Device for the pneumatic discharge of bulk material from containers

The invention relates to a pneumatic device for discharging products from Sohüttgutcontainer with flat distribution a gas chiohi on the inside wall of the container,

With such ventilation devices, powdery, dusty, granular or chipped bulk goods, especially those that are difficult to flow and bake, tend to form bridges and stick to the wall, are brought to flow out of an opening located on the bottom of the container, preferably at the end of a cone siote _e

The advantages achieved with the invention are in particular that with a minimum of material and processing and low gas supply, even the most difficult products are permissible to slide off the wall and to flow out of the Container can be brought. In addition, the entire product in the container can be ventilated by excessive gas supply or pre-homogenized.

The invention is illustrated in the drawing and will be described in more detail below. Show it

Fig. L) a basic arrangement of the invention. Here are the individual discharge elements distributed so that each one fliiohennä'ulg gleiofa largest piece of the inner wall of the container is assigned (uniform overlap of the area of action). The compressed gas is supplied to the individual support elements from the outside.

Fi «. 2) a similar arrangement with compressed gas supply via the Inside of the container.

Fig. 3) a special embodiment of a discharge element, consisting of gas supply part (1) and gas deflection part (2). Here, the opening (3) for the gas outlet is made so that on the edge of the shell-shaped design, the Sasumltnktcilss are attached to the - when the long screw (5) is tightened. Place the container wall (6) and adapt the shell · to the contour of the wall «
