Description

Excessive concentration of dust floating in the construction environment has a certain impact on the visibility of the construction site and the health of construction workers. Small solid particles such as dust have a strong adsorption capacity. They can enter the human lungs with people's breathing, and stay in different parts of the respiratory tract by collision, diffusion, deposition, etc., causing respiratory diseases.

[0003] In the existing tunnel construction environment, ventilation equipment such as ventilators are generally used to treat the smoke and dust generated in the tunnel construction environment.

At the same time, the dust particles remaining in the dust removal equipment are easily caused by external impact and other factors, which requires secondary cleaning of the dust, resulting in an increase in the working cost of the dust removal equipment.

[0037] like Figures 1 to 10 As shown, the embodiment of the present invention provides an electrostatic dust removal system and control method for reducing secondary dust in a tunnel construction environment, an electrostatic dust removal system for reducing secondary dust in a tunnel construction environment, characterized in that: it comprises a mounting bracket 1, a control module 2 is fixedly mounted on the top of the mounting bracket 1, an air intake pipe 3 is mounted on one side of the inner wall of the top of the mounting bracket 1, an air suction device 4 is mounted on the inner wall of the air intake pipe 3, a dust removal box 5 is connected through one end of the air intake pipe 3, a water tank 6 is fixedly mounted on the bottom end of the dust removal box 5, a filter plate 7 is nested on the top of the inner wall of the water tank 6, a sliding bar 8 is mounted on the inner wall of the dust removal box 5, and the number of the sliding bars 8 is set to two groups, and the two groups of sliding bars 8 are provided. 8 is fixedly installed on the inner wall of the dust removal box 5 along the same axis; an adjusting component 9 is installed at one end of the inner wall of the dust removal box 5, and the adjusting component 9 is used to adjust the spacing of the dust removal component 10; the dust removal component 10, the outer surface of the sliding rod 8 is provided with a dust removal component 10, and the dust removal component 10 is used to remove dust from the air sucked into the dust removal box 5; a cleaning component 11, a cleaning component 11 is installed at the bottom end of the dust removal component 10, and the cleaning component 11 is used to perform secondary cleaning and dust removal on the dust removal component 10; an extrusion component 12, an extrusion component 12 is installed on one side of the cleaning component 11, and the extrusion component 12 is used to extrude the cleaning component 11.

[0038] By setting the adjustment component 9 and adjusting the distance between the two sets of mounting frames 101, the dust removal component 10 can adjust the dust adsorption distance. By setting the dust removal component 10, the characteristics of polyurethane having stronger polarity and higher surface energy are utilized to ensure the adsorption effect of the dust absorption plate 104 on the dust particles in the smoke. By setting the cleaning component 11, the dust particles on the surface of the dust absorption plate 104 are transferred while avoiding the dust particles in the smoke from causing secondary pollution in the dust removal box 5. By setting the extrusion component 12, the filter plate 7 and the water tank 6 are cooperated to filter and collect the squeezed sewage, and the water in the liquid storage barrel 113 is circulated and replenished, so as to ensure the cleaning effect of the cleaning component 11 while reducing the use cost.

[0039] like Figure 3 As shown, the adjustment component 9 includes a turntable 91, which is nested and installed on one end of the surface of the dust removal box 5, and a gear plate 92 is installed at one end of the turntable 91. A bevel gear 93 is meshed and installed on one side of the gear plate 92. The bevel gear 93 is installed on one side of the inner wall of the dust removal box 5. The number of bevel gears 93 is set to two groups, and the two groups of bevel gears 93 are installed on one side of the inner wall of the dust removal box 5 on the same axis. One end of the bevel gear 93 is connected to a screw 94, and the other end of the screw 94 is installed on the inner wall of the dust removal box 5.

[0040] The operator first rotates the turntable 91, and the turntable 91 drives the gear plate 92 to rotate synchronously. The gear plate 92 rotates and engages the two sets of helical gears 93 to rotate. The two sets of helical gears 93 rotate and drive the screw rod 94 to rotate on the inner wall of the dust removal box 5. The screw rod 94 rotates and the two sets of mounting frames 101 threadedly sleeved on the surface of the screw rod 94 slide along the direction of the slide rod 8.

