[0034] First embodiment

[0035] Please refer to Figure 1The present embodiment provides a continuous activated carbon filtering device, comprising a first-stage filter 1, a middle-stage filter 2 and a final-stage filter 3 which are sequentially connected in series; a large-particle activated carbon filler 104 is arranged in the first-stage filter 1, and a small-mesh filter 103 is arranged between the large-particle activated carbon filler 104 and the discharge port 109 of the first-stage filter; a medium-particle activated carbon filler 204 is arranged in the middle-stage filter 2, and a medium-mesh filter 203 is arranged between the medium-particle activated carbon filler 204 and the discharge port 209 of the middle-stage filter; a small-particle activated carbon filler 304 is arranged in the final-stage filter 3, and a large-mesh filter 303 is arranged between the small-particle activated carbon filler 304 and the discharge port 309 of the final-stage filter.

[0036] The present embodiment provides a continuous activated carbon filtering device, wherein a first-stage filter 1, a middle-stage filter 2 and a final-stage filter 3 are connected in sequence. Specifically, the material to be filtered enters the first-stage filter 1 from the feed port of the first-stage filter 1, passes through the large-particle activated carbon filler 104 and the small-mesh filter 103 in sequence, and then leaves from the first discharge port of the first-stage filter 1; the first discharge port of the first-stage filter 1 is connected to the feed port of the middle-stage filter 2 through a first connecting pipe 205, and the material to be filtered is transferred to the middle-stage filter 2, and passes through the medium-particle activated carbon filler 204 and the medium-mesh filter 203 in sequence, and then leaves from the second discharge port of the middle-stage filter 2; the second discharge port of the middle-stage filter 2 is connected to the feed port of the final-stage filter 3 through a second connecting pipe 305, and the material to be filtered is transferred to the final-stage filter 3, and passes through the small-particle activated carbon filler 304 and the large-mesh filter 303 in sequence, and then leaves from the third discharge port of the final-stage filter 3 to complete the filtration.

[0037] It should be noted that the first-stage filter 1, the intermediate filter 2 and the final filter 3 in the present application may refer to one filter or a filter group, and the specific number of filters may be set as needed.

[0038] In an optional embodiment, a first-stage feed pipe 105 is provided on the feed port of the first-stage filter 1 , and a first valve 4 , a first flow meter 5 , a first pressure sensor 6 and a feed pump 7 are provided on the first-stage feed pipe 105 .

[0039] In this embodiment, the first valve 4 is provided to control the filtering efficiency of the filtering device, and the flow meter is provided to improve the accuracy of flow control. The feeding speed of the feeding pump 7 is adjusted by the feedback of the flow meter and the pressure sensor, which is conducive to ensuring the stable operation of the equipment and the stability of the quality of the filtered material. A first pressure sensor 6 is also provided on the primary feeding pipe 105. When the pressure in the first pressure sensor 6 increases abnormally, it may be that the device is blocked and needs to be cleaned or unblocked.

[0040] It should be noted that each valve in the present application can be a start valve, which is convenient for remote control through PLC; the feed pump 7 can be frequency-controlled and can be automatically adjusted according to flow meter feedback through PLC.

[0041] In an optional embodiment, a discharge pipe is provided on the discharge port 309 of the final filter, and a second valve 8, a second flow meter 9 and a second pressure sensor 10 are provided on the discharge pipe.

[0042] In this embodiment, a second flow meter 9 and a second pressure sensor 10 are provided. When the flow rate in the second flow meter 9 is less than the flow rate in the first flow meter 5, the pressure in the device will increase, which may indicate that the device is clogged and needs to be cleaned or unblocked.

[0043] In an optional embodiment, the feed end of the first-stage filter 1 is provided with a first cleaning port 107, the first cleaning port 107 is provided with a first washing liquid feed pipe 105, and the first washing liquid feed pipe 105 is provided with a fourth valve 106; the discharge end of the first-stage filter 1 is provided with a first sewage outlet 102, the first sewage outlet 102 is provided with a first sewage outlet pipe, and the first sewage outlet pipe is provided with a third valve 101.

