Description

Technical Field

[0001] The invention relates to the technical field of material conveying, in particular to a flow-aiding device for conveying flocculent materials in a cone-bottomed bin. Background Art

[0002] Cone-bottom silos are widely used in grain, oil, food, feed, chemical, metallurgy, building materials and other industries. The silos mainly store solid block or powder materials, and the natural inclination of the conical surface of the silo bottom allows the materials in the silo to flow out naturally by their own weight. However, when flocculent materials such as cotton, paper strips, and hair are stored in the silo, the flocculent materials themselves are light in weight, which makes it difficult for the flocculent materials to flow out naturally from the silo. Therefore, a flow-aiding device for conveying flocculent materials in cone-bottom silos is needed to enable the flocculent materials to flow out stably. Summary of the invention

[0003] The present invention aims to solve the above-mentioned problem, thereby providing a flow-aiding device for conveying flocculent materials in a conical bottom bin.

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution:

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0007] The invention has a simple structure and low manufacturing cost. The power unit drives the flow-aiding rod to reciprocate up and down. When the flow-aiding rod moves upward, the flow-aiding plate is recovered into the vertical groove under the action of its own gravity and the extrusion of the material to prevent the material from being lifted up during the upward movement. When the flow-aiding rod moves downward, the flow-aiding plate will be expanded by the material. After the flow-aiding plate is expanded, the area of ​​action with the material is increased. The material will move downward under the action of the flow-aiding rod and be smoothly discharged from the cone bottom bin. The flow-aiding effect is more obvious and the practicability is strong.
