The utility model has the advantages of reasonable design reliably, can pass through the angle of step motor adjustment shower nozzle blowout water smoke according to the tunnel wind speed that detects, make spun water smoke remain throughout to be a closed water curtain, guarantee that whole tunnel section all is covered by the water smoke, effectively solved because the too big spun dust fall water smoke that leads to of tunnel wind speed is blown away by the wind, realize the all-round dust fall in tunnel, improved dust fall efficiency, improve staff's operation environment.
Description
Technical Field
The utility model relates to a tunnel dust fall technical field especially relates to a closed water curtain formula tunnel dust device.
Background
At present, dust is still one of the main hazards in the mine production and tunnel excavation processes, and high-concentration dust in a tunnel can cause environmental pollution and even has the danger of explosion; in addition, workers are placed in a high-concentration dust working environment for a long time, and inhale productive dust for a long time, so that pneumoconiosis is easily caused. Therefore, it is necessary to reduce the dust concentration in the roadway and improve the working environment of workers by adopting a reasonable technology.
The utility model discloses before, application number is 201520501307X's utility model discloses a coal mine tunnel separates dirt spraying dust removal system, through devices such as heat release light-operated sensor, solenoid valve, electric ball valve and dust concentration sensor, can carry out the dust removal operation of spraying according to the dust concentration control atomizer that detects. However, the spraying device of the dust-separation spraying and dedusting system cannot ensure that the sprayed water mist forms a closed water curtain in the whole roadway section, and particularly in an expansion roadway with high wind speed, dust is easily blown away from the middle of the roadway section where the water mist cannot be sprayed, and dust-reduction dead angles exist.
Therefore, a closed water curtain type roadway dust settling device is needed to be provided, the device can ensure that sprayed water mist forms a closed water curtain on the whole roadway section, and especially in an expansion roadway with high wind speed, dust in the roadway can be reduced in an all-around manner.
Disclosure of Invention
The utility model aims to solve the technical problem that to prior art not enough, provide a closed water curtain formula tunnel dust device, can make spun water smoke form a closed water curtain according to the angle of the big or small adjustment shower nozzle of wind speed in the tunnel, effectively fall except that the dust in the tunnel guarantees staff's operation environment.
The utility model aims at realizing through the following technical scheme: a closed water curtain type roadway dust settling device is characterized by comprising a support frame arranged in a roadway, wherein a rotary sprayer is mounted on the support frame and is connected with a control box through a data line, and the control box is connected with a wind speed sensor through a data line; the support frame is connected with a water source. The rotary sprayer is provided with a stepping motor, the stepping motor is connected with a spray head through a rotating rod, the spray head is provided with a nozzle, and the nozzle is connected with a water pipe; the rotary sprayer is connected with the support frame through a connecting pipe, and the stepping motor is connected with the control box through a data line arranged in the connecting pipe.
Furthermore, in order to enable the device to be matched with the section of the roadway, the size of the support frame is matched with that of the roadway and is in a straight wall semicircular arch shape.
Furthermore, in order to ensure that the sprayed water mist forms a closed water curtain, the support frame is provided with a rotary sprayer every 40-60 cm.
The utility model discloses a theory of operation is: the wind speed sensor that sets up in support frame the place ahead passes through the data line with the wind speed information of monitoring and passes to the control box, and the control box handles the step motor send instruction in the back rotation sprayer with received wind speed information, and step motor passes through the bull stick and drives the shower nozzle rotatory to corresponding angle, and water smoke is followed the nozzle blowout, forms closed water curtain, and then falls to the dust in the tunnel and removes.
The utility model has the advantages that:
(1) the utility model has novel concept and reasonable design, adopts an assembly structure, and is suitable for roadways with different section sizes;
(2) the rotary sprayer of the utility model can adjust the angle of the spray head according to different wind speeds, ensure that the sprayed water mist forms a closed water curtain on the whole tunnel section, and improve the dust fall efficiency;
(3) the utility model discloses a wind speed sensor, step motor adjust to the shower nozzle angle of pairing rotation atomizer, greatly improve the degree of automation of tunnel dust fall.
