Description

Technical Field

[0001] This utility model belongs to the field of ultrapure water filtration, and specifically relates to an ultrapure water filter. Background Technology

[0002] A water purifier, also known as a reverse osmosis system, is a water purification device that removes impurities from water using filtration methods such as reverse osmosis, purifying ordinary household water into drinkable water. The water produced by a water purifier is called pure water. A water purifier is a device that filters raw water using internationally popular methods such as reverse osmosis, producing pure water without adding any compounds. It is mainly divided into two categories: drinking water purifiers and laboratory water purifiers.

[0003] According to Chinese Patent No. CN218306515U, an ultrapure water filtration device is disclosed, belonging to the technical field of filtration devices. This ultrapure water filtration device includes a water tank assembly and a filtration assembly. The water tank assembly includes a water tank body, a control valve, a flow guide column, a water injection pipe, and a flow guide pipe. The control valve is fixedly connected inside the water tank body, the flow guide column is fixedly connected inside the control valve, the water injection pipe is fixedly connected to the upper end of the water tank body, and one end of the flow guide pipe is fixedly connected to the bottom end of the water tank body. The filtration assembly includes a shell, a collection component, a filter element, a motor, a scraper, and a water outlet pipe. The collection component is fixedly connected inside the shell, the filter element is fixedly connected inside the collection component, the motor is fixedly connected inside the flow guide column, the motor is driven and connected to the scraper, the scraper is infinitely close to the inner wall of the filter element, and the water outlet pipe is fixedly connected to the bottom end of the collection component.

[0004] As can be seen from the above structure, the operator uses the control valve to obtain water from the water tank. The water in the tank enters the filter element evenly through the guide column. At the same time, the motor is turned on, and the motor drives the scraper to rotate. The filter element filters the water and then flows into the collection device. The water in the collection device finally flows out from the outlet pipe to obtain ultrapure water. However, as can be seen from the above diagrams, the traditional pure water machine filtration mechanism has low filtration efficiency. The internal filter layer is prone to decreasing filtration efficiency over a long period of use, which will result in a slow water flow rate and inconvenience in use. At the same time, it is particularly inconvenient to clean the filter tank, thus reducing the practicality of the device. Utility Model Content

[0014] In summary, the present invention has the following main advantages:

[0015] First, this utility model, through its cleaning component, uses an inlet pipe to deliver water to be filtered into the filter mesh assembly. When the water enters, it drives the drive blades to rotate, which in turn drives the drive shaft and connecting shaft to rotate. This rotation of the connecting shaft causes the connecting plate to rotate, which in turn causes the cleaning plate to rotate. The cleaning plate has cleaning brushes on its outer side, and these brushes are movably connected to the inner side of the filter mesh assembly. This allows the cleaning plate to clean the filter mesh assembly under the action of the cleaning brushes, thus preventing impurities from adhering to the surface of the filter mesh assembly and reducing filtration efficiency.

[0016] Secondly, when the filtration of water needs to be stopped, the first solenoid valve is closed and the second solenoid valve is opened, preventing water from entering the filter screen. At this time, the impurities cleaned by the cleaning brush will move downwards under the action of gravity, allowing them to enter the connecting pipe, the water inlet chamber, and then the storage tank for storage. This enables the storage and collection of impurities, thereby increasing the practicality of the device. Furthermore, automatic cleaning reduces the need for frequent maintenance by the user, thus increasing the overall practicality of the equipment. Attached Figure Description

When the first solenoid valve 8 is closed and the second solenoid valve 9 is open, impurities enter the connecting pipe 5, the water inlet chamber 6, and then enter the storage tank 12 for storage, thereby enabling the storage and collection of impurities and increasing the practicality of the device.

[0026] refer to Figure 2 and Figure 4 The lower end of the feed pipe 10 is inserted into the upper end of the storage tank 12.

[0030] refer to Figure 5The filter assembly 2 includes a mounting base 221 located on the upper end of the mounting plate 1. An ultrafiltration filter 222 is fixedly connected to the upper end of the mounting base 221, and an activated carbon filter 223 is fixedly connected to the upper end of the mounting base 221 outside the ultrafiltration filter 222. The ultrafiltration filter element uses a polypropylene hollow fiber membrane with a pore size typically of 0.01 micrometers, effectively removing suspended solids, colloids, bacteria, and other large molecules while retaining beneficial minerals in the water. The filtration efficiency is as high as 99.99%. Furthermore, the ultrafiltration membrane has a strong ability to remove colloidal impurities and viruses, and indirectly removes some dissolved organic matter through adsorption. The activated carbon filter has a significant effect on water filtration. According to multiple pieces of evidence, the activated carbon filter, through its high porosity and adsorption capacity, can effectively remove pollutants such as odors, organic matter, colloids, iron, and residual chlorine from water, thereby improving water quality. In addition, the activated carbon filter can also reduce the chemical oxygen demand (COD) in water, increase water transparency, and reduce color.

[0031] Operating principle and advantages: First, the outer casing 3 is placed on the upper end of the mounting plate 1 using the mounting screws 17. Then, the mounting screws 17 are inserted into the mounting plate 1 through the mounting screw holes, thus installing the outer casing 3. After installation, the water to be filtered is transported to the interior of the filter screen assembly 2 through the water inlet pipe 7. When the water enters, it drives the drive blades 233 to rotate. The rotation of the drive blades 233 drives the drive shaft 232 and the connecting shaft 234 to rotate. This rotation of the connecting shaft 234 causes the connecting plate 235 to rotate, which in turn causes the cleaning plate 236 to rotate. The cleaning plate 236 has cleaning brushes on its outer side, and the brushes are movably connected to the inner side of the filter screen assembly 2. Thus, the rotation of the cleaning plate 236, combined with the action of the cleaning brushes, effectively cleans the filter screen assembly, thereby preventing impurities from entering. When impurities adhere to the surface of the filter mesh group 2, causing a decrease in filtration efficiency, the cleaned water, after being tested by the water quality testing equipment 20, will be discharged through the outlet pipe 4. When it is necessary to stop filtration, the first solenoid valve 8 is closed and the second solenoid valve 9 is opened, preventing water from entering the filter mesh group 2. At this time, the impurities cleaned by the cleaning brush will move downwards under the action of gravity, allowing them to enter the connecting pipe 5, the water inlet chamber 6, and then the storage tank 12 for storage. This allows for the storage and collection of impurities, thereby increasing the practicality of the device. The upper sealing block 18, upper sealing groove 19, lower sealing block 13, and lower sealing groove 14 enhance the sealing performance of the device during use, thus preventing water leakage and ensuring the device can function properly.
