[0025] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0026] A cooling device for the production of TPE granules includes a screw conveyor 1. The output port of the screw conveyor 1 is connected to a first cooling box assembly 2. A second cooling box assembly 3 is located at the bottom of the first cooling box assembly 2, and a conveyor belt assembly 4 is located at the bottom of the second cooling box assembly 3. When the screw conveyor 1 is started, the TPE granules to be cooled are fed into the conical shell 201 of the first cooling box assembly 2, where the granules are dispersed by contact with triangular rods 202. Simultaneously, the blower corresponding to the first cooling box is started, and external air, purified by a first filter assembly 208, is sent into the shell 201 to exchange heat with the granules for initial cooling. The initially cooled granules fall in a single curtain into the box 301 of the second cooling box assembly 3, where they roll on staggered corrugated guide plates 302 to prolong their residence time. Simultaneously, the blower corresponding to the second cooling box is started, and external air, purified by a second filter assembly 303, is sent into the box 301 to further exchange heat with the rolling granules, completing secondary cooling. During cooling, temperature sensors inside the conical shell 201 and the box 301 monitor the temperature in real time and provide feedback to the controller outside the second cooling box. The controller then automatically adjusts the blower speed and the conveying speed of the screw conveyor 1 to ensure sufficient cooling. The cooled particles fall into the conveyor belt assembly 4 at the bottom of the box 301 and are transported to the next process.
[0027] In this embodiment, please refer to Figure 1 and Figure 2 The first cooling box assembly 2 includes a conical shell 201. The interior of the conical shell 201 is provided with several triangular rods 202. A first filter plate 203 is provided on one inner side wall of the conical shell 201. Connecting posts 204 are provided at the four corners of the first filter plate 203, connecting the connecting posts 204 to a second filter plate 205. A third filter plate 206 is provided on the other side wall of the conical shell 201. A first exhaust fan 207 is symmetrically provided on the side of the third filter plate 206 away from the triangular rods 202. A first filter box assembly 208 is provided on one side of the first exhaust fan 207. TPE particles are fully dispersed in contact with the triangular rods 202 inside the conical shell 201. Simultaneously, the blower corresponding to the first cooling box assembly 2 is activated, purifying external air through the first filter box assembly 208 to remove impurities and harmful substances. The clean air is then delivered to the interior of the conical shell 201, where it exchanges heat with the TPE particles, carrying away the heat from the TPE particles and achieving initial cooling.
[0028] The triangular rods 202 are evenly distributed inside the conical shell 201, and the surface of the triangular rods 202 is provided with several protrusions to increase the contact area with TPE particles and improve the cooling effect. The triangular rods 202 are made of stainless steel and are welded to the second filter plate 205. The first filter plate 203 is fixed to the conical shell 201 by bolts, which facilitates disassembly and maintenance and improves the overall stability and maintainability of the device.
[0029] In this embodiment, please refer to Figure 1 and Figure 3 The second cooling box assembly 3 includes a box body 301. Inside the box body 301, several guide plates 302 are arranged alternately. A second exhaust fan 306 is symmetrically arranged on one side wall of the box body 301. A second filter box assembly 303 is arranged on the side of the second exhaust fan 306 away from the guide plates 302. The other side wall of the box body 301 has several slots 304. A fourth filter plate 305 is arranged inside the slots 304. Inside the box body 301, TPE particles roll on the alternately arranged wave-shaped guide plates 302, which prolongs the residence time of the particles in the box body 301. At the same time, the blower corresponding to the second cooling box assembly 3 is started, and the outside air is purified by the second filter box assembly 303 and then delivered to the inside of the box body 301. The clean air further exchanges heat with the TPE particles rolling on the guide plates 302, thereby achieving further cooling of the TPE particles.
[0030] The guide plate 302 is made of corrugated aluminum alloy plate, and avoids the use of Teflon coating for anti-sticking purposes. This increases the residence time and cooling path of TPE particles within the housing 301, thereby improving cooling efficiency.
[0031] The fourth filter plate 305 is fixed to the slot 304 by bolts. The second induced draft fan 306 has a screen on the side near the guide plate 302 to prevent TPE particles or impurities from entering the fan and protect its normal operation.
[0032] Both the first induced draft fan 207 and the second induced draft fan 306 are equipped with frequency converters to adjust the speed of the induced draft fans. Temperature sensors are installed inside the conical shell 201 and the box 301, respectively. A controller is installed outside the second cooling box assembly 3. The controller adjusts the speed of the first induced draft fan 207 and the second induced draft fan 306, as well as the conveying speed of the screw conveyor 1, according to the feedback signal from the temperature sensors. The speed of the induced draft fans can be adjusted according to actual needs to improve cooling efficiency and product quality stability.
[0033] Preferably, the first filter box assembly 208 and the second filter box assembly 303 each include a box shell, three sets of filter layers, and a sealing cover. The inside of the box shell forms a filter chamber, and the filter layers are detachably installed in the filter chamber. The sealing cover is fixed to the top of the box shell by bolts. The three sets of filter layers consist of a honeycomb primary filter layer, an activated carbon adsorption layer, and a HEPA high-efficiency filter layer, which are used to purify the air and remove impurities. They purify impurities and harmful substances in the air, ensure the cleanliness of the air inside the cooling device, and prevent TPE particles from being contaminated. At the same time, the detachable structure facilitates the replacement and maintenance of the filter layers, reducing maintenance costs.
[0034] The working process of this utility model is as follows: When using this cooling device for the production of TPE granular materials, firstly, the screw conveyor 1 is started to transport the TPE granules to be cooled into the conical shell 201 of the first cooling box assembly 2. The TPE granules are fully dispersed and in contact with the triangular rod 202 within the conical shell 201. Simultaneously, the blower corresponding to the first cooling box assembly 2 is started to purify external air through the first filter box assembly 208, removing impurities and harmful substances. The clean air is then delivered into the conical shell 201, where it exchanges heat with the TPE granules, carrying away their heat and achieving initial cooling. After initial cooling, the TPE granules fall into the box 301 of the second cooling box assembly 3 under gravity in a single curtain pattern. Inside the box 301, the TPE granules roll on the staggered wave-shaped guide plates 302, extending their residence time within the box 301. At the same time, the blower... The blower corresponding to the second cooling box assembly 3 purifies the outside air through the second filter box assembly 303 and then delivers it into the box body 301. The clean air further exchanges heat with the TPE particles rolling on the guide plate 302, achieving further cooling of the TPE particles. During the cooling process, temperature sensors installed in the conical shell 201 and the box body 301 monitor temperature changes in real time and feed the signals back to the controller outside the second cooling box assembly 3. The controller automatically adjusts the speed of the blower according to the feedback signal from the temperature sensor to control the airflow and cooling efficiency entering the cooling box. At the same time, the controller can also adjust the conveying speed of the screw conveyor 1 as needed to ensure that the TPE particles have sufficient residence time in the cooling box for thorough cooling. The cooled TPE particles finally fall onto the conveyor belt assembly 4 at the bottom of the second cooling box assembly 3 and are conveyed to the next process.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
