Description

Technical Field

[0001] This utility model relates to the field of plastic granule drying technology, and in particular to a novel plastic granule drying device. Background Technology

[0002] Plastic granules refer to granular plastics, which are generally classified into more than 200 types and further subdivided into thousands of types. Common plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane. Engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, and polycarbonate. Specialty plastics include thermosetting plastics and functional polymer plastics, such as artificial kidneys.

[0003] Plastic granules need to be dried during processing. Existing plastic granulation equipment dries the plastic granules by blowing hot air. The plastic granules are mostly piled up together. The plastic granules inside are difficult to heat up, while the plastic granules on the outside are overheated. The equipment cannot tumble and dry the plastic granules, resulting in uneven heating and reduced product quality.

[0004] Therefore, it is necessary to provide a new type of plastic granule drying equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a novel plastic granule drying device, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel plastic granule drying device, including a drying chamber. A conversion box is fixed to the bottom surface of the drying chamber, and a rotary motor is installed on the bottom surface of the conversion box. A main heat pipe is installed through the output end of the rotary motor, passing through the conversion box and the bottom surface of the drying chamber. The main heat pipe extends into the interior of the drying chamber. A secondary heat pipe is installed through the surface of the main heat pipe, and an air outlet is opened on the surface of the secondary heat pipe. An air inlet is opened on the peripheral side of the main heat pipe inside the conversion box. A gas delivery pipe is installed through the surface of the conversion box, and the other end of the gas delivery pipe is connected to a hot air source. In this structural design, the drying chamber serves as the main spatial carrier for drying plastic granules, and the conversion box acts as a transfer point connecting the drying chamber and the rotary motor, providing a transfer for hot air transmission. The rotary motor drives the main heat pipe to rotate through its output end, enabling the main heat pipe to perform the dual functions of transmitting hot air and stirring plastic granules. The secondary heat pipe installed through the surface of the main heat pipe, in conjunction with the air outlet, can evenly deliver the hot air introduced from the gas delivery pipe and the air inlet to various positions inside the drying chamber. During the rotation of the main heat pipe and the secondary heat pipe, on the one hand, the accumulated plastic granules are tumbled and stirred, breaking up the granules and allowing the internal plastic granules to fully contact the hot air. This avoids the problem of the external plastic granules being overheated while the internal plastic granules are difficult to heat, thus achieving uniform drying of the plastic granules. On the other hand, the hot air acts directly on the plastic granules through the air outlet on the surface of the secondary heat pipe, accelerating the drying speed and significantly improving the drying efficiency and the quality of the finished plastic granules.

[0007] Preferably, a filter plate is installed inside the drying chamber. The filter plate has perforated holes on its surface and is installed inside the drying chamber; the perforations on its surface have a screening function. During the stirring and drying process of the plastic granules by the main and secondary heat pipes, the plastic granules may rub against other components or themselves during tumbling, potentially generating debris. The filter plate can intercept these debris, allowing only plastic granules of the correct size to fall through the filter holes. After drying, the qualified plastic granules can be collected through the lower channel, while the debris remains above the filter plate and is subsequently cleaned through the drain port. This design effectively prevents debris from mixing into the finished plastic granules, improving the purity of the plastic granules and thus enhancing the quality of the plastic granules used in later stages, reducing manufacturing defects in plastic products caused by the presence of debris.

[0008] Preferably, multiple secondary heat pipes are installed, and these secondary heat pipes are equidistantly mounted on the surface of the primary heat pipe. A breathable dustproof membrane is installed on the outer surface of the air outlet. The multiple secondary heat pipes equidistantly mounted on the surface of the primary heat pipe can cover a larger area during rotation, ensuring comprehensive and thorough hot air delivery and agitation of the plastic particles within the drying chamber. The evenly distributed secondary heat pipes ensure that the plastic particles receive the same degree of drying treatment in all areas of the drying chamber, further guaranteeing the uniformity of drying. The breathable dustproof membrane installed on the outer surface of the air outlet not only ensures smooth hot air discharge but also prevents plastic particles from entering the secondary heat pipes and causing blockages, maintaining the unobstructed hot air transmission channel and ensuring the continuous and stable operation of the drying process, avoiding the impact of pipe blockage on drying efficiency and effect.

