Description
Technical field
The utility model relates to a kind of apparatus for destroying, relates in particular to a kind of demagnetization assembly that can carry out the destroying electronic storage medium device of demagnetization processing to disk.
Background technology
Along with informationalized development, various magnetic-based storage medias (as tape, disk, hard disk, magnetic card etc.) more and more are widely used in stored information.For units such as government department, army, high-tech department, finance, those information (data) that are stored on the magnetic-based storage media belong to classified information basically, can not arbitrarily abandon.Must be before abandoning them with the superincumbent information destroying of storage, to guarantee national information safety.
At present, people destroy the information that is stored on the storage medium by magnetic destruction method and mechanical destruction method.The magnetic method of destroying mainly is to utilize high-intensity magnetic field to destroy the orientation of the magnetic-based storage media disc surface magnetocrystalline particle NS utmost point, reaches the purpose of destroying the information on the magnetic-based storage media that is stored in.
ZL 200420006642.4 utilizes solenoid to destroy the information that is stored on the magnetic-based storage media.The magnetic-based storage media of the information of storing is built in the solenoid, give solenoidal two ends the logical voltage of going up, make and flow through electric current in the solenoid, produce magnetic field intensity greater than the coercitive magnetic field E of magnetic-based storage media disc surface magnetocrystalline particle, the NS utmost point orientation of the magnetic line of force destruction magnetic-based storage media disc surface magnetocrystalline particle of magnetic-based storage media is passed in utilization, thereby, realize that destruction is stored in the purpose of the information on the magnetic-based storage media.Above-mentioned magnetic destruction method is feasible for the hard disk of at present popular horizontal return to zero, but, development along with seagate, following hard disk will adopt the perpendicular magnetic recording record data, and traditional like this magnetic destroying method just can not be destroyed the information that is stored on the perpendicular magnetic recording medium.
Horizontal magnetic recording media is meant that the magnetocrystalline particle level is arranged in disc surface such as hard disk, and perpendicular magnetic recording medium is meant that magnetocrystalline particle vertical arrangement is in disc surface such as hard disks.Generally speaking, magnetic-based storage media (as hard disk) is positioned horizontally in the solenoid, because the magnetic direction that solenoid produces is consistent with the magnetocrystalline particle alignment direction of horizontal magnetic recording media disc surface, therefore, can change the NS utmost point orientation of horizontal magnetic recording media disc surface magnetocrystalline particle, reach the purpose of destroying information.But, because the magnetocrystalline particle alignment direction of magnetic direction that solenoid produces and perpendicular magnetic recording medium disc surface is 90 degree, therefore, can't change the NS utmost point orientation of perpendicular magnetic recording medium disc surface magnetocrystalline particle, can't destroy the information above it.Refer to that by machinery destruction method the information on the storage medium of destroying physical property pulverizes, because residual fraction information still above the fragment after destroying, therefore, this destroying method is not best more.
The utility model content
The purpose of this utility model is to overcome existing destroying electronic storage medium device the problems referred to above in the technical existence of demagnetization, and a kind of demagnetization assembly of destroying electronic storage medium device is provided.The utility model can carry out demagnetization to the hard disk of horizontal return to zero and the hard disk of perpendicular magnetic recording, when demagnetization is handled, the may command erasing time, guarantees the abundant of demagnetization.

The guiding wheels of described demagnetization brush roll group top are two groups.
Described guiding wheels are driven by slowspeed machine, and demagnetization brush roll group is driven by high-speed electric expreess locomotive.
Described demagnetization brush roll group comprises left demagnetization brush roll and the right demagnetization brush roll that cooperates with left demagnetization brush roll.
Described guiding wheels comprise left directive wheel and the right directive wheel that cooperates with left directive wheel.
The guiding wheels of described below are arranged with the funnel type interface channel that is communicated with crushing chamber.
Adopt advantage of the present utility model to be:
One, during the utility model demagnetization since directive wheel drive by slowspeed machine, can guarantee the sufficient erasing time, guarantee the abundant of demagnetization, demagnetization brush roll group can will have the magnetic on the sub-storage medium of magnetoelectricity surface to brush, and all can carry out the demagnetization processing to the hard disk of horizontal return to zero and the hard disk of perpendicular magnetic recording.
Two, the utility model utilizes demagnetization brush roll group to carry out the lock out operation of magnetic and magnetic sheet mainly to having the disk sheet of strong magnetic, makes that magnetic separates with disc on the disk sheet, thereby reaches the order ground of demagnetization.
Three, the utility model utilizes slowspeed machine to drive directive wheel for guaranteeing the abundant of demagnetization, guarantees that first disc can stop 4s in the demagnetization chamber.
Four, the utility model carries out demagnetization in the demagnetization chamber, and the noise when making every effort to make demagnetization drops to minimum, applicable to the office space.
Five, pulverized by the shredder assemblies of destroy machine after the utility model demagnetization again, according to the physical characteristic of electronic storage medium, make it become netted or graininess after pulverizing, dual assurance reaches irreducible order ground.
