Maintenance of ceramic fiber blanket of thermal insulation layer in tunnel kiln drying chamber

The thermal insulation layer ceramic fiber blanket in the tunnel kiln drying chamber is an indispensable setting to maintain the temperature in the tunnel drying chamber to reduce heat loss and make the drying process proceed normally. If there are no insulation layer ceramic fiber blanket, the drying effect is poor, or the drying cannot be carried out.

a-When overhauling the ceramic fiber blanket of the thermal insulation layer, first check whether the waterproof layer on the surface of the drying chamber is cracked or damaged.

b-Secondly, analyze the cause of crack damage and the degree of damage.

c-Third, the cracks in the waterproof layer are treated to prevent rainwater from penetrating into the ceramic fiber blanket of the thermal insulation layer.

d-Fourth, for the damaged part, check whether the bottom insulation layer ceramic fiber blanket is damaged, and the damaged insulation layer ceramic fiber blanket should be reinstalled. The thermal insulation layer that has been eroded by water should be checked to see if its thermal insulation performance is good. If it has lost thermal insulation performance, it should be replaced. After the ceramic fiber blanket of the thermal insulation layer is re-installed, the top should be redone with waterproof treatment.

Maintenance of tunnel kiln drying room track: whether the track is straight or not is very important for the tunnel drying room, because the drying car that has stacked the bricks runs forward on the track, and the bricks are connected to the top and side walls of the drying chamber. The distances are relatively close. Once the track is bent or uneven, it is likely to cause the brick on the drying car to collide with the top or side wall of the drying chamber, which will damage the brick at light level, and cause the blank on the drying car to collapse or cause damage. The drying truck is stuck in the tunnel drying chamber, so that the production cannot be carried out normally. Therefore, after completing the maintenance of the ceramic fiber blanket of the insulation layer of the drying room, it is also necessary to check whether the track is parallel, the distance between the track and the walls on both sides of the drying room, whether the track is uneven, the wear degree of the track and whether the bolts are firm, etc. In order to ensure the normal operation of the tunnel dry room.
