Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention will be further described.
As shown in Figure 1 and Figure 2, a kind of coal cinder burner, comprises a combustion gasification body of heater 1 and corresponding automatic stoking mechanism 2, and this combustion gasification body of heater crown center position is provided with the coal mouth of pipe 11, on one sidewall of combustion gasification body of heater, bocca 12 is set, corresponding fire door 13 is set on another sidewall.Automatic stoking mechanism drops into fire coal in combustion gasification body of heater from the coal mouth of pipe, sprays, to be the heating such as follow-up corresponding Equipment for Heating Processing, kiln at the gas burner that forms high temperature after burning, gasification from bocca.
Automatic stoking mechanism comprise be arranged on combustion gasification body of heater side fluctuating orbit 21, be positioned at fluctuating orbit lower end for the trailer 22 of carrying fire coal and be positioned at fluctuating orbit upper end for pulling the traction machine 23 of trailer, hoist ropes 231 on traction machine is connected with trailer, like this, traction machine rotates and can pull trailer to rise along fluctuating orbit.
For the fire coal in trailer is sent in combustion gasification body of heater, we can arrange at combustion gasification body of heater top a cooling water jecket 14 around the coal mouth of pipe, and be positioned at cooling water jecket side place at combustion gasification body of heater top a defeated coal auger 3 is set, defeated coal auger top is provided with bunker 31, the upper end of bunker is provided with capping 32, and near fluctuating orbit one side, an automatically controlled hermatic door 33 that can automatic shutter is set in capping, thereby make the coal mouth of pipe generally in closed state, the discharging opening of defeated coal auger is connected with the sidewall of cooling water jecket.Like this, the fire coal in trailer is being poured into by hermatic door after the bunker of defeated coal auger, and the helical blade of defeated coal auger can promote fire coal and be sent in cooling water jecket from discharging opening, and enters in combustion gasification body of heater by the coal mouth of pipe.
Fire coal in combustion gasification body of heater is extreme temperatures in the time of combustion gasification, and therefore, we need to make the upper end closed of cooling water jecket, avoids the flue gas of high temperature to leak.In addition, the coal mouth of pipe is made up big and down small bellmouth, an automatically controlled seal cones 4 that can automatic lifting is set on the top of cooling water jecket simultaneously, sealing cone adopts refractory material to make, the profile of seal cones and the coal mouth of pipe are suitable, like this, in the time that coal finishes, seal cones can automatically decline and make coal ferrule, thereby avoid the high temperature in combustion gasification body of heater to be delivered on defeated coal auger by coal feeding pipe oral instructions, guarantee that defeated coal auger can normally work, realize the automatic stoking under coal cinder burner duty, keep the stable of the interior temperature of combustion gasification body of heater simultaneously.
In order effectively to control the action of trailer, defeated coal auger, hermatic door, we can arrange a controller, and corresponding travel switch is set on fluctuating orbit, and the level detector that can detect Coal-fired capacity is set simultaneously in the bunker of defeated coal auger.Like this, when the fire coal in bunker is during lower than set amount, level detector can send signal to controller, controller controls traction machine work rises trailer, and in the time that trailer arrives fluctuating orbit upper end, travel switch sends signal to controller, controller is controlled hermatic door and is opened, now trailer is turning fire coal to be poured in bunker by hermatic door, and then trailer declines, and hermatic door is closed.And so forth, until the fire coal in bunker arrives set amount.Defeated coal auger can be set the corresponding working time according to combustion gasification body of heater internal combustion the consumption of coal, in time deliver fire coal in combustion gasification body of heater.In the time that defeated coal auger need to be started working, thereby first controller controls seal cones, the coal mouth of pipe is opened in rising, now defeated coal auger work, and fire coal can be sent in cooling water jecket, and falls in combustion gasification body of heater by the coal mouth of pipe.In the time that defeated coal auger quits work, controller is controlled seal cones decline and is blocked the coal mouth of pipe, thereby makes combustion gasification body of heater keep sealing state.Certainly, in cooling water jecket, also need to arrange corresponding temperature sensor, to control the temperature of cooling water in cooling water jecket.
