Embodiment

[0012] The cement preheater inner tube hanging piece of the present embodiment, such as figure 1 As shown, the hanger is S-shaped with a center symmetry, and its upper half includes the upper arm 1 and the upper hook 2 extending from the top of the upper arm 1 to one side of the hanger; the lower half of the hanger includes the lower arm 3 and the lower arm 3. 3. The lower hook 4 extending from the bottom end to the other side of the hanging piece.

[0013] The coupon in this embodiment is made of a heat-resistant steel, and its composition is as follows: Ni: 10%; Cr: 26%; Si: 1.4%; C: 0.35%; Mo: 0.4%; W: 0.4%; Mn: 1%; N: 0.14%; Re: 0.005%; the balance is iron. The heat-resistant steel used in this embodiment uses carbon, nitrogen and a small amount of nickel as austenite elements to form an austenite matrix. In this embodiment, higher carbon elements are added to expand and stabilize the austenite and reduce the nickel content. At the same time, due to the carbide dispersi...

Abstract

The invention relates to a cement preheater internal cylinder hanging sheet and belongs to the technical field of cement production equipment. The hanging sheet is S-shaped symmetrical to the center. The upper half portion of the hanging sheet comprises an upper arm and an upper hook extending towards one side of the hanging sheet from the top end of the upper arm. The lower half portion of the hanging sheet comprises a lower arm and a lower hook extending towards the other side of the hanging sheet from the bottom end of the lower arm. Due to the fact that the cement preheater internal cylinder hanging sheet is S-shaped symmetrical to the center, no gap exists after combination of hanging parts, the wind speed is increased, and therefore the production of cement is improved greatly; furthermore, the gapless structure can ensure that the hanging parts are not affected by wind, and therefore the service life is prolonged. In actual tests, the service life can reach more than 1.5 times that of an original structure.

Description

technical field [0001] The invention relates to a hanging piece of an inner cylinder of a cement preheater, belonging to the technical field of cement production equipment. Background technique [0002] At present, the hanging pieces of the inner cylinder of the cyclone in cement production are all straight arm type. Such a structure makes gaps exist at the joints of the hanging pieces, and the gaps will weaken the wind speed and affect the service life of the hanging pieces. Contents of the invention [0003] The technical problem to be solved by the invention is to propose a preheater inner tube hanging piece without a gap at the junction. [0004] The technical solution proposed in order to solve the above-mentioned technical problems is: a cement preheater inner cylinder hanging piece, the hanging piece is in the shape of a center symmetrical S, the upper half of which includes the upper arm and the hanging piece at the top of the upper arm. The upper hook extending ...
