By robotization means, real-time adjustment is made according to the grade change of technological parameter of pan feeding ore pulp ash content, concentration, flow and granularmetric composition and concentrate, mine tailing ore pulp ash, realize floatation process medicament automatically to add, for guaranteeing that floating product qualified, reduction reagent consumption amount are most important.
Summary of the invention
The technical problem to be solved in the present invention is, for artificial dosing mechanism above shortcomings, a kind of intelligent flotation reagent quantitative add-on system is provided, it makes real-time adjustment according to the grade change of technological parameter of pan feeding ore pulp ash content, concentration, flow and granularmetric composition and concentrate, mine tailing ore pulp ash, realize floating agent and add robotization, intellectuality, improve the degree of accuracy of floating agent addition and significantly improve flotation efficiency.
The present invention for solving the problems of the technologies described above adopted technical scheme is: a kind of intelligent flotation reagent quantitative add-on system, comprising: high-order medicine-chest, solenoid valve, low level medicine-chest, liquid level gauge, electric control valve, medicament impact damper and the intelligent controller to feedback signal process and control.High-order medicine-chest by solenoid valve and pipeline communication to low level medicine-chest, low level medicine-chest establishes high and low liquid level to limit, liquid level gauge is placed in low level medicine-chest, for detecting the high and low liquid level restriction of floating agent, be connected with the medicament impact damper in downstream with pipeline by electric control valve bottom low level medicine-chest, medicament impact damper is by pipeline communication to ore pulp pretreatment system and floatation system, and solenoid valve, liquid level gauge, electric control valve are all connected with intelligent controller by wired mode.
Described intelligent flotation reagent quantitative add-on system adopts intelligent controller to be control core, and it comprises power module, CPU module, digital quantity input/output module, analog input/output module and communication module.Adopt programmable memory, for its internally stored program, actuating logic computing, sequential control, regularly, counting and the function such as arithmetical operation.
Power module, for providing power supply for intelligent controller.
CPU module, in the use procedure of intelligent flotation reagent quantitative add-on system, gathers the live signal of digital quantity input and Analog input mModule, is converted to sample parameter and carries out program computation analysis.
Digital quantity or analog input/output module, for in the use procedure of intelligent flotation reagent quantitative add-on system, the liquid level signal of liquid level gauge in Real-time Collection low level medicine-chest, and after being processed by CPU module by the signal of collection, convert the switch of action command Controlling solenoid valve to; The detection signal of Real-time Collection pan feeding ore pulp ash content, concentration, flow and granularmetric composition and concentrate, tailings ash content detection signal, the signal of reception is calculated by the automatic analysis of CPU module the dosage and the medicine ratio that obtain floating agent, and is converted to the aperture that analog signals controls electric control valve.
Communication module, in the use procedure of intelligent flotation reagent quantitative add-on system, realizes remote monitoring.
Communication is realized by core bus connected mode between described each module.
By such scheme, intelligent controller is used for the liquid level signal of automatic reception liquid level gauge, when detecting lower than low liquid level in limited time, intelligent controller sends action command, and solenoid valve is opened automatically, when detecting higher than high liquid level in limited time, intelligent controller sends action command, and solenoid valve cuts out automatically.
By such scheme, intelligent controller is used for automatic reception pan feeding ore pulp ash content, concentration, the detected value of flow and granularmetric composition and concentrate, mine tailing ore pulp ash content detected value, calculated the dosage and the medicine ratio that obtain floating agent by CPU module automatic analysis, and be converted to the aperture that analog signals controls electric control valve.
Preferably, high-order medicine-chest exit installs additional and is not less than 100 object screen packs to prevent the impurity particle blocking pipeline in floating agent.
Preferably, medicament impact damper is established in the downstream of electric control valve, meets coal slime flotation medicament thickness, requirement that flotation machine only needs the even dosing of trace.
The present invention brings following beneficial effect: floatation process medicament adds automatically, in real time, and pharmaceutical quantities accurately controls, and dosing is economized, and low level medicine-chest realizes the high and low level sensing of medicament, warning and medicament and automatically adds.Simultaneously can according to pan feeding ore pulp ash content, concentration, flow and granularmetric composition and concentrate pulp ash content, the change of mine tailing ore pulp ash content is online regulates in real time, efficiently solve traditional artificial defect such as dosing mechanism poor accuracy, response lag etc., guarantee that floatation clean coal ash content is qualified, tailings ash content is as far as possible high.
