The specific embodiment

As shown in Figure 1 and Figure 2, the utility model gas generator, comprise burner hearth 4, be positioned at coal bunker 2 on the burner hearth 4, be positioned at the fire grate 5 of lower furnace portion, burner hearth 4 places in the water jacket 12, upper furnace has gas exit, be communicated with steam pipe 10 on the steam (vapor) outlet on water jacket top, steam pipe 10 enters the fire grate below after merging with blast pipe 14, cyclone dust collectors 11 also are housed in water jacket, the air inlet of cyclone dust collectors is connected with gas exit on the burner hearth, burner hearth 4, water jacket 12 and cyclone dust collectors 11 all place on the base 15 of hollow, and slag notch 16 is arranged on the base 15.Also can be outside water jacket 12 again coated with insulation material 13.

One ring raceway seat 7 is housed in base 15, raceway seat top is raceway 7a, ball 24 is housed on the raceway 7a, the degree of depth of raceway 7a is greater than the radius of ball 24, place an annular fluted disc 6 on the ball 24, fluted disc 6 lower surfaces have a bulge loop 25, and bulge loop 25 also contacts with ball 24 and corresponding circular arc is all made on ball 24 contacted surfaces; The tooth of fluted disc 6 is meshed with gear 8, and the other end of the gear shaft 20 of this gear 8 extends outside the base, and can link to each other with crank, also can link to each other with the reductor by driven by motor; Like this, because the effect of bulge loop, raceway 7 can bear axial load and radial load simultaneously, and has good positioning, and is wear-resistant.

As shown in Figure 3, fire grate 5 is turriform, is formed by stacking from bottom to top by two annular column plates 23 and a taper tower cap 21, and there is the cinder hole of falling at column plate 23 middle parts, between the column plate, all have three columns 22 that both are connected between column plate and tower cap, fire grate 5 is the upper surface that certain degree of eccentricity is contained in fluted disc 6.Certainly, column plate can have three or more, and column also is not limited to three.

As shown in Figure 4, tower cap 21 upper surfaces are equipped with dreg scraper knife 19, and that can improve fire grate scrapes the slag effect.

As shown in Figure 5, coal bunker 2 is cylindrical, the coal bunker fixed bin lid 28 that is equipped with suitable for reading has coal filling hole 26 on the fixed bin lid 28, and movable storehouse lid 1 is equipped with at the coal filling hole place, cloth coal mouth 30 is arranged on the coal bunker base plate 29, fixed bin covers 28 central authorities rotating shaft 31 is housed, and control stick 18 is equipped with in the rotating shaft upper end, and the rotating shaft lower end installs an inner cap 3, inner cap 3 contacts with base plate 29, has on the inner cap 3 and the corresponding coal falling hole 27 in cloth coal mouth position.As shown in Figure 6, each cloth coal mouth 30 is fan-shaped, be evenly distributed on the coal bunker base plate 29, and coal falling hole 27 and cloth coal mouth 30 similar shapes on the inner cap 3, for playing the effect of sealing, the area of the entity between adjacent cloth coal mouth should be greater than the area of single cloth coal mouth.

On the movable storehouse lid 1 handle 19 is housed, movable storehouse lid 1 is journaled in the rotating shaft 28.

The utility model in use, cloth coal mouth on the coal bunker base plate 29 30 is the dislocation state with coal falling hole 27 on the inner cap 3, the coal gas in the burner hearth 4 can only enter the cyclone dust collectors from gas exit, after dedusting, clean quiet coal gas is sent from the delivery outlet 9 of cyclone dust collectors.When the needs coal, pull handle 17, open movable storehouse lid 1, coal is added coal bunker, the activity Cang Gai that closes then pulls control stick 18 again, rotates inner cap 3, makes coal falling hole and the cloth coal is salty closes, and then the coal in the coal bunker 2 enters in the burner hearth from cloth coal mouth.So cycling, coal gas does not leak in the time of can guaranteeing coal, and can continuous gasification.Because cloth coal mouth is even setting, the coal that therefore falls into burner hearth also can be evenly distributed.

Coal in the burner hearth is the possibility slagging scorification in combustion process, therefore answer transmitting gear 8, the fire grate 5 that drive is packed on the fluted disc 6 rotates, then be eccentric column plate of placing 23 and hearth wall acting in conjunction, with big slag fragmentation, disintegrating slag with the space of ashes between column through the water that the cinder hole that falls is fallen in the base to be contained, slag accumulate a certain amount of after, can draw out from slag notch 16.

In the burning of coal process, the water in the water jacket has part can become steam to enter in the steam pipe 10, and under the effect of blower fan, from ajutage along with air together in fire grate enters burner hearth, generate coal gas with coal reaction back.
