Description

Anti-bridging device of flour bin

Technical Field

The utility model belongs to the technical field of flour production facility, concretely relates to device that prevents bridging of flour feed bin.

Background

In the later stage of flour processing, prepared flour is generally conveyed into a storage bin by a lifting machine and then packaged by a packaging machine arranged at the bottom of the storage bin. The packing bin generally needs a larger volume, but the outlet cannot be too large, so that the flour at the lower part of the bin can be layered due to the reasons of the flour molecular spacing and the like, cavities exist among layers, namely, flour exists in some places along the vertical direction, flour does not exist in some places, and the phenomenon is called 'bridging' in the industry. The adverse effect caused by bridging is that flour blanking is not uniform, and subsequent packaging control is influenced. CN 105600194A discloses an anti-bridging device of flour feed bin, set up a rectangle housing at feed bin toper outer wall, the opening of rectangle housing is covered and is had the canvas, the canvas constitutes the air cavity with the rectangle housing, be equipped with the trachea on the conch wall of rectangle housing, the toper lateral wall of feed bin is equipped with the rectangular opening, the canvas corresponds the cooperation with the rectangular opening, let in the compressed gas in to the rectangle housing through the trachea, the compressed gas makes the canvas vibrate, the canvas of vibration extrudees the flour in the feed bin, avoid bridging phenomenon. The device is because the canvas directly carries out the face contact with flour, and pressure is little, and the canvas has also blockked that compressed gas gets into the feed bin, and it is less that flour receives to assault violently, consequently can not produce the bridging phenomenon again at the flour in the feed bin relative with the canvas is positive, nevertheless, at the flour in the feed bin relative with the canvas is non-positive, the bridging phenomenon still exists.
