Description

Technical Field

[0001] The invention relates to the technical field of centrifugal pumps, in particular to a shock-absorbing centrifugal pump with an anti-blocking function. Background Art

[0002] Centrifugal pumps are widely used in industry, agriculture and other fields as fluid conveying equipment. They have always been one of the key equipment for conveying liquids, mud, gas and other fluids. With the acceleration of industrialization, the demand for centrifugal pumps has gradually increased, especially in the fields of water treatment, chemical industry, energy, etc., which require pumps to have more efficient and stable working performance. Against this background, the design of traditional centrifugal pumps has gradually developed towards higher efficiency, more energy saving and low noise. In addition, modern centrifugal pumps have higher and higher requirements for system vibration, blockage problems, and long-term stable operation, which has prompted technical research to continue to advance in shock reduction, cleaning, and anti-blocking.

[0003] At present, most centrifugal pumps are designed using traditional motor drive and mechanical transmission, where the motor is usually installed horizontally or vertically. The structure of a traditional centrifugal pump is relatively simple, but it is easy to vibrate at high speeds, which in turn affects the stability and life of the pump. In order to reduce this vibration, the existing technology usually uses shock-absorbing devices, such as shock-absorbing pads, springs, etc., but the effect is limited. As for anti-blocking technology, existing centrifugal pumps often use filters and anti-blocking devices when processing fluids containing impurities, but these technologies are prone to blockage due to the accumulation of impurities after a long period of operation, which in turn affects the performance of the pump.

[0004] The anti-blocking devices in the prior art usually rely on physical methods such as filters and cleaning devices to remove impurities, but these devices are prone to blockage failures caused by the accumulation of impurities, resulting in frequent maintenance. However, when facing high-speed rotation and large flow delivery, vibration is still difficult to effectively control. The mechanical wear caused by vibration reduces the stability of the system, resulting in unstable transmission of the centrifugal pump and energy loss. Therefore, those skilled in the art provide a shock-absorbing centrifugal pump with an anti-blocking function to solve the problems raised in the above background. Summary of the invention

The shock-absorbing shell is provided with a rotating cavity, and the electromagnetic adsorption block is slidably connected to the rotating cavity.

Through the principle of electromagnetic adsorption, the vibration absorption and shock absorption effect are further enhanced. The shock-absorbing shell is provided with a sewage outlet, and a sewage outlet is installed on the sewage outlet, which is used to regularly remove impurities and dirt in the system, keep the inside of the equipment clean, and avoid blocking affecting the system performance. The shock-absorbing shell is also provided with a sewage cleaning outlet, which is connected to the anti-blocking mechanism to ensure that impurities entering the system can be effectively removed during the operation of the equipment to prevent blockage from affecting the normal operation of the pump.

The lifting hydraulic cylinder provides precise lifting control through the hydraulic system to ensure that the cleaning brush can contact the surface of the equipment for effective cleaning when needed. The lifting hydraulic cylinder is tightly connected to the electromagnetic adsorption block, and the electromagnetic adsorption block helps to fix and adjust the working position of the cleaning brush through adsorption, so that it remains stable during the cleaning process and prevents the cleaning effect from being affected by improper position. Through this design, the anti-blocking mechanism can maintain the automatic cleaning function during the operation of the equipment, effectively remove impurities, prevent blockage, and ensure the smooth and efficient operation of the system.

The shock-absorbing shell is connected with the connecting pipe, and the filtered fluid is further transmitted to the outer volute through the connecting pipe to ensure that the fluid is not disturbed by the outside during the flow process, reduce mechanical shock, and further reduce mechanical vibration through the counter-rotation of the vortex generated by the outer volute and the inner volute.

[0027] Compared with the prior art, the present invention has the following beneficial effects: After the fluid enters the water inlet pipe, it is first filtered through the anti-blocking mechanism to remove impurities and prevent blockage; then the fluid enters the shock-absorbing shell for further vibration and impact absorption; finally, after the acceleration of the inner and outer worm gears, the fluid is strongly pressurized and transported to the outside.

[0028] Due to the high-speed rotation and fluid power generated by the centrifugal pump, vibration is easily generated. The shock-absorbing mechanism absorbs the counterweight block through the principle of electromagnetic adsorption, and adjusts the position of the counterweight block in time through the movement of the counterweight rod to play a balancing role, thereby reducing the vibration and impact of the equipment. The electromagnetic adsorption block uses magnetic adsorption to enable the shock-absorbing block to absorb filtered magnetic impurities, further optimizing the shock-absorbing effect. Through electromagnetic adsorption and counterweight adjustment, the shock-absorbing mechanism effectively alleviates the vibration caused by fluid acceleration and mechanical shock, thereby improving the smooth operation of the pump.

[0029] The spiral directions of the inner and outer worm gears are opposite, and the centrifugal force accelerates the fluid to ensure efficient flow and pressurization.

[0046] By adopting the above technical solution, the upper transmission rod 431 is connected to the counterweight rod 22 by transmission, and the movement of the upper transmission rod 431 causes the counterweight rod 22 to move accordingly, thereby driving the counterweight block 23 on the counterweight rod 22 to move accordingly. The counterweight block 23 is connected to the counterweight rod 22 by transmission, and the movement of the counterweight block 23 plays a balancing role during vibration, reducing the impact caused by the unbalanced load. The electromagnetic adsorption block 21 is tightly connected to the counterweight block 23. Through the principle of electromagnetic adsorption, the electromagnetic adsorption block 21 can adsorb or release the movement of filtered magnetic impurities, further adjust the state of the counterweight block 23, and thus accurately control the shock absorption effect.

