Description

Technical Field

[0001] The invention relates to the technical field of dust reduction, and in particular to a dust reduction device for green demolition and reconstruction of bridges. Background Art

[0002] The dust pollution caused by bridge demolition has potential impacts on the surrounding environment and residents' health; therefore, in order to protect the environment and people's health, dust reduction treatment is required for the demolition project.

[0003] The existing dust suppression devices for bridge demolition and reconstruction mostly use manually held water pipes with nozzles or water trucks to suppress the dust caused by bridge demolition. Although the dust suppression method can be achieved through the principle of collision, adsorption and condensation of sprayed water mist particles with dust particles, the water pipe needs to be held manually, which increases the manual load and is inconvenient to adjust the spraying height and width of the spray. In addition, spray dust removal only suppresses dust and cannot remove dust. After the water mist dries, the dust will be raised again. Summary of the invention

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the present invention is that water mist dust reduction increases the labor load, and it is inconvenient to adjust the spraying height and width of the spray, and the dust will be re-blown after drying.

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is: a dust reduction device for green demolition and reconstruction of bridges, comprising a water tank and a nozzle, the bottom end of the water tank is evenly connected with universal wheels, the top end of the water tank is connected with a shell, a fan is connected inside the shell, a plurality of wind collecting hoods are circumferentially connected to the shell, a partition is connected above the shell and the fan, a dust filter assembly and a cleaning assembly for cleaning the dust filter assembly are connected on the partition, a pump is connected to the top end of the shell, a feed pipe is connected to the input end of the pump, and the The feed pipe seal passes through the shell, the dust filter assembly and the partition and extends to the bottom of the water tank at the other end. The output end of the pump is connected with a telescopic tube. The shell is evenly connected with telescopic cylinders around the pump. The power end of the telescopic cylinder is connected with a fixed disk. A cavity is connected inside the fixed disk. The other end of the telescopic tube is connected to the cavity. The fixed disk is evenly connected with a movable tube with one end open in a sliding and sealing manner around the cavity. The nozzles are evenly connected to the free end of the movable tube. The fixed disk is connected with a driving assembly that can drive the movable tube to slide.

[0008] Furthermore, the dust filter assembly includes a plurality of through holes evenly connected to the partition, a lifting plate is slidably connected to the top of the outer shell, a filter bag is connected between the bottom end of the lifting plate and the through holes, the dust-laden air is introduced into the filter bag through the through holes, and then the dust in the air is filtered by the filter bag and introduced into the external space of the filter bag between the partition and the lifting plate. As the air accumulates, the air pressure increases, causing the lifting plate to slide.

[0009] Furthermore, the circumferential inner wall of the shell is evenly connected with slide grooves, and the lifting plate is relatively connected with sliders in the circumferential direction. The sliders are slidably matched with the slide grooves, so that the lifting plate can slide up and down along the slide groove direction through the sliding match between the sliders and the slide grooves.

[0010] Furthermore, the cleaning assembly includes a spring connected between the slider and the slide groove, and the top of the shell is connected with a plurality of through holes, and the through holes are located within the length range of the slide groove. When the lifting plate slides up along the slide groove, the spring is compressed and stores force until the lifting plate is located above the through hole. At this time, the clean air in the external space of the filter bag between the partition and the lifting plate is discharged through the through hole, so that the internal air pressure is reduced. Under the resetting action of the spring, the lifting plate moves down along the slide groove, so that the filter bag is vibrated intermittently, which facilitates the vibration of the dust filtered and accumulated in the filter bag to the bottom wall of the shell.

[0011] Furthermore, the other end of the feed pipe passes through the outer shell, the lifting plate, the partition and the water tank in sequence from top to bottom, and a gap is provided between the free end of the feed pipe and the bottom wall of the water tank.

[0012] Furthermore, a conical guide plate is connected to the bottom of the shell, a dust collecting bin is connected to the shell in the circumferential direction of the guide plate, and a baffle is hinged in the circumferential direction of the dust collecting bin. Dust is introduced into the dust collecting bin through the guide plate for collection.

