[0002] In the production process of polysilicon, heat exchangers are often used to cool or heat chlorosilane, among which tube-sheet heat exchangers with tubes are generally used. However, since the cooling water used in the heat exchanger is often exposed to the environment and may contain silt or microbial growth, or if the heat exchanger is damaged and chlorosilane leaks into the water, the cooling water reacts with the chlorosilane to generate solid silicon dioxide, which adheres to the tubes and causes the tubes to be blocked. Therefore, there is an urgent need for a cleaning tool for clearing the blockage of the heat exchanger tubes, which can realize the cleaning of the heat exchanger after the tubes are blocked, and avoid the blockage or scrapping of the heat exchanger tubes.

[0026] The height of the cleaning pipe 49 is changed by the lifting mechanism 3. When the height is appropriate, the adjustment mechanism 2 and the cleaning mechanism 4 cooperate to clean the array of pipes to prevent the array of pipes from being blocked.

[0027] like Figure 2 As shown, the output end of the motor 21 is fixedly connected to a threaded rod 22, the left end of the threaded rod 22 is rotatably connected to the middle part of the right end of the connecting plate 11, the right part of the outer wall of the threaded rod 22 is threadedly connected to a connecting block 23, the bottom end of the connecting block 23 is slidably connected to the top end of the base plate 1, the front and rear parts of the connecting block 23 are both slidably connected to a guide rod 24, and the bottom end of the guide rod 24 is fixedly connected to the top end of the base plate 1.

[0028] By starting the motor 21, the threaded rod 22 is driven to rotate, so that the connecting block 23 moves on the outer surface of the threaded rod 22, and at the same time, the inner wall of the connecting block 23 slides on the outer wall of the guide rod 24, thereby driving the cleaning tube 49 to the inner wall of the array tube.

[0029] like Figure 2 , Figure 3 As shown, the front and rear parts of the bottom of the connecting block 23 are fixedly connected with the guide block 25, the outer wall of the guide block 25 is slidably connected with the inner wall of the bottom plate 1, and the outer shape of the guide block 25 is T-shaped.

[0030] When the connecting block 23 moves, it drives the guiding block 25 to slide synchronously on the inner wall of the bottom plate 1 , and the guiding block 25 limits the connecting block 23 so that the connecting block 23 can only move horizontally.

[0031] like Figure 2 , Figure 4 As shown, a motor 2 32 is fixedly connected to the bottom of the inner cavity of the rear fixed box 31, a threaded rod 2 33 is fixedly connected to the output end of the motor 2 32, the top of the threaded rod 2 33 is rotatably connected to the top of the inner cavity of the rear fixed box 31, a transmission belt 34 is transmission-connected to the bottom of the output end of the motor 2 32, the front of the transmission belt 34 is transmitted by a threaded rod 35, and the top of the threaded rod 35 is rotatably connected to the top of the inner cavity of the front fixed box 31.

[0032] By starting the second motor 32 , the second threaded rod 33 is driven to rotate, and the transmission belt 34 is driven to rotate synchronously. The transmission belt 34 drives the third threaded rod 35 to rotate synchronously, thereby causing the slider 36 to slide on the outer walls of the second threaded rod 33 and the third threaded rod 35 .

[0033] like Figure 2 , Figure 4 As shown, the bottom of the threaded rod 2 33 and the threaded rod 35 are both threadedly connected with a slider 36, the outer wall of the slider 36 is slidably connected to the bottom of the inner cavity of the fixed box 31, one end of the slider 36 is fixedly connected to a support plate 37, one end of the support plate 37 is slidably connected to the outer wall of the fixed box 31, and the top of the support plate 37 is fixedly connected to a fixing rod 38.

When the height of the cleaning tube 49 is appropriate, the motor 2 32 can be turned off to adjust the height.

[0035] like Figure 2 , Figure 5 As shown, the front part of the top of the water tank 41 is fixedly connected to the water inlet 42, the top of the left end of the water tank 41 is fixedly connected to the fixing plate 421, the middle part of the top of the water tank 41 is fixedly connected to the water pump 43, the input end of the water pump 43 is fixedly connected to the water inlet pipe 45, the output end of the water pump 43 is fixedly connected to the hose 46, the top of the fixing plate 421 is movably connected to the outer wall of the hose 46, the top of the inner cavity of the water tank 41 is fixedly connected to the filter screen 44, and the middle part of the filter screen 44 is fixedly connected to the top of the water inlet pipe 45.

[0036] Water is added to the water tank 41 through the water inlet 42. When the water enters the water tank 41, it is filtered through the filter 44 to filter out impurities in the water, thereby avoiding excessive impurities in the water and preventing the subsequent cleaning pipe 49 from being blocked, thereby preventing the cleaning pipe 49 from being blocked. After that, the water pump 43 is started, and the water in the water tank 41 is pumped out through the water inlet pipe 45 and transported to the hose 46.

[0038] When water enters the hose 46, the hose 46 transports the water to the conical head 47, and the conical head 47 transports the water to the cleaning tube 49. The water is discharged from the through hole on the cleaning tube 49 to clean the inner wall of the tube array, achieving a cleaning effect.

[0039] The working principle of the utility model is as follows: when in use, water is added to the water tank 41 through the water inlet 42. When the water enters the water tank 41, it is filtered through the filter screen 44 to filter out impurities in the water, avoiding excessive impurities in the water and preventing the subsequent cleaning pipe 49 from being blocked, thereby preventing the cleaning pipe 49 from being blocked. After that, the device is adjusted by starting the motor 2 32 to drive the threaded rod 2 33 to rotate, and at the same time drive the transmission belt 34 to rotate synchronously, and the transmission belt 34 drives the threaded rod 35 to rotate synchronously, thereby making the slider 36 slide on the outer wall of the threaded rod 2 33 and the threaded rod 35, driving the support plate 37 to move synchronously, the support plate 37 drives the fixing rod 38 and the fixing block 48 to move synchronously, and the fixing block 48 drives the cleaning pipe 49 to move synchronously. When the height of the cleaning pipe 49 is appropriate, the motor 2 32 can be turned off, thereby achieving the effect of adjusting the height, and then the conical head of the cleaning pipe 49 can be aligned with the inlet of the array of tubes. , then start the motor 21 to drive the threaded rod 22 to rotate, so that the connecting block 23 moves on the outer surface of the threaded rod 22, and at the same time, the inner wall of the connecting block 23 slides on the outer wall of the guide rod 24, and the connecting block 23 drives the guide block 25 to slide on the inner wall of the bottom plate 1 synchronously, and the guide block 25 limits the connecting block 23 so that the connecting block 23 can only move horizontally, thereby driving the cleaning tube 49 to poke toward the inner wall of the array tube. During the poking process, the dirt on the inner wall of the array tube is loosened and falls off, thereby repeatedly making the cleaning tube 49 enter and exit the inner wall of the array tube. At the same time, start the water pump 43, and the water inlet pipe 45 draws water from the water tank 41 and transports it to the hose 46, and the hose 46 transports the water to the conical head 47, and the conical head 47 transports the water into the cleaning tube 49, and the water is discharged from the through hole on the cleaning tube 49, so as to clean the inner wall of the array tube, thereby achieving a cleaning effect, thereby greatly improving the user experience.
