Description

Magnetic recording media product conservator

The utility model belongs to preserves the air dehumidifier filtration unit that the magnetic recording media product is used.

It is to adopt hygroscopic agent that air is carried out moisture absorption that existing disk phonotape and videotape band mildew-resistant cabinet solution disk phonotape and videotape is with the way of going mouldy of making moist, the mildew-resistant cabinet of this structure is simple, but because it is to adopt the hygroscopic agent moisture absorption, thereby hygroscopic capacity is little, low and the hygroscopic agent of the efficient of moisture absorption is easy to wear out, must often change hygroscopic agent, therefore, the volumetric ratio of this mildew-resistant cabinet is less and moisture absorption efficient is not high.

But the purpose of this utility model provides the magnetic recording media product conservator that a kind of technical maturity, the dehumidifier of dehumidifier efficient height purify air.

The utility model comprises metal cabinet, air dehumidifier apparatus, air filtering dust-removing device and electrical control gear, the metal cabinet is divided into upper, middle and lower-ranking, the upper strata is a preserving chamber, the middle level is air dehumidifier chamber, the evaporator of the blower fan of dust removal by filtration device, air dehumidifier apparatus and condenser are contained in air dehumidifier chamber, lower floor is a compressor room, and the compressor of air dehumidifier apparatus is contained in compressor room; One side of metal cabinet has the air channel, and upper filter screen is equipped with in the junction of air channel and preserving chamber, and lower filter screen is equipped with in the junction of preserving chamber and air dehumidifier chamber.Electrical control gear of the present utility model is made up of humidity controller, power switch, alarm switch and wiring board, and humidity controller is contained in the bottom of preserving chamber.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is the cut-open view of the utility model embodiment.

Fig. 2 is the electrical schematic diagram of the electrical control gear of the utility model embodiment.

With reference to Fig. 1, Fig. 2, metal cabinet 1 is made up of upper, middle and lower-ranking, and the upper strata is a preserving chamber 16, and the middle level is that air dehumidifier chamber 13, lower floor are compressor room 10.Preserving chamber 16 is the places of depositing the magnetic recording media product, and blower fan 11, evaporator 5 and condenser 6 are equipped with in air dehumidifier chamber 13, and compressor 8 is equipped with in compressor room 10; Be concatenated into sealing system with copper pipe 7 and kapillary 4 between compressor 8, condenser 6 and the evaporator 5.This system becomes air dehumidifier apparatus of the present utility model through vacuumizing and pour into an amount of cold-producing medium.During this device work, because cold-producing medium enters the sharply vaporization evaporation of evaporator 5 backs, and evaporator 5 surface temperatures are reduced between 1 ℃-5 ℃, this temperature is very suitable to make water in air part be condensed into the globule, thereby reach the purpose of air dehumidifier, globule condensation polymerization is injected drip tray 9 by flexible pipe.When blower fan 11 starts, air is attracted to malaria in the preserving chamber 16 in the air dehumidifier chamber 13 by lower filter screen 14 by blower fan 11 suctions, air-flow is cooled off by evaporator 5 surfaces, wherein moisture content condenses because of evaporator 5 surface temperatures are lower than the air dew point temperature, pass through the oily air-flow that wets and be cooled when condenser 6, the heat heat temperature raising that the device 6 that is condensed distributes, relative air humidity descends, after air channel 3 by the side enters upper filter screen 2 dust removals by filtration, flow back to preserving chamber 16.When blower fan 11 started, the direction of air flow was shown in Fig. 1 arrow.In addition, 13 front ends are equipped with circuit board module 12 in air dehumidifier chamber, in the bottom of preserving chamber 16, near lower filter screen 4 places humidity controller 15 are arranged.Use the flexible circuit conductor energized between circuit board module 12, humidity controller 15, compressor 8 and the blower fan 11.

As can be seen from Figure 2, electrical control of the present utility model is adopted dehumidifier circuit 17, filtering circuit 18 and warning circuit 19 and is connected and forms.The work of unit is subjected to humidity controller 15 controls, when the relative air humidity in the preserving chamber 16 during greater than certain value, the contact auto-closing energized of humidity controller 15, dehumidifier and filtration begin to carry out, relative air humidity begins to descend in the preserving chamber 16, is lower than certain value when relative humidity drops to, the automatic separation cut power supply in the contact of humidity controller 15, dehumidifier and filter process finish, and wait for next working cycle.Because metal cabinet 1 is to make with metal, so the utility model is the metal box of an enclosure-type, it has magnetic screening action preferably and diamagnetic interference performance, has weakened the influence of external magnetic field field to the magnetic recording media product than large program.In addition, it also has and opens and closes cabinet behind the door, and air carries out the delay control circuit 20 of dust removal by filtration and the overlong time or close the door tight and send the delay control circuit 21 that buzzing is reported to the police of opening the door automatically in the cabinet.

The utility model moisture-exhausting amount is big, dehumidifier efficient height, strong, the behaviour of diamagnetic interference performance Do easy, memory capacity is big, safe and reliable, be fit to the long preservation magnetic recording media and produce Product, it suits to use in office, enterprise, bank, school.