[0009] Preferably, a sealed bearing is installed at the contact point between the main heat pipe and the conversion box and the drying box. The sealed bearing is installed at the contact point between the main heat pipe and the conversion box and the drying box. Its main function is to provide a good sealing effect while ensuring that the main heat pipe can rotate flexibly.

[0010] Preferably, the outer surface of the drying chamber is equipped with a discharge port and a drain port, both with covers. A sealing cover is installed at the top of the drying chamber, with a feed inlet on the top surface of the cover. An exhaust pipe is installed on one side of the feed inlet. The discharge port on the outside of the drying chamber is used to discharge the dried, qualified plastic granules, while the drain port is used to clean impurities and debris trapped by the filter plate. The covers on the discharge and drain ports maintain the airtightness of the chamber during operation, preventing heat leakage and the entry of external debris. The sealing cover at the top of the drying chamber, in conjunction with the feed inlet, facilitates the operator in placing the plastic granules to be dried into the drying chamber while ensuring the internal sealing of the chamber. The exhaust pipe is used to expel moisture and excess heat generated during the drying process, maintaining air circulation and a stable drying environment within the chamber, preventing moisture accumulation from affecting the drying effect of the plastic granules, and ensuring the smooth progress and quality of the drying process.

[0011] Preferably, the bottom surface of the drying chamber is fixed with support legs, and multiple support legs are installed, with the multiple support legs evenly distributed at intervals on the bottom surface of the drying chamber. These equally spaced support legs provide a stable support structure for the drying chamber. During equipment operation, the rotary motor drives the main and secondary heat pipes to rotate, generating certain vibrations and forces. The stable support legs effectively disperse these forces, preventing the drying chamber from shaking or tilting, ensuring the stability and safety of the equipment operation.

[0012] Preferably, a controller is installed on the outer surface of the drying chamber. This controller serves as the control center of the equipment, allowing operators to adjust and control parameters such as the rotational speed of the rotary motor, the temperature of the hot air source, and the hot air flow rate. Based on the drying requirements of different types and humidity levels of plastic granules, the operating parameters can be flexibly adjusted to achieve personalized and precise drying. Simultaneously, the controller can also monitor the equipment's operating status in real time and diagnose faults. When abnormalities occur, it promptly issues alarms and takes corresponding protective measures to ensure the normal operation of the equipment and the safety of the operators, thereby improving the equipment's intelligence and ease of use.

[0013] Compared with related technologies, the novel plastic granule drying equipment provided by this utility model has the following beneficial effects:

[0014] Compared to existing technologies, this drying oven features a fixed conversion box at its bottom, with a rotary motor mounted thereon. The motor's output drives the primary heat pipe to rotate. An outlet is located on the secondary heat pipe on the surface of the primary heat pipe. Hot air enters the primary and secondary heat pipes through the air supply pipe and inlet, and exits through the outlet. During the rotation of the primary heat pipe, the secondary heat pipe continuously changes position, enabling comprehensive hot air delivery to the plastic granules accumulated within the drying oven. This avoids the problem of internal heat loss and external overheating caused by granule accumulation, achieving tumbling drying of the plastic granules. This ensures uniform heating and significantly improves drying efficiency and finished product quality.

