Description

Technical Field

[0001] This utility model relates to the field of liquid oxygen rock crushing technology, and in particular to a liquid oxygen rock crushing ignition head. Background Technology

[0002] In the field of liquid oxygen rock breaking, traditional detonation devices typically use chemical agents such as sodium chlorate, potassium chlorate, or potassium perchlorate as igniters. Their working principle involves igniting these chemicals by heating them with an electric current, thus achieving detonation. However, this existing technology has several drawbacks: First, safety is compromised. The chemical agents used are highly susceptible to static electricity or stray currents, which can easily ignite them, leading to premature detonation and potentially serious safety accidents. Second, ignition performance is unstable. Due to variations in the dosage of chemical agents in the igniter, the rate of temperature rise after ignition differs, making it difficult to effectively control the detonation delay time and affecting the accuracy of the breaking operation. Third, environmental adaptability is poor. In extreme environments such as high humidity and high pressure, the performance of the chemical agent igniter fluctuates, making it difficult to guarantee a stable detonation effect. Fourth, raw material availability is limited. Given that these chemical agents are hazardous chemicals, their use is subject to strict controls, leading to difficulties in obtaining materials and restricting the application and development of related technologies.

[0003] Therefore, in order to improve the ignition and detonation performance of liquid oxygen rock breaking, there is an urgent need to develop a safer, more reliable and efficient ignition device. Utility Model Content

[0004] This invention provides a liquid oxygen rock crushing ignition head to solve the problem of poor ignition and detonation performance of traditional liquid oxygen rock crushing.

[0005] To solve the above-mentioned technical problems, embodiments of this utility model provide a liquid oxygen rock crushing ignition head, comprising:

[0006] Tungsten wire is used as the ignition head body to replace the chemical agent for breaking rocks with liquid oxygen.

[0007] Two wires, one end of which is electrically connected to the two ends of the tungsten wire, and the other end of which is connected to an external power source, to form a complete power-carrying heating circuit, through which the tungsten wire is powered by the external power source via the wires;

[0008] The paper roll has tungsten wires attached and wound onto it, or the paper roll is attached and wrapped around the tungsten wires, so that the heat from the tungsten wires can be quickly transferred to the paper roll after it conducts electricity and generates heat.

[0009] In the aforementioned ignition head, the paper roll is a cylindrical or tubular structure with a diameter of 8-12mm and a length of 35-45mm, and the tungsten wire is spirally wound around the outer surface of the paper roll;

[0010] In the aforementioned ignition head, the tungsten filament is bound or wrapped around the paper roll by a thermally conductive insulating film. The thermally conductive insulating film has openings distributed on it. The thermally conductive insulating film is made of a material that is resistant to high temperatures, has good insulation properties, and has a certain thermal conductivity, such as PET insulating sheet / film, also known as Mylar sheet. The common thickness is between 0.1-0.5mm, and the temperature resistance can reach 130 degrees. When the paper roll is burning, it can also burn or deform at the same time, avoiding the paper roll being constantly wrapped and thus affecting the ignition of the paper roll. At the same time, it is affordable and can ensure that the heat generated by the tungsten filament is efficiently focused and transferred to the paper roll, while preventing current leakage and ensuring safe use.

[0011] In the aforementioned ignition head, the diameter of the tungsten wire is 0.1-0.8 mm;

[0012] In the aforementioned ignition head, a protective shell can also be installed on the outside of the tungsten filament. The protective shell is made of high-strength, low-temperature resistant materials, such as stainless steel. Its shape is adapted to the inside of the liquid oxygen storage tube, which can provide physical protection for the ignition head and prevent it from being damaged by collisions during installation and use. In addition, the protective shell is equipped with vent holes to ensure that the gas generated by the reaction between liquid oxygen and paper roll can be discharged smoothly.

[0013] In the aforementioned ignition head, the outer side of the protective shell may also be covered with a waterproof membrane.

[0014] Compared with existing technologies, this invention applies tungsten wire to the ignition device of liquid oxygen storage pipes in the field of liquid oxygen rock crushing, replacing the chemical ignition head material and eliminating the use of hazardous chemicals. By utilizing the high melting point, high conductivity, and rapid heating characteristics of tungsten wire, it significantly improves the safety, reliability, response speed, and environmental adaptability of liquid oxygen rock crushing ignition and detonation. It solves the problems of difficult raw material acquisition and poor safety from the source, opening up a new development direction for liquid oxygen rock crushing ignition technology and has important technological innovation significance and application value.

[0015] Through a unique spiral structure design, tungsten wire is wound around a paper roll, significantly increasing the contact area between the tungsten wire and the toilet paper roll. This structural design allows the heat generated by the tungsten wire to be transferred to the paper roll more quickly and evenly, effectively improving the efficiency of igniting liquid oxygen and the toilet paper roll, and ensuring the timeliness and reliability of ignition and detonation. Simultaneously, the added thermally conductive insulation layer and protective shell further optimize the device's performance. The thermally conductive insulation layer improves safety and heat retention, enhances ignition efficiency, and reduces the risk of leakage. The protective shell enhances the device's physical protection and environmental adaptability, achieving multiple structural innovations and providing greater support for the promotion and application of liquid oxygen rock breaking.

