Coal hydrotalcite composite material preparation equipment

The invention discloses coal hydrotalcite composite material preparation equipment which is structurally provided with a hearth, a cover door, a control cabinet and a control panel, a heated block is heated and expanded to drive a magnetic rod to displace, so that the magnetic rod generates two-end pulling force on a pull spring, and the pull spring is reversely pulled back to reset the magnetic rod to drive the heated block to contract and fold; and then the connecting rod is driven to reversely pull a displacement body back, so that the displacement body moves in a reciprocating manner, a turbulent flow effect is generated on the airflow in the cavity groove, and wrapped coal crystal molecules are further finely crushed conveniently, and different acting forces are generated on the upper end and the lower end of an arc rod under the action of a top collision ball. A spring wound at the outer end of the arc rod further assists the arc rod to penetrate through a clamping movable groove to perform position cha
