Description

Technical Field

[0001] The invention belongs to the technical field of tunnel construction equipment, and particularly relates to a tunnel construction dust removal device. Background Art

[0002] Although existing tunnel construction dust removal devices are also designed with an arch-shaped spray dust removal structure, the spray dust removal structure takes up a lot of space when not in use, which is not conducive to the transportation and storage of the entire dust removal device. Moreover, relying solely on the spray structure for dust removal, the dust removal effect it can provide is very limited, resulting in a relatively simple dust removal structure and unsatisfactory dust removal effect.

[0003] At the same time, the dust removal structure of the current tunnel construction dust removal device is often equipped with a filter. When the dust removal device is performing dust removal for a long time, a large amount of dust will gradually adhere to the filter, reducing the filtering effect. The filter needs to be cleaned regularly, and the filter cannot be cleaned automatically, thereby reducing the dust removal efficiency of the entire dust removal device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a tunnel construction dust removal device.

[0005] The technical solution adopted to solve the above technical problems is: a tunnel construction dust removal device, including a mobile box as an installation carrier, a funnel bin installed at one end of the mobile box, and a fan installed inside the funnel bin. A first processing bin, a second processing bin, a third processing bin, a fourth processing bin, a fifth processing bin, a sixth processing bin and a water storage bin are sequentially arranged from one end near the fan to the other end of the mobile box, the fourth processing bin and the fifth processing bin are separated by a square partition, and the second processing bin and the third processing bin are also separated by a square partition;

[0006] A spray dust reduction mechanism is provided on the top of the mobile box, a rotating dust removal mechanism is provided at the middle position inside the mobile box, a second dust removal mechanism is provided on one side of the two groups of square partitions close to the fan, a cleaning mechanism that cooperates with the second dust removal mechanism is provided on the top of the two groups of square partitions close to the fan, a first dust removal mechanism is provided inside the first processing bin, a ground dust removal mechanism is provided at one end of the bottom of the mobile box close to the funnel bin, a water supply mechanism for supplying water to the spray dust reduction mechanism, the second dust removal mechanism and the first dust removal mechanism is provided inside the water storage bin, and a sewage discharge mechanism is provided at the bottom end of one side of the mobile box

[0007] Furthermore, the first dust removal mechanism includes a trapezoidal guide block located in the middle of the bottom of the first processing chamber, a first water pipe is installed at one end of the top of the first processing chamber away from the fan, and second spray nozzles are evenly installed at the bottom of the first water pipe.

[0008] Through the above technical solution, after the water supply mechanism supplies water to the inside of the first water pipe, the clean water inside the first water pipe is sprayed out by the second spray nozzle. At this time, the fan cooperates with the negative pressure blower to allow external dust to enter the first processing chamber. During the process, the trapezoidal guide block will guide the movement direction of the dust to the bottom of the second spray nozzle. The water mist sprayed by the second spray nozzle performs preliminary dust reduction treatment on the dust entering the first processing chamber, and the mist droplets mixed with dust then fall into the water inside the first processing chamber.

[0009] Furthermore, the spray dust reduction mechanism includes two groups of hydraulic rods hingedly connected to the top ends of both sides of the movable box body, a support tube is hingedly connected to the middle position of the top of the movable box body near one end of the fan, and a short arc tube is installed at the top end of the support tube through a connecting seat, the top end of the support tube is connected to the interior of the short arc tube, and the two ends of the short arc tube are symmetrically hinged with a long arc tube, and the two groups of long arc tubes are connected to the interior of the short arc tube through a hose, and the outer sides of the two groups of the long arc tubes are symmetrically installed with connecting seats, and the bottoms of the short arc tube and the long arc tube are evenly installed with a first spray nozzle, and the top end of the outer side of the support tube is sleeved with a movable block, and the two sides of the movable block are symmetrically hinged with connecting rods, the top end of the connecting rod is hinged with the connecting seat on the long arc tube, the bottom end of the outer side of the support tube is installed with a mounting seat, and an electric telescopic rod is installed at the middle position of the top of the mounting seat, the output end of the electric telescopic rod is fixedly connected to the bottom end of the movable block, and the output ends of the two groups of hydraulic rods are respectively hinged to both sides of the mounting seat.

