[0021] Specifically, a block may be provided below the sealing cover 2, a groove adapted to the block may be provided on the inner wall of the furnace opening, and a sealing ring may be provided in the groove, so that the sealing cover 2 and the furnace opening are more airtight.

[0022] During operation, the telescopic assembly can lift the sealing cover 2 to facilitate opening the furnace mouth. When the furnace mouth needs to be closed, the telescopic assembly is pressed down to close the furnace mouth, and the first sealing plate 32 and the second sealing plate 33 are slid along the circular slide groove 31 to the top of the sealing cover 2, so that the first sealing plate 32 and the second sealing plate 33 form a covering plate to cover the sealing cover 2. The size of the covering plate is larger than the size of the sealing cover 2, so that the covering plate can close the gap between the sealing cover 2 and the furnace mouth. It should be noted that the lower surfaces of the first sealing plate 32 and the second sealing plate 33 are in contact with the top plate. When the first sealing plate 32 and the second sealing plate 33 are moved to the top of the sealing cover 2, the lower surfaces of the first sealing plate 32 and the second sealing plate 33 are also in contact with the sealing cover 2, so that the airtightness between the covering plate and the sealing cover 2 is good.

[0023] The above structure is set up by setting a telescopic component on the top plate and setting a connecting block 21 to connect the telescopic component with the sealing cover 2, so that the opening and closing of the furnace mouth can be controlled by the telescopic component, and there is no need to open the sealing cover 2 manually, so that the opening of the sealing cover 2 is more convenient. By setting the sealing area 3, the furnace mouth is set in the sealing area 3, and a circular slide groove 31 is set on the outer periphery of the sealing area 3, and a first sealing plate 32 and a second sealing plate 33 slidingly connected to the circular slide groove 31 are set, so that the first sealing plate 32 and the second sealing plate 33 can move in the sealing area 3 and can slide to the top of the sealing plate. The size of the covering plate composed of the first sealing plate 32 and the second sealing plate 33 is set to be larger than the size of the sealing cover 2, so that the first sealing plate 32 and the second sealing plate 33 can completely cover the top of the sealing cover 2 to close the gap between the sealing cover 2 and the furnace mouth, thereby ensuring the sealing effect.

[0024] In this embodiment, Figure 1As shown, the telescopic assembly includes a first bracket 4 fixedly connected to the top plate, the first bracket 4 is L-shaped, and a hydraulic cylinder 41 is fixedly connected to the bracket corresponding to the furnace mouth, and the output end of the hydraulic cylinder 41 is fixedly connected to the connecting block 21.

[0025] The above structure is set up by setting a hydraulic cylinder 41 on the top plate, and connecting the output end of the hydraulic cylinder 41 to the sealing cover 2 through the connecting block 21, so that the hydraulic cylinder 41 can drive the sealing cover 2 to move up and down, which is used to control the opening and closing of the furnace mouth. The setting of the hydraulic cylinder 41 makes the opening and closing of the sealing cover 2 more convenient.

[0026] In this embodiment, Figure 2 As shown, a second bracket 5 is fixedly connected to the top plate, and the second bracket 5 includes a first connecting plate fixedly connected to the top plate and a second connecting plate fixedly connected to the first connecting plate. A threaded hole is provided on the second connecting plate, and a screw 51 is threadedly connected in the threaded hole. An end of the screw 51 close to the top plate is fixedly connected to a pressure plate 53, and an end of the screw 51 away from the pressure plate 53 is fixedly connected to a knob 52.

[0027] It should be noted that the length direction of the screw rod 51 is perpendicular to the top plate, and the lower surface of the pressing plate 53 is parallel to the top plate.

[0028] During operation, when the first sealing plate 32 and the second sealing plate 33 cover the sealing cover 2, the adjacent sides of the first sealing plate 32 and the second sealing plate 33 are in contact with each other, and a portion of the first sealing plate 32 and the second sealing plate 33 are located under the pressure plate 53. At this time, the screw 51 is turned to make the pressure plate 53 press the first sealing plate 32 and the second sealing plate 33 under the pressure plate 53 downward to position the first sealing plate 32 and the second sealing plate 33.

[0029] The above structure is arranged by arranging a second bracket 5 on the top plate, and threading a screw 51 on the second bracket 5, and connecting a pressure plate 53 below the screw 51, so that when the screw 51 moves downward, the pressure plate 53 can press the first sealing plate 32 and the second sealing plate 33 into position, thereby ensuring that the first sealing plate 32 and the second sealing plate 33 cover and seal the sealing cover 2.

[0030] In this embodiment, Figure 1 and Figure 4 As shown, both the first sealing plate 32 and the second sealing plate 33 are provided with anti-scalding handles 6 .

[0031] Specifically, the anti-scalding handle 6 can be a wooden handle.

[0034] The above structure is set up by setting a limit groove 311 on one side of the circular slide groove 31, and setting a limit block 321 adapted to the limit groove 311 on the first sealing plate 32 and the second sealing plate 33, so that the first sealing plate 32 and the second sealing plate 33 will not be separated from the top plate during the sliding process along the circular slide groove 31, and the distance between the lower surface of the first sealing plate 32 and the second sealing plate 33 and the top plate will not change, thereby ensuring the sealing effect of the first sealing plate 32 and the second sealing plate 33 on the sealing cover 2.

[0035] In this embodiment, Figure 1 and Figure 4 As shown, the first sealing plate 32 and the second sealing plate 33 are respectively provided with a first groove 322 and a second groove, and the first groove 322 and the second groove together form a clearance groove adapted to the connection block 21 .

[0036] Specifically, the first sealing plate 32 and the second sealing plate 33 are both arranged in a fan shape, and the angle of the fan shape can be set to ninety degrees. When the first sealing plate 32 and the second sealing plate 33 are combined to form a covering plate, the covering plate occupies half the size of the sealing area 3, and the size of the sealing cover 2 is set to be smaller than half the size of the sealing area 3. Then, the covering plate can completely cover the gap between the sealing cover 2 and the furnace mouth, and a clearance groove is set so that when the first sealing plate 32 and the second sealing plate 33 cover the sealing cover 2, they will not be affected by the connecting block 21 fixedly connected to the sealing cover 2.
