Description

Technical Field

[0001] The utility model belongs to the technical field of mine sand making machines, in particular to a crushing vortex cavity of a mine sand making machine. Background Art

[0002] In recent years, with the continuous development of engineering construction in my country and the country's strict management of river sand resources, there is an urgent need for a large amount of artificial sand to replace the use of natural sand and gravel, which has led to the rapid development of artificial sand equipment in the Chinese market.

[0003] The structural shape of the vortex crushing chamber is an annular space composed of two sections of cylinders, the upper and lower. The impeller rotates at high speed in the vortex crushing chamber. The material can also stay in the vortex crushing chamber to form a material lining. The material crushing process occurs in the vortex crushing chamber. The material lining separates the crushing action from the vortex crushing chamber wall, so that the crushing action is between the materials, playing the role of wear-resistant self-lining. The observation hole is used to observe the wear of the wear-resistant block at the launch port of the impeller flow channel and the wear of the top lining of the vortex crushing chamber. The observation hole is sealed and closed when the crusher is working. The distributor is fixed on the upper cylindrical section of the vortex crushing chamber. The high-speed rotation of the impeller generates airflow, which forms an internal self-circulation system in the vortex crushing chamber through the distributor and the impeller.

[0004] At present, the lining plates inside the existing vortex crushing chamber are mostly welded and fixed thereto, and the lining plates often collide with stones and are vulnerable parts. When the lining plates are damaged, it is difficult to replace them and the operation is relatively troublesome. In addition, since there is no blocking structure between the stones and the inner wall of the vortex crushing chamber, the stones often collide with the inner wall of the vortex crushing chamber, which easily causes wear of the chamber wall and affects the service life of the vortex crushing chamber.
