Description

Technical Field

[0001] This application relates to the field of decolorization and recycling technology, and in particular to a decolorization component, a decolorization tank, and a decolorization device. Background Technology

[0002] In the process of recovering pore-forming agents, the main equipment in the decolorization step is the decolorization tank. Typically, the decolorization tank is a single-stage adsorption tank. The material enters the tank through the inlet, is decolorized by activated carbon, and then exits through the outlet. While this single-stage adsorption decolorization tank can basically achieve the decolorization function, it still suffers from problems such as uneven contact between activated carbon and material leading to poor decolorization effect and low production efficiency.

[0011] In some embodiments of the first aspect, the container has a centerline that is parallel to a predetermined axis.

[0012] The inner cavity includes an inlet cavity and a filter cavity, which are arranged sequentially in a direction away from the center line. Both the inlet cavity and the filter cavity extend around the center line. The inlet cavity is connected to the feed inlet, and the side of the filter cavity away from the center line is connected to the discharge outlet. The filter cavity is provided with the decolorization adsorption section, and the side wall connecting the inlet cavity and the filter cavity is provided with multiple water distribution holes, which connect the inlet cavity and the filter cavity.

[0013] In some embodiments of the first aspect, the inner cavity further includes a drainage cavity located outside the filter cavity, the drainage cavity extending circumferentially along the filter cavity, the discharge port communicating with the drainage cavity, and the bottom of the drainage cavity having a drainage outlet;

[0014] The number of the inner cavities is at least two, and all the inner cavities are arranged sequentially in a direction away from the center line.

[0015] In some embodiments of the first aspect, the feeder further includes a rotary joint, the outlet of which is connected to the inlet of the second feed tube, and the inlet of which is connected to the outlet of the first feed tube.

[0016] In some embodiments of the first aspect, the drive includes:

[0017] A drive motor has a main shaft, the axis of the main shaft is collinear with the preset axis, and a feeding channel is axially provided through the main shaft. The main shaft is connected to the container.

[0018] One end of the feeding channel is connected to the inlet end of the second feeding pipe, and the other end of the feeding channel is connected to the outlet end of the rotary joint.

[0019] In some embodiments of the first aspect, the decolorizing adsorption unit includes a filter bag filled with decolorizing adsorption particles; wherein the mesh size of the filter bag is M, and satisfies: 0.5um ≤ M ≤ 1um.

[0020] In some embodiments of the first aspect, the feed inlet is located inside the filter bag.

[0021] Secondly, embodiments of this application also provide a decolorizing tank, the decolorizing tank including a tank body and a decolorizing component as described in any of the above embodiments, wherein the container of the decolorizing component is located inside the tank body.

[0022] Thirdly, embodiments of this application also provide a decolorizing apparatus, the decolorizing apparatus comprising:

[0023] Storage tank, the storage tank being used to store materials;

[0024] A first pumping component, the inlet of which is connected to the outlet of the storage tank, is used to pump out materials.

[0025] A filter, the inlet of which is connected to the outlet of the first extraction component, is used to filter materials;

[0028] As described in the above embodiments, the decolorizing tank has its first feed pipe inlet end connected to the inlet of the second extraction component.

[0029] The embodiments of this application have the following advantages:

[0030] This application provides a decolorization assembly. Material enters the inlet of a container through a rotary-sealed connection of feeding components (a first feeding pipe and a second feeding pipe), flowing into the inner cavity. A decolorization adsorption section (such as an activated carbon layer) is provided within the inner cavity. Its microporous structure allows pigments to be adsorbed upon material penetration, and the material is subsequently discharged from multiple outlets. The outlets are distributed on the outer wall of the container away from the axis, facilitating uniform discharge under centrifugal force. A driving component drives the container to rotate around a preset axis, causing relative motion between the decolorization adsorption section and the material within the inner cavity. The centrifugal force generated by the rotation forces the material through the microporous structure of the decolorization adsorption section, enhancing the uniformity of contact between the activated carbon and the material and avoiding the localized saturation problem of static adsorption. The multiple outlets are distributed dispersedly, and combined with the rotational action, create a multidirectional flow path for the material within the decolorization adsorption section, extending the contact time and improving decolorization efficiency.