[0015] Compared to existing technologies, the horizontally mounted filter plate inside the drying oven has a surface densely covered with filter holes. When the rotary motor drives the main and auxiliary heat pipes to rotate and stir the plastic granules, it not only ensures that the hot air contacts the plastic granules evenly, but also utilizes the particle movement generated by the stirring to promote full contact between the plastic granules and the filter plate. During this process, debris and small impurities in the plastic granules, being smaller than the filter holes, will fall through the holes under the influence of gravity and particle movement, while intact and qualified plastic granules are intercepted above the filter plate. This design effectively removes debris and impurities from the plastic granules, preventing them from affecting product performance in subsequent processing and use, and greatly improving the quality of the plastic granules.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] Please refer to the following: Figure 1-4 A novel plastic granule drying device includes a drying chamber 1. The drying chamber 1 has a conversion chamber 6 fixed to its bottom surface. A rotary motor 13 is mounted on the bottom surface of the conversion chamber 6. A main heat pipe 11 is installed at the output end of the rotary motor 13, passing through the conversion chamber 6 and the bottom surface of the drying chamber 1. The main heat pipe 11 extends into the interior of the drying chamber 1. A secondary heat pipe 10 is installed through the surface of the main heat pipe 11. An air outlet 17 is provided on the surface of the secondary heat pipe 10. An air inlet 16 is provided on the peripheral side of the main heat pipe 11 inside the conversion chamber 6. A gas delivery pipe 15 is installed through the surface of the conversion chamber 6, and the other end of the gas delivery pipe 15 is connected to a heat source.

[0026] During equipment assembly, the conversion box 6 is first securely fixed to the bottom surface of the drying chamber 1 by welding or bolting, forming a stable upper and lower layer structure. The conversion box 6 not only serves as a bridge connecting the drying chamber 1 and the rotary motor 13, but also provides a transfer space for heat transfer. Next, the rotary motor 13 is firmly fixed in the pre-reserved mounting groove on the bottom surface of the conversion box 6 with bolts to ensure the stability of the motor operation. The output end of the rotary motor 13 is connected to the main heat pipe 11 through a coupling. This connection method ensures stable power transmission and facilitates later maintenance and disassembly. The main heat pipe 11 passes through the pre-drilled through holes at the bottom of the conversion box 6 and the drying chamber 1, and sealed bearings are installed at the through holes to ensure the airtightness of the chamber while enabling the main heat pipe 11 to rotate.

[0027] After the main heat pipe 11 extends into the drying chamber 1, multiple secondary heat pipes 10 are installed on its surface at equal intervals via welding or flange connection. The through connection between the secondary heat pipes 10 and the main heat pipe 11 allows hot air to flow smoothly from the main heat pipe 11 into the secondary heat pipes 10. The evenly spaced air outlets 17 on the surface of the secondary heat pipes 10 can accurately deliver hot air to various areas within the drying chamber 1. Inside the conversion chamber 6, air inlets 16 are provided on the circumferential side of the main heat pipe 11. The air inlets 16 are connected to the air supply pipes 15 installed through the surface of the conversion chamber 6. The other end of the air supply pipes 15 is connected to the hot air source via quick connectors or flanges, facilitating the access and replacement of the hot air source.

[0028] During operation, the rotary motor 13 starts, driving the main heat pipe 11 to rotate at high speed via its output end. The main heat pipe 11 then drives the secondary heat pipe 10 to rotate synchronously. During rotation, the secondary heat pipe 10 continuously tumbles and stirs the accumulated plastic granules, breaking up their aggregated state. Simultaneously, hot air generated by the heat source enters the main heat pipe 11 through the air supply pipe 15 and the air inlet 16, then flows to the secondary heat pipe 10, and finally is evenly blown out from the air outlet 17. This dual action of mechanical stirring and hot air transfer allows the internal plastic granules to fully contact the hot air, avoiding the problem of excessive heating of the external plastic granules and insufficient heating of the internal plastic granules. This achieves uniform drying of the plastic granules, significantly improving drying efficiency and the quality of the finished plastic granule product.

