Description

Technical Field

[0001] The present invention relates to the technical field of porcelain clay processing, and particularly to a pretreatment device for porcelain clay materials. Background Art

[0002] Porcelain clay, also known as kaolin, white clay, and kaolinite, is the main raw material for making artworks such as ceramic wares, sculptures, and vases. During its processing, it needs to undergo processes such as washing, sedimentation, pulverization, mixing, and iron removal. Among them, iron removal is a very important process because iron impurities will reduce the whiteness of the porcelain clay, making the color of the fired ceramic products darker and affecting their aesthetics. During the high-temperature firing process, iron impurities will form brown or black spots, which are particularly obvious on celadon glaze and white porcelain, seriously affecting the appearance quality of the ceramic products. In the existing iron removal methods, multiple strong magnetic rods are placed in the trough, and the slurry is contacted with the strong magnetic rods during the process of flowing through the trough to remove iron from the slurry. However, the iron removal method and its corresponding functions are single, and the slurry cannot be effectively and fully contacted with the iron removal device, and multi-stage and efficient iron removal cannot be achieved.

[0012] Preferably, a cylinder is fixedly connected to the outside of the pretreatment cylinder. The output end of the cylinder is fixedly connected with a movable cover plate for sealing the bottom of the pretreatment cylinder. A limiting rod is fixedly connected to the outside of the movable cover plate. The metal rod is slidably connected to the pretreatment cylinder.

[0013] Preferably, a disc is fixedly connected to the bottom of the spiral blade. The center of the disc is rotatably connected to the center of the movable cover plate. A cleaning hole for slidably connecting with the strong magnetic rod is opened in the middle of the spiral blade. A feed pipe is installed on one side of the bottom of the pretreatment cylinder.

[0014] Preferably, a sewage discharge pipe and a backwash pipe are arranged at the bottom of the separation chamber. A flow dividing plate is fixedly connected inside the separation chamber. A plurality of elliptical rods are fixedly connected to the top of the flow dividing plate. A piston plate is slidably connected to the outside of the elliptical rod. The piston plate is slidably connected to the inner wall of the separation chamber. A first spring is sleeved outside the elliptical rod and between the piston plate and the flow dividing plate. The elastic force of the first spring is greater than the frictional force between the piston plate and the separation chamber.

[0015] Preferably, a water storage chamber is arranged above the piston plate inside the separation chamber. The water storage chamber is connected to an external high-pressure water source for pressurizing the inside of the water storage chamber.

[0017] Preferably, a locking hook is fixedly connected to the top of the sealing piston.

