The present invention provides a plate-frame type algae collection device, which comprises a culture unit for receiving algae liquid. The culture unit is connected with a press-filtering unit. The press-filtering unit is connected with a water supply unit. Thus, a user may first culture the algae using the culture unit, and then employs the press-filtering unit to rapidly separate the algae contained in the algae fluid by press-filtering manner, and further employs the water supply unit to supply fresh water for washing the algae, so as to remove the culture liquid possibly contained in the algae. This invention not only can provide higher algae collection efficiency, but also greatly reduce the algae collection time to achieve the effect of both energy and time saving.一種板框式藻類收集裝置,其係具有一培養單元,可供容置一藻液,且該培養單元係連接有一壓濾單元,該壓濾單元係連接有一供水單元,藉此,讓使用者可先利用該培養單元培養藻類,再透過該壓濾單元利用壓濾之方式快速的分離出該藻液所含有之藻類,並進一步透過該供水單元輸入清水清洗該藻類,以去除該藻類可能含有之培養液,從而使本發明不僅會具有較高之藻類收集效率,而可大幅縮短藻類之收集時間,而可達到節能省時之效果。100‧‧‧板框式藻類收集裝置10‧‧‧培養單元11‧‧‧培養槽111‧‧‧供液口12‧‧‧第一泵浦20‧‧‧壓濾單元21‧‧‧基座211‧‧‧輸入口212‧‧‧輸出口22‧‧‧板框23‧‧‧壓濾室231‧‧‧濾室入口232‧‧‧濾室出口24‧‧‧濾材25‧‧‧輸入通道26‧‧‧輸出通道27‧‧‧壓板28‧‧‧壓缸30‧‧‧供水單元31‧‧‧儲水槽311‧‧‧供水口32‧‧‧第二泵浦40‧‧‧供氣單元41‧‧‧空壓機411‧‧‧供氣口50‧‧‧連接單元51‧‧‧第一控制閥52‧‧‧供液管53‧‧‧供水管54‧‧‧供氣管55‧‧‧輸入管56‧‧‧輸出管60‧‧‧乾燥單元61‧‧‧輸送帶62‧‧‧熱風機200‧‧‧外界之排水系統