[0041] When the two sets of mounting frames 101 slide, they move away from or approach each other. When the mounting frames 101 slide, they drive the two sets of rotating rods 102 and the two sets of pulley groups 103 mounted on the outer surfaces of the two sets of rotating rods 102 to move away from or approach each other, so that the distance between the dust collecting plates 104 equidistantly installed on the surface of the pulley group 103 changes, thereby achieving an adjustment effect on the dust collecting plates 104.

[0042] By setting the coordination between the meshing plate 92, the bevel gear 93 and the screw 94, the adjustment effect of the distance between the two groups of mounting frames 101 is achieved. By adjusting the distance between the two groups of mounting frames 101, the dust adsorption distance of the dust removal component 10 is adjusted. In actual use, the adsorption effect of the dust removal component 10 on dust particles in the smoke is improved by changing the adsorption distance of the dust removal component 10 according to the smoke concentration generated during construction, thereby improving the applicability of the dust removal component 10 for adsorbing and removing dust in different smoke conditions.

[0043] like Figures 4 to 5As shown, the dust removal assembly 10 includes a mounting frame 101, one end of the mounting frame 101 is sleeved on the surface of the slide rod 8, and the other end of the mounting frame 101 is threadedly sleeved on the surface of the screw rod 94. The number of mounting frames 101 is set to two groups, and two groups of rotating rods 102 are installed on the inner wall of the mounting frame 101. The outer surfaces of the two groups of rotating rods 102 are sleeved with pulley groups 103. The number of pulley groups 103 is set to two groups, and dust collection plates 104 are equidistantly installed on the surfaces of the two groups of pulley groups 103. The surface is coated with polyurethane material, a rubber plate 105 is installed on the top of the mounting frame 101, the dust collecting plate 104 is in contact with the rubber plate 105, a bevel gear set 106 is installed at one end of one of the rotating rods 102 in the two groups of mounting frames 101, one end of the bevel gear set 106 in the two groups of mounting frames 101 is connected by a telescopic rod 107, a motor 108 is installed at one end of the mounting frame 101, and one end of the motor 108 is connected to one end of one of the rotating rods 102 in one of the groups of mounting frames 101.

[0044] Subsequently, the control module 2 controls the air suction device 4 to start, and the air suction device 4 sucks the smoke generated by the tunnel construction through the air intake pipe 3, and the smoke enters the dust removal box 5 through the air intake pipe 3. At the same time, the control module 2 controls the motor 108 to start, and the motor 108 drives one group of rotating rods 102 to rotate synchronously. While the rotating rods 102 rotate, the other group of rotating rods 102 is driven to rotate synchronously through the pulley group 103. While the rotating rods 102 rotate, the input end of the bevel gear group 106 is driven to rotate synchronously. The input end of the bevel gear group 106 rotates and meshes with the bevel gear group 106. The output end of bevel gear set 106 rotates synchronously, and the output end of bevel gear set 106 rotates while driving the input end of another bevel gear set 106 to rotate synchronously through telescopic rod 107, and the input end of another bevel gear set 106 rotates while meshing with the output end of another bevel gear set 106 to rotate synchronously, and the output end of another bevel gear set 106 rotates while driving one of the rotating rods 102 in another mounting frame 101 to rotate synchronously, and this rotating rod 102 rotates while driving the other rotating rod 102 to rotate synchronously through pulley set 103;

[0045] As the pulley set 103 rotates, it drives multiple groups of dust collecting plates 104 arranged equidistantly on the surface to pass through and contact the rubber plate 105 in sequence. Since polyurethane has stronger polarity and higher surface energy, when the polyurethane material on the surface of the dust collecting plate 104 contacts and rubs the rubber plate 105, strong static electricity will be generated on the surface of the dust collecting plate 104. Subsequently, when the multiple groups of dust collecting plates 104 are charged and rotated in sequence, the static electricity generated on the surface of the multiple groups of dust collecting plates 104 absorbs the smoke entering the dust removal box 5, and absorbs the dust particles carried in the smoke to the surface of the dust collecting plate 104, thereby removing the smoke generated during construction.

