Abstract
The utility model discloses a pipe clamp fixing structure of a solid hanger rod of an external bed for a circulating fluidized bed boiler, comprising a solid hanger rod and a plurality of pipe clamps matched with bends on the heated surface of the external bed. The pipe clamps are respectively located above and below the elbows of the bends on the heated surface. Each pipe clamp comprises a clamp ring, a pipeline trough and an arc-shaped clamping piece which are integrally formed. The clamp rings of the pipe clamps are sleeved on the solid hanger rod and all clamp rings above the elbow of the bends on the heated surface are fixedly connected with the solid hanger rod. Circular rings are arranged between two adjacent clamp rings below the bends on the heated surface. All circular rings are sleeved on the solid hanger rod and welded fixedly with the clamp rings at both ends. The first clamp ring below the elbow of the bend on the heated surface is further fixedly welded with a positioning ring above. The positioning ring is fixedly welded with the solid hanger rod. The utility model can prevent abrasion caused by the pipe clamps and the solid hanger rod and avoid shutdown so as to guarantee the continuity of production and the service life of the device.
Description
Technical field
The utility model relates to a kind of solid suspension rod of CFBB external bed heating surface suspention and fixed structure of pipe clamp of being used for.
Background technology
Be provided with heating surface in the CFBB external bed of using at present, heating surface is made up of several bend pipes, feeds the steam that needs heating in the bend pipe; The heating surface bend pipe of external bed low-temperature space is suspended on the external bed top through solid suspension rod, and several pipe clamps are housed on solid suspension rod, and pipe clamp lays respectively at the elbow above and below of heating surface bend pipe; Each pipe clamp includes snap ring, pipeline draw-in groove and the arc card that is connected as a single entity, and the snap ring of all pipe clamps all is placed on the solid suspension rod, and snap ring and solid suspension rod are the gap and are provided with; The upper and lower of every heating surface bend pipe lays respectively between the pipeline draw-in groove and arc card of pipe clamp separately, thereby is positioned, but is not connected between pipe clamp and the solid suspension rod; During work, because the mobile and impact of high velocity vapor in the heating surface bend pipe adds that the bed material in the external bed is rolling of fluidisation shape; The capital makes the heating surface bend pipe produce vibration, vibrates on solid suspension rod thereby drive pipe clamp, and snap ring and solid suspension rod produce friction, bump; Cause snap ring and solid suspension rod to wear and tear each other, during the snap ring serious wear, the Oscillation Amplitude of heating surface bend pipe will increase; Snap ring breaks easily and causes the pipe group to disintegrate, and needs in time to shut down to change pipe clamp, the continuity that influence is produced; In case solid suspension rod serious wear, the weight that can't bear the heating surface bend pipe will cause collapsing of heating surface bend pipe; Must not on-line maintenance, shortened the service life of equipment.
The utility model content
The purpose of the utility model is the above-mentioned deficiency that exists to prior art; The solid suspension rod pipe clamp of a kind of CFBB external bed fixed structure is provided; It can prevent that pipe clamp and solid suspension rod from producing wearing and tearing, avoids shutting down, thereby guarantees the continuity of production and the service life of equipment.
For achieving the above object; The solid suspension rod pipe clamp of the CFBB external bed fixed structure of the utility model; Comprise solid suspension rod, several pipe clamps that cooperate with the interior heating surface bend pipe of external bed; Several pipe clamps lay respectively at the elbow above and below of heating surface bend pipe; Each pipe clamp includes snap ring, pipeline draw-in groove and the arc card that is connected as a single entity, and the snap ring of all pipe clamps all is placed on the solid suspension rod, it is characterized in that the snap ring of all elbow that is positioned at heating surface bend pipe tops all connects firmly with solid suspension rod welding; Between adjacent two snap rings below the elbow of heating surface bend pipe, be equipped with annulus; All annulus all are placed on the solid suspension rod and connect firmly with the snap ring welding at two ends, and first snap ring that is positioned at the elbow below of heating surface bend pipe also connects firmly with the locating ring welding of its top, and this locating ring also connects firmly with solid suspension rod welding.
During use, because all snap rings that are positioned at the elbow top of heating surface bend pipe all connect firmly with solid suspension rod welding, the snap ring that is positioned at the elbow below of heating surface bend pipe is connected as a single entity through annulus, locating ring and solid suspension rod; When the heating surface bend pipe produced vibration, solid suspension rod and its synchronous vibration can prevent that pipe clamp and solid suspension rod from producing friction, bump; Prevent to produce wearing and tearing; The snap ring that is positioned at the elbow below of heating surface bend pipe simultaneously is the gap setting with annulus and solid suspension rod, but the bigger thermal stress of generation between the two has been avoided in free wxpansion between them; Guaranteed the mechanical performance of solid suspension rod, the collapsing and shutting down of the face bend pipe that keeps from heat;
In sum, the utility model can prevent that pipe clamp and solid suspension rod from producing wearing and tearing, avoids shutting down, thereby guarantees the continuity of production and the service life of equipment.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
As depicted in figs. 1 and 2; The solid suspension rod pipe clamp of this CFBB external bed fixed structure; Comprise solid suspension rod 1, several pipe clamps 2 that cooperate with heating surface bend pipe 9 in the external bed, several pipe clamps 2 lay respectively at the elbow above and below of heating surface bend pipe 9, and each pipe clamp 2 includes snap ring 2a, pipeline draw-in groove 2b and the arc card 2c that is connected as a single entity; The upper and lower of every heating surface bend pipe 9 lays respectively between the pipeline draw-in groove 2b and arc card 2c of pipe clamp 2 separately; Thereby be positioned, the snap ring 2a of all pipe clamps 2 all is placed on the solid suspension rod 1, and all snap ring 2a that are positioned at the elbow top of heating surface bend pipe 9 all connect firmly with solid suspension rod 1 welding; Between the adjacent two snap ring 2a below the elbow of heating surface bend pipe 9, be equipped with annulus 3; All annulus 3 all are placed on the solid suspension rod 1 and connect firmly with the snap ring 2a welding at two ends, and first snap ring 2a that is positioned at the elbow below of heating surface bend pipe 9 also connects firmly with locating ring 4 welding of its top, and this locating ring 4 also connects firmly with solid suspension rod 1 welding.
During use, because all snap ring 2a that are positioned at the elbow top of heating surface bend pipe 9 all connect firmly with solid suspension rod 1 welding, the snap ring 2a that is positioned at the elbow below of heating surface bend pipe 9 is connected as a single entity with solid suspension rod 1 through annulus 3, locating ring 4; When heating surface bend pipe 9 produced vibration, solid suspension rod 1 and its synchronous vibration can prevent that pipe clamp 2 and solid suspension rod 1 from producing friction, bump; Prevent to produce wearing and tearing; The snap ring 2a and the annulus 3 that are positioned at the elbow below of heating surface bend pipe 9 simultaneously are provided with for the gap with solid suspension rod 1, but free wxpansion between them has avoided between the two, producing bigger thermal stress; Guaranteed the mechanical performance of solid suspension rod 1; Keep from heat the collapsing of face bend pipe 9, thus avoid shutting down the continuity that guarantees to produce and the service life of equipment.
