Description

Technical Field

[0001] This utility model relates to the field of decolorization kettle technology, specifically to an activated carbon rapid decolorization kettle. Background Technology

[0002] The activated carbon rapid decolorization kettle is a specialized device for decolorizing materials, widely used in food processing, chemical, and pharmaceutical industries, and plays a particularly important role in processes requiring the adsorption of impurities by activated carbon. Its main function is to remove impurities and pigments from liquids through thorough mixing of activated carbon and liquid materials, utilizing both physical and chemical adsorption principles, thereby improving product purity and quality. Compared to traditional decolorization equipment, the activated carbon rapid decolorization kettle offers significant advantages in mixing efficiency, decolorization effect, and ease of discharge, while also being adaptable to different materials and process requirements, meeting the stringent requirements of industrial production.

[0003] Patent CN222238899U discloses a decolorizing reactor for easy discharge, including a heating tank and a cover plate covering the heating tank. It also includes: a driving unit disposed on the outer wall of the heating tank and used to drive the cover plate to move longitudinally; a rotating shaft rotatably connected inside the heating tank and vertically connected to the cover plate; and multiple sets of levers fixedly connected at equal intervals to the rotating shaft. This invention improves the mixing and decolorization effect of the liquid by agitating and mixing activated carbon and liquid in multiple ways. Furthermore, by pressurizing the heating tank, it not only disturbs the activated carbon to move better in the liquid, further improving the mixing and decolorization effect, but also helps the liquid to be quickly discharged from the heating tank through the discharge pipe after decolorization, thus improving discharge efficiency.

[0004] The existing technology described above uses various methods to agitate and mix activated carbon and liquid to improve the mixing and decolorization effect of the liquid. The filter plate can block the activated carbon, preventing it from being discharged from the discharge pipe along with the liquid. When the liquid is completely discharged from the heating tank, the cover plate is driven upward by an electric telescopic rod, moving it away from the heating tank and opening it. At the same time, the cover plate drives the filter plate upward through a rotating shaft until it is removed from the heating tank, making it easier for workers to clean the activated carbon blocked on the filter plate. However, when removing the activated carbon from the filter plate, since the filter plate cannot be disassembled, workers cannot quickly clean the used activated carbon, affecting work efficiency. In view of this, we propose an activated carbon rapid decolorization kettle. Utility Model Content

[0005] The purpose of this invention is to provide a rapid activated carbon decolorization kettle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid activated carbon decolorization kettle includes a decolorization kettle body for containing liquid and activated carbon, serving as the main reaction space for the decolorization process. An electric heater is installed on the outer wall of the decolorization kettle body, connected to an external power supply and a temperature controller, to heat the liquid material inside the decolorization kettle body, providing a suitable temperature to enhance the adsorption effect of the activated carbon. The decolorization kettle body has an inner barrel with open top and bottom for loading activated carbon. Multiple rectangular openings arranged in a circular array are provided on the outer wall of the inner barrel for liquid flow and to facilitate uniform stirring. Filter screens are installed inside the rectangular openings to block activated carbon particles and prevent them from flowing out with the liquid.

[0008] The top flange of the decolorizing kettle is connected to a top cover. A feed pipe is provided at the top and near the middle of the top cover. The feed pipe is located above the inner barrel and is used to add liquid materials into the decolorizing kettle and activated carbon into the inner barrel. A lifting component is provided at the top of the top cover to drive the stirring component and the conical bottom plate to move up and down. After decolorization is completed, the lifting component drives the stirring component and the conical bottom plate to move down, so that the conical bottom plate separates from the inner barrel, thereby causing the activated carbon in the inner barrel to fall down and be discharged from the discharge pipe, thus achieving the function of quickly discharging liquid and activated carbon.

[0009] The lifting assembly includes a U-shaped fixing plate fixedly connected to the top of the top cover to support the entire lifting system. A lead screw is rotatably connected between the upper and lower sides of the inner wall of the U-shaped fixing plate to drive the movable plate to move up and down by rotation. The top of the U-shaped fixing plate is provided with a first motor for driving the lead screw to rotate. The first motor drives the lead screw to rotate forward and backward, thereby realizing the lifting of the movable plate and the stirring component. The outer wall of the lead screw is threadedly connected to the movable plate. The lifting of the movable plate directly drives the stirring component and the conical base plate to move.

[0010] The movable plate is equipped with a stirring element for thoroughly mixing the liquid and activated carbon. The stirring element includes a second motor mounted on the top of the movable plate to drive the stirring rod to rotate. The output shaft of the second motor passes through the top of the movable plate and is coaxially connected to the stirring rod. The bottom end of the stirring rod passes through the top of the top cover and extends into the inner tank. The outer wall of the stirring rod is equipped with multiple stirring blades for dispersing the activated carbon and uniformly mixing the liquid. The bottom end of the stirring rod is rotatably connected to a conical base plate. The bottom of the decolorizing kettle is equipped with a discharge pipe with a valve. The discharge pipe first discharges the decolorized liquid and then discharges the used activated carbon, eliminating the need to disassemble the inner tank and effectively improving the replacement efficiency of the activated carbon.

