Abstract

A carbon dioxide automatic filling system for fire protection of a rolling mill comprises a weighing device, a gas filling device and a control device. The weighing device comprises an S-shaped tensile weighing test block, the upper end of the S-shaped tensile weighing test block is hung on a cross beam through a first double-end stud, the lower end of the S-shaped tensile weighing test block is connected with a hanging mechanism through a second double-end stud, and the hanging mechanism is used for hanging a carbon dioxide storage bottle. The gas filling device comprises a gas filling pipeline and a gas filling hose for connecting the gas filling pipeline with the carbon dioxide storage bottle, and an electromagnetic valve is arranged on the gas filling hose. The control device is connected with the S-shaped tensile weighing test block and the electromagnetic valve. The carbon dioxide automatic filling system has the following beneficial effects that 1, the carbon dioxide automatic filling system is convenient to adjust, small in occupied space and convenient to maintain; 2, the carbon dioxide automatic filling system is beneficial to improving the accuracy of weighing measurement; 3, the carbon dioxide storage bottle is convenient to disassemble and assemble; 4, the influence of shaking on the S-shaped tensile weighing test block is eliminated, so that the weighing is more stable and reliable; and 5, automatic gas filling to the carbon dioxide storage bottle is realized.

Description

technical field [0001] The invention relates to the field of non-ferrous metal rolling, in particular to a carbon dioxide automatic inflation system for rolling mill fire protection. Background technique [0002] In the rolling process of non-ferrous metal strips and foils, it is necessary to use process lubricants for lubrication to achieve the effects of cleaning the surface, cooling the plate, and controlling the surface waves of the strip. Lubricants are usually based on kerosene with small amounts of additives. During the rolling process, the volatilization of the lubricant will produce a large amount of oil mist. The oil mist with a large concentration will easily catch fire in the case of mechanical overheating, static electricity accumulation, broken belt collision or high temperature. Therefore, the working system of the rolling mill must be equipped with Sufficient extinguishing agent. [0003] In the field of non-ferrous metal processing, carbon dioxide gas is o...
