Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The utility model provides a device that synchronous dust removal of blasting aims at improving the dust fall effect, and realizes the technical purpose that the structure is succinct, water conservation nature is good.
Referring to fig. 1, there is shown a blasting synchronous dust removing apparatus,
the blasting synchronous dust removal device is arranged in the direction of the blasting free surface; the method comprises the following steps:

the dedusting water bag 1 is placed on the blasting equipment 2;
the blasting equipment 2 is provided with a lead 3;
the dedusting water bag 1 is closely contacted with the ground 4.
When the lead of the blasting dust-settling device is blasted, the reinforced blasting covering mechanism rapidly expands at high temperature and high pressure, the reinforced airflow impacts and breaks the dust-settling water drum, water is broken into fast jet flow and fine water mist as far as possible, the surface area is greatly enlarged, the probability and the speed of nitrogen oxide capturing reaction are improved, and a good dust-settling effect is achieved. Under the underground blasting working condition, an enhanced blasting covering mechanism can be used in a conditional area, so that water mist is crushed to be finer, more negative ions are contained, the more easily the dust colloid is attracted and combined with positive charges, and after the charges are released, the dust colloid is combined together to be rapidly settled.
Preferably, the dedusting water bag is a sealed water bag.
The water is injected to qualified quantity according to the specified numerical value strictly, and the dedusting water bag can be made of various materials, such as a plastic water bag, a PP material water tank and the like, and the specific material and shape are not limited.
Optionally, the specifications of the blasting equipment and the dedusting water drum are adjusted according to the depth of a blast hole and the type of explosives.
Preferably, the explosive means 3 is one or more small explosive charges.
The blasting equipment can adopt an electric detonator, a detonating cord, a combination of a detonating tube and a detonating bullet, a detonator emulsion explosive or an ammonium nitrate fuel oil explosive and the like, and whether the materials are consistent with the blasting materials in the blasting area or not is not specifically limited.
Preferably, the dedusting water bag is added with dedusting electrostatic agent. The dedusting water bag can be in a single-layer or multi-layer water bag stacking structure.
The dedusting water bag can be added with an antistatic agent, an electrostatic agent or sodium carbonate and the like, so that the dust catching efficiency is enhanced, or the neutralization speed is increased, so that dust or nitrogen oxides actively impact water mist due to the action of charges, and the electricity is released to quickly settle. The effect of no dust or minimum dust emission is achieved, the rapid chemical reaction sedimentation is realized, the generated acid reacts with ground rocks, and the harm to respiratory systems of people and livestock is avoided.
Fig. 2 shows: the utility model discloses a system for synchronous dust removal of blasting, the synchronous dust collector of blasting install in main big gun hole top.
