The invention discloses a scraper device for filter cake discharge from a filter plate of a pressure filter. The device is provided with a fixed bracket part, a moving carriage part, a lifting frame part, a cylinder body assembly part and a scraper part; cross beams and bracket vertical beams form a frame; the fixed bracket is provided with support legs which are mounted on the thrust plate and an oil cylinder seat of the pressure filter; the spindle of a moving carriage base is provided with moving pulleys; the upper end of a moving carriage is provided with a lifting speed reducing motor mounting chainwheel; a cylinder connecting block is connected with a movable clamp plate; and the movable clamp plate is provided with a tool seat and a scraper. The scraper device disclosed by the invention has the beneficial effects that the filter cake stuck on the filter plate of the pressure filter is completely scraped, the filter cake recovery rate is improved, the filter plate has good sealing performance and operates quickly, the material filtering circulation period is short, the service life of a filter cloth is prolonged, the cost is lowered, the filtering efficiency is improved, the operation is simple, and the use is safe.
Description
technical field [0001] The invention relates to a cake unloading scraper device for a filter plate of a filter press. Background technique [0002] The filter press is the filtration equipment in the solid-liquid separation machinery industry. The box filter plate is the main filter element of the filter press. When the filter press is filtering, the feed pump injects the material into the filter chamber of the filter plate, and installs it through the filter plate. The particles in the filter cloth or other filter media retained in the material remain in the filter chamber, and the filtrate is discharged from the outlet hole to form a filter cake in the filter chamber, and then the filter plate is pulled apart by the plate puller of the filter press to automatically drop the filter cake to be unloaded. Remove the filter cake to achieve the purpose of filtration. [0003] Due to the development and expansion of the solid-liquid separation industry and the wide application o...
