Description

Technical Field

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

[0002] Plastic particles are the common name for plastic particles. They are granular raw materials formed by processing high molecular polymer materials. The size, shape, color, etc. of plastic particles vary depending on the type and purpose 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 making various plastic products. For example, plastic bags, plastic bottles, plastic pipes, plastic toys, etc. are all made by processing plastic particles in different ways.

[0003] The drying device for plastic particle processing is a device used to remove moisture from plastic particles. It is mainly composed of a drying box, a heating system, a ventilation system, a conveying system and other parts. The drying box is the main part of the whole device, which is generally a closed box structure, and is equipped with a multi-layer material placement rack or a conveying track inside for placing plastic particles. The heating system usually includes an electric heating tube, a gas heater or a steam heater, etc., which generates heat to increase the temperature in the drying box, thereby accelerating the evaporation of moisture in the plastic particles. The ventilation system mainly includes a fan and a ventilation duct. The fan is used to circulate the air in the drying box, take away the evaporated moisture, ensure that the humidity in the drying box is kept at a low level, and enable the drying process to be carried out continuously and effectively. The conveying system is used to transport the plastic particles into the drying box and output the dried plastic particles from the drying box. It can be in the form of a conveyor belt, a screw conveyor and other forms. When the drying device is working, the plastic particles are transported into the drying box. Under the joint 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 dry and qualified raw materials for the subsequent plastic processing technology.

[0004] However, when processing plastic particles, the existing drying device for processing plastic particles generally adopts a method of pouring a large number of plastic particles into the drying box at one time, and then stirring and drying them with the help of a heating device, a ventilation device and a stirring device. However, this traditional drying method has many disadvantages, and its drying efficiency is relatively low, and the drying effect is not satisfactory. When a large number of plastic particles are poured into the drying box at the same time, 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 bottom particles cannot fully absorb heat, and the water evaporates slowly, 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.

[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 to pour a large amount of plastic particles into the drying chamber. Under the action of gravity, the plastic particles will naturally fall into the fixed barrel 2, and then the closed door is closed and multiple driving motors are started. The driving motor can use the driving gear to drive the toothed ring to start rotating. The rotation of the toothed ring will drive the sleeve barrel to rotate synchronously, and the multiple drying hollow rods arranged on the circumferential outer wall of the sleeve barrel will also perform circular motion accordingly. At the same time, the multiple connecting frames connected to the multiple drying hollow rods also perform circular rotation, and the circumferential rotation of the connecting frames will link the mounting frame to rotate, and the spiral feeding rod carried on the top of the mounting frame can also rotate synchronously during the rotation process to move the plastic particles accumulated at the bottom to the The plastic particles on the top of the dividing plate are evenly dried by the hot air outlet on the outer wall of the drying hollow rods. In this way, the plastic particles accumulated at the bottom can also be fully exposed to the hot air, which effectively solves the problem that the bottom particles are difficult to heat. In addition, part of the hot air will enter the sleeve through the multiple drying hollow rods to blow the falling plastic particles with secondary hot air. In addition, the multiple stirring rods carried on the connecting frame will also stir the plastic particles appropriately during the circular motion. This multiple drying design greatly improves the drying efficiency of the plastic particles and significantly reduces the situation where the drying effect is affected by the difficulty in fully contacting the hot air due to the accumulation of particles.

