Description

Technical Field

[0001] The present application relates to the technical field of tunnel blasting dust removal, and in particular to a dust removal device for tunnel air energy blasting. Background Art

[0002] During the construction of tunnels, excavation and blasting are required. Air energy blasting is a technical method that uses the energy generated by the explosion of explosives to transfer to the surrounding rocks or concrete, thereby causing crushing and controlling the destruction of rock mass. In order to increase the speed of the project, it is usually necessary to remove dust from the tunnel after blasting.

[0003] At present, the general dust removal method adopts a water mist spray system. The mist spray system sprays water mist in the tunnel to moisten the dust particles and then settle, thereby reducing the dust concentration in the air.

[0004] However, in actual application, the water mist spray system can easily lead to excessive humidity in the tunnel, affecting the construction progress and the normal use of equipment. Summary of the invention

[0005] In order to improve the effect of tunnel dust removal, the present application provides a dust removal device for tunnel air energy blasting.

[0006] The present application provides a dust removal device for tunnel air energy blasting, which adopts the following technical solution: A dust removal device for tunnel air energy blasting, comprising: Vehicle body; A dust collection assembly including an air duct, a guide plate and a collection box; The air duct is arranged on the vehicle body, and an air pump is arranged on the air duct; There are multiple guide plates, which are arranged around the axis of the air guide tube and connected end to end to form a flared shape, and one end of the guide plate is hinged to the end of the air guide tube; The collection box is fixed on the vehicle body and communicated with the air duct; The adjustment component includes a dust concentration sensor and an adjustment part, wherein the dust concentration sensor is fixedly mounted on the vehicle body and is used to output a dust concentration signal in the tunnel; the adjustment part is provided with multiple groups, and one group of the adjustment parts is provided between each two adjacent guide plates, and the adjustment part is used to adjust the expansion size of the guide plate according to the dust concentration in the tunnel; The cleaning component includes a driving part, a dust collecting part and a cleaning part. The driving part and the cleaning part are both arranged on the collecting box. The dust collecting part is arranged on the driving part. The driving part is used to drive the dust collecting part to move up and down, and drive the dust collecting part to rotate to collect dust; the cleaning part is used to clean the dust on the dust collecting part.

[0007] By adopting the above technical solution, the dust concentration sensor monitors the dust concentration in the tunnel in real time and outputs the dust concentration signal in the tunnel. The adjustment unit adjusts the expansion size of the guide plate according to the dust concentration in the tunnel, which can further increase the dust collection area and improve the dust collection efficiency. Then, the dust in the tunnel is sucked into the air duct through the suction force generated by the air pump, and then sent to the collection box through the air duct, ensuring that the dust and harmful gases are effectively controlled at the source, avoiding the diffusion and accumulation of dust and harmful gases in the tunnel; The driving unit drives the dust collecting unit to move up and down, and performs rotational dust collection on the dust collecting box to ensure efficient dust collection. The cleaning unit cleans the dust on the dust collecting unit to ensure continuous and efficient dust removal operation capability, thereby improving the dust removal effect of the tunnel.

[0008] Optionally, the adjustment unit includes: The folding tube has two ends respectively fixedly connected to two adjacent guide plates; A return spring, both ends of which are respectively fixedly connected to two adjacent guide plates and located in the folding tube; An electric telescopic rod, fixedly mounted on the air duct and electrically connected to the dust concentration sensor via a controller; An air storage box is fixedly mounted on the air guide pipe, and one end of the air storage box is connected to the folding pipe through a connecting pipe; Wherein, a slide plate is slidably connected inside the gas storage box, and the movable end of the electric telescopic rod is penetrated on an end of the gas storage box away from the connecting pipe and is fixedly connected to the slide plate.

[0009] By adopting the above technical solution, the dust concentration sensor monitors the dust concentration in the tunnel in real time and outputs the dust concentration signal in the tunnel. When the dust concentration increases, the controller responds to the dust concentration signal output by the dust concentration sensor and controls the active end of the electric telescopic rod to extend. The active end of the electric telescopic rod drives the slide plate to move, and the slide plate squeezes the air in the air storage box into the folding tube. Since the foldable tube has the foldable characteristic, the air enables the foldable tube to be flexibly unfolded, so that the expansion size of the guide plate is easily adjusted, thereby making it easy to improve the dust collection efficiency and dust removal effect.

[0010] Optionally, the dust collecting unit includes: A fixed ring, rotatably connected to the collection box and located inside the collection box; There are multiple dust collecting plates, which are arranged around the axial direction of the fixed ring. The dust collecting plates are inclined and fixed on the fixed ring, wherein the connection between the collection box and the air duct is located on the rotation path of the dust collecting plates.

