Abstract

Pulp distributor for the selective metering of fiber-containing conveying materials for pneumatic conveying systems, characterized in that the conveying material is braked and swirled in the closed tube (4).

Description

According to the current state of the art, fibrous materials can be conveyed to their destination using pneumatic conveyor systems in various ways. Long-fiber conveying materials such as straw or hay can be blown freely to a destination. With this method, however, there is a very high degree of variation. It is therefore not possible to determine an exact point target point for the conveying materials. Only in the case of short-fiber, moist substances, such as corn silage, can a cyclone ensure that the substances are dosed at specific points. The selection of the materials to be conveyed is manageable for the plant operator, however, since long-fiber materials cannot be dosed via a cyclone, as the material accumulates in the cyclone and the cyclone outlet clogs accordingly.

This problem is solved with the aid of the invention of the pulp distributor.

The pulp distributor applies to every fiber-containing conveying material, regardless of whether it is long or short-fiber - regardless of whether it is damp or dry. In this way, the system operator can be given a wide range of materials to choose from and a change between different materials can be ensured without any problems. So this is possible with one and the same distributor.

About admission (1) a machine-generated air stream, on which the conveyed material is transported, is blown into the distributor. The fibrous conveying material (2) is transported to the closed pipe via the air flow (4) . The excess air goes through an outlet (3) lost. The material to be conveyed is carried further into the closed pipe via the momentum (4) emotional. In this, the conveyed material bounces off the opposite wall, swirls, decelerates due to the impact against the pipe wall and falls down exactly over the outlet for the fibrous conveyed material (5) to the target point.

The pulp distributor was mainly developed for the agricultural sector, but can also be used in industry. In agriculture, the system can be used in an existing stable and supply the animals in the pen with raw fiber, which is used for the animal welfare of the animals. In this case, the raw fiber material, such as straw or maize silage, is dosed via a mixing station onto a machine-generated air flow, which is used to move the material to the target point. At the target point, as in the description above, the material falls onto a closed surface or a feeding table. The animals can then eat the raw fiber material offered.