[0029] The working principle of the novel plastic granule drying equipment provided by this utility model is as follows:

[0030] First, the plastic granules to be dried are poured into the drying chamber 1 through the feed inlet 2 at the top of the sealing cover 4. Next, the controller 5 installed on the outer surface of the drying chamber 1 is started. The controller 5 controls the rotary motor 13 to start working. The output end of the rotary motor 13 rotates, driving the main heat pipe 11 that runs through the bottom of the conversion box 6 and the drying chamber 1 to rotate. The main heat pipe 11 is rotatably connected to the conversion box 6 and the drying chamber 1 through a sealed bearing, ensuring the sealing during the rotation process and preventing hot air leakage.

[0031] Simultaneously, hot air generated by the heat source is transported to the conversion box 6 through the air supply pipe 15. Since the main heat pipe 11 has an air inlet 16 located inside the conversion box 6, the hot air enters the main heat pipe 11 through the air inlet 16. Multiple secondary heat pipes 10, which are installed through the surface of the main heat pipe 11, rotate along with the main heat pipe 11 as it rotates. During rotation, the air outlets 17 on the surface of the secondary heat pipes 10 evenly blow hot air onto the plastic particles in various locations within the drying chamber 1, drying the plastic particles. Multiple secondary heat pipes 10 are installed at equal intervals on the surface of the main heat pipe 11, and a breathable dustproof membrane 14 is installed on the outside of the air outlets 17. The breathable dustproof membrane 14 prevents plastic particles from entering the secondary heat pipes 10 and causing blockage, ensuring smooth exhaust of hot air and further ensuring the uniformity of drying the plastic particles.

[0032] During the drying process of plastic granules, the filter plate 12 located inside the drying chamber 1 plays a crucial role. When the main heat pipe 11 drives the secondary heat pipe 10 to stir the plastic granules, the movement of the granules causes debris and impurities to fall through the filter holes. After drying, the cover of the discharge port 9 is opened, and qualified plastic granules are discharged and collected through the discharge port 9; the cover of the drain port 8 is opened to clean and discharge the debris and impurities collected below the filter plate 12. The exhaust pipe 3 at the top of the drying chamber 1 is used to discharge the moisture and excess heat generated during the drying process, ensuring a stable drying environment inside the drying chamber 1.

[0033] Example 3, see Figure 1-4 The drying oven 1 is equipped with a filter plate 12, and the surface of the filter plate 12 is provided with filter holes.

[0034] The filter plate 12 is horizontally installed inside the drying chamber 1 and is fixed by pre-welded support bosses or slots on the inner wall of the drying chamber 1, ensuring that the filter plate 12 remains stable during equipment operation and will not shift due to vibration. The filter pores evenly distributed on the surface of the filter plate 12 are precisely designed according to the qualified particle size of the plastic particles, allowing only qualified plastic particles to pass through while intercepting debris and fine impurities generated during the stirring and drying process.

[0035] During equipment operation, the main heat pipe 11 and the secondary heat pipe 10 stir and dry the plastic granules, ensuring full contact between the granules and the filter plate 12 during the tumbling motion. Qualified plastic granules, due to their suitable particle size, can smoothly pass through the filter holes and fall to the bottom of the drying chamber 1; while debris and impurities are intercepted above the filter plate 12. After drying, opening the drain port 8 cover on the outside of the drying chamber 1 allows the impurities intercepted above the filter plate 12 to be cleaned and discharged; opening the discharge port 9 cover allows the qualified dried plastic granules to be discharged and collected through the discharge port 9. This design effectively prevents debris from mixing into the finished plastic granules, greatly improving the purity of the plastic granules, thereby enhancing the quality of subsequent use of the plastic granules and reducing production defects in plastic products caused by the presence of debris.

[0036] Example 3, see Figure 1-4 Multiple secondary heat pipes 10 are installed, and the multiple secondary heat pipes 10 are installed at equal intervals on the surface of the primary heat pipe 11. A breathable and dustproof membrane 14 is installed on the outer surface of the air outlet 17.

