Description

Technical Field

[0001] The present invention relates to the technical field of plastic particle drying, and particularly to a drying device for plastic particle processing. Background Art

[0002] Plastic particles are the common name for plastic granules, which are granular raw materials formed after processing a polymer material. The size, shape, color, etc. of plastic particles vary depending on the type and use of the plastic. Common plastic particles include polyethylene (PE) particles, polypropylene (PP) particles, polyvinyl chloride (PVC) particles, polystyrene (PS) particles, etc. These plastic particles are the basic materials for manufacturing various plastic products. For example, plastic bags, plastic bottles, plastic pipes, plastic toys, etc. are all made by different processing techniques of plastic particles.

[0003] A drying device for plastic particle processing is a device used to remove moisture from plastic particles. It mainly consists of a drying box, a heating system, a ventilation system, a conveying system, etc. The drying box is the main part of the whole device, generally a closed box structure, and there are multiple layers of material placement racks or conveying tracks inside it for placing plastic particles. The heating system usually includes electric heating tubes, gas heaters or steam heaters, etc., and its function is to generate heat to raise the temperature inside the drying box, thereby accelerating the evaporation of moisture in the plastic particles. The ventilation system mainly includes a fan and ventilation ducts. The fan is used to make the air inside the drying box circulate, take away the evaporated moisture, ensure that the humidity inside the drying box remains at a low level, and enable the drying process to proceed continuously and effectively. The conveying system is used to convey plastic particles into the drying box and output the dried plastic particles from the drying box, and it can be in various forms such as a conveyor belt, a screw conveyor, etc. When the drying device is working, plastic particles are conveyed into the drying box. Under the combined action of the heating system and the ventilation system, the moisture is gradually removed. After the dried plastic particles reach the specified dryness, they leave the drying box through the conveying system, providing dried and qualified raw materials for subsequent plastic processing techniques.

[0004] However, when the existing drying devices for plastic particle processing process plastic particles, they generally adopt the method of pouring a large amount of plastic particles into the drying box all at once, and then use a heating device, a ventilation device and a stirring device to carry out stirring and drying operations on them. However, this traditional drying method has many drawbacks. Its drying efficiency is relatively low, and the drying effect is not satisfactory. When a large amount of plastic particles are poured into the drying box uniformly, the plastic particles at the bottom will accumulate in large quantities and it is difficult to fully and effectively contact with the hot air. Due to the obstruction of the hot air circulation path and the limited contact area, the particles at the bottom cannot fully absorb heat, and the moisture evaporation is slow, which seriously affects the overall drying efficiency;

[0005] In addition, during the drying process of plastic particles, since they contain a certain amount of moisture, this moisture will cause the plastic particles to adhere to each other, forming agglomeration or aggregation. The existing stirring device is often difficult to handle these aggregated plastic particles. Due to the limitations of the design and movement of the stirring blades, the aggregated particles cannot be fully dispersed, resulting in the internal particles being difficult to expose to the hot air environment, and an efficient drying effect cannot be achieved. The dried plastic particles may still have a lot of moisture, affecting the subsequent processing quality;

[0006] In addition, when the existing drying device is in operation, the moisture inside the plastic particles evaporates due to heat to form high-temperature and high-humidity gases. These gases diffuse in the drying room. Due to the lack of reasonable and effective exhaust design and airflow guidance mechanism, it is difficult to fully and evenly discharge them, so that moisture is easily accumulated in local areas and cannot be diffused to the exhaust port in time. This uneven moisture discharge will cause large differences in humidity at different locations in the drying room, which will cause serious damage to the uniformity of drying the plastic particles. Some areas may be over-dried, while other areas are under-dried, which brings great inconvenience and trouble to actual production applications and reduces the quality stability and consistency of the products.