In order to realize coal-fired full-automatic delivery, as Fig. 1, shown in Fig. 3, fluctuating orbit 21 comprises left track 211 and the right track 212 of inclination, the open side of left track and right track is oppositely arranged, left track and right track are progressively close towards combustion gasification body of heater one side from bottom to up, thereby left track and right track form upset track 24 in the upper end near hermatic door towards hermatic door one side arc-shaped bend, and in the left side of left track upper end and the right side of right track upper end, the guide bar 25 of taking advantage of a situation and being inclined upwardly and extending is set respectively, that is to say, the angle of inclination of guide bar is with left, the angle of inclination of right track is identical.Correspondingly, the opening of trailer 22 is large, and bottom is little, thereby is inverted trapezoidal on longitudinal cross-section, and the angle of inclination of an one sidewall tilting and left and right track is roughly the same.In addition, the upper turning cylinder 221 of a level is set on the top of this sloped sidewall of trailer, and at the two ends of upper turning cylinder, pulley 26 is set respectively, two pulleys are slidably connected at respectively in left track and right track, the lower turning cylinder 222 of a level is set in the bottom of this sloped sidewall of trailer simultaneously, and 27, two rollers of roller are set respectively at the two ends of lower turning cylinder are slidably connected to form on abutting on left track and right track away from the lateral surface of combustion gasification body of heater one side.In addition, we also can connect an enhancing ring 28 in the hoist ropes end of traction machine, this enhancing ring is made up of the ring body of U font and the lifting arm being connected in the middle of ring body, and two openends of ring body are rotationally connected with the two ends of lower turning cylinder respectively, and hoist ropes is connected on lifting arm.
In the time that we need coal, can in trailer, pack fire coal into by manual type, or also can realize automatic loading of coal by belt conveyor one class device.Now two of the top of trailer pulleys are positioned in left and right track, and two rollers of trailer bottom abut on the lateral surface of left and right track only.In the time that traction machine is worked, hoist ropes pulls trailer to rise by enhancing ring, lower turning cylinder, and now two pulleys roll in left and right track, and two rollers roll on the lateral surface of left and right track.In the time that trailer rises near hermatic door position, hermatic door is opened, two pulleys on trailer top are taken advantage of a situation and are entered and the smooth upset track being connected of left and right track, thereby the openend of trailer is tilted towards hermatic door, two rollers of trailer bottom continue to scroll up along guide bar, the bottom of trailer is raised gradually, thereby make progressively inclination flip of trailer, fire coal is poured in the bunker on defeated coal auger top.Then hermatic door is closed, traction machine rotates backward, the bottom of trailer can progressively decline under the effect of self gravitation, the roller of trailer bottom is now rolled on left and right track again, the pulley on trailer top exits in track and gets back in left and right track from upset, and last trailer declines until get back to initial position.So repeat, can be to the fire coal of delivering set amount in bunker.
As Fig. 1, shown in Fig. 2, the furnace wall of combustion gasification body of heater of the present invention adopts hollow structure, a diaphragm plate 15 is set between interior outer furnace wall, thereby make inner upper annular passage 16 and the lower annular passage 17 of forming in furnace wall, the top of upper annular passage arranges air inlet, air inlet is connected with blower fan by pipeline, on diaphragm plate, arrange in connection, the connected entrance of lower annular passage, some oblique air nozzles 18 are set simultaneously on the internal protecting wall of combustion gasification body of heater, tiltedly air nozzle is equidistantly arranged ringwise on internal protecting wall, tiltedly air nozzle tilts in the shape of a spiral, its one end is communicated with lower annular passage, the burner hearth of the other end and combustion gasification body of heater is communicated with.When blower fan work, first the high velocity air of blower fan ejection enters in upper annular passage by air inlet, and form high speed circling gas flow, make the internal protecting wall of combustion gasification body of heater be able to cooling on the one hand, make high velocity air be able to preheating simultaneously, circling gas flow enters in lower annular passage by the connected entrance on diaphragm plate again, and helical form sprays the lower furnace portion that enters into combustion gasification body of heater from air nozzle, makes the fired coal combustion gasification in burner hearth.Certainly, we also can arrange spiral helicine deflector (not shown) in upper annular passage, thereby make annular passage form spiral helicine air channel, be conducive to improve the heat exchanger effectiveness between high velocity air and internal protecting wall, guarantee that internal protecting wall maintains suitable temperature.Further, the connected entrance on diaphragm plate can arrange multiple, and equidistantly arranges ringwise, thereby the high velocity air in annular passage can be entered in lower annular passage rapidly, equably.
Further, the present invention arranges a water tank 5 being communicated with combustion gasification body of heater in the bottom of combustion gasification body of heater, and a side of water tank arranges a slag notch 51 upward.Like this, the cooling water 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, fire grate 6 is set to support fire coal at combustion gasification body of heater and water tank junction, water tank can be used as sludge-store cabin chamber for storing remaining cinder after coal cinder combustion gasification.Remove cinder in order to realize not blowing out, fire grate comprises some fire grate major axis 61 of flatly equidistantly arranging, on two sidewalls of water tank, corresponding bearing block is set, the two ends of fire grate major axis are rotatably connected on bearing block, some disintegrating slag tooth groups 62 are set on fire grate major axis vertically equally spacedly, this disintegrating slag tooth group is made up 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 cross.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 4, 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 every group of disintegrating slag tooth group is made up of the ratch of even number, 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, must form the ratch of a row level at the opposite side of fire grate major axis 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.In the time that 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, in the time that fire grate major axis rotates, its originally the ratch of level progressively tilt, thereby and distance between 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.Arrive when a certain amount of when being deposited on the cinder of water tank bottom, can cinder be cleaned out from the slag notch of water tank one side.Because cinder has higher heat, therefore, cinder can make cooling water vaporization rise in the time falling into the cooling water of water tank, entering into the gasifying agent 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 level controller in water tank, to guarantee that the water level in water tank remains on rational level.
