Description

Technical Field

[0001] This utility model relates to the field of refractory material attached metal recycling technology, specifically to a kiln inner wall refractory brick cutting device. Background Technology

[0002] In kilns widely used in industries such as metal smelting, glass manufacturing, and ceramic sintering, the inner walls are usually constructed with refractory materials such as refractory bricks to withstand high-temperature environments. During long-term high-temperature operation, molten or volatilized metals (such as zinc, lead, tin, copper, and their alloys) will inevitably seep into the refractory materials of the kiln inner wall. This metal penetration phenomenon intensifies as the kiln operation time increases, resulting in a large amount of metal residue adhering to and accumulating in the refractory materials, especially in the part near the working surface of the furnace.

[0003] When a kiln is maintained or reaches the end of its service life, these waste refractory materials (mainly refractory bricks) with metal residue are dismantled. Since they often contain metal, they have a certain recycling value. However, the amount of metal residue concentrated in different areas of the same refractory brick varies significantly. The surface area near the hot side of the kiln has a higher metal content, while the deeper area near the cold side has a relatively lower metal content. Therefore, it is often necessary to separate a refractory brick during recycling to improve the efficiency of metal recovery. In addition, the distance that the metal penetrates varies depending on the length of time the kiln has been used.

[0004] Currently, the recycling and processing of metal residues in these waste refractory materials usually requires pre-cutting and separation before subsequent processes. The traditional method is to manually use a handheld cutting tool to cut the refractory bricks into two parts along the approximate boundary of metal content. However, this method has many drawbacks. First, it is risky to operate. Manual hand-cutting at close range easily generates a lot of dust, and the high-speed rotation of the cutting blade poses a risk of breakage, which threatens the safety of the operator. Second, it lacks precision. It is often inconvenient to position the bricks during cutting, which can easily lead to over-cutting or under-cutting. Therefore, a device is needed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a kiln inner wall refractory brick cutting device, which solves the problems of high risk and inconvenient positioning during the separation of refractory bricks.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a kiln inner wall refractory brick cutting device, including a base plate and a support leg fixedly connected to the lower surface of the base plate, a drive motor fixedly connected to the lower surface of the base plate, a cutting blade fixedly connected to the output end of the drive motor, and a through groove opened on the upper surface of the base plate for the cutting blade to pass through, so that the cutting blade passes through the through groove to cut the material above. The upper surface of the base plate is provided with a pushing mechanism to push the material toward the cutting blade. One side of the pushing mechanism is provided with an adjustment mechanism to adjust the cutting position of the refractory brick relative to the cutting blade. The upper surface of the base plate is provided with an arc-shaped guide plate to discharge the material.

[0007] Optionally, the pushing mechanism includes a fixed plate, a push plate, and a guide rod. The fixed plate is fixedly connected to the upper surface of the base plate. The guide rod passes through the fixed plate and guides it to slide relative to the fixed plate. The push plate is fixedly connected to the side of the guide rod near the cutting blade. One side of the push plate is in contact with the material to push the material to move.

[0008] Optionally, there are two guide rods, and a connecting rod is fixedly connected to the end of each guide rod away from the push plate. The connecting rod is used to connect adjacent guide rods.

[0009] Optionally, the push plate has a relief groove in the middle that is away from the cutting blade to avoid the cutting blade.

[0010] Optionally, the adjustment mechanism includes a positioning plate and a threaded rod. One side of the push plate is provided with an L-shaped bend. The threaded rod is threadedly connected to one side of the push plate. The positioning plate slides guidely on one side of the push plate. One end of the threaded rod is rotatably connected to one side of the positioning plate.

[0011] Optionally, the upper surface of the push plate is provided with a scale, and the upper surface of the positioning plate is provided with an arrow pointing toward the scale to determine the position of the positioning plate in the width direction of the base plate.