An interlocking hole for locking the locking hook is formed in the middle of the sliding locking block. An unlocking rod is fixedly connected to the top of the inner wall of the separation cavity, which is used to drive the sliding locking block to displace and limit the piston plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The device is provided with a pretreatment component and an electromagnetic separation component to achieve double iron removal. The strong magnetic rods in the pretreatment cylinder directly adsorb iron impurities in the slurry. The electromagnetic separation component uses the strong magnetic field generated by the electromagnetic coil to further adsorb iron impurities in the separation cavity, greatly improving the iron removal effect. The design of the spiral blade in the pretreatment cylinder forms a spiral flow channel for the slurry, changing the speed and direction of the slurry, increasing the contact time between the slurry and the strong magnetic rods, and improving the iron removal efficiency. At the same time, the rotation of the spiral blade mixes and stirs the slurry, enabling the iron impurities to fully contact the strong magnetic rods, further enhancing the iron removal performance. During the rotation process, the spiral blade is slidably connected to the surface of the filter screen, capable of automatically scraping the blockages outside the filter screen, preventing the filter screen from being blocked during transportation, and ensuring the smooth flow of the slurry. Self-cleaning of the strong magnetic rods: When not working, the spiral blade can be slid along the length direction of the strong magnetic rod to scrape the iron impurities adsorbed on the outside of the strong magnetic rod. During the cleaning process, the movable cover plate is driven downward by the cylinder, causing the spiral blade to drive the cleaning hole to slide outside the strong magnetic rod to scrape the iron filings. At the same time, the cleaning nozzle rinses the spiral blade, effectively cleaning the impurities. After the slurry is treated by the pretreatment cylinder, it enters the separation cavity. The flow dividing plate can evenly distribute the slurry, ensuring the uniform iron removal effect of the electromagnetic coil on the slurry. After secondary treatment, the iron impurities in the slurry are effectively removed, improving the quality of the slurry. After the treatment is completed, by injecting water into the water storage cavity, the piston plate moves downward on the elliptical rod to scrape the impurities on the inner wall of the separation cavity. At the same time, when the position of the piston plate is relatively low, the backwashing pipe opens, and the piston plate is rinsed from bottom to top by water to further clean the separation cavity, ensuring the continuous and efficient operation of the device.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 9, the present invention provides a technical solution: a pretreatment device for porcelain clay material, comprising: a support box body 1 made of iron; an electromagnetic separation component is placed inside the support box body 1, and the electromagnetic separation component includes a separation cavity 2 fixedly connected inside the support box body 1. The separation cavity 2 is a circular tube structure, and the separation cavity 2 is composed of silicon steel sheets fixedly connected inside a stainless steel tube. An electromagnetic coil 3 is wrapped outside the separation cavity 2; a pretreatment component is placed outside the support box body 1, and the pretreatment component includes a pretreatment cylinder 9 fixedly connected to the outside of the support box body 1. One side of the pretreatment cylinder 9 is fixedly connected with a connecting pipe 7. One end of the connecting pipe 7 is provided with a filter screen 8. The filter screen 8 has the same radius as the inner diameter of the pretreatment cylinder 9 and is concentric. The connecting pipe 7 is connected to the bottom of the separation cavity 2 through a feeding pipe 6. A plurality of strong magnetic rods 14 are rotatably arranged inside the pretreatment cylinder 9, and a non-magnetic conducting spiral blade 15 is arranged outside the strong magnetic rods 14; when the strong magnetic rods 14 rotate inside the pretreatment cylinder 9, the spiral blade 15 divides the inside of the pretreatment cylinder 9 into spiral channels. The rotating spiral blade 15 changes the speed and direction of the slurry, and the spiral blade 15 cleans the filter screen 8 through sliding contact with the filter screen 8; when the spiral blade 15 slides outside the strong magnetic rods 14, the spiral blade 15 scrapes and cleans the outside of the strong magnetic rods 14.

[0031] It should be noted that in this embodiment, a controller and a corresponding operation panel are provided. The porcelain clay slurry is transported into the pretreatment cylinder 9 under high pressure. Under the transportation pressure, the slurry is transported from bottom to top inside the pretreatment cylinder 9. During the transportation process, the spiral blade 15 divides the inside of the pretreatment cylinder 9 into spiral channels. The strong magnetic rods 14 are evenly distributed along the axis of the spiral blade 15 in the middle of the spiral blade 15. When the slurry is transported along the spiral channel, it can come into full contact with the strong magnetic rods 14, and the strong magnetic rods 14 drive the spiral blade 15 to rotate along the axis of the pretreatment cylinder 9. The spiral blade 15 provides a force opposite to the transportation pressure to the slurry, so as to adjust the speed and direction of the slurry, realize the mixing and stirring of the slurry, and the spiral movement generated by the rotation of the blade will promote the relative movement between the slurry and the strong magnetic rods 14. Due to the rotation of the spiral blade itself, the path of the slurry is spiral, and the slurry will continuously flow around the magnetic rods. And the force opposite to the spiral blade 15 can delay the flow rate of its flow channel, so as to increase the contact time between the slurry and the strong magnetic rods 14, improve the iron removal efficiency. And during the rotation of the spiral blade 15, its surface is slidably connected with the filter screen 8, so as to slide and scrape the outside of the filter screen 8 to prevent the filter screen 8 from being blocked during transportation. When the pretreatment cylinder 9 is not working, the spiral blade 15 is slid along the length direction of the strong magnetic rods 14, and the iron impurities outside the strong magnetic rods 14 are scraped off by the spiral blade 15. The slurry after iron removal and filtration enters the separation cavity 2, and under the strong magnetic action of the electromagnetic coil 3, the iron impurities inside the slurry are adsorbed on the inner wall of the separation cavity 2, so as to perform secondary iron removal.

