Abstract

The invention provides a manufacturing method of an air purification filter cartridge device, and the air purification filter cartridge device is manufactured by a filter element and a partition plate. The shape of that filter element is a cylindrical structure formed by crimping a trapezoid with a narrow upper part and a wide lower part. The filter element is prepared from a composite fiber material prepared from glass fiber and a titanium dioxide-cobalt oxide sol. The filter element is provided with multiple layers, and the adjacent layers are separated by aluminum platinum material spacers.In the manufacturing method of the air purification filter cartridge device designed by the invention, the filter element is prepared from the composite fiber material prepared from the titanium dioxide-cobalt oxide sol and a glass fiber gel, and organic matters are rapidly degraded through adsorption of the composite fiber. The material catalyzes the degradation of harmful organic substances under the condition of no light, and the reaction rate is faster than that of a photocatalyst. The composite fiber prepared by the method has the advantages of good transparency, high stability, good product dispersibility, high transparency, no by-products, firm bonding of the glass fiber, and capability of resisting multiple attacks of wind speed and flow rate.

Example Embodiment

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Such as figure 1 As shown, an air purification filter cartridge device, the air purification filter cartridge device is made of a filter element and a spacer; the shape of the filter element is a trapezoid with a narrow top and a wide bottom and a cylindrical structure made by crimping; the filter element The composite fiber material is made of glass fiber and titanium dioxide-cobalt oxide sol; the filter element is arranged with multiple layers, and the adjacent layers are separated by spacers of aluminum platinum material.

[0024] The preparation process of an air purification filter cartridge device is as follows:

[0025] Fabrication of filter element: make titanium dioxide-cobalt oxide sol and glass fiber gel rubber blank; draft and calender the titanium dioxide-cobalt oxide sol and glass fiber gel rubber blank to obtain composite fibers; dry the composite fibers; cut according to the required shape .

[0026] In the above process, the manufacturing process of titanium dioxide-cobalt oxide sol and glass fiber gel blank is as follows:

[0027] Add water and dispersant to the titania-cobalt oxide sol and glass fiber gel to dissociate them into a mortar; transport the mortar and white water solution to the mixing tank for stirring and slag removal treatment, the solid content of the slurry Controlled at 0.5% (weight), viscosity controlled at 15CP, PH controlled at 8;

[0028] The uniformly stirred mixed slurry is transported to the filter core of the twin-wire squeezer for papermaking, the thickness is controlled to 2.2mm, and the paperwork is vacuum suctioned to remove water and pressed to obtain a rubber green.

[0029] However, the drying process includes the following steps: the composite fiber enters the oven for drying, the center temperature of the oven is 360°C, the oven inlet and the oven outlet are semi-closed, and the temperature in the entire oven shows the characteristics of high middle and low sides according to the length direction. The time is controlled at 30min.

[0030] After drying, the composite fiber is cut into a trapezoid shape with a narrow top and a wide bottom to make a filter element.

[0031] In order to make the connection between the separator and the filter element tight, the separator has a structure that is crimped into a cylindrical shape with ribs and grooves.

[0032] The present invention designs a method for manufacturing an air purification filter cartridge device. A composite fiber material prepared from titanium dioxide-cobalt oxide sol and glass fiber gel is used to make a filter element, and organic matter is rapidly degraded through the adsorption of the composite fiber. The material catalyzes the degradation of harmful organic matter under the condition of no light, and the reaction rate is faster than that of photocatalyst. The composite fiber prepared by the invention has good transparency, high stability, good product dispersion, high transparency, no by-products, and high product purity. The service life is long, the glass fiber is firmly bonded, and it can resist multiple attacks of wind speed and flow.

[0033] It has been verified that the air purification filter cartridge device can maintain a purification rate of more than 80% when the cumulative purification amount of volatile organic compounds, such as formaldehyde, benzene, ether esters, trichloroethylene, acrylonitrile, etc. reaches 15mg/ml.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
