Description

Technical Field

[0001] This invention relates to the technical field of dust suppression methods for blasting in mines, specifically to a dust suppression method for blasting in open-pit mines. Background Technology

[0002] In mining operations, a large number of blasting operations are required, and the dust generated during the blasting process is one of the sources of dust in mines. Mines generally remove dust through natural ventilation or forced ventilation. This method blows the dust into the natural environment, which reduces the dust concentration in the mine, but causes air pollution to the surrounding environment. In order to solve the above problems, this invention proposes a dust reduction method for blasting in open-pit mines. Summary of the Invention

[0008] A. Sprinkle water in the area to be blasted to make the mine surface moist;

[0009] B. Drill blast holes and fill them with explosives, packing materials, and water-based blasting mud.

[0010] C. After detonation, manually push in the water spraying equipment to spray and suppress dust.

A storage box is fixedly arranged on the side surface of the movable block away from the push plate. Two first magnets are fixedly arranged at the top of the storage box. Two second magnets are arranged on both sides of the top surface of the filter screen so as to be reciprocally movable. The two first magnets and the two second magnets are opposite to each other in the thickness direction of the filter screen.

[0017] A push handle is fixedly installed on the side of the water storage tank.

[0018] (3) Beneficial effects:

[0019] 1. The atomizing nozzle is rotated to a preset angle, and then the water pump is started, which introduces water into the atomizing nozzle through a steel pipe. Water mist is then sprayed out to suppress dust. The angle and position of the water mist can be adjusted at any time by the motor, so that water mist can be used to suppress dust without polluting the surrounding environment.

[0020] 2. The filter screen can block impurities that fall into the water tank from entering the water pipe and prevent them from entering the atomizing nozzle 4 and causing damage to the atomizing nozzle.

[0021] 3. After the first cylinder, carrying multiple pins, clears the filter and then resets, the second cylinder starts resetting again, moving the flip plate downwards. When the flip plate separates from the backing plate, it returns from a vertical to a horizontal position under the action of the torsion spring. As the flip plate moves downwards, it pushes the impurity particles that were not completely pushed into the storage box by the pins into the storage box. This prevents too many impurity particles from getting stuck on the first and second rubber plates, which would cause the gap between the first and second rubber plates to become too large. This would allow the impurity particles pushed between the first and second rubber plates to be discharged from the storage box with the water flow again, thus failing to isolate the impurity particles and prevent them from falling out of the storage box. This also prevents impurity particles from being discharged from the storage box again, repeatedly clogging the filter and affecting the water discharge, thereby affecting the efficiency of the spray dust suppression work.

A baffle plate 666 is fixedly arranged on the top of the storage box 41. The gap between the first rubber plate and the second rubber plate is smaller than the gap of the impurity particles, so as to block the impurity particles in the storage box 41.

[0049] Guide rails 501 are respectively fixedly arranged on both sides of the steel pipe 6. Trapezoidal blocks 502 are respectively fixedly arranged on both upper ends of the moving plate 40. The trapezoidal blocks 502 are located inside the guide rails 501. A return spring 503 is fixedly arranged between the inner wall of one end of the guide rail 501 away from 29 and the trapezoidal block 502.

[0050] The inner wall of the water storage tank 1 is provided with a movable cavity 50. The inner wall of the feed channel 47 has two extension slots 510. The two extension slots 510 are located on the same side wall as the first rubber plate 48. The first rubber plate 48 has two notched slots 149. One side opening of the two extension slots 510 is directly opposite the two notched slots 149, and the other side opening is connected to the movable cavity 50. Two second cylinders 51 are fixedly installed at the bottom of the movable cavity 50, and the two second cylinders 51 are respectively located on both sides of the bottom of the movable cavity 50.

[0052] A push handle 401 is fixedly installed on the side of the water storage tank 1.

[0053] The diameter of the fourth bevel gear 30 is three times that of the third bevel gear 27, which reduces the rotational speed of the push plate 31 and thus reduces the moving speed of the storage box 41, allowing enough time for the filter screen to be cleared.

