Abstract
The utility model discloses an adjustable swirler for flame shapes of a rotary kiln burner, which can realize online rotating direction adjustment of rotary wind, and lead the angle of a rotary air flue to be flexibly adjusted so as to adapt to different flame demands. The adjustable swirler for the flame shapes of the rotary kiln burner simplifies a mechanism, is easy to manufacture and maintain, and also reduces energy loss brought by air resistance, and is beneficial for environmental protection. The adjustable swirler for the flame shapes of the rotary kiln burner consists of a rotary blade, a fixed rotating shaft, a movable rotating shaft, a rotary inner air pipe, and a rotary outer air pipe. The rotary inner air pipe is coaxially arranged in the rotary outer air pipe; the rotary blade is arranged between the rotary inner air pipe and the rotary outer air pipe; one end of the rotary blade is provided with a round hole in advance; the fixed rotating shaft is arranged in the round hole; the fixed rotating shaft is arranged at the outer wall of the rotary inner air pipe; the other end of the rotary blade is provided with a long hole in advance; the movable rotating shaft is arranged in the long hole, and is arranged at the inner wall of the rotary outer air pipe. The adjustable swirler for the flame shapes of the rotary kiln burner has simple structure and is convenient to replace; moreover, the maintenance cost is obviously reduced; the energy loss is reduced; and more energy is saved; in addition, the emission is reduced; and the environment is protected.
Description
Technical field
The utility model relates to rotary kiln burner, especially a kind of adjustable swirl-flow devices of rotary kiln burner flame profile.
Background technology
Traditional rotary kiln multicenter combustor generally is made up of eddy flow wind passage, axial flow wind passage and coal wind duct etc., be provided with cyclone in the eddy flow wind passage, cyclone is one and the angled spiral groove channel of axis, this helicla flute is changeless after burner is made finished product, can't adjust as required.In fact, owing to the difference of fuel and the variation of fuel value height, guarantee that burner flame can be in best fired state, makes corresponding angle adjustment with regard to the cyclone that requires to control eddy flow wind direction in the burner use.The adjustable cyclone of the up-to-date development of Austrian Unitherm company, its structure are that the nozzle direction is carried out small adjustment to reach the change of eddy flow wind direction by pipeline that is hidden in the exogenous wind channel interior and nozzle ejection eddy flow wind.This structure by nozzle, connect flexible pipe, adjust air grid and the rear portion guiding mechanism is formed, and these mechanisms all are in the exogenous wind channel interior, high velocity air will certainly produce certain influence to it.
In view of the foregoing, the rotary kiln multicenter combustor needs to improve.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art; a kind of adjustable swirl-flow devices of rotary kiln burner flame profile is provided; the rotation direction that can realize rotating wind is online adjustable; make the adjustment of rotation air channel angle flexible; adapt to different combustion flame needs, simplified mechanism, be easy to make and safeguard; reduce the energy loss that windage is brought simultaneously, helped environmental protection.
The utility model adopts following technical scheme to achieve these goals: a kind of adjustable swirl-flow devices of rotary kiln burner flame profile is by moving blade, fixed rotating shaft, and mobile shaft, pipe in the rotation wind, rotation wind outer tube constitutes; The coaxial setting in the rotation wind managed in the rotation wind outer tube; Between pipe and the rotation wind outer tube moving blade is set in the rotation wind, an end of moving blade is reserved circular hole, and fixed rotating shaft is set in the circular hole, and fixed rotating shaft is arranged on the pipe outer wall of pipe in the rotation wind; The other end of moving blade is reserved slotted hole, and mobile shaft is set in the slotted hole, and mobile shaft is arranged on the inside pipe wall of rotation wind outer tube.
Pipe can move mutually with rotation wind outer tube in the rotation wind, drives mobile shaft and moves in the slotted hole of moving blade, makes moving blade center on fixed rotating shaft and rotates.
Operation principle of the present utility model is: when the rotation wind passage inner and outer pipes of burner takes place axially mutual when mobile, rotation wind outer tube drives the shifting axle associated movement, shifting axle slides in the slotted hole of moving blade, driving moving blade rotates around fixed axis, thereby the angle of having realized moving blade and conduit axis changes, high velocity air flows with the conduit axis direction, thereby has changed airflow direction, makes the airflow direction of burner ejection change.
The beneficial effects of the utility model are: structure of the present utility model has realized any adjustment of rotation wind direction in the certain angle; Structure of the present utility model is dismountable, simple in structure, is convenient to change; Moving blade of the present utility model is a consumable accessory, and only need are changed moving blade and do not needed to change whole head pipeline, and maintenance cost significantly reduces; Reduce pipeline and guiding mechanism in the outer air channel, thereby reduced windage, the loss that cuts down the consumption of energy, more energy-conservation; Reduce discharging, protected environment.
Description of drawings
