Cleaning device for oil storage tank

Abstract

The invention provides a cleaning device for an oil storage tank. The cleaning device comprises an oil storage tank body, compression devices, a connection plate, connection devices, a threaded rod, arotary motor, a water storage tank and a cleaning assembly. The two first compression devices are symmetrically arranged at the top end of the side wall of the oil storage tank body. The connection plate is fixedly connected between the two first compression devices. The upper portion of the connection plate is slidably connected with the threaded rod through the connection devices. One end of the threaded rod is connected with the one first compression device. The other end of the threaded rod penetrates through the other first compression device and is connected with the output end of the rotary motor. The lower portion of the connection plate is connected with the water storage tank. A plurality of cleaning device bodies are arranged around the outer wall of the water storage tank andabut against the inner wall of the oil storage tank body. The rotary motor can drive the connection plate and the water storage tank to slide up and down, so that the cleaning device bodies move up and down to clean the inner wall of the oil storage tank body. Through the provided cleaning device for the oil storage tank, labor intensity can be relieved, cleaning cost is lowered, and cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oil storage tanks, in particular to a cleaning device for oil storage tanks. Background technique [0002] The finished or semi-finished oil products in the petrochemical industry need to be stored in oil storage tanks, and the finished or semi-finished oil products contain various impurities that are inevitable, so after the oil storage tanks are used for a period of time, the impurities in the crude oil will be deposited in Most of the tank bottom and tank wall are deposited on the bottom of the tank, which reduces the effective capacity of the oil storage tank and affects the efficiency of the oil storage tank. Therefore, the oil storage tank needs to be inspected and maintained regularly and the sludge in the tank should be removed. [0003] At present, the traditional domestic oil tank cleaning method mainly uses manual cleaning. The staff wear positive pressure respirators, protective clothing and o...

Problems solved by technology

[0004] Manual tank cleaning has problems such as high labor intensity, long construction period, poor safety, low crude oil recovery rate, and environmental pollution; at present, with the large-scale construction of large-scale oil storage tanks in China and the increasing emphasis on environmental protection issues, manual tank cleaning has become Does not meet the objective requirements of the environment and development, it is inevitable to eliminate manual tank cleaning and improve oil storage tanks
