Description

Technical Field

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

[0002] Sewage pumps, with their advantages of compact structure, small footprint, convenient installation and maintenance, low vibration and noise, and no pollution, play an increasingly important role in industrial production, construction site drainage, and the transportation of domestic sewage and industrial wastewater. However, clogging during sewage transportation remains a core technical challenge affecting work efficiency, equipment lifespan, and even normal operation.

[0003] A common method is to install a filter screen at the inlet or inside the pump to intercept large particles of debris. However, the filter screen itself is easily clogged by impurities, and it can only remove loose deposits on the surface of the screen. It is not effective at removing stubborn blockages embedded inside the mesh, and the problem of filter clogging is not fundamentally solved. Frequent shutdowns for manual cleaning are still required, which seriously affects the continuous working efficiency of the sewage pump. If it is not cleaned in time, it will seriously affect the water intake efficiency and also lead to a decline in pump performance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an anti-clogging sewage pump that facilitates the discharge of filter residue, reduces clogging, and thus improves conveying efficiency.

[0005] This utility model provides an anti-clogging sewage pump, including a base, a pump motor, a rotary motor, a filter screen, a sewage guide plate, and a sewage outlet. The base has a cavity and is equipped with an inlet, an outlet, and a sewage outlet communicating with the cavity. The pump motor is mounted on the base, with its drive end extending into the cavity to drive the water flow within the cavity towards the outlet. The filter screen and the sewage guide plate are both located within the base. The filter screen inlet communicates with the inlet, and the filter screen is positioned above the sewage guide plate. The sewage guide plate is inclined towards the sewage outlet, and its lower end communicates with the sewage outlet. The rotary motor is fixed to the base, and its drive end is fixed to the filter screen. When the rotary motor operates, it can invert the filter screen, aligning the filter screen inlet with the upper end of the sewage guide plate.

[0006] Compared with existing technologies, this application has the following advantages: When needed, a sewage pipe can be connected to the inlet. After the sewage is filtered through the filter screen, it flows into the cavity inside the base, and the filtered sewage is discharged to the outlet by a pump motor. When there is a lot of filter residue in the filter screen, affecting the sewage discharge efficiency, the filter screen is inverted by rotating the motor, so that the inlet of the filter screen is aligned with the upper end of the sewage discharge guide plate. The filter residue is poured into the sewage discharge guide plate by gravity and discharged to the sewage outlet through the sewage discharge guide plate. This application facilitates the discharge of filter residue, reduces the probability of clogging, and thus improves the conveying efficiency.

[0007] In one possible implementation, the base includes a placement platform and a boss integrally formed on the rear side of the placement platform, the boss being higher than the placement platform; the pump motor and the water outlet are both mounted on the placement platform; the rotating motor is fixed on the rear side wall of the boss; the drain outlet is located on the side wall of the boss; the filter screen and the drain guide plate are both located inside the boss.

[0008] Compared with existing technologies, the above technical solution can ensure that the filter screen has enough room to rotate in the cavity and provide enough guiding space for the sewage guide plate to guide the filter residue to the sewage outlet.

[0009] In one possible implementation, the boss includes a boss body and a cover; a rotating motor is located on the rear side wall of the boss body, and a drain outlet is located on the side wall of the boss body; a filter screen and a drain guide plate are both located inside the boss body; the cover is detachably connected to the upper end of the boss body.

[0010] Compared with existing technologies, the above-mentioned technical solution can facilitate the disassembly of the cover and cleaning of the filter screen or the filter guide plate if the sewage discharge efficiency is poor after long-term use, thus reducing clogging and improving the conveying efficiency.

[0011] In one possible implementation, a vibration motor is also included, and a mounting groove is provided on the bottom surface of the base, in which the vibration motor is fixed.

[0012] Compared with existing technologies, the above technical solution can cause the entire base to vibrate after the filter screen is inverted, thereby causing the filter screen to vibrate as well. This facilitates the removal of residual filter material inside the filter screen. The mounting groove ensures that the vibration motor can work stably and is not easily exposed to the outside environment, thus extending its service life and ensuring long-term use. This indirectly reduces clogging and improves conveying efficiency.

[0013] In one possible implementation, a cover plate is also included, which covers the mounting groove opening.

[0014] Compared with existing technologies, the above technical solution can protect the vibration motor, extend its service life, ensure long-term use, indirectly reduce blockage, and thus improve conveying efficiency.

[0015] In one possible implementation, a limiting plate is also included, which is fixed to the side wall of the filter screen and the upper end of the limiting plate protrudes from the upper end of the filter screen. When the inlet of the filter screen is aligned with the upper end of the drain guide plate, the limiting plate abuts against the drain guide plate.

