Abstract
The invention discloses a tempering-preventing feeding device for a biomass fuel fired boiler. The feeding device comprises a feeding hopper, a hopper support, a sowing air pipe, a locking device, a feeding pipe and a speed reducer, wherein the feeding hopper is fixed on the front upper part of a grate through the hopper support; the locking device is arranged on the lower part of the feeding hopper and is connected with the feeding pipe; the feeding pipe is provided with the sowing air pipe; the speed reducer is fixed on a side plate of the locking device; and the locking device comprises a shaft, a locking barrel, a bearing, the side plate, a scraping sheet, a bearing seat and a sealing plate. The feeding device has a simple, compact and reasonable structure, a small required space and low manufacturing cost, is easy to arrange and is stably operated; due to the two tempering-preventing measures of the locking device and the sowing air pipe, the problem that a biomass fuel is burnt in the hopper is effectively solved, the service life of the hopper can be prolonged, and the safe operation of the boiler is ensured; meanwhile, the fuel is uniformly and continuously supplied, feeding amount is adjusted according to the load of the boiler, operating cost is reduced, and the economic benefit is improved.
Description
Technical field
The present invention relates to a kind of charging gear that prevents tempering, relate 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, burns in loading hopper, 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 to the objective of the invention 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.
According to technical scheme provided by the invention, 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, 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.
As a further improvement on the present invention, described lock glassware comprises axle, lock barrel, bearing, side plate, scraping blade, bearing block, sealing plate, 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 the prior art the present invention has the following advantages:
The present invention 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.

The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As 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.
Feed hopper 2 of the present invention supports 3 by hopper and is fixed in fire grate 8 front upper parts, feed hopper 2 bottoms are provided with lock glassware 5, lock glassware 5 links to each other with feed pipe 7, 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 by 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.Described 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, axle 5-1 one end is supported by bearing 5-3, 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 course of work of the present invention and operation principle
When the present invention works biomass material added feed hopper 2, material enters 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 material rotation in the lock glassware 5, when material rotates to lock glassware 5 bottom discharging openings,, by 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 burnt because deadweight drops down onto in the feed pipe 7 of lock glassware bottom.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 by lock glassware 5 feeds, can effectively prevent tempering.Make biological material under the blowing of material seeding wind, fall combustion chamber 1 fast by 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 present invention 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 by regulating reductor make evenly continuous supply of fuel, have improved boiler operating efficiency, minimizing operating cost.
