Description

Technical Field

[0001] The invention relates to the technical field of glass kilns, and in particular to a small furnace inclined arch structure of a glass kiln. Background Art

[0002] The small furnace of the glass kiln is a flame burner. The two airflows of fuel gas and air are first mixed and pre-burned locally in the small furnace, and then sprayed into the kiln from the outlet of the small furnace for complete combustion. In order to ensure that the flame has good stability and a large coverage area, the flow rate and spray angle of both fuel gas and air need to be adjusted to change the spray speed and direction of the flame.

[0003] At present, the angle of the inclined arch structure of the traditional glass kiln cannot be changed after it is fixed. When the length and size of the flame need to be adjusted, it can only be done by adjusting the angle and flow rate of the fuel spray gun. However, because the fuel spray gun is only used to provide fuel gas, the angle and flow rate of the air cannot be actively adjusted, so the adjustment range of the flame is very small. At the same time, different fuels (such as natural gas and heavy oil) have different requirements for the spray angles of fuel gas and air. It is often difficult for the same kiln type to simultaneously meet the requirements for the air angle when switching between different fuels. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a glass furnace small furnace inclined arch structure capable of realizing air angle adjustment.

[0005] The present invention adopts the following technical solution:

[0006] The present invention provides a glass kiln small furnace inclined arch structure, comprising a plurality of arch bricks, the plurality of arch bricks are abutted against each other to form an arch brick combination distributed in a rectangular shape on a horizontal plane and seal the top opening of the glass kiln small furnace, and each arch brick is vertically hung on a beam on the top of a workshop through a set of lifting devices.

[0007] Preferably, in the longitudinal direction of the horizontal plane, the arch brick assembly is tightly clamped between the small furnace flat arch and the melting breast wall; in the transverse direction of the horizontal plane, the arch brick assembly is tightened by top screws arranged at intervals on both sides.

[0008] Preferably, the arch brick combination comprises more than 3 arch bricks arranged close to each other in the longitudinal direction of the horizontal plane, and the arch brick combination comprises more than 5 arch bricks (an odd number of which) arranged close to each other in the transverse direction of the horizontal plane.

[0009] Preferably, the lifting device includes an electric hoist and a hanging fixture, the electric hoist is fixed on the beam at the top of the workshop, and the hanging fixture is mounted on the connecting end on the top of the arch brick and connected to the hook end of the electric hoist through a wire rope.

[0010] Preferably, a plurality of spare arch bricks are provided, which can be used interchangeably with the main arch bricks and are provided with top insertion gun holes for inserting fuel spray guns. The top insertion gun holes on each spare arch brick are different from those on other spare arch bricks in terms of opening angle.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The inclined arch structure of the small furnace of the glass kiln of the present invention divides the original integrated inclined arch on the top of the small furnace into multiple independently controlled individuals, so that the vertical positions of multiple arch bricks can be controlled by multiple sets of lifting devices, so that the arch brick combination can be adjusted to the required angle, and then the air introduced into the small furnace is transported to contact the arch brick combination, and the angle of the air sprayed into the kiln can be adjusted under the influence of the arch brick combination, so that the adjustment range of the flame becomes larger, ensuring that the flame has better stability and a larger coverage area, and meeting the combustion angle requirements of various fuels for combustion-supporting air.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0036] See also Figure 1The present embodiment provides a glass kiln small furnace inclined arch structure, including a plurality of arch bricks 1, the plurality of arch bricks 1 are abutted against each other to form an arch brick combination 2 distributed in a rectangular shape on a horizontal plane and block a top opening 3 of the glass kiln small furnace, and each arch brick 1 is vertically hung on a beam (not shown in the figure) on the top of the workshop through a set of lifting devices 4.

