Description

Technical Field

[0001] This utility model relates to the field of condensation technology for corrosion-resistant vacuum systems, specifically to a condensation device for corrosion-resistant vacuum systems. Background Technology

[0002] A corrosion-resistant vacuum system is a vacuum system specifically designed for handling corrosive gases. Its main characteristic is the use of corrosion-resistant materials, such as polytetrafluoroethylene (PTFE), to resist the erosion of organic substances, acids, and alkalis. This system is commonly used in the chemical, pharmaceutical, and petrochemical industries to handle highly corrosive samples or gases. In a corrosion-resistant vacuum system, a condenser condenses high-temperature vapor into liquid, thereby lowering the system temperature and ensuring its normal operation.

[0003] In vacuum systems used in chemical, pharmaceutical, and electroplating industries, the liquid produced during the condensation process of corrosive media often carries solid particles. Existing condensation devices mostly use simple collection tanks or external filters to treat the condensate. Unfiltered particles enter downstream pumps, valves, pipelines, or recovery systems with the condensate, leading to increased wear, seal failure, and secondary corrosion. Manual disassembly and cleaning of filters requires frequent shutdowns, and operators are in direct contact with corrosive media, posing safety risks and reducing production efficiency. Therefore, we propose a corrosion-resistant vacuum system condensation device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a corrosion-resistant vacuum system condensation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant vacuum system condensation device, comprising an installation box, a condenser tube fixedly installed inside the installation box, an installation frame fixedly installed below the installation box, an installation plate provided on the installation frame, two sets of symmetrically distributed screen frames embedded in the installation plate, the screen frames being located between the condenser tube and the drain pipe, the installation plate being rotatably connected to the installation frame via a rotating shaft, a first gear sleeved on the installation plate, a first rack slidably installed inside the installation frame, a cylinder fixedly installed inside the installation frame, the first rack meshing with the first gear, the first rack being fixedly connected to the output end of the cylinder piston rod, a movable seat slidably installed on the installation frame, two sets of symmetrically distributed scrapers rotatably installed inside the movable seat, the two sets of scrapers being located on both sides of the installation plate, and the two sets of scrapers being respectively fitted against both sides of the screen frame.

[0006] As a further preferred embodiment of this technical solution, both sets of screen frames are provided with slots, and two sets of symmetrically distributed card frames are slidably installed in the mounting frame. Both sets of card frames are movably engaged with the screen frame through the slots. Telescopic tubes are provided between the two sets of card frames and the mounting frame, and the two ends of the telescopic tubes are respectively set with the mounting frame and the card frames.

[0007] As a further preferred embodiment of this technical solution, the mounting frame is provided with a bidirectional screw, the two ends of which pass through the mounting frame and are rotatably connected to the mounting frame through rolling bearings. The two ends of the bidirectional screw pass through two sets of retaining frames and are threadedly connected to the two sets of retaining frames respectively.

[0008] As a further preferred embodiment of this technical solution, a drain pipe is fixedly installed on the mounting bracket, the drain pipe is correspondingly arranged with the condenser pipe, and the lower end of the condenser pipe is fixedly connected to the mounting bracket.

[0009] As a further preferred embodiment of this technical solution, two sets of symmetrically distributed slide rods are fixedly installed inside the mounting frame. The movable seat is slidably sleeved with the slide rods. Two sets of symmetrically distributed springs are sleeved on the slide rods. The two ends of the two sets of springs are respectively fixedly connected to the movable seat and the mounting frame. A cam is rotatably installed on the mounting frame, and the cam is fitted with the movable seat.

[0010] As a further preferred embodiment of this technical solution, both sets of scrapers are rotatably connected to the movable seat via a rotating rod.

[0012] This utility model provides a corrosion-resistant vacuum system condensation device, which has the following beneficial effects: This invention utilizes a built-in rotatable dual-station screen frame to directly intercept solid particles in the condensate, effectively preventing them from entering downstream vacuum pumps, valves, pipelines, or recovery systems. This significantly reduces mechanical wear, seal failure, and the risk of secondary corrosion caused by particles, extending equipment lifespan. A cylinder-driven rack and pinion mechanism allows for easy rotation of the mounting plate, enabling the two screen frames to work alternately. When one set of screens needs cleaning or replacement, it can be quickly switched to the other set without interrupting the vacuum system, greatly improving production efficiency.

