Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of grate structure of coal cinder burner, comprise a combustion gasification body of heater 1, bocca 12 and fire door 13 are set on the sidewall of this combustion gasification body of heater, coal-fired input after combustion gasification body of heater, the gas flame that high temperature is burnt, gasifies and formed to process sprays from bocca, to be the heating such as follow-up corresponding equipment for Heating Processing, kiln.
The utility model arranges a water tank 5 being communicated with combustion gasification body of heater in the bottom of combustion gasification body of heater, a side of water tank arranges a slag notch 51 upward.Like this, the water coolant in water tank, by the bottom sealing of combustion gasification body of heater, avoids the high-temperature flue gas in burner hearth to leak by slag notch.In addition, at combustion gasification body of heater and water tank junction, fire grate 6 is set to support fire coal, water tank can be used as sludge-store cabin chamber for storing remaining cinder after coal cinder combustion gasification.In order to realize not blowing out, remove cinder, fire grate comprises some fire grate major axis 61 of flatly equidistantly arranging, on two sidewalls of water tank, corresponding bearing support is set, the two ends of fire grate major axis are rotatably connected on bearing support, some disintegrating slag tooth groups 62 are set on fire grate major axis vertically equally spacedly, this disintegrating slag tooth group consists of the ratch 621 of even number, and ratch radially extends along fire grate major axis, and is uniformly distributed on fire grate major axis periphery.The ratch quantity of disintegrating slag tooth group preferably can be 4, thereby makes disintegrating slag tooth group be cruciform.The arrangement position of the ratch in every group of disintegrating slag tooth group is identical with angle, thereby on fire grate major axis, forms the ratch of the even column of equidistantly arranging vertically.
In addition, as shown in Figure 3, we can arrange the disintegrating slag tooth group on whole fire grate major axis by unified angle, and a wherein row ratch is the level of state, because the ratch of every group of disintegrating slag tooth group by even number forms, thereby make each rooted tooth bar in disintegrating slag tooth group all there is one oppositely to extend with it and coaxial ratch, that is to say, at the opposite side of fire grate major axis, must form the ratch of a row level simultaneously.Like this, we can guarantee that the both sides of fire grate major axis have respectively the ratch of a row level, and the horizontal ratch on adjacent fire grate major axis is mutually close.By two groups of distances between disintegrating slag tooth group are reasonably set, can make between horizontal ratch, to there is less gap, thereby can effectively support fire coal.When needs are removed cinder, we only need to rotate fire grate major axis, and now the ratch on fire grate major axis can stir, shear and broken cinder, are broken into compared with the cinder of fine grained chippings and can the gap between ratch, drop in the water tank of below.Particularly, when fire grate major axis rotates, its originally the ratch of level progressively tilt, thereby and the distance between the horizontal ratch on adjacent fire grate major axis progressively become greatly, broken cinder can promptly be fallen from the gap between the ratch of adjacent two fire grate major axis.When being deposited on the cinder of water tank bottom, arrive when a certain amount of, can cinder be cleaned out from the slag notch of water tank one side.Because cinder has higher heat, therefore, cinder can make water coolant vaporization rise when falling into the water coolant of water tank, entering into the vaporized chemical that superheated vapor in combustion gasification body of heater can be used as coal cinder uses, thereby avoid the waste of the heat energy that cinder has, and then can improve significantly coal-fired utilization efficiency of heat energy.Certainly, be understandable that, we need to arrange corresponding water monitor in water tank, to guarantee that the water level in water tank remains on rational level.
Certainly, as shown in Figure 4, we also can arrange the disintegrating slag tooth group on the fire grate major axis of odd number root by unified angle, disintegrating slag tooth group on the fire grate major axis of even number root is arranged according to a unified angle simultaneously, and the row ratch on the fire grate major axis of odd number root is the level of state, correspondingly, the opposite side of the fire grate major axis of odd number root must form the ratch of a row level simultaneously, disintegrating slag tooth group on the fire grate major axis of adjacent even number root is arranged according to another unified angle, thereby form a deflection angle between the disintegrating slag tooth group on the fire grate major axis of even number root and the fire grate major axis of odd number root, this deflection angle should equal 180 degree divided by the ratch number in every group of disintegrating slag tooth group, for example, when ratch number is 4, deflection angle is 45 degree, like this, in the disintegrating slag tooth group of the fire grate major axis of odd number root, two relative ratch are flatly arranged in the both sides of fire grate major axis, another two rooted tooth bars are arranged in the both sides up and down of fire grate major axis vertically, wherein the ratch of downside is immersed in the water coolant of water tank, and in the disintegrating slag tooth group of the fire grate major axis of adjacent even number root, two rooted tooth bars are positioned at the below of fire grate major axis, and be symmetrically located at the both sides of fire grate major axis, another two tops that are positioned at fire grate major axis, and being symmetrically located at the both sides of fire grate major axis, two rooted tooth bars of downside are immersed in the water coolant of water tank.In addition, between disintegrating slag tooth group on disintegrating slag tooth group on the fire grate major axis of odd number root and the fire grate major axis of even number root, plugging each other forms dislocation and is spaced, and between the end of horizontal ratch and the outside surface of the fire grate major axis of adjacent even number root, leaves gap on the fire grate major axis of odd number root.Like this, when starting to rotate, the ratch of level forms a downward-sloping oblique angle, on adjacent fire grate major axis, being positioned at fire grate major axis top also synchronously rotates with a horizontal teeth rod rooted tooth bar in angle of 45 degrees, on the one hand can shearing-crushing cinder, can push the cinder on the ratch that pushes script level downwards, downward-sloping ratch is slipped in water tank along side to make cinder simultaneously.
