Definitions

  • the invention relates to methods and devices for the extrusion of a mixture of small plant parts and binders, in which the mixture introduced into the filling space of a piston cold extrusion press through a channel which determines the cross-sectional shape of the strand into and through an optionally provided with evasive wall sections , Hardening duct is guided in the compressed state.
  • the curing can be effected by heating, high-frequency exposure or the like. Details of such processes are known from DE-OSes 22 53 121, 25 35 989 and 25 54 280. In these methods carried out in practice, cold extrusion presses have been used which have a relatively short stroke of, for example, 150 mm, a relatively high frequency, for. B.
  • the structure of the strands produced in this way has an almost uniform orientation of the chips approximately parallel or in a convex stratification to the pressing surface of the strong press piston. Such strands break under bending stress parallel to this layering of the chips. Attempts have now been made to deform the chips in the not yet hardened state in a direction which is essentially perpendicular to the surface of the strand in order to harden the strand only afterwards. Such a teaching intended for particle board production can be found in DE-OS 17 03 414. This deformation of the chips was believed to be achieved by inserting the press ram into a stepped cylinder.
  • the invention has for its object to provide a method for extruding binder-containing vegetable small parts, with which it is possible to orient the chips from the parallel or convex to the pressing surface in an over the entire cross section of the strand to increase the To change the strength of the direction, at least to an intensely matted state.
  • the invention is based on the knowledge that the strength of an extruded object is higher, the less the individual chips remain in the predominantly parallel position to the extruded surface which is customary in known methods.
  • this task was solved in that the mixture was set in a flowing movement by means of an extended compression path during the compression.
  • the batch compresses in a ratio of about 2: 1 to 4: 1, preferably 3: 1, and / or if the batch has a feed rate of the extrusion piston of about 0.04 to 1.5 m / sec, preferably 0.05 m / sec, is compacted and / or if the strand is produced with a weight of 350 to 850 kg / m 3 , preferably 400 to 600 kg / m 3 .
  • Another essential area of application for the strands produced according to the invention is the processing into pallet blocks which fulfill all the conditions desired by the user, in particular resistance to breakage, impact resistance, shear strength, hardness and toughness of the lateral surface, adhesive properties and nailability of the end face, and weather resistance. Since the strands according to the invention have a lower weight than known, the technological advantages mentioned also come with the considerable weight savings and therefore cost reduction.
  • the stroke of the plunger with approximately 400 to 800 mm, in particular 600 mm, and the feed speed of the plunger with 0.02 to 1.5 m / sec, preferably 0.05 m / sec.
  • the piston in the PreBbub is expediently driven at a predominantly continuous feed rate, for which hydraulic controls are particularly suitable.
  • a further improvement of the invention is achieved in that the pressing surface of the piston in the central region is set back in relation to the peripheral region and is additionally corrugated in profile, it being advisable to design the pressing surface of the piston to be corrugated along the circumference and to reduce the individual shaft in the direction of the cross-section Let the center of the press surface run.
  • the cross-sectional design of the molding and curing channel also has a favorable influence, it being assumed that a cooled molding channel and then a heated curing channel are provided subsequent to an extrusion filling chamber.
  • the invention teaches that the outlet cross section of the molded channel is larger than its inlet cross section, but smaller than the inlet cross section of the first section of the curing channel, which is spaced a short distance therefrom, and that the curing channel at the end of this first section has an outlet cross section which is enlarged to the finished dimension of the strand .
  • the first section of the curing channel and the molded channel have rigidly arranged channel walls, whereas the subsequent curing channel in a manner known per se with wall sections supported in an evasive manner during the press feed is provided.
  • a not insignificant influence on the particular success of the invention is also the use of an older, not previously Public teaching according to the German patent application P 28 10 071.1 1 in a modified form, according to which it is proposed to form the top of the cylinder of a cold extrusion press with a reciprocatingly guided slide having a passage opening, which is the outlet opening of a batch feed container located above closes and opens. While in the proposed teaching the slide is moved back and forth only once per pressing operation, the invention proposes to carry out this movement at least twice, preferably three times, on each pressing stroke. In this way, on the one hand, a more even filling of the filling space is achieved, avoiding the formation of voids, and better venting of the air present in the cylinder.
