Description

Technical Field

[0001] The present invention relates to the technical field of dust control devices, and in particular to an intelligent adjustable wind curtain dust control device. Background Art

[0002] Mine dust, as one of the "five major mine disasters", has always been widely concerned. With the increasing intensity of coal mining at this stage, the investment of large-scale machinery and equipment has brought more serious dust hazards while increasing production. In the process of mining, the dust generated poses a serious threat to the health and safety of miners and affects the normal service life of equipment. In order to ensure that mine personnel have enough air to breathe, air needs to be delivered to the excavation working face through an air supply device. Air is directly supplied to the excavation working face through air supply fans and air ducts, and the wind flow blows directly to the excavation working face, so that the dust generated by the excavator is blown away and quickly escapes, which is not conducive to the dust reduction operation of the tunnel.

[0003] In addition, the existing air duct cannot adjust the air volume according to the real-time dust concentration, the wind flow is turbulent, and an effective wind curtain cannot be formed to block the dust overflowing head-on, causing the dust to diffuse in the tunnel, making the air in the rear tunnel polluted and the visibility poor.

[0004] Therefore, it is necessary to provide an intelligent adjustable wind curtain dust control device to solve the above technical problems. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an intelligent adjustable wind curtain dust control device that can generate an air curtain wall in the tunnel, which is beneficial to dust reduction operations and can intelligently control the strength of the air curtain wall according to the real-time changes of dust concentration in the tunnel.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.

[0028] Embodiment 1:

[0029] like Figure 1-5As shown, the intelligent adjustable wind curtain dust control device provided by the present invention includes: a dust control mechanism 1 and a control terminal 24 electrically connected to the dust control mechanism 1, and the control terminal 24 is used to control the dust control mechanism 1, so that the dust control mechanism 1 can adjust the air supply according to the real-time dust concentration in the tunnel, and block the dust from escaping to the rear tunnel, thereby achieving the purpose of energy saving, noise reduction, and controlling dust escape. In order to better achieve the above goals, the dust control mechanism 1 needs to be used in conjunction with the spray dust reduction device installed in the tunnel, that is, the dust control mechanism 1 forms an intercepting air curtain wall in front of the dust to intercept the dust, and in front of the air curtain wall, the spray dust reduction device sprays water mist to reduce the dust and reduce the dust content in the tunnel. In this embodiment, the dust control mechanism 1 includes a shell 2, an air inlet pipe 3 is installed at one end of the shell 2, the air inlet pipe 3 is connected to the wind tube, an air outlet pipe 4 is installed on one side of the shell 2, and an air control component is installed on the air outlet pipe 4. An input component 5 is also installed on the shell 2, and the input component 5 is electrically connected to the control end 24 for displaying the operating data of the device and inputting control parameters. The wind control component includes an air curtain generator 6 installed in the air outlet pipe 4 and an air control pipe 7 installed at the front end of the air outlet pipe 4. The air in the wind tube enters the shell 2 through the air inlet pipe 3, and then enters the air curtain generator 6 from the shell 2. The air curtain generator 6 compresses the air and then expands the air to make the air spray out at a higher speed and disperse the air more evenly in the air outlet pipe 4. Then the air control pipe 7 located at the end of the air outlet pipe 4 diverts the high-speed airflow in the air outlet pipe 4, so that the airflow forms an air curtain wall in front of the air outlet pipe 4 to prevent the dust in the tunnel from continuing to move forward. In the actual use of the device, in order to meet the need to block dust, multiple devices can be used, and these devices can be arranged in the same plane of the tunnel, so as to prevent the dust in the tunnel from escaping to the rear, which is convenient for the spray dust reduction device to reduce the dust. At the same time, a first electric control valve 8 is installed on the air inlet pipe 3, and an air volume sensor 9 is installed on the air outlet pipe 4. The air volume sensor 9 is arranged in the air outlet pipe 4 between the air curtain generator 6 and the air control pipe 7. A dust concentration sensor 10 is installed on the shell 2. The electric control valve 8, the air volume sensor 9 and the dust concentration sensor 10 are all connected to the control end 24. The dust concentration sensor 10 is located behind the air outlet pipe 4 and can detect the dust concentration behind the air curtain wall and transmit the result to the control end 24. When the dust concentration behind the air curtain wall is When the degree decreases, the dust concentration sensor 10 transmits the result to the control end 24, and the control end 24 controls the first electric control valve 8 to start, reduce the air intake of the device, reduce the air output of the air outlet pipe 4, and then reduce the strength of the generated air curtain wall. Conversely, the air intake is increased to increase the strength of the air curtain wall. During this period, the air volume sensor 9 monitors the air volume and wind speed data near the outlet side of the air outlet pipe 4 in real time, and transmits the data to the control end 24, and the control end 24 displays the data on the display screen of the input component 5 in real time.Through the above steps, the air output of the intelligent control device can be controlled according to the real-time dust concentration changes in the tunnel to form a stable and controllable air curtain wall, which can more efficiently intercept dust, prevent dust diffusion, and improve dust control efficiency.

