Description

The destroy device of hard disk, CD and semiconductor storage body

Technical field

The present invention relates to the destroy device of a kind of hard disk, CD and semiconductor storage body, this equipment belongs to information security and takes precautions against the field.

Background technology

The level of confidentiality of the tenth state secret of the Law of the People's Republic of China on Guarding State Secrets that on April 29th, 2010 revision is passed through is divided into top secret, secret, secret three grades.The top secret state secret is most important state secret, and leakage can make national security and interests suffer the infringement of especially severe; Confidential state secret is important state secret, and leakage can make national security and interests suffer severe impairment; The confidential state secret is general state secret, and leakage can make national security and interests sustain damage.Be the loss that prevents to divulge a secret and bring, confidential document is the most effective way in the timely destruction of reading after using, the destruction of confidential document comes down to the carrier of record confidential document information is destroyed, and the carrier of confidential document information mainly contains paper medium (printed matter), magnetizing mediums (magnetic drum, disk, tape etc.), light medium (CD) and semiconductor medium forms such as (USB flash disk, CF card, SM card, SD card and memory sticks etc.).

The destruction of confidential document will guarantee that secret information can not be reduced.Paper medium confidential document with the longest history adopted and burns or the method for papermaking making beating, the papery confidential document thoroughly can be destroyed, and can satisfy the requirement of information security fully.Along with the develop rapidly of the network information technology, the foundation of OA system and the popularization of paperless office, the quantity of papery confidential document is little by little reducing, and the quantity of magnetizing mediums, light medium and semiconductor medium confidential document increases constantly, and this has proposed a new difficult problem for the destruction work of classified document.Current, successively the release of the new technology that corresponding both at home and abroad confidential document is destroyed, new equipment.Destroying relevant technology, equipment with the hard disk confidential document just has a variety of:

1, utilize professional equipment and special software that the classified information in the hard disk (containing: desktop computer hard disk, notebook computer hard disk, portable hard drive and duplicator hard disk etc.) is destroyed, the method of destroying is according to security requirements, classified information is destroyed in the format (i.e. manifolding) that hard disk is carried out 30 times, and hard disk can also be reused.

Can also carry out with similar approach: the destruction of the classified information of memory bank inside such as floppy disk, erasable optical disk, USB flash disk, CF card, SM card, SD card and memory stick.

This kind destroying method is that software is destroyed method, though this law is not carried out the destruction of physics to storage mediums such as hard disks, can utilize again to economize on resources, but the classified information of storage medium inside such as hard disk still might be decrypted out, exists certain risk for the file of destroyer level of confidentiality, top secret.

2, XBF-01 type storage medium pulverizer is a storage medium pulverizer that can use in office, is fit to pulverize: hard disc, floppy disk, CD and semiconductor storage body (as: USB flash disk, CF card, SM card, SD card, memory stick and IC-card etc.) etc.This pulverizer integrates active forces such as punching press, stretching, cutting, and storage medium is carried out physically thorough pulverizing, and the particle of pulverizing the back medium is also littler than the big grain of rice, guarantees that classified information can't be read out, reduce, and meets the requirement that classified document is destroyed.

3, XBF-HD type hard disc destroyer, this equipment is mainly used in to be destroyed hard disc, in view of hard disc is the characteristics of aluminium matter, be difficult in office, cut into fine particle easily, this equipment is taked rolling method, disc is pressed into corrugated, have intensive impression simultaneously, the user also can repeatedly roll the disc rotation, and this equipment carries out physically processing to storage medium, guarantee that classified information can't be read out and reduce, meet the requirement that classified document is destroyed.

4, application number is 200920226317.1 patent of invention, has introduced a kind of hardware destroy device, and this device " microwave energy hardware destroy equipment development " belongs to Shandong Province's technological innovation project, has passed through provincial-level appraisal.This device adopts uhf electromagnetic wave that hard disk integral is heated, can thoroughly melt, destroy by fire devices such as hard disk in 15 minutes, and finally be melt into and be the alloy agglomerate, thoroughly destroy from physical arrangement, guarantee that classified information is irrecoverable, meet the requirement that classified document is destroyed.

It is introduced that this installs the exhaust-gas treatment structure more many circulating combustions circulate and absorb, efficiently solve the purifying problem of waste gas, be applicable to that gaseous mass requires than higher indoor environment.

5, application number is 201020046742.5 patent of invention, a kind of high-temp combustion and purifying processing device have been introduced, this device is to research and develop for destroying hard disk specially, the temperature of its furnace chamber can be elevated within 5 minutes more than 1700 ℃, this device can use under working environment, once can melt 3-5 piece hard disk simultaneously, and only 6 minutes time of need just can wipe out the data in the hard disk, guarantee that classified information is irrecoverable, meet the requirement that classified document is destroyed.

It is introduced that this device also can make a large amount of pernicious gases and the impurity that burn the back generation fully be filtered and purify, after burning is finished simultaneously, can reduce the high temperature of burner hearth fast.

But 2,3 two products are when destroying hard disc, at first all will disc be sent in the said equipment destroy again with hard disk through a series of disc of disassembling, take out inside.Disc manually retract complexity and workload very big from, increase the link of divulging a secret undoubtedly again on foot, actual operability is not strong.

Though 4,5 two filtration and purifiers that patent is all stated pernicious gas and impurity are set in equipment can guarantee that a large amount of pernicious gases and impurity that hard disk produces are fully handled when high temperature incineration, fusing, do not have harm to indoor environment.

