The control plate 5 is slidably disposed in the control groove 6 and fixedly connected to one side of the locking frame 9. The sealing ring 7 is detachably disposed inside the fixed pipe 2. The locking groove 8 is opened on the outside of the connecting pipe 3. One end of the locking frame 9 passes through the fixed pipe 2. The fixed tube 2 is inserted into the locking groove 8. A limiting mechanism is provided on the outside of the fixed tube 2. The limiting mechanism includes a movable plate 10, a linkage plate 11, a linkage block 12, an adapter plate 13, an adapter 14, an adapter groove 15, an adapter rod 16, and a linkage groove 17.

The adapter plate 13 is fixedly connected to one side of the adapter 14. The adapter 14 is slidably sleeved on the outside of the fixed tube 2. Multiple adapter rods 16 are slidably installed on the side wall of the control sleeve 4. Multiple adapter grooves 15 are opened on the outer wall of the fixed tube 2, and one end of the adapter rod 16 is inserted into the adapter groove 15.

[0032] The heat exchange device includes a flow tube 18, a heat exchange tube 19, and heat exchange plates 20. The flow tube 18 is detachably installed inside the heat exchange box 1. The heat exchange tube 19 passes through the flow tube 18, and the diameter of the heat exchange tube 19 is smaller than the diameter of the flow tube 18. Multiple heat exchange plates 20 are detachably arranged outside the heat exchange tube 19. The inlet end of the flow tube 18 is detachably connected to one of the fixed tubes 2, and the outlet end of the flow tube 18 is located in the heat exchange box 1.

[0033] The top of the heat exchange box 1 is detachably provided with a box cover 21. The top of the box cover 21 is fixedly connected with an exhaust pipe 22 and an air inlet pipe 23. The bottom end of the air inlet pipe 23 is connected to the input end of the heat exchange tube 19.

[0034] A protective cover 24 is provided on the outside of the output end of the heat exchange tube 19.

[0035] In this embodiment, when the device is needed, it is first connected to the output end of the delivery pump via the connecting pipe 3 in the quick-release device on the left side of the exchange box 1. Then, the connecting pipe 3 in the quick-release device on the right side of the exchange box 1 is connected to the input end of another delivery pump. Next, the air inlet pipe 23 is connected to the external air inlet device. Then, cold water is drawn out by the delivery pump on the right side and transported to the fixed pipe 2 via the connecting pipe 3 connected to the output end of the delivery pump. The cold water then enters the flow pipe 18 in the exchange box 1, while the external air inlet device delivers hot air to the air inlet pipe 23, which then enters the heat exchange pipe 19. The cold water in the flow pipe 18 first undergoes preliminary heat exchange with the hot air flowing through the heat exchange pipe 19, which passes through the flow pipe 18. To improve heat exchange efficiency, the water that has undergone preliminary heat exchange in the flow tube 18 flows into the exchange tank 1 through the flow tube 18. Then, the heat exchange plate 20 set on the outside of the heat exchange tube 19 increases the heat exchange area, so that the heat of the hot air in the heat exchange tube 19 exchanges heat with the water in the exchange tank 1 through the heat exchange plate 20. The hot air will eventually enter the exchange tank 1 through the output end of the heat exchange tube 19 and mix with the water in the exchange tank 1. The protective cover 24 can prevent water from flowing back into the heat exchange tube 19 to a certain extent. Then, the gas and water mix to achieve sufficient heat exchange. Then, the hot air after heat exchange becomes cold air and is finally discharged from the exhaust pipe 22 set on the tank cover 21. Then, the cold water after heat exchange becomes hot water. Then, the hot water is extracted by the external transfer pump on the right side of the exchange tank 1 and transported to the subsequent storage equipment.

[0036] Please see Figure 4 and Figure 5 As a further implementation of the overall device: the end of the adapter rod 16 and the edge of the inner wall of the adapter groove 15 are designed with rounded corners.

[0037] An adapter spring 25 is provided on the outside of the control sleeve 4. One end of the adapter spring 25 is connected to the outer wall of the control sleeve 4. A linkage spring 26 is connected to one side of the adapter sleeve 14. The other end of the linkage spring 26 is in contact with the linkage plate 11.

[0038] The lower end of the inner wall of the locking groove 8 adopts a chamfered structure design.

[0039] Multiple sealing strips 27 are provided on the outside of the connecting pipe 3, and multiple sealing grooves 28 are correspondingly provided in the fixed pipe 2. The sealing strips 27 are engaged in the corresponding sealing grooves 28, and both the sealing strips 27 and the sealing rings 7 are made of rubber.

