Equipment for cleaning bottom of oil storage tank and oil storage tank including same

Abstract

The invention provides oil storage tank bottom surface cleaning equipment. The equipment comprises a first motor (1), a speed reducer (2), a blade wheel (3), a rotating frame (4), a connecting rod device (5), a second motor (6) and a cleaning device (7), wherein the first motor is connected to the speed reducer and drives the blade wheel to rotate through the speed reducer; the second motor is connected to the speed reducer and drives the rotating frame to rotate through the speed reducer; the cleaning device is connected to the rotating frame through the connecting rod device; the cleaning device comprises a rack (72), a walking device (71), a conveyor belt (73) and a plurality of scrapers (74); the rack is connected with the connecting rod device; the walking device comprises a motor and a speed reducer; the conveyor belt is arranged on transmission shafts in a sleeving mode; the transmission shafts are connected to the walking device; and the scrapers are fixed on the conveyor belt. The oil storage tank bottom surface cleaning equipment can be used for regularly cleaning an oil storage tank without human intervention.

Description

technical field [0001] The present invention relates to the technical field of cleaning equipment for oil storage tanks, in particular to cleaning equipment for the bottom surface of an oil storage tank, and also relates to an oil storage tank including the cleaning equipment for the bottom surface. Background technique [0002] In the process of crude oil extraction, tiny particles in the oil reservoir, a small amount of mechanical impurities, sand, soil, heavy metal salts, and heavy oily substances such as paraffin and asphalt will naturally sink due to their high specific gravity. When crude oil is stored in the oil storage tank When it accumulates at the bottom of the oil tank, it forms a black and thick gelatinous substance layer, which is the bottom sludge of the oil tank. The sludge at the bottom increases with the continuous storage and transportation time, which seriously affects the storage and transportation production of the oil tank. It must be regularly to clea...

Problems solved by technology

In my country's current situation, because advanced cleaning equipment is expensive, it is impossible to equip it in equal proportions. At the same time, the manual cleaning cycle is long, the risk is high, and the efficiency is low. Combined with the actual situation, many scholars have proposed the idea of ​​shortening the cleaning cycle to adapt to China's national conditions. 3 -Cleaning once every 6 months or so, due to the short cleaning cycle, less oil tank bottom mud and fast cleaning speed

But this idea still cannot solve the reality that cleaning equipment is far from enough
