Abstract

The utility model provides a double-hammer ring type crusher, relating to a hammer crusher, and aiming at solving the problems of poor crushing efficiency and hammer wear of the prior art. The double-hammer ring type crusher comprises a frame, a housing, sieve plates, and a crushing mechanism arranged in the housing and drive mechanisms, wherein the housing comprises an upper housing and a lower housing, a discharge hole of the upper housing and a feed inlet of the lower housing are communicated with each other, the upper housing and the lower housing are respectively provided with a set of crushing mechanism, the frame is fixed with the drive mechanisms respectively corresponding to the upper housing and the lower housing, and the mesh of the sieve plate in the upper housing is larger than that of the sieve plate in the lower housing. Compared with the prior art, the double-hammer ring type crusher crushes materials by two times by virtue of two sets of crushing devices mutually communicated up and down, can prevent the hammer in the upper housing from wearing quickly, and simultaneously can crush the materials into smaller sizes.

Description

Dual hammer ring crusher

Technical field

The utility model relates to a kind of breaker, is specially a kind of hammer mill.

Background technology

The hammer mill that uses comprises frame at present, the casing and the motor pulley that have charging aperture, casing is contained on the frame, casing inside is crusher chamber, bearing block is equipped with in both sides in frame, on the bearing of bearing block, main shaft is housed, motor pulley is contained in an end of main shaft, on the main shaft in the casing at least two quartering hammer reels are housed, two quartering hammer axles are housed on the quartering hammer reel at least, quartering hammer all is housed on the every broken shaft, in the bottom of frame the discharging sieve plate is housed, the other end at main shaft also is equipped with inertial flywheel, material falls the crusher chamber that enters in the casing from the hammer crushing machine inlet capable, clashes into mutually with the quartering hammer of at a high speed rotation and is broken, and the material after the fragmentation drops on the sieve plate of certain interval.Quartering hammer except on crusher chamber top with the material that continues to fall clashes into mutually, also to the material that the crusher chamber bottom is deposited on the sieve plate be imposed bump, roll, force to be broken afterwards that satisfactory tiny material draws off by sieve plate.At present the hammer mill that uses has only a crusher chamber, and crumbling method is based on the bump of quartering hammer to material, the tup serious wear, and be not easy material is broken into granule, crushing efficiency is not high.

Summary of the invention

For solving crushing efficiency difference and the tup wear problems that exists in the prior art, the utility model provides a kind of dual hammer ring crusher.

The technical solution adopted in the utility model is: a kind of dual hammer ring crusher, comprise frame, be fixed on the casing that has charging aperture and discharging opening on the frame, be contained in the sieve plate of bottom of shell discharging opening, be contained in crushing mechanism in the casing and the transmission mechanism that is in transmission connection with crushing mechanism, described transmission mechanism comprises the main shaft on bearing block that is fixed on the frame both sides and the bearing that is contained in the bearing block, one end of main shaft is equipped with motor pulley, the other end is equipped with inertial flywheel, described crushing mechanism comprises the quartering hammer reel that is contained on the main shaft, be contained in the quartering hammer axle on the quartering hammer reel and be contained in quartering hammer on the quartering hammer axle, described casing comprises upper casing and lower casing, the discharging opening of upper casing and the feeding inlet of lower casing, one cover crushing mechanism is housed respectively in upper casing and the lower casing, be fixed with respectively upper casing and the corresponding transmission mechanism of lower casing with casing on the frame, the sieve plate gap in the upper casing is greater than the sieve plate gap in the lower casing.

After material enters from dual hammer ring crusher upper casing charging aperture, clash into mutually with the quartering hammer of at a high speed rotation and by primary fragmentation, material after the fragmentation falls into the crusher chamber of lower casing after by the upper casing sieve plate, in lower casing material being carried out secondary pulverizes, and on the lower casing sieve plate to the material inertia impact, make it become tiny material and draw off by sieve plate.

Compared with prior art, the hammer mill that the utility model provides carries out twice fragmentation by the two cover breakers that communicate up and down to material, can make the tup in the upper casing can not cross quick-wearing, and material can be broken into littler specification.

Description of drawings

Fig. 1 is the structural representation of the dual hammer ring crusher of the utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Among the figure, the 1-frame; The 2-sieve plate; The 3-bearing block; The 4-main shaft; The 5-motor pulley; The 6-inertial flywheel; 7-quartering hammer reel; 8-quartering hammer axle; The 9-upper casing; The 10-lower casing; The broken tup of 11-stairstepping; The 12-edge is the disk quartering hammer ring of sawtooth; The entire disk quartering hammer of 13-ring.

The specific embodiment

A kind of dual hammer ring crusher that the utility model provides, comprise frame 1, be fixed on the casing that has charging aperture and discharging opening on the frame 1, be contained in the sieve plate 2 of bottom of shell discharging opening, be contained in crushing mechanism in the casing and the transmission mechanism that is in transmission connection with crushing mechanism, described transmission mechanism comprises the main shaft 4 on bearing block 3 that is fixed on the frame both sides and the bearing that is contained in the bearing block 3, one end of main shaft 4 is equipped with motor pulley 5, the other end is equipped with inertial flywheel 6, described crushing mechanism comprises the quartering hammer reel 7 that is contained on the main shaft 4, be contained in the quartering hammer axle 8 on the quartering hammer reel 7 and be contained in quartering hammer ring on the quartering hammer axle 8, described casing comprises upper casing 9 and lower casing 10, the feeding inlet of the discharging opening of upper casing 9 and lower casing 10, one cover crushing mechanism is housed respectively in upper casing 9 and the lower casing 10, be fixed with respectively the transmission mechanism corresponding with the upper casing 9 of casing and lower casing 10 on the frame, the sieve plate gap in the upper casing 9 is greater than the sieve plate gap in the lower casing 10.

At least connect two quartering hammer reels 7 on the every main shaft, the length and the motor power (output) of its quantity and main shaft 4 are relevant, the quartering hammer quantity that connects on each quartering hammer reel 7 depends mainly on the size of quartering hammer, quartering hammer is too big or too little, be unfavorable for that all disintegrating machine brings into play its performance, therefore, preferred scheme is evenly to connect three quartering hammer axles on each quartering hammer reel 7.

The quartering hammer that is contained in the upper casing 9 is the broken tup 11 of the little stairstepping in the big rear end of front end, and the quartering hammer that is contained in the lower casing 10 is a disc quartering hammer ring.The purpose of She Zhiing is mainly clashed into the broken tup in the upper casing like this, and the quartering hammer ring in the lower casing mainly impacts.

The efficient that rolls for quartering hammer ring in the further raising lower casing, disc quartering hammer ring in the lower casing 10 is divided into disk quartering hammer ring 12 and the entire disk quartering hammer ring 13 that the edge is a sawtooth, the quartering hammer annular shape that is contained on the same quartering hammer reel is identical, and two kinds of not quartering hammer rings of similar shape dress are housed respectively on adjacent two quartering hammer reels.The edge is that 12 pairs of big slightly materials of disk quartering hammer ring of sawtooth carry out punching press and bump, and 13 pairs of less materials of entire disk quartering hammer ring roll.
