The specific embodiment
Embodiment: as shown in Fig. 1-7, a kind of chain grate boiler is unpowered layering rowed coal feeder, comprises layering grid 2 and branch's baffle plate 7 and fixing, guiding mechanism, and described layering grid 2 is divided into Mi Ganqu, He Wugan district of Shu Gan district from high to low; Described branch baffle plate 7 be arranged on layering grid 2 Mi Ganqu under, unpowered formation layering branch; Described layering grid 2 low dip setting for being low early and high afterly obliquely installed, after the front height of branch's baffle plate 7, and the adjustable guiding mechanism in angle of inclination is set respectively; Between the fire grate front end that described layering grid 2 and branch's baffle plate 7 are arranged on boiler and coal bunker outlet (in Fig. 1,1 is coal moving roller, 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 interval and arranges, and layering grid 2 is arranged by oval steel 13 and short round steel 12 intervals, and short round steel 12 ends are vertically 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 compressing by steel plate, and from left to right, Mei Liangge peak 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 every three peaks.
Coal bunker outlet supported on both sides steel plate is provided with and is respectively used to adjust the fixed installation height of layering grid, branch's baffle plate and the layering grid locking device at angle of inclination, layering grid guiding mechanism, branch's baffle plate locking device and branch's baffle plate guiding mechanism.
The body steel pipe of layering grid 2, branch's baffle plate 7 respectively with all degree in a vertical angle in same plane of axis of the end steel pipe of self locking device, guiding mechanism.
The guiding mechanism 3,8 of the angular adjustment of layering grid 2, branch's baffle plate 7 forms by body steel pipe 10,14 separately, end vertical steel tube (being angular adjustment bar 9,15), L shaped swinging supporter 21, fixed screw 22, lock nut 23 and coal bunker outlet supported on both sides steel plate 18 with oblong chute; The end vertical steel tube (being angular adjustment bar 9,15) of the angle-adjusting mechanism of described layering grid 2, branch's baffle plate 7 and self L shaped swinging supporter 21 are in plumbness.
The layering grid 2 of layering rowed coal feeder and branch baffle plate 7 overall co-ordinations are installed effects and are and are similar to " people " font; Do not increase external impetus, rely on coal-fired fall gravity, in the dropping process between coal bunker outlet and traveling-grate stoker, complete layering and branch.Described layering grid arranges sealing plate with the height adjusting of branch's baffle plate with oval elongated slot place; Between every two grid bars of described layering grid, every two high peak-to-peak spacing of branch's baffle plate, all can, according to the coal-fired granularity in use procedure, layering branch effect, in the time making, adjust and arrange.
Because the present invention has taked technique scheme, raw coal is dialled under the effect of coal rod in coal bunker, relies on self gravitation, falls layering grid by lower coal mouth.Because layering grid 2 tilts, maximum coal cinder glides along layering grid 2, until fall on fire grate foremost by Wu Gan district, forms ground floor 24, i.e. rough coal layer; Now traveling-grate stoker is by front end to stove chamber inner movement, and larger coal cinder glides along layering grid 2, and at layering grid, 2 Shu Gan districts fall, and falls above the rough coal layer first falling, and forms the second layer 25, i.e. middle coal seam; Traveling-grate stoker is continued to stove chamber inner movement by front end, and broken coal falls at layering Mi Ganqu, fall first fall middle coal seam above, form the 3rd layer 26, i.e. duff layer.Like this, the thick coal cinder that layering grid 2 sieves out drops on the bottom of fire grate, and larger coal cinder drops in the middle of coal seam, and broken coal drops on coal seam topmost, forms by ground floor rough coal layer to coal seam in the second layer again to the 3rd layer of duff layer, completes coal-fired layering in early stage.Meanwhile, the 3rd layer of duff layer is in the process that completes layering, then shunting, the effect of confluxing of branch's baffle plate 7 of installing through layering grid 2 bottoms, covers in the second layer on coal seam, completes the final branch after the layering of duff layer.
Simultaneously, according to different coal properties and control requirement, by adjusting setting height(from bottom) and the angle of inclination of layering grid, branch's baffle plate, can change respectively shape and the effect of layering, branch, reach and reduce air blast resistance, the abundant raw coal that burns, improve the effect of radiation heat transfer, heat convection.
