Crude oil sedimentary oil sand resistance-reducing rotary flushing and floating device

Abstract

The invention discloses a crude oil sedimentary oil sand resistance-reducing rotary flushing and floating device, and relates to the technical field of oil tank cleaning. The device comprises an outershell, a power device and a rotating body, the outer shell comprises a conical shell, a flow guide sleeve is fixed to the large-opening end of the conical shell, a cylindrical shell is transversely fixed in the conical shell in a penetrating mode, and an arc-shaped shell is fixedly communicated between the position, located outside the conical shell, of the cylindrical shell and the outer side ofthe conical shell. Fluid can be guided into the rotating body through the outer shell, when the fluid penetrates through the outer shell, the fluid can drive a turbine body to rotate, so that a turbine shaft, a first-stage worm, a first-stage worm wheel, a second-stage worm wheel, a second-stage worm and a gear shaft are driven to rotate, and the rotating body can be driven to rotate through cooperation of a gear and a gear sleeve; and the fluid in the rotating body is ejected at a high speed in a rotating mode, the tank bottom can be comprehensively swept and cleaned, and the problem that oil sand in an existing storage tank needs to be manually swept after being deposited is solved.

Description

technical field [0001] The invention belongs to the technical field of oil tank cleaning, in particular to a rotary flushing device for reducing resistance of crude oil deposits and oil sands. Background technique [0002] In major oil fields, large tank sedimentation and sand removal devices are more widely used, but when a large amount of solid particles such as mud and sand carried by the oil-water mixture settle to the bottom of the tank by gravity, and deposit to a certain extent, it will seriously affect the settlement tank. At the same time, there are problems such as the relative reduction of the tank capacity, so the sand must be cleaned in time. [0003] In order to solve this problem, in the past, the tanks could only be stopped regularly and cleaned manually. When cleaning sand in the settling tank, the method of manual high-pressure water washing after pouring the tank was used to clean the tank. This method of sand removal has the following disadvantages: [0...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide a crude oil deposit oil sand drag reduction rotary floater, through which the fluid can be guided into the rotating body through the outer casing, and when the fluid passes through the outer casing, the fluid can drive the turbine body to rotate, thereby driving the turbine shaft, The first-stage worm, the first-stage worm gear, the second-stage worm wheel, the second-stage worm, and the gear shaft rotate. Through the cooperation of the gear and the gear sleeve, the rotating body can be driven to rotate. The high-speed injection of the fluid in the rotating body can completely clean the bottom of the tank. Sweeping and cleaning can improve the effect of sand discharge and sand washing of the tank, and solve the problem of manual cleaning after the oil sand deposits in the existing storage tanks
