Description

Bran screening machine with automatic chaff cleaning function

Technical Field

The utility model relates to the technology of auxiliary equipment for brewing white spirit, in particular to a bran sieving machine with automatic rice husk cleaning function.

Background

Before white spirit brewing, the husk of the grains needs to be separated and screened out, and a bran screening machine is usually used for completing the step. In the bran screening machine, grains and chaff are separated and then fall onto a screen belt with holes, the chaff is generally crushed into powder or flakes with smaller diameter in the process of separating the chaff from the grains, the grains stay on the surface of the screen belt in the process of rotating the screen belt and are then conveyed to the outlet of the bran screening machine to be collected, and the powder or flakes of the scraps fall into a scraps collecting box through the holes in the screen belt. The chip collecting box is generally welded directly at the bottom of the bran sieving machine, namely below the sieving belt, is funnel-shaped, and is generally opened at the side wall or the eccentric side of the bottom of the chip collecting box, so that the chip collecting box is convenient for manually unpacking and removing chips. However, as the bran screening machine is large in running power and long in running time, scraps are easy to vibrate to be piled up or even agglomerate in the scraps collecting box, if scraps are not cleaned in a short time, scraps can be blocked in the scraps collecting box, and even the scraps are reversely extruded to screen belts or blocked in gaps of parts such as bearings, so that the bran screening machine is damaged. Moreover, because the body of the bran sieving machine is large, the manual scrap removing can not reach all corners in the scrap collecting box, and the manual scrap removing also needs to be stopped. For example, a typical bran screening machine with a screen belt of 5 meters length can generate 1 ton or more of chaff scraps after 2 hours of operation, and the chaff scraps are difficult and physically demanding to clean at one time. Therefore, the existing bran sieving machine has the defects of low dust removing efficiency and incomplete dust removing, and the work efficiency of the bran sieving machine is affected and even the bran sieving machine is easy to damage.

For this reason, it is necessary to design a bran machine with an automatic cleaning of the chaff.
