Technical Field

[0001] The utility model relates to the technical field of cement ash placing, in particular to a cement ash placing control device. Background Art

[0002] Cement: A powdered hydraulic inorganic cementitious material that becomes a slurry when mixed with water. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime volcanic ash cement. It is used to bond concrete made of crushed stone. After hardening, the concrete not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used in civil construction, water conservancy, national defense and other projects as an important cementitious material.

[0003] A ash placing device is required when transporting bulk cement from a cement tank. The ash placing device can be lifted by a gantry crane to transport cement to any designated location. At the same time, there is very little dust, which is beneficial to the health of workers and improves the efficiency of ash placing. However, the ash placing device only has the function of ash placing. The cement will not fill the inside of the pipeline during transportation, so it is difficult to accurately quantify. For this reason, we propose a ash placing control device for cement. Utility Model Content
