Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically to an FEP particle deheating and cooling device. Background Technology

[0002] FEP, short for fluorinated ethylene propylene copolymer, is a copolymer of tetrafluoroethylene and hexafluoropropylene. FEP can be used in soft plastics, but its tensile strength, abrasion resistance, and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant over a wide temperature and frequency range. FEP particles typically require cooling during production. Traditional cooling devices cool FEP particles directly through airflow. However, when FEP particles are laid in a thick layer, those in the middle and lower parts are difficult to cool properly, resulting in uneven cooling and poor cooling effect. To improve the cooling of FEP particles, a deheating and cooling device for FEP particles is proposed.

[0003] As disclosed in the authorization announcement number CN222096642U, a recycled plastic particle cooling device includes a mounting frame. A leveling assembly is installed inside the mounting frame. The leveling assembly includes a reciprocating screw rotatably connected to one side of the inner wall at both ends of the mounting frame. A movable plate is externally threaded to the reciprocating screw. A slider adapted to the reciprocating screw is provided inside the movable plate. A limiting rod is slidably inserted into each side of the movable plate. Both ends of the two limiting rods are fixedly connected to the inner walls at both ends of the mounting frame. A motor is fixedly installed on the outer wall at one end of the mounting frame. The motor shaft is coaxially fixed to one end of the reciprocating screw. A telescopic rod is fixedly connected to one side of the bottom outer wall of the movable plate. Although it achieves the goal of pushing the accumulated part to the empty space after the raw material is poured on the top of the conveyor belt by setting up a leveling component, so that the raw material is evenly spread on the top of the conveyor belt and the cooling of the raw material is sufficiently uniform. However, this does not solve the problem that existing cooling equipment is not conducive to heat exchange, absorption, deheating, and cooling of FEP particles during use, nor is it conducive to sufficient stirring of FEP particles to make their cooling more uniform, thus affecting the deheating and cooling effect of FEP particles. Utility Model Content

[0004] The purpose of this invention is to provide an FEP particle deheating and cooling device to solve the problems mentioned in the background art, such as the inconvenience of the cooling device for heat exchange absorption and deheating of FEP particles, the difficulty in fully stirring the FEP particles to make the cooling more uniform, and the impact on the deheating and cooling effect of FEP particles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an FEP particle deheating and cooling device, comprising a cooling box and a cooling block, wherein the cooling block is provided on the outer surface of the cooling box, a placement frame is provided at the top of the cooling box, a movable frame is slidably provided at the bottom of the placement frame, two sets of hydraulic rods are symmetrically provided at the bottom of the movable frame, a push arm is installed at the output end of each hydraulic rod, a movable block is provided at the end of each push arm away from the hydraulic rod, and the movable block is slidably connected to the movable frame, and an adjustment frame is provided between the two sets of movable blocks, a first servo motor is installed at the top of each adjustment frame, a first drive shaft is installed at the output end of each first servo motor, multiple sets of stirring frames are movably provided at equal intervals at the bottom of each adjustment frame, and the first drive shaft is connected to one set of stirring frames, a sprocket and chain assembly is provided on the surface of each stirring frame, and the stirring frames are interconnected through the sprocket and chain assembly, and a solenoid valve is provided at the bottom of the cooling box.

[0009] Preferably, a connecting rod is provided at the end of the linkage arm away from the adjusting arm, and a hinge shaft is provided at the end of the connecting rod near the linkage arm, and the connecting rod is movably connected to the linkage arm through the hinge shaft.

[0012] Preferably, a controller is provided on the outer wall of the cooling box, and the output end of the controller is electrically connected to the input ends of the solenoid valve, the first servo motor, the hydraulic rod, and the second servo motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cooling device not only realizes heat exchange absorption and deheating cooling of FEP particles, but also facilitates full stirring of FEP particles to make their cooling more uniform, and improves the deheating and cooling effect of FEP particles.

[0014] (1) Pour the FEP particles that need to be cooled into the interior of the cooling box. The heat of the FEP particles is transferred to the interior of the cooling block through the cooling box. Cold water is injected into the serpentine copper tube through the liquid inlet pipe. The cold water flows in the serpentine copper tube and exchanges heat, absorbing the heat of the FEP particles and being discharged from the liquid outlet pipe. The first servo motor drives a set of stirring racks to rotate through the first drive shaft. Under the linkage of the sprocket and chain assembly, the set of stirring racks drives the other sets of stirring racks to rotate synchronously through the sprocket and chain assembly. The stirring racks stir the FEP particles in the cooling box. Simultaneously, the hydraulic rod is opened and closed repeatedly, which drives the push arm to move back and forth. The push arm drives the moving block to slide back and forth on the surface of the moving frame. The moving block drives the stirring frame to move back and forth through the adjusting frame, so as to stir the FEP particles longitudinally and change the position of the FEP particles so that they can fully contact the inner wall of the cooling box. In this way, the heat of the FEP particles can be quickly transferred and discharged, thereby completing the deheating and cooling of the FEP particles. This realizes the heat exchange absorption and deheating cooling of FEP particles, and facilitates the full stirring of FEP particles so that the cooling is more uniform. (2) The second servo motor drives the adjusting arm to rotate through the second drive shaft. The adjusting arm drives the linkage arm to swing back and forth through the pin shaft. The linkage arm drives the connecting rod to slide inside the limit block through the hinge shaft. The connecting rod drives the moving frame to slide at the bottom of the placement frame. The moving frame drives the stirring frame to swing back and forth laterally in the cooling box to stir the FEP particles more thoroughly and accelerate their deheating and cooling speed. The temperature of the FEP particles is detected by a handheld temperature detector. If the temperature is within the qualified range, the solenoid valve is opened to discharge the FEP particles from the cooling box to improve the deheating and cooling effect of the FEP particles.

The adjusting arm 23 drives the linkage arm 24 to swing back and forth through the pin shaft 25. Under the sliding cooperation of the limit block 11 and the connecting rod 9, the linkage arm 24 drives the connecting rod 9 to slide inside the limit block 11 through the hinge shaft 26. The connecting rod 9 drives the moving frame 8 to slide at the bottom of the placement frame 3. The moving frame 8 drives the stirring frame 7 to swing back and forth laterally in the cooling box 4 to more fully stir the FEP particles and accelerate their deheating and cooling speed.
