Embodiment 1

[0023] 42.5R ordinary Portland cement and coconut shell activated carbon particles (10-20 mesh) are used to prepare inorganic gelling activated carbon filter elements. The raw material ratio is as follows: activated carbon particles 60 wt%, Portland cement 40 wt%.

[0024] The preparation steps are:

[0025] (1) Ingredients: Weigh 240g activated carbon particles and 160g cement in proportion and mix them evenly.

[0026] (2) Coated granules: spray water while stirring until the cement is all wrapped on the surface of the activated carbon granules and can be kneaded into a mass by hand.

[0027] (3) Granulation: Pass all the above-mentioned wrapped particles through an 8-mesh sieve to prevent agglomeration.

[0028] (4) Injection molding: Put the activated carbon particles into the mold and vibrate and compact.

[0029] (5) Quiet curing demoulding: After the sample is formed, it is placed in a room for 24 hours and demoulded.

[0030] (6) Steaming: Put it in an autoclave at 195°C for more ...

Embodiment 2

[0033] 42.4R ordinary Portland cement and coconut shell activated carbon particles (20-60 mesh) are used to prepare inorganic gelling activated carbon filter elements. The raw materials are as follows: activated carbon particles 80 wt%, Portland cement 20 wt%.

[0034] The preparation steps are:

[0035] (1) Ingredients: Weigh 320g of activated carbon particles and 80g of cement in proportion and mix them evenly.

[0036] (2) Coated granules: spray water while stirring until the cement is all wrapped on the surface of the activated carbon granules and can be kneaded into a mass by hand.

[0037] (3) Granulation: Pass all the above-mentioned wrapped particles through an 8-mesh sieve to prevent agglomeration.

[0038] (4) Injection molding: Put the activated carbon particles into the mold and vibrate and compact.

[0039] (5) Quiet curing demoulding: After the sample is formed, it is placed in a room for 24 hours and demoulded.

Abstract

The invention relates to an inorganic gelatinous active carbon filter core and a preparation method thereof. The preparation method comprises the following steps of: coating cement on the surface of active carbon particles; performing injection molding; standing for demolding; and putting into a pressure kettle for steam curing to obtain the inorganic gelatinous active carbon filter core. According to the characteristics of high plasticity and high hydration strength at an initial cement setting period, high water permeability of the filter core can be kept while scattered active carbon particles are coated and molded. On one hand, compared with molding active carbon of an organic bonding agent, the inorganic gelatinous active carbon filter core has the advantage that the defects of toxicity and blockage holes are overcome. On the other hand, compared with sintering-molded active carbon, the inorganic gelatinous active carbon filter core has the advantages that the carbon content is high, and high-temperature treatment is not required. The preparation method has the advantages of easiness, low cost, wide application range and good market prospect, and is suitable for large-scale industrial production.

Description

Technical field [0001] The invention belongs to the field of activated carbon filter element materials for water purifiers, and specifically relates to an inorganic gelled activated carbon filter element and a preparation method thereof. Background technique [0002] In recent years, due to the rapid development of domestic industry and the acceleration of urbanization, a large amount of industrial sewage and domestic sewage have been produced. On the one hand, the quality of drinking water sources is deteriorating; on the other hand, users have put forward stricter requirements on the quality of drinking water. The quality of drinking water has become an issue of great concern to the water supply industry and residents. As a result, various household water purifiers have emerged. There are currently five water purification technologies popular in water purifiers: 1) activated carbon adsorption; 2) ultrafiltration machine, also known as hollow fiber filtration; 3) water purifie...
