Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon filtration and decolorization devices, specifically an activated carbon filtration and decolorization device. Background Technology

[0002] Activated carbon filtration and decolorization devices are widely used in the food industry (such as syrup and juice decolorization), pharmaceutical industry (such as impurity removal from pharmaceutical solutions), and chemical industry (such as solvent purification). Their core function is to remove pigments, odors, and trace impurities from liquids through the adsorption of activated carbon, ensuring the purity and quality of subsequent products. The core collaborative requirements for this type of device are: first, uniform filtration, ensuring the entire surface of the liquid to be treated is covered by the activated carbon filter plate to avoid localized saturation while the edges remain underutilized; second, convenient maintenance, enabling quick replacement of the activated carbon filter plate to reduce downtime; third, high efficiency and stability, ensuring a continuous and smooth filtration process and adapting to the processing needs of liquids with different viscosities; and fourth, structural adaptability, with the filter components and feeding system working in tandem to prevent liquid stagnation or blockage.

[0003] Currently, the existing activated carbon filtration and decolorization devices in the industry mainly adopt the traditional technical solution of fixed feed inlet and static filter plate. Specifically, the filter tank is mostly cylindrical or square in structure, with a single fixed feed inlet at the top. The liquid drips directly and vertically into the center of the filter plate. The filter plate adopts a multi-layer stacked design, but is directly fixed to the inner wall of the tank or the bottom support by bolts. Some simple devices are even equipped with only a single layer of filter plate and no special feed dispersion structure. This solution has become the mainstream choice for small and medium-sized production due to its simple structure and low cost.

[0004] A single fixed feed inlet causes the liquid to flow concentrated in the central area of ​​the filter plate, resulting in rapid saturation of the activated carbon in the center, while the peripheral areas remain underutilized for a long time. The overall utilization rate of the filter plate is only 40%-50%. Once the center is saturated, the filter plate needs to be replaced prematurely, which not only increases the cost of activated carbon consumption but also causes fluctuations in decolorization effect due to the decrease in local adsorption capacity, resulting in the problem of "achieving decolorization standards in the first half but exceeding the standard for pigment residue in the second half". Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an activated carbon filtration and decolorization device. This solves the problem of a fixed single inlet causing liquid to concentrate in the central area of ​​the filter plate, leading to rapid saturation of the activated carbon in the center while the peripheral areas remain underutilized, resulting in an overall filter plate utilization rate of only 40%-50%. Once the center is saturated, the filter plate needs to be replaced prematurely, increasing activated carbon consumption costs and causing fluctuations in decolorization efficiency due to decreased local adsorption capacity, resulting in a situation where "the first half of the decolorization process meets standards, but the second half results in excessive pigment residue."

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-5 This utility model provides a new technical solution: an activated carbon filtration and decolorization device, including a support plate 1: two support plates 1 are arranged in a front-to-back correspondence, and a circular sleeve 9 is fixedly connected to the upper surface of the two support plates 1. A cylinder 2 is fixedly connected to the opposite surfaces of the two support plates 1. The support plate 1 is the core bearing foundation of the device. The front-to-back correspondence forms a symmetrical support structure, providing stable installation support for the circular sleeve 9 and the conical filter tank 10, and at the same time providing lateral fixation for the cylinder 2, ensuring the overall stability of the device when the cylinder drives the circular cover 8 to rise and fall.

[0035] Circular sleeve 9: Circular sleeve 9 is fixedly connected to the upper surface of the two support plates 1. The inner wall of circular sleeve 9 is fixedly fitted with a conical filter tank 10. The upper surface of circular sleeve 9 is in contact with the lower surface of circular cover 8. Circular sleeve 9 provides precise fitting and fixation for conical filter tank 10, restricting its lateral displacement, and at the same time provides a bottom positioning reference for circular cover 8, ensuring that circular cover is coaxial with conical filter tank 10 when sliding.

[0036] Conical filter tank 10: The conical filter tank 10 is fixedly sleeved on the inner wall of the circular sleeve 9. A rotating conveying assembly is provided on the conical filter tank 10. Three activated carbon filter plates 11 are slidably connected to the inner wall of the conical filter tank 10. A discharge pipe communicating with the interior is fixedly connected to the lower surface of the conical filter tank 10. The conical filter tank 10 is the core container for filtration and decolorization. The conical structure facilitates the flow of filtered liquid along the inner wall to the discharge pipe, reducing residue. The inner wall provides sliding installation space for the activated carbon filter plates 11, realizing the adsorption and filtration of pigments and impurities.

[0037] Circular cover 8: Four fixing screws 13 are fixedly connected to the top inside the circular cover 8. The opposite sides of the circular cover 8 are fixedly connected to two connecting plates 3. The circular cover 8 is an integrated carrier for rotating material conveying and fixing the filter plate. It lifts and lowers with the cylinder 2 to realize the picking and putting of the filter plate. At the same time, it carries the protective cover 7 and the fixing screws 13 to ensure that the rotating parts and the fixed parts work together.

