Description

Technical Field

[0001] This utility model relates to the field of piston pump technology, specifically a low-noise rotary piston pump. Background Technology

[0002] A rotary piston pump is a type of positive displacement pump that changes the working volume through the relative motion between the rotor and the pump body, thereby increasing the energy of the liquid. On the side of the rotor within the pump body that contacts the liquid, energy is directly applied to the liquid in the form of static pressure, and the rotating rotor forces the liquid out, while a low-pressure space is created on the other side, allowing for continuous liquid intake.

[0003] According to Chinese Patent Publication No. CN 219570324 U, a corrosion-resistant and durable ceramic piston pump is disclosed. The device includes a mounting plate, an electric actuator mounted on the top of the mounting plate, and a rotary piston pump. A liquid outlet cylinder and a liquid inlet cylinder are respectively arranged on the side of the rotary piston pump. A filter cover is arranged between the rotary piston pump and the liquid inlet cylinder. A bracket is inserted into the filter cover, and a filter screen is arranged on the bracket. A cleaning assembly is arranged inside the filter cover. The cleaning assembly includes a threaded rod and a cleaning block. One side of the cleaning block is attached to the bracket. A storage box is integrally formed on one side of the filter cover. The storage box has a storage cavity inside, and a cover plate is installed on the side of the storage box away from the filter cover. This utility model has a reasonable structure and can effectively filter impurities in the liquid entering the piston pump during operation, reducing damage to the inner wall and piston rod of the piston pump caused by impurities in the liquid, and improving the overall corrosion resistance of the device.

[0004] However, when the aforementioned existing technology is used, the piston pump generates noise during operation, which not only affects the operating efficiency of the equipment but also causes noise pollution to the surrounding environment. Utility Model Content

[0005] The purpose of this invention is to provide a low-noise rotary piston pump to solve the problem mentioned in the background art that the piston pump generates noise during operation, which not only affects the operating efficiency of the equipment but also causes noise pollution to the surrounding environment.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a low-noise rotary piston pump, including a rotary piston pump body, a noise reduction mechanism and a heat dissipation mechanism are provided on the outside of the rotary piston pump body.

[0007] The noise reduction mechanism includes a base, the top of which has a sliding groove. A bidirectional lead screw is rotatably connected inside the sliding groove. A moving block is threaded onto the outside of the bidirectional lead screw. A soundproof cover is fixedly connected to the top of the moving block. A threaded rod is installed at one end of the soundproof cover. A fixing plate is installed at one end of the threaded rod. A shock-absorbing spring is fixedly connected to one end of the fixing plate. A shock-absorbing plate is fixedly connected to one end of the shock-absorbing spring. A shock-absorbing pad is installed at one end of the shock-absorbing plate.

[0008] Preferably, the rotary piston pump body is screwed to the top of the base, and a handle is installed at one end of the bidirectional lead screw.

[0009] Preferably, one end of the soundproof cover has a through hole, and an airbag is installed inside the through hole.

[0010] Preferably, a limiting telescopic rod is fixedly connected to one end of the fixing plate, and one end of the limiting telescopic rod is fixedly connected to one end of the soundproof cover.

[0011] Preferably, the heat dissipation mechanism includes a heat dissipation pipe, a heat exhaust pipe, and heat dissipation holes. A support block is installed on the inner side of the heat dissipation pipe. A rotating shaft is rotatably connected to the middle of the support block. A cooling fan is fixedly connected to the outside of the rotating shaft. A first gear is installed at one end of the rotating shaft, and a second gear meshes at one end of the first gear.

[0012] Preferably, one end of both the heat dissipation pipe and the heat exhaust pipe is fixedly connected to one end of the rotary piston pump body, and one end of the heat exhaust pipe passes through the base and extends to the outside of the base.

[0013] Preferably, multiple heat dissipation holes are provided, all of which are located on the outside of the base, and sound-absorbing cotton is installed on the inside of both the heat dissipation holes and the heat exhaust pipe.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] Firstly, this utility model mounts the rotary piston pump body on a base. Then, by rotating a two-way lead screw, two moving blocks move towards each other, causing two soundproof covers to move towards each other until they are in contact, enclosing the rotary piston pump body within them. Simultaneously, the rotary piston pump body passes through a through-hole in the outside of the soundproof cover. Inflating the air bladder within the through-hole seals the through-hole, thus isolating the motor and pump body of the rotary piston pump body inside the soundproof cover. The soundproof cover isolates the noise generated by the rotary piston pump body during operation. Simultaneously, rotating the threaded rod moves a fixed plate towards the motor portion of the rotary piston pump body. A limiting telescopic rod ensures the fixed plate moves stably, preventing it from tipping over. This continues until the damping pad at one end of the damping plate contacts the motor portion of the rotary piston pump body. The damping plate clamps the motor, reducing its vibration. The damping pad and damping spring further reduce the motor's vibration, thereby reducing the noise generated by the motor's vibration and achieving noise reduction.