[0010] Through the above technical solution, the two groups of hydraulic rods are controlled to extend, so that the support tube rotates to a vertical state with the hinge shaft connected to the top of the mobile box as the axis. Then, the electric telescopic rod is controlled to extend, pushing the movable block to slide upward on the support tube. The movable block cooperates with the connecting rod to push the two groups of long arc tubes to rotate and open with the hinge shaft connected to the short arc tube as the axis, so that the short arc tube and the two groups of long arc tubes form a semicircular tube body. Then, the water supply mechanism is controlled to supply water to the inside of the support tube, and then the clean water is sprayed downward from the first spray nozzle in the form of mist, forming a mist water curtain to block dust.

[0011] Furthermore, the rotating dust removal mechanism includes connecting bearings, which are provided in two groups, and the two groups of connecting bearings are respectively located at one end of the second processing bin and the fifth processing bin away from each other, and the inner rings of the two groups of connecting bearings are jointly installed with a rotating cylinder, and the rotating cylinder passes through the interior of the second processing bin, the third processing bin, the fourth processing bin and the fifth processing bin. Through holes are evenly opened on the surface of the rotating cylinder, and circular partitions are symmetrically installed inside the rotating cylinder near the positions of the two groups of square partitions. A driving component for driving the rotating cylinder to rotate is provided at the top of one side of the interior of the sixth processing bin.

[0012] Through the above technical solution, after the outside air enters the rotating drum with some dust, the dust passes through the through hole on the surface of the rotating drum located inside the second processing chamber and enters the second processing chamber, and then passes through the filter to enter the third processing chamber, and then enters the rotating drum through the through hole located inside the third processing chamber, and then enters the fourth processing chamber through the through hole, and so on and so forth, and finally enters the sixth processing chamber. During this process, the driving component is controlled to drive the rotating drum to rotate slowly and uniformly, so that part of the surface and inner wall of the rotating drum are continuously immersed in clean water and then leave, so that the dust adheres to the surface and inner wall of the rotating drum and then enters the clean water inside the second processing chamber, the third processing chamber, the fourth processing chamber and the fifth processing chamber, so that further dust removal treatment can be achieved.

[0013] Furthermore, the drive assembly includes an annular rack, which is located at one end of the outer side of the rotating cylinder away from the fan. A servo motor is installed at the top of one side inside the sixth processing chamber, and the output shaft of the servo motor is installed with a driving gear that meshes with the annular rack.

[0014] Through the above technical solution, the servo motor is controlled to drive the driving gear to rotate, and the driving gear drives the rotating drum to rotate stably and uniformly through the transmission with the annular rack, ensuring that all parts of the rotating drum are continuously immersed in clean water and then removed, and this process is repeated.

[0015] Furthermore, the second dust removal mechanism includes square through grooves opened on both sides of the square partitions, and a filter screen is installed inside the square through grooves. The tops of the two groups of square partitions close to one end of the fan are both provided with second water pipes, and flushing nozzles are evenly installed at the bottoms of the second water pipes. The second water pipe is located above the rotating cylinder, and rotating shafts connected to the second water pipes are symmetrically provided at the tops of both sides of the movable box.

[0016] Through the above technical solution, in the process of external air carrying dust entering the third processing chamber from the second processing chamber and entering the fifth processing chamber from the fourth processing chamber, the filter can filter the passing air, thereby improving the device's dust filtering and intercepting effect, and then control the water supply mechanism to supply water to the second water pipe, and the flushing nozzle on the second water pipe sprays water to flush the filter, thereby maintaining the filtering effect of the filter.

[0017] Furthermore, the cleaning mechanism includes fixed blocks located on both sides of one end of the square partition, a mounting column is installed on the top of the fixed block, and the top of the mounting column is fixedly connected to the inner top of the movable box body, and the outer sides of the two groups of mounting columns are jointly sleeved with a movable cross bar, and the outer sides of the mounting columns are sleeved with a reset spring, and the top and bottom ends of the reset spring are fixedly connected to the movable cross bar and the fixed block respectively, and vertical plates are symmetrically installed on both sides of the movable cross bar, and strip brushes that cooperate with the filter screen are evenly installed on the side of the vertical plate away from the movable cross bar, and a roller is installed at the middle position of the movable cross bar, and two groups of mounting rings are installed on the outside of the rotating cylinder near the two groups of movable cross bars, and the outer ring of the mounting ring is evenly provided with six groups of arc-shaped protrusions that cooperate with the rollers, and the top of the vertical plate away from one end of the square partition is provided with a linkage component that drives the second water pipe to rotate back and forth.

