Description

Technical Field

[0001] This utility model relates to the field of plastic recycling, specifically a plastic recycling grinding device. Background Technology

[0002] The recycling and reuse of waste plastics has been widely adopted by modern chemical enterprises. After manual screening and sorting, waste plastics undergo processes such as crushing, granulation, and modification to become various transparent and opaque plastic granules. These granules are then classified according to their quality and finally become reusable recycled materials.

[0003] Current plastic recycling grinding equipment, as described in patent CN212826298U, includes a housing with a discharge port; the housing is vertically arranged and a grinding seat is fixed inside the housing; the upper surface of the grinding seat is formed as a first grinding surface, and a grinding head is rotatably arranged above the grinding seat; the lower end of the grinding head is formed as a second grinding surface, and the upper end of the grinding head extends out of the housing and is connected to a drive mechanism that drives its rotation; a feeding channel is opened on the grinding head, the lower end of the feeding channel penetrates through the second grinding surface, and the upper end of the feeding channel penetrates through the upper end face of the grinding head and is connected to a feed hopper.

[0004] Regarding the aforementioned technologies, the inventors believe that grinding plastic on a grinding base by rotating the grinding head generates a large amount of heat due to friction during grinding, causing the temperature of the grinding head to rise continuously. This high temperature can easily cause the plastic being ground to melt, thereby reducing the grinding effect on the plastic. Utility Model Content

[0005] The purpose of this invention is to provide a plastic recycling and grinding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The motor 109 is used to drive the drive gear 110, the driven gear 108 and the shaft tube 104 to rotate when the machine is started.

[0025] Cooling mechanism 2 includes an upper rotary joint 201 that is fixedly connected to the top of the shaft tube 104. A connecting pipe 203 is fixedly connected to the end of the upper rotary joint 201 away from the shaft tube 104. The connecting pipe 203 is used to guide heat transfer oil into the interior of the shaft tube 104. A support plate 202 is fixedly connected to the outside of the connecting pipe 203. The support plate 202 is fixedly connected to the horizontal plate 107 and provides auxiliary support for the connecting pipe 203.

[0026] A lower rotary joint 204 is fixedly connected to the bottom of the rotating tube 105. A first pump 205 is fixedly connected to the end of the lower rotary joint 204 away from the rotating tube 105. A liquid extraction pipe 206 is fixedly connected to the output end of the first pump 205. The first pump 205 is configured to draw the heat transfer oil inside the rotating tube 105 and the grinding disc 103 into the liquid extraction pipe 206 during startup. A receiving groove 216 is rotatably connected to the outside of the rotating tube 105. The receiving groove 216 is fixedly connected to the grinding box 101 and is configured to catch the plastic powder discharged from the grinding box 101.

[0027] Multiple first heat exchange tubes 207 are uniformly and fixedly connected between the liquid extraction tube 206 and the connecting tube 203. The first heat exchange tubes 207 are configured to allow the heat transfer oil inside the liquid extraction tube 206 to drain into the interior of the connecting tube 203. Multiple fins 215 are uniformly and fixedly connected through the outer side of the first heat exchange tubes 207. A support column 214 is fixedly connected to one side of each group of fins 215 to support the fins 215.

When the second pump 210 starts working, it can make the heat transfer oil inside the spiral flow channel 208, the guide pipe 211, the second heat exchange pipes 212 and the connecting pipe 209 circulate, so that the flowing heat transfer oil can carry away the heat in the grinding base 106.

[0029] In this embodiment, the upper rotary joint 201 and the lower rotary joint 204 are existing technologies and will not be described in detail here.

[0030] In use, the motor 109 is started, which drives the drive gear 110, driven gear 108, shaft tube 104, and grinding disc 103 to rotate. The plastic to be ground is then fed into the hopper 102, falling into the grinding chamber 101. As the material moves between the grinding seat 106 and the grinding disc 103, it is ground by the rotating grinding disc 103. Finally, the material is discharged from the grinding chamber 101 onto the receiving trough 216. The heat generated during the grinding of the plastic by the grinding disc 103 is transferred to the heat-conducting oil inside the grinding disc 103, and the heat from the grinding seat 106 is transferred to the heat-conducting oil inside the spiral flow channel 208. Then, the first pump 205 can be started. The second pump 210 and fan 213 enable the first pump 205 to circulate the heat transfer oil inside the grinding disc 103, rotating tube 105, liquid extraction tube 206, first heat exchange tube 207, connecting tube 203, and shaft tube 104 when the first pump 205 starts working. The second pump 210 enables the heat transfer oil inside the spiral flow channel 208, guide tube 211, second heat exchange tube 212, and connecting tube 209 when the second pump 210 starts working. The fan 213 can provide air cooling for the heat transfer oil flowing through the first heat exchange tube 207 and the second heat exchange tube 212, thereby cooling the grinding disc 103 and grinding base 106 and reducing the probability of the grinding plastic melting due to excessive temperature of the grinding disc 103 and grinding base 106.
