Description

Technical Field

[0001] This utility model relates to the field of Ru porcelain processing and preparation technology, specifically to a device for removing iron from slurry used in Ru porcelain production. Background Technology

[0002] Ru porcelain is a high-end art and collectible. With the booming development of the cultural industry and the improvement of people's living standards, the demand for Ru porcelain is becoming more and more diversified, and the requirements for its quality are also getting higher and higher. If the Ru porcelain slurry contains iron during the manufacturing process, colored spots are likely to appear on the surface of the fired porcelain, which will affect the quality of the finished Ru porcelain. Therefore, it is necessary to remove the iron from the slurry during the slurry preparation stage of Ru porcelain production.

[0003] The existing publicly available technology, application number CN201910458757.8, describes a Zhanggongxiang celadon-glazed Ru porcelain, comprising a body and a glaze. The body comprises kaolin, Mangchuan clay, Linru clay, and purple clay. The glaze comprises wind-cut clay, kaolin, gold clay, ilmenite, wollastonite, and calcined gemstone. The preparation method includes the following steps: mixing the components of the body evenly to obtain a slurry; filtering, removing iron, filtering mud, kneading mud, and shaping and refining to obtain a refined body; pre-firing to obtain a bisque body; mixing the components of the glaze evenly to obtain a slurry; filtering and removing iron from the slurry to obtain a glaze slurry; applying the glaze slurry to the bisque body to obtain a glazed body; and then firing the glazed body to obtain celadon-glazed Ru porcelain.

[0004] Currently, common iron removal devices typically involve inserting magnets into the slurry or allowing the slurry to flow through the magnets to remove iron. However, the contact area between the slurry and the magnet is relatively small, which can easily lead to incomplete iron removal and affect the overall iron removal quality. At the same time, the rapid flow of a large amount of slurry can cause excessively high impact speeds, which can wash away the outermost layer of iron filings and impurities, and prevent the magnet from effectively contacting the slurry, resulting in secondary pollution and incomplete iron removal, thus affecting the overall performance and leaving room for improvement.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a slurry iron removal device for Ru porcelain production, which has the following beneficial effects:

[0020] This invention employs an mounting ring, a cylinder, and a motor. When processing slurry, it is first added to the hopper, allowing it to flow out slowly. This ensures that the slurry makes contact with the magnetic rods on the mounting ring in small, frequent increments, guaranteeing stable impact and contact area. The staggered arrangement of magnetic rods on the mounting ring expands their working range, facilitating more thorough contact with the slurry. After the slurry is discharged, the cylinder and motor rotate and move the mounting ring up and down, allowing the magnetic rods on its surface to contact different parts of the slurry, further expanding the overall contact area and facilitating more thorough iron removal. This improves the overall iron removal quality, offering advantages such as comprehensive iron removal, excellent iron removal effect, and a wide iron removal area. Attached Figure Description

