Description

Technical Field

[0001] This utility model relates to the field of granulation and drying equipment, and in particular to a waste plastic granulation and drying equipment. Background Technology

[0002] Waste plastic pelleting technology is an important resource recycling technology. Waste plastics mainly come from daily life, industrial production, and agriculture. Through specific processes, they are transformed into recycled plastic pellets. These recycled pellets can replace some of the virgin materials in the production of various plastic products, thereby saving raw material costs, reducing production costs, and helping to reduce the pollution of waste plastics to the environment, thus realizing the recycling of resources.

[0003] However, existing waste plastic pelleting requires water cooling for rapid shaping and then natural air drying, which takes a longer time to remove moisture. Moreover, moisture is less likely to evaporate from the accumulated plastic pellets, which greatly affects the quality of the waste plastic pellets.

[0004] Therefore, to address the issues of long drying time and unsatisfactory results after granulation of waste plastics, a waste plastic granulation and drying device can be designed. Utility Model Content

[0005] To overcome the problem of long drying time and unsatisfactory results after waste plastic granulation.

[0006] The technical solution of this utility model is as follows: a waste plastic granulation and drying device, including a cold water tank, a filter screen barrel, a feeding channel, a granulator, a pushing cylinder, a support frame, an air outlet, a mounting plate, and a stirring component; a filter screen barrel for holding plastic granules is slidably connected to the inside of the cold water tank; a feeding channel with a guiding structure is provided at the upper end of the cold water tank; the upper end of the feeding channel is connected to the granulator outlet; a pushing cylinder for pushing the filter screen barrel upward is installed at the lower end of the cold water tank; a support frame is welded to the outside of the cold water tank; an air outlet for drying the plastic granules inside the filter screen barrel is fixedly connected to the upper end of the support frame; a mounting plate is fixedly connected to the upper end of the filter screen barrel; a stirring component for turning the plastic granules is installed at the upper end of the mounting plate.

[0007] Preferably, in the first step, before starting the device, an appropriate amount of cold water is pre-filled into the cold water tank. After a series of pretreatments, the waste plastic raw materials are sent to the granulator for granulation. The granulator processes the plastic raw materials into uniformly sized plastic granules. The newly produced plastic granules slide smoothly into the filter screen barrel through the granulator's outlet along the feed channel with a guide structure, achieving rapid cooling and shaping.

[0008] The second step is that the agitator located at the top of the mounting plate starts to work. The rotating motor drives the agitator shaft to rotate, and the rotating agitator blades agitate the plastic particles in the filter screen bucket.

[0009] The third step is to start the cylinder after granulation is completed, pushing the filter screen and the plastic particles inside upward to the inside of the air outlet.

[0010] The fourth step involves the air outlet blowing hot air or dry air at room temperature to dry the plastic particles in the filter bucket that are being stirred by the agitator.

[0011] Fifth step: After drying is complete, push the cylinder to move again, lower the discharge port of the filter screen barrel to the gap between the support frame, and open the discharge port to discharge the material.

[0012] Preferably, the piston rod of the cylinder is connected to the bottom of the filter screen barrel; a symmetrical sliding sleeve is fixedly connected to the inside of the filter screen barrel; a limiting slide rod that matches the position of the sliding sleeve is fixedly connected to the inside of the cold water tank; the sliding sleeve and the limiting slide rod are slidably connected.

[0013] Preferably, the air outlet component includes a fan, an air duct, and an air outlet; the fan is fitted and connected to the rear end of the air duct; and an air outlet with an annular structure is connected to the inner side of the air duct.

[0014] Preferably, the filter screen barrel has a discharge port on its side for easy discharge of dried plastic granules; a door panel is hinged to the inside of the discharge port.

[0015] Preferably, the mixing component includes a rotating motor, a mixing shaft, and a stirring blade; the mixing shaft is installed at the lower end of the output shaft of the rotating motor; and the stirring blade is welded to the outside of the mixing shaft.

[0016] Preferably, the height of the upper edge of the filter screen barrel is lower than the height of the discharge port of the feed channel.

[0017] Preferably, the inner diameter of the air outlet component should be larger than the outer diameter of the filter screen barrel.

[0018] The beneficial effects of this utility model are:

[0019] This invention allows newly manufactured plastic granules to slide smoothly into a filter screen barrel through the granulator's outlet along a feed channel with a guide structure. The granules come into direct contact with the cold water stored in the cold water tank, achieving rapid cooling and shaping, effectively preventing granule deformation or adhesion, and ensuring granule uniformity and quality. Throughout the granulation process, the stirring component agitates the plastic granules within the filter screen barrel. This step not only promotes airflow between granules but also enhances the cooling effect. Furthermore, the subsequent air outlet helps remove surface contaminants from the granules during drying, improving drying efficiency. By integrating multiple steps into one device, labor intensity is reduced, and production efficiency is increased. Attached Figure Description
