Description
Technical Field
The invention relates to the technical field of circular cooler equipment, in particular to a labyrinth type sealing structure of an air box of a circular cooler.
Background
The circular cooler is a key device for pellet production and is responsible for cooling the high-temperature oxidized pellets. Generally, the method comprises three to four cooling sections, wherein oxidized pellets at about 1000 ℃ are cooled by air blown by a cooling fan until the temperature of the oxidized pellets reaches about 50 ℃ (namely after passing through the four cooling sections), and then the oxidized pellets are conveyed to a finished product bin by a belt conveyor. The main structure comprises an upper cover, a revolving body and an air box, a cooling fan blows normal-temperature air into the air box, and due to the existence of air pressure, the normal-temperature air enters the upper cover of the circular cooler through a trolley gap on the revolving body and then through a high-temperature oxidation ball on the trolley. In order to save energy, the hot gas of the upper cover of the first cold section is connected into the kiln head of the rotary kiln, and the flue gas temperature of the upper cover of the second cold section is connected into the grate. Therefore, the equipment is cooling equipment, so the wind system is the key, if the sealing between the wind box and the repacking frame is not good, the cooling effect of the oxidized pellets is directly influenced, red pellets are produced, the belt is burnt, the rotating speed of the fan is increased, the power consumption is increased, and the pellet cost is influenced.
In the existing sealing structure, high-temperature-resistant sealing rubber is filled in a gap of 27mm between an air box and a reinstallation frame, and a newly installed sealing rubber strip is tightly attached to the reinstallation frame, so that friction is increased, further, the current of a motor driving the reinstallation frame to operate is increased, and the power consumption is increased; simultaneously because the laminating is tighter leads to rubber strip wearing and tearing aggravation, operating duration has been for a long time and has leaded to rubber and repacking frame to have the clearance, and the rate of leaking out increases, need adjust again so that scrap. The air leakage rate is increased due to the loose adhesion, so that the rotating speed of the air blower is increased, the current of the air blower is increased, and the power consumption is increased. Because every bellows head (for the direction of operation) all is equipped with the air distribution board, the platform truck leaks the material and scatters on the air distribution board, along with constantly gathering of leaking the material, gather after full to the extrusion of sealing rubber strip, the wearing and tearing of sealing rubber strip are aggravated more, long-pending material is extruded outside the bellows, influence the site environment, increase post and clean intensity, the cold machine of ring receives material mouth and a cold section position oxidation ball temperature and is up to 1000 degrees, air distribution board position gathers and leads to the scaling loss after ball contact rubber strip, for this reason, we propose a cold machine of ring bellows labyrinth seal structure.
