Description

Technical Field

[0001] This invention relates to the field of activated coke particle cleaning technology, and particularly to an activated coke filter media separation and cleaning device. Background Technology

[0002] Granular activated carbon is a commonly used adsorption material in water treatment processes, such as in activated carbon adsorption tanks and activated carbon adsorption towers. After a certain period of use, granular activated carbon filter media will experience problems such as the pores on the activated carbon surface becoming clogged with suspended solids, and some material suffering frictional damage resulting in coke powder. Clogged pores lead to a decrease in adsorption capacity, while coke powder loses its adsorption capacity, and when it disturbs the water surface, it produces black water, significantly impacting the quality of the effluent. Therefore, activated carbon filter media must be cleaned or replaced periodically to remove suspended solids and coke powder from the activated carbon surface.

[0003] The current conventional practice is to use water backwashing combined with aeration for cleaning. Its advantages are simple structure and common application in traditional fixed-bed activated coke adsorption tanks. However, this cleaning method has low cleaning intensity and cannot effectively clean suspended solids and coke powder from the surface of activated coke in deep adsorption towers (adsorption layers exceeding 4 meters), easily leading to caking. Moreover, the cleaning water volume is large, generating a corresponding amount of wastewater. During backwashing, the equipment must be shut down for water treatment, reducing wastewater treatment efficiency. It also causes significant damage to the material, as activated coke filter media is not very strong to begin with, and air-water backwashing will greatly reduce its service life.

[0004] Currently, many engineering companies still use the principle of activated sand filters in the cleaning of activated adsorption towers. The contaminated filter media at the bottom of the filter is lifted by an air lift pump to a sand washer at the top of the filter. Turbulent flow separates the contaminants from the activated carbon, and the impurities are discharged through the cleaning water outlet. The clean activated carbon returns to the adsorption bed by gravity, thus achieving continuous filtration. Its advantages include continuous filtration without the need for backwashing, high efficiency, and no need for pretreatment of wastewater with high suspended solids (SS) content (influent SS can reach 150 mg / L). However, this cleaning method, with the cleaning unit located underwater, requires less adsorbent material to be loaded at the same adsorption height or volume, significantly reducing the thickness of the adsorption layer, lowering adsorption efficiency, and increasing civil engineering and equipment investment.

[0005] Therefore, the existing technology has problems and needs further improvement and development. Summary of the Invention

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to preferred embodiments. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0040] The accompanying drawings are schematic diagrams of embodiments of the present invention. It should be noted that these drawings are for illustrative purposes only and are not drawn to scale, and should not be construed as limiting the actual scope of protection of the present invention.

[0041] An activated carbon filter media cleaning device is provided for the mobile cleaning of activated carbon particles. The device includes a cleaning unit and a control unit connected to the cleaning unit, which controls the cleaning unit to perform mobile cleaning of the activated carbon particles.

[0042] The cleaning device includes a receiving system, a cleaning system 200, a drying system 300, and a separation system 400. The receiving system supports the cleaning system 200, the drying system 300, and the separation system 400, enabling their positional movement. The cleaning system 200 cleans the particulate activated coke to be cleaned, obtaining purified activated coke. The drying system 300 dries the purified activated coke, obtaining regenerated activated coke. The separation system 400 separates the particulate activated coke and powdered activated coke from the regenerated activated coke.

[0043] The control device includes a central control unit, a cleaning control unit, a drying control unit, a separation control unit, and an input unit. The input unit inputs a start command for the cleaning device to the control device. The central control unit sends corresponding control commands to the cleaning control unit, drying control unit, and separation control unit based on the start command. The cleaning control unit controls the cleaning system 200 of the cleaning device according to the corresponding control command to clean the granular activated carbon entering the cleaning device, obtaining purified activated carbon. The drying control unit controls the drying system 300 of the cleaning device according to the corresponding control command to dry the purified activated carbon, obtaining regenerated activated carbon. The separation control unit controls the separation system 400 of the cleaning device according to the corresponding control command to separate the regenerated activated carbon, separating activated carbon with a diameter smaller than a specified diameter from activated carbon with a diameter greater than or equal to a specified diameter, obtaining granular activated carbon and powdered activated carbon. Granular activated carbon refers to activated carbon with a diameter greater than or equal to the diameter of activated carbon particles used for water purification, i.e., activated carbon with a diameter greater than or equal to a specified diameter. The powdered activated carbon refers to activated carbon with a diameter smaller than that used in water purification, i.e., activated carbon with a diameter smaller than a specified diameter.

[0044] like Figure 1 As shown, the cleaning system 200, the drying system 300 and the separation system 400 are respectively arranged on the receiving system. Specifically, the drying system 300 is adjacent to the cleaning system 200, and the separation system 400 is adjacent to the drying system 300.

[0045] The receiving system includes a support mechanism and a traveling mechanism. The support mechanism includes a frame 101 and a support plate 102. The traveling mechanism includes traveling wheels 103. The frame supports the support plate 102, and the support plate 102 is fixed to the side of the frame 101 away from the ground. There are multiple traveling wheels 103, specifically any integer greater than or equal to three. The multiple traveling wheels 103 are evenly fixed to the side of the frame 101 closest to the ground.

[0046] The cleaning system 200, the drying system 300, and the separation system 400 are respectively fixed to the side of the support plate 102 away from the ground.

