Description

Technical Field

[0002] Environmental governance refers to the protection, restoration and improvement of the environment through a series of policies, regulations, technical means and management measures to reduce or eliminate environmental pollution, protect the ecosystem and promote sustainable development. With the acceleration of global industrialization and urbanization, the impact of human activities on the environment is increasing, and environmental pollution problems are becoming more serious. Effective environmental governance is of great significance to protecting the earth's ecosystem, ensuring human health and achieving sustainable development.

[0003] Solid waste treatment equipment is an important part of environmental governance. It can be used to treat various types of solid waste, mainly including solid waste crushing, classification, compaction, incineration, landfill and other treatment processes. The types and sizes of solid waste treatment equipment vary, and can be selected according to the nature of the solid waste and treatment requirements.

[0004] Incineration equipment is a commonly used solid waste treatment equipment, which converts solid waste into ash and waste gas through high-temperature combustion. Incineration is one of the important methods of solid waste treatment, which can effectively reduce the volume and weight of waste. At the same time, by controlling the combustion process, it can also reduce the pollution of waste to the environment.

[0005] However, the existing technology is unable to distinguish ferromagnetic materials when burning solid waste. Ferromagnetic materials may not be completely burned during the incineration process, resulting in the possibility of unburned ferromagnetic materials in the exhaust gas, which increases the difficulty and cost of exhaust gas treatment.

[0042] Specifically, the crushing assembly 4 includes a crushing roller 41 symmetrically rotatably arranged in the middle of the frame 1, and the crushing roller 41 is located on the outside of the frame 1 and is fixedly provided with a gear 42, and the two gears 42 are meshed and connected. A first motor 43 is fixedly provided on the side of the frame 1 away from the gear 42, and the output end of the first motor 43 is fixedly connected to a gear 42.

[0043] In a further embodiment, the crushing roller 41 crushes the solid waste through rotational motion, turning large pieces of solid waste into small pieces, thereby improving the efficiency of subsequent processing. The solid waste enters the equipment through the feed port 2 and falls between the crushing rollers 41 of the crushing assembly 4. The first motor 43 is started to drive the gear 42 to rotate.
