Abstract
The utility model discloses a hanging piece of a preheating device. The hanging piece of the preheating device comprises an upper hanging piece, a lower hanging piece and a fastening bolt. Grooves are formed in the upper hanging piece and the lower hanging piece. A connecting hole is arranged between the upper hanging piece and the lower hanging piece. The fastening bolt is arranged on a connecting hole position of the upper hanging piece and the lower hanging piece. The hanging piece of the preheating device is novel in design and easy to use. In time of use, the bolt is loosened, the upper hanging piece and the lower hanging piece are hung on corresponding positions and finally, the bolt is screwed tightly. Thus, the hanging pieces do not deform. In time of dismantling, the fastening bolt is dismantled for finishing dismantling the hanging pieces. The preheating device can be conveniently installed and dismantled. The hanging piece of the preheating device is prevented from deforming in time of installation.
Description
Technical field
The utility model belongs to mechanical field, particularly a kind of preheater lacing film.
Background technology
Preheater is exactly that the fin of flue gas by inside in the boiler back end ductwork will enter air preheat before the boiler to the heating surface of uniform temperature.Be used for improving the heat exchange performance of boiler, reduce energy consumption.Generally abbreviate air preheater as.The coal-burning boilers that are used for more.Application in boiler is generally three warehouse separated types.Air preheater slowly rotates during use, and smoke inlet and air intake are constant.Flue gas is discharged after entering the fume side of air preheater, has absorbed the fin of flue gas heat in the air side that is rotated down to of air preheater, with the heat transferred air.The inner core lacing film is because material differs, the coefficient of expansion does not wait, serviceability temperature each side factor such as transfinite in addition, general in various degree distortion, damage are arranged, phenomenon such as collapse ftractures, drops, this will cause gas solid separation rate and material resolution ratio to reduce, heat loss increases, yield and quality seriously descends, very person's system jams.Like this; the installation and removal of preheater lacing film are convenient just extremely important, but all inconvenient some preheater lacing film installation and removal the time, are easy to make when installing the lacing film distortion; particularly use later and be out of shape, corrode through regular meeting, can be more difficult in the time of dismounting.
The utility model content
The purpose of this utility model namely produces thus, proposes a kind of a kind of preheater lacing film very easily that uses and install.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of preheater lacing film comprises lacing film, following lacing film and trip bolt.The described lacing film of going up is provided with groove with following lacing film, and the centre has connecting hole, and described trip bolt is in the connecting hole position of last lacing film and following lacing film.
The utility model design is unique, uses simply, and Panasonic's screw during use will be gone up lacing film and following lacing film then and hang over the relevant position, at last at trip bolt, like this can not make the lacing film distortion; As long as trip bolt is disassembled, made things convenient for the installation and removal of preheater lacing film in the time of dismounting, prevented when installing it being the distortion of preheater lacing film.
Description of drawings
Fig. 1 is the utility model side view.
Fig. 2 is the utility model schematic appearance.
Wherein: the last lacing film of 1-, lacing film under the 2-, 3-trip bolt, 4-connecting hole, 5-groove.
The specific embodiment
By reference to the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1 and Figure 2: a kind of preheater lacing film comprises lacing film 1, following lacing film 2 and trip bolt 3.Describedly go up lacing film 1 and following lacing film 2 is provided with groove 5, the centre has connecting hole 4, and described trip bolt 3 is on the connecting hole of last lacing film 1 and following lacing film 24.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although the utility model book has been described in detail with reference to above-mentioned the utility model of each embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (2)
1. a preheater lacing film comprises lacing film, following lacing film and trip bolt, it is characterized in that being: the described lacing film of going up is provided with groove with following lacing film, and described trip bolt is in the connecting hole position of last lacing film and following lacing film.
