Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1, a circular fire pan structure of closed multiple air intake combustion, includes the furnace body, the furnace body includes shell 1, inner bag 2, bottom plate 3, roof 4 and sets up the grate 5 in inner bag 2, the bottom of bottom plate 3 is provided with support 6, the first ventilation hole 7 of a plurality of has been seted up between shell 1 and inner bag 2 on bottom plate 3, the bottom of inner bag 2 is provided with a plurality of second ventilation hole 8, be provided with a plurality of third ventilation hole 9 near grate 5 department circumference on inner bag 2, be provided with a plurality of fourth ventilation hole 10 near roof 4 department circumference on inner bag 2, be provided with apron 11 in lieing in inner bag 2 department on roof 4.

Preferably, the first ventilation hole 7 is a waist-shaped hole, the second ventilation hole 8 is a rectangular hole, and the third ventilation hole 9 and the fourth ventilation hole are circular holes.

Preferably, the cover plate 11 is provided with a hand buckle 12.

Preferably, the bracket 6 comprises a plurality of support blocks.

The utility model provides a circular fire basin structure of closed many times air admission burning for traditional fire basin type structure, it is good to have the leakproofness, and the wood burning is abundant, and heat output is big, and is easy and simple to handle, simple structure, advantage such as the outward appearance is pleasing to the eye.

The closed multi-air-intake combustion circular fire pan structure is specifically manufactured by the following steps: the early preparation work comprises the steps that firstly, after the fire pan inner container 2 is manufactured, the fire pan inner container and a grate are fully welded together through argon arc, the cover plate 11 and a flange are welded together in a segmented mode through argon arc welding, after the welding is finished, 2 stainless steel double-drum self-plugging rivets are used for riveting a ring and the cover plate 11 together, in the third step, the fire pan inner container 2 and a top plate 4 are welded together in a segmented mode through argon arc welding, in the fourth step, the top plate 4 and a fire pan shell 1 are fully welded together through argon arc, in the fifth step, a bottom plate 3 is placed into a fire pan shell 1 and is fully welded together through argon arc welding, in the sixth step, 3 bottom supports 6 are welded to the shell 1 and the bottom plate 3 through argon arc full welding and argon arc spot welding, in the seventh step, a circular seam on the upper portion of the outer surface of the shell 1 is polished and drawn with the top plate 4, in the eighth step, a vertical seam is welded to the surface of the shell 1, cleaning the lower circular seam of the inner surface of the inner container 2, and integrally cleaning the inner and outer surfaces of the fire pot in the ninth step.

The whole total air inlet of the structure is from a groove-shaped waist hole of a bottom plate 3 at the lower part of the fire pan, enters the inner container 2 through a rectangular groove formed in the inner container 2 and a round hole on a grate, and is used for first air inlet and first combustion supporting; the secondary air intake is that air enters the circular hole at the lower part of the inner container 2 of the fire pan through the groove-shaped waist hole of the bottom plate 3 at the lower part of the fire pan and directly enters the inner container 2, which is the secondary air intake and the secondary combustion supporting; the air is directly entered into the inner container 2 through the slot-shaped waist hole of the bottom plate 3 of the lower part of the fire pan and the round hole at the upper part of the inner container 2, and meanwhile, the outside air can enter the inner container 2 from the open part at the upper part, so that the third air intake is also combustion-supporting for the third time.

When the wood-burning fire pot is used, the cover plate 11 is opened, the wood-burning is placed into the fire pot inner container 2, the wood-burning is ignited by the ignition material, flame can be found to be bright during burning, heat output is high, ash after burning is fine and smooth, no large particles exist, and the wood-burning fire pot is convenient to use.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
