Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a cooling device for finished PE board particles. Background Technology

[0002] PE sheet finished particles are the final form of plastic granules used in the production of polyethylene sheets. These particles are processed through specific techniques, possessing uniform dimensions and stable properties. They are a key raw material for manufacturing high-quality PE sheets, playing a crucial role in extrusion, shaping, and cooling processes to ensure that the physical properties and appearance quality of the final product meet expected standards. Widely used in industry, construction, packaging, and other fields, they are highly favored for their excellent corrosion resistance, abrasion resistance, and impact resistance.

[0003] During the production of PE boards, the temperature of the finished PE board particles is often high when they are first produced. This is because the particles have undergone high-temperature melting, extrusion, and pelletizing processes during production, and they carry a large amount of heat. If they are directly piled up after production, the heat inside the particles is difficult to dissipate, leading to heat accumulation. As time goes by, the temperature in the center of the accumulation continues to rise. When it reaches the ignition point of the finished PE board particles, it is very likely to cause combustion. This risk of combustion caused by excessively high temperature not only seriously threatens the safety of production facilities and is prone to causing fires and significant property losses, but also poses a direct threat to the lives of production personnel. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cooling device for finished PE board particles, which aims to improve the problem that existing finished PE board particles, when directly stacked after production, will burn due to excessively high temperatures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for finished PE board particles, comprising a support frame and a cooling pipe to provide space for cooling the finished PE board particles; a cooling mechanism installed inside the support frame for cooling the finished PE board particles, including a cooling water inlet mechanism, a transport mechanism, and a stirring mechanism; the transport mechanism for transporting the finished PE board particles; the stirring mechanism for ensuring sufficient contact between the finished PE board particles and the coolant to accelerate the cooling of the finished PE board particles; and a discharge mechanism for discharging the cooled finished PE board particles; the transport mechanism includes a motor and a belt assembly, the motor driving a rotating shaft to rotate via the belt assembly, the rotating shaft being rotatably connected inside the cooling pipe, and an auger blade being fixedly connected to the outer wall of the rotating shaft; the stirring mechanism includes a stirring rod rotatably connected inside the cooling pipe, a second gear being fixedly connected to the outer wall of the cooling pipe, and a first gear being fixedly connected to the outer wall of the rotating shaft, the first gear meshing with the second gear.

[0006] Furthermore, an installation plate is fixedly connected to the outer wall of the cooling pipe for connecting the cooling device to the PE board finished particle extrusion device.

[0007] Furthermore, the discharge mechanism includes a connecting pipe and a fan. The fan is installed on the top of the support frame. One end of the connecting pipe is connected to the inside of the support frame, and the other end is connected to the input end of the fan. The output end of the fan is fixedly connected to the discharge pipe.

[0008] Furthermore, the cooling water inlet mechanism includes a connector and a water pipe, the connector being installed inside the cooling pipe, and the water pipe being used for the inlet of coolant.

[0009] Furthermore, a fixing sleeve is fitted on the outer wall of the water pipe, and the fixing sleeve is connected to the connector by means of a thread on the outer wall of the connector.

[0010] Furthermore, a sealing plate is fixedly connected to one end of the water pipe, and the sealing plate can be snapped into a slot opened inside the connector.

[0011] Furthermore, a sealing ring is fixedly connected to the bottom of the sealing sheet, and the sealing ring can be inserted into the second slot opened inside the connector.

[0012] Furthermore, a filter screen is fixedly connected inside the motor to prevent particles from the finished PE board from entering the water pipe.

[0013] This utility model has the following beneficial effects: 1. In this utility model, through the synergistic action of the transport mechanism and the stirring mechanism, while the auger blades transport the particles, the stirring rod fully stirs the particles and coolant, which greatly increases the contact area and contact time between the particles and the coolant, accelerates the heat exchange speed, and can quickly reduce the temperature of the finished PE board particles, effectively avoiding the high-temperature combustion problem caused by insufficient heat dissipation due to accumulation, and ensuring production safety.

[0014] 2. In this utility model, the cooling water inlet mechanism achieves a stable connection through a multi-seal structure, and at the same time, it uses a filter screen to prevent particles from entering the water pipe, thereby preventing pipe blockage caused by particle accumulation. This not only improves the stability and reliability of the mechanism, but also ensures a smooth supply of coolant. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a cooling device for finished PE board particles, including a support frame 1 and a cooling pipe 2, providing space for cooling the finished PE board particles; a cooling mechanism, installed inside the support frame 1, for cooling the finished PE board particles, including a cooling water introduction mechanism, a transport mechanism, and a stirring mechanism; the transport mechanism is used for transporting the finished PE board particles; the stirring mechanism is used for ensuring sufficient contact between the finished PE board particles and the coolant, accelerating the cooling of the finished PE board particles; and a discharge mechanism is used for discharging the cooled finished PE board particles; the transport mechanism includes a motor 7 and a belt assembly 9, the motor 7 drives a rotating shaft 10 to rotate through the belt assembly 9, the rotating shaft 10 is rotatably connected inside the cooling pipe 2, and an auger blade 14 is fixedly connected to the outer wall of the rotating shaft 10; the stirring mechanism includes a stirring rod 13, the stirring rod 13 is rotatably connected inside the cooling pipe 2, a gear 2 12 is fixedly connected to the outer wall of the cooling pipe 2, and a gear 11 is fixedly connected to the outer wall of the rotating shaft 10, the gear 11 meshing with the gear 2 12; Specifically, during the operation of the PE board finished particle cooling device, the PE board finished particles first enter the cooling pipe 2 through the mounting plate 3 connected to the PE board finished particle extrusion device. Subsequently, these particles are transported along the cooling pipe 2 by the transport mechanism. During this process, the stirring mechanism plays an important role, which helps the coolant to fully contact the particles, thereby achieving an effective cooling effect. Finally, the cooled particles are smoothly discharged by the discharge mechanism.

