Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of heat dissipation devices for medium-frequency electric furnaces, and in particular to a structure for a medium-frequency electric furnace with a high-efficiency heat dissipation device. Background Technology
[0002] Medium frequency electric furnaces are commonly cooled using methods such as water cooling, air cooling, oil cooling, and hybrid cooling to ensure stable operation over long periods of time.
[0003] A search revealed a utility model patent with application number 202121195280.8, entitled "A Cooling Device for a Medium-Frequency Furnace." This patented device drives a water circulation component, which in turn drives the water circulation within a pipe assembly. The pipe assembly absorbs heat from the medium-frequency furnace, lowering its temperature. Simultaneously, a heat dissipation component cools the water within the pipe assembly, further reducing its temperature and achieving cyclical cooling. Excess heat from the pipe assembly can then be used to heat the workshop, saving production costs.
[0004] However, the heat exchange efficiency between the coil and the air is reduced due to the coil being too tightly packed during the heat dissipation process, which affects the heat dissipation effect of the device. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a medium-frequency electric furnace structure with an efficient heat dissipation device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A medium-frequency electric furnace structure with a high-efficiency heat dissipation device includes a base plate, a cooling mechanism above the base plate, a lifting plate above the lifting plate, a top plate above the lifting plate, a coil between the bottom of the top plate and the top of the lifting plate, a fixing frame surrounding the coil fixedly connected to the bottom of the top plate and the top of the lifting plate, a cooling pipe fixedly connected inside the coil, a motor fixedly connected to the top of the base plate, a lead screw fixedly connected to the output shaft of the motor, a lifting block threadedly connected to the circumferential side of the lead screw, and preferably, the top of the lifting block fixedly connected to the bottom of the lifting plate.
[0008] Preferably, the bottom of the top plate and the top of the lifting plate are rotatably connected to rotating ring plates, and an arc plate is fixedly connected between the two rotating ring plates. The circumferential side of the arc plate is evenly provided with openings.
[0009] Preferably, the circumferential side of the arc plate is uniformly and fixedly connected with connecting columns that are aligned with the openings, and the other end of the connecting column is fixedly connected with a second motor that is aligned with the opening. The output shaft of the second motor is fixedly connected with a rotating shaft, and the circumferential side of the rotating shaft is uniformly and fixedly connected with fan blades located inside the opening.
[0010] Preferably, the top of the base plate is uniformly and fixedly connected with support columns, the other end of the support columns is fixedly connected to the inside of the top plate, the circumferential side of the support columns is slidably connected to the inside of the lifting plate, and the top of the base plate is fixedly connected with a rotating cylinder.
[0011] Preferably, a rotating sleeve is fixedly connected to the top of the rotating cylinder, a connecting band is sleeved between the circumferential side of the rotating sleeve and the circumferential side of the lead screw, a movable shaft is slidably connected to the inner wall of the circumferential side of the rotating sleeve, and the circumferential side of the movable shaft is rotatably connected to the inside of the lifting plate.
[0012] Preferably, one end of the movable shaft extends to the circumferential side of the rotating ring plate, and a gear aligned with the rotating ring plate is fixedly connected to the circumferential side of the movable shaft, with the circumferential side of the gear meshing with the circumferential side of the rotating ring plate.
[0013] Preferably, the movable shaft has a circumferential side surface with a limit groove evenly provided, and the inner wall of the circumferential side surface of the rotating sleeve is evenly fixedly connected with a limit block aligned with the limit groove, and one side of the limit block is slidably connected to one side of the inner wall of the limit groove.
[0014] Compared with the prior art, this utility model provides a medium-frequency electric furnace structure with a high-efficiency heat dissipation device, which has the following beneficial effects:
[0015] After the coil heating process is completed, the workpiece between the coils is removed via a lifting plate. Simultaneously, coolant is continuously circulated through the cooling pipes to cool the coils. During the heating interval, motor one is activated. Motor one drives a lead screw to rotate, which in turn moves a lifting block. The lifting block moves a fixed frame, which in turn stretches the coil. This helps prevent the coil from becoming too tightly packed during heat dissipation, which would reduce heat exchange efficiency between the coil and the air and affect the device's heat dissipation effect. Motor two is then activated, driving a rotating shaft to rotate. The shaft in turn rotates a fan blade, which blows airflow towards the coil, accelerating heat exchange between the coil and the air. Simultaneously, the increased distance between the coils during stretching allows for greater airflow contact, improving the device's heat dissipation. The lead screw, via a connecting belt, drives a rotating sleeve to rotate. The rotating sleeve drives a movable shaft to rotate, which in turn drives a rotating ring plate. The rotating ring plate drives an arc-shaped plate, which in turn drives motor two to rotate around the coil. This allows the fan blades to blow airflow to all corners of the coil, preventing situations where the front side of the coil can dissipate heat efficiently while the back side cannot, thus improving the device's heat dissipation effect.

