Problems solved by technology
[0004] Disadvantages: It is impossible to dynamically adjust the concentration of the emulsion in the system, and it does not have the function of online monitoring of the concentration. The concentration can only be monitored manually and the proportional valve needs to be adjusted frequently
[0006] Disadvantage: The reading of the concentration sensor is only displayed and not involved in the control, so it is still impossible to dynamically adjust the emulsion concentration in the entire system
Since the flow rate of the water inlet is an extremely unstable value, and the corresponding emulsified oil pump is a quantitative pump, it is difficult to guarantee the accuracy of the concentration of the emulsified liquid coming out of the mixer, let alone the possibility of fine-tuning. To achieve the purpose of unattended

The invention relates to an on-line monitoring and proportioning system of emulsion concentration, and relates to the technical field of automatic coal mining. The work of the whole system of the present invention is controlled by the PLC in the proportioning control box, and the water inflow and oil inflow of the system are accurately measured by the emulsified oil flowmeter and the water inflow flowmeter, and the emulsion of the pump station is controlled at the source The concentration of the emulsion in the tank; and through the online monitoring function of the emulsion concentration sensor, the emulsion concentration in the mixing tank and the emulsion tank of the pump station is mastered in real time, and the value is transmitted to the proportioning control box in real time, and the proportioning control The PLC in the tank can control the injection of water or oil into the mixing tank and the emulsion tank of the pump station at any time through judgment, calculation and comparison to complete the fine adjustment of the concentration of the emulsion.
Description
technical field [0001] The invention relates to the technical field of automatic coal mining, in particular to an emulsion concentration online monitoring ratio system. Background technique [0002] At present, there are generally two types of emulsion concentration monitoring and proportioning systems used in underground coal mines: [0003] Mechanical proportioning system: The main part of the system is a proportional valve, which connects water and emulsified oil to the proportional valve, and controls the flow of water and emulsified oil by adjusting the proportional valve. [0004] Disadvantages: It is impossible to dynamically adjust the concentration of the emulsion in the system, and it does not have the function of online concentration monitoring. It can only monitor the concentration manually and needs to adjust the proportional valve frequently. Since the flow rate of the incoming water is extremely unstable, the concentration of the emulsion prepared by the prop...
