Problems solved by technology

[0002] At present, the traditional carbon filter technology is extrusion type, the filter mainly uses granular activated carbon, the water flow is axially flowing, the adsorption area is small, and ordinary non-woven fabric is used to wrap the skeleton, which is easy to cause carbon powder to leak into the skeleton tube
At the same time, the resistance of the filter element is increased, and the water outlet speed is slow, which wastes carbon resources to a certain extent.

Embodiment Construction

[0021] Hydrophilic treatment of synthetic fiber to solve the water repellency of synthetic fiber: dilute the hydrophilic silicone oil at a ratio of 1:50, stir evenly with the synthetic fiber at a ratio of 1:8, spin dry, and put it in an infrared oven at a temperature of 90℃±5 Bake for about 2 hours.

[0022] Anti-leakage treatment on the surface of the skeleton to prevent the leakage of carbon powder: put hydrophilic synthetic fiber silk (1.5D×1.5mm) 1:6 (protective agent: water 1:50) into the slurry tank and stir evenly; The pulp tank is stirred at a constant speed, the skeleton is fixed and sucked for 5 seconds on the pressure gauge 0.05Mpa, the thickness of the silk pulp is sucked into 0.5mm, and it is suspended in an infrared oven for pre-drying (temperature 50 ° C) for about 1 hour; Silk (2.5D×3mm) 1:5 (protective agent: water 1:60) is put into another slurry tank and stirred evenly, then sent to another slurry tank with a constant speed stirring pressure gauge of 0.08Mpa...

Abstract

The present invention relates to the producing and machining field of carbon filter element, which is a manufacturing method of carbon and fabric filter element synthesized by raw and supplementary materials of absorbent charcoal, compound cellosilk, sealing ring, shell cover, cementing compound, antiseep lining, net, outer layer of the net, thermal shrinkage film and so on.The method of producing and machining of carbon and fabric filter element is provided with reasonable design, simple operation, low processing cost, and obvious energy-saving effect. The present invention can resolve the problem of framework package without cloth for preventing charcoal powder leakage, big adsorption resistance force, slow water speed.The present invention is mainly used for water utilization of municipal drinking water, food industry, industrial plating solution and so on.

Description

technical field [0001] The invention relates to the field of production and processing of carbon filter elements, in particular to a composite material synthesized from raw and auxiliary materials such as activated carbon, composite fiber filaments, adhesives, sealing rings, end caps, anti-leakage bushings, sleeve nets, outer heat shrinkable films of the sleeve nets, etc. A method for making carbon and fiber filter elements. Background technique [0002] At present, the traditional carbon filter technology is extrusion type, the filter mainly uses granular activated carbon, the water flow has an axial flow and the adsorption area is small, and the ordinary non-woven fabric is used to wrap the skeleton, which is easy to cause carbon powder to leak into the skeleton tube. At the same time, the resistance of the filter element is also increased, and the speed of water discharge is slow, which wastes carbon resources to a certain extent. SUMMARY OF THE INVENTION [0003] In o...