[0012] Optionally, a reinforcing rib is fixedly connected to one side of the fixing plate to increase the strength of the fixing plate and reduce the deformation of the fixing plate.

[0013] Optionally, the upper surface of the base plate is provided with auxiliary wheels.

[0014] This utility model provides a device for cutting refractory bricks for the inner wall of a kiln, which has the following advantages: This utility model provides a refractory brick cutting device for the inner wall of a kiln. Through the coordinated arrangement of a base plate, a cutting blade, and a pushing mechanism, the cutting blade, driven by a motor, rotates to cut the refractory material, thereby cutting off the end with the higher metal residue. This improves subsequent recycling efficiency. The pushing mechanism eliminates the need for manual cutting, keeping the operator's hands away from the cutting blade and reducing the risk of cutting accidents. An adjustment mechanism on the pushing mechanism allows for precise positioning of the cutting location, facilitating cutting from the point of difference in metal residue content. A guide plate on the base plate separates the cut material into two parts: one with more metal residue and the other with less. The guide plate further pushes these two parts to opposite sides for targeted processing. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: a kiln inner wall refractory brick cutting device, including a base plate 1 and a support leg 2 fixedly connected to the lower surface of the base plate 1. A drive motor is fixedly connected to the lower surface of the base plate 1, and a cutting blade 3 is fixedly connected to the output end of the drive motor. A through groove 4 is opened on the upper surface of the base plate 1 for the cutting blade 3 to pass through, so that the cutting blade 3 passes through the through groove 4 to cut the material above.

[0019] The upper surface of the base plate 1 is provided with a pushing mechanism to push the material toward the cutting blade 3. An adjustment mechanism is provided on one side of the pushing mechanism to adjust the cutting position of the refractory brick relative to the cutting blade 3. The upper surface of the base plate 1 is provided with an arc-shaped guide plate 14 to discharge the material.

[0020] The bottom of the support leg 2 is equipped with a countersunk hole, which can be used to fix the position of the support leg 2, thereby reducing the impact generated during the cutting process. The drive motor drives the cutting blade 3 to rotate. The size of the through groove 4 is larger than the size of the cutting blade 3 to prevent interference with the groove when the cutting blade 3 rotates. The rotation of the cutting blade 3 can cut the refractory brick, separating the refractory brick into an end with a higher metal content and an end with a lower metal content. The pushing mechanism can push the refractory brick to one side of the cutting blade 3, keeping the operator's hands away from the cutting blade 3 and improving the safety of the cutting process. The adjustment mechanism can position the material according to the current kiln usage time. The length of the cutting blade (the longer the time, the longer the distance the metal penetrates into the refractory brick) is adjusted to change the position of the adjustment mechanism, so that the cutting blade 3 can accurately separate the refractory brick from the position of metal content, thereby improving the efficiency of subsequent use. After the cutting is completed, the refractory brick is cut again. The cut refractory brick is pushed forward. The guide plate 14 can guide the movement direction of the refractory brick, making it easier to separate the refractory brick into two parts, which is more convenient for subsequent processing. The rotation direction of the cutting blade 3 is towards the pushing mechanism side, which is clockwise when viewed from the left side of the figure. It provides downward pressure while cutting to prevent the refractory brick from shaking during the cutting process.

[0021] In this embodiment, as a preferred option, the pushing mechanism includes a fixed plate 5, a push plate 6, and a guide rod 7. The fixed plate 5 is fixedly connected to the upper surface of the base plate 1. The guide rod 7 passes through the fixed plate 5 and guides and slides relative to the fixed plate 5. The push plate 6 is fixedly connected to the side of the guide rod 7 near the cutting blade 3. One side of the push plate 6 is in contact with the material to push the material to move. There are two guide rods 7. A connecting rod 8 is fixedly connected to the end of the guide rod 7 away from the push plate 6. The connecting rod 8 is used to connect adjacent guide rods 7.