[0030] By setting up a dust control mechanism 1 and a control end 24, and setting up a dust control mechanism 1 including a shell 2, an air inlet pipe 3, an air outlet pipe 4, an input component 5, an air curtain generator 6 and an air control pipe 7, an air curtain wall can be generated in the tunnel to block the advancement of dust and facilitate dust reduction operations. The dust concentration is detected by using a dust concentration sensor 10, and the air outlet volume and air curtain wall strength of the intelligent control device can be controlled according to the real-time changes of the dust concentration in the tunnel, thereby more efficiently intercepting dust, preventing dust from spreading, and improving dust control efficiency.

[0031] Embodiment 2:

[0032] like Figure 3-4 As shown, the air curtain generator 6 is provided with a small air inlet 11 and a wide air chamber 12, and a plurality of jet slots 13 are provided on the outlet side of the air curtain generator 6, and the spacing between the plurality of annular jet slots 13 gradually decreases from the inside to the outside, and a plurality of air ducts 14 are provided between the jet slots 13 and the air chamber 12, and the air ducts 14 are used for communicating the jet slots 13 with the air chamber 12. It is worth noting that the outer opening of the air inlet 11 is large and the inner opening is small, and the air enters from the outside of the air inlet 11 and is gradually compressed to improve the airflow. speed, and then the high-speed airflow enters the air chamber 12, the gas volume expands, and then passes through the air duct 14 and is discharged from the jet slot 13. Since the multiple jet slots 13 are distributed in a ring shape, the discharged airflow can be discharged more evenly, and the airflow is more evenly distributed in the air outlet pipe 4. The wind speed at each point is basically the same. If the air curtain generator 6 is not used, the air speed near the center of the air outlet pipe 4 is fast, and the air flow speed near the edge of the pipe wall is slow, and it is difficult to achieve the effect of stabilizing the airflow blowing to the air control pipe 7.

[0033] By arranging the air inlet 11, the air chamber 12, the jet slot 13 and the air duct 14 on the air curtain generator 6, the air can be accelerated, and the direction of the airflow can be controlled to avoid wind flow turbulence.

[0034] Embodiment 3:

[0035] like Figure 5As shown, one end of the air control duct 7 is sealed and connected to the end of the air outlet duct 4, and a transverse guide vane 15 and a longitudinal guide vane 16 are installed on the air control duct 7. The transverse guide vane 15 is driven by a first driver 17 installed at one end thereof. Similarly, the longitudinal guide vane 16 is driven by a second driver 18 installed at one end thereof. In this embodiment, the first driver 17 and the second driver 18 are both small explosion-proof motors or explosion-proof electric push rods. The first driver 17 and the second driver 18 are used to drive the transverse guide vane 15 and the longitudinal guide vane 16 to rotate, thereby adjusting the air outlet direction on the outlet side of the air control duct 7. It is worth noting that the first driver 17 and the second driver 18 are both connected to the control end 24, so that the first driver 17 and the second driver 18 can rotate. Taking the first driver 17 and the second driver 18 as motors as an example, the control end 24 controls the rotation speed and start and stop of the first driver 17 and the second driver 18. When in use, the air discharged through the air curtain generator 6 is guided by the transverse guide wing 15 and the longitudinal guide wing 16, wherein the transverse guide wing 15 makes the air flow injection direction swing up and down, and the longitudinal guide wing 16 makes the air flow injection direction swing left and right. This situation is similar to the air outlet of the air conditioner. Since the transverse guide wing 15 and the longitudinal guide wing 16 are used in conjunction with each other, they can swing back and forth quickly and continuously, so that the air flow is continuously ejected up and down, left and right at one end of the air control pipe 7 (the injection speed is faster), thereby forming an air curtain wall close to a sphere (a part of a sphere).

[0036] By installing transverse guide wings 15 and longitudinal guide wings 16 on the air control duct 7, the airflow is guided by using the transverse guide wings 15 and longitudinal guide wings 16 so that the air sweeps the front end of the air control duct 7, and an air curtain wall can be formed in front of the air control duct 7, thereby controlling the dust and preventing the dust from continuing to move forward.

