Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1 、Figure 2 、 Figure 3 and Figure 5 It can be seen that the utility model provides a technical solution: a heat exchanger that is easy to add a descaling agent, comprising: a heat exchanger body 1, a hot air inlet 2, a cold air outlet 3, a baffle 4, a tube bundle 5, a head 6, a cold water inlet 7, a hot water outlet 8 and a support base 9. The top of the heat exchanger body 1 is connected to the hot air inlet 2, and the bottom of the heat exchanger body 1 is connected to the cold air outlet 3. The baffle 4 is installed inside the heat exchanger body 1, and the tube bundle 5 is connected through the inside of the baffle 4. One end of the heat exchanger body 1 is connected to the head 6, the top of the head 6 is connected to the cold water inlet 7, the bottom of the head 6 is connected to the hot water outlet 8, the bottom of the heat exchanger body 1 is connected to the support base 9, and a storage box 10 is installed on the top of the head 6. A through hole 11 is provided between the storage box 10 and the head 6. The top of the material box 10 is threadedly connected to a sealing cover 12, and the interior of the material storage box 10 is connected to a support block 13, and an inclined plate 14 is commonly connected between the top of the support block 13 and the inner wall of the material storage box 10. A limiting groove 15 is provided on the inner wall of the material storage box 10, and a magnetic block 16 is installed on the side of the limiting groove 15 close to the support block 13. The interior of the support block 13 is slidably connected to a sealing plate 17, and the sealing plate 17 is connected to the outside of the magnetic block 16 close to the sealing plate 17, and the bottom of the rack 18 is connected to an iron block 19. The interior of the material storage box 10 close to the rack 18 is connected to a rotating shaft 20 through a bearing, and a gear 21 is welded to the outside of the rotating shaft 20. A meshing structure is formed between the gear 21 and the rack 18, and a magnetic attraction structure is formed between the iron block 19 and the magnetic block 16. The shape of the sealing plate 17 is T-shaped.

[0026] In specific implementation, the heat exchanger is a heat exchange device. The heat exchanger can improve the utilization rate of energy. During the use of the heat exchanger, scale is easily formed inside the tube bundle 5. The scale will affect the heat exchange effect of the heat exchanger body 1. It is troublesome for personnel to add descaling agent. You can first unscrew the sealing cover 12 and add the descaling agent into the storage box 10. The descaling agent will accumulate on the top of the inclined plate 14 and the sealing plate 17. After the descaling agent is added, cover the sealing cover 12. After the tube bundle 5 has been used for a certain period of time, the shaft 20 can be reversed. When the shaft 20 rotates, it can drive the gear 21 to rotate. When the gear 21 rotates, it can mesh and drive The rack 18 rotates, and when the rack 18 moves, it can drive the sealing plate 17 and the iron block 19 to move. When the iron block 19 moves, it can separate from the magnetic block 16. When the sealing plate 17 moves, it can slide with the support block 13, and when the sealing plate 17 moves, the end away from the rack 18 will gradually separate from the inner wall of the storage box 10. At this time, the descaling agent on the inclined plate 14 and the sealing plate 17 can enter the interior of the head 6 through the through hole 11. When the water inside the cold water inlet 7 enters the interior of the head 6, the water can be mixed with the descaling agent and flow into the tube bundle 5. The descaling agent can dissolve the scale inside the tube bundle 5, thereby achieving the purpose of descaling.

[0027] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the descaling agent can be simply and conveniently added to the tube bundle 5 through the storage tank 10, so that the scale in the tube bundle 5 is removed, without disassembling the pipeline connected to the cold water inlet 7.

[0029] In specific implementation, the heat exchanger can be used for heating, cooling, evaporation, condensation and other processes, to meet different production needs. During use, the bottom cold gas outlet 3 and the bottom end of the hot water outlet 8 of the heat exchanger main body 1 are connected to corresponding pipelines. Since the support height of the support seat 9 is limited, the height of some connected pipelines can be higher than the support seat 9, which makes it difficult to place the heat exchanger main body 1, and objects need to be placed at the bottom of the support seat 9 to place the heat exchanger main body 1. This process is relatively troublesome. When the heat exchanger main body 1 is hoisted to the designated position by hoisting equipment, the threaded column 28 can be loosened, so that the end of the threaded column 28 can be threadedly slid out of the second threaded hole 26. At this time, the threaded column 28 no longer fixes the extension block 24, so that the extension block 24 can slide downward under the action of its own gravity. When the extension block 24 slides to the maximum position, the inner top end thereof falls on the limit seat 23, so that the extension block 24 cannot continue to slide, and thus the end of the threaded column 28 can be rotated into the first threaded hole 25. The support seat 9 and the extension block 24 can be threadedly fixed together by the threaded column 28.

[0030] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 , when the two groups of extension blocks 24 are fixed, the extension blocks 24 can extend the support height of the support seat 9. At this time, the support plate 27 can be placed on the ground, the pipelines connected to the bottom ends of the cold gas outlet 3 and the hot water outlet 8 can be smoothly installed, and the heat exchanger main body 1 can be stably placed on the ground without using objects to pad.

[0031] In summary, when the heat exchanger is used, the sealing cover 12 can be screwed off, the descaling agent is added into the storage tank 10, the descaling agent is accumulated on the top of the inclined plate 14 and the sealing plate 17, the sealing cover 12 is covered after the addition of the descaling agent is completed, the descaling agent can dissolve the scale in the pipe bundle 5, so that the purpose of descaling is achieved, the descaling agent can be simply and conveniently added into the pipe bundle 5 through the storage tank 10, so that the scale in the pipe bundle 5 is removed, and the pipeline connected with the cold water inlet 7 does not need to be disassembled, when the two groups of extension blocks 24 are fixed, the extension blocks 24 can extend the support height of the support seat 9, at this time, the support plate 27 can be placed on the ground, the pipeline connected with the bottom end of the cold gas outlet 3 and the hot water outlet 8 can be smoothly installed, and the heat exchanger body 1 can be stably placed on the ground, and an object pad is not needed.