[0047] A feed inlet 104 is provided on the side of the supporting mechanism away from the traveling wheel 103, and the feed inlet 104 is located at the end of the cleaning system 200 away from the frame 101. The feed inlet 104 is connected to the cleaning inlet 201 at the center of the end of the cleaning system 200 away from the frame 101 through a first transmission channel 105. The first transmission channel 105 can be a semi-open structure or a closed structure, and no specific limitation is made here.

[0048] The cleaning system 200 is a vertically arranged cylindrical structure, including a primary cleaning mechanism, a secondary cleaning mechanism, and a cleaning discharge mechanism. The primary cleaning mechanism performs a first-level cleaning of the particulate activated carbon entering the cleaning system 200, specifically cleaning larger impurities on the surface of the particulate activated carbon, such as feathers and lint. The secondary cleaning mechanism performs a second-level cleaning of the particulate activated carbon after passing through the primary cleaning mechanism, specifically rinsing it to remove smaller substances such as organic matter and plasma adsorbed by the particulate activated carbon. The particulate activated carbon that has been cleaned by the primary and secondary cleaning mechanisms is purified activated carbon, and the cleaning discharge mechanism discharges the purified activated carbon (the cleaned particulate activated carbon) from the cleaning system 200.

[0049] The secondary cleaning mechanism is fitted around the outer ring of the primary cleaning mechanism, meaning the primary cleaning mechanism is located within the secondary cleaning mechanism. The horizontal position of the primary cleaning mechanism near the receiving system is lower than the horizontal position of the secondary cleaning mechanism near the receiving system; that is, the distance between the secondary cleaning mechanism and the supporting mechanism is less than the distance between the primary cleaning mechanism and the supporting mechanism. The cleaning discharge mechanism is fitted around the outer ring of the secondary cleaning mechanism, meaning the secondary cleaning mechanism is located within the cleaning discharge mechanism. The primary cleaning mechanism, the secondary cleaning mechanism, and the cleaning discharge mechanism are coaxially arranged. The end of the primary cleaning mechanism near the receiving system is connected to a first motor 216 via a rotating shaft 215. When the first motor 216 rotates, it drives the primary cleaning mechanism, the secondary cleaning mechanism, and the cleaning discharge mechanism to rotate simultaneously.

[0050] The primary cleaning mechanism includes a primary cleaning tank 211, an activated carbon adjusting plate 212, and a cleaning water tank 213. The primary cleaning tank 211 is cylindrical, and the cleaning water tank 213 is positioned on the outer ring of the end of the primary cleaning tank 211 closest to the receiving system; that is, the end of the primary cleaning tank 211 closest to the receiving system is placed inside the cleaning water tank 213. The end of the primary cleaning tank 211 closest to the receiving system and the end of the cleaning water tank 213 closest to the receiving system form a single integrated structure.

[0051] The sidewall of the primary cleaning tank 211 has a mesh structure. The mesh diameter of the portion of the primary cleaning tank 211 placed inside the cleaning water tank 213 is smaller than the diameter of the particulate activated carbon placed in the cleaning system. The mesh diameter of the portion of the primary cleaning tank 211 placed outside the cleaning water tank 213 is greater than or equal to the diameter of the particulate activated carbon.

[0052] The primary cleaning tank 211 has a rotating shaft 215 at one end near the cleaning water tank 213. The end of the rotating shaft 215 away from the primary cleaning tank 211 is connected to a first motor 216. The first motor 216 drives the primary cleaning tank 211 and the cleaning water tank 213 to rotate through the rotating shaft 215. The end of the cleaning water tank 213 away from the receiving system contacts the bottom 223 of the secondary tank, but is not fixed.

[0053] An adjusting mechanism is installed on the inner wall (bottom inner wall of the first-stage cleaning tank 211) near the end of the cleaning water tank 213. This adjusting mechanism is used to adjust the vertical position of the granular activated carbon in the first-stage cleaning tank 211. The adjusting mechanism includes an adjusting body 214 and an activated carbon adjusting plate 212. One end of the adjusting body 214 is fixed to the bottom inner wall of the first-stage cleaning tank 211, and the other end is fixedly connected to the activated carbon adjusting plate 212. The adjusting body 214 may consist of two telescopic rods arranged on the same straight line on the bottom surface of the first-stage cleaning tank 211, and positioned on either side of the center of the bottom surface of the first-stage cleaning tank 211. The activated carbon adjusting plate 212 is circular, and its center is parallel to the side wall of the first-stage cleaning tank 211 when connected to the center of the bottom surface of the first-stage cleaning tank 211. The difference between the diameter of the activated carbon adjusting plate 212 and the diameter of the bottom surface of the first-stage cleaning tank 211 is less than the diameter of the granular activated carbon placed in the cleaning system. A protective ring is provided along the edge of the activated carbon adjusting plate 212, that is, on the side surface opposite to the side wall of the primary cleaning tank 211. This protective ring is used to prevent broken activated carbon particles or impurities washed off from the cleaning process from entering the accommodating space between the activated carbon adjusting plate 212 and the bottom surface of the primary cleaning tank 211. The protective ring can be a rubber ring or other materials with good elasticity; no specific limitations are imposed here.

[0054] The first-stage cleaning tank 211 has wavy protrusions on the side wall of the part placed on the cleaning water tank 213 to increase the cleaning capacity of the first-stage cleaning mechanism.

[0055] The primary cleaning tank 211 is positioned on a portion of the side wall of the cleaning water tank 213 and equipped with a deep cleaning machine. This deep cleaning machine is used to clean and collect larger impurities from the surface of the particulate activated coke. Multiple deep cleaning machines can be installed, specifically any integer greater than or equal to one. Here, we take two deep cleaning machines as an example. The two deep cleaning machines are respectively installed on the side wall of the primary cleaning tank 211 with the same diameter, meaning they are symmetrical about the central axis of the primary cleaning tank 211.