[0032] In one embodiment, asFigure 2 As shown, a shielding layer 4 is disposed outside the electromagnetic coil 3.

[0033] It should be noted that in this embodiment, the shielding layer 4 is made of silicon steel sheets, and a cooling copper tube with a spiral structure is wound outside the silicon steel sheets. A cooling medium circulates inside the copper tube through a corresponding circulating pump, so as to cool the electromagnetic coil 3 and the shielding layer 4.

[0034] In one embodiment, as Figure 1 、 3 、4, and 6 show, a driving part for driving the rotation of the strong magnetic rod 14 is installed at the top of the pretreatment cylinder 9. The driving part includes a motor 20 and a connecting disk 38. The motor 20 is fixedly connected to the outside of the support box body 1. The connecting disk 38 is rotatably installed inside the pretreatment cylinder 9. The strong magnetic rod 14 is fixedly connected to the bottom of the connecting disk 38. The output end of the motor 20 is in transmission connection with the connecting disk 38 through a transmission belt assembly.

[0035] It should be noted that in this embodiment, the transmission belt assembly includes a small synchronous belt pulley fixedly connected to the output end of the motor 20 and a large synchronous belt pulley connected to the connecting disk 38 through a rotating shaft. The large synchronous belt pulley and the small synchronous belt pulley are in transmission connection through a synchronous belt. The motor 20 drives the connecting disk 38 through the synchronous belt and the synchronous belt pulley. The connecting disk 38 drives the strong magnetic rod 14 to rotate around the axis of the pretreatment cylinder 9. Thus, the strong magnetic rod 14 drives the spiral blade 15 outside it to rotate inside the pretreatment cylinder 9, so as to perform corresponding filter screen cleaning, slurry mixing, and space division of the pretreatment cylinder 9 through the spiral blade 15.

[0036] In one embodiment, as Figure 1 、 3 、4, 5, and 6 show, a cylinder 10 is fixedly connected to the outside of the pretreatment cylinder 9. The cylinder 10 is a self-locking cylinder. The output end of the cylinder 10 is fixedly connected to a movable cover plate 11 for sealing the bottom of the pretreatment cylinder 9. A limiting rod is fixedly connected to the outside of the movable cover plate 11. The metal rod is slidably connected to the pretreatment cylinder 9. A disk is fixedly connected to the bottom of the spiral blade 15. The center of the disk is rotatably connected to the center of the movable cover plate 11. A cleaning hole 17 slidably connected to the strong magnetic rod 14 is formed in the middle of the spiral blade 15. A feed pipe 19 is installed on one side of the bottom of the pretreatment cylinder 9. The feed pipe 19 is connected to a high-pressure grouting device, so as to introduce slurry into the pretreatment cylinder 9. A plurality of cleaning nozzles 12 are fixedly connected to the bottom of the pretreatment cylinder 9 and are inclined for cleaning the spiral blade 15.

