    A stratified layer, for the manufacture of sheets, is formed from finely divided particles of material exhibiting a size distribution such as chips, fibers or the like, especially for the manufacture of wood chip panels, by forming a stratified mat on a substantially horizontal advancing surface by spraying particles of the material thereon, in such a manner that the finest particles are at at least one surface of the mat, through imparting a motion parallel to the direction of advance of the surface to the particles which are falling, causing the motion of individual particles to differ depending on the coarseness thereof so that different particles follow different parabolic trajectories and by collecting and removing particles which fall at least approximately vertically during said spraying.

    专利说明:

    The invention relates to the production of chipboards from bulk materials, mainly from wood chips, and can be used in the woodworking industry 5 .
    Is known to manufacture chipboard, comprising separating large particles, mixing them with a binder to form kov- 0 pa to the coating layer of fine particles and dust, the introduction of the carpet in a press and heated under pressure to obtain compression plate belt £ 1]. fifteen
    The closest to the proposed technical essence and the achieved result is a method of manufacturing chipboards, including the separation of wood particles with the separation of large particles, the formation of a moving in the horizontal plane of the layered carpet by scattering the wood particles in the direction of the molded carpet and pressing £ 2 J.
    A device is known for the manufacture of chipboards, including a feeding device, a belt conveyor, a separator, and a device for removing large particles £ 3] located under the feeding device.
    However, the known methods and apparatus have an increased labor-bone process in the separation of large particles.
    The purpose of the invention is to reduce the complexity of the process.
    This goal is achieved in that the separation of large particles is carried out in the process of dispersion by removing particles from the general flow with a vertical path of movement until they reach the surface of the carpet.
    In addition, the device for separating large particles is made in the form of a transverse conveyor with side turning walls, which is installed perpendicular to the conveyor belt with a vertical offset between the conveyor belt and the separator.
    The drawing shows a device for the manufacture of chipboards.
    The device includes a feeding device, which consists of a conveyor 1, rotating around the rollers 2 and 3, rotating in the same direction of the impellers 4 to align the wood particles 5 into a layer b of the same thickness. Under the feed device there is a belt conveyor 7, slotted nozzles 8 ( and 9, under which and above the belt I conveyor 7 there is a device for separating large particles. 'It includes transversely arranged mat 10 at a distance equal to its width, supports 11, transverse conveyor 12 with side pivot walls 13, rollers 14.
    The device operates as follows.
    Wood particles 5 of various diameters are poured onto an endless belt of the moving conveyor 1, aligned with the impeller 4 and upon reaching the roller 14 fall down, passing between nozzles 8 and 9 located in a horizontal plane against each other, through which in two opposite directions, perpendicular to the flow of particles 5, air is blown. As a result of this, the falling particles are sorted by the principle of air separation / so that the light particles first reach the conveyor belt 7 and form the lower layer of the mat 10. Heavier particles 5, moving along a parabola, fall on the layer already formed from light particles and form the inner the area of the mat 10, on which heavy particles fall. And finally, the lightest particles form the top layer of the mat 10. The formed mat 10 is surface pressed, the particles are <.
    5 ( located within the transverse conveyor 11, fall on it and are diverted to the side, without falling onto the mat 10 ..

    The device includes a feeding device, which consists of a conveyor 1 rotating around the rollers 2 and 3, rotating in one direction vanes 4 for leveling the wood particles 5 into a layer b of the same thickness. Under the feeding device there is a belt conveyor 7, slotted nozzles 8, and 9, below which is a belt conveyor (conveyor 7 is a device for separating large particles. It includes spaced across the formed mat 10 at a distance equal to its width, supports 11, a transverse conveyor 12 with lateral pivotal walls 13, rollers 14. The device operates as follows: Wood particles 5 of different diameters are poured onto an endless belt of the moving conveyor 1, aligned with the help of impellers 4 and When the roller 14 reaches the aisle, the nozzles 8 and 9, which are located in the horizontal plane opposite each other, pass through the air, through which air is blown in two opposite directions perpendicular to the flow of particles 5. As a result, the incident particles are sorted separation # so that the light particles first reach the belt conveyor 7 and form the lower layer of the mat 10. The heavier particles 5, moving along a parabola, fall on the layer already formed from light particles and form The mat of the mat 10, on which the particles get particles. And finally, the particles themselves form the upper layer of the mat 10. The formed mat 10 is subjected to surface pressing, the particles 5 that are within the transverse transporter 11 fall onto it and are retracted not on the mat. 10. Claim 1. A method for manufacturing particle boards, including separating wood particles with separating large particles, forming a horizontally moving laminate carpet by scattering wood particles into Forming a molded carpet and pressing, characterized in that, in order to reduce the laboriousness of the process, the separation of large particles is carried out in the process of dispersion by removing particles with a vertical trajectory of movement from the general flow until they reach the surface of the carpet. 2. A device for carrying out the method according to claim 1, comprising a power supply device, a belt conveyor, a separator and a device for separating large particles, which is located under the power of the device, so that the device for separating large particles is made in the form of a transverse a conveyor with lateral pivot walls, which is installed perpendicular to the belt conveyor with vertical displacement between the belt conveyor and the separator.