[0011] By adopting the above technical solution, the dust-laden airflow falls into the rotating path of the dust collecting plate through the air guide pipe. When the driving unit is started, the fixed ring and the dust collecting plate will rotate around the axial direction, which not only increases the contact area between the dust collecting plate and the dust, but also improves the dust capture efficiency, so that the dust collecting plate can better capture and adsorb the dust during the rotation process, while avoiding the accumulation and sliding of dust on the dust collecting plate.

[0012] Optionally, the dust collecting plate has a mesh structure.

[0013] By adopting the above technical solution, the dust collecting plate with a mesh structure has a larger surface area and can more effectively capture dust particles in the air; due to the presence of the mesh holes, air can pass smoothly, and dust particles will be captured by the edges of the mesh holes, thereby improving the dust collection efficiency.

[0014] Optionally, the cleaning unit includes: A water gun is provided, wherein the water guns are arranged around the vertical axis of the collecting box, the water guns are fixed on the inner wall of the collecting box, and the output end of the water gun is arranged in a direction close to the dust collecting plate; A water tank, fixedly mounted on the vehicle body; Among them, the input ends of the multiple water guns are connected to the water tank through a water pipe, a water pump is arranged on the water pipe, and the water pump is electrically connected to the controller.

[0015] By adopting the above technical solution, the controller controls the water pump to start, and the water pump draws water through the water pipe to the input end of the water gun. The water gun flushes the dust collecting plate with high-pressure water flow. The high-pressure water flow can penetrate the dust layer and effectively remove the dust particles and stains attached to the dust collecting plate, ensuring that all parts of the dust collecting plate can be fully cleaned, avoiding cleaning blind spots, and thus improving cleaning efficiency.

[0016] Optionally, the driving unit includes: A motor, fixedly mounted on the collection box; A screw rod is coaxially connected to the output shaft of the motor; A threaded sleeve, sleeved on the screw and threadably connected to the screw; A limiting nut is fixed in the collection box and sleeved on the threaded sleeve, and the limiting nut is threadedly connected to the threaded sleeve; Wherein, the fixing ring is fixedly connected to the threaded sleeve via a fixing rod.

[0017] By adopting the above technical solution, the output shaft of the motor drives the screw to rotate, and under the action of the limit nut, the threaded sleeve moves along the axial direction of the screw, and the fixing ring and the dust collecting plate are driven by the fixing rod to move up and down, thereby achieving effective capture of dust at different heights; When the threaded sleeve moves downward, the threaded sleeve drives the dust collecting plate to move downward to the extreme position. According to the set time, the controller controls the water pump to start, and the water gun flushes the dust collecting plate. After flushing, the motor reverses and drives the threaded sleeve to move upward, so that the dust collecting plate collects dust again, thereby making it easy to ensure that the dust collecting part can effectively capture the dust entering the collection box, thereby improving the dust removal efficiency.

[0018] Optionally, a stirring component is also included, and the stirring component includes: A cleaning box is fixedly mounted on the vehicle body and is connected to the collection box through a guide tube; A connecting rod, coaxially connected to the threaded sleeve and located in the guide tube; There are multiple groups of stirring rods, which are arranged around the axis of the connecting rod. Each group of stirring rods is arranged along the axis of the connecting rod. The stirring rods are located in the cleaning box.

[0019] By adopting the above technical scheme, the water gun forms a dust-containing water flow for dust reduction, and flows into the cleaning box through the guide tube, the threaded sleeve drives the connecting rod to rotate, and the connecting rod drives the stirring rod to rotate. Since the threaded sleeve can move up and down, the stirring rod can move up and down with the lifting of the threaded sleeve, thereby realizing the stirring of sewage at different heights in the cleaning box, preventing the sewage from settling and stratification, thereby facilitating sewage discharge and further improving the dust removal effect.

[0020] Optionally, a scraper is fixedly provided on one end of the connecting rod away from the threaded sleeve.

[0021] By adopting the above technical solution, when the threaded sleeve moves downward, the threaded sleeve drives the dust collecting plate to move downward to the extreme position. At this time, the scraper abuts against the bottom wall of the cleaning box, and the scraper disperses the sludge deposited in the cleaning box, thereby facilitating sewage discharge and improving the dust removal effect.

[0022] Optionally, the scraper is tooth-shaped in a direction close to the bottom of the cleaning box.

[0023] By adopting the above technical solution, the toothed scraper can better contact with the bottom of the cleaning box, especially for the sludge attached to the bottom, making the cleaning process more thorough, thereby improving the cleaning efficiency.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting a dust concentration sensor and an adjustment unit, the adjustment unit adjusts the expansion size of the guide plate according to the dust concentration in the tunnel, which can further increase the dust collection area and improve the dust collection efficiency; 2.

By setting up the cleaning box, connecting rod and stirring rod, the sewage at different heights in the cleaning box can be stirred to prevent the sewage from settling and stratification, thereby facilitating sewage discharge and improving the dust removal effect.