[0046] By setting friction cooperation between multiple groups of dust collecting plates 104 and rubber plates 105, and utilizing the characteristics of polyurethane with stronger polarity and higher surface energy, multiple groups of dust collecting plates 104 are made to rub against the rubber plates 105 in turn and generate static electricity. Through the cyclic rotation effect of multiple groups of dust collecting plates 104, the smoke entering the dust removal box 5 is circulated and dust removed, avoiding the accumulation of dust particles on the surface of a single number of dust collecting plates 104 after adsorbing the smoke, resulting in a decrease in the adsorption effect, thereby ensuring the adsorption effect of the dust collecting plates 104 on the dust particles in the smoke.

[0047] like Figure 6 to Figure 7 As shown, the cleaning assembly 11 also includes a liquid storage barrel 113, a piston disc 114 is fitted in the internal cavity of the liquid storage barrel 113, a push rod 115 is installed at one end of the piston disc 114, a reciprocating screw rod 1150 is sleeved at one end of the push rod 115, the reciprocating screw rod 1150 is installed on one side of the mounting frame 101, and one end of the reciprocating screw rod 1150 is sleeved with one of the pulleys in the pulley group 3 116, and the pulley group 3 11 Another set of pulleys in 6 is sleeved on one end of a sponge roller 111, a one-way valve 117 is installed at one end of a liquid storage barrel 113, and a dropper 118 is connected to one end of the one-way valve 117 through a hose. The dropper 118 is installed at the bottom end of one side of the mounting frame 101, and the dropper 118 is arranged at an angle of 70 degrees to the sponge roller 111. A one-way valve 119 is installed at one end of the liquid storage barrel 113, and one end of the one-way valve 119 is connected to the bottom end of the water tank 6 through a hose.

[0048] The rotating rod 102 on the bottom of the inner wall of the mounting frame 101 rotates, and at the same time, one of the pulleys in the pulley group 2 112 rotates. When one of the pulleys rotates, another pulley is driven to rotate through a belt. When the other pulley rotates, the sponge roller 111 is driven to rotate synchronously. When the sponge roller 111 rotates, one of the pulleys in the pulley group 3 116 is driven to rotate synchronously. When one of the pulleys rotates, another pulley in the pulley group 3 116 is driven to rotate through a belt. When the other pulley rotates, the reciprocating screw rod 1150 is driven to rotate synchronously. When the reciprocating screw rod 1150 rotates, the push rod 115 sleeved on the outer surface of the reciprocating screw rod 1150 slides in the direction of the reciprocating screw rod 1150. When the push rod 115 slides, it drives the piston disc 114 to slide and squeeze in the liquid storage barrel 113, so that the liquid storage barrel 1150 is filled with liquid. The water stored in the water tank 3 is squeezed to the one-way valve 117, and enters the dropper 118 through the hose at one end of the one-way valve 117. Under the continuous squeezing action of the piston disc 114, the water entering the dropper 118 drips onto the surface of the sponge roller 111 through the dropper 118, so that the surface of the sponge roller 111 absorbs the water. Similarly, when the reciprocating screw rod 1150 continues to rotate, the push rod 115 sleeved on the outer surface of the reciprocating screw rod 1150 slides in the opposite direction of the reciprocating screw rod 1150. While the push rod 115 slides in the opposite direction, it drives the piston disc 114 to slide and suck in the liquid storage barrel 113. Under the suction action of the piston disc 114, the water at the bottom of the water tank 6 is sucked to the one-way valve 119 through the hose, and under the continuous suction action of the piston disc 114, it enters the liquid storage barrel 113 through the one-way valve 119, completing the refilling of the water in the liquid storage barrel 113.

[0049] The pulley set 103 continues to rotate to drive the dust collecting plate 104. The dust collecting plate 104 follows the rotation of the pulley set 103 and approaches and contacts the sponge roller 111. The sponge roller 111 rotates and contacts the surface of the pulley set 103. Since water has good conductivity, after the sponge roller 111 with water on the surface contacts the dust collecting plate 104, the static electricity on the surface of the dust collecting plate 104 will be conducted away by the water on the surface of the sponge roller 111, so that the static electricity on the surface of the dust collecting plate 104 disappears. At this time, when the sponge roller 111 with water on the surface rotates and contacts the surface of the dust collecting plate 104, the dust particles on the surface of the dust collecting plate 104 are rotated and cleaned.

