Abstract
The invention discloses a shaft head protecting device, and relates to an impeller shaft of a powder feeder in a power plant, in particular to protection for a shaft head of the impeller shaft of the powder feeder. The shaft head protecting device comprises the powder feeder, the impeller shaft and a worm, wherein the powder feeder is connected with the impeller shaft by a shaft sleeve; the worm is connected with the impeller shaft by a coupler; and the part of the impeller shaft, which is close to the shaft sleeve, is provided with a fixed ring. The shaft head protecting device has the beneficial effects that the fixed ring wraps the shaft head of the impeller shaft, so that the strength of the shaft head is increased and the damage of the shaft head is avoided.
Description
Technical field
The present invention relates to the paddle shaft of power plant's machine supplying powder, refer more particularly to the protection of machine supplying powder paddle shaft spindle nose.
Background technology
The large power plant boiler is through the machine supplying powder pulverized coal conveying, and the machine supplying powder machine supplying powder is through worm screw impeller axle, and paddle shaft drives impeller rotation in the machine supplying powder, through blowing engine coal dust is transported in the boiler again.Because coal dust constantly increases in the machine supplying powder, the impeller resistance increases, and often causes the paddle shaft spindle nose to damage, and ordinary production is caused damage.
Summary of the invention
The present invention is just in order to address the above problem, and a kind of fender guard of spindle nose is provided.
In order to achieve the above object, the technical scheme of the present invention's employing is:
A kind of spindle nose fender guard; Comprise machine supplying powder, paddle shaft, worm screw; Said machine supplying powder is connected with paddle shaft through axle sleeve, and said worm screw is connected with paddle shaft through coupler, it is characterized in that: said paddle shaft is provided with set collar near the spindle nose at axle sleeve position.
The invention has the beneficial effects as follows that set collar wraps the spindle nose of paddle shaft, increased the intensity of spindle nose, avoided the damage of spindle nose.
Description of drawings
Fig. 1 is a scheme drawing of the present invention.
Among the figure: 1. machine supplying powder; 2. paddle shaft; 3. axle sleeve; 4. set collar; 5. coupler; 6. worm screw.
The specific embodiment
Can know by accompanying drawing; The present invention includes machine supplying powder 1, paddle shaft 2, worm screw 6; Said machine supplying powder 1 is connected with paddle shaft 2 through axle sleeve 3; Said worm screw 6 is connected with paddle shaft 1 through coupler 5, in order to increase the intensity of paddle shaft 2, on the spindle nose of said paddle shaft 2 near axle sleeve 3 positions, is provided with set collar 4.Set collar 4 tightly wraps up spindle nose, and spindle nose is played a protective role, and has avoided the damage of spindle nose.
Claims (1)
1. spindle nose fender guard; Comprise machine supplying powder, paddle shaft, worm screw; Said machine supplying powder is connected with paddle shaft through axle sleeve, and said worm screw is connected with paddle shaft through coupler, it is characterized in that: said paddle shaft is provided with set collar near the spindle nose at axle sleeve position.
