Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in figures 1-3, the special grinding machine for the alumina ceramic material comprises a shell 1 and is characterized in that an upper grinding disc 9 is arranged in the shell 1 in a sliding mode, a through groove 3 is formed in the upper grinding disc 9, a sliding block 4 is connected in the through groove 3 in a sliding mode, a sliding groove 17 is formed in the sliding block 4, a sliding rod 6 is connected in the sliding groove 17 in a sliding mode, one end of the sliding rod 6 extends out of the shell 1 and is rotatably connected with a swing rod 7 in a linked mode, when the swing rod 7 rotates, the sliding rod 6 slides along the sliding groove under the action force of the swing rod 7 to drive the sliding block 4 to slide in the through groove 3, the sliding block 4 exerts upward or downward force on the upper grinding disc 9 to realize that the upper grinding disc 9 moves up and down in the shell 1, a lower grinding disc 10 positioned below the upper grinding disc 9 is rotatably arranged in the shell 1, a plurality of material leaking holes 11 are formed, the bottom of the lower grinding disc 10 is fixedly connected with a main shaft 18, the main shaft 18 rotates to drive the lower grinding disc 10 to rotate together, under the combined action of the impact force of the upper grinding disc 9 and the friction force between the two grinding discs, the agglomerated materials are crushed and then ground into powder, a feed inlet positioned above the lower grinding disc 10 is formed in the shell 1, and a discharge outlet is formed in the bottom of the shell 1. The material falls onto the lower grinding disc 10 from the feeding hole, and is extruded and ground by the upper grinding disc 9 and the lower grinding disc 10, and the powder meeting the particle size requirement flows to the bottom of the shell 1 through the material leakage hole 11 and then flows out from the discharging hole.

The lower surface of the upper grinding disc 9 is of a convex arc surface structure with a protruding middle part, the upper surface of the lower grinding disc 10 is of a concave arc surface structure with a recessed middle part, and when the two grinding discs are closest to each other, the gap between the two grinding discs is smaller than the gap around the two grinding discs. When the material enters the shell 1, the material falls on the edge of the lower grinding disc 10 and gradually flows towards the concave part in the middle of the lower grinding disc 10 under the actions of extrusion of the upper grinding disc 9 and the gravity of the material, when the upper grinding disc and the lower grinding disc 10 are combined, the gap between the two grinding discs is gradually reduced from outside to inside, and the particle size of the material is gradually reduced in the grinding process.

The feed inlet department fixed link has the feeder hopper 8 that is located the casing 1 outside, and the discharge outlet department fixed link has the row's of being located the casing 1 outside to manage 13. All be located feeder hopper 8 before the material gets into casing 1, arrange material pipe 13 and play the effect for material transport, direction, powder departure and air pollution when avoiding the material output.

Still be equipped with the spring 5 of a plurality of equipartitions in the spout 17, the upper end and the slider 4 bottom fixed connection of spring 5, the lower extreme and the top fixed connection of last mill 9 of spring 5, be equipped with the anticollision piece 2 that is fixed in the casing top in the casing. The anti-collision block 2 prevents the upper grinding disc 9 from colliding with the shell when rising to the highest position; when the upper grinding disc 9 descends to the lowest position, the abrasion degree of the lower grinding disc 10 is increased due to the fact that the force exerted on the upper grinding disc 9 by the sliding rod 6 is too large, and the impact force of the upper grinding disc 9 on the lower grinding disc 10 is effectively relieved by the spring 5 between the sliding block 4 and the lower grinding disc 10.

The swing rod 7 is connected with a motor through a coupling, and the axis of the motor shaft and the axis of the slide rod 6 are not collinear. The motor drives the swing rod 7 to swing slowly, and the swing rod 7 drives the upper millstone 9 to move, so that the rotary motion is changed into linear reciprocating motion.

The lower end of the main shaft 18 extends out of the shell 1 and is connected with a motor through a belt mechanism 12. The motor drives the main shaft 18 to rotate after being decelerated by the belt mechanism 12, and the influence of centrifugal force on the flow direction of the materials is reduced.

The shell 1 is provided with an observation window 16. The working conditions inside the housing 1 are known to the operator through the observation window 16.

The lower part of the shell 1 is fixedly connected with a tripod base 14, and a damping spring 15 is arranged in a column base of the tripod base 14. The upper grinding disc 9 and the lower grinding disc 10 can generate vibration during grinding, and the three-foot base 14 supports the whole shell 1 and has a good damping effect.

The utility model discloses when using, add material and water simultaneously, reciprocal linear motion is done to the runner stone 9 in casing 1, lower mill 10 is rotary motion at a slow speed, the extrusion is executed to the material to two mill cooperations, cut, scrape shell and broken mixing power, the material is by the excircle of mill to the in-process granularity that centre of a circle direction removed diminishes, the material that the particle diameter meets the requirements is finally discharged casing 1 through leaking material hole 11, the material that does not reach the particle diameter requirement continues to be ground until meeting the standard and passing through leaking material hole 11.

The above-mentioned embodiments are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design concept of the present invention should be included in the protection scope defined by the claims of the present invention.
