Description
Technical field
The utility model relates to dust anti-block apparatus, is specifically related to economizer anti-block apparatus.
Background technology
Due to environmental requirement increasingly stringent now, a lot of power plant has carried out the denitration transformation of equipment, and this is wherein just included in below economizer hopper and installs the defeated grey equipment of economizer.The general particle of ash of the defeated grey equipment conveying of economizer is comparatively large and ash content is thicker; cause the large-size massive thing often having coking or caking in economizer hopper thus; once these large-size massive things enter into ash conveying pipe, be easy to cause conveying equipment plugging, deal with very difficult.Particularly at present a lot of economizer ash discharging pipe be all save by ordinary telescopic to be connected between the pump of storehouse, large-scale foreign matter enters into defeated ash silo pump easily via telescopic joint, cause defeated grey time foreign matter and ash content enter into ash conveying pipe simultaneously, cause line clogging.In addition, the foreign material left over after overhaul of the equipments also often can enter into conveying equipment, and the time has grown the serious accident that economizer hopper may be caused to cave in.
Utility model content
Technical problem to be solved in the utility model is the problem that plugging easily occurs for the ash-transmission system of existing economizer.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of economizer anti-block apparatus, comprise the deashing device be arranged on telescopic joint, described telescopic joint be axially provided with the upper flange and lower flange arranged up and down, the two ends up and down of described telescopic joint are connected to the lower ash bucket of economizer and defeated grey equipment, described deashing device comprises screen pack, it is arranged between described upper flange and described lower flange, and the lumen segmentation of described telescopic joint is become upper and lower two parts by described screen pack.
In such scheme, described deashing device also comprises plate, the cross section of described telescopic joint is provided with the chute holding described plate, described chute is arranged at the top of described upper flange, described plate slides and is arranged in described chute, and after described plate inserts described chute, the cross section of described telescopic joint covers by described plate.
In such scheme, the outer peripheral face of described telescopic joint is provided with opening, described opening is arranged between described upper flange and described chute, described deashing device also comprises draws apparatus for ash, described one end of drawing apparatus for ash is shaft-like and is piercing in the outside of described opening, described in draw apparatus for ash the other end be hook-shaped or rake and slide and be arranged at the inner side of described opening.
In such scheme, the outer surface of described telescopic joint is provided with temperature-detecting device.
In such scheme, the vertical interval of described screen pack and described upper flange is 10 millimeters.
In such scheme, described in draw apparatus for ash and described upper flange vertical interval be 50 millimeters.
The utility model, screen pack is provided with between the upper flange and lower flange of telescopic joint, can large-scale foreign matter be blocked on screen pack, manual-lock plate afterwards, then open and draw apparatus for ash and can take out foreign matter easily, efficiently solve the problem blocking ash-transmission system after larger foreign matter enters into economizer ash conveying pipe and cannot process, know-why is simple and clear, and cost is lower, greatly reduce the maintenance workload of maintainer, have great facilitation to the safe operation of system equipment.
Accompanying drawing explanation
Fig. 1 is appearance schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail.
As shown in Figure 1; the economizer anti-block apparatus that the utility model provides; comprise the deashing device be arranged on telescopic joint 1; telescopic joint 1 can adopt prior art; wherein telescopic joint 1 be axially provided with the upper flange 9 and lower flange 10 arranged up and down; upper flange 9 and lower flange 10 are for the protection of telescopic joint 1 deformation within the specific limits, and the two ends up and down of telescopic joint 1 are connected to the lower ash bucket 2 of economizer and defeated grey equipment 3.
Deashing device comprises successively: screen pack 4, plate 5 and draw apparatus for ash 7, wherein screen pack 4 is arranged between upper flange 9 and lower flange 10, and screen pack 4 covers the cross section of telescopic joint 1, the lumen segmentation of telescopic joint 1 is become upper and lower two parts, so play the effect of blocks dust and foreign matter.Wherein screen pack 4 and the vertical interval of upper flange are for being preferably 10 millimeters, and the aperture of screen pack 4 is preferably set to 30 millimeters, and the material of screen pack 4 adopts nickel alloy to make.
The mounting means of plate 5 is: the cross section of telescopic joint 1 is provided with the chute 6 for holding plate 5, chute 6 is arranged at the top of upper flange 9, plate 5 slides and is arranged in chute 6, and after plate 5 inserts chute 6, the cross section of telescopic joint 1 can cover by plate 5 completely, so just blocks dust can continue to drop on screen pack 4, is convenient to cleaned filter screen 4, after cleaning out, more manually pull-out plate 5 can continue to use.
The mounting means drawing apparatus for ash 7 is: on the outer peripheral face of telescopic joint 1, be provided with an opening, opening is arranged between upper flange 9 and chute 6, the one end of drawing apparatus for ash 7 is shaft-like and is piercing in the outside of this opening, the other end is hook-shaped or rake and slide and be arranged at the inner side of this opening, like this, during use, Non-follow control draws shaft-like one end of apparatus for ash 7, by one end that is hook-shaped or rake, just can say and be drawn out by the dust stratification remained on screen pack 4.Draw apparatus for ash 7 and be preferably 50 millimeters with the vertical interval of upper flange 9, draw apparatus for ash 7 and can adopt and of the prior artly draw rake, structure is simple, with low cost.
The outer surface of telescopic joint 1 is provided with temperature-detecting device 8, temperature-detecting device 8 can adopt DCS temperature controller of the prior art to carry out Long-distance Control to economizer, once the top of telescopic joint 1 causes dust stratification cannot fall in defeated grey equipment 3 because blocking, temperature directly can be down to environment temperature from high temperature.At this moment can manual-lock plate 5 open and draw apparatus for ash 7 and take out foreign matter, overall process realizes simple and convenient and is easy to operation.
