Description

Technical Field

[0001] This utility model relates to the field of induction furnace technology, and in particular to a dust collector for medium-frequency induction furnaces. Background Technology

[0002] When smelting metal in a medium-frequency induction furnace, if the material is added from the furnace opening, a lot of flue gas and dust will be generated, including harmful substances such as metal oxides and dust particles. Therefore, for environmental protection and the health of workers, the flue gas and dust generated must be collected by a dust collector.

[0003] Existing dust collectors mostly use fans to adsorb and clean flue gas and dust. However, the fan and the medium-frequency induction furnace are fixedly connected, so the adsorption direction of the fan is also constant. It is impossible to quickly adjust the angle of the fan to match the adsorption direction according to the direction of flue gas and dust dispersion, which results in a large limitation of the dust removal function of the fan. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: most existing dust collectors use fans to adsorb and clean flue gas and dust. However, the fan and the medium-frequency induction furnace are fixedly connected, so the adsorption direction of the fan is also constant. It is impossible to quickly adjust the angle of the fan to match the adsorption direction according to the dispersion direction of flue gas and dust, which results in a large limitation of the dust removal function of the fan. Therefore, this invention proposes a dust collector for medium-frequency induction furnaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust collector for a medium-frequency induction furnace includes a furnace body. A feeding pipe is provided at the top of the furnace body, and a furnace cover is rotatably installed at the top of the feeding pipe. Mounting plates are fixedly installed on the left and right side walls of the furnace body. Arc-shaped mounting rods are fixedly installed on the upper surface of the two mounting plates. Arc-shaped sliding openings are formed on the surface of the mounting rods. Arc-shaped sliding rods are fixedly installed in the sliding openings. A slider is slidably sleeved on the sliding rods. Mounting plates are fixedly installed on the surface of the sliders. Mounting openings are formed on the surface of the mounting plates. A fan is fixedly installed in the mounting openings. A fume hood for covering the mounting openings is fixedly installed on the surface of the mounting plates away from the feeding pipes.

[0007] A straight rod is vertically fixed on the upper surface of the mounting plate, and a sliding plate is slidably sleeved on the straight rod. An insert rod is vertically fixed on the lower surface of the sliding plate. The surface of the mounting rod has multiple circumferentially shaped insertion holes that are connected to the sliding opening and used for inserting the end of the insert rod. The sliding plate is connected to the mounting plate through a telescopic component.

[0008] Preferably, a space is reserved between the surface of the mounting plate near the feeding pipe and the top of the feeding pipe for rotating and opening the furnace cover.

[0009] Preferably, a filter plate is fixedly installed on the wall of the installation port away from the smoke hood, and the filter plate is used to filter large particulate impurities in the flue gas.

[0010] Preferably, the upper surface of the mounting plate is provided with a limiting component, which is used to limit the movement of the slide plate away from the mounting plate.

[0011] Preferably, the limiting component includes an L-shaped limiting rod and a rubber sleeve rotatably fitted onto the limiting rod. The upper surface of the mounting plate is provided with a mounting groove. One end of the limiting rod is rotatably installed in the mounting groove, and the surface of the rubber sleeve is fixedly connected to the groove wall.

[0012] Preferably, the telescopic component includes a telescopic spring sleeved on a straight rod, with both ends of the telescopic spring fixedly connected to a mounting plate and a sliding plate, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By coordinating the mounting rod, sliding rod, slider, mounting plate, insertion rod, and multiple insertion ports, the angle of the fan can be quickly adjusted according to the direction of the flue gas and dust generated during feeding, so that the adsorption direction of the fan matches the direction of the flue gas and dust, thus improving the applicability of the fan for dust removal.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-5 A dust collector for a medium-frequency induction furnace includes a furnace body 1. A feeding pipe 2 is provided at the top of the furnace body 1. A furnace cover 3 is rotatably installed at the top of the feeding pipe 2. Mounting plates are fixedly installed on the left and right side walls of the furnace body 1. Arc-shaped mounting rods 4 are fixedly installed on the upper surface of the two mounting plates. Arc-shaped sliding openings 5 ​​are opened on the surface of the mounting rods 4. Arc-shaped sliding rods 6 are fixedly installed in the sliding openings 5. A slider 7 is slidably sleeved on the sliding rods 6. Mounting plate 8 is fixedly installed on the surface of the slider 7. An installation opening is opened on the surface of the mounting plate 8. A fan 9 is fixedly installed in the installation opening. A smoke hood 10 for covering the installation opening is fixedly installed on the surface of the mounting plate 8 away from the feeding pipe 2. A space is reserved between the surface of the mounting plate 8 near the feeding pipe 2 and the top of the feeding pipe 2 for rotating and opening the furnace cover 3.

