Description

Technical Field

[0001] The utility model relates to the technical field of blasting dust reduction, in particular to an assembled dust reduction device based on water bag plugging. Background Technique

[0002] With the regularization of blasting and the research on mine exploitation by people, more and more blasting methods and techniques have been researched and developed. Blasting is a method of breaking, dividing or removing targets through explosives, gas blasting, water pressure blasting, etc., and is usually used in fields such as mining, construction, and demolition. The principle of the blasting method is to insert explosives, compressed gas, water or other blasting substances into the interior of an object for detonation, and use the shock wave and high-temperature and high-pressure gas generated by the explosion to damage or remove the target. However, a large amount of smoke and dust will be generated during the blasting process. These smoke and dust will cause serious pollution to the environmental atmosphere and cause serious harm to the human body after being inhaled by humans. Therefore, it is necessary to limit the generation of smoke and dust during blasting and reduce the flying of blasting smoke and dust. Content of the Utility Model

[0003] The purpose of the utility model is to provide an assembled dust reduction device based on water bag plugging to solve the problem of the flying of smoke and dust generated during blasting mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An assembled dust reduction device based on water bag plugging, including a blasting cylinder body, the blasting cylinder body is buried inside the rock mass, and one end of the blasting cylinder body is threadedly installed with a dust reduction outer shell, and the dust reduction outer shell and the blasting cylinder body are concentrically designed. The end of the dust reduction outer shell away from the blasting cylinder body is threadedly installed with a top cover, and a water outlet is penetrated through the outer surface of the top cover, and the water outlet is arranged in a circular pattern with the top cover as the center. The top cover and the dust reduction outer shell are concentrically designed. The interior of the dust reduction outer shell and the top cover is filled with a water bag, and a filling, inserting and spraying mechanism is arranged inside the dust reduction outer shell and the top cover. The water in the water bag is squeezed out by the blasting force generated by the blasting cylinder body for dust reduction.

[0005] Preferably, the filling, inserting and spraying mechanism includes: a water outlet hole, the side surface of the water outlet hole is evenly provided with water outlet holes, and the water outlet holes are inclined. A filling through hole is arranged inside the dust reduction outer shell and the top cover, and the filling through hole and the dust reduction outer shell and the top cover are concentrically designed, and the side surfaces of the dust reduction outer shell and the top cover are attached to the water bag. An annular groove is arranged on the side surface of the water bag, and one end of the water bag is attached to the inner surface of the top cover. A water dividing cone is arranged inside the water outlet hole, and the water dividing cone is located on the side of the water outlet hole away from the water bag.

[0006] With the above technical solution, when the blasting cylinder explodes, the blasting cylinder will generate a thrust to push out the sliding plug and break the water bladder bag, causing the water bladder bag to crack along the annular groove. The water in the water bladder bag will be ejected from the water outlet hole through the extrusion of the sliding plug and dispersed by the water distribution cone, making the ejected water fly upward, prolonging the time when the water mist stays in the air. At the same time, the reverse thrust of the water sprayed out by the dust suppression housing reduces the probability of the dust suppression housing flying out, increases the contact with the smoke and dust after blasting, and reduces the scattering of the smoke and dust.

[0007] Preferably, a recessed card slot is fixedly installed inside one end of the top cover away from the dust suppression housing, and the recessed card slot is concentric with the top cover. Plane grooves are evenly formed on the side surface of the top cover, and a water outlet is formed at one end of the top cover away from the plane grooves, and the water outlet does not penetrate the recessed card slot.

[0008] With the above technical solution, after the blasting cylinder explodes, it will push the sliding plug to move inside the dust suppression housing, and finally completely push the broken water bladder bag into the top cover, and squeeze and fix the extruded water bladder bag through the recessed card slot. At the same time, the remaining water is discharged through the water outlet. After that, when recycling, the top cover can be unscrewed from the dust suppression housing, and the residues of the sliding plug and the water bladder bag can be taken out.

