Description

Revesible-and hammer-type fine pulverizer with single rotor
A kind of horizontal single rotor reversible hammer slimer that on arc side plate, is equipped with the step liner plate.
Existing beater grinder power consumption is higher, and concentrated wear is bigger, and maintenance is frequent, labour intensity is very big and dust pollution is serious." crushing and screening principle and equipment " (metallurgical industry publishing house) provides φ 1430 * 1300mm reversible beater grinder for the 174th page.The rotor of this pulverizer is made up of main shaft, disk, tup etc., several disks of dress on main shaft, hang several tups by bearing pin between per two disks, the main shaft two supports is on rolling bearing pedestal, and motor directly drives the rotor revolution by elastic coupling.The arc side plate upper end that is symmetrical in the rotor both sides is suspended on the axle that is fixed on the casing two side, and the lower end is bearing on the eccentric wheel.The discharge grid section is fixed on the arc side plate, and its gap is generally 40,80,120mm.Rotate eccentric wheel, just can regulate the gap between tup and grid section, thereby guarantee required product granularity.This kind size reduction machinery productivity ratio height, the ratio of reduction is big, product granularity is even, cross to pulverize few, but tup, grid section, liner plate, rotor discs wearing and tearing are very fast, wearing and tearing are faster during particularly broken harder material.When the moisture of the material that is broken surpasses 12% or when containing clay, the slit of grid section is stopped up easily, thereby reduces productivity ratio, and increases the abrasion of parts such as energy consumption and tup.
The purpose of this utility model is improved existing horizontal single rotor reversible beater grinder, especially arrange to pulverize on hammer and the arc side plate by certain requirement the step liner plate is set, be used for hit back fragmentation and grinding of material has been improved the performance of pulverizer.
Realize that the purpose of this utility model adopts following approach: on rotor, be provided with the hammer dish, some rows that are parallel to horizontal axis are arranged and perpendicular to the row of horizontal axis, every row is provided with n(n 〉=3) individual pulverizing hammer, two pulverize and are spaced apart n-1 row or row between the hammer on each level row or vertical row.In addition, have at least two to pulverize stagger hammer out row or a row's diagonal angle of hammer and adjacent level row or the pulverizing on the vertical row and arrange on each level row, the vertical row.Be symmetrical in the rotor both sides and be provided with arc side plate, its top is the counterattack zone, and the bottom is an abrasive areas, respectively is equipped with step liner plate inequality.
By being modified into seamless step counterattack grinding liner plate in the reasonable arrangement on the keyboard and with the grid section on the arc side plate to pulverizing hammer, make the utility model novel structure, functional, concentrated wear is less, easy to maintenance, have make that material smashes, the combined characteristic of impact crushing and grinding, starting current and power consumption have been reduced, the pure dirt that alleviates in the crushing process flies upward, blockage phenomenon not, reduced labour intensity and the loss of maintenance steel, thereby practical productivity is improved.

Fig. 5 is the utility model step lining plate structure figure.
In the accompanying drawings: the 1-discharging opening, the 2-base, 3-arc side plate lash adjusting device, 4-step liner plate, the 5-arc side plate, 6-hammer dish, 7-pulverizes hammer, the 8-main shaft, the 9-charging aperture, the 10-casing, 11-arc side plate supporting arrangement, the 12-bearing pin, the 13-bearing, the 14-bearing pin, 15-nickel inscription alloy-layer, the 16-tup, the 17-hammer stem, 18-hammers tail into shape, the straight step liner plate of 19-, 20-strikes back liner plate, 21-grinds liner plate, 22-strikes back the zone, the 23-abrasive areas, 24-bends the step liner plate, the short adjacent side of 25-, 26-step angle, the long adjacent side of 27-.
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.
