Description

Technical Field

[0001] This utility model relates to the field of hollow equipment cleaning technology, and in particular to an automatic cleaning device for horizontal storage tanks. Background Technology

[0002] Oil is typically stored in tanks, which are mainly classified by shape into: vertical domed tanks, circular horizontal tanks, and elliptical horizontal tanks; by operating condition into: operational tanks, long-term storage tanks, and transfer tanks; and by type of oil stored into: aviation kerosene tanks, diesel tanks, heavy oil tanks, and gasoline tanks. After a period of use, impurities in the oil will accumulate on the inner sidewalls and end walls of the tank. When changing the stored oil according to relevant requirements, the inner sidewalls and end walls will also retain the previously stored oil. All of these factors contribute to increased impurities and reduced quality of the stored oil, affecting both the quality of the oil and its safe operation. According to relevant storage regulations, tanks must be cleaned regularly every 0.5 to 5 years, depending on the operating conditions and the type of oil stored.

[0003] Existing technologies often employ manual cleaning of storage tanks to address the aforementioned tank cleaning issues. However, considering that the tank volume is mostly around 100 cubic meters... 3 Even 1000M 3 Furthermore, the manhole at the top of the storage tank is only 60cm in size. Manual cleaning requires multiple operators to enter the tank, and scaffolding must be erected layer by layer inside so that cleaning personnel can stand on it to clean the interior. This requires repeated scaffolding erection for horizontal tanks of different sizes and shapes. Manual tank cleaning suffers from drawbacks such as high labor intensity, poor safety, long construction period, mediocre cleaning results, and the risk of operator poisoning due to the inhalation of harmful gases. It increases storage, cleaning, and safety costs, hinders expanded production and improved tank utilization efficiency, and fails to meet the needs of social production.

[0004] Therefore, there is an urgent need in the existing technology for a cleaning device that is easy to operate, highly automated, safe, lightweight, widely applicable, and low in operating cost. Utility Model Content
