Definitions

  • a method and a system for pneumatically conveying a granular material out of a drying store are described in detail below.
  • the present invention relates to a method of pneuma ⁇ tically conveying a granular material away from a drying store in the general manner specified in the introductory clause of claim 1. It is well known to provide in a drying store a system of spaced, parallel air ducts arranged on the flat store bottom and connected at one end with a blower while being closed at the other ends.
  • the duct side walls are provided with a row of openings immediately above the bottom level, and each opening is provided with an air guide flap which is arranged obliquely to the longitudinal direction of the duct in such a manner that it tends to guide the local air flow outwardly and forwardly along the duct, thus tending to cause pneumatic displacement of the material adjacent the duct or rather of the material lo- cated in the groove as constituted by the elongate space between every two neighbouring ducts. Adjacent the closed duct ends this or these grooves merge in an outlet opening in the floor or wall of the store, this or these outlet openings being closable by suitable outlet valve means.
  • the material is caused to be conveyed in the manner stated in the characterizing clause of claim 1, i.e. by making use of the duct itself for containing the conveyed material as introduced by ejection through the wall openings.
  • the outlet as constituted by the duct end itself is made closable, then the duct is still usable for alternatively supplying dry ⁇ ing air to the material through the ejector openings, and the novel main results of using the method according to the invention will be that the conveying is effected by way of an air and material intake through the wall open ⁇ ings, whereby no dust is blown out in the store, and that a possible intrusion of grains into the duct during the drying phase will be unimportant, because the intruded ma- terial will automatically be removed by the subsequent conveying phase.
  • the invention also comprises a system for air drying and pneumatically conveying a granular material according to the above method, as specified in appended claims 2-4.
  • Fig. 1 is a schematic perspective view of a system according to the invention
  • Fig. 2 is a more detailed view of a partial length of an air duct therein
  • Fig. 1 is a schematic perspective view of a system according to the invention
  • Fig. 2 is a more detailed view of a partial length of an air duct therein
  • Fig. 3 is a side elevation of a portion of one of the ducts.
  • the system shown in Fig. 1 comprises a number of spaced, parallel air ducts 2 placed on the bottom face 4 of a grain store, the four side walls 6 of which are shown schematically only. At one end the ducts 2 are connected with a manifold 8 through which air may be blown into the ducts from a fan 10.
  • the opposite ends 12 of the ducts 2 are located flush with the outside of the associated side wall of the store, such that the wall seals the space between the ducts, and above the duct ends 12 is arranged a valve plate 14 which, by means of any suitable actuator means such as a cylinder 16, is movable between the illu ⁇ strated raised or open position, in which the " duct ends 12 are uncovered, and a lowered or closed position in which all duct ends are closed.
  • the duct ends 12 communicate with a receiver hopper 18 arranged so as to guide grain material discharged through the duct ends 12 to some suitable receptacle or conveyor.
  • the ducts 2 are de ⁇ signed as inverted ⁇ - or V-profiles having in each of their opposed lowermost side portions a row of openings 20.
  • valve plate 14 assumes its lowered, closed position and air is supplied to the ducts 2 from the fan 10, the air will be blown out through the openings 20 and thus be supplied as drying air to the gra ⁇ nular material as housed in the grain store, filled into the store e.g. through an open top thereof.
  • the openings 20 will hereby act as ejector openings, through which the grain material is drawn into the ducts and thereafter moved through the ducts to be discharged into the hopper 18 through the open duct ends 12.
  • each of these openings is provided with a guide plate 22 projecting inwardly and forwardly into the duct from the upstream edge of the respective opening 20.
  • Each guide plate 22 is of a generally triangular shape, and it seems to be particularly advantageous that the lower edge of these guide plates is somewhat upwardly inclined, diverging from the bottom surface 4. As shown in Fig. 2 the guide
  • OM plates 22 may be constituted by bent flap portions of a bracket member 24 used as a cross spacer element between the opposite edges of the duct 2. Additionally the bracket member may serve as a means for securing the duct to the floor by means of a screw through a hole 26 in the bracket member 24 (Fig. 2) .
  • the ducts may be assembled from a number of duct elements 28, which may advantageous ⁇ ly be provided with a bracket member 24 adjacent one end thereof and with side incisions 30 at the opposite ends, whereby the ejector openings 20 at these places are formed by the juxtaposition of the duct elements.
  • duct elements 28 may advantageous ⁇ ly be provided with a bracket member 24 adjacent one end thereof and with side incisions 30 at the opposite ends, whereby the ejector openings 20 at these places are formed by the juxtaposition of the duct elements.
  • one end of the elements may be provided with a rim portion 32 overlapping the adjacent end of the next ele- ent.
  • the ducts 2 should not necessarily extend parallelly to each other along, their entire length, especially adja ⁇ cent their outlet ends they may be arranged in a generally converging manner such that they all merge in a single outlet opening.

Abstract

Sur la surface du fond d'un magasin d'un materiau granulaire est dispose un systeme de conduites d'air (2) connectees a une extremite a une soufflante (10) et ayant a leurs extremites opposees une soupape de fermeture (14). Les parois laterales des conduites sont pourvues d'ouvertures (20) permettant a l'air de sortir dans le materiau pour secher celui-ci lorsque la soupape (14) est fermee. Lorsque la soupape (14) est ouverte l'air s'ecoule dans chaque conduite et les ouvertures (20) sont concues comme des ouvertures d'ejection de sorte que le materiau est aspire dans la conduite puis transporte hors du magasin.
