Technical Field

The utility model relates to the technical field of rolling and crushing block materials, in particular to a rolling and crushing device for block materials.

Background Art

As shown in FIG. 1 to FIG. 6 , based on the above embodiment, this embodiment further provides the following contents:

The working principle and use process of this utility model:

In use:

First, the block material to be crushed is put into the crushing box 4 from the feeding hole 6 end of the U-shaped platform 7. At this time, the block material is made to fall between the first squeezing roller 55 and the second squeezing roller 56 through the first inclined plate 57 and the second inclined plate 58. At this time, the squeezing motor 51 is started. When the squeezing motor 51 works, it will drive the worm 52 to rotate. When the worm 52 rotates, it will drive the first worm gear 53 and the second worm gear 54 to rotate in opposite directions. When the first worm gear 53 and the second worm gear 54 rotate in opposite directions, the block material begins to be squeezed and deformed, and it is made into a smaller powder block. When the large block material is squeezed into When the powder is in the form of a small lump, the small lump of powder will fall from the crushing box 4 into the crushing barrel 1, and the powder will be crushed into small pieces and located between the conical barrel 37 and the grinding cone 36 (the surface of the grinding cone 36 and the inner surface of the conical barrel 37 are both rough surfaces). At this time, the crushing motor 31 is started. When the crushing motor 31 is working, it will drive the crushing shaft 32 to rotate, and when the crushing shaft 32 rotates, it will drive the grinding cone 36 to rotate. When the grinding cone 36 rotates, it starts to cooperate with the conical barrel 37 to perform secondary friction crushing on the material that was crushed for the first time. Because the surface of the grinding cone 36 and the inner surface of the conical barrel 37 are The gap is larger at the top and smaller at the bottom. Therefore, when the material that has been squeezed and crushed for the first time undergoes secondary friction crushing, the gap will become smaller. At this time, the secondary ground material will fall from the lower part of the conical cylinder 37 to the filter screen 38. During the falling process, the hot air blower 91 is started. The hot air blower 91 will heat the outside air through the cooperation of the heating rod and the blower, and discharge it into the annular coil 92 through the air outlet pipe 93. Finally, it will be sprayed out through the ventilation pipe 95 on the annular coil 92 to start heating and drying the material on the filter screen 38 to prevent residual moisture in the material, which will cause the material to agglomerate. When the material When the material falls on the filter screen 38, the crushing motor 31 drives the crushing shaft 32 to rotate, and at the same time, drives the triangular rod 34 and the cutting knife 35 to rotate. When the triangular rod 34 rotates, the residual material on the filter screen 38 can be scraped up from the top of the filter screen 38 to make it float, and then it is cut and separated by the rapidly rotating cutting knife 35 until the material can fall through the holes in the filter screen 38, and the fallen material will fall to the bottom of the inner cavity of the crushing cylinder 1. At this time, the crushed and compliant material can be discharged from the discharge pipe 2 at the bottom of the crushing cylinder 1 through the cleaning plate 33, and the crushing and crushing of the material can be completed.

When large pieces of material are squeezed and crushed, the dust generated by the squeezing and crushing will float upward. At this time, the dust suction motor 85 is started. When the dust suction motor 85 is working, it will drive the dust suction fan blades 86 to rotate. At this time, the dust in the crushing box 4 will enter the suction box 81 from the dust suction pipe 83, and finally enter the L-shaped wind collecting bucket 82. At this time, the dust will be blocked by the dust blocking mesh plate 87, and the air will be discharged from the exhaust hole 84. When exhausting the air, some hot air will be sucked into the air inlet pipe 93 for recycling, and some larger dust will be blocked by the dust blocking mesh plate 87 and will fall into the ash receiving box 89 and be collected, which is convenient for subsequent centralized processing.
