Description
Technical field
The utility model belongs to cement industry milling equipment technical field, and in particular to a kind of rotary feeder.
Background technology
Currently, the drawing-in device of domestic dry cement production line mainly separates tri- pneumatic air valves of Lun He using rotation.
But in actual use, rotation separates wheel and has the following problems：If convey high humidity/viscous material, material be easily adhered
Separate on wheel, if do not cleared up in time, these materials will be hardened, causes blocking, causes continuous production poor, shadow
Ring the running efficiency of whole production line.
In order to solve this problem, the Chinese invention patent of Patent No. CN201110213727.4 discloses a kind of vertical
Roller grinds rotary feeder, which includes shell, and shell has the shell side plate of shell arc plate and end, shell top
Equipped with feed inlet, it is equipped with discharge port below shell, variable frequency reducer motor, variable frequency reducer motor and center are additionally provided with outside the shell
Axis connection, central shaft are mounted on by bearing in shell, and central shaft is equipped with impeller by axle sleeve, and impeller has along central shaft
The blade radially extended, blade are divided into multiple hopper chambers by the space uniform in shell；The surface of blade is equipped with blade
Wearing plate, blade wearing plate are mounted on by bolt on blade；Impeller is equipped with shell side guard plate, and shell side guard plate is located at blade
Both ends and perpendicular to central shaft, the region between blade is isolated shell side guard plate with shell side plate；Opposite shell side plate
On be additionally provided with fixed into hot blast pipe and hot air duct, can provide hot wind into same hopper chamber into hot blast pipe and hot air duct,
It is also opposite on two blocks of shell side guard plates to offer hot wind through-hole.
The rotary feeder, can be real in the blanking process of high humidity/viscous material by passing to hot wind inside housings
Now not blocking, not sizing.The action principle of hot wind is that the environment of a warm is built in shell, avoids viscous material in blanking
Cause temperature of charge to be lower because ice-cold separation wheel is touched in the process, mobility becomes smaller and separate generate between wheel it is viscous
Even.But this structure can not only increase the energy consumption of rotary feeder, but also only by hopper indoor material when housing bottom
Just there is the chance of whereabouts, but constantly rotated due to separating wheel, each hopper chamber is shorter in housing bottom residence time, and locates
Time in other positions of shell is longer, this results in the material in hopper chamber bottom to leave the limited time of hopper chamber, when
Between it is long, hopper chamber bottoms material is gradually accumulated, and will also result in blocking.
Utility model content
This application provides a kind of rotary feeder, which can effectively prevent solid accumulation in hopper chamber
It is interior.
