Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refractory material inspection, in particular to a refractory material inspection device for hot blast stoves. Background Art
[0002] Refractory materials for hot blast stoves have diverse compositions, including acidic, alkaline, and neutral types, and are classified according to refractoriness and shape and size. Their performance indicators include refractoriness, load softening temperature, etc. Their functions are heat insulation, resistance to chemical erosion, and support and protection of the furnace body. The production process includes raw material preparation, forming processing, firing, etc. Refractory materials for hot blast stoves need to be tested for the following main reasons. Firstly, their working environment is harsh, and high temperature, pressure, and chemical erosion will affect the material properties. Testing can ensure that the materials can withstand these conditions. Secondly, to ensure the safe and stable operation of the hot blast stove and avoid failures caused by refractory material problems. Thirdly, it can ensure product quality and thermal efficiency. Subsequently, a refractory material inspection device for hot blast stoves is required to test whether the refractory materials are qualified and can be put into use.
[0003] The structures of refractory material inspection devices for hot blast stoves are rich and diverse. In terms of physical property testing, the volume density measurement structure includes a high-precision electronic balance and a special measuring container. The apparent porosity detection structure includes a vacuum pumping device, a liquid medium-related system, and measuring instrument sensors. The normal temperature compressive strength and flexural strength tests rely on a universal testing machine and a flexural testing machine respectively, equipped with a variety of sensors and a precise transmission system. The permanent linear change detection under heating depends on a heating furnace, a measuring device, and a data processing unit. The thermal conductivity detection is achieved through a heating plate, a cooling plate, etc. However, the normal temperature compressive strength structure therein contains multiple parts. The main frame is made of high-strength metal, and there are options of four-column type and portal type structures to provide stable support for the device. The chucks of the specimen fixing structure are divided into flat mouth and wedge types, and have an adjustment mechanism to adapt to different specimens. The pressure application structure relies on a motor and a ball screw drive system to achieve stable and precise pressure application. The pressure and deformation measurement structure uses pressure sensors and strain gauges or displacement sensors to measure relevant data. The data acquisition and control system can convert electrical signals into digital signals, and operators can set parameters and view, store, and analyze data in real time.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0031] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: a refractory material inspection device for a hot blast stove, including an outer shell 1. The outer shell 1 can be made of stainless steel material, having good strength and corrosion resistance. An adaptive clamping assembly is fixedly connected inside the outer shell 1, and the adaptive clamping assembly is used for the function of clamping refractory materials; the adaptive clamping assembly includes a hydraulic cylinder 15. The cylinder body and piston rod and other components of the hydraulic cylinder 15 can be made of high-strength alloy steel material to ensure sufficient strength and durability. The outer wall of the hydraulic cylinder 15 is fixedly connected inside the outer shell 1. The output end of the hydraulic cylinder 15 is fixedly connected with a connecting rod 16. The side wall of the connecting rod 16 is rotatably connected with a hollow rod 17. The hollow rod 17 can be made of aluminum alloy material, which is light in weight and has a certain strength. The inner wall of the outer shell 1 is fixedly connected with a second support plate 14. The second support plate 14 can be made of cast iron material, having strong bearing capacity. The top of the second support plate 14 is fixedly connected with a second fixed column 21. The top of the second fixed column 21 is fixedly connected with a third support plate 22. The side wall of the hollow rod 17 is rotatably connected with a slide block 20. The top of the second support plate 14 is fixedly connected with a slide rail 18. The slide rail 18 can be made of steel and subjected to surface treatment to improve wear resistance and smoothness. The outer wall of the slide rail 18 is slidably connected inside the slide block 20. The top of the slide block 20 is fixedly connected with a clamping block 19. The clamping block 19 can be made of rubber material, which can not only provide a certain frictional force but also avoid damaging the refractory materials.
