Technical Field

[0001] The utility model relates to the field of TPV production, in particular to a TPV underwater pelletizing return water filtering device. Background Art

[0002] In the production process of TPV (thermoplastic vulcanizate) materials, underwater pelletizing is a commonly used processing method. An underwater pelletizer is used to cut the molten rubber and plastic materials extruded through the template into particles in process water. The cut particles flow into the particle separator along with the process water. The process water returns to the recovery pool through the particle separator. In order to improve the utilization rate of water resources, the process water is usually recycled. However, the process water will carry fine particles, residual materials and other impurities produced by cutting. These impurities need to be filtered, intercepted and removed to prevent them from entering the pelletizing area again, affecting the slicing quality and causing equipment wear.

[0003] The existing TPV underwater pelletizing return water filtration device passes the process water separated by the particle separator into the filter tank for secondary filtration, removes the fine particles and residual materials in the process water, and then flows into the recovery tank for recycling. However, due to the process water being circulated, the temperature of the process water will gradually increase, affecting the pelletizing effect and product quality.

[0004] Therefore, a TPV underwater pelletizing return water filtration device is now developed, which can cool the process water during the process water circulation filtration to avoid the temperature increase of the process water during the circulation use. Utility Model Content

[0007] Furthermore, it also includes a flange, and the left and right parts of the rotary filter tube are both rotatably connected with the flange.

[0008] Furthermore, a water outlet groove is provided between the fixed tube and the rotary filter tube.

[0009] Furthermore, the feeding assembly includes a motor, a first gear and a second gear. The motor is connected to the lower right side of the fixed tube, the first gear is connected to the motor output shaft, the second gear is connected to the right side of the rotating filter tube, and the second gear is meshed with the first gear.

[0010] Furthermore, the cooling assembly includes a connecting pipe, a heat dissipation fin and a fan. The lower side of the water outlet pipe is connected to a connecting pipe, the lower side of the connecting pipe is also connected to a flange, the rear side of the connecting pipe is connected to a heat dissipation fin, and a plurality of fans are rotatably connected to the heat dissipation fin.