[0031] Therefore, the centrifugal force generated by rotation forces the material to fully penetrate the micropores of the decolorization adsorption section, improving the utilization rate of activated carbon and achieving more thorough pigment adsorption. This solves the problem of poor decolorization effect caused by uneven contact in traditional single-stage tanks. The dynamic adsorption process shortens the decolorization time, and the multi-outlet design accelerates material discharge, resulting in an overall processing efficiency higher than that of static single-stage decolorization tanks.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] In related technologies, the main equipment for the decolorization process in the recovery of pore-forming agents is the decolorization tank. Typically, the decolorization tank is a single-stage adsorption tank. The material enters the tank through the inlet, is decolorized by activated carbon, and then exits through the outlet. While this type of decolorization tank with only single-stage adsorption can basically achieve the decolorization function, it still suffers from problems such as uneven contact between activated carbon and material leading to poor decolorization effect and low production efficiency.

[0048] As shown in Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, in order to solve the above-mentioned technical problems, this application provides a decolorizing component. The decolorizing component has a preset axis and includes a container 130, a driving component, and a feeding component. The container 130 has a feeding port 131, multiple discharging ports 136, and an inner cavity. The multiple discharging ports 136 are at least partially distributed on the outer wall of the container 130 away from the preset axis, and all the discharging ports 136 are connected to the inner cavity. The feeding port 131 is connected to the inner cavity. A decolorizing adsorption section is provided in the inner cavity. The decolorizing adsorption section forms a microporous structure. The feeding port 131 is connected to the discharging ports 136 through the microporous structure. The decolorizing adsorption section is used to adsorb pigments.

[0049] The driving component is connected to the container component 130, and the driving component can drive the container component 130 to rotate around a preset axis.

[0050] The feeding component includes a first feeding pipe 160 and a second feeding pipe 120. The axis of the inlet end of the second feeding pipe 120 is collinear with a preset axis. The outlet end of the first feeding pipe 160 and the inlet end of the second feeding pipe 120 are rotatably sealed together, so that the first feeding pipe 160 and the second feeding pipe 120 are connected in a continuous manner, and the outlet end 121 of the second feeding pipe is connected in a continuous manner with the feed port 131.

[0051] These embodiments aim to improve the decolorization effect and production efficiency of materials. The container 130 is the core container for the decolorization process, having an inlet 131, multiple outlets 136, and an inner cavity. The outlets 136 are distributed on the outer wall of the container 130, at least partially located away from a predetermined axis, and communicate with the inner cavity. An internal decolorization adsorption section with a microporous structure is provided for adsorbing pigments, ensuring that the material entering from the inlet 131 can flow through these microporous structures to the various outlets 136.

[0052] For example, in this embodiment, multiple discharge ports 136 are evenly distributed on the outer wall of the container 130. Of course, in other embodiments, they may only be located on the outer wall of the container 130 at a position opposite to a predetermined axis.

[0053] For example, the decolorization adsorption section is formed by filling the inner cavity with decolorization adsorption particles, which may be activated carbon, activated alumina, polymer adsorbents, etc.

[0054] The driving component is connected to the container 130 and can drive the container 130 to rotate around a preset axis. The centrifugal force generated by this rotation mechanism helps to increase the uniformity of contact between the material and the decolorizing adsorbent, thereby improving the decolorization efficiency and effect. Furthermore, the centrifugal force also facilitates the rapid passage of material, improving work efficiency.

[0055] For example, the drive unit can be an electric motor, a pneumatic motor, or a hydraulic motor, etc.

[0056] The feeding component consists of a first feed pipe 160 and a second feed pipe 120. The axis of the inlet end of the second feed pipe 120 is collinear with a preset axis and is connected by a rotary seal. This ensures that the material can enter the container 130 during its rotation and prevents leakage.

