[0023] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-3 The present invention proposes a high-temperature spray gun installation mechanism, comprising: a spray gun brick 4, a connector 3, an oxygen distribution plate 2, an oxygen distribution chamber 1, and a spray gun connector 5 for connecting a spray gun 7.

[0025] The oxygen distribution chamber 1 has a hollow frustum structure. A fifth through hole 11 for the spray gun 7 to pass through is opened in the middle of the small end of the oxygen distribution chamber 1, and the large end of the oxygen distribution chamber 1 is open. An oxygen inlet is also opened on the side wall of the oxygen distribution chamber 1. The spray gun connector 5 is detachably installed in the fifth through hole 11.

[0026] The middle part of the connector 3 is provided with an embedded through groove that runs through it along its axis, and the connector 3 is detachably and fixedly connected to the large end of the oxygen distribution chamber 1.

[0027] The oxygen distribution plate 2 is sandwiched between the connecting plate and the large end of the oxygen distribution chamber 1. The oxygen distribution plate 2 has a third through hole 21 for the spray gun 7 to pass through and a plurality of fourth through holes 22 arranged circumferentially along the third through hole 21.

[0028] The spray gun brick 4 has a first through hole 44 extending through its axial direction in the middle. The spray gun brick 4 includes a first connecting section 41 and a second connecting section 42 connected in sequence along its axial direction. The outer diameter of the first connecting section 41 is larger than that of the second connecting section 42, and the second connecting section 42 matches the embedded through groove.

[0029] The second connecting segment 42 is embedded in the embedded through groove, and the end of the second connecting segment 42 facing away from the first connecting segment 41 passes through the embedded through groove and abuts against the oxygen distribution plate 2. The fourth through hole 22 and the third through hole 21 are both located within the coverage area of ​​the first through hole 44, that is, the fourth through hole 22 and the third through hole 21 are both connected to the first through hole 44.

[0030] In a specific implementation of the present invention, the spray gun 7 is installed in the spray gun connector 5. The spray gun 7 passes through the spray gun connector 5, the fifth through hole 11, the third through hole 21 in sequence and extends into the first through hole 44. Oxygen is sent from the oxygen inlet, the hollow structure of the oxygen distribution chamber 1, and the third through hole 21 into the first through hole 44, thereby ensuring the combustion effect of the spray gun 7 during combustion.

[0031] This invention connects the spray gun 7 via the spray gun connector 5, facilitating easy replacement of the spray gun 7 as needed to ensure the furnace meets usage requirements at different stages, such as kiln firing, trial production, and normal glass melting. The fifth through hole 11, the hollow structure of the oxygen distribution chamber 1, the third through hole 21, and the first through hole 44 are connected to form a channel for inserting the spray gun 7. The spray gun 7 is inserted into this channel via the spray gun connector 5. The oxygen inlet, the hollow structure of the oxygen distribution chamber 1, the gap between the third through hole 21 and the spray gun 7, or the gap between the fourth through hole 22 and the first through hole 44 and the spray gun 7 are connected to form an inner annular oxygen channel. This ensures oxygen surrounds the nozzle of the spray gun 7, thereby guaranteeing the combustion effect of the oxygen and ensuring the usability of the glass furnace.

[0032] In this embodiment, the cross-section of the outer diameter of the spray gun brick 4 is circular.

[0033] In another embodiment, the outer diameter of the spray gun brick 4 has a square cross-section. That is, the frustum section 43 has a quadrangular frustum structure.

[0034] In one specific embodiment, the connector 3 is detachably fixed to the large end of the oxygen distribution chamber 1 via a flange. The oxygen distribution plate is provided with through holes for bolts for flange connection to pass through.

[0035] like Figures 1-5 As shown, in this embodiment, the spray gun brick 4 further includes a frustum section 43 connected to one end of the second connecting section 42 away from the first connecting section 41 in its axial direction. The maximum outer diameter of the frustum section 43 is less than or equal to the outer diameter of the second connecting section 42, and the outer diameter of the frustum section 43 gradually decreases in the direction away from the second connecting section 42.

[0036] The second connecting section 42 is embedded in the through groove, and the frustum section 43 passes through the through groove and abuts against the oxygen distribution plate 2. An air chamber is formed between the side wall of the frustum section 43 and the inner wall of the through groove. Multiple second through holes 45 are provided on the side wall of the frustum section 43, which are axially penetrating along the spray gun brick 4. The second through holes 45 are connected to the air chamber. The oxygen distribution plate 2 is also provided with a sixth through hole 23 that is connected to the air chamber.

[0037] With this configuration, the sixth through hole 23, the gas chamber, and the second through hole 45 are connected to form an outer ring oxygen channel, which allows oxygen to be introduced into the end of the spray gun brick 4 facing away from the oxygen distribution plate 2. The oxygen can directly reach the head of the spray gun 7. Through the cooperation of the outer ring oxygen channel and the inner ring oxygen channel, it is ensured that the nozzle of the spray gun 7 on the spray gun brick 4 extending into the first through hole 44 is surrounded by two layers of oxygen, thereby ensuring complete combustion and meeting the production requirements of the high-temperature furnace.

[0038] In this embodiment, multiple second through holes are spaced apart and evenly arranged around the first through hole 44 to ensure that oxygen is evenly delivered to the end of the spray gun brick 4 facing away from the oxygen distribution plate 2, thereby ensuring the combustion effect of the spray gun 7 extending into the first through hole 44.

[0039] In a further embodiment, the fourth through holes 22 are arranged circumferentially and evenly along the third through holes 21 to ensure that oxygen enters the first through hole 44 evenly, thereby ensuring the combustion effect of the spray gun 7 extending into the first through hole 44.

[0040] In a further embodiment, the fourth through hole 22 is an arc-shaped through hole, and the center of the arc-shaped through hole coincides with the center of the third through hole 21. Compared with a circular through hole, this maximizes the connection area between the hollow structure of the oxygen distribution chamber 1 and the first through hole 44 within the limited contact area between the frustum section 43 and the oxygen distribution plate 2, thereby increasing the ventilation volume of the inner ring oxygen channel.

[0041] In a further embodiment, the diameter of the end of the first through hole 44 facing away from the oxygen distribution plate 2 gradually increases in the direction away from the oxygen distribution plate 2, so as to increase the contact area between the nozzle of the spray gun 7 and the oxygen introduced into the inner ring oxygen channel and the outer ring oxygen channel, thereby ensuring the combustion effect.

[0042] like Figure 6 As shown, the present invention also proposes a glass furnace, including a furnace body, with multiple mounting holes symmetrically opened on the rib bricks 6 on both sides of the furnace body, and a high-temperature spray gun mounting mechanism for a glass furnace as described in any of the above claims inserted into each mounting hole, and a spray gun 7 mounted on each high-temperature spray gun mounting mechanism for a glass furnace.

[0043] In this embodiment, by detachably and symmetrically distributing the spray guns 7 on the breast wall bricks on both sides of the furnace body, sufficient heat can be provided as needed to meet the production requirements of the glass furnace.

[0044] Specifically, the number of mounting holes, high-temperature spray gun mounting mechanisms, and spray guns 7 is arranged according to the size of the furnace. In this embodiment, the spray gun 7 is a natural gas spray gun 7.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
