Described storage tank discharge nozzle one end is horizontally set on vertical storage tank inner bottom, the other end stretches out outside vertical storage tank and is connected with described conveyer feed pipe, described conveyer feed pipe inside is provided with can rotate and be fixed with the feed pipe stiff shaft of helical blade in pipe, and described feed pipe stiff shaft one end extends to storage tank discharge nozzle inside;
Described discharge nozzle stiff shaft and feed pipe stiff shaft drive by conveyer axle box, and the rotation direction of this discharge nozzle stiff shaft and feed pipe stiff shaft is contrary.
The upper level that described storage tank discharge nozzle is positioned at one end of vertical storage tank inside is pruned one section of tube wall.
The shaped seals container that described vertical storage tank is top is hemispherical, bottom is back taper.
Connection between described storage tank feed pipe and conveyer discharge nozzle, the connection between storage tank discharge nozzle and conveyer feed pipe all adopt adpting flange to realize.
Described flexible shaft joint comprises the cubic spindle nose being fixed in flexible shaft end, the cubic axis hole being fixed in discharge nozzle stiff shaft end and lock screw, and described cubic spindle nose to insert in cubic axis hole and both fixed by lock screw.
The beneficial effects of the utility model are: increase by an auger conveyor outward at vertical storage tank and puddle power as Matter Transfer, conveyer entrance, export and connect respectively at outlet, entrance, form a material self-circulation system closed, material is iterative cycles within the system, realizes puddling.Vertical storage tank bottoms material enters auger conveyor through outlet, and enters in tank from reservoir inlet and reach tank deck and fall, and in the storage tank of accumulation, material is in folding process, mid portion moves down comparatively fast, surrounding is comparatively slow, replaces, shears, realize puddling between component.Through the circulation gone round and begun again, material is tending towards even.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
See Fig. 1 to Fig. 5, vertical storage tank granular material self-loopa mixing system of the present utility model draws together vertical storage tank 1 and auger conveyor, described vertical storage tank 1 is provided with storage tank feed pipe 2 and storage tank discharge nozzle 3, and described auger conveyor comprises conveyer axle box 6 and is horizontally disposed with and the conveyer discharge nozzle 4 be interconnected and conveyer feed pipe 5;
Described storage tank feed pipe 2 one end is vertically arranged at vertical storage tank 1 inner upper end, the other end stretches out outside vertical storage tank 1 and is connected with described conveyer discharge nozzle 4, described storage tank feed pipe 2 inside is provided with can rotation and be fixed with the flexible shaft 7 of helical blade in pipe, described conveyer discharge nozzle 4 inside is provided with can rotation and be fixed with the discharge nozzle stiff shaft 8 of helical blade in pipe, described flexible shaft 7 upper end is suspended from storage tank feed pipe 2, lower end by flexible shaft joint and described discharge nozzle stiff shaft 8 affixed, described flexible shaft 7 is arranged in storage tank feed pipe 2 by support 9, this flexible shaft 7 upper end upwards extends through support 9 and this flexible shaft 7 can rotate relative to support 9, the design of support 9 can prevent flexible shaft 7 to rub at storage tank feed pipe 2 turning (stretching out tank skin) tube wall, and adopt support 9 to support, support 9 is seated at tube wall.
Described storage tank discharge nozzle 3 one end is horizontally set on vertical storage tank 1 inner bottom, the other end stretches out outside vertical storage tank 1 and is connected with described conveyer feed pipe 5, described conveyer feed pipe 5 inside is provided with can rotation and be fixed with the feed pipe stiff shaft 10 of helical blade in pipe, it is inner that described feed pipe stiff shaft 10 one end extends to storage tank discharge nozzle 3, and storage tank discharge nozzle 3 is identical with conveyer feed pipe 5 internal diameter;
Described discharge nozzle stiff shaft 8 and feed pipe stiff shaft 10 drive by conveyer axle box 6, and the rotation direction of this discharge nozzle stiff shaft 8 and feed pipe stiff shaft 10 is contrary, guarantees that material enters from conveyer feed pipe 5 continuously, conveyer discharge nozzle 4 exports.
The upper level that described storage tank discharge nozzle 3 is positioned at one end of vertical storage tank 1 inside is pruned one section of tube wall, is convenient to accept falling material feed and exhaust tube in storage tank.
Described vertical storage tank 1 for top be hemispherical, bottom is the shaped seals container of back taper.
Connection between described storage tank feed pipe 2 and conveyer discharge nozzle 4, the connection between storage tank discharge nozzle 3 and conveyer feed pipe 5 all adopt adpting flange to realize.
Described flexible shaft joint comprises the cubic spindle nose 11 being fixed in flexible shaft 7 end, the cubic axis hole 12 being fixed in discharge nozzle stiff shaft 8 end and lock screw 13, and described cubic spindle nose 11 to insert in cubic axis hole 12 and both fixed by lock screw 13.
Helical blade diameter fixing on flexible shaft 7, feed pipe stiff shaft 10, discharge nozzle stiff shaft 8 is less than the internal diameter of storage tank feed pipe 2, conveyer feed pipe 5, conveyer discharge nozzle 4 respectively.
Before work, the charging and discharging mouth capping of vertical storage tank 1 is opened, stiff shaft in conveyer feed pipe 5 is sent into along storage tank discharge nozzle 3 and puts in place, connect flange; Be connected with discharge nozzle stiff shaft 8 with flexible shaft joint, and connect storage tank discharge nozzle 3 and conveyer feed pipe 5 with flange.When power drive two stiff shafts rotate, tank bottom material is sent into conveyer continually, drops out from the storage tank feed pipe 2 of tank top, forms the circulation that goes round and begins again.In the tank piled up, material is in folding process, and mid portion moves down comparatively fast, and surrounding is comparatively slow, replaces, shears between component, is tending towards gradually puddling evenly.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are all included within scope of the present utility model.