[0037] Multiple secondary heat pipes 10 are fixed to the surface of the primary heat pipe 11 at equal intervals by welding or threading. This uniformly distributed installation method allows the secondary heat pipes 10 to cover a larger area within the drying chamber 1 during rotation, ensuring comprehensive and thorough hot air delivery and agitation of the plastic particles. After installation, a breathable dustproof membrane 14 is installed on the outside of the air outlet 17 on the surface of each secondary heat pipe 10 by adhesive bonding or clip fixing. The breathable dustproof membrane 14 has good air permeability, ensuring smooth hot air discharge, while its fine structure effectively prevents plastic particles from entering the interior of the secondary heat pipes 10, avoiding pipe blockage and maintaining unobstructed hot air transmission channels.

[0038] During equipment operation, multiple auxiliary heat pipes 10 rotate in tandem, evenly blowing hot air onto the plastic granules in various locations within the drying chamber 1. This ensures that the plastic granules receive the same level of drying treatment in all areas of the drying chamber 1, further guaranteeing the uniformity of drying. Simultaneously, the breathable and dustproof membrane 14 continuously functions, preventing granules from entering the auxiliary heat pipes 10 even when the plastic granules are violently tumbling, ensuring the continuous and stable drying process and avoiding any impact on drying efficiency and effectiveness due to pipe blockage.

[0039] Example 3, see Figure 1-4 A sealed bearing is installed at the contact point between the main heat pipe 11 and the conversion box 6 and the drying box 1.

[0040] When installing the main heat pipe 11, a sealed bearing is first embedded in the pre-drilled through hole at the bottom of the conversion box 6 and the drying box 1. The outer ring of the sealed bearing is tightly connected to the inner wall of the through hole by interference fit or bolt fixing; the inner ring is tightly fitted with the main heat pipe 11, ensuring that the main heat pipe 11 can rotate flexibly within the sealed bearing. This installation method not only ensures the smooth rotation of the main heat pipe 11, but also provides a good sealing effect for the equipment.

[0041] During equipment operation, hot air enters the main heat pipe 11 and the secondary heat pipe 10 through the air supply pipe 15 and the air inlet 16. If the main heat pipe 11 is not properly sealed at the contact point with the chamber, a large amount of hot air will leak to the outside of the equipment, causing not only serious energy waste but also reducing the pressure and temperature of the hot air inside the drying chamber 1, affecting the drying effect. The presence of the sealed bearing forms a reliable sealing barrier, ensuring that the hot air is transported within the closed piping system, maintaining the stability of the drying environment inside the drying chamber 1 and the efficient utilization of the hot air. Even when the equipment is running for a long time and the main heat pipe 11 is continuously rotating, the sealed bearing can effectively prevent hot air leakage, ensuring that the drying process proceeds stably as expected.

[0042] Example 3, see Figure 1-4 The outer surface of the drying box 1 is equipped with a discharge port 9 and a drain port 8. The discharge port 9 and the drain port 8 are equipped with cover plates. A sealing cover 4 is installed at the top of the drying box 1. A feed port 2 is opened on the top surface of the sealing cover 4. An exhaust pipe 3 is installed on one side of the feed port 2.

[0043] On the outer surface of the drying chamber 1, a discharge port 9 and a drain port 8 are cut and welded according to design requirements. The dimensions of the discharge port 9 and drain port 8 are designed based on the discharge requirements of plastic particles and the need for impurity removal, ensuring that plastic particles and impurities can be discharged smoothly. Suitable covers are installed on the discharge port 9 and drain port 8, and the covers are connected to the drying chamber 1 via hinges or latches for easy opening and closing. Rubber sealing rings are installed at the contact points between the covers and the chamber body to ensure airtightness during equipment operation and prevent heat leakage and the entry of external debris.

