Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a combined pipeline high-pressure reverse osmosis membrane filtration device. Background Technology

[0002] Reverse osmosis membrane filtration is a membrane separation technology that uses pressure difference as the driving force. Its core principle is to apply external pressure to force water molecules through a semi-permeable membrane, while retaining dissolved substances, bacteria, viruses and other impurities in the water on the other side of the membrane, thereby obtaining pure water. Reverse osmosis membrane filtration technology is widely used in scientific research, medicine, food and beverage and other fields.

[0003] To extend the service life of reverse osmosis membranes, they need to be cleaned and maintained regularly. However, when assembling the equipment, the end caps and outer shells are usually fixed by threaded and flange connections. Disassembly requires the use of wrenches and other tools to separate the bolts and nuts, which is inconvenient. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown in this embodiment, a combined pipeline high-pressure reverse osmosis membrane filtration device includes an outer shell 1. Insert plates 2 are fixedly connected to the front and rear sides of the outer shell 1. A sliding groove 3 is provided on the inner wall of the outer shell 1. A first groove 4 is provided on the surface of the insert plate 2. A first spring 5 is fixedly connected to the inner wall of the first groove 4. A positioning block 6 is fixedly connected to the end of the first spring 5 away from the first groove 4. An end cap 7 is provided on the surface of the insert plate 2. A slot 8 is provided on the side of the end cap 7 near the outer shell 1. Positioning grooves 9 are provided on the upper and lower sides of the end cap 7. A slider 10 is fixedly connected to the left side of the end cap 7. A fixing groove 11 is provided on the side of the slider 10 away from the end cap 7.

[0023] By aligning the slider 10 with the slide groove 3 and pressing the end cover 7 inward, the slider 10 slides inside the slide groove 3 and the insert plate 2 slides inside the slot 8. The first spring 5 is compressed and contracted. After a certain displacement depth, the end face of the insert plate 2 contacts the inner wall of the slot 8. At this time, the positioning block 6 aligns with the positioning groove 9, and under the elastic force of the first spring 5, the positioning block 6 is engaged inside the positioning groove 9, thereby fixing the position of the outer shell 1 and the end cover 7. When disassembly is required, press the positioning block 6 inward to disengage it from the positioning groove 9, and pull the end cover 7 outward to separate the two, thus completing the disassembly.

[0024] There are two first grooves 4, the positioning block 6 is located inside the positioning groove 9, there are two end caps 7, the slider 10 is adapted to the sliding groove 3, and the fixing groove 11 adopts a hemispherical structure.

[0025] The inner wall of the outer shell 1 is provided with a second groove 12, and a second spring 13 is fixedly connected to the inner wall of the second groove 12. A ball bearing 14 is fixedly connected to the end of the second spring 13 away from the second groove 12.

[0026] By fixing the end cap 7 to the outer casing 1, the ball bearing 14 is engaged inside the fixing groove 11, thereby reinforcing the connection and ensuring the stability of the device during use. When in use, since the contact surface between the ball bearing 14 and the fixing groove 11 is arc-shaped, it can slide through the arc surface when pulled outward, thus facilitating the disassembly of the outer casing 1 and the end cap 7.

[0027] There are two second grooves 12, and the number of balls 14 corresponds to the number of the second grooves 12. The balls 14 are located inside the second grooves 12 and are adapted to the fixing grooves 11.

[0028] The end cap 7 has a drain hole 15 inside, a central tube 16 inside, a drain hole 17 in the middle of the central tube 16, and a membrane element 18 fixedly connected to the surface of the central tube 16.

[0029] The number of drain holes 17 is provided in multiple ways. The membrane element 18 is composed of a membrane sheet, an inlet grid and a product water grid. The membrane element 18 is located inside the outer shell 1.

[0030] The end cap 7 has a threaded groove 19 on the side away from the outer shell 1. A threaded sleeve 20 is threadedly connected inside the threaded groove 19. A connecting plate 21 is fixedly connected to the surface of the threaded sleeve 20. A sealing ring 22 is movably fitted onto the surface of the threaded sleeve 20.

[0031] By fitting the sealing ring 22 onto both sides of the connecting plate 21, aligning the threaded sleeve 20 with the threaded groove 19, and rotating the threaded sleeve 20, it rotates inside the end cover 7. After rotating a certain number of times, one side of the threaded sleeve 20 contacts the inner wall of the end cover 7, while the sealing ring 22 is pressed inward. This connects the other filter assembly through the threaded groove 19 and the threaded sleeve 20, thus completing the combination of the two filter assemblies and facilitating the adjustment of the overall length.

[0032] This utility model provides a combined pipeline-type high-pressure reverse osmosis membrane filtration device, the specific working principle of which is as follows:

[0033] In use, the membrane element 18 is rolled into a spiral shape, and the outer shell 1 is fitted over the membrane element 18 and the central tube 16. The slider 10 is aligned with the groove 3, and the end cap 7 is pressed inward, causing the slider 10 to slide inside the groove 3 and the insert plate 2 to slide inside the slot 8. The first spring 5 and the second spring 13 are compressed and contracted, and the positioning block 6 and the ball 14 move into the first groove 4 and the second groove 12, respectively. After a certain displacement depth, the end face of the insert plate 2 contacts the inner wall of the slot 8. At this time, the positioning block 6 aligns with the positioning groove 9, and the positioning block 6 is engaged inside the positioning groove 9 under the elastic force of the first spring 5. Under the elastic force of the second spring 13, the ball 14 is engaged. Inside the fixing groove 11, the positions of the outer shell 1 and the end cap 7 are fixed. The two filter components can be connected by the threaded groove 19 and the threaded sleeve 20 on the end cap 7, and the sealing ring 22 is used to ensure the sealing of the connection. During filtration, under pressure, the feed water enters the interior of the outer shell 1 from one end cap 7 and reaches the surface of the membrane separation layer through the feed water channel in the membrane element 18. The product water permeates through the membrane surface into the product water channel, enters the center of the membrane element 18 in a spiral direction, and is collected in the central pipe 16 through the drain hole 17. The remaining feed water concentration increases and is discharged from the drain hole 15 on the other end cap 7, thus completing the filtration of the feed water.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
