Definitions

  • the invention relates to a device for storing and transporting bulk material, in particular mixtures produced in batches in a mixer, which has a bunker with a closable bottom opening and a transport device arranged under the bottom opening of the bunker for the bulk material discharged from the bunker.
  • a bunker between the mixer and a transport device provided for the removal of the mixed material or finished bulk material mixture to a consumer, which serves for the intermediate storage of the bulk material mixture and has a bottom opening through which the bulk material mixture can be used if necessary on the transport device, for example a conveyor belt or a screw conveyor.
  • the bunker intended for the intermediate storage is expediently arranged directly under the mixer. So that this bunker does not build too high, it has a rectangular shape in plan, which is based on the length and width of the mixer, which preferably has a drum-shaped container, the mixer of which is arranged with a horizontal longitudinal axis and expediently one over the entire length of the cylindrical container extending drainage opening or bottom opening.
  • Such an elongated bunker also has an elongated bottom opening because this also enables a low overall height.
  • the conveying devices used in such systems extend in the longitudinal direction below the bottom opening of the bunker intended for the intermediate storage in order to transfer the intermediate stored material over the entire length of the bunker to the conveying device and to be able to convey it further in one direction or the other.
  • a feed container which has flaps which can be opened one after the other in a floor opening, which are freely pivotable and which, in the event of unequal loading by bulk goods lying thereon, pivot one after the other in order to let bulk goods fall through.
  • These hinged flaps are only opened by gravity and can only be controlled to a limited extent in a single, fixed opening sequence, so that this known feed container is not suitable for intermediate storage of bulk material, which in any sequence can be discharged onto a conveyor belt that is reversibly drivable (DE -B-1 054 377).
  • the invention has for its object to provide a device for storing and removing bulk goods such as bulk mixes produced with an upstream mixer, which can temporarily store the mixed bulk goods in a bunker and release them gently and without particularly high and pronounced load peaks on a downstream transport device , so that this transport device conveys the mix according to need and to different delivery points.
  • the bunker Due to the fact that the bottom opening of the bunker has a plurality of closures arranged in a row one after the other, which can be opened one after the other in a controllable sequence, the bunker can be emptied in such a way that there is no sudden peak load on the downstream transport device, but gradually with it the bulk material in the bunker is loaded and accordingly there are no excessive load peaks, but rather the load is largely balanced. This ensures that the bunker is emptied evenly and dust-free onto the secondary formwork tete transport organ or the downstream transport device also possible if bulk goods are treated that tend to dust or even flow, such as fine lime or gypsum mixtures.
  • the lamella-like flap closures provided according to the invention have the advantage over slide closures known in the case of emptying openings for bunkers that they suddenly release the discharge opening on a given discharge surface, so that slide closures require long displacement paths and, accordingly, too long emptying times.
  • the bunker designed according to the invention is funnel-shaped, at least in the lower region and in the cross section running at right angles to its longitudinal extent, in order to ensure that the bulk material located therein slides down to the emptying opening.
  • vibrating devices can be provided on the bunker and on the outside thereof, which are particularly useful when bulk material that is difficult to transport and tends to form bridges is processed.
  • wedge-shaped intermediate pieces or tabs between the discharge openings which are arranged one behind the other and are rectangular or preferably square in plan, which guide and guide the bulk material located above in the bunker in the direction of the individual closures or the outlet openings formed by them.
  • a mixer (1) with a drum-shaped, lying cylindrical mixing container (2), in which a mixer (4) rotatable about a horizontal axis by a motor (3) is located, there is an elongated hopper (5) with a funnel-shaped cross section ) in which the bulk material mixture produced in the mixer (1) can be emptied suddenly if flaps (7) of the mixing container (2), which extend over the entire length of the mixing container and open a bottom opening (6), are opened, as in FIG. 2 is indicated.
  • the bunker (5) is provided with an elongated bottom opening (8) which is located above a transport and filling device (9).
  • This transport and filling device (9) contains a conveyor belt (10) on the encapsulated side, which can be reversibly driven by a motor (11), so that it can selectively transfer the bulk material discharged from the bunker (5) through the bottom opening (8) to a filling funnel ( 12) can convey at one end of the device (9) or a discharge nozzle (13) at the other end of this device, from where the bulk material is either packed or filled for further transport or immediately processed.
  • Vibrators (14) are arranged on the outside of the bunker (5) and are provided in order to dissolve bridges of the bulk material that may form in the bunker (5).
  • the bottom opening (8) of the bunker (5) is subdivided into a number of individually operable closures (15), in the embodiment shown in a total of six closures (15), each of which is provided with its own drive (16).
  • These drives (16) are to be actuated individually and in a controlled sequence or sequence so that the bulk material in the bunker (5) cannot be fed onto the conveyor belt (10) one after the other, but step by step, so to speak.
  • the closures (15) and their drives (16) can be opened in succession in accordance with the direction of conveyance of the conveyor belt (10) such that when the conveyor belt (10) (viewed in FIG.
  • FIG. 3 and 4 is one of the closures (15) of the bottom opening (8) of the bunker (5) in part sectional top view and side view.
  • the bunker (5) shown in Fig. 1 has a total of six such closures (15).
  • Each closure (15) has a frame (17) which is approximately square in plan and which can be fastened to the underside of the bunker (5) with circumferential flanges (18).
  • the square opening (19) of this frame (17) is formed by vertically extending side walls (20) made of abrasion-resistant material such as plastic, which has a smooth surface.
  • a total of three flaps (21, 22 and 23) are provided, each of which can be pivoted about 90 ° about a horizontal axis (24), so that they are about 90 ° between a horizontal closed position, in 3 and 4, and can be pivoted to a vertical opening position.
  • the closure flaps (21 to 23) overlap one another and here contain groove-shaped recesses (25), so that the mutually opposite groove-shaped recesses of the individual closure flaps can engage in a claw-like or labyrinthine manner, as shown in FIG. 4, which is necessary for a good seal is.
  • closure flaps (21 and 23) can lie with their long sides sealingly under the corresponding side wall (20) of the frame (17) in the closed position, all closure flaps (21 to 23) with their front ends are matched to the corresponding side wall of the opening ( 19) arranged so that there is only a very small tolerance and accordingly no bulk material can leak from the end walls of the closure flaps when the closure flaps are in their closed position.
  • Each closure flap (21 to 23) is provided at its two ends with a holder (26) on which there is a bearing journal (27) which is rotatably mounted in a bearing plate (28) fastened on the outside of the frame (17) .
  • a lever (29) is fastened to the outer end of each bearing pin (27), the outer ends of the three levers (29) being fastened in an articulated manner to a control rod (31) by means of pins (30) in order to close all the flaps (21 to 23) to be able to operate simultaneously.
  • the drive (16) is provided, which in the exemplary embodiment shown has a pneumatic cylinder (32) as the drive element, the piston of which can be reversibly adjusted via a control (33).
  • the piston rod (34) acts via a toothed rack on a gear wheel (35) which is arranged on an extension (36) of the one pivot pin of the central closure flap (22).
  • displacement movements of the piston rod (34) are converted into rotary movements of the hinge pins (27) of the central closure flap (22) in order to move them from the horizontal closed position to the vertical open position and vice versa.
  • the other two flaps (21 and 23) are taken, so that all flaps are adjusted simultaneously when the pneumatic cylinder (32) of the drive (16) is actuated.