[0007] Furthermore, most of the existing drying devices lack a complete dehumidification structure when dealing with the high-temperature moisture generated. Usually, the high-temperature moisture is directly discharged without effective treatment, which will not only cause the humidity in the working environment to rise sharply, forming a humid and stuffy working atmosphere, affecting the health and work comfort of the operators, but also easily be re-inhaled into the drying room by the ventilation system to participate in the hot air drying cycle. The re-inhaled moisture will reduce the drying capacity of the hot air, increase the drying time and energy consumption, and seriously interfere with the normal progress of the drying work. Although some drying devices use condensation dehumidification, this single dehumidification method is stretched when facing high-temperature moisture that is discharged quickly and has a large flow rate. The condensation efficiency is limited, and a large amount of moisture cannot be processed in time, resulting in a significant reduction in the dehumidification effect, which in turn causes great trouble to actual use.

[0017] Preferably, a rotating frame is rotatably connected inside the dividing frame. A silica gel drying circular plate is fixedly sleeved inside the rotating frame. Vanes are circumferentially distributed on the circumferential outer wall of the rotating frame. A semiconductor refrigerating sheet is also arranged on the circumferential outer wall of the fixed cylinder. A plurality of radiating fins are arranged on the outer wall of the semiconductor refrigerating sheet.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: In the process of processing and drying plastic particles, first, the closed door needs to be opened, and a large amount of plastic particles are poured into the drying chamber. Under the action of gravity, the plastic particles will naturally fall into the second fixed barrel. Then, the closed door is closed, and multiple drive motors are started. The drive motors can drive the toothed ring to rotate by using the drive gears. The rotation of the toothed ring will drive the sleeve cylinder to rotate synchronously. Multiple drying hollow rods arranged on the circumferential outer wall of the sleeve cylinder will also perform circular motion accordingly. At the same time, multiple connecting frames connected to the multiple drying hollow rods will also perform circular rotation. The circular rotation of the connecting frames will drive the mounting frame to rotate. The spiral feeding rod carried on the top of the mounting frame can also rotate synchronously during the rotation process, lifting and conveying the plastic particles accumulated at the bottom upward to the top of the distribution plate. At this time, the hot air blower is turned on, and the hot air generated by the hot air blower will be injected into the multiple drying hollow rods. The air outlet two on the outer wall of the drying hollow rod can evenly dry the plastic particles on the top of the distribution plate. In this way, the plastic particles accumulated at the bottom can also fully contact the hot air, effectively solving the problem that the particles at the bottom are difficult to be heated. In addition, part of the hot air will enter the inside of the sleeve cylinder through the multiple drying hollow rods, and perform secondary hot air blowing on the falling plastic particles. In addition, multiple stirring support rods carried on the connecting frames will also moderately stir the plastic particles during the circular motion. Through this multiple drying design, the drying efficiency of the plastic particles is greatly improved, and the situation that the drying effect is affected due to the difficulty of the particles to fully contact the hot air caused by particle accumulation is significantly reduced;

[0019] And during the rotation of the sleeve cylinder driven by multiple drive motors, multiple knocking components arranged on the top of the sleeve cylinder will move in a circular motion along with it. During the movement, the knocking components will continuously contact the inclined connecting seat at the bottom of the distribution plate. Since a return spring is provided inside the knocking component, when the knocking block moves to the bottom of the inclined connecting seat along with the sleeve rod, the return spring will be compressed to a certain extent. After passing through the inclined connecting seat, the return spring will quickly reset, and use the elastic force generated during this process to knock and vibrate the distribution plate. In this way, it can effectively cause the plastic particles gathered together to be shaken loose, thereby reducing the phenomenon of plastic particle aggregation or agglomeration, ensuring the uniformity and efficiency of the drying process. Moreover, during the circular rotation of the multiple drying hollow rods and the multiple connecting frames, they can also scrape and clean the inner walls of the first fixed barrel and the second fixed barrel, timely removing the plastic particles that may adhere to the inner walls, further reducing the possibility of plastic particles forming plates on the inner wall of the drying chamber, and ensuring the long-term stable operation of the drying equipment;

