Intelligent emulsion pump station for mining

Abstract

The mining intelligent emulsion pumping station belongs to coal mining safety production equipment, including an emulsion tank, an emulsion pump, an emulsion pipeline, and an emulsion pumping station controller. It is characterized in that: the emulsion pumping station controller includes a main control circuit, auxiliary control circuit and PLC programmable controller system control circuit, pressure sensor (8), liquid level sensor (14), concentration sensor (15), oil level sensor (18), emulsion tank are installed A temperature sensor (5), a pressure sensor (8), a liquid level sensor (14), a concentration sensor (15), an oil level sensor (18), and a temperature sensor (5) are installed on the pump (25). station controller connection. The pumping station adopts constant pressure and variable liquid supply, variable frequency speed regulation, intelligent control, automatic switching between the two pumps, automatic control of liquid level and oil level, automatic monitoring of emulsion pump temperature, safety pressure relief protection, automatic liquid distribution, and improved The service life of the hydraulic support highlights the explosion-proof safety of the coal mine underground, the working performance is reliable, and the operation of the pump station is economical and energy-saving.

Description

technical field [0001] An intelligent emulsion pumping station for mines belongs to safety production equipment for coal mining, and specifically relates to an intelligent emulsion pumping station for mining used in supports for mining in coal mines. Background technique [0002] Coal is my country's basic energy and an important raw material for various industries. In recent years, with the rapid development of the national economy, coal products have grown rapidly. How to ensure the reliability, safety, energy saving and consumption reduction of mining equipment, and meet the requirements of environmental protection is the guarantee An important part of the sustainable development of the coal industry, the main problems existing in the mining emulsion pump station at present are that the control process cannot be intelligent, the power consumption is large, and the hydraulic system cannot automatically release the pressure when it is shut down for maintenance, which increase...

[0002] Coal is my country's basic energy and an important raw material for various industries. In recent years, with the rapid development of the national economy, coal products have grown rapidly. How to ensure the reliability, safety, energy saving and consumption reduction of mining equipment, and meet the requirements of environmental protection is the guarantee An important part of the sustainable development of the coal industry, the main problems existing in the mining emulsion pump station at present are that the control process cannot be intelligent, the power consumption is large, and the hydraulic system cannot automatically release the pressure when it is shut down for maintenance, which increases the inconvenience of equipment and personnel. Safety factor, the liquid pump does not have a temperature monitoring device, which is easy to cause damage to the liquid pump. When the liquid pump fails, it cannot automatically switch to another liquid pump. The emulsion dosing is manually operated, resulting in inaccurate emulsion concentration during use, shortening the The service life of the hydraulic support, the inaccurate liquid level alarm, and the inability to work in conjunction with the control system can no longer meet the higher demand for coal mining equipment in today's society
