Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a dosing device for cement kiln utilizing alternative fuel. Background Art

[0002] Cement kiln alternative fuel refers to combustible waste used to replace part or all of traditional fossil fuels in the cement production process. These alternative fuels mainly include waste plastics, waste tires, coal gangue, etc. They usually have a high calorific value and can be fully burned in the cement kiln. The heat released can be used to calcine cement clinker, thereby playing the role of replacing fossil fuels.

[0003] When the existing cement kiln uses the alternative fuel dosing device to transport materials, it is necessary to use a forklift to place the stacked materials on the conveyor for transportation. During the transportation process, the forklift operator needs to keep loading materials without rest time, which will lead to a high work intensity for the forklift operator. Moreover, most of the conveyors in the existing cement kiln using the alternative fuel dosing device do not have baffles and mechanisms for adjusting the baffles, which easily causes the materials to fall during the transportation process, and the material storage space of the conveyor cannot be increased according to actual needs. In view of the above problems, the inventor proposes a cement kiln using an alternative fuel dosing device to solve the above problems. Utility Model Content

The baffles 3 on both sides of the conveyor 2 can ensure that the equipment has a certain material storage buffer function and avoid material overflow. The rotating roller 31 on the inner side of the baffle 3 can facilitate the transportation of materials. The inclination of the baffle 3 can also be adjusted by the adjustment component 6 according to the amount of conveyed materials to expand the storage space of the conveyor 2.

[0019] The auxiliary material discharge assembly 5 comprises a gear frame 51 . A support plate 41 is fixedly mounted on the top of the material discharge hopper 4 , and the gear frame 51 is slidably clamped in the support plate 41 .

[0024] By adopting the above technical solution, the driving motor 53 is started to drive the half gear 52 to rotate, and the half gear 52 engages with the tooth grooves on both sides of the tooth frame 51 to drive the tooth frame 51 to slide back and forth up and down in the support plate 41.

At the same time, the drive motor 53 is started to drive the half gear 52 to rotate. The half gear 52 is engaged with the tooth grooves on both sides of the tooth frame 51, driving the tooth frame 51 to slide back and forth up and down in the support plate 41. The tooth frame 51 drives the pressure plate 55 to move back and forth up and down in the lower hopper 4 through the connecting rod 54 to perform intermittent unloading. , so that the material in the hopper 4 falls onto the conveyor 2 through the discharge port 42 for transportation, preventing the material from blocking the discharge port 42.