In addition, the water coolant in water tank also can play the effect of cooling fire grate, to extend the work-ing life of fire grate.For this reason, water coolant water level in water tank should remain on fire grate major axis position slightly on the lower side, thereby make ratch downward on fire grate major axis be immersed in the water coolant underwater of water tank, heat on fire grate can promptly pass to the water coolant in water tank by ratch downward on fire grate major axis, being conducive to fire grate maintains a lower temperature on the one hand, meanwhile, the heat of fire grate is conducive to the vaporization of water coolant in water tank, and then can promote to fire coal gasification.
For the convenient cinder of removing, fire grate major axis can be associated with a drive unit (not shown), for example, directly with motor, drives fire grate major axis, makes each fire grate major axis can independent rotation, to alleviate operator's working strength.Or, also can on fire grate major axis stretches out the outer end of water tank, transmitting gear be set, and intermeshing between the transmitting gear on adjacent two fire grate major axis.Like this, when a fire grate major axis rotates, can drive all fire grate major axis to rotate by intermeshing transmitting gear simultaneously, thereby can promptly remove cinder, increase work efficiency.Certainly, now we can go to drive a fire grate major axis wherein by a motor or other power set, or also can drive by manual mode fire grate major axis to rotate.Simultaneously, for fire grate major axis can accurately be located, the end that we can stretch out water tank at wherein fire grate major axis of fire grate arranges turbine, correspondingly, the worm screw meshing with turbine is set rotationally on the outer side wall of water tank, and a rotation handwheel is set in the end of worm screw.Like this, rotate hand wheel rotating, can pass through worm drive turbine rotation, and then drive all fire grate major axis to rotate.Because worm and gear has larger transmitting ratio, therefore, can alleviate significantly operator's working strength, worm and gear has self-locking action simultaneously, can avoid any rotation of fire grate major axis.Certainly, we also can arrange in the end of worm screw a motor, to realize the automatic removing of cinder.
It should be noted that, the number of teeth of the transmitting gear on every fire grate major axis can be all identical, thereby make all fire grate major axis there is identical rotational angle, and the direction of rotation of adjacent two fire grate major axis, like this, when needs are removed cinder, we can rotate by the positive and negative both direction of manual or electronic control fire grate major axis, on adjacent two fire grate major axis, the original horizontal ratch of relatively arranging synchronously rotates inclination, on the one hand, ratch stirs, shear and broken cinder, be broken into compared with the cinder of fine grained chippings in the water tank that drops to below the gap between the adjacent ratch of same fire grate major axis.On the other hand, the space on adjacent fire grate major axis between relative ratch progressively becomes greatly, and broken cinder can promptly be fallen from the gap between the relative ratch of adjacent two fire grate major axis.When cinder cleans out, we can make fire grate major axis turn to original state, thereby guarantee that the both sides of fire grate major axis have respectively the ratch of a row level.
Further, the number of teeth of the transmitting gear on every fire grate major axis can be not identical yet, thereby make adjacent fire grate major axis have different velocities of rotation.For example, the number of teeth of the transmitting gear the odd number root fire grate major axis from a side to opposite side in fire grate is two times of the number of teeth of the transmitting gear on adjacent even number root fire grate major axis, thereby make the rotating speed of even number root fire grate major axis, is two times of odd number root fire grate major axis rotating speed.That is to say, in fire grate, the velocity of rotation of the fire grate major axis of the even number root such as the second, the 4th, the 6th and rotational angle are the velocity of rotation of the fire grate major axis of the odd number root such as the first, the 3rd, the 5th in fire grate and two times of rotational angle, thereby between adjacent fire grate major axis, form a speed discrepancy, and then be conducive to ratch on fire grate major axis cinder is formed to stronger shearing action, improve the efficiency that cinder.
