Technical field
The utility model relates to a kind of equipment of removing the double-zero aluminum foil remained on surface ROLLING OIL after rolling, specifically a kind of aluminium foil vacuum and low temperature waste-oil scavenger.
Background technology
The application of aluminium foil is more and more extensive, people also improve constantly the requirement of aluminium foil surface quality, products such as heat-sealed foil, medicinal foil, flexible pipe paper tinsel particularly, except the surface that requires suitable mechanical property, smooth, also require the aluminium foil surface oil removing clean, to guarantee the normal use of final products.The speed of modernization aluminium foil mill is very high, just rolling complete aluminium foil surface is more or less all with ROLLING OIL, if oil removing is not thorough, the defectives such as oil is sticking, foaming, a lines, band oil, oil mark can appear in aluminium foil products, except band oil, these defectives are not periodically to occur at finished product generally, are difficult in the check finding, its origin cause of formation mainly is that the ROLLING OIL of aluminium foil surface is removed not thorough.
According to domestic and international interrelated data, the heat treatment method oil removing is generally adopted in modern aluminium foil production, mainly is the volatilization of being heated that relies on oil in the annealing process.Usually the purpose of two zero paper tinsels annealing, the one, in order to obtain certain plasticity, the 2nd, for obtain light, totally without the surface quality of Residual oil.Past is formulated the major consideration of two zero paper tinsel finished product annealing process, is the boiling range of recrystallization temperature and the ROLLING OIL of pure aluminum foil.Because the recrystallization temperature of pure aluminum foil is about 240 ~ 260 ℃, the boiling range of aluminum foil rolling oil generally is about 200 ~ 260 ℃, the annealing process that the past formulates, and annealing temperature is generally 310 ℃, annealing cycle 10 ~ 40h.This annealing schedule, because temperature is high, oil film carbochain decomposing oxidation occurs in the grease burning, causes that aluminium foil pollutes, and causes the yellowish-brown oil mark.The general way of 230 ℃ of long-time insulations that adopts is guaranteed annealing and fully oil removing or respectively oil removing and annealing of segmentation insulation at present.Long-term practice result shows: the mechanical performance of product is general only to need 10～15h annealing can reach the GB requirement, and the oil removing time then reaches 28～35h (to 0.007～0.15mm aluminium foil).The adjustment of mechanical performance and oil removing are difficult to carry out synchronously, thus the plenty of time be wasted in the oil removing annealing process, past attempts is crossed works such as annealing process, aluminium foil charging modes and is researched and analysed, adjusts and improve, but it is little all to produce effects.In traditional oil removing process, the modes such as air blast supercharging or exhausting exhaust are generally adopted in the eliminating of oil gas in the stove, and this mode is through after the heating of certain hour, discharges oil gas by the mode of air blast or exhausting.No matter but which kind of mode makes in the process of oil evaporation in heating, the gas in the stove all is immobilising, only has and just carries out an oil gas eliminating when dividing potential drop of ROLLING OIL in atmosphere tends to balance with vapour pressure by the time.The oil gas that this mode is evaporated in heating process around the oil removing aluminium foil, is unfavorable for improving oil gas evaporation speed all the time.In addition, for a large amount of medicinal aluminum foils that use of pharmaceutical industry, do not need to improve the annealing in process of the mechanical property of materials behind the aluminum foil rolling, but to having relatively high expectations of oil removing, if continue to use aforementioned anneal oil removing technique, the one side oil removing time is longer, has reduced production efficiency, higher except oil temperature on the other hand, increased unnecessary energy resource consumption.Therefore, in the urgent need to seeking the oil removing problem after a kind of energy-efficient approach solves aluminum foil rolling.

Also be provided with condensing unit 5 in the exhaust pipe between described bleeding point and the vavuum pump 6.
The method that adopts device of the present utility model to carry out oil removing comprises the steps:
(1), at first will need surface attachment to be processed to have the aluminium foil 4 of ROLLING OIL to put into pressure vessel 3.In order to guarantee the normal evaporation of aluminium foil surface oil content, avoid aluminium foil is directly piled up pressure vessel 3 bottoms as far as possible.Aluminium foil can be placed on such as on the bracing or strutting arrangements such as article holder or the suspension arrangement, be middle part or the top that aluminium foil is in pressure vessel.
(2), place aluminium foil 4 after, closed pressure container 3, the bleeding point that adopts vavuum pump 6 to arrange from pressure vessel 3 bottoms vacuumizes pressure vessel, makes the Pressure Drop to 10 in the pressure vessel
-2Below the MPa, general 10
-2MPa gets final product.
(3), after pressure vessel 3 interior vacuums reach requirement, start high frequency pulse power supply 7, the chamber wall with 8 pairs of pressure vessels of electromagnetic induction heating coil heats.Because after being evacuated in the pressure vessel, can carry out the gas flow of heat conduction seldom, the conduction of its internal heat mainly relies on thermal-radiating form.Therefore, at this moment the thermal-radiating form of main dependence heats aluminium foil.Along with the rising of temperature, the ROLLING OIL of aluminium foil surface can be evaporated gradually.By the temperature of the detection of the temperature sensor in pressure vessel aluminium foil, control high frequency pulse power supply 7 reaches the temperature of aluminium foil and remains on 60-90 ℃.
(4), with vavuum pump vessel internal pressure power is down to 10 in step (2)
-2After MPa was following, when continuation was bled with vavuum pump, the intake valve I 1 of opening pressure container top and intake valve II 2 were injected helium and air simultaneously in pressure vessel.The injection rate of control helium and air guarantees that the helium in the injection pressure container and the volume ratio of air are 1 ︰, 8-1 ︰ 10 in the same time, is preferably 1 ︰ 9.The injection of helium can guarantee that aluminium foil is not oxidized, and the helium that injects can be gathered in pressure vessel top, and along with the injection that continues, increasing gradually of helium aggregate amount can be with the oily vapour of evaporation to pressing down, thereby reduces ROLLING OIL vapor partial pressure around the aluminium foil.Guaranteeing that suitable injection air can reduce the use amount of helium under the not oxidized prerequisite of aluminium foil, thereby reducing cost.And guarantee suitable gas inject amount, can guarantee the gas flow in the pressure vessel, improve oil removal efficiency.
(5), when step (4) is injected helium and air in the pressure vessel, detect the injection rate of helium and air.Count from beginning to inject, when the helium cumulative volume that injects reach the pressure vessel volume 2/3-3/4 the time, can think that oil removing is substantially to finish.At this moment, close high frequency pulse power supply 7 stopped heatings, then close vavuum pump and stop to vacuumize, and close intake valve I 1 and stop to inject helium.The injection that keeps air is until after vessel internal pressure power and external pressure reach balance, close intake valve II 2 and stop to inject air.Then open pressure vessel aluminium foil is taken out, namely finish the aluminium foil oil removing.
In order to prevent air pollution, and ROLLING OIL recycled, when adopting vavuum pump to bleed, the gas of extracting out in the pressure vessel can be passed into first condenser, oily vapour in the gas is condensed in the process by condenser, thereby oily vapour is separated from gas, and collected, the gas after the separation discharges by vavuum pump.
