Description

Technical Field

[0001] This utility model relates to the field of peristaltic pump technology, specifically a noise-reducing industrial peristaltic pump. Background Technology

[0002] An industrial peristaltic pump is a fluid transfer device that uses dynamic principles to transport fluids. Its core structure consists of two parts: a pump tube and a driver. In the pump tube, the fluid is sealed inside and is squeezed and released by two or more rollers, driving the fluid to flow forward. The driver, on the other hand, uses an electric motor to drive a drive shaft to rotate, which causes the rollers to squeeze and release the fluid in the pump tube in a certain sequence.

[0003] Chinese Patent Publication No. CN207583601U discloses a novel industrial peristaltic pump, comprising a pump cover, a drive shaft, a fixed base, a rotating shaft, a transmission box, and a driven shaft. A pump body is fixed below the pump cover, and inlet / outlet connectors are installed on the front side of the pump body. A motor is connected to the right side of the drive shaft, and a vibration-damping base is installed below the motor. The pump body is fixed above the transmission box, and rollers are installed on the inner side of the pump body. The driven shaft is connected to the rotating wheel via a pin, and rollers are installed on the outer side of the rotating wheel. The drive shaft and the drive shaft are located on the inner side of the coupling, and the drive shaft is connected to the drive shaft via a wear-resistant pad. This novel industrial peristaltic pump features a vibration-damping base and a vibration-damping pad, which effectively reduces motor vibration during operation. Both the driven gear and the drive gear are bevel gears, improving the overall efficiency of the device. The wear-resistant pad is made of elastic rubber, effectively reducing wear between the drive shaft and the drive shaft, thereby increasing the service life of the entire device.

[0004] Most existing industrial peristaltic pumps have a rigid connection between the motor and the pump head, which causes the vibration force generated by the motor to be transmitted to the pump head. This increases the friction between the contacting components inside the pump head, resulting in noise or friction damage. At the same time, the motor also generates noise. To address this, we propose a noise-reducing industrial peristaltic pump. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-3A noise-reducing industrial peristaltic pump includes a housing 1. A peristaltic pump head 4 is mounted on the left side of the housing 1. A pump head drive shaft 3 is installed inside the pump head 4. A drive pulley 11 is fixedly mounted on the right side of the pump head drive shaft 3. A first connecting bearing 2 is mounted on the outer surface of the pump head drive shaft 3. The pump head drive shaft 3 is movably connected to the housing 1 through the first connecting bearing 2. A fixing block 5 is fixedly mounted on the left side of the inner wall of the housing 1. A limiting movable groove 15 is formed inside the fixing block 5. A limiting movable block 16 is movably mounted inside the limiting movable groove 15. The shape and size of the limiting movable block 16 partially match the shape and size of the inside of the limiting movable groove 15, and the limiting movable block 16 can move inside the limiting movable groove 15. A buffer spring 12 is mounted above the limiting movable block 16. A buffer pulley 7 is mounted at the front end of the limiting movable block 16. A second connecting bearing 13 is installed inside the buffer pulley 7. The buffer pulley 7 is movably connected to the limiting movable block 16 through the second connecting bearing 13. The buffer pulley 7 is elastically connected to the limiting groove 15 via the buffer spring 12. A transmission belt 6 is installed on the outside of the buffer pulley 7. A shock-absorbing pad 10 is installed inside the housing 1. A soundproof box 8 is installed above the shock-absorbing pad 10. The soundproof box 8 is made of sound-absorbing material. A motor 9 is installed inside the soundproof box 8. A motor pulley 14 is installed at the output end of the motor 9. The motor pulley 14 is driven by the transmission belt 6 and the buffer pulley 7. The buffer pulley 7 is driven by the transmission belt 6 and the transmission pulley 11. The motor pulley 14 is driven by the transmission belt 6 and the transmission pulley 11. By setting the buffer pulley 7, which can move up and down, the transmission of vibration force generated by the motor 9 during operation is weakened, thereby reducing noise generation and achieving a noise reduction effect. At the same time, it avoids the internal components of the peristaltic pump head 4 and the pump head drive shaft 3 from being affected by vibration force and causing friction damage and noise generation. The soundproof box 8 and the shock-absorbing pad 10 can effectively isolate the transmission of noise and achieve a good noise reduction effect.

[0022] Please see Figure 1 A noise-reducing industrial peristaltic pump includes a heat sink 17 mounted above a housing 1. Silent fans 19 are mounted on both sides of the heat sink 17. A Peltier 20 is installed inside the heat sink 17. A first heat-conducting plate 18 is mounted on the hot end of the Peltier 20, and a second heat-conducting plate 21 is mounted on the cold end of the Peltier 20. Thermally conductive silicone 22 is installed below the second heat-conducting plate 21. The second heat-conducting plate 21 passes through the inner walls of the housing 1 and the soundproof box 8. The thermally conductive silicone 22 wraps around the outer surface of a motor 9. The heat generated by the motor 9 during operation is transferred to the first heat-conducting plate 18 and dissipated through the Peltier 20, the second heat-conducting plate 21, and the thermally conductive silicone 22, preventing the motor 9 from overheating and being damaged.

[0023] Working Principle: When using this noise-reducing industrial peristaltic pump, the motor 9 is first powered on, driving the motor pulley 14 to rotate. The motor pulley 14, through the transmission belt 6, drives the buffer pulley 7 and the transmission pulley 11 to rotate. The operation of the motor 9 generates vibration, which causes the motor pulley 14 to oscillate, putting tension on the transmission belt 6. The transmission belt 6 then applies this tension to the buffer pulley 7 and the transmission pulley 11. When the buffer pulley 7 is subjected to this force, the limiting block 16 moves up and down within the limiting groove 15, eliminating the tension. This greatly reduces the force acting on the transmission pulley 11, thus preventing the pump head drive shaft 3 and the peristaltic pump head 4 from vibrating under the influence of force, reducing noise generation and simultaneously reducing... The friction between the contact surfaces of each component, the soundproof box 8 and the shock-absorbing pad 10, through their own characteristics, play a role in shock absorption and sound insulation, blocking or reducing the transmission of noise, and thus reducing noise. Finally, the peristaltic pump head 4 (model: YZ15) is existing technology and will not be described in detail here. Finally, the controller controls the silent fan 19 and Peltier 20 to be powered on. Peltier 20 is existing technology and will not be described in detail here. Peltier 20 transfers the heat generated by the motor 9 during operation to the first heat-conducting plate 18 through the second heat-conducting plate 21 and the thermal conductive silicone 22. The silent fans 19 (model: DFX9025) on both sides of the heat sink 17 blow air to dissipate the heat on the first heat-conducting plate 18, thereby cooling the motor 9. This is the working principle of this noise-reducing industrial peristaltic pump.
