Description

Additive adding device of concrete mixing plant

Technical Field

The utility model relates to the technical field of concrete mixing stations, in particular to an additive adding device of a concrete mixing station.

Background

Concrete is a general term for engineering composite materials which are formed by integrating aggregates by cementing materials, generally cement is used as the cementing materials, sand and stone are used as the aggregates, and a certain proportion of water is added, so that the cement concrete obtained by stirring is widely applied to the civil engineering of buildings.

The concrete mixing plant is a combined device for intensively mixing concrete, and is commonly used for large-scale and medium-scale water conservancy projects, power projects, bridges and other projects with large concrete engineering quantity, long construction period and concentrated construction sites. With the development of industrial construction, the stirring station for intensively stirring and providing commodity concrete has great superiority, so the stirring station is rapidly developed, and conditions are created for popularizing concrete pumping construction to realize the combined operation of stirring, conveying and pouring machinery.

The concrete admixture is a substance which is added for improving and adjusting the performance of concrete, and in recent years, the application of the concrete admixture in engineering is more and more emphasized, and the addition of the concrete admixture plays a certain role in improving the performance of concrete.

The concrete stirring is an operation method for uniformly stirring cement, lime, water and other materials after mixing. Concrete mixing is divided into two types: manually stirring and mechanically stirring the water. The concrete mixing plant is widely applied to construction projects such as industries, agriculture, traffic, national defense, water conservancy and municipal works in China, and the demand is continuously increasing.

At present, most of additives for improving the comprehensive performance of concrete are in a liquid state in the process of producing the concrete in a concrete mixing plant; in the process of stirring concrete, the additive has some defects, for example, after the liquid additive is added into the stirring cylinder, the liquid additive is not easy to uniformly disperse on the surface of the concrete, so that the additive cannot be fully mixed with the concrete, the performance of the concrete is not improved, in addition, the additive is not filtered in the process of adding, the coagulated additive is easy to enter the stirring cylinder, and the mixing contact between the additive and the concrete is affected. Therefore, there is a need for an admixture adding apparatus for a concrete mixing plant that can sufficiently spray liquid admixture onto the surface of concrete and sufficiently mix the admixture with each other, and filter the admixture.

For example, the prior patent publication CN215619119U provides an admixture adding apparatus for a concrete mixing plant, which drives a semi-cone cover to be attached to the inner wall of a mixing bin by a driving motor on a mounting cover, then a hydraulic push rod pushes the semi-cone cover to be embedded into concrete at the edge, then a second water stop valve is opened to enable the admixture in the second conduit to be injected into the inner side of the semi-cone cover through a water supply nozzle, then the driving motor drives each semi-cone cover to rotate towards the side far from the inner wall of the mixing bin, thereby facilitating the semi-cone cover to stir the concrete, and facilitating the admixture to permeate into the inner side of the concrete at the edge, thereby facilitating the mixing of the admixture and the concrete.

However, the device is only suitable for facilitating the penetration of the admixture into the concrete at the edges, and the liquid admixture cannot be sufficiently sprayed on the concrete surface and sufficiently mixed with each other, and the admixture is not filtered.

The existing additive adding device of the concrete mixing plant is difficult to uniformly disperse on the surface of concrete after the liquid additive is added into the mixing cylinder, so that the additive cannot be fully mixed with the concrete, the performance of the concrete is not improved, the additive is not filtered in the adding process, and the coagulated additive is easy to enter the mixing cylinder to influence the mixing contact between the additive and the concrete.
