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 purifying filter element based on a modified glass fiber framework. The air purifying filter element comprises a vibration sealing base, wherein a low-efficient filter element, an active carbon filter element and a HEPA (High Efficiency Particulate Air) filter element are arranged on and fixed to the vibration sealing base from outside to inside in sequence; meanwhile, the top ends of the low-efficient filter element, the active carbon filter element and the HEPA filter element are arranged on a top pressing base; the vibration sealing base and the top pressing base are fixedly connected through a positioning-connecting-fixing mechanism. According to the air purifying filter disclosed by the invention, the vibration sealing base and the top pressing base in the filter element are fixedly connected through the positioning-connecting-fixing mechanism; mounting and detachment can be realized by only rotating a positioning screw rod out and then pulling a connecting base out, and firm mounting and fixing are realized; moreover, the filter element can be mounted and detached conveniently and rapidly, and the problem of inconvenience in detaching the existing filter element during replacement is solved.

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...
