Description

Technical Field

[0001] The present invention relates to the technical field of air compressors, and particularly to a heat exchange device for high-temperature gases at the rear end of a cylinder. Background Art

[0002] With the continuous progress of industrial technology, reciprocating piston compressors, as important equipment for gas compression, have been widely used in multiple industries such as chemical engineering, energy, and manufacturing. Such compressors mainly achieve gas compression through the reciprocating motion of pistons in cylinders. However, the high-temperature gases generated during this process may not only damage the components of the compressor itself but also affect the normal operation of downstream systems. To solve these problems, the traditional approach is to use a combination of copper tubes and a water circulation system to exchange heat and cool down the high-temperature gases discharged from the rear end of the cylinder.

[0003] Specifically, this kind of heat exchange device usually consists of a box body and copper tubes installed inside. The high-temperature gases pass through these copper tubes, while the cooling water flows inside the box body to absorb and carry away the heat of the high-temperature gases in the copper tubes. Although this method can effectively reduce the gas temperature to a certain extent, protect the equipment from high temperatures, and maintain the stable operation of downstream systems, there are still some problems in the long-term use process.

[0004] First of all, dust in the air and oil stains generated during the operation of the compressor will accumulate on the inner wall of the copper tubes over time, forming deposits that are difficult to remove. This layer of deposits will hinder the heat transfer efficiency, resulting in a significant decline in the performance of the heat exchange device originally designed for efficient heat dissipation. In the face of this situation, the traditional method is to disassemble the copper tubes and use high-pressure water flow to wash away the deposits. However, this method is complex to operate, and for those firmly attached oil stains and dust, the cleaning effect is not ideal. To further solve the problem, special chemical cleaning agents are usually needed to assist in cleaning. Although chemical cleaning agents can partially remove stubborn stains, they often contain strongly corrosive components, which will cause irreversible corrosion to the inner wall of the copper tubes in the long-term use. Once corrosion occurs, it is necessary to regularly detect the change in the inner wall thickness of the copper tubes. When the corrosion depth exceeds 3 millimeters, the corresponding copper tube components must be replaced, which will increase the maintenance cost and downtime. Summary of the Invention

[0005] In view of this, the present invention provides a heat exchange device for high-temperature gases at the rear end of a cylinder, which can overcome the disadvantages that when the existing heat exchange device is in use, deposits that are difficult to remove will form on the inner wall of the copper tubes, thereby hindering the heat transfer efficiency, usually requiring disassembly and cleaning, which is troublesome to operate, and may require the assistance of special chemical cleaning agents, resulting in corrosion of the copper tubes and the need for replacement.

Two water pumps are installed on the side of the water tank. The two ends of the infusion pipe are respectively connected to the water pump and the connecting plate, and the water pump is kept in communication with the inside of the rotating shaft of the winding wheel. The two ends of the drain pipe are respectively connected to the front water pump and the waste liquid tank and kept in communication. The two ends of the liquid extraction pipe are respectively connected to the rear water pump and the liquid storage tank and kept in communication.

[0010] In one embodiment, the plugging assembly includes an aggregate frame, a sewage pipe, a valve, a connecting rod, a rotating block, a rubber plate, a servo motor, and a full gear. The aggregate frame is connected to the top of the base. The sewage pipe is connected to the side of the aggregate frame and kept in communication. The valve is installed on the sewage pipe. The connecting rods are symmetrically connected to the other ends of the copper pipes. The rotating block is rotatably connected to the connecting rods.

[0011] In one embodiment, it further includes a mounting frame, a brush roller, a worm gear, a second drive motor, a worm, and a flushing mechanism.

