The working principle of this programme is: porous brick is produced according to above-mentioned steps, it, will when needing using crushing mixer Prepared various materials are placed in hopper, then start motor, and motor drives worm screw rotation, and worm screw drive broken cylinder and Worm gear rotates simultaneously.When the bin gate on crushable layer turns to the lower section of discharge port, since the gravity of material is larger, in object Under material effect, to opening inside crushable layer, the material on hopper is entered in crushable layer bin gate by bin gate.As broken cylinder turns Dynamic, breaker roll constantly moves in crushable layer, and breaker roll is impinged upon on broken cylinder, impinged upon on material, broken material.It is broken to close The material of lattice can be transferred in feeding layer by separating opening, and the biggish material continuation of partial size is broken in crushable layer.It send Material in the bed of material enters in sand cylinder subsequently into feed pipe eventually by feed pipe along separating plate slide downward.Broken During broken cylinder rotation, worm gear drives rotation axis to rotate simultaneously, and rotation axis drives switch block movement.Switch block drive push away column to Lower movement drives briquetting downward together during pushing away column movement.When briquetting, which is moved to, to be contacted with material, briquetting is pressed in material On, column is pushed away at this time and continues to move downward, and spin is moved downward also along spiral groove, and under the action of pushing away column, briquetting is squeezed It is rotated centered on cavity while pressing material, briquetting grinds material, and sieve can be passed through by grinding qualified material Sieve pore on plate enters the bottom of sand cylinder.
The beneficial effect of this programme is:
1, motor is crushed cylinder rotation by worm drive, during the rotation of broken cylinder, utilizes the impact force of breaker roll Material is crushed, qualified material is crushed and feeding layer is entered by separating opening, underproof material continues to be crushed；And it is broken During cylinder rotation, the cooperation between broken cylinder and hopper is also able to achieve self-feeding, and being not required to worker one after another will be to broken Broken material pours into broken cylinder, and the working strength of worker is effectively reduced, and improves processing efficiency.
2, when being crushed cylinder rotation, material constantly moves in broken cylinder, prepares the various objects of porous brick in this process Material is sufficiently mixed, and after the completion of being crushed, each material is also uniformly mixed, and is not required to the step of additionally being mixed, and improves production efficiency.
3, unilateral gate is set, and unilateral gate can only be opened to feeding layer side, avoid being crushed during broken cylinder rotates Qualified material is again introduced into crushable layer by separating opening.
4, separating plate is obliquely installed, and the material into feeding layer slides under self gravitation effect along separating plate, then Into feed pipe, finally enter sand cylinder, be not required to it is artificial material is shifted, effectively improve processing efficiency.
5, it after material enters sand cylinder, can also be rotated centered on cavity while briquetting squeezes plank, Material both by the extruding force of briquetting application or the torsion applied by briquetting, enabled material to be fully ground, grinding effect It is good.
6, the power resources of fragmentation cell and grinding unit are all from the same motor, and a motor is arranged while driving brokenly Broken unit and grinding unit work, facilitate the structure for simplifying device.
Further, shock roller is fixed in crushable layer.When roller, breaker roll and shock roller collision are hit in setting, it can generate strong Big impact force, is conducive to broken material.
Further, the surface of breaker roll is equipped with multiple convex thorns.The setting of convex thorn helps to make stock dispersion, makes crushing effect More preferably.
Further, groove is provided in breaker roll, separating plate is fastened on groove, and bullet is connected between groove and separating plate Spring.During broken cylinder rotation, breaker roll can move in crushable layer, can apply to separating plate when breaker roll is contacted with separating plate Add active force, spring is compressed, and separating plate shakes, and the material on separating plate is made to enter feeding more easily by separating opening Layer, and effectively material can be avoided to be stuck on separating opening.
