Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is further described:
Referring to Fig. 1, the first embodiment of one micro-blasting device inside lumber of the present invention, including high pressure Cylinder A, unload pressure cylinder B, piston cylinder C, auxiliary piston cylinder D.
High pressure cylinder A needs the timber of micro-explosion for accommodating, and cylinder body is provided with gases at high pressure import 2, two ends It is respectively charging aperture and relief port;One end of charging aperture is provided with quick operating valve 1, puts into high pressure cylinder A at timber Rear quick operating valve 1 sealed feed inlet, this quick operating valve 1 uses the door that can quickly open and close sealing of routine i.e. Can;One end of relief port is provided with cover plate 3 that is salable and that open this relief port, when cover plate 3 and quick operating valve 1 are close After sealing this high pressure cylinder A two ends, form airtight high pressure chest in high pressure cylinder A, be placed in the timber in high pressure cylinder A It is immersed in gases at high pressure;After timber soaks certain time, when needing to carry out explosion, quickly open cover plate 3, the gas moment in high pressure cylinder A drops to normal pressure, and in the tissue of wood internal, cell and pitpair Have the structures such as torus can not rapid decrease and be in high pressure conditions, such inside and outside differential pressure is big and forms explosion Effect.Seal against each other between cover plate 3 and relief port on the face contacted and be fixed with sealing gasket;Certainly, cover plate 3 Can be inclined-plane with sealing against each other the face contacted between relief port, improve sealing effectiveness.
Unloading pressure cylinder B to be connected on the cylinder body of high pressure cylinder A, cover plate 3 is slidably disposed on this and unloads in pressure cylinder B, Unload the barrel of pressure cylinder B to close on the position of relief port and offer steam vent 4, when relief port opened by cover plate 3, high Gases at high pressure in cylinder pressure A are discharged to the external world from this steam vent 4.
Unload pressure cylinder B tail end and connect piston cylinder C, the piston rod of piston cylinder C stretch in unloading pressure cylinder 2 and with cover plate 3 Fixing connection;The afterbody of piston cylinder C is also associated with auxiliary piston cylinder D, on the afterbody end cap 8 of this piston cylinder C Offering auxiliary exhaust mouth, the piston 10 of auxiliary piston cylinder D can support and seal this auxiliary exhaust mouth, piston 10 with the sealing of afterbody end cap 8;Air inlet 11 and the gas outlet 13 of auxiliary piston cylinder D are opened in auxiliary piston On cylinder D aft end lid;The piston rod 12 of piston cylinder C slidably extends through auxiliary piston cylinder D, this auxiliary piston The piston 10 of cylinder D slidably and is hermetically set on this piston rod 12.Certainly, this auxiliary piston cylinder D Piston 10 can also hermetically be fixed on this piston rod.
In order to accelerate the release speed in the right chamber of piston cylinder C, the barrel at auxiliary piston cylinder D closes on described piston The position of cylinder C offers auxiliary exhaust ports 9.
Referring to Fig. 1 to Fig. 3, the work process of the present invention illustrates:
As shown in Figure 1: the timber needing micro-explosion is put into high pressure cylinder A, close quick operating valve 1, seal Timber import, closes the gas outlet 13 of auxiliary piston cylinder D, opens air inlet 11 and input gases at high pressure, auxiliary The piston 10 of piston cylinder D is moved to the left the auxiliary exhaust mouth on the afterbody end cap 8 of closed piston cylinder C, piston cylinder The air inlet 7 of C is passed through gases at high pressure, promotes piston 6 to be moved to the left, and then promotes cover plate 3 by piston rod It is moved to the left, seals the relief port of high pressure cylinder A, then open the air inlet 2 of high pressure cylinder A in high pressure cylinder A It is filled with gases at high pressure, until the pressure that technique needs.
When timber is soaked certain time by gases at high pressure in high pressure cylinder A, make wood internal air pressure reach with After high-pressure gas pressure balance, as shown in Figures 2 and 3, the air inlet 2 of high pressure cylinder A, piston cylinder C are closed Air inlet 7, the air inlet 11 of auxiliary piston cylinder D, open gas outlet 13 and discharge the high pressure in auxiliary piston cylinder D Gas, the piston 10 of auxiliary piston cylinder D moves right, and meanwhile, the air inlet 5 of piston cylinder C is passed through high pressure gas Body, the cylinder inner high voltage gas of piston cylinder C right-hand member auxiliary exhaust mouth from the afterbody end cap 8 of piston cylinder C, auxiliary Exhaust-assisting hole 9 is discharged, pressure rapid decrease, promotes piston 6 to move right, and then is promoted by piston rod Cover plate 3 moves right, and the relief port of high pressure cylinder A is quickly opened, and the gases at high pressure in high pressure cylinder A are quickly from height The relief port of cylinder pressure A, the steam vent 4 unloaded on the barrel of pressure cylinder B are discharged to the external world, the timber in high pressure cylinder A The process of micro-explosion is completed under the effect of inside and outside differential pressure.
Referring to Fig. 4 and Fig. 5, one micro-blasting device inside lumber the second embodiment of the present invention, with upper Stating the first embodiment to compare, the second embodiment includes high pressure cylinder A, unloads pressure cylinder B, piston cylinder C, no It is fixed with unloading the end that pressure cylinder B is connected including the auxiliary piston cylinder D, piston cylinder C in the first embodiment, Being fixed with iron block 61 on the piston 6 of piston cylinder C, air inlet 11 and the gas outlet 12 of piston cylinder C are opened in piston On the aft end lid of cylinder C, the piston rod 12 of piston cylinder C slidably extends through the afterbody end cap of piston cylinder C.When When pressurizeing high pressure cylinder A, electric magnet 5 energising produces electromagnetic force, is held by the iron block 61 on piston 6, Piston rod 12 is promoted by piston 6 and is moved to the left, and then promotes cover plate 3 to be moved to the left by piston rod, close The relief port of envelope high pressure cylinder A, closes A chamber, and meanwhile, the gas outlet 12 of piston cylinder C is closed, air inlet 11 It is passed through a certain amount of compressed air, in case as buffering during aerofluxus.When high pressure cylinder A is carried out release, electricity Magnet 5 power-off, electromagnetic force disappears, and cover plate 3 is promoted to the right, passes through piston by the gases at high pressure in high pressure cylinder A Bar 12 promotes piston 6 to move right, the gases at high pressure in high pressure cylinder A quickly from the relief port of high pressure cylinder A, unload Steam vent 4 on the barrel of pressure cylinder B is discharged to the external world, and the timber in high pressure cylinder A is under the effect of inside and outside differential pressure Completing the process of micro-explosion, meanwhile, the air inlet 11 of piston cylinder C is closed, and gas outlet 12 is opened, piston 6 Quickly moving right, the air in piston cylinder C is compressed, and plays cushioning effect, can be given vent to anger by regulation The size of mouth 12 reaches to regulate the effect of buffer size.
