[0023] In this embodiment, as Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 9 shown, four first openings 12 are opened on the side surface of the outer cylinder 10, a first rotating cylinder 14 is fixed at the top of the outer cylinder 10, the first rotating cylinder 14 extends into the groove 15, four second openings 19 are opened on the side surface of the inner cylinder 18, a second rotating cylinder 20 is fixed at the top of the inner cylinder 18, first sliders 21 are symmetrically fixed on both sides of the second rotating cylinder 20, the first sliders 21 are slidably connected to the inner wall of the first rotating cylinder 14, first sliding grooves 16 are symmetrically opened on both inner walls of the first rotating cylinder 14, and a first spring 22 is fixed on one inner wall of the first sliding groove 16. The first slider 21 is fixed at one end of the first spring 22, and the first slider 21 is slidably connected in the first sliding groove 16. The first spring 22 plays a role in propping up 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.

[0024] In this embodiment, as Figure 2As shown in the figure, a motor 23 is fixedly installed inside the bottom of the tank body 1, and the top of the motor 23 is connected to a 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.

[0025] In this embodiment, as Figure 2 , Figure 7 , Figure 8 and Figure 9 shown, the linkage rotating mechanism 26 penetrates through the inner wall of the first rotating cylinder 14 and is connected to the first slider 21. The linkage rotating mechanism 26 is snap-connected to the top of the outer cylinder 10. Second sliding grooves 2604 are symmetrically formed on both sides of the first rotating cylinder 14. A movable ring 2605 is sleeved outside the first rotating cylinder 14, and 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, and a first piston 2607 is fixed to the top of the second slider 2606. 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 a second piston 2610 through a second spring 2609, and both the first piston 2607 and the second piston 2610 are slidably connected in the first oil storage cylinders 2608. When the lifting hook 2603 moves upward, it can lift the movable ring 2605 and the two second sliders 2606 upward, and the first piston 2607, the second spring 2609, and the second piston 2610 move upward as a whole, facilitating the extrusion of the hydraulic oil above the second piston 2610. When the first piston 2607 moves 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 extrusion of the hydraulic oil between the first piston 2607 and the second piston 2610.

[0026] In this embodiment, as Figure 6 and Figure 8 shown, second oil storage cylinders 2612 are symmetrically fixed inside the two side walls of the first rotating cylinder 14, and the second oil storage cylinders 2612 are connected to the side surface of the top of the first oil storage cylinders 2608 through a first connecting pipe 2611. A third piston 2613 is slidably connected in the second oil storage cylinders 2612, and the third piston 2613 is fixed to one side of the first slider 21. The first connecting pipe 2611 serves to connect the first oil storage cylinders 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, and the third piston 2613 can move under the action of the oil pressure, thereby driving the first slider 21 to move.

[0027] In this embodiment, as Figure 2 , Figure 7, Figure 8 and Figure 9 As shown, on both sides of the first rotary drum 14, third oil storage cylinders 2615 are symmetrically fixed. On the outside of the third oil storage cylinders 2615, second connecting pipes 2614 are fixed. The head end of the second connecting pipe 2614 penetrates through the movable ring 2605 and the second slider 2606 and is connected to the first piston 2607. A fourth piston 2616 is slidably connected in the third oil storage cylinder 2615. The inner end of the fourth piston 2616 is fixed with a first sleeve 2617. On both sides of the first rotary drum 14, first through holes 17 are symmetrically opened. The first sleeve 2617 extends into the first through hole 17. A third spring 2618 is fixed on the inner wall of the first sleeve 2617. The inner end of the third spring 2618 is fixed with a plug rod 2619. Second clamping grooves 25 are symmetrically opened on both sides of the stirring rod 24. The plug rods 2619 and the second clamping grooves 25 are arranged in one-to-one correspondence. The second connecting pipe 2614 serves to connect the third oil storage cylinder 2615 and the second oil storage cylinder 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 upward 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 cylinder 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 acts as a support for the plug rod 2619. After the plug rod 2619 penetrates through the second rotary drum 20 and is stuck in the second clamping groove 25, the rotation of the stirring rod 24 will drive the outer cylinder 10 and the inner cylinder 18 to rotate together.

