[0032] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the utility model, rather than to limit the utility model. For those skilled in the art, the utility model can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the utility model by showing examples of the utility model.

[0033] like Figures 2 to 4As shown, the utility model provides an activated carbon separation device, which includes a filter tank 1, a filter mechanism 2, a liquid outlet pipeline 3 and a first cleaning pipeline 4. The filter tank 1 has a receiving chamber 11 inside, and an input pipe 12 communicating with the receiving chamber 11 is provided at the top of the filter tank 1, and the input pipe 12 is used to communicate with the solution providing device 8, and an output pipe 13 is provided at the side of the filter tank 1, and a first stop valve 14 is installed on the output pipe 13, and a discharge pipe 15 communicating with the receiving chamber 11 is provided at the bottom of the filter tank 1, and a second stop valve 16 is installed on the discharge pipe 15. The filter mechanism 2 is located in the receiving chamber 11 and is arranged in a cylindrical shape, and the top and bottom of the filter mechanism 2 are respectively sealed and connected with the filter tank 1, and a cylindrical channel 21 is provided between the filter mechanism 2 and the filter tank 1, and the cylindrical channel 21 is connected with the output pipe 13. The liquid outlet pipeline 3 is connected with the outlet end of the output pipe 13, and a third stop valve 31 is provided on the liquid outlet pipeline 3, and the liquid outlet pipeline 3 is used to communicate with the solution providing device 8. The first cleaning pipeline 4 is communicated with the outlet end of the output pipe 13 . A fourth stop valve 41 is provided on the first cleaning pipeline 4 . The first cleaning pipeline 4 is used to communicate with the pure water providing device 57 .

[0034] Specifically, the first stop valve 14 and the third stop valve 31 are opened, and then the solution providing device 8 delivers the solution to the accommodating chamber 11 of the filter tank 1 through the input pipe 12, and the solution flows to the cylindrical channel 21 through the filter mechanism 2, and the filter mechanism 2 can filter the solution, so that the activated carbon in the solution gradually adheres to the inner side of the filter mechanism 2 and forms an activated carbon layer. The solution filtered by the filter mechanism 2 will enter the cylindrical channel 21, and then the solution returns to the solution providing device 8 through the output pipe 13 and the liquid outlet pipeline 3. By circulating the solution between the solution providing device 8 and the filter tank 1, the solution is fully filtered, and the activated carbon in the solution is separated from the solution and adheres to the inner side of the filter mechanism 2. Then the third stop valve 31 is closed, the first stop valve 14 and the fourth stop valve 41 are opened, and the pure water supply device 57 delivers pure water with a preset pressure to the accommodating chamber 11 of the filter tank 1 through the first cleaning pipeline 4, and the pure water enters the cylindrical channel 21 through the first cleaning pipeline 4 and the output pipe 13, and the pure water flows to the accommodating chamber 11. At this time, the pure water will exert pressure on the activated carbon layer on the filter mechanism 2, so that the activated carbon layer on the filter mechanism 2 is broken and falls off from the filter mechanism 2; and in the process of the pure water flowing from the cylindrical channel 21 to the accommodating chamber 11 of the filter tank 1, the pure water can also flush the activated carbon remaining on the filter mechanism 2, so that the activated carbon is completely separated from the filter mechanism 2. After the pure water flushing is completed, the first stop valve 14 and the fourth stop valve 41 are closed, and the second stop valve 16 is opened, so that the pure water mixed with the activated carbon is discharged from the discharge pipe 15. The discharge pipe 15 can be connected to the activated carbon collection device so that the separated activated carbon can be recovered. Therefore, the activated carbon separation device of the utility model realizes the separation and recovery of activated carbon through the cooperation between the filtering mechanism 2, the liquid outlet pipeline 3 and the first cleaning pipeline 4. There is no need for on-site workers to recover the activated carbon by cleaning and manual flushing, which can greatly reduce the labor intensity of on-site workers and improve production efficiency.

[0035] In some embodiments, the cylindrical channel 21 can be a cylindrical channel or a conical channel, etc., as long as it can be distributed around the accommodating cavity 11, and the present invention does not impose any limitation.