[0020] Furthermore, while the multiple connecting racks are rotating, a negative pressure environment is formed inside the connecting racks with the help of multiple externally connected air suction pumps, so as to extract and transfer the moisture inside the drying room. This active air suction method can ensure that the moisture in the drying room is evenly sucked out, effectively avoiding the problem of large humidity differences in different positions in the drying room due to uneven moisture discharge, thereby affecting the uniformity of drying. By accurately controlling the power and operating time of the air suction pump, it can be flexibly adjusted according to the actual humidity conditions in the drying room, so that the drying environment is always kept within an appropriate humidity range, providing a strong guarantee for high-quality drying operations;

[0021] After the moisture inside the drying chamber is sucked out, it will be transferred to the inside of the dehumidification component. First, the moisture will be initially adsorbed and dehumidified by the silica gel drying disc. After the initial dehumidification is completed, the gas will be transferred to the biased position on the top of the fixed barrel by wind traction, thereby exerting a force on the blades on the outer wall of the rotating frame. Driven by the wind, the blades cause the rotating frame carrying the silica gel drying disc to start rotating. In this way, the adsorption saturated area on the silica gel drying disc will pass through the electric heating network in turn as it rotates. At this time, under the coordinated action of multiple external fans, the high-temperature heat source on the electric heating network will be blown to the adsorption saturated area, and the moisture adsorbed in this area will be desorbed, thereby realizing the recycling and reuse of the silica gel drying disc and achieving the purpose of cyclic dehumidification. In the process of rotation of multiple blades, the blades will pass through the semiconductor system one by one. The cold plate cools the blades with a certain temperature by means of the cooling effect of the semiconductor refrigeration plate. The cooled blades can further condense the gas pulled over to drive the rotating frame to rotate, so that the moisture in the gas is further precipitated. The condensed water and the desorbed water will fall into the fixed base box through the through-port one, through-port two and through-port three, and can be discharged through the water valve. Through this composite moisture treatment method, the moisture in the wet gas can be extracted and separated more comprehensively and efficiently, greatly improving the dehumidification effect. At the same time, this composite dehumidification design that uses the initially dehumidified gas to drive the recycling of the silica gel drying disc can also form a synergistic gain effect, effectively reducing the trouble of frequent replacement of the silica gel drying disc due to adsorption saturation, and reducing the maintenance cost and operating energy consumption of the equipment.

[0054] Working principle of the present invention: In the process of processing and drying plastic particles, first, the closing door 236 needs to be opened, and a large amount of plastic particles are poured into the drying chamber. Under the action of gravity, the plastic particles will naturally fall into the second fixed barrel 230. Then, the closing door 236 is closed, and multiple driving motors 271 are started. The driving motors 271 can drive the toothed ring 220 to start rotating by using the driving gears 272. The rotation of the toothed ring 220 will drive the socket cylinder 250 to rotate synchronously. Multiple drying hollow rods 252 arranged on the circumferential outer wall of the socket cylinder 250 will also perform circular motion accordingly. At the same time, multiple connecting frames 260 connected to the multiple drying hollow rods 252 will also perform circular rotation.

