[0002] The existing Chinese patent, CN112354620A (a method for recycling and reusing metallurgical solid waste), crushes metallurgical solid waste by rotating and extruding a crushing unit. First, the material is easy to block the drop hole during the crushing process, resulting in the powder being unable to fall downward, affecting the recovery of metal particles.

[0039] An interception net 002 is provided in each collection tank 001 .

[0040] The collecting component includes a weak magnetic roller 301, a brush plate 302, a guide plate 303 and a power motor 305; two weak magnetic rollers 301 are rotatably connected in the mounting shell 2; a gap is arranged between the two weak magnetic rollers 301 and the inner left wall and the inner right wall of the mounting shell 2; two power motors 305 are bolted to the rear side of the mounting shell 2; the output shaft of each power motor 305 is fixedly connected to a weak magnetic roller 301; three equidistant guide plates 303 are arranged on the base 1; all the guide plates 303 are connected to the mounting shell 2; the mounting shell 2 is fixedly connected to two left-right symmetrical brush plates 302; each brush plate 302 is located below a weak magnetic roller 301, and the surface of the weak magnetic roller 301 is in contact with the bristles of the brush plate 302.

[0042] A plurality of circular rings 301 a are arranged on each weak magnetic roller 301 . The circular rings 301 a are made of iron. The circular rings 301 a on two weak magnetic rollers 301 are spaced apart from each other, and the outer surface of each circular ring 301 a is close to the surface of the corresponding weak magnetic roller 301 .

[0043] Two grinding blocks 101 a are arranged on the grinding roller 101 , and all the grinding blocks 101 a are plugged into the grinding roller 101 , and all the grinding blocks 101 a are bolted to the grinding roller 101 via connecting blocks.

[0044] All guide plates 303 are slidably connected to the mounting shell 2 , and a handle 304 is provided on the rear side of each guide plate 303 .

[0045] The working principle of the above embodiment is as follows:

[0046] During operation, the two power motors 305 are controlled to start. With the view from the front to the back as the reference, the output shaft of the right power motor 305 rotates counterclockwise, and the output shaft of the left power motor 305 rotates clockwise, so that the two weak magnetic rollers 301 rotate in opposite directions. The connector 107a is connected to the external air pump through a conduit, and the metallurgical solid waste is input into the crusher 3 through the external feeding equipment and crushed into fine pieces. The fine pieces fall downward and are guided to the space between the grinding roller 101 and the arc plate 106 through the guide mesh plate 102, while the powder produced by the crushing passes through the guide mesh plate 102 and falls downward to the guide plate 203, and is guided to the space between the two weak magnetic rollers 301 through the guide plate 203. Then the drive motor 105 is controlled to start. The output shaft of the driving motor 105 drives the fixed rod 107 and the grinding roller 101 to rotate counterclockwise, and the grinding block 101a on the grinding roller 101 cooperates with the arc plate 106 to grind the fine pieces into powder. As the grinding roller 101 rotates, the powder is collected in the collecting tank 001. When the collecting tank 001 is aligned with the top of the guide mesh plate 102, the external air pump connected to the connector 107a through the conduit is started, so that the air is input into the nozzle 104 through the fixed rod 107 and the air guide pipe 103. The air is ejected through the nozzle 104 to blow the powder in the collecting tank 001 and the fine pieces that have not been ground into powder onto the guide mesh plate 102. As the grinding roller 101 continues to rotate, the powder is Figure 4In the state shown, the external air pump connected to the connector 107a through the conduit is closed, and the fine pieces are blown onto the guide mesh 102, and then guided to the grinding roller 101 and the arc plate 106 for grinding again through the guide mesh 102, and the powder on the guide mesh 102 falls downward and is guided between the two weak magnetic rollers 301 through the guide plate 203, and the metal particles in the powder are adsorbed on the weak magnetic roller 301, and other impurity powders fall downward from the interval between the two weak magnetic rollers 301 onto the guide plate 1 303 in the middle, and are discharged through the guide plate 1 303 for unified collection. As the two weak magnetic rollers 301 rotate, the metal particles adsorbed on the two weak magnetic rollers 301 are brushed off by the brush plate 1 302 and fall onto the left and right guide plates 1 303, and the metal particles are discharged through the left and right guide plates 1 303 for unified collection.

[0047] According to the above working principle, we know that the present invention has the following effects:

[0048] After the metallurgical solid waste is crushed by the crusher 3, it is ground by the grinding roller 101 and the arc plate 106. The broken materials that are not ground into powder are guided to the grinding roller 101 and the arc plate 106 for grinding again through the guide mesh plate 102 to ensure the final powdering rate of the metallurgical solid waste and the recovery rate of metal particles in the metallurgical solid waste. The metal particles in the powder are adsorbed by the weak magnetic roller 301, and the impurities in the powder are collected in the guide plate 303 in the middle of the base 1 and discharged. The metal particles on the weak magnetic roller 301 are brushed off by the brush plate 302 to avoid the accumulation of adsorbed metal particles on the weak magnetic roller 301 affecting the adsorption effect, so as to ensure the recovery rate of metal particles under continuous working conditions, and the metal particles are discharged through the left and right guide plates 303, so that the metal particles and impurities are separated and collected.

