Description

Technical Field

[0001] The utility model belongs to the technical field of the safety of the ladle drawing operation in front of the industrial silicon furnace, and particularly relates to a rolling device for reducing the friction of the wire rope for ladle drawing in front of the industrial silicon furnace. Background Art

[0002] Industrial silicon, also known as metallurgical grade silicon, is a purified elemental silicon. Due to different raw material structures, it is mainly produced in two categories: chemical grade metallurgical silicon and metallurgical grade silicon. It is mainly used as the main raw material for the production of organosilicon, polysilicon, and monocrystalline silicon, to produce high-purity semiconductor materials, and to prepare alloys (aluminum alloys) with special uses. The main trace elements to be controlled are Fe, AL, and Ca, and different production grades are defined according to their different contents.

[0003] During the smelting process of industrial silicon, due to the use of a rotating furnace body and a multi-tuyere process, the temperature in the ladle drawing area in front of the furnace is high and the turning radius is large. Therefore, the method of using a hoisting wire rope is mostly adopted for ladle drawing. In this operation mode, the wire rope directly drags on the ground, and the friction force of the wire rope is too large, which causes certain damage to the wire rope. At the same time, due to uneven ground or other factors, the wire rope is prone to jamming. After the wire rope is concentratedly stressed, it may cause the wire rope to be broken-stranded or broken, affecting the safe use of the wire rope and the safety of the surrounding operators. Frequent replacement of the wire rope not only increases the labor intensity and safety risk of the operators, but also leads to an increase in the cost of the wire rope. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rolling device for reducing the friction of the wire rope for ladle drawing in front of the industrial silicon furnace, so as to solve the problems of wire rope friction and jamming existing in the ladle drawing operation during the smelting process of industrial silicon.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A rolling device for reducing the friction of the wire rope for ladle drawing in front of the industrial silicon furnace includes symmetrically arranged drum brackets and support rods. The support rods are arranged on the top of the drum brackets, and clamping grooves are arranged at the tops of the support rods. A drum is straddled on the two support rods, and the rotating shafts of the drum are respectively clamped in the clamping grooves.

[0007] In order to further implement the utility model, the clamping groove is an arc matching the rotating shaft. The top of the clamping groove is open, and the height of the clamping groove is greater than the radius of the rotating shaft.

[0008] In order to further implement the utility model, both the drum brackets and the support rods are made of steel structure materials.

[0009] In order to further implement the utility model, the rotating shaft is made of copper material.

[0010] The beneficial effect of the utility model compared with the prior art is as follows:

[0011] During the ladle drawing operation in front of the furnace, the steel wire rope is placed on the drum of the present utility model, changing the movement mode of the steel wire rope from sliding to rolling during the ladle drawing process, reducing the friction and jamming problems during operation, decreasing the probability of the steel wire rope getting frayed and broken, prolonging the service life of the steel wire rope, reducing the usage cost of the steel wire rope. At the same time, during the operation process, personnel do not need to frequently enter the ladle drawing area to check whether there is a jamming problem with the steel wire rope, reducing the safety risk of the operation and improving the intrinsic safety of the steel wire rope operation during the ladle drawing process.

[0012] The present utility model is simple, fast, practical, economical, efficient and has high safety performance. It optimizes the running mode of the steel wire rope from sliding friction to rolling friction, reducing the friction of the steel wire rope during operation and solving the jamming problem existing during the operation of the steel wire rope.
