6. Transfer frame spray mode; fully mechanized mining face automatic sprinkler dust removal device;

7. Random hydro-electric linkage spray mode for mining.

The above rich working modes can be adapted to various application scenarios to achieve the dust removal effect.

The mine automatic spray sprinkler dust removal device adopts an explosion-proof and essential safety type structure and is mainly used in coal mine inlet and return air roadways, mining face inlet and return air roadways, car yards, coal bunkers, and other work places requiring regular spray dust removal or regular sprinkling to purify wind flow, the working environment, dust, and protect workers' health.

Characteristics of the ZCYS-127 mine shearer dust source tracking and dust removal system 

1. Through the control panel on the control device, you can arbitrarily set the number of daily sprays and spray duration according to the 24-hour time standard, and the set parameters are observed through the display screen on the device.

If you set 10 watering times a day, the start time of one watering is 8:00; if you need to spray for 5 minutes, the end time of one watering is set at 8:05. The start time of the second watering is 10:20; if it needs to be sprayed for 30 minutes, the end time of the second watering is set at 10:50; and so on.

2. In the process of timing spray or spraying, if the personnel pass through the spray point, under the action of the light control sensor, the control device automatically suspends or delays the spray. The pause (or delay) time can be adjusted, and the personnel can resume spraying or spraying.

3. The timing clock circuit of the dust removal device uses a battery power supply (battery compensation time ≥1 year), and the underground power failure has no impact on the device setting. After the power supply is restored, the device will work according to the original parameters.

4. The use of artificially set timing spray improves the efficiency of sprinkling and dust removal facilities and avoids roadway water accumulation and underground roadway environmental conditions.

Mine Shearer Dust Source Tracking and Dust Removal System  

Introduction to mine shearer dust source tracking and dust removal system

The dust source tracking and dust removal system of a mining shearer is mainly used in the work place where there is a lot of dust in fully mechanized mining work, and it is a convenient and practical ideal dust prevention equipment. The equipment has a high dust collection rate, a good dust removal effect, less water consumption, and high system management.

The system includes an upper computer, main control box, sub-control box, coal discharge external electric ball valve, wireless pressure sensor, infrared transmitter, infrared receiver, remote control, spray device, and other main components. Through the wireless pressure sensor (or wired touch sensor), it achieves shearer tracking, shifting detection, coal discharge detection, and other functions. When the shearer is working, moving, or discharging coal, the trigger sprinkler signal is detected by the wireless pressure sensor, infrared transmitter, and infrared receiver and sent to the sub-control box, which opens the sprinkler or controls the external ball valve spraying water curtain to achieve the function of spraying dust. The system can also communicate with the host computer through RS485 or Ethernet, display information such as the number of spray channels, the current position of the moving frame, and the position of coal discharge in the host computer software, and remotely control the spray state of the underground system.

The dust source tracking and dust removal system of the mining shearer makes it convenient to realize one or more sets of one spray, intelligent dust detection, automatic completion of coal scanning, shifting, and top coal dust removal work. Each parameter can be set on a master or host computer in a unified batch, making it easy for staff management. The sub-control box can also be connected to an external mining lamp as coal-face lighting.

Working principle of the mine shearer dust source tracking and dust removal system 

When the shearer moves, a signal is generated by scanning the infrared receiver mounted on the hydraulic support with an infrared transmitter mounted on the shearer. The signal is fed back to the sub-control box of the spray device, and the sub-control box automatically controls the water supply of the electric ball valve to realize the scanning spray of the bracket coal machine. When moving the frame, the hydraulic handle is operated, and the moving frame sensor (wireless pressure or wired touch sensor) emits trigger signals. After receiving the moving frame signal, the sub-control box opens the built-in electric ball valve and performs spray dust removal work. After the signal disappears, the ball valve automatically enters the delayed lock, and the ball valve automatically closes after the delay, and the dust removal work is automatically completed. When the top coal is discharged, the hydraulic handle is operated, and the coal discharge sensor (wireless pressure or wired touch sensor) emits trigger signals. After the sub-control box receives the top coal discharge signal, the external electric ball valve is controlled to open, and the dust spraying work is performed. After the signal disappears, the ball valve automatically enters the delayed lock, and the ball valve automatically closes after the delay is over, and the coal discharge and dust removal work is automatically completed.
