Abstract
The utility model relates to a cinder discharger for coal gasifying boiler and belongs to the technical field of machinery. The utility model mainly consists of a cinder discharging part, a driving part and a supporting frame. The cinder discharging function is mainly completed by cinder outlet teeth which have rib wings; the cinder outlet teeth can also loosen the coal bed; the driving part adopts a chain driving method; the supporting frame is made of figured irons; and the whole cinder discharger is a rectangle and can be used in match with the gasifying boiler. The utility model is characterized in that: the utility model has small occupying area and simple structure and makes the gasifying boiler convenient to be cooperated and collocated with other parts of the gasifying boiler.
Description
The utility model relates to a kind of diffusing coal gasification combustion boiler slag extractor.
The coal gasification combustion boiler that looses can improve boiler thermal output, reduces the original discharge concentration of blackness of exhaustion and boiler significantly, belongs to energy saving and environment friendly boiler.Gasification installation is one of capital equipment of this type boiler.The deslagging mode of gasification installation is divided into manual slag tap and machinery is slagged tap.The hand dump grate of the many employings of manual slagging-off is applicable to the small evaporator device that intermittence, coal was slagged tap.For the large-scale gasification fired boiler that needs continous-stable operation, must be continuously on coal and slagging tap continuously.The machinery deslagging device can satisfy this requirement.The existing mechanical deslagging device mostly is disc-shaped structure, complex structure, and can only be used for circular gasification furnace burner hearth.Taking up room of circular gasification hearth is big with floor space, is not easy to combustion parts and heat exchanging part coupling with boiler.
The utility model proposes a kind of diffusing coal gasification combustion boiler slag extractor at the deficiency that prior art exists.
Elaborate the utility model principle and structure below in conjunction with accompanying drawing, the utility model is made of slagging-off part, running part and bracing frame.The slagging-off part is made of power transmission shaft 2, the tooth 3 of slagging tap, be rib wing 7 around each tooth of slagging tap, air enters the coal seam by the gap between the rib wing 7, several slag tap tooth 3 strings on power transmission shaft 2, the length of power transmission shaft 2 and quantity determined by boiler capacity, but with the length of the power transmission shaft 2 of tooth 3 contact portions of slagging tap be the integral multiple of the single tine length of slagging tap, in order to improve heat resisting temperature, the tooth 3 usefulness heat-resisting cast iron of slagging tap are made, and power transmission shaft links together by the bearing block 5 usefulness bolts and the bracing frame 4 at two ends.Running part comprises sprocket wheel 6 and chain 1.Be equipped with two sprocket wheels on each power transmission shaft 2, sprocket wheel 6 is positioned at the end of power transmission shaft 2, adopts the key connected mode.Pair of sprocket corresponding on the adjacent power transmission shaft connects with driving-chain 1, and a sprocket wheel 6 in the outside, end is driven by motor and speed reducer by another driving-chain.Bracing frame 4 is made by shaped steel.Play the support positioning action to each parts, bracing frame 4 links together with the steelframe of boiler.During slag extractor work, the driven by motor reductor also rotates sprocket wheel 6 and each power transmission shaft by driving-chain 1, tooth 3 slow rotation thereupon of slagging tap, the end of the tooth 3 of slagging tap on the adjacent power transmission shaft 2 is along with the rotation of power transmission shaft 2, its distance alternately changes, lime-ash is discharged boiler, when the tooth 3 of slagging tap rotates, also can play the effect in loose coal seam.
The utility model profile is a rectangle, can with the gasification furnace adapted of rectangle, it is little to have floor space, simple in structure, is convenient to the layout that cooperates of gasification furnace and gasification fired boiler other parts.
Fig. 1 is the utility model front view.
Fig. 2 is the utility model side view.
Fig. 3 is the attached view of the utility model.
Embodiment:
The slag extractor of 2t/h gasification fired boiler configuration has 6 power transmission shafts, and shaft length is 1600mm, diameter of axle 80mm, distance between adjacent two axles is 300mm, and string has 20 teeth of slagging tap on the every power transmission shaft, and the sprocket wheel of two diameter 200mm is housed in the end of every axle.