[0037] See also Figures 1 to 3 The inclined arch structure of the small furnace of the glass kiln in this embodiment divides the original integrated inclined arch on the top of the small furnace into multiple independently controlled individuals, so that the vertical positions of multiple arch bricks 1 can be controlled by multiple sets of lifting devices 4, so that the arch brick combination 2 can be adjusted to the required angle, and then the air introduced into the small furnace is transported to contact the arch brick combination 2, and the angle of the air sprayed into the kiln can be adjusted under the influence of the arch brick combination 2, so that the adjustment range of the flame becomes larger, ensuring that the flame has better stability and a larger coverage area, and meeting the combustion angle requirements of various fuels for combustion-supporting air.

[0038] Preferably, see Figure 1 and Figure 4 In the longitudinal direction of the horizontal plane, the arch brick assembly 2 is tightly clamped between the small furnace flat arch 5 and the melting breast wall 6; in the transverse direction of the horizontal plane, the arch brick assembly 2 is tightened by the top screws 7 arranged at intervals on both sides.

[0039] It should be noted that see Figure 1 , the air is introduced into the small furnace from the side where the small furnace flat arch 5 is located, and after being partially mixed with the fuel gas in the small furnace, it is sprayed into the kiln from the side where the melting breast wall 6 is located for complete combustion; when it is necessary to adjust the spray angle of the combustion-supporting air, refer to Figures 1 to 4 First, loosen the top screws 7 on both sides, and then adjust the height of each block of the brick 1 in turn through the lifting device 4 to complete the adjustment of the spray angle of the combustion air; in addition, the top screw 7 is set on the column, and the column is a structure built into the glass kiln.

[0040] Preferably, see Figure 3 and Figure 4 The arch brick combination 2 has more than three arch bricks 1 arranged close to each other in the longitudinal direction of the horizontal plane, and the arch brick combination 2 has more than five arch bricks 1 (an odd number of them) arranged close to each other in the transverse direction of the horizontal plane.

[0041] The traditional small furnace inclined arch is subjected to lateral force and the related components used for lateral fastening are difficult to replace. Therefore, it is often limited by the insufficient lateral fastening force and the length and width of the small furnace cannot be expanded as needed. However, each arch brick 1 of the present embodiment is subjected to vertical force and does not need to replace the related components used for lateral fastening, thereby breaking through the limitation of the arch span of the conventional small furnace. Therefore, the length and width of the small furnace can be increased as needed. 3, 4, 5, ... arch bricks 1 can be arranged in the longitudinal direction of the horizontal plane, and 5 or 7, 9, 11, ... arch bricks 1 can be arranged in the lateral direction of the horizontal plane to meet the demand of large-scale kilns for large small furnaces.

[0042] Preferably, see Figure 5 The lifting device 4 includes an electric hoist (not shown in the figure) and a hanging fixture 401. The electric hoist is fixed on the beam on the top of the workshop. The hanging fixture 401 is mounted on the connecting end on the top of the arch brick 1 and is connected to the hook end of the electric hoist through a wire rope 402.

[0043] In actual use, by controlling the lifting of the electric hoist, the height adjustment of the corresponding arch brick 1 can be synchronously controlled; in addition, since each arch brick 1 is connected to its own hanging fixture 401, if a certain area of ​​the small furnace is severely burned and the top inclined arch needs to be replaced in the later stage of the kiln life, the electric hoist can be controlled individually to lift a certain arch brick 1 and replace it with a new arch brick 1 on the hanging fixture 401, thereby extending the kiln life without affecting production.

[0044] Preferably, see Figure 6 and Figure 7 The inclined arch structure of the small furnace of the glass kiln in this embodiment is also equipped with a plurality of spare arch bricks 8, which can be replaced with the arch bricks 1, and the spare arch bricks 8 are provided with top insertion gun holes 801 for inserting fuel spray guns, and the top insertion gun holes 801 on each spare arch brick 8 are different from other spare arch bricks 8 in terms of opening angle.

[0045] After using the spare arch brick 8 to replace the corresponding arch brick 1, the fuel spray gun can be inserted on the spare arch brick 8 for use; at the same time, the setting of a variety of different spare arch bricks 8 also meets the multi-angle top insertion requirements of the fuel spray gun, and when the top insertion gun hole 801 is severely burned, a new spare arch brick 8 of the same type can be replaced at any time for replacement.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
