Description

Technical Field

[0001] This utility model belongs to the field of melting furnace technology, and specifically relates to a sealing plate for reducing heat loss from melting furnaces. Background Technology

[0002] A melting furnace is an industrial device used to heat solid substances to above their melting point, transforming them into a liquid state. It is widely used in metallurgy, casting, chemical industry, waste treatment and other fields. In a melting furnace, the sealing plate (also known as a heat insulation baffle or sealing plate) is a key component to reduce heat loss and improve thermal efficiency, and is especially suitable for openings that are prone to heat dissipation, such as furnace doors, feeding ports, and slag discharge ports.

[0003] Existing sealing plates used to reduce heat loss from melting furnaces operate by automatically opening and closing hydraulically. They utilize heat-resistant steel as the frame or shell to withstand mechanical stress and refractory insulation materials to reduce heat loss. However, in actual use, the furnace opening needs constant opening and closing. This repetitive operation causes the hydraulic rod seals (such as O-rings and dust rings) to wear down over time, leading to leaks. Impurities may become embedded in the seals or directly contact the hydraulic rod surface, causing scratches or wear, reducing sealing effectiveness and increasing friction. This can affect the accuracy of the hydraulic rod's movement, potentially leaving gaps when controlling the furnace opening seal, resulting in heat loss. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a sealing plate for reducing heat loss from a melting furnace. The sealing plate can be moved quickly and stably towards or away from the sealing seat by a rotating arm, thereby achieving stable sealing or rapid opening of the melting furnace opening and effectively preventing heat loss.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a sealing plate for reducing heat loss from a melting furnace, including a sealing seat, with multiple rotating shafts rotatably arranged inside the sealing seat, and a drive arm provided at the end of each rotating shaft away from the sealing seat. The end of each drive arm on the same side away from the rotating shaft is rotatably connected to a sealing plate body. Rotating arms are fixedly sleeved on the outer arc surface of the rotating shaft near the vertical center of the sealing seat. Symmetrically distributed bidirectional lead screws are rotatably arranged inside the sealing seat, and symmetrically distributed drive seats are threaded to the outer arc surface of the bidirectional lead screws. Symmetrically distributed linkage slides are rotatably arranged on each drive seat, and symmetrically distributed drive grooves are opened on each rotating arm. The linkage slides are respectively installed in conjunction with adjacent drive grooves. A refractory ceramic fiber coating is provided on the outer side of both the sealing seat and the sealing plate body.

[0006] As a further improvement of this utility model, the sealing seat is also provided with a driving mechanism, which is used to drive the movement of the sealing plate. The driving mechanism includes a bevel gear one fixedly sleeved on the outer arc surface of the bidirectional lead screw. The sealing seat is rotatably provided with symmetrically distributed rotating rods. The end of each rotating rod near the bevel gear one is fixedly sleeved with a bevel gear two. The bevel gear two is respectively meshed with the adjacent bevel gear one. The sealing seat is provided with a dual-shaft motor. The output shaft of the dual-shaft motor is fixed to the adjacent rotating rods through couplings.

[0007] As a further improvement of this utility model, an aluminum silicate fiber board 1 is provided in the middle of the sealing seat, an aerogel felt 1 is provided between the aluminum silicate fiber board 1 and the inner wall of the sealing seat, an aluminum silicate fiber board 2 is provided inside the sealing plate body, and an aerogel felt 2 is provided between the aluminum silicate fiber board 2 and the inner wall of the sealing plate body.

[0008] As a further improvement of this utility model, a control box is provided inside the sealing seat, and the dual-axis motor is electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the insulation performance of the side near the melting furnace opening is increased by the aluminum silicate fiber board 1 installed inside the sealing seat and the aluminum silicate fiber board 2 installed inside the sealing plate, thus preventing the heat inside the melting furnace opening from easily dissipating.

[0011] Secondly, the insulation layer is further increased by filling the aerogel felt one between the aluminum silicate fiberboard one and the sealing plate body and the aerogel felt two between the sealing plate body and the aluminum silicate fiberboard two.

[0012] Third, the dual-axis motor is controlled by the control box, so that the output shaft of the dual-axis motor drives the rotating rod connected to it to rotate. The rotating shaft, the drive arm and the sealing plate can form a parallelogram, so that the rotating shaft on both sides drives the sealing plate to move closer to the sealing seat or move away from the sealing seat at the same time through the rotating arm, thereby sealing or opening the melting furnace opening.