[0057] In other words, the material enters the inlet 131 of the container 130 through the rotary sealing connection of the feeding components (first feed pipe 160 and second feed pipe 120) and flows into the inner cavity. A decolorizing adsorption section (such as an activated carbon layer) is provided in the inner cavity. Its microporous structure allows the material to adsorb pigments upon penetration, and it is then discharged from multiple outlets 136. The outlets 136 are distributed on the outer wall of the container 130 away from the axis, facilitating uniform discharge under centrifugal force. The driving component drives the container 130 to rotate around a preset axis, causing relative motion between the decolorizing adsorption section and the material in the inner cavity. The centrifugal force generated by the rotation forces the material through the microporous structure of the decolorizing adsorption section, enhancing the uniformity of contact between the activated carbon and the material and avoiding the local saturation problem of static adsorption. The multiple outlets 136 are distributed and, combined with the rotation, create a multi-directional flow path for the material in the decolorizing adsorption section, extending the contact time and improving decolorization efficiency.

[0058] Therefore, the centrifugal force generated by rotation forces the material to fully penetrate the micropores of the decolorization adsorption section, improving the utilization rate of activated carbon and achieving more thorough pigment adsorption. This solves the problem of poor decolorization effect caused by uneven contact in traditional single-stage tanks 110. The dynamic adsorption process shortens the decolorization time, and the multi-outlet design 136 accelerates material discharge, resulting in an overall processing efficiency higher than that of static single-stage decolorization tanks 100.

[0059] like Figure 2 As shown, in some embodiments, there are multiple container components 130, and the drive component is connected to all container components 130;

[0060] The second feed pipe 120 has multiple outlet ends. The outlet end 121 of the second feed pipe has a preset extension direction, which is intersected with a preset axis. Each outlet end of the second feed pipe 120 is connected to at least two container components 130. The at least two container components 130 are spaced apart along the preset extension direction. The feed port 131 of each container component 130 is connected to the corresponding outlet end 121 of the second feed pipe.

[0061] In these embodiments, overall processing capacity and efficiency are improved by increasing the number of container units 130 and optimizing the layout of the feed pipes. In this embodiment, there are multiple container units 130, and all container units 130 are connected to a single drive unit. Multiple decolorization units can be operated simultaneously by a single drive system, thereby achieving higher processing capacity.

[0062] The second feed pipe 120 has multiple outlet ends, each with a preset extension direction, meaning the outlet end extends along a preset extension direction, and these preset extension directions intersect a preset axis. This design allows for more uniform distribution of material into each container 130. For example, in this embodiment, the preset extension direction and the preset axis are perpendicular. Of course, in other embodiments, the angle between the preset extension direction and the preset axis is 30°, 40°, 50°, or 60°, etc.

[0063] Each outlet is connected to at least two containers 130, which are spaced apart along a predetermined extension direction. This approach helps to improve the modularity of the system, facilitating maintenance and expansion. The inlet 131 of each container 130 is connected to the outlet 121 of the corresponding second feed pipe, ensuring that the material can smoothly enter each container 130 for decolorization treatment.

[0064] For example, in this embodiment, two container components 130 are provided on each outlet end. Of course, in other embodiments, the number of container components 130 provided on each outlet end may be three, four, five, etc. In actual installation, the drive component and the mounting frame are connected, and all the container components 130 are disposed on the mounting frame, so that the drive component drives the mounting frame to rotate, thereby driving all the container components 130 to rotate.

[0065] Clearly, by increasing the number of container 130, the processing capacity can be significantly increased without significantly increasing the floor space, making it suitable for scenarios requiring large-scale decolorization operations.

[0066] It should be noted that the extended outlet end of the second feed pipe 120 allows the material to be more evenly distributed among the containers 130 under centrifugal force, avoiding overloading of some containers while underutilizing others, thus improving the overall system balance and efficiency. In other words, the centrifugal force on the material gradually increases at the outlet end of the second feed pipe 120 in the direction away from the preset axis, thereby facilitating a more even distribution of the material among the multiple containers 130 at the same outlet end.

[0067] like Figure 2 As shown, in some embodiments, the container 130 has a centerline, which is arranged parallel to a preset axis.

[0068] The inner cavity includes an inlet chamber 132 and a filter chamber 133, which are arranged sequentially in a direction away from the center line. Both the inlet chamber 132 and the filter chamber 133 extend around the center line. The inlet chamber 132 is connected to the feed inlet 131. The side of the filter chamber 133 away from the center line is connected to the discharge outlet 136. The filter chamber 133 is provided with a decolorization adsorption section, and the side wall connecting the inlet chamber 132 and the filter chamber 133 is provided with multiple water distribution holes 134, which connect the inlet chamber 132 and the filter chamber 133.

