Description

Technical Field

[0001] The utility model belongs to the technical field of building crushing devices, and particularly relates to a building crushing device for preventing dust. Background Technique

[0002] During the processes of building demolition, reconstruction, etc., a large amount of construction waste, such as wooden boards, is generated. After crushing these construction wastes, they can be reused as recycled aggregates. These recycled aggregates can be used to prepare building materials such as recycled boards, which not only reduces the landfill amount of construction waste, reduces the pressure on the environment, but also realizes the recycling of resources and saves natural resources:

[0003] When crushing building materials such as wooden boards, a large amount of dust is generated. These dusts will not only affect air quality and reduce visibility, but may also have a negative impact on ecological environments such as soil and water bodies. Moreover, a large amount of dust will pose a serious threat to the physical health of workers. Long-term inhalation of dust may cause workers to suffer from occupational diseases such as pneumoconiosis:

[0004] When existing equipment is in use, due to the increased gaps between particles of crushed building materials such as wooden boards, subsequent transportation and storage operations need to be carried out multiple times, which is rather troublesome and will generate a large amount of dust. Therefore, we propose a building crushing device for preventing dust. Content of the Utility Model

The water pump can transport the water in the water storage tank into the rotating nozzle through the water pipe. Due to its special structure, the rotating nozzle will rotate by itself during the process of spraying water. The rotating nozzle continuously sprays water into the main body of the crusher, which can moisten the building materials such as wooden boards, preventing the raising of dust. By spraying fine water mist into the crushing area, the water mist can fully contact with the dust particles of the crushed building materials, causing the dust to settle to the ground, effectively suppressing the generation and flying of dust, reducing the dust content in the air, and can also timely remove the dust particles attached to the inside of the device and the crushed materials, etc., improving the crushing amount of the device for building materials.
