Definitions
- the present invention consists in a thermal insulation board made of ground paper in a mixture with natural fibers such as jute or the like.
- a thermal insulation board is e.g. described in the unpublished German patent application P 35 45 00.
- thermal insulation boards have at most an insignificant amount of synthetic chemicals, they are therefore particularly environmentally friendly and meet modern building biological requirements.
- the present invention therefore has the task of improving such thermal insulation boards, in particular to increase their mechanical strength, to incorporate the fibers in a more durable manner and to create a method and an apparatus therefor, with the aid of which such plates can be produced.
- the thermal insulation board according to the invention is obtained from a mixture of shredded flakes with an edge length of 1 to 5 mm and with decay-inhibiting additives, such as preferably borates, pretreated newspaper or the like, paper free of surface coatings or fillers and natural fibers, preferably an edge length of five up to one hundred and glues and / or reaction aids, preferably of vegetable origin. It has surprisingly been found through tests that the edge length and the quality of the end product
- the form of the paper used has a decisive influence.
- the nature of the natural fibers to be used is largely uncritical with regard to their nature, in particular jute, sisal, cotton, coconut, flax, those made from recycling or waste material from spinning mills or processed material made from straw or wood or animal hair, such as preferably wool, preferably one Length from 5 to 100 mm.
- Balsam resins such as Kolophoniu starch or lignin glue, rubber or also road cement, gypsum aluminum sulfate and water glass are preferably used as glues and reaction aids.
- the plates can be produced in such a way that the substances are mixed and loosened, placed in a mold, compressed to the desired density and treated with hot air and / or superheated steam and dried.
- the lignin components contained in the paper are activated and used as binders.
- a particularly effective method according to the invention consists in first premixing paper flakes and fibers, blowing the mixture into a mixing vessel and glue or glue and reaction helix, optionally in the form of an aqueous solution, in countercurrent thereafter, loosening the mixture, in a free case into one Formation station brings and compressed and then treated with hot air or hot air and steam and dried.
- the glues and optionally reaction aids can be injected in powder form, in melted form or as an aqueous solution into the flock and fiber stream and essentially settle on the surfaces of the particles.
- the desired alignment of the fibers and the interlocking or filing of the fibers and flakes is achieved by compacting to plate form, which improve the bond and reduce the need for glue.
- the compacted mass is then treated with hot air or hot air and steam, causing the glue components to flow and then set.
- the loosening and separation of the components before they are introduced into the mold is of major importance. It is therefore further proposed to collect (continuously) the mixture of components produced by countercurrent in a container provided with a loosening mixing element, to discharge it into a chute with the aid of a lock, preferably a cellular wheel lock, and to mix the mixture there again and to loosen up.
- a lock preferably a cellular wheel lock
- the "setting" of the plates takes place under mechanical pressure, passing hot steam or hot air or both, depending on the moisture present and required for the activation of the glues used, through the pressed material under excess pressure and then drying, which e.g. can be done by passing dry air, which can also be sucked through to generate a negative pressure and to accelerate evaporation.
- the process can be varied during filling such that different mixtures are produced in separate mixing devices and these are successively layered on top of one another and then pressed.
- the outer layer can have higher proportions of glue and paper in order to make them smoother or to cover them with the aid of the glue, or, depending on the application, can also contain longer or shorter fiber proportions.
- it is proposed to put the material trickling out of the chute onto a (perforated) conveyor belt, to which a perforated belt (top belt) running at the top is assigned the plate thickness is reduced and runs into the hot steam and / or hot air supply and the drying station.
- the product to be compacted also be guided laterally, for example by its own belts.
- the device according to the invention consists of a cyclone with an upper tangential feed of the fiber / flake mixture and opposite counter-current input of the glue components.
- the mixture rotates peripherally and reaches the bottom of the cyclone where it is collected and monitored by a level indicator. Filter bags are provided on the top for dust removal.
- Rotating comb tine shafts are arranged in the collecting area, underneath there is a rotary valve which doses the material to another mixing element, whereby it can be used if necessary. Below the latter mixing element there is a chute and below this the filling station, and stripping shafts can be provided at the outlet.
- the cyclone 1 has two mutually directed, approximately tangential material inputs, the feed 2 for the premix of paper flakes and natural fibers.
