Operation and Maintenance of Vertical Cooler

The vertical cooler is the main supporting equipment of the ceramic firing system. It not only plays the role of cooling and conveying the hot material, but also is the key equipment in the heat recovery of the fired ceramic bricks. The cooler has the advantages of simple structure, less movable parts and low maintenance. This structure of the cooler strengthen the gas-solid heat exchanger, so that the building has been rapid cooling ceramic particles, so that not only improve the secondary air temperature into the kiln, but also improve the heat recovery.

First, the working principle:
The material calcined by the rotary kiln falls from the kiln head into the shell with the lining castable. More than 100mm sintered bulk material is stored in the upper part of the grate bar, discharged from the dumping roller and discharged through the grate plate. Cooler body, the material in the process of falling by the centrifugal blower into the lower part of the cooler of the natural wind through the upper and lower air chamber main cold hood, four sub-room hood rolling to cool the material, the wind from the natural wind into hot air into the rotary kiln to help fuel combustion, cooling material in the process of cooling the body to stay in the body for some time, and the cooler body connected to the bottom of the four slip tube bottom equipped with four electromagnetic vibrating feeder, when the material in the temperature dropped to above 60 ℃ , By the control system to control the work of electromagnetic vibration feeder, the material unloaded, conveyed by the chain plate conveyor pass to the next process. Material storage process of heat also will enter the rotary kiln, saving energy, reduce pollution and achieve environmental protection.

Second, the composition:
The vertical cooler is composed of the kiln head cover, the kiln head sealing device, the grate plate device, the pouring roller, the cooler main body, the lower cooling wind room, the hood device, the vibration discharging device, the discharging funnel and the secondary air blower.

Third, the vertical cooler operation and maintenance:
1. Perform safe operating procedures.
2. Electromagnetic vibration Feeder hook wear.
3. Whether electromagnetic vibration Feeder amplitude is stable or not, put an end to the phenomenon of running material.
4. Finished product transport system failure, the system cannot normally transport the material, you can stop the material in the cooler for short-term storage of materials.
5. Do a good job of maintenance, put an end to leaking.
6. Through the kiln head of the fire hole and check the door regularly check the kiln discharge situation.
