Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, and more specifically to a cooling device for a water ring vacuum pump. Background Art

[0002] The water ring vacuum pump is a commonly used industrial vacuum pump that uses the interaction between water and gas to achieve vacuum extraction. When the water ring vacuum pump is running, due to the rotation of the impeller, water is thrown to the inner wall of the pump chamber to form a water ring. At the same time, the water ring will form a certain centrifugal force, and under the action of the centrifugal force, a gas compression area is formed. When the gas enters the vacuum pump, it is compressed by the water ring and the impeller, and then discharged from the vacuum pump.

[0003] The water ring vacuum pump will generate heat during operation, which is caused by the friction and compression between the gas, the water ring and the impeller. If the temperature is not reduced in time, the temperature of the pump body will continue to rise, affecting the performance and life of the pump. The current water ring vacuum pump cooling device usually uses water cooling to dissipate heat on its surface, but after the water adheres to the pump wall, it will gradually fall due to its own gravity, so that the water and the pump wall cannot be in contact for a long time, and the water cannot evaporate and absorb heat efficiently, resulting in low cooling efficiency. At this time, if the water flow output is increased, although the cooling efficiency can be increased, it will also lead to a waste of water resources, which is not conducive to sustainable development. Therefore, it needs to be improved and optimized. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 6 As shown, the utility model provides a water ring vacuum pump cooling device, comprising a base 1, a guardrail 2 is fixedly installed on the top of the base 1, and a water ring vacuum pump 3 is arranged inside the guardrail 2;

[0031] The ventilation mechanism is fixedly mounted on the top of the guardrail 2;

[0032] The water storage mechanism is fixedly installed on the left side of the base 1;

[0033] The transmission mechanism is rotatably mounted on the top of the guardrail 2, and one end of the transmission mechanism is fixedly connected to the ventilation mechanism;

[0034] The water outlet mechanism is fixedly installed inside the water ring vacuum pump 3, and one end of the water outlet mechanism is fixedly connected to the water storage mechanism;

[0035] Among them, the water storage mechanism includes a water tank 9 fixedly installed on the left side of the base 1, a fixed bin 10 is fixedly installed on the top of the water tank 9, a water inlet pipe 17 is fixedly installed inside the fixed bin 10, one end of the water inlet pipe 17 is fixedly connected to the transmission mechanism, and the other end is fixedly connected to the sealing bin 18. There are two groups of sealing bins 18, which are located on the upper and lower sides of the water inlet pipe 17. A sealing cover 19 is rotatably installed inside the sealing bin 18. The sealing cover 19 and the inner wall of the sealing bin 18 are elastically connected by a spring 20, and the upper sealing bin 18 and the water outlet mechanism are connected to each other.

[0036] When cooling operation is required, the staff places the water ring vacuum pump 3 inside the guardrail 2 and ensures that there is enough water inside the water tank 9, and then starts the double-axis motor 5. The operation of the double-axis motor 5 drives the gear 1 8 and the fan blade 6 to rotate at the same time. The rotation of the fan blade 6 cools the water ring vacuum pump 3 at its bottom, and the rotation of the gear 1 8 drives the gear 2 11 to rotate through the transmission belt 12. The rotation of the gear 2 11 drives the drive block 14 to rotate through the transmission rod 13. The rotation of the drive block 14 drives the piston rod 15 to perform piston operation inside the piston cylinder 16. When the piston rod 15 moves outward, the sealing cover above the water inlet pipe 17 is closed. 19 closes the sealing chamber 18, and the sealing cover 19 under the water inlet pipe 17 is opened. At this time, the spring 20 is compressed, and the water source is sucked into the water inlet pipe 17. When the piston rod 15 moves inward, the spring 20 at the bottom of the water inlet pipe 17 will close the sealing cover 19 due to elastic potential energy, and the sealing cover 19 above the water inlet pipe 17 will be pushed open by the air pressure generated by the piston rod 15, so that the water flows through the sealing chamber 18 into the water outlet pipe 21 and is sprayed out by the atomizing nozzle 22. At this time, the faster the water mist sprayed by the atomizing nozzle 22, the greater the wind speed provided by the fan blade 6, so that the water mist quickly adheres to the outer wall of the water ring vacuum pump 3 and evaporates and absorbs heat.

[0037] Through the operation of the dual-axis motor 5, the gear 8 and the fan blade 6 rotate. The rotation of the fan blade 6 is for air cooling of the water ring vacuum pump 3 at the bottom thereof, and the rotation of the gear 8 outputs the water source inside the water tank 9 to the atomizing nozzle 22, and the water is sprayed by the atomizing nozzle 22 to cool the water ring vacuum pump 3. Compared with the traditional device, the device interconnects the ventilation mechanism and the water storage mechanism through the transmission mechanism, so that when the water mist sprayed by the atomizing nozzle 22 is faster, the wind speed provided by the fan blade 6 is also greater, so that the water mist quickly adheres to the outer wall of the water ring vacuum pump 3, and evaporates and absorbs heat, thereby improving the heat dissipation efficiency of the water flow.

[0038] Among them, a guide groove 27 is fixedly opened at the bottom of the base 1;

[0039] The collecting mechanism is fixedly mounted on the bottom of the base 1;

[0041] The staff fixes the water ring vacuum pump 3 on the top of the base 1. When the heat dissipation operation is performed, due to the setting of the guide groove 27, the unevaporated water flows through the guide groove 27 and falls into the water storage bin 24 for collection. The staff can move the fixed head 25 to separate the fixed head 25 from the water storage bin 24. At this time, the staff can take out the water storage bin 24 and collect the accumulated water inside it. When the collection is completed, the staff can reset the water storage bin 24 and loosen the fixed head 25. At this time, due to the elastic potential energy of the spring 26, the fixed head 25 can fix the water storage bin 24 again.

