Advantageous effect：
The utility model vacuum pressure impregnation can not only make modifying agent enter the deeper part of material in the shorter time
Position, and the big minor adjustment of pressure and vacuum can be utilized to enter depth and inlet, the difference for adapting to material character variation is wanted
It asks, improves treatment effeciency and control cost.
Description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description.
Fig. 1 is the electrical block diagram of the utility model.
Specific implementation mode
According to Fig. 1, the utility model includes：Feeding funnel 1, feed appliance 2, mill 3, boiling vessel 4, explosive cartridge 5, explosion
Valve 6, fiber receiver 7, air inlet 8, muffler 9, boiling vessel entrance 10.
Vacuum pressure impregnation system, the system include：It is pressure impregnation tank 1, cyclic water tank 2, medical solution pool 3, centrifugal pump 4, true
Sky pump 5, force (forcing) pump 6, liquid sucking-discharging valve 7, partial pressure pump 8, pressure gauge 9, vacuum meter 10, forcing press 11；
Cyclic water tank 2 is fixedly connected with centrifugal pump 4, vacuum pump 5 respectively, and centrifugal pump 4 is connected with empty pump, centrifugal pump 4 with it is true
Empty table 10 is fixedly connected, and vacuum meter 10 is connect with pressure gauge 9, and pressure gauge 9 is fixedly connected with pressure impregnation tank 1, pressure gauge 9 and pressure
Power machine 11 is fixedly connected, and partial pressure pump 8 is fixedly connected with pressure impregnation tank 1, and partial pressure pump 8 is fixedly connected with medical solution pool 3；Pressure impregnation
Tank 1 is fixedly connected with force (forcing) pump 6, and force (forcing) pump 6 is fixedly connected with medical solution pool 3, pressure impregnation tank（1）By liquid sucking-discharging valve 7 with
Medical solution pool 3 is fixedly connected.
Pressure impregnation tank 1 is packed into pending timber.
The pressure that vacuum pressure impregnation system applies is hydraulic pressure.
The pressure that vacuum pressure impregnation system applies is air pressure.
It is equipped in medical solution pool 3 into improved chemical solution.
Operation principle：
1, being placed in timber can bear in the process tank of pressure, cause certain negative pressure with vacuum pump first, to remove
Gas in small material lumen, is re-introduced into improved chemical solution, then applies certain pressure into process tank by pressue device
Power makes in modifier solution pressure people's wood cell.
2, make to be full of modifier solution in wood cell, timber is made to remain with the maximum amount of modifying agent.This method condition
Compare harsh, can reach maximum modification agent and inhale dose and penetration depth.Its operating process can be divided into five stages.
1) the initial vacuum stage
Timber is put in people's pressure impregnation tank, is vacuumized impregnating autoclave with vacuum pump, and kept for certain time, to take out
Go out the air in wood cell chamber so that timber is easy the agent dipping that is modified, and reduces the modifying agent in release
Recoil comes out, and retains more modifying agent in wood.
2) add the modifying agent stage
In the case where not closing vacuum pump, that is, under conditions of keeping original vacuum degree, add people's modifier solution.
3) pressure period
After modifying agent fills it up with pressure impregnation tank, vacuum pump is closed, after eliminating vacuum, application pressure (hydraulic pressure can be used,
Air pressure can be used), reach and keep a period of time after required pressure, until required modified dosage dearly by
It is pressed into timber, or refuses until after absorbing modifier solution to timber.When pressure period end of a period, pressure release, by
In the expansion for a small amount of air being compressed in timber, the pressure period by the modifier solution that timber absorbs have part this
Recoil comes out in Shi Huicong timber, returns in pressure impregnation tank.
4) blowdown period
After pressure relief, using the gravity of modifier solution, or with positive displacement pump, by pressure impregnation tank towel to being modified
In agent solution storage tank.
5) vacuum stages afterwards
The vacuum degree of vacuum stages is as the stage of initial vacuum or weaker afterwards, keeps, then discharging vacuum, put
The improved chemical solution for going out rear vacuum stages extraction, takes out processed timber.
3, amount of modifier is reduced in the case where ensureing certain penetrance.Such effect in order to obtain, with preceding air
Initial vacuum in pressure substitution full-cell process so that there is more fire retardant to recoil out in rear vacuum stages
The above is only the preferred embodiment of the utility model only, is not intended to limit the protection model of the utility model
It encloses.Any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention, are all contained in this reality
With in novel protection domain.
