[0040] The utility model discloses a water treatment cleaning device, which includes a cleaning tank 10, a drug adding component 20, a filter component 30 and a first pipeline 40. The cleaning tank 10 is provided with a first water inlet 11 and a first water outlet 12; the drug adding component 20 is communicated with the first water inlet 11, and the drug adding component 20 is used to add cleaning agent into the cleaning tank 10; the filter component 30 is provided with a second water inlet 33 and a second water outlet 34, the first water outlet 12 is communicated with the second water inlet 33, and the cleaning tank 10 is used to pass water added with cleaning agent into the filter component 30 to perform a first cleaning on the filter component 30; one end of the first pipeline 40 is connected to the second water outlet 34, and the other end is connected to the accident pool 120, so as to discharge the waste liquid after the first cleaning into the accident pool 120.

[0041] The filtration assembly 30 specifically includes a UF membrane and a RO membrane. The surfaces of the UF membrane and the RO membrane are densely covered with many tiny micropores, which only allow water and small molecules to pass through. When the raw liquid flows through the membrane surface under a certain pressure, it flows out from the liquid outlet side to form a clean permeate, and the impurities in the permeate are filtered by the UF membrane and the RO membrane. The substances in the raw liquid whose volume is larger than the micropore diameter of the membrane surface are retained on the liquid inlet side of the membrane and become concentrated liquid, thereby purifying the raw liquid.

[0042] The filter assembly 30 includes a housing, a UF membrane and a RO membrane are arranged in the housing, and the housing is divided into two accommodating chambers. The first accommodating chamber is used to accommodate the concentrated liquid, and the second accommodating chamber is used to accommodate the permeated liquid. The second water outlet 34 and the second water inlet 33 are both arranged to communicate with the first accommodating chamber.

[0043] In one embodiment, the cleaning agent may be, for example, a strong acid agent or a strong alkali agent, and the cleaning agent is stored in the agent adding component 20. When the filter component 30 needs to be cleaned, the agent adding component 20 is controlled to add the cleaning agent to the cleaning tank 10. First, one of the strong acid agent and the strong alkali agent is added to the cleaning tank 10 to form a strong acid cleaning solution or a strong alkali cleaning solution.

[0044] A water pump may be provided on the pipeline between the cleaning tank 10 and the first water inlet 11 to press the cleaning solution in the cleaning tank 10 into the filter assembly 30. The pressure of the water pump is adjusted so that the cleaning solution flushes the UF membrane and the RO membrane of the filter assembly 30. The waste liquid after flushing is temporarily stored in the first accommodation chamber.

[0045] After cleaning, the waste liquid stored in the first accommodating chamber is discharged into the accident pool 120 through the first pipeline 40. Similarly, another water pump can be installed on the first pipeline 40 to discharge the waste liquid in the first accommodating chamber from the first pipeline 40 into the accident pool 120 through the water pump.

[0046] In this embodiment, according to different cleaning requirements, after the strong acid cleaning solution or the strong alkali cleaning solution is cleaned, clean water is added to the cleaning tank 10 again, and another cleaning agent is added to the cleaning tank 10 to form a cleaning solution. The step of pressing the cleaning solution in the cleaning tank 10 into the filter assembly 30 is repeated to complete the first cleaning of the filter assembly 30.

[0047] In this embodiment, the cleaning solution is directly discharged into the accident pool 120 after cleaning, and no longer returns to the cleaning tank 10, so as to avoid the cleaning solution in the cleaning tank 10 circulating and reducing the cleaning effect.

[0048] It should be noted that the cleaning order of the strong acid cleaning solution and the strong alkaline cleaning solution can be interchanged.

[0049] In another embodiment, to improve the cleaning effect, after the strong acid or strong alkali cleaning solution is cleaned, the filter assembly 30 is cleaned a second time with clean water before adding another cleaning solution, thereby preventing the residual strong acid cleaning solution from affecting the subsequently added strong alkali cleaning solution.

[0050] Specifically, the water treatment and cleaning device also includes a water production pool 50 and a second pipeline 60. The filter component 30 also has a third water outlet 35, and the third water outlet 35 is connected to the water production pool 50. The water production pool 50 is used to collect the clean water filtered by the filter component 30; one end of the second pipeline 60 is connected to the water production pool 50, and the other end is connected to the second water inlet 33, so as to pass the filtered clean water into the filter component 30 to clean the filter component 30 for the second time; the first pipeline 40 is also used to discharge the waste liquid after the second cleaning into the accident pool 120.

[0051] The third water outlet 35 is connected to the second accommodating chamber, and the permeate is pressed into the water production pool 50 through the third water outlet 35. The water production pool 50 is used to store the permeate filtered by the filter assembly 30. The permeate is clean water. In this embodiment, after the first cleaning is completed, the clean water in the water production pool 50 is pressed into the filter assembly 30 through the second pipeline 60 from the water production pool 50.

[0052] In this embodiment, another water pump may be installed on the second pipeline 60, and the water pump is used to press clean water into the filter assembly 30. The UF membrane or RO membrane is cleaned for the second time by clean water, thereby removing the residual strong acid cleaning solution.

