Screening mechanisms 8 are provided on the top of the box body 1 on both sides of the feed box 7;

[0027] The screening mechanism 8 includes a vertical pipe 81 connected to the box body 1, the top of the vertical pipe 81 is sealed, a rotating shaft 82 connected to the top motor 83 is provided in the vertical pipe 81, a filter screen 85 for the rotating shaft 82 to pass through is provided in the vertical pipe 81, fan blades 84 are provided on the rotating shaft 82 on the upper and lower sides of the filter screen 85, a mounting bracket 86 for fixing the magnetic rod 87 is provided on the rotating shaft 82 above the filter screen 85, a connecting port 88 connected to the feed box 7 is provided on one side wall of the vertical pipe 81 below the filter screen 85, and a guide plate 89 is hinged on the other side of the vertical pipe 81 through a hinge. A U-shaped notch 810 corresponding to the rotating shaft 82 is provided at the end, and a rubber strip 816 is bonded to one end surface of the guide plate 89 on both sides of the U-shaped notch 810, and one end of the rubber strip 816 extends to the opening of the U-shaped notch 810. An electric push rod I811 connected to the bottom of the guide plate 89 through a movable seat is provided on the outside of the vertical pipe 81, and a filter box 812 is also provided on the outside of the vertical pipe 81. A discharge pipe 813 connected to the top of the vertical pipe 81 is provided in the filter box 812, and a dust bag 814 is provided on the outer cover of the discharge pipe 813 in the filter box 812. The filter box 812 is connected to the inside of the net cylinder 5 through a pipe 815.

[0028] like Figure 2 As shown, a guide hopper 9 extending to the top between the two sets of grinding rollers 2 is provided at the bottom of the feed box 7, and the connecting port 88 is located above the guide hopper 9. A rectangular edge 10 is provided in the feed box 7 to seal the connecting port 88, and the edge 10 is driven by an electric push rod II11.

[0029] like Figure 6As shown, the guide plate 89 is located between the lower fan blade 84 and the filter screen 85. The top of the guide plate 89 is hinged and fixed to the inner wall of the vertical tube 81 by a hinge. The electric push rod I811 drives the guide plate 89 to rotate with the hinge as the center. After rotation, the guide plate 89 is tilted and its bottom end is against the inner wall of the vertical tube 81 below the corresponding connecting port 88. The rotated guide plate 89 drives the U-shaped notch 88 to buckle on the corresponding rotating shaft 82.

[0030] Preferably, a circular tube 12 is provided at one end of the toothed disc 4 and passes through the side wall of the box body 1. One end of the circular tube 12 is connected to the internal opening of the mesh cylinder 5. The internal openings of one group of circular tubes 12 are sealed, and a three-way pipe 13 is provided in the opening of the other group of circular tubes 12. The three-way pipe 13 is connected to the corresponding filter box 812 through the pipe 815.

[0031] In this embodiment, the diameter of the circle formed by the plurality of magnetic plates 6 matches the diameter of the toothed disc 4. The toothed disc 4 and the bottom end of the lowest magnetic plate 6 are both attached to the inner bottom wall of the box body 1.

[0032] In this embodiment, a plastic tube is provided over the magnetic rod 87, and a bump is provided at the bottom of the magnetic rod 87. When metal debris is attracted to the magnetic rod 87 and the machine is stopped, the plastic tube can be slid to scrape the metal debris off the magnetic rod 87 to separate the two, thereby facilitating the recovery of the metal debris.

