Embodiment 1

[0026] refer to figure 1 with 2 , the perlite filter element of the present embodiment is circular tube shape, and the whole filter element is formed by one-time processing of perlite and a certain proportion of kaolin, and its specific manufacturing process is as follows:

[0027] (1) Raw ore crushing: Perlite raw ore is a solid shale-like ore, which is collected by the mine and stored in a centralized manner. The collected perlite raw ore is sent to a crusher for crushing to obtain pearls with a particle size of 0.05-0.2 mm rock powder;

[0028] (2) High-temperature firing: The perlite powder obtained in step (1) is fired at a high temperature at 800-1000°C to expand the perlite powder;

[0029] (3) Grinding: send the perlite powder fired and expanded in step (2) into a grinder for grinding until the particle size is

[0030] (4) Sieving: Sieve the perlite powder after step (3), and take the perlite powder with a particle size between 0.001 and 0.01 mm for us...

Abstract

The invention relates to a production method of a pearlite filter element. The production method comprises the following steps of crushing pearlite raw ore, sintering at a high temperature, grinding, screening, mixing with kaolin, carrying out injection mold and knockout, carrying out sintering in a tunnel furnace, carrying out finish machining, and carrying out examination and warehousing. The production method of the pearlite filter element has the advantages that processing steps are less; construction is simple; two inorganic mineral matters of pearlite and kaolin are utilized as main materials of the pearlite filter element so that costs are low and the purposes of environmental protection and health are realized; pearlite can produce high void fraction in pearlite filter cake forming and there are a large amount of capillary interstices among particles so that the pearlite filter element can catch ultramicro particles having sizes below 1 micrometer and ideal filtration effects are obtained; and the pearlite filter element obtained by the production method does not contain any organic matter, has heavy metal ion content of 0.005ppm and is subjected to disinfection in high-temperature sintering and thus the pearlite filter element can be utilized for food filtration, especially, is suitable for drinking water filtration, and can replace an organic polymer material filter element commonly adopted by the existing household water dispenser.

Description

technical field [0001] The invention relates to a production method of a perlite filter core. Background technique [0002] Perlite is a glassy rock formed by the rapid cooling of acidic lava from volcanic eruptions. It is named for its pearly fissure structure. The main components of perlite are potassium, sodium and aluminum silicate. Its particles are irregular curly flakes with high porosity. There are many capillary pores between each particle. Therefore, perlite is widely used in filters, Catalysts, molecular sieves, and thermal insulation materials are often used as carriers for rubber, fertilizers, and pesticides. [0003] At present, the filter elements used in household water dispensers are generally composed of PP (polypropylene) filter shells and activated carbon filled in the PP filter shells. This filter element uses refractory and non-renewable organic polymer PP materials as the filter shell or On the one hand, the filter membrane is not environmentally fri...
