Description

Technical Field

[0001] This utility model belongs to the field of water purifier technology, specifically relating to a high-level intelligent control hollow nanofiltration water purifier with dual membranes that can backwash and flush each other for sewage discharge. Background Technology

[0002] As an essential water purification device for modern families, water purifiers originated in the 19th century. Through multiple generations of technological innovation, such as activated carbon adsorption, ion exchange, and reverse osmosis, they have now developed into mature products that efficiently remove impurities, bacteria, heavy metals, and other pollutants from water. Their development has witnessed the continuous improvement of human beings' demand for healthy drinking water, and their application scenarios have expanded from the initial industrial water use to multiple fields such as daily household water use, business offices, and outdoor emergency use.

[0003] Currently, most water purifiers on the market have several problems, the most prominent being the need for frequent filter replacements. Spiral wound nanofiltration membrane filters, after a period of use, experience a significant decrease in water flow due to the accumulation of impurities, forcing users to replace them frequently. This not only increases user costs but also provides a poor user experience. Furthermore, existing single hollow nanofiltration membrane water purifiers typically only allow forward flushing and cannot perform backwashing, making it difficult to completely remove harmful substances from the membrane module. This easily leads to membrane clogging, further affecting the filter's lifespan and filtration efficiency. Utility Model Content

[0026] Example

[0027] Reference Figures 1-5 This embodiment of the present invention provides a high-level intelligent control hollow nanofiltration water purifier with dual membranes that can backwash and flush simultaneously, including...

[0028] The fixing mechanism 100 includes a base plate 101, a mounting plate 102 fixedly installed on the side wall of the base plate 101, and a base 103 symmetrically arranged on the side wall of the mounting plate 102.

[0029] The purification mechanism 200 includes a water pump 201 fixedly installed on the side wall of the base plate 101, a water pump pipe 202 connected to the side wall of the water pump 201, a first nanofiltration cartridge 203 fixedly installed on the side wall of the base 103, a second nanofiltration cartridge 204 fixedly installed on the outer surface of the base 103, a water inlet assembly 205 disposed on the side wall of the water pump 201, a sewage discharge assembly 206 disposed on the surface of the second nanofiltration cartridge 204, and a water outlet assembly 207 disposed on the outer surface of the first nanofiltration cartridge 203.

[0030] A water purifier, characterized in that: the water inlet assembly 205 includes a connecting pipe 205a connected to the side wall of the water pump 201, a diversion pipe 205b connected to the side wall of the connecting pipe 205a, a first normally open solenoid valve 205c connected to one end of the diversion pipe 205b, a second normally open solenoid valve 205d connected to the other end of the diversion pipe 205b, and a first water inlet pipe 205e connected to the side wall of the first normally open solenoid valve 205c.

[0031] Specifically, an inlet pressure sensor is installed at the end of the water pump 202, and a purified water pressure sensor is installed at the end of the first outlet pipe 207a. The start and stop of the water pump 201 are controlled by the two pressure sensors to provide stable pressure for the nanofiltration membrane.

[0032] The water inlet assembly 205 also includes a second water inlet pipe 205f connected to the side wall of the second normally open water inlet solenoid valve 205d, a normally closed front drain solenoid valve 205g connected to the side wall of the first water inlet pipe 205e, and a three-way drain pipe 205h connected to the side wall of the normally closed front drain solenoid valve 205g. The drain assembly 206 includes a first drain pipe 206a connected to the side wall of the first nanofiltration cartridge 203, a second drain pipe 206b connected to the side wall of the second nanofiltration cartridge 204, and a first normally closed rear drain valve 206c connected to the side wall of the second drain pipe 206b.

[0033] Furthermore, two sets of sewage discharge solenoid valves are installed, symmetrically positioned at both ends of the three-way sewage discharge pipe 205h, to control the discharge of sewage.

[0034] The sewage discharge assembly 206 also includes a second normally closed rear sewage discharge valve 206d connected to the side wall of the first sewage discharge pipe 206a, a connecting pipe 206e connected to the side wall of the second normally closed rear sewage discharge valve 206d, and a discharge pipe 206f connected to the side wall of the connecting pipe 206e. The water outlet assembly 207 includes a first water outlet pipe 207a connected to the side wall of the first nanofiltration cartridge 203, a second water outlet pipe 207b connected to the side wall of the second nanofiltration cartridge 204, a diversion pipe 207c connected to the side wall of the first water outlet pipe 207a, and a one-way valve 207d connected to the side wall of the diversion pipe 207c.

[0035] Preferably, the one-way valve 207d ensures that the purified water will not return to the first nanofiltration cartridge 203 or the second nanofiltration cartridge 204, thus ensuring the efficiency of water purification.

[0036] The water outlet assembly 207 also includes an activated carbon box 207e connected to the side wall of the one-way valve 207d, an online ultraviolet sterilization module 207f connected to the side wall of the activated carbon box 207e, and a direct drinking water pipe 207g connected to the side wall of the online ultraviolet sterilization module 207f.

[0037] Among them, the online ultraviolet sterilization module 207f can be connected to the network, which facilitates the recording and control of the sterilization process.

[0038] It should be noted that ultrafiltration membranes are also provided in the first nanofiltration cartridge 203 and the second nanofiltration cartridge 204. The pore size of the ultrafiltration membrane is between 0.01 and 0.1 micrometers, which can effectively filter pollutants such as large molecular organic matter, colloids, bacteria and viruses in the water, while retaining minerals and trace elements in the water. After the raw water enters the first nanofiltration cartridge 203 through the water pump 201 and the water pipe 202, it first undergoes preliminary filtration through the ultrafiltration membrane to remove large molecular pollutants such as suspended solids, colloids, bacteria and viruses. Subsequently, the water undergoes deep filtration through the nanofiltration membrane to remove small molecular pollutants such as heavy metal ions and organic matter.

[0039] During use, the operation of the water pump 201 is controlled by the inlet water pressure sensor and the purified water pressure sensor. The raw water first enters the first nanofiltration cartridge 203 for preliminary filtration. Part of the filtered water flows to the activated carbon box 207e for further purification. Finally, after being sterilized by the online ultraviolet lamp module, it flows out to the faucet through the drinking water pipe 207g for users to drink. By switching the corresponding inlet solenoid valve and drain solenoid valve, the water enters another nanofiltration cartridge as backwash water for backwashing. The trapped harmful substances are washed away and discharged through the drain solenoid valve. After a period of filtration, the roles of the two nanofiltration cartridges are reversed. The nanofiltration cartridge that was originally filtering becomes the one receiving backwashing, while the backwashed nanofiltration cartridge begins to filter. This cycle repeats, realizing mutual backwashing and flushing of the two membranes.

[0040] In summary, by precisely controlling the operation of the water pump 201 through the inlet water pressure sensor and the purified water pressure sensor, this water purifier system ensures that the raw water undergoes effective preliminary filtration in the first nanofiltration cartridge 203, followed by deep purification through the activated carbon box 207e and sterilization by the online ultraviolet lamp module, ultimately providing safe drinking water for users. Simultaneously, through intelligent switching of the inlet and outlet solenoid valves, the system can backwash the other nanofiltration cartridge, effectively removing trapped harmful substances and discharging them. This achieves mutual backwashing and forward flushing of the two nanofiltration cartridges. The ultrafiltration membrane further enhances the quality of the purified drinking water. This cyclical working mode not only improves the membrane's lifespan and filtration efficiency but also ensures a continuous and stable water quality output, greatly enhancing the user's drinking water safety and convenience.