[0069] In these embodiments, the internal structure of the container 130 is further refined by differentiating different chambers to optimize material flow paths and decolorization efficiency.

[0070] The centerline is parallel to the preset axis: The container 130 has a centerline that is parallel to the preset axis of the entire decolorization assembly, in order to define the position of the discharge port 136.

[0071] The liquid inlet chamber 132 is located on the side near the center line and is directly connected to the feed inlet 131. The main function of the liquid inlet chamber 132 is to receive the material to be processed from the feed inlet 131 and distribute the material evenly into the filter chamber 133 through multiple water distribution holes 134 on its inner wall.

[0072] The filter chamber 133 is located outside the liquid inlet chamber 132, extends in a direction away from the center line, and communicates with the discharge port 136. The filter chamber 133 is provided with a decolorizing adsorption section (such as an activated carbon layer) for adsorbing pigment components in the material.

[0073] The inner wall of the liquid inlet chamber 132 has multiple water distribution holes 134, one end of which is connected to the liquid inlet chamber 132 and the other end is connected to the filter chamber 133. This ensures that the material is evenly dispersed before entering the filter chamber 133, thereby improving the effect of the subsequent decolorization process.

[0074] In some embodiments, the inner cavity further includes a drain cavity 135, which is located outside the filter cavity 133. The drain cavity 135 extends circumferentially along the filter cavity 133. The discharge port 136 communicates with the drain cavity 135, and the bottom of the drain cavity 135 has a drain outlet. The number of inner cavities is at least two, and all inner cavities are arranged sequentially in a direction away from the center line.

[0075] In these embodiments, the internal cavity structure of the container 130 becomes more complex and the functional zoning is more clearly defined. This design optimizes the liquid flow path by adding a drainage chamber 135, while allowing for the existence of multiple cavities to improve handling capacity and efficiency.

[0076] The drain chamber 135 is located outside the filter chamber 133 and extends circumferentially along the filter chamber 133. This arrangement facilitates the collection of liquid after treatment by the decolorization adsorption section.

[0077] All discharge ports 136 are directly connected to the drainage chamber 135 to ensure that the treated liquid can be discharged smoothly. In addition, the drainage chamber 135 is provided with a drainage port at the bottom for finally discharging the treated liquid out of the container 130.

[0078] Furthermore, there are at least two inner cavities, and all the inner cavities are arranged sequentially in a direction away from the center line. This means that the liquid first enters the inlet cavity 132, then enters the filter cavity 133 for decolorization, and finally enters the outlet cavity 135 to be discharged.

[0079] The design of multiple cavities not only increases the system's processing capacity but also allows for simultaneous processing steps in different cavities, thereby improving the overall decolorization effect.

[0080] For example, in this embodiment, the number of cavities is one. Of course, in other embodiments, the number of cavities may be two, three, or four, etc.

[0081] In some embodiments, the feeder also includes a rotary joint 150, the outlet of which is connected to the inlet of the second feed pipe 120, and the inlet of the rotary joint 150 is connected to the outlet of the first feed pipe 160.

[0082] In these embodiments, the addition of the rotary joint 150 allows the first feed pipe 160 and the second feed pipe 120 to allow one or both pipes to rotate while maintaining a seal, which enables continuous feeding and ensures the stability and reliability of the equipment during operation.

[0083] The rotary joint 150 is a key component connecting the first feed pipe 160 and the second feed pipe 120. It allows the two pipe sections to maintain a sealed connection even when they rotate relative to each other.

[0084] One end (inlet) of the rotary joint 150 is connected to the outlet end of the first feed pipe 160, and the other end (outlet) is connected to the inlet end of the second feed pipe 120. This design ensures that material can smoothly enter the rotating internal pipe (second feed pipe 120) from the fixed external pipe (first feed pipe 160) without causing leakage.

[0085] The rotary joint 150 solves the sealing problem between the rotating and stationary components, enabling the entire system to complete complex mechanical movements without affecting material conveying. This is particularly important for decolorization devices that require continuous feeding and involve rotational operation.

