Description

Technical Field

[0001] The utility model relates to the field of vertical shaft pouring, in particular to a flow control device and a pouring system. Background Art

[0002] In the process of developing deep underground mineral resources, shaft engineering is the throat engineering of mines. During the pouring and construction of shafts, the ash pipes may be blocked or fall due to operation, equipment and facilities, which will bring many economic and safety problems to the project. When the concrete is lowered from the surface too fast and the slump is too low, the friction between the concrete and the pipe wall will be too large. If you are not careful, the ash pipes will be blocked and the concrete impact will cause the ash pipes to fall.

[0003] In order to avoid blockage in the ash chute, the traditional method is to install a chute under the mixer and connect it directly to the ash chute. The flow rate and velocity of concrete cannot be effectively controlled, and it is easy to be mixed with large pieces or debris, which can easily cause pipe blockage and concrete segregation. Pipe blockage can easily cause impact on the pipeline, resulting in the risk of pipeline falling and causing serious safety accidents. Utility Model Content

[0012] Furthermore, there are at least two positioning plates, and the positioning plates are arranged in one-to-one correspondence with the diverter plates and are fixedly connected.

[0019] Furthermore, the pouring system also includes an ash storage bucket, the lower end of the ash storage bucket is provided with an ash storage bucket outlet, and the ash storage bucket outlet is located above the ash sliding funnel.

[0020] Furthermore, the pouring system also includes a connecting pipe and a gate valve, one end of the connecting pipe is connected to and communicated with the ash storage bucket outlet, the other end of the connecting pipe is located above the ash hopper, and the gate valve is arranged at one end of the connecting pipe.
