Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment and solid-liquid mixing and dispersion technology. More specifically, this utility model relates to a magnetically driven rotating uniform distribution anti-settling device for solid-liquid suspension equipment. This utility model can be applied to chemical slurry processing equipment, mineral slurry equipment, material preparation slurry equipment, and other industrial equipment that requires maintaining a solid-liquid suspension state. Background Technology

[0002] Solid-liquid suspensions are multiphase mixtures formed by the uniform dispersion of solid particles in a liquid medium, widely used in chemical, environmental protection, mineral processing, metallurgy, energy, and new material preparation fields. In many production processes, it is necessary to maintain the solid particles in a stable suspension state within the liquid for extended periods, ensuring sufficient contact between the solid and liquid phases to guarantee uniform material concentration, stable mass transfer efficiency, and continuous operation of subsequent processes. Currently, methods for uniform distribution and anti-sedimentation treatment of solid-liquid suspensions in reaction tanks, storage tanks, and mixing equipment mainly employ mechanical stirring, circulating pump circulation, and fixed slurry distribution structures. Among these, mechanical stirring is the most widely used. It typically uses a motor to drive a stirring shaft to rotate, which in turn drives an impeller or stirring paddle to generate fluid circulation, disturbing the liquid phase and thus reducing the settling velocity of solid particles, improving the uniformity of the solid-liquid two-phase mixing.

[0003] However, existing solid-liquid suspension distribution equipment still has certain shortcomings in practical applications. On the one hand, traditional mechanical stirring structures usually adopt a central shaft drive method, and the stirring area is mainly concentrated near the impeller. For large circular reaction tanks or slurry storage equipment, low flow velocity areas are easily formed far from the stirring impeller, causing solid particles to gradually settle and form local dead zones. This results in uneven distribution of solid content in different areas inside the equipment, affecting the uniform distribution of solid particles.

[0004] Furthermore, existing solid-liquid suspensions often employ fixed feed pipes, annular distribution pipes, or fixed nozzle structures for feed distribution. After entering the equipment, the slurry primarily relies on its own diffusion for spatial distribution. Because solid-liquid suspensions typically have high solid content and high viscosity, they exhibit significant flow resistance, easily leading to pressure differences between different distribution locations. This results in higher flow rates near the inlet area and insufficient flow rates further away, causing localized issues such as excessively high concentrations or uneven distribution within the equipment. Simultaneously, fixed distribution structures lack active coverage capabilities, making them unsuitable for the uniform distribution requirements of large equipment with ample internal space.

[0005] Furthermore, for solid-liquid suspension systems containing corrosive media such as acids, alkalis, and salts, traditional mechanical rotating structures typically require a rotating shaft to pass through the equipment housing and a mechanical seal to achieve dynamic sealing. During long-term operation, mechanical seals are susceptible to corrosion from media, solid particles, and shaft vibration, leading to decreased sealing performance or even leakage. This not only affects the stability of continuous equipment operation but also increases maintenance costs.

[0006] Therefore, existing solid-liquid suspension equipment has problems such as limited distribution range of slurry after entering the equipment, uneven local concentration, easy sedimentation of solid particles, high energy consumption of stirring, easy failure of mechanical seals, and insufficient adaptability to corrosive environments, making it difficult to meet the requirements for long-term stable operation of solid-liquid two-phase systems with high solid content and high corrosivity.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0025] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0026] like Figures 1-10 As shown, a magnetically driven rotating uniform distribution anti-settling device for solid-liquid suspension equipment includes: The equipment housing 6 is provided with a drive assembly 5 and a feed pipe 4. The drive assembly 5 is provided with an external magnetic rotor 503. The equipment housing 6 includes an upper cylinder wall 601 and a lower cylinder wall 602, wherein the drive assembly 5 and the feed pipe 4 are provided on the upper cylinder wall 601. A bottom support circular perforated plate 1 is fixedly installed inside the equipment housing 6 by screws, and a plurality of distribution holes 101 are provided on the bottom support circular perforated plate 1; The rotating device 2 has its lower end rotatably connected to the bottom support circular perforated plate 1; the rotating device 2 can rotate around the central axis of the equipment housing 6 under the action of magnetic force, and its rotation trajectory matches the internal cross section of the equipment housing 6, which is used to expand the disturbance range of the solid-liquid suspension and improve the uniformity of solid particle distribution in the solid-liquid suspension inside the equipment housing 6. The rotating device 2 includes: The upper end of the hollow shaft 203 is rotatably connected to the feed pipe 4 via a rotary joint 201; An inner magnetic rotor 202 is fixedly mounted on the hollow shaft 203. The inner magnetic rotor 202 is coaxial with the outer magnetic rotor 503 and forms a magnetic coupling connection. The liquid collection tank 206 is a cylindrical structure. The liquid collection tank 206 is connected to the hollow shaft 203 and the feed pipe 4. The side of the liquid collection tank 206 has symmetrical openings. A fan-shaped liquid dispensing arm 205 is fixedly mounted on the liquid collection tank 206, and the fan-shaped liquid dispensing arm 205 is connected to the liquid collection tank 206 through an opening; a plurality of liquid dispensing plate openings 207 are provided on the bottom plate of the fan-shaped liquid dispensing arm 205. The scraper assembly 3 is mounted on the rotating device 2.

