Description
Technical field
The present invention relates to a kind of utility appliance of glass pressing machine, particularly a kind of cooling protection device for glass pressing machine operation screen.
Background technology
At Flat panel PV glass production enterprise now, rolling press is the equipment of very core, and runs under being in hot environment, and the reliability of rolling press is the important guarantee of product production and quality.Because rolling press related data needs often adjustment, must be arranged near rolling press for convenience of operation rolling press operation screen, from kiln overflow port very close to.As electric elements, under the operation screen of rolling press is in hot environment always, its life and reliability all greatly reduces.More domestic manufacturing enterprises occurred that the malfunctioning rolling press that causes of operation screen was shut down for above-mentioned reasons, and caused the accident of heavy losses.
Therefore rolling press operation screen is effectively cooled protection, paid attention to by the inner relevant enterprise of industry gradually.
The major measure taked at present has: for operation screen installs protective window; High-power water cycle cold blast engine is installed additional at operation screen annex; Install an air-conditioner; Recirculated water bag etc. is installed.
Although these modes can play protection effect to a certain extent, all there is infusion of financial resources large, running cost is high, and it is unreliable to run, and uses dangerous, and the shortcoming such as take up room large.
So exploitation is a kind of safe and reliable, economic environmental protection, installs simple, and glass pressing machine operation screen cooling system easy to maintenance just seems very urgent, through extensively retrieving, not yet finds ideal technical scheme.
Summary of the invention
The object of the invention is to solve, the infusion of financial resources that the cooling protection device of the rolling press operation screen that present stage uses exists is large, and running cost is high, it is unreliable to run, use dangerous, the shortcoming such as take up room large, and a kind of cooling protection device for glass pressing machine operation screen proposed.
To achieve these goals, present invention employs following technical scheme:
A kind of cooling protection device for glass pressing machine operation screen, comprise housing, housing is respectively equipped with water cycle cold blast engine and operation screen, described water cycle cold blast engine connects an inlet channel and an outlet conduit respectively, it is characterized in that: on described outlet conduit, connect a cyclic water tank, described operation screen connects a protective window that its sealing is covered, transparent glass is connected at the front side wall of protective window, a vortex tube refrigerator is also connected in the side of protective window, the inlet mouth of described control cooler connects compressed gas source by intake ducting, a part for intake ducting is arranged in described cyclic water tank, the cold air outlet of described vortex tube refrigerator connects outlet pipe, outlet pipe is arranged in described protective window.
On the basis of technique scheme, following further technical scheme can be had:
Intake ducting curl in described cyclic water tank.
The sidewall of described outlet pipe is provided with one group of production well.
Described transparent glass adopts LOW-E glass.
Heat-resisting thermofin is all posted in the inner side of the sidewall of described protective window.
This device installs a protective window it covered completely additional and makes it to be in closed environment before operation screen, conveniently operate and observe, the front side wall of protective window is provided with a switch gate, switch gate assembles LOW-E radiation shielding glass, LOW-E glass can stop a part of radiant heat, installs protective window and the operation screen when other operation can also be avoided to be accidentally impacted and to cause damage.
What the vortex tube refrigerator described in this device was applied is swirl control refrigeration technique, and it is also referred to as compressed air refrigeration.It is that a kind of effect by vortex tube makes high velocity air generation whirlpool isolate hot and cold two strands of air-flows, utilizes cold air stream and obtains refrigerating method.Only the pressurized air of input UP, is changed by vortex tube, and one end produces freezing air, and one end produces warm air.The flow of adjustments of gas and the height of cold air end temperature can also be come by regulating the valve of hot gas end.Use vortex tube refrigerator, safe and reliable, refrigeration does not produce any waste, non-maintaining, and device structure is simple, easy for installation, durable.
But the compressed air temperature needed for vortex tube refrigerator can not be too high, general below 50 DEG C, because vortex tube cold junction also can only provide the temperature difference about 36 degrees Celsius, if gas source temperature is too high, the cold air temperature that vortex tube is separated also can correspondingly improve, and then does not reach refrigeration.And the on-the-spot ambient temperature of rolling press is high especially, compressed air line is all in thermal environment, cannot avoid.Summer compressed air temperature can reach more than 80 DEG C.
This device enters and first carries out cooling process in cyclic water tank to the pressurized air of vortex tube.Because rolling press equipment inherently has recirculated water to cool, this device only increases a cyclic water tank in original refrigerating unit, changes less to original device, pressurized air is after cooling, its temperature is reduced to close to water temperature, is approximately 35 DEG C, and then supplies vortex tube refrigerator use.Swirl control so just can be made to produce the freezing air of about 0 DEG C, and refrigeration is strengthened greatly.To pressure-air cooling, the cooling circulating water of second stage employ rolling press, Non-energy-consumption drops into, economical and practical.
The invention has the advantages that: this equipment safety is reliable, economic environmental protection, install simple; easy to maintenance; can effectively protect rolling press operation screen, avoid the damage that operation screen causes because environment for use temperature is too high, and then avoid the loss causing rolling press disorderly closedown.
