Embodiment 1

[0038] An air purification filter element based on a modified glass fiber skeleton, such as Figure 1-5 As shown, it includes a vibration-sealed base 1, and the vibration-sealed base 1 is sequentially installed and fixed with a coarse-effect filter element 2, an activated carbon filter element 3 and a HEPA high-efficiency filter element 4. At the same time, the coarse-effect filter element 2 and the activated carbon filter element 3 and the top of the HEPA high-efficiency filter core 4 are installed on the top pressure seat 5, and the vibration sealing base 1 and the top pressure seat 5 are connected and fixed by a positioning connection fixing mechanism 6;

[0039] The vibration-seal base 1 includes a bottom plate 11, and the surface of the bottom plate 11 is sequentially provided with a first bottom ring groove 12, a second bottom ring groove 13 and a third bottom ring groove 14; wherein the first bottom ring groove 12, the second bottom ring groove The bottom ring groove 13...

Embodiment 2

[0053] The modified glass fiber filter screen is made of modified glass fiber, and the specific preparation process of the modified glass fiber is as follows:

[0054] Step 1, add 100g of neutral polyamide resin into 4L of dimethylformamide and stir to dissolve, then add 12g of nano-titanium dioxide to it, stir and mix evenly to obtain a bonding solution; wherein 40-45mL of dimethicone is added to each gram of neutral polyamide resin In methylformamide;

[0055] Step 2: Add 120g of glass fiber to 1L of bonding solution, then add 23g of 2,3-epoxypropyltrimethylammonium chloride to it, raise the temperature to 60-70°C and ultrasonically shake for 3-4h, then drop by drop Add 33.8g of isophorone diisocyanate, ultrasonicate while adding dropwise, react at a constant temperature for 1-1.5h after the dropwise addition is complete, then cool down to room temperature, remove the glass fiber, and dry it in an oven at 40-50°C to obtain Modified glass fibers.

Abstract

The invention discloses an air purification filter element based on a modified glass fiber skeleton, which comprises a vibrating sealing base on which a coarse-effect filter element, an activated carbon filter element and a HEPA high-efficiency filter element are sequentially installed and fixed from outside to inside. The tops of the high-efficiency filter element, activated carbon filter element and HEPA high-efficiency filter element are installed on the top pressure seat, and the vibration sealing base and the top pressure seat are connected and fixed by a positioning connection fixing mechanism. The present invention realizes the connection and fixation of the vibration seal base and the top pressure seat in the filter element by setting a positioning, connection and fixing mechanism. When installing and dismounting, it is only necessary to rotate the positioning screw, and then pull out the connecting seat to realize the installation and fixing. It is more convenient and quick to install and disassemble, and solves the problem of inconvenient removal of the existing filter element during replacement.

Description

technical field [0001] The invention belongs to the field of air purification filter elements, and relates to an air purification filter element based on a modified glass fiber skeleton and a preparation method thereof. Background technique [0002] The air purification filter element is generally composed of multi-stage filter elements. Through the layer-by-layer filtration of the multi-stage filter elements, the dust particles and toxic gas substances in the air can be filtered and adsorbed, thereby improving the quality of the air. The existing filter elements usually include coarse filter elements. , activated carbon filter element and HEPA high-efficiency filter element, directly fix the three filter elements in the fixed ring one by one, because the filter element needs to be replaced frequently after a period of use, and the existing filter element is inconvenient to remove when replacing, and it is not suitable for coarse filtration. The core mainly realizes first-le...
