Description

Technical Field

[0001] This utility model relates to the field of elastic granule production technology, and in particular to a cooling device at the discharge end for elastic granule production. Background Technology

[0002] Elastic granules are materials that exhibit rubber-like elasticity at room temperature, such as polyolefin thermoplastic elastomers. These materials are characterized by low density, high flexural strength, high low-temperature impact resistance, ease of processing, and reusability, making them widely used in industries such as automotive manufacturing. However, during the production of elastic granules, the extruded material is at a relatively high temperature. To facilitate subsequent storage and processing, cooling treatment is necessary. However, existing cooling devices for elastic granules still have some problems in use:

[0003] 1. In the existing process of cooling elastic granules, there is still a lot of granules accumulating together. Because the elastic granules are accumulating together, the cooling air cannot effectively contact them, thus failing to cool them sufficiently, resulting in poor overall cooling effect.

[0004] 2. In the current process of cooling elastic granules, most of them only use air cooling flow. However, as time goes by, the surrounding air temperature rises, which leads to a gradual decrease in the subsequent cooling efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling device for the discharge end of elastic granule production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cooling device for the discharge end of an elastic granule production process includes a cylindrical shell. One end of the cylindrical shell has an inner wall connected to a feed pipe, and a convex bottom shell is screwed to the inner wall of the bottom of the cylindrical shell. The bottom of the convex bottom shell has equidistantly distributed guide pipes around its perimeter. A sealing cover is fixed to the outer wall of the top of the cylindrical shell via a snap-lock. A drive motor is connected to the top axis of the sealing cover, and a stirring rod is connected to the output shaft of the drive motor. A cooling shell with a circular through-slot is slidably inserted into the bottom of the guide pipes. A water inlet pipe is connected to the top of one inner wall of the cooling shell, and a drain pipe is connected to the bottom of the other inner wall of the cooling shell.

[0008] As a further improvement of this utility model: a rectangular air intake pipe is connected to the top side of the sealing cover, and an air intake fan is fixed to the inner wall of the rectangular air intake pipe by screws.

[0009] As a further improvement of this utility model: the inner walls of the cylindrical shell are perforated with equally spaced exhaust slots, and the inner walls of the exhaust slots are all glued with filter screens.

[0010] As a further improvement of this utility model: a sealing collar is screwed onto the inner top wall of the cooling shell, and the sealing collar forms a tight fit with the cylindrical shell.

[0011] As a further improvement of this utility model: a stirring blade is rotatably provided at the bottom axis of the cooling shell, and a servo motor is connected to the bottom outer wall of the stirring blade via a coupling.

[0012] As a further improvement of this utility model: the material guiding pipe is provided with heat-conducting fins that are evenly distributed on all four outer walls of the cooling shell, and the outer walls of the heat-conducting fins are provided with heat dissipation grooves that are evenly distributed.

[0013] As a further improvement of this utility model: the spacing between the material guiding pipes is adapted to the size of the stirring blades, and the length of the stirring blades is adapted to the depth of the inner wall of the cooling shell.

[0014] Compared with the prior art, this utility model provides a cooling device for the discharge end of elastic granule production, which has the following beneficial effects:

[0015] 1. In the initial stage of cooling treatment, the elastic granules in this design are cooled by directly blowing cold air through an air intake fan. In order to reduce the heat accumulation in the gaps, a continuously rotating stirring rod is used to agitate the granules, thereby accelerating the cooling process.

[0016] 2. The elastic granule cooling device designed in this paper, after initially cooling the elastic granules with air, evenly passes them through the interior of the guide pipe. Meanwhile, continuously flowing cold water is installed on the outer wall of the middle part of the guide pipe to continuously treat the interior of the guide pipe at a low temperature. Thus, the elastic granules passing through can transfer heat, achieving rapid and uniform cooling. Furthermore, the bottom is equipped with stirring blades to make the cold water temperature distribution more uniform, thereby improving the cooling effect.

[0017] 3. The elastic granule cooling device of this design uses a drive motor to continuously rotate the stirring rod when the elastic granules are uniformly passed through the inside of the guide pipe, thereby avoiding the accumulation of elastic granules that prevent them from smoothly passing through the inside of the guide pipe.

