Description

Technical Field

[0001] This utility model specifically relates to a combustion furnace door opening and closing structure based on refractory materials. Background Technology

[0002] A combustion furnace is a device used to heat or burn materials, commonly used in industrial production. It generates high temperatures by burning fuel to process or handle raw materials.

[0003] Existing combustion furnace door structures are relatively simple, with the door typically connected to the furnace body via hinges. When opening and closing the door, it rotates outward around the hinge axis, and the door is either tilted or vertical relative to the mounting end face. This results in the door occupying a large space outside the furnace body after opening, obstructing the door when there are external obstacles, making opening and closing inconvenient. Furthermore, it is not easy to quickly lock the door position during opening and closing. Excessive opening and closing range results in a large furnace opening, which is not conducive to furnace insulation. Conversely, insufficient opening and closing range affects the addition of fuel into the furnace body through the opening. Therefore, we propose a combustion furnace door structure based on refractory materials. Utility Model Content

[0004] The purpose of this invention is to provide a combustion furnace door structure based on refractory materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combustion furnace door structure based on refractory materials, comprising:

[0006] A combustion furnace body, wherein a feed inlet is provided at one end of the combustion furnace body and a combustion outlet is provided at the other end;

[0007] At least two door assemblies are symmetrically installed on the combustion furnace body to cover the feed inlet, and when opening and closing, the door assemblies rotate in a direction parallel to the end face of the combustion furnace body;

[0008] The mounting block is fixed to one end of the combustion furnace body, and the lower surface of the mounting block is provided with a locking structure that cooperates with the door assembly, so as to lock the position of the door assembly through the locking structure when opening and closing.

[0009] Preferably, the door assembly includes a door and a gear, the gear being mounted side-by-side on one end face of the combustion furnace body via a shaft, and the door being fixedly connected to the lower surface of the gear.

[0010] Preferably, the door body is semi-circular, and the front surface of the door body has a handle.

[0011] Preferably, a sealing protrusion is formed on the lower end of one side wall of the door body, and two door bodies are provided, with a sealing groove corresponding to the sealing protrusion on the other door body.

[0012] Preferably, the door body is made of fire-resistant steel.

[0013] Preferably, the locking block structure includes a spring, a locking block, and an inclined surface. The locking block is slidably disposed on the mounting block, and the locking block has a spring. An inclined surface that cooperates with the door assembly is provided on one side of the lower end of the locking block.

[0014] Preferably, there are two card blocks, which are symmetrically distributed along the center of the long side of the mounting block.

[0015] Preferably, the inner side of the combustion furnace body is provided with refractory high-alumina bricks.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features two door components, a mounting block, and a locking structure, facilitating quick adjustment of the feed inlet opening. It avoids the problems associated with traditional hinged connections between the door and the combustion furnace, which make it difficult to quickly lock the door position when rotating, leading to excessive or insufficient opening. Furthermore, the door's rotation outwards from the combustion furnace occupies external space. This device rotates the door parallel to the combustion furnace end face, reducing the occupied external space. During rotation, the door position can be quickly locked, facilitating adjustment of the opening degree. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a combustion furnace door opening and closing structure based on refractory materials, comprising:

[0025] The combustion furnace body 1 has a feed inlet 2 at one end and a combustion port 5 at the other end;

[0026] At least two door assemblies 3 are symmetrically installed on the combustion furnace body 1 to cover the feed inlet 2, and when opening and closing, the door assemblies 3 rotate in a direction parallel to the end face of the combustion furnace body 1.

[0027] To reduce the traditional single-door horizontal rotation, which is perpendicular to the end face of the combustion furnace body 1, it occupies a large external space and is inconvenient to open and close when there are objects outside.

[0028] Mounting block 4 is fixed to one end of the combustion furnace body 1, and the lower surface of mounting block 4 is provided with a locking structure that cooperates with door assembly 3, so as to lock the position of door assembly 3 through the locking structure when opening and closing.

[0029] It facilitates quick locking of the door component 3, allowing for convenient adjustment of the opening and closing range when the door is opened and closed.

[0030] In this embodiment, preferably, the door assembly 3 includes a door 301 and a gear 303. The gear 303 is mounted side by side on one end face of the combustion furnace body 1 via a shaft, and the door 301 is fixedly connected to the lower surface of the gear 303.

[0031] This allows one door 301 to rotate while the other door 301 rotates, thus improving the efficiency of opening and closing.

[0032] In this embodiment, preferably, the door body 301 is semi-circular, and the front surface of the door body 301 has a handle 302.

[0033] This facilitates better movement of the 301 door body.

[0034] In this embodiment, preferably, a sealing protrusion 3011 is formed by the lower end of one side wall of the door body 301 protruding outward. There are two door bodies 301, and the other door body 301 is provided with a sealing groove 3012 corresponding to the sealing protrusion 3011.

[0035] This design facilitates better sealing of the combustion furnace body 1 when no fuel is added, reducing heat transfer to the outside and improving the overall insulation effect of the combustion furnace body 1. In addition, it can also effectively prevent external animals from accidentally entering the interior of the combustion furnace body 1 when not in use.

[0036] In this embodiment, preferably, the door body 301 is made of fire-resistant steel.

[0037] It facilitates the improvement of fire resistance.

[0038] In this embodiment, preferably, the locking block structure includes a spring 401, a locking block 402 and an inclined surface 403. The locking block 402 is slidably disposed on the mounting block 4. The locking block 402 has a spring 401 on it. An inclined surface 403 that cooperates with the door assembly 3 is provided on one side of the lower end of the locking block 402.

[0039] This allows for quick and easy securing of the door assembly 3, ensuring it is locked in place once the opening and closing angle is adjusted.

[0040] In this embodiment, preferably, two card blocks 402 are provided, and the two card blocks 402 are symmetrically distributed along the center of the long side of the mounting block 4.

[0041] This facilitates better engagement between the card block 402 and the gear 303 on the door body 301.

[0042] In this embodiment, preferably, refractory high-alumina bricks 6 are provided on the inner side of the combustion furnace body 1;

[0043] The main materials of refractory high-alumina brick 6 are aluminum oxide and silicon dioxide, with aluminum oxide content greater than 48%.

[0044] The working principle and usage process of this utility model are as follows: When in use, the door body 301 is rotated by pulling the handle 302. At this time, the gear 303 and the shaft rotate, and the two door bodies 301 are driven to move the other door body 301 through the meshing of the two gears 303, so that the two door bodies 301 move away from each other. At the same time, the locking block 402 is inserted from one tooth groove on the door body 301 to the other tooth groove through the inclined surface 403 until the opening width of the feed port 2 is adjusted. The rotation of the gear 303 is restricted by the straight surface on the other side of the lower end of the locking block 402, so that the positions of the two door bodies 301 can be quickly locked. The operation is simple.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
