The copper sulfate vacuum filter adopts a fixed vacuum box, the tape slides on the vacuum box, and the structure of the motion seal is formed between the vacuum box and the tape. The titanium material is corrosion-resistant. It can continuously and automatically complete filtration, cake washing, slag discharge, filter cloth regeneration and other process operations, and mother liquor and cake washing liquid can be collected in stages. It has high filtration efficiency, large production capacity, good washing efficiency, low moisture content and flexible operation.1. Ultrasonic generator: Our company adopts the ninth generation IGBT integrated circuit control, with automatic overheating protection, automatic frequency sweep, power frequency adjustable and so on. Main power components - modules used by German Simon Kang or Fuji Japan, the equipment has long service life, low failure rate, suitable for long-term, intermittent work requirements.