[0049] On the basis of the above technical effects, the present invention also has the following advantages:

[0050] First, by setting an iron ring 301a on the weak magnetic roller 301, the area of ​​the weak magnetic roller 301 for adsorbing metal particles is indirectly increased to ensure the recovery rate of metal particles, and the ring 301a cooperates with the corresponding weak magnetic roller 301 to crush the fallen materials again to ensure the final powdering rate of metallurgical solid waste, thereby ensuring the recovery rate of metal particles;

[0051] Second, an interception net 002 is set in the collection tank 001 to prevent powder and debris from clogging the jet head 104;

[0052] Third, a grinding block 101a that is easy to disassemble is provided on the grinding roller 101, so that the grinding block 101a can be replaced regularly, and the arc plate 106 can be replaced regularly to ensure the grinding effect of the grinding roller 101;

[0053] Fourthly, all the guide plates 303 are arranged to be slidably connected with the mounting shell 2, and a handle 304 is arranged at the rear side of all the guide plates 303, so as to facilitate taking out the guide plates 303 and cleaning the residues after the work is finished.

[0054] Example 2

[0055] On the basis of Example 1, Figure 3 and Figure 7-9 As shown,

[0056] It also includes a sliding frame 201 and a brush plate 202; each guide mesh plate 102 is slidably connected to a sliding frame 201, and limiting balls 201b are arranged on both sides of the sliding connection between the sliding frame 201 and the guide mesh plate 102, and all limiting balls 201b are rotatably connected to the sliding frame 201; all limiting balls 201b are in contact with the guide mesh plate 102; each sliding frame 201 is connected to a brush plate 202 through a torsion spring shaft, and the torsion spring shaft is in a torsion state in its initial state; each brush plate 202 is fixedly connected to two top plates 004; each guide mesh plate 102 is fixedly connected to two blocks 003; each top plate 004 is in contact with a block 003 in its initial state; a gap is arranged between the bristles of each brush plate 202 and the corresponding guide mesh plate 102.

[0057] It also includes an electromagnetic plate 401; an electromagnetic plate 401 is respectively arranged on the inner left wall and the inner right wall of the mounting shell 2; the two electromagnetic plates 401 correspond to the two weak magnetic rollers 301 respectively, and a gap is arranged between each electromagnetic plate 401 and the corresponding weak magnetic roller 301, and the magnetic force of the electromagnetic plate 401 when it is turned on is greater than the magnetic force of the weak magnetic roller 301.

[0058] The front and rear of each sliding frame 201 are rotatably connected to two guide rollers 201 a , and all guide rollers 201 a are in contact with corresponding guide mesh plates 102 .

[0059] The working principle of the above embodiment is as follows:

[0060] In the process described in Example 1, when the air is ejected from the air jet head 104 to blow the powder in the collecting tank 001 onto the guide mesh plate 102:

[0061] When the air jet 104 sprays air to blow the powder in the collecting tank 001 onto the guide mesh plate 102, the torsion spring shaft at the connection between the brush plate 202 and the sliding frame 201 is in a twisted state, the brush plate 202 is in an inclined state, and there is a gap between the bristles of the brush plate 202 and the guide mesh plate 102. After the fine and broken pieces are blown onto the guide mesh plate 102, they are guided by the guide mesh plate 102 from under the bristles of the brush plate 202 through the re-guided grinding roller 101 and the arc plate 106 for grinding again. As the grinding roller 101 continues to rotate, the air jet 104 faces the sliding frame 201, and then blows the sliding frame 201, so that the sliding frame 201 slides obliquely upward in the guide mesh plate 102, and the limiting ball 201b moves in contact with the guide mesh plate 102, so that the limiting ball 201b rotates in the sliding frame 201. The sliding frame 201 drives the brush plate 202 to move, so that the top plate 004 is separated from the block 003, and the torsion spring shaft at the connection between the brush plate 202 and the sliding frame 201 releases the elastic force, thereby causing the brush plate 202 to rotate, so that the bristles of the brush plate 202 contact the guide mesh plate 102, and the brush plate 202 moves with the sliding frame 201, and the brush plate 202 cleans the residual powder on the guide mesh plate 102. After the air pump is turned off, the sliding frame 201 slides back and resets due to gravity, and the guide mesh plate 102 is cleaned again through the brush plate 202, and the top plate 004 is again against the corresponding block 003, so that the brush plate 202 rotates and the torsion spring shaft at the connection with the sliding frame 201 is twisted, so that a gap is generated between the bristles of the brush plate 202 and the surface of the guide mesh plate 102, and it returns to its initial state.