[0023] like Figures 1 to 3 As shown, an embodiment of this utility model provides a liquid oxygen rock breaking ignition head, which may include:

[0024] Tungsten wire 1, with a diameter of 0.1-0.8mm, is used as the ignition head body to replace the chemical agent for breaking rocks with liquid oxygen.

[0025] Two wires 2, one end of which is electrically connected to both ends of the tungsten wire, and the other end of which is connected to an external power source to form a complete power-conducting heating circuit, through which the tungsten wire 1 is powered by the external power source via the wires 2;

[0026] Paper roll 3 is a columnar or cylindrical structure with a diameter of 8-12mm and a length of 35-45mm. Tungsten wire 1 is spirally wound on the outer surface of paper roll 3 so that the heat can be quickly transferred to paper roll 3 after the tungsten wire 1 conducts electricity and generates heat.

[0027] A thermally conductive insulating film 4 is wrapped around the outside of the tungsten wire 1. The thermally conductive insulating film 4 has openings to allow air to pass through. The thermally conductive insulating film 4 is made of a material that is resistant to high temperature, has good insulation performance and has a certain thermal conductivity, such as PET insulating sheet / film, also known as Mylar film (named after the American DuPont brand MYLAR film). The common thickness is between 0.1-0.5mm, and the temperature resistance can reach 130 degrees. When the paper roll is burning, it can also burn or deform at the same time, avoiding the paper roll 3 being always wrapped and affecting the ignition of the paper roll 3. At the same time, it is affordable. It can ensure that the heat generated by the tungsten wire is efficiently focused and transferred to the paper roll 3, and prevent current leakage, ensuring safe use.

[0028] The tungsten filament 1 can also be fitted with a protective shell. The protective shell is made of high-strength, low-temperature resistant materials, such as stainless steel. Its shape is adapted to the inside of the liquid oxygen storage tube, which can provide physical protection for the ignition head and prevent it from being damaged by collisions during installation and use. The protective shell is also equipped with vent holes to ensure that the gas generated by the reaction between liquid oxygen and paper roll can be discharged smoothly. The outer side of the protective shell can also be covered with a waterproof membrane. The waterproof membrane does not completely cover the ignition head, leaving a venting area or vent holes.

[0029] The specific preparation steps in this embodiment may include:

[0030] 1. Material preparation:

[0031] First, prepare a tungsten wire 1 with a length of approximately 10cm-12cm and a diameter of 0.1mm-0.8mm;

[0032] Take 35mm-45mm long toilet paper and roll it into a paper roll 3 with a diameter of 9mm-12mm. During the rolling process, ensure that the paper roll is tight and uniform, and avoid looseness or uneven thickness, so as to ensure the stability of the subsequent winding of tungsten wire 1 and the consistency of the ignition effect.

[0033] Prepare a 0.5 square millimeter copper core red and black wire 2 (double wire). Copper core wire has good conductivity and flexibility. The red and black color makes it easy to distinguish the positive and negative poles, which is convenient for subsequent circuit connection. At the same time, prepare an appropriate amount of soldering materials, such as solder wire and flux, for soldering tungsten wire 1 and wire 2.

[0034] 2. Tungsten filament igniter head fabrication:

[0035] Weld one end of the prepared tungsten wire 1 to one of the copper core red and black wires, and wind it into a spiral shape on the paper roll 3. Weld the other end to another copper core red and black wire 2.

[0036] If it is necessary to cover the thermally conductive insulating film 4, then the thermally conductive insulating film 4 can be wrapped around the tungsten wire 1 and the paper roll 3.

[0037] One-end soldering: Using a soldering iron, solder one end of the prepared tungsten wire 1 to one of the copper core red and black wires. Before soldering, clean the connection area between the tungsten wire 1 and the wire 2 to remove the oxide layer and impurities. Then apply an appropriate amount of flux to improve the soldering quality. During soldering, control the temperature of the soldering iron and the soldering time to ensure a firm and smooth solder joint, avoiding problems such as cold solder joints or detachment.

[0038] Winding: The welded tungsten wire 1 is wound into a spiral shape on the paper roll 3. During the winding process, the spacing of the tungsten wire 1 should be kept uniform, and it should be tightly attached to the surface of the paper roll 3 to increase the contact area between the tungsten wire 1 and the toilet paper roll, thereby improving the ignition efficiency. The spiral structure design not only increases the effective heating length of the tungsten wire 1, but also allows the heat to be transferred more evenly to the paper roll 3, promoting the reaction between liquid oxygen and the paper roll 3.

[0039] Soldering the other end: After winding, solder the other end of the tungsten wire 1 to the other copper core red and black wire 2 using a soldering iron, ensuring a complete circuit connection. After soldering, inspect the entire ignition head to check if the solder joints are secure and if the tungsten wire 1 is broken or damaged. Repair any problems promptly.

[0040] Auxiliary structure installation: After connecting the tungsten wire 1 and the wire 2, wrap the thermally conductive insulation layer 4 around the wound tungsten wire 1 and paper roll 3, ensuring a tight wrap. Then, place the assembled ignition head into the protective shell, adjust its position, and ensure that the vent holes of the protective shell are unobstructed. Finally, when using it for ignition, fix the protective shell inside the liquid oxygen pipe. At this point, the liquid oxygen rock-breaking tungsten wire ignition head is complete.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
