Description
Technical field
This utility model relates to a kind of vacuum equipment, particularly relates to a kind of vacuum storage device.
Background technology
Vacuum cabinet includes vacuum shelf dryer, storage in vacuum cabinet, vacuum storing cabinet, and vacuum cabinet is to allow
In vacuum state inside cabinet, store for article.Because storage environment is vacuum state, it is ensured that storage
The high-cleanness, high (1000 grades) of indoor, low humidity (relative humidity ＜ 1%).Vacuum cabinet is mainly used in
Store optical element, semiconductor components and devices, metal material, precision optical machinery, electronic component, chemical products,
Industrial chemicals, rare earth material, blue scape film, anaerobic material, oxidizable material etc. it can also be used to electronic machine,
Parts, the dehumidification of element process.Vacuum cabinet ensure that the anti-oxidation of product of storage, variable color, brown
Become, go mouldy, damage by worms, make moist, can guarantee the quality, fresh-keeping prolongation product shelf life limit.
Vacuum cabinet, after storage article put into material storage room (material storage room), is opened vacuum pump and is entered material storage room
Row vacuum suction；For energy efficient, after vacuum suction to setting working vacuum degree, just close vacuum pump,
Closing material storage room's valve, material storage room enters and keeps vacuum state.
After vacuum cabinet closes vacuum pump stopping vacuum suction, the vacuum index of material storage room can gradually degenerate
(vacuum readings uprises).This is because the existence of the various leak source of one side material storage room, such as weld seam, material sand
Eye, poorly sealed etc., on the other hand the material of making of material storage room itself exists to exit and also can reduce house vacuum
Degree.In order to keep the design vacuum in material storage room, there are two kinds of methods:
One is that vacuum pump is not shut down, and long-term start carries out vacuum suction；
Two kinds is to open vacuum pump again after vacuum drops to certain limit to carry out vacuum suction, and material storage room reaches
Turn off vacuum pump after design vacuum, enter material storage room's vacuum packing state, and so forth.
Article storage is a kind of state for a long time, and therefore former approach energy consumption is excessive, in industry generally individually
Do not use；Second method is reliable, energy-conservation, is current industry universal way.
But the common practice of vacuum cabinet is by operator's Non-follow control vacuum pump startup-shutdown at present,
Operator's execute-in-place checks vacuum index, finds that vacuum index, less than after design objective, is manually controlled
System opens vacuum pump, carries out vacuum suction, and after vacuum index reaches, then Non-follow control closes vacuum pump
Entering vacuum pressurize, and so forth, this operator scheme needs scene to have human attendance, and all manual operations,
Waste time and energy, inefficient；And this operation there is also following drawback: storage article are put into by operator
After material storage room, close material storage room's door, need opened manually vacuum pump again that material storage room is carried out vacuum suction,
These operator need two operating procedures just can complete article storage work, and sometimes, operator can forget
Note opens vacuum pump, under serious conditions, the article of storage can be caused to damage.
Utility model content
In view of the foregoing, this utility model provides a kind of vacuum cabinet, and its scheme is: a kind of vacuum is deposited

Having vent valve, microprocessor controls vent valve is in order to exit to material storage room；Described material storage room is additionally provided with very
Empty room door sensor, in order to produce door for vacuum chamber switching signal, and by the output of door for vacuum chamber switching signal to micro-
Controller, is controlled vacuum pump by microcontroller according to switching signal and material storage room is carried out vacuum exhaust.
Described vacuum cabinet, is additionally provided with indoor LED illuminating lamp in the material storage room of described vacuum cabinet,
When material storage room's door is opened, door for vacuum chamber sensor produces door for vacuum chamber switching signal, and is opened by door for vacuum chamber
OFF signal exports to microcontroller, microcontroller open storing indoor LED illuminating lamp according to switching signal；
When material storage room's door is closed, door for vacuum chamber sensor produces door for vacuum chamber switching signal, and is opened by door for vacuum chamber
OFF signal output closes storing indoor LED illuminating lamp to microcontroller, microcontroller.
Described vacuum cabinet, described vacuum measuring device is pressure transmitter, and described pressure transmitter is examined
When survey material storage room vacuum reaches minimum vacuum setting value, microcontroller receives what pressure transmitter transmitted
Open vacuum pump, air bleeding valve after vacuum signal successively, material storage room is carried out vacuum exhaust, until pressure becomes
When sending device detection material storage room vacuum to reach setting value, microcontroller receives the vacuum that pressure transmitter transmits
Signal closes air bleeding valve, vacuum pump successively, and material storage room enters vacuum hold mode.
Preferably, the pressure transmitter of described vacuum cabinet can be resistor pressure transducer.
After using technical scheme described in the utility model, described vacuum cabinet can true in its material storage room
Sky keeps automatically, can automatically carry out vacuum exhaust and material storage room's intraoral illumination when switching material storage room's door,
It is easy to operate, and efficiency is high, has saved manpower and the energy, has decreased the dependence to operator, prevents behaviour
The operational error making personnel stores the damage of article to vacuum cabinet.
