Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis filter technology, specifically to an opener for a purified water reverse osmosis filter. Background Technology

[0002] Reverse osmosis (RO) filters play a crucial role in water treatment, especially in applications requiring high-purity water, such as pharmaceuticals, electronics, and laboratories. Their primary function is to remove dissolved salts, heavy metals, organic matter, and microorganisms from water using a high-performance RO membrane, significantly improving water purity. The extremely small pore size of the RO membrane effectively blocks bacteria and viruses, ensuring the water meets sterility standards. The basic structure of an RO filter includes the RO membrane, a pretreatment system, a pressure vessel, a high-pressure pump, and a water recovery system. The pretreatment system removes large particulate impurities, extending the RO membrane's lifespan; the high-pressure pump provides sufficient pressure for the water to pass through the RO membrane. The water quality monitoring system monitors the dissolved solids content in the water in real time, ensuring the produced water meets standards. In some demanding applications, a single-stage RO filter may not meet the water quality requirements; therefore, multiple RO filters are often used in series. Using multiple reverse osmosis filters in series allows for different levels of water treatment. The pre-stage RO system removes most impurities, while the post-stage RO system performs more refined treatment. However, after multiple reverse osmosis filters are used in series for an extended period, the RO membranes inside some filter housings need to be replaced in a timely manner. Because the reverse osmosis filters are connected in series, that is, adjacent filters are connected together by pipes, operators must disconnect the pipe connections of each filter one by one to remove the reverse osmosis filter during maintenance and replacement. This is not only time-consuming and labor-intensive, but also easily leads to extended system downtime. In addition, since the reverse osmosis filters are located in relatively concealed locations and the filtration equipment is usually installed in a relatively small space, operators also need to disassemble some parts or equipment when replacing the membrane, which further increases the complexity of maintenance operations. Utility Model Content

[0003] The purpose of this invention is to provide an opener for a reverse osmosis filter for purified water. A flip cover is installed on the top of the upper sealing shell of the filter housing. The flip cover is locked to the upper sealing shell by a bolted positioning structure. When it is necessary to replace the reverse osmosis filter element, the flip cover is released and opened, and the connection between the conical inlet head and the double-threaded inlet head of the reverse osmosis filter element is disconnected. Thus, the reverse osmosis filter element can be taken out of the housing and replaced with a new filter element without disconnecting the connection between the reverse osmosis filters, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an opener for a reverse osmosis filter for purified water, comprising a filter housing and an upper sealing shell threadedly fitted at the top opening of the filter housing. The left and right outer walls of the upper sealing shell are respectively provided with a drain port and a double-threaded inlet head. A flip cover is hinged to the top of the upper sealing shell, and a lower sealing plate is installed at the bottom of the flip cover. The lower sealing plate and the top opening of the upper sealing shell are interlocked. Bolted positioning structures for connecting to the top of the upper sealing shell are provided on both outer walls of the flip cover. A conical inlet head is fixed to the top of the reverse osmosis filter element, and a right-angle connector for maintaining a unidirectional flow with the double-threaded inlet head is installed at the top of the conical inlet head.

[0005] Preferably, two symmetrical supports are fixed on one side of the top of the upper sealing shell, and a connecting arm is installed between the two supports through a hinge shaft. One end of the connecting arm is fixedly connected to one side of the outer wall of the flip cover.

[0006] Preferably, the lower sealing plate is made of a rubber component.

[0007] Preferably, the outer circumferential surface of the lower sealing plate is inlaid with two sealing rings.

[0008] Preferably, the bolted positioning structure includes a rectangular protrusion integrally formed on the outer wall of one side of the flip cover and a positioning bolt installed inside the rectangular protrusion. The top of the upper sealing shell is provided with an internally threaded countersunk hole that extends downward and is concentric with the positioning bolt.