[0086] By using the rotary joint 150, the feed path and the layout of the container 130 can be arranged more flexibly, increasing the freedom of system design. Furthermore, this also facilitates the adjustment of feed rate and pressure to adapt to different processing requirements.

[0087] like Figure 1 As shown, in some embodiments, the driving component includes a drive motor 140, which has a main shaft. The axis of the main shaft is collinear with a preset axis, and a feed channel is axially provided through the main shaft. The main shaft is connected to the container 130.

[0088] One end of the feeding channel is connected to the inlet end of the second feeding pipe 120, and the other end of the feeding channel is connected to the outlet end of the rotary joint 150.

[0089] In these embodiments, an integrated design of material handling and mechanical drive is achieved by using a drive motor 140 spindle with a central feed channel.

[0090] The drive motor 140 serves as the power source, providing rotational power to enable the container 130 to rotate around a preset axis. The drive motor 140 is equipped with a main shaft whose axis is collinear with the preset axis of the entire decolorization assembly, ensuring the smoothness and symmetry of the rotational motion. It should be noted that, as is standard practice, the drive motor 140's housing is fixedly mounted, such as on a motor bracket or motor base, simply to maintain the rotation of the main shaft.

[0091] For example, in this embodiment, the main shaft of the drive motor 140 and the second feed pipe 120 are coaxially and fixedly connected, and the feed channel in the main shaft is kept in communication with the rotary joint 150 and the second feed pipe 120 respectively. Of course, in other embodiments, the main shaft and the rotating shaft are drivenly connected, and the feed channel is set on the rotating shaft, so that the feed channel is axially connected with the rotary joint 150 and the second feed pipe 120 respectively.

[0092] In particular, the main shaft has a feed channel that runs through it axially, allowing the material transport path to pass directly through the drive unit, thereby simplifying the overall structure and improving compactness.

[0093] Clearly, the feed channel on the main shaft, in conjunction with the rotary joint 150, allows the main shaft to not only transmit rotational power but also serve as a channel for material to enter the container 130. One end of the feed channel connects to the inlet end of the second feed pipe 120, and the other end connects to the outlet end of the rotary joint 150. In this way, material can pass through a fixed external pipe (first feed pipe 160), through the rotary joint 150 and the feed channel inside the main shaft, and finally reach the rotating second feed pipe 120, from where it is distributed to the various containers 130 for processing.

[0094] Therefore, integrating the drive function and material conveying path reduces the number of independent components, simplifies the system structure, lowers maintenance costs, and improves the overall reliability of the equipment.

[0095] In some embodiments, the decolorization adsorption unit includes a filter bag filled with decolorization adsorption particles; wherein the mesh size of the filter bag is M, and satisfies: 0.5um≤M≤1um.

[0096] In these embodiments, the presence of filter bags allows the decolorizing adsorbed particles to work in a fixed area, avoiding problems such as particle loss or uneven distribution.

[0097] The mesh size of the filter bags is limited to 0.5um ≤ M ≤ 1um, ensuring that the filter bags can effectively intercept fine pigment molecules without significantly increasing flow resistance. This design makes the decolorization process more efficient and thorough.

[0098] Using filter bags as carriers for decolorizing adsorbent particles effectively prevents particle leakage into the material, avoiding contamination of the final product and reducing the need for subsequent filtration steps. Since the decolorizing adsorbent particles are contained within the filter bag, excess pore-forming agent adsorbed by the particles overflows downwards. The overflow speed is accelerated by the drive motor 140, theoretically shortening the time. However, the adsorbed sand is contained within the filter bag, and due to the mesh size, it may not be completely ejected during motor rotation. Some sand may not be completely ejected due to the resistance of the filter bag and will continue to overflow downwards under gravity until the filter bag is saturated with adsorbed sand. Using filter bags compensates for the short time required to eject the pore-forming agent; the overflow speed is faster, but the amount ejected is less, achieving the same decolorization effect.

[0099] In some embodiments, the feed inlet 131 is located inside the filter bag.

