Description

[0002] When mining, blasting and other operations are carried out in the mine shafts of mines, a large amount of dust is often generated and dispersed in the air, seriously reducing the quality of people's working environment and affecting the health of workers. Therefore, dust suppression devices are often used in mine shafts to reduce the dust content in the air.

[0003] In the prior art, a Chinese patent with publication number CN116856991A discloses a mining spray fan, including a control box, a mounting frame, a fan and a lifting assembly; however, this technical solution still has the following problems: (1) Mining blasting will generate a large amount of respirable dust. This technical solution uses high-pressure water mist to reduce dust. Since the inertia of respirable dust is small, it is easy to bypass the droplets after colliding with the water mist, and the dust reduction effect is poor; (2) This technical solution can only adjust the height of the spray fan, and cannot make the spray fan swing left and right to reduce dust, and its use is relatively limited; (3) There is no dustproof plate at the air inlet of the air duct, and the dust and other impurities sucked in by the wind pressure generated by the fan will affect the performance of the internal equipment.

[0098] To further optimize the solution, an ultrasonic water level measuring instrument 37 is installed on the inner wall of the liquid distribution tank 29; the ultrasonic water level measuring instrument 37 is electrically connected to the control element 51; with this arrangement, the liquid level of the dust reduction liquid in the liquid distribution tank 29 is monitored by the ultrasonic water level measuring instrument 37 to ensure the normal operation of the planetary gear set.

[0099] To further optimize the solution, an impurity filter is installed at one end of the liquid inlet pipe 47 extending into the liquid distribution box 29; in this way, impurities in the dust reduction liquid are filtered out by the impurity filter to prevent impurities from clogging the nozzle 4, thereby ensuring the stability of the fog cannon's spray dust reduction work.

[0100] Further optimized solution, the up and down swing assembly includes a mounting seat, a pulling block and an electric push rod 13; the mounting seat is installed on the top of the rotating disk 14; the pulling block is installed at one end of the cylinder 1 close to the nozzle ring 2; the rod end of the electric push rod 13 is hinged to the mounting seat, and the telescopic end of the electric push rod 13 is hinged to the pulling block; the electric push rod 13 is electrically connected to the control element 51;

[0101] With such arrangement, the output rod of the electric push rod 13 is extended or retracted, so that the two ends of the fog cannon are alternately raised, and then the fog cannon is swung up and down, thereby expanding the coverage of the spray and making the spray operation of the fog cannon more comprehensive and without dead ends, and being able to meet the use requirements in different situations; by adjusting the output power and time of the electric push rod 13 through the control element 51, the swing frequency and duration of the electric push rod 13 can be changed, thereby increasing the flexibility of use.