[0013] The scrapers on both sides of the screen frame of this utility model can slide back and forth along the screen surface under the drive of the moving seat and cam mechanism, automatically scraping away the accumulated solid impurities, maintaining the screen's permeability, extending the single use time, and reducing manual intervention. Furthermore, the scrapers can vibrate left and right in the mounting frame under the drive of the moving seat, shaking off the impurities cleaned from the screen frame, improving the cleaning efficiency of the screen frame. After the screen frame with adhering impurities is completed, the motor in the mounting frame is started to drive the cam to rotate. The cam is fitted against the moving seat, so during the cam rotation, the moving seat is pushed to slide on the mounting frame and the slide rod. The spring on the slide rod enables the moving seat to drive the two sets of scrapers to slide back and forth on the mounting frame. The motor in the moving seat drives the fly disc to rotate, which, in conjunction with the connecting rod, causes the second rack to slide back and forth in the moving seat. The second gear, in conjunction with the rotating rod, causes the two sets of scrapers to swing back and forth on the moving seat, effectively cleaning the impurities adhering to the surface of the screen frame.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides a technical solution: such as Figure 1 and Figure 2As shown in this embodiment, a corrosion-resistant vacuum system condensation device includes a mounting box 1. A condenser pipe 2 is fixedly installed inside the mounting box 1. A mounting frame 3 is fixedly installed below the mounting box 1. A mounting plate 5 is provided on the mounting frame 3. Two sets of symmetrically distributed screen frames 6 are embedded in the mounting plate 5. The screen frames 6 are located between the condenser pipe 2 and the drain pipe 4.

A first rack 9 is slidably installed inside the mounting frame 3. A cylinder 10 is fixedly installed inside the frame 3. The first rack 9 is meshed with the first gear 8. The first rack 9 is fixedly connected to the output end of the piston rod of the cylinder 10. A movable seat 14 is slidably installed on the mounting frame 3. Two sets of symmetrically distributed scrapers 18 are rotatably installed inside the movable seat 14. The two sets of scrapers 18 are located on both sides of the mounting plate 5. The two sets of scrapers 18 are respectively fitted to both sides of the screen frame 6. Each set of screen frames 6 has a slot 7. Two sets of symmetrically distributed slots are slidably installed inside the mounting frame 3. Frame 11, both sets of the clamping frames 11 are movably engaged with the screen frame 6 via clamping grooves 7. Telescopic tubes 12 are provided between each set of clamping frames 11 and the mounting frame 3. The two ends of the telescopic tubes 12 are respectively positioned corresponding to the mounting frame 3 and the clamping frames 11. A bidirectional screw 13 is provided inside the mounting frame 3. The two ends of the bidirectional screw 13 pass through the mounting frame 3 and are rotatably connected to the mounting frame 3 via rolling bearings. The two ends of the bidirectional screw 13 pass through the two sets of clamping frames 11 and are threadedly connected to the two sets of clamping frames 11 respectively. A fixed mounting bracket is mounted on the mounting frame 3. Equipped with a drain pipe 4, which corresponds to the condenser pipe 2, and the lower end of the condenser pipe 2 is fixedly connected to the mounting frame 3, the device directly intercepts solid particles in the condensate through a built-in rotatable dual-position screen frame 6. This effectively prevents them from entering downstream vacuum pumps, valves, pipelines, or recovery systems with the liquid, significantly reducing the risk of mechanical wear, seal failure, and secondary corrosion caused by particles, thus extending the equipment's service life. The mounting plate 5 can be easily rotated via a rack and pinion mechanism driven by a cylinder 10, allowing the two sets of screen frames 6 to work alternately. When one set of screens needs cleaning or replacement, it can be quickly switched to the other set without interrupting the vacuum system, greatly improving production efficiency.

