Oil storage tank side wall cleaning equipment and oil storage tank including same

Abstract

The invention provides oil storage tank side wall cleaning equipment which comprises a base plate (1), a cleaning equipment body (2) and guide wheels (3). The base plate comprises a traveling device (11) and a bottom plate (12). The two sides of the bottom plate are fixed to the traveling device. The traveling device is driven by a motor to move on the bottom face of an oil storage tank. The cleaning equipment body (2) comprises a frame (21), a rolling shaft (22), the motor (23) and scrapers (24). The frame is fixed to the bottom plate. The two ends of the rolling shaft are installed on the frame. The motor is connected with one end of the rolling shaft and drives the rolling shaft to rotate relative to the frame. The scrapers are fixed to the rolling shaft and face the side wall of the oil storage tank. The guide wheels are fixed to the top of the frame and installed on a guide rail frame at the top of the oil storage tank. The guide wheels can move relative to the guide rail frame, and accordingly, the side wall cleaning equipment can move along the inner wall of the oil storage tank. The oil storage tank side wall cleaning equipment provided by the invention can clean the oil storage tank regularly without human intervention.

Description

technical field [0001] The present invention relates to the technical field of oil storage tank cleaning equipment, in particular to an oil storage tank side wall cleaning equipment, and also relates to an oil storage tank including the side wall cleaning equipment. 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 clear. [0003] Usually, a QPN strong...

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
