Description

Technical Field

[0001] The present application relates to the technical field of electric furnaces, and in particular to an integrated furnace cover machine. Background Art

[0002] An electric furnace is a heating furnace that converts the electrical energy in the furnace into heat to heat the workpiece. However, when it is heating, it will produce exhaust gas, which will contain a lot of smoke and dust, so the smoke and dust in the exhaust gas need to be filtered.

[0003] Existing electric furnaces discharge exhaust gas through pipes and filter smoke by installing filter plates in the pipes. However, the filter plates are mostly installed in the pipes. When they need to be cleaned or replaced, the pipes and the electric furnace need to be disassembled and then the surface of the filter plates need to be cleaned. It is difficult to clean the filter plates. For this reason, the present application provides an all-in-one furnace cover to improve this problem. Utility Model Content

The furnace cover shell is used to cover the opening of the electric furnace. A filter plate is installed on the mounting plate. The filter plate is located in the cleaning shell. The filter plate is used to cover the entrance of the connecting pipe. When the furnace cover shell releases the cover of the electric furnace opening, the filter plate is exposed outside the cleaning shell.

[0009] The sealing plate is slidably mounted on the cleaning shell and the furnace cover shell. There is a gap between the cleaning shell, the furnace cover shell and the mounting plate. The sealing plate is used to block or release the gap.

[0011] Furthermore, a slide bar is installed on the filter plate, and the slide bar is slidably connected to the bracket. A connecting spring is installed between the filter plate and the bracket, and the connecting spring forces the filter plate to move away from the bracket.

[0012] Furthermore, a receiving hole is provided on the cleaning shell, a hemispherical block is installed in the receiving hole through a resisting spring, and a limiting hole for accommodating the hemispherical block is provided on the sealing plate.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] Embodiment 1

[0028] As Figure 1-Figure 6 As shown, the furnace cover integrated machine proposed in the first embodiment of the present application includes:

[0029] A mounting plate 1, which is used to be connected to the upper surface of the electric furnace. The mounting plate 1 is provided with a through hole 101 for the electric furnace opening to pass through. When in use, the mounting plate 1 is sleeved on the upper surface of the electric furnace through the through hole 101. The mounting plate 1 and the electric furnace can be connected by welding or other means. The electric furnace opening is located on the upper surface of the mounting plate 1 through the through hole 101;

[0030] A fixing frame 102 is installed on the mounting plate 1, and a large air duct 103 is hinged on the fixing frame 102. A hydraulic rod 104 is installed on the mounting plate 1. The telescopic end of the hydraulic rod 104 is slidably hinged with the large air duct 103. When the telescopic end of the hydraulic rod 104 moves, the large air duct 103 rotates on the fixing frame 102. The large air duct 103 is used for air flow to pass through. A small air duct is also installed on the large air duct 103 to extend the exhaust distance. A block is slidably installed at the bottom of the large air duct 103 along its length direction. The telescopic end of the hydraulic rod 104 is hinged with the block, so that when the telescopic end of the hydraulic rod 104 is extended, the large air duct 103 is pushed to rotate and move away from the mounting plate 1. When the telescopic end of the hydraulic rod 104 is retracted, the large air duct 103 is pulled to make it close to the mounting plate 1.

[0031] The cleaning shell 2 is connected with the large air duct 103 through the connecting pipe 201. A furnace cover shell 202 is installed on the cleaning shell 2. The furnace cover shell 202 is used to cover the opening of the electric furnace. The cleaning shell 2, the connecting pipe 201 and the furnace cover shell 202 are fixedly connected by welding or other means, so that when the large air duct 103 rotates, the three can also be driven to rotate together, so that the furnace cover shell 202 blocks or unblocks the opening of the electric furnace, and the opening of the electric furnace is connected with the inside of the furnace cover shell 202. The cleaning shell 2 is connected with the furnace cover shell 202, so that when the electric furnace is in use, the exhaust gas can be discharged into the furnace cover shell 202 through the opening of the electric furnace, and then discharged after passing through the cleaning shell 2, the connecting pipe 201 and the large air duct 103, so that the furnace cover shell 202 not only plays the role of a cover body, but also plays the role of an exhaust gas pipeline, which increases the practicality of the device;

[0032] A filter plate 3 is installed on the mounting plate 1. The filter plate 3 is located in the clean shell 2. The filter plate 3 is used to block the entrance of the connecting pipe 201. When the furnace cover shell 202 releases the cover of the electric furnace opening, the filter plate 3 is exposed to the outside of the clean shell 2. When the exhaust gas is discharged from the clean shell 2 to the connecting pipe 201, the exhaust gas passes through the filter plate 3, and the smoke and dust inside the exhaust gas are blocked and filtered by the filter plate 3, so that the exhaust gas can be discharged.