Through the synergistic effect of the first rubber ball, the second rubber ball, the first spray head, the moving component, and the water supply component, the present invention can realize the automatic cleaning of the inside of the copper pipe. Specifically, when the inside of the copper pipe needs to be cleaned, the moving component can drive the first rubber ball and the second rubber ball to move inside the copper pipe. At the same time, the water supply component conveys water to the first spray head to flush the inner wall of the copper pipe. This design can avoid the complex operation of the traditional disassembly and cleaning method, improve the cleaning efficiency, and prevent the corrosion problem of the copper pipe caused by the use of chemical cleaning agents.

[0015] 2. During the movement of the first rubber ball and the second rubber ball of the present invention along the inner wall of the copper pipe, due to their elastic properties, they can closely adhere to the inner wall of the copper pipe. They can not only push the sediment to concentrate at the front end, but also use the water flow ejected from the first nozzle to remove stubborn sediment. In addition, the designs of the sliding pipe, the first magnetic ring, and the second magnetic ring can further ensure that sediment will not enter the intake pipe or the exhaust pipe during the cleaning process. This combined design can greatly improve the long-term operation stability of the heat exchange device and reduce the problem of the decrease in heat transfer efficiency caused by sediment.

[0016] 3. Through the action of the blocking component of the present invention, the front end of the copper pipe can be conveniently opened and closed. While not affecting the heat exchange work of high-temperature gas, it is convenient for the sediment in the copper pipe to be discharged. And through the cooperation of the brush roller, the worm gear, the worm, and the flushing mechanism, the outer walls of the first rubber ball and the first connecting pipe can be automatically cleaned, and the waste water can directly fall into the aggregate frame for unified discharge, which is both convenient and environmentally friendly. There is no need to worry about environmental pollution problems caused by improper waste water treatment. This series of designs can greatly simplify the equipment maintenance process and reduce the operation cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] As Figure 3 and Figure 4As shown, the moving component includes a first connecting pipe 12, a second connecting pipe 13, a connecting plate 14, a winding wheel 15, a first driving motor 16, and a guiding mechanism. The left side of the first rubber ball 8 is connected to the first connecting pipe 12, and the right end of the first connecting pipe 12 is in communication with the passage 801 on the first rubber ball 8. The first connecting pipe 12 passes through the inside of the copper pipe 4. The right side of the second rubber ball 10 is connected to the second connecting pipe 13, and the left end of the second connecting pipe 13 is in communication with the inside of the second rubber ball 10. Two connecting plates 14 are connected to the front and back sides of the right side of the water tank 2. A winding wheel 15 is rotatably connected between the two connecting plates 14, and the inside of the rotating shaft of the winding wheel 15 is hollow. The first connecting pipe 12 is wound around the front winding wheel 15, and the second connecting pipe 13 is wound around the rear winding wheel 15. One ends of the first connecting pipe 12 and the second connecting pipe 13 are respectively in communication with the inside of the rotating shaft of the winding wheel 15. The first driving motors 16 are installed on the frontmost and rearmost connecting plates 14. The number of the first driving motors 16 is two, and the output shafts of the two first driving motors 16 are respectively connected to the rotating shafts of the two winding wheels 15. The guiding mechanism is used to guide the first connecting pipe 12 and the second connecting pipe 13; the guiding mechanism includes a support rod 17 and a roller 18. Support rods 17 are connected to the right sides of the frontmost and rearmost connecting plates 14. Two rollers 18 are rotatably connected to the two support rods 17 symmetrically up and down, and the first connecting pipe 12 and the second connecting pipe 13 respectively bypass the two rollers 18 on the front and back sides.

