Specific embodiment

It, below will be to use required in embodiment in order to illustrate more clearly of the technical solution of the utility model embodiment Attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is some embodiments of the utility model, for this For the those of ordinary skill of field, without creative efforts, it can also be obtained according to these attached drawings others Attached drawing.

Referring to Fig. 1 to Fig. 4, the utility model embodiment provides a kind of drying of ladder variable formula helical feed Fluorspar Powder and sets It is standby, including drying oven 10, loader 20, discharger 30, hot air pipe 40, drying oven 10 are hollow closing cylinder, are also being dried Several material rotating plates 11 are set on the inner wall of furnace 10, and material rotating plate 11 is the arc panel being obliquely installed to 30 direction of discharger, loader 20 and discharger 30 be respectively set and tilted down with the feeding end of drying oven 10 and discharge end, drying oven 10 to 30 direction of discharger Setting, drying oven 10 have external drive to drive axial rotation, and the left end of loader 20 stretches to inside drying oven 10, by fluorite Powder is fed through inside drying oven 10, and discharger 30 is slope sleeve, and the right end of discharger 30 is sheathed on the discharge end of drying oven 10, For accepting the material of output, the left end of discharger 30 tilts down to form slope, so that material skids off, the air inlet of hot air pipe 40 End stretches in drying oven 10 from the discharge end of drying oven 10, also opens up sirocco reclamation mouth, feeding at the feeding end of drying oven 10 Device 20 includes shell 21, spiral handspike 22, elevating hopper 23, and shell 21 is hollow cylinder, is also arranged on 21 one end top of shell Feeding port, elevating hopper 23 are connect with feeding port, and spiral handspike 22 is set to inside shell 21, are arranged on 22 outer wall of spiral handspike Helical blade 24, transition steps 25 are arranged on the spiral handspike 22 also below feeding port, and transition steps 25 are with hollow closing Cylindrical body, transition steps 25 are sheathed on outside spiral handspike 22, and part helix blade 24 is wrapped in by the side wall of transition steps 25 Inside, the leakage of part helix blade 24 is in the outside of transition steps 25, to be located at below feeding port by the control of transition steps 25 Helical blade 24 gulp down doses.

In the program, transition steps 25 are set at the feeding port below lower hopper, are pushed away with not destroying former spiral under realization It under the premise of bar 22 and helical blade 24, inlet amount to feeding port or gulps down doses and limits, when material stream in elevating hopper 23 After entering feeding port, the maximum gauge of material accumulation is the thickness H of the helical blade 24 of the top of transition steps 25, in elevating hopper 23 The maximum that enters in loader 20 of powder be H, and these powders continue in successive transmission process, fall into shell 21 Portion, thickness with can not be greater than the 1/2 of 21 diameter of shell, so thoroughly solving the problems, such as overload.

Further, the diameter of the transition steps 25 is adjustable.

Further, pass-through cuts 251, the trimming of 251 two sides of pass-through cuts are axially opened up in transition steps 25 Respectively first side 252 and second side 253, first side 252 are docked or are superimposed with second side 253, to pass through superposition Mode adjust the diameters of transition steps 25, and then adjust loader 20 gulps down doses.

When first side 252 and second side 253 are superimposed, the overlap width of the two is wider, so that 25 shape of transition steps At hollow cylinder diameter it is narrower, then the area of helical blade 24 of the leakage outside transition steps 25 is bigger, then gulps down material Amount is bigger, conversely, gulping down, doses is smaller, so realizes and gulps down the adjustable of doses according to required by technique.Certainly the two superposition After transition steps can be fixed using fixing piece, avoid unclamping.

Module or unit in the utility model embodiment device can be merged according to actual needs, divide and be deleted Subtract.

Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly Interest field, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and according to this reality The equivalent variations made by novel claim, still falls within the scope of the utility model.
