An apparatus and method for the continuous production of materials, preferably for producing material boards made of essentially non-metallic material, comprising a continuous furnace (1) for continuously heating material (3) on an endlessly circulating conveyor belt (10) and a press (2) provided downstream in the production direction (15), wherein the continuous furnace (1) comprises a plurality of magnetrons (4) for generating electromagnetic waves and hollow conductors (5) with outlet openings (6) for feeding the waves into a radiation chamber (14). The invention is intended to solve the problem of reacting to various operating modes for the continuous furnace and, in particular, to heat up the material used in the best possible manner for later pressing. The invention is characterized in that a control or regulating apparatus (17) is arranged for controlling individual or grouped magnetrons (4) in order to provide them with different powers (L) for producing a differentiated power profile (9), preferably in and/or transversely to the production direction (15).

An incineration grate includes several levels including first and second grate bars arranged in rows alongside one another and in rows one above another, forming step-shaped combustion surfaces with their upper supporting surfaces. At least once in an area of the upper supporting surfaces, the first grate bars form, over their width, a smaller supporting surface for fuel than that of the second grate bars via a first shoulder disposed inwards in a direction of a longitudinal center plane. In an area of the upper supporting surfaces, the second grate bars have a supporting surface with a larger width in order to form an overlap with the first grate bars via a second shoulder disposed outwards over the width of the first grate bars. The second grate bars have at least one pin configured to be introduced into a pocket in the first grate bars and increase the larger width.

A layup machine for laying up and tacking sections of tape on a part to be produced, comprises: a first material drive/supply unit for supplying tape materials; first gripping means for drawing sections of tape from the first material drive/supply unit and for positioning the sections of tape in guide ways; a first cutter assembly for cutting to length the section of tape from the first material drive/supply unit; a motion table; and at least one tape tacking unit for placing on a tooling surface of a motion table and for tacking the sections of tape; characterized in that the layup machine furthermore comprises a second material drive/supply unit for supplying tape material; second gripping means for drawing sections of tape from the first material drive/supply unit and for positioning the sections of tape in guide ways; and a second cutter assembly for cutting to length the sections of tape from the first material drive/supply unit.
摘要:
A pelletizing press for producing pellets from material to be pressed, preferably from biomass, for use as fuel in fire places, wherein the biomass consists of cellulosic and/or lignocellulosic fibers, chips or shreds. In the pelletizing press, a dispersion chamber is formed by at least one die having a plurality of bores for pressing the biomass and at least by a lateral wall, and at least one roller rolling on a rolling surface of the die is arranged in the dispersion chamber. A pelletizing press of this method for producing pellets enables the formation of a dispersion chamber that, by means of at least one lateral wall, is as compact and sealed as possible relative to the prior art. At least two lateral wall parts are arranged to form a lateral wall; at least the first lateral wall part is arranged to be movable in relation to the second lateral wall part for carrying out a relative movement.
摘要:
A drum or drum segment for a drying apparatus of pourable material having built-in components arranged within the drum, which is rotatable about its central axis. The built-in components thoroughly mix and convey the pourable material from a drum entrance to a drum exit while guiding through a tempered gaseous transport fluid. Several support rings are arranged between the built-in components and the drum. The support rings are arranged to be statically supporting, but compensate tensile and compressive stresses in an elastic manner. The support rings are connected to the built-in components, a support frame and the drum, or a combination thereof A method for producing the drum or drum segments includes pre-mounting modules of built-in components and inserting the modules of built-in components into the drum or the drum segment.

The invention relates to a method for preheating a pressed material mat (14) spread on an endlessly and continuously circulating molding band (6) during manufacture of wood material boards, wherein microwaves from one or both press surface sides are beamed into the pressed material mat (14) to preheat the pressed material mat (14) and the pressed material mat (14) is compacted and hardened by application of pressure and heat after transfer to a continuously operating press (1). The invention consists of microwaves in a frequency range of 2400-2500 MHz being used to heat the pressed material mat (14), wherein the microwaves for each press surface side are generated from 20 to 300 microwave generators (26) with magnetrons (20) of a respective output of 3 to 50 kW. A device for preheating pressed material mats (14) is also provided, in which 20 to 300 microwave generators (26) with magnetrons (20) with an output of 3 to 50 kW and with a frequency range of 2400-2500 MHz are arranged in a conveyor furnace (4) per area side.

The invention relates to a pelletizing press for producing pellets, preferably from biomass, for use as fuel in fireplaces, comprising at least one die having a plurality of bores for pressing the biomass, at least one roll rolling on a rolling surface of the die, and at least one drive device for the die and/or the roll. The aim of the invention is to create a pelletizing press, which makes it possible to use a die having as low a height as possible, and thus as short a bore length as possible. The invention is characterized in that, for mounting the die, a carrier plate seated in a substantially planar manner against the die is arranged downstream of the die in the passage direction of the biomass. At least one opening for releasing the bores of the die is arranged in the carrier plate.
