Described feed impeller comprises connecting axle, blade, and described connecting axle runs through described feed bearing and is connected with described feed shaft coupling, and described blade is fixed with one end of described connecting axle, and the quantity of described blade is a plurality of.
The inner side of described cabinet is provided with crashproof armor, and described crashproof armor is secured by bolts in described cabinet.
The top of described cabinet is provided with coal outlet, and described coal outlet is communicated with described cabinet, and described coal outlet be positioned at described strike impeller directly over.
On described strike shaft coupling, feed shaft coupling, be all connected with motor, the rotating speed of the motor connecting on wherein said strike shaft coupling is 750-1500r/min.
Described beater plate is 16Mn pressboard.
Described blade is " U " shape structure, and is enclosed with wear-resistance protective sleeve on described blade.
The blower mill obtaining by above-mentioned design of the present utility model, its beneficial effect is:
By feed impeller, the coal cinder of below is lifted up, prevent that coal cinder from depositing in cabinet bottom, raises the efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of blower mill described in the utility model;
Fig. 2 is the structural representation of feed impeller described in the utility model;
In figure, 1, cabinet; 11, coal-in port; 12, coal outlet; 13, crashproof armor; 2, motor; 3, hit bearing; 31, hit shaft coupling; 32, hit impeller; 33, beater plate; 4, feed impeller; 41, feed bearing; 42, feed shaft coupling; 43, connecting axle; 44, blade; 45, wear-resistance protective sleeve.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
Fig. 1 is the structural representation of blower mill described in the utility model, Fig. 2 is the structural representation of feed impeller described in the utility model, as Fig. 1, shown in Fig. 2, a kind of blower mill, comprise cabinet 1, the left side of described cabinet 1 is provided with coal-in port 11, described coal-in port 11 is communicated with described cabinet 1, the right side of described cabinet 1 is connected with strike shaft coupling 31 by hitting bearing 3, described strike bearing 3 runs through the right side of described cabinet 1 and is connected with the strike impeller 32 in described cabinet 1, on described strike impeller 32, beater plate 33 is installed, the below of described strike impeller 32 is provided with feed impeller 4, described feed impeller 4 is connected with feed shaft coupling 42 by feed bearing 41.
Described feed impeller 4 comprises connecting axle 43, blade 44, and described connecting axle 43 runs through described feed bearing 41 and is connected with described feed shaft coupling 42, and described blade 44 is fixed with one end of described connecting axle 43, and the quantity of described blade 44 is a plurality of.
The inner side of described cabinet 1 is provided with crashproof armor 13, and described crashproof armor 11 is secured by bolts in described cabinet 1.
The top of described cabinet 1 is provided with coal outlet 12, and described coal outlet 12 is communicated with described cabinet 1, and described coal outlet 12 be positioned at described strike impeller 32 directly over.
