Abstract

The utility model relates to a water seal coal-firing heating stove which is composed of a stove cover, a water tank, a stove body and a water pond, wherein an annular water tank is arranged at the top of a stove body, and a labyrinth-shaped flange is arranged below the stove cover. The utility model overcomes the disadvantages that an ordinary coal-firing heating stove needs to be added with coal by many times, the coal consumption is high, the smoke and the dust are much, the environment is polluted, etc. The utility model utilizes a water seal stove roof to cause the smoke and the dust not to drain into the space, so slag falling into the water of the water pond below a stove chamber can generate water steam to enter the stove chamber to assist combustion. The water seal coal-firing heating stove is widely used for industry of forging, hot rolling, quenching, smoldering fire, etc.

Description

Water sealed coal heating stove

The utility model relates to the heating field of industries such as forging, hot rolling, specifically a kind of water seal coal-fired furnace.

At present, other coal-fired furnace utilizes common open architecture, and its shortcoming is: seal unreasonablely, fuel combustion is insufficient, and the consumption coal is many, and flue dust is big, and contaminated environment needs repeatedly stoking, has increased working strength of workers.

The purpose of this utility model is: overcome the shortcoming of other coal furnace, design a kind of heating furnace by the water seal furnace roof, it can make full combustion of fuel, and flue dust does not directly enter the space.

The technical solution of the utility model is: a kind of water seal coal-fired furnace is to be made of the pond under body of heater, bell, tank and the body of heater.Its special character is: bell is hollow can adorn water, and bell has a steam siphunculus to be communicated with an air channel, and the water in the bell is subjected to thermogenetic water vapour, enters the air channel one time by the steam siphunculus, and it is combustion-supporting to enter burner hearth with the wind.Annular water tank is arranged at the body of heater top, can be filled with water, and close palace shape flange is arranged under the bell, and in the time of above bell covers body of heater, flange inserts in the tank water on the body of heater, and with bottom of gullet certain distance is arranged, and makes about two parts water of tank form siphon.The sealing furnace roof must not rush down furnace gas outward, and the inboard water generation water vapour that is heated enters the combustion chamber from the slit between bell and inboard wall of cistern and plays combustion-supporting effect in the tank.Lou slag pipe is housed under the combustion chamber, and slag falls into the pond by this pipe, avoids flue dust to dash, and its waste heat is emitted in water, form water vapour enter burner hearth in manage can be combustion-supporting.

The utility model is at the main body furnace upper end, and fire and smoke exit of design below the tank is sent fiery cigarette into heating clamber, and raw material are heated.For making full combustion of fuel, and in the middle of fire and smoke exit, increase a secondary air road, combustion-supporting temperature raising.

Owing to adopt above-mentioned technical scheme, can realize a kind of coal-fired province, the water seal coal-fired furnace that smoke contamination is little.

Below in conjunction with accompanying drawing embodiment, further describe this reality is novel;

Fig. 1 is a schematic diagram of the present utility model, and the accompanying drawing that makes an abstract.

Fig. 2 is a front view of the present utility model.

Fig. 3 is a bottom of the present utility model auxiliary view.

Slag pipe 3. pedestals 4. fire bars are leaked in 1. ponds 2. among the figure

5. outer steel plate 7. insulation materials 8. secondary air ducts of burner hearth 6. bodies of heater

9. 21. air channels of 19. slag notches, 20. pond covers, 16. steam siphunculus 17. tank inner edges, 18. combustion chamber, 10. tanks, 11. discharge outlet 12. bells, 13. bell water tank 14. pulleys, 15. filler, flame road, 22. heating gates, 23. heating clambers, 24. chimneys, 25. flue A, 26 flue B, 28. cinder pockets

As shown in Figure 1, bell 12, bell water tank 13 cover on tank 10, withstand bell 12 by tank inner edge 17, and bell 12 flanges insert the inside of tank 10, play face closure on the body of heater.When tank 10 is heated the generation water vapour, enter combustion chamber 18 by the slit in the middle of tank inner edge 17 and the bell 12, play combustion-supporting effect.Filler 15 is arranged on the bell 12, and discharge outlet 11 during water generates water vapour that bell 12 is heated inner, by steam siphunculus 16, enters and once adds air channel 21, plays combustion-supporting effect, and pulley 14 link bells 12 during coal, are sling bell 12.Slag notch 19 is used to remove burner hearth 5 slags and uses; During cleaning pond 1, open pond cover 20.Burner hearth 5 is built into by the outer steel plate 6 of refractory brick, insulation material 7 or body of heater, is placed on the concrete pedestal 3, has 1 the inside, a pond that water is arranged below the concrete pedestal 3, Yi Bian there is pond cover 20 to be used to slag tap on pond 1; Leak slag pipe 2 pipes and insert 1 water the inside, pond, play sealing process, can not contaminated air through slag, ashes that fire bars 4 falls.

As shown in Figure 2, heating clamber 23 is directly to be entered by flame road 9; Improve temperature for fully burning, the 9 middle secondary air ducts 8 that increase in the flame road.Workpiece enters heating clamber 23 through heating gate 22, and flue B26 or flue A25 send the cigarette of heating clamber 23 into chimney 24.

As shown in Figure 3, water is equipped with in cinder pocket 27 the insides, is as slowing down cigarette speed, precipitation lime-ash.
