Abstract
An elongated retractable soot blower for a negative-pressure boiler mainly comprises a beam (1), a travel cart (2), a soot lance (3), a lift valve (4), a valve opening and closing mechanism (5), an air valve, a negative-pressure wall case (7), a support and suspension mechanism (8), a front carrier (9) and a travel switch. The beam (1) is a case structure, the width of the beam is 545mm+/-2mm, the height of the beam is 370mm+/-2mm or 410mm+/22mm, the soot lance (3) and an inner pipe (3-1) are mounted at the lateral edges of the beam (1), and an axle center of the inner pipe (3-1) is located at a horizontal position of 154mm+/-1mm and a vertical position of 310mm+/-1mm on one side of the beam (1). The elongated retractable soot blower for a negative-pressure boiler has the advantages that the soot blower is reasonable in design, and can meet field installation requirements to the maximum extent by the aid of dimensional design of the beam and a skewing arrangement mode of the soot lance (a lance pipe is mounted at the edge of the beam).
Description
Technical field
The utility model product relates to the used soot blower field of balanced draft boiler.Be specifically related to the long retractable soot blower of a kind of balanced draft boiler.
Background technology
The design that the used soot blower of existing balanced draft boiler has is reasonable inadequately, and it is convenient inadequately to install and use.
The utility model content
The purpose of this utility model is exactly to provide a kind of balanced draft boiler long retractable soot blower at the above-mentioned deficiency of the used ash gun of existing balanced draft boiler.
The utility model mainly is made of beam body, sport car, ash gun, lift valve, valve opening and closing mechanism, air valve, negative pressure wall case, a loop wheel machine structure, front rack and travel switch; The beam body is equipped with tooth bar on the both sides, output gear is meshed with the tooth bar of beam body on the sport car, ash gun links to each other with sport car, lift valve is fixed on Liang Tishang and links to each other with interior pipe, thereby the outlet of valve source of the gas is communicated with ash gun, air valve links to each other with lift valve, valve opening and closing mechanism is installed on the sport car, negative pressure wall case, a loop wheel machine structure, front rack and travel switch are installed in Liang Tishang, beam body front-end and back-end are equipped with limitation travel switch, be provided with the travel switch finger and start soot blower valve striker on sport car; The beam body is a case structure, and its width is 545 mm ± 2mm, height 370 mm ± 2mm or 410mm ± 2mm.Ash gun and interior pipe are installed in the side of beam body, and the interior tubular axis heart is positioned at the horizontal level 154 mm ± 1mm place of beam body one side.Upright position 310 mm ± 1mm place ash gun 3 adopts the varying cross-section duct structure.Can reduce the winding degree of gun barrel under the deadweight effect.
The utility model has the advantages that: the utility model is reasonable in design, and the size design of beam body and ash gun pipe adopt bias mode (gun barrel is installed in limit, beam side) can adapt to on-the-spot installation requirement to greatest extent.The non-uniform beam structure that adopts ash gun can effectively reduce the winding degree that the gun barrel deadweight produces.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is this beam body size and the position view of interior pipe 3-1 in beam body 1.
Accompanying drawing 3 shows structural representation for gun barrel cuts open.
The specific embodiment
As shown in Figure 1; (sport car comprises airtight and watertight padding and the gland between motor, gear-box and ash gun and interior pipe to the utility model by beam body 1, sport car 2.The motor end is a flange arrangement, directly is connected with sport car by after the one-level gear graduation, pays and the gear train transmission mechanism by a worm and wormwheel.Export required rotating speed by the two ends walking gear, realize moving back and forth thereby wheel and rack engagement drives sport car, simultaneously in the sport car bevel gear on the driving shaft rotate and make the ash gun rotation, to be implemented in the reciprocating motion that is rotated simultaneously.), ash gun 3, lift valve 4, valve opening and closing mechanism 5, air valve, negative pressure wall case 7, a loop wheel machine structure 8 (being used for a hanging beam body), front rack 9 (be positioned at the front end-plate below of ash gun beam, be fixed on the front end-plate, approximately supporting half of ash gun weight.Support roller is arranged at carriage bottom, is supporting the ash gun pipe, and gun barrel is entered boiler by the wall case play the guiding role) and the travel switch formation; The beam body is equipped with tooth bar on 1 both sides, on sport car 2 output shafts walking gear is housed, walking gear is meshed with the tooth bar of beam body 1, ash gun 3 links to each other with sport car 2, lift valve 4 mounting rail bodies 1 and link to each other with interior pipe, air valve communicates with lift valve 4, and valve opening and closing mechanism 5 is installed on the sport car 2, negative pressure wall case 7, a loop wheel machine structure 8, front rack 9 and travel switch are installed on the beam body 1, and sport car 2 is provided with travel switch finger 1-1 and starts lift valve striker 1-2; Beam body 1 is a case structure, and its width is 545 mm ± 2mm, height 370 mm ± 2mm or 410mm ± 2mm; The interior pipe 3-1 of ash gun 3 is installed in the side of beam body 1, and interior pipe 3-1 axle center is positioned at the horizontal level 154 mm ± 1mm place of beam body 1 one sides.Upright position 310 mm ± 1mm place (see figure 2).Ash gun 3 is the varying cross-section duct (see figure 3).
Working method
Sport car is installed in orbit during use, and the motor of sport car is connected with the electric control mechanism lead, and purge cycles is in original position from ash gun.Behind the power connection, the motor-driven sport car is sent into ash gun in the stove along the guide rail reach of beam both sides.After nozzle entered in the stove, the sport car Open valve blew the ash beginning.Sport car continues ash gun precession boiler, until after the front end limit, and the sport car counter-rotating, the guiding gun barrel retreats with the grey tracks that blows different when advancing.When nozzle during near furnace wall, valve closing blows ash and stops.Sport car continues to retreat, and gets back to original position.
