[0002] Magnesium oxide (MgO) is an inorganic compound, an oxide of magnesium, and an ionic compound that is a white solid at room temperature. Magnesium oxide exists in nature as an ore, and its production requires extraction from the ore, necessitating the use of magnesium oxide production equipment.

[0010] A connecting frame is installed inside the housing, and a rotary drive component d and a rotary drive component e are installed on the connecting frame. A connecting shaft is installed on the rotating platform. The rotary drive component d drives the connecting shaft to rotate. A sleeve rod is installed on the moving disk. A sixth gear is installed on the sleeve rod. A seventh gear is installed at the output end of the rotary drive component e. The sixth gear and the seventh gear mesh.

[0011] The housing is provided with a receiving trough, and a linear drive is installed inside the housing. A loop block is installed at the output end of the linear drive. The housing is provided with a collection chamber a and a collection chamber b.

[0012] The actuating assembly includes: a connecting block disposed on the moving disk; a rotary drive f mounted on the connecting block; a swing block disposed at the output end of the rotary drive f; a compensation plate mounted on the swing block; a magnet mounted on the compensation plate; and a circular block mounted on the enclosed capsule.

[0014] The primary crushing mechanism includes: a rotary drive component g, which is mounted on the housing; a crushing roller, which is mounted at the output end of the rotary drive component g; and a filter plate, which is mounted inside the housing.

[0015] The beneficial effects of this invention are as follows: (1) The present invention drives the rotating rod to rotate, which in turn drives the first gear to rotate, which in turn drives the actuating block to press the connecting plate. Under the action of the actuating block and the elastic connecting piece, the metal crushing rod is driven to reciprocate along the chute to further crush the crushed ore in the crushing chute. By integrating the primary crushing mechanism, the enhanced crushing mechanism and the screening mechanism, the crushing and screening of magnesium oxide can be completed in one device, thereby improving the production efficiency of magnesium oxide.

[0016] (2) In this invention, the metal crushing rod is moved away from the crushing trough and placed between two guide plates by the pressing of the connecting plate by the actuating block. Current is passed through the coil, and the metal crushing rod is located inside the coil, making the metal crushing rod magnetic. The swing block is driven to move, and the compensation plate is driven to rotate into the through groove. The magnet attracts the round block, and the compensation plate is driven to leave the through groove. The closed bag is pulled to deform, and the magnet is separated from the round block. Under the action of the elastic closed bag, the crushed ore on the closed bag is bounced up and comes into contact with the metal crushing rod. The magnetic metal crushing rod 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. The loop block is driven to slide along the receiving trough and cover the outside of the metal crushing rod. The coil is de-energized and the metal crushing rod loses its magnetism. Under the action of gravity, the magnetic material enters the collecting chamber b along the receiving trough.

[0017] (3) In this invention, the compensation plate is driven away from the through groove, which pulls the closed bag to deform. 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 sprayed out from the flow groove and the jet hole. The gas sprayed out of the jet hole blows towards the crushed ore in the crushing groove, causing the crushed ore to tumble and enhancing the screening effect of the crushed ore.

[0018] (4) By pulling the closed bag to deform, the gas enters the space between the closed bag and the rotating platform through the one-way valve a. The magnet separates from the round block. Under the action of the elastic closed bag, the air between the closed bag and the rotating platform is squeezed out and sprayed out from the flow channel and the air jet hole. Since the top of the screening hole is closed, the gas sprayed out of the air jet hole flows down along the screening hole, blowing away the broken ore stuck in the screening hole and cleaning the screening hole.

It should be noted that: multiple sets of metal crushing rods 302 are provided, each set having a different size, allowing for different degrees of crushing of the ore; the rotating disk 301 has multiple power supplies that can power and de-energize the coils 305.

[0027] The drive assembly 31 includes: a connecting rod 311 mounted on the rotating disk 301; a rotating shaft 312 rotatably disposed within the connecting rod 311; a swing arm 313 mounted on the rotating shaft 312; a rotating rod 314 rotatably disposed on the swing arm 313; a rotating rod 315 rotatably disposed within the rotating shaft 312; a toggle rod 316 rotatably disposed on the swing arm 313; a toggle block 317 mounted on the toggle rod 316; and a linkage assembly 32 that drives the toggle rod 316 and the rotating rod 315 to rotate.

