Description

Box-shaped gas furnace core of external combustion type concave cover plate

Technical Field

The utility model relates to a gas furnace core, in particular to a box-shaped gas furnace core of an external combustion type concave cover plate, 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 box-shaped gas furnace core of an external combustion type concave cover plate which is one of a series of furnace cores.

The utility model adopts the technical proposal that: the utility model provides a box-shaped gas furnace core of outer burning formula concave cover board, by the furnace core body, the burner port, gas connecting pipe and combustion-supporting wind gap constitute, the furnace core body is the long box-shaped structure who has the circular end of concave cover board for making by sheet metal, the burner port comprises a plurality of on the preceding box wall of furnace core body and the circular end box wall of distribution, the gas connecting pipe is formed and is divided into link and cup joints the end for the metal tube structure of two forms of bending, the rear end of link is connected respectively in the both sides of furnace core body rear box wall, cup joint the end and be the port of suit gas source pipeline and extend to the furnace core body with the long-range direction, the end of cup joint end still has the division board and is connected with the gas nozzle on the division board, combustion-supporting wind gap is for being connected with the through mouth of insect-proof net and by distributing each two of.

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 perspective view of the present invention;

fig. 2 is a schematic side sectional structure of the present invention.

In the figure, the furnace core comprises a furnace core body 1, a furnace core body 2, combustion holes 3, a gas connecting pipe 4, a combustion-supporting air port 5, a connecting end 6, a sleeving end 7, a gas nozzle 8 and an insect-proof net.

Detailed Description

In the embodiment of fig. 1, the box-shaped gas furnace core of the external combustion concave cover plate comprises a furnace core body 1, combustion holes 2, gas connecting pipe 3 and combustion-supporting wind gap 4 constitute, stove core body 1 is the long box-like structure who has the circular end of concave type apron for making by sheet metal, burner port 2 comprises a plurality of on the preceding box wall of stove core body 1 and circular end box wall of distribution, gas connecting pipe 3 is for forming and being divided into link 5 and cup joint end 6 by the tubular metal structure of two forms of bending, the both sides of box wall behind stove core body 1 are connected respectively to the rear end of link 5, cup joint end 6 is the port of suit gas source pipeline and extends to stove core body 1 with the long-range direction is straight, the end of cup joint end 6 is connected with gas nozzle 7 on division board and the division board in addition, combustion-supporting wind gap 4 is for being connected with the through mouth of insect-proof net 8 and by distributing each two of 3 ends 6 both sides of holding of gas connecting pipe.

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 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, the negative pressure region plays adsorption to the air outside the combustion-supporting wind gap, the air flows into the furnace core chamber from the combustion-supporting wind gap and fully mixes with the gas, both reached the combustion-supporting effect of soft beautiful flame, prevent again that the gas from leaking from the combustion-supporting wind gap.

Example 2: this outer concave type apron of box-like gas furnace core adaptation of burning formula is in the powerful outdoor heating oven of oval or dysmorphism, the gas is jetted out by the gas nozzle 8 of 1 both sides of furnace core body after mixing with the combustion-supporting wind that 4 combustion-supporting wind gaps got into, the mouth of pipe of 3 links of gas connecting pipe 5 spouts the inner chamber of 1 boxes of furnace core body, some firearm are installed outside the box body of furnace core body 1 and are lighted the gas that overflows by burner orifice 2, because of there is not the combustion-supporting of outside air in the furnace core body 1, the gas can't form the outer burning formula form at the inner chamber burning of 1 boxes of furnace core body. Firstly, the gas connecting pipes 3 are respectively clamped to the clamps of the furnace body, then the gas source pipeline is respectively connected to the sleeve joint ends 6 of the two gas connecting pipes 3 after passing through the gas switch, and finally the positioning igniter is connected and adjusted, and an oval or special-shaped external combustion type high-power outdoor heating and barbecue gas furnace can be used.
