Description

Oil storage tank bottom surface cleaning equipment and oil storage tank including it
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 include the bottom surface cleaning equipment oil storage tank.
Background technique
During oil extraction, 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, it, when crude oil stores in oil storage tank, can be accumulated in because sinking naturally than great Tank bottom, forms black but also thick colloid substance layer not only, as sludge from oil tank, bottom greasy filth with the continuous storage and transportation time growth And increase, seriously affect the storage and transportation production of oil tank, it is necessary to periodically be purged.
In general, being equipped with the strong mud exhauster of QPN inside oil storage tank, carry out auxiliary sludge discharging, is inhaled tank bottom bed mud by negative pressure Out, it but removes and is not thorough.
In addition, many oil plants still rest on the real production phase of artificial clear mud cleaning of evaporator, personnel is needed to enter operation in tank, According to " vertical cylinder steel welds petroleum tank and repairs regulation " regulation, the rehabilitating of tank phase is 5-7 years, manually cleans 1 oil Tank at least takes 45 days, and advanced COW butterworth also needs 7 people's continuous work 15 days in the world, a large amount of flammable because existing in tank With other pernicious gases, operating environment is severe, and risk is very high, large labor intensity, and clear tank is long in time limit, causes environmental pollution also very Greatly.
The cleaning method of oil tank in the world includes mechanical cleaning, chemical cleaning, waterpower cleaning, steam clean etc. at present, greatly Most cleaning methods cleans after needing to empty in oil tank.However, the Petroleum Production and strategic reserves task in current China Heavy, petroleum tank appearance is at full stretch, is difficult to vacate oil tank progress clear tank prolonged in this way.With the increase of oil reserve, use A large amount of oil storage tank, there is 20,000,000 m every year3Above crude oil storage tank 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, low efficiency, and in conjunction with actual conditions, the shortening that many scholars propose adaptation China's actual conditions is clear The idea in period is washed, cleaning in 3-6 months or so is primary, and because the cleaning frequency is short, sludge from oil tank is few, and cleaning speed is fast.But it is this to think Method can not still solve cleaning equipment reality far from enough.
Summary of the invention
Oilcan cleaning equipment simple, at low cost that the object of the present invention is to provide a kind of structures, and used 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 invention adopts the following technical scheme:
A kind of oil storage tank bottom surface cleaning equipment, comprising: first motor, speed reducer, blade wheel, swivel mount, linkage, Two motors and cleaning plant, the first motor is connected to speed reducer, and drives the blade wheel to rotate by speed reducer, described Second motor is connected to the speed reducer, and drives the swivel mount rotation by the speed reducer, and the cleaning plant passes through Linkage is connected to the swivel mount, and the cleaning plant includes rack, running gear, conveyer belt and multiple scraper plates, described Rack connects the linkage, and the running gear includes motor and speed reducer, and the conveyer belt covers on transmission shaft, described Transmission is pivotally connected to the running gear, and the scraper plate is fixed on the conveyer belt.
Preferably, the cleaning plant further include dial mud device, described group of mud device include driving lever and be located at driving lever two 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 rack, the driving lever is moved forward and backward relative to the transmission belt.
Preferably, the linkage is telescopic rod.
Further, the cleaning plant further includes revolving support, and the revolving support is arranged in the top of rack, and even It is connected to the linkage.
Further, sealing ring is provided 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, the oil storage tank includes that above-mentioned bottom surface is clear Clean equipment.
It oil storage tank bottom surface cleaning equipment of the invention and is had the advantages that including its oil storage tank
1. oil storage tank, in addition to having normal oil storage function, oil storage tank itself can clean bottom surface, bed mud can be converged simultaneously The bed mud that interior bottom portion is accumulated excludes, and oil sludge in oil storage tank outlet has greasy filth suction means that greasy filth is sucked out;
2. bottom surface cleaning equipment structure of the invention is simple, at low cost, can by largely making and applying in oil storage tank, The bottom surface of oil storage tank can periodically be cleaned during oil storage tank use, scale removal process does not need manual intervention;
3. this included cleaning function can increase oil storage tank storage usually, while can be greatly lowered 5 years once Scavenging period, because tank interior bed mud amount is few, improve cleaning efficiency in the cleaning in 5 years periods, be staff It brings convenience;
4. the power mechanisms such as motor reducer required for cleaning equipment are etch-proof, and have sealing, so Without worrying greasy filth intrusion, the problem of corrosion, in addition, power source uses synchronous generator, so the course of work relatively safety is not High temperature and open fire can be generated;
5, the greasy filth of oil tank bottom center is discharged to outside blade wheel by oil tank center in bottom surface using " oil extraction mud blade wheel " Other than circle, can solve oil storage tank center cleaning less than the problem of.
6, the cleaning equipment of bottom surface cleaning plant is connected by pivoting support with telescopic rod, and cleaning equipment can become when working Change angle, easy cleaning;
7, the problem of bottom surface cleaning device uses crawler unit, can't walk any longer when without worrying that greasy filth is arranged at bottom.
