Description
Technical field
The present invention relates to field of machining and machinebuilding technology, further relate to the grease removal device, particularly a kind of hot cigarette negative pressure degreaser, can remove the grease of porous belts oil components interior.
Background technology
In the industrial products manufacture process, in order to meet processing technology needs or the needs based on the protection process equipment, in part mechanical part process, usually adopt lubricating oil as the lubricant medium in the component processing process or cooling medium.For meeting the requirement of product cleannes, after component processing completes, need parts surface and inner grease are thoroughly removed, otherwise residual grease not only easily adhesion dust and other foreign material, and can affect next step processing or assembling procedure.The thorough removal of porous type mechanical part internal grease be all the time the puzzlement product efficiently, the difficult problem that thoroughly cleans.
The methods that great majority are removed greases adopt the modes of Chemical cleaning, after having plenty of and being processed with a certain proportion of strong alkali solution, then use a large amount of clear water rinsings clean, the effect of deoiling is better, but water consumption is too large, the sewage of generation need to be processed, and has increased again the environment protection treating expense.And, often clean thorough not for the elongated hole on some porous parts, can stay that some are residual.Also have plenty of with metal detergent and add a certain proportion of clear water, soaking a period of time, then use the clear water rinsing clean, its shortcoming is that the effect of deoiling is undesirable, soak and the described overlong time of rinsing, process the sewage produced more difficult, disposal cost is very high.Lubricating oil be a kind of be the mixture of complicated hydrocarbon.Process general being difficult to fully by its dissolving or decomposition so use chemical method.
Also have some to remove the mode that oil and fat method adopts high-temperature process.Flash-point means an index of oil evaporation.The cut of oil product is lighter, and vapo(u)rability is larger, and its flash-point is also lower.Otherwise the cut of oil product is heavier, vapo(u)rability is less, and its flash-point is also higher.Utilize this character, at a certain temperature, lubricating oil will evaporate or burn.Oil product, under the experiment condition of regulation, is subject to the coke black residue formed after thermal evaporation and burning to be called carbon residue.Carbon residue is the important quality index of lube base oil, is the project for judging that lubricated oil properties and refining depth are stipulated.In lube base oil, carbon residue the number, not only relevant with its chemical composition, and relevant with the refining depth of oil product, the main matter that forms carbon residue in lubricating oil is: the colloid in oil, asphalitine and polycyclic aromatic hydrocarbon.These materials, under the condition of lack of air, are subject to heat-flash decomposition, condensation and form carbon residue.The refining depth of oil product is darker, and its carbon residue is less.Generally, the carbon residue of blank base oil is the smaller the better.Now, many oil products all contain the additive of metal, sulphur, phosphorus, nitrogen element, and their carbon residue is very high, and therefore the carbon residue containing additive-treated oil has lost the original meaning that carbon residue is measured.Mechanical admixture, moisture, ash content and carbon residue are all the quality index of reflection oil product purity, have reflected the degree of lubrication base oil refining.Also carbon residue can be formed even therefore use high-temperature processing method to remove lubricating oil, thoroughly clean purpose can not be reached.
The utility model patent that application number is 200920176284.4 discloses a kind of device of removing the metal tape grease, its heating furnace that uses electrothermal furnace or flame thrower is housed provides the high temperature of 300-400 ℃, metal tape is sent into the heating furnace entrance by discharger, make the grease gasification through high temperature action, and discharge carbon monoxide waste gas., this technology can only be removed the grease on strip metal, and does not possess seal, can produce waste gas, pollutes.
The utility model patent of application number 201220690135.1 has been announced a kind of steel plate degreasing unit.Comprise the steel plate transport platform, the both sides of described steel plate transport platform are equipped with support plate, between its top, two support plates, the hot blast cutter are installed, and on the steel plate transport platform of hot blast cutter both sides, cover all are housed, and the position of described cover can be adjusted, the height of described hot blast cutter also can be adjusted.Blow the high-temperature hot-air of 380 ℃ of left and right by the hot blast cutter to steel plate, the greasy dirt of surface of steel plate can be vapored away.This device has certain seal, but obturation effect is not good, can cause certain air pollution, and, can not effectively process equally the grease of the porous belts oil device inside of complicated structure.
Have, the patent of invention that application number is 94104498.X discloses a kind of degreasing unit and deoiling method of spiral tube again, and this degreasing unit is provided with stove; Have the space of accommodating disc coil and the thermal source of heating spiral in stove, above-mentioned spiral tube degreasing unit is equipped with the air supply plant of sending gas pushed away for the oil vapour in the pipe above-mentioned spiral tube; The gas of sending out from air supply plant is imported to the path of supplying gas in stove; And for the end that is communicated with the above-mentioned path of supplying gas the communication apparatus with an end of the pipe of spiral tube in stove, reach the high temperature of the evaporating state that is enough to keep oily for the temperature of gas that oil vapour is pushed away.This technology makes the grease evaporation by high-temperature heating, and by oil extraction, with gas, makes the grease evaporated discharge under evaporating state.This device can effectively be removed the grease in this part with single duct of spiral tube, but and the grease of inapplicable removal porous type mechanical part inside.
Summary of the invention
Problem to be solved by this invention is, a kind of hot cigarette negative pressure degreaser is provided, the warm flue gas of height by utilizing temperature-adjustable and oxygen content is in the forced flow effect of porous belts oil components interior, and baroque porous belts oil parts are carried out to high temperature processings of deoiling, and realizes thoroughly cleaning.
