Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, specifically a reverse osmosis desalination device. Background Technology
[0002] Currently, reverse osmosis (RO) treatment devices are generally used to remove salt from water. This method can quickly separate salt from water. However, as the usage time increases, corresponding problems also arise, namely, the RO membrane in the RO treatment unit needs to be replaced more frequently. This is due to the filtration of impurities in the water, which leads to an increase in the number of replacements.
[0003] Therefore, in order to solve the aforementioned problems in existing technologies, existing equipment uses multiple RO reverse osmosis units for treatment. While this method does reduce the frequency of replacement, it significantly increases the cost. This is because impurities and other particles in the water play a crucial role in clogging. Therefore, simply adding RO reverse osmosis units cannot solve this problem; clogging and replacement will still occur over time.
[0004] Therefore, in order to overcome the above-mentioned technical problems and reduce the replacement frequency without adding RO reverse osmosis units, a reverse osmosis desalination device is proposed, which can solve the technical problems in the prior art. Utility Model Content

The baffle ring is installed within the frame structure, with a connecting column connecting the two sets of perforated plates. The lower end of the lower perforated plate contacts the upper surface of the baffle ring, and a filter membrane is installed on the upper surface of the baffle ring. The purification structure is installed on one side of the frame structure and connected to the diversion structure. Its connecting pipe 1 is connected to the water outlet of the frame structure, and the other end is connected to the water inlet of the water pump 1 installed on the frame structure. The water outlet of the water pump 1 is connected to the connecting pipe 2, which has two ports. One port is equipped with an electric butterfly valve 1, and the other port is equipped with an electric butterfly valve 2. The water outlet of the pre-purification structure is connected to the connecting pipe 3, which has two ports, and each port is connected to the pre-purification structure separately. One set of ports is connected to an electric butterfly valve 3, and the other set of ports is connected to an electric butterfly valve 4. An electric butterfly valve 5 is connected to the connecting pipe 3, and one end of the connecting pipe 3 is connected to the connecting pipe 4. The connecting pipe 4 is connected to the reverse osmosis treatment structure.
[0007] Furthermore, the reverse osmosis treatment structure includes a support structure and a treatment structure. The support structure includes a connecting pipe five, a support, a filter, and a water pump two. The support is located on one side of the frame structure. The filter and the water pump two are installed on the support and connected by a connecting pipe. The connecting pipe five is installed on the surface of the filter and connected to the connecting pipe four. The outlet end of the water pump two is connected to the connecting pipe six. Two sets of openings are located at one end of the connecting pipe six, and each set of openings is connected to the treatment structure.
[0008] Furthermore, the processing structure includes a connecting pipe six, an RO treatment pipe, a connecting pipe seven, and a drain pipe; the opening of the connecting pipe six is connected to the RO treatment pipe, the other end of the RO treatment pipe is connected to a connecting pipe eight, and is connected to two other sets of RO treatment pipes through branches on the connecting pipe eight. The other ends of the two sets of RO treatment pipes are connected to the connecting pipe seven, and the port of the connecting pipe seven is connected to the drain pipe.
[0009] As a preferred technical solution, the frame structure includes a mounting frame, a mounting plate, a base plate, a treatment tank, and an end cap; the mounting plate is installed on the upper surface of the mounting frame, the base plate is located on the bottom surface of the mounting frame, the treatment tank is installed on the mounting plate, and an end cap is installed on the upper surface of the treatment tank, wherein a retaining ring is installed on the inner side of the treatment tank, and a water pump is installed on the upper surface of the base plate.

[0011] Compared with the prior art, the present invention provides a reverse osmosis desalination device, which has the following beneficial effects:
[0012] 1. In this device, water enters the treatment tank through the connecting pipe on the end cap via a baffle ring, a perforated plate, a filter membrane, and a connecting column. The water first comes into direct contact with the filter membrane, thus performing preliminary filtration of large particles and impurities in the water. The water then falls to the bottom of the treatment tank through the perforated plate. The double-layer filtration further improves the filtration efficiency for impurities and particles in the water.
[0013] 2. This device, through the retaining ring and connecting column, allows for easy installation and replacement by simply inserting the end cap, making it convenient to replace the filter membrane on the mesh plate.

This device, connected via pipe 1, water pump 1, pipe 2, electric butterfly valve 1, electric butterfly valve 2, pipe 3, electric butterfly valve 3, electric butterfly valve 4, and electric butterfly valve 5, operates as follows: During operation, to reduce the load on the RO reverse osmosis membrane, electric butterfly valves 1, 3, and 5 are closed. At this time, only one set of filter cartridges further filters the water, reducing impurities. When the filter cartridge needs replacement due to usage time, to maintain continuous operation, electric butterfly valve 1 is opened, electric butterfly valve 2 is closed, electric butterfly valves 3 and 5 are opened, and electric butterfly valve 4 is closed, switching to another set of filter cartridges. This enables continuous water filtration, effectively reducing the load on the RO reverse osmosis membrane and decreasing the replacement frequency of the RO reverse osmosis unit.
[0015] By configuring the above structures, this device solves the problem of frequent replacement of RO reverse osmosis units in existing reverse osmosis desalination devices. Attached Figure Description
