Abstract
The utility model relates to a hammer impact crusher, which is a high-efficiency energy-saving fine crusher especially suitable for crushing various medium-hardness materials. The technical scheme is mainly characterized in that a gap H between a vector radius R of the arc-shaped sieve plate 4 and a turning radius R of the hammer head 2 is gradually reduced from the downward turning side to the upward turning side of the hammer head, and for convenience in processing, the arc-shaped part of the arc-shaped sieve plate 4 can be designed into a section of arc which is eccentric H with the turning center of the hammer head 2. The fine crusher has the advantages of high efficiency and remarkable energy saving for feeding limestone with the granularity of less than 100 mm and discharging the limestone with the granularity of less than 5 mm.
Description
The utility model relates to a kind of tup impact breaker, is a kind of energy-efficient fine crusher that is specially adapted to broken various medium hardness materials.
The arc screening plate of existing tup impact breaker is designed to circular arc mostly, and its center of circle is all concentric with the tup centre of gyration, although this disintegrating machine has fully been realized the strike effect of tup counterpunch board to material, but fail to utilize tup and sieve plate squeezing action, be unfavorable for that also fines in time discharges material.CN2180326y disclosed a kind of " hammer ring disintegrating machine " is exactly an example, and this disintegrating machine is added with the range adjuster of regulating the distance between rotor and the tup in the sieve plate termination, but its regulative mode does not change the concentric circles state of sieve plate and tup.
The purpose of this utility model is that existing strike effect has the energy-efficient fine crusher of squeezing action again to a kind of tup of design to material.
The utility model is achieved in that
A kind of energy-efficient fine crusher, the casing that relates to band charging aperture and discharging opening, be fixed in the counterpunch board of the casing inner wall first half, be fixed on the casing and be positioned at the arc screening plate of casing Lower Half, in the cavity of counterpunch board and arc screening plate formation, the rotor of band tup is housed, and the rotating shaft of rotor is passed casing and is driven by transmission mechanism, be characterized between arc screening plate vector radius r and the tup radius of gyration R gap H from tup backspin side on revolve side progressively from large to small.
Further scheme is, arc screening plate vector radius r=R+h+K θ (millimeter), and R is the tup radius of gyration in the formula, h is the minimum clearance of tup outer rim and arc screening plate, θ is arc screening plate vector radius r and horizontal angle (radian), and K is a coefficient, K=5～15.
Another kind of embodiment of the present utility model is, the arch section of arc screening plate is one section circular arc with the eccentric h of tup centre of gyration along continuous straight runs.
The utility model has the advantages that: since the gap H between arc screening plate vector radius r and the tup radius of gyration R from tup backspin side on revolve side progressively from large to small, therefore be in that larger particles material on the arc screening plate will be subjected to increasing extruding force along with the rotation of tup and by broken thin, help tup simultaneously and the fines on the arc screening plate is scraped in the sieve aperture of arc screening plate and discharged, this design also helps puts the larger particles material that stays on arc screening plate and is in time sent in the back cavity broken once more by tup.
Fig. 1 is a cutaway view of the present utility model.
Fig. 2 is the design principle figure of a kind of embodiment of the present utility model.
Fig. 3 is the design principle figure of another kind of embodiment of the present utility model.
Below in conjunction with accompanying drawing the utility model is done detailed description.
As Fig. 1 and Fig. 2, a kind of energy-efficient fine crusher, the casing 5 that relates to band charging aperture 7 and discharging opening 6, be fixed in the counterpunch board 3 of the casing 5 inwall first halves, be fixed on the casing 5 and be positioned at the arc screening plate 4 of casing 5 Lower Halves, in the cavity that counterpunch board 3 and arc screening plate 4 constitute, the rotor 1 of band tup 2 is housed, tup 2 is fixed on the rotor 1, the rotating shaft of rotor 1 is passed casing 5 back and is driven by transmission mechanism, wherein, the gap H between the vector radius r of arc screening plate 4 and tup 2 radius of gyration R from tup 2 backspin sides on revolve side progressively from large to small, and r=R+h+K θ (millimeter), h is the minimum clearance of tup 2 outer rims and arc screening plate 4 in the formula, and the big I of h requires to design according to the difference of particle size after cracking, and θ is arc screening plate 4 vector radius r and horizontal angle (radian), K is a coefficient, K=5～15.
Its course of work is, after raw material enters from charging aperture 7, at a high speed the tup 2 of rotation make raw material between tup 2 and counterpunch board through repeatedly colliding and strike is broken, fall into then on the arc screening plate 4, fine granular materials is promptly by discharging in the eyelet of discharging or scraped by tup 2 arc screening plate 4 in the eyelet of arc screening plate 4, part larger particles material is extruded back in small, broken bits and discharges between tup 2 and arc screening plate 4, part larger particles material is sent in the back cavity broken once more by tup 2.
Fig. 3 is the design principle figure of another kind of embodiment of the present utility model, the arch section that is characterized in arc screening plate 4 is one section circular arc with the eccentric h of tup 2 centre of gyration along continuous straight runs, compare circular arc sieve plate 4 easier processing and fabricatings shown in Figure 3 with arc screening plate 4 shown in Figure 2.
This fine crusher is specially adapted to broken medium-hard material, and for the lime stone of material size less than 100 millimeters, discharging-material size can reach below 5 millimeters, and its energy-saving effect is very remarkable, and efficient is higher than existing similar disintegrating machine.
