Efficient mixing device

Abstract

The invention relates to an efficient mixing device, which is characterized in that a feeding hopper is arranged at the upper part of one end of a round mixing barrel, and a discharging port is formed in the lower part of the other end of the round mixing barrel; a rotating shaft is axially arranged in the mixing barrel, and a rotating frame which axially rotates in the direction opposite to the rotating direction of the rotating shaft is arranged in the mixing barrel; the rotating shaft 7 is connected with a plurality of shaft stirring blades, and the rotating frame is connected with a plurality of frame stirring blades. The efficient mixing device provided by the invention overcomes the defects that the efficiency is low, the mixing cost is high, the mixing uniformity is difficult to meet the technical requirements and the like. The efficient mixing device provided by the invention has the advantages that the feeding, mixing and discharging are continuously carried out in the whole mixing process, the efficiency is very high, and the mixing uniformity is very good; meanwhile the operation is also completed in one time for several kinds of mixtures, and a part of or all of the blade surfaces of the shaft stirring blades and the frame stirring blades as well as the axial direction of the mixing barrel have a certain included angle to form a rotating spiral structure, so that the mixture in the mixing barrel is pushed in the direction of the discharge port while being mixed, and is discharged out of the discharging port after being fully mixed.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a high-efficiency mixing device. Background technique [0002] Before the present invention is made, it is often encountered in engineering construction that various materials need to be added to the underground soil for mixing, and the mixing amount is often still very large. Existing conventional technology can only simply adopt an excavator to excavate, then sprinkle the designed mixing material into the excavated soil body, and use the excavator grab bucket to repeatedly mix. It is conceivable that such efficiency is very low, and the degree of mixing cannot be very uniform. As a large number of contaminated soil layers need to be treated, the simplest and most effective treatment method is to add suitable chemical materials to the contaminated soil layers to be treated for neutralization or solidification reaction, thus facing a large number of mixing operations.

Problems solved by technology

Therefore, the original mixing method can no longer meet the requirements, seriously restricting the progress of contaminated soil treatment

The treatment of contaminated soil is inseparable from mixing. The main problem of mixing technology is the uniformity of mixing efficiency and mixing quality. The mixing equipment available in the market is very inefficient if the mixing quality can meet the requirements. , so that the mixing cost is very high, which cannot meet the demand. Furthermore, it is a simple excavator for excavation and mixing. With this mixing method, although the mixing efficiency is improved to a certain extent, the mixing uniformity is difficult to meet the technical requirements.
