According to the utility model, the compressed air nozzle is arranged at the discharging opening of the powder proportioning device, and air is intermittently sprayed at fixed intervals in the discharging process, so that the powder material can be effectively prevented from accumulating on the wall of the discharging opening, and the probability of blocking the powder material is reduced. If the blockage occurs, the air can be continuously injected to blow away the accumulated powdery materials for dredging.

Description

Concrete stirring and batching device

Technical Field

The utility model belongs to the technical field of concrete stirring, and particularly relates to a concrete stirring and proportioning device.

Background

Concrete refers to a generic term for engineering composite materials in which aggregate is consolidated into a whole by a cementitious material. The term concrete generally refers to cement as a cementing material, sand and stone as aggregate; the cement concrete, also called ordinary concrete, obtained by mixing the cement concrete with water (which can contain additives and admixtures) according to a certain proportion is widely applied to civil engineering.

In the stirring process, powdery materials such as cement and the like are easy to adhere and accumulate on the side wall of a discharging opening due to the discharging characteristics of the powdery materials, and when the powdery materials are accumulated to a certain degree, the phenomenon of blocking easily occurs, so that the discharging is not smooth. In the prior art, equipment such as a screw feeder is adopted to assist the powder proportioning device in blanking, but a blocking phenomenon still occurs. The dredging needs to be stopped after blocking, and the engineering progress is greatly influenced.

Like the chinese patent of utility model "a be applied to reinforced pull throughs of concrete mixing plant", publication number CN217346070U, including the storage tank, the storage tank is fixed mounting on the mount, and mount fixed connection is on ground basis, and the lower extreme of storage tank discharge gate is provided with screw conveyor, and screw conveyor's discharge gate is connected with weighing device, and weighing device's discharge gate is connected with horizontal mixer, and horizontal mixer is fixed mounting in the top of mounting bracket, and the bottom of mounting bracket is fixed connection on ground basis, and horizontal mixer's discharge gate is connected with the finished product storehouse. This be applied to reinforced pull throughs of concrete mixing plant through setting up stirring device and velocity of flow detection device, can dredge the material according to different velocity of flow sizes to the discharge gate, avoids the lower extreme of the discharge gate that the powder piled up under the effect of gravity, and the discharge gate that causes blocks up, sets up two simultaneously and accelerates unloading rate, improves device conveying efficiency. According to the technology, a mechanical stirring device is arranged at a discharging opening, and a flow speed detection device is combined, so that the rigidity of the discharging opening is dredged through mechanical stirring.

For another example, in the chinese patent application, "a material adding, stirring and conveying device for preparing concrete", publication No. CN115351923a, a stirrer and at least three material tanks, a material outlet of each material tank is provided with a material blocking preventing screw conveying device, and a material outlet of each material blocking preventing screw conveying device is connected to the stirrer; the screw conveying device is not blocked, and the normal operation of the stirring station is not influenced; be equipped with dedicated belt cleaning device in the head tank, labour saving and time saving when wasing the inside of head tank. According to the technical scheme, the purpose of blocking prevention is achieved by arranging a plurality of groups of spiral conveying mechanisms in the raw material tank and the conveying pipe and adopting the Y-shaped collecting pipe. Although the prior art provides various anti-blocking technical schemes, most of the anti-blocking devices adopt mechanical structural rigidity to dredge and prevent blocking, have complex structures, higher use and maintenance cost and are difficult to reform on the prior equipment.