[0027] Working principle: The solid-liquid suspension enters the rotary joint 201 through the feed pipe 4, then enters the hollow shaft 203 through the rotary joint 201, and finally enters the collection tank 206 of the lower rotating device 2. The rotary joint 201 enables the rotary connection between the feed pipe 4 and the hollow shaft 203, allowing the hollow shaft 203 to rotate freely, while ensuring that the internal channels between the feed pipe 4 and the hollow shaft 203 are connected. This ensures that the solid-liquid suspension can enter from the feed pipe 4, pass through the interior of the rotary joint 201, flow into the hollow shaft 203, and finally enter the collection tank 206. Then, it flows into the fan-shaped distributing arm 205 through the opening on the collection tank 206, and is evenly distributed around the circumferential area of ​​the bottom supporting circular perforated plate 1 by the distributing plate openings 207 of the fan-shaped distributing arm 205.

[0028] The bottom support circular perforated plate 1 is used to support and limit the position of the rotating device 2, so that the rotating device 2 can rotate around the central axis of the magnetically driven rotating and uniformly distributed anti-settling device, and the solid-liquid suspension can enter the next stage equipment through the distribution hole 101. The drive assembly 5 drives the outer magnetic rotor 503 to rotate. Due to the magnetic coupling connection between the outer magnetic rotor 503 and the inner magnetic rotor 202, the coaxial power transmission from the outer magnetic rotor 503 to the inner magnetic rotor 202 is realized, so that the rotating device 2 can rotate synchronously with the outer magnetic rotor.

[0029] While the rotating device 2 rotates, it drives the fan-shaped distributing arms 205, the distributing plate openings 207, and the scraper assembly 3 to rotate circumferentially. Under the action of centrifugal force, the solid-liquid suspension in the collection tank 206 is evenly distributed and quickly enters each fan-shaped distributing arm 205. Then, it falls evenly onto the bottom support circular perforated plate 1 through the distributing plate openings 207 on the bottom plate of the fan-shaped distributing arm 205. As the rotating device 2 moves, the scraper assembly 3 pushes the suspension to flow circumferentially and scrapes the wall surface, so that the solid-liquid suspension in different areas inside the equipment is evenly exchanged. The solid-liquid suspension is subjected to continuous and uniform disturbance, thereby improving the distribution of the solid-liquid suspension within the interface of the equipment shell 6, reducing the possibility of solid particles depositing in local areas, and achieving a self-cleaning effect. This prevents the magnetically driven rotating uniform distribution anti-settling device from clogging and extends its service life.

[0030] In the above technical solution, the driving component includes: The motor 501 has a reducer 502 connected to its motor shaft. The output shaft of the reducer 502 is fixedly connected to the external magnetic rotor 503. The external magnetic rotor 503 is rotatably connected to the equipment housing 6. The rotational motion of the motor 501 is reduced by the reducer 502, which drives the external magnetic rotor 503 to rotate stably.

