Description
Technical Field
The utility model relates to the technical field of feeding of ring coolers, in particular to a bulk conveying system of a ring cooler.
Background
The circular cooler is an important component device of a cooling system in the production process of pellets and sinter. The rotary body of the annular cooler is driven to rotate by a main motor, a speed reducer, an open gear and a chain wheel. Along with the rotation of the revolving body, the hot pellets and hot sinter produced in the previous process step continuously fall onto the trolley with the grate holes in the revolving body. Through the slow rotation of the trolley, the minerals are gradually cooled by cooling air introduced into the lower part of the trolley, and finally discharged to a discharge port to enter the next production link. In the cooling process, mineral bulk materials and dust fall into a wind box ash bucket at the lower part of the annular cooler from the grate holes of the trolley under the action of cooling wind.
It is known that the bulk material collecting devices most commonly used in the current circular cooler are bulk material trolleys and circular tape machines. The bulk material trolley is divided into a semi-automatic bulk material trolley and an automatic bulk material trolley. The semi-automatic bulk material trolley needs to be remotely operated on site by a person, and has poor working environment and high labor cost; the automatic bulk cargo trolley can realize full-automatic control, but has the problems of high investment cost, maintenance cost and spare part cost, and is easy to fail due to accurate control. The annular adhesive tape machine is a newly developed technology in recent years, can continuously operate and has low control requirement, but the annular adhesive tape machine has an open tape surface, is easy to generate dust, and still has the problems of high investment cost, maintenance cost and spare part cost. The two bulk material collecting devices have a common problem, and the air box ash bucket has a serious air leakage problem during unloading.