[0032] Specifically, the output end of the hydraulic cylinder 15 drives the connecting rod 16 to rotate. During this process, the hydraulic cylinder 15 provides stable and powerful power. When the connecting rod 16 rotates, due to its mechanical connection, it drives the hollow rod 17 on the side wall to rotate. While the hollow rod 17 is rotating, it drives the slider 20 on the side wall to slide along the outer wall of the slide rail 18. It should be noted that one node of the hollow rod 17 is fixed to the side wall of the slide rail 18. This design is extremely ingenious, which enables the hollow rod 17 not to shift in position during rotation, so that it can accurately drive the clamping blocks 19 on both sides to converge. Moreover, the design of the clamping block 19 is unique. It has a notch on one side, and the notch is triangular. This triangular notch design has strong adaptability. It can not only clamp cylindrical refractory materials. When the cylinder is placed in the notch, the three sides of the triangle can well fit the surface of the cylinder to provide stable clamping force; it can also clamp square refractory materials. The sides of the square can form a certain fit with the sides of the triangular notch to ensure the stability of clamping; even for some irregularly shaped refractory materials, it can also be adapted to clamp. For example, some irregular shapes with protrusions or depressions. The triangular notch can be adjusted and fitted according to its shape to achieve the effect of clamping refractory materials of different shapes and sizes, greatly improving the versatility and flexibility of the device in practical applications.
[0033] Refer to Figure 1 、 Figure 3 and Figure 4 As shown in FIGS.
[0034] Specifically, a powerful suction force is generated at the output end of the suction fan 26. This suction force can effectively act on the entire device. When the suction fan 26 is working, the suction force at its output end will be transmitted to the inside of the housing 1 through the ventilation pipe 28. The ventilation pipe 28 plays a crucial conveying role in the whole system. It can not only guide the flow direction of the air flow, but also has a filter plate 31 fixed inside it. The presence of the filter plate 31 is of great significance. It can block larger particles from entering the inside of the material loading box 27, thus effectively preventing possible blockage or other adverse effects caused by particulate impurities to the material loading box 27, achieving a good dust removal effect. When it is necessary to clean the material loading box 27, the operator can pull the second handle 24. When an external force is applied to the second handle 24, the force on the second handle 24 will drive the second rotating door 23 to rotate. The second rotating door 23 is designed very cleverly. It is connected and fixed to the side wall of the housing 1 through the second hinge 25. The connection method of the hinge enables the second rotating door 23 to be opened and closed flexibly, facilitating operation. In addition, when disassembling the filter plate 31, the operator uses a wrench to rotate the bolt 30 manually. After the bolt 30 is screwed off, the connection and fixation between the filter plate 31 and the material loading box 27 are released. At this time, the material loading box 27 can be easily pulled out, and then the dust accumulated inside it can be thoroughly processed, ensuring the normal operation of the entire device and a good working environment.
[0035] Refer to Figure 1 - Figure 2 At the top of the housing 1, a warning light 4 is fixedly connected. The protective shell of the warning light 4 can be made of plastic material, and the lamp shade can be made of transparent PC material. Inside the housing 1, a display screen 2 is fixedly connected, and a pressure gauge 3 is fixedly connected. The protective shell of the pressure gauge 3 can be made of stainless steel material, and the internal sensitive element can be selected from suitable metal or semiconductor materials according to specific requirements. On the side wall of the housing 1, a first hinge 8 is fixedly connected. On the side wall of the first hinge 8, a first rotating door 7 is fixedly connected. On the side wall of the first rotating door 7, a first handle 6 is fixedly connected. At the top of the housing 1, a driving component is provided. The driving component is used to control the pressure and test the hardness function of refractory bricks. The driving component includes a first motor 5. The bottom of the first motor 5 is fixedly connected to the top of the housing 1. The output end of the first motor 5 is fixedly connected with a threaded rod 9. The threaded rod 9 can be made of high-strength alloy steel material, having good wear resistance and strength. The outer wall of the threaded rod 9 is threadedly connected with a first support plate 11. Inside the first support plate 11, a sliding sleeve 12 is fixedly connected. The sliding sleeve 12 can be made of copper alloy material, having good wear resistance and lubricity. Inside the sliding sleeve 12, a first fixed column 10 is slidably connected. The first fixed column 10 can be made of stainless steel material. The top of the first fixed column 10 is fixedly connected to the inner wall of the housing 1. The bottom of the first support plate 11 is fixedly connected with an inspection pressure head 13. The inspection pressure head 13 can be made of cemented carbide material, having high hardness and good wear resistance, and can accurately test the hardness of refractory materials.
