Abstract
The utility model belongs to the field of air preheaters and provides a radial segmented sealing device for a rotary air preheater. The radial segmented sealing device is mainly characterized in that a sector plate of the rotary air preheater adopts a segmented sector plate; the inner end of the sector plate on the fixed section is fixedly connected with a rotor center shaft; the other end of the sector plate on the fixed section is movably connected with the sector plate on the moving sector; a supporting roller is arranged at the outer end of the sector plate on the moving section; an annular guide rail is arranged corresponding to the supporting roller; when a heat-insulating plate is deformed, the sector plate on the moving section can automatically track under the action of gravity so as to ensure that the clearance between the sector plate and a radial sealing plate always retains a cold state reserve value, effectively avoid serious air leakage due to deformation of a heat end and moving-static friction due to deformation of a cold end and ensure the normal operation of the equipment. The utility model has the advantages of simple structure and favorable sealing effect.
Description
Technical field
The utility model belongs to air preheater, relates to a kind of rotary regenerative air preheater radial segments sealing device.
Background technology
Rotary regenerative air preheater is able to extensive use in UTILIZATION OF VESIDUAL HEAT IN.But be in operation, owing to be subjected to variations in temperature, mushroom deformation can take place in its rotor dividing plate, and the gap during distortion between fanning strip and the apex seal can change, and it is big that the gap of hot junction fanning strip significantly becomes, and occurs seriously leaking out; Cold junction fanning strip gap significantly diminishes, even disappears, and the sound friction occurs, and air preheater can't normally be moved.
Summary of the invention
The inventor finds that existing rotary regenerative air preheater radial seal technology exists certain defective in production practices, through constantly exploring, purpose is to propose a kind of rotary regenerative air preheater radial segments sealing device, a technical solution difficult problem preferably.
The technical scheme that the utility model is taked is a kind of rotary regenerative air preheater radial segments sealing device of design, its structure comprises: the rotor center axle of rotary regenerative air preheater, the rotor dividing plate, apex seal, fanning strip, wherein fanning strip adopts the segmented fanning strip, set up canned paragraph fanning strip and active segment fanning strip separately, canned paragraph fanning strip one end and rotor center axle are fixedly connected, the other end flexibly connects mutually with the active segment fanning strip, the outer end of active segment fanning strip is provided with support roller, and corresponding outer wall at the rotor dividing plate with support roller is provided with ring-shaped guide rail.
The utility model is taked technique scheme, cold junction and hot junction fanning strip to rotary regenerative air preheater are improved, all adopt the segmented fanning strip, when the rotor dividing plate is subjected to variations in temperature generation mushroom deformation, the active segment fanning strip relies on the gravity effect, can be by support roller from motion tracking, cold conditions reserved value gap is kept in gap between assurance fanning strip and the apex seal all the time, thereby effectively avoid the hot junction distortion to produce the sound friction that distortion produces with cold junction of seriously leaking out, guarantee that rotary regenerative air preheater normally moves, have simple in structure, advantage of good sealing effect.
Description of drawings
Fig. 1 represents the structural representation of the utility model at rotary regenerative air preheater rotor cold conditions state;
Fig. 2 represents the structural representation of the utility model at the hot state of rotary regenerative air preheater rotor.
The specific embodiment
In conjunction with the accompanying drawings and embodiments, further specify concrete structure of the present utility model.
The embodiment of the utility model rotary regenerative air preheater radial segments sealing device, referring to Fig. 1, Fig. 2, its structure comprises: the rotor center axle 1 of rotary regenerative air preheater, rotor dividing plate 2, cold junction and hot junction apex seal 3, cold junction and hot junction fanning strip 4, wherein fanning strip 4 adopts two sections fanning strips, fixedly connected with rotor center axle 1 in the inner of canned paragraph fanning strip 4.1, the other end and active segment fanning strip 4.2 flexibly connect by bearing pin, and support roller 5 is established by connecting piece in the outer end of active segment fanning strip 4.2, on the outer wall of rotor dividing plate 2 with the support roller 5 corresponding ring-shaped guide rails 6 that are provided with.
