The utility model has following advantageous effects:
(1) by setting the first feed screw and the second feed screw, raw material is sent to the by the first feed screw
In two feed screws, raw material is transferred in rotary kiln kiln by the second feed screw, and the second feed screw is can front and back
Mobile form can be sent raw material to rotary kiln by controlling the length that the second feed screw is extend into rotary kiln kiln
Different location, avoid its accumulation at kiln tail；
(2) on the one hand the setting of collecting hood can play the role of protection, on the other hand can be to generating in calcination process
Dust vapor etc. is collected separation, and a part of dust deposit gets off, the exhaust that another part dust and steam etc. pass through top
Mouth discharge.
(3) anti-bl bridge layer structure is simple, and only provides rotational power using the first feed screw, without being additionally provided
Power saves the energy and can be good at preventing arch formation, reduces the failure rate of equipment and the labor intensity of worker.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
1 lower hopper, 2 first feed screws, 3 second feed screws, 4 collecting hoods, 5 rotary kilns, 6 are moved in figure
Dynamic trolley, 7 motors, 8 belts, 9 tracks, 10 anti-bl bridge layers, 11 paddles.
Specific embodiment
It is right with reference to the accompanying drawings and detailed description in order to which the structure and principle of the utility model is more clearly understood
The utility model is described in detail:
As shown in Figure 1, a kind of rotary kiln feeding device, including lower hopper 1, the first feed screw 2, the second screw feeding
Machine 3 and collecting hood 4, the first feed screw 2 are obliquely installed, and feed inlet is located at lower end and is connected to lower hopper 1, discharge port position
It is connected in upper end with the feed inlet of the second feed screw 3, the second feed screw 3 is horizontally disposed and can be moved forward and backward；This dress
Setting further includes collecting hood 4, and the kiln tail of rotary kiln 5 is arranged in collecting hood 4, and the feed inlet of rotary kiln kiln is extend into collecting hood 4
And can axially be rotated in collecting hood 4 along it, collecting hood 4 is provided with door to be opened/closed, the second spiral on corresponding another side
