[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 One embodiment provided by this utility model:

[0026] The intelligent multi-unit reversing reverse osmosis filter cleaning device includes a clean water tank 5, which stores the clean water used for cleaning. The clean water tank 5 is connected to multiple multi-unit membrane housings 1 through pipelines. The multi-unit membrane housings 1 are used to store the RO membrane filter elements that need to be cleaned. The multiple multi-unit membrane housings 1 are connected to a four-way reversing valve 2 through pipelines. The four-way reversing valve 2 is used to control the flow direction of the cleaning solution for reciprocating rinsing. The four-way reversing valve 2 is connected to a high-pressure water pump 3 through pipelines. The high-pressure water pump 3 is used to provide the pressure required for rinsing. The high-pressure water pump 3 is connected to a chemical solution tank 6 through pipelines. The chemical solution tank 6 is used to store the cleaning solution.

[0027] The four-way reversing valve 2 is connected to a PLC program control system 4 via an electrical circuit. The PLC program control system 4 controls the working status of the four-way reversing valve 2 and the high-pressure water pump 3. The PLC program control system 4 is connected to the high-pressure water pump 3 via an electrical circuit. The four-way reversing valve 2 is connected to the medicine tank 6 via a pipeline.

[0028] Specifically, the intelligent multi-unit reversing reverse osmosis filter cleaning device in this application is a multi-unit device that can automatically reverse direction and automatically control the time. When in use, such as... Figure 1As shown, when the chemical solution in the chemical tank 6 is pumped by the high-pressure water pump 3 through the four-way reversing valve 2 into the multi-unit membrane housing 1, the RO membrane filter element is cleaned through the chemical reaction and physical flushing of the chemical solution, thereby realizing the basic cleaning function and water production detection function of this application. According to the set time, the PLC program control system 4 changes the direction of the four-way reversing valve 2, thereby realizing the cleaning of the RO membrane filter element. Figure 1 The operating mode in the middle becomes Figure 2 In the operation mode, after the four-way reversing valve 2 is controlled by the PLC program control system 4 to reverse, the flow direction of the liquid medicine changes, realizing the function of reciprocating flushing. When the properties of the liquid medicine no longer change, a water production test is performed. This process can be repeated. The process of the PLC program control system 4 changing the direction of the four-way reversing valve 2 is as follows: Figure 3 As shown.

[0029] Working principle: In the initial state, the purified water tank 5 contains purified water for cleaning, the chemical solution tank 6 contains cleaning solution, and the multi-unit membrane housing 1 contains the RO membrane filter element to be cleaned. When forward cleaning begins, as... Figure 1 As shown, the PLC program control system 4 controls the four-way directional valve 2 to be in the position of Figure 3 As shown on the left, the medicine solution in the medicine tank 6, under the action of the high-pressure water pump 3, passes through the four-way reversing valve 2 and enters the multi-unit membrane housing 1 to clean the RO membrane filter element. The medicine solution undergoes a chemical reaction on the surface of the RO membrane filter element, while the pressure provided by the high-pressure water pump 3 physically flushes it, thus cleaning the RO membrane filter element. After a set time, reverse cleaning is performed. The PLC program control system 4 changes the direction of the four-way reversing valve 2, as shown... Figure 2 As shown, the flow direction of the liquid medicine is changed, and it enters the multi-unit membrane housing 1 from the opposite direction to backwash the RO membrane filter. When the properties of the liquid medicine no longer change, a water production test is performed to check whether the water production function of the RO membrane filter has been restored after cleaning. If the water production function does not achieve the expected effect, the above cleaning process can be repeated until the water production function of the RO membrane filter returns to normal.
