[0002] As a continuous drying equipment, belt dryers are widely used in many industries such as food, medicine, chemical, and agricultural and sideline product processing due to their high-efficiency drying capacity and continuous operation advantages. In the food industry, they are often used for dehydration and drying of fruit slices, dried vegetables, and meat products. In the pharmaceutical industry, they can be used to dry Chinese medicinal materials and pharmaceutical granules. In the chemical field, they are suitable for drying and processing various chemical raw materials. During the operation of a belt dryer, the control of heating temperature is crucial to the drying quality of the materials.

[0003] Existing belt dryers have some shortcomings in heating temperature control. The heating temperature control of some belt dryers is not precise enough, which can easily lead to large temperature fluctuations, affecting the drying effect of materials. In addition, the distribution of hot air in the dryer is not uniform, which can easily lead to uneven drying of materials and reduce product quality. Corresponding solutions are needed.

[0006] According to the above-mentioned belt dryer with built-in heating temperature control structure, the power assembly includes a first rotating shaft disposed inside the shell, the first rotating shaft being rotatably connected to the two side walls of the shell through bearings, and multiple power plates being fixedly connected to the first rotating shaft in the circumferential direction.

[0007] According to the above-mentioned belt dryer with built-in heating temperature control structure, the uniform air outlet assembly includes a second rotating shaft disposed inside the shell. The second rotating shaft is rotatably connected to the two side walls of the shell through bearings. Two sleeves are rotatably connected to the inner wall of the shell.

Nuts are threadedly connected to each of the two reciprocating threaded rods. The bottom surfaces of the two guide plates are respectively hinged to the upper surfaces of the two nuts.

[0008] According to the above-mentioned belt dryer with built-in heating temperature control structure, the transmission component includes a drive wheel and a driven wheel that are circumferentially fixedly connected to a first rotating shaft and a second rotating shaft, and a belt is sleeved between the drive wheel and the driven wheel.

[0009] According to the belt dryer with a built-in heating temperature control structure described above, multiple power plates are located inside the housing and below the output end of the air inlet pipe.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: Refer to Figures 1 to 3 A belt dryer with a built-in heating temperature control structure includes a belt dryer body 1; The temperature control mechanism includes a temperature control component 2, a power component 3, a uniform air outlet component 4, and a transmission component 5. The temperature control component 2 includes an air inlet pipe 21 fixedly connected to the top surface of the belt dryer body 1. The output end of the air inlet pipe 21 is fixedly connected to a housing 22. A temperature sensor 23 is fixedly installed on the side wall of the housing 22. Two electric heaters 24 are fixedly installed on the inner wall of the air inlet pipe 21. A PLC controller 25 is fixedly installed on the side wall of the belt dryer body 1. The electric heaters 24 and the temperature sensor 23 are electrically connected to the PLC controller 25. The power assembly 3 includes a first rotating shaft 31 located inside the housing 22. The first rotating shaft 31 is rotatably connected to the two side walls of the housing 22 through bearings. Multiple power plates 32 are fixedly connected to the first rotating shaft 31 in the circumference. The multiple power plates 32 are all located inside the housing 22 and are all located below the output end of the air inlet pipe 21. The uniform air outlet assembly 4 includes a second rotating shaft 41 located inside the housing 22. The second rotating shaft 41 is rotatably connected to the two side walls of the housing 22 through bearings. Two sleeves 42 are rotatably connected to the inner wall of the housing 22. A guide plate 43 is slidably connected inside each of the two sleeves 42. Two reciprocating threaded rods 44 are circumferentially fixedly connected to the second rotating shaft 41. Nuts 45 are threadedly connected to each of the two reciprocating threaded rods 44. The bottom surfaces of the two guide plates 43 are respectively hinged to the upper surfaces of the two nuts 45. The transmission assembly 5 includes a driving wheel 51 and a driven wheel 52 circumferentially fixedly connected to the first rotating shaft 31 and the second rotating shaft 41. A belt 53 is sleeved between the driving wheel 51 and the driven wheel 52. The driving wheel 51 and the driven wheel 52 are both located outside the housing 22. The diameter of the driving wheel 51 is larger than the diameter of the driven wheel 52.

[0020] The working principle of this utility model is as follows: When in use, airflow is input into the drying chamber of the belt dryer body 1 through the air inlet pipe 21, and the electric heater 24 is started to heat the airflow to achieve the purpose of hot air drying. During the hot air drying process, the air inlet pipe 21 of the temperature control component 2 introduces external air into the housing 22, the electric heater 24 heats the air, the temperature sensor 23 monitors the temperature inside the belt dryer body 1 in real time and transmits the data to the PLC controller 25. When the temperature is lower than the set value, the PLC controller 25 controls the electric heater 24 to increase the heating power, and when the temperature is higher than the set value, the PLC controller 25 controls the electric heater 24 to reduce the heating power or stop working, thereby accurately controlling the heating temperature. When the power assembly 3 is working, the airflow input through the air inlet pipe 21 drives the power plate 32 to rotate. The power plate 32 drives the first rotating shaft 31 to rotate, using the power of the airflow to provide power for the uniform air outlet assembly 4. Under the action of the transmission assembly 5, the first rotating shaft 31 drives the second rotating shaft 41 to rotate through the driving wheel 51, belt 53 and driven wheel 52. The second rotating shaft 41 drives the reciprocating threaded rod 44 to rotate. Since the nut 45 is threadedly connected to the reciprocating threaded rod 44, the rotation of the reciprocating threaded rod 44 causes the nut 45 to reciprocate. The nut 45 drives the guide plate 43 to slide and swing back and forth inside the housing 42. The swing of the guide plate 43 can change the flow direction of the hot air, so that the hot air is blown out evenly from the housing 22 and distributed in the belt dryer body 1, ensuring that all parts of the material are heated evenly, and effectively avoiding the phenomenon of local overheating or uneven temperature distribution, thereby achieving a more precise temperature control.