[0056] The deep cleaning machine includes a cleaning brush 217 and a sewage discharge device. An impurity collection space 2173 is provided on the side wall of the primary cleaning tank 211. The cleaning brush 217 is located at the connection between the primary cleaning tank 211 and the impurity collection space 2173 and is used to clean the activated carbon particles to be cleaned in the primary cleaning tank 211. The sewage discharge device is located in the impurity collection space 2173 and is used to discharge the impurities collected in the impurity collection space 2173.

[0057] Specifically, such as Figure 5 As shown, impurity collection spaces 2173 are symmetrically arranged on the sidewalls of the primary cleaning tank 211 with the same diameter. These impurity collection spaces are preferably cylindrical. The cleaning brush 217 is cylindrical, with cleaning bristles evenly distributed on its outer sidewall. The cleaning brush 217 is fixed to the sidewall of the primary cleaning tank 211 by a rotating roller 2171, and is parallel to the sidewall of the primary cleaning tank 211. At this time, half of the cleaning brush 217 is placed inside the primary cleaning tank 211, and the other half is placed in the impurity collection space 2173. The rotating roller 2171 is parallel to the sidewall of the primary cleaning tank 211, and its two ends are respectively located on the primary cleaning tank 211 at both ends of the impurity collection space 2173. The rotating roller 2171 is parallel to the sidewall of the primary cleaning tank 211.

[0058] Scrapers 2172 are respectively installed at the junction of the impurity collection space 2173 and the interior of the primary cleaning tank 211. The scrapers 2172 are used to retain impurities from the cleaning particles of activated coke on the cleaning brush 217 in the impurity collection space 2173. The scrapers 2172 are parallel to the cleaning brush 217, and their length in the direction parallel to the cleaning brush 217 is equal to the length of the impurity collection space 2173. The scrapers 2172 are arc-shaped in the direction perpendicular to the cleaning brush 217, with their center located on the side of the impurity collection space 2173 away from the primary cleaning tank 211.

[0059] The difference between the width of the impurity collection space 2173 at the connection point with the primary cleaning tank 211 and the diameter of the cleaning brush 217 is greater than or equal to 0 and less than twice the chord length of the scraper.

[0060] The impurity collection space 2173 has a sewage outlet 2181 at the end away from the receiving system. The sewage outlet 2181 is connected to the end of the impurity collection space 2173 away from the receiving mechanism through a sewage channel 2184. The sewage outlet 2181 and the sewage channel 2184 are both on the same vertical line as the impurity collection space 2173, and their shapes and diameters are the same as those of the impurity collection space 2173.

[0061] The impurity collection space 2173 is located on the bottom part outside the primary cleaning tank 211, and the sewage discharge device is installed thereon. The sewage discharge device discharges the impurities in the impurity collection space 2173 through the sewage discharge channel 2184 to the sewage discharge outlet 2181.

[0062] A preferred embodiment of the sewage discharge device is described here: the sewage discharge device includes a sewage discharge push plate 2182 and a sewage discharge push rod 2183. One end of the sewage discharge push rod 2183 is fixed to the end of the impurity collection space 2173 away from the receiving system, and the other end is fixedly connected to the sewage discharge push plate 2182. The shape and size of the sewage discharge push plate 2182 are the same as those of the impurity collection space 2173 in the direction perpendicular to the cleaning brush 217.

[0063] The cleaning system 200 can also be fed with cleaning water from the primary cleaning mechanism through the feed inlet 104.

[0064] The portion of the discharge tank 231 opposite the secondary cleaning tank 221 is cylindrical. The discharge tank, positioned below the secondary cleaning tank 221 (near the receiving system end), forms a accommodating space composed of two spherical surfaces. The diameter of the outer spherical surface is equal to the diameter of the cylindrical portion of the discharge tank 231 furthest from the receiving system, and the diameter of the inner spherical surface is equal to the diameter of the secondary cleaning tank 221. The space between the outer and inner spherical surfaces communicates with the space at the end of the discharge tank 231 furthest from the receiving system, forming an accommodating space. The space between the outer and inner spherical surfaces has a horizontal cross-section, causing the discharge tank 231 to form two parts vertically. The upper vertical part and the lower vertical part are in diametrical contact but not connected. When the first motor 216 drives the cleaning system to rotate, the upper vertical part of the discharge tank 231 rotates, while the lower vertical part does not generate torque. The lower vertical part of the discharge tank 231 can be fixed to the support plate 102 by a support rod. The vertically upper portion of the discharge tank 231 is supported by a support rod fixed to the support plate 102. The support rod between the cleaning water tank and the support plate 102 can be located on both sides of the cleaning outlet 202, or the central axis of the support rod between the cleaning water tank and the support plate 102 can coincide with the central axis of the primary cleaning tank 211, and the cleaning outlet 202 can be located on one side of the support rod.

[0065] The secondary cleaning mechanism includes a secondary cleaning tank 221 and a water storage tank 224. The secondary cleaning tank 221 is fitted onto the portion of the primary cleaning tank 211 that is outside the primary cleaning water tank 213. The end of the secondary cleaning tank 221 closest to the primary cleaning water tank 213 forms the bottom surface of the secondary cleaning tank 221: the secondary tank bottom 223. The secondary tank bottom 223 has a mesh structure, and its mesh diameter is smaller than the diameter of the granular activated carbon. A water storage tank 224 is provided between the secondary cleaning tank 221 and the primary cleaning water tank 213. Water from the secondary cleaning tank 221 enters the water storage tank 224 through the mesh of the secondary tank bottom 223. A water storage outlet 225 is provided at the end of the water storage tank closest to the primary cleaning water tank 213. A water storage valve is provided on the water storage outlet 225, and the water storage valve is connected to the control device.

