TECHNICAL FIELD

[0001] The utility model belongs to the technical field of rotary kiln, specifically relates to a rotary kiln stirring device. BACKGROUND

[0002] At present, manganese metallurgy is the process of processing manganese ore into manganese powder and then applying in industry. The main application field of manganese metallurgy is metallurgical industry and chemical industry, and it also has a certain position in other fields.

[0003] In the metallurgical industry, the calcination rotary kiln is the key equipment for the pretreatment of solid materials, and can also process tailings and other materials. It can perform calcination processing on materials, dry and dehydrate materials, and optimize and improve product quality.

[0004] In the utility model patent with the patent authorization announcement number CN219656567U, a rotary kiln is disclosed, which comprises a rotary kiln body, a plurality of wheel belts arranged on the rotary kiln body, a first trigger arranged on the wheel belt, and a second trigger arranged on the rotary kiln body; one side of the rotary kiln body is provided with a first proximity switch matched with the first trigger and a second proximity switch matched with the second trigger.

[0005] However, when the rotary kiln calcines certain materials, the materials may be bonded on the kiln wall to form a ring. The ring reduces the effective inner diameter of the kiln body, affecting the normal movement of the materials and heat exchange. Moreover, as the ring thickens, it may cause poor ventilation in the kiln, further affecting the combustion and calcination effect; and the process of removing the ring is relatively complex; usually, manual cleaning with special tools or some physical and chemical methods are required. This not only increases the labor intensity, but also may cause damage to the kiln body. In addition, the material mixing uniformity is limited. Although the rotary kiln can make the materials tumble and mix to some extent during rotation, the mixing effect may not be ideal for materials with large particle size difference or large density difference. SUMMARY

This not only increases the labor intensity, but also may cause damage to the kiln body. In addition, the material mixing uniformity is limited, although the rotary kiln can make the materials tumble and mix to some extent during rotation, but for some materials with large particle size difference or large density difference, the mixing effect may not be ideal.

[0008] The principle of the present invention is that by pushing the counterweight block to contact with the fixed disc, the plug rod is inserted into the fixed disc and drives the end head to contact with the fixed disc. In this process, when the end head contacts the plug plate, under the extrusion of force, the plug plate can be pushed to move in the direction away from the plug rod, and the end disc is driven to move, the spring is deformed, and finally the plug plate is in contact with the surface of the plug rod. Under the action of force, the plug plate moves along the surface of the plug rod. When the plug plate slides into the slot on the surface of the plug rod, the spring recovers its deformation to pull the plug plate into the plug rod, limiting the plug rod, so that the plug rod drives the counterweight block to be stable. Under the action of the counterweight block, the weight of the fixed disc can be redistributed, so that the weight distribution of the fixed disc is uneven, which is convenient for the subsequent rotation of the rotary kiln. The driven rotation effect of the fixed disc can be improved, thereby driving the hollow shaft to rotate, and driving the crushing column, reinforcing plate, crushing rod, etc. to rotate, so as to crush the mixed material that is agglomerated and ringed inside the rotary kiln, so as to improve the roasting efficiency.

[0010] Furthermore, the length of the hollow shaft is equal to the effective roasting length of the rotary kiln. The hollow shaft is made of stainless steel. The setting of the hollow shaft can ensure the normal rotation of structural parts such as the crushing column and the reinforcing plate when the rotary kiln rotates subsequently, and the stainless steel material has good durability.

[0011] Furthermore, the length of the crushing column extending from the surface of the hollow shaft is 10 cm, the crushing column is equal to the radius of the fixed disc, and the crushing column is made of cast iron. Through the setting of the crushing column, the crystals and rings on the inner wall of the rotary kiln can be crushed and dispersed, and the cast iron material has good structural strength.
