Waste slurry diaphragm filter pressing equipment for pigment production

Abstract

The invention relates to the technical field of diaphragm filter pressing. The invention further discloses waste slurry diaphragm filter pressing equipment for pigment production. The waste slurry diaphragm filter pressing equipment includes a base; the upper end of the base is fixedly connected with a mounting plate; a filter pressing box with an opening in one side is fixedly connected to the vertical side wall of the mounting plate; a plurality of filtering holes are uniformly formed in the bottom of a filter pressing box in a rectangular shape at equal intervals; a hydraulic cylinder is mounted outside the filter pressing box, and the output end of the hydraulic cylinder penetrates through the wall of the filter pressing box, extends into the filter pressing box and is fixedly connected with a push plate; the other side of the push plate is fixedly connected with a diaphragm filter plate, a sealing block is slidably connected into the end, away from the push plate, of the filter pressing box, and the other side of the sealing block is fixedly connected with a cover plate. According to the waste slurry membrane filter pressing equipment for pigment production, the filter pressing degree of waste slurry can be accurately adjusted according to the input amount of the waste slurry, so that a proper filter cake thickness is pressed out, moisture in the waste slurry can be fullypressed out, and later filter cake crushing and drying treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of membrane filter press, in particular to a membrane filter press equipment for waste slurry used in pigment production. Background technique [0002] Pigment is a substance that can make an object dyed with color. Pigments are soluble and insoluble, and there are inorganic and organic differences. Inorganic pigments are generally mineral substances. Humans have known for a long time to use inorganic pigments, using colored soil and ores, to paint on rock walls and smear their bodies. Organic pigments are generally obtained from plants and marine animals, such as madder indigo, garcinia cambogia, and ancient Roman purple extracted from shellfish. The diaphragm filter press separates the mud and liquid, so that the liquid and the slurry are separated, so that the slurry can be recycled, saving a lot of pigment resources, and avoiding the waste slurry being directly discharged into the river to cause pollut...