[0022] In this utility model, the bottom of the top plate and the top of the lifting plate 7 are rotatably connected to rotating ring plates 11, and an arc plate 10 is fixedly connected between the two rotating ring plates 11. The circumferential side of the arc plate 10 is evenly provided with openings 19.
[0023] The circumferential side of the arc plate 10 is uniformly fixedly connected with connecting posts 21 aligned with openings 19. The other end of the connecting posts 21 is fixedly connected with a motor 20 aligned with openings 19. The output shaft of the motor 20 is fixedly connected with a rotating shaft 18. The circumferential side of the rotating shaft 18 is uniformly fixedly connected with fan blades 22 located inside openings 19.
[0024] Support columns 9 are evenly and fixedly connected to the top of the base plate 1. The other end of the support column 9 is fixedly connected to the inside of the top plate. The circumferential side of the support column 9 is slidably connected to the inside of the lifting plate 7. A rotating cylinder 5 is fixedly connected to the top of the base plate 1.
[0025] A rotating sleeve 17 is fixedly connected to the top of the rotating cylinder 5. A connecting band 4 is sleeved between the circumferential side of the rotating sleeve 17 and the circumferential side of the lead screw 3. A movable shaft 6 is slidably connected to the inner wall of the circumferential side of the rotating sleeve 17. The circumferential side of the movable shaft 6 is rotatably connected to the inside of the lifting plate 7.
[0026] One end of the movable shaft 6 extends to the circumferential side of the rotating ring plate 11. A gear 8 aligned with the rotating ring plate 11 is fixedly connected to the circumferential side of the movable shaft 6. The circumferential side of the gear 8 is meshed with the circumferential side of the rotating ring plate 11.
[0027] The movable shaft 6 has a circumferentially evenly spaced limiting groove 16.

[0028] Working principle: After the heating process of coil 13 is completed, the workpiece between coil 13 is removed. Simultaneously, coolant is continuously introduced through cooling pipe 23 to cool coil 13. During the interval between heating operations, motor 12 is started. Motor 12 drives lead screw 3 to rotate, which in turn moves lifting block 14. Lifting block 14 moves fixed frame 12, which in turn stretches coil 13. This helps prevent coil 13 from becoming too tightly packed during heat dissipation, which would reduce heat exchange efficiency between coil 13 and air and affect the device's heat dissipation effect. Motor 20 is then started, driving shaft 18 to rotate. Shaft 18 drives fan blades 22 to rotate, which in turn drives airflow. The airflow is directed towards coil 13, accelerating the heat exchange efficiency between coil 13 and the air. Simultaneously, the increased distance between coils 13 during stretching facilitates greater airflow contact with coil 13, improving the device's heat dissipation.

This allows fan blades 22 to direct airflow to all corners of coil 13, preventing situations where the front side of coil 13 can efficiently dissipate heat but the lee side cannot, thus improving the device's heat dissipation.