[0036] like Figures 2 to 3 As shown, in some embodiments of the present invention, there are multiple output pipes 13 , and the multiple output pipes 13 are arranged at intervals in the axial direction of the filter mechanism 2 .

[0037] Specifically, providing a plurality of output pipes 13 can speed up the filtering speed of the solution, and the solution can be fully filtered at different heights.

[0038] like Figures 2 to 4As shown, in some embodiments of the present invention, the filter mechanism 2 includes a cylindrical filter screen 22, the top and the bottom of the filter screen 22 are respectively sealed and connected to the filter tank 1, and a cylindrical channel 21 is provided between the filter screen 22 and the filter tank 1. The filter screen 22 includes a plurality of filter layers sequentially attached along its radial direction. And along the radial outward direction of the filter screen 22, the apertures of the filter holes of the plurality of filter layers are sequentially reduced.

[0039] Specifically, the distribution density of the filter holes of the filter screen 22 is large and the filtering efficiency is high. Moreover, the structure of the filter screen 22 is relatively thin and light, which is convenient for positioning, installation and disassembly. In addition, the filter screen 22 includes a plurality of filter layers that are sequentially attached along its radial direction, and the aperture of the filter holes of each filter layer is different. The closer to the tank wall of the filter tank 1, the smaller the aperture of the filter hole of the filter layer; the closer to the axis of the filter screen 22, the larger the aperture of the filter hole of the filter layer. Therefore, when filtering the solution, the solution will first be filtered by the filter hole with a relatively large aperture, and then filtered by the filter hole with a relatively small aperture, which can improve the filtering efficiency on the one hand and prevent the filter screen 22 from being blocked by activated carbon on the other hand. Of course, those skilled in the art can set the aperture of the filter screen 22 as needed, and the utility model does not limit it. Preferably, the filter screen 22 is made of stainless steel. Preferably, the aperture range of the filter hole of the filter screen 22 is 30 microns to 60 microns.

[0040] In some embodiments, the filter screen 22 and the filter tank 1 may be sealed and connected by welding or bolting, and the present invention does not impose any limitation thereto.

[0041] Of course, the filter mechanism 2 may also be any other structural form that can achieve the above technical effects, and the present utility model does not impose any limitation thereto.

[0042] like Figures 2 to 3 As shown, in some embodiments of the present invention, the filter screen 22 includes a cylindrical filter screen upper portion 23 and a conical filter screen lower portion 24, the top of the filter screen upper portion 23 is sealed connected to the filter tank 1, the bottom of the filter screen upper portion 23 is sealed connected to the top of the filter screen lower portion 24, and the bottom of the filter screen lower portion 24 is sealed connected to the filter tank 1.

[0043] Specifically, the filter tank 1 includes an upper tank body and a lower tank body that are sealed and connected to each other. The upper tank body includes a top plate and a cylindrical upper tank wall, and the top plate is sealed and connected to the top of the upper tank wall. The lower tank body includes a conical lower tank wall and a bottom plate, the top of the lower tank wall is sealed and connected to the bottom of the upper tank wall, and the axis of the lower tank wall coincides with the axis of the upper tank wall, and the bottom plate is sealed and connected to the bottom of the lower tank wall. The inner diameter of the lower tank wall gradually increases from bottom to top, and the maximum inner diameter of the lower tank wall is equal to the inner diameter of the upper tank wall. The filter screen 22 includes a cylindrical filter screen upper part 23 and a conical filter screen lower part 24, the filter screen upper part 23 can be installed in the upper tank body, the filter screen lower part 24 can be installed in the lower tank body, and the spacing between the filter screen upper part 23 and the upper tank wall is equal to the spacing between the filter screen lower part 24 and the lower tank wall. Therefore, the filter screen 22 can be adapted to the specific shape of the filter tank 1, and the cylindrical channel 21 can have a substantially uniform width. In addition, the top output pipe 13 is horizontally opposite to the filter screen upper part 23, and the other output pipes 13 below can be horizontally opposite to the filter screen lower part 24 at different heights.