  • this measure contributes significantly to making the degree of matting of the chips adjustable over the entire circumference.
  • the mixture of small plant parts and binders is brought into a filling space 3 through a feed container 1, the outlet opening of the feed container 1 being closed by a slide 2 which is lifted device 6 according to FIG. 2 can be moved back and forth.
  • a passage opening 5 located in the slide 2 coincides during this reciprocating movement to the outlet opening of the feed container 1 and allows the batch to fall into a filling space 3.
  • the slide 2 is moved back and forth several times, preferably three times, before each press stroke, which is carried out by a plunger 4, a better and more homogeneous filling of the precipitation volume 3 is achieved, and at the same time the venting of the filling volume 3 is also promoted.
  • the number of slide movements enables the degree of matting of the chips in the pressed strand to be influenced.
  • the stroke of the slide 2 is preferably dimensioned such that the passage opening 5 comes to lie at the end of each stroke outside the cross-sectional area of the filling chamber 3 or the outlet opening of the feed container 1.
  • the piston 4 has a stroke which is substantially increased compared to previously known embodiments, for example in the order of magnitude of 600 mm. It pushes the batch accumulated in the filling chamber 3 into a molding channel 7 which is designed to be cooled in the exemplary embodiment of the invention.
  • the inlet cross-section 10 of this shaped channel 7 is smaller than its outlet cross-section 1.
  • the length of the molded channel 7 is between 200 and 800 mm, while the increase in the outlet cross section 11 measured in one dimension is approximately between 0.5 and 4 mm greater than that of the inlet cross section 10.
  • a first section 8 of the curing channel adjoins the molding channel 7 at a certain distance, which is represented by the gap 15.
  • the width of this gap can be, for example, 3 to 5 mm. Since the first section 8 of the curing channel is heated, this gap 15 requires thermal insulation for the cooled one Form channel 7. Section 8 can also be heated with high frequency.
  • the inlet cross section 12 of the section 8 is in turn larger than the outlet cross section 11 of the molded channel 7. In one example, the magnification measured in one dimension is approximately 0.4 mm compared to the outlet cross section 11.
  • the first section 8 can have a length of approximately 1,500 mm.
  • the outlet cross section 13 of this section 8 has a larger clear width than the inlet cross section 12.
  • the difference between the two cross sections 12, 13, measured in one dimension, can be between 0.4 and 5 mm in the example. Only with this outlet cross section 13 is the finished dimension cross section for the strand to be formed.
  • the subsequent curing channel 9 then has the same size in its cross section as the outlet cross section 13.
  • the molded channel 7 and the first section 8 of the hearing channel are formed from preferably stationary channel walls, the actual curing channel 9 can have wall sections arranged in an evasive manner, as are disclosed, for example, in DE-05 25 35 989.
  • FIGS. 3 and 4 show how the end face 17 of an extrusion piston 4 can expediently be designed.
  • the piston 4 has a central bore 16. Accordingly, the piston is guided on a stationary rod which passes through the cylinder 3 in a manner not shown. In this way it is possible to strand also get a continuous hole.
  • the end face 17 of the piston 4 has raised and recessed areas 18, 19 which, in the exemplary embodiment, radiate from the edge of the piston towards the central area.
  • the central region of the piston is designed to be set back from the edge region.
  • the raised areas 18 have the greater width at the edge of the piston and taper towards the central area of the piston. The same is provided for the recessed areas 19. In this way, a meshing of the mass being compressed with the mass already compacted is brought about.
  • the chips in a certain flow flow flow experience a movement component directed transversely to the extrusion direction, which promotes the process of entangling the chips with one another.
  • the invention is not limited to the exemplary embodiments shown, but also extends to all other variants which, with knowledge of the object according to the invention, are suitable for solving them.
