Emergency rapid cooling rod and manufacturing method thereof

Abstract

The invention discloses an emergency rapid cooling rod and a manufacturing method thereof, the structure comprises a long-strip cylindrical rod body, the interior of the rod body is hollow and is filled with a heat-conducting medium, the surface of the inner wall of the rod body is rough, the rod body comprises an end socket and a column pipe, and the manufacturing method comprises the step of pouring, a tungsten column pipe with dense sand holes in the inner wall and the opening end is poured out, then the column pipe is filled with a heat-conducting medium, a seal head is welded to the opening of the column pipe in a fusion mode in a friction welding mode, a finished rod body is obtained, and when chemical liquid and molten metal liquid leak out, a plurality of control circulating water paths can be used for driving a plurality of rod bodies to vertically descend, so that the rod bodies are prevented from falling off. The rod body is inserted into a leaked object, high temperature of the leaked object is transmitted to the bottom of the rod body, the rod body is matched with an internal heat-conducting medium to perform up-and-down heat exchange, the interior of the leaked object is cooled, and meanwhile, the effect of synchronously and rapidly cooling the leaked object inside and outside is achieved in cooperation with cooling operation of external fire extinguishing equipment.

Description

technical field [0001] The invention relates to the field of emergency equipment, in particular to an emergency rapid cooling rod and a manufacturing method thereof. Background technique [0002] In the process of metal material production and chemical production, if a power outage causes the crucible mounted on the crane to fall, or the working crucible, boiler, reaction tank is aged and damaged, or a high-pressure explosion occurs, the chemical liquid and molten metal will leak. Out, such as oil refining, iron slurry leakage, at this time it needs to be cooled urgently; [0003] In the prior art, fire extinguishing equipment and high-pressure water guns are often used for fire extinguishing and cooling (and most chemical liquids cannot be in contact with water to extinguish the fire). Maintaining a high temperature makes the fire extinguishing speed of the fire extinguisher unsatisfactory; [0004] In the process of metal material production and chemical production, such...

Problems solved by technology

[0003] In the prior art, fire extinguishing equipment and high-pressure water guns are often used for fire extinguishing and cooling (and most chemical liquids cannot be in contact with water to extinguish the fire). Maintaining a high temperature makes the fire extinguishing speed of the fire extinguisher unsatisfactory;

[0004] In the process of metal material production and chemical production, such as using chemical materials and metal materials to make larger products with low surface roughness, for example, using polymethyl methacrylate to customize and prepare 1m*1m*0.5m cubes , due to the large volume, after pouring, the internal and external cooling is uneven, which will cause the middle part of the block to collapse, resulting in the shape and size of the block not meeting the requirements
