Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a special burner for industrial gas kilns. Background Art

[0002] Burner is a general term for devices that spray fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application fields. They are mostly made of corrosion-resistant and high-temperature resistant materials such as stainless steel or metal titanium. The function of the burner is to atomize the sample through flame combustion. The atomized test solution enters the burner and, under the action of flame temperature and flame atmosphere, undergoes processes such as drying, melting, evaporation, and dissociation to produce a large number of ground state atoms, as well as some excited state atoms, ions, and molecules. A well-designed burner should have high atomization efficiency, low noise, and stable flame to ensure high absorption sensitivity and measurement precision. Slit burners are often used to produce atomic vapor in atomic absorption spectrometry. The length and width of the burner gap vary depending on the type of gas and combustion-supporting gas used. Generally, the applicable gas and combustion-supporting gas are marked on the burner.

[0003] When an industrial gas kiln is in operation, a burner is generally used. Although the existing burners can emit flames of different degrees, since the industrial gas kiln needs to constantly change the flame injection position to make the internal material melting more uniform, most of the existing burners are fixed and not easy to move, resulting in uneven melting of the internal material of the industrial gas kiln, requiring multiple burners for melting, thereby increasing energy loss and being inconvenient to use. Therefore, a special burner for industrial gas kilns is proposed to solve the above-mentioned problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 In this embodiment, a burner dedicated to an industrial gas kiln includes a burner body 1, a mounting box 2, a vehicle body 3 and an extension nozzle 4, and a reciprocating moving mechanism is arranged outside the vehicle body 3;

[0023] The reciprocating moving mechanism includes a driving motor 5 fixedly mounted on the back of the installation box 2, the output shaft of the driving motor 5 is fixedly connected with a screw rod 6, the outer surface of the screw rod 6 is threadedly sleeved with a threaded sleeve 7, the interior of the installation box 2 is fixedly connected with a sleeve rod 8, the outer surface of the sleeve rod 8 is sleeved with a sliding sleeve 9, the tops of the threaded sleeve 7 and the sliding sleeve 9 are fixedly connected with a connecting rod 10, the top of the connecting rod 10 is fixedly connected with a moving platform 11, and the bottom of the burner body 1 is fixedly connected with the top of the moving platform 11. By setting the reciprocating moving mechanism, when the front end of the spray gun of the burner body 1 is inserted into the interior of the industrial gas kiln and sprays flames, the staff only needs to start the driving motor 5 to drive the screw rod 6 to rotate, so that the threaded sleeve 7 and the sliding sleeve 9 drive the moving platform 11 through the connecting rod 10, and reciprocate in a front-to-back state on the top of the installation box 2, thereby constantly changing the flame spraying position of the burner body 1, so that the internal material is melted more evenly, and there is no need for multiple burners to carry out melting, which effectively reduces energy loss and is more conducive to use.

[0024] Among them, a protective cover 12 is arranged on the outside of the burner body 1, and a heat insulation pad 13 for heat insulation is fixedly connected to the inside of the protective cover 12, and through holes 16 for pipeline connection are opened on the front, back and sides of the protective cover 12, and buckles 14 are fixedly connected to the front and back of the mobile platform 11, and matching blocks 15 are fixedly connected to the front and back of the protective cover 12.