[0062] According to the above working principle, we know that the present invention has the following effects:

[0063] The air sprayed from the air jet head 104 is used to make the sliding frame 201 drive the brush plate 202 to move and automatically clean the guide mesh plate 102, so as to prevent the residual powder on the guide mesh plate 102 from clogging and affecting the normal falling of the powder.

[0064] On the basis of the above technical effects, the present invention also has the following advantages:

[0065] First, an electromagnetic plate 401 is respectively arranged on the inner left wall and the inner right wall of the installation shell 2, and the electromagnetic plate 401 is started at a fixed time to absorb the residual metal particles on the weak magnetic roller 301, so as to avoid the accumulation of metal particles on the weak magnetic roller 301 due to incomplete cleaning of the brush plate 302, which affects the adsorption effect. The magnetic force of the weak magnetic roller 301 is relatively weak, and there is a gap between the weak magnetic roller 301 and the electromagnetic plate 401. When the two electromagnetic plates 401 are closed, the metal particles adsorbed on the electromagnetic plate 401 will not be adsorbed by the weak magnetic roller 301 again, so that the metal particles adsorbed on the two electromagnetic plates 401 fall into the corresponding guide plate 303 for discharge and collection;

[0066] Second, guide rollers 201 a are provided at the front and rear of the sliding frame 201 , and the sliding frame 201 is supported by the guide rollers 201 a contacting with the guide mesh plate 102 , so as to ensure that the sliding frame 201 slides smoothly in the guide mesh plate 102 .

[0070] The working principle of this embodiment is as follows:

[0071] In the process of cleaning the residual powder on the guide mesh plate 102 by the brush plate 202 described in Example 2:

[0072] The powder dropped when the brush plate 202 cleans the guide screen 102 is collected by the collecting frame 501. When the sliding frame 201 drives the brush plate 202 to slide obliquely upward to the end of the stroke, the powder collected in the collecting frame 501 is opposite to the opening of the suction box 502 (before work, the connecting pipe 506 is connected to the external dust suction device 1 through the conduit, and the suction pipe rack 2 507 is connected to the external dust suction device 2 through the conduit). At this time, the external dust suction device 1 of the suction pipe rack 2 507 is started, and suction is generated in the suction box 502 through the suction pipe rack 2 507, so that the powder in the collecting frame 501 is sucked into the suction box 502, and at the same time, the electromagnetic plate 2 503 is controlled to start, so that the metal particles in the powder are adsorbed on the electromagnetic plate 2 503, and other impurities are sucked into the dust suction device 1 through the suction pipe rack 2 507, and then the external dust suction device 1 of the suction pipe rack 2 507 is turned off.

[0073] During the sliding return process of the sliding frame 201 due to gravity, as described in the embodiment:

[0074] The electromagnetic plate 503 is closed, causing the metal particles on the electromagnetic plate 503 to slide downward until they are blocked by the hollow baffle 504. The second dust collection device connected to the connecting pipe 506 is then controlled to start, and the suction port 504a of the hollow baffle 504 generates suction through the suction pipe rack 505, thereby sucking the metal particles intercepted by the hollow baffle 504 into the second dust collection device connected to the connecting pipe 506. After the work is completed, the metal particles collected in the second dust collection device can be taken out.

[0075] According to the above working principle, we know that the present invention has the following effects:

[0076] The powder dropped when the brush plate 202 cleans the guide screen 102 is collected by the collecting frame 501, so as to avoid a large amount of powder falling onto the weak magnetic roller 301 at the same time, reduce the pressure of the weak magnetic roller 301 in collecting metal particles, ensure the adsorption effect of the weak magnetic roller 301 on the metal particles, and thus ensure the recovery rate of the metal particles; the powder collected in the collecting frame 501 is sucked out by the suction box 502, so as to avoid excessive accumulation and overflow of the powder in the collecting frame 501, which causes a large amount of powder to fall onto the weak magnetic roller 301 at the same time; the metal particles in the powder in the suction box 502 are adsorbed by the electromagnetic plate 2 503, so as to reduce the working pressure of the weak magnetic roller 301 and realize the separation of metal particles and impurities; when the dust suction device 1 connected to the suction pipe rack 2 507 is closed, the metal particles adsorbed on the electromagnetic plate 2 503 are sucked out and collected by the external dust suction device 2 through the connecting pipe 506, so as to avoid excessive accumulation of metal particles on the electromagnetic plate 2 503 affecting the adsorption effect and ensure the recovery rate of the metal particles.

[0077] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