[0009] Preferably, a fixed sliding mechanism is arranged between the outer surface of the dust suppression housing and the rock mass. Through the fixed sliding mechanism, the blasting cylinder and the dust suppression housing will not fly out due to the thrust generated by the blasting during blasting.

[0010] With the above technical solution, the thrust generated by the blasting of the blasting cylinder on the dust suppression housing can be reduced, and the dust suppression housing is restricted outside the blast hole.

[0011] Preferably, the fixed sliding mechanism includes: a bracket. A bolt is installed through the outer surface of the bracket, and the side surface of the bolt is attached to the side surface of the bracket. One end of the bolt is embedded in the hole drilled in the rock mass. The dust suppression housing is installed through the outer surface of the bracket, and the side surface of the dust suppression housing is attached to the side surface of the bracket, and the bracket and the dust suppression housing are slidably connected. A retaining piece is slidably installed on the side surface of the dust suppression housing, and the retaining piece is located between the bracket and the rock mass, and the side surfaces of the bracket and the retaining piece are engaged.

[0012] With the above technical solution, when the blasting cylinder explodes and generates a thrust, it will be pushed out together with the retaining piece, causing a protrusion to be generated on the side surface of the retaining piece pushed out of the side surface of the dust suppression housing. When the dust suppression housing moves upward, it will engage with the bracket, slowing down the impact force when the dust suppression housing flies out. At the same time, it is convenient to insert the water bladder bag into the filling through hole without being scratched. After blasting, the rock mass fragments can directly take out the bolt and the bracket. At the same time, the through hole drilled by the bolt can make the rock mass easier to fragment.

[0013] Preferably, a sliding convergence mechanism is provided inside the dust-removing housing. After the components are received through the sliding convergence mechanism, the water bladder bag will not be crushed after being inserted.

[0014] With the above technical solution, after the dust-removing housing and the blasting cylinder are rotated and tightened, the water bladder bag will not be punctured by the sharp cone.

[0015] Preferably, the sliding convergence mechanism includes: a sliding plug, which is slidably installed inside the filling through-hole, and the inner wall of the filling through-hole is in sliding friction connection with the sliding plug. A sharp cone is installed through the outer surface of the sliding plug, and a sealing positioning ring is arranged on the side surface of the sharp cone, and the sealing positioning ring is engaged with the sliding plug. The sliding plug and the sharp cone are concentrically designed, and a pushing plug is fixedly installed on the side surface of the sharp cone. The pushing plug is in sliding friction connection with the sliding plug, and the sliding plug is engaged with the pushing plug.

[0016] With the above technical solution, the positions of the sliding plug and the sharp cone can be temporarily fixed through the sealing positioning ring, so that the sharp cone is received inside the sliding plug and will not contact the water bladder bag after installation. When the thrust generated after the blasting cylinder explodes, it will push the sliding plug and the pushing plug, causing the pushing plug to move inside the sliding plug, pushing out the sharp cone, piercing the water bladder bag with the sharp cone, and moving inside the filling through-hole.

[0017] Compared with the prior art, the beneficial effects of the present utility model are: the assembled dust-removing device based on water bag plugging:

[0018] 1. When blasting, it is necessary to insert the blasting cylinder and the dust-removing housing into the blast hole. When the blasting cylinder explodes, it will generate an impact force to push the sliding plug, causing the sliding plug to slide inside the filling through-hole, piercing the water bladder bag with the sharp cone, and spraying water outwards through the water outlet hole along with the pushing of the sliding plug. The water is dispersed by the water dividing cone, and the dispersed water is thrown towards the sky, increasing the contact area with the dust after blasting and reducing the flying of the dust.

[0019] 2. The thrust generated by the explosion of the blasting cylinder will push out the baffle, causing the baffle to extend out of the side surface of the dust-removing housing, so that when the dust-removing housing is displaced due to the impact, it can be engaged with the side surface of the bracket, restricting the movement of the dust-removing housing. At the same time, the inclined design of the water outlet hole and the water outlet can also generate a reaction force when pushing out the water, restricting the displacement of the dust-removing housing, and at the same time, it can quickly insert the dust-removing housing into the bracket, reducing the probability of the dust-removing housing flying out.

