Description

Technical Field

[0001] This invention relates to the field of porcelain clay processing technology, specifically to a porcelain clay pretreatment device. Background Technology

[0002] Porcelain clay, also known as porcelain clay, white clay, or kaolin, is the main raw material for making ceramic ware, sculptures, vases, and other art pieces. Its processing involves washing, sedimentation, crushing, mixing, and iron removal. Iron removal is a crucial process because iron impurities reduce the whiteness of the clay, resulting in a darker color in fired ceramic products and affecting their appearance. During high-temperature firing, iron impurities form brown or black spots, which are particularly noticeable on celadon glazes and white porcelain, severely impacting the appearance quality of the ceramic products. Existing iron removal methods often involve placing multiple strong magnetic rods in a trough. The slurry flows through the trough and comes into contact with the magnetic rods to remove iron. However, this method is limited in its functionality and cannot effectively ensure sufficient contact between the slurry and the iron removal equipment, failing to achieve multi-stage and efficient iron removal. Summary of the Invention

[0003] The purpose of this invention is to provide a pretreatment device for porcelain clay materials to solve the problems mentioned in the background art.

[0014] Preferably, a drain pipe and a backwash pipe are provided at the bottom of the separation chamber. A diversion plate is fixedly connected inside the separation chamber. Multiple elliptical rods are fixedly connected to the top of the diversion plate. A piston plate is slidably connected to the outer side of the elliptical rods. The piston plate is slidably connected to the inner wall of the separation chamber. A spring is sleeved on the outer side of the elliptical rods and between the piston plate and the diversion plate. The elastic force of the spring is greater than the frictional force between the piston plate and the separation chamber.

[0015] Preferably, a water storage chamber is provided inside the separation chamber and above the piston plate. The water storage chamber is connected to an external high-pressure water source for pressurizing the inside of the water storage chamber. A discharge pipe is installed outside the separation chamber and below the piston plate.

[0016] Preferably, the piston plate has multiple water inlet cylinders fixedly connected to the top at equal intervals, and multiple water inlet holes are opened on the outer side of the water inlet cylinders. A sealing piston for blocking the water inlet holes is slidably connected inside the water inlet cylinders. Two limiting slide rods that are slidably connected to the top of the sealing piston are fixedly connected to the water inlet cylinders. A second spring is sleeved on the outer side of the limiting slide rods. A push rod for driving the sealing piston to move upward is fixedly connected to the bottom of the sealing piston. Multiple through holes for water outlet are opened on the piston plate at the positions corresponding to the water inlet cylinders. A one-way valve is installed at the bottom of the through hole at an angle for flushing the inner wall of the separation chamber.

[0017] Preferably, a locking hook is fixed to the top of the sealing piston, and an inlet / outlet sliding hole that cooperates with the locking hook is opened on the top of the water inlet cylinder. A limiting frame is fixed to the top of the water inlet cylinder, and a sliding locking block is slidably connected inside the limiting frame. A transverse sliding rod that is slidably connected to the limiting frame is fixed to one end of the sliding locking block. A spring is sleeved on the outer side of the transverse sliding rod and between the sliding locking block and the limiting frame. An interlocking hole for locking the locking hook is opened in the middle of the sliding locking block. An unlocking rod is fixed to the top of the inner wall of the separation chamber for driving the sliding locking block to move and limiting the piston plate.

