Abstract
The invention discloses a hydrocyclone unit used in mine and metallurgy production, in particular to a configuration structure of a hydrocyclone unit used in a grinding system in Bayer alumina production. The structure is as follows: a feeding pipe of each hydrocyclone is connected with a main feeding pipe, an overflow pipe of each hydrocyclone is connected with a main overflow pipe, and an underflow pipe of each hydrocyclone is connected with an underflow trough. The configuration structure has a simple and reliable working principle, adopts the linear configuration of hydrocyclones, and prevents the problem of too large occupied area in the central feeding and the circular configuration of the hydrocyclones by increasing the configuration length. In the configuration method, only one feeding pipe, one overflow pipe and one underflow pipe are connected with the hydrocyclone unit, thereby greatly reducing the number of pipes in production, and facilitating the reduction of the labor intensity in production operation and repairing.
Description
Technical field
The present invention relates to the hydrocyclone group in mine and metallurgical production, relate in particular to the configuration structure of the hydrocyclone group that grinding system uses in a kind of Bayer process alumina producing.
Background technology
The mode of the one section closed circuit classifying grinding of employing that has in the original production system of alumina producer grinds bauxite, be that bauxite grinds into raw ore slurry by ball mill, raw ore slurry delivers into by pump and carries out classification in the hydrocyclone, the overflow of hydrocyclone is sent into next production workshop section as qualified ore pulp, and the hydrocyclone underflow returns ball mill to be continued to grind.Adopt many small grinder ore grindings in the production, every table grinder all is equipped with a hydrocyclone, and production capacity is low.
The production procedure that has is adopted " ball-excellent two stage grinding " production model in order to improve production capacity.After promptly the ore pulp that grinds of one section ball mill entered hydrocyclone, overflow was sent into next production workshop section as qualified ore deposit ore pulp, and underflow enters the next stage rod mill to be continued to grind, and was used for smooth pulp granularity.
Certain primary grinding system of enterprise can adopt 9 table grinders, and the secondary grinding system adopts 2 rod mill productions.Because the ore pulp amount that enters two sections rod mills is excessive, so the separate unit hydrocyclone can not finish production task, needs original many Φ 800 hydrocyclones are formed the use of cyclone group.
Owing to limited by production site, the hydrocyclone group of present central feeding, ring-like configuration can't be used.
Summary of the invention
In order to solve the problems of the technologies described above the configuration structure that the invention provides a kind of hydrocyclone group, purpose is to guarantee that hydrocyclone group production capacity reduces floor space simultaneously, adapts to the alumina producer transformation, puies forward the demand of product.
For reaching above-mentioned purpose, the present invention is achieved in that a kind of configuration structure of hydrocyclone group, its structure is as follows: the feed pipe of each hydrocyclone links with the charging house steward, the overflow pipe of each hydrocyclone is connected with the return main, and the underflow pipe of each hydrocyclone links with the underflow chute.
Described each hydrocyclone is a step configuration.
Described each hydrocyclone is a straight line.
Described each hydrocyclone is installed on the same operating platform.
Described return main and charging house steward all are installed in the pipe holder by the 2%-4% gradient.
Described pipe holder is connected with operating platform.
The end that relative altitude is high among the described return main is equipped with blind plate, and the end that relative altitude is low is connected with overflow pipe in the production system.
The end that relative altitude is high among the described charging house steward is equipped with blind plate, and the end that relative altitude is low is connected with cyclone feed pipe in the production system.
Described underflow chute is pressed the 2%-4% gradient and is installed, and it is by on supporting leg connection and ground or the floor.
Described underflow chute is the square chute that has lid.
Advantage of the present invention and effect are as follows: a kind of hydrocyclone configuration set method operation principle is simple, reliable.The present invention adopts the ladder line configuration of hydrocyclone, has avoided taking up an area of in hydrocyclone central feeding, the ring-like configuration excessive problem in the mode that increases configured length.In this collocation method, the feed pipe, overflow pipe and the underflow pipeline that are connected with this hydrocyclone group all have only one, have alleviated the number of tubes in producing greatly, help alleviating the labour intensity in production operation and the maintenance.

The specific embodiment
Below description by the specific embodiment the present invention is described in further detail; but this can not be used to limit protection scope of the present invention; those skilled in the art are according to basic thought of the present invention; can make various modifications or improvement; but only otherwise break away from basic thought of the present invention, all within the scope of the present invention.
A kind of hydrocyclone configuration set of the present invention structure, wherein each hydrocyclone 5 adopts straight line or ladder to arrange that each hydrocyclone is installed on the same operating platform 4.On the overflow pipe 7 of each hydrocyclone 5 valve 6 is installed; Valve 9 is installed on the feed pipe 8.The overflow pipe 7 of each hydrocyclone 5 all is connected with return main 1; The feed pipe 8 of hydrocyclone 5 all is connected with charging house steward 2; The underflow pipe of hydrocyclone 5 all is connected with underflow chute 3.
Above-mentioned return main 1 all is installed in the pipe holder 10 by the 2%-4% gradient with charging house steward 2, and pipe holder 10 is connected with operating platform.The end that relative altitude is high among the return main 1 is equipped with blind plate, and the end that relative altitude is low is connected with overflow pipe in the production system.The end that relative altitude is high among the charging house steward 2 is equipped with blind plate, and the end that relative altitude is low is connected with cyclone feed pipe in the production system.Underflow chute 3 is pressed the 2%-4% gradient and is installed, and it is by on supporting leg connection and ground or the floor.Underflow chute 3 is for having the square chute of lid.
Principle of the present invention is as follows: use the charging house steward to connect the feed pipe of each hydrocyclone, use the return main to connect the overflow pipe of each hydrocyclone, use discharging chute to compile the underflow of hydrocyclone.With many hydrocyclone step configuration, straight line.
