[0010] In the present invention, the CO elimination mechanism is a multi-layer annular structure composed of a first charging barrel, a second charging barrel and a third charging barrel. At the same time, an outer annular ventilation area is formed between the first charging barrel and the second charging barrel, and an inner annular ventilation area is formed between the second charging barrel and the third charging barrel, so that the detonation gas can pass through the CO elimination mechanism smoothly through the outer annular ventilation area and the inner annular ventilation area. Since the first, second and third charging barrels are respectively filled with CO eliminator particles A, B and C, and at the same time, through holes are arranged on the barrel of each charging barrel, in this way, during the process of the detonation gas passing through the CO elimination mechanism, it can fully contact with the CO eliminator particles in the three charging barrels, so that the CO gas contained in the gas can be effectively eliminated by using the CO eliminator particles, and the purpose of quickly and efficiently removing toxic and harmful gases is achieved. The movable end cover is detachably covered on the right open end of the main barrel, which can facilitate opening or closing the movable barrel, and then it can facilitate loading or removing the CO elimination mechanism into or out of the movable barrel. The movable cylinder is provided with a plurality of through holes, so that the detonation gas can pass through the movable cylinder and enter the CO elimination mechanism smoothly. The second support plate is axially slidably mounted on the outer side of the movable cylinder through the circular hole in the center thereof. At the same time, a plurality of support rods surrounding the outer periphery of the movable cylinder are used to connect the second support plate and the first support plate located on the left side of the movable cylinder, so that a protection frame can be formed on the outer periphery of the movable cylinder. In this way, not only the movable cylinder can be protected, but also the movable cylinder can slide relative to the protection frame in the axial direction. The connecting screw sleeve is connected to the right side of the first support plate, and the connecting stud is connected to the left side of the connecting cover. It is convenient to fix the connecting cover between the first support plate and the movable cylinder through threaded matching, and then the movable cylinder is connected to the connecting cover by using a plurality of first elastic connecting components. While the supporting frame is used to protect the movable cylinder, a buffer force is provided for the axial movement process of the movable cylinder through the plurality of first elastic components, thereby improving the protection effect of the movable cylinder.

In this way, when the elimination system is pushed toward the bottom of the blasthole, it can be ensured that the fixing pins can extend outward by a certain length, and can be smoothly inserted into the wall of the rock under the limiting effect of the limiting baffle, which is conducive to fixing the elimination system inside the blasthole. Combined with the buffering protection effect of the plurality of elastic components, the elimination system can be equipped with the ability to resist the blasting pressure and shock wave of the explosive. At the same time, by using a plurality of first elastic components evenly distributed in the annular direction to connect the connection cover and the movable cylinder body, by using a plurality of second elastic components evenly distributed in the annular direction to connect the front end plate and the connection cover, and by using a plurality of third elastic components evenly distributed in the annular direction to connect the movable end cover and the rear end plate, the load-bearing capacity can be effectively enhanced by a parallel connection method, and at the same time, a good pressure relief and buffering effect can be achieved, which is conducive to multiple protections for the elimination system, and the elimination system has the ability to be reused. Furthermore, when the elimination system is fixed inside the blast hole, it can also help prevent the occurrence of punching, which helps to improve the blasting effect to a certain extent. In addition, during the blasting process, the CO elimination mechanism placed in the blast hole can effectively remove CO from the gas, achieving the effect of eliminating CO from the source.

[0011] The system has an ideal CO elimination effect and high elimination efficiency. At the same time, it has strong impact resistance and self-protection ability. It can eliminate the CO generated during the operation from the source, which is beneficial to improving operation efficiency and ensuring the health and safety of workers.

At this time, the first elastic component 35, the second elastic component 36 and the third elastic component 40 are all in a compressed state, and then the plug 46 is blocked at the orifice of the blast hole 45; at the moment when the explosive 44 explodes, the detonation gas generated impacts the front end plate 32; in this process, the plurality of second elastic components 36 and the plurality of third elastic components 40 buffer the explosion impact force received by the elimination system as a whole, and the plurality of first elastic components 35 and the third elastic components 40 slidingly matched with the movable cylinder 11 are used to reduce the impact of the explosion. The second support plate 18 and the multiple fixing pins 28 anchored in the hole wall are used to further buffer the impact force on the movable cylinder 11; at the same time, the detonation gas enters the interior of the movable cylinder 11 through the several through holes 6 41 on the front end plate 32, the circular hole 1 20 and the several through holes 4 23 on the first support plate 17, the circular hole 3 37 and the several through holes 5 38 on the connecting cover 33, the several through holes 1 on the main cylinder 12 and the several through holes 2 on the fixed end cover 13 in sequence, and fully contacts with the first charging cylinder 4, the second charging cylinder 5 and the third charging cylinder 6, and then, the CO eliminator particles A, the CO eliminator particles B and the CO eliminator particles C inside the first charging cylinder 4, the second charging cylinder 5 and the third charging cylinder 6 fully act on the CO in the gas, realizing the efficient elimination operation of CO in the gas, wherein the gas after the CO is eliminated flows toward the orifice direction through the several through holes 3 16 on the movable end cover 14 and the several through holes 7 42 on the rear end plate 34.

