Problems solved by technology

Compared with the original technology, the device of this patent has made obvious progress, but there are the following main problems: In order to adapt to the horizontal swing and vertical displacement, it is difficult to seal reliably between the rigid inner and outer spherical bodies, resulting in serious air leakage and pressure loss. Obviously, the ideal cooling effect cannot be achieved
In addition, the manufacture and assembly of hollow ball joints are relatively difficult, and the bellows are stretched and twisted during operation, so fatigue damage cannot be avoided

Embodiment 1

[0015] The deflection joint used for the grate cooler in this embodiment is as follows: figure 1 As shown, first look at the basic structure of its lower end: the lower end of the bellows 7 is fixedly connected to the lower inner ring plate 4 through the lower connecting pipe 20, the lower inner ring plate 4 is fixedly connected to the lower inner end plate 35, and the lower inner end plate 35 passes through two The side coaxial radial hinge is connected with the lower outer end plate 1 to form a plane hinge pair. The lower outer end plate 1 is fixedly connected with the lower flange 24 through the lower outer ring plate 34 . The two ends of the flexible ring belt 15 are respectively fixedly connected to the ring belt support plate 16 through the sealing pressure plate 26, and then one end is fixedly connected to the lower outer ring plate 34 through the lower inner end pipe 25, and the other end is fixed to the lower inner ring plate 4 through the lower connecting pipe 20. c...

Embodiment 2

[0023] The basic structure of this embodiment is the same as that of Embodiment 1. The difference is that the hinge pair at the connection between the upper and lower inner end plates (35) and the upper and lower outer end plates (1) adopts self-aligning bearings, so that even if there is a certain range of three-dimensional relative displacement between the connected upper and lower equipment, Since the self-aligning bearing has two-dimensional freedom of motion, the deflection joint for the grate cooler in this embodiment can also maintain a good working condition.

Embodiment 3

[0025] This example image 3 As shown, its basic structure is the same as that of Embodiment 1. The difference also lies in the hinge connection relationship at the connection of the inner end plates. Seen from the bottom, this embodiment connects the lower inner end plate 35 and the lower outer end plate respectively through two pairs of radial universal hinge rings 1” with mutually perpendicular hinges. 1 connection to form a universal hinge pair with two-dimensional freedom of movement. The corresponding structure of the upper part of the bellows is the same, so it will not be described in detail. This can also play the same role as the self-aligning bearing.

Abstract

A flexible deflection section for grate-type cooler is composed of bellows, upper and lower internal annular plates, upper and lower internal end plates, hinges, upper and lower external end plates, upper and lower external annular plates, upper and lower flanges, and upper and lower flexible rings with sealing layer. Its advantages are no air leakage, no torsion of bellows, high cooling effect and long service life.

Description

technical field [0001] The invention relates to a deflection deflection joint for a cooler in the cement manufacturing industry, in particular to a deflection deflection joint for a grate type cooler for cement clinker heat exchange, and belongs to the technical field of cement manufacturing equipment. Background technique [0002] The function of the deflection deflection joint is to transport cold air. It is difficult to design because it needs to realize the reliable docking of the upper and lower equipment ports that have both horizontal swing displacement and vertical displacement during operation. According to the applicant's knowledge, the elastic connection structure with a certain degree of flexibility is mainly used in foreign countries at present, and its disadvantage is that it is easy to be damaged by fatigue. The latest domestic technology is represented by the application number 99229071.6, the application date is 1999.08.02, and the name is "Flexible deflecti...
