[0002] The melting part of the glass melting furnace is located between the front wall and the neck of the partition equipment. Its main function is to melt the batch materials, clarify and homogenize the glass liquid. It consists of a melting zone and a clarifying zone; the upper and lower parts are divided into an upper space and a lower kiln pool. The upper space is also called the flame space, which is a flame-filled space surrounded by the front wall, the surface of the glass liquid, the large arch on the top of the kiln and the breast wall of the kiln wall; the lower pool kiln consists of a pool bottom and a pool wall. With the advancement of technology and the substantial increase in the scale of melting, more and more electric melting materials are used. For example, the main structure of the all-oxygen melting furnace is made of electric melting refractory materials. However, in the later use process, it is inevitable that the electric melting bricks will be eroded or seeped due to the excessively high breast wall temperature, and then form defects such as stones, which seriously affect the quality and safety of glass production.

[0042] The embodiments of the present application disclose a cooling structure.

[0043] See also Figures 1 to 3 , an embodiment of the cooling structure provided in the embodiments of the present application includes:

[0044] Structural body 1.

[0045] The structural body 1 is provided with a heat exchange surface that can fit the heat generating part. The shape and size of the heat exchange surface can be adaptively designed according to the shape and size of the heat generating part that needs to be cooled, and there is no specific limitation.

[0046] The structural body 1 is provided with a cooling cavity in a zigzag distribution for circulating a cooling medium so as to cool the heat generating part through the heat exchange surface.

[0047] A through hole 10 connected to the cooling cavity is provided on the heat exchange surface. The through hole 10 can be a circular hole or a long strip hole. The specific number of the through hole 10 can be changed and designed according to needs without limitation. The structural body 1 is provided with a cavity inlet 31 connected to one end of the cooling cavity and a cavity outlet 32 ​​connected to the other end of the cooling cavity.

[0048] The cooling structure designed in this application has the following beneficial effects:

[0049] 1. Attach the heat exchange surface to the desired cooling part and then introduce the cooling medium into the cooling cavity, so that the desired cooling part can be cooled in a certain area in a targeted manner; for example, when the breast wall temperature is too high and exudate causes stones and other defects, the cooling structure can be attached to the area to achieve cooling of the breast wall in the area, thereby changing the temperature gradient in the thickness direction of the breast wall bricks, reducing or delaying the exudate of the fused bricks; for another example, if the local temperature of the pool bottom is too high, the cooling structure can be attached to the hard brick part of the pool bottom to quickly cool the part.

[0050] 2. The cooling cavity is designed to be zigzag, which prolongs the contact time between the cooling medium and the heat exchange surface, helping to improve the heat exchange efficiency; moreover, the heat exchange surface is designed with a through hole 10 connected to the cooling cavity, which enables part of the cooling medium to directly contact the heat-generating part through the through hole 10, further improving the cooling effect.

[0051] The above is the first embodiment of the cooling structure, cooling device and glass melting furnace provided in the embodiment of the present application. The following is the second embodiment of the cooling structure, cooling device and glass melting furnace provided in the embodiment of the present application. For details, please refer to Figures 1 to 3 .

[0052] Based on the solution of the above embodiment 1:

[0053] Furthermore, a plurality of first partition plates 21 are provided in the structural body 1, for separating cooling channels in the structural body 1. A single first partition plate 21 can form a cooling channel with one turning portion; and a plurality of first partition plates 21 can form a cooling channel with a plurality of turning portions, so as to better realize a meandering distribution design; taking a design of a plurality of first partition plates 21 as an example, the plurality of first partition plates 21 are arranged in sequence and staggered with each other.

[0054] Furthermore, in order to allow the cooling medium coming out of the through hole 10 to fully contact the heating part, a cooling groove with the same distribution trajectory as the cooling cavity is provided on the heat exchange surface, and a groove outlet 33 connected to the cooling groove is also provided at the position where the cavity outlet 32 ​​is provided on the structural body 1. After the heat exchange surface is attached to the heating part, a relatively closed cavity can be formed between the cooling groove and the surface of the heating part to provide a certain space for the cooling medium coming out of the through hole 10, so that the cooling medium coming out can fully contact the heating part; the distribution trajectory of the cooling groove is consistent with the distribution trajectory of the cooling cavity, and a groove outlet 33 is provided, so that the cooling medium in the cooling groove also flows with the cooling medium in the cooling cavity to smoothly take away the heat and improve the cooling effect.

[0055] Furthermore, the edges of the heat exchange surface are provided with convex edges, that is, the heat exchange surface has a groove surrounded by the convex edges, and a plurality of second partition plates 22 are provided in the groove surrounded by the convex edges, which are used to separate the cooling groove on the heat exchange surface. The distribution of the second partition plates 22 is basically the same as that of the first partition plates 21. Since the cooling groove does not need to be provided with a groove inlet, its inlet is a through hole 10. Therefore, one end of the cooling groove can be relatively closed, and the other end can be designed with a groove outlet 33. Those skilled in the art can make appropriate changes based on this design, and there is no specific limitation.

