[0002] With the continuous development of plastic industry, the wide application of plastic materials puts forward higher requirements for its drying treatment. Plastic particles often need to be dried in the production process to remove the moisture on the surface or inside, so as to avoid the influence of excessive moisture on the subsequent processing technology. The existence of moisture not only affects the processing performance of plastics, but also may cause defects in finished products, such as bubbles, uneven surface or unstable quality, etc. Therefore, as a kind of key equipment, plastic drying machine has been widely used in plastic production process to ensure the quality stability of plastic particles.
[0003] Many existing equipment has low heat conduction efficiency of hot air in the drying process, resulting in serious waste of heat, long drying time, and increased energy consumption and production cost.
[0004] Due to uneven distribution of hot air, part of the plastic particles may not be fully dried, resulting in unstable drying effect. It is difficult to control the temperature in the drying process. If the temperature is too high, it may cause damage to the plastic particles; if the temperature is too low, it will lead to incomplete drying and affect the subsequent processing.
[0005] The traditional drying machine often loses hot air during use, cannot effectively recover heat energy, and has low energy utilization rate.

Detailed Implementation
[0021] like Figs. 1 to 5 As shown, a plastic dryer includes a mounting bracket 10, a hopper 20 mounted in the middle of the mounting bracket 10, a heating system installed inside the hopper 20, a material cover 21 mounted on the top of the hopper 20, and a heating air inlet 211 at one end of the material cover 21. A fan is connected to the heating air inlet 211. In use, the fan draws in air from the outside, and the air enters the hopper 20 through the heating air inlet 211. After passing through the heating system, the heated air is sent into the working chamber of the hopper 20 by the fan, where it exchanges heat with the plastic material to achieve a drying effect.
[0022] In practical implementation, the hopper 20 has a hopper door 22 on its side wall, which is connected to the hopper 20. The bottom of the hopper 20 has a discharge port 23. In use, plastic granules are fed into the working chamber of the hopper 20 through the hopper door 22. The fan heats the air through the heating system and sends it into the working chamber of the hopper 20. The hot air is blown evenly onto the surface of the plastic granules to accelerate the evaporation of moisture. The hot air comes into contact with the surface of the plastic granules, and the moisture is evaporated. Due to the continuous blowing of hot air, the granules are dried evenly. The dried plastic granules are discharged through the discharge port 23, completing the entire drying process.
[0023] In practical implementation, a temperature control box 30 is installed on the mounting bracket 10. The temperature control box 30 is electrically connected to the heating system. A switch bracket 11 is connected to the bottom of the mounting bracket 10. A switch panel 40 is installed on the switch bracket 11. The surface of the switch panel 40 is provided with a switch button 41. In use, the operator presses the switch button 41 on the switch panel 40 to start the power supply of the dryer. The equipment starts to be powered on. The operator sets the parameters on the temperature control box 30 as needed, sets the target drying temperature, and the temperature control box monitors the temperature in the hopper in real time and adjusts the heating system according to the set value to keep the temperature within a suitable range. The heating system starts to heat the air, and the fan blows the heated air into the hopper working chamber and blows it evenly onto the surface of the plastic particles. The temperature control box ensures that the heating system operates within the set temperature range.
[0024] In practical implementation, the upper part of the hopper 20 is provided with an air outlet 24, which is located below the heating air inlet 211. During use, the fan draws in outside air through the heating air inlet 211 and heats it. After the hot air enters the working chamber of the hopper 20, it comes into contact with the surface of the plastic particles and removes moisture. The heated air is cooled down by heat exchange with the particles and then discharged through the air outlet 24 located above the hopper 20 to maintain air circulation.
[0025] In specific implementation, the hopper 20 is made of stainless steel material, the hopper 20 includes an outer insulation barrel 25 and an inner insulation barrel 26, the size of the outer insulation barrel 25 is larger than the size of the inner insulation barrel 26, the inner insulation barrel 26 is installed inside the outer insulation barrel 25, in use, the outer insulation barrel 25 reduces heat loss by insulating external temperature, ensures that hot air in the inner insulation barrel 26 can be kept at a relatively stable temperature, the inner insulation barrel 26 flows hot air generated by the heating system in the hopper, helps plastic particles to be uniformly dried, the double-layer structure of the inner and outer barrels makes the transmission of hot air more efficient, reduces the burden of the heating system through double insulation, improves the overall drying efficiency, the design of the insulation layer can reduce the energy consumption of the heating system, thereby improving the energy efficiency of the equipment.
[0026] In specific implementation, the surface of the material cover 21 is provided with a material viewing window 212, the material viewing window 212 is made of transparent material, in use, the inside of the hopper can be observed through the material viewing window 212.
