Abstract
The utility model discloses a vertically-staggered cross mechanical fire grate which comprises two groups of fire grates, wherein the two groups of fire grates are vertically installed at two sides of a garbage incinerator body above a slag bucket; the first group of fire grates and the second group of fire grates are staggered; the front end of each fire grate is pointed; the tip of each fire grate is fixedly connected with a bar-shaped plate; and the tail part of each fire grate is connected with an oil pressure piston by a connecting rod. The vertically-staggered cross mechanical fire grate is designed for garbage to vertically move in the incinerator and can adapt to the characteristics of complex ingredients without sorting and high moisture of city garbage in China; besides, the vertically-staggered cross mechanical fire grate has the advantages of simple structure, good durability and few faults and is convenient to maintain; and with the adoption of the vertically-staggered cross mechanical fire grate, thick-layer combustion of the garbage is realized, air for combustion can be prevented from shortage, the fire grate can be prevented from damaging by high temperature, and flame can be favorably diffused.
Description
Technical field
The utility model relates to a kind of fire grate of incinerator, is specifically related to staggered up and down fork-shaped stoker fired grate.
Background technology
The main mode of garbage disposal has landfill, biological compost and burning.In Europe 10～15 years from now on directly landfill waste will be under an embargo in principle.China's incineration treatment of garbage is just at the early-stage.The report of Chinese environmental industry is pointed out, the general trend of garbage disposal development is: the regeneration on the categorised collection basis more and more comes into one's own, ratio progressively improves, the standard of garbage loading embeading will be more and more higher, the ratio of landfill progressively descends, waste incineration is with stable development, and the ratio of waste gas of incineration generating rises to some extent.
In refuse burning system, burning fire grate is a most critical equipment.Can the technique influence rubbish that burn fire grate completing combustion, does not fire organic components content height the ashes of discharging and from the heat recovery efficiency of rubbish in body of heater, and influence sanitary landfills, to the pollution of environment.In order to allow the rubbish in the incinerator can be fully and completing combustion, reduce the hot igloss amount of ashes simultaneously, require as far as possible rubbish can fully be contacted with combustion air, reach the purpose of completing combustion, the while does not increase the body of heater volume again as far as possible.Chinese patent CN101476732A discloses a kind of oscillating type pushing mechanical grate of the applicant, it is by being made up of three sections fire grates of dry fire grate, combustion grate, after-combustion fire grate of drop each other, every section fire grate constitutes downward-sloping movable fire grate of step and fixed grate, an all fixedly connected hydraulic piston on the movable bracing frame under each movable fire grate by the interlaced arrangement of fire grate segment; The cutting mixer that the some fan-shaped cutting blades of evenly installing on installing by linkage and driven shaft on the combustion grate constitute, the flipover smoke consumer that the turning mechanism on combustion grate afterbody installation kit oil scraper pressure piston, driving shaft, drive rod, driven shaft, driven shaft constitutes.It is basic along laterally moving in different fire grate sections burnings with rubbish, thereby improves efficiency of combustion, has China's municipal refuse complicated component, simple in structure, easy to maintenance, the characteristics that fault is few of adapting to.
Summary of the invention
It is a kind of at the primary domestic waste complicated component of China that the purpose of this utility model is to provide, and the characteristics that refuse classification is handled are not carried out in most of area, rubbish vertical direction in burning body of heater moves, and can improve the staggered up and down fork-shaped stoker fired grate of efficiency of combustion.
For achieving the above object, the staggered up and down fork-shaped stoker fired grate of the utility model comprises two groups of fire grates, described two groups of fire grates are installed in the waste incineration body of heater both sides of slag bucket top one on the other, and the fire bars of first group of fire grate and second group of fire grate is staggered, described fire bars front end is pointed, each fire bars is most advanced and sophisticated fixedlys connected with stripe board, and the afterbody of fire grate is connected with hydraulic piston by connecting rod.
Because technique scheme is designed to fork-shaped with fire grate, and be installed in the body of heater both sides and be up and down relatively staggered, rubbish is along with the periodicity of the fork-shaped stoker fired grate that interlocks is up and down opened and closed, move from top to down with vertical direction, rubbish on the staggered up and down fork-shaped stoker fired grate is divided into main burning zone from top to bottom, completing combustion layer and stop combustion zone.Along with the periodically Push And Release of fork-shaped stoker fired grate that interlocks up and down, stop burning zone and be moved to fork-shaped stoker fired grate below, the completing combustion layer becomes the stop burning zone, and main burning zone becomes the completing combustion layer, and the rubbish that newly replenishes into becomes main burning zone.Combustion air rises by the gap between the fire grate from the fork-shaped stoker fired grate bottom that interlocks up and down, and the combustion air that has pressure can float rubbish, and is loose, improved the contact probability of air and rubbish, helps the completing combustion of rubbish.Therefore, the utlity model has following obvious advantage: can adapt to China's municipal refuse complicated component, not have letter sorting, the characteristics that moisture is high; Simple in structure, durability, easy to maintenance, fault is few; Realize the burning of rubbish thick-layer, and can prevent the short circuit of combustion air that prevent fire grate by the high temperature scaling loss, the flare diffusion is good.

Fig. 1 is the staggered up and down fork-shaped stoker fired grate planar structure schematic diagram of the utility model;
Fig. 2 is the front view of embodiment shown in Figure 1;
Fig. 3 is the side view of embodiment shown in Figure 1;
Fig. 4 is the staggered up and down position view of fork-shaped stoker fired grate in incinerator of the utility model.
The specific embodiment
By Fig. 1, Fig. 2 and Fig. 3 as seen, the staggered up and down fork-shaped stoker fired grate of the utility model comprises two groups of fire grates, two groups of fire grates are installed in the waste incineration body of heater both sides of slag bucket 1 top one on the other, and the fire bars 2 of first group of fire grate and second group of fire grate is staggered, fire bars 2 front ends are pointed, fixedly connected with stripe board 3 in each fire bars 2 tip, the afterbody of fire grate is connected with hydraulic piston 5 by connecting rod 4.
Referring to Fig. 4, the utility model is the operation principle of staggered fork-shaped stoker fired grate up and down: closed by the fire grate of hydraulic piston 5 actions with waste incineration body of heater both sides earlier, when rubbish when garbage inlet 6 is slipped on the fire grate, the high temperature air that top blast comes under the fire grate is by stopping burning zone, completing combustion layer and main burning zone burn rubbish.Because combustion air pressure makes the stop burning zone, the waste layer of completing combustion layer and main burning zone is loosening, and produces flow regime, has promoted venting capability, and air being more evenly distributed in rubbish kept the smooth combustion in the incinerator.When the rubbish of completing combustion layer in the basic afterburnt, by hydraulic piston 5 actions fire grate is opened again, rubbish after the burning vertically drops in the interior flipover smoke consumer 7 of slag bucket, proceed completing combustion at this, after meeting the requirements of hot igloss amount, flipover smoke consumer 7 stirs, and lime-ash is discharged to ash cooling tank by managing ash 8 down, is gone out by the scraper plate machine conveyor delivery in the ash cooling tank again.
