Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] Refer to Figure 1 、 Figure 4 and Figure 5, an embodiment provided by the present utility model: a countercurrent cooling device for a granulator with an adjustable material spreader, comprising a bracket 1, a cooling tank 2 is fixedly connected to the middle of the bracket 1, an extension plate 5 is fixedly connected to the left side of the outside of the bracket 1, a controller 6 is installed on the upper part of the extension plate 5, a motor 8 is arranged on the left side of the outside of the cooling tank 2, the motor 8 is electrically connected to the controller 6, the output end of the motor 8 is fixedly connected to a rotating rod 9, the rotating rod 9 is rotatably connected to the cooling tank 2, two cam 10 are fixedly connected to both sides of the outside of the rotating rod 9, a material spreader plate 11 is arranged above the two cams 10, two guide blocks 12 are fixedly connected to both sides of the outside of the material spreader plate 11, two guide rods 13 are fixedly connected to both sides of the inside of the cooling tank 2, two springs 14 are sleeved on the outside of the two guide rods 13, the two guide blocks 12 are slidably connected to the outside of the two guide rods 13, a mounting plate 16 is fixedly connected to the bottom of the cooling tank 2, two cooling fans 17 are installed on both sides of the inside of the mounting plate 16, a collection assembly 18 is arranged on the upper right side of the bracket 1, the collection assembly 18 is used for collecting the powder generated during material spreading, a mounting ring 7 is fixedly connected to the left side of the outside of the cooling tank 2, the motor 8 is fixedly connected to the inside of the mounting ring 7, mounting grooves 15 are opened on both sides of the inside of the cooling tank 2, the two guide rods 13 are fixedly connected to the inside of the two mounting grooves 15, a feed inlet 3 is fixedly connected to the upper left side of the cooling tank 2, and a discharge outlet 4 is fixedly connected to the front side of the outside of the cooling tank 2.
[0028] When cooling the particles, first, pour the particles into the interior of the cooling tank 2 through the feed port 3. The particles gradually settle downward from the top under the action of gravity. At the same time, start two cooling fans 17. The cooling fans 17 blow cold air into the tank from the bottom or side of the cooling tank 2 upward by a strong air flow. Since the particles in the cooling tank 2 fall from top to bottom, while the cold air flows from bottom to top, a countercurrent cooling design is formed. This countercurrent cooling design enables the particles to gradually contact the low-temperature cold air during the falling process. The temperature of the air gradually rises, while the temperature of the particles gradually decreases, thereby achieving efficient heat exchange and enabling the particles to be cooled quickly and evenly. When the particles fall on the upper part of the material spreading plate 11, agglomerates are formed due to the viscosity between the particles or the characteristics of the particles themselves, resulting in poor cooling effect. To avoid this situation, start the motor 8 at the same time. The motor 8 drives the rotation through the rotating rod 9 fixed to its output end. The rotation of the rotating rod 9 simultaneously drives the cams 10 fixed on both sides of its outer part. The rotation of the two cams 10 causes the material spreading plate 11 arranged in the upper part to move up and down reciprocally along the vertical direction. The up and down movement of the material spreading plate 11 can break up the particles falling on its surface, especially those that have already agglomerated, so that the particles can be more evenly distributed on the material spreading plate 11. This breaking-up process increases the contact area between the particles and the cold air, significantly improving the cooling efficiency. Through continuous up and down movement, the material spreading plate 11 disperses the particles into finer and more uniform parts, enabling the cold air to more effectively carry away the heat in the particles and promoting the rapid dissipation of heat. This not only shortens the cooling time but also ensures that the cooling of the particles is more uniform, avoiding product quality problems caused by insufficient local cooling. After being sufficiently cooled, the cooled particles continue to fall under the action of gravity and finally are discharged from the discharge port 4 arranged on the front side outside the cooling tank 2. The entire process can be precisely controlled by the controller 6. In particular, the rotation speed of the motor 8 can be adjusted through the controller 6, thereby adjusting the moving speed of the material spreading plate 11. By adjusting the moving speed of the material spreading plate 11, it is possible to adapt to different types of particles and production conditions, further optimizing the cooling effect, achieving the purpose of facilitating the breaking-up of the particles falling on the upper part of the material spreading plate 11 when cooling the particles. In this way, by breaking up the particles, not only the cooling efficiency is improved, but also the stability and reliability of the cooling process are ensured, thus providing a guarantee for the production of high-quality particle products.
