Material mixing machine
Technical Field
The invention relates to the technical field of solid waste treatment, in particular to a mixer.
Background
Hazardous waste is extremely damaging to the environment and poses a great threat to human and livestock health, so special treatment is required. The incineration treatment is a method for treating the dangerous waste by taking pyrolysis and deep oxidation as main means and changing the physical, chemical or biological characteristics and components of the solid waste, and simultaneously achieves the purposes of harmlessness, reduction and recycling.
Incineration disposal can be divided into two approaches: one is to build special incineration equipment, namely investment and construction of incineration power plants; and the other method is to carry out incineration treatment after the improvement on the basis of the prior art, namely the cement kiln is used for treating hazardous waste in a synergic manner.
The hazardous waste treatment process flow generally adopts mechanical equipment to mix and crush materials, and then the materials enter a feeding point (a decomposing furnace or a kiln tail smoke chamber) of an incinerator or a cement kiln through lifting equipment and feeding facilities. The solid waste is crushed, mixed with semi-solid and non-solid waste to prepare slurry mixture, and then fed into the material inlet of incinerator and cement kiln.
In order to reduce the shape of the waste entering the incinerator system, the solid waste must be crushed in advance, and the crusher generally adopts a double-rotating shaft rotary shearing crushing mode which is the currently preferred solution for crushing complex materials and is driven by hydraulic pressure. Solid waste such as oiled cotton yarn, packaging bags and the like can generate long-strip-shaped, blocky and fibrous materials after being crushed. The waste after the crushing treatment can be subjected to subsequent treatment after being mixed with various semi-fluid solid wastes and the crushed materials of the packaging bags in different incineration treatment process flows, and the mixing requirement is uniform and stable. The existing traditional blendors are of a paddle type, a pear type and a spiral ribbon type, in the using process, due to the fact that a large number of long strips and fibrous materials exist in the materials, the strips which are easy to wind are often formed, fibrous solids are wound on the blades, the stirring shaft and the like, the mixing effect is reduced due to the winding of the large number of solid materials, the mixing space is seriously blocked, the blender is shut down and manually cleaned, the continuous operation of the process flow of a treatment system is seriously influenced, and great harm is also caused to the physical health of operators in the cleaning process.