[0011] Preferably, the inner wall of the decolorizing vessel is provided with an annular support plate near the top to fix the inner barrel and prevent it from shaking. The outer wall of the inner barrel is provided with an annular hanging plate near the top, and the bottom of the annular hanging plate abuts against the top of the annular support plate to stabilize the position of the inner barrel.

[0012] Preferably, the top of the annular support plate is provided with multiple positioning holes, and the bottom of the annular hanging plate is provided with multiple positioning posts arranged in a circular array. The bottom ends of the multiple positioning posts pass through the multiple positioning holes respectively, thereby realizing the positioning and installation of the inner tub.

[0013] Preferably, the feed pipe is equipped with a control valve, and the top of the feed pipe is fitted with a pipe cap. After adding the solution and activated carbon, the pipe cap is fitted onto the top of the feed pipe to prevent dust from entering the feed pipe.

[0014] Preferably, a positioning vertical rod is provided between the upper and lower sides of the inner wall of the U-shaped fixed plate, and the movable plate is slidably connected to the outside of the positioning vertical rod to limit the movement direction of the movable plate and ensure its stability during lifting.

[0015] Preferably, when the movable plate rises to its highest point, the outer edge of the top of the conical base plate is in contact with the bottom of the inner barrel. At this time, the activated carbon is confined inside the inner barrel, ensuring the smooth progress of the decolorization process.

[0016] Preferably, when the movable plate descends to its lowest point, the outer edge of the top of the conical base plate is 4-8 cm away from the bottom of the inner barrel. At this time, the activated carbon can fall smoothly from the inner barrel down to the discharge pipe, achieving rapid discharge.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This activated carbon rapid decolorization kettle, through the combination structure of the inner barrel and filter screen, makes the separation of activated carbon and liquid more efficient and avoids the situation where activated carbon particles are discharged with the liquid. This design can ensure the purity of the discharged liquid and reduce the complexity of subsequent filtration treatment.

[0019] 2. The design of this activated carbon rapid decolorization kettle, with its lifting component, allows the stirring element and conical bottom plate to move up and down. This not only enables thorough mixing of the liquid and activated carbon, but also allows for rapid release of activated carbon during discharge by lowering the bottom plate, thus improving the efficiency of activated carbon replacement and solving the problem of traditional filter discs being unable to quickly clean activated carbon.

[0020] 3. This activated carbon rapid decolorization kettle can quickly discharge activated carbon after decolorization by controlling the lifting component, eliminating the need to manually clean the activated carbon on the filter plate, thereby reducing manual labor and improving the automation level and production efficiency of the equipment.

[0029] Please see Figures 1-5 This utility model provides a technical solution:

[0030] A rapid decolorization kettle for activated carbon includes a decolorization kettle body 1 for containing liquid and activated carbon, serving as the main reaction space for the decolorization process. An electric heater 2 is provided on the outer wall of the decolorization kettle body 1. The electric heater 2 is connected to an external power supply and a temperature controller to heat the liquid material in the decolorization kettle body 1, providing a suitable temperature to improve the adsorption effect of activated carbon. The decolorization kettle body 1 has an inner barrel 7 with an open structure at the top and bottom for loading activated carbon. The outer wall of the inner barrel 7 has multiple rectangular openings 70 arranged in a ring array for liquid flow and to facilitate uniform stirring. A filter screen 73 is provided in the rectangular openings 70 to block activated carbon particles and prevent them from flowing out with the liquid.

[0031] The top flange of the decolorizing kettle body 1 is connected to the top cover 3. The top of the top cover 3 and near the middle is provided with a feed pipe 30. The feed pipe 30 is located above the inner barrel 7 and is used to add liquid materials into the decolorizing kettle body 1 and to add activated carbon into the inner barrel 7. The top of the top cover 3 is provided with a lifting component 4, which is used to drive the stirring component 5 and the conical bottom plate 6 to move up and down. When the decolorization is completed, the lifting component 4 drives the stirring component 5 and the conical bottom plate 6 to move down, so that the conical bottom plate 6 and the inner barrel 7 are separated, thereby causing the activated carbon in the inner barrel 7 to fall down and be discharged from the discharge pipe 10, thus achieving the function of quickly discharging liquid and activated carbon.

[0032] The lifting assembly 4 includes a U-shaped fixing plate 40 fixedly connected to the top of the top cover 3 to support the entire lifting system. A lead screw 41 is rotatably connected between the upper and lower sides of the inner wall of the U-shaped fixing plate 40 to drive the movable plate 43 to move up and down by rotation. The top of the U-shaped fixing plate 40 is provided with a first motor 42 for driving the lead screw 41 to rotate. The first motor 42 drives the lead screw 41 to rotate forward and backward, thereby realizing the lifting of the movable plate 43 and the stirring component 5. The outer wall of the lead screw 41 is threadedly connected to the movable plate 43. The lifting of the movable plate 43 directly drives the stirring component 5 and the conical base plate 6 to move.