[0050] By setting up the cooperation among the liquid storage barrel 113, the dropper 118 and the sponge roller 111, the surface of the sponge roller 111 is supplemented with water through the dropper 118, and the good conductivity of water is utilized. When the sponge roller 111 contacts the surface of the dust collecting plate 104, the static electricity on the surface of the dust collecting plate 104 is secondary conducted, so that the dust particles on the surface of the dust collecting plate 104 that are statically adsorbed fall off, and at the same time, with the rotation effect of the sponge roller 111, the dust particles on the surface of the dust collecting plate 104 are cleaned, and the statically charged water on the surface of the sponge roller 111 transfers the dust particles on the surface of the dust collecting plate 104. 1 is in a wet state, so that the dust particles are kept wet at the same time, thereby avoiding the secondary dusting of the dust particles during the transfer, and ensuring the dust absorption effect of the dust absorption plate 104 on the smoke and dust removal while avoiding the dust particles in the smoke from causing secondary pollution in the dust removal box 5. At the same time, by utilizing the cooperation between the reciprocating screw rod 1150 and the piston disc 114, through the reciprocating sliding of the piston disc 114 in the liquid storage barrel 113, and cooperating with the one-way effect of the one-way valve 117 and the one-way valve 2 119, the circulation replenishment of the water in the liquid storage barrel 113 is realized, and the operation continuity among the liquid storage barrel 113, the dropper 118 and the sponge roller 111 is ensured.

The extrusion assembly 12 also includes a sponge roller 126, which is installed on one side of the inner wall of the installation frame 101, and one side surface of the sponge roller 126 is in contact with the surface of the dust collecting plate 104. A guide groove 127 is installed on the inner wall of the installation frame 101, and an extrusion plate 128 is installed on the bottom end of the inner wall of the guide groove 127, and the extrusion plate 128 is in press contact with the bottom surface of the sponge roller 126.

[0052] When the sponge roller 111 rotates, the input end of the bevel gear set 121 is driven to rotate synchronously. When the input end of the bevel gear set 121 rotates, the output end of the bevel gear set 121 is meshed with the input end of the bevel gear set 121 to rotate synchronously. When the output end of the bevel gear set 121 rotates, the input end of the bevel gear set 123 is driven to rotate synchronously through the telescopic rod 122. When the input end of the bevel gear set 123 rotates, the output end of the bevel gear set 123 is meshed with the output end of the bevel gear set 123 to rotate synchronously. When the output end of the bevel gear set 123 rotates, the reciprocating screw rod 124 is driven to rotate. Under the rotation of the reciprocating screw rod 124, the extrusion plate 125 sleeved on the outer surface of the reciprocating screw rod 124 reciprocates along the direction of the reciprocating screw rod 124. When the extrusion plate 125 slides, the surface of the sponge roller 126 is squeezed to squeeze out the dust and sewage on the surface of the sponge roller 126. After being squeezed out, the sewage flows into the water tank 6 along the bottom end of the inner wall of the dust removal box 5, and enters the water tank 6 after being filtered by the filter plate 7;

[0053] At the same time, the dust collecting plate 104 continues to rotate with the pulley group 103 after being cleaned by the sponge roller 111. When the dust collecting plate 104 passes through the sponge roller 126, under the action of friction, the dust collecting plate 104 contacts and drives the sponge roller 126. The sponge roller 126 absorbs the residual water on the surface of the dust collecting plate 104 while rotating. When the sponge roller 126 rotates, the squeezing plate 128 squeezes the bottom surface of the sponge roller 126 to squeeze out the water absorbed by the sponge roller 126, and guides the water squeezed out by the sponge roller 126 through the guide groove 127. At the same time, the air after dust removal is discharged through the opening at one end of the dust removal box 5, thereby completing the dust removal of the smoke generated during construction.

[0054] By setting the cooperation between the reciprocating screw rod 124 and the extrusion plate 125, the dust and water mixture on the surface of the sponge roller 111 is squeezed, and the surface of the sponge roller 111 is cleaned twice, so as to further ensure the cleaning effect of the sponge roller 111 on the dust collecting plate 104. At the same time, the squeezed sewage is filtered and collected by the filter plate 7 and the water tank 6, and the water in the liquid storage barrel 113 is circulated and replenished, so as to ensure the cleaning effect of the cleaning component 11 and reduce the use cost. At the same time, the residual water on the surface of the dust collecting plate 104 is adsorbed and collected by the sponge roller 126, so as to ensure the friction effect between the dust collecting plate 104 and the rubber plate 105.

