Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder reheating technology, specifically a controllable gas reheating device for low-temperature powders. Background Technology
[0002] In many industrial production processes, especially those involving the processing and handling of powder materials, it is often necessary to reheat powders to maintain their flowability or meet specific process requirements. For example, in the food, chemical, and pharmaceutical industries, the storage and transportation of low-temperature powders are common practices. However, when these powders are used for further processing or packaging, it is often necessary to raise their temperature to a suitable range to ensure product quality and production efficiency.
[0003] Traditional powder reheating methods typically include natural reheating, hot air circulation reheating, and resistance wire heating reheating. However, these methods lack the ability to help the hot air rotate during the powder reheating process, causing the powder to easily accumulate. As a result, the heat transfer of the powder pressed at the bottom is not uniform and efficient, which needs to be optimized. To address the above problems, the inventors have proposed a controllable gas reheating device for low-temperature powders to solve the aforementioned issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example: Figure 1-3 As shown, this utility model provides a technical solution: a controllable gas reheating device for low-temperature powder, including a reheating pipe 1, a fan 11 fixedly connected to one end of the reheating pipe 1, a resistance heater 12 fixedly installed inside the reheating pipe 1, a valve 13 fixedly installed inside the reheating pipe 1 near the resistance heater 12, an electromagnet 14 fixedly installed at the top of the reheating pipe 1, the drive end of the electromagnet 14 connected to the valve 13, a feed pipe 15 fixedly installed at the middle of the top of the reheating pipe 1, a fixing block 16 fixedly installed on one side inside the reheating pipe 1, a rotating shaft 17 rotatably installed at one end of the fixing block 16, a guide plate 18 fixedly connected to the outside of the rotating shaft 17, a driven bevel gear 19 fixedly sleeved at one end of the rotating shaft 17, a motor 20 fixedly installed on one side of the top of the reheating pipe 1, a driving bevel gear 21 fixedly connected to the drive end of the motor 20, the driving bevel gear 21 meshing with the driven bevel gear 19, and a temperature sensor 22 fixedly installed at one end of the valve 13.
[0020] A circular hole 23 is provided at one end of the reheat pipe 1. A first air pipe 24 is fixedly installed on the outside of the circular hole 23. A second air pipe 25 is fixedly connected to one end of the first air pipe 24. One end of the second air pipe 25 is fixedly connected to the fan equipment 11. A first filter element 26 is fixedly installed on the inside of the first air pipe 24. A second filter element 27 is fixedly installed on the inside of the second air pipe 25.
[0021] By adopting the above technical solution, and by setting the first air pipe 24 and the second air pipe 25 together, it is convenient for the warmed air to return to the fan equipment 11 for circulation. The air is then filtered twice by the first filter element 26 and the second filter element 27. After filtration, the air is mixed with fresh air and then heated, which reduces energy consumption and is more economical and practical.
[0022] A V-shaped block 28 is fixedly connected to one end of the first filter element 26.
[0023] By adopting the above technical solution, the powder is diverted by setting the V-shaped block 28, which effectively prevents it from rushing to the first filter element 26 and causing blockage, thus hindering air recirculation.
[0024] A support frame 29 is fixedly installed on the side end of the reheat pipe 1, and one end of the support frame 29 is in contact with the outer surface of the second air pipe 25.
[0025] By adopting the above technical solution, the second air pipe 25 is stably supported by the support frame 29 to prevent it from bending and being damaged due to prolonged suspension.
[0026] A controller 30 is fixedly installed in the center of the front side of the return pipe 1.
[0027] By adopting the above technical solution, the controller 30 is set up to facilitate the control and adjustment of the operation of components such as the fan equipment 11, the electromagnet 14, and the motor 20, and also to receive temperature data from the temperature sensor 22.

[0029] By adopting the above technical solution and setting support legs 31 to support the return pipe 1, the horizontal stability of this equipment is improved.
[0030] Working principle: First, the reheating pipe 1 is adapted to the corresponding processing equipment. Then, powder is poured into the feed pipe 15, and the blower 11 is started to compress and extract air. After the air enters the reheating pipe 1, it is heated by the resistance heater 12. The heated airflow is located on the valve 13, and the temperature of the airflow is monitored by the temperature sensor 22. After the temperature is qualified, the solenoid 14 controls the valve 13 to open to allow airflow. The reheating airflow comes into contact with the powder and warms it to the specified temperature. The motor 20 is started to rotate the drive bevel gear 21. The rotation of the active bevel gear 21 drives the driven bevel gear 19 to rotate, and the rotation of the driven bevel gear 19 drives the rotating shaft 17 and the guide plate 18 to rotate, thereby realizing the rotational airflow to enhance gas-solid mixing, improve heat transfer efficiency, prevent powder agglomeration, ensure uniform heating, and further improve powder recovery efficiency. Through the cooperation of the first air pipe 24 and the second air pipe 25, the recovered air can easily return to the fan equipment 11 for circulation. The air is then filtered twice by the first filter element 26 and the second filter element 27. After filtration, it is mixed with fresh air and then heated, reducing energy consumption and making it more economical and practical.