[0066] The bottom of the cleaning water tank 213 is provided with a drain outlet, and the drain outlet is equipped with a drain valve for draining the cleaning water in the cleaning water tank 213. When it is necessary to drain the cleaning water in the cleaning water tank 213, the cleaning control unit of the control device controls the first motor to stop rotating, and the administrator connects the drain outlet to the drain pipe and opens it, or the administrator enters a drain command for the cleaning water tank 213 to drain the cleaning water in the cleaning water tank 213.

[0067] The diameter difference between the secondary cleaning tank 221 and the primary cleaning tank 211 is greater than the diameter difference between the cleaning water tank 213 and the primary cleaning tank 211. The diameter of the water storage tank 224 is equal to the diameter of the secondary cleaning tank 221. A water storage outlet 225 is provided at one end of the water storage tank 224 near the cleaning water tank 213, and the water storage outlet 225 only needs to be located within the diameter range of the cleaning water tank 213. Multiple water storage outlets 225 can be provided to quickly discharge water from the water storage tank 224 into the cleaning water tank 213.

[0068] The sidewall of the secondary cleaning tank 221 includes a first tank body and a second tank body. The first tank body and the second tank body form a secondary cleaning tank sidewall with an adjustable mesh diameter. The adjustable diameter is smaller than or greater than or equal to the diameter of the particulate activated carbon. Specifically, the first tank body and the second tank body are in contact with each other. Both the first tank body and the second tank body have a mesh structure. The mesh diameter of the first tank body and the second tank body is larger than the diameter of the particulate activated carbon in the cleaning system, but less than twice the diameter of the particulate activated carbon in the cleaning system. The first tank body is positioned near the primary cleaning tank 211 and fixed to the secondary tank bottom 223. The second tank body is fitted onto the first tank body and placed on the secondary tank bottom 223. The second tank body can rotate on the secondary tank bottom 223 to adjust the relative position of the second tank body and the first tank body. The edge of each mesh on the first tank body corresponds to the edge of each mesh on the second tank body, that is, each mesh on the first tank body can coincide with the mesh on the second tank body. A first fixing post and a second fixing post are provided at the end of the first barrel body away from the bottom 223 of the secondary barrel, and a fixing bolt is provided at the end of the second barrel body away from the bottom 223 of the secondary barrel. When the fixing bolt is fixed to the first fixing post, the mesh on the first barrel body and the second barrel body overlaps, and the particulate activated carbon can enter the cleaning and discharge mechanism through the side wall of the secondary cleaning barrel 221. When the fixing bolt is fixed to the second fixing post, the mesh on the first barrel body and the second barrel body is misaligned, and the particulate activated carbon cannot enter the cleaning and discharge mechanism through the side wall of the secondary cleaning barrel 221.

[0069] A nozzle 222 is installed on the inner wall of the secondary cleaning tank 221 at the end away from the cleaning water tank 213. When the particulate activated carbon enters the secondary cleaning tank 221, the nozzle 222 is connected to a water source and performs secondary cleaning (rinsing) on ​​the particulate activated carbon that enters the secondary cleaning tank 221 to obtain purified activated carbon.

[0070] The number of nozzles 222 is any integer greater than or equal to 10, and the nozzles 222 are preferably high-pressure nozzles. After the secondary cleaning of the granular activated coke entering the secondary cleaning tank 221 is completed, the nozzles 222 are disconnected from the water source. The multiple nozzles 222 can be connected to a water distribution chamber, which is connected to a water source to ensure water supply connection for each nozzle 222.

[0071] The cleaning and discharge mechanism includes a discharge bucket 231 and a discharge channel 232. The discharge bucket 231 is fitted onto the secondary cleaning bucket 221, and the diameter of the discharge bucket 231 is larger than the diameter of the secondary cleaning bucket 221. The end of the discharge bucket 231 closest to the receiving system is the bottom of the discharge bucket 231, and the bottom of the discharge bucket 231 is fixedly connected to the bottom of the secondary bucket 223.

[0072] The bottom of the discharge tank 231 is provided with a purification outlet, which is connected to the cleaning outlet 202 located on the side of the cleaning system near the receiving system via the discharge channel 232. The purification outlet can be multiple outlets evenly distributed at the bottom of the discharge tank 231, or the bottom of the discharge tank 231 can be an open structure. The discharge channel 232, the side wall of the discharge tank 231, and the secondary cleaning tank 221 form a receiving space. When particulate activated carbon in the secondary cleaning tank 221 enters the discharge tank 231, the particulate activated carbon travels along the receiving space formed by the discharge channel 232, the side wall of the discharge tank 231, and the secondary cleaning tank 221 to the cleaning outlet 202.

[0073] The end of the secondary cleaning tank 221 and the discharge tank 231 furthest from the receiving system is preferably a closed structure or an openable structure.