[0033] As Figure 5 and Figure 6 shown, the water supply component includes a liquid storage tank 19, a waste liquid tank 20, a water pump 21, an infusion pipe 2101, a drain pipe 22, and a liquid extraction pipe 23. The liquid storage tank 19 and the waste liquid tank 20 are placed on the top of the base 1, and both the liquid storage tank 19 and the waste liquid tank 20 are located inside the fixed shell 3. Two water pumps 21 are installed on the right side of the water tank 2. An infusion pipe 2101 is connected between the liquid inlet of the front water pump 21 and the second connecting plate 14 from front to back. An infusion pipe 2101 is also connected between the liquid outlet of the rear water pump 21 and the third connecting plate 14 from front to back. The end of the infusion pipe 2101 away from the water pump 21 is in communication with the inside of the rotating shaft of the winding wheel 15. A drain pipe 22 is connected and in communication at the liquid outlet of the front water pump 21. The end of the drain pipe 22 away from the front water pump 21 is threadedly connected and in communication with the top of the waste liquid tank 20. A liquid extraction pipe 23 is connected and in communication at the liquid inlet of the rear water pump 21. The end of the liquid extraction pipe 23 away from the rear water pump 21 is threadedly connected and in communication with the top of the liquid storage tank 19.

[0034] As Figure 7 and Figure 8As shown in the figure, the plugging assembly includes an aggregate frame 24, a sewage discharge pipe 25, a valve 26, a connecting rod 27, a rotating block 28, a rubber plate 29, a servo motor 30 and a full gear 31. The aggregate frame 24 is connected to the upper right front side of the base 1. The lower part of the front side of the aggregate frame 24 is connected to the sewage discharge pipe 25 to keep it connected. A valve 26 is installed on the sewage discharge pipe 25. Both the top and the bottom of the front end of the copper pipe 4 are connected to a connecting rod 27. A rotating block 28 is rotatably connected to each of the two connecting rods 27. A rubber plate 29 is connected to each of the two rotating blocks 28. The rubber plate 29 is in a semi-circular shape, and the two rubber plates 29 can form a complete circle when they contact each other and block the front end of the copper pipe 4. A semi-circular hole is opened on each of the two sides of the rubber plates 29 that are close to each other. When the two rubber plates 29 contact each other, the two semi-circular holes can form a circular hole, and the first connecting pipe 12 passes through the above-mentioned circular hole. The servo motor 30 is installed on the left part of the rear side of the aggregate frame 24. The rear ends of the rotating shafts of the two rotating blocks 28 are both connected to a full gear 31. The lower full gear 31 is connected to the output shaft of the servo motor 30, and the two full gears 31 mesh with each other.

