Method for graded crushing of waste incineration slag block and low-energy-consumption equipment

Abstract

The invention provides a method for graded crushing of waste incineration slag block and low-energy-consumption equipment. The middle of the equipment is in a cylindrical shape, a standing shaft is mounted at the bottom of a cylinder, a plurality of rows of hammer shafts are mounted on the standing shaft, a hammer head is arranged on each hammer shaft, the hammer heads can be driven to rotate at the high speed by the standing shafts, and the equipment is mounted at the bottom of a waste incineration furnace; and the rotation radius of the hammer heads is gradually reduced from top to bottom, the weight of the hammer heads is gradually reduced from top to bottom, the hammer head at the top layer is in a rectangular shape, the hammer head at the bottom layer is in a right-angle ladder shape,the right angle edges are connected with the hammer shafts, the sharp angle of each right-angle ladder hammer head is gradually reduced from top to bottom, and a counter attack plate is mounted on the inner wall of the equipment. The slag blocks after the domestic waste incineration are crushed by using the equipment, the purpose of graded crushing is achieved, the equipment load is also reduced,the energy consumption due to the linear speed and high weight of a plurality of layers of hammer heads of existing equipment is reduced, the diameter of the slag block after crushing is 5-30 mm, andthe problem that transporting equipment is broken due to the falling of the large slag block is eliminated.

Description

technical field [0001] The invention belongs to the field of domestic garbage and other solid waste disposal, and in particular relates to a method for classifying and crushing garbage incineration slag blocks and low energy consumption equipment. Background technique [0002] With the continuous advancement of my country's urbanization process, the urban population continues to increase, and industrial production and residents' lives produce a large amount of domestic waste. In recent years, the frequent occurrence of domestic waste pollution has posed a great threat to people's life, health and property safety. The disposal of a large amount of domestic waste has become a difficult problem in environmental governance and an environmental protection problem that needs to be solved urgently. [0003] Incineration is a common form of municipal solid waste disposal. In the process of unloading domestic waste incinerators, hard and dense slag blocks with large volume (100mm~800...

AI Technical Summary

Problems solved by technology

[0003] Incineration is a common form of municipal solid waste disposal. In the process of unloading domestic waste incinerators, hard and dense slag blocks with large volume (100mm~800mm in diameter) often appear. Due to the large weight of slag blocks (some can exceed 50kg ) often smashes the conveying equipment when it falls, such as smashing the belt idler, breaking the zipper of the zipper machine, etc., which will cause large economic losses

In addition, the incinerated slag can generally be reused as building materials, and the hard, dense and large slag is not conducive to subsequent reuse.