[0029] According to an embodiment of this utility model, an iron removal device for slurry in Ru porcelain production is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1 , Figure 3 and Figure 4As shown, a slurry iron removal device for Ru porcelain production according to an embodiment of the present invention includes a slurry cylinder 1 and support legs 17. Support seats 15 are symmetrically welded to the top positions of both sides of the slurry cylinder 1. A support rod 4 is installed at the top position of the support seat 15. A fixing plate 5 is fixedly installed at the top position of the support rod 4. A cylinder 7 is installed at the middle position of the top of the fixing plate 5. The telescopic end of the cylinder 7 passes through one side of the fixing plate 5 and is connected to a lifting rod 8. The fixing plate 5 is installed at the bottom position of the lifting rod 8. Several sets of limiting rods 6 are symmetrically installed on both sides of the top of the fixing plate 10, and the limiting rods 6 are slidably connected to the fixing plate 5. A [missing information - likely a device or mechanism] is installed at the middle position of the top of the fixing plate 10. Motor 9, the output end of motor 9 passes through one side of fixed plate 5 and is connected to rotating shaft 11. Several sets of mounting rings 2 are symmetrically installed at the bottom of rotating shaft 11, and several sets of magnet rods 3 are installed around the inner surface of mounting rings 2. Slurry cylinder 1: Slurry cylinder 1 is made of 304 stainless steel welded and formed, the wall thickness can be set by the user, such as 5mm, the inner wall is polished to prevent slurry adhesion; support seats 15 are symmetrically welded to the top of both sides, and the surface of support seats 15 is machined with M12 threaded holes for mounting support rods 4; support seats 15, support rods 4 and fixed plate 5 form a support system to bear the weight of moving parts such as cylinder 7 and motor 9; stainless steel slurry cylinder 1 avoids Prevents slurry corrosion, extends equipment life, and reduces maintenance costs; Cylinder 7 installation: Cylinder 7 (e.g., model SC-100-100) is fixed to the top of the fixed plate 5 via a flange. The cylinder body is connected to the fixed plate 5 with M16 bolts. The telescopic end is connected to the lifting rod 8 via a coupling. The lifting rod 8 has a diameter of approximately 40mm and is chrome-plated to prevent slurry corrosion; Limiting rods 6: Two sets of limiting rods 6 are installed on each side of the fixed plate 10, with a clearance fit (0.1-0.2mm) with the guide holes of the fixed plate 5 to prevent the fixed plate 10 from rotating or shifting; Cylinder 7 drives the lifting rod 8 to move up and down, and the limiting rods 6 slide within the guide holes of the fixed plate 5 to ensure stability. The verticality of the fixed plate 10 is ≤0.5mm, preventing uneven contact between the magnet rod 3 and the slurry caused by the tilting of the mounting ring 2; Three-dimensional iron removal: the cylinder 7 drives the mounting ring 2 to move up and down, cooperating with the rotation of the motor 9, so that the magnet rod 3 forms a three-dimensional motion trajectory in the slurry cylinder 1, increasing the contact area compared with traditional fixed magnets; Precise control: the speed of the cylinder 7 is adjustable to adapt to different slurry viscosities, ensuring that the contact time between the magnet rod 3 and the slurry is ≥2 seconds / time, improving the iron removal efficiency; Motor 9 is fixed: the motor 9 is fixed to the fixed plate 10 by a shock-absorbing pad, and the output shaft and the rotating shaft 11 are connected by a flexible coupling, allowing radial deviation ≤0.1mm and axial deviation ≤0.0.05mm; Mounting ring 2 assembly: Two sets of mounting rings 2 are symmetrically installed at the bottom of the rotating shaft 11 and fixed to the rotating shaft 11 by key connection. Twelve magnet rods 3, which can be made of permanent magnets, are evenly distributed on the inner wall of the rings and fixed with countersunk screws. The motor 9 drives the rotating shaft 11 to rotate at a low speed of 10-30 r / min. The magnet rods 3 of the upper and lower mounting rings 2 are arranged alternately (misalignment angle 30°), forming a three-dimensional magnetic field area. When the slurry falls, it is attracted by the multi-layered magnetic field. Magnetic field coverage: The alternately arranged magnet rods 3 greatly increase the magnetic field coverage area to the cross-sectional area of ​​the slurry cylinder 1, thus improving the iron impurity adsorption rate.

[0031] like Figure 1 and Figure 2 As shown, a hopper 13 is snapped onto the top of the slurry cylinder 1. A storage trough 12 is located inside the hopper 13. Several sets of flow holes 14 are evenly distributed at the bottom of the storage trough 12. A hollow tube is located in the center of the storage trough 12, and the hollow tube is situated on the outer periphery of the rotating shaft 11. The hopper 13 is a frustum-shaped cone (e.g., upper diameter 500mm, lower diameter 300mm), connected to the top of the slurry cylinder 1 by snap-fit ​​fasteners with a spacing of, for example, 150mm, using a silicone sealing ring. (Compression 2mm) Leak-proof; The hopper 13, which is smaller at the top and larger at the bottom, causes the slurry to fall in a funnel shape and be evenly distributed to the area of ​​the mounting ring 2 through the flow hole 14. The gap between the hollow tube and the rotating shaft 11 ensures that the rotating shaft 11 can rotate freely, while preventing the slurry from directly impacting the shaft; Flow control: The flow hole 14 limits the slurry flow rate to ensure that the contact time between the slurry and the magnet rod 3 is guaranteed, such as ≥3 seconds, to avoid high-speed impact causing iron filings to fall off (the flow rate of the traditional device is 0.5m / s, and the contact time is only 0.5 seconds).

[0032] like Figure 1 As shown, discharge pipes 16 are symmetrically installed at the bottom of both sides of the slurry cylinder 1. The discharge pipes 16 are made of DN80 PVC pipes and are installed at the bottom of both sides of the slurry cylinder 1 at an angle of 45° to the horizontal plane (the figure shows the horizontal state for easy understanding of the structure). A filter screen (0.5mm aperture, not shown) is installed inside the pipe to prevent the discharge of iron filings that have not been removed. The inclined design of the discharge pipe 16 utilizes gravity for discharge, and the filter screen intercepts residual iron filings. The staggered magnetic rods 3 cause the slurry to pass through different magnetic field areas twice, thereby improving the secondary iron removal efficiency and meeting the requirements of high-grade Ru porcelain raw materials.

[0033] like Figure 1 As shown, several sets of support legs 17 are symmetrically installed on both sides of the bottom of the slurry cylinder 1. There are a total of 4 sets of support legs 17. They are made of Q235 steel and welded to the four corners of the bottom of the slurry cylinder 1. Adjustable feet (adjustment range 0-50mm) are added to the bottom of the legs and fixed to the ground by expansion bolts to ensure that the device is level. The adjustable feet of the support legs 17 can adapt to different ground flatness and prevent the magnetic rod 3 from being displaced due to device vibration, thus ensuring the accuracy of the iron removal position.

