Description
Technical field
The utility model relates to a kind of coal-grinding cylinder of abrasion-proof steel ball coal pulverizer.
Background technology
At present, low speed coal mill obtains and applies more widely in China's thermal power generation unit, and low speed coal mill coal adaptability is wide, safe and reliable to operation, easy to maintenance.But its metal consumption is large, and powder process power consumption is high, according to statistics, the wearing and tearing that low speed coal mill generally often grinds 1t coal steel ball are 300 ~ 350 g, indivedual coal pulverizer is even higher, adds the wearing and tearing of lining plate of coal grinder, and it is usual about up to 0.5 ‰ that total metal damages the ratio grinding coal with institute.In conjunction with performance parameter and the coal characteristic of China's low speed coal mill, prepare that a kind of coal-grinding is effective, the coal pulverizer of the ball consumption that simultaneously can reduce ball mill and power consumption seems most important.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of novel be applied on abrasion-proof steel ball coal pulverizer coal-grinding drum part.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of coal-grinding cylinder of abrasion-proof steel ball coal pulverizer, comprise cylindrical shell and cylinder chamber, cylindrical shell two ends are respectively coal feed point and coal outlet, cylinder inboard wall connect the steel ball that several diameters are different, described steel ball is connected with inwall by crushing rod, and the connected steel ball size of length of crushing rod is proportional.
The coal-grinding cylinder that the utility model provides is the improvement carried out on the cylinder basis of routine, and the parts such as the structure of cylindrical shell and the lining plate of coal grinder that comprises thereof are identical with prior art.
Preferably, the steel ball size that the utility model needs is 20-80mm, and the diameter of steel ball comprises 20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm.
Preferably, the length of crushing rod is 0.8-1.2 times of the steel ball size that it connects.The structural benefit of such design is, large ball, above, for the coal of broken bulk, becomes fritter, continues to collide with bead below after the coal fragmentation of bulk, the crushing rod is simultaneously connected with steel ball and play the effect of broken coal cinder.The material of crushing rod can be identical with steel ball.
Preferably, the steel ball of different-diameter arranges in regular mode on cylinder inboard wall.The arrangement mode of steel ball is the important technical that the utility model reaches that the best carries out effect, and the utility model provides following 2 arrangement modes.
One, with the vertical section of cylindrical shell for benchmark, the steel ball arrangement regulation of different-diameter is large to partial circulating arrangement for having.
Two, with the vertical section of cylindrical shell for benchmark, the steel ball arrangement regulation of different-diameter littlely to arrange to arrive greatly partial circulating again for having.
Further, crushing rod is fixed on cylinder inboard wall with certain angle of inclination.Crushing rod inclined design can strengthen the collision effect of coal cinder and steel ball.The angle of inclination of crushing rod and cylinder inboard wall is 20-45 degree.Preferably, the angle of inclination of crushing rod and cylinder inboard wall is 30 degree.
The beneficial effects of the utility model:
The coal-grinding roller frame that the utility model provides is simple, designs ingenious, and broken coal is effective, and the coal pulverizer of ball consumption and power consumption ratio routine is little.
