The vertical cooler is one of the hosts of the calcination active lime equipment. The lime produced by the calcination of the rotary kiln flows into the vertical cooler with the refractory material. The section of the cooler is square and has a center cooling hood and sub-chamber cooling hood, the hood is equipped with a pipe connected with an external fan, a discharge port is arranged at the bottom of the cooler, and the motor vibration unloader is arranged under each discharge port. The material is covered in the cooler hood, and the formation of a certain thickness of the material layer, the cooling wind blowing from the external fan, through the wind chamber into the hood, from the hood sprang after contact with the high temperature materials to complete the heat exchange, air cooling material. The role of the feeder gradually discharged from the cooler, the material heated by the air, directly from the kiln hood into the rotary kiln, as the secondary air for calcination.
Vertical coolers are widely used in building materials, chemical, metallurgical and other departments, with the rotary kiln matching. The equipment in the natural state, the tilt of 3.5% of the cylinder, in the low-speed rotation, the material from the cylinder at the high end of the feed, the material plate will continue to move up and down the material to move down, cooling the material from low end discharge.
The cooler mainly is composed of the cylinder body support device, the transmission device.
1. Cylinder body
The cylinder is made of high-quality carbon steel plate rolled into a number of sections, made by welding, the cylinder in addition to both ends of the length of about 1 meter, are staggered with angle-type lifting plate, high-end to prevent the material back to the material circle, spiral blade.
2. Support device
The support device means supports the full weight of the rotary drum and allows the cylinder to be placed on it safely and smoothly. There are mainly wheel, wheel, the base part of the composition, and the wheel is used to control the cylinder axial movement.
Finally, for the maintenance of vertical coolers, the daily usage of attention to keep the vertical cooling body clean, remove dirt and obstacles on the body, include some obstacles of inner machine, in strict accordance with the norms of operation, this will greatly reduce usage of the failure to extend its service life.