[0056] Furthermore, an inlet channel 16 is provided in the structural body 1 , one end of the inlet channel 16 is connected to one end of the cooling cavity, and the other end extends out of the structural body 1 to facilitate connection with a cooling medium supply device; the cavity inlet 31 is provided on the other end of the inlet channel 16 .

[0057] Furthermore, with regard to the design of the structural body 1 , it may include a front plate 17 (not shown in the figure), a back plate 15 , an upper plate 14 , a lower plate 12 , a left plate 11 and a right plate 13 .

[0058] The upper plate 14 , the right plate 13 , the lower plate 12 and the left plate 11 are sequentially connected in a clockwise direction to form a rectangular middle frame.

[0059] The front plate 17 and the back plate 15 are arranged in parallel and are both fixed in the middle frame. A surface of the back plate 15 away from the front plate 17 forms a heat exchange surface.

[0060] Taking this design as an example, the first partition plate 21 can be arranged in the structural body 1 in parallel with the upper plate 14 or the lower plate 12. Taking two designs as examples, the two first partition plates 21 are arranged in parallel and spaced apart from the lower plate 12 to the upper plate 14, and are staggered to separate the inner cavity of the structural body 1 into a winding cooling cavity.

[0061] The peripheral edge of the front plate 17 can be connected to one side edge of the middle frame, while the peripheral wall + of the back plate 15 is connected to a position on the inner wall of the middle frame close to the other side edge to ensure that the other side edge of the middle frame can protrude from the back plate 15 to form the above-mentioned convex edge portion, so that a groove can be provided on the heat exchange surface; the second partition plate 22 located on the heat exchange surface can be an independent partition design, or formed by the first partition passing through a part of the partition on the back side, and there is no specific limitation.

[0062] As for the formation of the inlet channel 16, a third partition plate 23 parallel to the left plate 11 can be designed near the left plate 11, and the inlet channel 16 is formed between the third partition plate 23 and the left plate 11, the front plate 17, and the back plate 15. In order to allow the inlet channel 16 to extend out, the left plate 11 can be partially extended, and at the same time, the front plate 17, the back plate 15 and the third partition plate 23 can all be partially extended, and the extended parts also form the channel part where the inlet channel 16 extends out; when the inlet channel 16 is designed, one end of the first partition plate 21 near the lower plate 12 is connected to the third partition plate 23, and a cavity inlet 31 is formed between one end of the first partition plate 21 and the left plate 11, the front plate 17, and the back plate 15, and the cavity outlet 32 ​​can be opened on the upper plate 14.

[0063] The present application also discloses a cooling device, including a fan (not shown) and the cooling structure of embodiment one or embodiment two, the air outlet end of the fan is connected to the cavity inlet 31 of the cooling structure. It can be understood that the fan blows air into the cooling cavity, and the wind passing through the cooling cavity is used to take away heat to achieve heat exchange, that is, the cooling medium is cold air.

[0064] Furthermore, the air outlet of the fan is connected to the cavity inlet 31 through a flexible connecting pipe, so that the cooling structure can be flexibly installed without affecting the installation and fixation of the fan.

[0065] An air valve for adjusting the opening is also provided between the air outlet of the fan and the cavity inlet 31. The fan is a frequency conversion controlled fan, and the air valve can achieve precise adjustment of the air volume.

[0066] Furthermore, it also includes a pressure sensor and a temperature sensor.

[0067] The pressure sensor may be disposed between the fan and the cavity inlet 31 or in the cooling cavity of the cooling structure to detect the gas pressure in the cooling cavity.

[0068] There are at least two temperature sensors, at least one of which is set at the cavity inlet 31 to detect the temperature of the gas before the cooling cavity, and at least one is set at the cavity outlet 32 ​​to detect the gas problem after the cooling cavity. By setting up a pressure sensor and a temperature sensor, the wind pressure and wind temperature can be accurately monitored, so as to accurately adjust the fan power and the air valve opening based on the wind pressure and wind temperature, and achieve more precise control.

[0069] The present application also discloses a glass melting furnace, comprising a melting furnace body and a cooling device, wherein a cooling structure of the cooling device is mounted on the melting furnace body.

[0070] If the temperature of the bottom of the melting furnace is too high, the inner side of the cooling structure of the cooling device can be placed close to the hard brick part of the bottom of the pool, and rapid and accurate cooling of the bottom of the pool can be achieved by adjusting the fan frequency and the air valve.

[0071] If the breast wall temperature of the melting furnace body is too high, causing defects such as stones caused by exudate, the cooling device can be used to cool the breast wall in this area, change the temperature gradient in the thickness direction of the breast wall bricks, so as to reduce or delay the exudate of the electric fused bricks.

[0072] The cooling structure, cooling device and glass melting furnace provided in the present application are introduced in detail above. For those skilled in the art, according to the ideas of the embodiments of the present application, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present application.
