Embodiment

[0036] Such as Figures 1 to 7 shown. The present invention is a high-dryness dehydration device for a filter press, comprising a filter frame base 1, two surfaces of the filter frame base 1 are respectively symmetrically provided with two concave cavities 2 with the same structure, and each concave cavity 2 A hydraulic membrane 4, a filter plate 5, a jacket 8 and a filter cloth 7 are arranged sequentially from the inside to the outside;

[0037] The bottom of the cavity 2 is provided with hydraulic grooves 3, and each hydraulic groove 3 communicates with each other through the hydraulic oil injection port 11 opened in the middle of the filter frame base 1, and the hydraulic oil injection port 11 is opened inside the filter frame base 1. The channels connected to the external hydraulic oil injection equipment;

[0038] A feed inlet 9 is provided on the frame of the filter frame base 1, and the feed inlet 9 communicates with the cavity 2 (the outer position of the filter clot...

Abstract

The invention discloses a high-dryness dewatering device for a filter press and a dewatering method thereof. The high-dryness dewatering device comprises a filter frame matrix, wherein two cavities with the same structure are respectively and symmetrically formed in the two faces of the filter frame matrix, and a hydraulic film, a filter plate, a jacket and a filter cloth are sequentially arranged in each cavity from inside to outside; a hydraulic groove is formed in the bottom of each cavity, and the hydraulic grooves are communicated with each other through a hydraulic oil injection port in the middle of the filter frame matrix; a feed inlet is formed in a border of the filter frame matrix and is communicated with the cavity through a side groove. The filter plate is movably arranged between the hydraulic film and the jacket, and can move towards the filter cloth when being applied by an external thrust. The device has the advantages that the structure is simple, the operation is convenient, and a solid-liquid mixed material between the filter plates is driven by a high-pressure hydraulic oil, so that the extrusion pressure is greatly improved, liquid in the solid-liquid mixed material can be fully extruded out, and the solid content is greatly improved.

Description

technical field [0001] The invention relates to the field of filter press technology, in particular to a high-dryness dehydration device for a filter press and a dehydration method thereof. Background technique [0002] Filter press is a commonly used solid-liquid separation equipment, widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries. The basic principle of solid-liquid separation is: the mixed liquid flows through the filter medium (filter cloth), the solid stays on the filter cloth, and gradually accumulates on the filter cloth to form a filter mud cake, while the filtrate part penetrates the filter cloth and becomes solid-free of serum. [0003] The filter plate of the existing general filter press uses a combination of a diaphragm filter plate and a box-type filter plate, wherein the box-type filter plate is a solid structure, and the diaphragm filter plate is composed of a diaphragm and a cor...
