[0030] like Figures 1-3 As shown, the device includes a heat exchange tube 1, with a control tube 2 fixedly connected to the end of the heat exchange tube 1; a baffle plate 8 fixedly connected inside the heat exchange tube 1; a U-shaped cold liquid tube 9 slidably connected inside the baffle plate 8, and three U-shaped cold liquid tubes 9 are arranged in a circumferential array; a sealing block 10 fixedly connected to the end of the U-shaped cold liquid tube 9; a screw 12 threadedly connected between the baffle plate 8 and the control tube 2; a connecting rod 23 rotatably connected to the end of the screw 12; a second fixing block 14 fixedly connected to the end of the connecting rod 23; a through hole opened on the surface of the second fixing block 14, and the through hole is set according to the size and position of multiple U-shaped cold liquid tubes 9; a sealing plate 11 fixedly connected between the control tube 2 and the baffle plate 8, and two sealing plates 11 are arranged symmetrically; a handle 21 fixedly connected to the end of the screw 12 away from the connecting rod 23; an inlet 5 and an outlet 6 fixedly connected to the side wall of the heat exchange tube 1; and a cold liquid injection port 3 and a cold liquid return port 4 fixedly connected to the side wall of the control tube 2.
[0031] The working principle of the above technical solution is as follows:
[0032] The worker can pour two kinds of liquid or gas into the passageway from the cold liquid injection port 3 to the cold liquid return port 4 and the passageway from the cold liquid injection port 3 to the cold liquid return port 4, so that they are indirectly contacted with the plurality of U-shaped cold liquid pipes 9 inside the heat exchange pipe 1 and the control pipe 2 to exchange heat, wherein the two sealing plates 11 play a role in blocking the cold liquid injection port 3 and the cold liquid return port 4, and when the heat exchanger needs to be cleaned, the worker can rotate the handle 21 at the end of the control pipe 2, so that the screw rod 12 rotates relative to the heat exchange pipe 1 and the control pipe 2, and the first fixed block 13 connected with the screw rod 12 moves horizontally, and the second fixed block 14 and the plurality of U-shaped cold liquid pipes 9 move synchronously, until the sealing block 10 at the end of the plurality of U-shaped cold liquid pipes 9 contacts the inner side wall of the control pipe 2, at this time, the worker can introduce the cleaning liquid into the control pipe 2 through the cold liquid injection port 3, and then the cleaning liquid enters the heat exchange pipe 1 through the gap between the U-shaped cold liquid pipe 9 and the sealing block 10, and finally is discharged from the cold liquid return port 4, wherein the second fixed block 14 with a through hole plays a role in fixing the end of the plurality of U-shaped cold liquid pipes 9, this step exchanges heat through the plurality of U-shaped cold liquid pipes 9 arranged in a circumferential array, controls the liquid passageway of the plurality of U-shaped cold liquid pipes 9 through the screw rod 12, the first fixed block 13 and the second fixed block 14, and finally realizes the self-cleaning function of the heat exchanger, expands the function of the heat exchanger, improves the flexibility, is helpful to reduce the maintenance cost and shorten the maintenance time.
[0033] In another embodiment, as shown in Figure 4 The end of the screw rod 12 is fixedly connected with the third fixed block 16, and the end of the third fixed block 16 corresponds to the size of the first fixed block 13, the third fixed block 16 and the first fixed block 13 are provided with a sliding groove inside, and the two sliding grooves are correspondingly provided, the sliding groove is provided with a rotating ball 17 inside, and the plurality of rotating balls 17 are arranged in a circumferential array, and the plurality of rotating balls 17 are provided with a filling block 18, and the two ends of the filling block 18 correspond to the size of the rotating ball 17.
[0034] The rotation connection of the screw rod 12 and the first fixed block 13 is realized by the third fixed block 16, the rotating ball 17 and the filling block 18. When the third fixed block 16 at the end of the screw rod 12 rotates, the rotating balls 17 between the third fixed block 16 and the first fixed block 13 move in the sliding groove between the first fixed block 13 and the third fixed block 16. The first fixed block 13 and the third fixed block 16 can realize good stress transmission through the rotating balls 17 and the filling blocks 18. At the same time, the filling blocks 18 can limit the position of the rotating balls 17, so as to avoid the first fixed block 13 and the third fixed block 16 from falling off. This step realizes the rotation connection of the screw rod 12 and the first fixed block 13 through the rotating balls 17 and the filling blocks 18, and meets the stress transmission requirement between the screw rod 12 and the first fixed block 13, which is beneficial to avoid the separation of the screw rod 12 and the first fixed block 13, enhances the stability and durability of the heat exchanger, and is beneficial to prolong the service life of the heat exchanger.

