Problems solved by technology

However, the granular PE (PP) binder that binds granular activated carbon has the disadvantage of easily degrading the water purification performance and water passage function.
In addition, the commonly used activated carbon rods, activated carbon particles are easy to fall off the carbon rods and mix into drinking water to be discharged. Therefore, in order to solve this problem, manufacturers in the industry need to install UF ultrafiltration membrane or PP to remove fine dust at the back end of the activated carbon rods. cotton to remove dust

Abstract

The invention relates to an activated carbon rod, and in particular relates to an inorganic binder activated carbon rod and a manufacturing process thereof. The inorganic binder activated carbon rod is prepared from the following raw materials in percentage by weight: 70-90% of activated carbon and 10-30% of inorganic binder. The inorganic binder is one or more of kaolin, clay and loess. The inorganic binder activated carbon rod is capable of filtering various impurities such as residual chlorine and rust in tap water, is high in water purification performance and has the advantage of prolonging the service life and the change period of a filter element. The manufacturing process of the inorganic binder activated carbon rod comprises the following steps: carrying out wet stirring on the activated carbon and the inorganic binder, then compressing, ripening and drying; extruding into a cylindrical activated carbon rod by a pug mill; drying and cutting; molding under vacuum at 700-1000 DEG C to obtain the product. The manufacturing process is reasonable and the industrial production is easy.

Description

technical field [0001] The invention relates to an activated carbon rod, in particular to an inorganic binder activated carbon rod and a manufacturing process thereof. Background technique [0002] Under normal circumstances, the activated carbon carbon rod filter element installed on the water purifier is used to filter various impurities such as residual chlorine, rust and other organic substances contained in the tap water, and the shape is a hollow cylinder. [0003] Commonly used activated carbon rods are generally mixed granular activated carbon and granular PE (PP) binders, and cylindrical activated carbon rods are made by presses or extruders. However, the granular PE (PP) binder that binds the granular activated carbon has the disadvantage that the water purification performance and the water passing function are easily lowered. In addition, in the commonly used activated carbon rods, the activated carbon particles are easy to fall off the carbon rods and be mixed ...
