Abstract
Description
Technical Field
[0001] This invention relates to the field of material conveying technology, specifically to an air-powered lift pump. Background Technology
[0002] Pneumatic booster pumps are devices that use compressed air energy to transport slurry or powder materials, and are widely used in industries such as mining, metallurgy, building materials, and chemicals. During long-term operation, the transported materials (especially high-concentration, highly viscous, or easily caking materials) tend to deposit, adhere, and harden on the inner wall of the booster pump, forming severe scale or caking layers. This not only significantly reduces the effective volume of the pump and lowers the conveying efficiency, but also alters the flow field within the pump, leading to increased energy consumption and potentially causing blockages, resulting in unplanned downtime and severely impacting the continuity and stability of production. Currently, the cleaning and maintenance of the inner wall of pneumatic booster pumps mainly relies on two methods: one is fixed cleaning, such as setting fixed flushing water or air jets on the pump body. This method has a limited cleaning range, many cleaning dead zones, and is ineffective at removing hardened scale; the other is manual cleaning, which requires stopping the equipment, opening the pump body, and having operators enter the interior to clean the scale. The latter is not only labor-intensive, with harsh working environments and safety hazards, but also has a long cleaning cycle, leading to a significant reduction in the effective operating rate of the equipment.

[0012] This invention provides an air-powered lift pump, which has the following beneficial effects: 1. When cleaning is required, the cleaning arm can extend into the pump body, and the nozzle at its end can spray high-pressure gas to directly impact the inner wall, effectively removing adhering or caked materials. Driven by a third motor, the cleaning arm can move up and down along the guide rail; driven by a second motor, the cleaning arm can drive the entire nozzle to rotate; driven by a fourth motor, the radial extension and retraction of the nozzle push column can be controlled to extend or retract the nozzle. The combination of these three dimensions of movement allows the high-pressure airflow to cover most of the inner wall of the pump body, cleaning without dead angles, and the efficiency and thoroughness far exceed traditional fixed cleaning or manual cleaning methods.
[0013] 2. Material contamination and interference are avoided, ensuring continuous conveying: The first and second top plugs are connected by a connecting arm and can be raised and lowered by a hydraulic rod, while the overall rotation is controlled by a first motor. Normal operating state: The second top plug descends, sealing the top opening of the lifting pump body to ensure a seal. Material enters through the feed pipe, and gas enters through the air inlet pipe for normal pneumatic material lifting and conveying. Cleaning operating state: First, the hydraulic rod raises the second top plug. Then, the first motor drives the entire upper mechanism to rotate, rotating the first top plug with the cleaning mechanism to above the top opening of the pump body, and then lowering the first top plug to seal it. Subsequently, the cleaning arm lowers from the center of the first top plug to begin the cleaning operation. This "dual top plug rotation switching" design completely isolates the cleaning operation from the material conveying operation. The cleaning mechanism does not occupy the internal conveying space of the pump body. Attached Figure Description

The output end of the second motor 18 drives the first gear 19 to rotate, so that the first gear 19 drives the second gear 21 to rotate, so that the second gear 21 drives the slider 23 to slide inside the annular cavity 24.
[0021] The top of the fixed box 40 is fixedly connected to a fourth motor 41, the output end of the fourth motor 41 extends into the interior of the fixed box 40, the top end of the main rod 30 extends into the interior of the fixed box 40, and the output end of the fourth motor 41 and the outer side of the main rod 30 are both fixedly fitted with meshing third gears 42.

