Description
Technical field
The utility model relates to field of machining and machinebuilding technology, further relates to grease removal device, and particularly a kind of hot cigarette negative pressure degreaser can be removed the grease of porous belts oil components interior.
Background technology
In industrial products manufacture process, in order to meet processing technology needs or the needs based on protection process equipment, in part mechanical part process, conventionally adopt lubricating oil as the lubricant medium in component processing process or cooling medium.For meeting the requirement of product cleannes, after component processing completes, need parts surface and inner grease thoroughly to remove, otherwise not only easily adhesion dust and other foreign material of residual grease, and can affect next step processing or assembling procedure.The thorough removal of porous type mechanical part internal grease is the difficult problem that puzzlement product efficiently, thoroughly cleans all the time.
The methods that great majority are removed greases adopt the mode of Chemical cleaning, after having plenty of and processing 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 environment protection treating expense.And, often clean thorough not for the elongated hole on some porous parts, can leave 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 clear water rinsing clean, its shortcoming is that the effect of deoiling is undesirable, overlong time described in immersion and rinsing, processes the sewage producing more difficult, and disposal cost is very high.Lubricating oil be a kind of be the mixture of complicated hydrocarbon.Process general being difficult to completely by its dissolving or decomposition so use chemical method.
Also have some to remove the mode of oil and fat method employing high-temperature process.Flash-point is an index that represents 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 forming 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 stipulate.In lube base oil, the number of carbon residue, not only relevant with its chemical composition, and also relevant with the refining depth of oil product, the main matter that forms carbon residue in lubricating oil is: colloid, asphalitine and polycyclic aromatic hydrocarbon in oil.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, have therefore lost containing the carbon residue of additive-treated oil 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 object can not be reached.
Application number is that 200920176284.4 utility model patent discloses a kind of device of removing 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 heating furnace entrance by discharger, make grease gasification through high temperature action, and discharge carbon monoxide waste gas., this technology can only be removed the grease in 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 steel plate transport platform, the both sides of described steel plate transport platform are provided with support plate, between its top, two support plates, hot blast cutter are installed, and in the steel plate transport platform of hot blast cutter both sides, cover are all 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 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; In stove, have the space of accommodating disc coil and the thermal source of heating spiral, above-mentioned spiral tube degreasing unit is equipped with the air supply plant of sending gas for the oil vapour in the pipe of above-mentioned spiral tube is pushed away; The gas of sending out from air supply plant is imported to the path of supplying gas in stove; And for being communicated with the communication apparatus of one end of the above-mentioned path of supplying gas and one end of the pipe of spiral tube in stove, reach for the temperature of gas that oil vapour is pushed away the high temperature that is enough to the evaporating state that keeps oily.This technology makes grease evaporation by high-temperature heating, and makes the grease having evaporated discharge under evaporating state with gas by oil extraction.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.
