[0002] Jiaobaoshi is a high-quality hard refractory clay. The Al2O3 content in its raw ore is about 38%, and after high-temperature calcination, the Al2O3 content in the clinker is about 44%. After calcination, Jiaobaoshi is white, dense, stable, uniform, and shell-shaped in cross section. Jiaobaoshi is widely used in the production of refractory materials such as refractory bricks, refractory castables, and refractory spray coatings due to its high-quality sintering, high temperature resistance, and rapid cooling and heating resistance. It can also be used to make precision casting sand, precision casting shells and other precision casting profiles, as well as ceramic products, such as daily-use porcelain and industrial ceramics.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.
[0029] Specifically, Figure 1 As shown, an embodiment of the present application provides a calcining atmosphere regulating device 300, which is specifically used in a coke calcining device, wherein the coke calcination needs to be carried out in its calcining kiln 100, wherein the amount of coke needs to be controlled in the calcining kiln 100 to achieve sufficient combustion, wherein in the embodiment of the present application, a feed funnel 200 is provided in the control of the coke combustion process, and the feed funnel 200 is provided corresponding to the feed port, and the coke can enter the calcining kiln 100 through its feed funnel 200 and the feed port for high-temperature calcination.
[0030] Among them, an adjustment groove 210 is arranged on the feed funnel 200, and the adjustment groove 210 is connected with the feed port. The setting of the adjustment groove 210 can move the adjustment plate 320 in the adjustment groove 210, so as to facilitate the opening and closing of the feed port. The movement of the above-mentioned adjustment plate 320 is driven by its driving device 400 and the reduction device 500. Specifically, the driving device 400 is connected to the reduction device 500, and the output end of the reduction device 500 is connected to the gear 510. The gear 510 drives the adjustment plate 320 to move through its rack 310, so as to realize the adjustment function of the adjustment plate 320 for the opening and closing of the feed port.
[0031] In the embodiment of the present application, the driving device 400 is a driving motor. The speed of the driving motor is relatively high and cannot directly adjust and drive the adjustment plate 320. At this time, a reduction device 500 needs to be connected to the output end of the driving motor. The reduction device 500 is a reducer. In the embodiment of the present application, the reducer has a high reduction ratio, which can reduce the higher speed of the driving motor to a lower speed through the reducer, so that the output end of the reducer has a lower speed.
[0032] In the above, since the drive motor needs to control the adjustment plate 320 to open and close the feed port, the drive motor needs to rotate forward and reverse. In the embodiment of the present application, the drive motor needs to control the forward and reverse rotation through the positive and negative poles of its current to realize the opening and closing of the feed port.
[0033] In the above structure, the rack 310 is meshed with the gear 510 on the output end of the reduction device 500. When the gear 510 on the reduction device 500 rotates, the gear 510 drives the rack 310 to rotate. The movement direction is perpendicular to the direction of the output end of the reduction device 500. In order to maintain the accuracy of the movement direction of the rack 310, a rack limit block 600 is provided at the position where the rack 310 moves. A sliding groove 610 is provided on the rack limit block 600. The opening direction of the sliding groove 610 is the same as the moving direction of the rack 310, so that the rack 310 can move through the limiting effect of the sliding groove 610 to avoid the deviation of the rack 310.
[0034] One end of the rack 310 close to the adjustment plate 320 is connected to the adjustment plate 320, and the connection method is a detachable connection. When the rack 310 is connected to the adjustment plate 320, the linear movement of the rack 310 can drive the linear movement of the adjustment plate 320. In order to maintain the linear movement of the adjustment plate 320, a limiting plate 330 is set at the corresponding position of the adjustment plate 320, and a limiting groove 331 is set on the limiting plate 330. The limiting groove 331 is set corresponding to the cross-sectional shape of the adjustment plate 320. The adjustment plate 320 can be installed in the limiting groove 331 to avoid the adjustment plate 320 from being offset when the adjustment plate 320 moves.
[0035] The opening direction of the limiting groove 331 on the limiting plate 330 is set in the direction of the adjustment groove 210, so that the adjustment plate 320 can accurately enter the adjustment groove 210.
[0036] A stopper 700 is also provided on the limit plate 330, and the stopper 700 is mounted at both ends of the limit plate 330. When the rack 310 drives its adjustment plate 320 to move, in order to avoid excessive movement of the adjustment plate 320, the rack 310 will abut against the stopper 700 during the movement to prevent the adjustment plate 320 from excessive movement and damaging the feed port and the feed funnel 200.
[0037] In an embodiment of the present application, a plurality of positioning holes 332 are further provided on the limiting plate 330, and the plurality of positioning holes 332 are evenly arranged on both sides of the limiting plate 330. When the stop member 700 is installed on the limiting plate 330, the position of the stop member 700 can be set to adjust the moving distance of the adjusting plate 320, so as to facilitate the size control of the feed port.
[0038] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
