Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention equipment in steel plants, in particular to a horizontal charging vibration device for an electric furnace in a steel plant with a protective structure. Background Art

[0002] With the development of steelmaking industry, the safety and stability of the horizontal charging system of electric furnaces have become increasingly important. To this end, we have developed a horizontal charging vibration device for electric furnaces in steel plants with a protective structure. The main function of this device is to protect the equipment and personnel in the electric furnace from accidents and dangerous substances. The structure of the device mainly consists of three parts: the upper part is a horizontal charging platform for placing the materials to be heated; the middle part is a vibration generator, which transmits the vibration to the electric furnace in the lower part through rotation, speed change and orientation; the lower part is the part directly connected to the electric furnace, which is used to connect and guide the vibration. The shell of the entire device is made of high-strength metal material with good wear resistance and impact resistance.

[0003] The existing protective structure of the steel plant electric furnace horizontal charging vibration device has the problem of lubricating oil leakage in the tail and middle bearing seal areas when in use. After in-depth investigation and research, it was found that the main reason is that the dust content in the working area is too high, which makes it easy for dust to enter the bearing seal area, causing shaft seal wear and thus lubricating oil leakage. Severe shaft seal wear may even cause bearing damage, and also contaminate the lubricating oil, affecting the normal operation and use of the equipment. More importantly, due to the excessive dust in this area, maintenance work has become very difficult, increasing maintenance costs and equipment downtime.

[0004] Therefore, it is necessary to provide a new steelmaking plant electric furnace horizontal charging vibration device with a protective structure to solve the above-mentioned technical problems. Utility Model Content
