Description

Technical Field

[0001] This utility model relates to the field of kiln cooling technology, specifically to a glass kiln cooling structure. Background Technology

[0002] In various glass production processes, the glass furnace is the core of the glass production equipment. The glass furnace provides heat for the raw materials used in glass production, causing them to melt into molten glass. However, due to the high melting point of glass raw materials, the furnace walls operate at high temperatures for extended periods, making them the weakest point of the furnace, especially at the three-phase interface of the raw materials near the liquid level of the molten glass.

[0003] The description of a glass furnace wall cooling device (publication number CN203429038U) mentions that "the breast wall is set above the breast wall support plate, the lower gap filler is located in the gap formed between the breast wall and the pool wall, and it also includes a baffle plate and a duct. One side of the baffle plate is fixedly connected to the breast wall support plate, and the other side of the baffle plate is fixedly connected to the pool wall. The outlet of the duct points to any one of the baffle plate, the pool wall, or the breast wall support plate." However, the heat dissipation area of ​​the glass furnace in the prior art is small, and the heat dissipation is uneven. The increased heat dissipation of the furnace may disrupt the temperature balance inside and outside the furnace, making the furnace prone to cracking. The molten glass will aggravate the erosion of the cracked areas of the furnace wall, affecting the service life of the furnace. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a cooling structure for glass furnaces is provided to address the problems of small heat dissipation area, uneven heat dissipation, and potential disruption of temperature balance inside and outside the furnace due to increased heat dissipation. This leads to a higher incidence of furnace cracks, and the molten glass exacerbates the erosion of the furnace wall at cracked areas, thus affecting the service life of the furnace.

[0005] To achieve the above objectives, a cooling structure for a glass furnace is provided, comprising a glass furnace, a left heat transfer aluminum-copper plate, and a right heat transfer aluminum-copper plate. The glass furnace has a base at its bottom and a top seat at its top, with a flue gas channel at its center. Side cooling chambers are provided on both the left and right sides of the glass furnace, and upper cooling chambers are provided on both the left and right sides of the top seat. The left and right heat transfer aluminum-copper plates are respectively installed between the side cooling chambers on the left and right sides and the upper cooling chamber on the upper side. Inner glass plates are provided on the inner surfaces of both the left and right heat transfer aluminum-copper plates.

[0006] Furthermore, the glass furnace is provided with external electrode bricks on its outer side, and a furnace cavity is provided in the middle of the glass furnace. A lower support is provided at the bottom of the furnace cavity, and an ash hopper is supported on the lower support. A filter screen plate is mounted on the upper end of the ash hopper, and the ash hopper is a detachable structure.

[0007] Furthermore, the left and right side walls of the furnace cavity are equipped with placement racks, and a set of furnace doors are hinged to the left and right sides of the front port of the furnace cavity. The furnace doors are equipped with an upper observation window, a handle and a lower observation window, and a monitoring and control interface is provided on the lower left side of the front side of the glass furnace.

[0008] Furthermore, the upper side of the left heat transfer aluminum-copper plate is provided with an upper heat dissipation fin group, and the left side of the left heat transfer aluminum-copper plate is provided with a side heat dissipation fin group. Multiple sets of front cooling air ducts pass through the upper heat dissipation fin group and the side heat dissipation fin group. A thermocouple differential pressure gauge is installed in the upper set of front cooling air ducts. A connecting line connects the thermocouple differential pressure gauge to the monitoring and control interface. At the same time, the left heat transfer aluminum-copper plate and the right heat transfer aluminum-copper plate are symmetrical about the center line of the glass furnace.

[0009] Furthermore, the front end of the front cooling air duct is provided with a front air inlet, and a front turbine fan is installed in the front part of the front cooling air duct, and a rear air outlet is provided at the rear end of the front cooling air duct.

[0010] Furthermore, the glass furnace is provided with side ventilation ducts on both the left and right sides, and a certain part of the side ventilation duct leads into the side cooling chamber. An electromagnetic control valve is installed at the rear of the side ventilation duct, and a cooling fan is installed at the front of the side ventilation duct.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model facilitates the filtering of waste residue and dust generated during the operation of the glass kiln through the filter screen plate, and the ash hopper is easy to enter and exit the lower space inside the glass kiln, making it more convenient and time-saving to use.

[0013] 2. The placement rack in this utility model facilitates the placement of the products to be fired, and the furnace door is designed to be easily opened by flipping it over, and also allows for observation of the firing process through the upper and lower observation windows.

[0014] 3. This utility model utilizes left and right heat transfer aluminum-copper plates to transfer heat to the outer direction. The right heat transfer aluminum-copper plate has the same structure as the left heat transfer aluminum-copper plate, which facilitates the use of the front cooling air duct for alternating hot and cold air inside, which helps to achieve rapid air cooling. At the same time, the side ventilation duct is used for auxiliary ventilation and heat dissipation, which accelerates the cooling effect and cools the gap between the bottom of the electrode brick and the pool wall brick and the pool wall brick, reducing kiln cracks and improving the safety of the glass substrate kiln.
