Description

Multi-layer scraping rubbish slag grate frame incinerator

The utility model relates to a kind of multilayer backing-off cutting cinder grate frame incinerator body, and it belongs to municipal refuse incinerator.

At present, use the body of heater of refuse incinerator bigger, fire grate in its burner hearth is ladder overall fixed formula or slope overall fixed formula, this grate structure, in incinerating a large amount of rubbish processes, rubbish can not carry out scarifying, can not burn several times again, make on the fire grate rubbish of thick-layer can not get sufficient effectively air and supply with,, and produce public hazards once more so rubbish can not completing combustion.

In order to overcome the problem of above-mentioned existence, the purpose of this utility model, be to provide a kind of simple structure, effect significantly, the body of heater cost is low, can be with rubber, mould and flammable house refuse reaches the multilayer backing-off cutting cinder grate frame incinerator body that completing combustion no longer produces public hazards.

For realizing above-mentioned purpose, the utility model adopts the structure and the layering combustion process repeatedly of multilayer grate frame and bearing frame in the burner hearth of body of heater.The first floor is rotating grate frame, it forms by linking to each other with the transmission mechanism of oil pressure pump on the furnace outer wall, be provided with the multilayer bearing frame on the furnace wall below this grate frame, the rear end of each layer bearing frame contacts with the scoop of the corresponding oil compression rod actuating of fixedly connected oil pressure pump on the furnace wall separately respectively, under the control of timer, regularly the rubbish overturning of burning on the grate frame is burnt away to bearing frame, behind certain hour, again with the cinder that burnt on this bearing frame, push to descend again on one deck bearing frame by the scoop rake is diffusing, it is burnt away again, cinder successively pushes away successively down and burns away like this, and this measure can be accelerated the speed of incineration firing, can shorten the time of burning again, and reaching the purpose that rubbish completing combustion becomes ashes, its effect is remarkable.

The utility model is a kind of multilayer backing-off cutting cinder grate frame incinerator body, and it is made up of body of heater, burner hearth, grate frame, garbage inlet, smoke evacuation chimney, dedusting mouth, air outlet and device for igniting.Incinerator body dump rubbish the inlet lower end be provided with a rotating grate frame, this grate frame system closes with a cross bar with the furnace body outer wall rank and supports, link to each other with the rocking arm of oil pressure pump on being arranged on furnace outer wall in the one end, the grate frame turns into the skewed of 0～45 degree; Below the grate frame, also be installed with the bearing frame of multi-layer gate trellis on the corresponding furnace body wall with the low dip face, this bearing frame be located at furnace outer wall on push rod one end of oil pressure pump on scoop contact.Be installed in grate frame and bearing frame in the body of heater, its plane accounts for 3/4 area in body of heater cross section respectively, is the opening shape in the space of both front ends.Grate frame and bearing frame, the heating resisting metal lath by the longitudinal register bar is constituted respectively, leaves the space between each lath.The heating resisting metal lath can be made with heat resisting steel or heat-resisting alloy steel.

The utility model compared with the prior art, its advantage: rubbish can burn in burner hearth several times, and the rubbish of each burning all is subjected to scarifying, so both accelerated the speed of burning, shortened the time of burning again, reached the completing combustion of rubbish, its effect is remarkable, therefore, incinerator body can be realized miniaturization, and its floor space is also little, and the cost cost descends, easy and simple to handle, for ease of maintenaince.

Characteristics of the present utility model can also be further specified from the accompanying drawing of following examples.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:

Incinerator system of the present utility model is a square column bodily form that towers shape, its left upper end is provided with the inlet 2 of dumping rubbish of a chute formula, and the square column type body of heater has been piled into a firm heatproof wall by in-laws' refractory brick, account for 3/4 area in these 2 lower ends that enter the mouth between the inboard wall of furnace body face and supporting grate frame 5 by a cross bar 7, be articulated with a rocking arm 36 at outside cross bar 7 ends of body of heater, these rocking arm 36 other ends link to each other with oil pressure pump 27, and be driven by it, so whole grate frame 5 can be rotated and form inclined plane shape, its corner can be by 0～45 degree (shown in the drawing dotted line of Fig. 1).Grate frame 5(is as shown in Figure 2) body is by heat resisting steel or heat-resisting alloy steel, and file grid lath 16 is assembled, and side by side the front-end edge of grid lath 16 slightly is the curved arc shape, and keeps somewhere an opening 6 is arranged, and is used in and topples over the recrement of burning away the refuse.Be installed with the multilayer bearing frame 15 and 17 that slightly is the low dip shape in the suitable correspondence in the lower end of grate frame 5, be based in 3 outsides, furnace wall at this bearing frame 15 and 17 rearward end, be provided with front end with push rod 32 and be scoop 12 across formula, and outside the furnace wall, be articulated with a connecting rod 33 between 35 of oil pressure pumps, the connecting rod 33 that drives at oil pressure pump 35 moves push rod 32 forward, is dropped downwards by the front opening 20 or 21 of scoop 12 pushing burning recrements from its front end; Bearing frame 15 and 17(are as shown in Figure 3) the siege body account for 3/4 area of body of heater section, form side by side by many file laths, lath 16 is made by heat resisting steel or heat-resisting alloy steel, 16 of each laths have space 22, being convenient to air passes to quicken its burning, siege rear end rising wood is provided with the push rod 32 of scoop 12, and oil compression rod 35 connecting rod that articulates 33 that is installed in outside the body of heater is borrowed in the promotion of scoop 12 as previously mentioned.Moreover, having in the body of heater appropriate location and can install blowing plant, air blast is sent into burner hearth with wind through air outlet 4, to quicken incineration firing.

The mode of operation of present embodiment: will be through the rubber of sorting, mould and after flammable house refuse pulverizes, pour into by grate frame 5 from inclined tube garbage inlet 2 and to be accepted, combustible gas enters burner hearth through device for igniting rubbish is burnt, after urging the dried moisture content that accumulates in rubbish inside, 5 actuating plates by oil pressure pump 27 of grate frame change rocking arm 36, make it form inclined plane and rubbish in will burning, drop on the bearing frame 15 of correspondence from its front opening 6 and to continue again to burn, after a period of time burning, force push rod 32 reaches by connecting rod 33 displacements that are articulated on the oil pressure pump 35, the scoop 12 that is about to its leading section is moved forward, on the recrement of burning dropped thereunder corresponding bearing frame 17 from its front opening 20, do further fully burning, after making it burn into ashes, according to above-mentioned identical operations, open the surplus ash that is positioned on the adaptor 17 by scoop 12 rakes, fall into from lime-ash outlet 25 from its front opening 21 and to drop in furnace bottom, the flue dust that is generated in burning promptly up drains in the flue dust cleaning system through smoke evacuation chimney 31.

Above-mentioned

oil pressure pump

27,35 is to do overall operation via timer, pursues to make aflame rubbish also do stage stirring via the moving scoop of bearing frame rear end institute pivot, gets so that rubbish obtains sufficient air, makes its energy completing combustion.
