Problems solved by technology

[0003] At present, when whitening the underground roadway, one method is to manually use a brush or roller brush dipped in paint to whiten the roadway. In the actual work process, the labor intensity is high and the efficiency is low. In addition, during the painting process, the brush and the roadway surface friction contact , the brush wears quickly, and the material waste is serious. Moreover, when manually whitewashing the top of the roadway, the roadway is too high and difficult to operate. Another whitewashing method is to use a pressure tank to spray white. Because it is driven by electricity, it is not suitable for dusty environments. Work, low safety factor
In order to ensure safety, our mine adopts a pedal spray device in the white spraying operation of the underground roadway, which is time-consuming, laborious and inefficient

Embodiment 1

[0037] Such as figure 1 As shown, the pneumatic roadway whitening device includes a pneumatic pump 1, a slurry tank 8, a flow distributor 13 and a backflow stirring device, and the pneumatic pump 1 has a slurry inlet 3 and a slurry outlet 4, and The pulp inlet 3 is connected with a pulp inlet pipe 5, the other end of the pulp inlet pipe 5 extends to the inner bottom of the pulp pool 8, the pulp outlet 4 is connected with a pulp outlet pipe 6, and the other end of the pulp outlet pipe 6 is connected to the flow distributor 13 are connected, and the flow distributor 13 is evenly distributed with a plurality of slurry outlet connection ports 7 connected to its interior, and the slurry outlet connection ports 7 are connected to the spray device, and the flow distributor 13 is also connected with pressure relief and stirring The reflux stirring device has a reflux stirring tube 12, and the other end of the reflux stirring tube 12 extends to the inside of the slurry tank 8; the powe...

Embodiment 2

[0040] A whitening method utilizing the above-mentioned pneumatic roadway whitening device, comprising the following steps:

[0041] Slurry injection: Mix the pre-prepared materials evenly in proportion to form a slurry, and pour it into the mixing tank;

[0042] Boosting and reflux stirring: the air pressure interface 2 of the air pump 1 is connected to the air pressure pipeline set in the roadway, and the air pressure pump 1 is driven by compressed air to inject the slurry in the slurry pool 8 into the In the flow distributor 13, at this time, the pneumatic pump 1 is turned on and the slurry outlet connection port 7 is closed. If the pressure of the slurry in the flow distributor 13 is too high, the pressure relief valve 10 will automatically open, and the excess slurry will pass through the liquid return port. 9 and the reflux stirring tube 12 return to the slurry tank 8, which plays a role in stirring the slurry in the slurry tank 8, and at the same time completes the boos...

Abstract

The invention discloses a pneumatic roadway white spraying device which comprises a pneumatic pump, a slurry pond, a flow distributor and a reverse-flow type stirring device. The pneumatic pump is provided with a slurry inlet and a slurry outlet. The slurry inlet is connected to a slurry inlet pipe while the other end of the slurry inlet pipe stretches to the inner bottom of the slurry pond; the slurry outlet is connected to a slurry outlet pipe while the other end of the slurry outlet pipe communicates to the flow distributor; a plurality of slurry outlet connecting ports communicating to theinner part of the flow distributor are uniformly formed in the flow distributor, the slurry outlet connecting ports are connected to a spraying device, the flow distributor is also connected to the reverse-flow type stirring device which plays pressure relieving and stirring roles, the reverse-flow type stirring device is provided with a reverse-flow type stirring pipe, and the other end of the reverse-flow type stirring pipe stretches into the slurry pond. The invention also discloses a white spraying method by employing the pneumatic roadway white spraying device. The pneumatic roadway white spraying device has the beneficial effects that the pneumatic roadway white spraying device is convenient to use and simple to operate, solves the problem that it is labor-wasting and time-wasting to whiten and it is non-uniform to whiten in the prior art, and is safer and more reliable.

Description

technical field [0001] The invention relates to a wind-driven roadway whitening device and a whitening method using the wind-driven roadway whitening device, belonging to the technical field of roadway construction equipment. Background technique [0002] Non-coal underground mines in the prior art generally use white cement and 107 glue, mixed in a ratio of 10:1 as a white spray paint, although the cost is low and the water resistance is good. [0003] At present, when whitening the underground roadway, one method is to manually use a brush or roller brush dipped in paint to whiten the roadway. In the actual work process, the labor intensity is high and the efficiency is low. In addition, during the painting process, the brush and the roadway surface friction contact , the brush wears quickly, and the material waste is serious. Moreover, when manually whitewashing the top of the roadway, the roadway is too high and difficult to operate. Another whitewashing method is to use...