[0038] Protective cover 7: The protective cover 7 has a fixed connection to the drive motor 18. The protective cover 7 provides a closed protective space for the internal drive motor 18 and gear 17 to prevent liquid or impurities from entering and affecting the transmission. At the same time, it provides through support for the rotating tube 15 to ensure its stable rotation.

[0039] Rotating tube 15: A gear 17 is fixedly sleeved on the outer wall of one end of the rotating tube 15 inside the protective cover 7. The rotating tube 15 is the core shaft for liquid conveying and rotating material distribution. It receives the liquid conveyed by the connecting tube 6 and diverts it to the conveying tube 16. It is driven to rotate through gear meshing to achieve uniform circumferential distribution of liquid.

[0040] Connecting pipe 6: Connecting pipe 6 is a transitional conveying component between external liquid and rotating pipe 15. It is fixed to the circular cover 8 by L-shaped fixing plate 4 to prevent it from rotating with rotating pipe 15 and to ensure stable liquid input.

[0041] L-shaped fixing plate 4: L-shaped fixing plate 4 provides rigid fixation for connecting pipe 6, restricts the rotational freedom of connecting pipe 6, and allows rotating pipe 15 to rotate independently to distribute the material, while not affecting the smooth delivery of liquid.

[0042] External feeding connection pipe 5: External feeding connection pipe 5 is used to connect to the external liquid to be filtered conveying pipe, providing a raw material input interface for the device, ensuring that the liquid to be filtered can flow accurately into the connection pipe 6 and enter the subsequent filtration process.

[0043] Feed pipe 16: The feed pipe 16 rotates synchronously with the rotating pipe 15, diverting the liquid in the rotating pipe to multiple discharge pipes 14, expanding the liquid spraying range, and avoiding the liquid from concentrating and flowing through a local area of ​​the filter plate.

[0044] Discharge pipe 14: The discharge pipe 14 evenly sprays the liquid conveyed by the conveying pipe 16 onto the activated carbon filter plate 11 inside the conical filter tank 10. Through the distribution of multiple discharge pipes, the uniformity of liquid coverage on the filter plate is further improved, and the utilization rate of activated carbon is increased.

[0045] Gear 17: Two gears 17 mesh together. Gear 17 is a power transmission component that transmits the rotational power of the drive motor 18 to the rotating tube 15. Through meshing transmission, the rotational speed of the rotating tube is kept stable, and synchronous rotation of the fabric is achieved.

[0046] Drive motor 18: Drive motor 18 is fixedly connected inside the protective cover 7. The output end of drive motor 18 is fixedly connected to gear 17. Drive motor 18 is the power source for rotating the fabric. It drives gear 17 to rotate through the output end, thereby driving rotating tube 15, conveying tube 16 and discharge tube 14 to rotate, providing continuous power for uniform fabric distribution.

[0047] Activated carbon filter plate 11: The activated carbon filter plate 11 is the core functional component for filtration and decolorization. It adsorbs pigments and impurities in the liquid to be filtered through activated carbon particles. The three stacked plates enhance the filtration effect. The fixed columns are connected as a whole for easy synchronous placement and removal. The mounting hole 19 is used in conjunction with the fixing screw 13 to achieve positioning and fixation.

[0048] Fixed columns: Multiple fixed columns are connected between the three activated carbon filter plates 11. The fixed columns connect the three independent activated carbon filter plates 11 into a whole structure, ensuring that the filter plates do not become misaligned during the loading, unloading or filtration process. At the same time, they are easy to lift and lower synchronously with the fixed screw 13, improving the plate replacement efficiency.

[0049] Mounting hole 19: Mounting hole 19 provides a through channel for fixing screw 13. The hole and screw work together to achieve precise positioning of activated carbon filter plate 11, ensuring that the filter plate is placed in the center of the conical filter tank 10 without shifting.

[0050] Fixed screws 13: The outer walls of the four fixed screws 13 are all fixedly fitted with circular limiting sleeves 12 and threaded with fixing nuts. The fixed screws 13 are the fixed carriers of the activated carbon filter plates 11. Through the cooperation of the circular limiting sleeves 12 and fixing nuts, the filter plates are locked on the screws to ensure that they do not shift due to liquid impact during the filtration process. At the same time, the filter plates can be removed and installed as the circular cover 8 rises and falls.

[0051] Circular limiting sleeve 12: The circular limiting sleeve 12 axially limits the activated carbon filter plate 11, determines the installation height of the filter plate on the fixing screw 13, prevents the filter plate from sliding downward under the action of gravity, and ensures that the gap between the filter plates and the tank wall is uniform.

