[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The dust removal hood of the intermediate frequency furnace is used in conjunction with an electric telescopic rod, a threaded block and a fastening block. A controller is used to control the operation of the electric telescopic tube, so that the extended end of the electric telescopic tube drives the strip rod to rise and fall, and the height of the dust collecting device is adjusted. Subsequently, the threaded connection between the threaded hole provided on the upper end of the sliding rod and the threaded hole provided on the inner wall of the threaded block and the fastening block is made, and then the threaded block is rotated clockwise, so that the threaded block descends on the upper end of the sliding rod and fits with the top of the strip rod.

Subsequently, the fastening block is rotated clockwise on the upper end of the sliding rod, which can lead to tightening the threaded block, and then restricting the threaded block in place, so that the dust collecting device is fixed and restricted, thereby stably drawing and adsorbing the dust in the intermediate frequency furnace body.

[0013] 2. The dust removal hood of the medium frequency furnace uses the limit block, the limit groove and the square groove in coordination. When the dust collection device needs to be replaced or disassembled for maintenance, it is only necessary to rotate the fastening block counterclockwise to disengage the fastening block from the upper end of the slide rod, and then rotate the threaded block counterclockwise to remove the threaded block from the upper end of the slide rod. At this time, the slide rod is pushed to slide through the square plate, so that the limit block slides on the inner wall of the limit groove. When the limit block slides to the top of the square groove, the square plate can be pulled downward to remove the dust collection device for replacement or maintenance, thereby having the advantages of simple disassembly method and high disassembly efficiency.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A dust removal cover for an intermediate frequency furnace comprises an intermediate frequency furnace body 1, a fixed block 2 is fixedly installed on the outer side of the intermediate frequency furnace body 1, an electric telescopic tube 4 is fixedly installed on the top of the fixed block 2, a strip rod 5 is fixedly installed on the extended end of the electric telescopic tube 4, a slide groove 8 is penetrated through the inner wall of the strip rod 5, a limiting groove 9 is provided on the inner wall of the slide groove 8, a limiting block 11 is slidably connected to the inner wall of the limiting groove 9, a sliding rod 10 is fixedly installed on the inner side of the limiting block 11, a threaded block 12 and a fastening block 13 are threadedly connected to the upper end of the sliding rod 10, a square plate 6 and a dust suction device 7 are fixedly installed on the bottom of the sliding rod 10, and a square groove 14 is provided at the bottom of the strip rod 5.

[0022] In the above structure, through the setting of the square groove 14, the square groove 14 and the limit block 11 are slidably connected, and the limit block 11 is slidably connected to the inner wall of the square groove 14. Therefore, when the square plate 6 and the dust suction device 7 need to be removed for replacement or maintenance, the limit block 11 slides downward on the inner wall of the square groove 14, and the slide rod 10 slides downward on the inner wall of the limit groove 9, and then the square plate 6 and the dust suction device 7 can be removed.

[0023] In a preferred embodiment, the upper end of the slide rod 10 is provided with threads, the inner walls of the threaded block 12 and the fastening block 13 are provided with threaded holes, and the threaded block 12 and the fastening block 13 are threadedly connected to the outer edge of the thread provided on the upper end of the slide rod 10 through the threaded holes.

[0024] In the above structure, the threaded connection between the thread and the threaded hole allows the threaded block 12 and the fastening block 13 to threadably fix the slide bar 10 to the inner wall of the strip bar 5, thereby restricting the square plate 6 and the dust collecting device 7.

[0025] In a preferred embodiment, the sliding rod 10 is slidably connected to the inner wall of the limiting groove 9 , the diameter of the threaded block 12 is larger than the diameter of the strip rod 5 , and the diameter of the fastening block 13 is larger than the diameter of the threaded block 12 .

[0026] In the above structure, the diameter of the threaded block 12 is larger than the diameter of the strip rod 5, and the threaded block 12 is threadedly connected to the upper end of the sliding rod 10. When the threaded block 12 is rotated to the top of the strip rod 5, the diameter of the threaded block 12 is larger than the diameter of the strip rod 5, so that the threaded block 12 can vertically fix the sliding rod 10, so that the sliding rod 10, the square plate 6 and the dust suction device 7 will not fall down, and then the fastening block 13 is rotated so that the bottom of the fastening block 13 is fitted with the top of the threaded block 12, and then the threaded block 12 is tightened and limited, so that the threaded block 12 is restricted in place and cannot move left or right.

[0027] In a preferred embodiment, the square groove 14 is located below the limiting groove 9 and passes through the lower half of the strip rod 5 .

[0028] In the above structure, the square groove 14 passes through the lower half of the strip rod 5, so that when the slide bar 10 slides to the position of the square groove 14, it can slide downward smoothly, thereby facilitating the removal of the square plate 6 and the dust collecting device 7.

[0029] In a preferred embodiment: a controller 3 is fixedly mounted on the outer side of the fixed block 2 , and the electric telescopic tube 4 and the dust suction device 7 are both electrically connected to the controller 3 .

[0030] In the above structure, the electric telescopic tube 4 and the dust suction device 7 are electrically connected to the controller 3, so that the controller 3 can control the electric telescopic tube 4 and the dust suction device 7 to start or stop working.

[0031] In a preferred embodiment, the threaded block 12 is slidably connected to the top of the strip rod 5 , and the bottom of the fastening block 13 overlaps the top of the threaded block 12 .

[0032] In the above structure, through the sliding connection between the threaded block 12 and the strip rod 5, when the threaded block 12 is rotated clockwise at the upper end of the slide rod 10, the threaded block 12 comes into contact with the strip rod 5. At this time, the threaded block 12 can drive the slide rod 10, the square plate 6 and the dust suction device 7 to move horizontally to the left and right at the top end of the strip rod 5 without falling. By rotating the fastening block 13 clockwise at the upper end of the slide rod 10, the threaded block 12 can be tightened, thereby restricting the threaded block 12 in place.

[0033] Working principle: When the device needs to be used, the controller 3 can be used to control the electric telescopic tube 4 to work, so that the extended end of the electric telescopic tube 4 drives the bar 5 to move up and down, thereby adjusting the height of the dust collecting device 7. Then, the threaded connection between the threaded block 12 and the threaded hole on the inner wall of the fastening block 13 is used to rotate the threaded block 12 clockwise, so that the threaded block 12 is threaded down at the upper end of the slide rod 10 and fits on the top of the bar 5. At this time, the threaded block 12 can drive the slide rod 10, the square plate 6 and the dust collecting device 7 to move horizontally to the left and right at the top of the bar 5 without falling. Then, the fastening block 13 is rotated clockwise at the upper end of the slide rod 10. Rotation can lead to tightening the threaded block 12, thereby restricting the threaded block 12 in place, causing the dust collection device 7 to be fixed and restricted, so that the dust in the medium frequency furnace body 1 can be stably drawn out and adsorbed. Later, when the dust collection device 7 needs to be replaced or disassembled for maintenance, it is only necessary to rotate the fastening block 13 counterclockwise to disengage the fastening block 13 from the upper end of the slide rod 10, and then rotate the threaded block 12 counterclockwise to remove the threaded block 12 from the upper end of the slide rod 10. At this time, the slide rod 10 is pushed to slide through the square plate 6, so that the limit block 11 slides on the inner wall of the limit groove 9. When the limit block 11 slides to the top of the square groove 14, the square plate 6 can be pulled downward to remove the dust collection device 7 for replacement or maintenance.
