Description

Technical Field

[0001] The utility model relates to the technical field of fierce fire stoves, in particular to an atmospheric low-pressure gas fierce fire stove. Background Art

[0002] Atmospheric low-pressure gas-fired furnace is a heating device that uses low-pressure gas for combustion. The gas is usually natural gas or liquefied petroleum gas that has its pressure reduced to a lower level through a pressure regulating valve. Compared with high-pressure gas systems, atmospheric low-pressure gas-fired furnaces use safer and more economical low-pressure gas. This furnace supplies a mixture of gas and air to the combustion chamber, and then ignites the mixture when ignited, thereby generating a high-temperature, high-pressure combustion flame. It is widely used in industrial production areas such as burning piles, boilers, and other equipment that requires high-temperature energy.

[0003] A Chinese patent discloses a low-pressure self-priming high-performance fierce fire stove (authorization announcement number CN220083063U). The patented technology includes a stove plate for placing pots, a stove body located under the stove plate, a gas pipeline connected to the stove body, an ignition needle and a controller; the stove body includes a stove body connected to the gas pipeline, and multiple gas heads installed on the stove body; an upper adjustment plate and a lower adjustment plate are installed above the stove body through adjustment bolts, and the distance between the upper adjustment plate and the lower adjustment plate is adjustable, and a gas mixing tube and a fire cap installed on the gas mixing tube are installed directly above the gas head, and the gas mixing tube is installed between the upper adjustment plate and the lower adjustment plate; the gas head and the gas mixing tube leave a distance for self-priming. The low-pressure self-priming high-performance fierce fire stove disclosed by the utility model makes the stove more convenient to use through the self-priming mechanism, and can adjust the required firepower, maximize the use of energy combustion, and is simpler, more convenient, safer and more energy-saving.

[0004] This patented technology makes rational use of energy through adjustable firepower when in use, but there are still some shortcomings when in use. The pot rack used in conjunction with the fierce fire stove can only provide a placement, and the support for the pot is unstable. The pot may easily slip due to collision, causing scalding or spilling hot oil and other dangerous situations. It also limits the types and sizes of pots that can be used. Therefore, those skilled in the art provide an atmospheric low-pressure gas fierce fire stove to solve the problems raised in the above background technology. Utility Model Content

[0039] Example 1

[0040] See also Figure 1-Figure 4 As shown, this embodiment is an atmospheric low-pressure gas-fired fierce fire stove, comprising a fierce fire stove body 100,

[0041] The support structure 200 includes support claws 201 distributed in a circular array above the fierce fire stove body 100, bearing brackets 202 fixed to the front and rear sides of the support claws 201, a rotating shaft 203 located at the lower end of the support claws 201 and rotatably mounted inside the bearing bracket 202, a torsion spring 204 sleeved on the outer side of the rotating shaft 203, a support ring 210 sleeved on the outer side of the support claws 201, threaded sleeves 209 symmetrically distributed at the upper end of the fierce fire stove body 100, and a screw 208 rotatably inserted inside the threaded sleeve 209;

[0042] A base 101 is provided at the lower end of the fierce fire stove body 100, and one end of the gas pipe 301 is located inside the base 101;

[0043] The two ends of the torsion spring 204 are respectively connected to the bearing bracket 202 and the supporting claw 201, and the supporting claw 201 is internally rotatably installed with rollers 205 distributed at equal distances;

[0044] The lower end of the support ring 210 is embedded with a symmetrically distributed rotating seat 206, the upper end of the screw 208 is rotatably inserted into the rotating seat 206, and the outer wall of the screw 208 is sleeved with a torsion block 207;

[0045] Use the fierce fire stove body 100;

[0046] The pot is placed on the supporting claw 201, and the extrusion force of the boiler acts on the supporting claw 201, and then acts on the torsion spring 204. The supporting claw 201 rotates with the rotating shaft 203 as the axis, and the supporting claw 201 expands outward at the same time and covers the outside of the pot, thereby avoiding the problem that the pot rack tightly supports the bottom of the pot and the support stability is poor.
