[0029] In the cooling system of the glass kiln, the burner is located at a higher position of the kiln, and the setting of its cooling assembly is inconvenient. Moreover, the cooling air volume required by the burner is not too large. If a cooling fan is set up for the burner cooling assembly alone, the equipment cost and use cost of the cooling system will be too high, increasing the production cost of the glass cover. Therefore, the present application adopts the method of guiding the cooling air from other parts to the burner cooling assembly to realize the reuse of the cooling fan, thereby reducing the equipment cost and use cost of the cooling system.

[0030] Among them, the applicant took into account that the cooling process of the burner needs to be carried out after the kiln is over-fired, which is earlier than the cooling process of the pool wall of the glass kiln and lags behind the cooling process of the kiln sill. Therefore, the applicant abandoned the pool wall cooling component closer to the burner, and combined the burner cooling component with the kiln sill cooling component to meet the cooling process requirements of the glass kiln and save equipment costs and usage costs.

[0031] Specifically, Figures 1 to 3 An embodiment of the glass furnace cooling system of the present application is conveniently illustrated.

[0032] like Figures 1 to 3 As shown, the present application discloses a glass furnace cooling system, including: a burner cooling assembly 2 and a kiln sill cooling assembly 1. The kiln sill cooling assembly 1 includes: a cooling fan 12 and a kiln sill cooling pipe 11 connected to the cooling fan 12. The burner cooling assembly 2 includes: an induced draft pipe 21 and a burner cooling pipe. The induced draft pipe 21 connects the kiln sill cooling pipe 11 and the burner cooling pipe, and guides the cooling air in the kiln sill cooling assembly 1 to the burner cooling assembly 2.

[0033] Through the above design, the present application jointly sets the burner cooling assembly 2 and the kiln sill cooling assembly 1, and draws cooling air from the kiln sill cooling assembly 1 to cool the burner, thereby reducing the number of cooling fans 12 to be set, and reducing the equipment cost and use cost of the cooling system. Moreover, since the cooling process of the kiln sill has already started at the initial stage of the operation of the glass kiln, it is carried out before the cooling process of the burner. Therefore, the working sequence of the kiln sill cooling fan 12 can fully meet the cooling requirements of the burner from a process point of view, and will not affect the original cooling process. Therefore, the embodiment of the present application is suitable for both the construction of a new glass kiln cooling system and the energy-saving transformation of an existing glass kiln cooling system.

[0034] In some embodiments of the present application, Figures 1 to 3As shown, a plurality of burners are arranged on both sides of the glass kiln, and correspondingly, the burner cooling pipe includes: a left burner cooling dry pipe 25 distributed along the left side of the glass kiln, and a right burner cooling dry pipe 24 distributed along the right side of the glass kiln. The left burner cooling dry pipe 25 and the right burner cooling dry pipe 24 are respectively extended horizontally along the length direction of the glass kiln to cool the burners on the left and right sides. Moreover, the left burner cooling dry pipe 25 and the right burner cooling dry pipe 24 are respectively connected to the burner cooling branch pipe 26 leading to each burner to transport cooling air to each corresponding burner to cool the burner.

[0035] In some embodiments of the present application, Figure 1 and Figure 2 As shown, in the burner cooling assembly 2, the induced air duct 21 is vertically arranged and used as the main duct of the burner cooling assembly 2. The kiln sill cooling duct 11 is provided with a first three-way joint (not shown), one end of which is vertically connected to the lower end of the induced air duct 21. The upper end of the induced air duct 21 is provided with a second three-way joint 23, which is a right-angle corner tee, one end of which is vertically connected to the induced air duct 21 downward, and the other two ends are respectively arranged horizontally to respectively connect the left burner cooling main duct 25 and the right burner cooling main duct 24.

[0036] Since the induced draft duct 21 is arranged vertically, the burner cooling duct and the kiln sill cooling duct 11 are connected only by two upper and lower three-way joints, so the structure is simple and the cost is low. The laying distance of the duct is short and the distribution is straight, which realizes the nearest straight line induced draft, which is beneficial to reduce the duct pressure drop generated by the induced draft process and save energy costs.

