Mixing cabin and mixing apparatus

Abstract

The invention relates to the technical field of mixing of various particulate materials, in particular to a mixing chamber, comprising a mixing chamber body that is of inverted cone structure provided with an upper opening and a discharge port in the lower portion; the mixing chamber body comprises a circular inner wall, the middle of the inner wall is provided with a discharge annular face, and at least the discharge annular face is a hyperbolic annular face or a parabolic annular face. The invention also discloses a mixing apparatus, comprising the mixing chamber mentioned above, and also comprising a support and a plurality of quantitative feeding devices arranged above the mixing chamber, each quantitative feeding device comprises a feeding outlet provided with a dropping guide plate, a guide extension line of each dropping guide plate points to another focal point of the hyperbolic annular face, and a guide direction of each dropping guide plate is parallel to the axis of the parabolic annular face. The mixing chamber and the mixing apparatus have the advantages that various materials can be mixed well, and damage of particles due to stirring is avoided.

Description

technical field [0001] The invention relates to the technical field of mixing various granular materials, in particular to a mixing bin and a mixing device. Background technique [0002] In many fields, two or more materials need to be thoroughly mixed to obtain admixtures. Taking the preparation of BB fertilizer (Bulkblending fertilizer, the full name is bulk blending fertilizer) as an example, at present, nitrogen, phosphorus, potassium and some auxiliary materials are weighed according to a certain ratio and then sent to a mixer mainly for mixing for mixing. It is a variety of fertilizers that can be fully mixed according to the proportion, and fertilized accurately, so as to obtain better fertilization effect. Since the proportions of nitrogen, phosphorus, potassium and some auxiliary materials are accurately calculated according to soil testing and fertilizer matching, after the theoretical ratio is guaranteed, whether the mixing can be ensured is a key process to ensu...

AI Technical Summary

Problems solved by technology

However, the main defect of the above-mentioned mixing device is that several kinds of fertilizers need to be rotated and stirred repeatedly, which easily causes the fertilizer particles to be broken. When fully mixed, the fertilizer particles have been refined or broken, thereby reducing the fertilization effect.

[0004] In addition, the traditional fertilizer dispensing machine also measures several kinds of fertilizers separately and then puts them together, and then mixes them uniformly. In addition to the above defects, the fertilizer distributing efficiency of this method is also very low
