Description

Vertical helical jacking bottom feed counter burning machine

Technical field

The utility model relates to a kind of novel combustion apparatus, the smokeless stove of particularly a kind of environment-friendly type vertical helical jacking bottom feed counter burning machine.

Technical background

Existing boiler or combustor, coal smoke and several poisonous carbonoxide to coal burning produced spread in the air, have greatly polluted environment, bring in various degree harm for people's living environment.

So, coal is fully burnt and do not produce coal smoke and pernicious gas, the one, the requirement of environmental law, the 2nd, targets that all industry and life stove designer must fall over each other to race.Chinese patent 01248518.7 and 01251369.5 discloses two kinds of kiln combustors, and the former does not have vertical screw conveyer, and coal can not raise up, and fully ratio of combustion is difficult; Though the latter has had vertical screw conveyer, coal can raise up, and coal can fully be burnt, and unreasonable structure cooperates not enough science, and mechanical performance is relatively poor, and maintenance difficulty is bigger.

Summary of the invention

The purpose of this utility model is to disclose a kind of coal and not only can but also raises up easily, and coal can fully be burnt, and the combustion space is more reasonable, and mechanical performance cooperates science, the vertical helical jacking bottom feed counter burning machine that goes slick.

For reaching the technical scheme that above-mentioned purpose adopts be:

Vertical helical jacking bottom feed counter burning machine is made up of burner hearth A, parallel defeated device for coal B, vertical defeated device for coal C and power set D.It is characterized in that vertical defeated device for coal C is installed in the burner hearth A, the bottom of burner hearth A is communicated with parallel defeated device for coal B; The axle of vertical defeated device for coal C is gone up fixing gear wheel 9.3, is connected with power set D by chain 10, reductor 12 and universal drive shaft 14; Parallel defeated device for coal B goes up fixing horizontal spiral follower and is connected with the decelerator 16 of power set D with wheel shaft 18.

Described burner hearth A, combustion chamber 25 has refractory material 23 last between combustion chamber and the furnace wall 24, has ventilative pipe 1.1 and 1.2 to pass furnace wall 24; Small room 6 burns in combustion chamber bottom, and wind hole 6.1 and ventilative pipe 6.2 are arranged on the burning plate of burning small room 6; The bottom of burning small room 6 rises coal bunker 7.

Described vertical defeated device for coal B, last, fixing with helical axis 9.2, gear wheel 9.3 is installed and be fixed with in the below of helical axis by upright spiral 9.1.

Described parallel defeated device for coal C, by the follower 18 on horizontal auger 13 of spirality and the horizontal auger 13 of spirality, and shell 11 constitutes, this shell one end is communicated with coal bunker 7 bottoms that rise of burner hearth A, the other end with add coal bunker 21 and be communicated with.

Described power set D is connected by the flywheel of driving-belt with reductor 16 by motor 19, is connected with the gear wheel 9.3 of vertical defeated device for coal B with universal joint 14 by reductor output wheel 15; Output wheel 15 by reductor 16 is connected with the follower 18 of parallel defeated device for coal C with chain 17 again.

As shown in Figure 1, 2.

Wherein: 1.1,1.2, ventilative pipe; 2, Supporting bucket; 3, platen; 4, body of heater; 5, seal diaphragm; 6, burn strickle; 6.1, the wind hole; 6.2, airduct; 7, rise coal bunker; 8, upright spool box; 9, vertical helical coal hoist; 9.1, conveyor screw; 9.2, helical axis; 9.3, gear wheel; 10, chain; 11, the horizontal auger shell of spirality; 12, reductor; 13, the horizontal auger of spirality; 14, universal drive shaft; 15, reductor output wheel; 16, reductor; 17, chain; 18, horizontal spiral follower; 19, motor; 20, air blast; 21, add coal bunker; 22, add the smalls door; 23, refractory material; 24, furnace wall; 25, combustion chamber.

Operation principle of the present utility model and advantage are

1, the horizontal auger 13 of the spirality coal that will add in the coal bunker 21 is defeated in the mode of spiral rotating Deliver to and rise in the coal bunker 7, vertical helical coal hoist 9 is carried coal again in the mode that rotates and upgrades To burning in small room and the combustion chamber, because air and space allotment are rationally, cause coal to obtain enough Oxygen and fully burning.

2, because anti-the arriving of coal burnt, and the high temperature fixed carbon is on top, and the bottom preheating produces Crude gas in sulphur steam, burned by the high temperature grate, or with calcium, magnesium, the silicon of lime-ash In the synthetic new sulfate of metallization, be solidificated in the breeze, thereby reduced sulfur oxide in the combustion gas Content, reduced environmental pollution. Because coal is fully burned, heat energy obtains fully Utilization or utilization rate are very high, thereby have saved the energy.

Concrete real-time mode