[0036] When the U-shaped cold liquid pipe 9 moves in the heat exchange pipe 1, the lunettes 15 fixedly connected to the side wall of the U-shaped cold liquid pipe 9 can effectively contact the inside of the heat exchange pipe 1, so as to limit the screw rod 12 and the first fixed block 13, and prevent the screw rod 12 from tilting. During daily use, the lunettes 15 can block the medium and prolong the time of the medium staying in the heat exchange pipe 1, so as to realize good heat exchange effect. This step supports the lunettes 15 on the side wall of the U-shaped cold liquid pipe 9, so that the movement of the U-shaped cold liquid pipe 9 is more smooth, the stability of the heat exchanger is improved, and the heat exchange effect of the heat exchanger is improved.
[0037] In another embodiment, as shown in Figure 3 The inside of the control pipe 2 is fixedly connected with a boss 19, and the bosses 19 correspond to the position of the sealing block 10. The side wall of the boss 19 is fixedly connected with a plug 20, and the plug 20 corresponds to the size of the sealing block 10.
[0038] Whenever multiple U-shaped cold liquid pipes 9 move towards the inner wall of the control pipe 2 along with the rotation of the screw 12, the sealing block 10 at the end of the U-shaped cold liquid pipe 9 will first come into contact with the blocking block 20 on the side wall of the boss 19. The blocking block 20 corresponding to the size of the sealing block 10 can effectively block the passage of the U-shaped cold liquid pipe 9 by itself. This step improves the self-cleaning function of the heat exchanger by setting the boss 19 and the blocking block 20, which is conducive to avoiding the medium entering the inside of the U-shaped cold liquid pipe 9 through the gap between the U-shaped cold liquid pipe 9 and the control pipe 2, thereby avoiding the cleaning agent staying inside the U-shaped cold liquid pipe 9.
[0039] In another embodiment, as shown in Figure 3 the end of the sealing block 10 is fixedly connected with a sealing ring 22, and multiple sealing rings 22 are arranged corresponding to the size of the blocking disc 8.
[0040] When multiple sealing blocks 10 stay inside the blocking disc 8, the staff can compress the sealing ring 22 between the sealing block 10 and the blocking disc 8 by rotating the screw 12, so that the sealing ring 22 is deformed to fill the gap. This step fills the gap between the sealing block 10 and the blocking disc 8 by setting the sealing ring 22, avoiding the hard contact between the sealing block 10 and the blocking disc 8, thereby eliminating the mutual pollution of the two media and eliminating the safety hazard, and improving the stability of the heat exchanger.
[0041] In another embodiment, as shown in Figure 1 the side wall of the cold liquid injection inlet 3 and the cold liquid return port 4 is fixedly connected with a fixed ring 7, and the side wall of the inlet 5 and the outlet 6 is fixedly connected with a fixed ring 7.
[0042] This step increases the contact area of the cold liquid injection inlet 3, the cold liquid return port 4 and the control pipe 2 by setting the fixed ring 7, and increases the contact area of the inlet 5, the outlet 6 and the heat exchange pipe 1, which is conducive to avoiding the cold liquid injection inlet 3, the cold liquid return port 4, the inlet 5 and the outlet 6 from falling off, and improves the durability of the heat exchanger.
[0043] In another embodiment, as shown in Figure 1 the screw 12, the first fixed block 13, the third fixed block 16, the rotating ball 17, the filling block 18 and the connecting rod 23 are made of aluminum alloy.
[0044] The screw rod 12, the first fixed block 13, the third fixed block 16, the rotating ball 17 and the filling block 18 made of aluminum alloy material can effectively avoid rust and eliminate medium pollution, the plurality of components are made of aluminum alloy material to eliminate medium pollution, and the service life is prolonged and the stability of the heat exchanger is improved.
