However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments. Embodiment 1

[0029] Refer toFigures 1-5 , which is the first embodiment of the present utility model. This embodiment provides a reverse osmosis composite filtration device, including,

[0030] A filtration assembly 100, which includes a bracket 101, a liquid supply pipe 102 installed on one side of the bracket 101, a liquid pump 103 installed on one side of the lower end of the bracket 101, and a filter pipe 104 installed at the middle position of the bracket 101. The liquid inlet of the liquid pump 103 is communicated with one end of the liquid supply pipe 102, and the liquid outlet of the liquid pump 103 is communicated with the liquid inlet of the filter pipe 104 through a pipeline;

[0031] An adjustment assembly 200, which includes an outer tube 201, an inner tube 202 sleeved inside the end of the outer tube 201, a main filter element 203 installed inside the outer tube 201, and a secondary filter element 204 installed on the side wall of the inner tube 202. The outer tube 201 is fixed at the middle position of the bracket 101 through a pipe clamp, and the outer tube 201 is communicated with the liquid outlet of the filter pipe 104 through a pipeline.

[0032] Among them, a liquid supply pipe 102 is installed on the bracket 101 to provide the liquid to be filtered, which is transported to the inside of the filter pipe 104 by the cooperation of the liquid pump 103 for preliminary filtration treatment. A filter element adapted to the currently transported liquid is installed inside the filter pipe 104, and the liquid pump 103 provides the pressure for transportation to perform filtration and maintain the liquid filtration efficiency. An adjustment assembly 200 is added to the side wall of the bracket 101 for further filtering the liquid. The outer tube 201 is connected and communicated with the filter pipe 104 through a pipeline, and the liquid processed by the filter pipe 104 is secondarily filtered through the main filter element 203 of the semi-permeable membrane. The filtered liquid enters the inner tube 202 equipped with the secondary filter element 204 for further filtration treatment to improve the filtration efficiency. And it is convenient to adjust the extended distance of the inner tube 202 along the outer tube 201, thereby adjusting the internal space of the outer tube 201 to adapt to different usage requirements. Actively compressing the inner tube 202 inward can reduce the internal space of the outer tube 201, causing the liquid inside the outer tube 201 to be pressurized and more quickly pressed into the inner tube 202 for filtration, enabling the liquid to be more fully filtered and reducing liquid residue.

[0033] Specifically, a connector 205 is hermetically installed on the side wall of the outer tube 201. The inside of the connector 205 is communicated with the outer tube 201, and a collection box 206 is threadedly connected to the bottom of the connector 205.

[0034] Among them, when the connector 205 with the collection box 206 is installed on the side wall of the outer tube 201, when the inner tube 202 moves towards the end of the outer tube 201, the impurities accumulated inside the outer tube 201 will be pushed towards one end, causing the impurities to enter the collection box 206 through the connector 205 for collection.

[0035] Further, a handle bolt 211 is threadedly connected to the side wall of the connecting member 205, and the end of the handle bolt 211 is in contact with the outer side wall of the outer tube 201.

[0036] Among them, installing the handle bolt 211 on the side wall of the connecting member 205 to dock with the outer tube 201, loosening the handle bolt 211 facilitates rotating and adjusting the inclination angle of the connecting member 205 on the side wall of the outer tube 201, adapting to disassembling and maintaining the aggregate box 206 at the bottom of the connecting member 205 at different positions, and preventing the aggregate box 206 from getting stuck.

[0037] Further, a connecting rod 207 is installed at the end of the inner tube 202, and a drain pipe is installed at the end of the inner tube 202 on one side of the connecting rod 207.

[0038] Among them, installing the connecting rod 207 at the end of the inner tube 202 and applying force to the connecting rod 207 can actively adjust the position of the inner tube 202, thereby changing the combined length of the inner tube 202 and the outer tube 201, adapting to different usage requirements, and facilitating adjustment.

[0039] Preferably, a fixing plate is installed on one side of the bracket 101, and a cylinder 208 is bolt - connected to the middle position of the fixing plate on the side wall of the bracket 101. The main shaft end of the cylinder 208 is fixedly connected to the end of the connecting rod 207.

[0040] Among them, installing the cylinder 208 at one end of the bracket 101 to dock with the connecting rod 207, and driving the cylinder 208 to operate by the control device in cooperation with the solenoid valve, can drive the connecting rod 207 to move on the basis of the installation of the fixing plate on the side wall of the bracket 101, adjust the position of the inner tube 202, and adjust the filtering space inside the outer tube 201.

[0041] Preferably, a panel 209 is bolt - connected to one side of the bracket 101. Pressure valves 210 are installed at equal intervals in the middle of the panel 209. One group of pressure valves 210 is connected to the outer tube 201 through a pipeline, one group of pressure valves 210 is connected to the liquid supply pipe 102 through a pipeline, and another group of pressure valves 210 is connected to the side wall of the liquid outlet of the liquid pump 103 through a pipeline.

[0042] Among them, installing the panel 209 with pressure valves 210 on the side wall of the bracket 101 facilitates observing the current pressure inside the pipeline from the panel 209, can timely adjust the operating state of the pipeline, and ensure the stable operation of the filtering device.

[0043] It should be noted that a valve 105 is installed in the middle of the liquid supply pipe 102, and the valve 105 is located between the liquid supply pipe 102 and the liquid pump 103.

[0044] Among them, installing the valve 105 in the middle of the liquid supply pipe 102 can adjust the opening and closing state of the liquid supply pipe 102. Closing the liquid supply pipe 102 through the valve 105 during shutdown can prevent the filtrate from flowing back.

[0045] In summary, a liquid supply pipe 102 is installed on the bracket 101 to supply the liquid to be filtered. It is transported to the inside of the filter pipe 104 by cooperating with the liquid pump 103 for preliminary filtration treatment. A filter element adapted to the currently transported liquid is installed inside the filter pipe 104. The liquid pump 103 provides the pressure for transportation to conduct filtration and maintain the liquid filtration efficiency. An adjustment assembly 200 is added to the side wall of the bracket 101 for further filtration of the liquid. The outer pipe 201 is connected and communicated with the filter pipe 104 through a pipeline. The liquid processed by the filter pipe 104 is secondarily filtered through the main filter element 203 of the semi-permeable membrane. The filtered liquid enters the inner pipe 202 equipped with the secondary filter element 204 for further filtration treatment to improve the filtration efficiency. Moreover, it is convenient to adjust the extended distance of the inner pipe 202 along the outer pipe 201, thereby adjusting the internal space of the outer pipe 201 to adapt to different usage requirements. Actively compressing the inner pipe 202 inward can reduce the internal space of the outer pipe 201, causing the liquid inside the outer pipe 201 to be pressurized and more quickly pressed into the inner pipe 202 for filtration, enabling the liquid to be more fully filtered and reducing liquid residue. A connecting piece 205 with an aggregate box 206 is installed on the side wall of the outer pipe 201. When the inner pipe 202 moves towards the end of the outer pipe 201, the impurities accumulated inside the outer pipe 201 will be pushed towards one end, causing the impurities to enter the aggregate box 206 through the connecting piece 205 for collection. A valve 105 is installed in the middle of the liquid supply pipe 102, which can adjust the opening and closing state of the liquid supply pipe 102. Closing the liquid supply pipe 102 through the valve 105 during shutdown can prevent the filtrate from flowing back.
