Description
Technical field
The present invention relates to oil-storage tank cleaning equipment technical field, in particular to a kind of oil storage tank bottom surface cleaning equipment,
Further relate to the oil storage tank for including the bottom surface cleaning equipment.
Background technology
During oil extraction, the molecule in oil reservoirs, a small amount of mechanical admixture, the grains of sand, soil, heavy metallic salt with
And the weight oily matter such as paraffin and pitch, when crude oil is stored in oil storage tank, it can be accumulated in because sinking naturally than great
Tank bottom, black but also thick colloid substance layer, as sludge from oil tank are formed not only, bottom greasy filth is with the growth of continuous accumulating time
And increase, have a strong impact on the accumulating production of oil tank, it is necessary to be periodically purged.
Generally, the strong mud exhausters of QPN are installed inside oil storage tank, carry out auxiliary sludge discharging, are inhaled tank bottom bed mud by negative pressure
Go out, but remove not thorough.
In addition, many oil plants still rest on the real production phase of artificial clear mud cleaning of evaporator, personnel are needed to enter operation in tank,
According to《Vertical cylinder steel welding petroleum tank repairs code》Regulation, rehabilitating of tank phase are 5-7 years, manually clean 1 oil
Tank at least takes 45 days, and advanced COW butterworths also need 7 people continuously work 15 days in the world, a large amount of flammable because existing in tank
With other pernicious gases, operating environment is severe, and dangerous very high, labor intensity is big, and clear tank is long in time limit, causes environmental pollution also very
Greatly.
The cleaning method of oil tank includes mechanical cleaning, Chemical cleaning, waterpower cleaning, steam clean etc. in the world at present, greatly
Most cleaning methods need to be cleaned after oil tank is emptied.However, the Petroleum Production and strategic reserves task in current China
Heavy, petroleum tank appearance is at full stretch, it is difficult to which vacateing oil tank carries out so prolonged clear tank.With the increase of oil reserve, use
Substantial amounts of oil storage tank, there is 20,000,000 m every year3Crude oil storage tank above needs to clean, with the increase of deposit, this numerical value
Also constantly soaring.China's present case, because advanced cleaning equipment involves great expense, it is impossible to which equal proportion is equipped with, simultaneously
The artificial cleaning frequency is long, risk is big, efficiency is low, and with reference to actual conditions, the shortening that many scholars propose adaptation China's actual conditions is clear
The idea in cycle is washed, once, because the cleaning frequency is short, sludge from oil tank is few, and cleaning speed is fast for cleaning in 3-6 months or so.It is but this to think
Method can not still solve cleaning equipment reality far from enough.
The content of the invention
Used it is an object of the invention to provide a kind of Oilcan cleaning equipment simple in construction, cost is low, and in oil storage tank
Period can carry out periodic cleaning to the inside of oil storage tank, to overcome problem of the prior art mentioned above.
To achieve the above object, the present invention uses following technical scheme：
A kind of oil storage tank bottom surface cleaning equipment, including：First motor, reductor, blade wheel, swivel mount, linkage, the second electricity
Machine and cleaning plant, first motor connection drive the blade wheel to rotate to reductor, and by reductor, and described second
Motor connection drives the swivel mount to rotate to the reductor, and by the reductor, and the cleaning plant passes through connecting rod
Device is connected to the swivel mount, and the cleaning plant includes frame, running gear, conveyer belt and multiple scraper plates, the frame
The linkage is connected, the running gear includes motor and reductor, and the conveyer belt is enclosed on power transmission shaft, the transmission
The running gear is pivotally connected to, the scraper plate is fixed on the conveyer belt.
Preferably, the cleaning plant also includes dialling mud device, and described group of mud device includes driving lever and positioned at driving lever both sides
Spring, the driving lever is located at the front of conveyer belt, and the spring one end is fixed on the driving lever, and the other end is fixed on described
In frame so that the driving lever can move forward and backward relative to the transmission belt.
Preferably, the linkage is expansion link.
Further, the cleaning plant also includes revolving support, and the revolving support is arranged in the top of frame, and even
It is connected to the linkage.
Further, it is provided with sealing ring in the revolving support.
Preferably, the scraper plate is alternately fixed on the transmission belt.
It is further preferable that the running gear is cterpillar drive.
According to another aspect of the present invention, the present invention also provides a kind of oil storage tank, and it is clear that the oil storage tank includes above-mentioned bottom surface
Clean equipment.
The present invention oil storage tank bottom surface cleaning equipment and had the advantages that including its oil storage tank：
1. oil storage tank, in addition to possessing normal oil storage function, oil storage tank itself can clean bottom surface, bed mud can be converged and incite somebody to action in
The bed mud that portion bottom is accumulated excludes, and oil sludge in oil storage tank outlet has greasy filth suction means to suction out greasy filth；
2. the bottom surface cleaning equipment of the present invention is simple in construction, cost is low, can be by largely making and applying in oil storage tank, can be with
The bottom surface of oil storage tank is periodically cleaned during use in oil storage tank, scale removal process does not need manual intervention；
3. this cleaning function carried can increase oil storage tank storage usually, while 5 years once clear can be greatly lowered
The time is washed, in the cleaning in 5 years cycles, because tank interior bed mud amount is few, cleaning efficiency is improved, is brought for staff
It is convenient；
4. the actuating units such as the motor reducer required for cleaning equipment are etch-proof, and have sealing, so not having to
Greasy filth intrusion is worried, the problem of corrosion, in addition, power source uses synchronous generator, so the course of work will not produce more safely
Raw high temperature and naked light；
5th, bottom surface oil tank center use " oil extraction mud blade wheel " by the greasy filth of oil tank bottom center be discharged to blade wheel it is cylindrical with
Outside, can solve the problems, such as oil storage tank center cleaning less than.
6th, the cleaning equipment of bottom surface cleaning plant is connected by pivoting support with expansion link, and cleaning equipment can become when working
Change angle, easy cleaning；
7th, bottom surface cleaning device uses crawler unit, the problem of can't walk any longer when having greasy filth without worry bottom.