The spiral feeding rod 264 carried on the top of the mounting frame 263 can also rotate synchronously during the rotation process, lifting the plastic particles piled up at the bottom upward and conveying them to the top of the distributing plate 242. At this time, the hot air blower 120 is turned on, and the hot air generated by the hot air blower 120 will be injected into the multiple drying hollow rods 252. The air outlets II on the outer walls of the drying hollow rods 252 can evenly dry the plastic particles on the top of the distributing plate 242. In this way, the plastic particles piled up at the bottom can also fully contact the hot air, effectively solving the problem that the particles at the bottom are difficult to be heated. In addition, part of the hot air will enter the socket cylinder 250 through the multiple drying hollow rods 252, and blow the falling plastic particles with hot air for the second time. Moreover, multiple stirring support rods 261 carried on the connecting frames 260 will also moderately stir the plastic particles during the circular motion. Through this multi-mode drying design, the drying efficiency of the plastic particles is greatly improved, and the situation that the drying effect is affected due to the difficulty of the particles to fully contact the hot air caused by particle accumulation is significantly reduced. And during the rotation of the socket cylinder 250 driven by the multiple driving motors 271, multiple knocking components arranged on the top of the socket cylinder 250 will move in a circular motion along with it. During the movement, the knocking components will continuously contact the inclined connecting seat 243 at the bottom of the distributing plate 242. Since a reset spring 255 is provided inside the knocking component, when the knocking block 257 moves to the bottom of the inclined connecting seat 243 along with the socket rod 256, the reset spring 255 will be compressed to a certain extent. After passing the inclined connecting seat 243, the reset spring 255 will quickly reset, and knock and vibrate the distributing plate 242 by means of the elastic force generated during this process. In this way, it can effectively cause the plastic particles gathered together to be shaken loose, thereby reducing the phenomenon of plastic particle aggregation or caking, ensuring the uniformity and efficiency of the drying process. Moreover, during the circular rotation of the multiple drying hollow rods and the multiple connecting frames, they can also scrape and clean the inner walls of the first fixed barrel 200 and the second fixed barrel 230, timely removing the plastic particles that may adhere to the inner walls, further reducing the possibility of plastic particles caking on the inner wall of the drying chamber, and ensuring the long-term stable operation of the drying equipment. While the multiple connecting frames 260 are rotating,With the help of multiple externally connected suction pumps 273, a negative pressure environment is formed inside the connecting frame 260, so as to extract and transfer the moisture inside the drying chamber. This active air extraction method can ensure that the moisture in the drying chamber is evenly sucked out, effectively avoiding the problem that the humidity difference at different positions in the drying chamber is large due to uneven moisture discharge, which in turn affects the drying uniformity. By precisely controlling the power and running time of the suction pump, it can be flexibly adjusted according to the actual humidity situation in the drying chamber, so that the drying environment is always maintained within an appropriate humidity range, providing a strong guarantee for high-quality drying operations. When the moisture inside the drying chamber is completely sucked out, it will be transferred to the dehumidification component. First, the moisture will be preliminarily adsorbed and dehumidified through the silica gel drying round plate 371. After the preliminary dehumidification is completed, the gas will be transported to the deflected position at the top of the fixed barrel 330 by wind traction, so as to apply a force to the blades 372 on the circumferential outer wall of the rotating frame 370, causing the blades to drive the rotating frame carrying the silica gel drying round plate 371 to rotate under the drive of the wind. In this way, the saturated adsorption area on the silica gel drying round plate 371 will sequentially pass through the electric heating grid 361 as it rotates. At this time, under the coordinated action of multiple external fans, the high-temperature heat source on the electric heating grid 361 will be blown towards the saturated adsorption area to desorb the moisture adsorbed in this area, thereby realizing the cyclic regeneration and utilization of the silica gel drying round plate 371 and achieving the purpose of cyclic dehumidification. And during the rotation of the multiple blades 372, the blades 372 will pass through the semiconductor refrigeration sheet 332 one by one. With the refrigeration effect of the semiconductor refrigeration sheet 332, the blades 372 with a certain temperature will be cooled. The cooled blades 372 can further condense the gas that is drawn over to drive the rotation of the rotating frame 370 again, so that more moisture in the gas is precipitated. The condensed water and the desorbed water will fall into the fixed base box 300 through the through-hole one 320, the through-hole two 335 and the through-hole three 337, and can be discharged through the water valve 310. Through this compound moisture treatment method, the moisture in the moisture can be extracted and separated more comprehensively and efficiently, greatly improving the dehumidification effect. At the same time, this compound dehumidification design that uses the preliminarily dehumidified gas to drive the cyclic regeneration of the silica gel drying round plate 371 can also form a synergistic gain effect, effectively reducing the trouble of frequent replacement due to the saturated adsorption of the silica gel drying round plate, and reducing the equipment maintenance cost and operation energy consumption.
