Description

Technical Field

[0001] The utility model belongs to the technical field of air cooling devices, in particular to a granulation air cooling device. Background Art

[0002] A chip granulator, also known as a pelletizer or cutting granulator, is a device used to cut powdered or granular raw materials into particles of the desired size through a specific mechanical action. This type of equipment is needed when producing plastic foot pads. After the chip granulation is completed, an air conveying pipe is needed to transport the particles formed after chipping to the discharge port, and in this process, air cooling is used to cool the particles with higher temperatures after chipping. However, in the existing technology, there is still room for improvement in the cooling efficiency and anti-sticking of the particles. Utility Model Content

[0003] In response to the above problems, the purpose of the present invention is to provide a granulation air cooling device, which can improve the smoothness of the particles being transported toward the discharge pipe during the air cooling process, avoid accumulation, and at the same time improve the efficiency of particle cooling and reduce the possibility of particle adhesion.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a granulation air cooling device comprises an extrusion device, a chip cutting device is provided on one side of the extrusion device, a splash shield is provided between the extrusion device and the chip cutting device, the bottom of the splash shield is connected to one end of a first air duct, the other end of the first air duct is connected to the air supply fan, the top of the splash shield is connected to a connecting pipe, one end of the connecting pipe is connected to the air supply duct, a rotating auxiliary cooling pipe is rotatably installed on the inner side of the air supply duct, spiral blades and flipping paddles are provided on the outer side of the rotating auxiliary cooling pipe, one end of the rotating auxiliary cooling pipe is connected to a rotating joint, the other end of the rotating joint is connected to an air outlet cover, an exhaust fan is installed on the inner side of the air outlet cover, a first bracket is sleeved on the outer side of the air outlet cover, the bottom of the air supply duct is connected to the discharge pipe, a first pulley is provided on the outer side of the air supply duct, a rotating drive motor is provided on one side of the first bracket, the output end of the rotating drive motor is connected to a second pulley, and a belt is connected between the second pulley and the first pulley.

[0005] The beneficial effects of the present invention are as follows: the rotation drive motor drives the second pulley to rotate, and the second pulley drives the first pulley through the belt together with the rotating auxiliary cooling pipe to rotate inside the air delivery pipe through the bearing and the rotating joint. When the rotating auxiliary cooling pipe rotates, the spiral blades and the flipping paddles are driven to rotate, so that the particles inside the air delivery pipe move toward the discharge pipe while the air flow generated by the air delivery fan and the auxiliary air delivery fan can be assisted by the spiral blades to keep the particles in a moving state, thereby avoiding the accumulation of particles inside the air delivery pipe. The air flow inside the air delivery pipe can cool the particles while transporting them, and the exhaust fan is also running at the same time, so that the air flow is drawn in from one end of the rotating auxiliary cooling pipe and discharged from the exhaust fan, and the large-diameter exhaust fan is used. The setting of the fan and the straight rotating auxiliary cooling pipe enables the air flow to pass through the rotating auxiliary cooling pipe in large quantities and quickly. The heat in the air inside the air delivery pipe and the heat in the particles can be transferred to the rotating auxiliary cooling pipe and the spiral blades, and carried away by the fast and large-scale air flow flowing inside the rotating auxiliary cooling pipe, thereby improving the efficiency of particle cooling. Since a flipping paddle is provided, the particles inside the air delivery pipe can be beaten and stirred, which improves the uniformity of particle cooling and reduces the possibility of adhesion between particles. The cooled particles are discharged through the discharge pipe and can be collected in a container. In summary, this device can improve the smoothness of the particles conveyed toward the discharge pipe during the air cooling process, avoid accumulation, and at the same time improve the efficiency of particle cooling and reduce the possibility of particles sticking together.

[0006] To increase airflow:

[0007] As a further improvement of the above technical solution: a second air duct is connected to the side of the connecting pipe, and the other end of the second air duct is connected to the auxiliary air supply fan.

[0008] The beneficial effect of this improvement is that the auxiliary air supply fan is used to help the device enhance the air flow, help the particles enter the interior of the air supply pipe, and move the particles toward the discharge pipe.

[0009] In order to turn over the particles inside the air delivery duct:

[0010] As a further improvement of the above technical solution: the flipping paddles are provided in two rows, upper and lower, and are arranged at even intervals.

[0011] The beneficial effect of this improvement is that the turning paddles are provided in two rows, upper and lower, which can effectively turn over the particles inside the air delivery duct.

[0012] In order to reinforce the air delivery pipeline:

[0013] As a further improvement of the above technical solution: a third bracket is installed at the bottom of the air supply duct.

[0014] The beneficial effect of this improvement is that the third bracket is used to reinforce and support the air delivery duct.
