Definitions

  • the invention relates to a storage facility for bulk material, in particular for wood pellets, with a rigid support frame, which stands with stanchions on a storage room floor and attached thereto pliable fabric bag that is suspended with provided in its upper part loops on the crossbar of the support frame and an upper filling and a lower discharge device, wherein the pliable fabric bag is formed as a square or rectangular polyhedron with front wall, rear wall, two opposite side walls, floor and ceiling, wherein at least on the side walls on the outer surface of the fabric bag means are provided which these side walls Lift with decreasing level.
  • Storage facilities in the form of bag silos have long been known. They consist of a fabric bag, which is clamped on a holding frame and has an upper filling opening, and at the lowest point a discharge opening for the bulk material.
  • a particular advantage of these fabric bags is that their level measurement can be done very easily from the outside visually. The lower the level, the closer the side walls of the bag are closer together and the lower the discharge opening.
  • the support frame usually has a cubic shape and consists essentially of four uprights and four Auflegern which rest on the uprights and are firmly connected thereto.
  • the fabric bag On the outer surface of the fabric bag straps are attached in the upper area, with which the fabric bag is suspended from the four Auflegern.
  • the fabric bag usually has a square horizontal cross-section for better use of space.
  • this fabric bag has the disadvantage that it sags ever lower with increasingly lower capacity, so it must be mounted relatively high.
  • sack silos consist of a bottom open bag, which is connected at its lower edge fixed to a rigid, metallic funnel, the bottom portion has a connection to a suitable extraction and delivery device to the fuel boiler.
  • a suitable extraction and delivery device to the fuel boiler.
  • Such a sack silo is in the DE 202 11 226 U1 disclosed.
  • the capacity can be significantly increased and also the height can be lower.
  • a removal and delivery device a flexible tube with a flexible screw is described here.
  • a sight glass in the bag area is mentioned.
  • Another variant for solving the problem consists of using fabric sacks which, close to the height level of the discharge opening, have a stable, square, exposed tentering frame to which the fabric sack is fastened with additional, ground-level holding straps. By this tenter the sagging of the fabric bag is reduced with increasing emptying for the most part. However, this also makes the visual level check more difficult. Both variants also depend on the problem that the total weight of the device is substantially increased by the additional metallic parts, funnels or clamping frames or combinations of these two devices.
  • a disadvantage of this device is that even with completely lowered silo bottom below the same around the discharge around a dead volume is present, which is not available as a bulk storage room.
  • the present invention therefore has as its object to provide a storage facility for bulk material, in particular for pellets, which avoids the identified shortcomings of the known devices for storing bulk material, in particular the space within the holding frame almost completely utilized for storing the bulk material, the bulk material in the essentially completely removed from the fabric bag and a slight visual check of the level is given.
  • a storage facility for bulk material in that the bottom of the fabric bag rests in the filled state on the storage room floor and that near the bottom is a horizontal discharge device, comprising a screw conveyor, two bearings and a motor drive which lies partly inside and partly outside the fabric bag and is arranged parallel to the two side walls and extends partially or completely over the length of the fabric bag and this projects beyond at least the front, wherein the screw conveyor of the discharge is rotatably supported with their end portions in a respective bearing, and wherein the bearing with a drive motor provided and disposed outside of the fabric bag and the bearing inside or outside the fabric bag.
  • the pellets In the well-filled state, the pellets automatically fall into the discharge device arranged inside the fabric sack.
  • the devices which experience a reversible deformation due to the filling weight and the associated pressure against the side walls, contract with decreasing pressure against the side wall.
  • the side walls are raised with increasing emptying of the fabric bag.
  • the pliable fabric bag changes its shape from a four-sided to a three-sided lying polyhedron.
  • the storage facility is characterized by a simple visual representation of their filling volume, by a simple adaptability to the local space, such as a basement room, and a much more complete use of the existing space offer compared to the facilities of the generic type.