[0033] The movable plate 43 is equipped with a stirring element 5 for thoroughly mixing the liquid and activated carbon. The stirring element 5 includes a second motor 50 installed on the top of the movable plate 43 to drive the stirring rod 51 to rotate. The output shaft of the second motor 50 passes through the top of the movable plate 43 and is coaxially connected to the stirring rod 51. The bottom end of the stirring rod 51 passes through the top of the top cover 3 and extends into the inner tank 7. The outer wall of the stirring rod 51 is equipped with multiple stirring blades 52, which are used to disperse the activated carbon and evenly mix the liquid. The bottom end of the stirring rod 51 is rotatably connected to a conical bottom plate 6. The bottom of the decolorizing tank 1 is equipped with a discharge pipe 10 with a valve. The discharge pipe 10 first discharges the decolorized liquid and then discharges the used activated carbon. It is not necessary to disassemble the inner tank 7, which effectively improves the replacement efficiency of the activated carbon.

[0034] In this embodiment, an annular support plate 8 is provided on the inner wall of the decolorizing kettle body 1 near the top to fix the inner barrel 7 and prevent it from shaking. An annular hanging plate 71 is provided on the outer wall of the inner barrel 7 near the top. The bottom of the annular hanging plate 71 abuts against the top of the annular support plate 8 to stabilize the position of the inner barrel 7.

[0035] Specifically, the top of the annular support plate 8 is provided with multiple positioning holes 80, and the bottom of the annular hanging plate 71 is provided with multiple positioning posts 72 arranged in a circular array. The bottom ends of the multiple positioning posts 72 pass through the multiple positioning holes 80 respectively, thereby realizing the positioning and installation of the inner barrel 7.

[0036] Furthermore, a control valve is provided on the feed pipe 30, and a pipe cap 31 is fitted on the top of the feed pipe 30. After adding the solution and activated carbon, the pipe cap 31 is fitted on the top of the feed pipe 30 to prevent dust from entering the feed pipe 30.

[0037] Furthermore, a positioning vertical rod 44 is provided between the upper and lower sides of the inner wall of the U-shaped fixed plate 40, and the movable plate 43 is slidably connected to the outside of the positioning vertical rod 44 to limit the movement direction of the movable plate 43 and ensure its stability during lifting.

[0038] Furthermore, when the movable plate 43 rises to its highest point, the outer edge of the top of the conical base plate 6 fits into the bottom of the inner barrel 7, at which point the activated carbon is confined inside the inner barrel 7, ensuring the smooth progress of the decolorization process.

[0039] Furthermore, when the movable plate 43 descends to its lowest point, the outer edge of the top of the conical bottom plate 6 is 4-8 cm away from the bottom of the inner barrel 7. At this time, the activated carbon can fall smoothly from the inner barrel 7 down to the discharge pipe 10, achieving rapid discharge.

[0040] In this embodiment, the activated carbon rapid decolorization kettle is used by adding the liquid to be treated into the decolorization kettle body 1 through the feed pipe 30, and adding an appropriate amount of activated carbon through the feed pipe 30 as needed. Then, the control valve on the feed pipe 30 is closed, and the pipe cover 31 is placed on the top of the feed pipe 30 to prevent external dust from entering. The electric heater 2 is started to heat the liquid in the decolorization kettle body 1, and the external temperature controller is adjusted to heat the liquid to a suitable decolorization temperature, thereby providing a good environment for the adsorption reaction of activated carbon.

[0041] Start the stirring unit 5, and drive the stirring rod 51 to rotate through the second motor 50. The stirring blades 52 on the stirring rod 51 start to mix the liquid and activated carbon at high speed to ensure that the activated carbon is evenly dispersed in the liquid and fully adsorbs impurities and pigments.

[0042] After the stirring is completed and the predetermined stirring time is reached, the stirring component 5 and the electric heater 2 are turned off, allowing the liquid and activated carbon to complete the decolorization reaction. Then, the valve of the discharge pipe 10 is opened to first discharge the purified liquid after decolorization. Then, the lifting component 4 is started to move the movable plate 43 downward. The rotation of the screw 41 drives the conical bottom plate 6 to gradually descend and separate from the bottom of the inner barrel 7. At this time, the activated carbon falls from the bottom of the inner barrel 7 to the bottom of the decolorization kettle 1 and enters the discharge pipe 10 to discharge the used activated carbon. The entire discharge process is fast and efficient, without the need for manual cleaning or disassembly of the inner barrel 7, which greatly improves the decolorization effect and production efficiency.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
