Technical Field

[0001] This utility model relates to the field of low-carbon composite cementitious material production technology, and in particular to a raw material drying device for low-carbon composite cementitious materials. Background Technology

[0002] Low-carbon cementitious materials are energy-efficient and environmentally friendly building materials that can replace traditional silicate cement. They use industrial solid waste as raw materials, such as tailings, slag, steel slag, desulfurized gypsum, and fly ash. After specific processing, they exhibit excellent mechanical properties and durability, such as silica-alumina low-carbon composite cementitious materials.

[0003] When treating industrial solid waste, it is necessary to dry it to a constant weight. However, existing drying equipment has low drying efficiency because the drying gas does not come into sufficient contact with the industrial solid waste. Utility Model Content

One end of the dispersing plate is fixed on the left inner wall of the drying drum, and the other end is fixed on the right inner wall of the drying drum.

[0009] A feed pipe is provided at the top of the drying drum.

[0010] As an improvement: the air outlet pipe is rotatably installed inside the drying bracket, and a first electric valve and an exhaust pipe are arranged sequentially from left to right on the air outlet pipe, and a filter screen is installed inside the exhaust pipe.

[0011] As an improvement: a transmission support frame is provided on the left side of the drying rack, and a transmission motor is horizontally mounted on the transmission support frame. The rotor of the transmission motor is fixedly connected to the air outlet pipe.

[0012] As an improvement: the left side of the drying bracket is hinged to a support frame, and the right side is hinged to a telescopic cylinder, which is rotatably disposed inside the support frame.

[0013] As an improvement, a second electric valve is provided on the feed pipe.
