Abstract
The utility model discloses a fan air inlet with anti-abrasion ribs, which comprises a horn-shaped air cylinder. A rectifying cylinder is arranged on the outer periphery of the air cylinder, and a baffle plate is arranged at the end of the rectifying cylinder. The fan air inlet is characterized in that the anti-abrasion ribs are welded along an arc line position from a horn mouth of the air cylinder. The fan air inlet with anti-abrasion ribs has the advantages that the strength of the fan air inlet is enhanced, the service life a fan is prolonged, and equipment maintenance ratio is reduced.
Description
Technical field
The utility model belongs to mechanical field, relates to a kind of blower fan, is specifically related to a kind of air inlet that has the abrasionproof muscle.
Background technique
In the bigger occasion of some dust loading; the import wearing and tearing of induced draught fan such as coal powder fan are inevitable; after the intake grill wearing and tearing, not only fan efficiency reduces, and is threatening the safe operation of equipment; when serious by forced-stopping machine; the method that many blower fan producers take is the regular repairing of mending by replacing a damaged part, but the repairing difficulty is bigger, and some will remove the adjustment doors or the import airduct of intake grill front; it is bigger to repair difficulty, and effect neither be too desirable.
The model utility content
The model utility purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of antiwear air inlet that has the abrasionproof muscle to be provided.
Technological scheme: the air inlet that has the abrasionproof muscle described in the utility model, its objective is such realization: a kind of air inlet that has the abrasionproof muscle, the air duct that comprises horn shape, the periphery of air duct is provided with the rectification tube, rectification tube end is provided with baffle plate, begins to be welded with the abrasionproof muscle along the camber line position from the horn mouth of air duct.
As optimization: be spaced apart 50-60mm between the adjacent abrasionproof muscle.
As optimization: the material of abrasionproof muscle is the reinforcing bar of φ 16.
The installation of described abrasionproof muscle is not a snare one circle, but spiral addition, rotation direction is equal to the impeller rotation direction.
Described intake grill adopts Q345C, and it has better wear resistance than general Q235A.
Beneficial effect: the air inlet that has the abrasionproof muscle described in the utility model, increased the intensity of air inlet, prolonged the working life of blower fan, the device maintenance rate reduces.
Description of drawings
Fig. 1 is the structural representation that has the air inlet of abrasionproof muscle described in the utility model;
Fig. 2 is the described stereogram that has the air inlet of abrasionproof muscle of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment:
Embodiment
