Definitions

  • the invention relates to a vibration screening machine, in particular of the multi-deck type.
  • screening machines are fed by means of conveyors such as conveyor belts, screws, vibratory conveyors, etc.
  • a more or less uniform distribution of the material to be screened is achieved when it enters the screening machine.
  • the screenings are either heaped directly onto the screen mesh, or there is a so-called baffle plate or feed plate inside the screen machine, onto which the bulk material is placed in order to protect the screen mesh from wear. The bulk material then falls from the baffle onto the screen mesh.
  • baffle plate or feed plate inside the screen machine onto which the bulk material is placed in order to protect the screen mesh from wear.
  • the bulk material then falls from the baffle onto the screen mesh.
  • the result of this type of loading is that the active screen surface is not optimally used because certain screen surfaces in the inlet area are not covered with product, or the product distribution is different in the width.
  • the layer height in the middle is much higher than on the sides, so that there is an overload in the middle and an underload on the side.
  • the invention aims to avoid the disadvantages mentioned and to solve the problem of creating a screening machine in which the material is evenly distributed when it hits the screens and a pre-segregation is already formed, so that the screens are optimally used for their actual task can with the result that the size of the screening machines can be reduced and thus the cost can be reduced.
  • the distribution and segregation devices are components which can be interchangeably attached to the frame of the screening machine.
  • the frame housing is then designed so that different in the inlet area Distribution and segregation devices can be installed to adapt to the substance and product ion properties.
  • the product is supplied from very different directions, and it is therefore necessary to choose differently designed distribution and segregation devices. It is only important that all have the same connection dimensions on the housing and can therefore be replaced at any time like a modular system.
  • a box closed except for a filling opening and a drain opening for the material to the screen deck can be used, the bottom of which has a roof-shaped inclination from the center to the sides in the entry area for the product, which is then followed by a level one to the screen deck floor area inclined towards flat.
  • these can be height-adjustable distributor plates which can be provided with sawtooth-shaped or rectangular cutouts in their lower regions.
  • baffles or vanes on the distribution floor, which are attached from below through the distribution floor and are adjustable.
  • a distribution and segregation device can be with one or more inlet ports. and a drain opening for the housing provided with the screen deck, in which two distribution plates are arranged above the horizontal bottom plate, which are inclined roof-shaped from the center outwards and can be adjusted to different inclinations. This adjustability is important because the flow properties of the products are very different and so the inclination can be precisely adapted to the product.
  • the front edges of the distribution sheet should be cut obliquely in such a way that the lateral areas are further back compared to the areas in the middle. This significantly improves the product distribution across the width.
  • height-adjustable discharge plates should be provided on the front edges of the distribution plates.
  • the joint between the distribution plates can be covered by a roof-shaped adjustable shielding plate, baffle plate or distribution plate / the material supplied, which is attached above the adjoining edges of the two distribution plates.
  • AM inlet of the screening machine i.e. A distribution and segregation device 11 or 12 is attached as a kit in front of the uppermost sieve tray 14, so that the sieve machine user can easily adapt to different operating requirements.
  • the length of the distribution and segregation device depends on various factors, such as material properties and width of the screening machine. For wide screening machines, it is conceivable to place two distribution devices next to one another, which then have practically two inlets.
  • FIG. 2a shows a section through the device and FIG. 2b shows a view from above of this device, which consists of one but one fill opening 18 and one drain opening 19 on which the goods are opened the sieve bottom is delivered, closed / there is a box 17 in which a bottom part 20 is arranged between side walls, which is roof-shaped in the area of the filling opening 20a and merges towards the drain opening into a flat, inclined part 20b. Due to the roof-like bottom part, which converges to a saddle in the middle, the goods entered are distributed immediately after all seldom. The vibration then transports the product towards the sieve bottom, and at the same time a stratification and segregation process takes place due to the vibration.
  • a distribution plate 21 which can be adjusted in height and can be provided with recesses 29 or 30 in its lower region, as can be seen in FIG. 3, can be provided above the base 20b. Adjustable baffles or flags can also be attached to the floor 20b for the purpose of more even distribution of the goods.
  • an observation opening at box 17 auci 24 can be provided, through which the uniformity of the distribution of the goods can be observed.
  • the incoming material migrates after the division through the shielding and guide plate 26 onto the plates 27 and is conveyed there by the vibration on the one hand in the direction of the screen fabric and on the other hand by the inclination to the sides.
  • the oblique cuts of the sheets 27 ensure that the layer height is evenly distributed over the width over the discharge edges.
  • the discharge edge can be designed differently, i.e. a small weir can be formed, or it can also be set at an angle and thus ensure that the discharge edge throws the material over the full width onto the underlying feed plate 29, which now initiates yet another segregation process. From there it finally flows onto the screen mesh.
  • the inlet connection 25 can also be designed differently and can also be arranged somewhat off-center, if. this becomes necessary due to the installation situation.
