Abstract
The utility model relates to a connection structure of a long retractable soot blower carriage and an external soot blowing tube, which is used for removing ash and slag on the surface of a heating furnace in a petrochemical industry, power industry and the like. The connection structure comprises a carriage (1) and the external soot blowing tube (2), wherein the carriage (1) comprises a motor (101) and a double-output shaft reducer (102); the double-output shaft reducer (102) is provided with one input shaft and two output shafts; one output shaft is provided with a main transmission disk (103) and a reducer sprocket (104); a semicircular groove (107) is formed on the main transmission disk (103); a pin (106) is embedded in the groove (107) and fixedly connected with the reducer sprocket (104); and a soot blowing tube sprocket (201) is arranged on the outer edge of the external soot blowing tube (2) and connected with the reducer sprocket (104) through a chain. Through the connection structure, blowing dead angle does not exist on the external soot blowing tube.
Description
(1) technical field
The utility model 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 utility model was made, the flexible soot blower of length in the past has the following disadvantages: the sprocket wheel on two shaft reductors was identical with the sprocket wheel lead of helix of blowing outward on the blowing pipe, therefore had the purging dead angle, to boiler tube to blow ash unclean.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of outer blowing pipe that blows not have flexible soot blower sport car of the length that purges the dead angle and the syndeton of blowing blowing pipe outward.
The purpose of this utility model is achieved in that flexible soot blower sport car of a kind of length and the syndeton of blowing blowing pipe outward, comprise a sport car and an outer blowing pipe that blows, described sport car includes a motor and a pair of shaft reductor, described pair of shaft reductor has a power shaft and two output shafts, one main transmission dish and one speed reducer sprocket wheel wherein are installed on the 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; Blow the blowing pipe outer rim and be provided with a blowing pipe sprocket wheel outside described, this blowing pipe sprocket wheel links to each other with described decelerator sprocket wheel by a chain.
The purging angle of this soot blower is 360 °, purges stroke range 2.5～6m.
The beneficial effects of the utility model are:
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.
(4) description of drawings
Fig. 1 is long flexible soot blower sport car of the utility model and the Facad structure schematic diagram that blows the syndeton of blowing pipe outward.
Fig. 2 connects main transmission dish and sprocket wheel schematic diagram on the sport car decelerator of the present utility model.
Fig. 3 is the A-A cut-away view of Fig. 2.
Reference numeral among the figure:
Blow blowing pipe 2, blowing pipe sprocket wheel 201 outward;
(5) specific embodiment
Referring to Fig. 1～3, Fig. 1 is long flexible soot blower sport car of the utility model and the Facad structure schematic diagram that blows the syndeton of blowing pipe outward.Fig. 2 connects main transmission dish and sprocket wheel schematic diagram on the sport car decelerator of the present utility model.Fig. 3 is the A-A cut-away view of Fig. 2.By Fig. 1, Fig. 2 and Fig. 3 as can be seen, long flexible soot blower sport car of the utility model and the syndeton of blowing blowing pipe outward, comprise a sport car 1 and an outer blowing pipe 2 that blows, described sport car 1 includes a motor 101 and a pair of shaft reductor 102, described pair of shaft reductor 102 has a power shaft and two output shafts, one main transmission dish 103 and one speed reducer sprocket wheel 104 wherein are installed on the output shaft, offer the groove 107 of a semi-round ring shape on the main transmission dish 103, be equipped with a pin 106 in the groove 107, pin 106 is fixedlyed connected with described decelerator sprocket wheel 104; Blow blowing pipe 2 outer rims and be provided with a blowing pipe sprocket wheel 201 outside described, this blowing pipe sprocket wheel 201 links to each other with described decelerator sprocket wheel 104 by a chain.
Claims (1)
1. one kind long flexible soot blower sport car and the syndeton of blowing blowing pipe outward, comprise a sport car (1) and an outer blowing pipe (2) that blows, it is characterized in that: described sport car (1) includes a motor (101) and a pair of shaft reductor (102), described pair of shaft reductor (102) has a power shaft and two output shafts, one main transmission dish (103) and one speed reducer sprocket wheel (104) wherein are installed on the output shaft, offer the groove (107) of a semi-round ring shape on the main transmission dish (103), be equipped with a pin (106) in the groove (107), pin (106) is fixedlyed connected with described decelerator sprocket wheel (104); Blow blowing pipe (2) outer rim and be provided with a blowing pipe sprocket wheel (201) outside described, this blowing pipe sprocket wheel (201) links to each other with described decelerator sprocket wheel (104) by a chain.