[0016] Compared with existing technologies, the above technical solution can prevent the filter screen from rotating too much when it is inverted, and the limiting plate itself can also guide the filter residue, ensuring that the filter residue can be accurately poured into the sewage discharge guide plate.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] As attached Figure 1 This embodiment discloses an anti-clogging sewage pump, including a base 1, a pump motor 2, a rotary motor 3, a filter screen 4, and a sewage guide plate 5; as shown in the attached figure. Figure 2 and attached Figure 3 As shown, the base 1 has a cavity, and the base 1 is equipped with an inlet 11, an outlet 12, and a drain outlet 13 that communicate with the cavity; the pump motor 2 is mounted on the base 1, and its drive end extends into the cavity to drive the water flow in the cavity towards the outlet 12; the filter screen 4 and the drain guide plate 5 are both mounted inside the base 1, the inlet of the filter screen 4 communicates with the inlet 11, and the filter screen 4 is located above the drain guide plate 5; the drain guide plate 5 is inclined toward the drain outlet 13, and its lower end communicates with the drain outlet 13; the rotating motor 3 is fixed on the base 1, and its drive end is fixed to the filter screen 4. When the rotating motor 3 works, it can drive the filter screen 4 to invert, so that the inlet of the filter screen 4 is aligned with the upper end of the drain guide plate 5. (See attached diagram) Figure 2 As shown, the base 1 includes a placement platform 1.1 and a boss 1.2 integrally formed on the rear side of the placement platform 1.1, the boss 1.2 being higher than the placement platform 1.1; the pump motor 2 and the water outlet 12 are both mounted on the placement platform 1.1; the rotating motor 3 is fixed on the rear side wall of the boss 1.2; the drain outlet 13 is located on the right side wall of the boss 1.2; the filter screen 4 and the drain guide plate 5 are both located inside the boss 1.2. The boss 1.2 includes a boss body 1.21 and a cover 1.22; the rotating motor 3 is located on the rear side wall of the boss body 1.21, the drain outlet 13 is located on the side wall of the boss body 1.21; the filter screen 4 and the drain guide plate 5 are both located inside the boss body 1.21; the cover 1.22 is detachably connected to the upper end of the boss body 1.21.

[0028] Specifically, in this embodiment, as shown in the appendix Figure 3 As shown, the drive end of the pump motor 2 is equipped with blades to agitate the water flow towards the outlet. Figure 3To illustrate the cavity structure, the blades have been removed, and the blades on the drive end of the pump motor 2 are existing technology and not the focus of this application. Therefore, those skilled in the art can fully understand and implement the above solution. The cover 1.22 and the upper end of the boss 1.21 can be detachably connected by a snap-fit ​​structure using existing technology. The boss 1.2 is higher than the placement platform 1.1, ensuring that the filter screen 4 has sufficient rotation space within the cavity and providing sufficient guiding space for the sewage guide plate 5 to guide the filter residue to the sewage outlet 13. After long-term use, if the sewage discharge efficiency is poor, the cover 1.22 can be easily disassembled to clean the filter residue on the filter screen 4 or the sewage guide plate 5. When needed, a sewage pipe can be connected to the inlet 11. The sewage flows into the cavity inside the base 1 after being filtered by the filter screen 4, and the filtered sewage is discharged to the outlet 12 by the pump motor 2. When there is a lot of filter residue inside the filter screen 4, which affects the sewage discharge efficiency, the filter screen 4 is inverted by rotating the motor 3, so that the inlet of the filter screen 4 is aligned with the upper end of the sewage discharge guide plate 5. The filter residue is poured into the sewage discharge guide plate 5 by gravity and discharged to the sewage discharge port 13 through the sewage discharge guide plate 5. This embodiment facilitates the discharge of filter residue, reduces the probability of blockage, and thus improves the conveying efficiency.

[0029] As attached Figure 4 As shown, in some embodiments, a vibration motor 6 is also included. A mounting groove 14 is provided on the bottom surface of the base 1, and the vibration motor 6 is fixed in the mounting groove 14. In this embodiment, the groove wall of the mounting groove 14 is tightly fitted with the vibration motor 6, allowing the vibration motor 6 to be inserted into the mounting groove 14. Simultaneously, the vibration of the vibration motor 6 can effectively drive the entire base 1 to vibrate, thereby causing the filter screen 4 to vibrate as well. This facilitates the vibration and discharge of residual filter material inside the filter screen 4. The mounting groove 14 ensures that the vibration motor 6 can operate stably, is less likely to come into contact with the outside environment, extends its service life, ensures long-term use, indirectly reduces clogging, and thus improves conveying efficiency.

[0030] As attached Figure 2 As shown, in some embodiments, a cover plate 7 is also included, which covers the opening of the mounting groove 14. The cover plate 7 can be snapped into the opening of the mounting groove 14 using a snap-fit ​​structure in the prior art, or it can be directly fixed to the opening of the mounting groove 14 using screws or other existing technologies. The cover plate 7 can isolate the vibrating motor 6 from the outside, prevent wear on the vibrating motor 6 during vibration, extend its service life, ensure long-term use, indirectly reduce blockage, and thus improve conveying efficiency.

[0031] As attached Figure 2As shown, in some embodiments, a limiting plate 8 is also included. The limiting plate 8 is fixed to the side wall of the filter screen 4, and the upper end of the limiting plate 8 protrudes from the upper end of the filter screen 4. When the inlet of the filter screen 4 is aligned with the upper end of the drain guide plate 5, the limiting plate 8 abuts against the drain guide plate 5. The limiting plate 8 has a cuboid structure and is fixed to the right side wall of the filter screen 4. When the filter screen 4 is inverted, it prevents excessive rotation, and the limiting plate 8 itself can also guide the filter residue, ensuring that the filter residue can be accurately poured into the drain guide plate 5.
