Description

Technical Field

[0001] This utility model relates to the field of vacuum technology, and in particular to a self-priming device for vacuuming industrial pumps. Background Technology

[0002] With increasingly stringent environmental policies, industrial production is paying more attention to the energy efficiency and environmental friendliness of equipment. Industrial pumps, through optimized structural design and working principles, effectively reduce energy consumption and waste during operation, which aligns with the development trend of energy conservation and environmental protection.

[0003] Related technology can be found in Chinese Patent No. CN218207100U, which discloses a self-priming pump venting device, relating to the field of self-priming pump pipeline design technology. The device includes a self-priming pump with its inlet connected to an inlet pipe and its outlet connected to an outlet pipe. The other end of the inlet pipe extends into a sewage tank. A pressure pipe is provided between the inlet and outlet pipes, and a first valve body is provided on the pressure pipe to control its opening and closing. This utility model provides a self-priming pump venting device that introduces pressurized liquid from the pump outlet into the pump inlet through the pressure pipe, increasing the self-priming flow rate and solving the problem of automatic water filling caused by a malfunctioning inlet solenoid valve in existing self-priming pumps. Furthermore, it discharges the gas-water mixture inside the self-priming pump during the initial startup phase through a cooling pipe, controlling the liquid temperature inside the pump and preventing vaporization that could cause the pump to lose its self-priming ability. This solves the problem of automatic water filling caused by vaporization when pumping high-temperature liquids in existing self-priming pumps.

[0004] Regarding the aforementioned technologies, in actual industrial production and equipment application scenarios, there are many differences in the design of self-priming pumps of different models and specifications. Therefore, the sizes of the pump inlet and outlet of the self-priming pump also differ. The above-mentioned pipelines are often determined in terms of size and connection method based on specific models and specifications of self-priming pumps. Once installed, when it is necessary to replace the self-priming pump with a different pump inlet size, the existing pipeline system may not be compatible, resulting in poor flexibility of the device. Utility Model Content

[0005] To improve the flexibility of self-priming devices for industrial pumps, this application provides a self-priming device for vacuuming industrial pumps.

[0006] This application provides a self-priming device for vacuuming industrial pumps, which adopts the following technical solution:

[0007] A self-priming device for vacuuming an industrial pump includes a base, a water tank and a pump body fixedly mounted on the upper end of the base, an inlet and an outlet of water, a connecting pipe connected to the inlet, an outlet pipe inside the water tank, an adjusting pipe at the end of the outlet pipe away from the water tank, the adjusting pipe being inserted into the outlet pipe and being retractable, the end of the adjusting pipe away from the outlet pipe being connected to the connecting pipe, two sliding rods fixedly mounted on the outside of the adjusting pipe, the two sliding rods being located on both sides of the adjusting pipe, the sliding rods passing through the outlet pipe, the outlet pipe having grooves corresponding to the sliding rods, the sliding rods being slidably connected to the outlet pipe along the length of the grooves, a sealing element being provided at the grooves to reduce the probability of water leakage from the outlet pipe, a positioning element being provided at the end of the sliding rod away from the adjusting pipe to position the sliding rod.

[0008] By adopting the above technical solution, the water in the pump body's starting water tank is transmitted from the outlet pipe to the regulating pipe, then from the regulating pipe to the connecting pipe, and finally from the inlet to the pump body. The regulating pipe is telescopic, which facilitates the connection of connecting pipes with different pipe sizes. The sealing component blocks the slide groove to reduce the probability of the slide groove flowing out of the outlet pipe. The sliding rod slides horizontally, and the movement of the sliding rod drives the regulating pipe to move, thereby adjusting the length of the pipe. After the adjustment is completed, the positioning component positions the sliding rod, which improves the flexibility of the device.

[0009] Optionally, the regulating tube includes several arc-shaped blocks, an arc-shaped plate is inserted between two adjacent arc-shaped blocks, the arc-shaped plate is slidably connected to the arc-shaped blocks along the width direction of the arc-shaped blocks, and two elastic elements are fixed between two adjacent arc-shaped plates, with the two elastic elements located at the two ends of the arc-shaped plates respectively.

