Description

Technical Field

[0001] The utility model relates to the technical field of kiln mouths, in particular to a kiln mouth using titanium-aluminum ceramic composite prefabricated parts. Background Art

[0002] The kiln mouth of a cement kiln usually refers to the entrance or exit of a cement kiln. A cement kiln is a device used to produce cement, where raw materials are calcined and turned into cement clinker. The kiln mouth usually includes a feed port and a discharge port. Raw materials are added through the feed port, and cement clinker is produced through a high-temperature reaction in the cement kiln, which is then discharged through the discharge port.

[0003] At present, cement kiln mouths usually use heat-resistant steel castings. During long-term use, the heat-resistant steel castings are severely burned and need to be replaced regularly. The material cost of heat-resistant steel castings is high, and each time the castable is replaced, there is cross-operation, which poses a safety risk. Utility Model Content

The lower fixing frame is fixed to the kiln body through the fixing holes of the two fixing plates using bolts or other tools, and the cement material discharged from the kiln body is discharged from the movable holes of the lower fixing frame and the upper fixing frame.

[0007] Preferably, the tops of the two screw rods are both provided with hand wheels, and the two screw rods can be rotated using the two hand wheels.

[0008] Preferably, a distance is left between the two hand wheels and both sides of the upper fixing frame so that when the two hand wheels are rotated, no interference is generated with the upper fixing frame.

[0009] Preferably, fixing rods are welded on both sides of the bottom of the upper fixing frame, and fixing grooves are opened on both sides of the top of the lower fixing frame, and the two fixing rods are respectively inserted into the two fixing grooves. The upper fixing frame and the lower fixing frame are movably connected through the fixing rods and the fixing grooves.

[0010] Preferably, the lower fixing frame is welded with fixing plates on both the front and rear sides, and both fixing plates are provided with fixing holes. The lower fixing frame is fixed to the kiln body using tools such as bolts through the fixing holes of the fixing plates.

[0011] Preferably, the lower fixing frame and the upper fixing frame are provided with movable holes through which the cement material in the kiln body can be discharged.
