DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the embodiments.

[0027] See also Figure 1-6The utility model provides a heat exchanger which is convenient for descaling, comprising a shell 1 and a bottom plate 2.

The racks 3 are fixed to the outer side wall of the shell 1. A heat exchange tube body 4 is arranged inside the shell 1. Two symmetrically distributed pipes 5 are fixed to one side of the shell 1. The pipes 5 are connected to the inside of the shell 1. A matching impurity removal component 6 is arranged inside the shell 1. Through the coordinated arrangement of the heat exchange tube body 4 and the shell 1, the device has the advantages of no need to disassemble the device for descaling and cleaning, and the descaling and cleaning are convenient and quick. It effectively solves the problem of needing to disassemble the device for descaling and cleaning, and can ensure that the heat exchange tube body 4 is in a long-term and effective heat exchange efficiency state.

[0028] Further Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it is worth specifically explaining that the impurity removal component 6 includes a mounting ring 61, which is fixed to the inner side wall of the shell 1, and a rod body 62 is slidably connected to one side of the mounting ring 61, and a brush roller 63 is tightly sleeved on the outer surface of the rod body 62, and the outer surface of the brush roller 63 is in contact with the heat exchange tube body 4 and the shell 1; a transmission ring 64, which is rotatably connected to the inner side wall of the shell 1, and a toothed ring 65 is fixed to one side wall of the transmission ring 64, and a mounting sleeve 66 is fixed to the inner side wall of the shell 1, and a transmission shaft 67 is rotatably connected to one side wall of the mounting sleeve 66, and a spur gear 68 is fixed to one end of the transmission shaft 67, and the spur gear 68 is meshed with the toothed ring 65, and one end of the rod body 62 is fixed to one side wall of the toothed ring 65; a bracket 69, which is fixed to The outer side wall of the shell 1 is fixed, and a servo motor 610 is fixed to the inner side wall of the bracket 69. A shaft 611 is coaxially fixed to one end of the output shaft of the servo motor 610. A bevel gear 612 is provided between the shaft 611 and the transmission shaft 67. The two bevel gears 612 are meshed and connected with each other. Through the setting of the impurity removal component 6, the shell 1 and the heat exchange tube body 4 can be automatically scrubbed and descaled, thereby saving the cost of manual descaling and reducing the cost of use. At the same time, the heat of the heat exchange tube body 4 can be evenly distributed, and the speed of heat transfer can be accelerated, thereby reducing energy consumption. At the same time, it can also prevent the rust inside the shell 1 from adhering to the inner wall of the heat exchange tube body 4, affecting the heat conduction efficiency of the heat exchange tube body 4.

[0029] Further Figure 6As shown, it is worth explaining in detail that a guide groove 7 is opened on the side wall of one side of the mounting ring 61, and the rod body 62 is slidably connected to the inside of the guide groove 7. By sliding the rod body 62 in the guide groove 7, it can not only guide the rod body 62, but also greatly improve the stability of the rod body 62 during operation, thereby avoiding the displacement of the rod body 62 during operation.

[0030] This solution has the following working process: when the heat exchange tube body 4 inside the shell 1 needs to be descaled and cleaned, the shaft 611 is driven by the servo motor 610 to rotate synchronously, and the meshing transmission effect between the two bevel gears 612 is used to drive the transmission shaft 67 to rotate synchronously, so that the spur gear 68 rotates synchronously, and the meshing transmission effect between the spur gear 68 and the toothed ring 65 is used to drive the transmission ring 64 to operate synchronously, so that the rod body 62 operates synchronously, and drives the brush roller 63 to rotate synchronously, and the brush roller 63 cleans the inner wall of the shell 1 and the outer surface of the heat exchange tube body 4, thereby completing the cleaning and descaling work of the heat exchange tube body 4, causing the impurities that fall after cleaning to fall to the bottom of the shell 1, and the impurities are discharged by the sewage pipe 8.

[0031] According to the above working process, it can be known that: through the setting of the impurity removal component 6, the shell 1 and the heat exchange tube body 4 can be automatically scrubbed and descaled, thereby saving the cost of manual descaling, thereby reducing the cost of use, and at the same time, the heat of the heat exchange tube body 4 can be evenly distributed, and the speed of heat transfer can be accelerated, thereby reducing energy consumption, and at the same time, it can also prevent the rust and scale inside the shell 1 from adhering to the inner wall of the heat exchange tube body 4, affecting the heat conduction efficiency of the heat exchange tube body 4, and through the coordinated setting of the heat exchange tube body 4 and the shell 1, the device has the advantages of no need to disassemble the device for descaling and cleaning, and the descaling and cleaning are convenient and fast, which effectively solves the problem of needing to disassemble the device for descaling and cleaning, and can ensure that the heat exchange tube body 4 is in a long-term effective heat exchange efficiency state.

[0032] Further Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it is worth explaining in detail that a sewage pipe 8 is fixed to the outer side wall of the shell 1, and the sewage pipe 8 is connected to the inside of the shell 1. Through the setting of the sewage pipe 8, it is convenient to discharge the dirt and impurities inside the shell 1, the sewage discharge efficiency is higher, and it is convenient for users to operate.

[0033] Further Figure 2As shown, it is worth explaining in detail that the drain pipe 8 is arranged obliquely with respect to the shell 1, and the drain pipe 8 is located directly below the heat exchange tube body 4. The oblique distribution of the drain pipe 8 is conducive to the external discharge of impurities cleaned and dropped from the inside of the shell 1, ensuring that the impurities and dirt are discharged more thoroughly.

[0034] Further Figure 6 As shown, it is worth explaining in detail that two symmetrically distributed connecting rings 9 are fastened and sleeved on the outer surface of the rod body 62, and one side of the connecting ring 9 is in contact with the other side of the mounting ring 61. Through the setting of the connecting ring 9, the stability of the rod body 62 during operation can be greatly improved, avoiding the movement and misalignment of the rod body 62 to affect the cleaning work.

[0035] In summary: by the rod body 62 sliding in the guide groove 7, it can not only guide the rod body 62, but also greatly improve the stability of the rod body 62 during operation, avoiding the displacement of the rod body 62 during operation, and the inclined distribution of the sewage pipe 8 is conducive to the discharge of impurities dropped from the inside of the shell 1 to the outside, ensuring that the impurities and dirt are discharged more thoroughly, and the setting of the connecting ring 9 can greatly improve the stability of the rod body 62 during operation, avoiding the displacement of the rod body 62 and affecting the cleaning work.

[0036] Both the heat exchange tube body 4 and the servo motor 610 can be purchased on the market. Both the heat exchange tube body 4 and the servo motor 610 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
