Environmental protection and energy-saving explosion-proof fan based on water source of underground water tank

Abstract

A spraying environment-friendly energy-saving anti-explosion fan based on a shaft sump water source comprises a water tank substrate; a water wheel device is arranged on the water tank substrate and is connected with a wind wheel device by a belt; a high-pressure water spraying device is connected with the water wheel device and the wind wheel device; the technical scheme of taking the shaft sump water source as a power source and combining the functions of wind feeding and spraying of a high-pressure water spraying device, the water wheel device and the wind wheel device is adopted; the defects of high frequency of gas and coal dust explosion caused by electric sparks of a motor, high investment cost, complete demand on the system auxiliary project, large machine noise, poor radiating performance, short service life, low production efficiency, severe production labor environment, easily caused occupational diseases of operation staff and severe coal source waste of the existing coal-mining equipment used for the high-gas shaft are overcome; and the spraying environment-friendly energy-saving anti-explosion fan based on the shaft sump water source is suitable for various ventilation equipment for mine excavation, particularly the ventilation equipment for excavation of the high-gas protruded shaft coal layer.

Description

Technical field [0001] The invention relates to an environmentally friendly, energy-saving and explosion-proof fan based on a spray type of water source in an underground sump. Background technique [0002] At present, in addition to gas explosions, the main factors causing explosions in coal mines are explosions caused by coal dust concentration exceeding the standard. For coal mining in high-gas mines, it is necessary to select equipment with the function of preventing gas explosion, and at the same time perform gas discharge and discharge treatment; while the discharge gas treatment will increase the cost of coal mining a lot, and some mining areas cannot be used due to excessive gas content. When exhausting and discharging gas, we had to give up mining and let the waste of coal resources. For the problem of gas explosion caused by the work of electrical equipment during high gas mine mining, people developed multifunctional fans, dual fans, dual power devices and automatic S...

Problems solved by technology

When mining coal in high-gas mines, it is necessary to select equipment with anti-gas explosion functions, and at the same time do gas extraction and discharge gas treatment; and gas extraction and gas treatment will increase the cost of coal mining a lot, and some mining areas cannot be used due to high gas content. When extracting and discharging gas, they had to give up mining and let the coal resources be wasted; for the problem of gas explosion easily caused by the operation of electrical equipment during mining in high-gas mines, people have developed multi-functional fans, double fans, dual power supply devices and automatic The application technologies such as switching control of gas, wind power blocking, and high-voltage frequency conversion are applied to the mine gas explosion prevention equipment, which has made many technical improvements in the prevention of high gas mine mining, but the relatively mature technology still needs further improvement, and There are also defects such as high investment costs and congruent requirements for system supporting projects; such as high-voltage variable-frequency motor fans, which can automatically adjust the speed of the motor when the underground gas concentration exceeds the standard, so that the wind speed can be accelerated to dilute the gas concentration, thereby reducing the occurrence of explosion accidents. However, when the motor automatically adjusts the speed due to the acceleration of the rotor speed of the motor, the frequency of the gas explosion caused by the electric spark generated by the motor has increased a lot; There is a lot of noise and poor heat dissipation, and it cannot work stably for a long time due to the long distance of air compressed gas transmission, so it can only be used as an auxiliary machine; 3. The dual power supply device needs to have at least two sets of lines for power supply. Next to the substation, the power supply and the dedicated power supply for the fan must not be installed on the same incoming line, otherwise, large-scale power outages will be caused by high-voltage faults
