Description
Technical field
The utility model relate to a kind of ceramic tile demolition reduction system based on ultrasonic activation.
Background technology
China human mortality quantity is occupied first place in the world, and resident room is in great demand, and nowadays room rate remains high, many people
Second-hand house can be bought as starter home, or finishing before is unsatisfied with, this is accomplished by carrying out house secondary decoration, and two
Ceramic tile dismounting in secondary fitment process, which is one, wastes time and energy and costly process.If ceramic tile can be torn open completely and quickly
Remove, if the ceramic tile shape removed is complete, use time is not long, then can continue as using during other home improvements,
The waste that certain expense reduces material can be saved.
At this stage, the method for more efficient hand-crushed ceramic tile is to carry out broken porcelain using electric impact drill to handle specific method
Be, first with electric drill ceramic tile center bore a sky so that ceramic tile integrality is destroyed, then recycle electric impact drill or
Steel is carved and tapped so that ceramic tile comes off on metope.The method of manual demolition ceramic tile is arduously time-consuming, must if thinking quick dismounting
Ceramic tile must be destroyed, and it is possible to damage wall；If removing completely is want ceramic tile, when needing to spend substantial amounts of
Between and expense.
Traditional mechanical means is the principle using hammering, and this method noise is big, wastes time and energy, and due to hammer force
Degree is uncertain, and the surface of wall finally obtained is uneven, and wants using traditional mechanical means to realize coming off for ceramic tile
Ceramic tile must be destroyed, be unfavorable for secondary utilization.Ultrasonic wave is the sound wave that a kind of frequency is higher than 20000 hertz, its directionality
Good, penetration capacity is strong, it is easy to obtain the acoustic energy relatively concentrated, available for ranging, test the speed, clean, weld, rubble, sterilizing etc..
In medical science, military affairs, industry, agriculturally there are many applications.Ultrasonic wave is gained the name because of the upper limit of hearing that its lower-frequency limit is more than people.
Theoretical research shows that, the energy of an object vibration is directly proportional to vibration frequency in amplitude under the same conditions, and ultrasonic wave is being situated between
When being propagated in matter, the frequency of medium particle vibration is very high, thus energy is very big.The broken road machine of resonance on current market is exactly profit
The broken road of resonance is carried out with the principle of vibration transmission energy.
The broken ceramic tile mechanism commentary more advanced through retrieving is as follows：
A kind of floor ceramic tile disintegrating machine of on July 26th, 2013 Shen Ke plumage applications.Patent No.：CN203531336U.Should
Device belongs to the technical field of disintegrating machine, and in particular to a kind of floor ceramic tile disintegrating machine, and it includes motor, iron hammer curved surface circle

Pneumatic pick agent structure is from top to bottom successively by pick handle, pneumatic pick.The device advantage is simple, economy.Have the disadvantage mechanical breaking ceramic tile
Wall and metope water-proofing treatment can be damaged, is lost more than gain.
So far, most of furring tile is removed also without that can meet the equipment that ceramic tile is complete and quickly removes in the world
Still by being accomplished manually.It is mechanical impact that the existing ceramic tile of in the market, which removes equipment, and not only noise is big, and can be to ceramic tile
Certain destruction is caused with metope.Have so making ceramic tile quickly intactly remove and not damage metope during secondary decoration
It is significant, need a kind of furring tile breaker badly.The subject matter present in ceramic tile breaker is can not be to wall
Furring tile realizes and effectively crushed that low to different operating environment adaptedness, whole work efficiency is low.
The method of traditional hand-crushed wall is arduously time-consuming, if thinking quick dismounting, must destroy ceramic tile, and
It is possible to damage wall；If wanting ceramic tile removing completely, require a great deal of time and expense；Floor ceramic tile is broken
Broken machine iron hammer pumps, and hammering is larger to damage of wall, and is not particularly suited for furring tile；Ultrasonic disruption one
Body machine is used for the preparation of tydrophilization and nano material, does not apply to the broken of ceramic tile class hard brittle material, overall work effect
Rate is low；The electronic pneumatic pick mechanical breaking ceramic tile of jack column can damage wall and metope water-proofing treatment, lose more than gain.It is several above
Method all uses mechanical shock crush method, it is desirable to remove ceramic tile from wall, it is necessary to first ceramic tile is destroyed, is unfavorable for ceramic tile
It is secondary to utilize, also, because hammering depth is not known, the metope after break process is difficult to ensure that concordantly, ceramic tile after being unfavorable for
Secondary pave.