[0033] When the filter plate 3 needs to be cleaned, the large air duct 103 is pushed by the hydraulic rod 104 to move it away from the mounting plate 1, and the filter plate 3 is exposed while the electric furnace opening is opened, so that the filter plate 3 is convenient to clean, thereby increasing the practicality of the device;

[0034] The sealing plate 4 is slidably mounted on the cleaning shell 2 and the furnace cover shell 202. There is a gap between the cleaning shell 2, the furnace cover shell 202 and the mounting plate 1. The sealing plate 4 is used to block or release the gap. In order to facilitate the rotation of the cleaning shell 2 and the furnace cover shell 202, a gap is set between the two and the mounting plate 1. When in use, the gap is blocked by the sealing plate 4 to reduce the possibility of heat loss when the electric furnace is in use. When the cleaning shell 2 and the furnace cover shell 202 need to be rotated, the sealing plate 4 is slid to release the contact with the upper surface of the mounting plate 1, so that the two can be rotated, thereby increasing the feasibility of the device;

[0035] Compared with the prior art, the mounting plate 1 is connected to the electric furnace, and the furnace cover shell 202 is used as the cover of the electric furnace. The sealing performance of the furnace cover shell 202 is increased by the sealing plate 4, thereby reducing the heat loss in the electric furnace. The furnace cover shell 202 and the cleaning shell 2 can also act as pipes to discharge the exhaust gas. When the exhaust gas passes through the cleaning shell 2, it is filtered by the filter plate 3 and discharged through the large air duct 103. When it is necessary to continue cleaning, the furnace cover shell 202 and the cleaning shell 2 are opened by the hydraulic rod 104 to expose the filter plate 3, which is convenient for cleaning and increases the practicability of the device.

[0036] Embodiment 2

[0037] like Figure 3 and Figure 6 As shown, the second embodiment further discloses the filter plate 3, the cleaning shell 2 and the furnace cover shell 202 on the basis of the first embodiment. In the second embodiment, a bracket 5 is installed on the mounting plate 1, and an elastic iron sheet 6 is installed on the bracket 5. The filter plate 3 is installed on the bracket 5, and the bracket 5 is fixed on the mounting plate 1, so that when the cleaning shell 2 is away from the mounting plate 1, the bracket 5 still stays in the original position;

[0038] An annular plate 7 is installed on the elastic iron sheet 6, an inclined block 8 is installed on the elastic iron sheet 6, and a contact plate 9 is installed in the cleaning shell 2. A contact block 901 for contacting with the inclined block 8 is installed on the contact plate 9. When the contact block 901 contacts with the inclined block 8, the annular plate 7 is forced to collide with the filter plate 3. The annular plate 7 is located on the side of the filter plate 3 facing the furnace cover shell 202. Because it is annular and has a cavity, it will not cause obstruction to the discharge of exhaust gas. When in use, when the cleaning shell 2 is away from the mounting plate 1, the contact block 901 is also driven away from the mounting plate 1, and the bracket 5 and the spring sheet iron sheet 6, annular plate 7 and inclined block 8 located thereon are not moved, so that the contact plate 9 drives the contact block 901 to approach and contact the inclined block 8, so that the elastic iron sheet 6 is elastically deformed, so that the annular plate 7 knocks the filter plate 3, so that the filter plate 3 is vibrated, so that the smoke and dust attached to it are initially separated from the filter plate 3 through vibration, thereby increasing the practicality of the device;

[0039] Inclined block 8 Figure 6 As shown, when the cleaning shell 2 is reset, the abutment block 901 abuts against the inclined block 8 through the inclined surface on the other side thereof, so that the inclined block 8 avoids the abutment plate 9, so that the abutment plate 9 and the abutment block 901 can be reset smoothly, thereby improving the feasibility of the device.