[0010] By adopting the above technical solution, adjacent arc-shaped blocks are connected by arc-shaped plates, and the arc-shaped plates are slidably connected to the arc-shaped blocks. This structure allows the regulating tube to flexibly extend and retract, thereby adapting to the needs of different connecting tube sizes. At the same time, two elastic elements set between two adjacent arc-shaped plates ensure the stability of the regulating tube in the extension and retraction state, improving the reliability of the device.

[0011] Optionally, the positioning component includes a locking rod and a locking plate. The locking plate is located at the end of the slide rod away from the regulating pipe. The locking plate is arranged horizontally and is slidably connected to the slide rod vertically. The locking plate has several through holes along the horizontal direction. The locking rod is fixed to the outside of the water outlet pipe. The locking rod is arranged vertically and is inserted into any through hole and engaged with the inner wall of the through hole.

[0012] By adopting the above technical solution, the sliding rod moves laterally, causing the locking plate to move laterally. After the position is adjusted, the locking block moves vertically, allowing the locking rod to be inserted into the corresponding through hole. This reduces the probability of the sliding rod shifting due to accidents, thereby improving the stability of the device.

[0013] Optionally, the sealing component includes a connecting plate located at the chute, a sliding rod passing through the connecting plate, the connecting plate being inserted into the inner wall of the outlet pipe, and the connecting plate being slidably connected to the inner wall of the outlet pipe in the transverse direction.

[0014] By adopting the above technical solution, the connecting plate is inserted into the inner wall of the water outlet pipe and slidably connected to it, so that the connecting plate can be adjusted according to the movement of the slide rod, while maintaining the sealing effect at the slide groove. This design improves the sealing performance of the device, reduces the risk of liquid leakage, and thus improves the reliability of the device.

[0015] Optionally, the pump body includes a motor, a rotating shaft, and an impeller. The motor is fixed to the upper end of the base, the rotating shaft is coaxially fixed with the motor output shaft, the impeller is located at the end of the rotating shaft away from the motor, and the rotating shaft passes through the impeller and is fixedly connected to the impeller.

[0016] By adopting the above technical solution, the motor starts and drives the shaft to rotate, the shaft rotates and drives the impeller to rotate, and the impeller rotates to realize the functions of pumping and conveying liquid. This structural design enables the pump body to complete the vacuuming and self-priming operations efficiently and stably, improving the working efficiency and reliability of the pump body.

[0017] Optionally, an outer ring is fixedly provided at one end of the water outlet pipe near the regulating pipe, and an inner ring is inserted inside the outer ring. The inner ring can also be slidably connected to the regulating pipe laterally. An elastic element two is fixedly provided between the inner ring and the outer ring, and the elastic element two is used to drive the inner ring to slide.

[0018] By adopting the above technical solution, the outer and inner rings make the regulating pipe more stable when sliding laterally. At the same time, the elastic element 2 drives the inner ring to move towards the outer ring, thereby reducing the probability of water leakage caused by the expansion and contraction of the regulating pipe, which helps to ensure smooth water flow and improve the reliability of the device.

[0019] Optionally, a sealing ring is provided between the inner ring and the regulating pipe to reduce the probability of liquid leakage.

[0020] By adopting the above technical solution, the sealing ring fills the unevenness between the inner ring and the regulating pipe through elastic deformation, forming a physical barrier, cutting off the liquid leakage channel, reducing the probability of liquid leakage, and improving the sealing performance of the device.

[0021] Optionally, a mounting block is provided at the end of the connecting pipe away from the water inlet. The mounting block is connected to the connecting pipe. A groove is provided in the mounting block, and a filter screen is provided in the groove. The filter screen is inserted into the groove and is engaged with the inner wall of the groove. A sealing cap is fixedly provided at the upper end of the filter screen, and a handle is fixedly provided on the side of the sealing cap away from the filter screen.

