Description
Technical field
The utility model relates to deduster field, specifically a kind of air-introduced machine exhaust pass installing blind plate additional.
Background technology
At present, be known in the boiler that there is multiple stage same model in power plant, and the air-introduced machine exhaust pass of boiler being connected on same horizontal flue.Stand-by boiler air-introduced machine exhaust pass plate is poorly sealed close, and the flue gas leaking through flue plugboard returns stand-by boiler internal corrosion air-introduced machine, electric precipitation and internal structure thereof.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, air-introduced machine exhaust pass installing blind plate additional that result of use is good.
The utility model solves the technical scheme that its technical problem adopts:
A kind of air-introduced machine exhaust pass installing blind plate additional, include outlet flue, two flanges are provided with at outlet flue place, frame mouth size in the middle part of flange matches with outlet flue, outlet flue and one of them flange are fixedly linked and are connected together, two flanges are connected by bolt, are provided with blind plate between two flanges, and the left end of blind plate is provided with trapezoidal projection.
Install an air-introduced machine exhaust pass for blind plate additional, the length of its blind plate is identical with the length of flange, and the width of blind plate is less than the distance between upper and lower two side through hole of flange, is greater than the width of frame mouth.
Install an air-introduced machine exhaust pass for blind plate additional, it is provided with two connection bumps in the left side of blind plate, and connection bump is arranged between the through hole on the left of flange.
Compared with prior art, the beneficial effect produced is the utility model:
The utility model has reasonable in design, the feature such as structure is simple, easy to use, function admirable, practicality, can block the flue gas leaking through flue plugboard and return boiler internal, avoid flue gas corrosion air-introduced machine, electric precipitation and internal structure thereof.
Accompanying drawing explanation
Accompanying drawing 1 is forward sight structural representation of the present utility model;
Accompanying drawing 2 is plan structure schematic diagrames of the present utility model.
In figure: 1, trapezoidal projection, 2, connection bump, 3, blind plate, 4, flange, 5, through hole, 6, frame mouth, 7, outlet flue.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail below.
As shown in drawings, the air-introduced machine exhaust pass installing blind plate additional of the present utility model, its structure includes outlet flue 7, outlet flue 7 place is provided with two flanges 4, frame mouth 6 size in the middle part of flange 4 matches with outlet flue 7, and outlet flue 7 and one of them flange 4 are fixedly linked and are connected together, and two flanges 4 are connected by bolt, be provided with blind plate 3 between two flanges 4, the left end of blind plate 3 is provided with trapezoidal protruding 1.The length of blind plate 3 is identical with the length of flange 4, and the width of blind plate 3 is less than the distance between flange about 4 two side through hole 5, is greater than the width of frame mouth 6; Be provided with two connection bumps 2 in the left side of blind plate 3, connection bump 2 is arranged between the through hole 5 on the left of flange 4.
Make two flanges according to the size of air-introduced machine exhaust pass, be welded on air-introduced machine exhaust pass.Between two flanges, install a stainless-steel sheet additional, with connecting bolt, two flanges and stainless-steel sheet are tightened together.Flue is cut open, the flange welding connected on flue.With connecting bolt, flange and stainless-steel sheet are tightened together when boiler is for subsequent use; Boiler opens stokehold and corrosion resistant plate is extracted out, and then two flanges with bolted together.
Its processing and fabricating of air-introduced machine exhaust pass installing blind plate additional of the present utility model is simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characteristic described in description, be the known technology of those skilled in the art.
