包不銹鋼板框壓濾機

2023/07/18 分類:壓濾機百科 466

包不銹鋼板框壓濾機是一種常見的壓濾機類型，其主要由以下幾個部分組成：

框架：包不銹鋼板框壓濾機的框架一般采用不銹鋼材料制成，用于固定和支撐濾板和壓緊裝置。
濾板：濾板是包不銹鋼板框壓濾機的核心部件之一，通常由聚丙烯或聚乙烯材料制成。濾板上設有過濾孔和相應的密封槽，用于過濾和密封料液。
壓緊裝置：壓緊裝置用于將濾板壓緊，使料液在濾板之間形成過濾膜。壓緊裝置通常由液壓系統(tǒng)或機械系統(tǒng)控制，可自動或手動操作。
過濾系統(tǒng)：過濾系統(tǒng)包括濾板、密封件、管道、閥門等部件，用于將料液引入濾板之間進行過濾。
控制系統(tǒng)：控制系統(tǒng)用于控制包不銹鋼板框壓濾機的運行，包括自動控制和手動控制。其優(yōu)點包括耐腐蝕、耐高溫、易清洗、壽命長等
