A control method of a mobile tank feeding system without dead angle return cleaning

Abstract

The invention relates to a control method for dead-corner-free return material cleaning of a moving tank charging system. The system comprises a first moving tank, a second moving tank, a charging barrel, a charging barrel pipeline system and a cleaning device. The discharging port of the first moving tank and the discharging port of the second moving tank are respectively provided with a manual discharging ball valve, the exit ends of the two manual discharging ball valves are respectively provided with a discharging quick coupling, each discharging quick coupling is connected with a charging hose, the two charging hoses are both connected to a discharging two-position three-way solenoid valve, the exit end of the discharging two-position three-way solenoid valve is connected with a feeding solenoid valve, the feeding solenoid valve is connected to the charging barrel and the charging barrel pipeline system through feeding pipelines, and the cleaning device comprises a cleaning water pipeline and a compressed air pipeline. The method comprises the following steps of (1) enabling moving tanks to be connected, (2) entering a pre-filling and pre-production process, (3) feeding back materials, (4) removing the moving tanks and (5) cleaning the pipelines. The control method for the dead-corner-free return material cleaning of the moving tank charging system solves feed liquid residue problems, completely eradicates hidden dangers of mixed materials, and improves charging quality of cut tobaccos.

Description

technical field [0001] The invention relates to the field of feeding for shredded cigarettes, in particular to a control method for a moving tank feeding system without dead ends for returning and cleaning. Background technique [0002] In order to improve the core competitiveness of "Chinese-style cigarettes" and produce high-quality cigarette products, tobacco companies have higher and higher requirements for product quality. Feeding is an important link in the silk making process. By spraying the feed liquid on the tobacco sheets accurately and evenly, the physical properties and sensory quality of the tobacco sheets after feeding are significantly improved. [0003] At present, most of the domestic and foreign silk feeding uses long-distance pipelines to transport the material liquid from the sugar kitchen to the on-site feeding point. There are residues and losses of the material liquid in the long-distance pipeline, long time for the material liquid to be blown back an...

AI Technical Summary

Problems solved by technology

[0004] Whether it is the traditional pipeline long-distance conveying feeding system or the mobile tank feeding system, due to natural defects in pipeline design and other reasons, there are still some problems in material liquid recovery and pipeline cleaning: due to the dead angle in the pipeline, the conveying material The pipeline between the discharge three-way valve of the liquid and the manual discharge ball valve of the mobile tank, the pipeline between the return valve and the manual feed ball valve of the mobile tank cannot be cleaned, and the return is not thorough enough, resulting in the presence of liquid to a certain extent. Problems such as residue, incomplete cleaning, and mixing of materials and liquids

Therefore, no dead angle return and pipeline cleaning have always been the ultimate goal pursued by the tobacco industry in the feeding system, but there is still no good solution
