A kind of pulverizer of regulating
Technical field
The present invention relates to the size reduction machinery technical field, specifically is a kind of pulverizer of regulating.
Background technology
Mainly contain hammer sieve formula and the broken two kinds of structures of formula of dragon at the pulverizer that uses on the market at present.Hammer sieve formula pulverizer mainly is made up of parts such as motor, rotor, hammer leaf, sieves, and hammer leaf links to each other with rotor.Its operation principle is: rotated at a high speed by driven by motor rotor and hammer leaf, material is constantly pulverized after the hammer leaf that is subjected to rotation at a high speed clashes into, and qualified material powder is discharged underproof then the continuation and pulverized from sieve aperture.Distance between hammer leaf and the sieve has determined that can qualified material by timely and a large amount of discharge, but, wearing and tearing and distortion all can take place in hammer leaf and sieve in use for some time, distance between the hammer sieve changes thereupon, thereby influences the timely discharge of qualified material, and the material ring is thickening constantly, like this, the complete machine operating efficiency not only reduces, and the internal body temperature also can constantly raise, and very easily causes the damage of equipment.In order to make the distance that can remain a best between the hammer sieve, the operating efficiency and the service life of guaranteeing complete machine, people have used several different methods, but all fail to reach desirable effect.
China Patent No. " 200620035958.5 " discloses a kind of adjustable hammer mill, comprise charging aperture, casing, the several piece side plate, assembly is impacted in the revolution that has several tups, have relief hole on, cavity of resorption crushing and screening plate, adjusting device and discharging opening, its improvements are: described adjusting device links to each other with screen frame (unit) under being arranged on cavity of resorption crushing and screening plate and passes outside the casing, when tup and cavity of resorption crushing and screening plate generation wearing and tearing, adjust the height of cavity of resorption crushing and screening plate by adjusting device, the gap between tup and the cavity of resorption crushing and screening plate is transferred to the best.Though this utility model has realized the adjustability of distance between the hammer sieve, but, also have certain weak point: material will be along with hammer leaf rotates together in the same way after entering internal body, qualified material all might discharged by sieve with any tangential direction of sieve, no matter be upper and lower, left and right, therefore, depend merely on dealing with problems that the distance of regulating between cavity of resorption crushing and screening plate and the tup can not be real.
Summary of the invention
It is a kind of simple in structure that technical problem solved by the invention is to provide, and is convenient to operation, and can be comprehensive the pulverizer regulated of distance between the governor weight sieve.