[0020] 3. When installing the water bag, the dust reduction housing can be unscrewed, the water bag can be inserted into the interior of the filling through-hole, and then the sliding plug is implanted. The sliding plug and the pointed cone are temporarily fixed by the sealing positioning ring. When the shock wave generated by the explosion pushes the sliding plug and the pushing plug, the pointed cone will be pushed out to pierce the water bag, so that the pointed cone will not protrude from the sliding plug to pierce the water bag, and at the same time, the water bag can be pierced after the blasting cylinder explodes.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1-6, the present utility model provides a technical solution: an assembled dust suppression device based on water bag plugging, which includes a blasting cylinder body 1. The blasting cylinder body 1 is buried inside the rock mass, and one end of the blasting cylinder body 1 is threadedly installed with a dust suppression outer shell 2, and the dust suppression outer shell 2 and the blasting cylinder body 1 are concentrically designed. One end of the dust suppression outer shell 2 away from the blasting cylinder body 1 is threadedly installed with a top cover 3, and a water outlet 16 is penetrated through the outer surface of the top cover 3, and the water outlet 16 is arranged in a circular shape with the top cover 3 as the center. The top cover 3 and the dust suppression outer shell 2 are concentrically designed. The inside of the dust suppression outer shell 2 and the top cover 3 is filled with a water bag 9, and a filling, inserting and spraying mechanism is arranged inside the dust suppression outer shell 2 and the top cover 3. The water in the water bag 9 is squeezed out by the blasting force generated by the blasting cylinder body 1 for dust suppression. The filling, inserting and spraying mechanism includes: a water outlet hole 7. The side surface of the water outlet hole 7 is evenly provided with water outlet holes 7, and the water outlet holes 7 are inclined. The inside of the dust suppression outer shell 2 and the top cover 3 is provided with a filling through hole 11, and the filling through hole 11 and the dust suppression outer shell 2 and the top cover 3 are concentrically designed. And the side surfaces of the dust suppression outer shell 2 and the top cover 3 are attached to the water bag 9. The side surface of the water bag 9 is provided with an annular groove, and one end of the water bag 9 is attached to the inner surface of the top cover 3. A water dividing cone 8 is arranged inside the water outlet hole 7, and the water dividing cone 8 is located on the side of the water outlet hole 7 away from the water bag 9.

[0030] During blasting, the blasting cylinder body 1 needs to be inserted into the blast hole of the rock mass. When the high-pressure gas generated after the explosion of the blasting cylinder body 1, it will push the sliding plug 12 and the pointed cone 15 to move inside the filling through hole 11. The water bag 9 is punctured by the pointed cone 15, and as the sliding plug 12 moves, the water bag 9 is squeezed, so that the water in the water bag 9 is sprayed out of the dust suppression outer shell 2 through the water outlet hole 7 by extrusion, and is dispersed by the water dividing cone 8, so that the sprayed water is scattered into the sky, extending the suspended time of the dispersed water, making the sprayed water fully contact with the dust after blasting, reducing the dust content in the air, and making the dust fall.

[0031] Inside one end of the top cover 3 away from the dust suppression outer shell 2, a concave clamping groove 6 is fixedly installed, and the concave clamping groove 6 and the top cover 3 are concentrically designed. The side surface of the top cover 3 is evenly provided with flat grooves, and a water outlet 16 is arranged at one end of the top cover 3 away from the flat grooves, and the water outlet 16 does not penetrate the concave clamping groove 6.

