Description

A feed bin for powder ejection of compact

Technical Field

The utility model belongs to the technical field of the unloading mechanism, concretely relates to lower feed bin for the powder ejection of compact.

Background

In the blanking of the bin body, the powder can adopt integral flow or central flow in the flowing process.

By central flow is meant that during discharge, the powder particles mainly flow through the center of the vessel, above the outlet, while material remains on both sides of the vessel, causing particle rolling and separation of the mixture. Therefore, the materials are easy to be clamped and are not beneficial to be discharged from the storage bin.

The bulk flow means that all the powder moves in the container during the blanking. The whole flow generates a first-in first-out flow sequence, powder accumulation and dead angles are avoided, and the blanking is more stable, more uniform and more controlled.

The existing blanking bins mostly adopt a sliding plate valve and a butterfly valve bin to form central flow, which causes the defects, and in addition, another problem of the butterfly valve or the sliding plate valve bin is the problem called arching or bridging. Differences in the size, shape and density of the powder in the mixture can cause the materials to lock or stick together, forming an "arch" over the outlet of the container. If any powder above the outlet is bonded together to form an arched bridge, the powder cannot escape, the powder flow stops, and the powder can be discharged only in a manual knocking mode.

Therefore, a blanking silo capable of generating overall flow is provided, so as to avoid the above disadvantages.
