[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is equipped with an angle adjustment module. The servo motor drives the direction plate to rotate through the rotating shaft, thereby changing the flow direction of the hot air inside the air inlet pipe and the air outlet pipe. The angle adjustment module can accurately control the angle of the direction plate to adjust the wind direction, ensure that the hot air flows evenly in the pipe, and improve the drying efficiency. The wind speed sensor can monitor the wind speed in the air inlet pipe and the air outlet pipe in real time, and provide real-time data feedback for the operator. A wind speed lower than the required value will result in poor drying effect, and a wind speed that is too high will waste energy and damage the equipment. By monitoring the wind speed, the operator can adjust the hot air flow rate in time to ensure that the drying process is carried out in the best state. The wind direction sensor can monitor the wind direction in real time to ensure that the hot air flows in a predetermined direction. Deviations in the wind direction will result in uneven drying and poor drying effect. By monitoring the wind direction, the operator can promptly discover and correct the hot air direction to ensure the stability and reliability of the material drying process. Therefore, the problem of how to adjust the drying angle of the cold dryer can be solved, and the wind speed and wind direction can be monitored, thereby improving the drying efficiency, stability and reliability of the cold dryer.
[0016] 2. The present invention is equipped with a fixing groove, a fixing ring, a filter round tube, an anti-skid pad, a fixing collar and a filter square tube. Through the fixing groove, the fixing ring, the anti-skid pad and the fixing collar, an operator can easily disassemble and install the air inlet pipe and the filter round tube, thereby conveniently performing cleaning and maintenance work and ensuring the continuous and efficient operation of the cold dryer. In addition, through the fixing groove, the fixing ring and the fixing collar, a tight connection between the filter round tube and the air inlet pipe can be ensured, the sealing is enhanced and air leakage is prevented. At the same time, the design of the anti-skid pad and the bolt connection can ensure the stability of the filter module and prevent it from loosening or falling off during the operation of the cold dryer. The design of the filter round tube and the filter square tube can be selected and replaced according to different working environments and requirements. In an environment requiring a larger air volume, a larger caliber filter round tube and filter square tube can be selected to reduce resistance. Therefore, the problems of difficult cleaning and maintenance of the cold dryer, insufficient sealing and stability, and inability to adapt to different environments can be solved.
[0017] 3. The present invention is equipped with a filter square tube, a limit groove 1, a limit groove 2, a fixing frame, a stainless steel filter screen, a fixing plate, a gravity sensor, a filter bag, a limit groove 3, a limit block and a fixing cover. The upper opening door connected by a hinge allows the operator to easily open and close the filter square tube, thereby conveniently performing cleaning and maintenance work. When the filter material reaches saturation or needs to be replaced, the operator takes out the fixing cover through the handle 2, and then takes out the old filter bag inside the stainless steel filter screen and replaces it with a new filter material. When the stainless steel filter screen needs to be cleaned and replaced, the fixing frame and the stainless steel filter screen can be cleaned and replaced by taking out the fixing frame through the handle 1. At the same time, the gravity sensor can monitor the filter inside the filter bag in real time. When the gravity of the material changes and the filter material continues to adsorb impurities, it will cause the gravity to increase. When the adsorption of the filter material reaches the set critical value, the gravity sensor will send a signal to remind the operator to replace the filter bag in time to ensure the continuity and stability of the filtering effect. The design of the fixing frame and the fixing plate can ensure the stability and position fixity of the filter bag inside the filter square tube. At the same time, the design of limit grooves 1, 2, 3 and the limit block further enhances the structural stability of the disassembled filter module to prevent loosening or falling off during the operation of the cold dryer. Therefore, it can solve the problem of how to achieve real-time monitoring of the filtration status, facilitate cleaning and maintenance work, and ensure the continuous and efficient operation of the cold dryer.
[0018] 4. The present invention fills the interior of the filter bag with filter materials, and the filter materials are polyester fiber filter element, glass fiber filter element, activated carbon filter element and ultrafine glass fiber filter element in sequence. The multi-layer filter material can more effectively remove impurities in the hot air, the polyester fiber filter element and the glass fiber filter element can capture larger particles and dust, the activated carbon filter element can adsorb harmful gases and odors, and the ultrafine glass fiber filter element can further filter out tiny particles and bacteria, thereby improving the overall filtration efficiency. By filtering out impurities and harmful substances in the hot air, the damage of these substances to the internal components of the cold dryer can be reduced, thereby extending the service life of the cold dryer, and preventing impurities in the hot air from adhering to the surface of the drying material to ensure the quality of the material. At the same time, different materials require different working environments, and therefore require different filtering effects. The design of the multi-layer filter material can be selected and adjusted according to specific needs to adapt to different working environments. Therefore, it can solve the problem of how to improve the hot air filtration efficiency of the cold dryer, extend the service life of the cold dryer, and ensure the quality of material drying.
