Description

Technical Field

[0001] The utility model belongs to the technical field of plastic powder, and in particular relates to an air cooling device for plastic powder production. Background Art

[0002] Plastic powder is a main material for plastic spraying process. Its components are a mixture of resin, pigment, additives and fillers. In the production process of plastic powder, it needs to go through mixing, flaking, crushing and other processes to obtain the finished plastic powder. In the crushing process, we need to use a crusher to grind a variety of materials. During the operation of the crusher, a large amount of heat energy will be generated due to the mutual friction between the crushing rollers. When processing the heat, an air cooling device is required.

[0003] During operation, the existing air cooling device introduces external air into the interior of the pulverizing mechanism and outputs it from the heat dissipation port of the pulverizing mechanism to achieve the purpose of heat dissipation. However, since the external air is DC air when it is introduced, it is impossible to ensure that the airflow enters the interior of the pulverizing mechanism evenly, resulting in poor heat dissipation effect. Secondly, during the heat dissipation process, the airflow can easily carry away the plastic powder particles inside the pulverizing mechanism and discharge them into the air, causing pollution to the atmosphere. Therefore, we provide an air cooling device for plastic powder production. Utility Model Content

Through the setting of the heat dissipation port, with the cooperation of the air cooling mechanism, the heat inside the crushing box 1 is quickly discharged to achieve the purpose of efficient heat dissipation. At the same time, because the No. 2 fine filter is provided inside the heat dissipation port, it can prevent the plastic powder particles from being transported to the external air with the air flow and causing air pollution. When it is necessary to dissipate the heat of the inner cavity of the crushing box 1, the fan 4 is started, and the external air is sucked in by the fan 4 with the cooperation of the connecting pipe. The air is transported to the inner cavity of the filter box 5 through the air inlet cover and the air guide pipe, and is passed through The No. 3 fine filter 6 filters the dust in the air to improve the cleanliness of the air. After the purification is completed, the gas is transported to the inner cavity of the crushing box 1 through the connecting pipe and the air outlet pipe.

After purification, the gas is transported to the inner cavity of the crushing box 1 through the connecting pipe and the air outlet pipe. When the airflow passes through the fan blade 8, the airflow can drive the fan blade 8 to rotate, thereby driving one end of the rotating rod to rotate on the inner ring of the bearing through the fan blade 8, so that the direct wind becomes diffused wind, which can evenly export the heat inside the crushing box 1, greatly improving the heat dissipation effect. At the same time, because the inner cavity of the heat dissipation port on the right side of the crushing box 1 is provided with a No. 2 fine filter, it can prevent the plastic powder particles from being transported to the external air with the airflow and causing pollution to the air. Finally, the control valve is turned to allow the particles to be transported to the external collection box through the discharge pipe.
