Active carbon filter

Abstract

The invention discloses an active carbon filter which comprises a barrel and a bracket, wherein a water inlet is formed in the upper end of the barrel; an air inlet is formed in one side of the water inlet, and a water outlet is formed in the lower end; the barrel is fixed on the bracket; the interior of the barrel is provided with a first filter layer and a second filter layer which are same in structure from top to bottom, and both the first filter layer and the second filter layer comprise baffle plates and active carbon layers; both the first filter layer and the second filter layer are obliquely arranged in the barrel; the first filter layer and the second filter layer are provided with material inlets on higher positions and are provided with material outlets on lower positions; and a push plate is arranged above each material inlet. To change the active carbon, the gate of the material inlet is opened, the to-be-changed active carbon is pushed out of the material outlet by virtue of the push plate, new active carbon is added from the material inlet and the active carbon is uniformly spread by virtue of the push plate; and the active carbon filter is simple in structure, convenient and rapid to change the active carbon, time-saving and labor-saving, sufficient in filtration and high in production efficiency.

Description

technical field [0001] The invention relates to a device for filtering and purifying water, in particular to an activated carbon filter. Background technique [0002] Water purification treatment generally adopts mechanical filtration method or chemical and biological treatment method; usually mechanical filtration method is suitable for colloidal suspended solids or granular impurities; but for some harmful substances in water, that is, the water quality treatment of wastewater or sewage, usually Using chemical and biological treatment methods, it can treat harmful substances in wastewater or sewage to form a water purification effect. Activated carbon is an adsorbent that can absorb harmful substances in water. At the same time, because of its microporous filtration, it can also have a certain mechanical filtration to remove tiny colloidal suspended solids and granular impurities. It is used as a commonly used Water purification treatment materials; however, activated ...

AI Technical Summary

Problems solved by technology

Activated carbon is an adsorbent that can absorb harmful substances in water. At the same time, it can also have a certain mechanical filtration effect due to its microporous filtration effect, and remove tiny colloidal suspended solids and particulate impurities. It is used as a commonly used Water purification treatment materials; however, activated carbon is used for water purification. After a long time, the adsorption effect of activated carbon is greatly reduced because the adsorbed impurities are trapped inside the activated carbon, but the replacement of activated carbon is difficult, which affects production efficiency.
