Abstract
The utility model provides an oblique flue, which comprises an oblique flue main body. The oblique flue is characterized in that two ends of the oblique flue main body are respectively provided with a first non-metal expansion joint and a second non-metal expansion joint, at least one supporting base is arranged on the middle portion of the oblique flue main body, and the oblique flue main body is further provided with at least one limiting device. The oblique flue has the advantages that the oblique flue is simple and reliable in structure, can be connected with a boiler back flue and an air preheater and absorbs expansion between the boiler back flue and the air preheater.
Description
Technical field
The utility model relates to a kind of oblique flue, belongs to the boiler technology field.
Background technology
Tiltedly flue is between boiler economizer ash bucket and air preheater, is used to connect cigarette well and air preheater behind the boiler and absorbs the two expansion.Common oblique flue often adopts overhung construction, and tiltedly flue main body two ends are connected with other flue by the expansion of metal joint, and tiltedly the weight of flue is suspended on the steel construction by two suspension rods.There is following several respects problem in this arrangement form of common oblique flue: 1, tiltedly flue weight is only born by two suspension rods, and every suspension rod need be shared more than 20 ton load, and is therefore all higher to the requirement of suspension rod, steelframe and connector.2, the structure of 2 suspentions need accurately calculate the position of centre of gravity of oblique flue, otherwise can cause reversing of oblique flue because of the off-centre of point of suspension.3, consider the expansion of boiler, tiltedly the suspension centre of flue must be provided with a spring hanger at least, thereby increases design cost.4, the conduction of external applied load (wind load, seismic (seismal etc.) need be delivered on other flue by the expansion of metal joint at two ends about the oblique flue main body, and tiltedly the structure of flue is independent, has interaction with other flue.
Summary of the invention
The purpose of this utility model provides a kind of flue simple in structure, reliably oblique.
In order to achieve the above object, the technical solution of the utility model provides a kind of oblique flue, comprise oblique flue main body, it is characterized in that, tiltedly the two ends of flue main body are respectively equipped with first non-metal expansion joint and second non-metal expansion joint, tiltedly the middle part of flue main body is provided with at least one bearing, also is provided with at least one stopping means on the described oblique flue main body.
The utility model has the advantages that simple in structurely, reliable, can connect cigarette well and air preheater behind the boiler and absorb the two expansion.Tiltedly the weight of flue can be assigned on a plurality of bearings simultaneously, and the load that each bearing bears is less, and needn't accurately calculate the position of centre of gravity of oblique flue.It is relatively independent that the setting of stopping means makes the structure of oblique flue in addition, avoided the interaction with other flue.
Description of drawings
Fig. 1 is a kind of oblique flue structure schematic diagram;
Fig. 2 is a kind of oblique flue side view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be a kind of oblique flue structure schematic diagram, described oblique flue is made up of first non-metal expansion joint 1, second non-metal expansion joint 2, bearing 3, first stopping means 4, second stopping means 5 and oblique flue main body 6.
Tiltedly flue is vertically arranged, tiltedly the two ends of flue main body 6 are respectively equipped with first non-metal expansion joint 1 and second non-metal expansion joint 2, first non-metal expansion joint 1 and second non-metal expansion joint 2 respectively with the turning flue be connected flue and be connected. as shown in Figure 2, be oblique flue side view, tiltedly the middle part of flue main body 6 is provided with four bearings 3, tiltedly the weight of flue is supported on the boiler steelframe 7 by bearing 3, be respectively equipped with four first stopping means 4 and four second stopping means 5 on the described oblique flue main body 6, described first stopping means 4 is located at respectively on the same plane with the tie point of oblique flue main body 6, described second stopping means 5 is located at respectively on the same plane with the tie point of oblique flue main body 6, the center line of the center line of one first stopping means 4 and one second stopping means 5 respectively with the boiler central lines, with the Expansion Center of setting oblique flue with transmit external applied load.
