Description

Technical Field

[0001] The utility model relates to a furnace, in particular to an installation structure of a magnetic stirrer for a furnace. Background Art

[0002] A furnace generally refers to a device used to melt metals or other substances, which can turn solid substances into liquids through high temperatures. In metallurgy, casting and other industrial production processes, furnaces are indispensable and important devices.

[0003] For example, a permanent magnet stirring alloy electric furnace disclosed in a Chinese patent (CN201104121Y) has a permanent magnet stirring magnetic steel wheel arranged directly below the bottom of the furnace. It is driven by a motor to rotate, and the formed magnetic force is used to stir the metal solution. The rotation speed and time are adjusted and controlled through a speed control operation box. Without directly contacting the metal solution, the purpose of stirring can be achieved, and the stirring is uniform. The consumption of equipment and raw materials is reduced, and the yield is improved.

[0004] However, in the above patent, since the permanent magnet stirring magnetic steel wheel is fixed below the furnace and the stirring inside the furnace is realized by rotating the permanent magnet stirring magnetic steel wheel, when maintaining the equipment, due to the high temperature of the furnace, it is necessary to wait for the temperature inside the furnace to decrease, and then the disassembly of the permanent magnet stirring magnetic steel wheel is completed through multiple steps, thereby realizing the maintenance of the permanent magnet stirring magnetic steel wheel. Due to the cumbersome maintenance steps, the overall maintenance efficiency of the equipment is low; and due to the too high temperature of the furnace, the permanent magnet stirring magnetic steel wheel will be demagnetized when it is in a high-temperature environment for a long time, resulting in the inability of the permanent magnet stirring magnetic steel wheel to operate stably in a high-temperature environment.

[0034] The following combines Figures 1 to 7 , to describe an installation structure of a magnetic stirrer for a furnace in an embodiment of the present utility model.

[0035] An installation structure of a magnetic stirrer for a furnace, the magnetic stirrer 4 is movably installed in the processing chamber 1 below the furnace. It is characterized in that a moving component 2 is installed at the bottom of the inner wall of the processing chamber 1. The moving component 2 is provided with casters 12, a moving plate 11 and a top rod 5. The caster 12 is externally connected to a power source. The caster 12 drives the slider 10 to move along the length direction of the chute 9, so as to make the whole moving component 2 move. A supporting component 3 is fixedly installed on the upper surface of the moving plate 11. The supporting component 3 is provided with a connecting plate 28. A magnetic stirrer 4 corresponding to the furnace is fixedly installed on the upper surface of the connecting plate 28. The magnetic stirrer 4 stirs the inside of the furnace. After the moving component 2 drives the magnetic stirrer 4 on the supporting component 3 to move under the furnace, it is fixed, and the supporting component 3 is unfolded to make the magnetic stirrer 4 reach a proper distance from the furnace. A top rod 5 is slidably installed on the inner wall of the chute 9 corresponding to the slider 10. One end of the top rod 5 far from the inner wall of the chute 9 is fixedly provided with a circular plate 6. A first spring 7 is sleeved on the outer surface of the top rod 5. The two ends of the first spring 7 are respectively fixedly connected to the side surface of the circular plate 6 and the inner wall of the chute 9. The circular plate 6 and the first spring 7 cooperate with each other to buffer the moving plate 11 in the moving component 2.

[0036] As Figures 3 - 5 As shown in the figure, the moving component 2 includes a bottom plate 8. A chute 9 is opened on the upper surface of the bottom plate 8. A slider 10 is arranged inside the chute 9. A plurality of casters 12 are fixedly installed on the bottom surface of the slider 10. The plurality of casters 12 are symmetrically distributed with the center line of the slider 10 as the symmetry axis;

[0037] A plurality of installation grooves 13 are opened on the inner wall of the chute 9. The plurality of installation grooves 13 are symmetrically distributed with the center line of the chute 9 as the symmetry axis. Electric push rods 14 are fixedly installed and limited on the inner walls of the installation grooves 13. One end of the electric push rod 14 close to the slider 10 is fixedly provided with a push plate 15 corresponding to the installation groove 13. An insertion rod 16 is fixedly installed on the side of the push plate 15 far from the electric push rod 14. Insertion grooves 17 corresponding to the insertion rod 16 are respectively opened on the two side surfaces of the slider 10. A second spring 18 is sleeved on the outer surface of the electric push rod 14. The two ends of the second spring 18 are respectively fixedly connected to the side surface of the push plate 15 and the inner wall of the installation groove 13. The second spring 18 pushes the insertion rod 16 to be in contact with the side surface of the slider 10 in real time, so that the insertion rod 16 quickly enters the insertion groove 17, thereby completing the fixation of the slider 10. When the slider 10 needs to be unlocked, the electric push rod 14 contracts to make the insertion rod 16 leave the insertion groove 17, thereby completing the unlocking of the slider 10;

[0038] The slider 10 is arranged on the bottom surface of the moving plate 11.