[0055] The present application also provides another technical solution: a method for using an electrostatic dust removal system to reduce secondary dust in a tunnel construction environment, wherein the control method comprises the following steps:

[0056] S1. The operator adjusts the spacing of the dust removal components 10 in real time by adjusting the components 9 according to the actual situation of smoke and dust at the construction site;

[0057] S2, the control module 2 controls the air suction device 4 to start, and the air suction device 4 sucks the smoke into the dust removal box 5 through the air intake pipe 3, and drives the dust removal component 10 to perform electrostatic dust removal on the smoke;

[0058] S3, the dust removal component 10 removes dust while the cleaning component 11 is linked, and the dust adsorbed by the dust removal component 10 is cleaned by the cleaning component 11 to avoid generating dust;

[0059] S4, the squeezing component 12 squeezes and collects the sewage on the surface of the cleaning component 11, and dries the residual water on the surface of the dust removal component 10.

[0060] The working principle of the technical solution provided by the present invention is as follows:

[0061] The operator first rotates the turntable 91, and the rotation of the turntable 91 drives the gear plate 92 to rotate synchronously. The gear plate 92 rotates and engages the two sets of bevel gears 93 to rotate. The two sets of bevel gears 93 rotate and drive the screw 94 to rotate on the inner wall of the dust removal box 5. The rotation of the screw 94 causes the two sets of mounting frames 101 threadedly sleeved on the surface of the screw 94 to slide along the direction of the slide rod 8.

[0062] When the two sets of mounting frames 101 slide, they move away from or approach each other. When the mounting frames 101 slide, they drive the two sets of rotating rods 102 and the two sets of pulley groups 103 mounted on the outer surfaces of the two sets of rotating rods 102 to move away from or approach each other, so that the distance between the dust collecting plates 104 equidistantly installed on the surface of the pulley group 103 changes, thereby achieving an adjustment effect on the dust collecting plates 104.

[0063] Subsequently, the control module 2 controls the air suction device 4 to start, and the air suction device 4 sucks the smoke generated by the tunnel construction through the air intake pipe 3, and the smoke enters the dust removal box 5 through the air intake pipe 3. At the same time, the control module 2 controls the motor 108 to start, and the motor 108 drives one group of rotating rods 102 to rotate synchronously. While the rotating rods 102 rotate, the other group of rotating rods 102 is driven to rotate synchronously through the pulley group 103. While the rotating rods 102 rotate, the input end of the bevel gear group 106 is driven to rotate synchronously. The input end of the bevel gear group 106 rotates and meshes with the bevel gear group 106. The output end of bevel gear set 106 rotates synchronously, and while the output end of bevel gear set 106 rotates, the input end of another bevel gear set 106 is driven to rotate synchronously through telescopic rod 107, and while the input end of another bevel gear set 106 rotates, it engages with the output end of another bevel gear set 106 and rotates synchronously, and while the output end of another bevel gear set 106 rotates, it drives one of the rotating rods 102 in another mounting frame 101 to rotate synchronously, and while this group of rotating rods 102 rotates, it drives another group of rotating rods 102 to rotate synchronously through pulley set 103.

[0064] As the pulley set 103 rotates, it drives multiple groups of dust collecting plates 104 arranged equidistantly on the surface to pass through and contact the rubber plate 105 in sequence. Since polyurethane has stronger polarity and higher surface energy, when the polyurethane material on the surface of the dust collecting plate 104 contacts and rubs the rubber plate 105, strong static electricity will be generated on the surface of the dust collecting plate 104. Subsequently, when the multiple groups of dust collecting plates 104 are charged and rotated in sequence, the static electricity generated on the surface of the multiple groups of dust collecting plates 104 absorbs the smoke entering the dust removal box 5, and absorbs the dust particles carried in the smoke to the surface of the dust collecting plate 104, thereby removing the smoke generated during construction.

