Description

Technical Field

[0001] This utility model belongs to the technical field of reverse osmosis membrane filtration devices, specifically relating to a reverse osmosis membrane filtration device that is easy to assemble. Background Technology

[0002] Reverse osmosis membrane filtration is a highly efficient water treatment device widely used in seawater desalination, industrial pure water production, and drinking water purification. Its core component is the reverse osmosis membrane (RO membrane), which separates water molecules from dissolved impurities through pressure. Most water purification measures utilize reverse osmosis membrane filtration devices. The reverse osmosis membrane effectively removes microorganisms, dissolved salts, heavy metals, and other impurities and pollutants from water, converting most wastewater or seawater into pure water. Compared to traditional water treatment processes, reverse osmosis technology has lower operating costs because it does not require large amounts of chemical reagents and energy. When high-concentration brine and low-concentration pure water are separated by a semi-permeable membrane, water molecules spontaneously diffuse from the pure water side to the brine side until the osmotic pressure on both sides reaches equilibrium. A pressure higher than the osmotic pressure is then applied to the brine side, forcing water molecules to flow backward through the membrane pores. Dissolved salts, organic matter, colloids, microorganisms, and other impurities are retained, thus purifying the water.

[0003] Currently, existing reverse osmosis membrane filtration devices typically require the filter element to be installed inside the housing during use, and then reverse osmosis filtration is achieved using the internal filter element. However, the filter element in traditional reverse osmosis membrane filtration devices often requires the use of small parts such as screws and nuts for fixing during assembly. This assembly method is not only troublesome, time-consuming, and labor-intensive, but also increases the difficulty of installation, thus affecting the assembly efficiency of the staff and reducing the ease of assembling the reverse osmosis membrane filtration device. Utility Model Content

[0004] The purpose of this invention is to provide a reverse osmosis membrane filtration device that is easy to assemble. This addresses the problem that existing reverse osmosis membrane filtration devices typically require the filter element to be installed inside the housing for reverse osmosis filtration. However, the assembly of filter elements in traditional reverse osmosis membrane filtration devices often requires the use of small parts such as screws and nuts for fixing. This assembly method is not only cumbersome and time-consuming, but also increases the difficulty of installation, thus affecting the assembly efficiency of workers and reducing the ease of assembling the reverse osmosis membrane filtration device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reverse osmosis membrane filtration device that is easy to assemble, comprising a housing, a top cover fixedly connected to the top of the housing, a filter element penetrating through the top of the top cover, a connecting plate threadedly connected to the top of the filter element, an inlet pipe connected to the outer wall of the housing, and an outlet pipe connected to the bottom of the housing.

[0006] Two fixing blocks are symmetrically distributed on the top of the connecting plate. Limiting slots are formed on the outer walls of the two fixing blocks. Two mounting seats are symmetrically distributed on the top of the top cover. A bidirectional lead screw is inserted through one end of the two mounting seats. Two threaded connecting blocks are threaded to the outer walls of the bidirectional lead screw. An L-shaped limiting plug is fixedly connected to the top of the two threaded connecting blocks.

[0007] As a preferred embodiment of the reverse osmosis membrane filtration device of this utility model, which is easy to assemble, a guide rod is fixedly connected inside the mounting base, and the end of the threaded connecting block is sleeved on the outer wall of the guide rod.

[0008] As a preferred embodiment of the reverse osmosis membrane filtration device of this utility model that is easy to assemble, the end of the L-shaped limiting block away from the threaded connecting block is adapted to the size of the limiting slot.

[0009] As a preferred embodiment of the reverse osmosis membrane filtration device of this utility model that is easy to assemble, the through end of the bidirectional lead screw is connected to the inner wall of the mounting base through a bearing to form a rotating connection structure.

[0010] As a preferred embodiment of the reverse osmosis membrane filtration device of this utility model that is easy to assemble, the top of the top cover is provided with an annular sealing groove, and the bottom of the connecting plate is fixedly connected with an annular protrusion.

[0011] As a preferred embodiment of the reverse osmosis membrane filtration device of this utility model that is easy to assemble, the dimensions of the annular sealing groove and the annular protrusion are adapted to each other.

[0012] As a preferred embodiment of the reverse osmosis membrane filtration device of this invention, which is easy to assemble, a sealing ring is bonded to the bottom of the annular protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By connecting the filter element to the bottom of the connecting plate with a thread, and then inserting the filter element into the housing, the fixing block will be located at the top of the mounting base. Then, by rotating the double-ended screw clockwise with the knob, the two threaded connecting blocks connected to the outer wall can drive the L-shaped limiting blocks to move towards each other until one end of the L-shaped limiting block is inserted into the limiting slot on the outer wall of the fixing block. In this way, the reverse osmosis membrane filtration device can be assembled more conveniently.

[0015] By incorporating an annular sealing groove, an annular protrusion, and a sealing ring, the filter element, once inserted into the housing, increases the contact area between the connecting plate and the top cover by embedding the annular protrusion at the bottom of the connecting plate into the annular sealing groove. Furthermore, the sealing ring, in conjunction with these features, further enhances the sealing effect at the top cover insertion port, thereby improving the overall sealing performance.

