Description
Technical field
The utility model relates to hammer crusher, especially a kind of moving double shear formula hammer crusher of surely hammering into shape.
Background technology
At present, existing hammer crusher is comprised of parts such as body, rotor, hammer leaf, sieve, pressure screen frame, tight cribellum, motor usually.During work, by motor drives rotor high-speed rotation, by being installed in the high linear speed motion of epitrochanterian hammer leaf, the crushing material that will come in from charging aperture.Material reaches certain fineness through pulverizing, and is discharged by the mesh of sieve.But crushed work efficient is not high.And shear hammer sheet crusher, be outside the hammer mill rotor circumference, sieve decides hammer grillage and fixed hammer with interior having set up.High linear speed with hammer leaf pulverize with hammer leaf with near compass screen surface decide the hammer shear action, improving output, reducing and certain advance is being arranged aspect the energy consumption.Yet in reality use operating process, find: surely hammer the radially wide of plate into shape, formed radially-directed for the bump loop of material and compass screen surface, the axial crisscross motion of material is hindered, reduced crush efficiency; And increase the weight of wearing and tearing to screen cloth, shortened service life of equipment; A large amount of extra electric weight have been expended.Increased maintenance and production cost, labour intensity is larger.
In view of the foregoing, the existing moving scissors pulverizer of surely hammering into shape needs to improve.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of moving surely to hammer double shear formula hammer crusher into shape, make the staggered smooth and easy operation of percussion movement of the material of pulverizing, increasing material by hammer leaf and the fixed number of times of shearing of hammering into shape; Significantly improve crush efficiency, and reduce material to the wearing and tearing of screen cloth, extension device service life; Save a large amount of electricity and production cost, greatly reduce labor intensity.
The utility model is in order to realize above-mentioned purpose, adopt following technical scheme: a kind ofly moving surely hammer double shear formula hammer crusher into shape, be by: crusher body, bearing block, axial admission cover, rotor plate, hammer leaf, charging aperture, double shear hammer surely that plate, interior ring are hammered into shape surely, outer shroud is decided hammer into shape, sieve, safety guard, shaft coupling, motor, door closure, pressure screen frame, rotor main shaft consist of; The place ahead of crusher body be symmetrical arranged bearing block corresponding to the rear arranges rotor main shaft in the bearing block; The rear of crusher body arranges motor, the coaxial shaft coupling that arranges between motor and the rotor main shaft, and shaft coupling arranges safety guard outward;
The coaxial uniform row's rotor plate that arranges on the rotor main shaft, the double shear that is coaxially set between the adjacent rotor plate is hammered plate surely into shape, and double shear is surely hammered into shape between plate and the rotor plate hammer leaf is set; The periphery that double shear is hammered plate surely into shape arranges the cylindrical shape sieve, and the sieve periphery arranges the pressure screen frame, and the two is arranged in the inner chamber of crusher body to press screen frame and sieve.
The top of crusher body arranges charging aperture, and the both sides of crusher body arrange door closure; The front and back of crusher body arrange axial admission and cover on the bearing block inboard.
Double shear is surely hammered at least three outer shrouds of the uniform setting of plate external diameter into shape and is surely hammered into shape, and double shear is hammered the fixed hammer of ring at least three of the uniform settings of plate internal diameter surely into shape, and interior ring is surely hammered into shape with outer shroud and surely hammered interlaced setting into shape.
Technological work principle of the present utility model is:
Surely the plate inner and outer ring of hammering into shape of the present utility model respectively is provided with respectively 6 interlaced ledges, is respectively namely that interior ring is hammered into shape surely, outer shroud is hammered into shape surely.The peen that interior ring is hammered into shape surely is apart from rotor diameter 5-10mm, during in order to rotor without interference.The peen that outer shroud is hammered into shape surely and sieve are apart from 16-20mm, in order to material and sieve bump bounce-back crisscross motion.
Interior ring is hammered into shape surely, outer shroud is hammered into shape surely with surely hammering plate into shape is an integral body, adopts the high-quality steel, and two sides that inner and outer ring is hammered into shape surely and end face tungsten carbide spray welding are to improve abrasion resistance and the shear strength of deciding hammer.Only need after the wearing and tearing get final product with the tungsten carbide spray welding reparation deciding the hammer desired area, surely hammer the looseness fault of hold-down screw with the elimination assembly type into shape.
Surely hammer plate top into shape, the bottom is stiff end, can fix with body.
Surely the quantity of hammering plate into shape described in the utility model is that the quantity of rotor plate deducts 2.Its mounting means is: except 2 rotor plates of rotor axial initial and end, surely hammer plate and the concentric corresponding installation of rotor plate into shape for every, and make and decide hammer plate and rotor plate two axial end faces in one plane.Surely the distance of hammering the axial distance of plate and hammer leaf and rotor plate and hammer leaf into shape is identical, is generally 10-50mm, can adjust the relative length of hammer leaf two ends spacer, adjusts the spacing distance of hammer leaf and fixed hammer.
The shearing angle that hammer leaf when running and fixed hammer meet, interior ring are surely hammered into shape and are that 9-10 ° of degree, outer shroud are hammered into shape surely and are 13-15 ° of degree, are more conducive to shear and to the thrust of material to the compass screen surface direction.Fixed hammer is inside and outside interlaced arrangement deciding the hammer plate, thus when turning round, hammer leaf just formed inside and outside twice shearing, therefore be double-shear.
The wide space of 45 ° of angles 35 is arranged, so that the bump of material and crisscross motion increases material by hammer leaf and the fixed shearing number of times of hammering into shape between fixed hammer and the fixed hammer.When shearing material, material there is outside thrust, therefore can significantly improve crush efficiency, and reduce material to the wearing and tearing of screen cloth, prolong screen life-span.
The beneficial effects of the utility model are: simple and compact for structure, reasonable in design, manufacture easily, and easy to use, handling safety is quick; Make the staggered smooth and easy operation of percussion movement of the material of pulverizing, increase the number of times that material is sheared by hammer leaf and fixed hammer; Significantly improve crush efficiency, and reduce material to the wearing and tearing of screen cloth, extension device service life; Save a large amount of electricity and production cost, greatly reduce labor intensity.
The utility model saving of labor, save time, laborsaving; Greatly reduce maintenance and maintenance cost, easy to maintenance.Invest lowly, be convenient to promote.Satisfying the market and user's demand.
