Description
Technical Field
[0001] The utility model relates to the technical field of rotary kilns, in particular to a rotary kiln feeding spiral device. Background Art
[0002] The rotary kiln, also known as the rotary calcining kiln or rotary kiln, is similar in appearance to a rotary bed and is a building material equipment. Depending on the materials being processed, rotary kilns can be divided into cement kilns, metallurgical chemical kilns, and lime kilns. As the production capacity of existing rotary kilns increases and the materials become unevenly dry, a very large torque is generated at the end of the conical cylinder, which can easily cause the spiral to become stuck. In severe cases, the motor stops at least three times a week, requiring three people to clean it for two hours, which is time-consuming and labor-intensive and delays production.
[0003] After searching, in the prior art, the Chinese patent with patent publication number CN217417125U discloses "a rotary kiln feeding screw device". The rotary kiln feeding screw device belongs to the technical field of rotary kiln, and includes a feeding bin and a screw feeder. The screw feeder includes a cylinder, a screw shaft with spiral blades installed, and a driving motor connected to the screw shaft. The screw shaft passes through the inner cavity of the cylinder and is arranged along the axis of the cylinder. The cylinder is provided with a feeding port and a feeding port. The feeding port is connected to the feeding bin through a flange. The feeding port is used to output the material in the screw feeder to the rotary kiln. A drying hot air blower is arranged at the feeding port, and the air supply duct of the drying hot air blower is connected to the feeding port. The purpose is to reduce the occurrence of feeding screw jamming accidents, reduce the risk of equipment damage, and thus improve production efficiency; but there are still the following defects:
[0004] (1) The existing rotary kiln is directly driven by a motor to rotate the screw shaft, which increases the torque and puts a heavy load on the motor and the rotating shaft, making them prone to damage.
[0005] (2) The existing rotary kiln uses a spiral plate to rotate and transport materials. The spiral plate has a large area. Although the material can be exposed to hot air during transportation, it is very easy to accumulate, causing uneven drying.
[0006] Therefore, we made improvements on this and proposed a rotary kiln feeding spiral equipment. Utility Model Content
