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] It includes a pump body and a driving motor located above the pump body. The lower end of the pump body is provided with a water inlet. A bracket is vertically arranged around the water inlet. The lower end of the water inlet is provided with a conical filter screen. The tip of the middle part of the conical filter screen is arranged downward.

[0006] Preferably, a waste frame is provided below the conical filter screen, the upper end of the waste frame is sleeved and installed on the peripheral side of the lower end of the water inlet, the lower end of the waste frame has a feed port, the feed port corresponds to the tip of the conical filter screen, and the waste frame has a cavity for storing debris.

[0007] Preferably, the waste frame comprises a connecting ring and a receiving ring, the receiving ring is placed horizontally and the outer peripheral side is arranged at the lower end of the connecting ring.

[0008] Preferably, a mounting ring is provided at the upper end of the conical filter screen, the mounting ring is inserted into the water inlet, a plurality of fixing blocks are evenly arranged on the outer circumference of the mounting ring, and a ring groove for the fixing blocks to be clamped and fixed is circumferentially opened on the inner circumference of the water inlet.

[0009] Preferably, a plurality of mounting columns are evenly arranged on the inner side wall of the upper end of the connecting ring, and a plurality of assembly grooves for inserting and installing the mounting columns are evenly opened on the outer peripheral side of the water inlet.

[0010] Preferably, the assembly groove comprises a sliding groove and a fixed groove, the sliding groove is vertically arranged, the fixed groove is circumferentially arranged, and the upper end of the sliding groove is connected to one end of the fixed groove.

[0011] Preferably, the pump body is provided with guiding inclined surfaces on both sides of the lower end of the sliding groove.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. When the sewage pump needs to transport sewage, first install the conical filter at the lower end of the water inlet, then install the waste frame at the outer peripheral side of the water inlet, and then drive the motor to drive the impeller in the pump body to rotate, so as to extract the sewage. When there are debris in the sewage, the debris will flow into the water inlet with the sewage, but the debris will be blocked by the conical filter, so that the debris will not enter the pump body, thereby not affecting the transportation efficiency and service life of the pump body. Since the conical filter is placed downward, the debris will move outward under the inclined surface of the conical filter. When the debris moves to the edge of the conical filter, it will fall into the waste frame, so that the debris will not contact the conical filter again, so that the amount of water entering the conical filter remains unchanged;

[0014] 2. When installing the conical filter, insert the mounting ring on the upper end of the conical filter into the water inlet until the upper end of the conical filter abuts against the lower end of the water inlet, and the fixing block on the outer circumference of the mounting ring is clamped and fixed to the ring groove, thereby fixing the conical filter at the lower end of the water inlet, which improves the convenience of installing the conical filter;

[0015] 3. When installing the waste frame, place the upper end of the waste frame close to the lower end of the water inlet, and then the installation column of the waste frame slides into the sliding groove under the action of the guiding slope until the installation column abuts against the upper end of the sliding groove. Then, the waste frame is rotated so that the installation column is slidably installed in the fixed groove, thereby installing the waste frame at the lower end of the water inlet, which improves the convenience of installing the waste frame.

[0023] Reference Figure 2 and Figure 3 A conical filter screen 7 is placed at the lower end of the water inlet 3. The vertical section of the conical filter screen 7 is in a "V" shape. A mounting ring 8 is integrally provided on the inner circumference of the upper end of the conical filter screen 7. Four fixing blocks 9 are evenly integrally provided on the outer circumference of the mounting ring 8. The fixing blocks 9 are hemispherical. An annular groove 10 for the fixing blocks 9 to be clamped and fixed is provided in the circumferential direction of the inner circumference of the water inlet 3. When installing the conical filter screen 7, the mounting ring 8 at the upper end of the conical filter screen 7 is inserted into the water inlet 3 until the upper end of the conical filter screen 7 and the lower end of the water inlet 3 are in contact with each other, and the fixing blocks 9 on the outer circumference of the mounting ring 8 are clamped and fixed to the annular groove 10, thereby installing and fixing the conical filter screen 7 at the lower end of the water inlet 3.

[0024] A waste frame 11 is sleeved and fixed on the outer peripheral side of the lower end of the water inlet 3, and the waste frame 11 includes a connecting ring 12 and a receiving ring 13. The connecting ring 12 is placed vertically, and the receiving ring 13 is placed horizontally. The receiving ring 13 has a cavity 14 for storing debris. The upper end of the connecting ring 12 is sleeved on the outer peripheral side of the lower end of the water inlet 3, and the outer peripheral side of the receiving ring 13 is integrally arranged at the lower end of the connecting ring 12. The vertical section of the waste frame 11 is two symmetrical "J" shapes, and six mounting columns 15 are evenly and integrally arranged on the inner side wall of the upper end of the connecting ring 12. Six assembly grooves 16 are evenly opened on the outer peripheral side of the water inlet 3. The assembly groove 16 includes a sliding groove 17 and a fixed groove 18.
