Description

Novel pipeline concrete mixing system

Technical Field

The utility model relates to a novel pipeline concrete mixing system.

Background

Concrete is usually used in the construction of general ordinary buildings, most of the concrete used in the construction is pre-mixed and used, some of the concrete is prepared by concrete factories and transported to the site by a transport vehicle, and some of the concrete is prepared and mixed on the site and used, and the concrete is pre-mixed before being used, but in some special places, the common concrete injection mode is not very effective.

For example, when an underground dead zone is buried, foam concrete with high accumulation speed, less material consumption, low cost, proper strength and short solidification time is generally used. However, meter-level accumulation can not be carried out on the prior foam concrete without a mold, and the foam concrete flows like water, so that discontinuous pouring is carried out on an underground dead zone by adopting a layered pouring method, namely, a part of foam concrete is poured firstly, and a part of foam concrete is poured after the foam concrete is solidified, and the like. Meanwhile, if the foam concrete prepared by stirring is directly injected into the underground dead zone in batches, the foam concrete in the pipeline is also solidified within the time of waiting for solidification in the middle, so that the blockage of the conveying pipeline is caused, and therefore, a method of mixing foam gel powder and cement slurry in the conveying pipeline in situ needs to be adopted, and a mechanism of injecting and mixing foam concrete is formed.

As shown in fig. 1, a novel pipeline concrete mixing system, including concrete conveying pipe 3 and concrete mixing conveyer pipe 10 that connect gradually, set up booster pump 2 in the concrete conveying pipe 3, set up rotatory impeller 8 in the second concrete conveying pipe 10, rotatory impeller 8 is connected with axis of rotation 6 through rotatory impeller connecting piece 7, and axis of rotation 6 is connected with motor 4's output shaft.

When the underground dead zone is filled, if the foam concrete prepared by stirring is directly injected into the underground dead zone in batches, the foam concrete in the pipeline is also solidified in the middle waiting for solidification, so that the blockage of the conveying pipeline is caused, and therefore, a method of mixing foam gel powder and cement slurry in the conveying pipeline in situ needs to be adopted to form a mechanism of injecting more foam concrete and more foam concrete. Therefore, the novel pipeline concrete stirring system enables concrete to be directly stirred in the conveying pipeline, and the injection mode, the injection amount and the injection time of the concrete can be controlled more flexibly.

Preferably: the adjacent rotary impeller connecting pieces 7 are alternately and vertically arranged.

Preferably: and an arc-shaped rotating impeller 8 is arranged between the adjacent rotating impeller connecting pieces 7.

After concrete mixture 1 gets into concrete conveying pipe 3, utilize booster pump 2 to make concrete mixture 1 flow in iron concrete mixing conveyer pipe 3 fast, open motor 4 and make axis of rotation 6 take up the rotatory impeller 8 fast rotation of iron, make concrete mixture 1 in iron mixing conveyer pipe 3 through the rotatory intensive mixing of the fast rotation of the rotatory impeller 8 of iron to make the concrete carry the in-process preparation of flowing in the pipeline to accomplish. The flowing concrete mixture 1 is stirred directly during the flow in the pipeline and is therefore used directly for casting after passing through the pipeline.

The concrete mixture 1 enters the pipeline concrete mixing system through the concrete conveying pipe 3, and the flow speed of the concrete mixture 1 in the concrete mixing conveying pipe 3 is increased by the booster pump 2.
