Embodiment 1

[0041] like figure 1 , image 3 As shown, a flight arrester for a carbon dioxide cracker includes a limit reel 2, and the limit reel 2 is sleeved on the flight stop seat 1 for connecting with the cracker and preventing the cracker from flying out. The seat 1 includes a small end 11 arranged in the limit reel 2 and a large end 12 extending out of the limit reel 2 and connected to the small end 11, the small end 11 is connected with the cracker, and the limit roll The tube 2 is cylindrical and is provided with a gap 3 spirally arranged along its surface. The limit reel 2 is parallelogram after unfolding along the gap 3, and the small end 11 and the large end 12 form a circular truncated shape.

[0042] In this embodiment, the flystop includes a limit drum 2, which is cylindrical and is provided with a gap 3 that is spirally arranged along the surface of the limit drum 2, and the limit drum 2 and the small end There is an annular space between the parts 11, which is convenient ...

Embodiment 2

[0046] like figure 1 , image 3 , Figure 7 As shown, a flight arrester for a carbon dioxide cracker includes a limit reel 2, and the limit reel 2 is sleeved on the flight stop seat 1 for connecting with the cracker and preventing the cracker from flying out. The seat 1 includes a small end 11 arranged in the limiting reel 2 and a large end 12 protruding from the limiting reel 2, the small end 11 is connected with the cracker, the limiting reel 2 is cylindrical and It is provided with a slit 3 spirally arranged along the surface of the limit reel 2, and the limit reel 2 is parallelogram after being unfolded along the slit 3, the small end 11 and the large end 12 are cylinders, and the small end 11 The outer diameter is smaller than the outer diameter of the large end portion 12 .

[0047] In this embodiment, both the small end portion 11 and the large end portion 12 are cylinders. When the limiting reel 2 is expanded under pressure, the large end portion 12 is directly rest...

Embodiment 3

[0049] like figure 1 , image 3 , Figure 8 As shown, a flight arrester for a carbon dioxide cracker includes all the structures of Embodiment 2, and also includes: a connecting portion 13 is provided between the small end portion 11 and the large end portion 12, the connecting portion 13 is in the shape of a circular truncated cone, and the connecting portion The outer diameter of the end connected to the small end 11 is the same as that of the small end 11 , and the outer diameter of the end connected to the large end 12 of the connecting portion 13 is the same as that of the large end 12 .

[0050] In this embodiment, when the limiting reel 2 is expanded under pressure, the connecting part 13 and the large end 12 are restricted by the limiting reel 2 and are stuck outside the limiting reel 2 and cannot continue to move upwards. The setting of the part 13 plays a buffering role, thereby effectively preventing the cracker from flying out towards the blasting hole, avoiding ...

Abstract

The invention belongs to the technical field of explosion safety devices, and provides a flying stopper for a carbon dioxide actuator. The flying stopper comprises a limiting winding drum, the limiting winding drum is arranged on a flying stopping seat which is used for being connected with a fracturing device and preventing the fracturing device from flying out, the fracturing device comprises asmall end part and a large end part, wherein the small end part is arranged in the limiting winding drum, the large end part extends out of the limiting winding drum, and the small end part is connected with the fracturing device. The invention further provides a carbon dioxide fracturing device, the carbon dioxide fracturing device comprises a fracturing device body, the fracturing device body isconnected with the flying stopper, the fracturing device body comprises an air release head, a liquid storage tube and an inflation head which are connected in sequence, one end, away from the liquidstorage tube, of the air release head is connected with the flying stopping seat, an opening is formed in the air release head, a hollow cavity is formed in the liquid storage tube, and an energy release sheet is arranged at one end, connected with the air release head, of the hollow cavity. According to the flying stopper for the carbon dioxide actuator, the problems that the flying stopper is complex in structure, inconvenient to use and low in flying stopping effect in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of blasting devices, and relates to a fly arrestor and a cracker for a carbon dioxide cracker. Background technique [0002] The carbon dioxide cracker uses liquid carbon dioxide to rapidly gasify and expand when it becomes hot, causing the gas pressure to rise sharply. When the pressure exceeds the set pressure of the energy release plate, the high-pressure gas breaks through the energy release plate and is released from the vent port, creating a powerful impact instantly Force, along the natural cracks of coal, rock mass and other materials or the crack surface caused by blasting to break the material, and push it away from the main body, so as to achieve the purpose of blasting. The carbon dioxide cracker has no destructive vibration and shock wave during the blasting process, the proportion of dust is reduced, and it has little impact on the surrounding environment. It can replace explosives and be used ...