[0040] As Figure 3 As shown, in the second embodiment, a slide bar 301 is installed on the filter plate 3, and the slide bar 301 is slidably connected with the bracket 5. A connecting spring 302 is installed between the filter plate 3 and the bracket 5, and the connecting spring 302 forces the filter plate 3 to move away from the bracket 5. When in use, the filter plate 3 is resisted by the connecting spring 302, so that when the cleaning shell 2 moves away from the mounting plate 1 and then resets, the filter plate 3 can fit closely with the opening of the connecting pipe 201, thereby reducing the possibility of a large gap between the filter plate 3 and the connecting pipe 201 resulting in a poor filtering effect;

[0041] When the connecting spring 302 pushes the filter plate 3, it is guided by the slide rod 301, which increases the stability of the filter plate 3 when sliding. The connecting spring 302 is sleeved on the outside of the slide rod 301, and the deformation direction of the connecting spring 302 is limited by the slide rod 301, which increases the stability of the connecting spring 302 when deforming.

[0042] like Figure 4 and Figure 5 As shown, in the second embodiment, the cleaning shell 2 is provided with a receiving hole 203, in which a hemispherical block 206 is installed via a resisting spring 205, and the sealing plate 4 is provided with a limiting hole 204 for accommodating the hemispherical block 206. When the hemispherical block 206 is inserted into the limiting hole 204, the sliding of the sealing plate 4 on the cleaning shell 2 is limited, so that Figure 1 From the main perspective, the sealing plate 4 slides in the vertical direction, and the limiting hole 204 is opened at a position of the sealing plate 4 close to its upper part. When the cleaning shell 2 needs to be rotated, the sealing plate 4 is slid upward, and the inner wall of the sealing plate 4 is first guided by the arc surface of the hemispherical block 206 so that the resistance spring 205 is compressed, so that the hemispherical block 206 is retracted into the accommodating hole 203. When the sealing plate 4 slides to the limiting hole 204 and is aligned with the hemispherical block 206, the resistance spring 205 pushes the hemispherical block 206 to be inserted into the limiting hole 204, thereby limiting the sliding of the sealing plate 4, so that when the cleaning shell 2 rotates, the operator does not need to support the sealing plate 4 all the time to prevent it from sliding accidentally, thereby increasing the practicality of the device.

[0043] like Figure 2 , Figure 4 and Figure 5 As shown in the second embodiment, a heat dissipation opening 10 is provided on the furnace cover shell 202, and a baffle 11 for covering the heat dissipation opening 10 is slidably installed on the furnace cover shell 202. Figure 1 From the main perspective, the baffle 11 slides on the furnace cover shell 202 in the vertical direction. When the filter plate 3 needs to be cleaned, the furnace cover shell 202 and the cleaning shell 2 are just opened, and the hot air inside the electric furnace will dissipate through the opening. The temperature is relatively high, and the baffle 11 can be slid in advance to remove the obstruction to the heat dissipation port 10, so that the hot air can be discharged in advance, which reduces the possibility of the hot air affecting the operator's operation and increases the safety of the device.

[0044] Embodiment 3

[0045] like Figure 1-Figure 6As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, an L-shaped plate 12 is installed on the baffle 11, and the free end of the L-shaped plate 12 is connected to the sealing plate 4. Before the cleaning shell 2 needs to be rotated, the sealing plate 4 is slid upward to expose the gap between the cleaning shell 2 and the mounting plate 1 and the gap between the furnace cover shell 202 and the mounting plate 1, thereby accelerating the heat dissipation speed. When the sealing plate 4 slides upward, the baffle 11 is also pulled upward by the L-shaped plate 12 to remove the obstruction of the heat dissipation port 10. The sealing plate 4 and the baffle 11 can be slid together only by sliding the sealing plate 4, thereby increasing the convenience of the device.

[0046] In embodiment three, a guide block 13 is installed on the cleaning shell 2, and a guide groove 14 for accommodating the guide block 13 is provided on the sealing plate 4. The guide groove 14 is opened in the vertical direction, and its inner wall is fitted with the side wall of the guide block 13, so that the sealing plate 4 can only slide in the vertical direction along a straight path, thereby increasing the stability of the sealing plate 4 when sliding.

[0047] In embodiment three, the inclined block 8 is located at one end where the elastic iron sheet 6 is connected to the annular plate 7. When the elastic iron sheet 6 undergoes elastic deformation, the end thereof connected to the bracket 5 serves as a fulcrum, and the inclined block 8 is installed at the end away from the fulcrum, thereby extending the force arm and making the elastic iron sheet 6 act as a force-saving lever, making it easier for the abutment block 901 to deform the elastic iron sheet 6 by abutting against the inclined block 8, thereby increasing the feasibility of the device.

[0048] The above embodiments are merely descriptions for clearly illustrating the present invention, and are not limitations on the implementation methods. For technicians in the relevant field, other different forms of changes or modifications can be made based on the above descriptions. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