[0040] More specifically, when pipeline maintenance and cleaning are required, first stop the equipment operation and drain the water from the exchange tank 1. Then, first rotate the movable plate 10, causing it to move the linkage groove 17. When the linkage groove 17 moves to the position corresponding to the linkage plate 11, push the adapter 14, causing it to slide through the adapter plate 13, thus moving the linkage plate 11 and the linkage block 12. This allows the linkage block 12 to pass into the linkage groove 17. Simultaneously, the adapter 14 and the movable plate 10 work together to compress the linkage spring 26. When the linkage spring 26 is compressed to its limit, the linkage block 12 just completely passes through the linkage groove 17 and moves to the other side of the movable plate 10. At this point, continue rotating the movable plate 10, causing it to move the linkage groove 17 to... The position is not corresponding to the linkage block 12 and linkage plate 11. At this time, the linkage block 12 and adapter plate 13 cooperate to limit the adapter 14 to one side of the movable plate 10, and the adapter 14 no longer limits the adapter rod 16. Then, the control sleeve 4 is rotated in the forward direction. The control sleeve 4 will drive the multiple adapter rods 16 that are slidably set on the side wall to move. Then, the inner wall of the adapter groove 15 presses against one end of the adapter rod 16. Due to the rounded corner design at the edge of the adapter rod 16 and the inner wall of the adapter groove 15, one end of the adapter rod 16 slides out of the adapter groove 15, and the other end of the adapter rod 16 drives the adapter spring 25 to stretch. At the same time, the control sleeve 4 will drive the control groove 6 opened on the inner side to rotate in the forward direction. Due to the variable diameter design of the control groove 6 and the control plate 5, the control plate 5 will drive the locking frame 9 to move outward, so that the locking frame 9 can be locked outward. The other end of the retaining bracket 9 is pulled out from the retaining groove 8, and then the connecting pipe 3 is pulled out from the fixed pipe 2. The pipe is then cleaned or replaced. After cleaning or replacement, the corresponding connecting pipe 3 is reinserted into the fixed pipe 2, so that one end of the connecting pipe 3 abuts against the sealing ring 7. Then, the control sleeve 4 is rotated in the reverse direction, causing the control groove 6 to rotate in the reverse direction. The retaining bracket 9 is then reset through the cooperation of the control groove 6 and the control plate 5, allowing one end of the retaining bracket 9 to be reinserted into the retaining groove 8. Due to the chamfered design at the bottom of the inner wall of the retaining groove 8, when the retaining bracket 9 is fully inserted into the retaining groove 8, the retaining bracket 9, through its cooperation with the retaining groove 8, causes the connecting pipe 3 to press against the sealing ring 7, and the multi-ring sealing strip 27 on the outside of the connecting pipe 3 simultaneously engages. The fitting is inserted into the sealing groove 28 in the fixed tube 2, achieving quick connection while ensuring the seal at the connection point. At this time, the adapter spring 25 drives the adapter rod 16 to reset and slide into the original adapter groove 15. Then, the movable plate 10 is rotated again, causing the movable plate 10 to drive the linkage groove 17 to rotate to the position corresponding to the linkage block 12. At this time, the linkage spring 26 pushes the adapter 14 to slide and reset. Then, the adapter 14 will drive the linkage plate 11 and the linkage block 12 to slide and reset through the adapter plate 13. When the linkage spring 26 is fully reset, the linkage plate 11 and the linkage block 12 are exactly on both sides of the movable plate 10. At this time, the movable plate 10 is rotated again, causing the movable plate 10 to drive the linkage groove 17 to move to a position that does not correspond to the linkage plate 11 and the linkage block 12.At this point, the linkage plate 11, linkage block 12, and adapter plate 13, together with the movable plate 10, support the adapter 14. Combined with the preload applied by the linkage spring 26, this prevents the adapter 14 from easily sliding. Then, the inner wall of the adapter 14 again limits the outer end of the adapter rod 16, preventing it from moving. Finally, the adapter rod 16 and the adapter groove 15 work together to lock and restrict the control sleeve 4, preventing it from rotating. This ensures the structural stability after connection and guarantees stable operation of the equipment.

[0041] In summary, when using or operating the entire equipment: First, connect the connecting pipe 3 in the quick-release device on the left side of the exchange box 1 to the output end of the delivery pump. Then, connect the connecting pipe 3 in the quick-release device on the right side of the exchange box 1 to the input end of another delivery pump. Next, connect the air inlet pipe 23 to the external air inlet device. Then, the delivery pump on the right side draws out cold water, which is then transported to the fixed pipe 2 through the connecting pipe 3 connected to the output end of the delivery pump. The cold water then enters the flow pipe 18 in the exchange box 1. Simultaneously, the external air inlet device delivers hot air to the air inlet pipe 23, which then enters the heat exchange tube 19. The cold water in the flow pipe 18 first undergoes preliminary heating with the hot air flowing through the heat exchange tube 19. The heat exchange process initially improves heat exchange efficiency. Water that has undergone initial heat exchange in the flow tube 18 flows into the exchange tank 1 through the flow tube 18. The heat exchange plate 20 on the outside of the heat exchange tube 19 increases the heat exchange area, allowing the heat of the hot air in the heat exchange tube 19 to exchange with the water in the exchange tank 1 through the heat exchange plate 20. The hot air eventually enters the exchange tank 1 through the output end of the heat exchange tube 19 and mixes with the water in the exchange tank 1. The protective cover 24 can prevent water from flowing back into the heat exchange tube 19 to a certain extent. Then, the gas and water mix to achieve sufficient heat exchange. The hot air after heat exchange becomes cold air and is finally discharged from the exhaust pipe 22 on the tank cover 21. The cold water after heat exchange becomes hot water and is then extracted by the external transfer pump on the right side of the exchange tank 1 and transported to the subsequent storage equipment.

