Abstract

The invention belongs to the technical field of ardealite recycling, and particularly relates to sludge curing agent preparation equipment and method based on ardealite solid waste, the equipment comprises a vibrating screen, the vibrating screen comprises a main body, a vibrating motor, a flow guide plate, a sieve, a sieve vibrating marble and a sieve cleaning mechanism; by arranging the screen cleaning mechanism, when ardealite particles penetrate through the upper screen, part of the ardealite particles are clamped into meshes of the upper screen, a worker controls the screen cleaning mechanism to move between the upper screen and the lower screen through the controller, and the screen cleaning mechanism pushes the ardealite particles clamped into the meshes of the upper screen upwards from the bottom surface of the upper screen; the ardealite particles clamped in the meshes of the upper screen are discharged out of the upper screen, the meshes in the upper screen are dredged, the effective aperture ratio of the upper screen in the ardealite particle screening process is increased, the effective screening area of the upper screen in the screening process is increased, and therefore the screening effect of the vibrating screen in preparation of an ardealite particle curing agent is improved.

Description

technical field [0001] The invention belongs to the technical field of phosphogypsum reuse, in particular to equipment and method for preparing sludge solidifying agent based on phosphogypsum solid waste. Background technique [0002] Phosphogypsum is a solid waste produced in the wet process phosphoric acid process. However, after the obtained phosphogypsum is naturally stacked, as its particles gather and absorb organic matter in the air, more particles accumulate together to form a larger particle size. Large polyhedrons with irregular shapes, such as plates, cones, etc. Phosphogypsum contains mineral structures, such as calcium sulfate, alumina and iron oxide, etc. These insoluble components have good electrolyte properties and high structural strength. In terms of sludge dehydration, they are good for preparing sludge curing agents. Material. [0003] Before the use of phosphogypsum in the preparation of sludge curing agent, the surface of untreated phosphogypsum is n...