[0013] Furthermore, the driving assembly includes a connecting plate connected to the fixed plate, the connecting plate is connected with a motor, the power output end of the motor is connected with a gear, the fixed plate is rotatably connected with a turntable, the turntable is circumferentially connected with a gear ring, the gear ring is meshed with the gear, the turntable is evenly arrayed with drive grooves, the movable tube is connected with a drive column, the drive column and the drive groove are slidably matched, by starting the motor, the motor drives the gear, the gear drives the turntable to rotate by meshing with the gear ring, the turntable drives the movable tube through the sliding match between the drive groove and the drive column to drive the nozzle to slide and retract, so as to facilitate the adjustment of the spraying width of the nozzle.

[0014] Furthermore, the driving groove is an arc-shaped structure or is arranged obliquely, so as to facilitate the sliding of the movable tube in coordination with the rotation of the turntable and avoid interference with the sliding of the movable tube.

[0036] Embodiment 2

[0037] Based on the first embodiment, combined with the attached Figure 5 and Figure 7 , a fan 4 is connected to the shell 3, a plurality of air collecting covers 5 are circumferentially connected to the shell 3, a partition 6 is connected to the shell 3 above the fan 4, a dust filter assembly and a cleaning assembly for cleaning the dust filter assembly are connected to the partition 6, the dust filter assembly includes a plurality of through holes 14 evenly connected to the partition 6, a lifting plate 15 is slidably connected to the top of the shell 3, a slide groove 17 is evenly connected to the inner wall of the shell 3, a slider 18 is circumferentially connected to the lifting plate 15, the slider 18 slides with the slide groove 17, and a filter bag 16 is connected between the bottom end of the lifting plate 15 and the through hole 14; the cleaning assembly includes a spring 19 connected between the slider 18 and the slide groove 17, a plurality of through holes 20 are connected to the top of the shell 3, the through holes 20 are located within the length range of the slide groove 17, a conical guide plate 22 is connected to the bottom end of the shell 3, and a dust collecting bin 23 is circumferentially connected to the guide plate 22 of the shell 3.

[0038] By starting the fan 4, the fan 4 drives the dust-containing air to be introduced into the housing 3 through the dust collecting hood 5, and then the dust-containing air is filtered through the filter bag 16, and the clean air is introduced into the external space of the filter bag 16 between the partition 6 and the lifting plate 15.

[0039] The specific usage is as follows:

[0040] By starting the pump 7, the pump 7 guides the water in the water tank 1 into the cavity 12 through the delivery pipe 8, and then guides the water out through the nozzle 2 on the movable pipe 13;

[0041] The telescopic cylinder 10 is provided to facilitate supporting the fixed plate 11, and can also drive the fixed plate 11 and the movable tube 13 to adjust the height, so as to facilitate adjusting the spraying height according to the needs;

[0042] The movable tube 13 can be driven to slide through the circumference of the fixed disk 11 through the driving assembly. By starting the motor 24, the motor 24 drives the gear 25. The gear 25 drives the turntable 26 to rotate by meshing with the ring gear 27.

The driving groove 28 is an arc-shaped structure or an inclined setting, which is convenient for cooperating with the rotation of the turntable 26 to drive the movable tube 13 to slide, thereby avoiding interference with the sliding of the movable tube 13.

[0043] The coordinated arrangement of the housing 3, the fan 4, the air collecting cover 5, the partition 6 and the dust filter assembly facilitates starting the fan 4, and the fan 4 introduces the external dust-containing air into the housing 3 through the air collecting cover 5, and the dust-containing air is introduced into the filter bag 16 through the through hole 14, and then the dust in the air is filtered by the filter bag 16 and then introduced into the external space of the filter bag 16 between the partition 6 and the lifting plate 15; the dust filtered on the dust filter assembly can be cleaned by the cleaning assembly, and as the air in the external space of the filter bag 16 between the partition 6 and the lifting plate 15 accumulates, the air pressure increases, causing the lifting plate 15 to move along the slide groove 17 When sliding up, the spring 19 is compressed and accumulates force until the lifting plate 15 is located above the through hole 20. At this time, the clean air in the external space of the filter bag 16 between the partition 6 and the lifting plate 15 is discharged through the through hole 20, so that the internal air pressure is reduced. Under the reset action of the spring 19, the lifting plate 15 moves down along the slide groove 17, and so on, so that the filter bag 16 is intermittently vibrated, which facilitates the vibration of the dust filtered and accumulated in the filter bag 16 to the bottom wall of the shell 3, and then introduced into the dust collecting bin 23 for collection through the guide plate 22, so as to avoid the accumulation of dust on the filter bag 16 and affect the subsequent dust filtering efficiency.
