Description

Technical Field

[0001] This utility model relates to the field of sewage pump technology, and more specifically, to a sewage pump with anti-clogging function. Background Technology

[0002] A sewage pump is a type of pump where the pump and motor are integrated and simultaneously submerged in liquid. Compared to general horizontal or vertical sewage pumps, sewage pumps are more compact and occupy less space. Installation and maintenance are convenient; large sewage pumps are generally equipped with automatic coupling devices for automated installation, making installation and maintenance quite convenient. They also have a long continuous operating time. Because the pump and motor are coaxial, the shaft is short, and the rotating parts are lightweight, the load (radial) on the bearings is relatively small, resulting in a much longer lifespan than ordinary pumps. However, sewage generally contains various impurities, which can cause blockages when they enter the sewage pump.

[0003] A novel anti-clogging sewage pump is disclosed in utility model publication number CN221857135U, belonging to the field of sewage treatment technology. The novel anti-clogging sewage pump includes: a base; a motor is bolted to the upper side of the base; a self-priming water pump is bolted to the upper side of the base; a motor is connected to one side of the self-priming water pump; a water outlet pipe is fixed to the top of the self-priming water pump; an anti-clogging component is provided on one side of the self-priming water pump; and a water inlet pipe is provided on one side of the anti-clogging component. This utility model, by setting up two snap-fit ​​plates and inserting a filter frame, can effectively intercept impurities in sewage, ensuring that the discharged water will not clog the pump body due to larger impurities. Simultaneously, users can easily rotate the top plate connecting rod to open the top plate and remove the filter frame for cleaning or replacement, greatly reducing the difficulty and time of maintenance and cleaning, allowing users to conveniently perform maintenance in homes, commercial spaces, or industrial locations.

[0004] It should be noted that although this utility model can effectively prevent clogging, in sewage, if large soft impurities (such as plastic bags, tangled yarn, etc.) are encountered, the suction force generated by the motor at the inlet will cause these impurities to be sucked in and stick to the filter screen, which will also cause clogging. In severe cases, it may lead to motor overload and burnout. Therefore, an anti-clogging sewage pump that can target such impurities is designed. Utility Model Content

[0005] The purpose of this invention is to provide a sewage pump with anti-clogging function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-6 This embodiment provides a technical solution:

[0027] A sewage pump with anti-clogging function includes a pump body 1. The top of the pump body 1 is covered with a mesh cover 10 of the same size as its top surface. A funnel-shaped diversion plate 2 is integrally formed at the upper part of the pump body 1. A water inlet hole 21 is opened at the bottom of the diversion plate 2. An inner chamber 3 with an inner diameter equal to that of the water inlet hole 21 is provided at the center of the bottom of the diversion plate 2. A load-bearing plate 4 is provided at the center of the inner chamber 3. A circular turntable 41 is snapped onto the top of the load-bearing plate 4. A centering rod is fixed at the center of the top surface of the turntable 41, with its top end penetrating the center of the mesh cover 10 and extending to the outside. On the top surface of the centering column 6 and the turntable 41, there are symmetrically fixed debris removal columns 5 on both sides of the centering column 6. Several anti-corrosion wires 51 are fixed on the outer wall of the debris removal columns 5. A sweeper 7 with a length greater than or equal to the radius of the mesh cover 10 is horizontally installed on the top of the centering column 6. The first motor 31 is installed inside the inner chamber 3. The top end of the output shaft of the first motor 31 passes through the load-bearing plate 4 and is fixedly connected to the bottom of the turntable 41. Several booster pumps 8 are installed on the inner bottom surface of the pump body 1 on the outside of the inner chamber 3. The booster pumps 8 are connected to the inner chamber 3 through a pipe group 9.

[0028] In this embodiment, in order to perform preliminary filtration of impurities in sewage, the mesh cover 10 is fixedly connected to the top surface of the pump body 1 by bolts, and a sealing ring that is tightly attached to the outer wall of the hole opened in the center of the mesh cover 10 is attached to the inner wall of the hole.

[0029] Secondly, to ensure a leak-proof seal, the bottom of the inner chamber 3 is fixedly connected to the upper bottom surface of the pump body 1 by bolts. The upper bottom surface of the inner chamber 3 is fixed with a vertically upward support column by bolts, and the support column is fixedly connected to the bottom of the load-bearing plate 4 by bolts. A sealing ring is clamped and bonded between the outer wall of the load-bearing plate 4 and the inner wall of the inner chamber 3. Several openings are provided on the side wall of the inner chamber 3 above the load-bearing plate 4, which are equal in number and correspond one-to-one with the number of booster pumps 8.

[0030] In addition, to ensure stability, the central column 6 is welded and fixed to the top surface of the turntable 41. Since it needs to be replaced frequently, the impurity removal column 5 is inserted and fixed to the top surface of the turntable 41. In order to maximize the removal of suspended impurities in the sewage, the length of several anti-corrosion wires 51 on each impurity removal column 5 increases from bottom to top. The length of the anti-corrosion wire 51 is less than the distance between the diversion plate 2 and the central column 6 at its horizontal height.

[0031] Furthermore, in order to remove the impurities adsorbed on the upper surface of the mesh cover 10, the sweeper 7 includes a second motor 71 installed at the top of the centering column 6. The output shaft of the second motor 71 is connected to a chain 72 via a sprocket drive. A rotating broom 73 is fixed to the outside of the chain 72. The bottom surface of the rotating broom 73 is always in contact with the upper surface of the mesh cover 10, and the bottom surface of the rotating broom 73 rotates away from the centering column 6.

[0032] Specifically, in order to prevent the sweeper 7 from getting tangled and stuck, a cover 61 is integrally formed on the top surface of the central column 6 to surround the sweeper 7 on the other three sides except the bottom surface. The cover 61 does not contact the rotating broom 73, and the cover 61 does not contact the net cover 10.

[0033] Furthermore, in order to efficiently and quickly discharge sewage, the pipeline group 9 includes several inlet pipes 91 and several outlet pipes 92. The number of booster pumps 8, inlet pipes 91 and outlet pipes 92 are equal. The booster pumps 8 are fixed to the bottom surface of the pump body 1 by bolts. Each booster pump 8 has an inlet pipe 91 connected to its inlet port 81. The other end of the inlet pipe 91 is connected to the inner chamber 3. Each booster pump 8 has an outlet pipe 92 connected to its outlet port 82. Several outlet pipes 92 are connected to the same main outlet pipe that passes through one side wall of the pump body 1 and extends to the outside.

[0034] Similarly, to ensure the stability, robustness, and waterproofness of the equipment, the inner and outer walls of the pump body 1 are evenly coated with anti-corrosion paint, and the two symmetrical outer walls of the pump body 1 are integrally formed with hanging holes 11 for hoisting the whole unit.

[0035] When using the sewage pump with anti-clogging function of this utility model, the device is placed into the sewage through the hanging hole 11. After being powered on, the device starts to operate. The booster pump 8 works to draw the sewage into the upper mesh cover 10 and introduces the sewage into the inner chamber 3 through the diversion plate 2. At the same time, the impurity removal column 5 and the centering column 6, which are fixed on the load-bearing plate 4, start to rotate under the drive of the bottom motor to remove impurities, thereby removing large impurities in the sewage and impurities attached to the upper surface of the mesh cover 10. After that, the sewage is pressurized by four booster pumps 8 and then efficiently pumped out and discharged to the outside through the main outlet pipe.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to these embodiments without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of the utility model as claimed. The scope of protection of this utility model is defined by the appended claims and their equivalents.