[0035] In the initial state, a certain amount of water is contained inside both the water tank 2 and the liquid storage tank 19. The front and rear sides of the copper tube 4 are blocked by a rubber plate 29 and a first rubber ball 8 respectively. When it is necessary to exchange heat and cool down the high-temperature gas at the rear end of the cylinder, first, the high-temperature gas is introduced into the copper tube 4 through the intake pipe 5. At the same time, the water in the water tank 2 is driven to flow by the water circulation system. The water in the water tank 2 can exchange heat with the high-temperature gas in the copper tube 4 to cool down the high-temperature gas in the copper tube 4, and the cooled gas can be discharged through the outlet pipe 6.When it is necessary to clean the inside of the copper tube 4, first, high-temperature gas is no longer introduced into the copper tube 4. Then, the servo motor 30 drives the lower full gear 31 to rotate, which can drive the upper full gear 31 to rotate. The full gear 31 can drive the rotating block 28 to rotate, and the rotating block 28 can drive the rubber plates 29 on the upper and lower sides to rotate and open towards the side away from each other, so that the rubber plates 29 no longer block the front end of the copper tube 4. Then, the first driving motor 16 drives the winding wheel 15 to rotate, so that the front winding wheel 15 can wind the first connecting pipe 12, and the rear winding wheel 15 can unwind the second connecting pipe 13. The first connecting pipe 12 can pull the first rubber ball 8 into the inside of the copper tube 4 from the rear end of the copper tube 4. The first rubber ball 8 can pull the second rubber ball 10, the first spray head 11 and the second connecting pipe 13 into the inside of the copper tube 4 through the pull rope 9. The roller 18 can guide and limit the first connecting pipe 12 and the second connecting pipe 13. The first rubber ball 8 and the second rubber ball 10 can closely adhere to the inner wall of the copper tube 4 by their own elasticity. And during the process of the first rubber ball 8 moving along the inside of the copper tube 4, the first rubber ball 8 can push the sediment on the inner wall of the copper tube 4 towards the front end of the copper tube 4, achieving the purpose of initially cleaning the inner wall of the copper tube 4. At the same time, the water pump 21 can be started. The rear water pump 21 can extract the water in the liquid storage tank 19 through the liquid extraction pipe 23, and through the rear liquid delivery pipe 2101, the rear winding wheel 15, the second connecting pipe 13 and the second rubber ball 10, the water can be conveyed to the first spray head 11, so that the first spray head 11 sprays water to wash the inner wall of the copper tube 4, thereby being able to remove the relatively stubborn sediment on the inner wall of the copper tube 4. Since both the first rubber ball 8 and the second rubber ball 10 closely adhere to the inner wall of the copper tube 4, the waste water generated by washing the inner wall of the copper tube 4 will be concentrated between the first rubber ball 8 and the second rubber ball 10 and enter the inside of the first rubber ball 8 through the channel 801. At the same time, the front water pump 21 can extract the waste water inside the first rubber ball 8 through the front liquid delivery pipe 2101, the front winding wheel 15 and the first connecting pipe 12, and can convey the waste water to the waste liquid tank 20 through the drain pipe 22 for collection. When the first rubber ball 8 is pulled out from the front end of the copper tube 4, the sediment inside the copper tube 4 can be pushed down into the aggregate frame 24 for collection, which is convenient for subsequent unified treatment. Then, the water pump 21 is turned off, and the first driving motor 16 drives the winding wheel 15 to reverse, so that the front winding wheel 15 can unwind the first connecting pipe 12, and the rear winding wheel 15 can wind the second connecting pipe 13, thereby being able to pull the first rubber ball 8 into the inside of the copper tube 4 from the front end of the copper tube 4 and move back to the installation cylinder 7 along the inside of the copper tube 4. Then, the servo motor 30 drives the lower full gear 31 to reverse, which can drive the rubber plates 29 on the upper and lower sides to rotate and close towards the side close to each other, so that the rubber plates 29 re-block the front end of the copper tube 4. In this way, the inner wall of the copper tube 4 can be automatically cleaned without disassembling the copper tube 4, and the effect of comprehensive cleaning can be achieved. There is no need to rely on special chemical cleaning agents for auxiliary cleaning, and the copper tube 4 can be prevented from being corroded;When the water in the liquid storage tank 19 is used up, the drain pipe 22 and the liquid suction pipe 23 can be unscrewed from the liquid storage tank 19 and the waste liquid tank 20 respectively. Then, the liquid storage tank 19 and the waste liquid tank 20 can be taken out, the liquid storage tank 19 can be refilled with water, and the waste water in the waste liquid tank 20 can be poured out for unified treatment. Finally, the liquid storage tank 19 and the waste liquid tank 20 are put back in place and reconnected to the drain pipe 22 and the liquid suction pipe 23 respectively.

[0036] As Figure 9 shown, it further includes an installation frame 32, a brush roller 33, a worm gear 34, a second drive motor 35, a worm 36 and a flushing mechanism. The right side of the top of the aggregate frame 24 is connected with an installation frame 32, and the first connecting pipe 12 slides through the left and right sides of the installation frame 32. A hole is opened on the left side of the installation frame 32 for the first rubber ball 8 to pass through. The brush rollers 33 are symmetrically and rotatably connected to the front and back inside the installation frame 32. The first connecting pipe 12 can pass between the two brush rollers 33. The right parts of the two brush rollers 33 are both connected with worm gears 34. The second drive motor 35 is installed on the right part of the rear side of the aggregate frame 24. A worm 36 is connected to the output shaft of the second drive motor 35, and both worm gears 34 are meshed with the worm 36. The flushing mechanism is used to flush the part of the first connecting pipe 12 located inside the installation frame 32; the flushing mechanism includes a second spray head 37 and a water supply pipe 38. The second spray heads 37 are symmetrically installed on the left and right of the top of the installation frame 32. A water supply pipe 38 is connected between the upper ends of the two second spray heads 37, and the rear end of the water supply pipe 38 is connected and kept in communication with the rear liquid delivery pipe 2101.