[0031] In the above technical solution, the rotating device 2 further includes: A connecting flange 204 is disposed between the hollow shaft 203 and the liquid collection tank 206. The connecting flange 204 is used to connect the hollow shaft 203 and the liquid collection tank 206. Two connecting posts 209 are symmetrically arranged on the side of the liquid collection tank 206. The connecting posts 209 are provided with connecting threads 210, and the connecting posts 209 are connected to the scraper assembly 3 through the connecting threads 210. A solid shaft 208 is fixedly mounted at the lower end of the liquid collection tank 206 by welding. The rotating device 2 is made of 316L stainless steel to meet the structural strength and corrosion resistance requirements in solid-liquid suspension environments. The outer diameter of the rotating device 2 can be adjusted according to the equipment size; a certain distance is maintained between the rotating device 2 and the inner wall of the equipment housing 6 to ensure the flow space of the solid-liquid suspension.

[0032] In the above technical solution, a support assembly is provided on the bottom support circular perforated plate 1, and the support assembly includes: The support bearing housing 102 houses a lower bearing 104 and an upper bearing 105. The solid shaft 208 is rotatably connected to the support bearing housing via the lower bearing and the upper bearing. The solid shaft 208 and the support assembly are fitted with a clearance fit or a sliding fit to ensure that the rotating device 2 can maintain stable rotation. A shoulder 103 is located at the upper end of the support bearing seat 102. The shoulder 103 is responsible for limiting the position, the lower bearing 104 is responsible for support, and the upper bearing 105 is responsible for guidance. The support assembly is used to guide and support the rotating device 2, so that the rotating device 2 maintains a stable rotation state, while reducing the offset and vibration of the rotating device 2 during the rotation process.

[0033] In the above technical solution, the scraper assembly 3 includes: The scraper main arm 303 has a threaded sleeve 302, and the connecting post 209 is connected to the threaded sleeve 302 by a connecting thread 210. The pressure plate 304 is detachably connected to the scraper main arm 303 by bolts 305; The scraper plate 301 is provided with an inclined mounting surface on the scraper main arm 303. The scraper plate 301 is fitted and mounted on the inclined mounting surface, and the scraper plate 301 is clamped and fixed between the pressure plate 304 and the scraper main arm 303. The scraper assembly 3 is arranged at intervals along the circumference of the liquid collection tank 206.

[0034] The scraper assembly 3 is used to push the solid-liquid suspension to form a circumferential flow and to scrape the wall of the equipment housing 6 when it moves with the rotating device 2, so that the solid-liquid suspension in different areas inside the equipment housing 6 can be uniformly exchanged; the scraper plate 301 is set close to the inner wall or bottom of the equipment housing 6 to reduce the adhesion and deposition of solid particles on the wall and bottom areas of the equipment housing 6.

[0035] A gap is maintained between the scraper blade 301 and the interior of the equipment housing 6 to avoid direct friction with the housing while ensuring good disturbance of the solid-liquid suspension near the wall. The length of the scraper assembly 3 can be set according to the equipment height and the characteristics of the solid-liquid suspension to achieve disturbance coverage in different areas.

[0036] In the above technical solution, the rotary joint 201 includes a fixed connection end and a rotary connection end that can rotate relative to the fixed connection end. The fixed connection end is connected to the feed pipe 4, and the rotary connection end is connected to the hollow shaft 203.

[0037] In the above technical solution, the distribution plate openings 207 on the bottom plate of the fan-shaped distribution arm 205 are linearly distributed in the radial direction. The density of the distribution plate openings 207 and the size of the distribution plate openings are proportional to the distance to the axis of the collection tank 206. This design ensures that the solid-liquid suspension is evenly distributed when it falls under the fan-shaped distribution arm.

[0038] In the above technical solution, the inner magnetic rotor 202 is covered with a protective cover, which is used to isolate the solid-liquid suspension inside the equipment housing 6 from the inner magnetic rotor 202. The equipment housing 6 includes one of stainless steel equipment housing, titanium alloy equipment housing, or polytetrafluoroethylene equipment housing.

[0039] In the above technical solution, for solid-liquid suspensions where it is not necessary to remove solid deposits on the wall surface, the scraper 301 is a polytetrafluoroethylene scraper to reduce wear caused by solid particle scouring and reduce frictional resistance when in contact with the inside of the equipment housing 6.
