Major advantage of the present invention is as follows:
1), the present invention abandons traditional direct by air vent aperture being opened in fire grate isostere upward, and many defects such as the such as air vent blocking caused.On the one hand, with the same angular slope of some fire grate plate monoblocks and exist certain altitude difference arrangement, to form the step structure of isostere, not only ensure that material is advanced along the accessible of isostere and burn, simultaneously also naturally define blowing direction and material direct of travel vent aperture in the same way constructs.Vent aperture is lain across and has been covered with the above-mentioned step surface of isostere, and material one edge isostere is advanced and constantly fallen and stirs, and is subject to constantly brushing and efficient burning of side vent aperture place wind-force while falling.And on the other hand, while above-mentioned vent aperture is formed, then be aided with the horn-like air guide hole of the Eight characters that extension board formed, to guarantee the maximization of vent aperture place air-out wind-force.Even if there is the material slag particle of dust granules shape, its along isostere face of burning advance and while constantly falling stand up at its step surface place, once just can be blown away rapidly by the high-speed wind power at this place near vent aperture, thus ensure that the smoothness of this place's vent aperture.The fit structure of its fire grate plate and extension board is very simple, and without the need to complicated project organization, succinct reinforcing rib structure of arranging in pairs or groups, to guarantee the rigidity of structure of vent aperture, can ensure that the normal reliable of whole fixed grate is run.Fire grate wind-force unimpeded, also just ensure that the constant and controllability of incineration temperature in whole combustion chamber, and then also just improves its actual burning usefulness.
2), the concrete bearing of trend of extension board, only need form with fire grate plate " eight " shape wind-guiding construct possessing angle.In fact, extension board is horizontal panel structures by the present invention, and constitutes one-piece construction with fire grate plate.When producing and make, by the whole fire grate unit of its one-body molded formation; During assembling, more above-mentioned fire grate unit is carried out modularization installation; Change maintenance obvious also more convenient.The substrate framework structure of similar " well " font that main reinforcement and cross-tie are formed, further can promote the force-bearing property of fixed grate, thus guarantees its functional reliability when high strength waste incineration.Even can take the circumstances into consideration the secondary reinforcement that the more tiny small-sized plate body of interpolation structure is formed at above-mentioned vent aperture place, to promote the work rigidity at vent aperture place further.
3), the layout of blanking table top, be obviously more conducive to firing efficiency when improving material burns.In fact, because isostere of the present invention itself is staircase structural model, also namely when material is advanced along a upper fire grate plate and dropped on next fire grate plate by vent aperture place, himself ensure that material to a certain extent stands up action.And consider when burning the formation bed of material that material is too much or volume is excessive and crust, the layout possessing the blanking table top of larger blanking difference is herein also just obviously more necessary.Blanking table top can be taken the circumstances into consideration to arrange one or more according to actual conditions, stand up burning demand with what guarantee material.
4), on the basis of above-mentioned fixed grate structure, present invention also offers corresponding incinerator structure, burn usefulness to promote it.On the one hand, for " eight " shape air guide hole structure of fixed grate, adopt air intake direction directly to point to the air inlet structure at its air guide hole place, thus ensure that the maximization of vent aperture place air-out wind-force.On the other hand, adopt fire grate push rod structure, and be no longer traditional stirring wheel structure, not only achieve and the effect of getting through is worn for the nail that " shell " shape on fixed grate burning face is material bed, to guarantee the efficient burning function of this incineration section place material; Simultaneously, consider the inclination row face structure of the obstructiveless of isostere, too fast and cause burning incomplete once material gait of march, by the lift motion of fire grate push rod, make it lie across more than the burning face of fixed grate with certain altitude, thus play the artificial effect forming obstacle face, with by slowing down material gait of march, and reach the function guaranteeing its comprehensive after-flame, achieve many things at one stroke.
