The grinding rollers 92 are fixed on the corresponding mounting rods 52 through a frame 93.

[0029] In this embodiment, the two ends of the guide bucket 91 are fixedly connected to the corresponding outer wall of the cylinder 2 and the inner wall of the barrel body 1 respectively. A circle of collecting troughs 10 is arranged between the cylinder 2 and the side wall of the barrel body 1 below the guide bucket 91. Vertical pipes 11 are evenly arranged at the bottom of the collecting trough 10, and a dust collecting bag II12 is arranged on the outer sleeve of the vertical pipe 11.

[0030] The gas circulation mechanism 8 includes a spiral channel 81 arranged in the support plate 41, and the screw holes and through holes are staggered with the spiral channel 81. The upper and lower end surfaces of the support plate 41 are evenly provided with air outlet holes 82 connected with the spiral channel 81.

A vertical pipe 86 is arranged on the outside of the cylinder 2, and the bottom end of the vertical pipe 86 is bent and connected to the cylinder 2 below the support plate 41. A purge pipe 87 with a circle of sleeves on the cylinder 2 is arranged on the top of the vertical pipe 85. The purge pipe 87 is located below the guide bucket 91, and an air outlet nozzle is arranged on one side of the top of the purge pipe 87 tilted upward.

[0031] In this embodiment, dust suction holes are evenly arranged on the side wall of the dust suction pipe 71. The dust suction pipe 71 is fixed on the top of the barrel body 1. The dust suction pipe 71 is composed of a main pipe and multiple groups of branch pipes located on both sides of the main pipe. The ends of the main pipe and the branch pipes extend to the outside of the top of the cylinder 2.

[0032] like Figure 1 As shown, a feed pipe 13 is provided on the side wall of the barrel body 1 , and the feed pipe 13 is connected to the cylinder 2 below the guide bucket 91 .

[0033] The adjusting mechanism 6 includes a magnetic plate 61 arranged between the mounting rod 52 and the dust suction pipe 71, and the magnetic plate 61 is made of electromagnet material. The magnetic plate 61 is fixed to the inner top wall of the barrel body 1 through a mounting frame. The mounting rod 52 is provided with a mounting hole 62 for the vertical rod 53 to pass through, and a metal plate 63 is provided at the top of the vertical rod 53. A protrusion 64 is provided on the vertical rod 53 below the mounting rod 52, and a spring 65 is arranged on the outer sleeve of the vertical rod 53 between the protrusion 64 and the mounting rod 52.

[0034] The method of using the present invention is as follows: materials are added into the cylinder 2 through the feed pipe 13, wherein the materials in different areas of the cylinder 2 are heated and dried through the heating tube 31 to facilitate the subsequent screening work, and at the same time, the motor I43 drives the screw 42 to rotate in the screw hole on the support plate 41, thereby driving the support plate 41 and the materials above it to slowly move upward, and at this time, the through hole on the support plate 41 moves upward on the heating tube 31, and when the material is close to the top opening of the cylinder 2, the motor II51 drives the mounting rod 52 to drive the vertical rod 53 to rotate, thereby stirring the material located at the top opening of the cylinder 2, thereby breaking up the heated material so that the broken up material can be diffused in the barrel body 1;

[0035] At this time, the exhaust fan 75 draws the dust-like materials diffused on the top of the barrel body 1 into the dust bag I74 through the connecting pipe 72, the dust suction pipe 71 and the dust suction hole for filtration and collection, and the materials that are not broken up fall on the guide bucket 91 under the influence of gravity. At this time, the rotating mounting rod 52 drives the grinding roller 92 to roll on the top surface of the guide bucket 91 through the mounting frame 93, thereby repeatedly grinding the materials on the top, so that the qualified materials after grinding are sieved by the aperture of the side wall of the guide bucket 91 and fall into the collecting trough 10, and finally enter the dust bag II12 through the vertical pipe 11 for collection;

[0036] In the above process, in order to adjust the length of the rod body of the vertical rod 53 extending into the cylinder 2 so that it will not affect the support plate 41 to push out the material in the cylinder 2, and at the same time, the material in the cylinder 2 can be stirred and dispersed over a large area to the maximum extent, the current of the magnetic suction plate 61 made of the electromagnet material can be controlled at this time. When the magnetic suction force increases, it generates a magnetic suction force to exert an upward pulling force on the metal plate 63. At the same time, the upward moving metal plate 63 drives the vertical rod 53 to move upward in the mounting hole 62, and also drives the protrusion 64 to move upward and compress the spring 65. When the magnetic suction force decreases, the spring 65 stretches and pushes the protrusion 64 to drive the vertical rod 53 downward, thereby adjusting the rod body length of the bottom end of the vertical rod 53 inserted into the top of the cylinder 2 to meet the production requirements. At the same time, when the magnetic suction force generated by the magnetic suction plate 61 does not pull the metal plate 63 to contact it after moving up, the two will not be magnetically connected, so that the magnetic suction plate 61 will not affect The mounting rod 52 drives the vertical rod 53 to rotate, and at the same time, the magnetic attraction force generated by the magnetic plate 61 can play a magnetic attraction and impurity removal role for the metal debris that may exist in the material, and it can also play a role in shielding and bending the material after being scattered by the scattering mechanism 5, so as to prevent the large particles of scattered and splashed materials from directly splashing to the dust suction pipe 71 and being sucked out by it. At this time, under the influence of the magnetic plate 61, the material is splashed to the outside of the cylinder 2, and the large volume of material will fall on the guide bucket 91 under the influence of gravity, and the problem of bending upward through the edge of the magnetic plate 61 to contact the dust suction pipe 71 and finally being extracted by the dust suction pipe 71 will not occur. In this process, the dust particles are light in weight and float on the top of the barrel body 1. At this time, under the influence of the suction force generated by the exhaust fan 75, the connecting pipe 72 and the dust suction pipe 71, the dust particles that meet the standards and diffuse in the top of the barrel body 1 will be bent upward at the edge of the magnetic plate 61 and contact the dust suction pipe 71, and finally be extracted by the dust suction pipe 71.

[0037] When in use, the exhaust fan 75 draws the powdered material in the barrel body 1 into the dust bag 174 through the connecting pipe 72 and the dust suction pipe 71 for collection. At this time, the filtered gas enters the corrugated hose 84 and the spiral channel 81 through the recovery pipe 85 and is sprayed toward the upper and lower sides of the support plate 41 through a plurality of air outlets 82. When the support plate 41 drives the material in the cylinder 2 to move upward, the airflow sprayed from the air outlet 82 on the upper side of the support plate 41 can pneumatically stir the slowly moving material above it to initially disperse it. At the same time, the pneumatically stirred material can fully contact the heating tube to improve its heating and drying efficiency, and another part of the gas flows into the cylinder 2 below the support plate 41 at this time, and the heating tube 31 can heat this part of the gas. The heated gas can enter the purge pipe 87 through the vertical pipe 86 and be ejected by a number of air nozzles, and then surge up from the apertures on the side wall of the guide bucket 91. At this time, the hot air flow has a blowing effect on the apertures on the side wall of the guide bucket 91 to prevent it from being blocked, and at the same time, it can disperse and heat the materials obtained by grinding and sifting, and heat and dry the materials above the guide bucket 91, thereby facilitating the grinding work of the grinding roller 92, and the hot air flow flowing to the top of the guide bucket 91 can also play a role of blowing upwards on the materials dispersed by the scattering mechanism 5, so that the fine materials dispersed by it can be fully diffused in the top of the barrel body 1 and extracted by the dust collecting mechanism 7.

[0038] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
