Description

Technical Field

[0001] This invention relates to the technical field of electrolysis and smelting processes in hydrometallurgical zinc refining, and specifically to an automatic cathode zinc feeding system and its feeding method. Background Technology

[0002] In the electrolysis and smelting processes of hydrometallurgical zinc production, the raw material used for zinc smelting is cathode zinc, and the equipment used for melting zinc is an industrial frequency cored induction furnace. Before the cathode zinc is added to the furnace for melting, the cathode zinc stack needs to be transported to the furnace charging port by different methods such as hoisting or conveying.

[0003] Currently, after the cathode zinc plates are deposited in the electrolysis process, three methods are generally used to reach the electric furnace charging port: 1. Manual charging, where the electrolysis process is far from the melting and casting process. Generally, a forklift is used to transport the cathode zinc stacks to the storage area. When the electric furnace needs charging, operators use steel wire ropes to thread through the cathode zinc stacks and use a bridge crane (overhead crane) to lift the stacks to the electric furnace charging port. The specific process is: cathode zinc stack → manual forklift transfer → storage area placement → manual steel wire rope threading → overhead crane lifting → manual unloading. This charging method involves many manual steps, is labor-intensive, and has low work efficiency.

[0004] 2. Automated feeding for the electrolysis process located far from the smelting and casting process. Multiple conveyor chains are installed in the smelting and casting production area, providing sufficient storage positions for cathode zinc stacks, along with supporting equipment such as elevators and forklifts. Manual forklifts transport the cathode zinc stacks onto the conveyor chains, where they are conveyed, lifted, and transferred to the electric furnace charging port. This method typically requires at least 7 conveyor chains, approximately 35 to 40 sets, resulting in a large number of devices and a high investment.

[0005] 3. The electrolysis process is located close to the melting and casting process, and the conveyor chain is automatically fed. Due to the short distance, the cathode zinc is directly fed to the electric furnace charging port via the conveyor chain and elevator after it is produced.

[0006] However, how to economically and efficiently feed the cathode zinc when the electrolysis process is far from the smelting and casting process is an urgent problem to be solved in the current hydrometallurgical zinc electrolysis and smelting and casting processes. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic cathode zinc feeding system and feeding method when the electrolysis process is far from the melting and casting process, thereby solving the problems mentioned in the background art.

[0008] The technical solution adopted in this invention is as follows:

[0009] An automatic cathode zinc feeding system includes a shaping machine 2, an AGV automatic forklift 3, a ground conveyor 5, a sensor-weighing conveyor 6, an automatic induction elevator 7, a 230mm high platform conveyor 8, an RGV automatic induction conveying track shuttle 10, a shuttle track 11, an electric furnace charging platform conveyor 12, an automatic pusher 13, and an automatic lifting machine 14. The sensor-weighing conveyor 6 is installed at the front end of the ground conveyor 5, and the automatic induction elevator is installed at the front end of the sensor-weighing conveyor 6. 7. An automatic induction hoist 7 is equipped with a 230mm high platform chain conveyor 8 at its front end. A shuttle car track 11 is installed at the front end of the 230mm high platform chain conveyor 8. An RGV automatic induction conveyor track shuttle 10 is installed on the shuttle car track 11. An electric furnace charging platform chain conveyor 12 is installed in front of the shuttle car track 11. An automatic lifting machine 14 is installed at the front end of the electric furnace charging platform chain conveyor 12. An automatic pusher 13 is installed on the left side of the automatic lifting machine 14. An electric furnace charging port 15 is installed on the right side of the automatic lifting machine 14.

[0010] The shuttle car track 11 is perpendicular to the 230mm high platform conveyor 8, and the shuttle car track 11 is perpendicular to the electric furnace charging platform conveyor 12.

[0011] The feeding method of the automatic zinc cathode feeding system includes the following steps:

[0012] Step 1: The AGV automatic forklift 3 automatically identifies and removes the shaped cathode zinc stack 1 from the shaping machine 2, and automatically selects to place it on the ground conveyor 5 or the ground storage zinc stack station 9.

[0013] Step 2: When the cathode zinc station at the beginning of the ground conveyor 5 is empty, the AGV automatic forklift 3 should first place the cathode zinc stack 1 on the ground conveyor 5; otherwise, it should be placed at the ground storage zinc stack station 9 for storage.

[0014] Step 3: The ground conveyor 5 circulates and transports cathode zinc material to the downstream process. When the ground conveyor 5 is short of material, the AGV automatic forklift 3 automatically takes the cathode zinc stack 1 from the ground zinc stack station 9 and places it on the ground conveyor 5, automatically identifying and replenishing the material.

[0015] Step 4: The electric furnace charging system and the casting system respond automatically. When the electric furnace needs to be charged, the entire charging system automatically senses and starts.

[0016] Step 5: The cathode zinc stack 1 is conveyed from the ground by the ground chain conveyor 5 to the sensor weighing chain conveyor 6. The chain conveyor 6 automatically weighs the cathode zinc stack using sensors, and the data is transmitted to the casting system. The automatic induction elevator 7 automatically opens its protective door upon detecting the presence of material, and the cathode zinc stack 1 is conveyed to the chain conveyor inside the automatic induction elevator 7. The chain conveyor and the cathode zinc stack are lifted together from the ground to a platform at a height of 230mm. The chain conveyor 8 on the 230mm platform moves, conveying the cathode zinc stack 1 to the shuttle track 11. The RRGV automatic induction conveyor track shuttle 10 detects the cathode zinc stack 1 and automatically shuttles it, conveying the cathode zinc stack 1 to the electric furnace charging platform chain conveyor 12. The electric furnace charging platform chain conveyor 12 conveys the cathode zinc stack 1 to the automatic lifting machine 14, which then automatically lifts it, and the pusher 13 pushes it in batches to the electric furnace charging port 15 for feeding.

[0017] Step Six: Repeat the above actions continuously for each stack of cathode zinc to complete the automatic feeding of cathode zinc from the ground to the electric furnace charging port.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] This invention solves the problems of excessive manual feeding, high labor intensity, and large investment associated with multiple conveyor chains by setting up a single conveyor chain. This invention features a high degree of automation, high work efficiency, small footprint, and is easy to promote and use. Attached Figure Description