[0044] A sealing cover 4 is bolted to the top of the drying chamber 1. A rubber sealing ring is also installed between the sealing cover 4 and the drying chamber 1 to ensure the airtightness of the interior of the drying chamber 1. The feed inlet 2 at the top of the sealing cover 4 is used by the operator to put the plastic granules to be dried into the drying chamber 1. An exhaust pipe 3 is installed on one side of the feed inlet 2, with one end connected to the interior of the drying chamber 1 and the other end connected to the external environment. A one-way valve or filter is installed inside the exhaust pipe 3 to prevent external debris from entering the drying chamber 1, while ensuring that moisture and excess heat generated during the drying process can be smoothly discharged.

[0045] During equipment operation, the sealing cover 4 and the cover plate maintain a dry environment inside the drying chamber 1; the exhaust pipe 3 promptly discharges moisture and excess heat, ensuring air circulation within the drying chamber 1 and preventing moisture accumulation from affecting the drying effect of the plastic granules. After drying, the discharge port 9 cover is opened, and qualified plastic granules are discharged and collected through the discharge port 9; the drain port 8 cover is opened to clean and discharge impurities and debris intercepted by the filter plate 12, ensuring the cleanliness of the equipment and its subsequent normal operation.

[0046] Example 3, see Figure 1-4 The bottom surface of the drying box 1 is fixed with a support leg 7, and multiple support legs 7 are installed, and the multiple support legs 7 are distributed at equal distances on the bottom surface of the drying box 1.

[0047] Multiple support legs 7 are pre-welded or bolted to the bottom surface of the drying chamber 1. The support legs 7 are connected to the mounting bases by bolts. During installation, ensure that the multiple support legs 7 are evenly distributed on the bottom surface of the drying chamber 1 to form a stable support structure. The length of the support legs 7 is designed according to the installation environment and usage requirements of the equipment. Rubber pads or adjusting bolts can be installed at the bottom to adapt to different ground conditions and ensure that the equipment is placed horizontally.

[0048] During equipment operation, the rotary motor 13 drives the main heat pipe 11 and the secondary heat pipe 10 to rotate at high speed, generating significant vibration and force. Multiple equidistant support legs 7 effectively disperse these forces, evenly transmitting the vibrations and forces generated during equipment operation to the ground, preventing the drying chamber 1 from shaking or tilting, and ensuring the stability and safety of the equipment operation. Simultaneously, the reasonable layout of the support legs 7 keeps the drying chamber 1 level, which is beneficial for the even distribution and drying of plastic granules within the drying chamber 1, preventing uneven accumulation of plastic granules due to tilting of the drying chamber 1, which would affect the drying effect and ensure that the plastic granules receive comprehensive and uniform drying treatment.

[0049] Example 3, see Figure 1-4 A controller 5 is installed on the outer surface of the drying oven 1.

[0050] The controller 5 is fixed to a pre-installed mounting bracket on the outer surface of the drying oven 1 by bolts or clips, and the installation position is convenient for operators to operate and observe. The controller 5 integrates control circuits, sensor interfaces and other components, and is connected to the rotary motor 13, hot air source and other equipment via wires. During the connection process, the wires pass through the side wall of the drying oven 1 through sealed joints, which ensures both circuit continuity and maintains the airtightness of the drying oven 1.

[0051] Operators can adjust and control parameters such as the rotation speed of the rotary motor 13, the temperature of the hot air source, and the hot air flow rate through the display screen and operation buttons on the controller 5. The intelligent control system built into the controller 5 can precisely control the operating status of each piece of equipment according to preset programs or operator instructions. Through the intelligent control of the controller 5, the operating parameters of the equipment can be flexibly adjusted according to the drying requirements of different types and humidity levels of plastic granules, achieving personalized and precise drying treatment, and improving the intelligence level and ease of use of the equipment.

It is common knowledge in the field, and we will only use it without modifying it. Therefore, the control method and circuit connection will not be described in detail.