Certainly, as shown in Figure 5, 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, in the time that 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 cooling water 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 cooling water 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 outer 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, in the time that 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 cooling water in water tank also can play the effect of cooling fire grate, to extend the service life of fire grate.For this reason, cooling water 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 cooling water underwater of water tank, heat on fire grate can promptly pass to the cooling water 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 cooling water in water tank, and then can promote to fire coal gasification.It should be noted that, we can be a heat radiation pond of cooling water jecket configuration at combustion gasification body of heater top, water return pipeline on cooling water jecket is connected to the top in heat radiation pond, and inlet pipeline on cooling water jecket is connected to the bottom in heat radiation pond, thereby between cooling water jecket and heat radiation pond, form a closed circuit, to the cooling water in cooling water jecket can be dispelled the heat by heat radiation pond.Particularly, we also can arrange on the top in heat radiation pond the supply channel of a connection water tank, so that heat radiation pond is cistern water supply, in heat radiation pond, corresponding water level controller are set simultaneously, and the bottom in heat radiation pond arranges corresponding cooling water water pipe.Due to temperature in heat radiation pond compared with high cooling water proportion compared with gently floating on upper strata, the cooling water that temperature is lower is sunken to lower floor, like this, the high-temperature cooling water flowing back to from the water return pipeline of cooling water jecket enters the top in heat radiation pond and floats on upper strata, meanwhile, temperature higher cooling water in upper strata constantly enters into the cooling water with subsidiary water tank in water tank from the supply channel on the top that is arranged on heat radiation pond, thereby is conducive to the vaporization of cooling water in water tank.The cooling water water pipe of heat radiation basin bottom correspondingly adds to fresh cooling water lower temperature in heat radiation pond, thereby the cooling water of the pond lower floor that is conducive to make to dispel the heat maintains a suitable temperature, the cooling water of lower floor enters in cooling water jecket by the inlet pipeline of heat radiation bottom, pond, makes cooling water jecket maintain a lower temperature.
For the convenient cinder of removing, fire grate major axis can be associated with a drive unit (not shown), for example, directly drives fire grate major axis with motor, makes each fire grate major axis can independent rotation, to alleviate operating personnel's working strength.Or drive unit comprises the travelling gear being arranged on the outer end that fire grate major axis stretches out water tank, and intermeshing between travelling gear on adjacent two fire grate major axis.Like this, in the time that a fire grate major axis rotates, can drive all fire grate major axis to rotate by intermeshing travelling gear simultaneously, thereby can promptly remove cinder, increase work efficiency.Certainly, now we can go to drive a fire grate major axis wherein with a motor or other power set, or also can drive fire grate major axis to rotate by manual mode.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 worm gear, correspondingly, the worm screw engaging with worm gear is set rotationally on the lateral wall of water tank, and a rotation handwheel is set in the end of worm screw.Like this, rotate hand wheel rotating, can rotate by worm drive worm gear, and then drive all fire grate major axis to rotate.Because worm and gear has larger gearratio, therefore, can alleviate significantly operating personnel'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 travelling 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, in the time that 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 in the water tank that drops to below compared with the cinder of fine grained chippings 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.In the time that 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 travelling 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 travelling 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 travelling gear on adjacent even number root fire grate major axis, is two times of odd number root fire grate major axis rotating speed thereby make the rotating speed of even number root fire grate major axis.That is to say, in fire grate second, the 4th, the velocity of rotation of the fire grate major axis of the even number root such as the 6th and rotational angle be in fire grate first, the 3rd, the velocity of rotation of the fire grate major axis of the odd number root such as the 5th 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 shear action, improve the efficiency that cinder.
Finally, as shown in Figure 1, we also can arrange the drill rod passage 7 that connects burner hearth on the sidewall of combustion gasification body of heater, and an end cover is set in the outer end of drill rod passage.After operation certain hour, coal-fired meeting coking on the inwall of combustion gasification body of heater, in the time of our blowing out, can open end cover, stretch into and in combustion gasification body of heater, smash the cinder of coking on the furnace wall of combustion gasification body of heater by drill rod passage with elongated drill rod.