[0018] Through the above technical solution, when the rotating drum rotates at a uniform speed, the mounting ring on the outside of the rotating drum drives the arc-shaped protrusion to rotate, and the arc-shaped protrusion cooperates with the roller to lift the movable cross bar and then drop it. During the process, the movable cross bar slides on the mounting column, and the reset spring is stretched and then returns to its original state. The movable cross bar drives the vertical plate and the strip brush to move back and forth up and down, thereby realizing automatic cleaning of the filter screen and ensuring the filtering effect of the filter screen.

[0019] Furthermore, the linkage assembly includes an active rack, which is provided in two groups and symmetrically installed at both ends of the outside of the second water pipe. The top of the two groups of vertical plates away from one end of the square partition is installed with a driven gear that meshes with the active rack.

[0020] Through the above technical solution, during the up and down reciprocating motion of the vertical plate, the active rack cooperates with the driven gear to drive the second water pipe to rotate back and forth with the rotating shaft as the axis, so that the flushing nozzle on the second water pipe can continuously change the angle of the water spray, thereby improving the cleaning effect of the strip brush on the filter.

[0021] Furthermore, the ground dust removal mechanism includes a negative pressure fan located on one side of the sixth processing bin, a strip bin is obliquely installed at one end of the bottom of the mobile box close to the fan, and guide plates with different inclination directions are evenly installed at the air outlet inside the strip bin, and arc plates are symmetrically arranged on both sides of the inside of the strip bin, the input end of the negative pressure fan is connected to the top end of the inside of the sixth processing bin, and the output end of the negative pressure fan is connected to the inside of the strip bin through a ventilation pipe.

[0022] Through the above technical solution, a negative pressure fan is used to continuously extract air from the sixth processing chamber, so that its interior is always in a negative pressure state, forcing the outside air to enter the first processing chamber with dust, and the air extracted by the negative pressure fan is transported to the interior of the chamber through the ventilation pipe, and then the guide plate and the arc plate cooperate to enable the air to be sprayed onto the ground in front of the mobile box, lifting the dust on the ground, and then making it easier for the fan to cooperate with the negative pressure fan to suck the dust into the first processing chamber.

[0023] Furthermore, the water supply mechanism includes a water supply pump located at the top of the inner wall of the water storage tank, a water supply pipe is installed on one side of the mobile box, the input end of the water supply pump is connected to the bottom end inside the water storage tank, the output end of the water supply pump is connected to one end of the water supply pipe, and a water supply valve is installed at the other end of the water supply pipe, and the output end of the water supply valve is connected to the bottom end inside the support tube through a hose, and three groups of first connecting heads for water supply are provided on the top of the water supply pipe.

[0024] Through the above technical solution, the water supply pump is controlled to extract clean water from the water storage tank and transport it to the inside of the water supply pipe. The water supply valve supplies water to the inside of the support pipe, and then the three groups of first connecting heads supply water to the inside of the first water pipe and the second water pipe respectively.