[0029] Refer to Figure 2 and Figure 3, the collection component 18 includes a collection box 1801, which is fixedly connected to the upper right side of the bracket 1. The rear side of the outside of the collection box 1801 is fixedly connected with an installation shell 1803. A collection fan 1805 is installed inside the installation shell 1803. A heat dissipation net 1806 is installed on the right side inside the installation shell 1803. A drawer 1802 is slidably connected inside the collection box 1801. One end of a delivery pipe 1807 is fixedly connected to the upper part of the collection box 1801. A collection hood 1808 is arranged on the upper right side of the cooling tank 2. The other end of the delivery pipe 1807 is fixedly connected inside the collection hood 1808. A filter screen 1804 is inserted inside the installation shell 1803. Both sides of the outside of the collection hood 1808 are fixedly connected with installation rods 19. The bottoms of the two installation rods 19 are fixedly connected to both sides of the upper part of the cooling tank 2. A fixed block 20 is fixedly connected to the right side of the outside of the cooling tank 2. The delivery pipe 1807 passes through the inside of the fixed block 20.
[0030] During the process of bulk material scattering of the particles, in order to effectively collect the powder generated during the scattering, by starting the collection fan 1805, using its strong suction force, the powder generated during the bulk material scattering process is captured and inhaled through the collection hood 1808. The collection hood 1808 is installed above the cooling tank 2 and can cover the entire feed port 3, so as to maximize the collection of powder particles escaping into the air during the bulk material scattering process. After being inhaled by the collection hood 1808, these powders are transported through the delivery pipe 1807. The delivery pipe 1807 is responsible for transporting the collected powder from the bulk material scattering area to the inside of the collection box 1801. The collection box 1801 is used to store the collected powder. When the inside of the collection box 1801 is filled with powder, the drawer 1802 can be taken out from the inside of the collection box 1801. The drawer 1802 filled with powder is taken out from the inside of the collection box 1801. The taken-out powder can be directly used for reprocessing or reuse, thus improving the utilization rate of raw materials, reducing the possible waste generated during the production process, and further reducing the overall production cost. The function of setting the filter screen 1804 is to preliminarily filter the inhaled powder and block larger particles or impurities from entering the collection fan 1805. This design effectively prevents the wear or blockage of the fan caused by inhaling too much powder or impurities, extends the service life of the collection fan 1805, and reduces the frequency and cost of equipment maintenance.
[0031] Working principle: When cooling the particles, first, pour the particles into the interior of the cooling tank 2 through the feed port 3. Then, start the two cooling fans 17, and blow the gas upward from the bottom through the two cooling fans 17. Since the particles in the cooling tank 2 fall from top to bottom, while the cold air flows from bottom to top, this design realizes countercurrent cooling. When the particles fall on the upper part of the bulk material plate 11, at the same time, start the motor 8. The motor 8 drives the rotating rod 9 fixed at the output end to rotate. The rotating rod 9 rotates and drives the cams 10 fixed on both outer sides to rotate. When the two cams 10 rotate, they drive the bulk material plate 11 arranged on the upper part to move up and down reciprocally, break up the agglomerated particles, and make them cool evenly. Then, the cooled particles can be discharged through the discharge port 4. The speed of the motor 8 can be adjusted through the controller 6, so as to adjust the moving speed of the bulk material plate 11, realizing that when cooling the particles, it is convenient to break up the particles falling on the upper part of the bulk material plate 11. By breaking up the particles, the particles can be more evenly distributed on the bulk material plate 11, increasing the contact area between the particles and the cold air, promoting the rapid dissipation of heat, and thus improving the cooling efficiency. When scattering the particles, start the collecting fan 1805, collect the powder generated during scattering through the collecting hood 1808, then transport it through the conveying pipe 1807, and finally, transport the collected powder into the interior of the collecting box 1801 through the conveying pipe 1807. When the interior of the collecting box 1801 is full, take out the drawer 1802 from the interior of the collecting box 1801. Installing the filter screen 1804 inside the installation shell 1803 is convenient for filtering the collected powder, thereby prolonging the service life of the collecting fan 1805, realizing that when scattering the particles, it is convenient to collect the powder generated during scattering, and the powder can be reused or reprocessed, thereby improving the utilization rate of raw materials and reducing production costs.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
