Envelope.By the inlet flange at the top of rotary valve, material is introduced into rotary valve.When rotor blade reaches gatehead, material
Because gravity is fallen into unlimited impeller pit.When impeller and material pass through gatehead, the closing of independent pit.When impeller pit
During by unlimited emptying point, material is discharged from the bottom of rotary valve.Under gravity, material is entered by discharging flange
Upstream device.The lock wind discharge valve for the generally single impeller formula applied in workshop, in some easily adhesions, easy caking materials production
When, because long-time operates, it can accumulate material on impeller more and more, so as to influence the efficiency of blanking.
The content of the invention
The purpose of this utility model be solve the difficult cleaning of single impeller formula lock wind discharge valve impeller adhered materials in the prior art,
The low technical problem of efficiency, there is provided a kind of Double-impeller type lock wind discharge valve rational in infrastructure, practical function, to overcome prior art
Deficiency.
To achieve these goals, the utility model is achieved through the following technical solutions：
A kind of Double-impeller type locks wind discharge valve, and it includes housing and motor, and its main points is to be provided with entrance above the housing
Flange, lower section are provided with outlet(discharge) flange；Driving shaft and driven shaft are provided with the housing；The driving shaft is provided with big impeller；Institute
State driven shaft and be provided with small impeller；Lower section between two impeller is provided with one section of arc inner wall；The driving shaft and driven shaft
Both ends are respectively equipped with bearing, and the gear of external toothing is provided with the outside of the bearing of one end；The outermost end of driving shaft is provided with belt wheel I；Motor
It is connected by belt wheel III and belt wheel IV with reduction box；The projecting shaft of reduction box is provided with belt wheel II；The belt wheel I is logical with belt wheel II
Cross belt connection.
As a further improvement, the length of blade of the small impeller is 30-40cm, the length of blade of big impeller is 50-
60cm。
As a further improvement, the vane tip of the small impeller is in hook-shaped.
As a further improvement, the radian of the arc inner wall is more than the radian between two adjacent blades.
The utility model is improved to Double-impeller type according to the characteristics of rotary valve, by single impeller formula, passes through the gear of external toothing
Two impellers are interlocked, wherein the blade of small impeller extend into the impeller clearance of big impeller just, so in operation process, two leaves
Wheel engagement operation, and the blade outer end of small impeller is in hook formation all the time, can also be mutually while constantly rotation discharging
Cleaning to blade, prevent adhered materials.The utility model discharges from both ends, than the material of single impeller formula lock wind discharge valve
Throughput is bigger, and the efficiency of discharging effectively improves, and equipment operation is also relatively steady.In addition, in order to keep preferably locking wind
Property, this is provided with arc inner wall using the new lower section between two impellers.Impeller blade by matching somebody with somebody herein closely with arc inner wall
Close, form closing.The radian of arc inner wall is more than the radian between impeller adjacent blades, so when a blade is left in arc
During wall, next blade just enters arc inner wall and forms closing.The utility model practical function, rational in infrastructure, effective solution
Single impeller formula in the prior art of having determined locks the technical problem that wind discharge valve thruput is lacked and impeller adhered materials are not easily cleaned.
