Paste tank
Cylindrical steel tank to contain the paste. The tank inside part is turned
and thermally stretched. The tank is closed in the upper part with a stainless steel AISI 304 lid, where there are the inspection doors, the tube for cooling air inlet and outlet, the tubes for the inlet of acid and water, the lead inlet coming from the dosing silo.
The paste mixed and readies to be paste is extracted using the door in the front part of the tank.
MIXING SYSTEM
The rotating paddles produce a complete mixing action of the various components (lead, acid, water and additives) to obtain a uniform and easily pasting paste. The mixer is equipped with scraping paddles, which clean perfectly the inside of the mixer.
Cooling system
In the mixing cycle is essential the temperature produced by the exothermic reaction developed between the H2SO4 and the lead oxide. The temperature is maintained to the values fixed using the two cooling systems assuring a good quality of paste reparation. The first cooling system by means of a fan blows the paste surface cooling it , the second one by means of circulating water maintains the bottom of tank cool. The air comes directly inside the vacuum fan system connected with the air depuration system. (scrubber). The machine vacuum-operated avoids dust and steams exit in case of inspection doors opening.
