Definitions

the present invention relates to a wind chamber used in particle board production on the spreading machine according to the preamble of main claim 1.
a main phase of the chipboard manufacturing process is the formation of the blank or the so-called spreading.
Spreading is done with special spreading machines. With these, a mixture of chips and binders is spread out on a grit belt conveyor to form a uniform, continuous carpet.
a typical spreading machine consists of so-called bunkers, floor conveyor, leveling brushes, unloading and distribution devices and a wind chamber.
the present invention thus relates to a wind chamber, which consists of a space delimited on the underside of a grit conveyor belt, on the sides of side walls, at the ends of end faces and on the top of a ceiling, in which the chips falling down on the distribution devices with the aid is carried on by air.
the air is introduced into the wind chamber through one end wall and removed through the opposite end wall.
a problem with the previously known wind chambers is that dust adheres to the ceiling of the wind chamber, from where it from time to time becomes uncontrollable Falls on the surface of the chipboard to be scattered, for example as a result of sufficient growth of the dust layer or accidental vibrations or the like.
the piles of dust that have fallen from the ceiling form clearly visible spots on the plate surface that spoil the surface, thereby lowering the quality level.
the invention has for its object to provide a wind chamber in which the problems outlined above are avoided. It is characteristic of the invention that the ceiling of the wind chamber is formed from a belt conveyor part.
the belt conveyor part is the return side of the floor belt conveyor of the grit bunker.
a scraper is attached in the wind chamber in order to remove the dust adhering to the belt conveyor part on the side of the wind chamber.
the wind chamber ceiling consists of a moving belt
the dust adhering to the belt is conveyed by the belt to the front wall, where the dust is removed from the belt in a controllable manner with the scraper and is conveyed out of the wind chamber by a conveyor, for example a spiral conveyor.
a conveyor for example a spiral conveyor.
spreading is carried out with special spreading machines.
1 shows a spreading machine from the prior art.
a mixture 2 of chips and binders is spread out to form a uniform, continuous carpet 3 on the spreader belt conveyor 4 arranged in the lower part of the spreader and moving in the direction of the arrow.
the spreader typically consists of bunker 5, floor conveyor 6 moving in the direction of the arrow, distributor conveyor 1, compensating brushes 7, unloading and distributing devices 8 and wind chamber 9.
the wind chamber 9 is a space delimited by grit conveyor belt 4, side walls 10, end faces 11, 12 and ceiling 13, in which the chips falling down on the distribution devices 8 are conveyed further by means of air.
the air is led through one end wall 11 into the wind chamber in the manner shown by arrows and removed through the opposite end wall 12 in the way also shown with arrows.
the finer chip particles fly furthest in the wind chamber and the coarsest particles become little of the air promoted.
a desired particle board structure is created, in which the surface of the plate is formed from an almost dust-like chip distribution and in which the average size of the chips increases towards the center of the plate.
the known wind chamber provided with a stationary ceiling 13 according to FIG. 1 therefore has the disadvantage that dust collects on the ceiling and falls from time to time in an uncontrolled manner onto the surface of the particle board.
the chamber ceiling is formed by the movable belt conveyor part 14, as which the return side of the floor belt conveyor 6 of the grit bunker is preferably used.
the dust adhering to the belt reaches the end wall 12 where the scraper 15 is attached.
the scraper 15 is e.g. fastened to the end wall 12 and its task is to scrape off the dust adhering to the belt 14 from the belt.
the dust falls into the trough 17, from which it is transported away by the spiral conveyor 16.
the scraper 15, the spiral conveyor 16 and the channel 17 preferably extend over the entire width of the belt 14 or at least over the width of the chipboard to be produced.
