Description

Technical Field

[0001] The present invention relates to the technical field of tunnel kilns, and particularly to a mobile tunnel kiln with a mobile stop gate. Background Art

[0002] Currently, for the tunnel kiln used for firing brick blanks, a double-channel stop gate is adopted on the same kiln body. When the kiln body needs to move, due to the blockage of the brick blanks in the kiln furnace, the double-channel stop gate must be opened simultaneously in order to move forward. The moving stop gate of the kiln body cannot play a sealing role, resulting in a large amount of useless air entering the drying section of the kiln furnace and entering the flue gas purification system, increasing the oxygen content in the discharged flue gas, increasing the operating cost of the flue gas purification system, and increasing the risk of exceeding the data emission standard. Summary of the Invention

[0003] The purpose of the present invention is to provide a mobile tunnel kiln with a mobile stop gate to solve the problems existing in the above-mentioned prior art, and it can always keep one of the stop gates in a lowered closed state when the kiln body moves forward, solving the problem of the inability to seal the inside of the kiln during the movement of the kiln body, reducing the entry of useless air into the drying section of the kiln furnace, and reducing the oxygen content in the discharged flue gas.

[0004] To achieve the above purpose, the present invention provides the following solutions:

[0005] The present invention provides a mobile tunnel kiln with a mobile stop gate, including a mobile kiln body, a first stop gate, a second stop gate, and a mobile platform; the second stop gate is arranged on the mobile kiln body, the mobile platform is arranged at the top front end of the mobile kiln body, the bottom of the mobile platform is the inner cavity of the mobile kiln body, the first stop gate is arranged on the mobile platform, the mobile platform is slidably connected with the mobile kiln body, and the mobile platform can move to the top of the kiln top of the mobile kiln body.

[0006] Preferably, the first stop gate is arranged at the front end of the mobile platform.

[0007] Preferably, both sides of the bottom of the mobile platform are mobile tracks arranged on the mobile kiln body, and support wheels cooperating with the mobile tracks are arranged on both sides of the mobile platform.

[0008] Preferably, two support wheels are respectively arranged on both sides of the mobile platform, and the support wheels are connected with the mobile platform through support shafts.

[0009] Preferably, the bottom of the mobile kiln body is connected with a kiln body walking track arranged on the foundation through kiln body support wheels.

[0010] The present invention has obtained the following beneficial technical effects compared with the prior art:

[0011] The mobile tunnel kiln with a mobile cut-off door provided by the present invention is provided with a mobile platform with a cut-off door at the top of the mobile kiln body. When the mobile kiln body moves, the mobile platform can always seal the inner cavity of the kiln with the cut-off door, ensuring that there is always a cut-off door in the falling closed state when the kiln body moves forward. This solves the problem of the inability to seal the inside of the kiln when the kiln body is moving, reduces the entry of useless air into the drying section of the kiln furnace, and reduces the oxygen content in the discharged flue gas.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] The purpose of the present invention is to provide a mobile tunnel kiln with a mobile cut-off door to solve the problems existing in the prior art.

[0020] To make the above objects, features, and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0021] The mobile tunnel kiln with a movable cut-off door in this embodiment is as follows Figure 1 As shown, it includes a movable kiln body 1, a first cut-off door 2, a second cut-off door 3 and a mobile platform 4; the second cut-off door 3 is arranged on the movable kiln body 1, the mobile platform 4 is arranged at the top front end of the movable kiln body 1, the bottom of the mobile platform 4 is the inner cavity of the movable kiln body 1, the first cut-off door 2 is arranged on the mobile platform 4, the mobile platform 4 is movably connected to the movable kiln body 1, and the mobile platform 4 can move to the top of the kiln roof of the movable kiln body 1.

[0022] In this specific embodiment, the first cut-off door 2 is arranged at the front end of the mobile platform 4; on both sides of the bottom of the mobile platform 4 are mobile tracks 5 arranged on the movable kiln body 1, and on both sides of the mobile platform 4 are support wheels 6 that are cooperatively connected with the mobile tracks 5; specifically, two support wheels 6 are respectively arranged on both sides of the mobile platform 4, and the support wheels 6 are connected to the mobile platform 4 through support shafts.

[0023] In this specific embodiment, the bottom of the movable kiln body 1 is connected to the kiln body walking track 8 arranged on the foundation through the kiln body support wheels 7; when the movable kiln body 1 moves, the kiln body support wheels 7 roll along the kiln body walking track 8 to realize the movement of the movable kiln body 1.

[0024] The moving process of the mobile tunnel kiln with a movable cut-off door in the present invention is as follows:

[0025] Figure 1 As shown in the figure, it is a schematic diagram of the initial state of the mobile tunnel kiln with a movable cut-off door before moving. When the kiln body needs to move, as Figure 2 shown, first open the second cut-off door 3 at the fixed position on the movable kiln body 1. Since the mobile platform 4 is movably connected, when the movable kiln body 1 moves forward, under the block of the brick stack, the position of the mobile platform 4 will not change. As the movable kiln body 1 moves forward, the position of the mobile platform 4 on the movable kiln body 1 gets closer and closer to the rear end 4, and finally it is completely located on 4. After the movable kiln body 1 moves forward to the corresponding position, as Figure 3 shown, lower the second cut-off door 3, then open the first cut-off door 2 on the mobile platform 4. After the mobile platform 4 moves forward to the initial position, as Figure 4 shown, lower the first cut-off door 2 to complete one movement of the kiln body. Cycle in turn. When the kiln body moves forward, there is always a cut-off door in the lowered (closed) state, and at the same time, the problem of brick billet blockage in the kiln is solved.

[0026] The present invention uses specific examples to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
