Abstract
The utility model relates to a buffer device for an alumina flash drum, which comprises a wear-resistance cone (11) and a buffer support frame (12) arranged under the wear-resistance cone (11), wherein the buffer support frame (12) is coiled into a whole body by a plate-shaped component, and the side wall of the buffer support frame (12) is provided with a plurality of material discharge holes (13). When the buffer device of the utility model is used, under the huge impact of slurry at a material outlet, the support frame coiled into the whole body does not have the defect that the existing support frame can not discharge material discharge due to the material discharge opening blockage by slurry scattered at the material discharge opening because of the welding seam cracking. In addition, the material slurry in the whole drum does not need to be completely discharged for replacement through drum entering in order to restore the damaged support frame. The utility model greatly reduces the overhaul times and the machine halt times, and ensures the normal operation of the system.
Description
Technical field
The utility model relates to a kind of buffer unit, is specifically related to a kind of aluminium oxide flash tank buffer unit.
Background technology
In alumina producing, the high pressure stripping is a procedure of most critical, and flash tank is one of key equipment of high pressure stripping.The effect of flash tank be with the material after high temperature, the high pressure stripping through after some grades of flash distillations, make material fully discharge secondary vapour, secondary vapour is used for the heating of low-temperature zone material, makes the process that temperature of charge and pressure are minimized.
Flash tank is made up of venthole 1, cylindrical shell 2, charging aperture 3, buffer unit 4, discharging opening 5, discharge nozzle 6 etc. as shown in Figure 1.High temperature, high-pressure material are sprayed in the groove by charging aperture 3, and the lower end of charging aperture 3 is provided with buffer unit 4, and the material of the high pressure of coming in is played cushioning effect.Shown in Fig. 2 a, b, buffer unit 4 is made up of wear-resisting awl 41 and support 42, and support 42 is welded by three channel-section steels, and support is fixed by welding on low head 21 bottom surfaces, and the high pressure slip is sprayed directly on on the wear-resisting awl 41.Enter next procedure by the material after the flash distillation from discharging opening 5 outflows.
Because of material pressure is bigger, generally about 4.0Mpa, the impulsive force to buffer unit 4 during charging is very big, causes welding support 42 welding seam breakings, and three channel-section steels are scattered, and channel-section steel is trapped in discharge gate 5, makes normally discharge of discharge gate 5, causes certain difficulty to maintenance.
The utility model content
The purpose of this utility model just is to provide a kind of aluminium oxide flash tank buffer unit, to solve above-mentioned defective of the prior art.
For achieving the above object, the technical solution of the utility model is to adopt a kind of aluminium oxide flash tank buffer unit, comprises wear-resisting awl and is located at wear-resisting buffering stand of boring the below, and described buffering stand is rolled by plate-shaped member and forms, and its sidewall is provided with some relief holes.
Preferably, described buffering stand rolls into cone shape, and conehead one end of this cone shape is connected with described wear-resisting awl, and the other end relative with described conehead is connected with the low head of aluminium oxide flash tank.
Preferably, described relief hole is provided with three.
Preferably, described three uniform settings of relief hole.
Preferably, described relief hole is provided with more than three or three.
Preferably, described plate-shaped member is a steel plate.
Use buffer unit of the present utility model, under the enormous impact of discharging opening slip, roll into whole support and can owing to weld cracking is scattered in discharge gate, not stop up discharge gate as support in the past, can't discharge.And need not in order to recover impaired support, the slip of the whole groove of emptying enters in the groove and changes.The utility model has significantly reduced the maintenance number of times and has shut down number of times, has guaranteed the normal operation of system.

The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As Fig. 3 a, shown in the b, the aluminium oxide flash tank buffer unit of present embodiment comprises wear-resisting awl 11 and the buffering stand 12 that is located at wear-resisting awl 11 belows, and wherein, buffering stand 12 is rolled by plate-shaped member and forms, and its sidewall is provided with some relief holes 13.
Preferably, buffering stand 12 rolls into cone shape, and conehead one end of this cone shape is connected with wear-resisting awl 11, and the other end relative with described conehead is welded on the low head 21 of aluminium oxide flash tank.
And preferably, relief hole 13 is provided with three, and uniform setting.
Preferably, relief hole 13 is provided with more than three and three.
Preferably, above-mentioned plate-shaped member is a steel plate.
When the buffer unit of present embodiment is installed to the aluminium oxide flash tank, pass through, arbitrary hole in some relief holes 13 and discharge nozzle direction are consistent, so that the insertion of discharge nozzle for the ease of slip.
Use buffer unit of the present utility model, under the enormous impact of discharging opening slip, roll into whole support and can owing to weld cracking is scattered in discharge gate, not stop up discharge gate as support in the past, can't discharge.And need not in order to recover impaired support, the slip of the whole groove of emptying enters in the groove and changes.The utility model has significantly reduced the maintenance number of times and has shut down number of times, has guaranteed the normal operation of system.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, those of ordinary skill in the art can expect some identical, replacement schemes apparently, and these schemes all should fall into the scope of the utility model protection.