[0032] As the sliding plug 12 pushes to compress the water bag 9, the remaining outer shell of the water bag 9 will be pushed into the inside of the top cover 3, and the pointed cone 15 can be engaged with it through the concave clamping groove 6 to compress and limit the outer shell of the compressed water bag 9 inside the top cover 3, and the excess water will be sprayed out through the water outlet 16. When the dust suppression outer shell 2 is recycled later, the top cover 3 can be unscrewed from the dust suppression outer shell 2 through the flat surface on the side surface of the top cover 3, and the sliding plug 12 and the pointed cone 15 inside the top cover 3 can be taken out, together with the compressed outer shell of the water bag 9, which is convenient for taking out and reusing the outer shell of the water bag 9.

[0033] A fixed sliding mechanism is provided between the outer surface of the dust - settling housing 2 and the rock mass. Through the fixed sliding mechanism, the blasting cylinder 1 and the dust - settling housing 2 will not fly out due to the thrust generated by blasting during blasting. The fixed sliding mechanism includes: a bracket 4. A bolt 5 is installed through the outer surface of the bracket 4, and the side surface of the bolt 5 is in contact with the side surface of the bracket 4. One end of the bolt 5 is embedded in the hole drilled in the rock mass. The dust - settling housing 2 is installed through the outer surface of the bracket 4, and the side surface of the dust - settling housing 2 is in contact with the side surface of the bracket 4. And the bracket 4 and the dust - settling housing 2 are in sliding connection. A retaining piece 10 is slidably installed on the side surface of the dust - settling housing 2, and the retaining piece 10 is located between the bracket 4 and the rock mass, and the side surfaces of the bracket 4 and the retaining piece 10 are engaged with each other.

[0034] The high - pressure air generated by the explosion of the blasting cylinder 1 will push the retaining piece 10 to move, so that one end of the retaining piece 10 is pushed out of the dust - settling housing 2. After the dust - settling housing 2 is pushed by the high - pressure gas, it can be engaged with the bracket 4 through the retaining piece 10. The tension generated by fixing on the rock mass surface through the bolt 5 restricts the displacement of the dust - settling housing 2. At the same time, the thrust generated by the water sprayed through the water outlet holes 7 and the water outlet 16 reduces the thrust generated when the dust - settling housing 2 is pushed, and reduces the probability of the dust - settling housing 2 flying out of the blast hole.

[0035] A sliding convergence mechanism is arranged inside the dust - settling housing 2. Through the sliding convergence mechanism, the components are stored, so that after the water - filled bag 9 is inserted, the water - filled bag 9 will not be crushed. The sliding convergence mechanism includes: a sliding plug 12. The sliding plug 12 is slidably installed inside the filling through - hole 11, and the inner wall of the filling through - hole 11 and the sliding plug 12 are in sliding friction connection. A tapered cone 15 is installed through the outer surface of the sliding plug 12, and a sealing positioning ring 14 is arranged on the side surface of the tapered cone 15, and the sealing positioning ring 14 is engaged with the sliding plug 12. The sliding plug 12 and the tapered cone 15 are concentrically designed, and a pushing plug 13 is fixedly installed on the side surface of the tapered cone 15. The pushing plug 13 and the sliding plug 12 are in sliding friction connection, and the sliding plug 12 and the pushing plug 13 are engaged with each other.

[0036] When installing the water - filled bag 9, the water - filled bag 9 can be inserted into the filling through - hole 11, so that one end of the water - filled bag 9 abuts against the concave card slot 6. Then, the tapered cone 15 is temporarily fixed inside the sliding plug 12 through the sealing positioning ring 14, so that the tapered cone 15 will not protrude out of the sliding plug 12 and pierce the water - filled bag 9. After that, the sliding plug 12 can be placed into the filling through - hole 11, and the dust - settling housing 2 is screwed onto the blasting cylinder 1. When the blasting cylinder 1 detonates, the sliding plug 12 and the pushing plug 13 will be pushed out together. The tapered cone 15 is pushed out by the pushing plug 13 to pierce the water - filled bag 9, so that the water - filled bag 9 will not be pierced during assembly and will be automatically pierced during blasting.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