[0025] The beneficial effects of the present invention are as follows: (1) The present invention is designed with a foldable spray dust reduction mechanism. When performing dust removal, the spray dust reduction mechanism is fully unfolded, thereby improving the spray dust removal range and effect of the entire device. When not in use, the spray dust reduction mechanism can be completely folded up, reducing the space occupied by the device and facilitating the transportation and storage of the entire tunnel construction dust removal device; (2) After the first dust removal mechanism and the fan cooperate to blow the outside air and dust into the first treatment chamber for preliminary spray dust reduction, the first treatment chamber, the second treatment chamber, the third treatment chamber, the fourth treatment chamber, the fifth treatment chamber and the sixth treatment chamber are all half-filled with clean water. Then, by rotating the dust removal mechanism and the second dust removal mechanism, the outside air with dust can pass through the second treatment chamber, the third treatment chamber, the fourth treatment chamber and the fifth treatment chamber in sequence. After entering the sixth processing chamber, the dust in the outside air will gradually adhere to the inner and outer sides of the rotating drum, and the rotating drum can clean the dust into the clean water in the chamber when it rotates, thereby further improving the dust removal effect of the entire tunnel construction dust removal device, and the dust removal effect of the device can be further improved by the second dust removal mechanism; (3) The present invention is designed with a cleaning mechanism on the surface of the square partition. While using the rotation of the rotating drum to clean the surface of the filter, it can also drive the second water pipe to rotate back and forth continuously, constantly changing the angle of the flushing nozzle to spray water, and thus can flush different positions on the surface of the filter. In combination with the strip brush that can reciprocate to clean the surface of the filter, the surface of the filter can be automatically flushed and cleaned, while ensuring the filtering effect of the filter, and improving the dust removal efficiency of the entire dust removal device.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] like Figure 1-Figure 4 、 Figure 7-10 、 Figure 15-18 、 Figure 20 and Figure 22As shown, a tunnel construction dust removal device of this embodiment includes a mobile box 1 as a mounting carrier, a funnel bin 18 is installed at one end of the mobile box 1, and a fan 8 is installed inside the funnel bin 18. The first processing bin 10, the second processing bin 11, the third processing bin 12, the fourth processing bin 13, the fifth processing bin 14, the sixth processing bin 15 and the water storage bin 16 are sequentially arranged from one end near the fan 8 to the other end of the mobile box 1. The fourth processing bin 13 and the fifth processing bin 14 are separated by a square partition 17, and the second processing bin 11 and the third processing bin 12 are also separated by a square partition 17. At the middle position of the mobile box 1 A rotating dust removal mechanism 3 is provided, and the rotating dust removal mechanism 3 includes a connecting bearing 301. There are two groups of connecting bearings 301, and the two groups of connecting bearings 301 are respectively located at the ends of the second processing chamber 11 and the fifth processing chamber 14 away from each other. The inner rings of the two groups of connecting bearings 301 are jointly installed with a rotating cylinder 302. The rotating cylinder 302 passes through the interior of the second processing chamber 11, the third processing chamber 12, the fourth processing chamber 13 and the fifth processing chamber 14. Through holes 303 are evenly opened on the surface of the rotating cylinder 302. Round partitions 304 are symmetrically installed at the positions near the two groups of square partitions 17 inside the rotating cylinder 302. The top of one side of the interior of the sixth processing chamber 15 is provided. A driving assembly 305 is provided for driving the rotating cylinder 302 to rotate, and the driving assembly 305 includes an annular rack 3051, and the annular rack 3051 is located on the outer side of the rotating cylinder 302 away from the end of the fan 8. A servo motor 3052 is installed at the top of one side of the interior of the sixth processing chamber 15, and the output shaft of the servo motor 3052 is installed with a driving gear 3053 that meshes with the annular rack 3051; a second dust removal mechanism 4 is provided on one side of the two groups of square partitions 17 close to the fan 8, and the second dust removal mechanism 4 includes square through grooves 404 opened on both sides of the square partitions 17, and a filter screen 405 is installed inside the square through grooves 404. A second water pipe 401 is provided at the top of each partition 17 near the fan 8, and flushing nozzles 403 are evenly installed at the bottom of the second water pipe 401. The second water pipe 401 is located above the rotating cylinder 302. Rotating shafts 402 connected to the second water pipe 401 are symmetrically provided at the tops of both sides of the movable box 1. A first dust removal mechanism 6 is provided inside the first processing chamber 10. The first dust removal mechanism 6 includes a trapezoidal guide block 603 located in the middle of the bottom of the first processing chamber 10. A first water pipe 601 is installed at the end of the top of the first processing chamber 10 away from the fan 8, and second spray nozzles 602 are evenly installed at the bottom of the first water pipe 601.After the external dust is sucked into the first processing chamber 10, the trapezoidal guide block 603 will guide the movement direction of the dust to the bottom of the second spray nozzle 602, and control the water supply mechanism 9 to supply water to the inside of the first water pipe 601. The clean water inside the first water pipe 601 is then sprayed out by the second spray nozzle 602 to spray dust reduction on the air passing under the second spray nozzle 602. The mist droplets mixed with dust then fall into the water inside the first processing chamber 10. Then, the air carries some dust into the rotating cylinder 302, and then passes through the through hole 303 located inside the second processing chamber 11 on the surface of the rotating cylinder 302 and enters the second processing chamber 11, and then passes through the filter 405 into the third processing chamber 12, and then enters the rotating cylinder 302 through the through hole 303 located inside the third processing chamber 12, and then enters the fourth processing chamber 13 through the through hole 303, and so on. After entering the sixth processing chamber 15, during this process, the filter 405 can filter the passing air, improving the device's dust filtering and interception effect. The water supply mechanism 9 is then controlled to supply water to the second water pipe 401, and the flushing nozzle 403 on the second water pipe 401 sprays water to flush the filter 405, maintaining the filtering effect of the filter 405. At the same time, the servo motor 3052 is controlled to drive the drive gear 3053 to rotate, and the drive gear 3053 drives the rotating drum 302 to rotate at a stable and uniform speed through the transmission with the annular rack 3051, so that part of the surface and inner wall of the rotating drum 302 is continuously immersed in the clean water and then removed. The dust adheres to the surface and inner wall of the rotating drum 302 and then enters the clean water inside the second processing chamber 11, the third processing chamber 12, the fourth processing chamber 13 and the fifth processing chamber 14, thereby achieving further dust removal.

