Description

Technical Field

[0001] This utility model belongs to the field of dust suppression technology for coke head unloading, and specifically relates to a dust suppression and filtration device for coke head. Background Technology

[0002] In coking production, the traditional discharge process involves materials falling directly onto the conveyor belt. During this descent, friction and collisions cause impacts, disturbing the surrounding air. This turbulent airflow carries small particles of coke dust, creating a harsh working environment. The resulting dust pollution not only causes severe air pollution but also seriously harms the health of workers. To reduce the impact and disturbance of materials during unloading and mitigate the adverse effects of dust dispersion, chute components are installed. These chute components guide the material along the inside of the chute, reducing impact and dust dispersion and effectively minimizing dust generation. However, even with this unloading method, dust still escapes externally at both the material inlet and outlet, causing dust to remain and continue to affect the working environment, pollute the atmosphere, and impact worker health.

[0003] In summary, there are some problems with dust emission at the inlet and outlet of the unloading chute during use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
