Embodiment 1

[0039] An activated carbon ceramic integrated filter element is composed of raw materials with the following mass fractions:

[0040] Activated carbon 40%, diatomaceous earth 30%, kaolin 20%, clay 5% and loess 5%.

[0041] The preparation method comprises the following steps:

[0042] 1) stir

[0043] Mix all raw materials, add water and stir for 30 minutes, water accounts for 35% of raw material mass;

[0044] 2) Practicing mud

[0045] The slurry that step (1) is stirred is compressed through the mud refining machine, is placed in the clamp of compressor and is cut to cut with the length of 20cm, and cuts into cylindrical shape;

[0046] 3) Natural drying

[0047] Step (2) cylindrical carbon rod is carried out natural drying for 24 hours, obtains semi-finished product;

[0048] 4) cutting

[0049] After cutting the semi-finished product obtained in step (3) into a suitable size according to the filter element specifications, use compressed air to remove the foreign mat...

Embodiment 2

[0055] The raw materials and preparation method of Example 2 are the same as those of Example 1, the only difference is that the molding temperature is different, see Table 1 for details.

Embodiment 3

[0057] An activated carbon ceramic integrated filter element is composed of raw materials with the following mass fractions:

[0058] Activated carbon 30%, diatomaceous earth 30%, kaolin 30%, clay 5% and loess 5%.

[0059] The preparation method comprises the following steps:

[0060] 1) stir

[0061] Mix all raw materials, add water and stir for 30 minutes, water accounts for 35% of raw material mass;

[0062] 2) Practicing mud

[0063] The slurry that step (1) is stirred is compressed through the mud refining machine, is placed in the clamp of compressor and is cut to cut with the length of 20cm;

[0064] 3) Natural drying

[0065] Step (2) cylindrical carbon rod is carried out natural drying for 24 hours, obtains semi-finished product;

[0066] 4) cutting

[0067] After cutting the semi-finished product obtained in step (3) into a suitable size according to the filter element specifications, use compressed air to remove the foreign matter adhered to the surface of the...

Abstract

The invention relates to a ceramic filter element, in particular to an activated carbon and ceramic integrated filter element and a preparation method thereof. The activated carbon and ceramic integrated filter element comprises raw materials in percentage by mass as follows: 20%-50% of activated carbon, 20%-40% of diatomaceous earth, 20%-40% of kaolin, 2%-5% of clay and 2%-5% of loess. The activated carbon and ceramic integrated filter element solves the problem that the conventional ceramic filter element cannot remove residual chlorine and improves water taste, one filter element capable of realizing multiple effects is produced integrally from the activated carbon and ceramic, the water purification performance is improved, and the quantity of water purification filter elements is reduced, so that a water purification system is simplified; the problem of oxidation of the activated carbon when the conventional activated carbon and ceramic are formed at a high temperature is solved; the invention further provides the preparation method of the activated carbon and ceramic integrated filter element, a process is simplified, and the production cost is reduced greatly.

Description

technical field [0001] The invention relates to a ceramic filter element, in particular to an activated carbon ceramic integrated filter element and a preparation method thereof. Background technique [0002] The ceramic filter element is set in the first half of the filter element of the water purifier, which plays the role of removing foreign matter and impurities in the pre-treatment, and is set in the back section to improve the taste of the water. Generally, ceramic filter elements installed on water purifiers to remove impurities such as foreign matter in tap water and rust in pipes are made of inorganic powders such as kaolin, clay, loess, and alumina. [0003] However, the ceramic filter element itself cannot remove residual chlorine in tap water. The ceramic material added to improve the taste of water increases the hydrogen ion concentration (PH) value and exceeds the standard for drinking water, and the total dissolved solids (TDS ) value increases to reduce the ...
