Description
Technical Field
The invention relates to the technical field of automatic coal mining, in particular to an emulsion concentration on-line monitoring proportioning system.
Background
At present, emulsion concentration monitoring proportioning systems used in coal mine wells generally comprise the following two systems:
mechanical form proportioning system: the main part of the system is a proportional valve, water and emulsified oil are connected into the proportional valve, and the flow of the water and the emulsified oil is controlled by adjusting the proportional valve.
The disadvantages are as follows: the concentration of the emulsion in the system can not be dynamically adjusted, the concentration on-line monitoring function is not realized, the concentration can only be manually monitored, and the proportional valve is required to be frequently adjusted. The flow of the inlet water is extremely unstable, so that the concentration of the emulsion prepared by the proportional valve is not guaranteed, and special personnel is required to take care of the emulsion.
Simple on-line monitoring proportioning system: the system mainly comprises a concentration sensor, an emulsion oil pump, a water inlet electromagnetic valve, a liquid mixer and a controller. The emulsion oil pump is a fixed displacement pump, and the water inlet electromagnetic valve and the emulsion oil pump are simultaneously opened and closed.
The disadvantages are as follows: the readings from the concentration sensor are only displayed and are not involved in the control, so that dynamic adjustment of the emulsion concentration in the whole system is still impossible. Because the flow of the inlet water is an extremely unstable value and the corresponding matched emulsion oil pump is a fixed displacement pump, the accuracy of the concentration of the emulsion from the liquid mixer is difficult to ensure, and the aim of unattended operation cannot be achieved even if the emulsion from the liquid mixer is not fine-tuned.
