Description

Technical Field

[0001] The utility model relates to the technical field of liquid explosive production, and more specifically, to a temperature-sensitive static-conductive flow control device for liquid explosive injection. Background Art

[0002] A temperature-sensitive static-conductive flow control device for liquid explosive injection is a safety control device specifically used in the process of liquid explosive injection. It combines temperature-sensitive static-conductive technology and electric control flow technology to ensure the safety and stability of liquid explosives during the injection process.

[0003] First of all, the temperature-sensitive static-conductive technology converts temperature signals into electrical signals through the sensitivity of materials to temperature changes, so as to realize the real-time monitoring and control of the temperature of liquid explosives. This technology helps to prevent potential dangers caused by too high or too low temperatures of liquid explosives, such as explosion or combustion. By combining temperature-sensitive static-conductive technology and electric control flow technology, it realizes the real-time monitoring and control of the liquid explosive injection process, thereby improving the safety and stability of the use of liquid explosives. This device has broad application prospects in the fields of military, civil blasting, mining, etc.

[0004] At present, butterfly valves, ball valves, etc. are used to control the flow rate of liquid substances in the past. However, due to the sensitivity of explosives themselves, high temperatures further increase their friction and impact sensitivity. When using butterfly valves, ball valves, etc. to control their flow rate, the friction and impact generated are extremely likely to cause production safety accidents, and it is not easy to pressurize liquid substances, resulting in poor injection production effects. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a temperature-sensitive static-conductive flow control device for liquid explosive injection, aiming to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A temperature-sensitive static-conductive flow control device for liquid explosive injection, including a support base for support, and a flow guiding assembly is arranged on the support base;

[0007] The diversion assembly includes a heat exchange fin cylinder arranged on the top of the support base. A support shell is arranged in the middle of the heat exchange fin cylinder. A nozzle for conveying materials is arranged in the middle of the support shell. A conveying head is arranged at the bottom of the nozzle. The conveying head penetrates through the support shell and extends to the bottom of the support base. A lining cylinder is arranged in the middle of the nozzle. A number of notches are distributed on the outer side of the lining cylinder. A spring is arranged at the bottom of the lining cylinder. The spring is located inside the nozzle. An upper connecting cover is arranged on the top of the support shell. A diversion joint communicated with the reinforced injection and mixing tank is arranged on the top of the upper connecting cover. A water injection head is arranged on the outer side of the upper connecting cover. A diversion cavity is formed between the nozzle and the support shell and the upper connecting cover, and the water injection head is communicated with the diversion cavity;

[0008] It can be seen that in the above technical solution, when the raw materials are conveyed into the nozzle through the diversion joint and discharged through the conveying head, the raw materials are gathered by the injection nozzle to ensure the conveying density of the raw materials. When the lining cylinder is affected by the raw materials being conveyed into the nozzle, the lining cylinder rotates downward and displaces under pressure while compressing the spring, which is convenient for remixing the raw materials. When the spring resets, it is convenient to block the diversion joint to ensure the accuracy during the conveying of the liquid substance. Cold water is injected into the water injection head through an external pump. It is conveyed to the diversion cavity through the water injection head. When the liquid substance is conveyed in the nozzle, the function of wrapped cooling is realized, which can ensure that the liquid explosive maintains a stable temperature during the injection process, thereby avoiding potential safety risks;

The second toothed cylinder is communicated with the reinforced injection and mixing tank. One end of the first toothed cylinder extends to the eccentric disc. The second toothed cylinder is rotatably connected with the reinforced injection and mixing tank. A pressure relief valve is arranged on the outer side of the reinforced injection and mixing tank, and one end of the pressure relief valve extends to the outer side of the eccentric disc. The pressure relief valve is slidably connected with the reinforced injection and mixing tank;

[0010] It can be seen that in the above technical solution, the raw materials are transported into the enhanced liquid injection mixing tank through the injection pipe orifice. The driving motor drives the first gear cylinder to rotate. When the first gear cylinder rotates, it drives the eccentric disk to rotate, and then drives multiple stirring rods to rotate, realizing the function of mixing the raw materials in the enhanced liquid injection mixing tank. At the same time, when the outer side of the eccentric disk contacts the pressure relief valve, the pressure relief valve will relieve the excess pressure in the enhanced liquid injection mixing tank, and the raw materials can be pushed into the diversion joint by the eccentric disk, making the density of the raw materials higher when being discharged. Through the way that the rotation of the eccentric disk drives the stirring rods to rotate and displace, the stirring rods can be successively inserted into the inner wall of the mixer, realizing the functions of extruding and pushing the liquid substance.

[0012] The technical effects and advantages of the present utility model:

[0013] 1. In the present utility model, the raw materials are transported into the enhanced liquid injection mixing tank through the injection pipe orifice.

At the same time, when the outer side of the eccentric disk contacts the pressure relief valve, the pressure relief valve will relieve the excess pressure in the enhanced liquid injection mixing tank, and the raw materials can be pushed into the diversion joint by the eccentric disk, making the density of the raw materials higher when being discharged;

[0014] 2. When the raw materials are transported into the spray pipe through the diversion joint and discharged through the conveying head in the present utility model, the injection nozzle gathers the raw materials to ensure the conveying density of the raw materials. When the inner lining cylinder is transported into the spray pipe by the raw materials, the inner lining cylinder rotates and displaces downward under pressure and compresses the spring at the same time, which is convenient for remixing the raw materials.
