Flocculating, concentrating and filter-pressing integrated belt-type press filter

The utility model discloses a flocculating, concentrating and filter pressing integrated belt pressure filter, which belongs to the solid-liquid separation technology field in order to solve the problems in prior belt pressure filter that that structure is complex, the dewatering efficiency is low. A flocculating region, a concentrating and dewatering region, a gravity dewatering region, a transition dewatering region and a pressure dewatering region are sequentially arranged on a pressure filter main frame from the slurry entering end; the concentrating and dewatering region is connected on the flocculating region of the machine frame; the gravity dewatering region is connected at the rear part of the concentrating and dewatering region; the pressure dewatering region is connected at the rear part of the gravity dewatering region; a pressure filtering belt which is integrated with an upper filtering belt, a lower filtering belt and a gravity dewatering filtering belt into one body is arranged on a pressure roller group of the pressure dewatering region; and a filtering belt tensioner and a pressure deviation rectifier which is connected with the pressure roller group are respectively arranged on the pressure filter main frame, and a mud-receiving hopper which is connected with an end roller of the pressure roller group is arranged at the side of the pressure filter main frame. The pressure filter has the advantages that: the structure is novel, the filter is applied to the mud dewatering in the wastewater and sewage treatment, as well as to the solid-liquid separation in the fields of petroleum, chemical engineering, metallurgy, paper making, mining industry, food industry and the like.
