Description

A kind of wood vacuum pressure impregnating equipment

Technical field

The utility model is related to a kind of wood vacuum pressure impregnating equipment.

Background technology

Timber is widely used in the place closely bound up with people's life as a kind of renewable environmentally friendly material, such as Building, furniture etc., its easy processing, carrying capacity of environment are small, be steel, cement it is incomparable, still, timber as one kind it is organic Natural macromolecular material, exist it is inflammable, it is perishable, easily damage by worms, the problem of size is unstable, physical and mechanical property energy consumption is low, this A little problems make the application of timber be very limited, in order to overcome the disadvantages mentioned above of timber, and people, which think to impregnate in timber, changes it Functional improvement reagent of property, for example, fire retardant, preservative, mould inhibitor and changing resin of its mechanical property etc..

It is general to select vacuum pressure impregnation tank during timber resin pickup, it is general from true during timber resin pickup in dipping Pneumatics power impregnating autoclave, in dipping, maceration extract is inactive state, and maceration extract can be adsorbed first in wood surface, hinders maceration extract to enter Enter wood internal, cause dip time long, in addition, the wood surface for preparing dipping is usually roughing sheet material, wood surface meeting There are many fiber fines（Wolline）, fiber fines can be also adsorbed in wood surface, can also hinder the speed that glue enters wood internal Degree.

Utility model content

Utility model purpose：The purpose of this utility model is that there is provided a kind of wood in order to solve above the deficiencies in the prior art Material vacuum pressure impregnating equipment, dip time is short.

Technical scheme：A kind of wood vacuum pressure impregnating equipment described in the utility model, including tank body, described tank body The interior inner cylinder for being provided centrally with upper and lower opening, is surrounded with multiple timber brackets, institute between inner tank theca and inner tank wall The timber bracket stated includes rectangle underframe, is arranged at the support column at rectangle underframe corner and is arranged at intervals above rectangle underframe Multiple semicircular arcs separation frame, two mouldings relative with rectangle underframe are connected respectively for the two ends of described separation frame, separate The space formed between frame is timber accommodating chamber, and described tank body top is provided with the escape pipe communicated with impregnating autoclave, The escape pipe is connected with vacuum pumping pump, and the bottom of tank body is provided with the air inlet pipe for stretching into inner cylinder bottom, the air inlet pipe and booster pump It is connected.

Preferably, the spacing between described separation frame is slightly larger than the thickness of timber, and the radius of separation frame is timber height More than 1/2, the width of rectangle underframe is less than timber width.

Preferably, described inner cylinder lower diameter gradually increases.

Preferably, described escape pipe is connected with gas distributor, and described gas distributor includes being connected with escape pipe Logical point of gas bag and the branch pipe arranged and be connected with point gas bag in divergent shape along point gas bag circumference, described branch pipe top along The axial spaced set of branch pipe has multiple gas outlets.

Beneficial effect：When carrying out pressure process to impregnating autoclave, compressed gas is gone out by booster pump to air inlet pipe, is driven interior Cylinder maceration extract is moved upwards, between inner tank theca and inner tank wall, under gravity, forms membranaceous along wood plank Decline, enter inner cylinder in tank base, circulate, accelerate maceration extract to enter wood internal, shorten dip time so that dipping Property is consistent in timber table afterwards.

Embodiment

In order to deepen to understand of the present utility model, further is made to the utility model below in conjunction with embodiment and accompanying drawing It is described in detail, the embodiment is only used for explaining the utility model, does not constitute the restriction to the utility model protection domain.

Referring to Fig. 1 and Fig. 2, a kind of wood vacuum pressure impregnating equipment, including tank body 1, the center in described tank body is set The inner cylinder 2 of upper and lower opening is equipped with, described inner cylinder lower diameter gradually increases, is surround between inner tank theca and inner tank wall Multiple timber brackets are provided with, described timber bracket includes rectangle underframe 3, is arranged at the support column 4 at rectangle underframe corner With the separation frame 5 for the multiple semicircular arcs being arranged at intervals above rectangle underframe, the two ends of described separation frame 5 respectively with rectangle Two relative mouldings 3 of underframe are connected, and the space formed between separation frame 5 is timber accommodating chamber, in order to preferably by timber Plate is placed in vertical state, and the spacing between described separation frame 5 is slightly larger than the thickness of timber, and the radius of separation frame 5 is high for timber More than the 1/2 of degree, the width of rectangle underframe 3 is less than timber width.

Described tank body top is provided with the escape pipe 6 communicated with impregnating autoclave, and the escape pipe is connected with vacuum pumping pump, tank The bottom of body is provided with the air inlet pipe 7 for stretching into inner cylinder bottom, and the air inlet pipe is connected with booster pump.Described escape pipe and gas point Cloth device is connected, and described gas distributor includes point gas bag 8 being connected with escape pipe and is in divergent shape cloth along point gas bag circumference The branch pipe 9 put and be connected with point gas bag, there are multiple outlets on the described top of branch pipe 9 along the axial spaced set of branch pipe Mouthful.

Wood plank 10 is vertically placed between the separation frame 5 of plank bracket, starts vacuum pumping pump, to the gas in impregnating autoclave Body carries out vacuumize process, reaches after certain vacuum, then adds Wood modifier to impregnating autoclave, when in impregnating autoclave There is not after timber for Wood modifier, opens booster pump, and compressed gas is gone out by booster pump to air inlet pipe, drives inner cylinder maceration extract Motion, between the outer wall of inner cylinder 2 and the inwall of tank body 1, under gravity, membranaceous decline is formed along wood plank upwards, Enter inner cylinder 2 in tank base, form circulation, after pressure reaches predetermined pressure, after pressurize 1-2h, complete dipping.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
