Abstract

The utility model relates to a vertical compound counterattack hammer type crusher used for crushing materials, which comprises a cylindrical body, wherein, lining boards and partition boards are arranged on the inner wall. An upper cover and a lower cover are respectively fixed on the upper and the lower ends of the cylindrical body, and a hopper and a feeding hopper are respectively arranged on the upper cover and the lower cover. Both ends of the main shaft are positioned at the middle parts of the upper and lower covers, two rows of hammer heads and fixed rotors are positioned in turn on the main shaft, and striking plate hammers are installed on the fixed rotors. The hammer heads are used for carrying out two stage crushing on the materials, and the striking plate hammers on the fixed rotors are used for secondary crushing on the materials so as to make the materials epigranular. Additionally, the secondary hammer crushing meets the low requirements to the materials crushed so that the crusher can be used more widely.

Description

Vertical compound strike-back hammer crusher

The utility model relates to a kind of breaker, a kind of vertical compound counter beating hammer type disintegrator of more specifically saying so.

The vertical hammer mill of people's use at present exists following some deficiency, and the wear extent of (1) tup is big; (2) wear liner is very serious; (3) discharging-material size is inhomogeneous, and the classification phenomenon is obvious especially, thereby upright broken use face is restricted.

A kind of vertical impact mill is disclosed on the Chinese patent communique, the patent No.: 89206333.5, utilize the counterpunch board on the fixed rotor that material is hit, the counterpunch board counterattack, thus material is carried out fragmentation.This vertical impact mill is to being had certain requirement by the granularity of broken material, and crushing is not high in addition, and the material that fragmentation goes out is inhomogeneous.

The purpose of this utility model is to have designed a kind ofly to less demanding by broken raw meal particle size in order to overcome above-mentioned prior art weak point, and discharging-material size is even, the vertical compound counter beating hammer type disintegrator that tup and wear liner amount are little.

The purpose of this utility model can realize in the following manner: a kind of vertical compound counter beating hammer type disintegrator, include cylindrical shell, be mounted with liner plate on its inwall, between every up and down row's liner plate dividing plate is arranged, the two ends up and down of cylindrical shell are fixed with loam cake and lower cover respectively, on cover and be mounted with feed hopper, under cover and be mounted with hopper, main shaft is placed in the middle part of loam cake and lower cover by bearing, be mounted with successively on the main shaft in cavity on the bottom of the main shaft (9) of cylindrical shell (1) cavity and be mounted with fixed rotor (2) with structure cover (3), on discoid fixed rotor (2) sidewall projection is arranged, form hammer carrier (16), be fixed with peening hammer plate (17) on it, be mounted with pallet (15) on the upper surface of fixed rotor (2), main shaft (9) at fixed rotor (2) upside upward is set with four hammer dishes (7) by distance, on, under per two hammer dishes (7) between be mounted with row's tup (6) respectively with bearing pin (8), part on the main shaft (9) is with hold-down nut (10) axial location.

The utility model compared with prior art has following advantage: still employing activity hammer is broken in (1) I and II fragmentation, makes the particle size restrictions of being broken material not strict, and employing activity hammer, and the utilization rate of tup is doubled; (2) material after third level fragmentation adopts fixed rotor and arrangement beater plate thereon to the I and II fragmentation carries out grinding, thereby can guarantee that discharging-material size is even; (3) because the high speed rotating of fixed rotor forms downward negative pressure in its whole chamber,, thereby make the complete machine fragmentation alleviate pollution to environment so airborne dust is less.

Description of drawings:

Accompanying drawing 1 is a structural front view of the present utility model.

Accompanying drawing 2 is structural representations of the utility model fixed rotor.

The utility model is described in further detail with reference to the accompanying drawings:

Shown in accompanying drawing 1: a kind of vertical compound counter beating hammer type disintegrator, include cylindrical shell 1, cylindrical shell 1 adopts combined type, on cylindrical shell 1 inwall, be fixed with liner plate 4, on, 4 of every row's liner plates are fixed with dividing plate 5 down, the two ends up and down of cylindrical shell 1 are fixed cover 12 and lower cover 13 respectively, be mounted with feed hopper 11 on the loam cake 12, the downside of lower cover 13 is mounted with hopper 14, the lower end of main shaft 9 is placed in the middle part of lower cover 13 by self-aligning bearing, the top of main shaft 9 is placed in the middle part of loam cake 12 by self-aligning bearing, the downside of the main shaft 9 in cylindrical shell 1 is equipped with fixed rotor 2 by structure cover 3, and shown in accompanying drawing 2: described fixed rotor 2 external forms are in the form of annular discs, and some projectioies are arranged on the wall of its disk, form hammer carrier 16, on hammer carrier 16, be fixed with and hit bar 17.Be mounted with pallet 15 in 2 sections upper surfaces of fixed rotor, the material that falls thereon is thrown on the liner plate 4 by action of centrifugal force, on the main shaft 9 of fixed rotor 2 upsides, be set with four hammer dishes 7 by distance, settle tup 6 with bearing pin 8 respectively on each hammer dish 7 up and down, thereby constituted the two-stage hammer crushing, on arrange tup 6 and lack one times than following row's tup 6 numbers.Part on the main shaft 9 comes axial location by hold-down nut 10.Upper end at main shaft 9 is mounted with belt pulley.