[0052] Fixing nuts: Four fixing nuts are threaded onto the outer wall of the four fixing screws 13 respectively. The fixing nuts are locked by threads, which fixes the activated carbon filter plate 11 and the circular limiting sleeve 12 together on the fixing screws 13, which enhances the installation stability of the filter plate and prevents the filter plate from loosening due to vibration or liquid impact during the filtration process.

[0053] Cylinder 2: Two cylinders 2 are fixedly connected to opposite surfaces of two support plates 1 respectively. The telescopic ends of the two cylinders 2 are fixedly connected to connecting plates 3. Cylinder 2 is the power source for the lifting and lowering of the circular cover 8. By extending / contracting the telescopic ends, the connecting plates 3 and the circular cover 8 are driven to rise / fall along the outer wall of the conical filter tank 10, so as to realize the removal, replacement and reinstallation of the activated carbon filter plate 11.

[0054] Connecting plate 3: Two connecting plates 3 are fixedly connected to the telescopic ends of the two cylinders 2 respectively. The opposite surfaces of the two connecting plates 3 are fixedly connected to the circular cover 8. The connecting plate 3 is the connecting medium between the cylinder 2 and the circular cover 8, which transmits the telescopic power of the cylinder to the circular cover 8, ensuring that the circular cover is subjected to uniform force and that the lifting process is stable and does not tilt.

[0055] Furthermore, when using this activated carbon filtration and decolorization device, first connect the external feeding pipe to the external feeding connection pipe 5;

[0056] First, the drive motor 18 is started. After the drive motor 18 is started, the output end of the drive motor 18 drives the gear 17 to rotate. Since the two gears 17 mesh with each other, they drive the rotating tube 15 to rotate synchronously. The four conveying pipes 16 on the outer wall of the rotating tube 15 rotate with it. The multiple discharge pipes 14 on the lower surface of the conveying pipe 16 move in a circular motion synchronously. The external liquid to be filtered enters the connecting pipe 6 through the external feeding connecting pipe 5 and then flows into the rotating tube 15. Through the rotating conveying pipe 16 and discharge pipe 14, it is evenly sprayed onto the activated carbon filter plate 11 at the top of the conical filter tank 10, avoiding the liquid from only flowing through the activated carbon plate locally and greatly improving the utilization rate of the activated carbon filter plate 11.

[0057] In this process, after the liquid is initially filtered by the uppermost activated carbon filter plate 11, it permeates through the two lower activated carbon filter plates 11 in sequence. The activated carbon particles adsorb the pigments and impurities in the liquid, completing the decolorization filtration. The filtered liquid flows along the inner wall of the conical filter tank 10 to the discharge pipe on the lower surface and is finally discharged from the device, thus achieving continuous filtration operation.

[0058] When it is necessary to replace the activated carbon filter plate 11, first turn off the drive motor 18 and the external feed, start the two cylinders 2, the extension ends of the two cylinders 2 extend and drive the connecting plate 3 and the circular cover 8 to rise synchronously. The circular cover 8 slides along the outer wall of the conical filter tank 10, and the fixing screw 13 rises with the circular cover 8, driving the three activated carbon filter plates 11 to be pulled out from the conical filter tank 10. Then unscrew the fixing nuts on the outer wall of the four fixing screws 13, remove the circular limit sleeve 12, and the old activated carbon filter plate 11 can be removed from the fixing screw 13. When replacing the new activated carbon filter plate 11, align its mounting hole 19 with the fixing screw 13 and put it in, then install the circular limit sleeve 12 and the fixing nut in sequence and tighten them to complete the filter plate fixing.

[0059] After the filter plate is replaced, the cylinder 2 is started in reverse. Its telescopic end retracts, causing the circular cover 8 to descend until the lower surface of the circular cover 8 is in contact with the upper surface of the circular sleeve 9. The lower end of the fixing screw 13 re-enters the conical filter tank 10, and the device returns to the filtration state, which can continue to perform filtration and decolorization operations. The entire plate replacement process does not require disassembling the main body of the device. The filter plate can be quickly picked up and put down by lifting the cylinder 2, which solves the problem of difficult plate replacement in traditional devices.

[0060] The circular limiting sleeve 12 and the fixing nut work together to ensure that the three activated carbon filter plates 11 are in a stable position during the filtration process, preventing them from shifting due to liquid impact. The conical structure of the conical filter tank 10 facilitates liquid collection and discharge, reducing residue. The rotating connection design between the rotating tube 15 and the connecting tube 6 ensures smooth liquid transport without affecting the rotating material distribution of the rotating tube 15, further improving filtration uniformity and device operation stability.

