Abstract
The utility model relates to a driving mechanism for a long stretching soot blower, which has the structure that two big sprocket wheels are driven by a motor through a speed reducer, and a support device is moved by chains which are also driven by the sprocket wheels; a spiral gear pair which is coaxial with a small sprocket wheel is rotated, and therefore, a soot blowing gun is propelled to rotate, and the rotation as well as the movement of the soot blowing gun can be realized. The utility model has the advantages of simple structure, reliability, low cost, etc.
Description
Soot blower is the ashes that the burner hearth, ceiling, the air that are used for removing boiler gives positions such as hot device and back-end ductwork, to guarantee high efficiency boiler, safe operation.Homemade soot blower is because problems such as design and crudy can not satisfy instructions for use.The soot blower major part of present domestic use is Chinese-foreign joint product, and wherein with the most use is Hubei one boiler accessory machinery factory and the U.S. joint " Hubei-Dai Mengde " soot blower, the market in its occupying power more than 80%.But the foreign capitals product also has weak point, with long retractable soot blower is example, its transmission system is very complicated: it drives ash gun by motor by primary pinion-worm and wormwheel-displacement gear-walking gear and tooth bar and moves, and makes the ash gun rotation with a pair of conical gear again.Complicated transmission system must be brought higher cost.
The utility model is at the deficiency of transmission mechanism existence in the existing long retractable soot blower, propose a kind of simple in structure, the transmission mechanism that transmission efficiency is high.
The utility model adopts the chain transmission, and single helical gear is cylindric spiral gear just, and processing technology is uncomplicated, though its engagement belongs to the some contact, bearing capacity is not high, and the ash gun rotational resistance is very little, only needs can satisfy requirement of strength with general material; Helical gear supporting slide adopts rolling bearing, and moving resistance is little, and oval slotted hole is arranged in the slide, can realize the backhaul space, makes the injection track stagger uniform.The purpose of this utility model is to realize like this, motor 1 drives two hinge wheels 3 by decelerator 2, drive chain 4, chain 4 drives supporting slide 8, ash gun 7 is moved, and chain 4 rotates minor sprocket 5 simultaneously, makes helical tooth wheel set 6 rotations coaxial with minor sprocket, rotate thereby order about ash gun, realize that ash gun not only moves but also rotate.Nozzle 9 is installed in the front end of ash gun 7.Supporting has oval slotted hole in the slide 8, when ash gun just begins backhaul, this slotted hole can make ash gun wouldn't travelling backwards (very short stroke) and rotate, thereby make as usual when blowing grey track with reach blow grey track stagger, uniform.
The utlity model has simple in structure, reliable, cheap advantage, tangible economic benefit and social benefit are arranged, the stronger market competitiveness is arranged.
Fig. 1 is the utility model principle assumption diagram
Fig. 2 is the utility model Fig. 1 vertical view
Embodiment: three phase alternating current motor, power are relevant with ash gun length, and 0.37 kilowatt～1.1 kilowatts, chain is a standard component, and the supporting slide adopts to roll and supports, and the ash gun rear end is supported by the supporting slide.
