Description

Technical Field

[0001] The utility model relates to the technical field of zinc ingot processing, in particular to a feeding device for a zinc ingot melting furnace. Background Art

[0002] Zinc is a blue-white metal, brittle at room temperature, but malleable at 100 °C to 150 °C. When the temperature reaches the melting point of zinc, zinc changes from solid to liquid. Zinc has a wide range of applications in industry. For example, in the metallurgical industry, zinc can be used for galvanizing to prevent steel from rusting. In the chemical industry, zinc can be used as a catalyst, reducing agent, etc. In addition, zinc also has important uses in fields such as battery manufacturing and building materials.

[0003] After metallic zinc is extracted from ore and purified, it is made into ingots for convenient packaging and transportation, and then transported to the factory for subsequent processing. At this time, the zinc ingots need to be put into the melting furnace for melting, and then subsequent processing operations are carried out. Since the existing zinc ingots are made with a fixed volume and size, generally, devices such as overhead cranes are used to lift them into the melting furnace. During the lifting process, the zinc ingots need to be tied and untied, and the whole process is rather cumbersome. Moreover, the zinc ingots are relatively large in volume and not easy to melt quickly. In view of the above problems, the utility model provides a solution. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a feeding device for a zinc ingot melting furnace.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A feeding device for a zinc ingot melting furnace includes a conveying frame, a conveyor belt, and a shredding mechanism. The conveying frame is installed on one side of the melting furnace. The conveyor belt is installed on the conveying frame through a driving roller and a driven roller. The driving roller is in transmission connection with a conveying motor. An intermediate roller is arranged inside the middle position of the conveyor belt, and the intermediate roller supports the middle position of the conveyor belt to bulge outwards. A tensioning roller is arranged at the bottom of the middle position of the conveyor belt. The end of the conveyor belt is located above the feeding port of the melting furnace. The shredding mechanism is installed inside the feeding port and is located above the furnace chamber. On the side of the melting furnace opposite to the side where the conveying frame is installed, there is a mounting plate. A rotating motor is installed at the bottom of the mounting plate. One end of the motor shaft of the rotating motor is fixedly connected to one end of a connecting rod, and the other end of the connecting rod is connected to a cover plate. When the rotating motor rotates, it drives the connecting rod and the cover plate to rotate, so that the cover plate can cover the feeding port.

[0007] Further, the shredding mechanism includes a pair of shredding rollers installed on the feeding port of the melting furnace. Gear pairs are installed at the ends of the two shredding rollers, and the gear pairs are in transmission connection with a shredding motor.

Specific Embodiments

[0017] The following further describes the present utility model in detail with reference to the drawings. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] As Figures 1 - 3As shown in the figure, a feeding device for a zinc ingot melting furnace includes a conveying rack 1, a conveyor belt 3 and a shredding mechanism. The conveying rack 1 is installed on one side of the melting furnace 13. The conveyor belt 3 is installed on the conveying rack 1 through a driving roller 4 and a driven roller 5. The driving roller 4 is in transmission connection with a conveying motor 18. An intermediate roller 6 is arranged inside the middle position of the conveyor belt 3. The intermediate roller 6 supports the middle position of the conveyor belt 3 to bulge outwards. A tensioning roller 7 is arranged at the bottom of the middle position of the conveyor belt 3. The functions of the intermediate roller 6 and the tensioning roller 7 can shorten the length of the conveyor belt 3 in the horizontal direction, thereby reducing the floor area of the conveying rack 1. The end of the conveyor belt 3 is located above the feeding port 19 of the melting furnace 13. The shredding mechanism is installed in the feeding port 19 and is located above the furnace chamber 14. On the side of the melting furnace 13 opposite to the installation position of the conveying rack 1, there is an installation plate 15. A rotating motor 16 is installed at the bottom of the installation plate 15. One end of a connecting rod 17 is fixedly connected to the motor shaft of the rotating motor 16, and the other end of the connecting rod 17 is connected to a cover plate 12. When the rotating motor 16 rotates, it drives the connecting rod 17 and the cover plate 12 to rotate, so that the cover plate 12 can cover the feeding port 19.

[0019] Further, as Figure 3 shown, the shredding mechanism includes a pair of shredding rollers 11 installed on the feeding port 19 of the melting furnace 13. Gear pairs 21 are installed at the ends of the two shredding rollers 11. The gear pairs 21 are in transmission connection with a shredding motor 20. Driven by the gear pairs 21, the two shredding rollers 11 roll inwards, and the teeth on the shredding rollers 11 shred the zinc ingots.

[0020] Further, a connecting plate 9 is arranged on the side of the conveying rack 1 close to the melting furnace 13. The connecting plate 9 is provided with a through hole for a screw 10 to pass through. The melting furnace 13 is provided with a threaded hole matching with the screw 10. The connecting plate 9 is fixedly connected to the melting furnace 13 through the screw 10. Among them, the through hole is an elongated hole, which is convenient for the screw 10 to adjust its position up and down to match the threaded hole.

[0021] Further, as Figure 2 shown, transverse anti-slip strips 8 are arranged on the belt surface of the conveyor belt 3. The anti-slip strips 8 can prevent the zinc ingots from sliding during transportation, causing potential safety hazards.

[0022] Further, rollers 2 are installed at the bottom of the conveying rack 1. Preferably, the rollers 2 are universal wheels and are equipped with a self-locking mechanism. By arranging the rollers 2, it is convenient to move the position of the conveying rack 1.

[0023] Further, as Figure 1 shown, a protective sleeve made of rubber material is wrapped outside the tensioning roller 7. When the tensioning roller 7 contacts the anti-slip strip 8, the protective sleeve of the tensioning roller 7 can deform to protect itself, and the conveyor belt 3 works normally.

[0024] Working principle: First, the rotating motor 16 rotates to drive the cover plate 12 away from the feed port 19 of the melting furnace 13. Then, the zinc ingots are fed into the melting furnace 13 from the feed port 19 under the conveyance of the conveyor belt 3. After the feeding is completed, the cover plate 12 closes the feed port 19, the conveyor belt 3 stops feeding, and the melting furnace performs the hot melting operation. After the melting operation is completed, the liquid zinc is discharged, the cover plate 12 is opened, and the above work is repeated to carry out the feeding in the next cycle.

[0025] This specific embodiment is only an explanation of the present invention, and it is not a limitation to the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions according to needs, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
