Abstract

The utility model discloses an air nozzle with wobbling in vertical and horizontal two directions relating to the structure improvement of the air nozzle with wobbling in vertical and horizontal two directions. The back end (2-1) of the inner nozzle (2) of the utility model is positioned in the inner side of an outer nozzle (1). The exterior surface of the back end (2-1) of the inner nozzle (2) is spherical shape (2-2) in sliding connection with the inner side of the outer nozzle (1). The outer nozzle and the inner nozzle of the utility model are in sliding contact with the advantages of small interval, simple structure, low air resistance, flexible nozzle wobbling and reliable moving. The outer nozzle (1) and the inner nozzle (2) of the utility model can vertically wobble (+/-)30 degrees on the end opening of an air box and the inner nozzle (2) can horizontally wobble (+/-)30 degrees in the outer nozzle (1). The utility model can enlarge the adaptability on coal kinds to enable the coal with different coking performances and ignitability to burn in the same furnace to guarantee the smoke discharging of the furnace to obtain the standard of environment protecting and also provide an effective adjusting method for furnace adjusting.

Description

Vertically, the air nozzle of horizontal bidirectional swing

Technical field: the utility model relates to can be vertically and the improvement of the air nozzle structure of horizontal bidirectional swing.

Background technology: the air nozzle that is used for thermal power generation boiler generally can only be done horizontal or vertical unidirectional swing, makes the serviceability of boiler-burner have significant limitation.The patent No. is ZL01274292, the utility model patent that name is called " three-dimensional swing parallel flow burner nozzle " has solved air nozzle and can not do simultaneously up and down and the problem that swings, can regulate the height and the horizontal-shift at burner hearth internal combustion center, can improve the burning situation in the burner hearth, but there are three shortcomings in it, the one, nozzle is formed by two, makes structure become complicated and has increased the resistance of air; The 2nd, there is bigger space between nozzle and the intermediate, air scattering is more, has influenced the distribution of air vertical and level in burner hearth, has reduced the efficient of nozzle; The 3rd, horizontal hunting transmission device installing space is little, and operability is bad.

The utility model content: the purpose of this utility model is that development is a kind of vertically, the air nozzle of horizontal bidirectional swing, and it has simple in structure, and air drag is little, and the gap is little between outer nozzle (intermediate) and the inner nozzle, and nozzle oscillation is flexible, the characteristics of reliable in action.The utility model is made up of outer nozzle 1, inner nozzle 2, vertical oscillation bearing pin 3, horizontal hunting bearing pin 4, vertical oscillation pitman shaft 5, vertical oscillation connecting rod 6, horizontal hunting vertical connecting rod 7, horizontal hunting tranverse connecting rod 8, horizontal hunting pitman shaft 9, the tail end 2-1 of inner nozzle 2 is located at the inboard of outer nozzle 1, the outer surface of the tail end 2-1 of inner nozzle 2 is spherical 2-2, and the spherical 2-2 of the outer surface of the tail end 2-1 of inner nozzle 2 is connected with the inner slide of outer nozzle 1.Sliding-contact between the utility model outer nozzle and the inner nozzle, the gap is little between the two, has simple in structurely, and air drag is little, and nozzle oscillation is flexible, the advantage of reliable in action.

Description of drawings: Fig. 1 is a main TV structure schematic diagram of the present utility model, and Fig. 2 is that side of the present utility model is cutd open structural representation.

The specific embodiment: (seeing Fig. 1, Fig. 2) present embodiment is made up of outer nozzle 1, inner nozzle 2, vertical oscillation bearing pin 3, horizontal hunting bearing pin 4, vertical oscillation pitman shaft 5, vertical oscillation connecting rod 6, horizontal hunting vertical connecting rod 7, horizontal hunting tranverse connecting rod 8, horizontal hunting pitman shaft 9, the tail end 2-1 of inner nozzle 2 is located at the inboard of outer nozzle 1, the outer surface of the tail end 2-1 of inner nozzle 2 is spherical 2-2, and the spherical 2-2 of the outer surface of the tail end 2-1 of inner nozzle 2 is connected with the inner slide of outer nozzle 1.The both sides of outer nozzle 1 are fixed with vertical oscillation bearing pin 3, two vertical oscillation bearing pins 3 are connected with the port activity of bellows respectively, vertical oscillation connecting rod 6 is flexibly connected by vertical oscillation pitman shaft 5 and outer nozzle 1, one end of horizontal hunting vertical connecting rod 7 is connected with transmission device, one end of the other end of horizontal hunting vertical connecting rod 7 and horizontal hunting tranverse connecting rod 8 is hinged, and the other end of horizontal hunting tranverse connecting rod 8 is fixedlyed connected with the inboard of inner nozzle 2 by horizontal hunting pitman shaft 9.Horizontal hunting tranverse connecting rod 8 is provided with bar hole 8-1 with the link of horizontal hunting vertical connecting rod 7, and the horizontal hunting vertical connecting rod 7 hinged with bar hole 8-1 is provided with slide bar 7-1, and slide bar 7-1 is located in the bar hole 8-1 and slides in bar hole 8-1.

Outer nozzle 1 of the present utility model and inner nozzle 2 can be in port vertical oscillation ± 30 of bellows °, inner nozzle 2 can be in outer nozzle 1 horizontal hunting ± 30 °; Decapacitation enlarges the adaptability to coal, and the coking capacity coal different with ignitability can be burnt on same boiler, guarantees that the smoke evacuation of boiler reaches outside the environmental protection standard, can also provide a kind of extremely effectively debugging method to the boiler debugging.
