Description
Technical Field
The utility model relates to a gas furnace core, in particular to a flame-proof round box-shaped gas furnace core, which belongs to the technical field of gas furnaces.
Background
The traditional barbecue oven is a barbecue device, and is a stove for barbecue of materials such as mutton shashlik, vegetables and barbecue. The barbecue grill is carried to the field by the trolley on weekends, chats and drinks smoothly while enjoying the fun of barbecue, on one hand, the barbecue grill can fly to relieve the mental state to relieve the pungency of working at ordinary times, on the other hand, a new bright spot is newly added for urban life, and the barbecue grill is a novel leisure catering mode capable of improving the life quality of people. Barbecue ovens can be divided into charcoal, gas, electric, microwave and solar ovens, with gas and electric ovens being popular for their smoke and smoke free, non-polluting qualities. However, the electric oven is difficult to adapt to field use due to the limitation of power supply, and the electric oven is also a gas oven which is most widely applied. The basic principle of the gas barbecue oven is that gas is ignited into flame through an oven core to generate heat, and then the combustion heat is used for barbecue and decoction of materials. Along with the improvement of living standard and the continuous update of consumption concept, the shape, the structure and the function of the barbecue oven are also continuously updated along with wider adaptability, especially in European and American markets, even the barbecue oven is integrated into landscape elements, so that the barbecue oven has a brand-new conceptual structure integrating barbecue, decoction, heating and landscape, and simultaneously, various structural forms including wall hanging, fireplaces, table tables and the like are evolved due to the need of adapting to different environments and occasions. The stove core which is used as a core component is a traditional functional stove for barbecue and decoction or a modern concept stove integrating multiple functions, and the reasonable design of the structural form, the power and the combustion-supporting air-fuel ratio is very important.
Disclosure of Invention
In order to solve the technical problems of different structural forms and different power gas furnaces adapting to the furnace core, the utility model provides a flame-isolating round box-shaped gas furnace core which is one of series furnace cores.
The utility model adopts the technical proposal that: a flame-isolating round box-shaped gas furnace core comprises a furnace core body and a burner nozzle, the gas connecting pipe and the combustion-supporting tuyere are composed of a gas connecting pipe and a combustion-supporting tuyere, the furnace core body is a box body of a flat-bottom cylindrical structure made of metal materials and is in a structure of a flat-bottom inclined-edge bowl-shaped box cover, the outer edge of the box cover is smaller than the outer wall of the box body, a bowl opening of the box cover is downwards connected to the middle of the upper surface of the box body, a burner nozzle is formed by uniformly distributing a plurality of round holes on the periphery of the upper end of a round pipe of a cap-shaped structure, the gas connecting pipe is of a bent metal pipe structure and is divided into a connecting end and a sleeving end, the upper end of the connecting end is connected to the middle of the inside of the box body in an extending mode, a connector is communicated with the lower surface of the burner nozzle, the sleeving end is a port for sleeving a gas source pipeline and extends.
The utility model has the advantages that: the utility model relates to one of the furnace cores of an outdoor heating gas furnace series. Firstly, the series of gas stove cores have the characteristics of small volume, high power, soft and beautiful flame color and the like; secondly, the furnace cores of various specifications achieve the optimal proportion of a gas nozzle and a combustion-supporting air port through repeated tests in a laboratory; the furnace core of the series is designed strictly according to the principle of a Venturi tube, and outside air is adsorbed by negative pressure in a combustion-supporting air port to flow into a furnace core cavity to be fully mixed with gas, so that the combustion-supporting effect of soft and beautiful flame is achieved, and the gas is prevented from leaking from the combustion-supporting air port.
Drawings
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 is a schematic side view of the present invention.
In the figure, the furnace core comprises a furnace core body 1, a burner 2, a burner 3, a gas connecting pipe 4, a combustion-supporting air port 5, a box body 6, a box cover 7, a connecting end 8, a sleeve joint end 9 and an insect-proof net.
Detailed Description
In the embodiment of fig. 1, a flame-proof round box-shaped gas furnace core is composed of a furnace core body 1, a burner 2, a gas connecting pipe 3 and a combustion-supporting tuyere 4, wherein the furnace core body 1 is a box body 5 which is made of metal material and has a flat-bottomed cylindrical structure and a structure of a box cover 6 which is a flat-bottomed inclined-side bowl-shaped box cover 6, the outer edge of the box cover 6 is smaller than the outer wall of the box body 5, the bowl opening of the box cover 6 is connected downwards to the middle of the upper surface of the box body 5, the burner 2 is formed by uniformly distributing a plurality of round holes on the periphery of the upper end of a round pipe of a cap-shaped structure, the gas connecting pipe 3 is a bent metal pipe structure and is divided into a connecting end 7 and a socket end 8, the upper end of the connecting end 7 is connected to a middle connecting port inside the box body 5 in an extending manner and is communicated with the lower surface of the burner, the combustion-supporting tuyere 4 is a through opening connected with an insect-proof net 9 and consists of two parts which are distributed at two sides of the sleeved end 6 of the gas connecting pipe 3.
Example (b): the series of gas furnace cores comprise various specifications, and the optimal proportion of a gas nozzle and a combustion-supporting air port 4 is achieved after the furnace cores with various specifications are repeatedly tested in a laboratory; the flue gas emission of the furnace cores with various specifications is lower than the CSA certification index of 2000ppm through the flue gas test of a laboratory, and the standard of entering the European and American markets is achieved; this series of gas furnace core still because design according to the venturi principle strictly, can produce the low pressure near according to "fluid that flows at a high speed", thereby produce the venturi effect of adsorption, when the gas passes through the gas nozzle that the sectional area diminishes, produce higher velocity of flow under the effect of pressure, just form the negative pressure in the combustion-supporting wind gap 4, the negative pressure region plays the adsorption to the air outside combustion-supporting wind gap 4, the air flows into the furnace core chamber from combustion-supporting wind gap 4 and fully mixes with the gas, both reached the combustion-supporting effect of soft beautiful flame, prevent again that the gas from leaking from combustion-supporting wind gap 4.
Example 2: this round box-shaped gas furnace core of flame-proof formula adaptation is in the outdoor heating oven at the simple and easy stove bottom of no flame's circle. Firstly, the gas connecting pipe 3 is clamped to a fixture of a furnace body, then the gas source pipeline is connected to the sleeve joint end 8 of the gas connecting pipe 3 through a gas switch, and finally the positioning igniter is connected and adjusted, so that the flameless round outdoor heating and barbecue gas furnace can be used.
