Abstract
An autoclave device producing the light xylolite fiber board belongs to the man-made plate device field. The device is a confined frame structure and comprises a frame cover and a frame body. The frame body portion is provided with a water inlet, a water outlet, a steam outlet passage and a steam pressure meter to control the steam generation and discharge. The frame cover and the frame body of the steam generating device are respectively disposed on the upper compressing board and the lower compressing board of the common man-made plate heat compressor. Along with the forcing and closing of the compressor, the frame cover and the frame body are completely closed under the effect of pressure to form a confined space, the water filled in the frame body will be heated and vaporize to generate steam, thereby forming a steam pressure in the confined space to achieve the purpose of autoclave to the product. The compressor can not only achieves the autoclave of the timber and non-timber composite material under the confined steam pressure with short hot compression cycle, product property index satisfying or exceeding the similar product property index from home and abroad, and reduced water steam loss in the autoclave process and facility investment.
Description
Technical field
The utility model relates to a kind of steaming and presses press, and the utility model relates to a kind of wood-based plate manufacturing press that steams pressure device that has more precisely, belongs to field of mechanical technique.
Background technology
In recent years, wood-based panel industry is in order to shorten medium density fibre board (MDF) and particieboard effectively both at home and abroad, especially the slab production efficiency that thickness is bigger, guarantee product quality, reduce energy consumption, reducing cost, researched and developed following new heat pressing process, is exactly wherein a kind of hot pressing new technology such as steam injection pressing.Its principle of steam injection pressing technology is in hot pressing high-temperature steam to be annotated in people's slab, and the slab internal temperature is increased on the solidification temperature of glue fast, quickens the curing of glue, shortens pressing cycle.It can effectively improve the production efficiency of medium density fibre board (MDF) and particieboard, guarantees product yield, reduces energy consumption, reduces cost, and has broad application prospects in MDF and particieboard production.Existing in the world this technology extrusion chipboard, directional structure board, medium density fibre board (MDF) and some nonwoodbased panels of utilizing.
The hot press of utilization steam spraying technology has more special structure, and promptly being drilled with diameter on the clamp surface of hot press is about 3mm and the steam jetting hole of arranging according to certain rules.For preventing that fiber fines and wood shavings from stopping up steam jetting hole, be lined with anticorrosion, anti-oxidation mesh pad on the pressing plate, the limit portion rubber packing of gauze pad is to prevent steam leakage.Simultaneously, also need steam generator device, against vacuum steam injection pressing technology also needs vacuum treatment device etc.
Summary of the invention
For some wooden and non-composite wooden materials, such as lightweight magnesia wood wool board, all be that the cycle of moulding is long by the maintenance moulding of colding pressing usually, production efficiency low (, also needing long pressurize curing period) even hot-forming.And against vacuum steam injection pressing technology although can have the effect of heating rapidly, can not play the steam press maintenance effect.The utility model provides a kind of steaming to press press, this press not only can be suppressed wooden and non-composite wooden material under airtight steam pressure, and can play steam press maintenance pressing cycle is shortened, the performance indications of product can meet and exceed the performance indications of similar products at home and abroad; And equipment investment is little.
The utility model is to realize by following technical scheme:
The wood-based plate manufacturing is pressed press with steaming, and comprises frame lid, steam pressure gauge, framework, water outlet/row's steam channel and intake tunnel; It is characterized in that frame cover and frame body is installed in the closed-in construction that forms sealing on the last lower platen of common man-made board hot-pressing machine respectively, described steam pressure gauge, water outlet/row steam channel, intake tunnel are positioned on the framework limit, and frame covers and is positioned on the framework.
This steam generation device is made up of two parts: frame cover and frame body for the closed-in construction of sealing.When two parts are closed, form the frame space of a sealing, this space maximum height is 30mm.Frame is arranged with into water, water outlet, steam passing away and steam pressure gauge, controls the generation and the discharge of steam.
The frame cover and frame body of steam generation device is installed in respectively on the last lower platen of common man-made board hot-pressing machine, during the lower platen heat temperature raising, will carries out transmission of heat by contact on the press, heat to together more than 100 ℃ with frame cover and frame body.An amount of water is put into framework by intake tunnel, and the product and the finger gauge of the moulding of the assembly of precompressed are simultaneously put into framework together.Pressurization closure along with press, product will be compressed into the height of finger gauge, frame cover and frame body is closed fully under pressure, form an enclosure space, the water that adds in the framework will be subjected to thermal evaporation, produce steam, thereby in the space of sealing, form certain vapour pressure, reach the purpose of product being steamed pressure.After treating that the steaming pressure is finished, open the steam passing away of framework, exhaust steam and remaining water, the product that suppresses is taken out in release.
The beneficial effects of the utility model are, press not only can be suppressed wooden and non-composite wooden material under airtight steam pressure, and pressing cycle is short, and the performance indications of product can meet and exceed the performance indications of similar products at home and abroad; And the steam loss is few in the steaming pressure process, and equipment investment is little.
