Description

Technical Field

[0001] The utility model belongs to the field of cleaning and filling of liquefied natural gas cylinders, and in particular relates to a hanging method lateral worm-driven opposite brush cylinder cleaning device. Background Art

[0002] Liquefied natural gas has high calorific value, no residue after combustion, clean and environmentally friendly. Compared with coal, oil and other energy sources, it has the advantages of being cheap, taking up less space, safe and clean to use. Therefore, using natural gas for cooking is the first choice for thousands of households. Liquefied natural gas cylinders are also a must-have for thousands of households. Commonly used household liquefied natural gas cylinders are 15 kg cylinders, which weigh 31.5 kg after filling. The cylinders in the application document of this utility model refer specifically to household liquefied natural gas cylinders. Household liquefied natural gas is a consumable, and the cylinders need to be refilled after use; household natural gas cylinders are also flammable and explosive items. Before filling, they need to be externally cleaned, the appearance of the cylinder body checked, and the switch leak checked. Only qualified cylinders can be filled. It is worth mentioning that most of the current cylinder cleaning and filling are still performed by manual operation, which requires manual cleaning of the bottle body, inspection of the bottle body, opening the switch, filling with natural gas, weighing, closing the switch again, checking the seal, and carrying. Manually carrying a huge number of 31.5 kg cylinders is obviously arduous, time-consuming, labor-intensive and inefficient. Due to the heavy workload and lack of responsibility, the risk of major accidents such as gas leakage, deflagration and explosion may occur. In view of the above problems, the inventors have developed a hanging steel cylinder cleaning and inspection device. Utility Model Content
