Description

A kind of drying crusher with unique anti-tup dropping structure and feeding-distribution device
Technical field is a kind of to integrate oven dry and the disintegrating machine of pulverizing, and is specifically designed to handle that moisture is higher, quality is softer and the raw material of non-abrasive quality.Be specially adapted in the manufacture of cement in the wet grinding and dry burning technical process oven dry of raw material slip filter cake and break up.
The main in the world manufacturer of its technical of technical background drying crusher comprises Denmark FL.Smidth company and German KHD company.During such disintegrating machine work, high-temperature gas (~650 ℃) is entered by the air inlet of material gas tank body, and meanwhile, the slip filter cake of water content≤25% also enters disintegrating machine by the charging aperture of material gas tank body.In material gas tank body, the slip filter cake of low temperature mixes with high-temperature gas, and the moisture on slip filter cake surface is dried rapidly, forms dry tack free, a moistening piece filter cake of inside, and gas temperature also drops to about about 300 ℃.Filter cake falls in material gas tank body naturally.In dropping process, the filter cake of bulk is cleaved into more fritter after striking on the branch charge bar that distributes in a triangle, because of the increase of surface area is further dried.After arriving broken cavity, become block filter cake to be dispersed as powdery, when filter cake is broken up, because the material table area increases greatly by high speed rotor rotated tup, moisture is also further dried under the effect of high-temperature gas, and gas temperature also is reduced to about 180 ℃.The material of being broken up, drying leaves drying crusher along the feed box body under the drive of gas.After having as yet the broken filter cake of breaing up leave crusher chamber, crusher chamber was fallen back in bounce-back after a part struck counterpunch board, and a part is directly got back in the crusher chamber under the effect of gravity, so circulation broken, dry, up to its reach condition can by the air-flow band from till.Material can further be dried in the discharging casing, when material leaves drying crusher, and its water content≤1%.
The most important member of drying crusher is a rotor, and it is a revolving body (n ≈ 250r/min) that rotates at a high speed at work, is fixed on the base.Many row's tups are arranged on general such crusher rotor, and every row has some tups.Wherein, the tup that is positioned at every row two ends is " end tup ", and remaining is called for short tup.In the rotating while of whole rotor, be attached to epitrochanterian tup and also will produce gyration during material: when fracture area is run into material with respect to rotor in counterattack, act on object and it is broken up by inertia force, under the reaction force of this power, relative rotation backward takes place simultaneously; After waiting to cross fracture area, tup is returned to the home position again under action of centrifugal force.So process is gone round and begun again, and then tup is ceaselessly being done repeatedly a gyration with respect to the hammer axle always.Because tup must regularly replace because of wearing and tearing, the fixing of tup end must be taked dismountable mode again.
The mode of present fixed hammer has a variety of, and a kind of is that all tups are in the same place by hammer axle string with the end tup.The end of hammer axle puts in the hole of hammer dish, supports whole row's tup (comprising the end tup).For preventing hammer axle left and right sides play, used high-strength bolt that block and hammer axle are connected together; Used latch to prevent that bolt from coming off because of rotation at work again.When maintenance, unclamp bolt and can extract the hammer axle out, take off tup.The shortcoming of this structure is: tup be subjected at work interrupted, irregular, from the power of indefinite direction, correspondingly will be with its stressed acting on the hammer axle.So, the hammer axle comprises generation that inclination is (because of the gap causes at work, angle is very little, but effect repeatedly for a long time), phenomenons such as left handed twist, right play, and these power are all born by the cross section of high-strength bolt after all, after the work of certain section time, this bolt will bear alternate stress repeatedly because of single cross section and rupture.In the production process of reality, although this bolt has been done as much as possible to strengthen, but still repeatedly rupture, cause spool come off hole on the hammer dish of hammer, cause serious production accident.
