LIQUID CLEANING FILTER Russian patent published in 2000 - IPC

FIELD: filtration; mechanical engineering; mining-and-concentrating, chemical and other industries. SUBSTANCE: filter has two vacuum chambers which are embraced by endless filtering tape. Chambers are located directly in reservoir filled with liquid to be cleaned. Coarse filtrate is filtered to first (in way of motion of tape) chambers located inside other chamber; coarse filtrate is again fed to reservoir filled with starting liquid which is connected with this chamber by means of branch pipe. Filtration of liquid by second chamber is effected through filtering tape and sediment adhering to it after first chamber. Preliminary cleaning of starting liquid and filtration through sediment enhanced efficiency of filtration; fine filtrate formed in second chamber is removed through suction branch pipe. Regeneration unit is located above chambers. Filtering tape rising from liquid with sediment adhering to it is dried and sediment is removed. EFFECT: enhanced efficiency of cleaning. 1 dwg