[0022] The connecting rod 8 is equipped with a handle, which provides a gripping part while connecting the two guide rods 7, making it more convenient to operate. By pushing the connecting plate to move, the connecting plate can push the guide rod 7 to move, and further push the push plate 6 at one end of the guide rod 7 to move, so that the push plate 6 can push the refractory brick on one side of the push plate 6 towards the cutting blade 3, thereby improving safety. There are two guide rods 7, which can improve the stability of the push plate 6 during the movement and reduce the possibility of the push plate 6 tilting.

[0023] In this embodiment, as a preferred option, the push plate 6 is provided with a relief groove 10 in the middle that is away from the cutting blade 3 to avoid the cutting blade 3.

[0024] The clearance groove 10 is recessed to one side. When the refractory brick is pushed toward the cutting blade 3, after the cutting blade 3 has cut the refractory brick, the clearance groove 10 can avoid the position of the cutting blade 3, ensuring that the cutting blade 3 cuts through the refractory brick while avoiding interference between the cutting blade 3 and the push plate 6, thus improving safety.

[0025] In this embodiment, as a preferred option, the adjustment mechanism includes a positioning plate 11 and a threaded rod 12. One side of the push plate 6 is provided with an L-shaped bend. The threaded rod 12 is threadedly connected to one side of the push plate 6. The positioning plate 11 is guided and slidably on one side of the push plate 6. One end of the threaded rod 12 is rotatably connected to one side of the positioning plate 11. The upper surface of the push plate 6 is provided with a scale 13. The upper surface of the positioning plate 11 is provided with an arrow pointing towards the scale 13 to determine the position of the positioning plate 11 in the width direction of the base plate 1.

[0026] The rotating threaded rod 12 can drive the positioning plate 11 at one end to move, so that the positioning plate 11 slides along one side of the push plate 6. The push plate 6 and the positioning plate 11 form a right angle. When cutting refractory bricks, the placement position of the refractory bricks can be directly positioned (one side of the refractory brick is attached to the positioning plate 11, and the other side is attached to the push plate 6. The two work together to position the refractory bricks). The cutting efficiency is higher. At the same time, the positioning plate 11 is provided with an arrow pointing to the scale 13 on the push plate, which makes the adjustment of the position of the positioning plate 11 more accurate.

[0027] In this embodiment, as a preferred option, a reinforcing rib 15 is fixedly connected to one side of the fixing plate 5 to improve the strength of the fixing plate 5 and reduce the deformation of the fixing plate 5, and an auxiliary wheel 9 is provided on the upper surface of the base plate 1.

[0028] The reinforcing ribs are connected to both the base plate 1 and the fixed plate 5, which improves the support strength of the fixed plate 5 and reduces the possibility of bending during use. The auxiliary wheel 9 can reduce the friction between the refractory brick and the base plate 1, making it smoother to push and reducing jamming.

[0029] In this invention, the working steps of the device are as follows: 1. After fixing the support leg 2 at the bottom of the device to the ground, connect the drive motor's connecting wire to the external power cord; 2. Based on the current usage time of the kiln, rotate the threaded rod 12 to adjust the position of the positioning plate 11. After the refractory bricks are placed, ensure that the cutting blade 3 is at the boundary position of the metal residue on the refractory bricks. 3. After adjusting the position of the positioning plate 11, start the drive motor and place the refractory brick on one side of the push plate 6. After placing it, push the connecting rod 8 so that the cutting blade 3 cuts the refractory brick. After the cutting is completed, pull the connecting rod 8 back and place a new refractory brick on one side of the push plate 6. Continue to push the connecting rod 8 to move so that the cutting blade 3 cuts the new refractory brick. Continue in this way until all the refractory bricks are separated. 4. The cut refractory bricks will continue to move forward until they reach the guide plate 14. The guide plate 14 will separate the refractory bricks to both sides, with one side containing refractory bricks with high metal content and the other side containing refractory bricks with low metal content. After separation, they can be processed accordingly.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