[0018] Compared with existing technologies, the beneficial effects of this invention are as follows: The equipment is equipped with a pretreatment component and an electromagnetic separation component to achieve dual iron removal; the strong magnetic rod in the pretreatment cylinder directly adsorbs iron impurities in the slurry, and the electromagnetic separation component uses the strong magnetic field generated by the electromagnetic coil to further adsorb iron impurities in the separation chamber, greatly improving the iron removal effect; the design of the spiral blades in the pretreatment cylinder forms a spiral flow channel for the slurry, changing the slurry speed and direction, increasing the contact time between the slurry and the strong magnetic rod, and improving the iron removal efficiency; at the same time, the rotation of the spiral blades mixes and agitates the slurry, allowing the iron impurities to fully contact the strong magnetic rod, further improving the iron removal performance; the spiral blades slide against the filter screen surface during rotation, which can automatically scrape off the blockages on the outside of the filter screen, preventing the filter screen from clogging during transportation and ensuring smooth flow of the slurry; the strong magnetic rod is self-cleaning: when not in operation... The spiral blades can slide along the length of the strong magnetic rod to scrape away iron impurities adsorbed on the outside of the strong magnetic rod. During the cleaning process, the cylinder drives the movable cover plate downward, causing the spiral blades to slide along the outside of the strong magnetic rod with the cleaning holes, scraping away iron filings. At the same time, the cleaning nozzle washes the spiral blades, effectively cleaning impurities. After being treated by the pretreatment cylinder, the slurry enters the separation chamber. The diverter plate can evenly distribute the slurry, ensuring that the electromagnetic coil has a uniform iron removal effect on the slurry. After the secondary treatment, the iron impurities in the slurry are effectively removed, improving the slurry quality. After the treatment is completed, water is injected into the water storage chamber, causing the piston plate to move downward on the elliptical rod, scraping away impurities on the inner wall of the separation chamber. At the same time, when the piston plate is in a low position, the backwash pipe is opened, and water is used to flush the piston plate from bottom to top, further cleaning the separation chamber and ensuring the continuous and efficient operation of the equipment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] See also Figures 1-9This invention provides a technical solution: a pretreatment device for porcelain clay, comprising: a support box 1 made of iron; an electromagnetic sorting component placed inside the support box 1, the electromagnetic sorting component including a separation chamber 2 fixedly connected inside the support box 1, the separation chamber 2 being a circular tube structure, the separation chamber 2 being composed of a stainless steel tube with silicon steel sheets fixedly connected inside, and an electromagnetic coil 3 wrapped around the outside of the separation chamber 2; a pretreatment component placed outside the support box 1, the pretreatment component including a pretreatment cylinder 9 fixedly connected to the outside of the support box 1, a connecting pipe 7 fixedly connected to one side of the pretreatment cylinder 9, and a filter screen 8 installed at one end of the connecting pipe 7, the filter screen 8 and... The pretreatment cylinder 9 has the same and concentric inner diameter radius. The connecting pipe 7 is connected to the bottom of the separation chamber 2 through the conveying pipe 6. Multiple strong magnetic rods 14 are rotatably arranged inside the pretreatment cylinder 9. Non-magnetic spiral blades 15 are arranged on the outside of the strong magnetic rods 14. When the strong magnetic rods 14 rotate inside the pretreatment cylinder 9, the spiral blades 15 divide the inside of the pretreatment cylinder 9 into spiral flow channels. The rotating spiral blades 15 change the speed and direction of the mud. The spiral blades 15 and the filter screen 8 are cleaned by sliding. When the spiral blades 15 slide outside the strong magnetic rods 14, the spiral blades 15 scrape and clean 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 conveyed into the pretreatment cylinder 9 under high pressure. Under the conveying pressure, the slurry is conveyed from bottom to top in the pretreatment cylinder 9. During the conveying process, the spiral blades 15 divide the interior of the pretreatment cylinder 9 into spiral channels. The strong magnetic rods 14 are evenly distributed along the axis of the spiral blades 15 in the middle part of the spiral blades 15. When the slurry is conveyed along the spiral channel, it can make full contact with the strong magnetic rods 14. The strong magnetic rods 14 drive the spiral blades 15 to rotate along the axis of the pretreatment cylinder 9. The spiral blades 15 provide the slurry with a force opposite to the conveying pressure, thereby adjusting the speed and direction of the slurry and realizing the mixing and stirring of the slurry. The spiral motion generated by the rotation of the blades will drive the relative motion between the slurry and the strong magnetic rods 14. Due to the rotation of the spiral blades, the slurry path is spiral, and the slurry continuously flows around the magnetic rod. The opposing force of the spiral blades 15 slows down the flow velocity, thereby increasing the contact time between the slurry and the strong magnetic rod 14 and improving the iron removal efficiency. During the rotation of the spiral blades 15, their surface slides against the filter screen 8, thereby scraping the outer side of the filter screen 8 to prevent clogging during the conveying process. When the pretreatment cylinder 9 is not working, the spiral blades 15 slide along the length of the strong magnetic rod 14, scraping away iron impurities on the outer side of the strong magnetic rod 14. The iron-removed slurry enters the separation chamber 2. Under the strong magnetic action of the electromagnetic coil 3, the iron impurities inside the slurry are adsorbed onto the inner wall of the separation chamber 2, thus performing secondary iron removal.

[0032] In one embodiment, such as Figure 2 As shown, a shielding layer 4 is provided on the outside of the electromagnetic coil 3.