[0013] Fourth, the refractory ceramic fiber coating on the outside of the sealing seat and sealing plate can increase the protection of the outside of the sealing seat and sealing plate, effectively increasing the service life. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 3 As shown, the device includes a sealing seat 101. Multiple rotating shafts 102 are rotatably mounted inside the sealing seat 101. A drive arm 103 is mounted at the end of each rotating shaft 102 away from the sealing seat 101. The end of each drive arm 103 on the same side away from the rotating shaft 102 is rotatably connected to a sealing plate 104. Rotating arms 201 are fixedly sleeved on the outer arc surface of each rotating shaft 102 near the vertical center of the sealing seat 101. Symmetrically distributed bidirectional lead screws 204 are rotatably mounted inside the sealing seat 101. Symmetrically distributed drive seats 202 are threaded onto the outer arc surface of each bidirectional lead screw 204. Symmetrically distributed linkage slide columns 203 are rotatably mounted on each drive seat 202. Symmetrically distributed drive grooves are formed on each rotating arm 201. The linkage slide columns 203 are respectively fitted into adjacent drive grooves. A drive mechanism is also provided on the sealing seat 101 to drive the movement of the sealing plate 104.

[0022] like Figure 2 , 3As shown, the driving mechanism includes a bevel gear 205 fixedly sleeved on the outer arc surface of the bidirectional lead screw 204. The sealing seat 101 is rotatably provided with symmetrically distributed rotating rods 206. Each rotating rod 206 near the end of the bevel gear 205 is fixedly sleeved with a bevel gear 207. The bevel gear 207 is meshed with the adjacent bevel gear 205. The sealing seat 101 is provided with a dual-axis motor 208. The output shaft of the dual-axis motor 208 is fixed to the adjacent rotating rods 206 by couplings.

[0023] like Figure 2 , 4 As shown, an aluminum silicate fiberboard 105 is provided in the middle of the sealing seat 101, an aerogel felt 106 is provided between the aluminum silicate fiberboard 105 and the inner wall of the sealing seat 101, an aluminum silicate fiberboard 107 is provided inside the sealing plate 104, and an aerogel felt 108 is provided between the aluminum silicate fiberboard 107 and the inner wall of the sealing plate 104.

[0024] like Figure 2 As shown, a control box 301 is installed inside the sealing seat 101, and a dual-axis motor 208 is electrically connected to the control box 301.

[0025] In operation, the control box 301 regulates the operation of the dual-axis motor 208, causing the output shaft of the dual-axis motor 208 to drive the rotating rod 206 connected to it to rotate. The rotating rod 206 then drives the bevel gear 207 mounted on it to rotate. Through the meshing relationship between the bevel gear 207 and the first bevel gear 205, the double-acting lead screw 204 containing the first bevel gear 205 rotates. Through the threaded relationship between the double-acting lead screw 204 and the drive seat 202, the two drive seats 202 on both sides move towards each other or away from each other. During the movement of the drive seats 202... During the process: the drive seat 202 drives the linkage slide column 203 to move in the drive groove, which in turn causes the drive seat 202 to drive the rotating arm 201 where the drive groove is located to rotate through the cooperation of the linkage slide column 203 and the drive groove. This causes the rotating arm 201 to drive the rotating shaft 102 to rotate. The rotating shaft 102, the drive arm 103 and the sealing plate 104 can form a parallelogram, so that the rotating shafts 102 on both sides drive the sealing plate 104 to move closer to the sealing seat 101 or move away from the sealing seat 101 simultaneously through the rotating arm 201, thereby sealing or opening the melting furnace opening.

[0026] When sealing the furnace opening with the sealing plates 104 on both sides, the aluminum silicate fiber board 105 inside the sealing seat 101 and the aluminum silicate fiber board 107 inside the sealing plate 104 increase the heat insulation performance on the side near the furnace opening, preventing the heat inside the furnace opening from easily dissipating. The aerogel felt 106 between the aluminum silicate fiber board 105 and the sealing plate 104 and the aerogel felt 108 between the sealing plate 104 and the aluminum silicate fiber board 107 further increase the heat insulation layer. The combination of aluminum silicate fiber board 105, aluminum silicate fiber board 107, aerogel felt 106 and aerogel felt 108 can effectively increase the overall heat resistance and provide efficient sealing and heat insulation for the furnace opening, effectively preventing heat loss.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, both the sealing seat 101 and the sealing plate 104 have a refractory ceramic fiber coating on their outer sides. During use, the refractory ceramic fiber coating on the outer sides of the sealing seat 101 and the sealing plate 104 increases the protection for their outer sides, effectively extending their service life.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
