Circulation feed back deironing apparatus
Technical field
The utility model relates to cement auxiliary material process units field, particularly a kind of circulation feed back deironing apparatus.
Background technology
Contain a large amount of iron in the slag of production cement.In follow-up process of lapping, these iron compounds in material can make the cement ball mill wearing and tearing more serious.
Summary of the invention
The purpose of this utility model is to provide a kind of circulation feed back deironing apparatus of strengthening de-ferrous effect.
To achieve these goals, the circulation feed back deironing apparatus that the utility model provides comprises: the storage bin that is connected successively, the first material-conveying belt, deironing apparatus, the second material-conveying belt, feed back storehouse, lifting device and feed back material-conveying belt, the feed back material-conveying belt is connected to storage bin.Thus, after the material in discharging bin enters the deironing apparatus deironing by the first material-conveying belt, enter the feed back storehouse by the second material-conveying belt, by lifting device with the material lifting in the feed back storehouse to the feed back material-conveying belt, transmit back storage bin.So circulation is carried out deironing to the material in storage bin, reduces the iron content in material.
In some embodiments, deironing apparatus is the magnetic separation roller, and the conveying roller of the first material-conveying belt and the second material-conveying belt link is the magnetic separation roller, and the second material-conveying belt is positioned at the front lower place of the first material-conveying belt transmission direction.Thus, use the magnetic separation roller as deironing apparatus, simple in structure, reduced energy consumption and production cost.
Circulation feed back deironing apparatus of the present utility model utilizes the magnetic separation roller to carry out circulation deferrization to the material in feed bin, has reduced the iron-holder in the material, has reduced simultaneously energy consumption.
Description of drawings
Fig. 1 is the structural representation of the circulation feed back deironing apparatus of a kind of embodiment of the utility model.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail explanation.
Fig. 1 has schematically shown the circulation feed back deironing apparatus according to a kind of embodiment of the utility model.
As shown in Figure 1, circulation feed back deironing apparatus of the present utility model comprises: storage bin 10, the first material-conveying belt 20, deironing apparatus 33, the second material-conveying belt 30, feed back storehouse 40, lifting device 50 and feed back material-conveying belt 60.
As shown in Figure 1, the first material-conveying belt 20 wherein an end be located at storage bin 10 feed opening 101 belows; The second material-conveying belt 30 is connected with the first material-conveying belt 20, and is positioned at the below of the first material-conveying belt 20; The end that the second material-conveying belt 30 is not connected with the first material-conveying belt 20 passes into feed back storehouse 40; Be provided with lifting device 50 in feed back storehouse 40, the output of lifting device 50 is connected with feed back material-conveying belt 60; The end that feed back material-conveying belt 60 is not connected with feed back storehouse 40 is by storage bin 10.
Deironing apparatus 33 is the magnetic separation roller.The conveying roller of the first material-conveying belt 20 and the second material-conveying belt 30 links is the magnetic separation roller, and the first material-conveying belt 20 is along arrow A direction transmission in figure.An end below that is provided with the magnetic separation roller in the first material-conveying belt 20 is provided with iron charge passage 2, iron charge passage 2 be positioned at the magnetic separation roller under, the second material-conveying belt 30 is positioned at the first material-conveying belt 20 ends (magnetic separation roller end) front lower place.
Material is by the first material-conveying belt 20 transmission, to the first material-conveying belt 20 ends (magnetic separation roller end), material falls into front lower place the second material-conveying belt 30 along the arrow B direction and continues transmission under the effect of gravity and inertia, iron tramp is being adsorbed under the magneticaction of magnetic separation roller on the first material-conveying belt 20, iron tramp is when magnetic separation roller half thoughtful magnetic separation roller lower surface, fall under its action of gravitation, fall into iron charge passage 2 along the arrow C direction, realized thus the separation of iron tramp, the material of separating ferrum impurity continues along the second material-conveying belt 30 transmission.
Circulation feed back deironing apparatus of the present utility model, after material in discharging bin enters the deironing apparatus deironing by the first material-conveying belt, enter the feed back storehouse by the second material-conveying belt, by lifting device with the material lifting in the feed back storehouse to the feed back material-conveying belt, transmit back storage bin.So circulation is carried out deironing to the material in storage bin, reduces the iron content in material, and it utilizes the magnetic separation roller to carry out circulation deferrization to the material in feed bin, has reduced the iron-holder in the material, has reduced simultaneously energy consumption.
