Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to an anti-blocking vertical water pump for cooling and cooling raw materials medicine. Background Art

[0002] When cooling and cooling raw materials medicine, a water pump is required to pump water for circulation cooling. A pump is a pump that uses the force generated by the blades of a rotating impeller to convey liquid along the axial direction, and there are several types such as vertical, horizontal, inclined and tubular. The existing vertical water pumps have certain defects. When impurities are blocked on the surface of the trash screen, the impurities at the trash screen cannot be processed, and the water pump is prone to dry running, reducing the pumping efficiency. In the initial stage of the water pump operation, the method of cleaning each time a blockage occurs and ensuring that it does not stay overnight each time it is cleaned is used. Although this avoids shutdown, frequent disassembly of the pump body will cause serious wear of components such as the pump mouth ring, and each cleaning of the blockage will consume a lot of manpower and material resources. Therefore, a vertical water pump for cooling and cooling raw materials medicine is needed to improve the above problems. Summary of the Invention

[0003] The technical problem solved by the utility model: Provide an anti-blocking vertical water pump for cooling and cooling raw materials medicine.

[0004] In order to solve the above technical problems, the technical scheme adopted by the utility model is as follows:

The filtering device includes a filter screen plate, a metal mesh cover and a cover body arranged outside the metal mesh cover. The cleaning device includes a hydraulic cylinder fixed on the metal mesh cover and driving the cover body to move up and down, an upper brush plate and a side brush plate connected to a rotating shaft.

[0006] Preferably, a filter screen plate and a pump body impeller shaft docking groove are arranged at the bottom of the pump body, and the pump body impeller shaft docking groove is arranged in the middle of the filter screen plate.

[0007] Preferably, a hydraulic cylinder, a conical plate and a hydraulic pump connected to the hydraulic cylinder are arranged at the bottom of the cover body.

[0008] Preferably, the rotating shaft is correspondingly arranged below the pump body impeller shaft docking groove, the outer diameter of the rotating shaft corresponds to the inner diameter of the pump body impeller shaft docking groove, and the bottom of the rotating shaft is movably connected to the conical plate.

[0010] Preferably, a plurality of through grooves are arranged on the surface of the cover body.

[0011] Preferably, a rubber wheel is arranged inside the through slot, and a switch plate is arranged at the lower end of the rubber wheel.

[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0013] (1) The utility model drives the hydraulic cylinder to contract through the hydraulic pump, so that the cover body moves upward to cover the metal mesh cover.

DETAILED DESCRIPTION

[0019] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] like Figures 1-3 As shown, the utility model is an anti-clogging vertical water pump for cooling raw materials, including a pump body 1, a metal mesh cover 2, an upper brush plate 3, a rubber runner 4, a hydraulic cylinder 5, a switch plate 6, a rotating shaft 7, a hydraulic pump 8, a conical plate 9, a cover body 10, a through groove 11, a side brush plate 12, a filter mesh plate 13, and a pump body fan blade shaft docking groove 14.

[0021] At the lower end of the pump body 1, there are a metal mesh cover 2, an upper brush plate 3, a rubber runner 4, a hydraulic cylinder 5, a switch plate 6, a rotating shaft 7, a hydraulic pump 8, a conical plate 9, a cover body 10, a through groove 11, a side brush plate 12, a filter screen plate 13, and a pump body fan blade shaft docking groove 14. The cover body 10 is arranged outside the metal mesh cover 2. When the cover body 10 moves upward, it covers the metal mesh cover 2, facilitating subsequent cleaning of the sediment.

[0022] At the bottom of the pump body 1, there are a filter screen plate 13 and a pump body fan blade shaft docking groove 14. The pump body fan blade shaft docking groove 14 is arranged in the middle of the filter screen plate 13. The rotating shaft 7 is correspondingly arranged directly below the pump body fan blade shaft docking groove 14. The outer diameter of the rotating shaft 7 corresponds to the inner diameter of the pump body fan blade shaft docking groove 14. The bottom of the rotating shaft 7 is movably connected to the conical plate 9. Specifically, a bearing is arranged on the conical plate 9, and the bottom end of the rotating shaft 7 is connected to the bearing.

[0023] Horizontally arranged at the upper end of the rotating shaft 7 is an upper brush plate 3. Radially arranged at both ends of the upper brush plate 3 are side brush plates 12. When the rotating shaft 7 works, the brush tip of the upper brush plate 3 contacts the lower wall of the filter screen plate 13, and the brush tip of the side brush plate 12 contacts the side wall of the metal mesh cover 2.

[0024] When the top end of the rotating shaft 7 is inserted into the pump body fan blade shaft docking groove 14, the pump body 1 is started, thereby driving the upper brush plate 3 and the side brush plate 12 on the rotating shaft 7 to rotate, cleaning the lower wall of the filter screen plate 13 and the side wall of the metal mesh cover 2.

[0025] At the bottom of the cover body 10, there are a hydraulic cylinder 5, a conical plate 9, and a hydraulic pump 8. The upper end of the hydraulic cylinder 5 is connected to the metal mesh cover 2, and the lower end is connected to the cover body 10. They are symmetrically arranged below the metal mesh cover 2 and are used to drive the cover body 10 to move up and down. The hydraulic pump 8 is arranged inside the conical plate 9 and is in transmission connection with the hydraulic cylinder 5. The conical plate 9 slopes downward from the middle to the periphery, enabling the sediment falling onto the conical plate 9 to be discharged from the through groove 11 at the bottom.

[0026] Several through grooves 11 are arranged on the surface of the cover body 10. Inside each through groove 11, there is a rubber runner 4, and a switch plate 6 is arranged at the lower end of the rubber runner 4. When the rubber runner 4 contacts and rotates with the metal mesh cover 2, it drives the switch plate 6 to rotate. When the cover body 10 moves upward to cover the metal mesh cover 2, the rubber runner 4 makes frictional contact with the metal mesh cover 2, and the rubber runner 4 rotates, thereby driving the switch plate 6 to rotate outward and be in an open state. At the same time, during the upward movement of the cover body 10, the sediment on the outer wall of the metal mesh cover 2 will be scraped off. The switch plate 6 is made of a lightweight material such as plastic.

[0027] Working principle of the utility model: During use, the hydraulic pump 8 drives the hydraulic cylinder 5 to contract, so that the cover body 10 moves upward to cover the wire mesh cover 2. The wire mesh cover 2 contacts the rubber runner 4, driving the rubber runner 4 to rotate, thereby driving the switch plate 6 to open. At the same time, the sediment on the outer wall of the wire mesh cover 2 will be scraped off. The upper end of the rotating shaft 7 is inserted into the pump body fan blade shaft docking groove 14, and the pump body 1 is started, driving the upper brush plate 3 and the side brush plate 12 on the rotating shaft 7 to rotate, cleaning the lower wall of the filter screen plate 13 and the side wall of the wire mesh cover 2. The sediment falling on the conical plate 9 is discharged from the through groove 11 at the bottom; after the cleaning is completed, the hydraulic pump 8 drives the hydraulic cylinder 5 to extend, the upper end of the rotating shaft 7 moves away from the pump body fan blade shaft docking groove 14, and the pump body 1 is closed.

[0028] The above are only the preferred embodiments of the utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