The surface of the shock-absorbing shell 25 is also provided with a spiral cleaning pattern 256, which can help clean impurities and dirt in a spiral manner, thereby enhancing the cleaning effect.

[0049] The shock absorbing mechanism 2 can effectively reduce the vibration of the equipment and provide a continuous cleaning function to prevent foreign matter and dirt from damaging the performance of the equipment, thereby improving the operating stability of the pump, extending its service life, and ensuring the cleanliness and smoothness of the system during efficient operation.

[0050] Furthermore, the anti-blocking mechanism 1 includes a cleaning brush 11, a cleaning motor 12 and a lifting hydraulic cylinder 13. The cleaning motor 12 and the cleaning brush 11 are transmission-connected, the cleaning motor 12 and the lifting hydraulic cylinder 13 are fastenedly connected, and the lifting hydraulic cylinder 13 and the electromagnetic adsorption block 21 are fastenedly connected.

[0051] By adopting the above technical solution, the cleaning motor 12 is connected to the cleaning brush 11 through a transmission, and the cleaning motor 12 provides power to drive the cleaning brush 11 to perform cleaning work. During the operation of the system, the cleaning brush 11 can automatically clean the impurities and dirt inside the equipment to prevent them from affecting the normal operation of the equipment. The cleaning motor 12 is tightly connected to the lifting hydraulic cylinder 13. The function of the lifting hydraulic cylinder 13 is to adjust the height and position of the cleaning brush 11 to ensure that the cleaning brush 11 can flexibly clean different parts to meet different cleaning needs. The lifting hydraulic cylinder 13 provides precise lifting control through the hydraulic system to ensure that the cleaning brush 11 can contact the surface of the equipment for effective cleaning when needed.

The electromagnetic adsorption block 21 helps to fix and adjust the working position of the cleaning brush 11 through adsorption, so that it remains stable during the cleaning process and prevents the cleaning effect from being affected by improper position. Through this design, the anti-blocking mechanism 1 can maintain the automatic cleaning function during the operation of the equipment, effectively remove impurities, prevent blockage, and ensure the smooth and efficient operation of the system. It realizes cleaning automation and efficiency, reduces the complexity of equipment maintenance, ensures long-term stable operation of the equipment, and greatly extends the service life of the pump.

[0052] Furthermore, the anti-blocking mechanism 1 includes an inlet pipe 14, a connecting pipe 15, an outlet pipe 16 and a stop valve 17. The inlet pipe 14 is connected to the shock-absorbing shell 25, the shock-absorbing shell 25 is connected to the connecting pipe 15, the connecting pipe 15 is connected to the outer volute cavity 332, the inner volute cavity 331 is connected to the outlet pipe 16, and the stop valve 17 is firmly connected to the connecting pipe 15.

[0053] By adopting the above technical solution, the water inlet pipe 14 is connected with the shock-absorbing shell 25, and the fluid enters the shock-absorbing shell 25 through the water inlet pipe 14, and first passes through the filtering mechanism in the shock-absorbing shell 25 to reduce the vibration and impact in the fluid, ensuring that the fluid flows smoothly into the subsequent pipeline. The shock-absorbing shell 25 is connected with the connecting pipe 15, and the filtered fluid is further transmitted to the outer volute 332 through the connecting pipe 15 to ensure that the fluid is not disturbed by the outside during the flow process, reduce mechanical shock, and further reduce mechanical vibration through the vortex generated by the outer volute 332 and the inner volute 331.

[0054] Working principle of the present invention: After the fluid enters the water inlet pipe 14, it is first filtered by the anti-blocking mechanism 1, and impurities are removed and blocked; then the fluid enters the shock-absorbing shell 25 for further vibration and impact absorption; finally, after the acceleration of the inner and outer worm gears 32, the fluid is strongly pressurized and transported to the outside. Due to the high-speed rotation and fluid power generated by the centrifugal pump, vibration is easy to occur. The shock-absorbing mechanism 2 adsorbs the counterweight block 23 through the principle of electromagnetic adsorption, and adjusts the position of the counterweight block 23 in time through the movement of the counterweight rod 22, which plays a balancing role, thereby reducing the vibration and impact of the equipment. The electromagnetic adsorption block 21 uses the magnetic adsorption effect to enable the shock-absorbing block to adsorb the filtered magnetic impurities, further optimizing the shock-absorbing effect. Through the electromagnetic adsorption effect and counterweight adjustment, the shock-absorbing mechanism 2 effectively alleviates the vibration caused by fluid acceleration and mechanical impact, thereby improving the smooth operation of the pump. The spiral directions of the inner worm gear 31 and the outer worm gear 32 are opposite, and the fluid is accelerated by the action of centrifugal force to ensure its efficient flow and pressurization effect. The centrifugal housing 33 is tightly connected and communicated with the shock absorbing mechanism 2, ensuring that the fluid can be pressurized while effectively absorbing vibrations, thereby avoiding mechanical wear and damage caused by high rotation speed.
