[0001] This application relates to the field of kiln technology, and in particular to an exhaust channel for a refractory material kiln. Background Technology

[0002] When refractory materials are calcined in a kiln, the exhaust gas contains a certain amount of ash-like impurities. These ash-like impurities do not directly threaten the exhaust pipe, but after long-term use, they will adhere to the inner wall, forming an irregular structural layer that obstructs airflow. At the same time, the subsequent cleaning work is also very difficult, which is not conducive to later maintenance.

[0003] Patent document CN220250697U discloses an exhaust channel for a refractory material kiln, including a cylindrical filter cylinder. The internal cavities of the cylindrical filter cylinder are filled with a filtrate, and the upper liquid level of the filtrate is located below a baffle plate. This invention can effectively filter dust impurities in high-temperature gases, dissolving most of them into the solvent, which has certain positive significance. However, the internal structure of the entire cylindrical filter cylinder is complex and requires liquid filling, making it very inconvenient for actual on-site implementation. Utility Model Content

[0020] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0021] like Figure 1-5 As shown, an exhaust channel for a refractory kiln includes a mounting frame 6 and a first pipe body 1, a second pipe body 2, a first bend 3, and a second bend 4 connected to the mounting frame 6. The top of the first pipe body 1 is connected to the bottom of the second pipe body 2, one end of the first bend 3 is connected to the top of the second pipe body 2, and the other end of the first bend 3 is connected to one end of the second bend 4. A rotating shaft 5 is provided in the second pipe body 2, and a scraper 52 for scraping impurities inside the second pipe body 2 is provided on the rotating shaft 5. A first opening 10 is provided on the first pipe body 1, and a guide plate 12 is hinged to the lower edge of the first opening 10. A clearance groove 14 for accommodating the rotating shaft 5 is provided on the guide plate 12. A baffle 15 is hinged to the edge of the clearance groove 14.

[0022] The diameter of the first tube 1 is relatively larger than that of the second tube 2, so as to facilitate the subsequent control of the guide plate 12 and the rotation shaft 5.

[0023] The guide plate 12 can rotate relative to the first opening 10. When the guide plate 12 is vertically set, it is located in the first opening 10 and can block the first opening 10. When the guide plate 12 is inside the first tube 1, it is tilted and the end away from the hinge rests inside the first tube 1. The clearance slot 14 on it can just make way for the rotating shaft 5. The baffle 15 hinged on the clearance slot 14 can cover part of the clearance slot 14 after rotation. In this state, rotating the rotating shaft 5 can drive the scraper 52 to rotate, so that the scraper 52 scrapes off the impurities inside the second tube 2. The fallen impurities fall onto the tilted guide plate 12 and can be cleaned out from the first outlet.

[0024] The baffle 15 is mainly used to prevent impurities from falling into the lower part of the first tube 1 to a certain extent.

[0025] The rotation of the rotating shaft 5 can be achieved by the fixed rod 50 and the bearing. Specifically, one end of the fixed rod 50 is set at one end of the rotating shaft 5, and the other end of the fixed rod 50 is set on the inner wall of the first tube 1. Multiple fixed rods 50 can be arranged circumferentially.

[0026] When the end of the guide plate 12 away from the hinge overlaps the inner wall of the first tube 1, there is a certain gap between the edge of the clearance slot 14 and the outer wall of the rotating shaft 5, so that the clearance slot 14 interferes with the rotation of the rotating shaft 5.

[0027] In practice, the first pipe body 1 is the main pipe body, which is a relatively long section of the entire exhaust channel. Therefore, after the rotating shaft 5 and scraper 52 are installed, the impurities inside can be cleaned, and the scraped impurities can be cleaned to the outside of the entire exhaust channel through the guide plate 12 to avoid contaminating other parts of the exhaust channel. The entire exhaust channel has a simple structure, is easy to install, and has a good cleaning effect.

[0028] In some further embodiments, the rotating shaft 5 is provided with a connecting rod 51, and there are multiple connecting rods 51, which are spaced apart along the axial direction of the rotating shaft 5; one end of the connecting rod 51 is connected to the outer wall of the rotating shaft 5, and the other end of the connecting rod 51 is connected to the scraper 52.

[0029] The length of the scraper 52 is the same as the length of the rotating shaft 5. The scraper 52 can be a metal sheet with a certain degree of elasticity to adaptively scrape away "stubborn" impurities.

[0030] In some further embodiments, the interior of the first tube 1 is provided with an overlapping plate 16, which is disposed on the inner wall of the first tube 1.

[0031] In order to avoid the impact of the guide plate 12 abutting against the inner wall of the first tube 1, a lap plate 16 is specially provided to overlap the guide plate 12 in the inclined state, which can both ensure the lap strength and avoid damage to the inner wall of the first tube 1.

[0032] In some further embodiments, the first tube 1 is provided with a second opening 11, and the second opening 11 is provided with a cover.

[0033] When the second opening 11 is opened, the operator can rotate the rotating shaft 5. In other embodiments, a rotating ring can be provided on the rotating shaft 5 to facilitate the operator's rotation.

[0034] In some further embodiments, the mounting frame 6 is provided with a limiting slide groove 60 and a fixing hole. The number of fixing holes is multiple and they are arranged at intervals along the sliding direction of the limiting slide groove 60. The first bend 3 and the second bend 4 are mounted on the mounting frame 6 through a connecting frame.

[0035] Mounting bracket 6 is mainly used to fix and adjust the first pipe body 1, the second pipe body 2, the first bend 3, and the second bend 4.

[0036] Impurities tend to accumulate at the bends of the first bend 3 and the second bend 4. Therefore, separate first bend 3 and second bend 4 are provided to facilitate subsequent replacement.

[0037] When replacing, the bolts in the fixing holes can be removed, and the first bend 3 and the second bend 4 can be disassembled and installed by hoisting.

[0038] In some further embodiments, the connecting frame includes an upper clamp 70 and a lower clamp 71, which are connected by bolts. The lower clamp 71 includes a sliding arm 72, one end of which is connected to the outer wall of the lower clamp 71, and the other end of which is located in the limiting groove 60. The sliding arm 72 is fixed in the fixing hole by bolts.

[0039] The upper clamp 70 and the lower clamp 71 are used to fix the first bend 3 and the second bend 4. A sliding arm 72 is specially provided on the lower clamp 71 to prevent the first bend 3 or the second bend 4 from falling directly due to accidental loosening of the bolts between the upper clamp 70 and the lower clamp 71.

[0040] The limiting sliding groove is mainly used to allow the sliding arm 72 to move in the horizontal plane first, so as to ensure precise up and down sliding.

[0041] A pull ring 13 can be provided on the guide plate 12 to facilitate the operator to control its rotation. When the guide plate 12 is in a vertical state, it can also block the first opening 10. In other embodiments, pins or holes can be provided on the edge of the guide plate 12 or the first opening 10 to fix the guide plate 12 in a vertical state.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