[0022] By adopting the above technical solution, the filter screen effectively intercepts impurities in the connecting pipe, reducing the probability of impurities entering the pump body through the connecting pipe and damaging components such as the impeller, thereby improving the pump's service life and operating efficiency. The matching design of the sealing cover and handle facilitates quick installation and removal of the filter screen, simplifying the maintenance process. At the same time, the connection structure between the mounting block and the connecting pipe ensures smooth water flow, reduces fluid resistance, and improves the overall operational stability of the device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The regulating pipe is telescopic, which facilitates the connection of pipes with different pipe opening sizes. The sliding rod moves laterally, and the movement of the sliding rod drives the regulating pipe to adjust the length of the pipe, thereby improving the flexibility of the device.

[0025] 2. The sliding rod moves laterally, causing the clamping plate to move laterally. After the position is adjusted, the clamping block moves vertically, allowing the clamping rod to be disassembled into the corresponding through hole, reducing the probability of the sliding rod being displaced due to accident, thereby improving the stability of the device.

[0026] 3. The filter effectively intercepts impurities in the connecting pipe, reducing the probability of impurities entering the pump body through the connecting pipe and damaging components such as the impeller, thereby improving the service life of the pump body. Attached Figure Description

[0033] This application discloses a self-priming device for vacuuming industrial pumps. Example

[0034] Reference Figure 1 and Figure 2 A self-priming device for vacuuming an industrial pump includes a base 1, with a pump body 11 fixed to the upper end of the base 1. The pump body 11 has an inlet 111 and an outlet 112. A connecting pipe 13 is provided at the inlet 111 and is connected to the inlet 111. An adjusting pipe 15 is provided at the end of the connecting pipe 13 away from the outlet 112. The adjusting pipe 15 includes several arc-shaped blocks 151. An arc-shaped plate 152 is inserted between two adjacent arc-shaped blocks 151. The arc-shaped plate 152 is slidably connected to the arc-shaped blocks 151 along the width direction of the arc-shaped blocks 151. This structure allows the adjusting pipe 15 to flexibly extend and retract, thereby adapting to the needs of different sizes of the connecting pipe 13 and improving the flexibility of the device.

[0035] Reference Figure 2 and Figure 3 Two elastic elements 153 are fixed between two adjacent arc plates 152. The two elastic elements 153 are located at both ends of the arc plate 152 respectively, to ensure the stability of the regulating tube 15 in the extension and retraction state, facilitate the adjustment of the size of the extension tube opening, and improve the convenience of using the device.

[0036] Reference Figure 2 and Figure 3 The regulating pipe 15 is provided with an outlet pipe 14 at the end away from the connecting pipe 13. The regulating pipe 15 is inserted into the outlet pipe 14. A water tank 12 is provided on one side of the pump body 11. The water tank 12 is fixedly connected to the base 1. The end of the outlet pipe 14 away from the regulating pipe 15 is connected to the water tank 12. Two sliding rods 154 are fixedly provided on the outside of the regulating pipe 15. The two sliding rods 154 are located on both sides of the regulating pipe 15. The outlet pipe 14 is provided with a sliding groove 141 corresponding to the sliding rod 154 in the transverse direction. The sliding rod 154 passes through the outlet pipe 14 and is slidably connected to the outlet pipe 14 along the length direction of the sliding groove 141, thereby adjusting the length of the entire pipe and improving the flexibility of the device.

[0037] Reference Figure 4 A connecting plate 142 is provided at the chute 141, and a sliding rod 154 passes through the connecting plate 142. The connecting plate 142 is inserted into the inner wall of the water outlet pipe 14, and the connecting plate 142 is slidably connected to the inner wall of the water outlet pipe 14 in the transverse direction, so that the connecting plate 142 is adjusted with the movement of the sliding rod 154 to ensure the sealing effect at the chute 141. This design improves the sealing performance of the device, reduces the risk of liquid leakage, and thus improves the reliability of the device.