[0037] It should be noted that when cleaning the strong magnetic rod 14 in this embodiment, the inlet and outlet valves corresponding to the pretreatment cylinder 9 are closed. The cylinder 10 drives the movable cover plate 11 to move downward. The movable cover plate 11 drives the limiting rod to slide outside the pretreatment cylinder 9, so as to ensure the stable sliding of the movable cover plate 11. During the downward movement of the movable cover plate 11, discs are fixedly connected to both the top and bottom of the spiral blade 15. The movable cover plate 11 drives the spiral blade 15 to move downward through the discs. The cleaning hole 17 slides outside the strong magnetic rod 14, so as to scrape off the iron filings adsorbed on the outside of the strong magnetic rod 14 and the devices filtered by the filter screen 8 through the spiral blade 15 and the discs. During the downward movement of the movable cover plate 11, the valve connecting the cleaning nozzle 12 to the high-pressure water source is opened. The cleaning nozzles 12 are evenly distributed at the end of the pretreatment cylinder 9, so as to wash the spiral blade 15 through the cleaning nozzles 12 and clean up the impurities. After the cleaning is completed, the cylinder 10 drives the movable cover plate 11 to reset, so as to cover the movable cover plate 11 on the bottom of the pretreatment cylinder 9.

[0038] In one embodiment, as Figure 1 、 2 shown, a sewage discharge pipe, a reflux pipe and an anti-flushing pipe are provided at the bottom of the separation chamber 2. Corresponding valves are installed on both the sewage discharge pipe and the anti-flushing pipe. The reflux pipe is used to transport the slurry inside the separation chamber 2 to the slurry pool to be treated. A flow dividing plate 5 is fixedly connected inside the separation chamber 2. A plurality of oval rods 13 made of non-magnetic stainless steel are fixedly connected to the top of the flow dividing plate 5. A piston plate 22 is slidably connected to the outside of the oval rod 13. The piston plate 22 is slidably connected to the inner wall of the separation chamber 2. A first spring 18 made of 304 stainless steel is sleeved outside the oval rod 13 and between the piston plate 22 and the flow dividing plate 5. The elastic force of the plurality of first springs 18 is greater than the sum of the friction between the piston plate 22 and the separation chamber 2 and the gravity of the water stored at the top of the piston plate 22. The water storage chamber 16 is connected to an external high-pressure water source for pressurizing the inside of the water storage chamber 16. An outlet pipe 21 is installed outside the separation chamber 2 and below the piston plate 22. The outlet pipe 21 is located below the piston plate 22. When the slurry is discharged from the outlet pipe 21, it does not contact the piston plate 22.

[0039] It should be noted that in this embodiment, after the slurry is processed by the pretreatment cylinder 9, it enters from the bottom of the separation chamber 2 through the connecting pipe 7 and the feeding pipe 6. The slurry is evenly distributed by the shunt plate 5. Under the strong magnetic action of the electromagnetic coil 3, the iron impurities are adsorbed on the inner wall of the separation chamber 2. The slurry after secondary treatment flows out through the discharge pipe 21. After the treatment is completed, the slurry inside the separation chamber 2 can be refluxed to the slurry pool through the reflux pipe at the bottom of the separation chamber 2. Then, the reflux pipe valve is closed, and then the power supply of the electromagnetic coil 3 is turned off. The sewage pipe valve is opened, and the valve connected to the high-pressure water at the top of the separation chamber 2 is opened. Water enters the water storage chamber 16. Under the continuous accumulation of water, under the action of water pressure, the piston plate 22 moves downward along the elliptical rod 13. The piston plate 22 scrapes the impurities on the inner wall of the separation chamber 2, so that the iron impurities are scraped from the outside of the separation chamber 2 into the sewage pipe. When the position of the piston plate 22 is relatively low, under the action of the timer, the valve of the backwash pipe is opened, and the piston plate 22 is flushed from bottom to top by water, and the flushing water is discharged through the sewage pipe.