[0037] Embodiment 4:

[0038] like Figure 2 As shown, in order to reduce noise, sound-absorbing cotton 19 is installed on the air outlet pipe 4 (the sound-absorbing cotton 19 can be installed outside or inside the air outlet pipe 4, and this embodiment takes it as an example of being installed inside). When air flows through the air outlet pipe 4, the sound-absorbing cotton 19 can absorb and reduce the noise inside the device, reduce the noise when the device is running, improve the environmental comfort, and is beneficial to the health of workers working nearby.

[0039] By installing the sound-absorbing cotton 19 in the air outlet pipe 4, the noise during the operation of the device can be reduced, the environmental noise can be reduced, and it is beneficial to the health of the workers.

[0040] Embodiment 5:

[0041] like Figure 2As shown, in the actual operation of the wind duct, as the length of the wind duct increases, the wind pressure at the far end of the wind duct is greatly reduced, and as the number of air outlets through the wind duct increases, the wind pressure and air volume supplied to the device are further reduced. Therefore, in order to improve the stability of the air outlet of the device, a connecting pipe 20 is installed between the air inlet pipe 3 and the shell 2, and a boosting device 21 is installed on the connecting pipe 20. The boosting device 21 is also connected to the control end 24. When in use, when the air supply speed in the air inlet pipe 3 is difficult to meet the strength requirements of the air curtain wall, at this time, the first control valve 8 is closed, and the control end 24 controls the boosting device 21 to start, and the boosting device 21 forcibly extracts the air in the wind duct and inputs air into the shell 2, thereby increasing the air pressure in the shell 2 and increasing the wind speed and air volume in the air outlet pipe 4 to meet the strength requirements of the air curtain wall.

[0042] By providing the connecting pipe 20 and installing the boosting device 21, when the gas supply to the device is insufficient, the gas supply pressure of the device can be increased to meet the use requirements of the device.

[0043] Embodiment 6:

[0044] like Figure 6 As shown, in practice, considering that the devices need to be used in series or in parallel, an exhaust pipe 22 is installed on one side of the shell 2. The exhaust pipe 22 can be connected to the air inlet pipe 3 of another device to supply air to another device. Of course, the air supply needs of the previous device must be guaranteed before the next device is supplied. Therefore, a second electric control valve 23 is installed on the exhaust pipe 22. When the air supply strength of the previous device is insufficient, the second electric control valve 23 is controlled to close through the control end 24, so that the air duct of the exhaust pipe 22 is blocked. On the contrary, the second electric control valve 23 can be automatically opened through the control end 24, and the air in the shell 2 can be supplied to the next device through the exhaust pipe 22. When multiple devices are connected to the ventilator in sequence, it is not necessary to set the exhaust pipe 22 and the second electric control valve 23, or the second electric control valve 23 can be kept in a normally closed state. It is worth noting that the exhaust pipe 22 can also be used to supply air to other gas-using equipment.

[0045] By installing the exhaust pipe 22 and the second electric control valve 23 on one side of the shell 2, it is convenient to connect with other devices for air supply.

[0046] Working principle: When in use, the air in the air duct enters the shell 2 through the air inlet pipe 3, and then enters the air curtain generator 6 from the shell 2. The air curtain generator 6 compresses the air and then expands the air to make the air ejected at a higher speed. Then the air control pipe 7 located at the end of the air outlet pipe 4 diverts the high-speed airflow in the air outlet pipe 4, so that the airflow forms an air curtain wall (air curtain wall) in front of the air outlet pipe 4, blocking the dust in the tunnel from continuing to move forward, thereby achieving a dust control effect. In front of the air curtain wall, the spray dust reduction device sprays water mist to reduce dust and reduce the dust content in the tunnel.

[0047] At the same time, the dust concentration sensor 10 is located behind the air outlet 4, and can detect the dust concentration behind the air curtain wall and transmit the result to the control end 24. When the dust concentration at the rear decreases, the dust concentration sensor 10 transmits the result to the control end 24. The control end 24 controls the first electric control valve 8 to start, reduce the air intake of the device, reduce the air output of the air outlet 4, and then reduce the strength of the generated air curtain wall. On the contrary, increase the air intake and increase the strength of the air curtain wall. During this period, the air volume sensor 9 monitors the air volume and wind speed data near the outlet side of the air outlet 4 in real time, and transmits the data to the control end 24. The control end 24 displays the data in real time on the display screen of the input component 5. Through the above steps, the device can intelligently control the air output of the device according to the real-time dust concentration changes in the lane, form a stable and controllable air curtain wall, intercept dust more efficiently, prevent dust diffusion, and improve dust control efficiency.
