A preheater inner cylinder hanging piece

Abstract

The invention relates to a novel preheater inner cylinder hanging piece. A hanging piece body is an arc folded plate. The upper end and the lower end of the hanging piece body are provided with connecting plates. The upper-end connecting plate is located on the outer side of a circular arc of the hanging piece body. The lower-end connecting plate is located on the inner side of the circular arc of the hanging piece body. The upper surface and the lower surface of each connecting plate are flush with the upper surface and the lower surface of the hanging piece body respectively. A vertical groove is formed in the middle of each connecting plate. The vertical grooves penetrate through the whole connecting plates in the thickness direction. The left side and the right side of the hanging piece body are respectively provided with a side plate. Grooves are formed in the connecting plates and the hanging piece body. The width, in the radial direction of the circular arc of the hanging piece body, of each groove is slightly larger than or equal to the thickness of one connecting plate. According to the novel preheater inner cylinder hanging piece, one single hanging piece can be conveniently combined into a complete preheater inner cylinder, and the defect that a traditional preheater inner cylinder is combined by various different types of hanging pieces is overcome, so that the number of manufacturing dies and reserve parts of building users is reduced to be the minimum, and economic benefits are greatly improved.

Description

technical field [0001] The invention relates to a hanging sheet, in particular to an inner cylinder hanging sheet of a preheater of a cement production line. Background technique [0002] The preheater is the equipment for material preheating in the new dry process cement production line. The material is fed from the top of the preheater and is heated when it meets the hot air flow from bottom to top during the downward movement, and then it is separated from the hot air flow after being collided with the cylinder by the centrifugal force in the cyclone, and the material is separated from the hot air flow by its own gravity. Enter the next stage preheater. [0003] The purpose of setting the inner cylinder in the cyclone is to improve the separation efficiency of the material and the hot air flow, and reduce the unnecessary circulation of the powdery material between the various cyclone cylinders. [0004] Common inner cylinder structures include integral type and hanging ...

AI Technical Summary

Problems solved by technology

[0005] Most of the existing hanger-type inner cylinders are made of a variety of different types of hangers, which makes the production, installation, use and maintenance of the hangers and the purchase and management of spare parts high, and the waste caused by this cannot be tolerated. ignore

At the same time, the structure of the existing hanging piece causes its hanging part to be generally exposed to the harsh environment of high temperature and high dust, so that the hanging part of the hanging piece is easily damaged and has a short life, thus affecting the normal operation of the inner cylinder

[0006] The working environment of the inner cylinder of the preheater is extremely harsh. The shape of the cylinder surrounded by the coupons isolates the high-speed flow of high-temperature and high-dust airflow inside and outside the cylinder. The coupons are always subject to strong abrasive wear. The service life of the hanging piece is generally less than one year