[0033] It should be noted that in this embodiment, the shielding layer 4 is made of silicon steel sheet, and a spiral cooling copper pipe is wound around the outside of the silicon steel sheet. The cooling medium circulates inside the copper pipe through a corresponding circulating pump, thereby cooling the electromagnetic coil 3 and the shielding layer 4.

[0034] In one embodiment, such as Figure 1 , 3 As shown in Figures 4 and 6, a drive unit for driving the strong magnetic rod 14 to rotate is installed on the top of the pretreatment cylinder 9. The drive unit includes a motor 20 and a connecting plate 38. The motor 20 is fixed to the outside of the support box 1, and the connecting plate 38 is rotatably installed inside the pretreatment cylinder 9. The strong magnetic rod 14 is fixed to the bottom of the connecting plate 38. The output end of the motor 20 is connected to the connecting plate 38 through a transmission belt assembly.

[0035] It should be noted that in this embodiment, the transmission belt assembly includes a small synchronous pulley fixed to the output end of the motor 20 and a large synchronous pulley connected to the connecting disc 38 via a rotating shaft. The large synchronous pulley and the small synchronous pulley are connected by a synchronous belt drive. The motor 20 drives the connecting disc 38 through the synchronous belt and the synchronous pulley. The connecting disc 38 drives the strong magnetic rod 14 to rotate around the axis of the pretreatment cylinder 9. In this way, the strong magnetic rod 14 drives its outer spiral blades 15 to rotate inside the pretreatment cylinder 9. Thus, the spiral blades 15 perform corresponding filter cleaning, slurry mixing, and spatial division of the pretreatment cylinder 9.

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

[0037] It should be noted that, in this embodiment, when cleaning the strong magnetic rod 14, the inlet and outlet valves corresponding to the pretreatment cylinder 9 are closed, and the movable cover plate 11 is driven downward by the cylinder 10. The movable cover plate 11 drives the limiting rod to slide on the outside of the pretreatment cylinder 9 to ensure the stable sliding of the movable cover plate 11. During the downward movement of the movable cover plate 11, the top and bottom of the spiral blade 15 are fixed with discs. The movable cover plate 11 drives the spiral blade 15 to move downward by the discs. The cleaning hole 17 slides on the outside of the strong magnetic rod 14, thereby scraping off the iron filings adsorbed on the outside of the strong magnetic rod 14 and the filtering device of the filter screen 8 by the spiral blade 15 and the discs. During the descent of the movable cover plate 11, the valve connected to the high-pressure water source of the cleaning nozzle 12 is opened. The cleaning nozzle 12 is evenly distributed at the end of the pretreatment cylinder 9, thereby rinsing the spiral blade 15 by the cleaning nozzle 12 to clean the impurities. After cleaning, the cylinder 10 drives the movable cover plate 11 to reset, thereby covering the bottom of the pretreatment cylinder 9 with the movable cover plate 11.

[0038] In one embodiment, such as Figure 1 , 2 As shown, the bottom of the separation chamber 2 is equipped with a drain pipe, a return pipe, and a backwash pipe. Both the drain pipe and the backwash pipe are fitted with corresponding valves. The return pipe is used to transport the slurry inside the separation chamber 2 to the slurry tank to be treated. A flow divider plate 5 is fixedly connected inside the separation chamber 2. Multiple non-magnetic stainless steel elliptical rods 13 are fixedly connected to the top of the flow divider plate 5. A piston plate 22 is slidably connected to the outer side of the elliptical rods 13. The piston plate 22 is slidably connected to the inner wall of the separation chamber 2. The outer side of the elliptical rods 13 and located on the piston plate 2... A spring 18 made of 304 stainless steel is sleeved between the piston plate 22 and the diversion plate 5. The elastic force of the multiple springs 18 is greater than the sum of the friction between the piston plate 22 and the separation chamber 2 and the weight of the piston plate 22 when it is full of water. The water storage chamber 16 is connected to an external high-pressure water source to pressurize the inside of the water storage chamber 16. A discharge pipe 21 is installed on the outside of the separation chamber 2 and below the piston plate 22. The discharge pipe 21 is located below the piston plate 22. When the slurry is discharged from the discharge pipe 21, it does not come into contact with the piston plate 22.