[0042] When pipeline maintenance and cleaning are required, first stop the equipment operation and drain the water from the exchange tank 1. Then, first rotate the movable plate 10, causing it to move the linkage groove 17. When the linkage groove 17 moves to the position corresponding to the linkage plate 11, push the adapter 14, causing it to slide through the adapter plate 13, thus causing the linkage plate 11 and the linkage block 12 to slide and the linkage block 12 to pass into the linkage groove 17. At the same time, the adapter 14 and the movable plate 10 will cooperate to compress the linkage spring 26. When the linkage spring 26 is compressed to its limit, the linkage block 12 will just completely pass through the linkage groove 17 and move to the other side of the movable plate 10. At this time, continue to rotate the movable plate 10, causing it to move the linkage groove 17 to a position where it is no longer in contact with the linkage plate 11. The positions corresponding to the moving block 12 and the linkage plate 11 are such that the linkage block 12 and the adapter plate 13 cooperate to limit the adapter 14 to one side of the moving plate 10, and the adapter 14 no longer limits the adapter rod 16. Then, the control sleeve 4 is rotated forward, and the control sleeve 4 will drive the multiple adapter rods 16 that are slidably set on the side wall to move. Then, the inner wall of the adapter groove 15 presses against one end of the adapter rod 16. Due to the rounded corner design at the edge of the adapter rod 16 and the inner wall of the adapter groove 15, one end of the adapter rod 16 slides out of the adapter groove 15, and the other end of the adapter rod 16 drives the adapter spring 25 to stretch. At the same time, the control sleeve 4 will drive the control groove 6 opened on the inner side to rotate forward. Due to the variable diameter design of the control groove 6 and the control plate 5, the control plate 5 will drive the locking frame 9 to move outward, so that the locking frame 9. Pull the other end out of the locking groove 8, then pull the connecting pipe 3 out of the fixed pipe 2, and then clean or replace the pipe. After cleaning or replacement, reinsert the corresponding connecting pipe 3 into the fixed pipe 2, so that one end of the connecting pipe 3 abuts against the sealing ring 7, and then rotate the control sleeve 4 in the opposite direction, so that the control sleeve 4 drives the control groove 6 to rotate in the opposite direction. Then, through the cooperation of the control groove 6 and the control plate 5, the locking bracket 9 is reset, so that one end of the locking bracket 9 is reinserted into the locking groove 8. Due to the chamfer design of the bottom of the inner wall of the locking groove 8, when the locking bracket 9 is fully inserted into the locking groove 8, the locking bracket 9, through the cooperation with the locking groove 8, drives the connecting pipe 3 to press the sealing ring 7, and the multi-ring sealing strip 27 set on the outside of the connecting pipe 3 is simultaneously locked in. The connection is made quickly into the sealing groove 28 in the fixed tube 2, ensuring a tight seal at the connection point. At this time, the adapter spring 25 drives the adapter rod 16 to reset and slide into the original adapter groove 15. Then, the movable plate 10 is rotated again, causing the movable plate 10 to drive the linkage groove 17 to rotate to the position corresponding to the linkage block 12. At this point, the linkage spring 26 pushes the adapter 14 to slide back to its original position. Then, the adapter 14, through the adapter plate 13, drives the linkage plate 11 and linkage block 12 to slide back to their original positions. When the linkage spring 26 has fully reset, the linkage plate 11 and linkage block 12 are exactly on opposite sides of the movable plate 10. At this point, the movable plate 10 is rotated again, causing the movable plate 10 to drive the linkage groove 17 to move to a position that does not correspond to the linkage plate 11 and linkage block 12.At this point, the linkage plate 11, linkage block 12, and adapter plate 13, together with the movable plate 10, support the adapter 14. Combined with the preload applied by the linkage spring 26, this prevents the adapter 14 from easily sliding. Then, the inner wall of the adapter 14 again limits the outer end of the adapter rod 16, preventing it from moving. Finally, the adapter rod 16 and the adapter groove 15 work together to lock and restrict the control sleeve 4, preventing it from rotating. This ensures the structural stability after connection and guarantees stable operation of the equipment.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
