industrial self-cleaning wedge wire filtration system with stainless steel filter housing and motor driven scraper mechanism

Filtro autolimpante

Os filtros autolimpantes são utilizados em sistemas industriais de filtração de líquidos onde é necessária a remoção contínua de sólidos em suspensão sem necessidade de cartuchos ou sacos filtrantes descartáveis. Estes sistemas de filtração utilizam elementos filtrantes de fio em cunha combinados com mecanismos de limpeza por raspador para manter o funcionamento estável durante a filtração.

Os sistemas industriais de autofiltração são normalmente utilizados no tratamento de água, revestimentos, produtos químicos, óleos e líquidos de processo, onde a remoção fiável de partículas e o tempo mínimo de inatividade para manutenção são essenciais.

Self-cleaning filtration – technical overview

Self-cleaning filters are industrial filtration systems designed for continuous removal of suspended solids from liquids without the need for disposable filter elements. These systems typically use stainless steel wedge wire filter elements combined with mechanical scraper cleaning mechanisms to maintain filtration performance during operation.

In industrial filtration systems the filter element captures suspended particles on the external surface of the screen while a rotating scraper removes accumulated solids. The particles are transported to a sediment chamber and discharged through a drain valve without interrupting the filtration process.

Operating principle

Self-cleaning wedge wire filters operate using a cylindrical filter element with precision slots that retain particles while allowing the process liquid to pass through. During operation the filter element rotates while a scraper blade removes solids from the screen surface. These particles settle in the lower chamber of the filter housing and are periodically discharged using system pressure.
