TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic processing, especially relates to a granulating device for recycled plastic particle processing. BACKGROUND
[0002] The granulating device for recycled plastic particle processing is a general term for a kind of equipment specially used to reprocess waste plastic materials into granular new plastics. These granular new plastics can be widely used to produce various plastic products, such as automobile parts, furniture, building materials, packaging materials, etc., thereby realizing effective recycling of waste plastics and reducing resource waste.
[0003] The existing granulating device for recycled plastic particle processing mostly adopts water spraying cooling method when cooling the melted plastic, which may result in uneven cooling effect. Due to the flowability and uneven distribution of water, some plastic particles may be cooled too quickly, while others may not be cooled enough. Such uneven cooling effect may affect the quality and performance of the plastic particles. SUMMARY
[0004] The utility model discloses a granulating device for recycled plastic particle processing, which can quickly cool and fix the melted plastic for forming, thereby solving the problem of inconvenient quick cooling and fixing of the melted plastic in the prior art.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0006] A granulating device for recycled plastic particle processing includes a shell, a spiral blade rotatably connected inside the shell, a cavity provided inside the shell, a plurality of pipes arranged in an annular array inside the shell, the middle section of the pipe located inside the cavity, a column rotatably connected to the side wall of the shell, two cutters fixedly connected to the side wall of the column, and the cutter side wall and the shell side wall are attached; a cooling box is provided on the side wall of the shell, a water pump is fixedly connected to the upper end of the cooling box, the input end of the water pump is in communication with the inside of the cooling box, a conveying pipe is provided between the output end of the water pump and the inside of the cavity, and a reflux pipe is provided between the inside of the cooling box and the inside of the cavity.
[0007] Preferably, an inlet cylinder is fixedly connected to the upper end of the shell, and the inlet cylinder is in communication with the inside of the shell.
[0008] Preferably, a driving motor is fixedly connected to the side wall of the shell, a horizontal rod is rotatably connected inside the shell, the end of the horizontal rod is fixedly connected to the output end of the driving motor, and the horizontal rod is fixedly connected to the spiral blade.
[0009] Preferably, a motor is fixedly connected inside the inner sidewall of the housing, and the output end of the motor is fixedly connected to the end of the column.
[0010] Preferably, two coolers are fixedly connected through the side wall of the cooling box, and the cooling end of the cooler is located inside the cooling box.
[0011] Preferably, a circular plate is threaded to the lower end of the cooling box, a filter cartridge is fixedly connected to the upper end of the circular plate, one end of the return pipe is fixedly connected to the circular plate through it, and the port of the return pipe is located inside the filter cartridge.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] 1. A drive motor drives a crossbar to rotate, which in turn drives a spiral blade. The rotating spiral blade pushes molten plastic from one end of the pipe into the pipe. The molten plastic is squeezed inside the pipe, and a water pump and delivery pipe transport coolant from inside the cooling tank to the cavity. The coolant inside the cavity exchanges heat evenly with the side wall of the pipe, causing the plastic inside the pipe to be squeezed, cooled, and solidified. The solidified plastic is then discharged from the other end of the pipe. Subsequently, a motor drives a column to rotate, which in turn drives a cutter to granulate the shaped plastic, thus granulating the recycled plastic. By rapidly cooling and solidifying the molten plastic inside the pipe, production efficiency is improved.
[0014] 2. The negative pressure drawn into the cooling tank by the water pump causes the coolant that has undergone heat exchange inside the chamber to flow back to the filter cartridge through the return pipe. The filter cartridge filters the coolant to keep it pure. The purified coolant then flows back into the cooling tank, where the cooler recools the returned coolant. The filtration by the filter cartridge removes impurities and particles from the coolant, ensuring its purity and extending its service life. Attached Figure Description
