Description
Technical field
The present invention relates to wood processing technique field, specifically a kind of method of timber pickling device impregnated timber.
Background technology
Timber pickling device, is mainly made up of timber pickling tank body, is that a kind of HTHP for being usually used in treating of wood is set
It is standby, it is that untreated timber is put into impregnating autoclave, being passed through a kind of medium for handling timber, (dielectric property is similar to wax, often
It is solid under temperature state, normal atmosphere pressure fusing point is 80 DEG C or so), by this medium thermophilic digestion timber, while high pressure
Medium is allowed to penetrate among timber.Usual operating pressure is more than 1MPa, and temperature is more than 150 DEG C.Under normal operating conditions, in timber tank
Medium can constantly reduce, into timber, so needing to be continuously replenished the medium.
Current timber pickling device, reaches after certain pressure and temperature, is difficult to be always maintained at medium temperature under working condition
Degree is more than desired temperature, and the pump housing used on existing market, it is difficult to meet high flow capacity while meeting high pressure
It is required that, main reason is that, want to meet high pressure, just must constantly pressurize, during continuous pressurization, if outflow
Flow rate of liquid is too fast, can substantially reduce overall pressure again, and the pump housing is in order to keep high pressure high flow rate to increase the pump housing
Power, the increase of this power is often the several times even increase of decades of times, and this requirement to the pump housing will be greatly improved, and mesh
Preceding technology is difficult to really make meeting to require the pump housing of power, therefore, while how keeping timber pickling tank high pressure again
There is the inflow of high flow capacity medium, be always to perplex one of problem of timber pickling processing.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of method of timber pickling device impregnated timber, soak timber
Stain tank keeps having the inflow of high flow capacity medium while high pressure again.
In order to solve the above technical problems, the technical scheme is that：A kind of timber pickling device, including high-temperature pressure storage
Liquid case, force (forcing) pump, HTHP fluid reservoir, pressurization is provided between the high-temperature pressure liquid reserve tank and HTHP fluid reservoir
Heater is provided with pump, the HTHP fluid reservoir, the HTHP fluid reservoir is respectively by entering ceratuba road and returning
Ceratuba road is connected with timber pickling tank, and enters the level height that the level height in ceratuba road is less than go back to ceratuba road, it is described enter ceratuba
Circulating pump is respectively arranged with road and enters at wax stop valve, the opening of described timber pickling tank one end to be provided with retractable sealing
Tank door, be provided with back wax stop valve on described time ceratuba road, and the timber pickling tank is internally provided with electric heating piece, the timber
The upper surface of impregnating autoclave is respectively arranged with safety valve, overfall, bleeding point, pressure gauge, pressure sensor, and temperature sensor is located at
On the side wall of timber pickling tank, the safety valve is connected with overfall by communicating pipe.
The method of above-mentioned timber pickling device impregnated timber, comprises the following steps：
Step 1: heating medium
Medium in HTHP fluid reservoir and high-temperature pressure liquid reserve tank is heated to liquid condition, it would be desirable to the wood of processing
Material, which loads after timber pickling tank, closes hermetically sealed can door；
Step 2: vacuumizing and adding medium
Timber pickling tank is evacuated to -0.08~-0.09MPa using aspirating hole, force (forcing) pump and circulating pump work simultaneously,
The liquid medium of HTHP fluid reservoir will be continuously added timber pickling tank by entering ceratuba road, until liquid medium is all filled out
Full timber pickling tank, force (forcing) pump is constantly by the liquid medium injection HTHP liquid storage in high-temperature pressure liquid reserve tank in the process
In tank, the liquid medium of HTHP fluid reservoir outflow is filled up；
Step 3: circulation dipping
1.6MPa is forced into, is heated up to after 150 DEG C, current pressure and temperature is kept, a period of time is then placed to timber
Impregnation process is carried out, when temperature drop is to less than 140 DEG C DEG C in temperature sensor senses to timber pickling tank, HTHP storage
Heater in flow container is started working, while circulating pump task, the liquid medium that will be heated in HTHP fluid reservoir again
The liquid medium being pumped into by circulation in timber pickling tank, timber pickling tank passes through go back to ceratuba road and is back to HTHP storage again
Flow container is heated, and realizes circulation dipping.
By adopting the above-described technical solution, under working condition, the medium in timber pickling tank constantly can be penetrated into timber,
The force (forcing) pump material that supplement is penetrated into timber while pressurization is realized, to ensure in HTHP fluid reservoir and timber pickling tank
Medium be always full.Using the form of double tank double pumps, force (forcing) pump high pressure low discharge meets disappearing for medium under working condition
Consumption and required operating pressure.Circulating pump high flow low pressure, circulating pump complete HTHP fluid reservoir and timber pickling tank it
Between medium circulation, front and rear pressure differential is zero, make timber pickling tank keep high pressure while have again high flow capacity medium flow into, take out
Vacuum is to extract the air in tank out, preferably allow liquid medium to enter in tank body.
Brief description of the drawings

With the leaching of the bottom of force (forcing) pump 2 in the hot water, and on all pipelines it is wound with heater 4.
The method of above-mentioned timber pickling device impregnated timber, comprises the following steps：
Step 1: heating medium
Medium in HTHP fluid reservoir 3 and high-temperature pressure liquid reserve tank 1 is heated to liquid condition, it would be desirable to processing
Timber, which loads after timber pickling tank 8, closes hermetically sealed can door 18；
Step 2: vacuumizing and adding medium
Force (forcing) pump 2 and circulating pump 6 work simultaneously, by entering ceratuba road 15 by by the liquid medium of HTHP fluid reservoir 3
Timber pickling tank 8 is continuously added, until liquid medium completely fills out timber pickling tank 8, force (forcing) pump 2 is constantly by height in the process
In liquid medium injection HTHP fluid reservoir 3 in normal temperature and pressure liquid reserve tank 1, the liquid of the outflow of HTHP fluid reservoir 3 is filled up
Medium；
Step 3: circulation dipping
1.6MPa is forced into, is heated up to after 150 DEG C, current pressure and temperature is kept, a period of time is then placed to timber
Impregnation process is carried out, when temperature sensor 14 senses that temperature drop is to less than 140 DEG C DEG C in timber pickling tank 8, high temperature is high
Heater 4 in pressure fluid reservoir 3 is started working, while the task again of circulating pump 6, by what is heated in HTHP fluid reservoir 3
The liquid medium that liquid medium is sent into timber pickling tank 8, timber pickling tank 8 by circulating pump 6 passes through go back to ceratuba road 16 times again
Flow to HTHP fluid reservoir 3 to heat, realize circulation dipping.
Heater 4 is wound on all pipelines, circulating pump 6 and the bottom of force (forcing) pump 2 are immersed among hot water, so design is
Because it is that may remain medium in pipeline to be stopped, pipeline can be blocked after air-setting, the pump housing is carried due to being not suitable for
Heater, so by leaching in the hot water, preventing ambient temperature too low, liquid medium solidification produces destruction to the pump housing.
Schematical embodiment of the invention is the foregoing is only, the scope of the present invention is not limited to.It is any
Those skilled in the art, made equivalent variations and modification on the premise of the design of the present invention and principle is not departed from,
The scope of protection of the invention should be belonged to.
