Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing and production technology, and in particular to a refractory brick cooling device. Background Technology

[0002] The cooling process in refractory brick manufacturing is a crucial but often overlooked step. Cooling is not simply about lowering the temperature of the hot bricks; it directly affects the mechanical strength, mineral phase composition, dimensional stability, and service life of the final product. The problem lies in the following: some existing technologies use spraying to cool refractory bricks. The main drawback of spray cooling is its uneven, unidirectional heat exchange, which leads to significant thermal stress and stress gradients within the bricks, making them more prone to cracking, spalling, or deformation. Other existing technologies use immersion to cool refractory bricks, but stacking multiple bricks in an immersion tank is inconvenient, and the contact surfaces between adjacent bricks are not conducive to heat dissipation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a refractory brick cooling device, which immerses refractory bricks in a cooling pool in an array.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed: A refractory brick cooling device is installed inside a kiln tunnel. The device includes a conveying unit, a pushing mechanism, a cooling pool, a lifting device, and a suspension plate.

[0005] The conveying section is located at the outer end of the cooling pool. The conveying section is used to transport refractory bricks to be cooled, and the conveying direction of the conveying section is perpendicular to the long axis of the cooling pool. The lifting device clamps the suspension plate, positioning it above the cooling pool, with the top surface of the suspension plate flush with the top surface of the conveying section. The pushing mechanism includes a linear stroke component and a push plate. The push plate is located outside the conveying section. The linear stroke component is connected to the push plate and is used to move the push plate toward the cooling pool, thereby moving several refractory bricks on the conveying section onto the suspension plate in multiple steps. The lifting device is used to lower the suspension plate into the cooling pool for cooling.

[0006] Furthermore, it also includes a guide frame, which is suspended above the suspension plate. The end of the guide frame facing the conveying part has a pointed structure, and the other end of the guide frame is fixedly connected to the outer wall of the cooling pool by a bracket. The push plate includes a horizontal plate and two vertical plates at its bottom. The horizontal plate is connected to the linear travel member. The inner distance between the two vertical plates is based on allowing the guide frame to pass through. The two vertical plates are used to push two refractory bricks respectively, and the guide frame is used to expand the inner distance between two adjacent refractory bricks.

[0007] Furthermore, multiple columns are installed at the bottom of the cooling pool to support the suspension plate.

[0008] Furthermore, the suspension plate includes multiple rollers arranged in an array.

[0009] Furthermore, a roller is provided at the top of each end of the cooling pool.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model uses an immersion method to cool refractory bricks. The bricks are completely immersed in the cooling medium, and all surfaces are in contact with the cooling medium. Cooling and contraction in all directions are relatively synchronous, and the resulting thermal stress is relatively balanced in three dimensions, making it less likely to form large-scale stress concentrations that cause overall deformation.

[0011] 2. In this utility model, the refractory bricks are not stacked in the cooling pool, but are arranged at certain intervals on a suspension plate. The suspension plate is lowered into the cooling pool by a hoist for cooling. This not only helps the refractory bricks to cool and dissipate heat evenly, but also facilitates the process of taking and placing the refractory bricks. Attached Figure Description

[0012] Figure 1 A diagram showing the external structure of the kiln tunnel is provided. Figure 2 A top view of the cooling equipment is shown; Figure 3 A top view of a cooling device with a guide frame is shown; Figure 4 A diagram of the pusher plate structure is shown. Detailed Implementation

[0013] This embodiment provides a refractory brick cooling device, located at... Figure 1 The kiln tunnel 1 shown is part of existing technology and will not be described in detail here. Figure 2 As shown, the equipment includes a conveying unit 2, a pushing mechanism 3, a cooling pool 4, a lifting device, and a suspension plate 5.

[0014] Specifically, such as Figure 2 As shown, the conveying section 2 is located at the outer end of the cooling pool 4. The conveying section 2 is used to convey refractory bricks to be cooled, and the conveying direction of the conveying section 2 is perpendicular to the long axis of the cooling pool 4.