[0016] Secondly, this utility model uses a second gear mounted on the rotating rod of the motor section of the rotary piston pump body. When the motor section of the rotary piston pump body is running, it drives the second gear to rotate. This, in turn, drives the first gear to rotate, which in turn drives the rotating shaft to rotate. This causes the cooling fan outside the rotating shaft to rotate, and then blows air into the interior of the rotary piston pump body through the heat dissipation pipe for cooling. The heat is then discharged to the outside of the base through the heat exhaust pipe. At the same time, the heat inside the sound insulation cover can also be discharged to the outside through the heat dissipation holes. The sound-absorbing cotton inside the heat dissipation holes and heat exhaust pipes prevents noise from being transmitted, thus completing the cooling and heat dissipation operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A low-noise rotary piston pump includes a rotary piston pump body 1, a noise reduction mechanism 2 and a heat dissipation mechanism 3 on the outside of the rotary piston pump body 1.

[0026] The noise reduction mechanism 2 includes a base 21, with a groove on the top of the base 21. A two-way lead screw 22 is rotatably connected inside the groove. A moving block 23 is threadedly connected to the outside of the two-way lead screw 22. A soundproof cover 24 is fixedly connected to the top of the moving block 23. A threaded rod 25 is installed at one end of the soundproof cover 24. A fixing plate 26 is installed at one end of the threaded rod 25. A shock-absorbing spring 27 is fixedly connected to one end of the fixing plate 26. A shock-absorbing plate 28 is fixedly connected to one end of the shock-absorbing spring 27. A shock-absorbing pad 29 is installed at one end of the shock-absorbing plate 28.

[0027] The rotary piston pump body 1 is screwed to the top of the base 21, and a handle is installed at one end of the bidirectional lead screw 22.

[0028] One end of the soundproof cover 24 has a through hole, and an airbag is installed inside the through hole.

[0029] One end of the fixed plate 26 is fixedly connected to a limiting telescopic rod, and one end of the limiting telescopic rod is fixedly connected to one end of the soundproof cover 24.

[0030] Through the above technical solution, by mounting the rotary piston pump body 1 on the base 21, and then rotating the double-acting screw 22 by the handle, the two moving blocks 23 are driven to move towards each other, thereby causing the two soundproof covers 24 to move towards each other until the two soundproof covers 24 are in contact, surrounding the rotary piston pump body 1 inside the two soundproof covers 24. At the same time, the rotary piston pump body 1 passes through the through hole on the outside of the soundproof cover 24, and then the through hole is sealed by inflating the air bladder in the through hole, thereby isolating the motor and pump body of the rotary piston pump body 1 inside the soundproof cover 24, and isolating the rotary piston pump body 1 from the soundproof cover 24. The noise generated during the operation of the rotary piston pump body 1 is simultaneously reduced by rotating the threaded rod 25, which drives the fixed plate 26 towards the motor part of the rotary piston pump body 1. The limiting telescopic rod makes the fixed plate 26 more stable during movement and prevents it from flipping over, until the shock-absorbing pad 29 at one end of the shock-absorbing plate 28 contacts the motor part of the rotary piston pump body 1. The shock-absorbing plate 28 clamps the motor, reducing the motor's vibration. At the same time, the shock-absorbing pad 29 and the shock-absorbing spring 27 further reduce the motor's vibration, thereby reducing the noise generated by the motor's vibration, thus completing the noise reduction operation and achieving the effect of reducing noise pollution.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the following is obtained: the heat dissipation mechanism 3 includes a heat dissipation pipe 31, a heat exhaust pipe 37, and a heat dissipation hole 38. A support block 32 is installed on the inner side of the heat dissipation pipe 31. A rotating shaft 33 is rotatably connected to the middle of the support block 32. A cooling fan 34 is fixedly connected to the outside of the rotating shaft 33. A first gear 35 is installed at one end of the rotating shaft 33. A second gear 36 is meshed at one end of the first gear 35.

[0033] One end of the heat dissipation pipe 31 and the heat exhaust pipe 37 are fixedly connected to one end of the rotary piston pump body 1. One end of the heat exhaust pipe 37 passes through the base 21 and extends to the outside of the base 21.

[0034] Multiple heat dissipation holes 38 are provided, and all of the heat dissipation holes 38 are located on the outside of the base 21. Sound-absorbing cotton is installed on the inside of the heat dissipation holes 38 and the heat dissipation pipe 37.

[0035] Through the above technical solution, the second gear 36 is installed on the rotating rod of the motor part of the rotary piston pump body 1. When the motor part of the rotary piston pump body 1 is running, it drives the second gear 36 to rotate. This in turn drives the first gear 35 to rotate, which in turn drives the rotating shaft 33 to rotate. This causes the cooling fan 34 outside the rotating shaft 33 to rotate. Then, the air is blown into the interior of the rotary piston pump body 1 through the heat dissipation pipe 31 for heat dissipation and cooling. Then, the heat is discharged to the outside of the base 21 through the heat dissipation pipe 37. At the same time, the heat inside the sound insulation cover 24 can also be discharged to the outside through the heat dissipation hole 38. The sound-absorbing cotton inside the heat dissipation hole 38 and the heat dissipation pipe 37 prevents noise from being transmitted, thereby completing the cooling and heat dissipation operation.
