Description

Technical Field

[0002] Solid waste refers to solid and semi-solid waste materials generated by human beings in production, consumption, life and other activities, commonly known as "garbage". Solid waste is divided into domestic waste, industrial solid waste and agricultural solid waste. From the analysis of the relationship between solid waste and the environment, resources and society, solid waste is polluting, resource-based and social. Solid waste mainly includes solid particles, garbage, slag, sludge, discarded products, broken utensils, defective products, animal carcasses, spoiled food, human and animal feces, etc. When testing and processing solid waste, it is often necessary to crush and grind the solid waste.

[0076] The crushed solid waste falls into the drainage tube 4 and enters the gap between the upper grinding disc 8 and the lower grinding disc 7.

Under the meshing transmission of the second circular gear 803 and the second gear ring 801, the upper grinding disc 8 rotates. The upper grinding disc 8 rotates in opposite directions to the lower grinding disc 7, so that the grinding teeth on both grind the solid waste. The ground solid waste gradually falls to the bottom of the grinding chamber and is finally discharged through the second material taking port 203.

[0077] During the crushing and grinding process, solid waste can be sampled, and the sampled samples have different particle sizes, which provides convenience for subsequent solid waste detection tests.