[0044] In some embodiments, the top and bottom of the filter upper part 23 are respectively sealed and connected to the filter tank 1, the top and bottom of the filter lower part 24 are respectively sealed and connected to the filter tank 1, a cylindrical first channel is formed between the filter upper part 23 and the filter tank 1, and a conical second channel is formed between the filter lower part 24 and the filter tank 1. The topmost output pipe 13 is connected to the first channel, and the other output pipes 13 below are connected to the second channel.

[0045] like Figure 2 As shown, in some embodiments of the utility model, the activated carbon separation device also includes a first liquid inlet pipeline 5 and a first liquid inlet branch 51. The first liquid inlet branch 51 is connected to the inlet end of the input pipe 12 through the first liquid inlet pipeline 5. The first liquid inlet branch 51 is provided with a fifth stop valve 52. The first liquid inlet branch 51 can be connected to the solution providing device 8, and the input pipe 12 is provided with a fourteenth stop valve 19.

[0046] Specifically, the fifth stop valve 52, the fourteenth stop valve 19, the first stop valve 14 and the third stop valve 31 are opened, and the solution providing device 8 can sequentially input liquid into the filter tank 1 through the first liquid inlet branch 51, the first liquid inlet pipeline 5 and the input pipe 12. The liquid enters the cylindrical channel 21 after being filtered by the filter screen 22, and then flows outward along the output pipe 13 and the liquid outlet pipeline 3 and returns to the solution providing device 8. After the liquid is filtered by the filter screen 22, the activated carbon will adhere to the inner side of the filter screen 22 and gradually form a dense activated carbon layer.

[0047] like Figure 2As shown, in some embodiments of the utility model, the activated carbon separation device further includes a second liquid inlet branch 53 and a second liquid inlet pipeline 55. The second liquid inlet branch 53 is connected to the inlet end of the input pipe 12 through the first liquid inlet pipeline 5, and the second liquid inlet branch 53 is provided with a sixth stop valve 54. The second liquid inlet branch 53 is used to communicate with the pure water supply device 57. The inlet end of the second liquid inlet pipeline 55 is connected to the outlet end of the first liquid inlet pipeline 5, and the outlet end of the second liquid inlet pipe is connected to the inlet end of the first cleaning pipeline 4, and the second liquid inlet pipeline 55 is provided with a seventh stop valve 56.

[0048] Specifically, the sixth stop valve 54, the seventh stop valve 56, the fourth stop valve 41 and the first stop valve 14 are opened, and the fourteenth stop valve 19, the third stop valve 31 and the second stop valve 16 are closed. The pure water supply device 57 can sequentially input pure water with a certain pressure to the output pipe 13 through the second liquid inlet branch 53, the first liquid inlet pipeline 5, the second liquid inlet pipeline 55 and the first cleaning pipeline 4. The pure water enters the cylindrical channel 21 through the output pipe 13, and the pure water will exert pressure on the activated carbon layer on the filter mesh 22, so that the activated carbon layer on the filter mesh 22 is broken and falls off from the filter mesh 22; in the process of pure water flowing from the cylindrical channel 21 to the accommodating chamber 11 of the filter tank 1, the pure water can also flush the activated carbon remaining on the filter mesh 22, so that all the activated carbon is separated from the filter mesh 22. After the pure water is applied, the second stop valve 16 is opened, and the pure water mixed with the activated carbon is discharged from the discharge pipe 15. The discharge pipe 15 can be connected to the activated carbon collection device to recover the separated activated carbon. Of course, the pure water supply device 57 can be a common device in the art, and the structure and principle of the utility model will not be described in detail.

[0049] like Figure 2 As shown, in some embodiments of the utility model, the side of the filter tank 1 is also provided with a plurality of backflush pipes 17, the plurality of backflush pipes 17 are arranged at intervals along the axial direction of the filter screen 22, the backflush pipes 17 are connected to the cylindrical channel 21, and an eighth stop valve 18 is provided on the backflush pipe 17. The activated carbon separation device also includes a first gas pipeline 6 and a second gas pipeline 62, the first gas pipeline 6 is connected to the inlet end of the backflush pipe 17, and a ninth stop valve 61 is provided on the first gas pipeline 6. The second gas pipeline 62 is connected to the outlet end of the output pipe 13, and a tenth stop valve 63 is provided on the second gas pipeline 642, and the first gas pipeline 6 and the second gas pipeline 62 can be connected to the sterile air providing device 66.

