Technical Field

[0001] The utility model belongs to the technical field of recycling and circulation of vacuum pump sealing water, and particularly relates to a small vacuum pump sealing water recycling and circulation system. Background Technique

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physical-chemical methods to evacuate the container to be evacuated to obtain a vacuum. Its operating principle is mainly to continuously extract gas, reduce the number of gas molecules in the container to be evacuated, and thus achieve a vacuum state.

[0003] The vacuum pumps in the prior art do not have the function of recycling the sealing water, so that the sealing water of the vacuum pump is directly discharged to the outside after use. When used next time, new water source is filled into the inside of the vacuum pump again, which will waste a large amount of water resources during the use of the vacuum pump, and thus increase the use cost of the vacuum pump.

[0004] Therefore, we propose a small vacuum pump sealing water recycling and circulation system to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the vacuum pump in the prior art does not have the function of recycling the sealing water, and to propose a small vacuum pump sealing water recycling and circulation system.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figures 1-5 The present embodiment provides a small vacuum pump sealing water recycling circulation system, which includes a base 1, on the upper surface of which a vacuum pump body 2 and a water tank 3 are fixedly mounted, and on the bottom surface of the base 1 two sets of universal wheels 16 are fixedly mounted, and on the outer surface of each universal wheel 16 a brake pad 17 is fixedly mounted. The installation of the universal wheel 16 facilitates workers to move the device, thereby increasing the convenience of moving the device. The installation of the brake pad 17 plays a role in locking the universal wheel 16, thereby minimizing the phenomenon of the universal wheel 16 rotating on its own, thereby ensuring the stability of the device.

[0024] The water outlet end of the vacuum pump body 2 is fixedly connected with a connecting pipe 4, and the other end of the connecting pipe 4 passes through the interior of the water tank 3. The water inlet end of the vacuum pump body 2 is fixedly connected with a delivery pipe 5, and the other end of the delivery pipe 5 passes through the interior of the water tank 3. The outer surface of the delivery pipe 5 is fixedly connected with a flow switch 6. The installation of the flow switch 6 can ensure that water enters the vacuum pump body 2 during operation to prevent it from being damaged by heat due to idling. The back of the water tank 3 is fixedly connected with a drain pipe 18, and a valve 19 is fixedly installed on the outer surface of the drain pipe 18. The installation of the drain pipe 18 and the valve 19 makes it convenient for workers to discharge and replace the water source inside the water tank 3.

[0025] A sleeve heat exchanger 7 is fixedly installed on the outer surface of the water tank 3. A filter screen 8 is snap-fitted inside the water tank 3. A float valve 9 is fixedly communicated with the left side surface of the water tank 3. The installation of the float valve 9 can timely supplement the water level inside the water tank 3. A controller 10 is fixedly installed on the upper surface of the base 1. A protective box 20 is fixedly installed on the upper surface of the base 1. A protective cover 21 is movably hinged on the upper surface of the protective box 20. The installation of the protective box 20 and the protective cover 21 plays a role in safely protecting the controller 10, thereby minimizing the risk of the controller 10 being collided by the outside world.

[0026] A rotating motor 11 is arranged above the water tank 3. The output end of the rotating motor 11 penetrates through the water tank 3 and is fixedly installed with a turntable 12. Two support frames 24 are fixedly installed on the outer surface of the rotating motor 11. The bottom surface of each support frame 24 is fixedly connected with the upper surface of the water tank 3. The installation of the support frame 24 plays a role in fixing the rotating motor 11, thereby preventing the rotating motor 11 from rotating during operation, and further ensuring the stability of the rotating motor 11 during operation.

[0027] A connecting column 13 is fixedly installed on the bottom surface of the turntable 12. A moving frame 14 is arranged below the turntable 12. The inner wall of the moving frame 14 is slidably connected with the outer surface of the connecting column 13. The outer surface of the moving frame 14 is slidably connected with two limit seats 25. The upper surface of each limit seat 25 is fixedly connected with the inner top wall of the water tank 3. The installation of the limit seat 25 plays a role in restricting the moving track of the moving frame 14, thereby minimizing the risk of the moving frame 14 deviating from the moving track during movement, and further ensuring the stability of the moving frame 14 during movement.

[0028] Two scraper frames 15 are fixedly installed on the outer surface of the moving frame 14. The bottom surface of each scraper frame 15 is in contact with the upper surface of the filter screen 8. A slider 26 is fixedly installed on the front surface of each scraper frame 15. A chute 27 is opened on the inner wall of the water tank 3. Each slider 26 is slidably connected inside the chute 27. The installation of the slider 26 and the chute 27 plays a role in restricting the moving track of the scraper frame 15, thereby minimizing the risk of the scraper frame 15 deviating from the moving track during movement, and further ensuring the stability of the scraper frame 15 during movement.

[0029] A lock block 22 is fixedly installed on the left side surface of the protective cover 21. A lock frame 23 is fixedly installed on the left side surface of the protective box 20. The lock block 22 is snap-fitted inside the lock frame 23. The installation of the lock block 22 and the lock frame 23 plays a role in locking the protective cover 21, thereby minimizing the risk of the protective cover 21 opening by itself, and further ensuring the stability of the protective cover 21.

[0030] The working principle of the present utility model is as follows: When in use, the worker turns on the vacuum pump main body 2, the flow switch 6, the sleeve heat exchanger 7 and the rotating motor 11 through the controller 10. During the operation of the vacuum pump main body 2, the water source of the vacuum pump main body 2 enters the interior of the water tank 3 through the connecting pipe 4. At the same time, the water source inside the water tank 3 enters the interior of the vacuum pump main body 2 through the conveying pipe 5 for replenishment. During the circulation process, the sleeve heat exchanger 7 absorbs the heat of the water source inside the water tank 3, and at the same time, the filter screen 8 filters the impurities in the water source, thereby achieving the purpose of recycling and circulating the sealing water. At the same time, the power provided by the rotating motor 11 drives the turntable 12 to rotate, so that the turntable 12 drives the connecting column 13 to rotate. Then, under the restriction of the limit seat 25, the connecting column 13 drives the moving frame 14 to reciprocate. At the same time, the moving frame 14 drives the scraping frame 15 to move, so that the scraping frame 15 scrapes the impurities on the filter screen 8, thereby ensuring the smoothness of the filter screen 8 and avoiding the phenomenon of unsmooth flow of the sealing water.