[0028] The linkage assembly 32 includes: a first gear 321, which is mounted on a toggle lever 316, a rotating lever 315, and a rotating lever 314, with the three first gears 321 meshing; a work frame 322, which is mounted on the housing 100; a rotary drive a323, which is mounted on the work frame 322 and drives the rotating lever 315 to rotate; a second gear 324, which is mounted on a connecting rod 311; and a third gear. 325, the third gear 325 is mounted on the rotating shaft 312; rotation drive b326, the rotation drive b326 is mounted on the work frame 322, the output end of the rotation drive b326 is equipped with a fourth gear 327, the fourth gear 327 meshes with the second gear 324; rotation drive c328, the rotation drive c328 is mounted on the work frame 322, the output end of the rotation drive c328 is equipped with a fifth gear 329, the fifth gear 329 meshes with the third gear 325.

[0029] In this embodiment, the rotary drive a323 drives the rotating rod 315 to rotate, which in turn drives the first gear 321 to rotate, thereby driving the actuating rod 316 to rotate, which in turn drives the actuating block 317 to press against the connecting plate 303. Under the action of the actuating block 317 and the elastic connecting member 304, the metal crushing rod 302 is driven to reciprocate along the slide groove 3011 to further crush the crushed ore in the crushing groove 101, thereby enhancing the crushing effect.

[0030] Example 2: Figures 1-15 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: The screening mechanism 4 includes: a rotating table 401, which is rotatably disposed within the housing 100, and has a square groove 4011 and a plurality of screening holes 4012; a moving disc 402, which is rotatably disposed below the rotating table 401, and has a through groove 4021 and a material discharge groove 4022; a sealing bladder 403, which is disposed within the through groove 4021; and a toggle assembly 41, which is disposed on the moving disc 402.

[0031] A connecting frame 404 is installed inside the housing 100. Rotary drive component d405 and rotary drive component e406 are installed on the connecting frame 404. A connecting shaft 407 is installed on the rotating table 401. Rotary drive component d405 drives the connecting shaft 407 to rotate. A sleeve rod 408 is installed on the moving disk 402. A sixth gear 409 is installed on the sleeve rod 408. A seventh gear 410 is installed at the output end of the rotary drive component e406. The sixth gear 409 and the seventh gear 410 mesh.

[0032] The housing 100 is provided with a receiving trough 102, and a linear drive 418 is installed inside the housing 100. A loop block 419 is installed at the output end of the linear drive 418. The housing 100 is provided with a collection chamber a104 and a collection chamber b105.

[0033] The actuating assembly 41 includes: a connecting block 411, which is mounted on the moving plate 402; a rotary drive f412, which is mounted on the connecting block 411; a swing block 413, which is located at the output end of the rotary drive f412; a compensation plate 414, which is mounted on the swing block 413; a magnet 415, which is mounted on the compensation plate 414; and a circular block 416, which is mounted on the enclosed bladder 403. The rotating table 401 has a flow groove 4013 and multiple air jets 4014 inside, and a one-way valve a417 is mounted on the moving plate 402. The flow channel 4013 is equipped with a one-way valve b (not shown in the figure) to achieve one-way ventilation; the moving plate 402 is provided with an air passage channel (not shown in the figure) so that the gas enters the space between the closed bag 403 and the rotating table 401 along the one-way valve a417. This is a conventional technical means in this field and will not be described in detail here.

[0034] In this embodiment, the actuating block 317 presses the connecting plate 303, causing the metal crushing rod 302 to leave the crushing groove 101 and be positioned between the two guide plates 106. Current is passed through the coil 305, and the metal crushing rod 302 is located inside the coil 305, making the metal crushing rod 302 magnetic. Rotary drive component d405 drives the rotating table 401 to rotate, and rotary drive component e406 drives the moving disk 402 to rotate, so that the square trough 4011 and the closed bag 403 rotate synchronously to the bottom of the crushing trough 101. At this time, the crushed ore enters the square trough 4011 and falls on the closed bag 403. The rotating drive component f412 drives the swing block 413 to move, drives the compensation plate 414 to rotate into the through groove 4021, then the magnet 415 attracts the round block 416, drives the compensation plate 414 to leave the through groove 4021, pulls the sealing bag 403 to deform, and the magnet 415 separates from the round block 416. Under the action of the elastic sealing bag 403, the crushed ore on the sealing bag 403 is bounced upward and comes into contact with the metal crushing rod 302. The magnetic metal crushing rod 302 attracts the magnetic material in the crushed ore. The drive rod 315, rotating shaft 312, and connecting rod 311 rotate synchronously, driving the metal crushing rod 302, which adsorbs magnetic materials, to move to the receiving trough 102. The linear drive component 418 drives the loop block 419 to slide along the receiving trough 102 and cover the outside of the metal crushing rod 302. When the coil 305 is de-energized, the metal crushing rod 302 loses its magnetism. Under the action of gravity, the magnetic material enters the collection chamber b105 along the receiving trough 102. This process is repeated to screen out the magnetic material in the crushed ore.

