[0002] At present, the material discharging of rail kilns is generally carried out by rolling transportation (i.e., the material is transported out of the furnace by rotating a stick). Due to the weight and inertia of the material, the speed of the stick cannot be too fast, resulting in a long discharging time. External gas is easily mixed into the furnace body, resulting in an impure sintering atmosphere for the material, and the sintered material cannot meet the performance requirements. This solution provides a furnace loading and unloading mechanism that can improve the efficiency of loading or unloading. Utility Model Content

The carrying slide 2 can be slid into the furnace body 4 to extract material 9 from the furnace body 4 or to place material 9 into the furnace body 4. The carrying slide 2 can also slide between the pushing and pulling mechanism 1 and the conveying device 3. The pushing and pulling mechanism 1 is used to drive the material 9 to transfer between the carrying slide 2 and the conveying device 3.

[0030] Specifically, the furnace body feeding and discharging mechanism is used to unload the furnace body 4. At this time, the carrying slide 2 slides into the furnace body 4 to extract the material 9 in the furnace body 4. The pushing and pulling mechanism 1 is used to push the material 9 on the carrying slide 2 onto the conveying device 3 when the carrying slide 2 carries the material 9 in the furnace body 4 and slides between the pushing and pulling mechanism 1 and the conveying device 3.

[0031] Alternatively, the furnace body loading and unloading mechanism is used to load materials into the furnace body 4, and the pushing and pulling mechanism 1 is used to pull the material 9 on the conveying device 3 onto the carrying slide 2 when the carrying slide 2 slides between the pushing and pulling mechanism 1 and the conveying device 3, and the carrying slide 2 slides into the furnace body 4 to lower the material 9 into the furnace body 4.

[0032] The furnace loading and unloading mechanism provided by the utility model can be used to unload or load the furnace body 4, and the material 9 is loaded and unloaded through the load slide 2, which can improve the stability and reliability of the material 9 loading, which is equivalent to the loading and unloading of the conventional track conveying mechanism, fork arm, etc. The contact area between the material 9 and the load slide 2 is large, and the material 9 is stable and reliable when transferred, which can realize faster loading and unloading of the material 9. The material 9 is loaded and unloaded relative to the load slide 2 by the push-pull material mechanism 1, which can simplify the difficulty of loading and unloading the load slide 2.

[0033] In one of the embodiments, the sliding direction of the carrying slide 2 is perpendicular to the line connecting the push-pull material mechanism 1 and the conveying device 3, so as to facilitate the turning and conveying of the material 9. Specifically, when the carrying slide 2 slides between the push-pull material mechanism 1 and the conveying device 3, the push-pull material mechanism 1, the carrying slide 2 and the conveying device 3 are in a straight line, and the sliding direction of the carrying slide 2 is perpendicular to the straight line.

[0034] In one embodiment, a limit strip 21 is provided on the side of the carrier slide 2 away from the furnace body 4, thereby preventing the material 9 from sliding out of the carrier slide 2 away from the furnace body 4, thereby improving the stability of the transfer of the material 9. Preferably, the carrier slide 2 is made of graphite material, which has wear resistance, heat resistance and self-lubricating properties, and can improve the sliding effect of the material 9 on the carrier slide 2.

[0035] In one of the embodiments, the furnace body feeding and discharging mechanism also includes a bracket 7 and a sliding frame 8 slidably set on the bracket 7, and the supporting slide 2 is set on the sliding frame 8. By setting the bracket 7 and the sliding frame 8, it is convenient to realize that the supporting slide 2 can extend independently into the furnace body 4.

[0036] In one embodiment, the conveying device 3 is a roller conveyor, preferably an unpowered roller conveyor. When the load-bearing slide 2 slides between the push-pull mechanism 1 and the conveying device 3, the upper end surface of the load-bearing slide 2 is flush with the conveying plane of the conveying device 3.

[0037] In one embodiment, the push-pull material mechanism 1 includes a linear drive mechanism 11, a push-pull rod 12 arranged at the output end of the linear drive mechanism 11, and a push-pull block 13 arranged at the end of the push-pull rod 12. When the furnace body feeding and discharging mechanism is used to unload the furnace body 4, the push-pull block 13 is used to push the material 9 on the carrying slide 2 onto the conveying device 3. The push-pull block 13 is only used to push the material 9. The push-pull block 13 can be only a block structure. When the furnace body feeding and discharging mechanism is used to load the furnace body 4, the push-pull block 13 is used to pull the material 9 on the conveying device 3 onto the carrying slide 2. The push-pull block 13 is used to pull the material 9. At this time, the push-pull block 13 is provided with an interlocking structure that engages with and separates from the material 9. The specific interlocking structure can be, for example, a pin driven by the linear drive mechanism 11 to cooperate with a pin hole on the material 9, or a telescopic interlocking block can be driven to cooperate with a matching groove on the material 9.

[0038] In one embodiment, a roller 131 that rolls with the support slide 2 is disposed at the bottom of the push-pull block 13 . At this time, the friction force can be reduced when the push-pull block 13 moves on the support slide 2 , thereby reducing the driving burden of the linear drive mechanism 11 .

[0039] In one embodiment, the linear drive mechanism 11 is a linear module, which has the characteristics of large load capacity and high control accuracy. The push-pull material mechanism 1 also includes a support plate 14 arranged on the linear module housing, and a sliding hole 141 is arranged on the support plate 14. The push-pull rod 12 is slidably arranged in the sliding hole 141. By providing the support plate 14, the sliding stability of the push-pull rod 12 can be improved. In other embodiments, the linear drive mechanism 11 can also use a cylinder or a hydraulic cylinder.

Preferably, the telescopic mechanism 43 is a cylinder, a hydraulic cylinder or an electric cylinder.

[0045] A sealing ring 45 is provided on the opposite side of the door surface 421 and / or the opening 41, which can further improve the sealing effect of the flip door 42 on the opening 41. When both the door surface 421 and the opening 41 are provided with sealing rings 45, the two groups of sealing rings 45 can be staggered to further improve the sealing effect.

The lifting plate 62 is lifted and lowered from the gap between the roller bodies 51 of two adjacent roller conveyor mechanisms 5.

[0048] In this embodiment, when the furnace body in-and-out material mechanism is used to unload the furnace body 4, the material 9 is transported to the opening 41 by the roller conveyor mechanism 5, and then the lifting mechanism 61 drives the lifting plate 62 to lift the material 9, and then the carrying slide 2 moves to the bottom of the material 9, and finally the lifting mechanism 61 drives the lifting plate 62 to reset, and the carrying slide 2 carries the material 9 to leave the furnace body 4 from the opening 41. When the furnace body in-and-out material mechanism is used to load the furnace body 4, the carrying slide 2 carries the material 9 and moves into the furnace body 4, and then the lifting mechanism 61 drives the lifting plate 62 to lift the material 9, and the carrying slide 2 is pushed out of the furnace body 4 from the opening 41, and finally the lifting mechanism 61 drives the lifting plate 62 to reset, and the material 9 is carried and transported by the roller conveyor mechanism 5.
