Embodiment 1
[0035] Such as Figure 1~4 As shown, a strengthened inner cylinder for a cement preheater in this embodiment includes a reinforcement plate 110, an outer layer castable 101 and an inner layer castable 102, and the outer layer castable 101 and the inner layer castable 102 are respectively arranged on the reinforcement plate 110 on both sides. The reinforcement plate 110 mainly plays a role in maintaining the overall strength of the inner cylinder in the structure of the inner cylinder, thereby better maintaining the overall shape of the inner cylinder; in this embodiment, the reinforcement plate 110 is a steel plate, but the material of the reinforcement plate 110 is not limited to Steel plate, any material that can play a better internal shape support role can be used. The outer castable 101 and the inner castable 102 are generally refractory materials, which are in direct contact with the hot air in the cement preheater.
[0036] The reinforcing plate 110 is provided with a...

Abstract
The invention discloses a strengthened internal cylinder for a cement preheater, and belongs to the technical field of cement production devices. The strengthened internal cylinder comprises a reinforcing plate, an outer-layer castable and an inner-layer castable, and the outer-layer castable and the inner-layer castable are arranged on the two sides of the reinforcing plate respectively; and multiple through holes are formed in the reinforcing plate and penetrate through the two sides of the reinforcing plate. The outer-layer castable and the inner-layer castable are connected through the through holes, so that the outer-layer castable and the inner-layer castable are integrated into a whole, and the bonding strength of the outer-layer castable and the inner-layer castable on the reinforcing plate.
Description
technical field [0001] The invention relates to the technical field of cement production equipment, and more specifically relates to a reinforced inner cylinder for a cement preheater. Background technique [0002] In the cement production industry, the inner cylinder of the preheater is an important equipment to ensure the normal production of cement. In the preheater of the rotary kiln for cement production, the preheater needs to provide multi-stage co-current heat exchange for the raw meal powder and the hot air at the kiln tail The raw material powder finally enters the rotary kiln for calcination, and the inner cylinder can provide sufficient dispersion time for the raw material powder. During this process, the working condition of the inner cylinder is very harsh, and it faces high temperature, alkali steam, sulfur steam and high-speed erosion of the powder. . [0003] At present, most of the inner cylinders of the existing preheaters are hanging plate type, and the ...