[0035] In this embodiment, the drive compensation plate 414 is inserted into the through groove 4021 so that the closed bag 403 is flush with the top of the rotating table 401, and the crushed ore in the square groove 4011 is squeezed out of the square groove 4011. The rotating table 401 and the moving disk 402 are driven to rotate synchronously, and the screening hole 4012 is driven to move to the bottom of the crushing groove 101. Simultaneously, the compensation plate 414 is driven to leave the through slot 4021, and the sealing bag 403 is driven to leave the square slot 4011. At this time, the driving disk 402 rotates, so that the material drop chute 4022 is located below the screening hole 4012. The crushed ore in the crushing trough 101 falls into the collection chamber b105 along the screening hole 4012 and the material drop chute 4022, thus completing the screening of the crushed ore.

[0036] In this embodiment, the top of the sealing capsule 403 is closed. The rotating 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 attracts the round block 416, driving the compensation plate 414 to leave the through groove 4021, pulling the sealing capsule 403 to deform. Gas enters the space between the sealing capsule 403 and the rotating table 401 through the one-way valve a417. The magnet 415 separates 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 jet hole 4014. The gas ejected from the jet hole 4014 blows towards the crushed ore in the crushing tank 101, causing the crushed ore to tumble and enhancing the screening effect of the crushed ore.

[0037] The rotating table 401 and the moving disk 402 are driven to rotate, causing the screening hole 4012 to move away from below the crushing trough 101. At this time, the area above the screening hole 4012 is closed. The sealing bladder 403 is pulled to deform, and gas enters the space between the sealing bladder 403 and the rotating table 401 through the one-way valve a417. The magnet 415 separates from the round block 416. Under the action of the elastic sealing bladder 403, the air between the sealing bladder 403 and the rotating table 401 is squeezed out and ejected from the flow channel 4013 and the air jet hole 4014. Since the area above 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] Example 3: This example provides a production process for a magnesium oxide production device, including the following steps: Step 1, Primary crushing process: The ore is placed into the funnel 103, and the rotating drive component g201 drives the crushing roller 202 to rotate to perform primary crushing of the ore. The crushed ore enters the shell 100 along the filter plate 203, and then enters the crushing trough 101 along one side of the guide plate 106. An isolation plate is provided in the shell 100 to block the crushed ore and prevent it from entering the receiving trough 102 along the other side of the guide plate 106. Step 2, Enhance the crushing process: The rotary drive component a323 drives the rotating rod 315 to rotate, which in turn drives the first gear 321 to rotate, thereby driving the actuating rod 316 to rotate, which in turn drives the actuating block 317 to press against the connecting plate 303. Under the action of the actuating block 317 and the elastic connecting component 304, the metal crushing rod 302 is driven to reciprocate along the slide 3011 to further crush the crushed ore in the crushing trough 101, thereby enhancing the crushing effect. Step 3, Magnetic Separation Process: The actuating block 317 presses the connecting plate 303, causing the metal crushing rod 302 to leave the crushing trough 101 and be positioned between the two guide plates 106. Current is passed through the coil 305, and the metal crushing rod 302 is located inside the coil 305, making the metal crushing rod 302 magnetic. Rotary drive component d405 drives the rotating table 401 to rotate, and rotary drive component e406 drives the moving disk 402 to rotate, so that the square trough 4011 and the closed bag 403 rotate synchronously to the bottom of the crushing trough 101. At this time, the crushed ore enters the square trough 4011 and falls on the closed bag 403. The rotating drive component f412 drives the swing block 413 to move, drives the compensation plate 414 to rotate into the through groove 4021, then the magnet 415 attracts the round block 416, drives the compensation plate 414 to leave the through groove 4021, pulls the sealing bag 403 to deform, and the magnet 415 separates from the round block 416. Under the action of the elastic sealing bag 403, the crushed ore on the sealing bag 403 is bounced upward and comes into contact with the metal crushing rod 302. The magnetic metal crushing rod 302 attracts the magnetic material in the crushed ore. The drive rod 315, rotating shaft 312, and connecting rod 311 rotate synchronously, driving the metal crushing rod 302, which adsorbs magnetic materials, to move to the receiving trough 102. The linear drive component 418 drives the loop block 419 to slide along the receiving trough 102 and cover the outside of the metal crushing rod 302. When the coil 305 is de-energized, the metal crushing rod 302 loses its magnetism. Under the action of gravity, the magnetic material enters the collection chamber b105 along the receiving trough 102. This process is repeated to screen out the magnetic material in the crushed ore. Step 4, Screening process: Drive the compensation plate 414 into the through groove 4021 so that the closed bag 403 is 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 to the bottom of the crushing trough 101. At the same time, the compensation plate 414 is driven to leave the through slot 4021, and the sealing bag 403 is driven to leave the square slot 4011. At this time, the driving disk 402 is rotated, so that the material drop chute 4022 is located below the screening hole 4012. The crushed ore in the crushing trough 101 falls into the collection chamber b105 along the screening hole 4012 and the material drop chute 4022. Step 5, Enhanced Screening Process: The top of the closed capsule 403 is closed. The rotating drive component f412 drives the swing block 413 to move, driving the compensation plate 414 to rotate into the through groove 4021. Then, the magnet 415 attracts 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. The magnet 415 separates 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 hole 4014. The gas sprayed out of the air jet hole 4014 blows towards the crushed ore in the crushing tank 101, causing the crushed ore to tumble and enhancing the screening effect of 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 tank 101. At this time, the area above the screening hole 4012 is closed. Pull the sealing bag 403 to deform, and gas enters the space between the sealing bag 403 and the rotating table 401 through the one-way valve a417. The magnet 415 separates from the round block 416. Under the action of the elastic sealing bag 403, the air between the sealing bag 403 and the rotating table 401 is squeezed out and sprayed out from the flow channel 4013 and the air jet hole 4014. Since the area above the screening hole 4012 is closed, the gas sprayed out of the air jet hole 4014 flows downward along the screening hole 4012, blowing away the broken ore stuck in the screening hole 4012 and cleaning the screening hole 4012.

