Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined to clearly and completely describe the technical solutions of the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

An outdoor smokeless furnace comprises a shell body 1, wherein a furnace core 2 is detachably arranged in the shell body 1, a fire collar 4 is detachably arranged at the upper end of the shell body 1, the shell body 1 is in a cylindrical shape which is through from top to bottom, the shell body 1 comprises a ventilation part 11 arranged at the bottom end, a plurality of ventilation holes 12 are formed in the ventilation part 11, a heat preservation part 13 is arranged at the upper end of the ventilation part 11, a support frame 15 is arranged inside the heat preservation part 13, and a flue gas backflow part 14 is arranged at the upper end of the heat preservation part 13; the furnace core 2 is in a cylindrical shape with an opening at the upper end, the furnace core 2 is placed on the support frame 15, the circumferential array of the periphery of the lower end of the furnace core 2 is punched inwards and turned over to form a ventilation mechanism, and the upper end of the ventilation mechanism is detachably provided with a secondary combustion net 3; the fire collar 4 is adapted to the open end of the outer shell 1, and the inner diameter of the fire collar 4 is smaller than that of the furnace core 2.

The main principle of the smokeless furnace is that coal is combusted at low temperature, namely about 150 ℃, so as to release carbon monoxide, and then the carbon monoxide is combusted in high temperature environment to generate carbon dioxide, so that the generation of smoke is reduced. The utility model discloses in, separate stove core 2 for one-level burning chamber and second grade burning chamber by second grade burning net 3, the low oxygen low temperature burning is carried out to 2 inside bottoms of stove core, and the CO of formation rises to the high temperature burning on the second grade burning net 3 automatically, has reduced the production of flue gas, has realized smokeless burning when being as outdoor view radiator, has reduced the pollution.

Wherein, because the bottom of shell body 1 sets up ventilation portion 11, has seted up a plurality of scavenge ports 12 on ventilation portion 11, when the external world has wind or artifical oxygenating, fresh air gets into inside from the bottom of shell body 1. If the bottom end of the furnace core 2 is designed to be a net shape or other air-permeable shapes, a large amount of coal slag is left on the ground after long-time combustion, the coal slag is difficult to clean and the aesthetic degree of the landscape is damaged, and if no communication is provided, air is difficult to enter the furnace core 2. As a further improvement, referring to fig. 2 to 3, the ventilation mechanism includes a plurality of ventilation holes 21, and the upper ends of the ventilation holes 21 are folded inwards to form spoilers 22. As a further improvement, the ventilation mechanism further comprises a plurality of turbulent flow holes 23 arranged above the ventilation holes 21, the upper ends of the turbulent flow holes 23 are turned inwards to form an object placing plate 24, and the secondary combustion net 3 is placed on the object placing plate 24. When fresh air enters the outer shell 1, the fresh air is filled between the furnace core 2 and the outer shell 1, carbon monoxide generated by combustion in the furnace core 2 rises to contact with the spoiler 22 to form vortex near the spoiler 22, and external supplementary air is sucked to supplement air for secondary combustion.

As a further improvement, the inner wall of the outer shell 1 is coated with a PE fire retardant coating.

The inner diameter of the upper end of the accelerating part 43 is smaller than that of the lower end, so that the airflow is accelerated when passing through the accelerating part, and carbon monoxide which is not completely combusted by secondary combustion is accelerated and discharged along the accelerating part 43, thereby avoiding the smoke from being condensed near a furnace mouth.

The distance between the outer wall of the furnace core 2 and the inner wall of the outer shell 1 is 3-5 cm.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
