Definitions

  • the invention relates to a rapid dryer designed as a centrifugal wave dryer, which is provided at one end of its housing with at least one opening for the supply of the material to be dried and the hot gas and which has discharge devices for the dried material and for the exhaust gas at the other end of its housing .
  • Centrifugal wave dryers are dryers with a short residence time.
  • the dryer is equipped with internals that affect the dwell time. Centrifugal waves distribute the supplied moist material in the housing of the dryer. As a result, the material which is exposed to the hot gas has a large surface area, so that the prerequisites for rapid and intensive evaporation of the moisture adhering to the material are created. Since the drying takes place in parallel flow, the thermal load on the material is relatively low.
  • the movement of the material in the dryer is caused by the centrifugal shafts equipped with throwing vanes and by the hot gases.
  • the known dryers of the type described above generally have separate discharges for exhaust gas and material.
  • An opening is provided in the bottom of the dryer housing for material discharge. This opening is provided with a lock through which the dry material is discharged.
  • catch boxes are provided at the lower openings of the dryer, in which the foreign bodies are to be collected.
  • catch boxes often do not serve their purpose because material also gets into the catch boxes and gets stuck there. There is then no more space for the foreign bodies; unless the catch boxes are emptied at regular intervals via a lock. However, this creates an undesirable accumulation of material to be discarded or a second material flow which is difficult to examine for foreign bodies.
  • the invention aims to avoid the disturbances caused by foreign bodies and wants to ensure that foreign bodies that have entered the dryer are removed from the dryer as quickly as possible and with as little useful product as possible.
  • the common discharge device for the dried material and for the exhaust gas should be directed upwards to avoid settling and sticking of the material.
  • the collecting basket is expediently arranged at the end of the housing of the rapid dryer.
  • the foreign bodies have to travel a relatively long way in the dryer; however, it is guaranteed that every foreign body finally gets into the collecting basket.
  • At least one collecting basket is provided on each side of the housing. This measure further shortens the path that each foreign object travels in the dryer.
  • a further improvement of the invention results from the fact that the collecting baskets are essentially formed from grate bars, wherein - according to a further feature of the invention - the grating bars of the collecting baskets are at a distance from one another which is greater than the grain size of the material to be dried. This ensures that foreign objects remain on the grate while the material to be dried passes freely through the collecting basket.
  • the side removal of the foreign matter from the dryer can be carried out easily at a standstill the discharge provided in the area of each collecting basket is only closed by a simple flap.
  • the discharge opening provided in the area of each collecting basket is provided with a lock. This allows foreign matter to be removed during dryer operation.
  • each lock is connected to a control device which opens and closes the lock at regular intervals.
  • 1 and 2 consists essentially of a housing 1 with internals provided therein and with throwing blades 3 provided with centrifugal shafts 4. At one end of the housing 1 is an opening 5 for the supply of the material to be dried and another Opening 6 is provided for the entry of the hot gas. At the other end of the housing 1 there is a discharge device 7 for the dried material and for the exhaust gas.
  • a collecting basket 8 is attached to a side wall of the housing 1. But it can also be on the opposite A further collecting basket 8 can be provided on the side wall of the housing 1. Furthermore, it is possible to arrange several collecting baskets 8 one behind the other over the length of the housing 1. In the area of the collecting basket 8 there is a discharge opening (see FIG. 2), which is closed with a simple flap 9, but which can also be provided with a lock 10.
  • the grass catcher 8 has grate bars 11 (see FIG. 1), the spacing of which is greater than the grain size of the material to be dried.
