Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to an ultrapure liquid nanometer-level filtering core. Background Art

[0002] Nanofiltration is a new category between ultrafiltration and reverse osmosis that was innovatively invented by the cross-penetration of advanced nanotechnology and traditional filtration technology. Its separation performance depends on the nanoscale microporous structure in its active separation layer, and its separation mechanism follows the adsorption-dissolution-diffusion-filtration model. It can retain organic matter and heavy metals that can pass through ultrafiltration while passing through some of the minerals retained by reverse osmosis, allowing the concentration and salt penetration processes to proceed simultaneously, thereby achieving specific separation and purification requirements.

[0003] After the nano-scale filter element has been used for a period of time, in order to ensure the filtering effect on the water quality, it is necessary to clean or replace it regularly. During the installation of the nano-scale filter element, one end of the filter element is connected to the bottom wall of the filter cartridge through a thread. Although the convenience of installation and disassembly of the filter element is ensured, due to the long overall length of the filter element, during use, the filter element is easily vibrated and swung due to the impact of the liquid, thereby increasing the friction between the filter element and the filter cartridge, and increasing the risk of loosening or leakage at the connection. In addition, the vibration or swing of the filter element caused by the impact of the liquid will loosen the particles or impurities on the filter element, causing them to re-enter the liquid, thereby reducing the filtering effect on the liquid and making it impossible for the liquid to achieve the expected filtering accuracy.

[0004] Therefore, an ultrapure liquid nanometer filter element is urgently needed to solve the above problems. Utility Model Content

While ensuring the convenience of installation and disassembly of the filter element body 102, the firmness of the installation of the filter element body 102 is improved, thereby further ensuring the stability of the filter element body 102 during use.

[0026] It is worth noting that: as a prior art, the specific structure and working principle of the nano-scale filter element have been mastered by people in this field, and will not be elaborated here.

[0027] See also Figure 5 , a rubber protective pad is provided on the side wall of each mounting rod 205 shown in the figure;

[0028] It should be noted that: by providing a rubber protective pad on the side wall of the mounting rod 205 , damage to the fixing ring 203 caused by excessive pressing force is avoided, and at the same time, it is ensured that the mounting rod 205 can fully press against the side wall of the fixing ring 203 .

[0029] See also Figure 4 and Figure 5 The driving mechanism shown in the figure includes a driving plate 301 slidably connected in the mounting tube 202, a rotating plate 302 is rotatably connected to one side of the driving plate 301 close to each mounting rod 205, and the other end of each rotating plate 302 is connected to the mounting rod 205, and a pushing mechanism for pushing the driving plate 301 is provided on the mounting tube 202;

[0030] It should be noted here that: by setting the driving mechanism, it is convenient to make each installation rod 205 move away from or towards each other.

[0033] See also Figure 4 and Figure 5The pushing mechanism shown in the figure includes a pushing rod 5 slidably connected to the mounting tube 202, one end of the pushing rod 5 is connected to the driving plate 301, and the other end of the pushing rod 5 is set against the sealing cover 105;

[0034] It should be noted here that: by setting the pushing mechanism, it is convenient to realize the movement of each installation rod 205 away from each other through the installation of the sealing cover 105.

[0035] Working principle: When installing the filter element body 102, first align the four positioning rods 104 at one end of the filter element body 102 with the positioning holes 103 on the inner bottom wall of the filter tank 101, and insert the positioning rods 104 into the positioning holes 103. During the process of inserting the positioning rods 104 into the positioning holes 103, the mounting holes 204 on the fixing ring 203 will be inserted into the mounting tube 202 on the mounting ring 201;

[0036] Then, the sealing cover 105 is installed on the filter tank 101. During the process of installing the sealing cover 105 on the filter tank 101, the inner wall of the sealing cover 105 will abut against one end of the push rod 5, so that under the driving force, the driving plate 301 at one end of the push rod 5 will be pushed to move in the installation tube 202, further driving the rotating plate 302 to rotate. During the rotation of the rotating plate 302, each installation rod 205 will be driven to move away from each other, so that each installation rod 205 moves out of the installation tube 202 and abuts against the side wall of the fixing ring 203, so that the installation and fixation of the filter element body 102 is achieved through the abutting effect of each installation rod 205, thereby improving the firmness of the installation of the filter element body 102 by fixing and limiting the two ends of the filter element body 102, thereby further ensuring the stability of the filter element body 102 during use;

[0037] When the filter element body 102 is disassembled, when the sealing cover 105 is opened, since the push rod 5 is no longer pushed by force, the reset assembly will push the drive plate 301 to move in the opposite direction in the mounting tube 202, thereby driving the mounting rods 205 to move closer to each other, thereby releasing the pressing effect on the fixing ring 203, and further realizing the disassembly of the filter element body 102. The operation is simple and the implementation is convenient. While ensuring the convenience of installation and disassembly of the filter element body 102, the firmness of the installation of the filter element body 102 is improved, thereby further ensuring the stability of the filter element body 102 during use.