[0033] The working principle of the present invention is as follows: the raw material is introduced into the feed box 7 through the feed pipe 14, and then introduced into the space between two sets of rotating grinding rollers 2 through the guide hopper 9, wherein the grinding rollers 2 grind and crush the raw material through the strip-shaped gear teeth 3, and when the grinding rollers 2 rotate, the gear disc 4 is driven to rotate through the gear teeth 3 on its side wall, and the gear disc 4 drives the magnetic plate 6 to rotate through the mesh cylinder 5, as shown in FIG. Figure 2 As shown, the raw materials dropped after being ground by the grinding roller 2 will fall between the two adjacent sets of magnetic plates 6 above, or fall on the bottom of the box 1 near the mesh cylinder 5 and the magnetic plates 6. During this process, the rotating magnetic plates 6 will lift the ground powder so that it spreads on the bottom of the box 1. At this time, when the magnetic plates 6 come into contact with the powder and lift it up, they will magnetically remove the metal impurities in the powder, so that the powder and the metal impurities are separated.

[0034] At the same time, the motor 83 drives the fan blades 84 to rotate through the rotating shaft 82, thereby creating a negative pressure in the vertical pipe 81 to absorb the powder lifted in the box body 1, so that the powder enters the vertical pipe 81 under the influence of suction, and is then filtered through the filter screen 85. At this time, the qualified powder flows to the top of the filter screen 85, wherein the rotating shaft 82 drives the magnetic rod 87 to rotate through the mounting bracket 86 when rotating, so as to play a magnetic separation role on the powder flowing to the top of the vertical pipe 81, and finally the qualified powder with metal impurities removed enters the removal through the discharge pipe 813. The dust is filtered and collected in the dust bag 814. At this time, the gas flows out through the dust bag 814, then enters the mesh drum 5 through the pipe 815, the tee pipe 13, and the round pipe 12, and flows out through the apertures on the side wall of the mesh drum 5, thereby blowing the powder dropped after being ground by the grinding roller 2, so that the powder is fully lifted and the screening mechanism 8 can extract the powder. At the same time, the powder on the magnetic plate 6 is blown to separate it from the heavier metal impurities, so that the metal impurities can come into contact with the magnetic plate 6 and be adsorbed on its end surface, thereby achieving the purpose of fully removing the metal impurities.

[0035] In the above process, the suction force in the vertical pipe 81 is strengthened by rotating multiple sets of fan blades 84 to prevent a large amount of powder from being deposited below the filter 85 after filtering a large volume of powder, thereby affecting the flow of gas through its aperture. When there is a lot of filtered powder below the filter 85, the electric push rod II11 drives the edge 10 to move upward to open the connecting port 88. At the same time, the electric push rod I811 drives the guide plate 89 to rotate with the hinge as the center of the circle, wherein the U-shaped notch 810 on the rotating guide plate 89 will be buckled on the rotating shaft 82. When the U-shaped notch 810 is buckled on the rotating shaft, the rubber strip 816 will be squeezed to deform it, thereby facilitating the buckling of the U-shaped notch 810 on the rotating shaft 82. Figure 6 、 7 As shown, when the guide plate 89 divides the vertical tube 81 into two parts, the bottom end of the guide plate 89 is located below the communication port 88 and abuts against the side wall of the vertical tube 81. At the same time, the deformed rubber strip 816 stretches and cooperates with the rotating shaft 82 to seal the opening of the U-shaped notch 810. When the motor 83 stops working, the upward suction and upward thrust generated by the rotation of the fan blades 84 driven by the rotating shaft 82 are lost. The large volume of powder filtered by the bottom of the filter screen 85 will fall onto the guide plate 89 and the rubber strip under the influence of gravity. The powder passes through the rubber strip 816 and then flows along the inclined surfaces of the two into the connecting port 88, and finally enters the feed box 7 and enters the grinding roller 2 in the box body 1 through the guide hopper 9 for further grinding. Of course, in order to quickly separate the powder at the bottom of the filter screen 85, a vibration device can also be set on the filter screen 85 to shake it, thereby accelerating the shedding efficiency of the powder. Then the electric push rod II11 drives the edge 10 to move downward to seal the connecting port 88, and the electric push rod I811 drives the guide plate 89 to reset, and repeats the above steps.

[0036] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
