Definitions

  • the invention relates to a conveying device for bulk material and / or fiber material, in particular a blowing insulation conveying device, comprising a loosening device for loosening the bulk material and / or fiber material, wherein the loosening device comprises: a housing having a longitudinal axis, the conveying direction of the bulk material to be conveyed and / or fiber material, and at least one loosening element comprising a shaft which is rotatably mounted in the housing about an axis and driven by a motor, wherein the axis is arranged perpendicular to the longitudinal axis, wherein on the shaft a number of impact elements are rotatably mounted.
  • a generic device is for example from the US 3,051,398 A known.
  • a device of this type is used in particular to spend a fibrous insulating material - promoted in a stream of air - to its destination, for example, in hollow chambers, which are formed in a roof truss to fill said hollow chambers tightly with the insulating material.
  • Such a device is further, for example, from the EP 1 520 948 A2 known.
  • the material delivered pressed in a container is loosened up by the conveyor device by means of a chopper and the material thus prepared is conveyed in a transport line in the airstream to its destination.
  • the device that accomplishes the loosening of the material is also referred to as a rotary valve.
  • the fiber material may be cellulose. If, what has recently been preferred, the fiber material is made of wood, special difficulties arise. The wood fibers are pressed in turn, d. H. Delivered in highly compressed form, then as fanned wood fibers to Dämmstelle, for example, in hollow chambers of a roof, to be promoted. Due to the different structures of the fibrous wood particles, these do not disintegrate into individual fibers as easily as in the case of cellulose.
  • the invention has for its object to provide a conveyor of the type mentioned in such a way that it is possible, even difficult ceremonimaschinende materials, in particular wood, sufficiently mecanicmaschinen and optimally promote, so that the volume to be filled with the fiber material well and Hohlstellen- can be filled freely.
  • the initially highly compressed present insulating material is therefore to be frayed in an improved manner and distribute as evenly as possible in a compartment to be filled with him.
  • the device should be simple in construction, so that a cost-effective production is possible.
  • the housing is designed as a tube with a circular cross-section, wherein in the housing in the conveying direction consecutively at least two loosening elements, preferably three loosening elements are arranged, wherein two consecutive in the conveying direction Auflock ceremoniess institute for opposing rotation are formed, wherein the impact elements extend from the shaft to the inner circumference of the tubular housing, wherein in the conveying direction before and / or behind the last impact element, a device for blowing air is arranged.
  • Said loosening device is provided as a separate element, which is effectively arranged between the device for loosening the pressed material (rotary valve) and the end of the fiber material blown-in hose.
  • a preferred solution provides that two loosening elements following one another in the conveying direction rotate in opposite directions. Accordingly, in the case of three loosening elements, the first and the third loosening element rotate in the same direction, while the loosening element arranged therebetween rotates in opposite directions.
  • the striking elements accordingly extend from the shaft to the inner periphery of the tubular housing. This is to be understood that only a sufficient gap for proper function between the radially outer end of the striking elements and the housing inner circumference remains when the striking element comes closest to the housing inner circumference.
  • This gap is preferably in the range between 3 and 30 mm, preferably between 5 and 15 mm.
  • the striking elements may extend radially away from the shaft. It is also possible for the impact elements to extend away from the shaft at least in sections at an angle, preferably between 10 ° and 50 °, to the radial direction.
  • a particularly good loosening effect is achieved if a first loosening element is arranged in a region of the housing lying in the conveying direction, the impact elements extending radially away from the shaft of the first loosening element, and a second loosening element being arranged in a region following in the conveying direction wherein the striking elements extend from the shaft of the second loosening element away from the shaft at least in sections at an angle to the radial direction.
  • the impact elements can be connected to each other at a location spaced from the shaft, for example by a ring having a slightly smaller diameter than the inner diameter of the tubular housing.
  • the impact elements can be rotatably connected via a positive connection, in particular via a polygonal profile, with the shaft.
  • a striking element can also be connected to a hub part, in particular welded, and the hub part can then be non-rotatably connected via the positive connection with the shaft.
  • a further improvement of the loosening effect and improved further promotion of the fiberized material are achieved in that a device for blowing in air is arranged in the conveying direction before and / or behind the last impact element in the conveying direction.
  • This device can be designed as a ring element, in which a number of air injection nozzles are arranged over the circumference. Angular adjustment of the air injection nozzles, the fiberized material can be imparted a twist in the delivery hose, which supports the promotion of the material.
  • a particularly good defibration and promotion of the material is achieved when both said end of the loosening device and at the end of the tube each said means are provided for blowing air, preferably at the beginning of the loosening device.
  • the impact elements of a loosening element which are arranged on the shaft, thus forming a kind of rotation grid, which is arranged rotationally driven in the housing.
  • the tubular housing with the striking elements according to the invention which come close to the housing inner circumference, allows efficient fibrillation of the material to be conveyed with the significant advantage that there is a very compact and space-saving device that is easy to transport. This is important because of the purpose of the device since it must be mobile.
  • a conveyor 1 for conveying wood fibers 2 is outlined.
  • the wood fibers have a substantially linear extension and a length between about 2 and about 8 mm.
  • the wood fibers 2 are delivered in a pressed state and are initially in a container 15. It is necessary to loosen up the present in a pressed state wood fibers and promote, for example, to bring them tightly packed in cavities of a roof truss can.
  • the conveyor device 1 a device 12 for loosening the pressed wood fibers, which is sometimes referred to as a rotary valve.
  • the device 12 performs a chopping process by which the fibers are loosened.
  • the already partially frayed material 2 passes through a hose 13 in a conveying direction F to a loosening device 3.
  • This device further loosens the fiber material 2 and brings it into a virtually completely frayed state.
  • Via a further hose 14, the frayed material 2 is further blown in the conveying direction F to its destination.
  • devices 11 for blowing in air are provided at three points, namely in front of the loosening device 3, behind the loosening device 3 and at the end of the hose 14.
  • the devices 11 include nozzles that the Loosening and turbulence of the wood fibers 2 favor. If appropriate, further such devices 11 can be arranged in the flow or conveying path of the wood fibers 2.
  • the loosening device 3 is outlined with different details.
  • the loosening device 3, which constitutes a separate element in addition to the device 12, has a tubular housing 4 which has a longitudinal axis L.
  • the longitudinal axis L coincides with the conveying direction F.
  • the loosening elements 5 are rotating components which rotate about an axis a which is perpendicular to the longitudinal axis L.
  • a shaft 6 is provided, which is rotatably mounted in the housing 4 by means of suitable bearings 16.
  • a number of striking elements 8 are arranged in a rotationally fixed manner on the shaft 6.
  • the rotary drive of the shaft 6 is effected by a motor 7, which preferably rotates the shaft between 2.500 and 4,000 revolutions per minute, in which case the two loosening elements 5 preferably rotate in opposite directions.
  • the striking elements 8 can, as it Fig. 3 shows, so be arranged on the shaft 6, that they extend radially. Alternatively, it is also possible - and show that FIGS. 4 and 5 for two alternative embodiments - that the striking elements 8 extend away from the shaft 6 at an angle ⁇ to the radial direction.