[0025] In the present invention, the CO elimination mechanism is a multi-layer annular structure composed of a first charging barrel, a second charging barrel and a third charging barrel. At the same time, an outer annular ventilation area is formed between the first charging barrel and the second charging barrel, and an inner annular ventilation area is formed between the second charging barrel and the third charging barrel, so that the detonation gas can pass through the CO elimination mechanism smoothly through the outer annular ventilation area and the inner annular ventilation area. Since the first, second and third charging barrels are respectively filled with CO eliminator particles A, B and C, and at the same time, through holes are arranged on the barrel of each charging barrel, in this way, during the process of the detonation gas passing through the CO elimination mechanism, it can fully contact with the CO eliminator particles in the three charging barrels, so that the CO gas contained in the gas can be effectively eliminated by using the CO eliminator particles, and the purpose of quickly and efficiently removing toxic and harmful gases is achieved. The movable end cover is detachably covered on the right open end of the main barrel, which can facilitate opening or closing the movable barrel, and then it can facilitate loading or removing the CO elimination mechanism into or out of the movable barrel. The movable cylinder is provided with a plurality of through holes, so that the detonation gas can pass through the movable cylinder and enter the CO elimination mechanism smoothly. The second support plate is axially slidably mounted on the outer side of the movable cylinder through the circular hole in the center thereof. At the same time, a plurality of support rods surrounding the outer periphery of the movable cylinder are used to connect the second support plate and the first support plate located on the left side of the movable cylinder, so that a protection frame can be formed on the outer periphery of the movable cylinder. In this way, not only the movable cylinder can be protected, but also the movable cylinder can slide relative to the protection frame in the axial direction. The connecting screw sleeve is connected to the right side of the first support plate, and the connecting stud is connected to the left side of the connecting cover. It is convenient to fix the connecting cover between the first support plate and the movable cylinder through threaded matching, and then the movable cylinder is connected to the connecting cover by using a plurality of first elastic connecting components. While the supporting frame is used to protect the movable cylinder, a buffer force is provided for the axial movement process of the movable cylinder through the plurality of first elastic components, thereby improving the protection effect of the movable cylinder. The front end plate and the rear end plate are relatively arranged at the leftmost and rightmost positions, and a plurality of second elastic components are used to connect the front end plate and the first support plate, and a plurality of third elastic components are used to connect the rear end plate and the second support plate. The second elastic components and the third elastic components can cooperate to provide elastic forces for the movable cylinder and the support frame, thereby effectively buffering the impact force during the blasting process, thereby effectively protecting the CO elimination mechanism and the movable fixing mechanism.The outer ends of the plurality of fixing pins are all of a pointed cone structure, and at the same time, the inner ends of the fixing pins are movably connected to the main cylinder body through a hinge block, and the fixing pins of the elastic components are in an inclined state under normal conditions. In this way, when the elimination system is pushed toward the bottom of the blasthole, it can be ensured that the fixing pins can extend outward by a certain length, and can be smoothly inserted into the wall of the rock under the limiting effect of the limiting baffle, which is conducive to fixing the elimination system inside the blasthole. Combined with the buffering protection effect of the plurality of elastic components, the elimination system can be equipped with the ability to resist the blasting pressure and shock wave of the explosive. At the same time, by using a plurality of first elastic components evenly distributed in the annular direction to connect the connection cover and the movable cylinder body, by using a plurality of second elastic components evenly distributed in the annular direction to connect the front end plate and the connection cover, and by using a plurality of third elastic components evenly distributed in the annular direction to connect the movable end cover and the rear end plate, the load-bearing capacity can be effectively enhanced by a parallel connection method, and at the same time, a good pressure relief and buffering effect can be achieved, which is conducive to multiple protections for the elimination system, and the elimination system has the ability to be reused. Furthermore, when the elimination system is fixed inside the blast hole, it can also help prevent the occurrence of punching, which helps to improve the blasting effect to a certain extent. In addition, during the blasting process, the CO elimination mechanism placed in the blast hole can effectively remove CO from the gas, achieving the effect of eliminating CO from the source.

[0026] The system has an ideal CO elimination effect and high elimination efficiency. At the same time, it has strong impact resistance and self-protection ability. It can eliminate the CO generated during the operation from the source, which is beneficial to improving operation efficiency and ensuring the health and safety of workers.
