Abstract

The invention discloses a comprehensive utilization device for municipal sludge incineration ash, comprising a rectangular shell, a mixing barrel, a conical grinding sleeve, a conical grinding head, a lifting mechanism, a water injection mechanism, an extrusion mechanism and a feeding mechanism. The lifting mechanism accurately controls the conical grinding head through a spline shaft and a spline sleeve to achieve efficient rolling and crushing of the ash, and significantly improves the fineness and uniformity of the ash. The water injection mechanism achieves uniform water addition to the bottom of the mixing barrel through a U-shaped tube and a sprinkler head, and cooperates with the stirring action of a stirring rod to ensure full mixing of the ash with water and other additives, thereby improving the effect of comprehensive utilization of sludge incineration ash. The extrusion mechanism achieves automatic extrusion molding of the sludge incineration ash through the coordinated work of a crank, a connecting rod and a gear, thereby improving production efficiency and yield rate. The invention not only improves the resource utilization rate of sludge incineration ash, but also reduces production costs and reduces environmental pollution, and is of great significance for promoting green buildings and sustainable development.