[0074] A second transmission channel 106 is provided vertically below the cleaning outlet 202 (on the side closest to the receiving system). The end of the second transmission channel 106 away from the cleaning outlet 202 is connected to the drying inlet 301 of the drying system. The second transmission channel 106 conveys the purified activated carbon discharged from the cleaning outlet 202 to the drying system. The second transmission channel 106 may include three sidewalls in the direction connecting the cleaning outlet 202 and the drying inlet 301 of the drying system. In this case, the three sidewalls form a U-shaped groove with openings at both ends. The openings of the U-shaped groove are on the side away from the receiving system, and the openings at both ends are fixedly connected to the cleaning outlet 202 and the drying inlet 301 of the drying system, respectively. Alternatively, it may include four sidewalls, in which case the four sidewalls form a cuboid with openings at both ends, and the openings at both ends are fixedly connected to the cleaning outlet 202 and the drying inlet 301 of the drying system, respectively.

[0075] like Figure 6 As shown, the inner wall of the second transmission channel 106 near the receiving system is provided with a conveyor belt 1061. The starting end of the conveyor belt 1061 is located vertically below the cleaning outlet 202, and the ending end is located at the drying inlet 301 of the drying system 300 and extends into the drying system 300.

[0076] A protective plate 1062 is provided between the conveying start end of the conveyor belt 1061 and the cleaning outlet 202 in the transmission direction. One end of the protective plate 1062 is fixed to the side wall of the cleaning outlet 202 on the vertical side away from the conveyor belt 1061, and the other end is in contact with the conveyor belt 1061. It should be noted that the protective plate 1062 is positioned on the side of the conveyor belt 1061 away from the receiving system. The length of the protective plate 1062 in the transmission direction of the conveyor belt 1061 is greater than or equal to the distance between the side wall of the cleaning outlet 202 on the vertical side away from the conveyor belt 1061 and the side of the conveyor belt 1061 away from the receiving system.

[0077] The protective plate 1062 is preferably made of rubber. A support rod can be installed on the side of the protective plate 1062 closest to the receiving system to support the plate, thereby ensuring that the particulate activated coke discharged from the cleaning outlet 202 is placed on the conveyor belt 1061. A control plate 1063 is installed on the side wall of the cleaning outlet 202 closest to the drying system 300. The control plate 1063 controls the amount of particulate activated coke conveyed by the conveyor belt 1061. The distance between the end of the control plate 1063 furthest from the cleaning outlet 202 and the conveyor belt 1061 can be determined based on the amount of particulate activated coke conveyed. Specifically, the greater the amount of particulate activated coke conveyed, the greater the distance between the end of the control plate 1063 furthest from the cleaning outlet 202 and the conveyor belt 1061. The control plate 1063 divides the space of the second transmission channel 106 furthest from the receiving system in the transmission direction.

[0078] The drying system 300 includes a grid drying mechanism, which comprises a drying chamber 303, a grid body 304, a drying conveyor belt 305, and a drying device. The drying chamber 303 forms a drying accommodating space, and the grid body 304 divides the drying chamber 303 into multiple interconnected grid spaces to ensure the drying time of the purified activated coke. The drying conveyor belt 305 transports the purified activated coke from the drying inlet 301 to the drying outlet 302, and the drying device dries the particulate activated coke during the transport process.

[0079] like Figure 7As shown, the drying inlet 301 is located at one end of the drying chamber 303 near the cleaning system 200, specifically on the side wall or the top wall (the side of the drying chamber away from the receiving system). The drying conveyor belt 305 includes multiple first drying conveyor belts and multiple second drying conveyor belts, which are arranged alternately in sequence. Each first drying conveyor belt is parallel to each other, and each second drying conveyor belt is parallel to each other, while the first and second drying conveyor belts are perpendicular to each other.

[0080] The grid body 304 comprises multiple grid spaces, dividing the drying chamber into multiple grid spaces from near to far from the cleaning system, with each grid space interconnected. The first drying conveyor belt is disposed in each grid space, and the second drying conveyor belt is disposed at the space connecting every two adjacent grid spaces. The drying conveyor belts 305 decrease in vertical position from near to far from the cleaning system 200, and the central axis of the starting end of the vertically lower drying conveyor belt 305 is vertically below the ending end of the upper drying conveyor belt 305. It should be noted that every two adjacent drying conveyor belts 305 must ensure that the activated carbon particles are sequentially conveyed to the lower drying conveyor belt 305. Protective edges may also be provided on both sides of the drying conveyor belt 305, with the distance between the protective edges and the drying conveyor belt 305 being less than the diameter of the activated carbon particles. The highest point of the protective edges is lower than the lowest point of the drying device.

[0081] A grid body 304 is respectively provided between the two adjacent first drying conveyor belts. The width of the grid body 304 is smaller than the width of the drying chamber 303. The grid body 304 is parallel to both ends of the first drying conveyor belt, with one end fixed to the side wall of the drying chamber 303 and the other end connected to / adjacent to the protective edge of the second drying conveyor belt.

[0082] The drying device is installed inside the grid body 304. The grid body 304 has a drying port on its side facing the first drying conveyor belt. The surface of the drying port may be provided with a protective net. The drying device dries the granular activated coke through the drying port. The drying device may also be installed inside the drying chamber 303, and the protective net may also be provided on the inner wall surface of the chamber where the drying device is installed.

[0083] The drying chamber 303 is located at the end furthest from the cleaning system and at the side closest to the receiving system, where the drying outlet 302 is located. The drying outlet 302 discharges the particulate activated coke from the first drying conveyor belt furthest from the cleaning system 200 into the drying system 300, thus obtaining regenerated activated coke.

