Abstract

The utility model discloses a reversible reaction-type fine crusher rotor which comprises a spindle. The spindle is provided with a plurality of hammer disks along the axial direction; more than ten hammer shafts of which the number is an even number are vertical to the hammer disks and are uniformly arranged in the peripheral direction of the hammer disks; hammer handles are vertically inserted on the hammer shafts and are fixed together with the hammer disks; hammer heads are fixed on the hammer handles; the hammer heads of which the number is half of that of the hammer shafts are uniformly distributed on each hammer disk in the peripheral direction; and the hammer heads on each two adjacent hammer disks are distributed in a staggered mode along the axial direction of the spindle. The reversible reaction-type fine crusher rotor has the beneficial effects that the small hammer disks design is adopted; the hammer heads are fixed on the hammer handles; the hammer handles are inserted on the hammer shafts in a crossed mode; the diameter of the outer edge of each hammer disk is smaller than that of the outer edge of a hammer disk in the big hammer disk design by at least 40 percent; the outer edges of the hammer disks do not need to be subjected to build up welding of wear resistance materials, so that the cost and the operation maintenance cost of the rotor are saved.

Description

Reversible reaction type fine crusher rotor

Technical field

The utility model relates to the rotor of reversible reaction type fine crusher.

Background technology

The technical scheme of the rotor of reversible reaction type fine crusher and defective in the prior art:

1, sledgehammer dish design, hammer dish outer rim is near tup part capable of using, and hammer dish outer rim need be done the built-up welding of high-abrasive material, and periodic hammer dish needs repair welding to safeguard, needs more exchanging rotor hammer dish during heavy wear, increases rotor cost and operation maintenance cost;

2, hammer dish circumferencial direction is pressed the disintegrating machine sized and is arranged 4～12 hammer axles, and tup arranges that density is low, and tup is big, Heavy Weight, and undesirable when the particle diameter of fragmentation≤10mm requires, the utilization rate of tup is also low;

If 3 the adjustment tups need put in order tease and ridicule whole, inconvenience.

The utility model content

The utility model technical problem to be solved just provides a kind of reversible reaction type fine crusher rotor, and is simple in structure, with low cost, and the utilization rate of tup is high.

For solving the problems of the technologies described above; The utility model adopts following technical scheme: reversible reaction type fine crusher rotor; Comprise main shaft, main shaft is installed some hammer dishes vertically, it is characterized in that: said hammer dish circumferencial direction is evenly arranged more than ten perpendicular to the hammer dish and is the hammer axle of even number; Hammer handle vertically is arranged in the hammer axle and goes up and fix with the hammer dish, and tup is fixed on the hammer handle.

As preferably, 12～18 hammer axles of said hammer dish circumferential directions.

As preferably, circumferentially evenly the distribute tup of half quantity of hammer axle of each hammer dish upper edge is along the axially interleaved distribution of tup on the adjacent two hammer dishes of main shaft.

As preferably, the length of said hammer handle between hammer dish and tup is 1～1.5 times of tup length.

The beneficial effect of the utility model is:

1, hand hammer dish design, tup is fixed on the hammer handle, and hammer handle intersects and is through on the hammer axle, and to when young 40%, hammer dish outer rim need not to do the built-up welding of high-abrasive material to hammer dish external profile diameter, thereby has saved rotor cost and operation maintenance cost than the design of sledgehammer dish;

2, hammer dish circumferencial direction is pressed the fine crusher sized and is arranged 12～18 hammer axles, and tup arranges that density is big, and tup size to fit, weight are moderate, and satisfactory for result when the particle diameter of fragmentation≤10mm requires, the utilization rate of tup is also high;

3, the design of hammer handle makes two tup adjustment of single group symmetry become possibility, realizes arranging by the convenient adjustment of output requirement tup, when the owner requires to reduce production capacity, reduces power consumption, to reach purpose of energy saving.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model side view.

The specific embodiment

Extremely shown in Figure 2 like Fig. 1; Be the reversible reaction type fine crusher of the utility model rotor; Comprise main shaft 1, main shaft is installed some hammer dishes 2 vertically, and said hammer dish circumferencial direction is evenly arranged more than ten perpendicular to the hammer dish and is the hammer axle 3 of even number; Hammer handle 4 vertically is arranged in the hammer axle and goes up and fix with the hammer dish, and tup 5 is fixed on the hammer handle.12～18 hammer axles of said hammer dish circumferential directions.The tup of circumferential half quantity of hammer axle that evenly distributes in each hammer dish upper edge is along the interleaved distribution of tup on the axial adjacent two hammer dishes of main shaft.The length of said hammer handle between hammer dish and tup is 1～1.5 times of tup length.

Form: form by bearing cap 63, bearing block 6, bearing 61, main shaft, hammer dish, end plate 21, hammer axle, hammer handle, tup, baffle plate 11, stifle 62 and bolt and nut etc.Rotor integral body is installed some hammer dishes on main shaft, two ends are end plate, is fixed on the main shaft with baffle plate and contract key, and hammer dish circumferencial direction is pressed the fine crusher sized and arranged 12～18 hammer axles, and hammer handle intersects to be through to be hammered into shape on the axle, and tup is fixed on the hammer handle.The rotor arrangement two ends link through bearing and bearing cap, bearing block and securing member and fine crusher casing pedestal base.

Claims
