Abstract
The invention relates to a system and method for classifying and storing ore pulp slurry by utilizing concentration, used for classification and storage of first-level ore concentrate and low-grade second-level ore concentrate at terminal dehydration stations of mining enterprises. The system comprises a first-level ore concentrate storage groove, a second-level ore concentrate storage groove, a main electrically operated valve, a standby electrically operated valve, a second-level ore concentration automatic flow inclined pipe, a second-level ore concentration automatic flow pipe, a core concentration main pipeline, a concentration meter and a first-level ore concentration outlet pipeline. The method comprises the following steps: transmitting a concentration value which is measured by the concentration meter to a PLC (programmable logic controller); closing the main electrically operated valve if the second-level ore concentration is confirmed so that the ore pulp flows upwards into the second-level ore concentrate storage groove through the second-level ore concentration automatic flow inclined pipe; and opening the main electrically operated valve if the arrival of second-level ore concentration pulp tail is confirmed or the first-level ore concentration is about to be stored, so that the ore pulp flows downward into the first-level ore concentrate storage groove. According to the invention, the ore pulp at different grades can be subjected to classification storage and hydration operation simply and effectively.
Description
Technical field
The technology of carrying out classification storage and dehydration after the present invention relates in solid material slurry transportation process the multistage ore pulp slurry of line transportation reached terminal, particularly a kind of system and method thereof of utilizing concentration to ore pulp slurry classification storage.
Background technique
In the manufacturing enterprise of mine, exploitation and transportation high grade ore are the top priorities of enterprise always at present, and with respect to exploitation and transportation poor value, this will bring bigger economic benefit.Yet in the face of the continuous rising of ore price, the low-grade ore that leaves the mine periphery in also begins to be transported together with high-grade ore by manufacturing enterprise.Therefore, one-level concentrate and second concentrate are by the hierarchical segmented dehydrating plant that is transported to as the ore terminus of pipeline.Yet the dewatering operation of one-level concentrate and the dewatering operation of second concentrate need separately carry out usually.Moreover, second concentrate, can not be accomplished promptly to take off in view of the principle of reasonableness of producing running because amount is few, that is to say and need store separately second concentrate, just can carry out dehydration work after only reaching the dewatering operation condition.Therefore influenced operating efficiency.
Summary of the invention
The objective of the invention is defective, a kind of system and method that utilizes concentration to ore pulp slurry classification storage is provided at above-mentioned prior art.Use system and method for the present invention, can carry out simple and effective classification storage and dewatering operation different grade ore pulps.
The technological scheme taked of the present invention is for achieving the above object: a kind of system that utilizes concentration to ore pulp slurry classification storage, comprise: one-level concentrate holding tank, the second concentrate holding tank, main electric valve, second concentrate gravity flow inclined tube, the second concentrate gravity line, the concentrate main pipe, densitometer, one-level concentrate outlet conduit, wherein, densitometer is installed on the terminal pipeline of concentrate main pipe; Main electric valve is installed on the one-level concentrate outlet conduit; Be formed with the inclined tube that direction makes progress in the upstream of described main electric valve; One-level concentrate outlet conduit is communicated to one-level concentrate holding tank; The second concentrate gravity line is communicated to the second concentrate holding tank.Also comprise standby electric valve on the described one-level concentrate outlet conduit.Described standby electric valve is in normally open when described main electric valve is worked.A kind of method of utilizing concentration to ore pulp slurry classification storage, comprise: the detected concentration value of densitometer is sent to the PLC controller, and judge whether the mine slurry grade variation and make instruction manipulation, if determine to close main electric valve behind the second concentrate, ore pulp is flowed by second concentrate gravity flow inclined tube bottom-uply and enter the second concentrate holding tank; Arrive in the time of maybe will storing the one-level concentrate if determine second concentrate slurry tail, the described main electric valve of closing is opened, make the ore pulp from top to down flow automatically to one-level concentrate holding tank.Standby electric valve is installed on described one-level concentrate outlet conduit.Described standby electric valve is in normally open when described main electric valve is worked.
The system and method that utilizes the concentration characteristic that multistage ore pulp is carried out the classification storage that the present invention proposes can be according to producing actual demand, the ore pulp of different grades carried out simple and effective classification storage and dewatering operation, thereby enhance productivity.Therefore the present invention is applicable to that bargh stores in the classification of terminal point dehydrating plant one-level concentrate and the not high second concentrate of grade.

Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the concentration of utilizing of the present invention comprises the system of ore pulp slurry classification storage: one-level concentrate holding tank 1, second concentrate holding tank 2, main electric valve 3, standby electric valve 4, second concentrate gravity flow inclined tube 5, second concentrate gravity line 6, concentrate main pipe 7, densitometer 8, and one-level concentrate outlet conduit 9.Holding tank is used to store different grades and other concentrate of level, and one-level concentrate holding tank 1 is used to store the one-level concentrate, and second concentrate holding tank 2 is used for the store secondary concentrate.Densitometer 8 is installed on the terminal pipeline of concentrate main pipe 7, and with interior place, detected concentration value is shown to operator apart from terminal valve 3 or 4 about 50m.Main electric valve 3 is installed on the one-level concentrate outlet conduit 9, a standby electric valve 4 can also be installed, this mainly is to consider that service valve works on when the main valve fault, and this standby electric valve is in normally open.In the front of described valve, promptly the upstream of valve 3,4 is formed with the second concentrate gravity flow inclined tube 5 that direction makes progress, and is used for when valve 3 or 4 is closed the second concentrate ore pulp and enters the second concentrate inclined tube 5 that flows automatically bottom-uply.One-level concentrate outlet conduit 9 is communicated to one-level concentrate holding tank 1.Second concentrate gravity line 6 is communicated to second concentrate holding tank 2.
Working principle: after densitometer 8 is sent to concentration value the PLC of enterprise controller (programmable logic controller (PLC)), determine whether that through a series of judgements back guiding operation personnel mine slurry grade changes (second concentrate arrives or water arrives) and makes instruction manipulation, determine to close main electric valve 3 behind the second concentrate, ore pulp can only flow bottom-uply and enters second concentrate holding tank 2 by the second concentrate inclined tube 5 that flows automatically; When judging that by densitometer 8 second concentrates slurry tails arrive maybe will store the one-level concentrate time, open the main electric valve 3 of closing, the just top-down one-level concentrate holding tank 1 that flows automatically to of ore pulp can not enter second concentrate holding tank 2 by the second concentrate inclined tube 5 that flows automatically.
The present invention only proposes the classification storage principle at the two-stage concentrate, is suitable for the application need of present manufacturing enterprise, certainly, also can adopt this principle to design to three grades of concentrate or level Four concentrate.
