The magnet attracts the round block, drives the compensation plate to leave the through groove, pulls the closed capsule to deform, and the magnet separates from the round block. Under the action of the elastic closed capsule, the crushed ore on the closed capsule is bounced upward to contact the metal crushing rod, and the metal crushing rod with magnetism attracts the magnetic material in the crushed ore; the metal crushing rod that attracts the magnetic material is driven to move to the receiving trough, and the circular block is driven to slide along the receiving trough to cover the outside of the metal crushing rod.

[0017] (3) The present invention drives the compensation plate to leave the through slot, pulling the closed bag to deform, and the gas enters the space between the closed bag and the rotating table through the one-way valve a. The magnet is separated from the round block. Under the action of the elastic closed bag, the air between the closed bag and the rotating table is squeezed out and ejected from the flow slot and the jet hole. The gas ejected from the jet hole blows toward the crushed ore in the crushing slot, causing the crushed ore to tumble, thereby enhancing the screening effect of the crushed ore.

[0018] (4) The present invention deforms the sealing bag by pulling it, and the gas enters the space between the sealing bag and the rotating table through the one-way valve a. The magnet is separated from the round block, and the air between the sealing bag and the rotating table is squeezed out by the elastic sealing bag, and is ejected from the flow groove and the jet hole. Since the top of the screening hole is closed, the gas ejected from the jet hole flows downward along the screening hole, blowing away the broken ore stuck in the screening hole, thereby cleaning the screening hole.

[0030] Embodiment Two: As Figures 1 - 15 shown, the same or corresponding components as those in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Two and Embodiment One lies in: The screening mechanism 4 includes: a rotating table 401, which is rotatably arranged in the shell 100, and is provided with a square groove 4011 and a plurality of screening holes 4012; a moving disk 402, which is rotatably arranged below the rotating table 401, and is provided with a through groove 4021 and a material dropping groove 4022; a closed capsule 403, which is arranged in the through groove 4021; and a toggle assembly 41, which is arranged on the moving disk 402.

A connecting shaft 407 is installed on the rotating table 401, and the rotating driving component d405 drives the connecting shaft 407 to rotate.

A seventh gear 410 is installed on the output end of the rotating driving component e406, and the sixth gear 409 and the seventh gear 410 are meshed.

[0032] A material receiving trough 102 is provided in the shell 100 , a linear driving member 418 is installed in the shell 100 , and a circular block 419 is installed at the output end of the linear driving member 418 ; a collecting chamber a104 and a collecting chamber b105 are provided in the shell 100 .

[0033] The toggle assembly 41 includes: a connecting block 411, which is arranged on the moving disk 402; a rotating driving member f412, which is installed on the connecting block 411; a swinging block 413, which is arranged at the output end of the rotating driving member f412; a compensation plate 414, which is installed on the swinging block 413; a magnet 415, which is installed on the compensation plate 414; and a round block 416, which is installed on the closed capsule 403. A flow groove 4013 and a plurality of jet holes 4014 are provided in the rotating table 401, and a one-way valve a417 is installed on the moving disk 402. A one-way valve b (not shown in the figure) is provided in the flow groove 4013 to achieve a one-way ventilation effect; an air escape groove (not shown in the figure) is opened in the moving disk 402 to allow the gas to enter the space between the closed capsule 403 and the rotating table 401 along the one-way valve a417. This is a conventional technical means in the field and will not be described in detail here.