[0084] The separation system 400 is located on the side of the drying chamber 303 near the receiving system, and the drying outlet 302 is connected to the separation inlet 401 of the separation system 400. The separation system 400 includes a first separation tank 404, a second separation tank 405, and a second motor 406. The first separation tank 404 separates the powdered activated carbon from the regenerated activated carbon, placing the granular activated carbon in the first separation tank 404, and exporting the regenerated granular activated carbon through the regenerated activated carbon outlet 402, facilitating the recycling of the regenerated granular activated carbon. The second separation tank 405 collects the separated powdered activated carbon and exports it through the powdered activated carbon outlet 403, facilitating the recycling of the powdered activated carbon after remodeling. Granular activated carbon refers to regenerated activated carbon with a diameter conforming to the standard activated carbon standard, while powdered activated carbon refers to regenerated activated carbon with a diameter smaller than the standard activated carbon standard.

[0085] The separation system is provided with a support rod at one end near the receiving system. There are at least two support rods. One end of the support rod is fixed to the support plate 102, and the other end is provided with a protective pad and is adjacent to the separation system to ensure the stability of the separation system when it rotates.

[0086] like Figure 4 As shown, the second separating barrel 405 is fitted onto the first separating barrel 404, and the side walls of the first separating barrel 404 and the second separating barrel 405 form a ring. The ends of the side walls of the first separating barrel 404 and the second separating barrel 405 furthest from the receiving system are fixedly connected by an annular plate, making the first separating barrel 404 and the second separating barrel 405 a single unit. The separation inlet 401 is located at the center of the first separating barrel 404, opposite the receiving system.

[0087] The first separating tank 404 has a connecting shaft at its center near the receiving system. This connecting shaft is connected to the second motor 406, which drives the separating system 400 to rotate via the connecting shaft. The second motor 406 is connected to the control device, which controls the speed and direction of the second motor 406. A fixed shaft is fixed to the end of the second motor 406 furthest from the first / second separating tank. The central axis of the fixed shaft coincides with the central axis of the separating system. The end of the fixed shaft furthest from the second motor 406 is fixed to the support plate 102. When the fixed shaft passes through the separating system, it contacts but does not connect to other structures. Gaskets can be placed between the fixed shaft and other structures to ensure the rotation of the separating system 400 and prevent leakage of activated carbon from the separating system.

[0088] The sidewall of the first separation tank 404 has a mesh structure with a mesh diameter smaller than that of the granular activated coke. When the second motor 406 drives the separation system 400 to rotate, the regenerated activated coke with a diameter smaller than that of the standard granular activated coke enters the second separation tank 405.

[0089] The first separation tank 404 has a regenerated activated coke outlet 402 near the receiving system. The regenerated activated coke outlet 402 is equipped with a regenerated activated coke valve. When the regenerated activated coke valve is opened, the particulate activated coke in the first separation tank 404 is discharged. Preferably, there are two regenerated activated coke outlets 402, each located on an extension line of the same diameter of the fixed shaft, ensuring the stability of the separation system when the regenerated activated coke outlets 402 are connected to the first separation tank 404.

[0090] The first separation tank 404 has multiple separation outlets at the end away from the separation inlet 401. Each separation outlet is equipped with a separation door. A connecting channel is provided between the separation outlet and the regenerated activated carbon outlet 402. The end of the connecting channel near the regenerated activated carbon outlet 402 converges with the regenerated activated carbon outlet 402.

[0091] The first separating tank 404 and the second separating tank 405 are connected to each other at their ends near the receiving system and are funnel-shaped. The portion of the funnel-shaped funnel 405 located away from the separating inlet 401 on both sides of the fixed shaft is connected to the powder activated coke outlets 403 on both sides of the fixed shaft. Regenerated activated coke particles with a diameter smaller than that of standard particle activated coke enter the second separating tank 405 and are discharged from the separation system through the powder activated coke outlets 403. Preferably, there are two powder activated coke outlets 403, and their connecting line coincides with the diameter of the fixed shaft, thereby ensuring the stability of the separation system during rotation.

[0092] The second separating bucket 405, near the receiving system, consists of two spherical surfaces. The diameter of the outer spherical surface is equal to the diameter of the column at the end of the second separating bucket 405 furthest from the receiving system, and the diameter of the inner spherical surface is equal to the diameter of the first separating bucket 404. The space between the outer and inner spherical surfaces communicates with the space at the end of the second separating bucket 405 furthest from the receiving system, forming an accommodating space. The space between the outer and inner spherical surfaces has a horizontal cut-off surface, causing the second separating bucket 405 to form two parts vertically. The upper vertical part and the lower vertical part are in diametrical contact but not connected. When the second motor drives the first separating bucket 404 to rotate, the upper vertical part of the second separating bucket 405 rotates, while the lower vertical part does not generate torque. The lower vertical part of the second separating bucket 405 can be fixed to the support plate 102 by a support rod between the second motor 406 and the support plate 102. The upper vertical parts of the first separating bucket 404 and the second separating bucket 405 are supported by the support rod fixed to the support plate 102.

[0093] The control device can be fixed to the side of the support mechanism; its position is not restricted here.

[0094] During activated coke cleaning, the cleaning device is pushed to the target position via wheels 103. The inlet 104 of the cleaning device is connected to the outlet of the activated coke particles to be cleaned, which can be via a conduit or other means; no specific limitation is made here. The activated coke particles to be cleaned enter the primary cleaning tank 211 through the inlet 104. Before the activated coke particles enter the primary cleaning tank 211, primary cleaning water can be added through the inlet 104, or the central control unit of the device can send a water discharge command to the cleaning control unit via the water storage outlet 225. The water storage valve of the cleaning control unit opens, allowing the stored water after rinsing in the water storage tank 224 to be simultaneously discharged into the cleaning water tank 213. Water enters the primary cleaning tank 211 through the mesh on the side wall, ensuring full contact with the activated coke particles to be cleaned.