[0018] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1:

[0026] A cooling device at the discharge end for producing elastic granules, in this embodiment, as follows: Figure 1-4 As shown, the device includes a cylindrical shell 1, with a feed pipe 2 connected to the inner wall of one end of the cylindrical shell 1, and a convex bottom shell 3 screwed to the inner wall of the bottom of the cylindrical shell 1. The bottom of the convex bottom shell 3 is connected to the four sides of the bottom of the convex bottom shell 3, with equally spaced guide pipes 4. The top outer wall of the cylindrical shell 1 is fixed with a sealing cover plate 5 by a snap lock. The top axis of the sealing cover plate 5 is connected to a drive motor 6, and the output shaft of the drive motor 6 is connected to a stirring rod 7. The bottom of the guide pipe 4 is slidably inserted into a cooling shell 13 with a circular through groove 12. The top of one inner wall of the cooling shell 13 is connected to a water inlet pipe 15, and the bottom of the other inner wall of the cooling shell 13 is connected to a drain pipe 16.

[0027] In the initial stage of cooling treatment, the elastic granules are cooled by directly blowing cold air through the intake fan 9. In order to reduce the heat accumulation in the gaps, the continuously rotating stirring rod 7 is used to agitate them, thereby accelerating the cooling treatment of the elastic granules.

[0028] The top side of the sealing cover plate 5 is connected to a rectangular air intake pipe 8, and the inner wall of the rectangular air intake pipe 8 is fixed with an air intake fan 9 by screws. The inner walls of the cylindrical housing 1 are perforated with equally spaced exhaust slots 10, and the inner walls of the exhaust slots 10 are all glued with filter screens 11.

[0029] A sealing ring 14 is screwed onto the top inner wall of the cooling shell 13, and the sealing ring 14 forms a tight fit with the cylindrical shell 1.

[0030] A stirring blade 17 is rotatably mounted at the bottom axis of the cooling housing 13, and a servo motor 18 is connected to the bottom outer wall of the stirring blade 17 via a coupling.

[0031] After the elastic granules are initially cooled by air cooling, they are evenly passed through the interior of the feed pipe 4. Meanwhile, continuously flowing cold water is installed on the outer wall of the middle part of the feed pipe 4 to continuously treat the interior of the feed pipe 4 at a low temperature. This allows the elastic granules to transfer heat and achieve rapid and uniform cooling. Furthermore, the bottom is equipped with stirring blades 17 to make the cold water temperature distribution more uniform, thereby improving the cooling effect.

[0032] In this embodiment, the cooling device is first assembled, and the feed pipe 2 is connected to the external discharge port. The interior of the cooling shell 13 is filled with flowing cold water. After that, the elastic granules that need to be cooled are fed into the interior of the cylindrical shell 1 through the feed pipe 2. At this time, the top air intake fan 9 is turned on to blow external cold air into the interior of the cylindrical shell 1. The drive motor 6 drives the stirring rod 7 to rotate continuously, thereby loosening the elastic granules and performing preliminary cooling. After the preliminary cooling, the continuously rotating stirring rod 7 allows the elastic granules to pass smoothly into the guide pipe 4. The continuously flowing cold water lowers the temperature of the guide pipe 4. Through heat transfer, the high-temperature elastic granules are cooled and discharged from the bottom of the guide pipe 4.

[0033] Example 2:

[0034] A cooling device at the discharge end for the production of elastic granules, such as Figure 1-4 As shown, this embodiment makes the following additions based on embodiment 1: the material guiding pipe 4 is welded with heat-conducting fins distributed at equal intervals on all four outer walls of the cooling shell 13, and the outer walls of the heat-conducting fins are provided with heat dissipation grooves distributed at equal intervals. The spacing between the material guiding pipes 4 is adapted to the size of the stirring blade 17, and the length of the stirring blade 17 is adapted to the depth of the inner wall of the cooling shell 13.

[0035] In this embodiment, when the elastic granules are uniformly passed through the inside of the guide pipe 4, the drive motor 6 drives the stirring rod 7 to rotate continuously, thereby avoiding the accumulation of elastic granules that prevent them from smoothly passing through the inside of the guide pipe 4.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
