Description
Technical field
The present invention relates to cement manufacture plant, specifically is a kind of cement grinding mill forging grader.
Background technology
The forging classification is exactly that sorting and classification are carried out in the forging that mixes different size.
The employed forging of cement grinding mill divides two big classes, promptly common forging and miniature forging.Common forging commonly used has three kinds of specification: Φ 20 * 25, Φ 25 * 30, Φ 30 * 35.Miniature forging commonly used has five kinds of specification: Φ 10 * 12, Φ 12 * 14, Φ 14 * 16, Φ 16 * 18, Φ 18 * 20.
The miniature forging of using with storehouse behind the grinding machine is example, and grinding machine begins to produce before the cement, and the miniature forging of different size is prepared within the grinding machine of packing into different heavyweights respectively.But, in cement production process, constantly grinding mutually, impacting between the miniature forging; Also exist between miniature forging and the grinding mill barrel liner plate and impact and grinding, also grinding between miniature forging and the material, therefore miniature forging is consumed gradually, and size is constantly dwindled, and miniature forging useful load constantly descends in the mill.According to the material difference of miniature forging, its consumption is about 50 grams/ton cement, and in order to guarantee the stable of mill output, (about 1-2 month) miniature forging of interpolation in mill regularly will in time be brought down stocks after use a period of time (1～2 year) and grating again.
At present cement production enterprise is not also having good equipment and way aspect cement grinding mill forging storehouse cleaning scum and the forging classification again, most of enterprise all is the way that adopts artificial separation basically, because the useful load of miniature forging is bigger in the mill, two storehouse cement grinding mills with the roll squeezer system are example, and the storehouse total useful load of miniature forging is 85 tons behind Φ 3.0 * 13.0m cement grinding mill; The total useful load of Φ 3.2 * 13.0m cement miniature forging in abrading-ball storehouse is 105 tons, and the total useful load of Φ 4.2 * 14.5m cement miniature forging in abrading-ball storehouse is 200 tons.Adopt that manual hierarchical approaches labour intensity is big, environment is abominable, and grading effect is undesirable.
Summary of the invention
The object of the present invention is to provide a kind of cement grinding mill forging grader, this classification function is separated the scum in the forging, the forging that mixes different size can also be carried out simultaneously sorting and sort out, classification efficiency height not only, and can alleviate working strength of workers greatly.
The technical scheme that realizes the object of the invention is:
Cement grinding mill forging grader of the present invention, by frame, dynamical system, the forging storehouse, the classification roto-siofter, the scum collection bucket, the forging collection bucket of different size, the foreign material collection bucket is formed, frame is a structural member, dynamical system is arranged on the frame of an end of classification roto-siofter, classification roto-siofter main shaft two ends are by bearing block support, classification roto-siofter main shaft connects with dynamical system, the forging storehouse is communicated with the classification roto-siofter, the scum collection bucket, the forging collection bucket separately separately independently, corresponding with the classification section, leave on the frame that is set in sequence in classification roto-siofter periphery that can allow forging roll out the gap scum collection bucket with the classification roto-siofter, the forging collection bucket is provided with the outlet of scum and forging.
Described dynamical system is mainly the forging grader power is provided, and motor is connected with drive pulley, and driven pulley drives decelerator, and is connected by the main shaft of sliding cross coupling with the classification roto-siofter.
Described classification roto-siofter is by importing helical blade, the revolution screen drum, the screen drum bearing support, internal helical blades and main shaft are formed, the revolution screen drum by the main shaft frame on the bearing block on the frame, import helical blade and be positioned at the classification roto-siofter foremost, internal helical blades is arranged in the classification section of classification roto-siofter, the screen drum bearing support is arranged between each classification section of screen drum, and be communicated with each classification section, screen drum is separated into scum screening district, the first screening district, the second screening district, the 3rd screening district, the 4th screening district, the 5th screening district, the screen drum head end is little, tail end is big, gradient is 3～5 °, on classification roto-siofter screen drum, be provided with oval shape sieve aperture with the main shaft vertical fragmentation, the miniature forging of classification, the specification of the oval shape sieve aperture on the screen drum is followed successively by wide 10mm, 12mm, 14mm, 16mm, five kinds of specifications of 18mm; The common forging of classification, the sieve aperture specification on the screen drum is wide to be 20mm, 25mm, three kinds of specifications of 30mm.
During work, mixing forging in the forging storehouse enters classification roto-siofter front portion by by-pass valve control, the importing helical blade of classification roto-siofter will mix forging and send into the screening district, first road of classification roto-siofter (the wide 10mm of being of oval shape sieve aperture), because the gyroscopic action of classification roto-siofter, the following scum of 10mm at first is sized out and sends into the scum collection bucket, because the classification rotary main shaft has designed certain gradient, each classification section is communicated with by the screen drum bearing support, remaining mixing forging enters screening district, second road (the wide 12mm of being of oval shape sieve aperture) automatically, the forging of Φ 10～12 is sized out and sends into corresponding forging collection bucket in screening district, second road, as a same reason, Φ 12～14, Φ 14～16, Φ 16～18, the miniature forging of various different sizes such as Φ 18～20 is sieved and classification automatically.The sorting of common forging is with miniature forging.
Advantage of the present invention is: classification is accurate, scum and forging can be separated, and the forging that mixes different size can also be carried out sorting simultaneously and sort out the classification efficiency height; Can alleviate working strength of workers greatly.
