Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to a sewage pump with a filtering structure. Background Art

[0002] With the acceleration of urbanization and the continuous growth of industrial development, the problem of sewage treatment and discharge has become increasingly prominent. In the sewage treatment and discharge system, the sewage pump, as a key equipment, undertakes the important task of pumping sewage from a low place and discharging it to a high place or a distant place. The sewage pump is a pump product that combines a pump and a motor and works underwater at the same time. It has the advantages of being able to be placed in water, without the need to build a special pump room, and being able to be placed in a designed pool.

[0003] Existing sewage pumps usually have built-in filters to filter solid particles and impurities in sewage. However, when the sewage pump is in use, the sewage pump body will suck sewage into the sewage pump body through the water inlet, and then filter it through the filter. The filtered impurities will accumulate on the filter over a long period of time. Large impurities in the filtered impurities will cause more blockages, requiring staff to frequently clean the impurities on the filter, which greatly increases the workload of the staff. For this reason, we propose a sewage pump with a filtering structure. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a sewage pump with a filtering structure. Through the provided crushing component, larger impurities in sewage can be crushed, thereby reducing the number of times the filter screen is blocked, and at the same time reducing the number of times staff clean impurities on the filter screen and reducing the workload of staff.

[0022] Example:

[0023] See also Figure 1 - Figure 5 A sewage pump with a filtering structure comprises a sewage pump body 1, a water inlet 2 and a connecting pipe 3. A water inlet 2 is arranged on the right side of the sewage pump body 1, a filter screen is built in the water inlet 2, a connecting pipe 3 is connected to the right side of the water inlet 2 through a flange, a crushing component 4 is arranged on the right end surface of the water inlet 2, a limiting component 5 is arranged between the water inlet 2 and the connecting pipe 3, and the water inlet 2 is connected to the connecting pipe 3 through the limiting component 5.

[0024] By setting the crushing component 4, larger impurities in the sewage can be crushed, thereby reducing the number of times the filter screen is blocked, and at the same time reducing the number of times the staff cleans the impurities on the filter screen and reducing the workload of the staff. By setting the limiting component 5, the purpose of aligning the threads on the water inlet 2 and the connecting pipe 3 can be achieved, so that the staff can connect the water inlet 2 and the connecting pipe 3 by using the flange, effectively preventing the thread misalignment between the water inlet 2 and the connecting pipe 3 during installation, and improving the installation efficiency of the water inlet 2 and the connecting pipe 3.

[0025] In other embodiments, the crushing assembly 4 includes a movable groove 41 opened on the right end surface of the water inlet 2, a bracket 42 is provided on the inner wall of the water inlet 2, a bearing 43 is built into the right end surface of the bracket 42, a crushing blade 44 is fixedly connected to the bearing 43, and teeth 45 are provided on the outer wall of the crushing blade 44. A driving motor 46 is provided on the left side surface of the water inlet 2, and the output end of the driving motor 46 passes through the movable groove 41, and a gear 47 is provided on the output end, and the gear 47 is meshed with the teeth 45;

[0026] When in use, first start the drive motor 46 through the controller, so that the drive motor 46 drives the gear 47 to rotate. At this time, the teeth 45, driven by the gear 47, drive the crushing blade 44 to rotate on the bearing 43, so as to crush larger impurities in the sewage, thereby reducing the number of times the filter is blocked, and at the same time reducing the number of times the staff cleans the impurities on the filter, and reducing the workload of the staff. It is worth noting that the drive motor 46 has a built-in battery, and the drive motor 46 is connected to the controller through a wire. A groove for placing the controller is provided on the water inlet 2, which can facilitate the staff to operate the drive motor 46 through the controller to prevent the controller from being lost during use.

[0027] In other embodiments, a sealing ring is provided at the connection between the bracket 42 and the crushing blade 44. The crushing blade 44 is designed with double edges, which can increase the sealing performance of the connection between the bracket 42 and the crushing blade 44 and prevent sewage from entering the bracket 42 and damaging the bearing 43.

[0028] In other embodiments, the limiting assembly 5 includes two groups of positioning rods 51 symmetrically arranged on the right end surface of the water inlet 2, the connecting pipe 3 slides on the positioning rods 51, a movable bin 52 is arranged on the top surface of the water inlet 2, a guide rod 53 is arranged on the inner wall of the movable bin 52, a slider 54 slides on the guide rod 53, a spring 55 is wound on the surface of the movable bin 52 above the slider 54, a handle 56 is arranged on the left side of the slider 54, a limiting rod 57 is arranged on the right side of the slider 54, and a limiting groove 58 is provided on the surface of the positioning rod 51 corresponding to the bottom surface of the limiting rod 57;

[0029] When in use, first push the handle 56 toward the top of the movable bin 52. The handle 56 is designed in a mouth shape, and the surface of the handle 56 is provided with anti-skid patterns, which can facilitate the staff to operate the slider 54 through the handle 56 to prevent the hand from slipping, resulting in the need to re-operate the slider 54, so that the handle 56 drives the slider 54 to slide on the guide rod 53, and the slider 54 pushes the spring 55 to move toward the inner wall of the movable bin 52, and the spring 55 is deformed. While sliding, the slider 54 simultaneously drives the limit rod 57 to move, and then the connecting pipe 3 is put on the positioning rod 51. At this time, the limit rod 57 is aligned with the limit groove 58 in the positioning rod 51, and then the handle 56 is released, and the restoring force generated by the squeezing of the spring 55 is used to push the slider 54 to reset and slide on the guide rod 53, and the limit rod 57 passes through the limit groove 58. In other embodiments, the limit rod 57 is designed in a rectangular shape, and the limit groove 58 is provided as a through hole matching the limit rod 57. The limiting rod 57 and the limiting groove 58 are adapted to each other, so that the limiting rod 57 and the limiting groove 58 can fit together, thereby achieving the purpose of positioning the water inlet 2 and the connecting pipe 3, preventing the water inlet 2 and the connecting pipe 3 from shaking during installation, which causes the threaded holes to be misaligned, thereby achieving the purpose of aligning the threads on the water inlet 2 and the connecting pipe 3, so that the staff can connect the water inlet 2 and the connecting pipe 3 by using a flange, effectively preventing the threads on the water inlet 2 and the connecting pipe 3 from being misaligned during installation, and improving the installation efficiency of the water inlet 2 and the connecting pipe 3.