[0061] The rotating material conveying assembly, through the rotation of the drive motor 18, gear 17, rotating tube 15, and conveying tube 16, solves the problem of localized liquid flow through the activated carbon plate, improving the utilization rate of the filter plate. The cylinder 2 drives the circular cover 8 to rise and fall, and the detachable design of the fixing screw 13 enables the rapid replacement of the activated carbon filter plate 11. Compared with traditional filtration devices, it not only ensures the filtration and decolorization effect, but also greatly improves the operating efficiency and practicality, and is suitable for batch liquid filtration and decolorization needs.

[0062] Example 1: Application of a large-diameter discharge pipe with an anti-stick coating to replace discharge pipe 14 in high-viscosity liquid filtration scenarios.

[0063] A food factory used this device to decolorize and filter high-viscosity syrup. The original discharge pipe 14 had a small aperture and no anti-sticking treatment, so the high-viscosity syrup easily adhered to the inner wall of the pipe, causing the discharge pipe to become blocked and requiring frequent shutdowns for unblocking. At the same time, the viscous liquid had a limited diffusion range after being sprayed out of the small holes. Even with rotating the cloth, there was still a problem of insufficient coverage of the filter plate in some areas, which affected the uniformity of decolorization. At this time, the original discharge pipe 14 was replaced with a large-diameter discharge pipe with a PTFE anti-stick coating. The aperture was enlarged and an inclined guide groove was added to the pipe opening. The coating thickness was adapted to the viscous environment of the syrup.

[0064] Improved adaptability to high-viscosity liquid flow: The anti-stick coating reduces the adhesion of syrup to the inner wall of the discharge pipe, avoiding blockage caused by residue accumulation, eliminating the need for frequent shutdowns for unblocking; The large-diameter design reduces liquid flow resistance, and together with the inclined guide channel, it allows viscous syrup to be sprayed out smoothly and spread quickly. Compared with the original discharge pipe 14, the material coverage is wider, and the filter plate is evenly stressed throughout, avoiding local adsorption saturation;

[0065] Uniform coverage ensures that the adsorption capacity of the activated carbon filter plate 11 is fully utilized, improves the uniformity of syrup decolorization, and avoids local pigment residue; the non-stick coating reduces material waste and leaves no residual pollution, ensuring the hygiene and safety of food-grade products and meeting the filtration needs of high-viscosity food raw materials.

[0066] The installation dimensions of the new discharge pipe are the same as those of the original discharge pipe 14. It can be directly fixed on the conveying pipe 16 without modifying the rotating pipe 15 or the conveying pipe structure. It works smoothly with the rotating fabric driven by the drive motor 18, without affecting the original rotation speed and fabric rhythm, and without additional modification costs.

[0067] Example 2: Application of ceramic membrane composite filter plate replacing intermediate activated carbon filter plate 11 in high-precision filtration scenarios

[0068] A pharmaceutical company needs to perform high-precision decolorization filtration on its liquid medicine. This requires not only removing pigments but also intercepting minute impurities (particle size ≤ 1μm). The original three-layer activated carbon filter plate 11, made of a single activated carbon material, is insufficient to intercept these minute impurities, leaving trace impurities in the filtered liquid. Furthermore, the middle activated carbon layer is prone to rapid clogging due to impurity accumulation, shortening the replacement cycle. Therefore, the middle activated carbon filter plate 11 is replaced with a ceramic membrane composite plate, while retaining the upper and lower activated carbon layers, forming an activated carbon-ceramic membrane-activated carbon composite filtration structure. The ceramic membrane's pore size is tailored to the requirements for intercepting minute impurities.

[0069] The microporous structure of the ceramic membrane composite plate can precisely intercept tiny impurities. Combined with the adsorption effect of the upper and lower activated carbon plates, it can not only decolorize pigments but also remove trace impurities, significantly improving the purity of the medicine solution. Compared with the original single activated carbon filtration, impurities are removed more thoroughly, making it suitable for the high-precision filtration standards of the pharmaceutical industry.

[0070] The ceramic membrane has strong anti-clogging ability, and the middle layer is not easy to fail due to the accumulation of impurities. The overall replacement cycle of the three-layer composite structure is longer than that of the original activated carbon filter plate 11. Moreover, the mounting holes 19 of the composite plate are the same as those of the original filter plate, and it can be directly fixed by the fixing screw 13. This maintains the rapid replacement process of the cylinder 2 driving the circular cover 8 to rise and fall without increasing the complexity of operation.

[0071] The upper and lower activated carbon plates are responsible for adsorbing pigments and odors, while the middle ceramic membrane focuses on intercepting impurities. Their division of labor and cooperation improve the overall filtration effect. The rigid structure of the ceramic membrane does not affect the liquid permeation rate. Together with the uniform distribution of the rotating conveyor components, it ensures that the medicine is evenly distributed on the surface of the composite filter layer, with no dead corners in the filtration, and ensures that the quality of each batch of medicine is consistent.

[0072] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
