Oyster shell pulverizing and screening device for production of soil remediation agent

Abstract

The invention discloses an oyster shell pulverizing and screening device for production of a soil remediation agent. The oyster shell pulverizing and screening device comprises a box body; two crushing rollers relatively rotating are rotationally mounted at the top end in the box body, flanges distributed at equal intervals are fixed to the circumferential outer walls of the crushing rollers, symmetrical supporting frames are fixed to the inner walls of the two opposite sides of the box body, and grinding mechanisms attached to the outer surfaces of the crushing rollers are fixed to the supporting frames; movable openings are formed in the outer walls of the two opposite sides of the box body, sliding rails are fixed to the bottom ends of the inner sides of the movable openings, sliding blocks are slidably clamped in the sliding rails, and the same screening mechanism is fixed to the tops of the sliding blocks; a guiding rod is fixed between the two sliding rails, and a guiding mechanism fixedly connected with the bottom of the screening mechanism is movably connected to the guiding rod in a sleeving mode; and the two sides of the guiding mechanism are connected with springs in a sleeved mode correspondingly, and the ends, away from the guiding mechanism, of the springs are fixedly connected with the sliding rails. Pulverizing work and screening work can be simultaneously conducted, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of oyster shell pulverization, in particular to an oyster shell pulverization screening device for the production of soil remediation agent. Background technique [0002] Soil heavy metal pollution refers to the phenomenon that due to the addition of metals to the soil due to human activities, the heavy metals in the soil are significantly higher than the original content, and the quality of the ecological environment is deteriorated. Soil heavy metal pollution poses a huge potential threat to the ecosystem due to its hidden, irreversible and long-term characteristics, and affects the health of humans and animals through the food chain; at the same time, heavy metal pollution can lead to degradation of soil fertility, reduction of agricultural product quality and The degradation of crop quality has seriously affected the environmental quality and sustainable economic development, and the severity of heavy me...
