Segmented mixer with double horizontal shafts

Abstract

The invention discloses a segmented mixer with double horizontal shafts. The segmented mixer comprises a rack, a mixing barrel arranged on the rack, two mixing shafts arranged in the mixing barrel in parallel along the longitudinal direction, a mixing transmission device and a vibration transmission device, wherein the mixing barrel is divided into a vibration mixing chamber with a charge port and a static mixing chamber with a discharge port through a division fixing plate vertical to the axial direction of the mixing barrel; an opening used for communicating the vibration mixing chamber with the static mixing chamber is arranged in the lower part of the division fixing plate; two connection seat installation holes are arranged above the opening of the division fixing plate; a connection seat is fixedly installed at the connection seat installation holes of the division fixing plate; and the mixing shaft comprises a vibration mixing shaft and a static mixing shaft. According to the mixer disclosed by the invention, two main machines for vibration mixing and static mixing in a two-stage mixing system are combined into one piece through the division fixing plate, thus the production cost of the main machines is saved, the mixing time is shortened, and the space occupied by the mixer is reduced.

Description

technical field [0001] The invention belongs to the technical field of mixing equipment, and in particular relates to a segmented twin-shaft mixer. Background technique [0002] The traditional mixer for concrete production can mix the material into uniform concrete that meets the quality requirements in a short time. Compared with manual mixing, it has the advantages of high efficiency, reduced labor intensity and improved mixing quality. It can achieve macroscopic uniformity in a very short time, but microscopic uniformity is not achieved. If the cement slurry of macroscopically uniform concrete after mixing is placed under a microscope, it is found that the cement particles are not evenly dispersed in water, and there are still 10 %-30% of the cement particles gather together in twos and threes to form tiny cement clusters. During the mixing process, because the stirring arm is rotating at a constant speed, the bond formed by the material is continuously accumulated on th...

Problems solved by technology

[0004] There are only two types of stirring shafts used in the existing mixing plants: vibratory stirring and static stirring, and no matter which stirring shaft is used alone, it cannot achieve a better stirring effect. The mixing hosts are simply used in series to form a secondary mixing. Although such a setting can achieve the purpose of mixing, it is cumbersome to operate, complicated in structure and takes up a lot of space.
