Description

Technical Field

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

[0002] With the rapid economic and social development of my country, the scale and scope of infrastructure construction are expanding rapidly, and the corresponding engineering geological conditions are becoming more complex. The tunnel construction of the project passes through a large area of ​​medium to strong weathered granite strata with loose structure, poor cohesion and almost no self-stabilization ability. The construction difficulty increases sharply. The construction in the tunnel built on this basis will cause huge amount of dust in the tunnel. Therefore, it is necessary to use corresponding tunnel construction dust removal equipment to ensure the normal construction of the tunnel project.

[0003] Although the existing tunnel construction dust removal device is also designed with an arch-type 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; and the dust removal effect that can be provided by relying solely on the spray structure for dust removal is very limited, which also causes the dust removal structure of the dust removal device to be relatively simple and the dust removal effect is not ideal; at the same time, the dust removal structure of the current tunnel construction dust removal device is often also provided with a filter net. When the dust removal device is performing dust removal for a long time, the filter net will gradually be attached by a large amount of dust and the filtering effect will be reduced. The filter net needs to be cleaned regularly, and the filter net cannot be cleaned automatically, thereby reducing the dust removal efficiency of the entire dust removal device.

Circular partitions are symmetrically installed at the positions of the two groups of square partitions inside the rotating cylinder, and a driving component for driving the rotating cylinder to rotate is arranged at the top of one side of the interior of the sixth processing bin.

[0010] Through the above technical scheme, 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 finally enters the sixth processing chamber. In 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 can be achieved.

[0011] Furthermore, the driving 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.

[0013] Furthermore, the second dust removal mechanism includes square through grooves opened on both sides of the square partitions, and a filter net is installed inside the square through grooves. Second water pipes are arranged on the tops of the two groups of square partitions close to one end of the fan, and flushing nozzles are evenly installed on 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 arranged at the tops of both sides of the movable box.

[0016] Through the above technical scheme, 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 net and ensuring the filtering effect of the filter net.

[0017] Furthermore, the linkage assembly includes an active rack, which is provided with two groups and symmetrically installed at both ends of the outer side of the second water pipe. The top ends of the two groups of vertical plates away from the square partition are equipped with driven gears that mesh with the active racks.

[0021] 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 arranged on the top of the water supply pipe.

[0023] The beneficial effects of the present invention are as follows: (1) The present invention designs 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 to reduce the space occupied by the device, thereby 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 outside air and dust into the first processing bin for preliminary spray dust reduction, the first processing bin, the second processing bin, the third processing bin, the fourth processing bin, the fifth processing bin and the sixth processing bin 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 processing bin, the third processing bin, the fourth processing bin and the fifth processing bin 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 net, it can also drive the second water pipe to rotate back and forth continuously, continuously changing the angle of the flushing nozzle to spray water, and thus can flush different positions on the surface of the filter net, and in combination with a strip brush that can reciprocate and brush the surface of the filter net, it can realize automatic flushing and cleaning of the surface of the filter net, while ensuring the filtering effect of the filter net, it can also improve the dust removal efficiency of the entire dust removal device.
