Description

Technical Field

[0001] This utility model mainly relates to the technical field of reverse osmosis nanofiltration membrane modules, specifically a reverse osmosis nanofiltration membrane module. Background Technology

[0002] With societal development and increasing water pollution, water resources are becoming increasingly scarce. Water purifiers utilizing reverse osmosis and nanofiltration membrane modules can effectively remove pollutants from water (such as mud, heavy metals, bacteria, viruses, and other harmful substances), allowing us to drink clean water. Furthermore, due to their compact size and ease of installation, more and more families, hotels, schools, and other establishments are starting to use water purifiers. Reverse osmosis and nanofiltration membrane modules are the core components of water purifiers. The water purification effect of a pure water machine is directly related to the water purification efficiency of the reverse osmosis membrane module. As consumables, they are periodically replaced in these water purifiers, leading to a growing demand for reverse osmosis and nanofiltration elements and a huge market.

[0003] A search revealed a reverse osmosis nanofiltration membrane module disclosed in publication number CN214416066U, comprising a module body with end caps at both ends. A fixing arc plate is provided at the outer end of each end cap, and fixing ears are provided at both ends of each fixing arc plate. A through hole is provided at the inner end of each fixing ear, and an adjusting threaded rod is provided at the inner end of the through hole. A threaded sleeve is provided at the outer end of the adjusting threaded rod corresponding to the right end of the through hole. An inner chamber is provided at the inner end of the module body, and a filter screen is provided at the inner end of the inner chamber. A fixing plate is provided at the front end of the filter screen, and arc-shaped retaining plates are provided at both ends of the fixing plate, with retaining grooves at both ends of the arc-shaped retaining plates. This reverse osmosis nanofiltration membrane module of the present invention is equipped with features to improve the sealing of the reverse osmosis nanofiltration membrane module and its connections, facilitating use, and includes a device for easy internal cleaning, preventing potential internal blockage.

[0004] However, the above solution still has shortcomings. The solution improves the sealing of the reverse osmosis nanofiltration membrane module and the connection by fixing the arc plate, but the fixed arc plate is prone to deformation during use and has a poor service life. During assembly, the operator still needs to repeatedly tighten the threaded sleeve, which is complicated.

[0005] Therefore, we provide a reverse osmosis nanofiltration membrane module to address the shortcomings of the above-mentioned solutions. Utility Model Content

[0006] This utility model mainly provides a reverse osmosis nanofiltration membrane module to solve the technical problems mentioned in the background art.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0008] A reverse osmosis nanofiltration membrane module includes a module body. Limiting sleeves are fixedly fitted on the upper and lower sides of the outer side of the module body. Threaded interfaces are fixedly connected to the upper and lower sides of the module body. Sealing caps are fitted on the outer sides of the two threaded interfaces. Connectors are fixedly connected to the side of the sealing caps away from the module body. Insertion holes are fixedly opened on the front and rear sides of the connector. A docking sleeve is provided on the inner side of the connector. A reinforcing sleeve is fixedly fitted on the outer side of the docking sleeve. Limiting rods are fixedly connected to both sides of the reinforcing sleeve. A reinforcement mechanism is provided on the outer side of the connector.

[0009] Furthermore, the reinforcement mechanism includes a movable cover that is movably sleeved on the outside of the connector. A circular slot is fixedly opened at the center of the top of the movable cover. Limiting slots are fixedly opened on both sides inside the movable cover. Insert rods are provided on both the front and rear sides of the movable cover. A return spring is sleeved on the outside of the insert rod. A pull plate is fixedly connected to the side of the insert rod away from the movable cover.

[0010] Furthermore, the movable cover is slidably connected to the outside of the docking sleeve through a circular slot, and a second sealing ring is provided at the contact point between the circular slot and the docking sleeve. The movable cover is also slidably connected to the limiting rods provided on both sides of the reinforcing sleeve through limiting grooves opened on both sides inside.

[0011] Furthermore, the insertion rod penetrates the movable cover and extends into the interior of the movable cover. The insertion rod is slidably connected to the movable cover at the penetration point. One side of the return spring is fixedly connected to the outer wall of the movable cover, and the other side of the return spring is fixedly connected to the pull plate. The inner side of the return spring is slidably connected to the insertion rod, and the connector is fixed to the movable cover by the insertion rod through the opened insertion hole.

[0012] Furthermore, the sealing cap is threadedly connected to the threaded interface, and a sealing ring is provided at the contact point between the sealing cap and the limiting sleeve.

[0013] Furthermore, a central tube is fixedly connected to the center of the main body of the component, and several uniformly distributed permeation holes are fixedly opened on the outside of the central tube. Several reverse osmosis membranes are fixedly sleeved inside the main body of the component and located outside the central tube in a stacked arrangement.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model, through its reinforced mechanism, allows the movable cover to slide off the connecting sleeve after the connecting sleeve is fitted with the inlet of the central tube. This allows the limiting groove inside the movable cover to align with the limiting rod. Pulling the pull plate extends the insertion rod outward, aligning it with the insertion hole. Releasing the pull plate allows the insertion rod to align with the insertion hole under the action of the return spring, thus reinforcing the connecting sleeve. Simultaneously, the second sealing ring improves the sealing degree, making the connection operation simple and disassembly convenient during use, and extending the service life of the reverse osmosis nanofiltration membrane module.

Several uniformly distributed permeation holes 102 are fixedly opened on the outside of the central tube 101. Several reverse osmosis membranes 103 are fixedly sleeved inside the component body 1 and on the outside of the central tube 101.

[0027] The specific operation method of this utility model is as follows:

[0028] First, after connecting the connecting sleeve 3 to the inlet of the central tube 101, slide the movable cover 401 off the connecting sleeve 3, so that the limiting groove 404 inside the movable cover 401 aligns with the limiting rod 302. Then, pull the pull plate 407 to extend the insertion rod 405 outward, so that the position of the insertion rod 405 aligns with the position of the insertion hole 202. Release the pull plate 407, and under the action of the return spring 406, the insertion rod 405 aligns with the insertion hole 202, thereby reinforcing the connecting sleeve 3. At the same time, the sealing ring 403 can improve the sealing degree. The docking operation is simple, the disassembly and assembly are convenient, and the service life of the reverse osmosis nanofiltration membrane module is improved. In addition, by removing the module body 1 and unscrewing the upper and lower sealing covers 2, the filter screen inside the module body 1 can be cleaned, providing convenience for the staff.
