[0032] In this embodiment, as Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 9As shown, four first openings 12 are provided on the side surface of the outer cylinder 10. A first rotating cylinder 14 is fixed to the top of the outer cylinder 10. The first rotating cylinder 14 extends into the groove 15. Four second openings 19 are provided on the side surface of the inner cylinder 18. A second rotating cylinder 20 is fixed to the top of the inner cylinder 18.

One end of the first spring 22 is fixed to the first slider 21. The first slider 21 is slidably connected in the first sliding groove 16. The first spring 22 acts to support the first slider 21. When the first slider 21 slides in the first sliding groove 16, the second rotating cylinder 20 rotates, thereby driving the inner cylinder 18 to rotate.

[0033] In this embodiment, as Figure 2 shown, a motor 23 is fixed inside the bottom of the tank body 1. The top of the motor 23 is connected to the stirring rod 24. The stirring rod 24 penetrates through the bottom of the outer cylinder 10, the bottom of the inner cylinder 18, and the second rotating cylinder 20 and is rotatably connected to the top of the groove 15. The stirring rod 24 can rotate under the action of the motor 23, facilitating the automatic stirring of the coolant and making the heat exchange effect more uniform.

[0034] In this embodiment, as Figure 2 、 Figure 7 、 Figure 8 and Figure 9 shown, the linkage rotation mechanism 26 penetrates through the inner wall of the first rotating cylinder 14 and is connected to the first slider 21. The linkage rotation mechanism 26 is snap-connected to the top of the outer cylinder 10. Two second sliding grooves 2604 are symmetrically provided on both sides of the first rotating cylinder 14. A movable ring 2605 is sleeved outside the first rotating cylinder 14. Two second sliders 2606 are symmetrically fixed on the two inner walls of the movable ring 2605. The second sliders 2606 are slidably connected in the second sliding grooves 2604. A first piston 2607 is fixed to the top of the second slider 2606. Two first oil storage cylinders 2608 are symmetrically fixed inside the two side walls of the first rotating cylinder 14. The upper side of the first piston 2607 is connected to the second piston 2610 through a second spring 2609. The first piston 2607 and the second piston 2610 are both slidably connected in the first oil storage cylinder 2608. When the lifting hook 2603 moves upward, it can lift the movable ring 2605 and the two second sliders 2606 upward. The first piston 2607, the second spring 2609, and the second piston 2610 move upward as a whole, facilitating the pressing out of the hydraulic oil above the second piston 2610. When the first piston 2607 moves upward to the top, the upward movement of the second slider 2606 can drive the first piston 2607 to continue moving upward. At this time, the second spring 2609 is compressed, facilitating the pressing out of the hydraulic oil between the first piston 2607 and the second piston 2610.

[0035] In this embodiment, asFigure 6 and Figure 8 As shown in Figure 8 , symmetrically fixed inside the two side walls of the first rotating cylinder 14 are second oil storage cylinders 2612, and the second oil storage cylinders 2612 are connected to the side of the top of the first oil storage cylinder 2608 through first connecting pipes 2611. A third piston 2613 is slidably connected inside the second oil storage cylinders 2612, and the third piston 2613 is fixed to one side of the first slider 21. The first connecting pipes 2611 serve to connect the first oil storage cylinder 2608 and the second oil storage cylinders 2612. When the first piston 2607, the second spring 2609, and the second piston 2610 move upward as a whole, the hydraulic oil above the second piston 2610 can be pressed into the second oil storage cylinders 2612. The third piston 2613 can move under the action of the oil pressure, thereby driving the first slider 21 to move.

[0036] In this embodiment, as Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown in Figure 9 , symmetrically fixed on both sides of the first rotating cylinder 14 are third oil storage cylinders 2615, and fixed to the outside of the third oil storage cylinders 2615 are second connecting pipes 2614. The first ends of the second connecting pipes 2614 penetrate through the movable ring 2605 and the second slider 2606 and are connected to the first piston 2607. A fourth piston 2616 is slidably connected inside the third oil storage cylinders 2615, and the inner end of the fourth piston 2616 is fixed with a first sleeve 2617. Symmetrically opened on both sides of the first rotating cylinder 14 are first through holes 17. The first sleeve 2617 extends into the first through holes 17. Fixed to the inner wall of the first sleeve 2617 is a third spring 2618, and fixed to the inner end of the third spring 2618 is a plug rod 2619. Symmetrically opened on both sides of the stirring rod 24 are second card slots 25. The plug rods 2619 and the second card slots 25 are arranged in one-to-one correspondence. The second connecting pipes 2614 serve to connect the third oil storage cylinders 2615 and the second oil storage cylinders 2612. When the second slider 2606 moves upward, it drives the first piston 2607, the second spring 2609, and the second piston 2610 to move upward as a whole. After the second piston 2610 moves to the top, when the first piston 2607 continues to move upward, the hydraulic oil between the first piston 2607 and the second piston 2610 can be pressed into the third oil storage cylinders 2615. The fourth piston 2616 moves under the action of the oil pressure, thereby driving the first sleeve 2617 to move. The third spring 2618 plays a role in propping up the plug rod 2619. After the plug rod 2619 penetrates through the second rotating cylinder 20 and is stuck in the second card slot 25, the rotation of the stirring rod 24 will drive the outer cylinder 10 and the inner cylinder 18 to rotate together.

