Description

Technical Field

[0001] This utility model relates to the field of denitrification catalyst production technology, and in particular to a dual-type drying oven. Background Technology

[0002] Plate-type denitrification catalysts are used in selective catalytic reduction (SCR) denitrification technology and are commonly used in industries such as power, steel, and cement. For the production, use, and maintenance of these catalysts, especially in the preparation process, the drying oven plays a crucial role. The drying oven typically includes a controlled temperature and humidity environment, heating or evaporating moisture from the material to ensure the catalyst material reaches predetermined performance standards after processing.

[0003] However, most traditional drying ovens adopt a single opening method for the oven cover. The opening range of the oven is limited by the single opening method, which particularly affects the later cleaning or maintenance. Therefore, this utility model provides a dual-opening and closing drying oven. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a closable drying oven, which solves the problems mentioned in the background.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution for a split-type drying oven: A split-type drying oven includes a furnace frame 1, with two support frames 11 installed on the front side of the bottom end of the furnace frame 1. The top ends of the two support frames 11 are connected to an inner furnace plate 12. An upper furnace cover 3 is rotatably connected to the top end of the furnace frame 1, and a lower furnace cover 2 is rotatably connected to the upper end of the furnace frame 1 below the inner furnace plate 12. A drying chamber is formed between the lower furnace cover 2 and the upper furnace cover 3. When the lower furnace cover 2 and the upper furnace cover 3 are closed, except for the inlets on both sides... The furnace frame 1 is enclosed, with the rest being sealed. A waste discharge chamber 16 is located at the top of the furnace frame 1, corresponding to the drying chamber. A waste discharge pipe 15 is connected to the middle of the waste discharge chamber 16. Multiple exhaust ports are provided between the waste discharge chamber 16 and the drying chamber. Water vapor and waste gas in the drying chamber are discharged into the waste discharge chamber 16 through multiple exhaust ports and then discharged through the dedicated waste discharge pipe 15. In addition, all materials in contact with the product in the furnace body are made of 304 stainless steel, taking into account both strength and corrosion resistance requirements, such as the conveyor roller 14.

[0023] Multiple heating tubes 13 and conveying rollers 14 are symmetrically distributed on the upper surface of the inner plate 12 and the inner side of the upper furnace cover 3. Both ends of the conveying rollers 14 are rotatably connected to brackets, and the conveying rollers 14 are fixed to the inner plate 12 or the upper furnace cover 3 by the brackets. Multiple heating tubes 13 can be controlled in different areas in the drying chamber, which makes it easy to adjust the temperature of each area. In addition, heating tubes 13 are also designed in the upper furnace cover 3 to facilitate the drying of the upper and lower parts of the catalyst and ensure the uniformity of drying.

[0024] The lower furnace cover 2 and the upper furnace cover 3 correspond to each other and are each provided with a shaft at one end. They are rotatably connected to the furnace frame 1 through the shaft. One end of the lower furnace cover 2 and the upper furnace cover 3 are rotatably connected to the furnace frame 1 through the shaft, and the other end is adjusted and controlled to open or close by the electric opening and closing assembly one and the electric opening and closing assembly two. The lower furnace cover 2 and the upper furnace cover 3 are controlled independently, and the angle range after they are opened is 0-120°.

[0025] An electric opening and closing assembly for opening or closing the upper furnace cover 3 is connected to the support frame 11. The electric opening and closing assembly includes a drive motor 4 and a reversing reducer 41 connected to the output end of the drive motor 4. A hollow shaft is connected through the output end of the reversing reducer 41, and a connecting screw 42 is threaded onto the hollow shaft. A connecting seat 43 is also installed on the front side of the upper furnace cover 3. The top end of the connecting screw 42 is hinged to the connecting seat 43. The reversing reducer 41 is fixedly installed on the support frame 11. The bottom end of the drive motor 4 is fixed to the support frame 11 through a U-shaped bracket. The connecting screw 42 is connected to the reversing reducer 41. The hollow shaft is threaded to the output end of the reducer 41. When it is necessary to open the upper furnace cover 3, the electric opening and closing components on the two support frames 11 can be synchronously controlled by the external controller. That is, the two drive motors 4 are controlled to rotate synchronously, so that they drive the hollow shaft to rotate through the reducer 41. When the hollow shaft rotates, since its inner wall is threaded to the connecting screw 42, it will drive the connecting screw 42 to move linearly upward on its inner wall. Thus, the two connecting screws 42 will synchronously push one end of the upper furnace cover 3 to rise, so that the upper furnace cover 3 can be opened. Conversely, the drive motor 4 can be reversed.

[0026] Two inclined supports 5 are also provided on the inner side of the bottom end of the furnace frame 1. An electric opening and closing assembly 2 for opening or closing the lower furnace cover 2 is installed on the inclined supports 5. The electric opening and closing assembly 2 has the same structural principle as the electric opening and closing assembly 1, and is also provided in two sets, respectively installed on the two inclined supports 5, and electrically connected to an external controller, adopting a synchronous control method. The electric opening and closing assembly 2 includes a reversing reducer 2 51 and a drive motor 2 52 installed on the inclined supports 5. A hollow shaft is also provided through the output end of the reversing reducer 2 51, and a connecting screw 2 53 is threaded onto the hollow shaft. A connecting seat 2 54 is installed on the front side of the lower surface of the lower furnace cover 2. The top end of the connecting screw 2 53 is connected to the connecting seat 2 54. The 54-phase hinge, the second deflector reducer 51, the second drive motor 52, the second connecting screw 53, and the second connecting seat 54 are all inclined. The second connecting screw 53 is threaded to the hollow shaft connected to the output end of the second deflector reducer 51. The second drive motor 52 is also fixed to the inclined support 5 through the U-shaped frame. The working principle and operation principle of the second electric opening and closing component are the same as those of the first electric opening and closing component, and will not be described in detail here. The purpose of its inclined setting is to better open the lower furnace cover 2. It should be added that a groove is opened on the front side of the lower furnace cover 2 corresponding to the support frame 11, and there is a sealing strip in the groove. The purpose is to facilitate better closing of the lower furnace cover 2 and avoid the support frame 11 affecting its closing effect.

[0027] The working principle of this utility model is as follows: During the catalyst drying process, the catalyst plate can be conveyed by the conveying roller 14. The conveying roller can be electrically driven, i.e., the transmission roller. Before the catalyst plate enters the drying chamber, the upper furnace cover 3 and the lower furnace cover 2 can be closed by controlling the electric opening and closing component one and the electric opening and closing component two. Then, the multiple heating tubes 13 in each area are controlled to work to raise the temperature, which facilitates the drying operation of the catalyst plate.

[0028] In addition, the upper furnace cover 3 and the lower furnace cover 2 can be opened to the maximum angle by controlling the electric opening and closing components one and two, thereby fully exposing the inside of the drying oven, which is more conducive to the subsequent cleaning and maintenance work of the staff and makes the operation more convenient.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
