Description
Technical field
The present invention relates to the bottle blowing machine field, be specifically related to a kind of air supply system of bottle blowing machine.
Background technology
Energy-saving and emission-reduction, low-carbon economy, protection environment are the main keynotes of the world today, and the plastics package industry developed very fast in recent years, have become with the energy rich and influential family, and compressed air then is during plastics package enterprise produces, the working media of energy consumption maximum.
At present, most of bottle blowing producer is still and presses air compressor machine supply draft cylinder work gas and bottle blowing to blow in advance in the employing in the plastics package industry, and as shown in Figure 1, and High Pressure Air Compressor only blows the mode of supplying high pressure gas for the bottle blowing master, as shown in Figure 2.Its gas johning knot composition as shown in Figure 3, middle air and the pressure-air of pressing is by high-pressure pipe 11, in compress into tracheae 12 and enter gas distributor 13 after, the pressure-air that is come out by gas distributor 13 is delivered to each die cavity by the high-pressure air pipe branch multifunctional electromagnetic valves is led the bottle embryo of stretched and pre-blowing and is blown, make bottle outer wall be close to die cavity wall, and bottle is finalized the design, solidify, the middle pressure air that comes out by the gas distributor, deliver to gas tank 14 by conveyance conduit, the middle pressure air that is come out by gas tank is sent to presses draft cylinder and bottle blowing machine to blow the device interface in each, decompression is sent to low pressure stretching control interface for low-pressure air to another part through pressure-reducing valve.
Adopt this gas transmission connected mode, blowing over a large amount of high pressure residual air of bottle directly discharges, these pressure-airs all are to have consumed a large amount of electric energy to produce and get, on the one hand a large amount of energy is wasted in vain, its energy utilization rate is very low, and the NOISE ON ENVIRONMENT that produces when the discharging high pressure gas also pollutes, and also will expend a large amount of precious water resource simultaneously and cool off.Learn according to our data of measuring and calculating from practice, the PET bottle of a 600ml will consume the electric energy more than the 1W approximately at pre-blowing during the stage (power consumption when not containing main blowing), if the PET bottle of the annual all size of blowing in the whole nation is converted to the PET bottle of 8,000 hundred million 600ml, the then annual electric energy that will consume 8,000 hundred million W, the i.e. electric energy of 800,000,000 KW (that is 800,000,000 degree), this is equivalent to two days gross generation of the three gorges hydropower plant full load, adds the energy consumption of cooling water, will surpass 1,000,000,000 degree.Therefore, its energy-saving potential is very big.
Summary of the invention
The object of the present invention is to provide the air supply system of a kind of energy utilization rate height, bottle blowing machine that environmental pollution is little, to save the energy, protection environment and to increase economic efficiency.
The air supply system of a kind of bottle blowing machine of the present invention, comprise the high pressure admission interface, the gas distributor, gas tank and the conveyance conduit that is connected usefulness, pressure-reducing valve, overflow valve, pressure-air enters the gas distributor by the high pressure admission interface, a high-pressure outlet by the gas distributor connects the pressure-reducing valve inlet end, connect gas tank by middle air pipe, the other high pressure interface of giving vent to anger is connected to high-pressure control device by main blowpipe, gas tank connects the pressure-reducing valve upstream end and is delivered to each low voltage control device or is delivered to middle pressure control device by middle air pipe by the low pressure tracheae, also comprise the recovery gas acquisition port that is installed on the bottle blowing mould place, reclaim gas acquisition port collection high pressure recovery gas and be delivered to recovery gather qi together pipe gather qi together by reclaiming the gas collection tube, the overflow valve inlet end connects the gather qi together pipe, and the outlet side connects gas tank.
Preferably, described gas tank is linked to each other with the gas distributor by middle air pipe, provide the middle air of pressing to export pressure control device in each to by the gas distributor, gas tank connects the pressure-reducing valve inlet end, the pressure-reducing valve outlet side is connected to the gas distributor by the low pressure tracheae, distributes low-pressure air to export each low voltage control device to by the gas distributor.
Preferably, described pressure-air is 4.0MPa, and middle pressure air is 1.2MPa, and low-pressure air is 0.7-0.8MPa.
Adopt the scavenger system of bottle blowing machine of the present invention, after pressure-air enters the gas distribution from the high pressure admission interface, air-flow is directed at the pressure-reducing valve step-down one-tenth from the outlet of gas distributor high pressure gas and presses air, be delivered to gas tank by middle air pipe, in gas tank after the voltage stabilizing, by pressing pressure-controlled and pre-bottle blowing usefulness in the air conduct in the middle air pipe output, another part is made low voltage control usefulness by exporting by pressure-reducing valve decompression back.After pre-blowing is finished, the multifunctional electromagnetic valves interface that pressure-air is delivered to the high pressure gas branch each die cavity from the high pressure gas distribution interface and the high-pressure air pipe of gas distributor, to stretched and pre-blowing and lead and blow, make bottle outer wall be close to die cavity wall, and make bottle typing, curing, reach the bottle type requirement of setting.The main high pressure bottle blowing gas that blows after finishing is then reclaimed in the gas gather qi together pipe through reclaiming the gas collection tube, receive to collect by the return-air acquisition port, then through pressure-reducing valve send in the gas tank as the next bottle blowing cycle calm the anger in needed and low pressure gas with standby.Compared with prior art; the pressure of the required exhaust of apparatus of the present invention reduces greatly; originally exhaust is a pressure-air; pressure-air is recycled substantially now; thereby the noise when making exhaust reduces significantly; help environmental protection, evacuation time also shortens greatly, helps enhancing productivity.Simultaneously, after the bottle blowing cycle in a chamber finishes, press in can from gas tank, providing and low-pressure air output, can save the input of a large amount of middle pressure air, press the spent resource of air in the manufacturing thereby can reduce, reduce the production cost of manufacturer, increase economic efficiency.
