Description

Technical Field

[0001] This utility model relates to the field of polymer material processing technology, specifically to a double-sided cooling and conveying device for cross-linked polyethylene wax particles. Background Technology

[0002] Cross-linked polyethylene wax (CLPE wax) is a type of polyethylene wax that is cross-linked through chemical or physical methods. Its molecular chains form a three-dimensional network structure, which endows the material with excellent heat resistance, mechanical strength and chemical stability.

[0003] In the production of cross-linked polyethylene wax, the cooling process is a critical step affecting product performance. Traditional cooling methods often employ single-sided cooling conveyor devices, such as liquid-cooled plate single-sided cooling technology. This technology achieves heat transfer through the flow of liquid inside a metal plate. Although it is more efficient than traditional air cooling, it has the following limitations: single-sided cooling can only provide contact cooling to the bottom or a single surface of the particles. This results in heat accumulation on the top or other side of the particles due to the lack of a direct heat exchange path, which can easily lead to localized overheating. It can also cause excessively high surface temperatures on the conveyor devices used for transport. Consequently, after prolonged operation, the temperature of the side of the cross-linked polyethylene wax particles in contact with the conveyor belt is uneven with the cooling surface on the other side.

[0014] (III) Beneficial Effects

[0015] This invention provides a double-sided cooling and conveying device for cross-linked polyethylene wax particles. It features the following:

[0016] Beneficial effects:

[0017] 1. This solution achieves the first direct cooling of the inner surface of the conveyor belt by the embedded cooling water distribution pipe and spray hole design. Subsequently, the cooling water falls naturally to the outer surface under the action of gravity, forming a secondary cooling of the conveyor belt and the bottom of the particles.

Detailed Implementation

[0025] This utility model provides a double-sided cooling and conveying device for cross-linked polyethylene wax particles, such as... Figure 1-5As shown, the system includes a side support frame 101, shock-absorbing support feet 102, drive rollers 107, a double-layer cooling conveyor belt 108, and a feed hopper 109. The feed hopper 109 is fixedly installed on one side of the side support frame 101. Several shock-absorbing support feet 102 are fixedly connected to the bottom of the side support frame 101 and the bottom of the feed hopper 109, providing stable support. Two drive rollers 107 are rotatably installed between the two side support frames 101. A double-layer cooling conveyor belt 108 is wound between the outer end faces of the two drive rollers 107. The side support frame 101 has outward-facing opening slots 123 on both sides, which are symmetrically positioned. Several cooling water distribution pipes 105 are installed between the crossbeam supports 104. The cooling water distribution pipes 105 are arranged in an array, and the outer end faces of the cooling water distribution pipes 105 are connected to several upward-facing spray holes 103, which are also arranged in an array.

[0026] It should be noted that the cooling water distribution pipe 105 and the spray hole 103 are located between the inner rings of the double-layer cooling conveyor belt 108, and the spray hole 103 opens upwards.

[0027] Furthermore, the main water inlet pipe 122 of the crossbeam support 104 on one side is fixed thereon. The main water inlet pipe 122 is connected to the cooling water distribution pipes 105 on each side and is connected to the water inlet pipe.

[0028] It is worth further explaining that after the main water inlet pipe 122 is connected to the water inlet pipe, when the water inlet pipe is opened by the staff, cold water is input into the cooling water distribution pipes 105 on each side through the main water inlet pipe 122. The cooling water is then directed upward and sprayed out through the spray holes 103 on each side connected to the cooling water distribution pipes 105, cooling the upper belt of the inner surface of the double-layer cooling conveyor belt 108. Subsequently, the cooling water falls downward to the inner surface of the lower double-layer cooling conveyor belt 108 under the action of gravity, and performs secondary cooling on the double-layer cooling conveyor belt 108, thereby achieving the cooling effect of the double-layer cooling conveyor belt 108 during operation.

[0029] Furthermore, a conveyor belt drive motor 106 is fixedly installed on one side of the side support frame 101, and the conveyor belt drive motor 106 is poweredly connected to the transmission roller 107 on one side.

[0030] It is worth further explaining that the motor shaft of the conveyor belt drive motor 106 is installed and connected to the drive shaft of the drive roller 107. When the conveyor belt drive motor 106 starts, it can drive the drive roller 107 to rotate through the power transmission of the motor shaft, and through the cooperation of the drive roller 107 on the other side, drive the double-layer cooling conveyor belt 108 to move, and achieve the effect of conveying cross-linked polyethylene wax particles.

[0031] Furthermore, the feed hopper 109 is provided with a particle buffer chamber 110, which is connected to the output port of the cross-linked polyethylene wax particle production equipment. An inclined guide plate 111 is installed on one side of the bottom of the particle buffer chamber 110.

[0032] It should be further explained that the inclined guide plate 111 is used to guide the cross-linked polyethylene wax particles toward the surface of the double-layer cooling conveyor belt 108.