[0044] After the device has been running for a period of time, a lot of impurities are adsorbed in each filter, and the filters at each level can be cleaned regularly. Specifically, during cleaning, the cleaning liquid can be passed from the first cleaning port 107 into the first-stage filter 1 to desorb and clean the large-particle activated carbon filler.

[0045] It should be noted that the filters at each level can be cleaned regularly during the operation of the device, and the device can also be cleaned when the device is clogged or tends to be clogged.

[0046] In an optional embodiment, the feed end of the intermediate filter 2 is provided with a second cleaning port 207, the second cleaning port 207 is provided with a second washing liquid feed pipe 105, and the second washing liquid feed pipe 105 is provided with a sixth valve 206; the discharge end of the intermediate filter 2 is provided with a second sewage outlet 202, the second sewage outlet 202 is provided with a second sewage outlet pipe, and the second sewage outlet pipe is provided with a fifth valve 201, and the specific cleaning method is the same as the cleaning method of the first-stage filter 1.

[0047] In an optional embodiment, the feed end of the final filter 3 is provided with a third cleaning port 307, the third cleaning port 307 is provided with a third washing liquid feed pipe 105, and the third washing liquid feed pipe 105 is provided with an eighth valve 306; the discharge end of the final filter 3 is provided with a third sewage outlet 302, the third sewage outlet 302 is provided with a third sewage pipe, and the third sewage pipe is provided with a seventh valve 301, and the specific cleaning method is the same as the cleaning method of the first-stage filter 1.

[0048] It should be noted that due to the different particle sizes of activated carbon fillers in each level of filters, the optimal cleaning time for each level of filters may also be different. Each level of filter is equipped with a separate cleaning port and sewage outlet, which allows for more flexible selection of cleaning timing.

[0049] In an optional embodiment, the particle size of the large-particle activated carbon filler 104 is larger than 10 mesh, the particle size of the medium-particle activated carbon filler 204 is 20-40 mesh, and the particle size of the small-particle activated carbon filler 304 is smaller than 80 mesh.

[0050] The reasonable selection of the activated carbon particle size in each level of filter enables the filtering device in the present application to take into account both filtering effect and efficiency and reduce the clogging frequency.

[0051] In an optional embodiment, the mesh size of the small-mesh filter 103 is smaller than the minimum particle size of the large-particle activated carbon filler 104 and larger than the maximum particle size of the medium-particle activated carbon filler 204;

[0052] The mesh size of the medium mesh filter 203 is smaller than the minimum particle size of the medium particle size activated carbon filler 204 and larger than the maximum particle size of the small particle size activated carbon filler 304;

[0053] The mesh size of the large-mesh filter 303 is smaller than the minimum particle size of the small-particle activated carbon filler 304 .

[0054] The filter screens in each level of filters are mainly used to prevent the loss of activated carbon filler, so the size of the mesh aperture mainly depends on the particle size of the activated carbon filler.

[0055] In an optional embodiment, in the first-stage filter 1, the intermediate filter 2 and the final filter 3, the end close to the feed inlet is the feed end, and the end close to the discharge port is the discharge end;

[0056] Furthermore, in the first-stage filter 1 , the middle-stage filter 2 and the final-stage filter 3 , the feed ends are all located below the corresponding discharge ends.

[0057] In each level of filters, the feed end is located below the discharge end, so that the materials in each level of filters enter from the bottom and leave from the top. The material pressure and the gravity of the activated carbon act in opposite directions, which can not only make the material and the activated carbon fully mixed so that the impurities can be fully adsorbed, and the adsorption capacity of the activated carbon can be fully utilized in a graded manner, but also effectively prevent the activated carbon from sticking to and clogging the filter; it can be automatically cleaned for subsequent use, which can improve production efficiency and control product quality.

[0058] In a second aspect, the utility model provides a Chinese medicine processing device, comprising the continuous activated carbon filtering device described in any one of the aforementioned embodiments.

[0059] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
