Description
Technical Field
The utility model belongs to the technical field of fly ash production facility, concretely relates to fly ash V type selection powder machine.
Background
Fly ash, a fine solid particulate in the ash of flue gases produced by the combustion of fuels. Such as fine ash collected from flue gases from coal fired power plants. The fly ash is formed by cooling pulverized coal after entering a hearth at 1300-1500 ℃ and being subjected to heat absorption by a hot surface under the suspension combustion condition. The mechanical property and durability of the track slab concrete can be obviously improved by adding the fly ash.
In the production process of the fly ash, the wet fly ash needs to be dried to remove moisture in the wet fly ash, so that the influence of the moisture in the wet fly ash on subsequent operation is avoided, meanwhile, after the fly ash is crushed for 1 time, part of crushed materials reach the fine powder level, and can be directly put into fine grinding, so that the crushed materials are screened out in advance before further crushing, the crushing energy consumption is reduced, and the production efficiency is improved; however, moisture carried by the fly ash can cause particle cohesion and thus be detrimental to fine-grade fly ash separation.
SUMMERY OF THE UTILITY MODEL
To current fly ash because the problem that is difficult to separate and sieves that carries moisture and leads to, the utility model provides a fly ash V type selection powder machine, this fly ash V type selection powder machine can effectively dry the powder and select wherein farine, improves screening efficiency.
The utility model discloses a fly ash V type selection powder machine, including collecting chamber, discharging pipe, inlet pipe, outlet duct, V die cavity, intake pipe, heating device and fan, the inlet pipe with the discharging pipe connect in the top of V die cavity, just the inlet pipe is located the below of discharging pipe, be provided with first filter screen in the V die cavity, first filter screen is located the discharging pipe with between the inlet pipe, the discharging pipe intercommunication collect the chamber, the outlet duct is located collect the top and the intercommunication in chamber collect the chamber, be provided with second filter screen in the outlet duct, intake-tube connection in the bottom of V die cavity, heating device with the fan is located in the intake pipe, the bottom of V die cavity is provided with the discharge gate, be provided with control flap on the discharge gate.
Furthermore, first filter screen is the level setting, in order will V die cavity separates and forms former material chamber and ejection of compact chamber, former material chamber is located first filter screen's bottom, the ejection of compact chamber is located first filter screen's top.
Furthermore, the heating device is a resistance wire heating device, and the heating device is positioned between the fan and the V-shaped cavity.
When the fly ash V-shaped powder concentrator is used for screening the fly ash fine powder, the raw material can be guided into the V-shaped cavity through the feeding pipe, hot air is guided from the bottom of the raw material through the air inlet pipe, on one hand, the fly ash raw material can be dried through the flowing of the hot air, and the separation of the fine powder from the surface of large particles is ensured; on the other hand can take away the fine powder in the fly ash raw materials via the discharging pipe gets into collect in the collection chamber, first screen cloth can avoid the too big fly ash of specification to enter into collect in the chamber, this fly ash V type selection powder machine has effectively improved the efficiency of fine powder screening and has improved the screening effect.
