Description

Composite powder mixer

Technical Field

The utility model relates to a combined type powder mixes machine.

Background

Many powdered products are typically made by mixing two or more different powders in proportions. Traditional mixing arrangement adopts a plurality of feed inlets feeding, and many powder get into and mix in the casing, and stirring vane stirs the powder and mixes to convey the material to the exit end in mixing process, the mixing arrangement of this kind of structure, its stirring vane who adopts single soon to more adopts mixes the stirring, and the mixed effect is not very thorough, especially is difficult to reaching its mixed required precision to the higher powder of some fineness requirements.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides a composite powder mixer which can effectively improve the mixing effect.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a combined type powder mixes machine, includes the casing, and casing one end is equipped with two at least inlet pipes, and the casing other end is equipped with the discharging pipe, the casing in be equipped with the (mixing) shaft, install spiral stirring leaf on the (mixing) shaft, the interval is equipped with a plurality of oar blades on the (mixing) shaft of nearly discharging pipe side, oar blade diameter of gyration is less than the diameter of gyration of spiral stirring leaf, the installation length of oar blade on the (mixing) shaft is the third of casing length, the rotation of oar blade is to the opposite with the rotation of spiral stirring leaf.

Furthermore, the stirring shaft is connected with a variable frequency motor through a coupler.

In order to better improve the stirring effect, the inclination angle between the paddle blade and the axis of the stirring shaft is 20 degrees.

Preferably, the rotating diameter of the paddle blade is one half of the rotating diameter of the spiral stirring blade.

The utility model has the advantages that: the utility model discloses a spiral stirring leaf cooperation oar blade mixes the conveying to the stirring of powder forward and reverse to this has improved the mixed effect of powder effectively, has satisfied the requirement of powder mixing precision.

Drawings

The present invention will be further described with reference to the accompanying drawings and embodiments.

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. the device comprises a shell, a feeding pipe 2, a discharging pipe 3, a stirring shaft 4, a spiral stirring blade 5, a paddle blade 6, a coupler 7 and a variable frequency motor 8.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 shows a combined type powder mixer, which comprises a casing 1, wherein one end of the casing 1 is provided with two feeding pipes 2 capable of entering different powders, the other end of the casing 1 is provided with a discharging pipe 3 for discharging mixed powders, a motor support is arranged on the outer side of the casing 1 at one end of the feeding end 2, and a variable frequency motor 8 is fixed on the motor support.

The stirring shaft 4 is arranged in the shell 1, and the stirring shaft 4 is in transmission connection with the variable frequency motor 8 through the coupler 7.

The stirring shaft 4 on install spiral stirring leaf 5, the (mixing) shaft 4 of nearly discharging pipe 3 side is gone up the interval and is equipped with a set of oar blade 6, single oar blade 6 sets up at 5 gyration pitch intermediate positions of spiral stirring leaf, the rotation of oar blade 6 is to opposite with the rotation of spiral stirring leaf 5.

The rotation diameter of the paddle blade 6 is one half of the rotation diameter of the spiral stirring blade 5, the installation length of the paddle blade 6 on the stirring shaft 4 is one third of the length of the shell 1, and the inclination angle between the paddle blade 6 and the axis of the stirring shaft 4 is 20 degrees.

The utility model discloses when mixing, the powder that spiral stirring leaf 5 got into inlet pipe 2 stirs the mixture and conveys to 3 directions of discharging pipe, when the material conveys to the 1 half position of casing, a set of oar blade 6 will produce the mixed action of reverse pushing-type to the powder to cooperation spiral stirring leaf 5 further mixes the powder. However, the rotation diameter of the paddle blade 6 is only one half of the rotation diameter of the spiral stirring blade 5, so the generated reverse thrust is far smaller than the thrust of the spiral stirring blade 5, and after the powder is fully stirred and mixed in the forward and reverse directions, the whole powder is still conveyed towards the discharge pipe 3 under the thrust action of the spiral stirring blade 5, so the mixing effect of the powder is effectively improved, and the requirement on the powder mixing precision is met.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
