Steeper liquid level probe spraying and blowing device

Abstract

The invention discloses a steeper liquid level probe spraying and blowing device. The steeper liquid level probe spraying and blowing device comprises an air inlet pipe, temperature detectors and an electromagnetic stop valve, wherein three air outlet pipes are arranged on the air outlet end side of the air inlet pipe, and the three air outlet pipes are correspondingly installed in a low liquid level hole, a middle liquid level hole and a high liquid level hole of a steeper respectively; the temperature detectors are respectively arranged in the air outlet pipes in the three liquid level holes; the electromagnetic stop valve is arranged on the air inlet pipe and used for opening or closing a compressed air channel of the air inlet pipe. The device is advantaged in that impurities attached to a liquid level hole and a temperature probe of the impregnator can be effectively cleaned and blown, and smooth production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of macerators, in particular to a spraying device for a liquid level probe of a macerator. Background technique [0002] In the 1140kg / h carbon dioxide expanded shredded tobacco production line, the macerator is the main process equipment for shredded tobacco expansion. It mainly soaks shredded tobacco with a certain pressure of carbon dioxide liquid in the macerator, so that the carbon dioxide liquid can fully immerse the inside of the shredded tobacco cell tissue, and then through the exhaust Liquid, decompression and other means, so that the carbon dioxide liquid inside the tobacco cell tissue into dry ice (solid), that is, to form dry ice tobacco. [0003] In order to control the amount of carbon dioxide filled liquid in the process of filling the impregnator, three liquid level holes, low, medium and high, are set in the impregnator. The control method is to install temperature probes in the low, medium...

AI Technical Summary

Problems solved by technology

[0004] In the process of immersing shredded tobacco, impurities such as tobacco dust and dust in the shredded tobacco will float on the surface of the carbon dioxide liquid. Since the liquid level of carbon dioxide is basically level with the middle liquid level hole, it will cause part of the tobacco dust and dust to float on the liquid level probe. At the hole, when the steeping process of shredded tobacco is completed, the carbon dioxide liquid is recovered and the carbon dioxide gas is discharged, the lower bottom cover of the macerator is opened, and the sharp changes in temperature and pressure may form part of the tobacco powder, smoke dust and carbon dioxide frozen in the hole of the liquid level probe. inside, causing the temperature probe or liquid level hole to be blocked

During the production of the next pot, the temperature probe will not be able to contact the carbon dioxide liquid, and the inaccurate temperature measurement will cause the liquid level to be judged incorrectly, resulting in the "V23 filling weight and liquid level switch comparison alarm" to stop the equipment and cause production to be cut off

At the same time, it is necessary to manually remove the temperature probe to manually spray the liquid level hole, which seriously affects the production efficiency, and there is also a risk of production breakage
