[0028] 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.

[0029] Please see Figure 1-4 This utility model provides a new technical solution: a ring-type calcining furnace for producing high-alumina heat-insulating refractory bricks, including a ring-type calcining furnace 1, a feeding channel 2 fixedly installed on the upper surface of the ring-type calcining furnace 1, an arc-shaped mounting groove 16 opened on the upper surface of the feeding channel 2, a fixing assembly, the fixing assembly is set on the ring-type calcining furnace 1, the fixing assembly includes two fixing plates 3, the two fixing plates 3 are respectively fixedly connected to the front and rear surfaces of the feeding channel 2, and multiple cylinders 4 are fixedly installed on the upper surface of both fixing plates 3;

[0030] Among them, the telescopic ends of the two multi-stage cylinders 4 are fixedly connected to the lifting plate 5, the lower surface of the lifting plate 5 is fixedly connected to two connecting plates 6, and the lower surface of the two connecting plates 6 is fixedly connected to a circular plate 7.

[0031] Among them, an arc-shaped positioning plate 8 is fixedly connected to the lower surface of the circular plate 7, and the lower end of the arc-shaped positioning plate 8 is slidably engaged into the inner wall of the arc-shaped mounting groove 16.

[0032] Furthermore, a plurality of fixing posts 11 are fixedly connected to the lower surface of the circular plate 7, and a circular cover 10 is fixedly connected to the lower surface of the plurality of fixing posts 11. The circular cover 10 is slidably connected to the inner wall of the feed channel 2.

[0033] Furthermore, rectangular grooves 9 are provided on both the left and right sides of the circular cover 10.

[0034] Furthermore, the fixing assembly also includes two mounting plates 12, which are fixedly connected to the left and right sides of the feed channel 2 respectively;

[0035] Cylinders 13 are fixedly mounted on the upper surfaces of both mounting plates 12.

[0036] Furthermore, L-shaped connecting brackets 14 are fixedly connected to the telescopic ends of both cylinders 13, and rectangular plates 15 are fixedly connected to the opposite faces of the two L-shaped connecting brackets 14.

[0037] Furthermore, the opposing surfaces of the two rectangular plates 15 slide through the interior of the feed channel 2.

[0038] Furthermore, one end of each of the two rectangular plates 15 is located inside the feed channel 2 and is slidably inserted into the inner wall of the corresponding rectangular groove 9.

[0039] Furthermore, when using the annular calcining furnace for producing high-alumina heat-insulating refractory bricks, when opening the circular cover 10, first start the two cylinders 13. The telescopic ends of the two cylinders 13 drive the two L-shaped connecting frames 14 to move to opposite positions. The two L-shaped connecting frames 14 drive the two rectangular plates 15 to move to opposite positions, so that the two rectangular plates 15 are both disengaged from the inner walls of the two rectangular grooves 9.

[0040] Then, two multi-stage cylinders 4 are activated. The telescopic ends of the two multi-stage cylinders 4 push the lifting plate 5 to move upward. The lifting plate 5 drives the circular plate 7 to move upward as a whole through the two connecting plates 6, thereby causing the circular cover 10 to detach from the inner wall of the feed channel 2, thus completing the removal of the circular cover 10.

[0041] When closing the circular cover 10, two multi-stage cylinders 4 are first activated. The telescopic ends of the two multi-stage cylinders 4 push the circular plate 7 downward through two connecting plates 6, and cause the arc-shaped positioning plate 8 to slide into the inner wall of the arc-shaped mounting groove 16.

[0042] When the lower end of the arc-shaped positioning plate 8 contacts the inner wall of the arc-shaped mounting groove 16, the two multi-stage cylinders 4 can be stopped to complete the installation of the circular cover 10. At this time, the two rectangular grooves 9 and the two rectangular plates 15 are set in a corresponding manner.

[0043] Among them, by setting the arc-shaped mounting groove 16 and the arc-shaped positioning plate 8, not only can the connection between the circular plate 7 and the feeding channel 2 be sealed, but the installation of the two rectangular grooves 9 and the two rectangular plates 15 can also be positioned, thereby improving the ease of installation of the two rectangular grooves 9 and the two rectangular plates 15.

[0044] Subsequently, two cylinders 13 are activated. The telescopic ends of the two cylinders 13 push the two rectangular plates 15 to move to the opposite position through the two L-shaped connecting brackets 14, so that the two rectangular plates 15 slide into the inner wall of the corresponding rectangular groove 9, thereby further fixing the circular cover 10 and improving the stability of the circular cover 10 during installation.

[0045] The fixed components facilitate the quick opening of the circular cover 10 by the staff, thereby improving the ease of opening the circular cover 10 and enhancing the practicality of the ring-type calcining furnace for the production of high-alumina heat-insulating refractory bricks.