[0050] Specifically, in the process of the pure water providing device 57 inputting pure water into the filter tank 1, the eighth stop valve 18 and the ninth stop valve 61 are opened, and the sterile air providing device 66 delivers air to the backblowing pipe 17 through the first air supply pipeline 6. The air enters the cylindrical channel 21 through the backblowing pipe 17 and forms bubbles in the pure water. The bubbles will impact the activated carbon layer on the filter mesh 22, and the bubbles will also disturb the pure water, thereby improving the cleaning effect of the pure water, thereby making all the activated carbon separate from the filter mesh 22, and making the filter mesh 22 cleaner.

[0051] In addition, air can also be filled into the filter tank 1 after a sufficient amount of pure water is contained. When a sufficient amount of pure water is contained in the filter tank 1, the eighth stop valve 18 and the ninth stop valve 61 are opened, and the sterile air providing device 66 delivers air to the backflush pipe 17 through the first air supply pipeline 6, and the air enters the cylindrical channel 21 through the backflush pipe 17 and forms bubbles in the blown water; at the same time, the tenth stop valve 63 and the first stop valve 14 are opened, and the third stop valve 31 is closed, and the sterile air providing device 66 delivers air to the output pipe 13 through the second air supply pipeline 62, and the air enters the cylindrical channel 21 through the output pipe 13 and forms bubbles in the pure water.

[0052] In some embodiments, a vent pipe is also installed on the top of the filter tank 1, and the vent pipe is connected to the accommodating chamber 11 to make the air pressure in the accommodating chamber 11 the same as the external air pressure. Of course, an air pressure balance valve 34 can also be provided on the vent pipe to balance the air pressure inside and outside the filter tank 1.

[0053] like Figure 2 As shown, in some embodiments of the utility model, the activated carbon separation device also includes a third gas pipeline 64, the outlet end of the third gas pipeline 64 is connected to the top of the filter tank 1 and communicates with the accommodating chamber 11, the inlet end of the third gas pipeline 64 is communicated with the first gas pipeline 6, the ninth stop valve 61 is located upstream of the inlet end of the third gas pipeline 64, and the third gas pipeline 64 is provided with an eleventh stop valve 65.

[0054] Specifically, after the sterile air providing device 66 applies a predetermined amount of air, the activated carbon is basically separated from the filter screen 22, and of course the filter screen 22 is basically rinsed clean. At this time, the second stop valve 16 is opened for drainage, and the pure water mixed with the activated carbon flows outward through the discharge pipe 15. Then the eighth stop valve 18, the tenth stop valve 63, the first stop valve 14 and the third stop valve 31 are closed, and the ninth stop valve 61 and the eleventh stop valve 65 are opened at the same time. The sterile air providing device 66 inputs air into the accommodating chamber 11 through the first gas pipeline 6 and the third gas pipeline 64. The air will apply pressure to the pure water mixed with the activated carbon, so that the pure water is discharged faster.

[0055] like Figure 2 As shown, in some embodiments of the utility model, a plurality of sprayers 7 for washing the inner side of the filter screen 22 are further provided in the accommodating chamber 11, and the sprayers 7 are connected to the top of the filter tank 1 and are located above the filter screen 22.

[0056] Specifically, after all the pure water in the filter tank 1 is discharged, the twelfth stop valve 72 and the thirteenth stop valve 74 can be opened, and the CIP cleaning device 75 delivers pure water to the sprayer 7 through the second cleaning pipeline 71, and all the sprayers 7 can spray water to the inner side of the filter screen 22, thereby further flushing all the inner sides of the filter screen 22. The water used to flush the filter screen 22 can be returned to the CIP cleaning device 75 through the cleaning liquid recovery pipe for recovery. The CIP (Clean in Place) cleaning device 75 is a conventional device in the field, and the present utility model does not elaborate on its structure and principle. Preferably, the sprayer 7 can be a rotating cleaning ball or a high-pressure nozzle, etc.

[0057] In some embodiments, a liquid level sensor 33 is further provided on the discharge pipe 15. In some embodiments, a flow meter 32 is further provided on the liquid outlet pipeline 3.