[0095] After the activated coke particles to be cleaned are fed in, the central control unit sends a cleaning command to the cleaning control unit. The cleaning control unit controls the first motor 216 to rotate in cleaning mode. Under the rotation of the primary cleaning tank 211, the primary cleaning water and the activated coke particles to be cleaned rotate synchronously. The cleaning brush 217 rotates in the same direction under the rotation of the primary cleaning water and cleans the activated coke particles to be cleaned. At this time, larger impurities on the surface of the activated coke particles to be cleaned are cleaned by the cleaning brush 217 and adhere to the surface of the cleaning brush 217. When the cleaning brush 217 with impurities enters the impurity collection space 2173, it continues to rotate under the rotation of the water flow. When the cleaning brush 217 with impurities rotates to the junction of the impurity collection space 2173 and the space inside the primary cleaning tank 211, the scraper 2172 scrapes the cleaning brush 217, causing the impurities on the cleaning brush 217 to fall into the impurity collection space 2173.

[0096] The first motor 216 can rotate alternately in cleaning mode, rotating 3 revolutions clockwise and 3 revolutions counterclockwise, with a rotation speed of 30 r / min.

[0097] The central processing unit may be configured with a time limit for cleaning the impurity collection space 2173. When the cleaning time of the primary cleaning tank 211 equals the time limit, the central processing unit sends an impurity removal command to the cleaning control unit. At this time, the discharge push rod 2183 extends, moving the discharge push plate 2182 along the discharge channel 2184 away from the receiving system, thus discharging the impurities from the impurity collection space 2173. When the central processing unit sends an impurity removal command to the cleaning control unit, the display unit of the control device displays the impurity removal command issued by the central processing unit, prompting the administrator to clean the impurities in a timely manner; the cleaning control unit suspends the cleaning operation of the primary cleaning tank 211. After the sewage pusher plate 2182 pushes the impurities out of the sewage channel 2184 for a first time threshold, the sewage push rod 2183 retracts, causing the sewage pusher plate 2182 to move along the sewage channel 2184 toward the receiving system. When the length of the sewage push rod 2183 is at its shortest length, the sewage pusher plate 2182 is placed at one end of the impurity collection space 2173 near the receiving system, that is, the sewage pusher plate 2182 is reset.

[0098] After the sewage discharge push plate 2182 is reset, the cleaning control unit continues to start the cleaning operation of the primary cleaning tank 211.

[0099] When the cleaning operation of the primary cleaning tank 211 reaches the second time threshold, the cleaning control unit controls the adjusting body 214 to push the activated carbon adjusting plate 212 towards the secondary cleaning tank. When the adjusting body 214 is at its maximum length, the activated carbon adjusting plate 212 and the bottom surface of the secondary cleaning tank 221 near the receiving system are on the same plane. At the same time, the display unit displays that the primary cleaning is complete, reminding the administrator to check whether the mesh on the first tank and the second tank is misaligned. If the mesh on the first tank and the second tank overlaps, the administrator fixes the fixing bolt to the second fixing post.

[0100] When the length of the adjusting body 214 is at its maximum, the cleaning control unit controls the first motor 216 to rotate in a drum-changing mode. When the duration of the first motor 216 rotating in the drum-changing mode reaches a third time threshold, the first motor 216 ends the drum-changing mode, and the particulate activated coke that has undergone primary cleaning in the primary cleaning drum 211 enters the secondary cleaning drum 221. The rotation mode of the first motor 216 in the drum-changing mode can be clockwise or counterclockwise, and the rotation speed is 120 r / min.

[0101] When the first motor 216 rotates in the bucket-changing mode for a period of time reaching the third time threshold, the display module of the control device displays a water inlet prompt. The administrator connects the water distribution tank to the water source, and the nozzle 222 performs secondary cleaning (high-pressure rinsing) on ​​the granular activated carbon in the secondary cleaning tank 221. When the water inlet prompt display time reaches the fourth time threshold, the cleaning control unit controls the first motor 216 to rotate in the secondary cleaning mode. When the first motor 216 rotates in the secondary cleaning mode for a period of time reaching the fifth time threshold, the first motor 216 ends the secondary cleaning mode, the display module of the control device displays a water outage prompt, and the administrator disconnects the water distribution tank from the water source. When the water distribution tank is connected to the water source, the water sprayed by the nozzle 222 impacts the granular activated carbon in the secondary cleaning tank 221 and enters the water storage tank 224. When the primary cleaning tank 211 needs to be filled with cleaning water, the administrator can input a command to open the water storage valve through the input unit of the control device. The water in the water storage tank 224 enters the cleaning water tank 213. The water enters the primary cleaning tank 211 through the mesh on the side wall of the primary cleaning tank 211 and comes into full contact with the activated coke particles to be cleaned.

[0102] The first motor 216 can rotate alternately in the secondary cleaning mode, rotating half a turn clockwise and half a turn counterclockwise, with a rotation speed of 30 r / min.

[0103] When the control device's display module shows a water outage warning indicating that the sixth time threshold has been reached, the control device's display module will show that the second-level cleaning is complete, reminding the administrator to adjust the mesh alignment of the first and second tanks: the administrator will then fix the fixing bolts to the first fixing post.

