Description
The present invention relates to a kind of pneumatic process equipment.It is applicable to that it is the preliminary treatment of purpose that chain class workpiece and spuious workpiece in batch carry out with paint removal rust cleaning lay the grain when surface treatment.Be applied in the Surface Engineering field.
Can be used for chain class and spuious in batch workpiece carries out the prior art that paint removal rust cleaning lay the grain handles and pickling, sandblast, vibration sand launder lay the grain, cylinder is arranged from methods such as bumps.But in application, always there are some problems not solve.
Pickling is a most widely used technology in producing in enormous quantities, belongs to chemical method, also is the maximum a kind of prior art of problem.One of problem of pickling is that environmental pollution is outstanding, and pickle pollutes and have stubbornness, and influence surface is big, and the characteristics of refractory reason are the main sources of industrial water pollution.Two of the problem of pickling is that pickle acts on meeting initiation microfissure on the metal, forms mechanism of hydrogen embrittlement, reduces mechanical strength.So, do not allow the anchor chain acid pickling and rust removing in the Ship's Repair industry.Though but the problem of pickling three is pickling according to the pickling tube size a large amount of workpiece of batch processing once, the chemical process of acid pickling and rust removing is slower.Four of the problem of pickling is that acid solution has danger to environment to surrounding devices to the people, material cost and management cost costliness in transportation stores a series of flow processs such as blending additional discharging.Five of the problem of pickling is that pickling can not enter next procedure afterwards at once, still must not only expend a large amount of clear water, also cause surface treatment procedure to be interrupted through cleaning and drying process, and high to cleaning with dry technological requirement, otherwise remaining acid can have a strong impact on the final mass of workpiece.
Sandblast is the surface preparation technology that widespread popularity is only second to pickling.Sandblast belongs to pure physical method.Technical process is simple more than pickling.But there are disadvantages such as dust pollution is big, labor strength is big in common open blasting method.Special-purpose penetration type sand-blasting machine only is fit to rigidity elongated workpiece such as pipe profile etc., but still difficult for the processing of anchor chain class workpiece or spuious workpiece etc.In addition, the sandblast process must manually participate in, and is difficult to form automatic production.
Vibration lay the grain method relies on mechanical oscillation to force sand grains (friction) shuttling movement and original place vibration in groove in the sand launder, workpiece to be subjected in the middle of sand grains that sand grains moves and the rubbing action vibrated and obtain grinding.One of vibration lay the grain method problem is owing to there being mechanical oscillation, so noise is very big, and the requirement of mechanical strength height of equipment; Two of problem is that vibrational energy is limited, and process time is longer; Three of problem is to add the dust that forms man-hour to be difficult to get rid of, and the variation of sand material quality can influence the processing quality; Four of problem is that shake table is difficult to do greatly, and the sand launder size is restricted, so can not process more heavier workpiece, the production efficiency of vibration lay the grain method is not high.
Cylinder is considered to the advanced method that Ship's Repair already is used for the anchor chain rust cleaning from the bump method.It is that whole of heavy anchor chain is dropped in the rolling casing, rotates with the heavy-duty motor head roll, relies on self-collision friction to remove the oxide skin of the workpiece such as anchor chain in the cylinder.Sometimes in cylinder, add a certain amount of sand material to improve grinding effect.Problem is that this method energy consumption is big, and the eccentric rotary body that drives several tons even tens of tons needs the energy of consume significant; Environmental noise is big, and dust pollution is big.In addition, surface treatment is inhomogeneous also is the problem that is difficult to overcome.
The objective of the invention is to invent a kind of effective, can rationally evade the removing surface method of the disadvantage in the said method at anchor chain or spuious workpiece.Method of the present invention and device thereof can reduce energy consumption, reduce noise, suppress dust, and can realize handling automatically.Finally reach the purpose that improves surface treatment quality and efficient.
The object of the present invention is achieved like this: the present invention includes have a fluidizer put sand launder (pond), compressed air gas source and compressed air control treating apparatus and dust arrester.
The sand washing groove keeps the rigid container of inactive state when being a job.Its inside is equipped with fluidizer.Fluidizer is pressure-air to be injected sand material inside make the sand material present the device of fluidisation and fluidized state, it has air nozzle device and two kinds of forms of fluidized bed plant, and wherein fluid bed is can hold that the sand material is unlikely to fall and can be by the special division board of air-flow.Air enters in the sand material through fluidizer and drives the fluidized state that the sand material presents similar liquids under the effect of air pressure.The sand material of fluidized state has very strong extruding and frictional property, and workpiece places in the middle of this sand materials flow body that presents fluidized state that surface of the work is ground fully after a period of time, thereby reaches the purpose of removing surface impurity.
Compressed air gas source is the energy source of sand material to the workpiece acting, and compressed air control treating apparatus is the device of control stream pressure flow, also is simultaneously the device that keeps flow quality.
Dust arrester is the device that contains the dust absorption of air and dust separation is come out that sand material and workpiece with fluidized state in the sand washing groove produce, and it can avoid flour dust overflow to pollute effectively.
The advantage of sand washing method of the present invention and device thereof has:
1. in the present invention,, avoided driving the huge energy consumption of material containing cell body motion, avoided equipment high strength structure manufacturing cost simultaneously because the sand washing groove remains static.The technological transformation that existing static descaling bath (pond) changes to the sand washing groove also is convenient in the present invention.
2. in the present invention, after workpiece is gone into groove, only need to open compressed air and dust pelletizing system, wait to configure pressure flow after machine just can turn round voluntarily, need not manual intervention.It is very light to work.
3. sand material acting process noiselessness, friction in the present invention.
4. in the present invention, workpiece is immersed in the middle of the fluidized state sand materials flow body of similar liquids, and any position can be ground fully, and mass ratio is average.
5. in the present invention, constantly the impurity band that comes off from workpiece that the air-flow that rises dust that particle is less and proportion the are lighter material that shakes out is collected by dust arrester then.So the sand material can keep quality preferably, thus the operating efficiency of held stationary and processing quality.
