Description

Technical Field

[0001] The invention relates to the field of plastic powder processing, in particular to a drying device for plastic powder processing which is beneficial to uniform heating. Background Art

[0002] Plastic powder is the material for the plastic spraying process. Simply put, plastic powder is heated at high temperature and then sprayed onto the surface of the material through compressed air. Before the plastic powder is used, it needs to be dried to prevent the plastic powder spraying from failing to achieve the expected effect. Therefore, a drying device is needed.

[0003] According to the public patent 202221269455.X, a drying device for plastic powder processing that facilitates uniform heating includes a base and a filtering mechanism, a silo is fixedly connected to the top of the base, and a cone bucket is connected to the top of the silo, a filtering mechanism is installed in the middle of the cone bucket, and a vibration motor is installed inside the filtering mechanism, a material barrel is connected to the top of the cone bucket, and a drying mechanism is connected to one side of the cone bucket, a large cover is installed on the top of the material barrel, and an exhaust port is provided on the large cover, the end of the exhaust port is connected to a return air pipe, and the other end of the return air pipe is connected to the drying mechanism. The drying device for plastic powder processing is conducive to uniform heating. A sieve is installed in the sieve plate, and the plastic powder raw material is added above the sieve. After being heated and semi-dried, the plastic powder will fall into the cone bucket through the sieve under the vibration of the vibration motor for more uniform heating. The vibration motor is used to help filter the plastic powder, which can improve the filtration efficiency and make it difficult to leave the raw material on the drying net. In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: although a sieve is installed in the sieve plate, the plastic powder raw material is added above the sieve. After being heated and semi-dried, the plastic powder will fall into the cone bucket through the sieve under the vibration of the vibration motor for more uniform heating, and the vibration motor is used to help filter the plastic powder. Powder, can improve the efficiency of filtration, and finally it is not easy to leave raw materials on the drying net. It solves the problem that the plastic powder drying device on the market directly discharges the heated hot air, causing waste, and the raw materials in the barrel are not easy to handle cleanly. However, during use, the traditional plastic powder processing uses a drying device that is conducive to uniform heating. A hot air blower is used to dry the plastic powder. Since the plastic powder is piled together, the hot air is not very effective in drying the center of the plastic powder pile, resulting in inconsistent drying effects at different positions of the plastic powder. Moreover, the waste heat is utilized by re-transferring the hot air to the hot air blower. This method only repeats the drying of the waste heat and does not fully utilize the heat of the waste heat. For this reason, a new technical solution needs to be designed to provide a solution. Summary of the invention

At the same time, since the water is heated and circulated to dry the plastic powder, the staff can use the hot water, thereby utilizing the new purpose of waste heat. After the hot water enters the rotating tube 2 and the main drying tube 201, it will continue to enter the circulation box 204. When hot water circulation drying is required, the second water pump 205 needs to be turned on. The second water pump 205 will draw out the hot water in the circulation box 204, and re-input the hot water into the bottom shell 209 of the device through the L-shaped tube body 206 to realize circulation.