[0015] Specifically, such as Figure 2 As shown, the lifting device clamps the suspension plate 5, so that the suspension plate 5 is above the cooling pool 4, and the top surface of the suspension plate 5 is flush with the top surface of the conveying section 2. It should be noted that the structure of the lifting device is not shown in the attached figure, because the lifting device is a conventional technology and will not be described in detail here.

[0016] Specifically, such as Figure 2 As shown, the suspension plate 5 includes multiple rollers 51 arranged in an array, and the array direction of the multiple rollers 51 is parallel to the long axis of the cooling pool 4.

[0017] Specifically, such as Figure 2 As shown, the pushing mechanism 3 includes a linear travel member 31 and a push plate 32. The push plate 32 is located outside the conveying section 2, and the linear travel member 31 is located outside the cooling pool 4. The long axis of the linear travel member 31 is parallel to the long axis of the cooling pool 4. The linear travel member 31 is connected to the push plate 32 and is used to move the push plate 32 toward the cooling pool 4, thereby moving the refractory bricks on the conveying section 2 to the suspension plate 5 in multiple steps. "Multiple steps" means that the push plate 32 pushes two refractory bricks at a time and then returns to its original position. The conveying section 2 continues to run, and the push plate 32 pushes two more refractory bricks. A certain interval must be maintained between the two adjacent pushes of refractory bricks.

[0018] Two points need to be clarified here: First, there are many ways to implement the linear stroke component 31, such as using a motor to drive the lead screw; Secondly, to facilitate the pushing of refractory bricks from the conveying section 2 onto the suspension plate 5, and to facilitate the removal of the refractory bricks from the suspension plate 5 after cooling, such as... Figure 2 As shown, in this embodiment, a roller 51 is provided at the top of both ends of the cooling pool 4, and the roller 51 on the cooling pool 4 is at the same height as the roller 51 on the suspension plate 5.

[0019] Instructions for use: The lifting device clamps the suspension plate 5, positioning it above the cooling pool 4; the linear travel member 31 moves the push plate 32 towards the cooling pool 4, thereby moving the refractory bricks from the conveying section 2 onto the suspension plate 5 in multiple stages; after the refractory bricks are arranged, the lifting device lowers the suspension plate 5 into the cooling pool 4 for cooling. To further improve the stability of the suspension plate 5, such as... Figure 2 As shown, in this embodiment, the bottom of the cooling pool 4 is provided with four columns 41, which are used to support the suspension plate 5.

[0020] When conveying refractory bricks in conveyor section 2, if the distance between two adjacent refractory bricks is too small, it may affect subsequent cooling and heat dissipation. Considering this issue, if... Figure 3 As shown, this embodiment adds a guide frame 6, which is suspended above the suspension plate 5. One end of the guide frame 6 facing the conveying part 2 has a pointed structure 61, and the other end of the guide frame 6 is fixedly connected to the outer wall of the cooling pool 4 via a bracket 62. Figure 3 , Figure 4 As shown, the push plate 32 includes a horizontal plate 321 and two vertical plates 322 located at its bottom. The horizontal plate 321 is connected to the linear travel member 31. The inner distance between the two vertical plates 322 is such that the guide frame 6 can pass through. The two vertical plates 322 are used to push two refractory bricks respectively. The guide frame 6 is used to expand the inner distance between two adjacent refractory bricks.

[0021] Operating method: The lifting device clamps the suspension plate 5, positioning it above the cooling pool 4; the linear travel member 31 moves the push plate 32 toward the cooling pool 4, thereby moving the refractory bricks on the conveying section 2 onto the suspension plate 5 in multiple steps. During this process, the two refractory bricks pushed by the push plate 32 first contact the sharp corner structure 61. Under the action of the sharp corner structure 61, the distance between the two refractory bricks gradually increases, and then they move along the outer wall of the guide frame 6. After the refractory bricks are arranged, the lifting device lowers the suspension plate 5 into the cooling pool 4 for cooling.

[0022] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
