Description

Technical Field

[0001] This utility model relates to the field of medium frequency furnaces, and in particular to a medium frequency furnace cover with integrated smelting dust collection. Background Technology

[0002] Induction furnaces are widely used smelting equipment in the casting and metallurgical industries. During the smelting process, especially in the feeding, melting, and refining stages, a large amount of high-temperature fumes are generated. These fumes contain harmful substances, and direct emission of them will seriously pollute the environment and endanger the health of operators.

[0003] Currently, the common approach is to install an independent fume hood above the induction furnace, connected to the dust removal system via external pipes. However, this traditional external fume hood has the following drawbacks: low fume collection efficiency, easy escape of smoke and dust, and its relatively fixed structure makes it difficult to adjust the size of the fume collection opening according to actual needs, thus making it impractical. Therefore, a furnace cover for an induction furnace with integrated smelting dust collection is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated smelting fume collection medium-frequency furnace cover, which aims to improve the following disadvantages of the existing traditional external fume hood: low fume collection efficiency, easy fume dispersion, and the inability to adjust the size of the fume collection port according to actual needs due to its relatively fixed structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a medium-frequency furnace cover for integrated smelting dust collection, comprising an outer shell, a side shell fixedly connected to the bottom of the outer shell, a bottom shell fixedly connected to the bottom of the side shell, a dust collection assembly installed in the middle of the outer shell, multiple auxiliary smoke collection ports opened in the upper part of the side shell, the dust collection assembly comprising a smoke collection hopper, the smoke collection hopper being fixedly connected to the bottom shell, a smoke guide hopper provided in the middle of the smoke collection hopper, an adjusting bolt rotatably connected through the middle of the smoke guide hopper, a connecting cylinder threadedly connected to the upper part of the adjusting bolt, the connecting cylinder being fixedly connected to the inner wall of the outer shell, an auxiliary rod movably connected through the smoke guide hopper, and a limit cap threadedly connected to the lower part of the auxiliary rod.

[0006] As a further description of the above technical solution:

[0007] A limiting piece is fixedly connected to the middle of the adjusting bolt, and the limiting piece abuts against the lower part of the inner wall of the flue.

[0008] As a further description of the above technical solution:

[0009] An auxiliary cover is fixedly connected to the front side of the side shell.

[0010] As a further description of the above technical solution:

[0011] The bottom of the bottom shell is fixedly connected with multiple anchors, and the anchors are inverted V-shaped.

[0012] As a further description of the above technical solution:

[0013] The bottom shell is fixed with a casting layer, the anchor is fixed in the casting layer, and a fire-resistant sealing layer is fixedly connected to the bottom of the casting layer.

[0014] As a further description of the above technical solution:

[0015] A connecting pipe is fixedly connected through the rear left side of the outer casing.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by setting up the cooperation between the outer shell, side shell, bottom shell, and smoke collection components, and by opening an auxiliary smoke collection port on the side shell, the smoke collection efficiency can be improved and the emission of smoke can be reduced. By cooperating between the smoke collection hopper, the smoke guide hopper, the adjusting plug, the connecting cylinder, the auxiliary rod, and other components, the size of the smoke collection port can be adjusted, making it more practical.

[0018] 2. In this utility model, the sealing and fire resistance of the furnace cover can be improved by setting a fire-resistant sealing layer. A good seal can reduce heat loss in the furnace when the furnace cover is on, which is conducive to energy saving. Improving the fire resistance of the furnace cover can better protect the furnace cover and extend its service life. Furthermore, by setting the connection between the anchor and the casting layer, the stability of the fire-resistant sealing layer can be improved, making it more practical.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an integrated smelting dust collection medium-frequency furnace cover, comprising an outer shell 1 for connecting various components. A connecting pipe 11 is fixedly connected through and to the rear left side of the outer shell 1 for installing the medium-frequency furnace cover and for conveying the collected dust. The medium-frequency furnace cover is connected to a cyclone separator. A side shell 2 is fixedly connected to the bottom of the outer shell 1 for connecting the outer shell 1 and the bottom shell 3. The bottom of the side shell 2 is fixedly connected to the bottom shell 3. A dust collection assembly 6 is installed in the middle of the outer shell 1 for dust collection. Multiple auxiliary dust collection ports 21 are provided on the upper part of the side shell 2 for collecting the emitted dust. An auxiliary cover 22 is fixedly connected to the front of the side shell 2 for shielding the discharge port of the medium-frequency furnace.

[0027] Furthermore, the smoke collection assembly 6 includes a smoke collection hopper 61, which is used to collect smoke. The hopper is bucket-shaped and fixedly connected to the bottom shell 3. A guide hopper 62 is provided in the middle of the smoke collection hopper 61, with a gap between it and the smoke collection hopper 61 to form a smoke collection opening. An adjusting bolt 63 is rotatably connected through the middle of the guide hopper 62, used to adjust the height of the guide hopper 62 to adjust the size of the smoke collection opening. A connecting cylinder 64 is threadedly connected to the upper part of the adjusting bolt 63. The connecting tube 64 is fixedly connected to the inner wall of the outer shell 1. An auxiliary rod 65 is movably connected through the smoke guide 62 to assist in the stability of the smoke guide 62 during installation. A limit cap 651 is threadedly connected to the lower part of the auxiliary rod 65 for limiting. A limit piece 631 is fixedly connected to the middle part of the adjusting bolt 63 for limiting the smoke guide 62, so as to cooperate with the adjusting bolt 63 to drive the smoke guide 62. The limit piece 631 abuts against the lower part of the inner wall of the smoke guide 62.

[0028] like Figure 4 As shown, the bottom of the bottom shell 3 is fixedly connected with multiple anchors 31, which are inverted V-shaped. The bottom of the bottom shell 3 is fixed with a casting layer 4, which is used to ensure the stability of the connection between the bottom shell 3 and the casting layer 4. It is a high-alumina or clay-based castable and is used to help the bottom shell 3 and the refractory sealing layer 5 to be integrally formed. The anchors 31 are fixed in the casting layer 4. The bottom of the casting layer 4 is fixedly connected with the refractory sealing layer 5, which can be produced by refractory castable.

[0029] Working principle: When in use, first install the furnace cover on the medium-frequency furnace through the connecting pipe 11. Then, when the medium-frequency furnace is in use, turn on the cyclone separator. The cyclone separator will create a negative pressure inside the furnace cover, so that the generated smoke and dust can enter the outer shell 1 through the smoke collection port between the smoke collection hopper 61 and the smoke guide hopper 62. Some smoke and dust that cannot be collected in time will float upwards and be sucked into the outer shell 1 through the auxiliary smoke collection port 21. The collected smoke and dust will be sent into the cyclone separator through the connecting pipe 11 and the connecting component connected to the cyclone separator, thereby completing the collection and treatment of smoke and dust.

[0030] When it is necessary to adjust the size of the smoke collection port, first loosen the multiple limit caps 651, and then rotate the adjusting bolt 63. Depending on the rotation direction of the adjusting bolt 63, the adjusting bolt 63 will move up or down along the connecting cylinder 64. Thus, the adjusting bolt 63 can drive the smoke guide 62 connected to it to move up or down, thereby adjusting the size of the gap between the smoke collection hopper 61 and the smoke guide hopper 62, and thus adjusting the size of the smoke collection port to meet different smoke and dust collection needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
