Description

Vertical impact-hammer type disintegrator

The utility model relates to a kind of vertical beater type disintegrating machine, belongs to materials crusher tool technical field.

Present known hammer mill, impact breaker (horizontal) is arranged, vertical-spindle hammer crusher or the like, these disintegrating machines all are to utilize the tup of rotation at a high speed to hit and the milling material, make material reach certain fineness, but there is a common shortcoming in they, it is low to be that material is subjected to the frequency of impact grinding in cylindrical shell, the corresponding ratio of reduction is little, efficient is low, the consumable accessory wear block, West Germany KHD company once developed a kind of Tandem mill and replaced ball mill with hammer mill (cement technology 1991), had obtained the effect that reduces power consumption, but owing to be subjected to the restriction of structure, this disintegrating machine is easy to wear.The disclosed vertical impact hammer mill of CN 2107313U has been done significant improvement to the material crushing technology, this machine carries out hammering, washes away the material of being strikeed back by counterpunch board again after penetrating from the pallet upthrow, be discharged from cavity at last, have low in energy consumption, characteristics such as simple in structure, but two rotors and corresponding tup layout thereof are reasonable inadequately in the cylindrical shell, do not form tangible two crushed zones, have influenced crushing effect and have further improved.

The purpose of this utility model provides a kind of material and be subjected to impact grinding frequency height in cylindrical shell, and rotor and corresponding tup are rationally distributed, the vertical beater type disintegrating machine that the consumable accessory wearing and tearing are few.

Order of the present utility model is achieved in that a kind of vertical beater type disintegrating machine comprises motor, belt, belt pulley, cylindrical shell in a tubular form, its two ends link with loam cake and base respectively, the lower end of stair-stepping main shaft is fixed on the bearing arrangement of base, its upper end is fixed in the loam cake mesopore by bearing arrangement, on cover and also be fixed with feed hopper, the lower end of base is fixed with hopper, and be fixed on counterpunch board parts in addition on the cylinder inboard wall, it is characterized in that being fixed on rotor (comprising corresponding tup) longitudinal length on the main shaft (on, height down) is significantly shorter than lateral length (from the main shaft limit between the tup top of cylinder inboard wall direction length), every sieve plate cylindrical shell obviously is divided into impact grinding zone and the broken crushed zone of hammer by " L " type that is fixed on the nearly middle part of cylinder inboard wall.

This is practical following advantage:

1, kept outside vertical impact hammer mill the advantage, and increased milling and grind fragmentation projectile impact, counterattack, hammering, the comprehensive crumbling method that washes away.

2, by barrel space obviously being divided into two fracture area, increased frequency of impact and abrasive action, made material reach thinner every sieve plate.

3, this machine is simple in structure, and the consumable accessory wearing and tearing are few.

Description of drawings:

Accompanying drawing 1 is the utility model broken segment structural representation.

1, belt pulley 2, main shaft 3, loam cake 4, cylindrical shell 5, counterpunch board (I) 6, tup or bar 7, every sieve plate 8, counterpunch board (II) 9, tup 10, comb sieve plate 11, base 12, hopper 13-1 and 13-2 rotor 14, broken crushed zone 15-1 of hammer and 15-2 batch mixing pan 16, impact grinding zone 17, feed hopper

The utility model is described in further detail with reference to the accompanying drawings, and the main shaft of vertical beater type disintegrating machine (2) upper end is connected with motor by belt pulley and V belt; The external form of cylindrical shell in a tubular form, on it, the lower end connects loam cake (3) and base (11) respectively, inboard fastening counterpunch board of cylindrical shell (5) and counterpunch board (8), the top and bottom of main shaft are placed in the mesopore of loam cake (3) and the central part of base (11) by bearing arrangement respectively, be fixed on two rotor (13-1 on the main shaft, 13-2) and be fixed on these two epitrochanterian tups (6, longitudinal length 9) (on, height down) is significantly shorter than lateral length, below rotor (13-2) and tup (9) keep closely with inverted "L" shaped comb sieve plate (10), to strengthen milling and abrasive action to material, be fixed on the nearly middle part of cylinder inboard wall every sieve plate (7), it obviously is divided into impact grinding zone (16) and the broken crushed zone (14) of hammer to cavity, the impact grinding zone can be provided with 1-3, the impact grinding zone is by counterpunch board (5), every sieve plate (7), with the fixing batch mixing pan (15-1) of rotor (13-1), reaching tup or bar (6) forms; The broken crushed zone (14) of hammer is made up of counterpunch board (8), comb sieve plate (10), batch mixing pan (15-2) and tup (9).The inner surface of counterpunch board (5) is the tooth ripple shape, with tup or bar (6) opposite position, and along tup (or bar) rotation direction one strip projected parts is arranged, and its effect is to intercept coarse fodder, strengthens broken.The inner surface of counterpunch board (8) also is the tooth ripple shape, and comb sieve plate (10) cross section is down " L " shape, and its surface is corrugated, and has up-small and down-big comb seam hole; Also be " L " type every sieve plate (7) cross section, they all use bolt and cylindrical shell (4) inwall fastening, and batch mixing pan (15-1) is (15-2) in the form of annular discs, and its upper surface has strip projected parts, and it and tup (6,9) fasten as one with rotor (13) respectively.

The course of work is: start motor, main shaft rotates, material is entered on the batch mixing pan of cylindrical shell by feed hopper (17) by deadweight, it is gone up to counterpunch board (5) by impelling and impacts mutually with counterpunch board (5), material is subjected to be subjected to tup or bar (6) hammering again after counterpunch board (5) counterattack, fly to once more on the counterpunch board (5), this form of degree n n repeatedly circulates, last material is being gone up the formation accumulation every sieve plate (7), washing away of the material that fly bomb came when the material in the accumulation constantly was subjected to impact grinding, the fines good fluidity, from windrow, be slipped to earlier on the batch mixing pan (15-2) of another broken crushed zone (14) of hammer, be subjected to a series of impelling again, counterattack, hammering, and milling, abrasive action, qualified material is forced to discharge cavity through the comb hole.
