Description

Technical Field

[0001] This utility model relates to the field of cooling, specifically to a high-temperature special plastic PEEK sheet and rod cooling device. Background Technology

[0002] PEEK is a high-performance engineering plastic with excellent heat resistance, chemical resistance, mechanical properties and abrasion resistance. It performs well in high-temperature environments and extreme conditions. PEEK sheets and rods are often used in applications requiring high strength, corrosion resistance and abrasion resistance.

[0003] Existing technologies have the following shortcomings: Current high-temperature special plastic PEEK sheet and rod cooling devices struggle to precisely and effectively control the cooling of high-temperature special plastic PEEK; existing cooling methods have poor adaptability to high-temperature special plastic PEEK; due to the properties of high-temperature special plastic PEEK, temperature changes significantly affect the plastic's strength, stiffness, and toughness; rapid or uneven temperature changes during cooling can lead to thermal stress, causing shape changes, cracks, or internal stress problems after cooling, thus affecting the efficiency and quality of high-temperature special plastic PEEK molding and processing. This has become one of the main problems users face when cooling high-temperature special plastic PEEK. Therefore, a wind-cooled water circulation cooling device is proposed to solve these problems.

[0004] Therefore, it is necessary to invent a high-temperature special plastic PEEK sheet and rod cooling device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature special plastic PEEK sheet and rod cooling device, comprising an air-cooling device housing, a heat exchange device housing, and a water-cooling box housing, characterized in that: a roller is installed on the top of the air-cooling device housing, a fan is installed below the roller, a cold water pipe is installed below the fan, the cold water pipe is connected to the heat exchange device inside the heat exchange device housing, a water tank is installed above the heat exchange device, the water tank collects wastewater flowing down from above, a small roller is installed in the opening of the water tank, a water pipe is installed above the small roller, a nozzle is installed on the water pipe, and the water pipe is enclosed within the water-cooling box housing.

[0006] Preferably, the cold water pipe is connected to the heat exchange device inside the housing of the heat exchange device, a water tank is installed on the top of the heat exchange device, three sets of filter pipes are installed at the bottom of the water tank, the three sets of filter pipes are connected to the bottom recovery water pipe, and the recovery water pipe is connected to the bottom heat exchange device.

[0007] Preferably, the water-cooled inlet pipe, the pipe inlet pipe, and the recovery water pipe are connected to one end of the heat exchange device, the heat exchange device continuously exchanges hot and cold water, and the end of the heat exchange device away from the water-cooled inlet pipe is connected to the water-cooled outlet pipe and the pipe outlet pipe.

[0008] Preferably, the top of the air-cooling device housing is equipped with rollers, the rollers have ventilation openings, and six sets of fans are installed below the rollers, the six sets of fans being connected by four sets of heat dissipation copper pipes spaced apart.

[0009] Preferably, the water-cooled box is enclosed by a casing containing water pipes, which are filled with cooling water. Five nozzles are installed on the water pipes, and the nozzles spray cooling water downwards.

[0010] Preferably, the nozzle on the water pipe sprays water mist downwards, the water mist flows downwards to a small roller, a water tank is installed below the small roller, the water tank collects the cooling water sprayed from the nozzle above, and a filter pipe is installed below the water tank.

[0011] The beneficial effects of this invention are as follows: During the molding and processing of high-temperature special plastic PEEK, if the temperature change during the cooling stage is too rapid or uneven, it may cause thermal stress problems, leading to shape changes, cracks, or even internal stress accumulation in the product after cooling. These problems significantly affect the processing efficiency and quality stability of the product. To address these challenges, an innovative solution is proposed: a combined air-cooling and water-cooling circulation device. This device effectively controls the cooling rate and temperature distribution of PEEK products by combining an air-cooling system and water-cooling circulation, ensuring uniform and stable temperature changes throughout the cooling process. This cooling technology not only significantly reduces the negative impact of thermal stress but also improves the molding accuracy and surface quality of the product, thereby increasing production efficiency and reducing processing costs.

A water tank 18 is installed on the top of the heat exchange device 21, and three sets of filter pipes 23 are installed at the bottom of the water tank. The three sets of filter pipes 23 are connected to the bottom recovery water pipe 24, which is connected to the bottom heat exchange device 21.

[0025] In the above embodiment, it should be noted that the water-cooled inlet pipe 16, the water inlet pipe 20, and the recovery water pipe 24 are connected to one end of the heat exchange device 21. The heat exchange device 21 continuously exchanges hot and cold water.

[0026] Example 3

[0028] In the above embodiment, it should be noted that the top of the air-cooling device housing 26 is equipped with a roller 25, and the roller 25 has a ventilation opening. The ventilation opening of the roller 25 allows the fan 13 below to blow cold air up.

Cooling water from the bottom cooling pipe 14 cools the air at the bottom. Then, fan 13 blows the cooled air upwards for the first stage of air cooling. After air cooling is completed, the roller continues to drive the material to the water pipe 11 in the water-cooling device, where nozzles 12 spray cooling water mist downwards. This cooling water mist cools the ultra-high temperature PEEK sheet / bar material. The cooled water flows downwards into the water tank 18. Three sets of filter pipes 23 are installed at the bottom of the water tank 18. After filtering the wastewater, the filter pipes 23 return the water to the heat exchange device 21 via the bottom recovery water pipe 24. Thus, the cooling of the ultra-high temperature PEEK sheet / bar material is completed by a combination of air cooling and water cooling circulation.
