Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Usually here in attached drawing description and The component of the utility model embodiment shown can be arranged and be designed with a variety of different configurations.

Fig. 1 is please referred to, the present embodiment provides a kind of twin shaft beater disintegrating machines, are used for including what is be from top to bottom fixedly connected The feeding body 1 of feeding and body 2 is crushed, central position is equipped with feed inlet in the top of feeding body 1, crushes in body 2 Portion is equipped with the pulverizing chamber for comminuting matter, and pulverizing chamber bottom sets that there are two the first grinding rotors for being arranged successively in the horizontal direction 21a and the second grinding rotor 21b, grinding rotor are connect with the driving motor crushed outside body 2 is set to, driving motor and powder Broken rotor uses pin coupler direct-connection transmission, and grinding rotor can forward and reverse work.Further, the first grinding rotor 21a with Second grinding rotor 21b is symmetrical arranged about the central axes of pulverizing chamber, after entering pulverizing chamber by the material that feed inlet enters, can be protected The material situation for holding the two processing is in the level being closer to, and makes the state that a kind of dynamic equilibrium is maintained in pulverizing chamber.

The material baffle structure 23 for destroying circulation layer, material baffle structure 23 and the inner wall for crushing body 2 are equipped at the top of pulverizing chamber It is fixedly connected, material baffle structure 23 is along the first grinding rotor 21a or the second grinding rotor 21b axial directional distribution, and material baffle structure 23 in the tangential direction that the hammer leaf of the first grinding rotor 21a or the second grinding rotor 21b rotates；23 top of material baffle structure Width is greater than the width of its underpart, and it can be inverted triangle that the cross-sectional shape of material baffle structure 23, which is not limited to shape shown in figure, The rule such as shape, semicircle or irregular shape.

At this point, the material of larger particles high-speed motion in pulverizing chamber, to form circulation layer, circulation layer is located at hammer leaf week Outward.The position of material baffle structure 23 is in the first grinding rotor 21a and the hammer leaf of the second grinding rotor 21b is rotated to highest In the tangential direction of point.Herein it should be noted that the extreme lower position of material baffle structure 23 is lower than the first grinding rotor 21a or the The hammer leaf of two grinding rotor 21b is formed by the highest point of locus circle, and material baffle structure 23 will not mutually be hit with hammer leaf.When compared with Bulky grain will bump against when moving at the top of pulverizing chamber with material baffle structure 23, and the size and Orientation of larger particles speed becomes Change, larger particles will be crushed through grinding rotor together with smaller particle at this time, ensure the powder of pulverizer so on circulate Broken efficiency gets a promotion.

Further, material baffle structure 23 is symmetrical about the central axes of pulverizing chamber, and the outer wall of material baffle structure 23 is equipped with along it The detent projection portion of length direction distribution.The detent projection portion of the outer wall setting of material baffle structure 23 can change circulation to a greater degree The velocity magnitude of larger particles and direction in layer, are convenient for subsequent crushed work.

Further, the first sieve 3a and the second powder with the first grinding rotor 21a cooperation are further respectively had in pulverizing chamber Second sieve 3b, the first sieve 3a and the second sieve 3b of broken rotor 21b cooperation is arc sieve, the first sieve 3a and second The junction of sieve 3b is located at the first grinding rotor 21a between the first grinding rotor 21a and the second grinding rotor 21b And second the upper surface of the first sieve 3a between grinding rotor 21b and the second sieve 3b be all provided with and be equipped with the first tooth plate 25.When Material movement to pulverizing chamber bottom and when moving upwards, the larger particles in circulation layer collide with the first tooth plate 25, compared with Larger change occurs for bulky grain speed and size, carries out collision grinding into grinding rotor.

Further, crush and be additionally provided with the second tooth plate 27 on the inner wall of body 2, the second tooth plate 27 be located at the first sieve 3a, On the inner wall of the crushing body 2 of the top of second sieve 3b.When grinding rotor is rotated towards the inner wall direction of pulverizing chamber, circulation layer In larger particles collide with the second tooth plate 27, larger change occurs for larger particles speed and size, into grinding rotor Collision grinding is carried out, the crush efficiency of material is improved.

Further, the pulverizing chamber for crushing body 2 is drops.Can effectively it be changed using drops pulverizing chamber material bed Distribution destroys the circulation layer of material.Specifically, material enters after pulverizing chamber under the action of grinding rotor, first Circle, it is then for linear motion, generate refraction after, acceleration is reduced suddenly, generate backward acceleration after, and with hammer Piece bumps against, and continues to circle.So on circulate, then cooperate material baffle structure 23 and each tooth plate, thus significantly more efficient Destroy the circulation layer of material, and be not in it is big outside, small well-bedded mixing circulation inside, so that material is begun in pulverizing chamber It is in admixture eventually, greatly improves crush efficiency.

The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, the utility model Scope of patent protection be subject to claims, it is equivalent made by all specifications and accompanying drawing content with the utility model Structure change similarly should be included in the protection scope of the utility model.