[0034] like Figure 1 and Figure 3 As shown, the magnet rods 3 on the surfaces of the upper and lower sets of mounting rings 2 are staggered. The magnet rods 3 are staggered: the magnet rods 3 on the upper and lower mounting rings 2 are installed in a staggered manner, with a spacing of 30mm between the upper magnet rods 3 and 25mm between the lower magnet rods 3, forming a gradient magnetic field to enhance the adsorption effect. Gradient magnetic field: the staggered arrangement makes the magnetic field strength gradually change from 1.2T in the upper layer to 1.5T in the lower layer, which can adapt to the adsorption of iron filings of different particle sizes.

[0035] like Figure 1 and Figure 2 As shown, hopper 13 has a structure that is smaller at the top and larger at the bottom. In the slurry treatment stage: the slurry falls evenly from hopper 13 through flow holes 14, first contacting the magnetic rods 3 of the upper mounting ring 2, where iron filings are initially attracted; unattracted iron filings fall with the slurry and contact the staggered magnetic rods 3 of the lower layer, where they are attracted a second time; cylinder 7 drives the mounting ring 2 to move up and down at a speed of 20 mm / s, and motor 9 rotates at 15 r / min to expand the magnetic field coverage; in the iron removal strengthening stage: after all the slurry has fallen into the slurry cylinder 1, cylinder 7 drives the mounting ring 2 to reciprocate up and down in the slurry (e.g., a stroke of 80 mm), and motor 9 rotates at a low speed (10 r / min), continuously attracting for 3-5 minutes; under the action of the magnetic field, iron... The iron filings gather along the axial direction of the magnetic rod 3, forming an iron filings chain to avoid secondary pollution. During the discharge and cleaning stage: the discharge pipe 16 valve is opened to discharge the iron-removed slurry. The remaining iron filings are moved out of the slurry cylinder 1 along with the magnetic rod 3 and then manually cleaned. The hopper 13 can be quickly disassembled to clean the storage tank 12 and the flow hole 14 to prevent the slurry from drying out. Through the linkage of the cylinder 7 and the motor 9, the staggered magnetic field design, and the slurry uniform distribution system, this device achieves efficient iron removal of Ru porcelain slurry, meeting the stringent requirements of high-grade Ru porcelain for raw material purity, while reducing maintenance costs and labor intensity. Since the linkage of the cylinder 7 and the motor 9 can be achieved through an external controller and program design, it will not be described in detail.

[0036] like Figure 1 and Figure 2 As shown, the hollow tube is larger than the rotating shaft 11. Hollow tube installation: The hollow tube (e.g., 120mm in diameter) is welded to the center of the storage tank 12, with its height exceeding the top of the hopper 13 by 50mm and a gap of 5mm between it and the rotating shaft 11 to prevent slurry from entering the bearing of the rotating shaft 11.

[0037] like Figure 1 and Figure 2 As shown, the height of the hollow tube is greater than the height of the hopper 13. Anti-interference design: The height of the hollow tube exceeds that of the hopper 13 to prevent slurry from splashing into the bearing of the rotating shaft 11, thus extending the bearing life.

[0038] Working Principle: In actual use, personnel can add the Ru porcelain slurry requiring iron removal to the storage tank 12 in the hopper 13 at the top of the slurry cylinder 1. The slurry is then discharged slowly and orderly through the flow hole 14 at the top of the storage tank 12, avoiding excessive impact and insufficient contact with the magnetic rods 3 caused by a large simultaneous outflow of slurry, thus ensuring the quality of iron removal. The outflowing slurry then contacts the magnetic rods 3 on the surface of the mounting ring 2. The magnetism of the magnetic rods 3 attracts iron, cobalt, nickel, and other substances inside, thereby achieving iron removal. The upper and lower sets of magnetic rods 3 are staggered, allowing slurry not in contact with the upper magnetic rods 3 to contact the lower ones, thus expanding the overall contact area and improving the overall iron removal quality. After the slurry falls and contacts the magnetic rods for iron removal, it all falls into the interior of the slurry cylinder 1. The device is positioned so that the lifting rod 8 can be moved by the operation of the cylinder 7, which in turn moves the entire fixed plate 10 up and down, thereby moving the mounting ring 2 up and down along the slurry cylinder 1. This allows the magnetic rod 3 to contact the slurry at different positions, further expanding the overall contact area. At the same time as it moves up and down, the slow rotation of the motor 9 can further drive the magnetic rod 3 to contact the slurry at different positions, no longer limited to slurry treatment at a single position. This effectively increases the overall contact area, thereby more fully removing iron and improving the overall quality of use. The slurry after iron removal can be discharged through the discharge pipe 16 at the bottom, and the magnetic rod 3 can be removed from the slurry cylinder 1 for manual removal of impurities, facilitating subsequent use. The device as a whole has the advantages of comprehensive iron removal, good iron removal effect, and wide iron removal area.
