Description

Technical Field

[0001] The utility model relates to the technical field of fuel processing equipment, in particular to alternative fuel feeding equipment with a crushing mechanism. Background Art

[0002] The production process of cement requires a large amount of coal for its combustion supply, and the combustion cost of coal is gradually increasing. For this reason, most of the biomass alternative fuels on the market are now used for combustion supply. Biomass fuel is a fuel based on plant biomass, including various wastes such as wood, seed shells, and straw. It can reduce the cost of cement production. When biomass fuel needs to be crushed before use, an alternative fuel feeding equipment with a crushing mechanism is proposed for use.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN218057569U discloses a feeding device for biomass fuel molding processing, which belongs to the technical field of fuel processing equipment. In this technical scheme, it includes a base, a support frame and a conveyor belt body. The support frame is welded to the top of the base, and the conveyor belt body is arranged on the inner side of the support frame. A feeding mechanism is arranged on one side of the base, and a cleaning mechanism is arranged on the other side of the base. The feeding mechanism includes an electric cylinder, a connecting rod, a connecting plate, a baffle, a storage box and two groups of support plates. The electric cylinder is arranged on the top of the base, and the connecting rod is fixedly connected to the output end of the electric cylinder. In this feeding device for biomass fuel molding processing, the biomass molding fuel is dispersedly fed to the top of the conveyor belt body through the circular notch on the top of the storage box and the first discharge pipe, so that the biomass molding fuel is not easy to stack together when it is put into the conveyor belt body, so that the powdered biomass molding fuel is not easy to leak from the bottom of the conveyor belt body, saving resources.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that since alternative fuels are generally waste products such as wood and straw, these biomass fuels are in finished blocks before use. Block equipment cannot be directly added for combustion, and the biomass fuel needs to be put into the device after being crushed. Since the fuel is heavy, it is more laborious for the staff to carry it back and forth. The existence of these problems has affected the use of the device. Utility Model Content

After the feeding box 3 is filled with crushed materials, the sliding plate 43 is used to slide in the sliding groove 42 to slide the feeding box 3 to the combustion equipment, and then the pressing device 3 is used to press the pressing device 3. By connecting the side rod 36 and the pneumatic tube 33, the lifting rod 34 below the feeding box 3 is lifted up and down, and according to the setting of the connecting rod 35, the bottom rear of the feeding box 3 is simultaneously in a certain tilted state, so that the feeding box 3 can pour the full crushed materials into the interior of the incineration equipment. Finally, after the crushed materials in the feeding box 3 are poured out, the lifting rod 34 is lowered, so that the feeding box 3 is flatly located above the bottom plate 31, and then the setting of the slide plate 43 and the sliding groove 42 is used to return the feeding box 3 to its original position. After returning to its original position, the switch valve 16 can be continued to be opened to allow the crushed materials in the crushing cylinder 1 to flow out for the next feeding.
