[0029] A medicament cleaning module of a schematic ship membrane treatment device, with reference to Figures 1 to 3 A medicament cleaning module of a ship membrane treatment device according to a preferred embodiment of the present application comprises a fresh water pipe 10, a sludge bin 20, a filter module 30 and a medicament bin 40.
[0030] Specifically, as Figures 1 to 3As shown in
[0031] More specifically, in the embodiment of the present application, as shown in Figure 1 and Figure 2 As shown in
[0032] In addition, as shown in Figure 1 and Figure 3 As shown in
[0033] In addition, as shown in Figures 1 to 3 As shown in
[0034] In addition, as shown in Figure 1 and Figure 3 As shown in
[0035] In addition, as shown in Figures 1 to 3As shown, the medicament cleaning module of the ship membrane treatment device further comprises a drainage main pipe 601, a plurality of drainage branch pipes 602 and a sludge feeding pipe 80, the drainage main pipe 601 communicates with each of the drainage branch pipes 602, one of the drainage branch pipes 602 communicates with the medicament bin 40, another of the drainage branch pipes 602 communicates with the sludge bin 20, still another of the drainage branch pipes 602 communicates with the circulation pipe 302, and the drainage branch pipe 602 communicating with the circulation pipe 302 further communicates with the sludge feeding pipe 80, each of the drainage branch pipes 602 is provided with a fourth valve 6021, the other end of the sludge feeding pipe 80 communicates with the sludge bin 20, and the sludge feeding pipe 80 is provided with a fifth valve 801.
[0036] It needs to be explained that when more pollutants are deposited on the cylindrical filter membrane in the filter cartridge 303, the operator can open the fourth valve 6021 on the drainage branch pipe 602 communicated with the circulating pipe 302 to realize the emptying of the sewage in the circulating pipe 302, and then the external pump body can inject fresh water into the main pipe part 101 of the fresh water pipe 10, and then according to the nature of the pollutants deposited on the cylindrical filter membrane, the alkali or acid in the basic cavity 402 or the acidic cavity 401 can be injected into the main pipe part 101 through the dosing pump 403, and the previously injected fresh water is made into an alkaline solution or an acidic solution. It needs to be supplemented that at this time, the first valve 1021 on the branch part 102 communicated with the sludge bin 20 is in a cut-off state, and the first valve 1021 on the other branch part 102 is in an open state, and then the solution flows into the circulating pipe 302 along the remaining branch part 102; in addition, when the external pump body injects fresh water into the fresh water pipe 10, the second valve 501 on the sewage inflow pipe 50 is in a cut-off state, that is, at this moment, the external sewage does not flow into the circulating pipe 302, only the acidic or alkaline solution flows into the circulating pipe 302, after a predetermined time, the circulating pump 301 is allowed to work, and the third valve on the clear water outflow pipe 3032, the fourth valve 6021 on the drainage branch pipe 602 communicated with the circulating pipe 302, and the fifth valve 801 on the sludge feeding pipe 80 are all in a cut-off state, so that the alkaline or acidic solution always circulates in the circulating pipe 302, and the pollutants attached to the cylindrical filter membrane are washed and flushed, realizing the cleaning of the cylindrical filter membrane, which is helpful to quickly restore the membrane flux of the membrane body. After a predetermined time, by opening the fourth valve 6021 on the drainage branch pipe 602 communicated with the circulating pipe 302, and the alkali or acid in the basic cavity 402 or the acidic cavity 401 is no longer injected into the main pipe part 101 through the dosing pump 403, the alkaline or acidic solution in the circulating pipe 302 will flow to the drainage main pipe 601 along the drainage branch pipe 602, realizing the emptying of the solution in the circulating pipe 302. It is easy to see that compared with the prior art, the fresh water pipe 10 and the medicament bin 40 are arranged to realize the advantages of cleaning the membrane body and helping to quickly restore the membrane flux of the membrane body.In addition, when a large amount of sludge is stored in the sludge bin 20, in order to avoid the sludge being too thick, causing the pipeline to be blocked when the sludge is transported to the external pressure filtration module, the operator can make the first valve 1021 on the branch 102 in communication with the circulating pipe 302 in a closed state, and make the first valve 1021 on the branch 102 in communication with the sludge bin 20 in an open state. Then, as the clean water continuously flows along the branch 102 to the sludge bin 20, the sludge in the sludge bin 20 can be diluted, which helps to reduce the viscosity of the sludge in the sludge bin 20, so as to achieve the technical purpose of preventing the pipeline from being blocked.
