Description

Blender to mix well

technical field

The invention relates to the field of building construction equipment, in particular to a mixer for uniform mixing.

Background technique

Cement slurry is required for building block gap construction and prestressed concrete pouring construction. The requirements for this type of cement slurry are relatively high. In addition to meeting a certain water-cement ratio, the cement slurry for the block gap and the pouring cement slurry must be mixed evenly. Generally, the existing cement mixer is composed of a motor, a feed inlet, a slurry outlet, etc. on the mixing drum. The motor is connected to the vertical shaft in the mixing drum, and the vertical shaft is provided with stirring blades. For example, the Chinese patent "a cement mixer" with the authorized announcement number CN 203579879 U discloses a cement mixer, including a mixing bucket, a cover plate is provided on the mixing bucket, and a chute is provided on the cover plate. , A track is provided between the cover plate and the mixing bucket, a pulley is provided in the track, and a bracket is provided under the mixing bucket. The utility model is simple in structure and ingenious in design. During the stirring process, the stirring blades can move back and forth, and the stirring barrel can also move up and down, so that the stirring is even. In this way, not only the structure is simple, the operation is convenient, but also the efficiency is high.

Another example is the Chinese patent "New Cement Mixer" with the authorized announcement number CN 201012523 Y, which discloses a cement mixer, which includes a mixing drum, a gear shaft and a motor installed on the main frame, and a second gear is provided at one end of the gear shaft. , the other end is connected to the motor fixed on the main frame through the transmission device, the bottom of the mixing drum is provided with the first gear of the second gear meshing transmission, the shaft of the mixing drum is inclined to the gear shaft, and connected to the gear shaft through the rotating device . The mixing drum of the utility model can rotate on its own and can also revolve around. There are also a plurality of stirring bars in the mixing drum, so that the cement can be stirred quickly and evenly under the action of various forces.

Although the mixer disclosed above has a simplified structure and a high mixing rate, due to its structural limitations, the mixing blades in the mixing drum have a working blind area in the mixing drum, so that the cement slurry cannot be fully and uniformly stirred, so it cannot meet the construction specifications. requirements. Especially for the mixing operation of thin mortar such as foam concrete, because there is a big difference in the density of the materials in the thin mortar, the material with low density floats on the material with relatively high density, so the blade shape of this type of mixer is difficult to play. The function of tumbling can only be used as a stirring action of circular pushing, so it is difficult for this type of mixer to meet the mixing process requirements.

The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art.
