The specific embodiment
Embodiment: shown in Fig. 1-7, layering that a kind of chain grate boiler is unpowered branch coal feeder comprises layering grid 2 and branch's baffle plate 7 and fixing, guiding mechanism, and said layering grid 2 is divided into Mi Ganqu from high to low, dredges the bar district and does not have the bar district; Said branch baffle plate 7 be arranged on layering grid 2 Mi Ganqu under, unpowered formation layering branch; Said layering grid 2 for low early and high afterly be obliquely installed, high back low dip settings before branch's baffle plate 7, and the whole guiding mechanism of tilt adjustable is set respectively; Between the fire grate front end that said layering grid 2 and branch's baffle plate 7 are arranged on boiler and the coal bunker outlet (1 is coal moving roller among Fig. 1, and 4 is coal bunker coal flashboard), and the adjustable fixed mechanism of setting height(from bottom) is set respectively.
The grid bar of layering grid 2 is that round steel is made, and grid bar end is length and is provided with at interval, and promptly layering grid 2 is provided with by oval steel 13 and short round steel 12 at interval, and short round steel 12 ends vertically are provided with lower, transverse reinforcement 11.Branch's baffle plate 7 is the high ebb setting of W type, and is provided with baffle plate bottom reinforcement 16; Branch's baffle plate 7 is by steel plate compression moulding, and from left to right, per two peaks district offers V font discharging area from high to low, and v-shaped openings is downward, connects and composes a W type branch baffle plate between per three peaks.
Coal bunker outlet supported on both sides steel plate is provided with the fixed installation height that is respectively applied for adjustment layering grid, branch's baffle plate and layering grid locking device, layering grid guiding mechanism, branch's baffle plate locking device and branch's baffle plate guiding mechanism at angle of inclination.
The body steel pipe of layering grid 2, branch's baffle plate 7 all becomes vertical angle with the axis of the end steel pipe of self locking device, guiding mechanism respectively in same plane.
The guiding mechanism 3,8 of the angular adjustment of layering grid 2, branch's baffle plate 7 constitutes by L shaped swing bracing frame 21, fixed screw 22, lock nut 23 and the coal bunker outlet supported on both sides steel plate 18 of separately body steel pipe 10,14, the vertical steel pipe in end (being angular adjustment bar 9,15), the oval chute of belt length; The vertical steel pipe in end (being angular adjustment bar 9,15) of the angle-adjusting mechanism of said layering grid 2, branch's baffle plate 7 is in plumbness with self L shaped swing bracing frame 21.
The layering grid 2 of layering branch coal feeder and branch baffle plate 7 overall co-ordinations are installed effect and are and are similar to " people " font; Do not increase external impetus, rely on coal-fired falling gravity, accomplish layering and branch in the dropping process between coal bunker outlet and traveling-grate stoker.Described layering grid is provided with sealing plate with the height adjusting of branch's baffle plate with oval elongated slot place; Spacing between per two grid bars of described layering grid, between per two peaks of branch's baffle plate all can be according to the coal-fired granularity in the use, layering branch effect, and adjustment is provided with when making.
Because the utility model has been taked technique scheme, raw coal is dialled in coal bunker under the effect of coal rod, relies on self gravitation, falls the layering grid through following coal mouth.Because layering grid 2 tilts, maximum coal cinder glides along layering grid 2, until fall on the fire grate foremost formation ground floor 24, i.e. rough coal layer through no bar district; This moment, traveling-grate stoker was moved in burner hearth by front end, and bigger coal cinder glides along layering grid 2, falls in the thin bar district of layering grid 2, falls above the rough coal layer that falls earlier, forms the second layer 25, promptly middle coal seam; Traveling-grate stoker is continued in burner hearth, to move by front end, and broken coal falls at layering Mi Ganqu, fall coal seam in falling earlier above, form the 3rd layer 26, i.e. the duff layer.Like this, the thick coal cinder that layering grid 2 sieves out drops on the bottom of fire grate, and bigger coal cinder drops in the middle of the coal seam, and broken coal drops on the coal seam topmost, forms by ground floor rough coal layer coal seam in the second layer and accomplishes coal-fired layering in early stage again to the 3rd layer of duff layer.Simultaneously, the 3rd layer of duff layer is in the process of accomplishing layering, and shunting, the confluxing effect of branch's baffle plate 7 of installing through layering grid 2 bottoms again cover in the second layer on the coal seam the final branch after the layering of completion duff layer.
Simultaneously; According to different coal properties and control requirement,, can change the shape and the effect of layering, branch respectively through the setting height(from bottom) and the angle of inclination of adjustment layering grid, branch's baffle plate; Reach and reduce air blast resistance, the abundant raw coal that burns, improve the effect of radiation heat transfer, heat convection.
