[0002] Filtration devices are widely used in chemical industry, petroleum, coal, environmental protection, food and other fields to achieve solid-liquid separation. At present, box-type filter presses and belt-type filters are mainly used, and box-type filter presses have equipment investment. Large, complex structure and only intermittent operation lead to defects such as low work efficiency, large energy consumption and poor filtering effect
The currently used belt filter, especially the belt filter with a high-pressure filtration system, can improve the extrusion effect on the separated material, reduce the moisture content of the solid material, and realize continuous operation, but it still has a large volume. , high energy consumption and complex structure defects

The invention discloses a belt-type negative pressure filter device, which comprises a filter transmission mechanism and a filter chamber, wherein the filter transmission mechanism includes a rotating wheel and a filter belt, and the filter belt is wound around the outer peripheries of the two rotating wheels to form a filter transmission mechanism; the filter chamber is one end The open shell is set between the two surfaces formed by the filter belt. The opening end of the filter chamber is a rectangle matching the width of the filter belt, and the edge of the opening end of the filter chamber touches the filter belt; in addition, the filter chamber The outer wall is provided with an air outlet pipe, and the opening of the first end of the air outlet pipe is provided with a cone baffle. The two ends are opened outside the filter chamber and are connected with a vacuum pump to form a negative pressure state in the filter chamber.
