Abstract
The utility model provides an annular knife blade installed at a material inlet part of a fan, which is characterized in that the annular knife blade installed at the material inlet part of the fan is provided with an annular knife blade, wherein two or more than two zigzag knife edges are formed on an inner circle of the annular knife blade, the annular knife blade is arranged on the material inlet of the fan, and a connecting part of the annular knife blade and the material inlet of the fan is provided with two or more than two screw bolts. The utility model belongs to the annular knife blade installed at the material inlet part of the fan and is matched with a rotary knife blade arranged on a wheel disc to be used, when the wheel disc rotates, the centrifugal force is generated on materials, the rotary knife blade arranged on the wheel disc is matched with the annular knife blade to be used, solid materials are effectively cut and mashed, mashed material particles are small, and the pulverization effect is good.
Description
Technical field
The utility model relates to a kind of annulus blade, particularly a kind of annulus blade that is installed in blower fan charging aperture place.
Background technology
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and it is a kind of driven fluid machinery.Blower fan is the custom abbreviation of China to gas compression and gas conveying machinery, and usually said blower fan comprises ventilation blower, air blast, and compressor and Roots blower, but do not comprise piston compressor isometric(al) formula air blast and compressor.Gas compression and gas conveying machinery are that a mechanical switch of rotation is gas pressure energy and kinetic energy, and gas is transferred out.Blower fan can quicken air and flow, and can discharge gas fast, is applicable to multiple occasion, as ventilation, dust discharge and the cooling of factory, mine, tunnel, cooling tower, vehicle, boats and ships and building.
After installing blade in the blower fan, can be used for handling the solid material of smashing, but in processing procedure, the limited length of wheel disc cutter, material is stirred in the process of smashing by the wheel disc blade rotation, tends to because of being subjected to action of centrifugal force, outwards disperse, therefore blade can not all act on power on the material, and the material particles after the processing is big, precision is lower, and effect is relatively poor.
The utility model content
Problems such as the utility model provides a kind of annulus blade that is installed in blower fan charging aperture place, and the material particles after can effectively solving solid material that prior art exists and handling is big, precision is lower, effect is relatively poor.The utility model relates to a kind of annulus blade that is installed in blower fan charging aperture place, it is characterized in that: an annulus blade is arranged, offer serrated edge on the circle in the annulus blade, the annulus blade is installed on the blower fan charging aperture.It is characterized in that: the number of described serrated edge is two or more.It is characterized in that: the junction of described annulus blade and blower fan charging aperture is provided with two or more bolts.The utility model is the annulus blade of installing at blower fan charging aperture place, be used with the rotating blade that is provided with on the wheel disc, during the wheel disc spins material is produced centrifugal force, rotating blade on the wheel disc and the annulus blade in the utility model are used, effectively with solid material cutting and blend less, the good crushing effect of the material particles that blends.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is the structural representation of the utility model duty.
Below in conjunction with accompanying drawing the utility model is described.
The specific embodiment
Comprise blower fan charging aperture 1 among the figure, described blower fan charging aperture 1 is provided with annulus blade 2, and circle is provided with serrated edge 3 in the described annulus blade 2.The number of described serrated edge 3 is two or more.Be covered with serrated edge 3 on the circle in the annulus blade 2, each serrated edge is closely arranged, to guarantee the solid material crushing effect.The junction of described annulus blade and blower fan charging aperture is provided with two or more bolts 6.The junction of described annulus blade and wheel disc is provided with two or more bolts, and preferred six bolts are guaranteed the fixed effect of annulus blade.
The utility model at work, be used with the blower fan wheel disc 5 that has long blade 4, after the solid material of tentatively smashing enters blower fan from blower fan charging aperture 1, long blade fast rotational on the wheel disc is with material cutting and rubbing, the centrifugal forces affect that wheel disc that material can be rotated produces and gathering on the annulus blade, long blade cooperates with annulus blade of the present utility model, realizes that better material rubs effect.
Claims (3)
1. annulus blade that is installed in blower fan charging aperture place is characterized in that: an annulus blade is arranged, offer serrated edge on the circle in the annulus blade, the annulus blade is installed on the blower fan charging aperture.
2. a kind of annulus blade that is installed in blower fan charging aperture place as claimed in claim 1 is characterized in that: the number of described serrated edge is two or more.
3. a kind of annulus blade that is installed in blower fan charging aperture place as claimed in claim 1, it is characterized in that: the junction of described annulus blade and blower fan charging aperture is provided with two or more bolts.
