Abstract
The utility model relates to a lining, in particular to a lining structure of an ore feeding room in alumina ore coarse crushing, which protects the ore feeding room when a feeding room in a reinforced concrete structural form and alumina ores are added into a course crushing room to be coarsely crushed through an ore inlet. The lining structure of the ore feeding room in alumina ore coarse crushing comprises the feeding room, and the lining which is arranged in the feeding room, wherein the lining is a steel rail, the spacing of the steel rail is 150 to 250mm, and the steel rail points to the ore inlet. The lining structure of the ore feeding room in alumina ore coarse crushing has the advantages and effects that when the cores are coarsely crushed and enter the feeding room, the feeding room which adopts the steel rail for lining protection can resist the impact when the ores fall, thereby preventing the feeding room and a feed opening from being damaged under the action of the impact of the ores, prolonging the service life of the feeding room and crushing equipment, making the ores more smoothly enter the crushing equipment, and improving the utilization rate and the productivity of the equipment.
Description
Technical field
The utility model relates to a kind of liner, relates in particular to the feed space splendid attire bauxitic ore with the reinforced concrete structure form, advances the inner lining structure between the ore deposit when protecting the into bauxitic ore coarse crushing between the ore deposit when iron ore feeding hole adds bauxite to coarse crushing between coarse crushing.
Background technology
In the Bayer process aluminum oxide production process, the bauxitic ore that comes from mining is one of main raw materials for production.Because the main reaction of Bayer process stripping is a solid-liquid reaction, this reaction is generally carried out at the surface of solids, in order to improve reaction speed, each the component surface area that requires to participate in chemical reaction wants big, mix and want evenly, just requiring ore must be the fine grained that meets the grinding particle size requirement, but the bauxitic ore that exploitation comes mostly is irregularly shaped, and piece directly differs in size, be difficult to reach the requirement with other raw material generation chemical reaction, so need in process of production bauxitic ore with disintegrating apparatus according to coarse crushing, in broken, shattering process finished breaking in small, broken bits becomes to meet the fine grained that grinding particle size requires.Before coarse crushing for the protection disintegrating apparatus earlier drops into feed space with bauxitic ore, through iron ore feeding hole in an organized way, by metering enter into and carry out fragmentation in the coarse crushing equipment.Because feed space mostly adopts the reinforced concrete structure form, when bauxitic ore is dropped into feed space, the sidewall of feed space and base plate can be subjected to strong wallop, and feed space uses a period of time to be easy to be destroyed, thereby influence the service life of disintegrating apparatus; Even adopt steel plate to do liner, but under the strong wallop effect, steel plate can produce distortion, cause that into the ore deposit is obstructed, influence is produced, and has also caused the waste on the material cost.
The utility model content
In order to solve the problems of the technologies described above the inner lining structure that advances when the utility model provides a kind of bauxitic ore coarse crushing between the ore deposit, purpose is to prevent that feed space and charging aperture from being destroyed under the effect of ore impulsive force, prolonged the service life of feed space and disintegrating apparatus, and ore is entered in the disintegrating apparatus more swimmingly, improve usage ratio of equipment and productivity ratio.
For reaching above-mentioned purpose, the utility model is achieved by the following technical solution:
Advance the inner lining structure between the ore deposit during bauxitic ore coarse crushing, comprise feed space, be located at the liner of feed space, wherein liner is a rail, and the spacing of rail is 150～250mm, and the rail direction is pointed to iron ore feeding hole.
Described rail is fixed with the vertical inboard built-in fitting of feed space inboard, the base plate of feed space and the inclined-plane built-in fitting welding at iron ore feeding hole place respectively.
The vertical inboard built-in fitting spacing of described feed space is 150～300mm, and level is arranged along girth.
Dowel on described vertical inboard built-in fitting and the inclined-plane built-in fitting is fixed on the inwall of feed space.
Described vertical inboard built-in fitting and inclined-plane built-in fitting are steel plate, and steel plate thickness is 14～30mm.
Described rail is the crane heavy rail.
The utility model has the advantages of: when the ore coarse crushing enters feed space; impulsive force when the feed space that has adopted rail to do inner lining protection can be resisted ore and falls; can prevent that feed space and charging aperture from being destroyed under the effect of ore impulsive force; prolonged the service life of feed space and disintegrating apparatus; and ore is entered in the disintegrating apparatus more swimmingly, improve usage ratio of equipment and productivity ratio.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail, but protection domain of the present utility model is not limit by embodiment.
As Figure 1-3, advance the inner lining structure between the ore deposit during coarse crushing of the utility model bauxitic ore, comprise feed space 1, be located at the liner of feed space 1, liner is a rail 4, and the spacing of rail 4 is 150～250mm, rail 4 directions are pointed to iron ore feeding hole 8, rail 4 is fixing with inclined-plane built-in fitting 2 welding at the base plate of the vertical inboard built-in fitting 3 of feed space 1 inboard, feed space and iron ore feeding hole place respectively, feed space 1 vertical inboard built-in fitting 3 spacings be 150～300mm, level is arranged along girth; Dowel 9 on vertical inboard built-in fitting 3 and the inclined-plane built-in fitting 2 is fixed on the inwall of feed space, and vertical inboard built-in fitting 3 and inclined-plane built-in fitting 2 are steel plate, and steel plate thickness is 14～30mm, and rail is the crane heavy rail.
When hanging device 7 bauxitic ore 6 is hung feed space 1 directly over the time, hanging device 7 is opened, when bauxitic ore 6 is fallen on the rail 4, can make the ore guiding enter iron ore feeding hole 8,5 pairs of ores of disintegrating apparatus carry out fragmentation, the built-in fitting at the base plate of feed space and iron ore feeding hole place is an integral body, and assurance base plate integral body is born upper load.