[0065] The rotating rod 102 on the bottom of the inner wall of the mounting frame 101 rotates, and at the same time, one of the pulleys in the pulley group 2 112 rotates. When one of the pulleys rotates, another pulley is driven to rotate through a belt. When the other pulley rotates, the sponge roller 111 is driven to rotate synchronously. When the sponge roller 111 rotates, one of the pulleys in the pulley group 3 116 is driven to rotate synchronously. When one of the pulleys rotates, another pulley in the pulley group 3 116 is driven to rotate through a belt. When the other pulley rotates, the reciprocating screw rod 1150 is driven to rotate synchronously. When the reciprocating screw rod 1150 rotates, the push rod 115 sleeved on the outer surface of the reciprocating screw rod 1150 slides in the direction of the reciprocating screw rod 1150. When the push rod 115 slides, it drives the piston disc 114 to slide and squeeze in the liquid storage barrel 113, so that the liquid storage barrel 1150 is filled with liquid. The water stored in the tank 113 is squeezed to the one-way valve 117, and enters the dropper 118 through the hose at one end of the one-way valve 117. Under the continuous squeezing action of the piston disc 114, the water entering the dropper 118 drips onto the surface of the sponge roller 111 through the dropper 118, so that the surface of the sponge roller 111 absorbs the water. Similarly, when the reciprocating screw rod 1150 continues to rotate, the push rod 115 sleeved on the outer surface of the reciprocating screw rod 1150 slides in the opposite direction of the reciprocating screw rod 1150. While the push rod 115 slides in the opposite direction, it drives the piston disc 114 to slide and suck in the liquid storage barrel 113. Under the suction action of the piston disc 114, the water at the bottom of the water tank 6 is sucked to the one-way valve 119 through the hose, and under the continuous suction action of the piston disc 114, it enters the liquid storage barrel 113 through the one-way valve 119, thereby completing the replenishment of the water in the liquid storage barrel 113.

[0066] The pulley set 103 continues to rotate to drive the dust collecting plate 104. The dust collecting plate 104 follows the rotation of the pulley set 103 and approaches and contacts the sponge roller 111. The sponge roller 111 rotates and contacts the surface of the pulley set 103. Since water has good conductivity, after the sponge roller 111 with water on the surface contacts the dust collecting plate 104, the static electricity on the surface of the dust collecting plate 104 will be conducted away by the water on the surface of the sponge roller 111, so that the static electricity on the surface of the dust collecting plate 104 disappears. At this time, when the sponge roller 111 with water on the surface rotates and contacts the surface of the dust collecting plate 104, the dust particles on the surface of the dust collecting plate 104 are rotated and cleaned.

[0067] When the sponge roller 111 rotates, the input end of the bevel gear set 121 is driven to rotate synchronously. When the input end of the bevel gear set 121 rotates, the output end of the bevel gear set 121 is meshed with the output end of the bevel gear set 121 to rotate synchronously. When the output end of the bevel gear set 121 rotates, the input end of the bevel gear set 3 123 is driven to rotate synchronously through the telescopic rod 2 122. When the input end of the bevel gear set 3 123 rotates, the output end of the bevel gear set 3 123 is meshed with the output end of the bevel gear set 3 123 to rotate synchronously. When the output end of the bevel gear set 3 123 rotates, the reciprocating screw rod 2 124 is driven to rotate. Under the rotation action of the reciprocating screw rod 2 124, the extrusion plate 125 sleeved on the outer surface of the reciprocating screw rod 2 124 slides back and forth in the direction of the reciprocating screw rod 2 124. When the extrusion plate 125 slides, the surface of the sponge roller 2 126 is squeezed out, and the dust and sewage on the surface of the sponge roller 2 126 are squeezed out. After being squeezed out, the sewage flows into the water tank 6 along the bottom end of the inner wall of the dust removal box 5, and enters the water tank 6 after being filtered by the filter plate 7.

[0068] At the same time, the dust collecting plate 104 continues to rotate with the pulley group 103 after being cleaned by the sponge roller 111. When the dust collecting plate 104 passes through the sponge roller 126, under the action of friction, the dust collecting plate 104 contacts and drives the sponge roller 126. The sponge roller 126 absorbs the residual water on the surface of the dust collecting plate 104 while rotating. When the sponge roller 126 rotates, the squeezing plate 128 squeezes the bottom surface of the sponge roller 126 to squeeze out the water absorbed by the sponge roller 126, and guides the water squeezed out by the sponge roller 126 through the guide groove 127. At the same time, the air after dust removal is discharged through the opening at one end of the dust removal box 5, thereby completing the dust removal of the smoke generated during construction.
