The bottom of cylinder is set to inverted cone, can be so that discharging or material enter feed back cylinder by feed back pipe, to reduce in material storage tube
Salvage stores.
Preferred version two: based on the further optimization of scheme, the diameter of described supervisor is more than the diameter of arm;When propping up
When the diameter of pipe is less, after material enters supervisor, the ratio that material mixes with air will reduce, and therefore can improve in supervisor
The flow velocity of air-flow so that the negative pressure formed in feed back cylinder be enough to suck in supervisor, simultaneously because material mixes with air by material
Ratio relatively low, therefore the mobility of material is higher, so the mixing of more conducively material.
Preferred version three: based on the further optimization of scheme, described feed back pipe is connected to the upper end of feed back cylinder, described
The arm of feed pipe is connected to the lower end of feed back cylinder;Feed back pipe is connected to the upper end beneficially material of feed back cylinder and enters into feed back cylinder