Another passes the hammer dish for the hammer axle, and the end tup is fixing outside the hammer dish separately.Be bound up by high-strength bolt and block between end tup and the hammer axle.Gapped between block and the end tup hole so that hold tup freely to turn round.The shortcoming of this structure: the end tup be subjected at work interrupted, irregular, from the power of indefinite direction, this power acts on the set bolt by block.After the work of certain section time, this bolt will bear alternate stress repeatedly because of single cross section and rupture.In the production process of reality, although this bolt has been done to strengthen as much as possible, but still repeatedly rupture, cause the end tup to come off, cause serious production accident.
Another important problem is: the feeding-distribution device that material plays an important role in dropping process.The spout and the height fall between the rotor of drying crusher are very big, generally reach 6~10m.The situation of the lattice wheel feeding that generally adopts now, material are batch (-type), big block feeding.This feeding manner has following adverse effect to disintegrating machine: the dynamic load that batch (-type), big block feeding are subjected to the crusher rotor of rotation is at a high speed impacted sharply and is strengthened; Being block material can not evenly distribute on whole rotor width, makes the tup wearing and tearing inhomogeneous; Rotor load is unbalanced, unstable, to impact increasing of transmission system etc.Also cause efficient to reduce drawbacks such as service life of a machine shortening simultaneously.
The purpose of this utility model, be exactly to solve above two class problems.Obtain the more superior novel drying crusher of effect.
The summary of the invention the present utility model a kind of high efficiency drying disintegrating machine that adopts novel end tup fixed form and novel branch charge bar.This dryer is hammered into shape axles, 16 bolts, 17 protective sleeves, 18 fixture blocks etc. and is formed by 1 discharging casing, 2 air inlets, 3 charging apertures, 4 minutes charge bars, 5 material gas tank bodies, 6 broken cavitys, 7 crusher rotors, 8 end tups, 9 bases, 10 counterpunch boards, 12 tups, 13 tup spacer rings, 14 hammer dishes, 15.11 direction of rotation of representing crusher rotor among the figure.
The novel tup end fixed form that is adopted is as shown in Figure 1: the end of hammer axle (15) opens a gap, and hammer dish (14) top is also corresponding opens a hole, its shape and laying lucky fixture block (18) can being packed into.After fixture block (18) inserts the hole of hammer dish (14), can limit the left and right sides play of hammer axle.Throw out under action of centrifugal force for anti-stop block, adopt bolt (16) that fixture block and hammer dish are connected together.Simultaneously, denuded by material, be provided with a protective sleeve (17) in the outer ring of nut for preventing nut.The characteristics of this mode are: bolt (16) is unconnected with hammer axle (15), and bolt is static in entire work process all the time, relative motion can not take place; Again because block at work, only is subjected to action of centrifugal force always, to bolt can not produce repeatedly yet, the impact of alternation.Therefore, bolt such as can not rupture, become flexible at work at phenomenon, thoroughly stops accidents such as tup comes off.Simultaneously, this structure also is convenient to dismounting, can change tup easily.
The sub-material bar structure that is adopted is seen Fig. 2.Divide charge bar generally to have 3 or more, they generally are made of steel pipe, also can adopt other materials.The diameter that divides charge bar is according to the difference of disintegrating machine specification difference to some extent, generally between Φ 120 to Φ 250mm.Divide charge bar generally to be isosceles triangle and distribute, be fixed on the sidewall of material gas tank body (5), can release from sidewall after the wearing and tearing and change.In disintegrating machine when work, after the branch charge bar (4) that is isosceles triangle and distributes is broken up step by step, can make material more be evenly distributed on the whole disintegrating machine width from the bulk materials of spout (3) feeding, makes the wearing and tearing of tup very even; Simultaneously,, reduced the potential energy of material, thereby alleviated impact, made the rotor running more steady rotor (7) owing to divide charge bar that material is produced active force upwards.Exactly because also this reason makes the transmission of drying crusher change our the direct connection transmission of " motor+reductor " of employing now into by original belt transmission, has improved transmission efficiency.