[0037] Further, if there is gas in the circulating pipe 302, the gas in the circulating pipe 302 or the circulating pump 301 will be damaged. Therefore, in the embodiment of the present application, as shown in Figure 2 and Figure 3 The medicament cleaning module of the ship membrane treatment equipment further includes an exhaust pipe 70, both ends of the exhaust pipe 70 are in communication with the drain main pipe 601 and the circulating pipe 302, and the exhaust pipe 70 is provided with a pneumatic valve 701. By arranging the pneumatic valve 701, when the alkaline chamber 402 or the acidic chamber 401 injects alkaline substances or acidic substances into the main pipe 101 through the dosing pump 403, the pneumatic valve 701 is opened and exhaust is realized. After a predetermined time, the pneumatic valve 701 is closed, and the other end of the exhaust pipe 70 is in communication with the drain main pipe 601.
[0038] It should be further pointed out that the drain branch pipe 602 in communication with the medicament bin 40 can be used to discharge the substances in the acidic chamber 401 or the alkaline chamber 402, and the drain branch pipe 602 connected with the sludge feeding pipe 80. When the filter module 30 produces water, the clean water flows along the clean water outlet 3031 to the clean water outlet pipe 3032, the sludge is discharged to the sludge feeding pipe 80 along the drain branch pipe 602 connected with the sludge feeding pipe 80, and finally flows to the sludge bin 20.
[0039] Further, the branch 102, the exhaust pipe 70, the sewage inflow pipe 50, and the drain branch pipe 602 are all in communication with the circulating pipe 302. In the embodiment of the present application, as shown in Figure 1 and Figure 3As shown, the circulation pipe 302 includes a straight pipe 3021, a U-shaped pipe 3022 and an L-shaped pipe 3023, the U-shaped pipe 3022 is located between the straight pipe 3021 and the L-shaped pipe 3023, the number of the filter cartridges 303 is two, the two filter cartridges 303 are communicated through the U-shaped pipe 3022, one filter cartridge 303 is communicated with the water inlet of the circulating pump 301 through the straight pipe 3021 away from one end of the U-shaped pipe 3022, and the other filter cartridge 303 is communicated with the water outlet of the circulating pump 301 through the L-shaped pipe 3023 away from one end of the U-shaped pipe 3022.
[0040] In addition, one end of the exhaust pipe 70 is communicated with the L-shaped pipe 3023, one end of the sewage inflow pipe 50 is communicated with the straight pipe 3021, one of the sewage branch pipes 602 communicated with the sludge feeding pipe 80 is communicated with the U-shaped pipe 3022, and one branch part 102 is communicated with the straight pipe 3021.
[0041] In summary, the medicament cleaning module of the ship membrane treatment equipment based on the embodiment of the present application is illustrated, which provides the medicament cleaning module of the ship membrane treatment equipment with the advantages of being capable of cleaning the membrane body, helping to quickly restore the membrane flux of the membrane body, diluting the sludge in the sludge bin, preventing pipeline blockage and the like.
[0042] It is worth mentioning that, in the embodiment of the present application, the medicament cleaning module of the ship membrane treatment equipment has simple structure, does not involve complex manufacturing process and expensive materials, and has high economy. At the same time, for the manufacturer, the medicament cleaning module of the ship membrane treatment equipment provided by the present application is easy to produce and has low cost, which is more conducive to controlling the production cost, and further conducive to product promotion and use.
