Description

Technical Field

[0001] The utility model relates to the technical field of refractory brick production, in particular to a dust collection device for crushing recycled refractory bricks. Background Technique

[0002] During the production, processing and transportation of refractory bricks, there will always be some damages. Moreover, a part of the produced refractory bricks are scrapped due to problems such as their appearance geometric dimensions, cracks, and twists. There are also some test blocks for experiments. These refractory bricks cannot be reused due to their different brick shapes. A lot of dust and debris will be generated during the crushing process, polluting the environment and endangering the health of workers. When the dust is discharged into the air, it will pollute the air quality and pose a hidden danger to our environment.

[0003] After retrieval, the patent with publication number CN205700684U discloses a dust-free recycling and crushing device for refractory bricks, including a support platform.
