Description

Technical Field

[0001] This utility model relates to a feeding device, and more particularly to a feeding device for a coke conveyor belt. Background Technology

[0002] The dry quenching workshop has four coke conveyor belts. During daily operation, the belts are connected by transfer stations. The transfer stations are equipped with chutes for receiving materials. When the coke reaches each transfer station, it falls directly onto the smooth chute wall. Due to the large drop, the coke directly impacts the chute wall, causing severe wear at the drop point and frequent material leakage. It can only be repaired by welding on the outside, but the service life is still relatively short.

[0003] Based on the above problems, the inventors proposed a coke conveyor belt feeding device, which greatly improves the wear resistance of the chute by modifying the chute structure, thereby ensuring smooth production operation. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a coke conveyor belt unloading device.

[0005] This utility model is achieved through the following technical solution: a coke conveyor belt unloading device is provided, including an unloading mechanism for receiving material falling from the conveyor belt. The unloading mechanism includes a vertically arranged feed pipe, an inclined guide pipe, and a vertically arranged discharge pipe, which are connected sequentially. Coke falling from the upper conveyor belt enters the feed pipe, passes through the guide pipe, enters the discharge pipe, and is discharged onto the lower conveyor belt. Wear-resistant liners are installed on the inner walls of both the guide pipe and the discharge pipe. A through hole is provided on the lower wall of the guide pipe at a position corresponding to the coke falling point. A cover plate that can cover the through hole and can be opened and closed is installed on the outer wall of the guide pipe. The cover plate blocks the through hole, forming a material trough for storing coke at the through hole.

[0006] Preferably, the lower end of the cover plate is hinged to the outer wall of the guide tube, and the upper end of the cover plate is connected to the outer wall of the guide tube through a connector.

[0007] Preferably, the connector includes a connecting screw fixed to the outer wall of the feed tube, an ear plate fixed to the upper end of the cover plate, and a notch on the ear plate for the connecting screw to be inserted. The connecting screw is inserted into the notch and locked in place by a nut.

[0008] Preferably, in order to improve the wear resistance of the cover plate, a wear-resistant liner is installed on the inner surface of the cover plate. The wear-resistant liner can be made of wear-resistant materials such as ceramics.

[0009] Preferably, the wear-resistant liner is fixed to the inner surface of the cover plate by bolts, the wear-resistant liner is fixed to the inner wall of the feed pipe by bolts, and the wear-resistant liner is fixed to the inner wall of the discharge pipe by bolts.

[0010] Preferably, to assist in opening and closing the cover, a fixed pulley is installed on the outer wall of the feed pipe, and a connecting ring is fixed to the outer surface of the cover. One end of a steel wire rope is tied to the connecting ring, and the other end passes over the fixed pulley. When the cover is closed, pulling the steel wire rope can assist in closing the cover; when the cover is opened, slowly releasing the steel wire rope can make the cover open slowly.

[0011] The beneficial effects of this utility model are as follows: This invention utilizes a cover plate and through-holes at the material discharge point to form a trough capable of storing a small amount of coke. The coke accumulated in the trough covers the cover plate, protecting it from direct impact from the falling material, thereby reducing wear and extending its service life. The wear-resistant liner on the cover plate effectively enhances its wear resistance, and the openable design allows for easy replacement of the liner. Furthermore, the cover plate can be opened to clear blockages in the discharge mechanism. Attached Figure Description

[0013] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0014] like Figure 1-4As shown, this utility model includes a feeding mechanism for receiving material falling from a conveyor belt. The feeding mechanism includes a vertically arranged feed pipe 1, an inclined guide pipe 2, and a vertically arranged discharge pipe 4. The feed pipe 1, guide pipe 2, and discharge pipe 4 are connected sequentially by welding. Coke falling from the upper conveyor belt enters the feed pipe 1, passes through the guide pipe 2, enters the discharge pipe 4, and is discharged onto the lower conveyor belt. Wear-resistant liners 3 are installed on the inner walls of both the guide pipe 2 and the discharge pipe 4. A through hole 5 is provided on the lower wall of the guide pipe 2 at a position corresponding to the coke falling point. A cover plate 6 is installed on the outer wall of the guide pipe 2 to cover the through hole 5 and can be opened and closed. The cover plate 6 blocks the through hole 5, forming a material trough for storing coke at the through hole 5.

[0015] In this embodiment, the lower end of the cover plate 6 is hinged to the outer wall of the guide tube 2, and the upper end of the cover plate 6 is connected to the outer wall of the guide tube 2 through a connector. The connector includes a connecting screw 10 fixed to the outer wall of the guide tube 2, and an ear plate 8 is fixed to the upper end of the cover plate 6. The ear plate 8 is provided with a notch 9 for the connecting screw 10 to be inserted. The connecting screw 10 is inserted into the notch 9 and locked and fixed by a nut.

[0016] In this embodiment, in order to improve the wear resistance of the cover plate 6, a wear-resistant liner 3 is installed on the inner surface of the cover plate 6. The wear-resistant liner 3 can be made of wear-resistant materials such as ceramics.

[0017] In this embodiment, the wear-resistant liner 3 is fixed to the inner surface of the cover plate 6 by bolts, the wear-resistant liner 3 is fixed to the inner wall of the guide pipe 2 by bolts, and the wear-resistant liner 3 is fixed to the inner wall of the discharge pipe 4 by bolts.

[0018] In this embodiment, to assist in opening and closing the cover plate 6, a fixed pulley 11 is installed on the outer wall of the feed pipe 1, and a connecting ring 12 is fixedly connected to the outer surface of the cover plate 6. One end of the steel wire rope 7 is tied to the connecting ring 12, and the other end passes over the fixed pulley 11. When the cover plate 6 is closed, pulling the steel wire rope 7 can assist in closing the cover plate 6. When the cover plate 6 is opened, the cover plate 6 can be slowly opened by slowly releasing the steel wire rope 7.

[0019] In actual use, the coke entering the feed pipe 1 will fall into the feed trough. After the coke fills the feed trough, it will slide along the guide pipe 2 and enter the discharge pipe 4. The coke accumulated in the feed trough will cover the cover plate 6, protecting the cover plate 6 from direct impact from the falling material, thereby reducing the wear of the cover plate 6 and extending its service life.

[0020] This invention utilizes a cover plate 6 and a through hole 5 at the material discharge point to form a trough capable of storing a small amount of coke. The coke accumulated in the trough covers the cover plate 6, protecting it from direct impact from the falling material, thereby reducing wear and extending its service life. The wear-resistant liner 3 on the cover plate 6 effectively improves its wear resistance. Furthermore, the cover plate 6's opening mechanism allows for easy replacement of the wear-resistant liner 3. Additionally, in case of blockage in the feeding mechanism, the cover plate 6 can be opened to clear the blockage.

[0021] Of course, the above description is not limited to the examples above.
