[0025] Further, exhaust mechanism further includes first warehouse pneumatic drawer pull 23, first warehouse pneumatic drawer pull 23 is fixedly installed on the surface of first warehouse cavity 2, the surface of lower avoiding blocker 12 is fixedly installed with second warehouse pneumatic drawer pull 24, the surface of feed avoiding blocker 11 is fixedly installed with feeding device hydraulic push-pull rod 25, the output end of feeding device hydraulic push-pull rod 25 is fixedly connected with first push plate 26, the surface of first push plate 26 is fixedly connected with second push plate 27, the output end of first warehouse pneumatic drawer pull 23 is fixedly connected with first drawer plate 210, the output end of second warehouse pneumatic drawer pull 24 is fixedly connected with second drawer plate 211, the inner side of feeding device sealing warehouse 22 is fixedly installed with oxygen concentration detector 212, by the setting of oxygen concentration detector 212, the oxygen concentration in feeding device sealing warehouse 22 can be monitored, so that when oxygen concentration is lower than the required limit, feeding device hydraulic push-pull rod 25 pushes large block material in feeding device sealing warehouse 22 into main furnace 1, and a small amount of combustible gas mixed into feeding device sealing warehouse 22 can be squeezed out by opening second exhaust sealing nitrogen gas nozzle 29, so that the feeding process is completed when it is below the limit requirement.

[0026] Furthermore, the second exhaust sealing nitrogen nozzles 29 are arranged in two groups at the bottom end of the feed avoider 11, and the first push plate 26 and the second push plate 27 are both movable on the inner side of the sealed bin body 22 of the feeding device. Through the arrangement of the first push plate 26 and the second push plate 27, the large block materials entering the sealed bin body 22 of the feeding device can be pushed, so that the large block materials can enter the main furnace 1 under the action of the first push plate 26 and the second push plate 27.

[0027] Furthermore, the first drawer panel 210 moves on the inner side of the first bin cavity 2 and the upper damper 13, and the second drawer panel 211 moves on the inner side of the lower damper 12 and the second bin cavity 21. Through the setting of the first drawer panel 210 and the second drawer panel 211, when the first bin body pneumatic drawer push-pull 23 and the second bin body pneumatic drawer push-pull 24 drive the first drawer panel 210 and the second drawer panel 211 to open, large pieces of material can fall from the first bin cavity 2 into the second bin cavity 21, and from the second bin cavity 21 into the sealed bin body 22 of the feeding device, so as to facilitate the entry of large pieces of material into the main furnace 1.

Through the staggered distribution of the connecting plates 34 in the first bin cavity 2 and the second bin cavity 21, the falling speed of large pieces of material falling on the connecting plates 34 can be slowed down, thereby reducing the impact of the large pieces of material on the first drawer board 210 and the second drawer board 211, which is beneficial to extending the service life of the first drawer board 210 and the second drawer board 211.

[0029] Furthermore, one end of the spring 32 is fixedly connected to the fixed rod 31, and the other end of the spring 32 is fixedly connected to the telescopic rod 33. The telescopic rod 33 moves on the inner side of the fixed rod 31. Through the setting of the spring 32, when a large piece of material falls on the connecting plate 34, the telescopic rod 33 will move on the inner side of the fixed rod 31 under the action of the connecting plate 34, and cause the spring 32 to deform. Through the elastic properties of the spring 32, the impact of the falling large piece of material on the connecting plate 34 and the fixed plate 3 can be reduced, thereby achieving protection of the fixed plate 3 and the connecting plate 34.

[0030] Working principle: When in use, bulk materials enter the first bin cavity 2 from the feed port of the upper resistor 13, and the first bin pneumatic drawer push-pull 23 opens the first drawer plate 210. At this time, the bulk materials fall from the first bin cavity 2 into the second bin cavity 21. At the same time, the first exhaust sealing nitrogen nozzle 28 opens, sprays nitrogen and squeezes the air in the second bin cavity 21 out of this cavity. Then the first bin pneumatic drawer push-pull 23 closes the first drawer plate 210, and at the same time, the first exhaust sealing nitrogen nozzle 28 stops working; the second bin pneumatic drawer push-pull 24 opens the second drawer plate 211. At this time, the bulk materials fall from the second bin cavity 21 into the sealed bin 22 of the feeding device. The sealed bin 22 of the feeding device is equipped with an oxygen concentration detector 212. If the oxygen concentration is lower than the required limit at this time, the hydraulic push-pull rod 25 of the feeding device Push the first push plate 26 and the second push plate 27 to enable the bulk materials in the sealed bin 22 of the feeding device to enter the main furnace 1 under the action of the first push plate 26 and the second push plate 27, and then pull the hydraulic push-pull rod 25 of the feeding device back to its original position. At this time, the second exhaust sealing nitrogen nozzle 29 is opened to squeeze out a small amount of combustible gas mixed into the sealed bin 22 of the feeding device. When the concentration reaches below the limit requirement, the feeding process is completed and preparations are made for the second cycle feeding to be started; if there is an occasional emergency, at this time, the oxygen concentration is higher than the required limit, the second exhaust sealing nitrogen nozzle 29 is opened to squeeze out the oxygen, and the mixed gas of air and nitrogen is discharged to the outside of the sealed bin 22 of the feeding device until the oxygen concentration is lower than the required limit. At this time, the hydraulic push-pull rod 25 of the feeding device pushes the bulk materials in the sealed bin 22 of the feeding device into the main furnace 1;

[0031] When the bulk material enters the first bin cavity 2 and the second bin cavity 21, it will first fall on the connecting plate 34, so that the falling speed of the bulk material is slowed down, and the first drawer plate 210 and the second drawer plate 211 can be protected. The connecting plate 34 is impacted by the bulk material, and the telescopic rod 33 will move on the inner side of the fixed rod 31 under the action of the connecting plate 34. At this time, the spring 32 is deformed, which can alleviate the impact force of the falling bulk material to a certain extent, thereby reducing the loss of the fixed plate 3 and the connecting plate 34.

[0032] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
