Description

Dustless storeroom of archives

Technical Field

The invention relates to the technical field of archive management, in particular to an archive dust-free storage room.

Background

The book sterilizer is a special equipment for sterilizing and disinfecting the files and books and materials. It adopts microcomputer automatic control technology, can kill colibacillus, staphylococcus aureus, hepatitis germ, mould and various pests which are contaminated in the files and books, and the user can select different control time according to the contamination degree of the files and books to sterilize.

The books or the files are sterilized and disinfected by adopting a book sterilization and disinfection machine, so that the cost of book and file management is increased; the archive management is different from the book management in that the frequency of turning over the archives is relatively low compared to the frequency of turning over the books. In order to reduce the cost of archive management, it is common to enclose the archives in a sealed storage compartment; however, if the air in the storage room is not updated for a long time, when the manager enters the storage room to manage the files or turn over the files, the manager will feel uncomfortable due to the fact that the manager cannot breathe the fresh air. Therefore, when a manager enters the storage room for archive management, air renewal needs to be performed inside the storage room. Because when the air is renewed, dust in the outside air is easily carried into the storage chamber, the dust may contain worm eggs and bacteria, and the worm eggs and the bacteria will gradually breed to form moth after entering the storage chamber, thereby damaging the files.

As shown in fig. 2, the condenser 253 is provided with a water inlet pipe and a water storage pipe, the water inlet pipe of the condenser 253 is connected with a water pump, and the water pump is disposed in a water source, which is a water tank in this embodiment; the drain pipe 32 of the condenser 253 extends to the exhaust square pipe 31, and the drain pipe 32 is coiled along the inner wall of the exhaust square pipe 31 and then extends out of the exhaust pipe 25. The dryer 254 in this embodiment is an industrial dryer 254 for ease of procurement and installation. A water guide groove 255 is formed in the inner wall of the exhaust pipe 25 between the dryer 254 and the condenser 253, the water guide groove 255 forms a low-lying part, and part of condensed water is gathered in the exhaust pipe 25 and finally gathered in the low-lying part of the water guide groove 255, so that the water is conveniently led out.

The specific implementation process is as follows:

when the storage room in the embodiment is used for storing files, the air in the storage room 10 needs to be updated regularly; particularly, when a person enters a filing room to arrange files, it is necessary to refresh the air in the storage room 10.

When the air in the storage chamber 10 is renewed, water is firstly added into the water storage chamber 23 and the air inlet one-way valve 256 is submerged; then, the heater 24 and a water pump supplying water to the condenser 253 are turned on, and finally, a driving motor driving the first piston 22 to reciprocate is turned on. The driving motor drives the first piston 22 to reciprocate, and when the first piston 22 moves upwards, the cylinder 21 sucks air through the air inlet one-way valve 256; when the first piston 22 moves downward, the first piston 22 compresses the air in the cylinder 21, and when the first piston 22 moves to the bottom dead center, the first piston 22 opens the pressing valve 251, and the pressure in the cylinder 21 increases to the maximum, and the air in the cylinder 21 is rapidly ejected through the pressing valve 251. In addition, the external air will pass through the water in the water storage chamber when entering the tub 21, so that the dust in the air will be adsorbed in the water; when the first piston 22 moves to the bottom dead center, the pressure in the cylinder 21 is the maximum, and the temperature of the water in the water storage cavity 23 can reach the maximum, so that the air in the cylinder 21 can be sterilized at high temperature and high pressure, and bacteria can be prevented from entering the storage chamber 10 to propagate.

The air flow discharged from the pressing valve 251 flows forward at an extremely high speed, and when passing through the turbine 252, the air flow drives the turbine 252 to rotate, and then passes through the condenser 253; the air flow passing through the condenser 253 can liquefy the water vapor carried in the air flow and reduce the water content of the air flow, and the condenser 253 can reduce the temperature of the air flow. The airflow finally passes through a dryer 254, which dryer 254 further removes moisture from the airflow, and the final airflow enters the storage compartment 10. Most of the moisture in the air flow is condensed by the condenser 253 and then collected in the water chute 255 between the dryer 254 and the condenser 253, and the condensed water is led out.

The turbine 252 rotates and drives the second piston 261 to reciprocate up and down, so that the inflator continuously supplies air to the air tank 267, and the air pressure in the air tank 267 increases and finally reaches a stable value under the action of the pressure limiting valve. The gas box 267 is used as a gas source to supply gas to the cylinder 33; because the drain pipe 32 of the condenser 253 extends to the interior of the exhaust pipe 25 to be coiled, and after the condenser 253 absorbs heat, the temperature of condensed water in the drain pipe 32 is higher, so that the temperature in the exhaust pipe 25 is increased; therefore, the bimetal 37 deforms and drives the blocking piece 36 to bend at one side of the pressure relief opening 35, so that the blocking piece 36 blocks the pressure relief opening 35, the gas in the cylinder 33 cannot be discharged, the cylinder 33 extends and pushes the baffle 34 to rotate, and the exhaust square pipe 31 is opened.

As the wind pressure inside the storage chamber 10 gradually increases, the air at the bottom of the storage chamber 10 is discharged through the exhaust duct 25, thereby completing the renewal of the air inside the storage chamber 10. When the air intake mechanism 20 stops supplying air into the storage chamber 10, no hot air flows through the condenser 253, so that water in the drain pipe 32 of the condenser 253 becomes cold water, the temperature in the exhaust square pipe 31 is reduced, the bimetallic strip 37 drives the blocking block 36 to bend towards the side far away from the pressure relief opening 35, so that air in the air cylinder 33 is exhausted through the pressure relief opening 35, the air cylinder 33 gradually contracts, and the exhaust pipe 25 is closed by the baffle 34.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
