Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the different materials they process. A feeder is installed at the front end of the rotary kiln. The feeder generally includes two types: one is a push-type feeder, such as a rotary kiln sealed push rod feeder disclosed in patent CN209956898U, and the other is a chute feeder, such as a chute feeder for an industrial hazardous waste rotary kiln incinerator disclosed in patent CN204345657U.

[0003] At present, the push-type feeder includes a shell and a push cylinder. The shell is generally connected to the rotary kiln frame by welding, while the push cylinder is installed inside the shell and its extended state is as long as 4 to 6 meters. In addition, due to the limitations of equipment space and workshop space, it is very difficult and labor-intensive to dismantle and maintain the push cylinder. Furthermore, regarding the oil circuit of the push cylinder, the closed condition of the shell leads to obvious obstruction when observing the oil circuit of the push cylinder from the outside to the inside, which is not conducive to timely discovering the problem of oil leakage of the push cylinder. Secondly, considering the working environment of the rotary kiln, the shell is usually covered with a certain amount of dust and mud, which needs to be cleaned from time to time. At present, it is mostly achieved with the help of scrapers in the workshop. The cleaning effect of the scraper is not good and there is a lot of residue. Utility Model Content