[0039] As Figures 4 - 5As shown in the figure, two slide rails 19 are fixedly installed on the upper surface of the bottom plate 8. The two slide rails 19 are respectively slidably connected to the moving plate 11. The moving plate 11 can perform a stable linear motion under the guidance of the slide rails 19, thereby further ensuring the accurate movement and positioning of the magnetic stirrer 4 in the furnace. The moving plate 11 is provided with rotating grooves 20 corresponding to the slide rails 19. A number of rollers 21 are installed in the rotating grooves 20. The number of rollers 21 is linearly distributed along the length direction of the rotating grooves 20;

[0040] The rollers 21 cooperate with the top surface of the slide rails 19 to further support the moving plate 11 and reduce the frictional resistance when the moving plate 11 slides on the slide rails 19, improving the smoothness of the sliding.

[0041] As Figure 6 shown in the figure, the support assembly 3 includes a fixed plate 22. The fixed plate 22 is fixedly connected to the moving plate 11. A receiving groove 23 is formed on the upper surface of the fixed plate 22. At both ends of one side of the inner wall of the receiving groove 23, first connecting rods 24 are respectively hinge-mounted. At both ends of the other side of the inner wall of the receiving groove 23, second connecting rods 25 are respectively installed through connecting shafts, and the first connecting rods 24 and the second connecting rods 25 are hinge-connected. A support shaft 26 is fixedly installed on the side where the two second connecting rods 25 are close to each other. A telescopic drive rod 27 is sleeved on the outer surface of the support shaft 26. The other end of the telescopic drive rod 27 is hinge-connected to the inner wall of the receiving groove 23. A connecting plate 28 is provided at the top ends of the first connecting rods 24 and the second connecting rods 25. The connecting plate 28 is hinge-connected to both the first connecting rods 24 and the second connecting rods 25. When the telescopic drive rod 27 expands, it pushes the second connecting rod 25 to rotate. The second connecting rod 25 drives the first connecting rod 24 to rotate, so that the connecting plate 28 moves in the vertical direction, and further raises the magnetic stirrer 4 to a suitable position;

[0042] The magnetic stirrer 4 is fixed to the top surface of the connecting plate 28.

[0043] As Figures 2 - 4 shown in the figure, an arc surface is provided at one end of the insertion rod 16 close to the slider 10, and the arc surfaces on both sides of the chute 9 are mirror-symmetrical based on the center line of the chute 9. The arc surface helps the sliding between the insertion rod 16 and the slider 10 and helps reduce the probability of equipment damage.

[0044] As Figure 7 shown in the figure, a through groove 29 is formed through the inner wall of the processing chamber 1 behind the furnace. An air inlet pipe 30 is fixedly installed at the through groove 29. A fixed frame 31 is fixedly installed at the outer end of the air inlet pipe 30. A drive shaft 32 is rotatably installed on the inner wall of the fixed frame 31. A fan 33 is fixedly installed on the drive shaft 32.

[0045] As Figure 7As shown, a baffle 34 is fixedly installed at the through groove 29. The baffle 34 prevents the fan blade 33 from contacting the staff, preventing the staff from being injured, and at the same time preventing parts from entering the fan blade and damaging the equipment.

[0046] Working principle: During the process of the casters 12 driving the slider 10 to move to a suitable position, the slider 10 pushes the insertion rod 16 along the uphill surface of the insertion rod 16. The second spring 18 pushes the push plate 15 so that the insertion rod 16 is in contact with the sliding plate in real time, so that the insertion rod 16 can quickly enter the insertion slot 17 to fix the slider 10. After reaching the appropriate range, while the telescopic drive rod 27 expands, it pushes the second connecting rod 25 to rotate. The second connecting rod 25 drives the first connecting rod 24 to rotate, so that the connecting plate 28 moves in the vertical direction, and then the magnetic stirrer 4 rises to a suitable position; when the magnetic stirrer 4 needs to dissipate heat after processing, the electric push rod 14 drives the insertion rod 16 out of the insertion slot 17. The casters 12 drive the upper moving plate 11 of the slider 10 to move to the ventilation pipe, and the drive shaft 32 drives the fan blade 33 to rotate at a high speed, so that the gas with a lower external temperature cools the magnetic stirrer 4.

[0047] Other components and operations of the installation structure of a furnace magnetic stirrer according to an embodiment of the present invention are known to those of ordinary skill in the art and will not be described in detail here.