[0033] Furthermore, sensor brackets 120 are fixedly installed on both sides of the bottom of the side support frame 101, and infrared temperature sensors 119 are installed on the top of the sensor brackets 120. The infrared temperature sensors 119 on both sides are used to monitor the surface temperature at both ends of the double-layer cooling conveyor belt 108. A smart temperature control host 121 is fixedly installed at the bottom of the feed hopper 109, and the smart temperature control host 121 is connected to the infrared temperature sensors 119 on both sides.

[0034] It should be further explained that the intelligent temperature control host 121 is used to connect to the cross-linked polyethylene wax particle producer and can control the rotation speed of the conveyor belt drive motor 106.

[0035] It is worth further explaining that during the production and cooling transportation of cross-linked polyethylene wax granules, the infrared temperature sensors 119 on both sides detect the temperature of the surface of the double-layer cooling conveyor belt 108 and transmit the temperature values ​​from both sides to the intelligent temperature control host 121 for data acquisition. When the infrared temperature sensor 119 detects that the surface temperature of the double-layer cooling conveyor belt 108 is too high, the intelligent temperature control host 121 sends a command to the conveyor belt drive motor 106 to slow down its rotation speed, thereby slowing down the movement speed of the double-layer cooling conveyor belt 108. This increases the residence time of the cross-linked polyethylene wax granules on the conveying device and achieves a temperature reduction effect by increasing the heat dissipation time. At the same time, the intelligent temperature control host 121 controls and slows down the production output speed of the cross-linked polyethylene wax granule producer to coordinate with the temperature control adjustment of the conveying device.

[0036] Furthermore, a number of fan support columns 113 are mounted on the top of the side support frame 101. The fan support columns 113 are arranged in an array. A number of inclined air plates 114 are installed on the top of the fan support columns 113. The inclined air plates 114 are inclined and their openings face the surface of the double-layer cooling conveyor belt 108.

[0037] Furthermore, a centrifugal fan assembly 118 is rotatably installed inside the inclined air plate 114, and a fan motor 116 is fixedly installed on one side of the inclined air plate 114. The motor shaft of the fan motor 116 is installed and connected to the rotation center of the centrifugal fan assembly 118.

[0038] It should be further explained that when the fan motor 116 starts, it can output power through the motor shaft and drive the centrifugal fan assembly 118 to rotate, thereby providing a cooling effect on the upper surface of the cross-linked polyethylene wax particles conveyed on the surface of the double-layer cooling conveyor belt 108.

[0039] The usage method of this solution is as follows:

[0040] S1. Connect the main water inlet pipe 122 to the external cooling water source, turn on the power of the intelligent temperature control host 121, and set the surface temperature threshold of the conveyor belt 108 through the temperature control host 121.

[0041] S2. The cross-linked polyethylene wax particles produced upstream fall into the feed hopper 109. After being buffered by the buffer chamber 110, they are guided by the inclined guide plate 111 to the surface of the conveyor belt 108. At this time, the conveyor belt drive motor 106 starts and drives the transmission roller 107 to rotate through the power transmission of the motor shaft. Through the cooperation of the transmission roller 107 on the other side, the double-layer cooling conveyor belt 108 is moved, and the effect of conveying cross-linked polyethylene wax particles is achieved.

[0042] S3. When the dual-sided cooling works in synergy, the cooling water enters the cooling water distribution pipe 105 through the main water inlet pipe 122 and is sprayed upward through the array of spray holes 103. The water flow first contacts the inner surface of the conveyor belt 108 for initial cooling. At the same time, the cooling water falls under gravity and covers the outer surface of the conveyor belt 108 and the bottom surface of the particles to achieve secondary cooling.

[0043] At the same time, the fan motor 116 is started to drive the centrifugal fan group 118, and the airflow blows directionally onto the upper surface of the particles through the inclined air duct 114 to enhance the heat dissipation at the top.

[0044] S4. During this process, the infrared temperature sensor 119 monitors the temperature at both ends of the conveyor belt 108 in real time. When the infrared temperature sensor 119 detects that the surface temperature of the double-layer cooling conveyor belt 108 is too high, the intelligent temperature control host 121 will send a command to the conveyor belt drive motor 106 to slow down its rotation speed, thereby slowing down the movement speed of the double-layer cooling conveyor belt 108, increasing the residence time of the cross-linked polyethylene wax particles on the conveying device, and achieving a temperature reduction effect by increasing the heat dissipation time. At the same time, the intelligent temperature control host 121 controls and slows down the production output speed of the cross-linked polyethylene wax particle producer to coordinate with the temperature control adjustment of the conveying device.

[0045] S5. After production is completed, shut off the feed. After the conveyor belt 108 is emptied, shut off the drive motor 106 and the fan 116. Use a soft brush to remove the particle residue and complete the double-sided cooling and conveying of the cross-linked polyethylene wax particles.