[0034] In this embodiment, the toggle block 317 squeezes the connecting plate 303, so that the metal crushing rod 302 leaves the crushing slot 101 and is located between the two guide plates 106. The coil 305 is energized with current, and the metal crushing rod 302 is located in the coil 305, so that the metal crushing rod 302 has magnetism. The rotating drive member d405 drives the rotating table 401 to rotate, and the rotating drive member e406 drives the moving disk 402 to rotate, so that the square groove 4011 and the closed capsule 403 rotate synchronously to the bottom of the crushing groove 101. At this time, the crushed ore enters the square groove 4011 and falls on the closed capsule 403. The rotation drive f412 drives the swing block 413 to move, driving the compensation plate 414 to rotate into the through groove 4021. Then, the magnet 415 adsorbs the round block 416, driving the compensation plate 414 to leave the through groove 4021, pulling the closed capsule 403 to deform. When the magnet 415 is disengaged from the round block 416, under the action of the elastic closed capsule 403, the crushed ore on the closed capsule 403 is bounced upward to contact the metal crushing rod 302, and the magnetic metal crushing rod 302 adsorbs the magnetic materials in the crushed ore; The drive rotates the rotating rod 315, the rotating shaft 312, and the connecting rod 311 synchronously, driving the metal crushing rod 302 that adsorbs magnetic materials to move to the material receiving groove 102. The linear drive 418 drives the loop-shaped block 419 to slide along the material receiving groove 102 to cover the outside of the metal crushing rod 302. When the coil 305 is powered off, the metal crushing rod 302 loses its magnetism, and under the action of gravity, the magnetic materials enter the collection chamber b105 along the material receiving groove 102; Repeating this process can screen out the magnetic materials in the crushed ore.

[0035] In this embodiment, the drive inserts the compensation plate 414 into the through groove 4021 to make the closed capsule 403 flush with the top of the rotating table 401, squeezing out the crushed ore in the square groove 4011, driving the rotating table 401 and the moving disk 402 to rotate synchronously, and driving the screening hole 4012 to move below the crushing groove 101; At the same time, the drive makes the compensation plate 414 leave the through groove 4021, and the closed capsule 403 leaves the square groove 4011. At this time, the drive rotates the moving disk 402 so that the material dropping groove 4022 is located below the screening hole 4012, and the crushed ore in the crushing groove 101 falls into the collection chamber b105 along the screening hole 4012 and the material dropping groove 4022, completing the screening of the crushed ore.

[0036] In this embodiment, the upper part of the closed capsule 403 is closed. The rotation drive f412 drives the swing block 413 to move, driving the compensation plate 414 to rotate into the through groove 4021. Then, the magnet 415 adsorbs the round block 416, driving the compensation plate 414 to leave the through groove 4021, pulling the closed capsule 403 to deform. Gas enters the space between the closed capsule 403 and the rotating table 401 through the one-way valve a417. When the magnet 415 is disengaged from the round block 416, under the action of the elastic closed capsule 403, the air between the closed capsule 403 and the rotating table 401 is squeezed out and sprayed out from the flow groove 4013 and the air spraying holes 4014. The gas sprayed out from the air spraying holes 4014 blows towards the crushed ore in the crushing groove 101, causing the crushed ore to roll over and enhancing the screening effect on the crushed ore.

[0037] Drive the rotating table 401 and the moving disk 402 to rotate, so that the screening hole 4012 moves away from below the crushing groove 101. At this time, the upper part of the screening hole 4012 is closed, pulling the sealing capsule 403 to deform, and gas enters the space between the sealing capsule 403 and the rotating table 401 through the one-way valve a417. The magnet 415 is separated from the round block 416. Under the action of the elastic sealing capsule 403, the air between the sealing capsule 403 and the rotating table 401 is squeezed out and ejected from the flow groove 4013 and the air jet hole 4014. Since the upper part of the screening hole 4012 is closed, the gas ejected from the air jet hole 4014 flows downward along the screening hole 4012, blowing away the crushed ore stuck in the screening hole 4012 and cleaning the screening hole 4012.