[0042] The water flows into the water storage tank 24 through the guidance of the guide groove 27, and then the water storage tank 24 is fixed through the cooperation of the fixing head 25 and the spring 26. Compared with the traditional device, this device can collect the accumulated water while facilitating the fixing and installation of the water storage tank 24, thereby improving the collection efficiency and saving water resources.

[0043] Among them, the ventilation mechanism includes a vent 4 fixedly installed on the top of the guardrail 2, and a dual-axis motor 5 is fixedly installed inside the vent 4. One end of the dual-axis motor 5 is fixedly connected to the fan blade 6, and the other end is fixedly connected to the gear 8. The gear 8 is rotatably installed on the top of the filter plate 7, and the filter plate 7 is fixedly installed on the top of the guardrail 2.

[0044] The staff starts the double-axis motor 5, and the operation of the double-axis motor 5 drives the gear 1 8 and the fan blade 6 to rotate at the same time. The rotation of the fan blade 6 is used for air cooling of the water ring vacuum pump 3 at the bottom thereof.

[0045] Among them, the transmission mechanism includes a gear 1 8 rotatably installed on the top of the filter plate 7, and the transmission mechanism also includes a gear 2 11 rotatably installed on the top of the fixed bin 10. The gear 1 8 and the gear 2 11 are connected by a transmission belt 12. The bottom of the gear 2 11 is fixedly connected to the transmission rod 13. The transmission rod 13 penetrates into the interior of the fixed bin 10 and is fixedly connected to the driving block 14.

[0046] The rotation of gear 1 8 drives gear 2 11 to rotate through the transmission belt 12 , and the rotation of gear 2 11 drives the driving block 14 to rotate through the transmission rod 13 , and the rotation of the driving block 14 drives the piston rod 15 to perform piston operation inside the piston cylinder 16 .

[0047] The transmission mechanism further includes a piston rod 15 rotatably connected to the driving block 14 . The piston rod 15 is movably sleeved inside a piston cylinder 16 . The piston cylinder 16 and the water inlet pipe 17 are fixedly connected and communicated with each other.

[0048] Among them, the water outlet mechanism includes a water outlet pipe 21 fixedly installed on the inner wall of the guardrail 2, one end of the water outlet pipe 21 is connected to the sealing chamber 18, and the other end is connected to the atomizing nozzle 22, and the atomizing nozzle 22 is fixedly installed on the top of the guardrail 2.

[0049] The water flows into the water outlet pipe 21 through the sealing chamber 18 and is sprayed out by the atomizing nozzle 22. At this time, the faster the water mist is sprayed out by the atomizing nozzle 22, the greater the wind speed provided by the fan blades 6, so that the water mist quickly adheres to the outer wall of the water ring vacuum pump 3 and evaporates to absorb heat.

[0050] There are two groups of fixing heads 25 , both of which are movably mounted on the outer wall of the water storage tank 24 , and one end of the fixing head 25 is elastically connected to the water storage tank 24 via a spring 26 .

[0051] The working principle and use process of this utility model:

[0052] When cooling operation is required, the staff places the water ring vacuum pump 3 inside the guardrail 2 and ensures that there is enough water inside the water tank 9, and then starts the double-axis motor 5. The operation of the double-axis motor 5 drives the gear 1 8 and the fan blade 6 to rotate at the same time. The rotation of the fan blade 6 cools the water ring vacuum pump 3 at its bottom, and the rotation of the gear 1 8 drives the gear 2 11 to rotate through the transmission belt 12. The rotation of the gear 2 11 drives the drive block 14 to rotate through the transmission rod 13. The rotation of the drive block 14 drives the piston rod 15 to perform piston operation inside the piston cylinder 16. When the piston rod 15 moves outward, the sealing cover above the water inlet pipe 17 is closed. 19 closes the sealing chamber 18, and the sealing cover 19 under the water inlet pipe 17 is opened. At this time, the spring 20 is compressed, and the water source is sucked into the water inlet pipe 17. When the piston rod 15 moves inward, the spring 20 at the bottom of the water inlet pipe 17 will close the sealing cover 19 due to elastic potential energy, and the sealing cover 19 above the water inlet pipe 17 will be pushed open by the air pressure generated by the piston rod 15, so that the water flows through the sealing chamber 18 into the water outlet pipe 21 and is sprayed out by the atomizing nozzle 22. At this time, the faster the water mist sprayed by the atomizing nozzle 22, the greater the wind speed provided by the fan blade 6, so that the water mist quickly adheres to the outer wall of the water ring vacuum pump 3 and evaporates and absorbs heat.

[0053] The staff fixes the water ring vacuum pump 3 on the top of the base 1. When the heat dissipation operation is performed, due to the setting of the guide groove 27, the unevaporated water flows through the guide groove 27 and falls into the water storage bin 24 for collection. The staff can move the fixed head 25 to separate the fixed head 25 from the water storage bin 24. At this time, the staff can take out the water storage bin 24 and collect the accumulated water inside it. When the collection is completed, the staff can reset the water storage bin 24 and loosen the fixed head 25. At this time, due to the elastic potential energy of the spring 26, the fixed head 25 can fix the water storage bin 24 again.