[0009] Preferably, the top of the flip cover is provided with a plurality of intersecting reinforcing ribs.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This opener for a reverse osmosis filter for purified water achieves efficient, convenient, and safe filter element replacement by combining components such as a filter housing, reverse osmosis filter element, right-angle connector, upper sealing shell, double-threaded inlet head, flip cover, and bolted positioning structure. The flip cover design allows operators to quickly access the filter element, reducing maintenance time and labor costs. The opening and locking mechanism of the flip cover makes the filter element replacement process intuitive and simple, reducing operational difficulty. Especially in situations with limited space, the flip cover design effectively reduces the workload of operators. Furthermore, the flip cover design allows filter element replacement without disassembling the entire filter, greatly shortening downtime. Operators can complete filter element replacement in a short time, ensuring the continuous operation of the water treatment system and reducing economic losses caused by downtime.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 An embodiment of this utility model is provided: an opener for a reverse osmosis filter for purified water, including a filter housing 1 and an upper sealing shell 3 threadedly assembled at the top opening of the filter housing 1. The left and right outer walls of the upper sealing shell 3 are respectively provided with a drain port 4 and a double-threaded inlet head 5. The top of the upper sealing shell 3 is hinged with a flip cover 6. The top of the flip cover 6 is provided with several intersecting reinforcing ribs. The bottom of the flip cover 6 is installed with a lower sealing plate 7, which is made of rubber.

[0019] The lower sealing plate 7 and the upper sealing shell 3 are interlocked at their top openings. The outer walls on both sides of the flip cover 6 are provided with bolted positioning structures 8 for connecting with the top of the upper sealing shell 3. The top of the reverse osmosis filter element 2 is fixed with a conical inlet head 9. The top of the conical inlet head 9 is equipped with a right-angle connector 10 for maintaining a one-way passage with the double-threaded inlet head 5.

[0020] When disconnecting the right-angle connector 10 and the double-threaded inlet head 5, the operator needs to rotate the nut between the right-angle connector 10 and the double-threaded inlet head 5 so that the nut is turned toward the conical inlet head 9 until the nut is no longer connected to the conical inlet head 9 and the double-threaded inlet head 5, thereby disconnecting the passage between the reverse osmosis filter element 2 and the double-threaded inlet head 5.

[0021] Two symmetrical supports 301 are fixed on one side of the top of the upper sealing shell 3. A connecting arm 601 is installed between the two supports 301 through a hinge shaft. One end of the connecting arm 601 is fixedly connected to the outer wall of one side of the flip cover 6. When the flip cover 6 is flipped upward, the flip cover 6 deflects around the support 301 through the connecting arm 601 and the hinge shaft, so that the flip cover 6 can be flipped up or down. The design of the flip cover 6 not only makes the filter element replacement operation convenient, but also prevents external pollutants from entering the filter.

[0022] Two sealing rings 701 are embedded on the outer circumferential surface of the lower sealing plate 7. After the lower sealing plate 7 is embedded into the interior of the upper sealing shell 3, the two sealing rings 701 on the outer circumferential surface of the lower sealing plate 7 play a sealing role, so that the outer wall of the lower sealing plate 7 and the inner wall of the upper sealing shell 3 are in closer contact, so as to prevent water from seeping out of the filter housing 1 and the upper sealing shell 3.

[0023] The bolted positioning structure 8 includes a rectangular protrusion 801 integrally formed on one side of the outer wall of the flip cover 6 and a positioning bolt 802 installed inside the rectangular protrusion 801. The top of the upper sealing shell 3 is provided with a downwardly extending internal thread countersunk hole that is concentric with the positioning bolt 802. The positioning bolt 802 passes through the rectangular protrusion 801 and is screwed into the interior of the upper sealing shell 3, thereby fixing the flip cover 6 and the lower sealing plate 7. It can firmly fix the flip cover 6 during operation and ensure that the flip cover 6 is not accidentally opened during daily use.

[0024] In this embodiment, the operator first needs to confirm that the purified water reverse osmosis filtration equipment is in the off state and close the switch valves connected to the inlet and outlet pipes of the filter. Then, the operator releases the restriction of the bolted positioning structure 8 on the flip cover 6 so that the flip cover 6 can be flipped up freely. The operator can flip the flip cover 6 up relatively easily, exposing the inside of the filter to the greatest extent. At this time, the top of the upper sealing shell 3 has a circular opening due to the removal of the flip cover 6 and the lower sealing plate 7. The operator then needs to disconnect the conical inlet head 9 of the reverse osmosis filter element 2 from the double-threaded inlet head 5. To disconnect the right-angle connector 10 and the double-threaded inlet head 5, the double-threaded inlet head 5 and the reverse osmosis filter element 2 are no longer physically connected. After disconnecting the reverse osmosis filter element 2, the operator can easily remove the old reverse osmosis filter element 2 by slightly shaking or pulling it out of the filter housing 1. Then, remove the new filter element, ensuring that it matches the specifications of the original filter element, and install it into the filter housing 1 in the reverse order, connecting the double-threaded inlet head 5 and the right-angle connector 10. Finally, lower and lock the flip cover 6.