[0018] like Figure 3 and Figure 4As shown, two sets of symmetrically distributed slide rods 15 are fixedly installed inside the mounting frame 3. The movable seat 14 is slidably sleeved with the slide rods 15. Two sets of symmetrically distributed springs 16 are sleeved on the slide rods 15. The two ends of the two sets of springs 16 are respectively fixedly connected to the movable seat 14 and the mounting frame 3. A cam 17 is rotatably installed on the mounting frame 3. The cam 17 is fitted against the movable seat 14. Both sets of scraper brushes 18 are rotatably connected to the movable seat 14 through rotating rods 19. A second gear 20 is sleeved on the rotating rods 19. A second rack 21 is slidably installed inside the movable base 14, and a flying disc 23 is rotatably installed inside the movable base 14. The second rack 21 is meshed with a second gear 20. A connecting rod 22 is rotatably installed on the second rack 21. The end of the connecting rod 22 away from the second rack 21 is rotatably connected to the flying disc 23 via a rotating shaft. Scraper brushes 18, located on both sides of the screen frame 6, can slide back and forth along the screen surface under the drive of the movable base 14 and the cam 17 mechanism, automatically scraping away accumulated solid impurities, maintaining the screen's permeability, extending the single-use time, and reducing manual intervention. Furthermore, the scraper brushes 18 can vibrate left and right in the mounting frame 3 under the drive of the movable base 14, shaking off the impurities cleaned from the screen frame 6. To improve the cleaning efficiency of the screen frame 6, after the screen frame 6 with adhering impurities is converted, the motor in the mounting frame 3 is started to drive the cam 17 to rotate. The cam 17 is set in close contact with the moving seat 14. Therefore, during the rotation of the cam 17, the moving seat 14 is pushed to slide on the mounting frame 3 and the slide rod 15. With the help of the spring 16 on the slide rod 15, the moving seat 14 drives the two sets of scrapers 18 to slide back and forth on the mounting frame 3. The motor in the moving seat 14 drives the fly disk 23 to rotate. With the help of the connecting rod 22, the second rack 21 slides back and forth in the moving seat 14. With the help of the second gear 20, the rotating rod 19 drives the two sets of scrapers 18 to swing back and forth on the moving seat 14, thus completing the effective cleaning of the impurities adhering to the surface of the screen frame 6.

[0019] This utility model provides a corrosion-resistant vacuum system condensation device. The specific working principle is as follows: by using a rotatable dual-position screen frame 6 built into the device, solid particles in the condensate are directly intercepted, effectively preventing them from entering the downstream vacuum pump, valve, pipeline or recovery system with the liquid. This significantly reduces mechanical wear, sealing failure and the risk of secondary corrosion caused by particles, and extends the service life of the equipment. The mounting plate 5 can be easily rotated by the cylinder 10 driving the rack and pinion mechanism, so that the two sets of screen frames 6 work alternately. When a set of screens needs cleaning or replacement, it can be quickly switched to another set without interrupting the vacuum system, greatly improving production efficiency. The scrapers 18, located on both sides of the screen frame 6, slide back and forth along the screen surface under the drive of the moving base 14 and cam 17 mechanism, automatically scraping away accumulated solid impurities, maintaining screen permeability, extending single-use time, and reducing manual intervention. Furthermore, the scrapers 18, driven by the moving base 14, can vibrate left and right within the mounting frame 3, shaking off impurities cleaned from the screen frame 6, improving the cleaning efficiency of the screen frame 6. After completing the conversion of the screen frame 6 with adhering impurities, the system is activated. The motor inside the mounting bracket 3 drives the cam 17 to rotate. The cam 17 is fitted with the movable seat 14. Therefore, during the rotation of the cam 17, the movable seat 14 is pushed to slide on the mounting bracket 3 and the slide rod 15. With the help of the spring 16 on the slide rod 15, the movable seat 14 drives the two sets of scraper brushes 18 to slide back and forth on the mounting bracket 3. The motor in the movable seat 14 drives the fly disk 23 to rotate. With the help of the connecting rod 22, the second rack 21 slides back and forth in the movable seat 14. With the help of the second gear 20, the rotating rod 19 drives the two sets of scraper brushes 18 to swing back and forth on the movable seat 14, thus effectively cleaning the impurities attached to the surface of the screen frame 6.