[0100] In these embodiments, the feed inlet 131 extends into the filter bag, so the pore-forming agent comes into contact with the decolorizing adsorbent particles as it flows out, preventing it from being directly thrown out. Simultaneously, after the decolorizing adsorbent particles become saturated, the excess pore-forming agent overflows downwards under the action of the drive motor 140 until all the adsorbent sand at the bottom is saturated, facilitating the even distribution of the pore-forming agent.

[0101] like Figure 1 and Figure 2 As shown, in some embodiments, this application also provides a decolorizing tank 100, which includes a tank body 110 and a decolorizing component as described in any of the above embodiments, wherein the container 130 of the decolorizing component is located inside the tank body 110.

[0102] In some embodiments, the decolorization tank 100 has an openable side to facilitate the replacement of the filter bag in the decolorization assembly.

[0103] Obviously, the material filtered and decolorized by container 130 will fall directly into tank 110 for storage. Since the decolorization component has the aforementioned technical effects, the decolorization tank 100, which includes the decolorization component, should have the same technical effects, which will not be elaborated here.

[0104] like Figure 5 As shown, in some embodiments, this application also provides a decolorization device, which includes a storage tank 200, a first extraction component 300, a filter 400, a preheating tank 500, a second extraction component 600, and a decolorization tank 100. The storage tank 200 is used to store materials; the inlet of the first extraction component 300 is connected to the outlet of the storage tank 200, and the first extraction component 300 is used to extract materials; the inlet of the filter 400 is connected to the outlet of the first extraction component 300, and the filter 400 is used to filter materials; the inlet of the preheating tank 500 is connected to the outlet of the filter 400, and the preheating tank 500 is used to store and heat materials; the inlet of the second extraction component 600 is connected to the outlet of the preheating tank 500, and the first extraction component 300 is used to extract materials; the inlet end of the first feed pipe 160 of the decolorization tank 100 is connected to the inlet of the second extraction component 600.

[0105] These embodiments provide a complete decolorization apparatus system, including all stages from material storage to final decolorization treatment. The following are the specific components and functional descriptions of this decolorization apparatus:

[0106] Storage tank 200 is used to store materials to be processed. As the starting point of the entire processing flow, it ensures that there is sufficient material to supply subsequent processing steps.

[0107] The inlet of the first extraction unit 300 is connected to the outlet of the storage tank 200. It is responsible for extracting material from the storage tank 200 and conveying it to the next processing unit, namely, to the filter 400. It provides the power for material flow, ensuring that the material can smoothly enter the filter 400 for preliminary purification.

[0108] The inlet of filter 400 is connected to the outlet of the first extraction component 300. It performs preliminary filtration of the material, removing large particulate impurities and other suspended solids. This protects downstream equipment from damage by larger particles and reduces unnecessary contamination.

[0109] The inlet of the preheating tank 500 is connected to the outlet of the filter 400. It is used to store the filtered material and heat it. Appropriate temperature can improve the efficiency and effectiveness of subsequent decolorization processes. Furthermore, the purpose of heating is to reduce moisture in the pore-forming agent, which can cause defective oil stains during production.

[0110] The inlet of the second extraction unit 600 is connected to the outlet of the preheating tank 500. It is responsible for extracting the preheated material and conveying it to the decolorizing tank 100. This ensures that the material enters the decolorization stage in optimal condition, maximizing decolorization efficiency.

[0111] The feed end of the first feed pipe 160 of the decolorizing tank 100 is connected to the outlet of the second extraction component 600. The main decolorization operation is performed, removing pigments from the material through an internal decolorizing adsorption unit (e.g., decolorizing adsorption granules filled in a filter bag). This achieves efficient and thorough decolorization, preparing the material for the next stage of production or direct use.

[0112] Therefore, the entire process, from material storage, extraction, filtration, preheating to final decolorization, is rationally designed with each step closely linked, ensuring the continuity and stability of the process. The filtration and preheating steps remove impurities from the material and adjust it to a suitable temperature, providing favorable conditions for subsequent decolorization and contributing to improved quality of the final product.

[0113] Furthermore, since the decolorizing tank 100 has the aforementioned technical effects, the decolorizing device including the decolorizing tank 100 should have the same technical effects, which will not be elaborated here.

[0114] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0115] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0116] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
