In the invention, the outer soot blowing pipe has no blowing dead angles; the pressure of fillers in a filler box is stable; the matching in the steam inlet valve is precise; and the pressure of a steam outlet can be regulated.
Description
(1) technical field
The present invention relates to a kind of soot blower.Be used for surfaces such as convection bank on the heating furnace, the heating furnace in the power industry, boiler of petrochemical industry, air preheater, economizer superheater and carry out ash disposal, slagging-off.Belong to petrochemical industry, electrical equipment technical field.
(2) background technology
Convection bank on heating furnace in petrochemical industry, the heating furnace in the power industry, the boiler, air preheater, economizer superheater etc., generally all adopt soot blower that ash disposal, slagging-off are carried out in its surface, reduce exhaust gas temperature, to improve the thermal efficiency of heating furnace, boiler, reach the purpose of energy-conservation of consumption reduction.When cigarette temperature in the stove surpasses 550 ℃, should adopt long flexible soot blower.This soot blower rotates reciprocal stretching motion as straight line in burner hearth when blowing ash.When not blowing ash, blow blowing pipe outward in burner hearth outside, can avoid outer when blowing blowing pipe the cigarette temperature is greater than 550 ℃ in stove and the bending that causes like this, there was a mechanical failure thereby cause soot blower.Before the present invention made, the flexible soot blower of length in the past had the following disadvantages:
1, the sprocket wheel on two shaft reductors is identical with the sprocket wheel lead of helix of blowing outward on the blowing pipe, therefore exist to purge the dead angle, to boiler tube to blow ash unclean.
2, the gland of stuffing box is subjected to equipment operation to the pressure of filler and changes.Movement locus when outer blowpipe blows ash simultaneously is rectilinear motion and gyration, influences the service life of filler.Cause steam leakage.
3, flap in the air intake valve and valve rod adopt global design, and flap, flap form rigidity with valve seat and contact, when valve rod upwards promotes flap cooperate with valve seat inaccurate, easy generation leakage.
4, the pressure of steam (vapor) outlet is non-adjustable in the air intake valve.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of outer blow blowing pipe do not exist pressure stability, the air intake valve of the filler that purges dead angle, stuffing box inner cooperate accurate, the length that steam exit pressure the is adjustable soot blower that stretches.
The object of the present invention is achieved like this: a kind of length soot blower that stretches, comprise a casing, the casing upper level is furnished with a guide rail, be furnished with a sport car on the guide rail, sport car includes a motor and a pair of shaft reductor, described pair of shaft reductor has a power shaft and two output shafts, an output shaft links to each other with described guide rail by a rack-and-pinion, one main transmission dish and one speed reducer sprocket wheel are installed on another output shaft, the main transmission dish is connected by key with described another output shaft, offer the groove of a semi-round ring shape on the main transmission dish, be equipped with a pin in the groove, pin is fixedlyed connected with described decelerator sprocket wheel; In described casing horizontally disposed have blow blowing pipe outside one, this outer blowing pipe that blows places described guide rail below, this is outer to blow the blowing pipe outer rim and is provided with a blowing pipe sprocket wheel, this blowing pipe sprocket wheel links to each other with described decelerator sprocket wheel by a chain; A described outer end that blows blowpipe in blowing pipe one end and is rotationally connected, the other end of interior blowpipe links to each other with the gas outlet of an admission valve, and the valve rod of this admission valve links to each other with an operating mechanism, this operating mechanism is provided with a shift fork, corresponding to this shift fork, described sport car top is provided with a striker with matching, also is provided with a collision block on described sport car top simultaneously, corresponding to this collision block, be provided with a travel switch with matching at described casing front and rear.
The long flexible soot blower of the present invention, a described outer end that blows blowing pipe is rotationally connected by the outer rim of a bearing and a gland and a stuffing box, the endoporus of this stuffing box links to each other with an end of blowpipe in, and in described, set packing seal between the endoporus hole wall of the outer rim of blowpipe and stuffing box, be provided with a gland in described filler outer end, this gland is fixedlyed connected with the end face of described stuffing box with one group of locking butterfly spring by bolt.
The long flexible soot blower of the present invention, described admission valve comprises valve seat, flap, valve rod, pressure adjustment disk and lock nut, the flap upper surface is provided with an inverted T-slot, corresponding to this T-slot, the T shape head of cooperation is arranged to patch with it in described valve rod lower end, and described pressure adjustment disk and lock nut are arranged on the valve rod upper end.
The purging angle of soot blower of the present invention is 360 °, purges stroke range 2.5～6m.
The invention has the beneficial effects as follows:
1, the two shaft reductors on the soot blower sport car have carried out new design, the gear-box of this pair shaft reductor is two output shafts of motor input and axle (promptly an output shaft drives outer blowpipe for rotatablely moving, and another output shaft drives the stuffing box moving linearly).When the distance sport car was gone to default stroke and drawn back, the reductor sprocket wheel on two shaft reductors was taken inventory relatively rotating at relative half-turn with main transmission.The outer purging track that blows blowing pipe advanced just in time deposit staggering of 1/2 lead of helix with retreating, make purge avoided the dead angle, to boiler tube to blow ash cleaner.
2, the packing ring on gland adopts one group of dish spring, can keep gland that the pressure of filler is not subjected to equipment operation and changes.Effectively blow blowing pipe vibrations at the volley outside the buffering simultaneously, reduce the radial pressure that filler is produced, alleviate the compression-extent of rebound of filler, prolong the service life of filler.
3, the flap in the air intake valve adopts with valve rod and separates design, makes flap, flap form flexible the contact with valve seat, guarantees flap and valve seat precision-fit when valve rod upwards promotes, and has prevented leakage.
4, be provided with the pressure adjustment disk in the air intake valve, adjustment disk is made the pressure of the steam (vapor) outlet regulated of commentaries on classics up and down, make the purging pressure of the soot blower of operating position can satisfy the purging requirement, after pressure was regulated and finished, available lock nut locked the pressure adjustment disk.
