AI Technical Summary

Technical Problem

The lack of an effective material turning mechanism in existing pyrolysis units leads to the accumulation of materials in flotation tailings during pyrolysis, resulting in uneven reaction and affecting the quality and yield of magnesium hydroxide products.

Method used

A pyrolysis device for producing magnesium hydroxide from flotation tailings is used. The incomplete meshing of the tooth and tooth plate drives the connecting plate to vibrate up and down, which in turn drives the connecting rod and the dumping block to turn the material over, ensuring that the material is fully mixed with the reaction medium.

Benefits of technology

This process ensures thorough mixing of materials and the reaction medium, improving the efficiency of the pyrolysis reaction and the uniformity and purity of the magnesium hydroxide product.

Abstract

The utility model belongs to the field of waste resource utilization technology especially is a kind of pyrolysis device of magnesium hydroxide preparation of flotation tailings, including bottom plate.The utility model through the crushing addition device of flotation tailings by feed inlet, heating plate starts work to heat pyrolysis box ontology inside, temperature sensor real -time monitoring temperature in pyrolysis box ontology, and temperature signal is transmitted to controller, and the power of automatic regulation heating plate, start first motor drive incomplete tooth rotation, due to the meshing relationship of incomplete tooth and tooth plate, when incomplete tooth and tooth plate mesh, it will drive tooth plate to move upwards, and then drive connecting plate to slide upwards along T-shaped rod, at this moment, spring is compressed, when incomplete tooth rotates to the position of not meshing with tooth plate, under the action of spring elasticity, connecting plate will slide down reset, the up-and-down vibration of connecting plate will drive connecting rod and inverted block to move up and down, to turn over the material in pyrolysis box ontology, make material and reaction medium fully mix.