[0037] In some embodiments of the present application, Figures 1 to 3 As shown, the induced air duct 21 is provided with an induced air regulating mechanism 22 for changing the cooling air flow rate and / or pressure, so that the cooling air flow rate and / or pressure in the kiln sill cooling assembly 1 can be adjusted to a value suitable for the burner cooling assembly 2, thereby meeting the burner cooling needs. Figures 1 to 3 As shown, each burner cooling branch pipe 26 is provided with a branch regulating mechanism 27 for adjusting the air volume of each branch, so as to realize independent cooling of each burner and improve the cooling control accuracy of the burner.

[0038] In some embodiments of the present application, the burner cooling assembly 2 also includes multiple temperature detection mechanisms, each of which is installed at the position of each burner to detect the real-time temperature of each burner for monitoring by production personnel to adjust the cooling air volume.

[0039] In some embodiments of the present application, the burner cooling assembly 2 further includes a controller, which is connected to each temperature detection mechanism, each branch regulating mechanism 27 and the induced draft regulating mechanism 22. Thus, each branch regulating mechanism 27 and the induced draft regulating mechanism 22 can be linked with each temperature detection mechanism through the controller to achieve automatic feedback regulation, so as to improve the automation of the cooling system, reduce the intensity of human work, maintain the temperature cooling effect of each burner stable, and protect the safety of production equipment.

[0040] In some embodiments of the present application, the branch regulating mechanism 27 and the induced draft regulating mechanism 22 are both regulating valves, which may be manual regulating valves or automatic regulating valves (such as solenoid valves). The temperature detection mechanism may be a thermocouple.

[0041] In some embodiments of the present application, Figures 1 to 3 As shown, in the burner cooling pipes on the left and right sides, the ends of each burner cooling branch pipe 26 are connected to a bellows 28, which extends to the fire baffle of the burner, and its end faces the fire baffle to blow air to cool the fire baffle. Among them, in the preferred embodiment of the present application, the bellows 28 is a metal bellows 28, which has high high temperature resistance and mechanical properties, good heat conduction effect, stable structure, and long service life.

[0042] Combination Figures 1 to 3 The embodiment shown illustrates the process flow of the glass furnace cooling system of the present application embodiment:

[0043] When applied to the modification of an existing glass kiln, it is only necessary to connect the first three-way joint to the kiln sill cooling pipe 11 of the glass kiln to introduce the induced draft pipe 21, and use the induced draft pipe 21 as the main pipe of the burner cooling assembly 2. During production, the kiln sill cooling air is adjusted to become kiln burner cooling air with a suitable air volume through the induced draft adjustment mechanism 22, and the kiln burner cooling air is distributed to the right burner cooling main pipe 24 and the left burner cooling main pipe 25 of the kiln through the second three-way joint 23, and then enters the burner cooling branch pipes 26 on the left and right sides, and then after being adjusted by the branch adjustment mechanism 27, it is blown to the burner fire damper through the metal bellows 28, so as to achieve the effect of cooling the burner fire damper.

[0044] Based on the above glass kiln cooling system, the present application also discloses a glass kiln, which is provided with any of the above glass kiln cooling systems. The glass kiln of this embodiment realizes the reuse of the cooling fan 12 in the kiln sill cooling assembly 1 by drawing out the cold air from the kiln sill cooling pipe 11 and using it as the cold air source for the burner, thereby reducing the equipment cost and use cost of the glass kiln.

[0045] In summary, the glass kiln cooling system of the embodiment of the present application combines the burner cooling assembly with the kiln sill cooling assembly, and draws cooling air from the kiln sill cooling assembly to cool the burner, which can reduce the number of cooling fans, thereby reducing the equipment cost and use cost of the cooling system. Moreover, since in the glass kiln, the kiln sill cooling process starts at the beginning of the operation of the glass kiln, before the cooling process of the burner, the working sequence of the kiln sill cooling fan can fully meet the cooling requirements of the burner from a process point of view, and will not affect the original cooling process. Therefore, the embodiment of the present application is suitable for both the construction of a new glass kiln cooling system and the modification of an existing glass kiln cooling system.

[0046] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
