Definitions

  • the present invention relates to a vessel conveyor for the pneumatic conveying of, in particular, hard-flowing bulk material from a storage silo, in particular for conveying dry mortars and dry plasters, with a cone closure actuated by means of a pneumatically operating device relative to an inlet cone, and a method for filling this vessel conveyor.
  • Vessel conveyors are used for the pneumatic conveyance of bulk goods from storage silos, they are generally filled with the bulk goods from a storage silo via a rotary lock, and then the bulk goods are conveyed from the vessel conveyor to the point of use or packaging point by means of compressed air.
  • Such conveyors have already found their way into the building materials sector, so they are also used on construction sites to convey dry mortar and plaster to the processing point via hose lines.
  • the operation of such vessel conveyors is discontinuous. Compared to some continuously operating systems, these devices have the advantage that the storage silo is not pressurized and therefore does not have to be designed as a pressure vessel.
  • the usual vascular conveyors have disadvantages in that e.g. in the case of poorly flowing bulk materials, especially dry mortar mixtures, the filling of the vessel conveyor from the storage silo is disrupted.
  • vibrating and striking devices nor a one-time impact impulse during the opening process of a pneumatically operated cone lock, as known from DE-OS 26 57 742 can overcome this disadvantage.
  • Conventional ventilation of the lower part of the silo via nozzles and ring lines is also disadvantageous, because this can lead to segregation of the bulk material, especially in the case of dry mortar and plaster, which has a lasting effect on the workability of the conveyed material.
  • the vessel conveyor is expediently designed in such a way that it can be mounted below the outlet of the storage silo, which can be closed by a flap, e.g. by screwing or expediently by suitable clamping devices.
  • the conical inlet part of the vessel conveyor has an air-permeable porous lining, as known per se from GB-A-2 039 469. Between this and the conical inlet part there is a cavity with a connection for the compressed air used for ventilation.
  • the inlet cone is closed by a cone closure, the pneumatically operating opening mechanism of which is located together with the closing spring inside the vessel conveyor. Further details of the vessel conveyor according to the invention can be seen, for example, from the drawing and the associated description.
  • the operation of the vessel conveyor is as follows: After it has been connected to the storage silo, the lines for the ventilation air to the inlet cone and for the pneumatic actuation of the cone closure are pressurized with air at intervals of 1 to 2 seconds and compliance with a pulse pressure / pause ratio of approximately 1: 1 using generally a pressure of 2 bar, loosening of the incoming bulk material and opening of the cone closure taking place depending on the degree of synchronization of ventilation air pressure and cone closure pneumatics.
  • the pressure drop during the pulse pause should expediently only be 35 to 40%.
  • Adaptation to the flowability of the bulk material can be done by changing the pulse / pause ratio, changing the extent of the pressure drop during the pulse pause and finally by changing the degree of synchronization of the compressed air pulses for ventilation air and cone lock pneumatics. Finally, it is still possible to change the degree of synchronization during the filling process of the vessel conveyor to adapt to the particular flow behavior of the bulk material. Such changes can be made by means of provided manual controls if required, but they can also be made by automatic control depending on the filling level of the vascular conveyor, depending on the time.
  • a porous, air-permeable plate can be provided on the bottom of the vessel conveyor, which serves to loosen up the bulk material in the Vascular conveyor serves.
  • 1 denotes the vessel conveyor, which has a conically shaped inlet part 2, which is fastened to the lower part of the storage silo 3 by fastening means, not shown.
  • the lower part 3 of the storage silo is a flange piece with a built-in flap that can be opened and closed by lever 4.
  • the lower part of the vessel conveyor 1 is conical, is provided with a nozzle 5 to which the delivery line is connected and is connected to a flange piece 6, through the nozzle 7 of which the conveying air is supplied.
  • a porous plate 9 is arranged, which serves as a ventilation base for the bulk material located in the vessel conveyor during the conveying process.
  • the vascular conveyor 1 has a cone closure 10 with respect to the inlet cone, which is sealed by an annular seal 11.
  • the cone closure 10 is opened during the filling process via a pneumatic cylinder 12 by means of a piston rod 13 against the force of the spring 14 and is closed accordingly with the aid of spring force and pressurized air on the lower side of the double-acting pneumatic piston.
  • the opening and closing mechanism is held by a three-point suspension 15. 16 is the compressed air supply line during the opening process of the cone closure and 17 is the compressed air supply line during the closing process, which leads out of the vessel conveyor 1 at a position not shown.
  • the porous, air-permeable lining of the inlet cone is designated by 18.
  • Compressed air is fed into the space between the conically shaped inlet part 2 and the porous lining 18 via the nozzle 19 during the filling process in order to loosen up the bulk material in the inlet part.
  • the compressed air supply is also pulsed for the pneumatics of the plug lock.
