CONICAL THICKENER Russian patent published in 2005 - IPC

FIELD: sewage purification equipment.

SUBSTANCE: the invention is intended for purification of sewage in processing lines of sewage mechanical separation and impurities contained in them. The thickener contains a body, a filter component mounted inside it, which are made in the form of curvilinear surfaces dilating top-down, a conical splitter placed on the upper part of the filter component, branch-pipes of a source slurry feeding and withdrawal of the liquid and solid fractions, impermeable and made in the form of a spiral-screw partition mounted between the body and the filter component with formation of a curvilinear channel dilated downward with the length exceeding in two - three times the length of the generatrix of the side surface of the filter component. The sharp part of the splitter is located in the branch-pipe of source slurry feeding for its uniform distribution on the lateral surfaces of the filtering component by a thin layer. The technical result of the invention is an increased efficiency, cost-saving, compactness, reliability and ease of maintenance. The thickener may be used device can appear in roles of the self-maintained device for separation of suspended matters with loose structure.

EFFECT: the invention ensures increased efficiency, cost-saving, compactness, reliability and ease of maintenance.
