Description

Technical Field

[0001] This utility model relates to the field of plastic raw material processing, and in particular to a high-speed granulation equipment for plastic raw materials. Background Technology

[0002] During the production of plastic granules, a cutter is added to the plastic extrusion end of the granulator to cut the extruded plastic into granules. However, at this time, the temperature of the plastic granules is high, which makes them prone to sticking together and affecting the production quality of the plastic granules.

[0003] A search revealed that application number "202120577259.8" discloses "a granulation device for making PP plastic granules," which describes "a granulation device, a cooling device, and a vibration device; the cooling device includes four columns, a cooling box, a pump body, a circulation box, a liquid outlet pipe, a condenser pipe, a first air box, and a second air box; the cooling box is fixedly connected between the tops of the four columns; the pump body is fixedly connected to the inner bottom wall of the cooling box; the circulation box is fixedly connected to the inner bottom wall of the cooling box; the liquid outlet pipe is fixedly connected to the top of the pump body; and the condenser pipe is fixedly connected to the top of the liquid outlet pipe." This cooling device rapidly cools the granulated plastic, preventing the plastic granules from sticking together and improving the quality of the granulated plastic.

[0004] However, the above-mentioned granulation device still has some shortcomings in use: the granulated plastic granules are not easy to be discharged quickly, cooled down, and have their surface impurities cleaned quickly, which reduces processing efficiency. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A high-speed granulation device for plastic raw materials, including an extrusion tube;

[0007] A pelletizing assembly is provided at the discharge end of the extrusion tube, and a cooling tank is provided below the discharge end of the extrusion tube.

[0008] The cooling tank has a ring-shaped structure. The upper end of the cooling tank is provided with a feed inlet corresponding to the discharge end of the extrusion tube. A drive motor is provided on the side of the cooling tank away from the feed inlet. An agitator is provided on the rotating shaft of the drive motor. The agitator is located inside the cooling tank. A plastic pellet filter frame is provided on the side of the cooling tank in the direction of rotation of the agitator. A discharge plate is hinged at the upper end of the cooling tank at the plastic pellet filter frame. An impurity filter plate is provided on the side of the plastic pellet filter frame away from the agitator.

[0009] As a further embodiment of this utility model: the discharge end of the extrusion tube is also provided with a feeding plate, and the upper end of the feeding plate is also provided with a cooling water pipe, the water outlet end of the cooling water pipe being positioned relative to the pelletizing assembly.

[0010] As a further embodiment of this invention: the upper part of the cooling tank is provided with multiple overflow pipes, and each overflow pipe is connected to an external water filter.

[0011] As a further embodiment of this utility model: the bottom of the cooling tank is inclined downwards from the side of the inlet to the side of the outlet plate.

[0012] As a further embodiment of this utility model: the bottom of the cooling tank is provided with support feet, and each support foot is provided with a caster wheel at its lower end.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a cooling tank at the lower end of the extrusion tube, the plastic pellets fall into the cooling tank from the feed port, and the drive motor drives the cooling water in the cooling tank to flow through the stirring paddle, thereby moving the plastic pellets to the plastic pellet filter frame. The moving water flow cools and cleans the plastic pellets, and the impurity filter plate can filter impurities in the cooling water, thereby effectively improving the processing efficiency.

[0023] Please see Figure 1-2 A high-speed granulation device for plastic raw materials, including an extrusion tube 1;

[0024] A pelletizing assembly 2 is provided at the discharge end of the extrusion tube 1, and a cooling tank 3 is provided below the discharge end of the extrusion tube 1.

[0025] The cooling tank 3 has a ring structure. The upper end of the cooling tank 3 is provided with a feed port 4 corresponding to the discharge end of the extrusion tube 1. A drive motor 5 is provided on the side of the cooling tank 3 away from the feed port 4. A stirring paddle 6 is provided on the rotating shaft of the drive motor 5. The stirring paddle 6 is located inside the cooling tank 3. A plastic pellet filter frame 7 is provided on the side of the cooling tank 3 in the direction of rotation of the stirring paddle 6. A discharge plate 8 is hinged at the upper end of the cooling tank 3 at the plastic pellet filter frame 7. An impurity filter plate 9 is provided on the side of the plastic pellet filter frame 7 away from the stirring paddle 6.

[0026] In use, the pelletizing assembly 2 pellets the plastic extruded from the extrusion tube 1. The plastic pellets fall from the feed port 4 into the cooling tank 3. The drive motor 5 drives the cooling water in the cooling tank 3 to flow through the stirring paddle 6, thereby moving the plastic pellets into the plastic pellet filter frame 7. The plastic pellet filter frame 7 can be removed by opening the discharge plate 8, thus obtaining the cooled plastic pellets. The moving water flow cools and cleans the plastic pellets, and the impurity filter plate 9 can filter impurities in the cooling water.

[0027] A further solution: The discharge end of the extrusion tube 1 is also provided with a feeding plate 10, and the upper end of the feeding plate 10 is also provided with a cooling water pipe 11, with the water outlet end of the cooling water pipe 11 positioned relative to the pelletizing assembly 2.

[0028] Under the limiting position of the feeding plate 10, the plastic pellets can accurately fall into the cooling tank 3. The cooling water pipe 11 can help the pelletizing assembly 2 cool down, avoid sticking, and at the same time perform preliminary cooling of the plastic pellets.

[0029] A further solution: The upper part of the cooling tank 3 is provided with multiple overflow pipes 12, and each overflow pipe 12 is connected to an external water filter.

[0030] It can prevent the cooling water in the cooling tank 3 from overflowing. The overflowing water is filtered by an external water filter and then cooled before being transferred to the cooling water pipe 11 for reuse.

[0031] A further solution: The bottom of the cooling tank 3 is set to gradually slope downwards from one side of the inlet 4 towards the outlet plate 8.

[0032] This allows the plastic granules to gradually move towards the plastic granule filter frame 7, and under the influence of the water flow, they can move even faster, preventing sedimentation.

[0033] A further solution: The bottom of the cooling tank 3 is provided with support feet 13, and each support foot 13 is provided with a caster wheel 14 at its lower end.

[0034] It allows for easy movement and expands the work area.

[0035] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