[0037] In this embodiment, as Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, the first card slots 11 are circumferentially and evenly distributed on the outer cylinder 10. The clamping block 2622 is initially stuck in the first card slot 11, and the outer cylinder 10 is in a locked state. When the lifting hook 2603 moves upward, it drives the second sleeve 2620, the fourth spring 2621, and the clamping block 2622 to move upward as a whole. After the clamping block 2622 leaves the first card slot 11, the outer cylinder 10 can be unlocked, enabling the outer cylinder 10 to rotate together with the stirring rod 24. After using the device, when the lifting hook 2603 moves downward, it drives the second sleeve 2620 to move downward. The outer cylinder 10 and the tank body 1 can rotate relative to each other, and finally the clamping block 2622 will be stuck in one of the first card slots 11 to lock the outer cylinder 10 again.

[0038] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 9 shown, on both sides of the second rotating cylinder 20, second through holes 27 are symmetrically formed, and the second through holes 27 are arranged in one-to-one correspondence with the first through holes 17. After the inner cylinder 18 rotates relative to the outer cylinder 10 and aligns the second through holes 27 with the first through holes 17, the fourth piston 2616 moves to drive the first sleeve 2617 and the insertion rod 2619 to move and extend into the second through holes 27. When the second card slot 25 aligns with the second through hole 27, the insertion rod 2619 will automatically spring into the second card slot 25. At the same time, the inner cylinder 18 rotates relative to the outer cylinder 10 and the second opening 19 and the first opening 12 are staggered from each other, and a closed space is formed between the inner cylinder 18 and the outer cylinder 10. When water is passed into the tank body 1, the water is stored between the outer cylinder 10 and the inner wall of the tank body 1.

[0039] The usage method and advantages of the present invention: The volumetric heat exchange unit with the function of cleaning scale works as follows:

[0040] As Figures 1 to 9As shown: the water inlet valve 2 is used to pass the coolant into the tank body 1, and the water outlet valve 3 is used to drain the coolant. The coolant flows from top to bottom in the tank body 1. The liquid inlet pipe 8 is used to pass the medium that needs to be heat exchanged into the first liquid channel 4 and the second liquid channel 7. The liquid outlet pipe 9 is used to drain the medium. The medium flows from bottom to top in the heat exchange pipe 6, which facilitates the heat exchange effect. During the heat exchange process, the stirring rod 24 rotates to automatically stir the coolant. After the heat exchange operation is completed and the coolant is drained, the electric push rod 2601 contracts, and the movable plate 2602 and the lifting hook 2603 The first piston 2607, the second spring 2609 and the second piston 2610 move upward, thereby pulling the movable ring 2605 and the second slider 2606 upward, until the second piston 2610 moves to the top, the third piston 2613 moves under the action of oil pressure, the first slider 21 slides in the first slide groove 16, the second rotating cylinder 20 rotates relative to the first rotating cylinder 14, the second through hole 27 is aligned with the first through hole 17, the inner cylinder 18 rotates relative to the outer cylinder 10, the second opening 19 is completely staggered with the first opening 12, and the inner cylinder 18 and the outer cylinder 10 form a The first piston 2607 is compressed, and the fourth piston 2616 is moved under the action of the oil pressure. The first sleeve 2617, the third spring 2618 and the insertion rod 2619 move as a whole. The insertion rod 2619 passes through the second through hole 27. When the stirring rod 24 rotates and the second slot 25 is aligned with the second through hole 27, the insertion rod 2619 automatically bounces into the second slot 25. At the same time, the lifting hook 2603 moves upward, driving the second sleeve 2620, the fourth spring 2628 and the insertion rod 2619 to move upward. 1 and the block 2622 move upward as a whole, the block 2622 leaves the first slot 11 and unlocks the outer cylinder 10, and water is passed into the tank body 1. The water is stored between the outer cylinder 10 and the inner wall of the tank body 1. The stirring rod 24 rotates to drive the outer cylinder 10 and the inner cylinder 18 to rotate together. The cleaning brush 13 can automatically clean the scale on the heat exchange pipe 6. After cleaning the scale, the lifting hook 2603 is reset, the first sleeve 2617 and the insertion rod 2619 are retracted into the first through hole 17, the first opening 12 and the second opening 19 are re-aligned, and the block 2622 locks the outer cylinder 10 again.
