Combined gravity mixing bin

Abstract

The utility model discloses a combined gravity mixing bin which comprises a primary storage unit, a secondary storage unit, a pneumatic valve and a mixing bin, according to the scheme, external circulating material mixing is not needed, energy consumption can be reduced, material crushing is reduced, and the situation that quality is affected by dust, wiredrawing and the like is reduced. And 64 batches of materials can be uniformly mixed. According to the scheme, the stock bin is composed of the two storage stock bin bodies and the mixing stock bin body, and the partition plates are arranged to be in an arc shape, so that large material pressure can be borne under the condition that materials are saved; a rotating mechanism of the feeding port and the discharging port is accurate in control angle, simple in structure and small in energy consumption, and only compressed air is needed; a central pipe and a partition plate are arranged in each storage bin, blanking and mixing are carried out through a slotted hole in the central pipe, the structure is simple and efficient, and a blocking pipe is driven to control the discharging speed at a discharging port of the central pipe of the first-stage storage bin through stretching and retracting of an air cylinder with an outlet adjusting valve; a baffle and a baffle pipe are arranged in the mixing bin, and mixing is further enhanced through collision and dispersion.