[0104] When the display module indicates that the secondary cleaning has been completed and the seventh time threshold has been reached, the cleaning control unit controls the first motor 216 to rotate in discharge mode. The particulate activated coke that has undergone secondary cleaning in the secondary cleaning tank 221 enters the discharge tank 231 and is discharged from the cleaning system 200 through the cleaning outlet 202. The first motor 216 can rotate clockwise or counterclockwise in discharge mode, with a rotation speed of 120 r / min.

[0105] When the first motor 216 rotates in discharge mode for a duration that reaches the eighth time threshold, the first motor 216 ends the discharge mode, and the particulate activated coke that has undergone secondary cleaning in the secondary cleaning tank 221 enters the discharge tank 231.

[0106] When the first motor 216 is in discharge mode or when the first motor 216 ends discharge mode, the central processing unit sends a drying command to the drying control unit. The drying control unit then starts the conveyor belt 1061 of the second transmission channel 106, the drying conveyor belt 305 in the drying system 300, and the drying device.

[0107] At this time, the conveyor belt 1061 quantitatively conveys the purified activated carbon from the cleaning outlet 202 to the drying inlet 301, and the purified activated carbon is evenly conveyed onto the drying conveyor belt 305. Under the conveying of the drying conveyor belt 305, the purified activated carbon sequentially passes through each grid space, and the drying device within the grid body 304 or the drying chamber 303 performs a drying operation on the passing purified activated carbon. Multiple grid spaces ensure the drying time of the purified activated carbon, thereby ensuring the dryness of the regenerated activated carbon obtained by the drying system 300. When the purified activated carbon has passed through all the grid spaces and is conveyed to the drying outlet 302, the purified activated carbon completes the drying operation, resulting in regenerated activated carbon. The regenerated activated carbon is conveyed to the drying outlet 302 by the conveyor belt 305 at its lowest position. After being delivered to the drying outlet 302, the regenerated activated carbon enters the first separation tank 404 through the separation inlet 401 of the separation system 400.

[0108] When the drying system 300 completes the drying operation of the purified activated coke, that is, when the drying control unit starts the conveyor belt 1061 of the second transmission channel 106, the drying conveyor belt 305 in the drying system 300 and the drying device for a period of time that reaches the ninth time threshold, the drying control unit shuts down the conveyor belt 1061 of the second transmission channel 106, the drying conveyor belt 305 in the drying system 300 and the drying device.

[0109] When the drying control unit shuts down the conveyor belt 1061 of the second transmission channel 106, the drying conveyor belt 305 in the drying system 300, and the drying device, the central processing unit sends a separation command to the separation control unit.

[0110] The separation control unit controls the rotation of the second motor 406. The rotation speed and direction of the second motor 406 can be clockwise or counterclockwise, with a rotation speed of 120 r / min. At this time, the powdered activated coke in the regenerated activated coke in the first separation tank 404 enters the second separation tank 405 through the mesh sidewall of the first separation tank 404 under centrifugal action.

[0111] When the second motor 406 rotates for a period of time reaching the tenth time threshold, the separation control unit controls the second motor 406 to stop rotating and opens the regenerated activated coke valve at the regenerated activated coke outlet 402 and the powdered activated coke valve at the powdered activated coke outlet 403, allowing the powdered activated coke to be discharged from the separation system. Simultaneously, the administrator opens the separation door at the separation outlet. At this time, the granular activated coke in the first separation tank 404 enters the regenerated activated coke outlet 402 and is discharged from the separation system along the regenerated activated coke outlet 402.

[0112] The separation system can separate the regenerated activated coke in portions to ensure the separation effect. At this time, a storage chamber is set between the drying outlet 302 and the separation inlet 401. The separation inlet 401 is equipped with a separation valve, which is connected to the control device.

[0113] It should be noted that the connection between the first transmission channel 105 and the cleaning inlet 201 is in contact but not fixed, meaning that the rotation of the cleaning system will not generate torque on the first transmission channel 105. Similarly, the connection channel between the separation inlet 401 and the drying outlet 302, at the end connected to the separation inlet 401, is in contact but not fixed, meaning that the rotation of the separation system will not generate torque on the drying system.

[0114] In an activated carbon filter media cleaning device, the first time threshold, the second time threshold, the third time threshold, the fourth time threshold, the fifth time threshold, the seventh time threshold, the eighth time threshold, the ninth time threshold, and the tenth time threshold are preset values, and the administrator can adjust their specific values ​​according to the quantity of granular activated carbon.

[0115] An activated carbon filter media cleaning device is a mobile activated carbon cleaning device. It features a spatially separated adsorption and cleaning process, employing a two-stage cleaning method to separately clean suspended solids on the surface of the granular activated carbon and smaller substances such as organic matter and plasma adsorbed by the granular activated carbon, ensuring effective cleaning. The cleaned activated carbon can be dried and separated, allowing for direct recycling of the granular activated carbon and reshaping of the powdered activated carbon. The device also maintains the diameter of the activated carbon in the granular activated carbon, preventing caking during use and improving the water purification efficiency of the activated carbon particles. Furthermore, it fully utilizes the space of the adsorption tower, maximizing the effective adsorption layer within the same tower structure, reducing the number of adsorption towers and lowering investment costs.

[0116] The above description illustrates preferred embodiments of the present invention and helps those skilled in the art to more fully understand the technical solution of the present invention. However, these embodiments are merely illustrative and should not be construed as limiting the specific implementation of the present invention to these embodiments. For those skilled in the art, several simple deductions and modifications can be made without departing from the inventive concept, and all such modifications should be considered within the protection scope of the present invention.
