Embodiment 1

[0034] Such as figure 1 , 2 , 3, 4, 5, 6, 7, and 8, a single-shaft screw mixer includes a mixing bin body 1, a mixing shaft 2 in the mixing bin body, a feed port and a discharge port, and the Both ends of the mixing shaft 2 are supported by bearing components such as bearings and bearing seats. The power components of the mixing machine are a motor 8, a reducer 9 and a shaft coupling 10, and the reducer 9 is a cycloidal pinwheel reducer; The upper part of the mixing bin body 1 is provided with a primary bin 11, and the primary bin 11 is connected to the mixing bin body 1 through a feed port; the mixing shaft 2 is welded with 4 rows of criss-cross ribbon support columns 7 respectively. , the top of the ribbon support column 7 is provided with a spiral reamer 5, while the ribbon support column 7 is supporting the spiral reamer 5, the ribbon support column 7 is also equipped with criss-cross shattering shaft blocks 6, the spiral The reamer 5 is divided into a left helical reame...

Embodiment 2

[0040] Such as Figure 9 , 10, Shown in 11 and 12, a kind of uniaxial screw mixer, different from the above-mentioned embodiment is not installed on the ribbon support column 7 to break up the shaft block 6, the above-mentioned spiral reamer 5 on the ribbon support column 7 The inner layer spiral reamer 18 is installed inside, the inner layer spiral reamer 18 on the same ribbon support column 7 forms a cross shape with the spiral reamer 5, and the inner layer spiral reamer 18 on the same ribbon support column 7 The blade of the spiral reamer 5 rotates in the opposite direction (for example, the blade of the left spiral reamer rotates to the left end, then the inner spiral reamer on the ribbon support column corresponding to the left spiral reamer rotates to the right end), The inner spiral reamer 18 and the spiral reamer 5 are connected in a cross shape by the ribbon support column 7. With the reverse rotation of the mixing shaft 2, due to the effect of countercurrent, the mo...

Abstract

The invention relates to a single-shaft spiral mixer which comprises a power assembly, a mixing bin body, a feeding hole formed in the upper part of the mixing bin body, and a discharging hole formed in the bottom of the mixing bin body, wherein two ends of a mixing shaft are supported by bearings and bearing seats, the mixing shaft is connected with a coupler through a bearing, a primary bin is arranged at the upper part of the mixing bin body and is connected with the mixing bin body through the feeding hole, the mixing shaft is a single spiral shaft, alternated spiral ribbon support columns are fixedly arranged on the single spiral shaft, spiral reamers are arranged on the top ends of the spiral ribbon support columns, spiral directions of blades of the spiral reamers at the left side and the right side of the mixing shaft are opposite, and the blades of the spiral reamers at the left side and the right side of the mixing shaft rotate towards the center of the mixing shaft for pushing materials to the middle of the mixing shaft. The single-shaft spiral mixer disclosed by the invention has the advantages that the materials are pushed towards the middle of the mixing shaft by adopting the spiral reamers with opposite rotating directions, the dispersing and mixing efficiency is high, and the feeding and the discharging are automatically controlled.

Description

technical field [0001] The invention relates to the field of material mixing, in particular to a single-shaft screw mixer. Background technique [0002] The mixing of materials is a very important link in the material processing and logistics industry. Uneven mixing of materials not only leads to unsatisfactory mixing and batching effects, but also causes waste of resources. Traditional mixers mostly adopt the form of double-shaft single-helical reamers, which have a long mixing period, low mixing uniformity, large power, large external volume, and uncompact structure. The mixing effect for larger materials is not good, and the feeding and discharging The materials are all manually controlled, it is difficult to achieve precise control, and the degree of automation is low, resulting in low production efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of low mixing uniformity, long mixing cycle, poor mixing ...