[0040] In one embodiment, as Figure 2 、 7 、8, and 9 show, a plurality of water inlet cylinders 23 are fixedly connected to the top of the piston plate 22 at equal intervals. A plurality of water inlet holes 25 are formed on the outer side of the water inlet cylinder 23. A sealing piston 24 for blocking the water inlet holes 25 is slidably connected inside the water inlet cylinder 23. Two limiting slide rods 27 slidably connected to the water inlet cylinder 23 are fixedly connected to the top of the sealing piston 24. A second spring 28 is sleeved on the outer side of the limiting slide rod 27. A push rod 26 for driving the sealing piston 24 to move upward is fixedly connected to the bottom of the sealing piston 24. A plurality of through holes for water outlet are formed at the positions of the piston plate 22 corresponding to the water inlet cylinders 23. A one-way valve 37 is inclinedly installed at the bottom of the through hole for flushing the inner wall of the separation chamber 2. A locking hook 29 is fixedly connected to the top of the sealing piston 24. An access slide hole 36 matched with the locking hook 29 is formed at the top of the water inlet cylinder 23. A limiting frame 31 is fixedly connected to the top of the water inlet cylinder 23. A sliding locking block 34 is slidably connected inside the limiting frame 31. One end of the sliding locking block 34 is fixedly connected to a transverse slide rod 32 slidably connected to the limiting frame 31. A third spring 33 is sleeved on the outer side of the transverse slide rod 32 between the sliding locking block 34 and the limiting frame 31. An interlocking hole 35 for locking the locking hook 29 is formed in the middle of the sliding locking block 34. An unlocking rod 30 is fixedly connected to the top of the inner wall of the separation chamber 2 for driving the displacement of the sliding locking block 34 and limiting the piston plate 22. The ends of the unlocking rod 30, the interlocking hole 35, and the locking hook 29 are all provided with inclined surface structures. A drain pipe is provided on one side of the water storage chamber 16 for discharging the accumulated water in the water storage chamber 16.

[0041] It should be noted that in this embodiment, the valve of the discharge pipe 21 is closed, and water enters from the top of the water storage chamber 16. Since the sealing piston 24 blocks the water inlet hole 25, the upper part above the piston plate 22 is in a closed state. Under the action of water pressure, the piston plate 22 moves downward along the elliptical rod 13 and compresses the first spring 18. When the position of the piston plate 22 moves close to the flow dividing plate 5, the flow dividing plate 5 contacts the ejector rod 26. During the continuous downward movement of the piston plate 22, the ejector rod 26 pushes the sealing piston 24 upward. The sealing piston 24 drives the locking hook 29 to penetrate out of the inlet and outlet sliding hole 36 and is pushed out upward from the bottom of the interlocking hole 35 under the action of its inclined surface. Its inclined surface pushes the interlocking hole 35 to one side, causing the interlocking hole 35 to move towards one end of the limiting frame 31. The water inlet hole 25 compresses the third spring 33 outside the transverse sliding rod 32. When the end of the locking hook 29 penetrates through the middle of the interlocking hole 35, the third spring 33 drives the interlocking hole 35 to reset, thereby clamping the top of the sliding lock block 34 below the end of the locking hook 29 to limit and lock the locking hook 29. At this time, the sealing piston 24 drives the limiting sliding rod 27 to compress the second spring 28, and the sealing piston 24 is misaligned with the water inlet hole 25. The water at the top of the piston plate 22 flows outwards through the water inlet hole 25, the through hole in the middle of the piston plate 22, and the one-way valve 37. Under the action of the timer, the water injection to the top of the piston plate 22 stops, and the water sprays towards the inner wall of the separation chamber 2 from the one-way valve 37. Under the reset action of the first spring 18, the piston plate 22 moves upward. Under the thrust of the first spring 18, water enters the one-way valve 37 through the water inlet hole 25 and continues to spray. When the piston plate 22 moves to the top of the separation chamber 2, the unlocking rod 30 contacts the end of the sliding lock block 34. The inclined surface of the unlocking rod 30 pushes the sliding lock block 34 towards one end, so that the locking hook 29 is located in the middle of the interlocking hole 35. Under the reset of the second spring 28, the sealing piston 24 blocks the water inlet hole 25 again. At this time, the cylindrical part of the unlocking rod 30 contacts the sliding lock block 34 to limit the position of the piston plate 22.