[0028] In this embodiment, as Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 and Figure 9 shown, the first clamping grooves 11 are circumferentially and evenly distributed on the outer cylinder 10. The clamping blocks 2622 are initially stuck in the first clamping grooves 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 blocks 2622 to move upward as a whole. After the clamping blocks 2622 leave the first clamping grooves 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 the clamping blocks 2622 will eventually be stuck in one of the first clamping grooves 11 to lock the outer cylinder 10 again.

[0029] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 9As shown, second through holes 27 are symmetrically formed on both sides of the second rotating cylinder 20, 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 slots 25 are aligned with the second through holes 27, the insertion rod 2619 will automatically spring into the second card slots 25. At the same time, the inner cylinder 18 rotates relative to the outer cylinder 10 and the second openings 19 are staggered from the first openings 12, 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.

[0030] The usage method and advantages of the present invention: The volume type heat exchange unit with the function of cleaning water scale works as follows: As Figures 1 to 9As shown in the figure: The inlet valve 2 is used to supply coolant into the tank body 1, and the outlet valve 3 is used to drain the coolant. The coolant flows downward in the tank body 1. The liquid inlet pipe 8 is used to supply the medium to be heat-exchanged into the first liquid passage 4 and the second liquid pipe 7, and the liquid outlet pipe 9 is used to drain the medium. The medium flows upward in the heat exchange pipe 6, which is convenient to achieve the heat exchange effect. During the heat exchange process, the stirring rod 24 rotates to automatically stir the coolant. After completing the heat exchange operation and draining the coolant, the electric push rod 2601 contracts, and the movable plate 2602 and the lifting hook 2603 move upward, thereby lifting the movable ring 2605 and the second slider 2606 upward. The first piston 2607, the second spring 2609 and the second piston 2610 move upward as a whole 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 chute 16, the second rotating cylinder 20 rotates relative to the first rotating cylinder 14, the second through hole 27 aligns with the first through hole 17, the inner cylinder 18 rotates relative to the outer cylinder 10, and the second opening 19 is completely staggered from the first opening 12. The inner cylinder 18 and the outer cylinder 10 form a closed space. Then the lifting hook 2603 continues to move upward, the first piston 2607 continues to move upward, the second spring 2609 is compressed, and the fourth piston 2616 moves under the action of oil pressure. The first sleeve 2617, the third spring 2618 and the inserting rod 2619 move as a whole. The inserting rod 2619 passes through the second through hole 27. When the stirring rod 24 rotates and aligns the second clamping groove 25 with the second through hole 27, the inserting rod 2619 automatically springs into the second clamping groove 25. At the same time, the upward movement of the lifting hook 2603 drives the second sleeve 2620, the fourth spring 2621 and the clamping block 2622 to move upward as a whole. The clamping block 2622 leaves the first clamping groove 11 and unlocks the outer cylinder 10. Water is supplied into the tank body 1, and the water is stored between the outer cylinder 10 and the inner wall of the tank body 1. The rotation of the stirring rod 24 drives the outer cylinder 10 and the inner cylinder 18 to rotate together, and the cleaning brush 13 can automatically clean the scale on the heat exchange pipe 6. After cleaning the scale, the lifting hook 2603 resets, the first sleeve 2617 and the inserting rod 2619 retract into the first through hole 17 again, the first opening 12 aligns with the second opening 19 again, and the clamping block 2622 locks the outer cylinder 10 again.

[0031] In summary, the volumetric heat exchanger unit with the function of cleaning scale achieves the purposes of uniform heat exchange, automatic scale cleaning and water saving, and meets the usage requirements of people.