  • the fabric bag has on the outer surfaces of the two opposite side walls and on the rear wall such devices that lift the side walls and the rear wall with decreasing level so that the resting on the storage room floor part of the bottom of the fabric bag decreases even further.
  • the change in the shape of the tissue bag is very easily visually recognizable.
  • the device according to the invention therefore requires no further devices for filling level determination.
  • a horizontal discharge device preferably a screw conveyor which is parallel to the two side walls, preferably centrally located between the side walls and extends partially or completely over the length of the side wall, wherein the discharge means with their end portions in a respective Bearing is fixed, and wherein one of the bearings provided with a drive motor and outside of the fabric bag and the other bearing is arranged inside or outside the fabric bag.
  • the discharge device penetrates the cloth bag near the bottom at two opposite points. The passages are designed so that an unwanted discharge of bulk material is reliably prevented.
  • the ends of the horizontal discharge device screw conveyor
  • the associated bearing of the screw conveyor is then located outside of the fabric bag next to the rear wall.
  • the second bearing is located within the tissue bag in the immediate vicinity of its rear wall and holds it with its fixation on the storage room floor.
  • the discharge device such as a screw conveyor, projects only at the front of the fabric bag out.
  • the second bearing of the screw conveyor is arranged, either near the rear wall or slightly away from the rear wall in the direction of the bag center.
  • the second bearing within the fabric bag is not in the immediate vicinity of its rear wall and the discharge device does not have approximately the same length as the side walls. In this embodiment, it makes sense to provide reversible deformable devices also on the outside of the rear wall.
  • the devices which are provided on the outer surface of at least the side walls may be springs or rubber or permanently elastic bands which engage in fixing aids on the outer surface of the side walls of the fabric bag and in other fixing aids on the crossbar.
  • This fixation aids can be designed as loops, but also as eyelets or rings.
  • any other related fixing aid for the springs or bands is conceivable. They are arranged on the outer surface of the side walls of the fabric bag so that they are in the well-filled state in the ground-level area and their vertical arrangement is displaced by the devices at almost empty state of the fabric bag.
  • the storage facility after Fig. 1 consists of a rigid support frame 1, which is standing with its uprights 2 on a flat storage room floor and attached thereto pliable fabric bag 3, which is suspended with provided in its upper part loops 4 on the crossbar 5 of the support frame 1 and an upper filling 6 and a having lower discharge means 7 for the pellets.
  • the pliable fabric bag 3 has a substantially cubic shape with square cross section with front wall 8, rear wall 9, two side walls 10 and 11, bottom 12 and top 13.
  • the bottom 12 of the fabric bag 3 is in the well-filled state of the fabric bag substantially completely on the Storage room floor on.
  • means 14 are provided on the outer surface of the fabric bag 3, which raise the side walls 10 and 11 with decreasing level, like out Fig.
  • the location and extent of the discharge 7 can be well in Fig. 5 detect.
  • that variant is shown in which the discharge device 7 extends over the entire length of the fabric bag and both bearings 15 and 16 protrude from the fabric bag 3.
  • the bearing 16 may also be arranged on the rear wall 9.
  • Fig. 5 in side view and out Fig. 6 in front view in addition to Fig. 1 emerges, the bottom 12 of the fabric bag 3 is in the well-filled state almost completely on the storage room floor.
  • the devices 14, shown here as springs are fixed to the side walls 10 and 11 of the fabric bag 3 by means of loops 17 which comprise the crossbar 5 and loops 18 which are mounted close to the bottom 12 on the side walls 10 and 11 of the fabric bag 3 , In this state, they have their greatest length expansion.
  • the particular advantages of the storage device according to the invention are that the volume of space existing within the holding frame is utilized almost completely for the storage of the bulk material and a dead volume is avoided around the discharge around, that the bulk material can be substantially completely removed from the fabric bag, and that a slight visual check of the level is given, without the need for additional facilities are required.