[0019] When the plurality of driving motors drive the sleeve barrel to rotate, the plurality of knocking assemblies arranged on the top of the sleeve barrel will move in a circle therewith. During the movement, the knocking assemblies will continuously contact with the inclined connection seat at the bottom of the dividing plate. Since a reset spring is arranged inside the knocking assembly, when the knocking block moves to the bottom of the inclined connection seat along with the sleeve rod, the reset spring will be compressed to a certain extent. After passing through the inclined connection seat, the reset spring will quickly reset, and the dividing plate will be knocked and vibrated by means of the elastic force generated in this process. In this way, the gathered plastic particles can be effectively shaken apart, thereby reducing the aggregation or agglomeration of plastic particles, ensuring the uniformity and efficiency of the drying process. Moreover, during the circular rotation of the plurality of drying hollow rods and the plurality of connecting frames, they can also scrape and clean the inner walls of the fixed barrel one and the fixed barrel two, timely remove the plastic particles that may be attached to the inner walls, further reduce the possibility of the plastic particles agglomerating on the inner wall of the drying chamber, and ensure 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, the closed door 236 needs to be opened first, 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 fixed barrel 230, and then the closed door 236 is closed, and the plurality of driving motors 271 are started. The driving motor 271 can use the driving gear 272 to drive the toothed ring 220 to start rotating. The rotation of the toothed ring 220 will drive the sleeve tube 250 to rotate synchronously, and the plurality of drying hollow rods 252 arranged on the circumferential outer wall of the sleeve tube 250 will also perform circular motion. At the same time, the plurality of connecting frames 260 connected to the plurality of drying hollow rods 252 also perform circular rotation, and the circumferential rotation of the connecting frame 260 will link the mounting frame The spiral feed rod 264 carried on the top of the mounting frame 263 can also rotate synchronously during the rotation process, and the plastic particles accumulated at the bottom are lifted and transported to the top of the dividing 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 exhaust port 2 on the outer wall of the drying hollow rod 252 can evenly dry the plastic particles on the top of the dividing plate 242. In this way, the plastic particles accumulated at the bottom can also be fully exposed to the hot air, which effectively solves the problem that the bottom particles are difficult to heat, and part of the hot air will also enter the sleeve 250 through the multiple drying hollow rods 252, and the falling plastic particles are blown with secondary hot air. In addition, the connecting frame 2 The multiple stirring support rods 261 carried on 60 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 in which the drying effect is affected by the accumulation of particles and the difficulty in fully contacting the hot air is significantly reduced. In addition, during the period when the multiple driving motors 271 drive the sleeve tube 250 to rotate, the multiple knocking components set on the top of the sleeve tube 250 will move in a circular motion with it. During the movement, the knocking components will continue to contact with the inclined connecting seat 243 at the bottom of the dividing plate 242. Since a return 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 sleeve rod 256, the return spring 255 will be The plastic particles 242 are compressed to a certain extent, and after passing through the inclined connecting seat 243, the reset spring 255 will quickly reset, and the elastic force generated in this process will knock and vibrate the dividing plate 242. In this way, the plastic particles gathered together can be effectively shaken apart, thereby reducing the aggregation or agglomeration of plastic particles, ensuring the uniformity and efficiency of the drying process, and in the process of the circular rotation of multiple drying hollow rods and multiple connecting racks, they can also scrape and clean the inner walls of the fixed barrel 1 200 and the fixed barrel 230, and promptly remove the plastic particles that may be attached to the inner walls, further reducing the possibility of plastic particles agglomerating on the inner wall of the drying chamber, ensuring the long-term stable operation of the drying equipment, while the multiple connecting racks 260 rotate.With the help of multiple externally connected air 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 room. This active air suction method can ensure that the moisture in the drying room is evenly sucked out, and effectively avoid the problem of large humidity differences at different positions in the drying room due to uneven moisture discharge, which in turn affects the drying uniformity. 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. 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 371. After the initial dehumidification is completed, the gas is transferred to the deflected position on the top of the fixed cylinder 330 by wind traction, so as to exert a force on the blades 372 on the outer wall of the circumference of the rotating frame 370, so that the blades drive the rotating frame carrying the silica gel drying disc 371 to start rotating under the drive of the wind. In this way, the adsorption saturated area on the silica gel drying disc 371 will pass through the electric heating network 361 in turn as it rotates. At this time, under the coordinated action of multiple external fans, the electric heating network 3 The high-temperature heat source on 61 will be blown to the adsorption saturation area, and the water adsorbed in this area will be desorbed, so as to realize the recycling and reuse of the silica gel drying disc 371 and achieve the purpose of cyclic dehumidification. In the process of the rotation of multiple blades 372, the blades 372 will pass through the semiconductor refrigeration sheet 332 one by one, and the blades 372 with a certain temperature will be cooled by the cooling effect of the semiconductor refrigeration sheet 332. The cooled blades 372 can further condense the gas pulled over to drive the rotating frame 370 to rotate, so that the water in the gas is further precipitated, and the condensed water and the desorbed water will be condensed again. The water after dehumidification will fall into the fixed base box 300 through the through-port 1 320, the through-port 2 335 and the through-port 3 337, and can be discharged through the water valve 310. Through this composite 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 composite dehumidification design that uses the initial dehumidified gas to drive the silica gel drying disc 371 to regenerate 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.