[0053] It should be noted that after the second cleaning, a strong alkaline cleaning solution is introduced into the filter component 30 for cleaning. After the strong alkaline cleaning solution is cleaned, clean water is introduced again for cleaning to prevent the residual strong alkaline cleaning solution after the cleaning from affecting the subsequent filtering effect.

[0054] The technical solution of the utility model realizes automatic dispensing by automatically adding cleaning agent to the cleaning tank 10 through the drug adding component 20, without manual contact. In addition, the water added with cleaning agent in the cleaning tank 10 is passed to the filter component 30 to rinse the filter component 30, and the waste water after rinsing is recovered to the accident pool 120 through the first pipeline 40. The entire cleaning process is automated and the cleaning efficiency is improved.

[0055] In another embodiment, the water treatment cleaning device also includes a first regulating valve 70, i.e., a controller, and the first regulating valve 70 is arranged on the first pipeline; the controller is electrically connected to the first regulating valve 70 and the drug adding component 20, respectively, and the controller is used to control the drug adding component 20 to add cleaning agent to the cleaning tank 10; the controller is also used to control the first regulating valve 70 to open for a first preset time and then close the first regulating valve 70 after the cleaning agent is added to the cleaning tank 10.

[0056] The medicine adding component 20 can be a reagent needle, etc., and the flow of the medicine adding component 20 can be controlled by the controller, thereby controlling the dosage of the strong acid agent. In addition, by controlling the opening or closing of the first regulating valve 70, the cleaning tank 10 and the filter component 30 are connected, and the cleaning solution is used to rinse the filter component 30.

[0057] In this embodiment, before cleaning, the cleanliness of the UF membrane and the RO membrane can be graded according to the historical cleaning records, and the dosage of the strong acid or strong alkali agent added can be determined according to the different cleanliness levels, as well as the ratio with the clean water in the cleaning tank 10, the cleaning time, etc.

[0058] According to the historical records, the medicine adding component 20 is controlled to add the corresponding medicine dosage, and the opening time of the first regulating valve 70 is controlled, so as to control the flushing time of the filter component 30 by the cleaning tank 10, that is, the first regulating valve 70 is controlled to open for the first preset time. In this embodiment, the controller is used to automatically query the medicine dosage, control the medicine adding component 20 to automatically add medicine, and control the flushing time to ensure thorough cleaning and improve the cleaning effect. The whole process is automatic, without manual intervention, and improves the cleaning efficiency.

[0059] In another embodiment, the water treatment and cleaning device also includes a second regulating valve 80, which is arranged on the second pipeline 60, and the controller is electrically connected to the second regulating valve 80. The controller is also used to control the second regulating valve 80 to open for a second preset time and then close the second regulating valve 80 after the first regulating valve 70 is closed.

[0060] In order to ensure that the residual strong acid or strong alkali cleaning agent is completely removed, after the strong acid or strong alkali cleaning agent is completed, the first regulating valve 70 is closed and the second regulating valve 80 is opened at the same time to connect the water production pool 50 with the second water inlet 33, and the filter component 30 is cleaned with clean water.

[0061] In the above process, the second regulating valve 80 can also be controlled to open for a second preset time according to historical cleaning records and for different cleaning degrees. The capacity of clean water required for flushing the filter component 30 can be indirectly controlled according to the second preset time of the second regulating valve 80 opening to ensure that residual cleaning agents are completely removed.

[0062] In another embodiment, the drug adding component 20 includes a first drug adding container 21 and a second drug adding container 22, wherein the first drug adding container 21 is provided with a first drug adding piece; the second drug adding container 22 is provided with a second drug adding piece; the controller is electrically connected to the first drug adding piece and the second drug adding piece respectively, and the controller is used to control the additive amount of the first drug adding piece and the second drug adding piece.

[0063] One of the first addition container 21 and the second addition container 22 is used to store a strong acid cleaning agent, and the other is used to store a strong alkali cleaning agent. The addition container can be, for example, a reagent needle. The amount of the reagent needle added can be automatically controlled by a controller, and this technology is a conventional technical solution and will not be repeated here.

[0065] After cleaning, the raw liquid can be filtered through the filter assembly 30, and the filtered concentrated water is discharged into the concentrated water tank 90 through the third pipeline 100. It does not need to be discharged into the accident tank 120, thereby reducing the processing pressure of the accident tank 120.

[0066] In another embodiment, the water treatment and cleaning device further includes a detection member 110, and the detection member 110 is disposed in the concentrated water tank, and the detection member 110 is used to detect environmental parameters of wastewater in the concentrated water tank.

Specifically, the detection element 110 is one or more of a pH value detector, a COD detector, a phosphorus content detector, or an ammonia nitrogen detector. By detecting the environmental parameters of the concentrated water in the concentrated water tank 90, it is determined whether there is still cleaning solvent remaining in the filter assembly 30, or whether the flushing effect is up to standard, according to the detection results.

[0068] When there is residual cleaning solvent or the cleaning does not meet the standards, an external alarm device, such as a buzzer, alarm light, etc., can be used to remind the on-site operator to handle it in time.

[0069] In another embodiment, the cleaning tank 10 is further provided with a drain hole 13, and the drain hole 13 is connected to the accident tank 120. After cleaning is completed, the remaining cleaning solution in the cleaning tank 10 is discharged into the accident tank for processing, so as to avoid the cleaning solution affecting other types of subsequent cleaning solvents.
