The invention discloses an
activated carbon cleaning tank, which comprises a tank body, a filtrate tank, a
sprayer, a material frame and a pump, the lower side of the tank body is provided with a conical section with a liquid outlet channel which extends into the filtrate tank and is provided with a first
electromagnetic valve; the material frame is placed in the tank body; an annular partition net is arranged in the center of the material frame so as to divide the inner cavity into an inner cylinder cavity and an outer ring cavity; the spray head of the
sprayer extends into the inner cylindercavity; and the pump is respectively connected with the
sprayer and the filtrate tank through hoses. The sprayer is also connected with a washing liquid
bottle through a hose; by placing the materialframe filled with
activated carbon in the tank body and spraying a cleaning liquid with the sprayer, impurities in the
activated carbon are washed away, and waste liquid can be directly subjected toresource treatment or
hazardous waste treatment, the activated carbon cleaning tank is convenient and quick; an air cylinder drives a main liquid
pipe to move up and down, and a motor drives the mainliquid
pipe to rotate at a variable speed, so that an elastic liquid
pipe swings up and down telescopically, the outflow direction of a cleaning liquid is continuously changed, and spray dead angles are further reduced.