[0036] Specifically, when using the refractory material inspection device for the hot blast stove, first, the first handle 6 needs to be pulled. When a pulling force is applied to the first handle 6, the first handle 6 will drive the first rotating door 7 to rotate. Here, the first rotating door 7 is fixed to the side wall of the housing 1 through the first hinge 8. The connection method of the first hinge 8 ensures that the first rotating door 7 can be smoothly opened, providing a convenient passage for subsequent operations. After entering the device for internal operations, start the device. The output end of the first motor 5 drives the threaded rod 9 to rotate. The first motor 5 serves as the power source, providing stable driving force for the whole process. When the threaded rod 9 rotates, it will drive the first support plate 11 to rotate by virtue of the threaded connection. At the same time, the first support plate 11 slides on the outer wall of the first fixed column 10, and the sliding sleeve 12 fixed inside the first support plate 11 slides on the outer wall of the first fixed column 10. It is worth mentioning that the sliding sleeve 12 is made of copper, and copper has good wear resistance and lubricity, which will greatly reduce the problem of jamming during the sliding process and ensure the smoothness of the whole movement process. Immediately afterwards, under the action of force, the first support plate 11 will drive the inspection pressure head 13 at the bottom to press on the surface of the refractory material, thus achieving the effect of normal temperature compressive resistance of the refractory material. During the whole inspection process, the normal operation status of the device can be visually checked through the warning lamp 4. When the warning lamp 4 lights up in different colors or states, the operator can timely understand whether there are faults or abnormal conditions in the device, and the magnitude of the downward pressure can be adjusted through the display screen 2. The display screen 2 provides a visual operation interface, facilitating the operator to accurately set the pressure according to specific inspection requirements. At the same time, the intensity of the downward pressure can also be checked through the pressure gauge 3. The pressure gauge 3 can display the current pressure value applied to the refractory material in real time, providing accurate data support for the inspection process and ensuring the reliability and accuracy of the inspection results.
[0037] Working principle: When using the refractory material inspection device for hot blast stoves, first pull the first handle 6. The first handle 6 drives the first rotating door 7 to rotate. The first rotating door 7 is fixed to the side wall of the housing 1 through the first hinge 8, and at the same time, ensure the smooth opening of the first rotating door 7. Subsequently, the output end of the hydraulic cylinder 15 drives the connecting rod 16 to rotate. The rotation of the connecting rod 16 drives the hollow rod 17 on the side wall to rotate. While the hollow rod 17 is rotating, it drives the slider 20 on the side wall to slide on the outer wall of the slide rail 18. And one node of the hollow rod 17 is fixed to the side wall of the slide rail 18. Thus, when the hollow rod 17 rotates, it will not shift in position, but drive the clamping blocks 19 on both sides to converge. The clamping block 19 is designed with a notch on one side, and the notch is triangular. The triangle can clamp cylinders and can also clamp squares. And it can also adapt to clamp some irregular shapes. In this way, the effect of clamping refractory materials of different shapes and different sizes is achieved. Next, the output end of the first motor 5 drives the threaded rod 9 to rotate. At the same time, the rotation of the threaded rod 9 drives the first support plate 11 to rotate. The first support plate 11 slides on the outer wall of the first fixed column 10. At the same time, the sliding sleeve 12 fixed inside the first support plate 11 slides on the outer wall of the first fixed column 10. Since the sliding sleeve 12 is made of copper, the problem of jamming will be greatly reduced. Then, the first support plate 11 drives the inspection pressure head 13 at the bottom to press on the surface of the refractory material, achieving the effect of normal temperature compression resistance of the refractory material. Next, the output end of the suction fan 26 generates suction, and the suction is applied to the inside of the housing 1 through the ventilation pipe 28. A filter plate 31 is fixed inside the ventilation pipe 28 to prevent larger particles from entering the inside of the loading box 27, achieving the effect of dust removal. Then, pull the second handle 24. The force on the second handle 24 drives the second rotating door 23 to rotate. The second rotating door 23 is also connected and fixed to the side wall of the housing 1 through the second hinge 25. In addition, by manually using a wrench to rotate the bolt 30, after the filter plate 31 is unscrewed, the loading box 27 can be pulled out to deal with the dust inside. And the normal operation status of the device can be checked through the warning light 4. The size of the downward pressure can be adjusted through the display screen 2, and the intensity of the downward pressure can be checked through the pressure gauge 3.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