9. The production process of a magnesium oxide production apparatus according to claim 8, characterized in that, Includes the following steps: Step 1, Primary Crushing Process: The ore is placed into the hopper, and the crushing roller is driven to rotate to perform primary crushing of the ore. The crushed ore then enters the shell. Step 2, Enhance the crushing process: Drive the rotating rod to rotate, which in turn drives the first gear to rotate, causing the actuating block to press against the connecting plate. Under the action of the actuating block and the elastic connecting piece, the metal crushing rod is driven to reciprocate along the chute to further crush the crushed ore in the crushing chute. Step 3, Magnetic Separation Process: The actuating block presses against the connecting plate, causing the metal crushing rod to leave the crushing trough and be positioned between the two guide plates. Current is passed through the coil, and the metal crushing rod is located inside the coil, making the metal crushing rod magnetic. The square trough and the sealing bag rotate synchronously to the bottom of the crushing trough, at which point the crushed ore enters the square trough and falls above the sealing bag. The drive compensation plate rotates into the through slot, the magnet attracts the round block, the drive compensation plate leaves the through slot, pulls the sealing bag to deform, the magnet separates from the round block, and under the action of the elastic sealing bag, the crushed ore on the sealing bag bounces up and contacts the metal crushing rod. The magnetic metal crushing rod attracts the magnetic material in the crushed ore. The metal crushing rod that drives the magnetic material adsorbing is moved to the receiving trough. The driving loop block slides along the receiving trough and covers the outside of the metal crushing rod. When the coil is de-energized, the metal crushing rod loses its magnetism. Under the action of gravity, the magnetic material enters the collection chamber b along the receiving trough; thus, the magnetic material in the crushed ore is screened out. Step 4, Screening process: Drive the compensation plate into the through slot so that the closed bag is flush with the top of the rotating table, squeeze the crushed ore in the square slot out of the square slot, drive the rotating table and the moving disk to rotate synchronously, and drive the screening hole to move to the bottom of the crushing slot. Drive the compensation plate away from the through slot and the sealing bag away from the square slot. At this time, drive the moving disc to rotate so that the material discharge chute is located below the screening hole. The crushed ore in the crushing chute falls into the collection chamber b along the screening hole and the material discharge chute. Step 5, Enhance the screening process: Drive the compensation plate away from the through groove, pull the sealing bag to deform, and the gas enters the space between the sealing bag and the rotating table through the one-way valve a. The magnet separates from the round block. Under the action of the elastic sealing bag, the air between the sealing bag and the rotating table is squeezed out and sprayed out from the flow groove and the air jet hole. The gas sprayed out of the air jet hole blows towards the crushed ore in the crushing tank, causing the crushed ore to tumble and enhancing the screening effect of the crushed ore. Step Six, Cleaning Process: Drive the rotating table and moving disc to rotate, so that the screening hole is away from below the crushing tank. At this time, the top of the screening hole is closed. Under the action of the elastic sealing bladder, the air between the sealing bladder and the rotating table is squeezed out and sprayed out from the flow channel and the air jet hole. Since the top of the screening hole is closed, the gas sprayed out of the air jet hole flows down along the screening hole, blowing away the crushed ore stuck in the screening hole and cleaning the screening hole.