[0023] 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.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a reverse osmosis membrane filtration device that is easy to assemble, including a shell 1, a top cover 2 fixedly connected to the top of the shell 1, a filter element 3 passing through the top of the top cover 2, a connecting plate 4 threadedly connected to the top of the filter element 3, an inlet pipe 5 connected to the outer wall of the shell 1, and an outlet pipe 6 connected to the bottom of the shell 1.

[0025] Two fixing blocks 7 are symmetrically distributed on the top of the connecting plate 4. Limiting slots 8 are opened on the outer walls of the two fixing blocks 7. Two mounting seats 9 are symmetrically distributed on the top of the top cover 2. A bidirectional screw 10 is inserted through one end of the two mounting seats 9. Two threaded connecting blocks 11 are threadedly connected to the outer wall of the bidirectional screw 10. An L-shaped limiting plug 12 is fixedly connected to the top of the two threaded connecting blocks 11.

[0026] Preferably, a guide rod 13 is fixedly connected inside the mounting base 9, the end of the threaded connecting block 11 is sleeved on the outer wall of the guide rod 13, the end of the L-shaped limiting plug 12 away from the threaded connecting block 11 is adapted to the size of the limiting slot 8, and the through end of the bidirectional screw 10 forms a rotating connection structure with the inner wall of the mounting base 9 through a bearing.

[0027] In practical use, the filter element 3 is connected to the bottom of the connecting plate 4 by thread, and then the filter element 3 is inserted into the housing 1. At this time, the fixing block 7 will be located on the top of the mounting base 9. Then, the two-way screw 10 is rotated clockwise by the knob, so that the two threaded connecting blocks 11 connected to the outer wall can drive the L-shaped limiting plug 12 to move towards each other until one end of the L-shaped limiting plug 12 is inserted into the limiting slot 8 on the outer wall of the fixing block 7. Thus, the reverse osmosis membrane filtration device can be assembled more conveniently through the above method.

[0028] Conversely, by turning the double-acting screw 10 counterclockwise with the knob, the two threaded connecting blocks 11 connected to its outer wall can drive the L-shaped limiting block 12 to move in opposite directions until one end of the L-shaped limiting block 12 can be disengaged from the limiting slot 8 on the outer wall of the fixing block 7. Finally, the filter element 3 can be removed from the inside of the outer shell 1 by using the handle on the top of the connecting plate 4.

[0029] Preferably, the top of the top cover 2 is provided with an annular sealing groove 14, and the bottom of the connecting plate 4 is fixedly connected with an annular protrusion 15. The dimensions between the annular sealing groove 14 and the annular protrusion 15 are compatible, and a sealing ring 16 is bonded to the bottom of the annular protrusion 15.

[0030] In practical use, by setting up the annular sealing groove 14, the annular protrusion 15, and the sealing ring 16, when the filter element 3 is inserted into the housing 1, the contact surface between the connecting plate 4 and the top cover 2 can be increased by embedding the annular protrusion 15 at the bottom of the connecting plate 4 into the annular sealing groove 14. In addition, the sealing ring 16 can further improve the sealing effect at the insertion port of the top cover 2, thereby improving the sealing performance.

[0031] It should be noted that when the annular protrusion 15 is embedded in the annular sealing groove 14, the annular protrusion 15 will squeeze the sealing ring 16, causing it to deform. At this time, the sealing ring 16 will fill the gap. Furthermore, the adhesive surface between the annular protrusion 15 and the sealing ring 16 is made of butyl waterproof adhesive, which has the characteristics of good low-temperature flexibility, aging resistance, and long-lasting adhesion.

[0032] Working principle: First, connect the filter element 3 to the bottom of the connecting plate 4 via threads. Then, insert the filter element 3 into the housing 1. At this time, the fixing block 7 will be located on top of the mounting base 9. Then, rotate the double-ended screw 10 clockwise by turning the knob, so that the two threaded connecting blocks 11 connected to the outer wall can drive the L-shaped limiting insert 12 to move towards each other until one end of the L-shaped limiting insert 12 is inserted into the limiting slot 8 on the outer wall of the fixing block 7. Thus, the reverse osmosis membrane filtration device can be assembled more conveniently through the above method. Furthermore, through the setting of the annular sealing groove 14, the annular protrusion 15, and the sealing ring 16, when the filter element 3 is inserted into the outer wall... After entering the shell 1, by embedding the annular protrusion 15 at the bottom of the connecting plate 4 into the annular sealing groove 14, the contact area between the connecting plate 4 and the top cover 2 can be increased. In addition, the sealing effect at the insertion port of the top cover 2 can be further improved by cooperating with the sealing ring 16, thereby improving the sealing performance. Finally, by turning the knob counterclockwise the bidirectional screw 10, the two threaded connecting blocks 11 connected to the outer wall can drive the L-shaped limiting insert 12 to move in opposite directions until one end of the L-shaped limiting insert 12 can be disengaged from the limiting slot 8 on the outer wall of the fixing block 7. Finally, the filter element 3 can be taken out from the shell 1 by the handle on the top of the connecting plate 4.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
