[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 7 As shown, in one embodiment, a prefabricated guided support type seawater desalination device includes an inlet shell 1, a membrane shell 2, and a pumping assembly. The inlet shell 1 has an inlet pipe 3, and the membrane shell 2 has a drain pipe 4. The pumping assembly is used to draw external water into the inlet shell 1 through the inlet pipe 3, and then pump the water drawn into the inlet shell 1 into the membrane shell 2. The device also includes a guiding assembly, which comprises:

[0032] The first connecting pipe 5 is fixedly connected to the top of the membrane shell 2. A check valve is installed inside the first connecting pipe 5. The top of the first connecting pipe 5 is rotatably connected to the connecting pipe 6. Two guide grooves 7 are opened in the annular array inside the connecting pipe 6. The guide grooves 7 include docking grooves 701 and 701, pulling grooves 702 and limiting grooves 703.

[0033] The second connecting pipe 8 is fixedly connected to two linkage pins 9 symmetrically at the bottom end of the water inlet shell 1. The second connecting pipe 8 is inserted into the connecting pipe 6, and the two linkage pins 9 are slidably set in the two limiting grooves 703. A sealing gasket 10 is provided between the top end of the second connecting pipe 8 and the bottom end of the first connecting pipe 5.

[0034] It should be understood that the inlet shell 1 and the membrane shell 2 are connected via a guide assembly. During the connection process, the first connecting pipe 5 is rotated and adjusted so that the docking groove 701701 aligns with the linkage pin 9 on the second connecting pipe 8. Then, the connecting pipe 6 on the first connecting pipe 5 is connected to the second connecting pipe 8, so that the linkage pin 9 slides into the docking groove 701701. Then, the inlet shell 1 and the membrane shell 2 are rotated relative to each other so that the orientation of the inlet pipe 3 and the outlet pipe 4 can be adjusted relative to each other for the external pipes. Adapt the connection direction. After adjusting the direction, press and hold the water inlet shell 1 and the membrane shell 2, and rotate the connecting pipe 6. The connecting pipe 6 drives the guide groove 7 to move. During the process of pulling the groove 702 through the linkage pin 9, the linkage pin 9 will drive the second connecting pipe 8 to go deeper into the connecting pipe 6 until the limiting groove 703 moves to the linkage pin 9. The end of the second connecting pipe 8 and the end of the first connecting pipe 5 clamp the sealing gasket 10. Under the damping of the sealing gasket 10, the sealing docking is achieved, and the relative position of the water inlet shell 1 and the membrane shell 2 is positioned.

[0035] The pumping assembly includes: a pumping cover 11, which is threaded onto the surface of the first end a of the inlet housing 1, and an inlet valve connected to the inner wall of the inlet pipe 3; a pumping piston 12, which is slidably disposed on the inner wall of the inlet housing 1; and an electric cylinder 13, which is fixedly connected to the pumping cover 11, and the end of the piston rod passes through the pumping cover 11 and is fixedly connected to the pumping piston 12.

[0036] It should be understood that after the orientation of the inlet pipe 3 and the drain pipe 4 is determined, during the pumping process, the electric cylinder 13 is started. The electric cylinder 13 will push and pull the pumping piston 12 back and forth. During the process of the pumping piston 12 being pulled, water will be sucked into the inlet shell 1 through the inlet pipe 3. During the process of the pumping piston 12 being pushed, the water in the inlet shell 1 will be pushed out of the inlet shell 1. The pushed water will enter the membrane shell 2 through the first connecting pipe 5, be filtered, and then be discharged through the drain pipe 4.

[0037] It should be further explained that the inlet valve will provide a one-way seal to the inlet pipe 3, so that the water entering the inlet shell 1 cannot be discharged from the inlet pipe 3.

[0038] The check valve is used to provide a one-way seal to the first connecting pipe 5, so that the water passing through the first connecting pipe 5 cannot return to the inlet shell 1.

[0039] Both the inlet valve and the check valve include a valve seat 14 and a sealing port 15. The two valve seats 14 are fixedly connected to the inner wall of the inlet pipe 3 and the inner wall of the second connecting pipe 8, respectively. The two sealing ports 15 are fixedly connected to the inner wall of the inlet pipe 3 and the inner wall of the second connecting pipe 8, respectively. A valve stem 17 is slidably inserted into each of the two valve seats 14. A sealing piston 16 is fixedly connected to the end of each of the two valve stems 17. The two sealing pistons 16 are in contact with the two sealing ports 15, respectively. A support spring 18 is sleeved on the surface of each of the two valve stems 17. The two ends of the support spring 18 are fixedly connected to the valve seat 14 and the sealing piston 16, respectively.

[0040] It should be understood that the principle of one-way sealing is that during the water flow, as the water flow pushes the sealing piston 16, the sealing piston 16 will compress the support spring 18 and open the sealing port 15 at the same time, and the water flow will pass through the sealing port 15 to achieve flow. When the water flows in the opposite direction, it will push the sealing piston 16 to press against the sealing port 15 to achieve sealing, thereby achieving one-way sealing.

[0041] A plug-in interface 19 is provided at the second end b of the membrane housing 2. A filter element is inserted into the plug-in interface 19. A sealing cover 20 is threadedly connected to the plug-in interface 19. The end of the filter element away from the plug-in interface 19 is connected to the drain pipe 4.

[0042] It should be understood that the water entering the membrane housing 2 will be filtered by the filter element and then discharged through the drain pipe 4, thus achieving the filtration process.

[0043] It should be further explained that by setting the threaded connection between the insertion port 19 and the sealing cover 20, when the filter element needs to be replaced, the sealing cover 20 can be unscrewed, and then the filter element can be taken out and replaced again, thus realizing the replaceability of the filter element.

[0044] The filter element includes a support tube 21 and a filter layer 22. A drain outlet 23 is provided on the surface of the support tube 21. The filter layer 22 is fixedly sleeved on the surface of the support tube 21. The end of the support tube 21 away from the insertion interface 19 has a through-hole.

[0045] It should be understood that the two ends of the support tube 21 are respectively abutted against the sealing cover 20 and the membrane shell 2 to realize the installation of the filter element. The port of the support tube 21 is connected to the drain pipe 4, so that the water entering the membrane shell 2 is filtered through the filter layer 22. The filtered water enters the support tube 21 through the drain port 23. The water entering the support tube 21 will be discharged through the port and the drain pipe 4 to achieve filtration treatment.

[0046] like Figure 1 and Figure 2As shown, in one embodiment, an annular groove 24 is provided at the end of the support tube 21 away from the insertion interface 19, and a docking ring 25 that mates with the annular groove 24 is fixedly connected to the inner wall of the membrane housing 2. Through the docking of the annular groove 24 and the docking ring 25, the end of the filter element is docked with the drain pipe 4 of the membrane housing 2, that is, on the one hand, the membrane housing 2 supports the filter element, and on the other hand, it guides the connection between the drain pipe 4 and the filter element.

[0047] like Figure 1 As shown, in one embodiment, the end of the water inlet pipe 3 is threadedly connected to a water suction connector 26. The water suction connector 26 is threadedly connected to the water inlet pipe 3, which enables the water suction end to be detachable, so as to facilitate the replacement of different water suction connectors 26.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
