The utility model discloses the purpose and solve its main technical problem and adopt following technical scheme to realize:

the utility model discloses an energy-conserving coal stove circulation return air wick, including outer bucket of wick, upper cover, the interior bucket of wick, flame retardant coating B, its characterized in that: a fire-resistant layer A is arranged between the inner furnace core barrel and the fire-resistant layer B, a secondary circulation combustion device is arranged on the fire-resistant layer A and the fire-resistant layer B, the inner furnace core barrel is connected with a bottom ring, the bottom ring is connected with an outer furnace core barrel, a secondary circulation air inlet is designed on the outer furnace core barrel, the outer furnace core barrel is connected with an upper cover, the upper cover is connected on the secondary circulation combustion device, and the fire-resistant layer A and the fire-resistant layer B are placed on the bottom ring.

The upper part of the upper cover is an arc shape with a hollow inner part, and the lower part of the upper cover is a circular ring shape.

And a plurality of holes are formed in the secondary circulating combustion device.

The upper part of the secondary circulation combustion device is in a conical cylinder shape, and the lower part of the secondary circulation combustion device is in a circular ring shape.

And a secondary circulating air inlet is formed in the outer barrel of the furnace core.

Compared with the prior art, the utility model obvious advantage and beneficial effect have. According to the above technical scheme, the utility model discloses a be provided with flame retardant coating A between bucket, flame retardant coating B in the wick, be provided with the secondary cycle burner above flame retardant coating A, the flame retardant coating B, barrel attach the foundation ring in the wick, the outer bucket of wick is connected to the foundation ring, and the upper cover is connected to the outer bucket of wick, and the upper cover is connected on the secondary cycle burner, has placed flame retardant coating A, flame retardant coating B above the foundation ring. Because the fuel is burnt in the fire-resistant layer B, the fire-resistant layer A and the fire-resistant layer B effectively protect the outer barrel and the inner barrel of the furnace core from being burnt out, and the service life of the furnace core is prolonged. Meanwhile, after the insufficiently combusted black smoke is mixed with oxygen in the holes 4 communicated with the secondary circulating air inlet 6, secondary combustion is formed at the secondary circulating combustion device 3, so that fuel particles in the insufficiently combusted black smoke are combusted again, and the purposes of small black smoke, large flame, low energy consumption, high energy utilization rate, high heat transfer efficiency and sufficient combustion are achieved.