[0019] To ensure the smooth progress of the cooling process, the cooling water inlet mechanism provides the necessary coolant. When transporting the finished PE board particles inside the cooling pipe 2, the motor 7 starts to run and drives the rotating shaft 10 to rotate through the belt group 9. As the rotating shaft 10 rotates, the auger blades 14 on its outer wall also rotate. Utilizing the spiral propulsion characteristics of the auger blades 14, the finished PE board particles entering the cooling pipe 2 can be continuously pushed forward.

[0020] While the rotating shaft 10 rotates, the gear 11 fixed on its outer wall also rotates synchronously. Since the gear 11 meshes with the gear 12 fixed on the outer wall of the stirring rod 13, the stirring rod 13 is also driven to rotate. During the rotation, the stirring rod 13 will fully stir the PE board finished particles and coolant in the cooling pipe 2, so that the particles and coolant can contact each other to the maximum extent, thereby accelerating the heat exchange rate and significantly improving the cooling efficiency.

[0021] When the finished PE board particles need to be discharged, the fan 5 will start, creating a negative pressure environment in the cooling pipe 2. Under the action of the transport mechanism, the cooled finished PE board particles are transported to the discharge position, then sucked in by the fan 5 through the connecting pipe 4, and finally discharged through the discharge pipe 6, completing the entire particle discharge operation.

[0022] During the cooling process, the coolant is introduced through water pipe 15. A fixing sleeve 17 is provided on the outer wall of water pipe 15. This fixing sleeve is connected via threads 16 on the connector 8 of cooling pipe 2, ensuring a secure fixation between water pipe 15 and connector 8. To ensure a tight seal during connection, a sealing plate 18 at one end of water pipe 15 engages with a groove 20 inside connector 8, while a sealing ring 19 at the bottom engages with a groove 21. Furthermore, a filter screen 22 is provided inside connector 8 to prevent PE board particles from entering water pipe 15, effectively avoiding blockages.

[0023] Working Principle: When the PE board finished particle cooling device is working, the PE board finished particles enter the cooling pipe 2 from the mounting plate 3 connected to the PE board finished particle extrusion device. They are then transported by the conveying mechanism, and the stirring mechanism assists in ensuring the coolant fully contacts and cools the particles. Finally, the cooled particles are discharged by the discharge mechanism. The cooling water inlet mechanism provides coolant for cooling. During the transport of the PE board finished particles inside the cooling pipe 2, the motor 7 operates, driving the rotating shaft 10 to rotate via the belt assembly 9. The auger blades 14 on the outer wall of the rotating shaft 10 rotate accordingly. Utilizing the spiral propulsion characteristic of the auger blades 14, the PE board finished particles entering the cooling pipe 2 are continuously transported forward. When the rotating shaft 10 rotates, the gear 11 fixed on its outer wall rotates synchronously. Because gear 11 meshes with gear 12 fixed on the outer wall of the stirring rod 13, it drives the stirring rod 13 to rotate. During the rotation of the stirring rod 13, the PE board finished particles and coolant inside the cooling pipe 2 are stirred. This allows the particles to fully contact the coolant, accelerating heat exchange and improving cooling efficiency. When the finished PE board particles are discharged, the fan 5 is started, creating a negative pressure in the cooling pipe 2. After cooling, the finished PE board particles reach the discharge position under the action of the transport mechanism, are sucked in by the fan 5 through the connecting pipe 4, and then discharged through the discharge pipe 6, completing the particle discharge operation. During cooling, the coolant is introduced through the water pipe 15. The fixing sleeve 17 on the outer wall of the water pipe 15 is connected by the thread 16 on the connector 8 on the cooling pipe 2, fixing the water pipe 15 to the connector 8, thereby realizing the introduction of coolant. The sealing plate 18 at one end of the water pipe 15 will be inserted into the first groove 20 inside the connector 8, and the bottom sealing ring 19 will be inserted into the second groove 21 to ensure the sealing during connection. At the same time, the filter screen 22 inside the connector 8 can prevent the finished PE board particles from entering the water pipe 15 and avoid blockage.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
