It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0027] Embodiment 1:

[0028] like Figures 1 to 7As shown, an in-furnace air conveying device of this embodiment includes a conveying mechanism 1, an air inlet mechanism Ⅰ2 and an exhaust mechanism Ⅰ3; the conveying mechanism 1 includes a conveying box 106, and a push plate 107 is provided in the conveying box 106 to divide the inner cavity of the conveying box 106, and the push plate 107 is slidably and sealedly matched with the conveying box 106 to form a working cavity on the right side of the conveying box 106, and the push plate 107 is connected to a driving mechanism for driving it to reciprocate along the conveying box 106.

[0029] In this embodiment, the driving mechanism adopts the following structure. Specifically, a fixed plate 101 is fixedly connected to the left side of the conveying box 106, a motor base 102 is fixedly connected to the left side of the top of the fixed plate 101, a motor 103 is fixedly connected to the top of the motor base 102, and an air supply rotating rod 104 is fixedly connected to the output shaft of the motor 103; an air supply rod 105 is fixedly connected to the left side of the push plate 107, the air supply rod 105 is slidably arranged on the left side of the conveying box 106 and penetrates the side wall of the conveying box 106, and a waist-shaped groove that cooperates with the air supply rotating rod 104 is fixedly connected to the left side of the air supply rod 105, and the air supply rotating rod 104 is slidably arranged in the waist-shaped groove. When the motor 103 rotates, the air supply rotating rod 104 cooperates with the waist-shaped groove to drive the air supply rod 105 to move left and right, thereby driving the push plate 107 to reciprocate left and right.

[0030] The air inlet mechanism I2 is arranged on the right side of the conveying box 106, and includes a support plate 1 201 and a sealing plate 2 203. A slot is arranged at the lower end of the right side of the conveying box 106, and the support plate 1 201 is fixedly arranged in the slot. A gap is arranged between the support plate 1 201 and the slot to facilitate gas entry. The sealing plate 203 is arranged on the upper end of the support plate 1 201 through the spring 202; when the right side of the conveying box 106 is under positive pressure, the sealing plate 203 moves downward under the action of the spring 202, and the sealing plate 203 and the slot are slidably sealed; when the right side of the conveying box 106 is under negative pressure, the sealing plate 203 overcomes the pulling force of the spring 202 and moves upward to facilitate gas entry.

[0031] The bottom of the sealing plate 203 is fixedly connected with a limiting slide block 204 , and the bottom of the inner wall of the conveying box 106 is provided with a limiting slide groove 205 , and the limiting slide block 204 is slidably connected in the limiting slide groove 205 .

[0032] The exhaust mechanism I3 includes a sealing plate 303 and a fixing rod 301. An opening is provided on the right side of the conveying box 106. A plurality of fixing rods 301 are provided and fixedly provided on the conveying box 106. The sealing plate 303 is connected to the fixing rod 301 through a plurality of springs 302. When the right side of the conveying box 106 is under negative pressure, the sealing plate 303 moves to the left under the action of the spring 302, and the sealing plate 303 seals with the opening; when the right side of the conveying box 106 is under positive pressure, the sealing plate 303 overcomes the pulling force of the spring 302 and moves to the right, facilitating the discharge of gas.

[0033] In order to ensure the movement trajectory of the sealing plate 303, a plurality of limit sliders 304 are fixedly connected to the left side of the sealing plate 303, and a slide groove 305 is opened on the inner wall of the conveying box 106, and the outer wall of the limit slider 304 is slidably connected in the slide groove 305.

[0034] The implementation principle of the air delivery device in the furnace in the embodiment of the present application is as follows: when it is necessary to supply air to the furnace, the motor 103 is operated to drive the air supply rod 105 to reciprocate. When the air supply rod 105 moves to the right, the air supply rod 105 pushes the push plate 107, and the push plate 107 delivers the air inside the delivery box 106 to the direction of the sealing plate 303, so that the air inside the delivery box 106 is compressed, and then the sealing plate 303 is pushed outward, and at the same time, the sealing plate 303 drives the limit slider 303. 04 moves outward along the slide groove 305, and then the air inside the conveying box 106 enters the furnace along the edge of the sealing plate 303. When the air supply rod 105 moves back, the sealing plate 303 is subjected to the internal negative pressure and the force of the spring 302, and the sealing plate 303 drives the limiting slider 304 to move along the slide groove 305 toward the inside of the conveying box 106, thereby closing the space inside the furnace, effectively preventing the fire in the furnace from entering the inside of the conveying box 106 due to excessive fire, and preventing accidents.

[0035] When the air supply rod 105 drives the push plate 107 to move to the left along the inside of the conveying box 106, the negative pressure inside the right side of the conveying box 106 causes the sealing plate 203 to drive the limiting slider 204 and the spring 202 to move upward along the limiting slide groove 205, so that the external air enters the inside of the conveying box 106 along the bottom gap, thereby conveying air to the inside of the conveying box 106, which is convenient for the next step of air conveying. When the air supply rod 105 moves to the right, the sealing plate 203 loses the negative pressure inside the conveying box 106, so that the negative pressure becomes pressurized, so that the sealing plate 203 moves downward under the force of the spring 202, so that the slot is closed, and the air inside the conveying box 106 is prevented from being discharged through the slot.

[0036] Embodiment 2:

[0037] In this embodiment, based on the first embodiment, the conveying box 106 on the left side of the push plate 107 is also configured as a sealed cavity, and an air inlet mechanism II4 and an air exhaust mechanism II5 are provided in the sealed cavity on the left side; the structure of the air inlet mechanism II4 is the same as that of the air inlet mechanism I2.

[0038] Specifically, it includes a support plate 401 and a sealing plate 403. A slot is set at the lower left end of the conveying box 106. The support plate 401 is fixed in the slot. A gap is set between the support plate 401 and the slot. The sealing plate 403 is set at the upper end of the support plate 401 through a spring 402. When the sealing plate 403 moves downward under the action of the spring 402, the sealing plate 403 and the slot are slidably sealed.

[0039] The bottom of the sealing plate 403 is fixedly connected to a limiting slide block 404 , and the bottom of the inner wall of the conveying box 106 is provided with a limiting slide groove 506 , and the limiting slide block 404 is slidably connected in the limiting slide groove 506 .

[0040] The exhaust mechanism II5 includes a sealing sheet 501, and an air outlet 502 is provided on the inner wall of the conveying box 106. The left side of the air outlet 502 is connected to the outer end surface of the sealing plate 1 303 through the air supply pipeline 6. A fixing block 503 is fixedly connected to the right side of the inner wall of the air outlet 502, and a spring 4 504 is fixedly connected to the left side of the fixing block 503. The sealing sheet 501 is connected to the fixing block 503 through the spring 4 504. When the sealing sheet 501 moves to the right, the sealing sheet 501 is sealed and connected to the air outlet 502, and a limit stopper 505 is fixedly connected to the left side of the inner wall of the air outlet 502.

[0041] When the air supply rod 105 drives the push plate 107 to move to the left along the inside of the conveying box 106, the internal pressure on the left side of the conveying box 106 drives the sealing plate 501 to move to the left, thereby connecting the conveying box 106 with the air supply pipeline, and delivering the gas along the air supply pipeline to the outer end face of the sealing plate 303, thereby realizing the gas delivery.

[0042] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
