Description

Technical Field

[0001] The utility model relates to the technical field of cooling kilns, in particular to a material crushing device for a rotary cooling kiln. Background Art

[0002] The rotary cooling kiln is composed of processes such as gas flow, fuel combustion, heat transfer and material movement. Its principle is to make the fuel burn fully and the heat of fuel combustion can be effectively transferred to the material. After the material receives the heat, a series of physical and chemical changes will occur, and finally the finished clinker will be formed. The material entering the rotary cooling kiln for cooling needs to be crushed to a certain state to increase the contact area and improve the cooling efficiency.

[0003] When optimizing the existing material crushing devices for rotary cooling kilns, most of them are reflected in how to increase the full contact between the material and the gas medium in the cavity, improve the production efficiency of the rotary kiln, and save energy. For example, the Chinese utility model patent with application number CN03145524.7 discloses "A multi-cylinder self-grinding and self-screening rotary kiln". In this device, a plurality of coaxial cylinders are arranged in the inner cavity of the kiln body and are nested, and each adjacent inner and outer cylinders have an inlet connected to each other, forming an inner cavity structure imitating an Archimedean spiral structure. The cylinder wall of each inner cylinder is made with a grid structure. This kind of rotary kiln can make the material fully contact with the gas phase medium under the continuous action of the screen and the coil plate on each inner cylinder in the kiln cavity, thereby improving the energy utilization and the production capacity of the rotary kiln. At the same time, the grinding roller in the central inner cylinder crushes and grinds the material into fine powder and then sends it out from the discharge port.

[0004] Although the above-mentioned material crushing device for rotary cooling kiln has certain advantages in improving the production efficiency of rotary kiln, it still has certain disadvantages: after the crushed material enters the cylinder, it is crushed by the grinding roller as the cylinder rotates, but the material is centrifugal and will move away from the grinding roller, and the material moves with the rotation force and is easy to pile up and move, resulting in a long time for the material to be completely crushed to meet the standards, and different degrees of crushing are likely to occur, and personnel will need to further screen it later.
