Definitions
- the invention relates to a Nachrieselschutzvorraum for a filling station for filling containers with a Bulk material according to the preamble of claim 1.
- Such a post-trickle protection device is known from EP-A-490 607 or EP-A-709 291.
- Containers such as sacks or so-called Big Bags, barrels or containers are usually in a special For this purpose designed filling station filled with a bulk material.
- the filling station has a filling tube, via that the bulk material gets into the container.
- parts can of the bulk material, for example, on the inner wall of the Adhere to the filling tube, trickle out of the filling tube and into the Environment, for example, to the floor of the room fall, in which the filling station is located.
- shut-off devices provided, which the filling tube during a container change close to prevent the sprinkling of the bulk material.
- the flap parts are mechanical or hydraulic Facilities collapsed completely or at least partially disposed in the filling tube. Through this the flap parts actuating devices is the bulk material flow obstructed in the filling tube.
- the object underlying the invention is to a Nachrieselschutzvorraum of the type mentioned above create, which obstructs without the Schuttgutstrom in the filling tube Actuators for the flap parts manages.
- the filling station shown in Figure 1 has a filling tube 1, over which a bulk material in a container 2, such as For example, a bag or a bag passes.
- a bulk material in a container 2 such as For example, a bag or a bag passes.
- a Nachrieseln of the bulk material in a container change to avoid, at the moment no container to the filler neck the filling tube is connected is a Nachrieselschutzvorraum preferably at the lower end 3 of the filling tube 1 provided during the container change the Can fill 1 to the outside.
- the Nachriesel conspiracyvorraum comprises a two-part Flap with flap parts 4 and 5, which are attached to a shaft 6 are, which sits in an annular holder 7, the is attached to the lower end of the filling tube 1, or directly attached to the filling tube 1 or inside the filling tube 1 fitting is arranged.
- the two-piece flap has a dimension, which corresponds at least to the filling tube inner cross-section, so that they in the closed state, the in Figure 2 and FIG. 3 shows the interior of the filling tube 1 complete to the outside completely.
- the two flap parts 4 and 5 of the two-piece flap are pivotable about the shaft 6 and in the illustrated in Figure 4 Position, that is in the direction of the bulk material flow and thus in the pouring station shown in FIG collapsible downwards or forwards. As in FIG. 4 is shown in detail, lie in the folded state both flap parts 4 and 5 with one of their outer surfaces together.
- a swivel drive in particular a double-piston swivel drive 8, 9 provided for each flap part 4, 5, to swing it around the shaft 6.
- this is the shaft constructed of three separate parts 10, 11, of which the two outer 11 are connected to a flap part 5, while the inner shaft part 10 is connected to the other flap part 4 is.
- the drives 8 and 9 are at driving points 12, 13th each with the outer shaft parts 11 and the inner shaft part 10 in conjunction, which are shown in Figure 7.
- the Shaft 6 may also be formed in two parts, each Flap part 4.5 is connected to a shaft part.
- the driving points 12, 13 for the outer and inner shaft parts 10, 11 are preferably as grooves formed, to which the drives 8, 9 are coupled, as shown in detail in Figure 7.
- FIGS. 8, 9 and 10 show an embodiment of the drive device, which in contrast to the training, the above has been described, formed inside lying in the filling tube is.
- two are pneumatic or hydraulically operated cylinder 14, 15 are provided, which via lever 16, 17 move the two flap parts 4 and 5 about the shaft 6.
- the cylinders 14, 15 are in the filling tube one or both sides mountable.
- FIG. 11 shows an exemplary embodiment of the invention
- Nachrieselschutzvorraum without external drive components gets along.
- the drive device is received in the shaft 6 and designed as a pneumatic rotary drive.
- the wave 6 is for this purpose as a hollow shaft with different chambers designed via connections 19 pneumatically or hydraulically be charged.