5), for the through hole of fire grate push rod guiding, be arranged in the lower end of fire grate plate with extension board junction.In other words, the jacking action of fire grate push rod is betide the distalmost end place that this fire grate plate place wind-force brushes direction all the time, is also the distalmost end place of the vent aperture at its this place relative.Like this, not only make its push rod lining have the fixed function of two adjacent fire grate plates and extension board when mounted concurrently, also can not burn the hot blast course generation interference at face place to fixed grate, to promote its air-out efficiency simultaneously.
6), the layout of weight is also very important.As everyone knows, what fire grate push rod was done when jacking is useful work.And when falling, complete because the material bed perforation of " shell " shape is stirred, if at the uniform velocity return again, its time of staying in combustion chamber certainly will be comparatively of a specified duration, and this can increase the heat time of fire grate push rod in combustion chamber, is worthless.The present invention utilizes weight, actual in increase the weight of the arrangement of beam, inoperative when useful work is made in the jacking of fire grate push rod, guarantees that fire grate push rod can penetrate that " shell " shape is material bed carries out punch operation.And when fire grate push rod falls and makes idle work, under power part self power coordinates the gravity increasing the weight of beam to accommodate, fire grate push rod can be fallen by " acceleration ", thus decreases the heating cycle of fire grate push rod, also just avoids the meaningless too much heating of fire grate push rod in combustion chamber.Certainly, when specifically using, even can use increasing the weight of beam self to be re-used as the limited block of spacing fire grate lift rod stroke, thus make it have concurrently spacing and increase the weight of two kinds of functions, achieve many things at one stroke.
4), the minimum altitude of the top end face of fire grate push rod, also namely ensure that the minimum altitude of fire grate push rod when backhaul.Under normal condition, when the present invention is in minimum altitude with the top end face of fire grate push rod, its altitude line is positioned at the inclined-plane place, burning working face place of fixed grate.Namely also fire grate push rod top end face is concordant with above-mentioned burning working face, thus when material is entered from the import of fixed grate, can burning along gravity fall under the same domatic gradient of fixed grate at the uniform velocity all the time.As highly too low within even its top is absorbed in fire grate lining after the backhaul of fire grate push rod, material can be caused on the contrary directly to enter through hole place residing for fire grate lining, thus affect each structure and normally work.
6), fire grate push rod is clouded on fixed grate with multiple.Arrange according to normal matrix, herein then with each row respectively arrange carry out transverse and longitudinal arrange to form Rectangular Matrix structure, with realize for the material spread all on the burning working face of fixed grate without dead angle bore a hole effect.The actual act mode of fire grate push rod can deliberately be arranged, also arbitrarily can carry out lifting action to single fire grate push rod in independent power portion.The present invention is preferably with the often capable horizontal fire grate push rod unit of lateral arrangement for synchronization action mechanism, often capable horizontal fire grate push rod unit all " independence " actions.Rely on artificial or software control, only control certain often capable horizontal fire grate push rod unit action wherein when needed, the heat waste phenomenon caused to avoid meaningless excessive burning.
7) that, sees fiery operating room is set to an emphasis of the present invention.As everyone knows, current fire grate stirs assembly, is all omnidistance to stir action by circulation voluntarily, ensures uninterruptedly to stir object for material on its burning face.Meanwhile, the burning for material on its burning face is observed, be then all in incinerator, only arrange some sensors carry out simple temperature sense.Point-to-point monitoring temperature, perfectly can not control the burning process of whole burning face place material.The present invention is directly arranged in combustion chamber bottom side-walls with observation window, by looking up from bottom to top, realizes the naked-eye observation object of fixed grate being burned to face place material.In conjunction with the push rod component of above-mentioned self contained function, when finding that wherein material burns poor effect because of the crust factors such as layer thickness is blocked up in somewhere, the push rod component directly controlling this place produces knocks over action.Its operating flexibility is strong, traditional automatic component can be effectively avoided excessively to stir material, and Sheng and thermal waste phenomenon are crossed in the burning caused, to guarantee that its each divided combustion calorific value all can be made the best use of everything, finally ensure that and can reach its optimal balance point between material firing efficiency and its heat utilization rate.