[0037] When the front take-up wheel 15 winds up the first connecting pipe 12, the part of the first connecting pipe 12 located inside the copper pipe 4 will be gradually pulled out and gradually pass through the inside of the installation frame 32. At the same time, the rear liquid delivery pipe 2101 can transport part of the clear water pumped by the rear water pump 21 to the second spray head 37 through the water supply pipe 38, so that the second spray head 37 can spray water to flush the part of the first connecting pipe 12 located inside the installation frame 32, and the waste water will directly fall into the aggregate frame 24. At the same time, the second drive motor 35 can be used to drive the worm 36 to rotate, and the worm 36 can drive the worm gears 34 and the brush rollers 33 to rotate. The brush rollers 33 can brush and clean the outer wall of the first connecting pipe 12 during the flushing process of the first connecting pipe 12, improving the cleaning effect on the first connecting pipe 12. When the first rubber ball 8 is pulled out from the front end of the copper pipe 4, the first rubber ball 8 will also enter the installation frame 32 and contact the brush roller 33, so that the outer wall of the first rubber ball 8 can also be automatically cleaned. After the cleaning is completed, the valve 26 can be opened so that the waste water in the aggregate frame 24 can be discharged through the sewage pipe 25.

[0038] As Figures 10-12As shown in the figure, it further includes a sliding tube 39, a first magnetic ring 40 and a second magnetic ring 41. The inner parts of the front and rear ends of the copper tube 4 are both slidably connected with the sliding tube 39, and through holes 3901 are opened at the tops of the two sliding tubes 39. The through holes 3901 on the two sliding tubes 39 are respectively communicated with the air inlet pipe 5 and the air outlet pipe 6. The right end of the rear sliding tube 39 is connected with the first magnetic ring 40, and the left end of the front sliding tube 39 is also connected with the first magnetic ring 40. The second magnetic ring 41 is connected inside the first rubber ball 8.

[0039] When the first rubber ball 8 enters the inside of the copper tube 4 from the rear end of the copper tube 4, the first rubber ball 8 will drive the second magnetic ring 41 to move leftward and approach the first magnetic ring 40 at the rear. The second magnetic ring 41 can pull the first magnetic ring 40 at the rear to move leftward through magnetic force, and drive the rear sliding tube 39 to move leftward, so that the through hole 3901 on the rear sliding tube 39 is no longer communicated with the air inlet pipe 5, and the rear sliding tube 39 blocks the lower end of the air inlet pipe 5. In this way, when the first rubber ball 8 pushes the sediment on the inner wall of the copper tube 4 towards the front end of the copper tube 4, it can prevent the sediment from entering the air inlet pipe 5 through the through hole 3901 on the rear sliding tube 39, and can also prevent the water sprayed by the first nozzle 11 from entering the air inlet pipe 5. Similarly, when the first rubber ball 8 is about to be pulled out of the front end of the copper tube 4, the first rubber ball 8 can drive the first magnetic ring 40 and the front sliding tube 39 at the front to move rightward through the second magnetic ring 41, so that the front sliding tube 39 blocks the lower end of the air outlet pipe 6, thereby preventing sediment and water from entering the air outlet pipe 6. When the first rubber ball 8 moves back to the inside of the mounting cylinder 7 along the inside of the copper tube 4, the first rubber ball 8 can drive the two sliding tubes 39 to slide reversely and reset through the second magnetic ring 41, so that the through holes 3901 on the two sliding tubes 39 can be respectively re-communicated with the air inlet pipe 5 and the air outlet pipe 6.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
