Description
Technical field
The utility model relates to a kind of charging gear that prevents tempering, relates to the charging gear that the biomass-burning fuel boiler prevents tempering specifically, can be widely used in biomass-burning etc. and be easy to generate in the field of boilers of tempering fuel.
Background technology
Along with the reserves minimizing of fossil energies such as coal, oil, natural gas, Renewable Energy Development has become global hot issue.Characteristics such as renewable, low pollution that biomass energy has, distribution is wide, total amount is very abundant.Can partly substitute fossil energy, optimize the energy supply structure, reduce the CO2 discharge capacity, alleviate greenhouse effects and threaten.Therefore the development and use of biomass energy can produce considerable energy saving, environmental protection and social benefit.At present boiler exists when firing biomass fuel and is easy to generate tempering in the combustion process, in loading hopper, burns, and burns out hopper and whole feeding system when serious, makes normally feed of boiler, has had a strong impact on the safe operation and the economic benefit of boiler.
Summary of the invention:
It is fast that the purpose of the utility model is to solve existing biomass fired boiler burning velocity, and tempering easily causes the problem of material burning in the hopper, thereby a kind of boiler backfire-proof material feeding device is provided.
The technical scheme that provides according to the utility model; The biomass-burning fuel boiler prevents that the charging gear of tempering from comprising fire grate, feed hopper, hopper support, material seeding airduct, lock glassware, feed pipe, reductor, and feed hopper passes through the hopper support fixation in the fire grate front upper part; The feed hopper bottom is provided with the lock glassware; The lock glassware links to each other with feed pipe, and the material seeding airduct is set on the feed pipe, and reductor is fixed on the dispenser side plate; Reductor links to each other with the lock glassware.
As the further improvement of the utility model, said lock glassware comprises axle, lock barrel, bearing, side plate, scraping blade, bearing block, sealing plate, and scraping blade is fixed on the axle; Axle one end is by bearings; The axle other end links to each other with the axle of reductor, and bearing is installed in the bearing block, and bearing block is fixed on the side plate; Sealing plate is equipped with at the axle two ends, and the lock barrel is fixed on the side plate.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Be easy to arrange that requisite space is little, manufacturing cost is lower, and is stable; Owing to adopt lock glassware and the double anti-backfire measure of material seeding wind, effectively prevent the problem of biomass fuel, thereby can prolong the service life of hopper in the hopper internal combustion, guaranteed the safe operation of boiler; Make evenly continuous supply of fuel simultaneously, regulate feeding coal, reduce operating cost, improved economic benefit according to boiler load.

Fig. 4 is A～A cutaway view of Fig. 3.
The specific embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
Like Fig. 1～shown in Figure 4, comprise that combustion chamber 1, feed hopper 2, hopper support 3, material seeding airduct 4, lock glassware 5 (axle 5-1, lock barrel 5-2, bearing 5-3, side plate 5-4, scraping blade 5-5, bearing block 5-6, sealing plate 5-7), access door 6, feed pipe 7, fire grate 8, reductor 9 etc.
The utility model feed hopper 2 supports 3 through hopper and is fixed in fire grate 8 front upper parts; Feed hopper 2 bottoms are provided with lock glassware 5, and lock glassware 5 links to each other with feed pipe 7, and material seeding airduct 4 is set on the feed pipe 7; The material that lock glassware 5 comes out is sent into combustion chamber 1 through feed pipe 7; Material seeding airduct 4 is set on the feed pipe 7, and reductor 9 is fixed on the charging gear side plate, and reductor 9 drives 5 runnings of lock glassware.Said lock glassware 5 comprises a 5-1, lock barrel 5-2, bearing 5-3, side plate 5-4, scraping blade 5-5, bearing block 5-6, sealing plate 5-7; Scraping blade 5-5 is fixed on the 5-1, and axle 5-1 one end is supported by bearing 5-3, and the axle 5-1 other end links to each other with the axle of reductor 9; Bearing 5-3 is installed in the bearing block 5-6; Bearing block 5-6 is fixed on the side plate 5-4, and axle 5-1 is equipped with sealing plate 5-7 in two ends, and lock barrel 5-2 is fixed on the side plate 5-4.
The utility model course of work and operation principle
During the utility model work biomass material is added feed hopper 2; Material gets into the lock glassware through lock glassware 5 upper inlets in the feed hopper 2; Reductor 9 drives scraping blade 5-5 rotation in the lock glassware; Scraping blade 5-5 promotes materials rotation in the lock glassware 5, when material rotates to lock glassware 5 bottom discharging openings, because deadweight drops down onto in the feed pipe 7 of lock glassware bottom, through deadweight and the material seeding wind that is arranged in the material seeding airduct 4 on feed pipe 7 tops fuel is delivered in the combustion chamber and is burnt.Can make material and combustion chamber 1 in the feed hopper 2 be in the state that is separated by scraping blade 5-5 in the lock glassware 5 all the time through lock glassware 5 feeds, can effectively prevent tempering.Make biological material under the blowing of material seeding wind, fall combustion chamber 1 fast through material seeding airduct 4 is set on the feed pipe 7, prevent that material from catching fire in feed pipe 7, and feed pipe 7 lower ends are reliably cooled off.
The utility model adopts lock glassware 5 and the dual anti-backfire measure of material seeding wind, effectively prevents the problem of biomass fuel in the hopper internal combustion.What of controllable rotation speed system feeding coal through regulating reductor make evenly continuous supply of fuel, have improved boiler operating efficiency, minimizing operating cost.