[0039] It should be noted that in this embodiment, after the slurry is treated by the pretreatment cylinder 9, it enters from the bottom of the separation chamber 2 through the connecting pipe 7 and the conveying pipe 6. The slurry is evenly distributed by the diversion plate 5. Under the strong magnetic action of the electromagnetic coil 3, 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 returned to the slurry tank through the return pipe at the bottom of the separation chamber 2. Then the return pipe valve is closed, the power supply of the electromagnetic coil 3 is turned off, the drain pipe valve is opened, and the valve connected to the high-pressure water at the top of the separation chamber 2 is opened, and water enters the water storage chamber 16. With the continuous accumulation of water... Under water pressure, piston plate 22 moves downward along elliptical rod 13. Piston plate 22 scrapes off impurities from the inner wall of separation chamber 2, causing iron impurities to be scraped off from the outside of separation chamber 2 and enter the drain pipe. When piston plate 22 is in a low position, the valve of backwash pipe is opened under the action of timer, and water is used to flush piston plate 22 from bottom to top. The flushing water is discharged through drain pipe.

[0040] In one embodiment, such as Figure 2 , 7 As shown in Figures 8 and 9, multiple water inlet cylinders 23 are equidistantly fixed to the top of the piston plate 22. Multiple water inlet holes 25 are opened on the outer side of each water inlet cylinder 23. A sealing piston 24 for sealing the water inlet holes 25 is slidably connected inside each water inlet cylinder 23. Two limiting slide rods 27, slidably connected to the top of the sealing piston 24, are fixedly connected to the top of the sealing piston 24. A spring 28 is sleeved on the outer side of each limiting slide rod 27. A push rod 26 for driving the sealing piston 24 upward is fixedly connected to the bottom of the sealing piston 24. Multiple through holes for water outlet are opened on the piston plate 22 corresponding to the positions of the water inlet cylinders 23. A one-way valve 37 is installed at an angle at the bottom of each 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. A locking hook 29 is opened on the top of the water inlet cylinder 23. The locking hook 29 is fitted with the inlet and outlet sliding hole 36. The top of the water inlet cylinder 23 is fixedly connected to the limit frame 31. The inside of the limit frame 31 is slidably connected to the sliding locking block 34. One end of the sliding locking block 34 is fixedly connected to the transverse sliding rod 32 which is slidably connected to the limit frame 31. A spring 33 is sleeved on the outside of the transverse sliding rod 32 and between the sliding locking block 34 and the limit frame 31. The middle of the sliding locking block 34 is provided with an interlocking hole 35 for locking the locking hook 29. The top of the inner wall of the separation chamber 2 is fixedly connected to the unlocking rod 30, which is used to drive the sliding locking block 34 to move and limit the piston plate 22. The unlocking rod 30, the interlocking hole 35 and the end of the locking hook 29 are all provided with a bevel structure. A drain pipe is provided on one side of the water storage chamber 16 for draining the water accumulated in the water storage chamber 16.

[0041] It should be noted that in this embodiment, with the valve of the discharge pipe 21 closed, water enters from the top of the water storage chamber 16. Because the sealing piston 24 blocks the water inlet 25, 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 spring 18. When the piston plate 22 moves to a position close to the diverter plate 5, the diverter plate 5 contacts the push rod 26. As the piston plate 22 continues to descend, the push rod 26 closes the sealing piston 24. Pushing upwards, the sealing piston 24 drives the locking hook 29 through the inlet / outlet sliding hole 36 and, under the action of its inclined surface, pushes it upwards from the bottom of the interlocking hole 35. Its inclined surface pushes the interlocking hole 35 to one side, causing it to move towards one end of the limiting frame 31. The water inlet hole 25 compresses the spring 33 outside the transverse sliding rod 32. When the end of the locking hook 29 passes through the middle of the interlocking hole 35, the spring 33 drives the interlocking hole 35 to reset, thereby locking the top of the sliding lock block 34 against the lower end of the locking hook 29. In this way, the locking hook 29 is locked. At this time, the sealing piston 24 drives the limiting slide rod 27 to compress the second spring 28, and the sealing piston 24 is misaligned with the water inlet 25. The water at the top of the piston plate 22 flows out through the water inlet 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 at the top of the piston plate 22 stops, and the water is sprayed from the one-way valve 37 onto the inner wall of the separation chamber 2. Under the reset action of the first spring 18, the piston plate 22 moves upward, and under the thrust of the first spring 18... Water enters the one-way valve 37 through the water inlet 25 and is continuously sprayed out. 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 to one end, so that the locking hook 29 is located in the middle of the interlocking hole 35. Under the reset of the spring 28, the sealing piston 24 seals the water inlet 25 again. At this time, the cylindrical part of the unlocking rod 30 contacts the sliding lock block 34, thereby limiting the position of the piston plate 22.
