Abstract

The invention discloses a mining automatic atomizing and dust falling device, relating to a pneumatic control device. One end of a water pressure pipe is connected with a water source, the other end of the water pressure pipe is connected with a booster pump through a filter, and the booster pump is connected with a spray nozzle through a water pipe; and the filter is controlled by the pneumatic control device, the pneumatic control device and the booster pump are connected with an air supply processor through an air pressure pipe, the air supply processor is connected with an air source through the air pressure pipe, an electric ball valve is arranged on the air pressure pipe, the electric ball valve is controlled by a host machine, the host machine is connected with two sensors, and the two sensors are respectively arranged on two ends of a working surface. The mining automatic atomizing and dust falling device has the beneficial effects that the device is simple in design and lower in cost, and the requirement of controlling the mining automatic atomizing and dust falling device through an electric sensing control system during a temporary passing-by can be met. The device has the advantages of convenience in use, low fault rate in continuous operation, excellent atomizing effect, durability, and safety.

Description

technical field [0001] The invention relates to a pneumatic control device, and furthermore is a control device for temporary passage of mine spray dust removal equipment. Background technique [0002] Mine spray dust suppression equipment is used in coal mine inlet (return) air lanes, mining face inlet (return) air tunnels, car yards, coal bunkers and other workplaces that require regular spraying or watering. It can purify the air flow and prevent Dust diffusion and explosion, reducing gas concentration, increasing air oxygen content, improving the working environment, and protecting the health of workers. During its normal work, when people pass through the spray point, the water system of the spray equipment must be closed in time, and the water system of the spray equipment must be turned on after the personnel pass through. In the prior art, there are two types of mechanical control and photoelectric sensor control, but to varying degrees there are defects such as com...