[0024] A straight rod 11 is vertically fixedly installed on the upper surface of the mounting plate 8. A sliding plate 12 is slidably sleeved on the straight rod 11. An insert rod 13 is vertically fixedly installed on the lower surface of the sliding plate 12. The surface of the mounting rod 4 has multiple circumferentially formed insertion ports 14 that are connected to the sliding ports 5 and are used for inserting the ends of the insert rods 13. The sliding plate 12 is connected to the mounting plate 8 through a telescopic component. The telescopic component includes a telescopic spring 15 sleeved on the straight rod 11. The two ends of the telescopic spring 15 are fixedly connected to the mounting plate 8 and the sliding plate 12, respectively.

[0025] When the furnace cover 3 is rotated to open the top opening of the feeding pipe 2, the feeding operation can be carried out. During the operation, smoke and dust will be generated. At this time, the operator can control the sliding plate 12 to move the insert rod 13 upward according to the direction of smoke and dust dispersion. The extension spring 15 will be stretched until the insert rod 13 is removed from the insertion port 14. Then the fixation of the slider 7 can be released, and the slider 7 can be controlled to slide along the sliding port 5 with the mounting plate 8 until the mounting port on the surface of the mounting plate 8 is aligned with the direction of smoke and dust dispersion. After the positions are basically aligned, the position of the slider 7 in the sliding opening 5 is finely adjusted until the insertion rod 13 moves to the position corresponding to the insertion opening 14 closest to itself. Then, the slide plate 12 is released, and the slide plate 12 will move and reset quickly with the insertion rod 13 under the elastic potential energy of the extension spring 15. The end of the insertion rod 13 will then be inserted into the insertion opening 14 corresponding to its own position, thereby completing the fixation of the mounting plate 8. Then, the fan 9 is started to draw the upward-blown smoke and dust into the smoke hood 10.

[0026] A filter plate 16 is fixedly installed on the wall of the installation port away from the smoke hood 10. The filter plate 16 is used to filter large particulate impurities in the flue gas.

[0027] The upper surface of the mounting plate 8 is provided with a limiting component, which is used to limit the movement of the slide plate 12 away from the mounting plate 8. The limiting component includes an L-shaped limiting rod 17 and a rubber sleeve 18 that is rotatably sleeved on the limiting rod 17. The upper surface of the mounting plate 8 is provided with a mounting groove, one end of the limiting rod 17 is rotatably installed in the mounting groove, and the surface of the rubber sleeve 18 is fixedly connected to the groove wall.

[0028] The rubber sleeve 18 has good elasticity and adhesion, resulting in a large frictional force between the rubber sleeve 18 and the contact surface of the limiting rod 17. This prevents the limiting rod 17 from rotating. When the mounting plate 8 is moved to the appropriate position and fixed, the limiting rod 17 can be manually rotated so that the top of the limiting rod 17 is above the slide plate 12 and abuts against the slide plate 12. At this time, due to the restriction of the limiting rod 17, the slide plate 12 will not move upward, thus preventing the slide plate 12 from moving due to the influence of external vibration force, which would cause the insertion rod 13 to move out of the insertion port 14.

[0029] When it is necessary to remove the restriction on the skateboard 12, simply rotate the restriction bar 17 so that it is no longer above the skateboard 12 and no longer in contact with the skateboard 12, which is convenient and quick.

[0030] In this invention, when the furnace cover 3 is rotated to open the top opening of the feeding pipe 2, feeding can be performed. During the operation, smoke and dust will be generated. At this time, the operator can control the sliding plate 12 to move the insert rod 13 upward according to the direction of smoke and dust dispersion. The telescopic component will be stretched until the end of the insert rod 13 is removed from the insertion port 14. Then, the fixation of the slider 7 can be released. Then, the slider 7 is controlled to slide along the sliding port 5 with the mounting plate 8 until the mounting port on the surface of the mounting plate 8 is basically aligned with the direction of smoke and dust dispersion. At this time, the position of the slider 7 in the sliding port 5 is finely adjusted until... After the insertion rod 13 moves to the position corresponding to the nearest insertion port 14, the sliding plate 12 is released. The sliding plate 12 will then move and reset quickly with the insertion rod 13 under the elastic potential energy of the telescopic component. The end of the insertion rod 13 will then be inserted into the insertion port 14 corresponding to its own position, thereby completing the fixation of the mounting plate 8. Then, the fan 9 is started, so that the upward-drifting smoke and dust are sucked into the fume hood 10. The angle of the fan 9 can be quickly adjusted according to the drift direction of the smoke and dust generated during feeding, so that the adsorption direction of the fan 9 is adapted to the drift direction of the smoke and dust, thus improving the dust removal applicability of the fan 9.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
