Embodiment Construction

[0013] The structure and operating principle of the belt pressurized filter device provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] like figure 1 Shown is a structural schematic diagram of a belt pressurized filter device provided by the present invention. That is, the structure of the belt-type pressurized filter device includes a sealed pressurized chamber 2 for entering the high-pressure gas inlet 1, and an open filter chamber 3 for storing filtrate is arranged in the middle of the sealed pressurized chamber. The two ends of the filter chamber are respectively provided with a roller 4 and a power wheel 5. The filter belt 6 for solid-liquid separation is wound on the roller and the power wheel to form a conveyor belt for solid materials 11. The filter belt 6 will seal the pressurized chamber. 2 and filter chamber 3 are divided into two independent spaces. A solid material container 8 is prov...

Abstract

The present invention belongs to the field of filtering equipment technology, and is especially one kind of belt type pressure filter. Technologically, the belt type pressure filter is provided with one sealed pressurizing compartment with air inlet, material inlet and filtering chamber; one driving wheel and one sliding mechanism fixed separately to ends of the filtering chamber; one filter belt around the filter driving mechanism comprising the driving wheel and the sliding mechanism; one material container and one filtrate outlet set in the ends of the filter driving mechanism. The belt type pressure filter has the features of relatively high air pressure difference between the pressurizing compartment and the filtering chamber, complete separation of solid and liquid, excellent filtering effect wide application range, simple structure and convenient maintenance.

Description

technical field [0001] The invention belongs to the technical field of filtering equipment, in particular to a belt-type pressurized filtering device. Background technique [0002] Filtration device is an important equipment widely used in chemical industry, petroleum, mineral processing, coal, environmental protection, pharmaceutical and food industries to achieve solid phase and liquid phase separation. At present, box filter press and belt filter are mainly used. Among them, the box-type filter press has defects such as large equipment investment, large volume and complex structure, and can only be operated intermittently due to structural reasons, resulting in low work efficiency, large energy consumption, and poor filtering effect. The utility model patents with patent Nos. 00250342.5 and 00266002.4 respectively disclose the name of a belt filter press, and its structure includes a feeding mechanism, an upper net, a lower net, a transmission ro...