[0038] Reference Figure 4 A positioning element is provided at the end of the slide rod 154 away from the regulating pipe 15. The positioning element includes a locking rod 143 and a locking plate 155. The locking plate 155 is located at the end of the slide rod 154 away from the regulating pipe 15. The locking plate 155 is arranged horizontally and is slidably connected to the slide rod 154 vertically. The slide rod 154 moves horizontally, causing the locking plate 155 to move horizontally. The locking plate 155 has several through holes 156 opened horizontally. The locking rod 143 is fixed to the outside of the water outlet pipe 14. The locking rod 143 corresponds to the locking plate 155 one by one. After the position of the slide rod 154 is adjusted by the locking rod 143 being arranged vertically, the locking block is moved vertically so that the locking rod 143 passes through the locking block and is inserted into the corresponding through hole 156, reducing the probability of the slide rod 154 being displaced due to accidents, thereby improving the stability of the device.

[0039] Reference Figure 3 and Figure 4 An outer ring 146 is fixed at one end of the outlet pipe 14 near the regulating pipe 15. An inner ring 145 is inserted inside the outer ring 146. The inner ring 145 can also slide laterally with the regulating pipe 15, making the regulating pipe 15 more stable when adjusting the size. An elastic element 147 is fixed between the inner ring 145 and the outer ring 146. The elastic element 147 drives the inner ring 145 to move towards the outer ring 146, thereby reducing the probability of water leakage caused by the expansion and contraction of the regulating pipe 15, which helps to ensure smooth water flow and thus improves the reliability of the device.

[0040] Reference Figure 2 The pump body 11 includes a motor 113, a rotating shaft 114, and an impeller 115. The motor 113 is fixed to the upper end of the base 1.

The impeller 115 is located at the end of the rotating shaft 114 away from the motor 113. The rotating shaft 114 passes through the impeller 115 and is fixedly connected to the impeller 115. The rotation of the rotating shaft 114 drives the impeller 115 to rotate. The rotation of the impeller 115 realizes the function of suction and transportation of liquid, ensuring that the water in the water tank 12 is delivered to the pump body 11, thus improving the reliability of the pump body 11.

[0041] Reference Figure 3 A sealing ring 144 is provided between the inner ring 145 and the regulating pipe 15. The sealing ring 144 is made of elastic material. The sealing ring 144 fills the unevenness between the inner ring 145 and the regulating pipe 15 through elastic deformation, forming a physical barrier, reducing the probability of liquid leakage and improving the sealing performance of the device.

[0042] Reference Figure 4An installation block 131 is provided at the end of the connecting pipe 13 away from the inlet 111. The installation block 131 is connected to the connecting pipe 13.

The filter screen 132 is inserted into the groove 133 and is engaged with the inner wall of the groove 133. This effectively intercepts impurities in the connecting pipe 13, reducing the probability of impurities entering the pump body 11 through the connecting pipe 13 and damaging components such as the impeller 115. This improves the service life and working efficiency of the pump body 11. At the same time, it facilitates the disassembly and maintenance of the filter screen 132, improving the convenience of maintenance. A sealing cover 134 is fixedly provided at the upper end of the filter screen 132. A handle 135 is fixedly provided on the side of the sealing cover 134 away from the filter screen 132. The sealing cover 134 further enhances the sealing performance of the structure, reduces the risk of liquid leakage, and also facilitates user operation, improving the convenience of using the device.

[0043] The implementation principle of the self-priming device for vacuuming an industrial pump according to an embodiment of this application is as follows: the sliding rod 154 slides laterally, and the sliding rod 154 moves laterally, causing the regulating pipe 15 to move laterally. The regulating pipe 15 moves laterally to different positions of the outlet pipe 14, thereby realizing the adjustment of the pipe length. When the pipe openings of different connecting pipes 13 are different, the arc block 151 moves towards or away from the outlet pipe 14. Under the action of the elastic element 153, the arc plate 152 seals the gap between the arc plates 152, realizing the flexible adjustment of the size of the telescopic pipe opening, which is convenient to adapt to different models of connecting pipes 13 and improves the flexibility of the device.
