Description

Technical Field

[0001] This utility model relates to the field of post-processing technology for refractory brick preparation, and in particular to a refractory brick cooling rack. Background Technology

[0002] After refractory bricks are fired, they need to be cooled in stages. Generally, when the temperature is above 800℃, they need to be cooled at a rate of less than 50°C / h to eliminate thermal stress and control phase transformation. When the temperature is between 400℃ and 800℃, they need to be cooled at a rate of 50 to 100°C / h to balance cooling efficiency and stress release. When the temperature is below 400℃, cooling can usually be accelerated.

[0003] However, the current methods for cooling refractory bricks in the low-temperature range mainly include natural cooling and blowing air through a cold air blower. During cooling, the refractory bricks are simply placed on a metal frame. However, no matter what method is used, it is impossible to cool all six sides of the refractory bricks evenly. At least one side will not be in contact with the air or other medium, resulting in slow cooling. Utility Model Content

[0004] To address the aforementioned shortcomings, this invention provides a refractory brick cooling rack that can simultaneously cool all six sides of multiple refractory bricks, thereby increasing the cooling speed.

[0005] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0006] A refractory brick cooling rack, comprising:

[0007] The mounting bracket includes a pair of end plates, with multiple bottom liquid cooling modules arranged in a straight line array fixed at the lower ends of the two end plates. Between the two end plates, there are also multiple pairs of side liquid cooling modules located on both sides above the bottom liquid cooling modules.

[0008] The upper cover is assembled on the upper end of the fixed frame and includes an H-shaped hand-held plate. Multiple top liquid cooling modules are provided at the lower end of the top liquid cooling module. Multiple pairs of end liquid cooling modules are fixed at the lower end of the top liquid cooling module. When each refractory brick is cooled, it is located between a bottom liquid cooling module, a top liquid cooling module, a pair of side liquid cooling modules, and a pair of end liquid cooling modules.

[0009] Furthermore, the lower end of the end plate is provided with multiple first bases, and the lower end of the bottom liquid cooling module is provided with multiple second bases.

[0010] Furthermore, multiple pairs of side grooves are provided on the side of the end plate, and the two ends of the side liquid cooling module are respectively inserted into the side grooves of the two end plates.

[0011] Furthermore, multiple vertical plates are provided at the lower ends of the two parallel sides of the H-shaped handheld panel, and the top liquid cooling module is located at the lower end of the vertical plates.

[0012] Furthermore, each of the bottom liquid cooling module, side liquid cooling module, and top liquid cooling module is provided with a pair of first connecting end pipes at one end, and each of them is provided with multiple first U-shaped pipes connected end to end inside. One first connecting end pipe is used to input coolant, and the other first connecting end pipe is used to output coolant. The first U-shaped pipes at both ends are respectively connected to the first connecting end pipes.

[0013] Furthermore, the end liquid cooling module is provided with a second connecting end pipe at both ends, and the top liquid cooling module is provided with a plurality of second U-shaped pipes connected end to end. The second U-shaped pipes at both ends are connected to the second connecting end pipes respectively. Among the plurality of end liquid cooling modules parallel to the length direction of the end plate, a connecting pipe is installed between the relative second connecting end pipes of two adjacent end liquid cooling modules. A second connecting end pipe of the end liquid cooling module at one end is used to input coolant, and a second connecting end pipe of the end liquid cooling module at the other end is used to output coolant.

[0014] The beneficial effects of this technical solution are as follows:

[0015] 1. In a rectangular array of multiple refractory bricks on a fixed frame, the top, bottom and four peripheral surfaces of each refractory brick can continuously receive liquid cooling heat exchange. When the refractory bricks are cooled, they are located between a bottom liquid cooling module, a top liquid cooling module, a pair of side liquid cooling modules and a pair of end liquid cooling modules, thus improving the cooling speed of the refractory bricks.

[0016] 2. It is convenient to put in and take out refractory bricks. The fixing frame is used to support the refractory bricks from the bottom. The upper cover can be assembled by hand. Attached Figure Description

[0021] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0022] like Figures 1-4The refractory brick cooling rack shown includes a fixed frame 1 and an upper cover 2.

[0023] The mounting bracket 1 includes a pair of end plates 11. The side of the end plates 11 has multiple pairs of side grooves. Multiple bottom liquid cooling modules 12 arranged in a straight line array are welded and fixed to the lower ends of the two end plates 11. Multiple pairs of side liquid cooling modules 13 are also provided between the two end plates 11, which are located on both sides above the bottom liquid cooling modules 12. The two ends of the side liquid cooling modules 13 are respectively inserted into the side grooves of the two end plates 11. Multiple first bases 14 are provided at the lower end of the end plates 11, and multiple second bases 15 are provided at the lower end of the bottom liquid cooling modules 12.

[0024] The upper cover 2 is assembled on the upper end of the fixing frame 1, including an H-shaped handheld plate 21. Multiple vertical plates 22 are respectively provided at the lower ends of its two parallel sides. A top liquid cooling module 23 is provided at the lower end of each vertical plate 22. Specifically, two vertical plates 22 are fixed to the upper end of each top liquid cooling module 23. A pair of first connecting pipes 3 are provided at one end of each of the bottom liquid cooling module 12, side liquid cooling module 13, and top liquid cooling module 23. Multiple first U-shaped pipes 4 connected end-to-end are provided inside each of these. One first connecting pipe 3 is used for inputting coolant, and the other first connecting pipe 3 is used for outputting coolant. The first U-shaped pipes 4 at both ends are connected to the first connecting pipes 3 respectively. Multiple pairs of end liquid cooling modules 24 are welded and fixed to the lower end of the top liquid cooling module 23. The two ends of each end liquid cooling module 24... Each end is provided with a second connecting end pipe 5. The top liquid cooling module 23 has multiple second U-shaped pipes 6 connected end to end. The second U-shaped pipes 6 at both ends are connected to the second connecting end pipes 5 respectively. Among the multiple end liquid cooling modules 24 parallel to the length direction of the end plate 11, a connecting pipe 25 is installed between the relative second connecting end pipes 5 of two adjacent end liquid cooling modules 24. A second connecting end pipe 5 of the end liquid cooling module 24 at one end is used to input coolant, and a second connecting end pipe 5 of the end liquid cooling module 24 at the other end is used to output coolant. When each refractory brick is cooled, it is located between a bottom liquid cooling module 12, a top liquid cooling module 23, a pair of side liquid cooling modules 13, and a pair of end liquid cooling modules 24 respectively.

[0025] Preferably, after assembly, the height of the second connecting end pipe 5 is higher than the height of the side liquid cooling module 13, which facilitates the insertion and removal of refractory bricks.

[0026] Preferably, flange rings are formed at the outer ends of the first connecting pipe 3, the second connecting pipe 5, and both ends of the connecting pipe 25. When connecting to an external coolant input or output source, or connecting the connecting pipe 25 between two second connecting pipes 5, the connection can be stably fixed. The external pipes connected to each flange ring of the upper cover 2 can be a combination of rigid pipes and flexible pipes, which makes it easy to maintain the connection when the upper cover 2 moves.
