Description

Technical Field

[0001] The utility model relates to the technical field of coal cleaning equipment, in particular to multifunctional coal cleaning and utilization equipment. Background Art

[0002] Clean coal utilization equipment is a device specifically designed to clean coal after it's mined. Its primary function is to remove surface dust and impurities from the coal, thereby improving combustion efficiency and reducing environmental pollution. Freshly mined coal often has a large amount of dust adhering to its surface. This dust contains not only coal particles but also various minerals and impurities. Without effective cleaning, this dust can damage the environment during coal combustion or transportation, generating large amounts of waste gas and residue, and potentially posing a health risk.

[0003] Patent publication number CN216735933U discloses a coal cleaning and utilization device, including a main body and a spraying device, wherein the inner wall of the main body is provided with a conveyor belt, the surface of the conveyor belt is fixedly connected to a placement block, the end of the conveyor belt away from the placement block is fixedly connected to a base, the spraying device is provided on the surface of the placement block, the spraying device includes a connecting column and a connecting pipe, the connecting column is fixedly connected to the upper surface of the placement block, the connecting pipe is clamped with the inner wall of the connecting column, the surface of the connecting pipe is fixedly connected to a nozzle, the inner wall of the connecting column is slidably connected to a spring block, and the end of the spring block away from the connecting pipe is fixedly connected to a first spring. The utility model, by providing a spraying device, effectively sprays water on the coal mine, plays a role in reducing dust in the coal mine, reduces the situation where coal mine particles are scattered in the air, reduces the safety hazards of the equipment during use, and facilitates the normal use of the equipment.

[0004] The above-mentioned existing technology adopts a spray cleaning method during specific use, that is, by spraying water to flush the dust and impurities on the surface of the coal, thereby achieving coal cleaning. However, when the equipment is fed with coal, due to the impact and friction with the conveyor belt during the process of coal entering the equipment from the inlet, dust tends to be scattered from the inlet, and some dust will also enter the surrounding environment of the equipment. This will not only cause dust to escape during the cleaning process, but may also have an adverse effect on the health of the equipment operators. Long-term exposure to high-concentration dust environments may expose workers to health risks such as respiratory diseases. In view of this, we propose a multifunctional coal cleaning and utilization equipment. Utility Model Content