[0054] The pin 46 has a first infrared sensor, which is connected to the first cylinder 44. The two stroke plates 52 have second infrared sensors, which are connected to the second cylinder. The infrared sensors can determine whether the filter holes on the filter screen are blocked by foreign objects. If blocked, the second cylinder will be started first, and then the first cylinder will be started.

[0055] Figure 15 588 in the diagram represents impurity particles.

[0056] The working principle of this invention is as follows: The water tank 1 is filled with water, the motor 133 is started, which drives the atomizing nozzle 4 to rotate to a preset angle. Then the water pump 2 is started, and water enters the atomizing nozzle 4 through the steel pipe 6. Water mist is then sprayed out to suppress dust. At the same time, the angle of the water mist can be adjusted at any time by the motor 133. The filter screen can block impurities that fall into the water tank from entering the water pipe and prevent them from entering the atomizing nozzle 4 and causing damage to the nozzle.

[0057] When water flows through the steel pipe 6, it drives the fan wheel 23 to rotate. The fan wheel 23 drives the first bevel gear 24 to rotate, which in turn drives the second bevel gear 26 to rotate. The second bevel gear 26 drives the third bevel gear 27 to rotate, which in turn drives the push plate 31 to rotate. When the push plate 31 rotates to the position where it contacts the moving block 40, it pushes the moving block 40 to move to the right. The movement of the moving block 40 moves the first magnet 42 along with it. The movement of the first magnet 42, through magnetic attraction, drives the second magnet 43 to move along with it. The second magnet 43, in turn, moves the pin 46 along with it. When the pin 46 moves onto the filter screen... When filtering, if both the second and first infrared sensors detect blockage in the filter holes, the second cylinder 51 will be activated first. The second cylinder 51 will move the stroke plate 52 upwards, which in turn moves the tilting plate 53 upwards. When the pressing plate 57 contacts the abutment plate 60, the pressing plate 57 will tilt, rotating the rotating rod 55 and the tilting plate 53 by 90°. When the second cylinder 51 moves the tilting plate 53 to its highest position, the upper side of the tilting plate 53 will abut against the filter screen, and then tilt upwards to a vertical position (i.e.,...) via the baffle plate 666. Figure 9 The leftmost flip plate 53 is flipped upwards by 90° to form a sealed space. Then, the first cylinder 44 is activated, which drives multiple pins 46 to move downwards to clear the filter holes on the filter screen. The pins 46 push the dislodged impurity particles to the bottom of the first rubber plate 48 and the second rubber plate 49. Since the gap between the first rubber plate 48 and the second rubber plate 49 is smaller than the size of the impurity particles, it can prevent the impurity particles from passing through the gap between the first rubber plate 48 and the second rubber plate 49 from the storage box 41 and returning to the water tank to block the filter screen. When the impurity particles are pushed through the gap between the first rubber plate 48 and the second rubber plate 49 into the storage box 41 by the multiple pins 46, the first rubber plate 48 and the second rubber plate 49 will deform due to sufficient extrusion pressure, so the impurity particles can pass through the first rubber plate 48 and the second rubber plate 49 into the storage box 41.

[0058] After the first cylinder 44, carrying multiple pins 46, clears the filter screen and then resets, the second cylinder 44 starts resetting again, moving the flip plate 53 downwards. When the flip plate 53 separates from the back plate 60, the flip plate 53 returns from a vertical to a horizontal state under the action of the torsion spring. As the flip plate 53 moves downwards, it pushes the impurity particles that were not completely pushed into the storage box 41 by the multiple pins 46 into the storage box 41. This prevents too many impurity particles stuck on the first rubber plate 48 and the second rubber plate 49, which would make the gap between the first rubber plate 48 and the second rubber plate 49 too large. This would allow the impurity particles pushed between the first rubber plate 48 and the second rubber plate 49 to be discharged from the storage box 41 again with the water flow, thus failing to isolate the impurity particles and prevent them from falling out of the storage box 41. This also prevents impurity particles from being discharged from the storage box again, repeatedly clogging the filter screen, repeatedly affecting the water discharge, and thus affecting the working efficiency of the spray dust suppression.

Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
