It is noted that the term "comprising" in the description and claims of the present application is intended to cover a non-exclusive inclusion, e.g. a method comprising a list of steps is not necessarily limited to those steps explicitly listed, but may include other steps not explicitly listed or inherent to such methods. The embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail with reference to examples.

Examples

With reference to fig. 1-4, the present embodiment provides a baked brick raw material extrusion reducing mechanism, including shelves 1, crushing tank 2 and crushing roller 3, the bottom opening of crushing tank 2 forms the big bottom opening of upper portion opening and little tubular cavity structure, crushing roller 3 stretches into crushing tank 2 by the bottom opening of crushing tank 2, the clearance between crushing roller 3 and crushing tank 2 diminishes gradually from top to bottom, inner insection 21 is provided on the inner wall surface of crushing tank 2, outer insection 31 is provided on the outer surface of crushing roller 3. The during operation, motor 5 drives crushing roller 3 and rotates, and the material falls into the clearance between crushing roller 3 and the broken groove 2 after getting into broken groove 2, makes circular motion around crushing roller 3 under the drive of crushing roller 3, collides with interior insection 21 and external insection 31 in the motion process, receives the extrusion of crushing roller 3 with broken groove 2 simultaneously, and is cracked for the tiny particle material rapidly, by last cracked degree increase down, and final broken suitable particle diameter is discharged by the clearance of crushing roller 3 with broken groove 2 bottommost.

The scheme of extrusion fragmentation is passed through to this scheme, makes cubic material cracked, relies on 3 high rotations of crushing roller and the tangential collision of material and the extrusion of crushing roller 3 and broken groove 2 to make the material cracked. Compared with the existing powerful crushing scheme, the energy consumption is greatly reduced, and meanwhile, the particle size of crushed materials can be controlled by adjusting the size of the gap between the crushing roller 3 and the crushing groove 2, so that the materials are crushed to the designed size at one time.

The outer insections 31 and the inner insections 21 are oblique insections, the outer insections 31 incline clockwise from top to bottom, the inner insections 21 incline counterclockwise from top to bottom, and the crushing roller 3 rotates counterclockwise during operation. By this arrangement, in operation, the material is pressed and pushed by the crushing roller 3, and the force of the outer insection 31 is divided into a horizontal friction force and a downward pressure force in the tangential direction of the crushing roller 3, and the force of the inner insection 21 on the material is also divided into a horizontal friction force and a downward pressure force in the tangential direction of the inner surface of the crushing tank 2. The combined action effect is that a downward resultant force to the materials is formed, so that the materials are subjected to a larger extrusion force when moving downwards, and are broken and crushed quickly.

The tooth form of the external insection 31 is inclined in a parabola shape, and the inclination degree is gradually reduced from top to bottom; the tooth form of the inner insection 21 is also inclined in a parabola shape, and the inclination degree is gradually reduced from top to bottom. Because the materials are distributed in the gap between the crushing roller 3 and the crushing groove 2, the lower part is dense, and the upper part is loose, the inclination degree of the upper parts of the external insections 31 and the internal insections 21 is increased, so that the materials are prevented from jumping and leaking out of the crushing groove 2 in the processing process, and meanwhile, the materials are rapidly broken by applying larger downward pressure; but in the lower part in the clearance of crushing roller 3 and broken groove 2, the material distributes compactly, needs to make the material receive abundant grinding and smashes just can make it cracked to qualified size, designs too big can cause the material to block up in the bottom with the inclination degree of insection, has increased the load of equipment, is unfavorable for broken normal clear. The gradual change of the inclination degree of the external insections 31 and the internal insections 21 just meets the crushing requirement of the material in each stage of crushing, the crushing effect is excellent, and the energy consumption is greatly reduced. A fine grinding section 23 is arranged at the bottom of the crushing groove 2, a grinding section 33 is arranged at the bottom of the crushing roller 3, the inner wall of the fine grinding section 23 and the outer wall of the grinding section 33 are both vertically arranged, fine grinding insections 22 are arranged on the surface of the fine grinding section 23, the inclination direction of the fine grinding insections 22 is the same as that of the internal insections 21, and the fine grinding insections 22 are linear insections, and the inclination degree of the fine grinding insections is greater than that of the lowest end of the internal insections 2; the surface of the grinding section 33 is provided with grinding insections 32, the grinding insections 32 are linear insections, the inclination direction of the linear insections is the same as that of the external insections 31, and the inclination degree of the grinding insections 32 is greater than that of the lowest end of the internal insections 21; grinding segment 33 is higher than slender segment 23. Due to high requirements on the quality of products, in order to ensure the stable quality of the crushed materials, the grinding section 33 and the fine grinding section 23 are added to further cause collision and dispersion among the materials, so that the particle size of the obtained crushed materials is more uniform, the inclination degree of the fine grinding insection 22 and the polishing insection 32 is increased, the materials are forcibly sucked into the fine grinding section 23, the discharging process of equipment is enhanced, and the processing efficiency of the device is improved; in addition, the height of the grinding section 33 is larger than that of the fine grinding section 23, so that the material is descended at a higher speed on the surface of the grinding section 33 before entering the surface of the fine grinding section 23, the material rolls at the surface, fine particles sink, large particles float upwards, screening is formed at the surface, the fine particles enter the fine grinding section 23 to be discharged as soon as possible, and meanwhile, the retention time of the material with larger particles in the equipment is prolonged, so that the material is further crushed. This allows the overall reduction of the energy consumption of the plant and at the same time increases its crushing efficiency.

The crushing roller 3 is in the shape of a circular truncated cone. The round table-shaped crushing roller 3 can provide a larger space for storing materials, and the processing capacity of the device is increased. Combine the shape in broken groove 2 simultaneously, the clearance in broken roller 3 and broken groove 2 is the ascending loudspeaker form of opening, can give the abundant escape space of material like this, and when the extrusion force that anti material received was too big, the space of dodging upwards avoids taking place and pressure is too big to cause the dead condition of equipment card to take place. The motor 5 connected below the crushing roller 3 is arranged on a beam 11 of the frame 1, a bracket 6 is also arranged on the beam 11 and used for supporting the crushing roller 3, and an axial bearing 4 is arranged between the bracket 6 and the bottom of the crushing roller 3. The crushing roller 3 is provided with a hollow structure inside. Because the crushing power of this device is not from the powerful inertia of crushing roller 3 itself, through setting up crushing roller 3 into hollow structure, can reduce the cost greatly, reduce the energy consumption of device simultaneously.
