Abstract
The utility model relates to a bottom of coal gas generator with external rotary bearing gear, belonging to the fitting device of coal gas generator, which comprises a bottom shell and a rotary ash disk adaptive with the top of the bottom shell. The utility model is characterized in that the rotary ash disk via a hollow shaft is coaxially connected with a large gear outside the furnace, the side of the hollow shaft is provided with air holes, a blast box is arranged relative to the air holes, the large gear and the blast box fixed on the bottom shell are provided with a rotary bearing therebetween, the rotary bearing is composed of engaged an inner ring and an outer ring, the blast box is fixedly connected with the inner ring, and the large gear is fixedly connected with the outer ring. The utility model arranges large gear outside furnace, to be away from high temperature and avoid heat hurt to prolong the service life of the large gear to make installment, debug and maintenance simple. And the utility model uses rotary bearing as transmission, while the inner and outer rings are positioned oppositely to avoid displacement of the ash disk, thereby realizing stable transmission and avoid tooth broken on the large gear, to confirm normal production. The service life of the bottom assembly is longer than 3 years.
Description
Technical field
The utility model relates to a kind of improved producer gas generator furnace bottom, belongs to the accessory facility of producer gas generator.
Technical background
The producer gas generator furnace bottom comprises bearth shell and rotates ash-pan, rotates ash-pan and bearth shell top and adapts, and in process of production, is fixed on fire grate on the ash-pan and follows ash-pan and rotate together.Existing producer gas generator furnace bottom is made up of bearth shell, ash-pan, up and down slideway, steel ball and master wheel, and up and down slideway is separately fixed on ash-pan and the bearth shell, and steel ball places between the up and down slideway, is driven by master wheel, and up and down slideway relatively rotates.Because the ash bed temperature on the fire grate is higher above the ash-pan, cause the ash-pan bottom steel ball slideway serious wear of being heated, in addition, owing to do not have fine locator means between ash-pan and the bearth shell, occur displacement easily, cause friction resistance to increase, the furnace bottom load increases the weight of, phenomenons such as Tooth Breaking for Bull Gear also can occur, have a strong impact on ordinary production.
The utility model content
The purpose of this utility model is to provide a kind of improved rotating bearing gear external producer gas generator furnace bottom, has avoided being subjected to thermal wear, has prevented the ash-pan displacement, and stable drive has been avoided the Tooth Breaking for Bull Gear phenomenon, has guaranteed ordinary production.
The producer gas generator furnace bottom that rotating bearing gear described in the utility model is external, comprise bearth shell and rotate ash-pan, rotating ash-pan and bearth shell top adapts, its rotate ash-pan by quill shaft with below place stove coaxial connection of master wheel outward, the quill shaft side is provided with the wind hole, the corresponding bellows that is provided with the wind hole, master wheel and be fixed between bellows on the bearth shell and be provided with rotating bearing, rotating bearing is made of inner ring that cooperatively interacts and outer ring, bellows is fixedlyed connected with inner ring, and master wheel is fixedlyed connected with the outer ring.
In order to realize transmission, bearth shell is fixedlyed connected with the outer ring by bellows, and master wheel is fixedlyed connected with inner ring, and situation also is the same.
Master wheel places outside the stove, has broken away from hot environment, has avoided being subjected to thermal wear, has also made things convenient for installation, debugging and maintenance, and by the rotating bearing transmission, has stopped the ash-pan displacement, and stable drive has been avoided the Tooth Breaking for Bull Gear phenomenon, has guaranteed ordinary production.
Between bellows and quill shaft, establish tightness system, prevent to leak, guarantee safety, ordinary production.
Can establish oil circulation and cooling water circulating device according to routine techniques between bellows bottom and quill shaft and on the rotating bearing, can reduce friction resistance, be used to reduce envrionment temperature, guarantee the stable continuous firing of working part.
At the outer ring of rotating bearing outer setting shield cap, avoid lime-ash to enter, influence is rotated.
The producer gas generator furnace bottom that the utility model rotating bearing gear is external, master wheel move to outward outside the stove, break away from hot environment, avoid being subjected to thermal wear, prolonged the work-ing life of master wheel, also made things convenient for installation, debugging and maintenance, and adopt the rotating bearing transmission, inner ring and outer ring relative positioning have been stopped the ash-pan displacement, stable drive, avoided the Tooth Breaking for Bull Gear phenomenon, guaranteed ordinary production, this furnace bottom assembly can extend to more than 3 years work-ing life, can obtain great economic benefit.
Description of drawings
Fig. 1 is an example structure synoptic diagram of the present utility model.
Among the figure: 1, bearth shell 2, rotation ash-pan 3, blast inlet 4, master wheel 5, rotating bearing 6, bellows 7, sealing-ring 8, quill shaft 9, shield cap.
Embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
As shown in the figure, the producer gas generator furnace bottom that rotating bearing gear described in the utility model is external, comprise bearth shell 1 and rotate ash-pan 2, rotate ash-pan 2 by quill shaft 8 with below place stove 4 coaxial connections of master wheel outward, quill shaft 8 sides are provided with the wind hole, the corresponding bellows 6 that is provided with the wind hole, bellows 6 is fixed on the bearth shell 1,8 of bellows 6 and quill shafts are provided with sealing- ring 7,6 of master wheel 4 and bellowss are provided with rotating bearing, rotating bearing is made of inner ring that cooperatively interacts and outer ring, bellows 6 is fixedlyed connected with inner ring, master wheel 4 is fixedlyed connected with the outer ring, and outer ring outer setting shield cap 9 can be established oil circulation and cooling water circulating device on 8 of bellows 6 bottoms and quill shafts and the rotating bearing 5.
In the utility model, bellows 6 is fixedlyed connected with the outer ring, and master wheel 4 is fixedlyed connected with inner ring, and the transmission situation is the same.
Working process:
By driving external master wheel 4, master wheel 4 rotations drive outer ring, the quill shaft 8 of fixedly connected with it rotating bearing 5 and rotate ash-pan 2 and rotate, and realize rotating the rotation of ash-pan 2, and the outer ring of rotating bearing 5 and inner ring are done and relatively rotated.
Air enters bellows 6 from blast inlet 3, and then enters quill shaft 8 by the wind hole, and air-supply in the middle of realizing arrives the producer gas generator bottom, supplies with burning.