The root diameter of most preferred embodiment described in the utility model is that 800mm, axial length are 500mm, and by the motor-driven of 55KW, the rotating speed of rotor is that per minute 1244 changes, and linear velocity is per second 52m.The two supports of rotor main shaft 8 is on rolling bearing 13, and the central area of main shaft 8 is fixed with 10 hammer dishes 6, and hammer rim disc center circumferential has 12 onesize pulverizing hammer fixing holes.Per two hammer dishes 6 hang 4 by bearing pin 12 and pulverize hammer 7, and whole rotor hangs with 36 altogether and pulverizes hammer.Its arrangement architecture is as follows: on rotor, be referred to as row along the straight line that is parallel to horizontal axis lateral arrangement pulverizing hammer 7, arrange vertically that perpendicular to horizontal axis the camber line of pulverizing hammer 7 is referred to as to be listed as between the two hammer dishes 6, then every row is provided with n(n 〉=3) individual pulverizing hammer 7.Listing two in each row or each pulverizes and is spaced apart n-1 row or row between the hammer 7; Have at least two pulverizing hammers 7 to arrange with the 7 one-tenth diagonal angles that are listed as that stagger of pulverizing hammer on the adjacent row on each row, each lists has at least two pulverizing hammers 7 to arrange with the 7 one-tenth angles of arranging of staggering of pulverizing hammer on the adjacent column.
Be symmetrical in the camber side plate 5 on rotor both sides, the upper end is suspended on the arc side plate supporting arrangement 11 on casing 10 two sides, the lower end is bearing on the arc side plate lash adjusting device 3, the handle that rotates on the arc side sheet room clearance adjustment apparatus just can be regulated the distance of pulverizing between hammer 7 and the arc side plate 5, thereby adjusted material and pulverized the gap of passing through, made product granularity keep stable exponential quantity always.
Arc side plate 5 is made of some blocks of step liner plates 4.Step liner plate 4 can be divided into curved step liner plate 24 and straight step liner plate 19, and 25 liang of adjacent adjacent sides in step angle of curved step liner plate 24 are made short adjacent side 26 and long adjacent side 27 respectively.Be step liner plate 19 always on 22 tops, the counterattack on arc side plate 5 tops zone, all the other by short adjacent side 26 last, long adjacent side 27 under 20 some compositions of counterattack liner plate of curved step liner plate 24 formations; The abrasive areas 23 of arc side plate 5 bottoms, by long adjacent side 27 last, short adjacent side 26 under 21 some compositions of grinding liner plate of constituting of curved step liner plate 24.
In order to enhance productivity, reduce wear, maintain easily, pulverize hammer 7 and form by tup 16, hammer stem 17 and hammer tail 18.Tup 16 is connected with hammer stem by bearing pin 14, can fix or shirk.The upper end of tup 16 is equipped with the nickel inscription alloy-layer 15 that forms through built-up welding, to increase the intensity of pulverizing hammer 7.
When pulverizer was worked, material was fed in the machine by charging aperture 9, met with the pulverizing of high speed rotary hammer 7 immediately, and was impacted and pulverize.Breaked material obtains kinetic energy from pulverizing hammer 7, impacts with the counterattack liner plate 20 of very big speed on the arc side plate 5 of casing inner wall in counterattack regional 22 and suffers to pulverize for the second time.After this, the less material of granularity drops down onto on the grinding liner plate 21 that grinds territory district 23, be subjected to pulverizing hammer 7 additional impact and its tup 16 with grind liner plate 21 do strong shear grind broken, at this moment, bigger material rebounds and pulverizes in the tracks of hammer 7 rotations, continues to be subjected to pulverizing the impact of hammer 7 and pulverizes.In addition, in the material crushing process, the impact comminution between the material is arranged also.Through impact comminution with the material after grinding, under the dynamic action of pulverizing hammer 7, fall to discharging opening 1 along grinding liner plate.
Through experiment, the described pulverizer feed size of present embodiment is general≤25mm, discharging-material size≤3mm, production capacity per hour can reach 30~50T(coal), electrical energy consumption per tonne of raw coal≤2KW can save abrasion steel 60%.
