Zdu series continuous belt vacuum filter is a device for solid-liquid separation driven by vacuum negative pressure. Structurally, the filter section is arranged along the horizontal length direction, which can continuously complete filtration, washing, drying and filter cloth regeneration. The device has high filtration efficiency, large production capacity, good washing effect, low moisture content of filter cake and flexible operation, Low maintenance cost. It can be widely used in solid-liquid separation in metallurgy, mining, chemical industry, papermaking, food, pharmacy, environmental protection and other fields, especially in gypsum dehydration in flue gas desulfurization (FGD).
The equipment adopts a fixed vacuum box, the tape slides on the vacuum box, and a moving sealing structure is formed between the vacuum box and the tape. It can continuously and automatically complete the process operations such as filtration, filter cake washing, slag unloading and filter cloth regeneration, and the mother liquor and filter cake washing liquid can be collected in sections. It has the advantages of high filtration efficiency, large production capacity, good washing efficiency, low moisture content of filter cake, flexible operation and simple maintenance. After years of improvement and improvement by our company, the technical performance and quality of the machine have reached the international advanced level. It has been widely used in metallurgy, mining, chemical industry, wet flue gas desulfurization of power plant, coal chemical industry, papermaking, food, pharmacy and environmental protection.
Annular rubber drainage belt has high tensile strength and long service life.
An annular friction belt is arranged between the vacuum box and the adhesive tape, which is sealed and lubricated with water, which can maintain a high vacuum and reduce the friction of the rubber belt. The belt adopts mandrel sealing idler or water film support to reduce the running resistance and prolong the service life of the belt.
Vacuum drainage adopts various methods such as free drop type (high-level drainage), automatic drainage type (zero position drainage) and so on to meet the requirements of various working conditions. The overall structure adopts modular design, which can be assembled flexibly and is convenient for transportation and installation.
DCS technology is applied in the control system, which can realize on-site and remote automatic control.
