It is provided with medical solution pool into improved chemical solution.
Beneficial effect：
Vacuum pressure impregnation of the present invention can not only make modifying agent enter the deep part of material, Er Qieke in the shorter time
Depth and inlet are entered with the big minor adjustment using pressure and vacuum, the different of material character change is adapted to and requires, at raising
Manage efficiency and control cost.
Brief description of the drawings
The present invention is further illustrated with reference to the accompanying drawings and detailed description.
Fig. 1 is the electrical block diagram of the present invention.
Embodiment
According to Fig. 1, the present invention includes：Feeding funnel 1, feed appliance 2, mill 3, boiling vessel 4, explosive cartridge 5, explosive 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
Empty 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, vavuum pump 5 respectively, and centrifugal pump 4 is connected with empty pump, centrifugal pump 4 and vacuum meter
10 are fixedly connected, and vacuum meter 10 is connected with pressure gauge 9, and pressure gauge 9 is fixedly connected with pressure impregnation tank 1, pressure gauge 9 and forcing press
11 are 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
It is fixedly connected with force (forcing) pump 6, force (forcing) pump 6 is fixedly connected with medical solution pool 3, pressure impregnation tank（1）Pass through liquid sucking-discharging valve 7 and decoction
Pond 3 is fixedly connected.
Pressure impregnation tank 1 loads 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 provided with medical solution pool 3 into improved chemical solution.
Operation principle：
1st, being placed in timber to bear in the process tank of pressure, cause certain negative pressure with vavuum pump first, to remove small material
Gas in lumen, improved chemical solution is re-introduced into, then applies certain pressure into process tank by pressue device, make
In modifier solution pressure people's wood cell.
2nd, make to be full of modifier solution in wood cell, timber is remained 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, vacuumized impregnating autoclave with vavuum pump, and is kept for certain time, it is thin to extract timber out
Air in cell so that timber be easily modified agent dipping, and reduce in release modifying agent recoil out, retain it is more
Modifying agent in wood.
2) the modifying agent stage is added
In the case where not closing vavuum pump, that is, under conditions of keeping original vacuum, add people's modifier solution.
3) pressure period
After modifying agent fills it up with pressure impregnation tank, vavuum pump is closed, after eliminating vacuum, application pressure (hydraulic pressure can be used, can also
With air pressure), kept for a period of time after reaching required pressure, until required modification dosage has been pressed into dearly
In timber, or untill timber is refused to absorb after modifier solution.When pressure period end of a period, pressure release, due to quilt
The expansion of a small amount of air of compression in wood, there is part now can by the modifier solution that timber absorbs in the pressure period
Recoil and come out from timber, return in pressure impregnation tank.
4) blowdown period
It is using the Action of Gravity Field of modifier solution, or with positive displacement pump, pressure impregnation tank towel is molten to modifying agent after pressure relief
In liquid storage tank.
5) vacuum stages afterwards
The vacuum of vacuum stages is as the stage of initial vacuum afterwards, or weaker, keeps, vacuum then being discharged, after releasing
The improved chemical solution that vacuum stages are extracted out, takes out the timber through processing.
3rd, amount of modifier is reduced in the case where ensureing certain penetrance.In order to obtain such effect, 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 foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the scope of the present invention.It is all in this hair
Any modification, equivalent substitution and improvements made within bright spirit and principle etc., are all contained in protection scope of the present invention.
