Problems solved by technology

[0002] Rotary kiln is a kind of calcination equipment widely used in building materials, metallurgy, chemical industry, environmental protection and other industries. However, due to the high specific gravity of these materials, simple means such as rotation and inclination of the heating furnace cylinder of the rotary kiln cannot completely separate the materials from the inner wall of the furnace cylinder and move evenly from the feeding end to the discharging end. It often leads to the problem that the low temperature part of the raw material is not burnt through and the content is insufficient, while the high temperature part of the product has burned to death and loses its activity.

Abstract

The invention relates to a percussive device of a rotary kiln. The percussive device of the rotary kiln comprises a hollow cavity and a ball body, the ball body is flexibly arranged inside the hollow cavity, one end of the hollow cavity is fixed in the external wall of a heating furnace barrel of the rotary kiln, the ball body and the external wall of the heating furnace barrel of the rotary kiln are in a spaced percussive state, the hollow cavity is polyhedron-shaped, or cylinder-shaped or cage-shaped, and the hollow cavity is vertically fixed on the external wall of the heating furnace barrel of the rotary kiln. The percussive device of the rotary kiln enables materials to leave the internal wall of the heating furnace barrel quickly, and ensures that material heating inside the heating furnace barrel is completely controllable, and therefore bonding and scorch of the materials in the inner wall of the heating furnace barrel are avoided, and quality and yield coefficient of calcined products are guaranteed, and meanwhile service life of the rotary kiln is prolonged, and production cost of the products is reduced.

Description

technical field [0001] The invention relates to an impact device, in particular to an impact device for a rotary kiln. Background technique [0002] Rotary kiln is a kind of calcination equipment widely used in building materials, metallurgy, chemical industry, environmental protection and other industries. However, due to the high specific gravity of these materials, simple means such as rotation and inclination of the heating furnace cylinder of the rotary kiln cannot completely separate the materials from the inner wall of the furnace cylinder and move evenly from the feeding end to the discharging end. It often causes the problem that the low temperature part of the raw material is not burned through and the content is insufficient, while the high temperature part of the product has burned to death and loses its activity. Contents of the invention [0003] The invention overcomes the disadvantages of the traditional rotary kiln and provides an impingement device for t...
