Abstract
The present invention relates to a kind of purified compressed air supply unit.The major technique feature is be linked in sequence behind air compressor gas cylinder, oil and water seperator, precooler, lyophilizer, filter and compressed air outlet port.Can obtain water content below 760ppm behind the power supply of connection air compressor and freezing type drier, the rate of deoiling is the power source that 99.99% pure pressurized air can be made various Pneumatic actuator.
Description
The present invention relates to air feeder, particularly a kind of purified compressed air supply unit.
Pressurized air because safe in utilization, control is convenient, cost is lower, thereby is used as power source widely in fields such as Pneumatic actuator, application, winding-up, conveying.Pressurized air contains impurity such as moisture that volume exists with water vapor, droplet form and dust from atmosphere, air itself, through again machine oil that contained deterioration behind the air compressor more, therefore by moisture that contains PPM up to ten thousand in the pressurized air that air compressor provided and the greasy dirt about 45PPM, undressed pressurized air is a kind of inferior thick gas.Cause the pneumatic equipment fault that its efficient is reduced easily with this thick gas source that is used as power, the lost of life is also had a strong impact on product quality.For example: Guangzhou musical instruments factory produces Violin, owing to contain considerable moisture in the pressurized air that is used for spraying paint, and causes numerous air-bubble at coating surface, causes paint quality not reach pre-provisioning request and can not export, and causes that product is large quantities of to be overstock; Cigarette factory's big pressurized air of employing water content turns over conveying cut tobacco can make cigarette go mouldy; Terylene factory uses the big pressurized air of oil content can make dacron dyeing not reach requirement; Pneumatic instrument on the production line then can cause the control accuracy misalignment to lead to production accident because of the greasy dirt in the pressurized air; Some is with stipulating then in the gas field that compressed-air actuated water content must must be lower than 8PPM less than 1000PPM greasy dirt content.Therefore press for a kind of air feeder that can produce purification of compressed air.
Purpose of the present invention will provide a kind of improved compressed air supply unit exactly.Can obtain all very low purification of compressed air of impurity content such as moisture, dust, greasy dirt with this air feeder.
Task of the present invention is finished as follows.
Purified compressed air supply unit has support, motor, driving belt, belt pulley, air compressor, and its characteristics are be linked in sequence behind the air compressor gas cylinder, oil and water seperator, precooler, freezing type drier, filter and compressed air outlet port.
Precooler of the present invention can be made up of radiating fin and the fan of crossing tracheae, be fixed on the tracheae.
The thick destiny amount of pressurized air of air compressor output, pressure are all unstable in the purified compressed air supply unit of the present invention, and therefore temperature disposes gas cylinder and make the thick gas cooling of pressurized air, keep-up pressure and stablize and certain gas consumption up to 100 ℃.The pressurized air that is come out by gas cylinder is through removing 99% moisture that exists with the droplet form and about 40% mist of oil behind the oil and water seperator, the compressed air temperature of coming out through oil and water seperator is also quite high, in precooler through fan, after the radiating fin heat radiation, the compressed air temperature of crossing in the tracheae can be reduced to below 40 ℃, the pressurized air of lower temperature is provided for freezing type drier, described pressurized air can be clean the moisture removal that exists with the water vapor form in the pressurized air behind freezing type drier, and it is quite pure to filter the pressurized air of being exported by the air outlet back through filter at last.The pressurized air water content that obtains with air feeder of the present invention is below 760PPM after tested, and the rate of deoiling is 99.99%, is a kind of pure pressurized air, can make the power source of various Pneumatic actuator.
Below with reference to embodiment's accompanying drawing structure of the present invention is described in further detail.
Fig. 1 is that the thick gas of pressurized air purifies fundamental diagram.
Fig. 2 is the organigram of oil and water seperator.
Fig. 3 is the precooler organigram.
Fig. 4 is the fundamental diagram of freezing type drier.
Fig. 5 is the organigram of air heat exchanger in the freezing type drier.
Fig. 6 is the organigram of filter.
Fig. 7 is the D structure schematic representation of air feeder of the present invention.
Consult Fig. 2, oil and water seperator 7 is made up of the netted core 12 of washable stainless steel, interchangeable glass fibre layer 13, the netted core 12 of stainless steel utilizes centrifugal force can separate 10 μ or bigger solid particles, glass fibre layer 13 can filter 23 μ or bigger solid particles, and the thick gas of pressurized air can be removed the moisture content of 99% liquid form and about 40% mist of oil after oil and water seperator 7 filters.Consult Fig. 1, Fig. 3, precooler 8 is formed by crossing tracheae 14, radiating fin 15 and fan 16, the compressed air temperature of being come out by oil and water seperator 7 is also quite high, compressed air temperature can be dropped to through precooler 8 and to consult Fig. 4, Fig. 5 about 40 ℃, freezing type drier 9 is made up of refrigeration system and air heat exchanger two large divisions.Refrigeration system is made up of vaporizer 17, compressor 18, condenser 19, the throttling arrangement 20 of routine, air heat exchanger comprises cylinder 21,22, cylinder 21 two ends are respectively equipped with compressed air inlet 23, outlet 24, cylinder 21 center fixed had tracheae group 25, cylinder 22 1 ends are provided with cyclone separator 26, cyclone separator 26 lower ends are provided with automatic water trap 27, vaporizer 17 in the refrigeration system stretches in the cylinder 22, refrigeration system and air heat exchanger are organically linked together, and cylinder 21,22 is tightly connected by two roundlet tubes 28 29.Oil and water seperator 7 can only remove moisture content and the part greasy dirt that exists with liquid droplet form in the pressurized air, can not remove the water vapor that exists with gaseous form in the pressurized air, so the pressurized air that comes out through oil and water seperator 7 and precooler 8 is a kind of about 40 ℃, the air that contains water vapor, the pressurized air of this humidity enter by air intlet 23 carry out behind the cylinder 21 of heat exchanger pre-cooled, the part water recovery is become liquid water droplets, pressurized air enters the refrigerant evaporator in the cylinder 22 then, pressure is cooled to the evaporating temperature (about 1.6 ℃) of refrigerant, makes most water vapors be condensed into water droplet.Rely on the effect of cyclone separator 26 that water droplet is separated with pressurized air.Liquid water is by outside automatic water trap 27 collections and the discharge machine, and dry pressurized air enters the cylinder 21 of air heat exchanger once more, escapes and enter filter 10 through tracheae group 25 by compressed air outlet 24.Become in the process of drop in water recovery, the oil droplet that also congeals into simultaneously of a part of mist of oil in the pressurized air is outside the discharge machine.Consult Fig. 1, Fig. 6, filter 6 inside are made up of laminated glass fiber 30, microfibril 31, can filter 1 μ or bigger solid particles, and the function that lowers pressure drop is arranged.Porous type outer cylinder 32 can make the air after the filtration flow to the outlet of filter 6 thus rapidly.Can remove 100% moisture and mist of oil greatly partly through filter 6 back pressurized air.
Consult Fig. 1, Fig. 7, when this air feeder uses, connect the power supply of motor 2 and freezing type drier 9 earlier, motor 2 startings are after driving belt 3, belt pulley 4 drives air compressor 5, the thick gas of pressurized air that is produced by air compressor 5 enters gas cylinder 6, can obtain about 40 ℃ behind oil and water seperator 7 precoolers 8, remove the purer pressurized air of liquid water droplets and part mist of oil, again through freezing type drier 9, filter 10 and compressed air outlet 11 output water content are below 760PPM, and the rate of deoiling is that 99.99% pure pressurized air is a kind of high-quality Pneumatic actuator power source.