- This premix contains the essential substances, ie in addition to the fibers and paper flock, for example also the putrefactive substances which can be added to the paper during grinding.
- the pressure nozzle 3 With the help of the pressure nozzle 3, the lei is blown into the rotating mixture in powder form or as a melt or in aqueous solution.
- the " storage container 4 with mixer 5 and the dosing container 6 with screw discharge 7 are used to produce the glue.
- the screw discharge is followed by a pressure sprayer 8, which opens into the pressure nozzle 3.
- the material is preferably fed in at low air, for which purpose Devices exist.
- the excess pressure generated by the material input in the interior of the cyclone 1 serves at the same time for dedusting by the filter bags 9 at the top of the cyclone 1.
- the cyclone is equipped with a fill level control 11, which throttles the material supply before being overloaded.
- Mixing elements in the form of comb tine shafts 10 are arranged on the bottom of the cyclone 1, which homogenize the material and prevent premature setting of the glue by constant movement.
- a lock preferably a pin wheel lock 12, which doses the material into the chute 13.
- Evaporation 14 can be provided below the cellular wheel sluice, which serves to pre-swell and stretch the fibers.
- This chute 13 is preferably designed to expand downward in order to prevent caking of glue components when the addition is dissolved or melted.
- a fill level control 15 and underneath it the molding station, which is designed here as a plurality of molding boxes 16 open at the top. The material flows into these boxes 16 in a completely loosened state.
- the boxes 16 are slidably mounted. After a box has been filled, it arrives at a press 17, which compresses the loose bed to the desired density.
- the press consists in a simple manner of a perforated sheet, just like the molded boxes, which is adapted to the dimensions of the boxes and which is placed on the filling and pressed down.
- the perforated sheet can remain on the box until it is removed from the mold, but it is also possible to apply separate perforated sheets in the subsequent stages for holding down and setting. This creates the desired orientation and entanglement of the fibers, which mechanically strengthens the bond.
- scraper shafts 18 can be arranged, which ensure a uniform degree of filling.
- the device should therefore preferably be started up and kept in operation continuously.
- the temperature and moisture treatment stages follow the press 17. First, hot air and hot steam can be blown in to activate the glue and the activatable lignin components 19.
- compressed air 20 can be blown in for drying and then in a further stage 21 either further drying air can be supplied, the exhaust air of which can be used for pre-drying in 20, or it can also be dried to residual building physics with the help of vacuum in 21.
- the mold boxes are circulated after removal from the mold.
- the degree of filling can be regulated via the scraper shafts 18 if they are height-adjustable.
- the temperature and humidity control is preferably carried out as follows:
- a mixture of hot air and superheated steam is driven in through the openings in the perforated plate below, the temperature and mixing ratio of which can be regulated.
- the gas mixture is fed into the mold until the material is heated to just below the boiling point of the liquid it contains.
- the moisture must be sufficient to enable the setting and reaction specifications, including the reactivation of the glues contained in the paper
- the renewed evaporation of the moisture is brought about by throttling the supply of hot air from the base element and, if necessary, by additional heating, and the resulting vapor / air mixture is sucked off through the drying plate body into the suction cover - negative pressure.
- the drying process of the plates does not take so long until the moisture also passes from the inside of the plate through the salts and fiber materials to the outside. diffused, but is carried out of the plate much faster by the air flow, which also brings evaporation energy with it.
- Another part of the evaporation energy is contributed by controlling the pressure in the closed form.
- a moisture residue that slightly exceeds the building moisture (approx. 10% weight moisture) can remain in the plate. As soon as the moisture has dropped so far, the plate can be dried and switched off and packed.
- Treatment of the moist plate with hot air can be used if the post-curing of certain adhesives, e.g. Effect lignin glue.
- the energy management of the gas central system can be optimized by minimizing heat losses through thermal insulation of the temperature-conducting pipes and surfaces and good seals, as well as recovering heat from the post-drying of the plates, the heat of condensation from the moist drying exhaust air and the superheated steam-hot air excess from steaming.
- the vaporization mixture can also be obtained by reheating the moist drying exhaust air (containing steam) and thus the moisture can be circulated.