The professional who is engaged in castoff burning is very clear: not only contain strong carcinogenic substances such as BaP, bioxin in the pernicious gas that produces when electronic waste burns, also contain heavy metal steams such as mercury, lead, cadmium, the purified treatment of these pernicious gases is a great problems of environmental protection industry (epi), if these two skinny devices can solve this difficult problem technically, then the electronic waste recycling just has been readily solved to the difficult problem of the harm of atmospheric environment.Hardware destroy equipment then is " Xiao Wu " by contrast!

Simultaneously, 4,5 two patent equipments produce a large amount of heat energy when the high temperature melting hard disk, bring influence can for indoor environment! Also have, whether the high temperature melting hard disk should consider the energy consumption problem of equipment.Slight hardware destroy what is the need is made a fuss over a trifling matter!

Having many problems and shortcomings just because of above-mentioned hardware destroy equipment, can provide new technology, the new equipment of a hardware destroy that cover is safe and reliable, reality is feasible, simple to operate for society, also is the call that classified papers are destroyed industry.

" the destination of study is to use entirely ", the profundity of its technology is not only pursued in innovation and creation, more the social effect that should pay attention to polytechnic practical application and be produced.

The content of invention

The technical problem to be solved in the present invention just provides a kind of destroy device of convenient and swift, safe and reliable hard disk, CD and semiconductor storage body, this equipment adopts the method for the punching press that we know that hard disk, CD and semiconductor storage body are carried out whole compression failure, make its inner stored information not to be read out, and then reach the purpose of destroying classified information.

If will destroy hard disk effectively; a preliminary understanding at first will be arranged the structure of hard disk: the front of hard disk be sealing stainless steel top cover, open top cover as seen the hard disc of aluminum (memory bank of information), disc rotation motor, disc read-write head, voice coil motor, permanent magnet and magnetic head deflection circuit etc. arranged; the back side of hard disk be steel back of the body lid, open back of the body lid as seen circuit board and sponge neonychium etc. arranged, mid portion is the hard disk disk body of cast aluminium.

Hence one can see that, and desire is taken out disc and destroyed, and hard disk top cover and inner spare and accessory parts can only be removed one by one, then could take out disc, and the method for this destruction hard disk information wastes time and energy, also is difficult to extensive employing.

The destroying method of hard disk of the present invention need not hard disk is disassembled, and directly hard disk is carried out whole punching press and destroys, and destroys that process is simple, easy operating, significantly reduces workload, has also reduced the link of divulging a secret and has avoided divulging a secret, and increases the security of destruction process.Punch test repeatedly shows: when the hard disk integral punching press is destroyed, cast aluminium disk body in the middle of the hard disk is fragmented into the irregular little aluminium block of sharp corners under the effect of pressure, and the big more cracked aluminium block of pressure is just more little, many more, the fragment of these aluminium under the effect of pressure, from below the disc of aluminum is isolated irregularly distortion (convex-concave, distortion, cavity, tear etc.); Simultaneously, the top cover of hard disk torsional deformation under pressure subsides, and from top disc is destroyed; Wiring board in the hard disk back of the body lid is owing to uneven distributions such as its chip, original papers, and also inhomogeneous to the breakdown pressure of disc under pressure, this has more strengthened the geometric distortion degree of disc; The effect of this immense pressure is equivalent to carry out uneven extension " processing " to containing disc at interior hard disk agglomerate, at this moment disc no longer has been the shape of a slice disk, it is an aluminium scrap sheet, it by powerful punching press in the agglomerate that constitutes by metal, resin, be the random three-dimensional shape in space, if it all is very difficult wanting to isolate from agglomerate whole " disc ", find the magnetic track and the center of circle on it not to have possibility again for the aluminium flake after distortion, the stretching, let alone read information! This pressure destruction degree to hard disc is than the particle of pulverizing the back rule and to be rolled into the destruction degree of corrugated plate of rule higher, and it is safer, thorough that hard disk integral pressure is destroyed the method for classified information.

It also is so that this equipment is used for when CD is destroyed because head can be designed to non-homogeneous stressed shape, " CD " after the compression failure no longer be rule disk (more not having the center of circle can say), be processed into plastic tab by " punching press "! Because the uneven distribution of plastic sheet is even, random variation has all taken place in the distance in distance between session originally and the same session between measuring point, and the plastic tab of this moment does not have " road " and can follow, and classified information can not be read, more can't reduce, CD is thoroughly destroyed.The destroying method of this CD is more favourable for reclaiming plastics.

It is all the more so when this equipment is used for the destruction of semiconductor storage body, semiconductor storage body (as: USB flash disk, CF card, SM card, SD card, memory stick and IC-card etc.) comes stored information by Plastic IC Packages integrated chip on the circuit board, the immense pressure of this destroy device is easy to these Plastic IC Packages integrated chip crushing, its inner pin leads was pressed down when chip was cracked, even the silicon chip of recorded information is all crushed, these information are also cut off difficulty and are read, thus the classified information of thoroughly destroying the semiconductor storage body and being put down in writing.

For solving the problems of the technologies described above, the destroy device of hard disk of the present invention, CD and semiconductor storage body comprises: feed mechanism, pressure are destroyed mechanism, discharging mechanism, power source feeding mechanism, control and safety guard etc. automatically.
