Description

Technical Field

[0001] This application relates to the field of feeding device technology, and more specifically, to a feeding device for cement kilns using alternative fuels. Background Technology

[0002] Cement kiln alternative fuels refer to combustible waste materials used to replace some or all of the 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 cement kilns. The heat released can be used to calcine cement clinker, thereby playing the role of replacing fossil fuels.

[0003] The prior art CN222348024U discloses a feeding device for alternative fuel in a cement kiln, including a support frame, a feeding hopper on the support frame, an auxiliary feeding component installed in the feeding hopper, a conveyor rotatably installed in the support frame, and adjustment components installed on both sides of the support frame. The finished alternative fuel is fed into the feeding hopper by a loader, and the auxiliary feeding component causes the material in the feeding hopper to fall onto the conveyor through the feeding port for transportation, preventing the material from blocking the feeding port, thereby improving the feeding speed.

[0004] Because the auxiliary feeding device in the existing technology CN222348024U is located inside the feeding hopper, when the loader unloads, the alternative fuel is prone to impacting the motor, causing damage to the motor. In some cases, some of the alternative fuel may even get stuck between the half-gear and the gear frame, causing jamming and affecting the normal use of the auxiliary feeding device. Summary of the Invention

[0005] The purpose of this application is to provide a feeding device for cement kilns using alternative fuels, which can solve the technical problem that the auxiliary feeding components cannot be used normally due to material impact.

[0006] This application provides a cement kiln fuel-feeding device for alternative fuels, including a support frame, a plate chain conveyor, a hopper, and a dispersing component. The plate chain conveyor is mounted on the support frame, and the support frame is provided with multiple first support rods. The hopper is fixed above the support frame by the multiple first support rods and is located above the plate chain conveyor. Multiple guide plates are staggered from top to bottom inside the hopper. The dispersing component is mounted on the hopper and is located below the guide plates.

[0007] Preferably, the dispersing component includes a motor and a helical blade. The motor is disposed on the outer wall of the hopper, one end of the helical blade is rotatably connected to the inner wall of the hopper, and the other end of the helical blade passes through the hopper. The motor drives the helical blade to rotate.

[0008] Preferably, the dispersion components are provided in two sets.

[0009] Preferably, the lower end of the hopper has a funnel-shaped structure.

[0010] Preferably, the feeding device further includes a blocking assembly, which includes two first baffles arranged in parallel above the plate chain conveyor. One end of the first baffle is mounted on the first support rod, and the other end of the first baffle is connected to a plurality of second support rods, which are mounted on the bracket.

[0011] Preferably, the blocking assembly further includes a second baffle, which is disposed between the two first baffles. The second baffle and the two first baffles are spliced ​​together to form a U-shaped structure, and the discharge port of the hopper is located inside the U-shaped structure.

[0012] Preferably, the second baffle is fixed to the end of the first baffle by bolts.

[0013] The beneficial effects of this utility model are:

[0014] The cement kiln alternative fuel feeding device provided in this application uses a loader to feed the finished alternative fuel into the hopper. The finished alternative fuel falls onto the guide plate and moves downward along the guide plate, thereby reducing the impact of the alternative fuel on the dispersion component and extending the service life of the dispersion component. The dispersion component disperses the alternative fuel, improving the smoothness of the alternative fuel feeding. The alternative fuel in the hopper falls onto the plate chain conveyor and is then transported by the plate chain conveyor. Attached Figure Description

[0028] Example

[0029] like Figure 1-4 As shown in the figure, this application provides a cement kiln alternative fuel feeding device, including a support 1, a plate chain conveyor 2, a silo 3, and a dispersing component 4. The plate chain conveyor 2 is mounted on the support 1, and the support 1 is provided with a plurality of first support rods 5. The silo 3 is fixed above the support 1 by the plurality of first support rods 5 and is located above the plate chain conveyor 2. The interior of the silo 3 is provided with a plurality of guide plates 6 arranged in a staggered manner from top to bottom. The dispersing component 4 is mounted on the silo 3 and is located below the guide plates 6.

[0030] During use, a forklift is used to put the finished alternative fuel into the hopper 3. The finished alternative fuel falls onto the guide plate 6 and moves downward along the guide plate 6, thereby reducing the impact of the alternative fuel on the dispersion component 4 and extending the service life of the dispersion component 4. During the feeding process, the dispersion component 4 disperses the alternative fuel, improving the smoothness of the alternative fuel feeding. After the alternative fuel in the hopper 3 falls onto the plate chain conveyor 2, it is transported by the plate chain conveyor 2.

[0031] In this embodiment, the dispersing component 4 includes a motor 7 and a spiral blade 8. The motor 7 is installed on the outer wall of the hopper 3. One end of the spiral blade 8 is rotatably connected to the inner wall of the hopper 3, and the other end of the spiral blade 8 passes through the hopper 3. The motor 7 drives the spiral blade 8 to rotate. In use, the motor 7 drives the spiral blade 8 to rotate, and the spiral blade 8 disperses the alternative fuel, improving the smoothness of the alternative fuel feeding.

[0032] In this embodiment, two sets of dispersion components 4 are provided. The arrangement of two sets of dispersion components 4 can reduce the risk of alternative fuel accumulating or clogging in the silo 3 and ensure the continuous and uniform delivery of alternative fuel.

[0033] In this embodiment, the lower end of the hopper 3 has a funnel-shaped structure, which facilitates the concentration of material flow.

[0034] In this embodiment, in order to limit and block the alternative fuel, a blocking component 9 is also provided. The blocking component 9 includes two first baffles 10 arranged in parallel above the plate chain conveyor 2. One end of the first baffle 10 is installed on the first support rod 5, and the other end of the first baffle 10 is connected to a plurality of second support rods 11. The second support rods 11 are set on the bracket 1. Under the joint support of the plurality of first support rods 5 and the plurality of second support rods 11, the stability of the first baffle 10 is improved.

[0035] In this embodiment, the blocking component 9 also includes a second baffle 12, which is disposed between two first baffles 10. The second baffle 12 and the two first baffles 10 are spliced ​​together to form a U-shaped structure 13. The discharge port of the hopper 3 is located inside the U-shaped structure 13. The U-shaped structure 13 is used to block the alternative fuel and at the same time can prevent some of the alternative fuel from leaving the plate chain conveyor 2 due to splashing.

[0036] In this embodiment, the second baffle 12 is fixed to the end of the first baffle 10 by bolts 14. The bolts 14 connection method facilitates the assembly and disassembly of the first baffle 10 and the second baffle 12.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