When the extension end of the hydraulic rod 8 pushes the connecting arm 9 to drive the second top plug 11 and the first top plug 10, as well as the connecting box 16 and the guide rail 36 to move up and down, the guide rail 36 drives the guide plate 51 to slide along the inside of the guide post 13.
[0024] Example 2 Please see Figures 1 to 9The present invention provides a technical solution: a material pipe 47 is installed on the outside of the lifting pump body 2, an air inlet pipe 48 is installed on the outside of the lifting pump body 2 and in front of the material pipe 47, an exhaust pipe 49 is installed on the outside of the lifting pump body 2 and behind the material pipe 47, a conveying pipe 50 is fixedly connected to the bottom of the lifting pump body 2, a first motor 5 is fixedly connected to the bottom of the support base 4 through a bracket, the output end of the first motor 5 is fixedly connected to the bottom of the rotating column 6, and exhaust gas is discharged through the exhaust pipe 49.
[0025] In summary, when this pneumatic lift pump is in use, material is injected into the lift pump body 2 through the material pipe 47, and compressed gas is input into the lift pump body 2 through the air inlet pipe 48. The compressed gas carries the material through the conveying pipe 50 and is then transported out to the subsequent processing equipment. When cleaning of the inner wall of the lifting pump body 2 is required, the telescopic end of the hydraulic rod 8 pushes the connecting arm 9 to move the second top plug 11 and the first top plug 10 upwards, so that the bottom end of the second top plug 11 moves out of the opening at the top of the lifting pump body 2. Then, the output end of the first motor 5 drives the rotating column 6, the hydraulic rod 8, the connecting arm 9, the first top plug 10, and the second top plug 11 to rotate, so that the fixed rod 7 drives the guide column 13 and the top plate 14 to rotate, so that the top plate 14 moves circumferentially inside the three guide frames 15, so that the first top plug 11 moves out of the opening at the top of the lifting pump body 2. The hydraulic rod 8 drives the connecting box 16, guide rail 36, and rotating rod 17 to rotate to the top of the lifting pump body 2. Then, the telescopic end of the hydraulic rod 8 drives the connecting arm 9, the first top plug 10, and the second top plug 11 to move downward, so that the bottom end of the first top plug 10 is inserted into the opening at the top of the lifting pump body 2. Then, the output end of the third motor 37 drives the threaded shaft 38 to rotate, so that the threaded shaft 38 drives the drive block 39 to move downward, so that the drive block 39 drives the fixed box 40 and the rotating rod 17 to move downward, so that the rotating rod 17 pushes the bottom box 25 downward. The movement causes the base box 25 to move downwards, driving the drive box 26. As the drive box 26 moves, the output of the fourth motor 41 drives the main rod 30 to rotate via two third gears 42. The main rod 30 drives the bevel gear ring 32 to rotate, which in turn drives four bevel gears 31 to rotate the threaded rod 27. The threaded rod 27 then drives the push column 28 and the nozzle 29 to extend. Air is drawn in and compressed by the pressurized air pump 44, and the gas is input to the first rotary joint 43 through the second rotary joint 43 and the main rod 30. The head 33 is connected to the main pipe 34 and the hose 35. The hose 35 leads to the nozzle 29. The nozzle 29 sprays the contents onto the inner wall of the pump body 2. The output of the second motor 18 drives the first gear 19 to rotate, which in turn drives the second gear 21 to rotate. The second gear 21 drives the rotating rod 17 to rotate through the guide block 20 and the guide groove 22. The rotating rod 17 drives the base box 25, the drive box 26, and the nozzle 29 to rotate in a circular motion, thereby cleaning the inner wall of the pump body 2. After cleaning the inner wall of the booster pump body 2, the output end of the third motor 37 drives the threaded shaft 38 to rotate in a reset manner. This causes the threaded shaft 38 to drive the drive block 39 to move upward, which in turn drives the fixed box 40 and the rotating rod 17 to move upward. The rotating rod 17 then pushes the bottom box 25 upward, which in turn drives the drive box 26 upward. As the drive box 26 moves, the output end of the fourth motor 41 drives the main rod 30 to rotate in a reset manner through two third gears 42. This causes the main rod 30 to drive the bevel gear ring 32 to rotate in a reset manner, which in turn drives the four bevel gears 31 to drive the threaded rod 27 to rotate in a reset manner. This causes the threaded rod 27 to drive the push column 28 and the nozzle 29 to retract to their initial positions. Then, the hydraulic rod 8... The telescopic end of the hydraulic rod 8 pushes the connecting arm 9 to move the second top plug 11 and the first top plug 10 upward, so that the bottom ends of the first top plug 10, the bottom box 25 and the drive box 26 move out of the top opening of the lifting pump body 2. Then, the output end of the first motor 5 drives the rotating column 6, the hydraulic rod 8, the connecting arm 9 and the first top plug 10 and the second top plug 11 to rotate, so that the fixed rod 7 drives the guide column 13 and the top plate 14 to rotate, so that the top plate 14 moves circumferentially inside the three guide frames 15, so that the second top plug 11 rotates to the top of the lifting pump body 2. Then, the telescopic end of the hydraulic rod 8 drives the connecting arm 9 and the first top plug 10 and the second top plug 11 to move downward, so that the bottom end of the second top plug 11 is inserted into the top opening of the lifting pump body 2.