[0051] like Figures 15-19 and Figure 22As shown, the top of the two groups of square partitions 17 close to the fan 8 of this embodiment is provided with a cleaning mechanism 5 that cooperates with the second dust removal mechanism 4.

The linkage assembly 510 for the reciprocating rotation of the pipe 401 includes an active rack 511. The active rack 511 is provided with two groups, and the two groups of active racks 511 are symmetrically installed at both ends of the outer side of the second water pipe 401. The top of the two groups of vertical plates 505 away from the square partition 17 is installed with a driven gear 512 that meshes with the active rack 511. When the rotating cylinder 302 rotates at a constant speed, the mounting ring 508 on the outer side of the rotating cylinder 302 drives the arc-shaped protrusion 509 to rotate, and the arc-shaped protrusion 509 cooperates with the roller 507 to lift the movable cross bar 503 and then fall down. The middle movable cross bar 503 slides on the mounting column 501, and the reset tension spring 504 is stretched and then returns to its original shape. The movable cross bar 503 drives the vertical plate 505 and the strip brush 506 to move back and forth up and down, thereby realizing automatic cleaning of the filter screen 405. In the process of the vertical plate 505 moving back and forth up and down, the active rack 511 cooperates with the driven gear 512 to drive the second water pipe 401 to rotate back and forth around the rotating shaft 402 as the axis, so that the flushing nozzle 403 on the second water pipe 401 can continuously change the angle of the water spray, thereby improving the cleaning effect of the strip brush 506 on the filter screen 405.

[0052] like Figures 1-6 and Figure 11-14As shown, in this embodiment, a spray dust suppression mechanism 2 is provided on the top of the mobile box 1. The spray dust suppression mechanism 2 includes two groups of hydraulic rods 210 hinged on the top of both sides of the mobile box 1. A support pipe 201 is hinged at the middle position of the top of the mobile box 1 near the end of the fan 8, and a short arc tube 202 is installed on the top of the support pipe 201 through a connecting seat 205. The top of the support pipe 201 is connected to the inside of the short arc tube 202, and the two ends of the short arc tube 202 are symmetrically hinged with long arc tubes 203. The two groups of long arc tubes 203 are connected to the short arc tube through a hose. The interior of 202 is connected, and the outer sides of the two groups of long arc tubes 203 are symmetrically installed with connecting seats 205.

The top of the connecting rod 207 is hinged to the connecting seat 205 on the long arc tube 203. The bottom end of the outer side of the support tube 201 is installed with a mounting seat 208, and the middle position of the top of the mounting seat 208 is installed with an electric telescopic rod 2 09, the output end of the electric telescopic rod 209 is fixedly connected to the bottom end of the movable block 206, and the output ends of the two sets of hydraulic rods 210 are respectively hinged to the two sides of the mounting seat 208. The two sets of hydraulic rods 210 are controlled to extend, so that the support tube 201 rotates to a vertical state with the hinge axis connected to the top of the mobile box 1 as the axis. Then the electric telescopic rod 209 is controlled to extend, pushing the movable block 206 to slide upward on the support tube 201. The movable block 206 cooperates with the connecting rod 207 to push the two sets of long arc tubes 203 with the hinge axis connected to the short arc tube 202 as the axis.
