Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a proportioning device for concrete admixtures. Background Art

[0002] Concrete admixtures are active powder materials added to the concrete mixing process. These materials are primarily composed of one or more oxides, such as aluminum, silicon, and calcium, and have a specified fineness to improve concrete properties. Mineral admixtures, along with Portland cement, form the cementitious material, known as supplementary cementitious materials abroad. During the concrete mixing process, admixtures are added to the stirred concrete using proportioning equipment.

[0003] For example, the existing document CN221232827U proposes a concrete mixing device, which includes a feeding barrel, a mixing barrel and a body support. The feeding barrel is arranged on the mixing barrel, and the mixing barrel is installed and fixed on the body support. A driving motor is fixed on the top of the mixing barrel. The device can be used to mix concrete and modified materials to realize the production of concrete admixtures.

[0004] Although the above-mentioned device can achieve mixing, it is not convenient to proportion the added modified materials, so that manual proportioning is required during use. Although there are some mixing devices with proportioning functions in the prior art, such as the prior art CN217046938U proposed a tungsten tailings concrete admixture mixing device with adjustable proportions, the device uses weighing to proportion the mixing ratio of the modified materials. Although this method can also complete the proportioning work, it requires weighing the weight of the modified materials one by one, the adding process is cumbersome, and the proportioning time is long. In response to the above problems, we provide a concrete admixture proportioning device to solve the problems existing in the prior art. Utility Model Content