[0038] Embodiment 3: This embodiment provides a production process of a magnesium oxide production device, including the following steps: Step 1, primary crushing process: Put the ore into the funnel 103, and the rotary drive member g201 drives the crushing roller 202 to rotate to perform primary crushing on the ore. The crushed ore enters the housing 100 along the filter plate 203, and then enters the crushing groove 101 along one side of the guide plate 106. There is a partition plate in the housing 100, and the partition plate is used to block the crushed ore to prevent the crushed ore from entering the receiving groove 102 along the other side of the guide plate 106; Step 2, enhanced crushing process: The rotary drive member a323 drives the rotating rod 315 to rotate, drives the first gear 321 to rotate, and further drives the toggle rod 316 to rotate, driving the toggle block 317 to squeeze the connecting plate 303. Under the action of the toggle block 317 and the elastic connecting member 304, the metal crushing rod 302 is driven to reciprocate along the chute 3011 to further crush the crushed ore in the crushing groove 101 and enhance the crushing effect; Step 3, magnetic separation process: The toggle block 317 squeezes the connecting plate 303, so that the metal crushing rod 302 leaves the crushing groove 101 and is located between the two guide plates 106. The coil 305 is energized, and the metal crushing rod 302 is located in the coil 305 to make the metal crushing rod 302 have magnetism; The rotary drive member d405 drives the rotating table 401 to rotate, and the rotary drive member e406 drives the moving disk 402 to rotate, so that the square groove 4011 and the sealing capsule 403 rotate synchronously to below the crushing groove 101. At this time, the crushed ore enters the square groove 4011 and falls on the sealing capsule 403; The rotary drive f412 drives the swing block 413 to move, driving the compensation plate 414 to rotate into the through groove 4021. Then, the magnet 415 adsorbs the round block 416, driving the compensation plate 414 to leave the through groove 4021, pulling the closed capsule 403 to deform. When the magnet 415 is disengaged from the round block 416, under the action of the elastic closed capsule 403, the crushed ore on the closed capsule 403 is bounced upward to contact the metal crushing rod 302, and the magnetic metal crushing rod 302 adsorbs the magnetic materials in the crushed ore; Drive the rotating rod 315, the rotating shaft 312, and the connecting rod 311 to rotate synchronously, driving the metal crushing rod 302 that adsorbs magnetic materials to move to the material receiving groove 102. The linear drive 418 drives the loop-shaped block 419 to slide along the material receiving groove 102 to cover the outside of the metal crushing rod 302. When the coil 305 is powered off, the metal crushing rod 302 loses its magnetism, and under the action of gravity, the magnetic materials enter the collection chamber b105 along the material receiving groove 102; By repeating this process, the magnetic materials in the crushed ore can be screened out; Step Four, screening process: Drive the compensation plate 414 to insert into the through groove 4021 to make the closed capsule 403 flush with the top of the rotating table 401, squeeze the crushed ore in the square groove 4011 out of the square groove 4011, drive the rotating table 401 and the moving disk 402 to rotate synchronously, and drive the screening hole 4012 to move below the crushing groove 101; At the same time, drive the compensation plate 414 to leave the through groove 4021, and the closed capsule 403 to leave the square groove 4011. At this time, drive the moving disk 402 to rotate so that the material dropping groove 4022 is located below the screening hole 4012, and the crushed ore in the crushing groove 101 falls into the collection chamber b105 along the screening hole 4012 and the material dropping groove 4022; Step Five, enhanced screening process: The upper part of the closed capsule 403 is closed. The rotary drive f412 drives the swing block 413 to move, driving the compensation plate 414 to rotate into the through groove 4021. Then, the magnet 415 adsorbs the round block 416, driving the compensation plate 414 to leave the through groove 4021, pulling the closed capsule 403 to deform. Gas enters the space between the closed capsule 403 and the rotating table 401 through the one-way valve a417. When the magnet 415 is disengaged from the round block 416, under the action of the elastic closed capsule 403, the air between the closed capsule 403 and the rotating table 401 is squeezed out and sprayed out from the flow groove 4013 and the air jet holes 4014. The gas sprayed out from the air jet holes 4014 blows towards the crushed ore in the crushing groove 101, causing the crushed ore to roll over and enhancing the screening effect on the crushed ore; Step Six, Cleaning Process: Drive the rotating table 401 and the moving disk 402 to rotate, so that the screening hole 4012 moves away from below the crushing groove 101. At this time, the upper part of the screening hole 4012 is closed. Pull the sealing capsule 403 to deform, and the gas enters the space between the sealing capsule 403 and the rotating table 401 through the one-way valve a417. The magnet 415 is separated from the round block 416. Under the action of the elastic sealing capsule 403, the air between the sealing capsule 403 and the rotating table 401 is squeezed out and sprayed out from the flow groove 4013 and the air spraying holes 4014. Since the upper part of the screening hole 4012 is closed, the gas sprayed out from the air spraying holes 4014 flows downward along the screening hole 4012, blowing away the crushed ore stuck in the screening hole 4012 and cleaning the screening hole 4012.
