Description

Technical Field

[0001] This invention relates to the field of high-temperature testing equipment technology, specifically a strength testing device for fireproof rock wool boards made from fly ash raw materials under simulated high-temperature conditions. Background Technology

[0002] Fireproof rock wool board is an inorganic fiber made from natural rock or industrial slag through high-temperature melting and fiberization. It possesses excellent thermal insulation, sound insulation, and fireproofing properties, and is widely used in construction, industry, and shipbuilding. Fireproof rock wool board can achieve a fire rating of Class A, making it an internationally recognized fireproof and thermal insulation material for building envelopes. After the production of fireproof rock wool boards, multiple tests are required, including high-temperature strength testing. This test involves high-temperature combustion of the fireproof rock wool boards. Since the boards are primarily composed of fly ash, high-temperature combustion produces a large amount of toxic gases. Furthermore, the combustion zone is a closed cavity, requiring continuous ventilation to maintain the internal gas environment. These gases are high-temperature gases and require subsequent treatment, increasing production costs. Additionally, the internal cavity and the workpiece itself are at high temperatures after high-temperature combustion, necessitating cooling. If the cooling time is too long, cooling equipment is needed. However, excessively rapid cooling can affect the structural stability of the workpiece and the equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a strength testing device for fireproof rock wool boards made from fly ash raw materials under simulated high-temperature conditions, so as to solve the problems raised in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A strength testing device for fireproof rock wool board made from fly ash raw material under simulated high-temperature conditions is disclosed. The testing device includes an outer shell assembly, a combustion assembly, and a surface detection assembly. The combustion assembly is located inside the outer shell assembly, and the surface detection assembly is located inside the outer shell assembly. The surface detection assembly is used to detect changes in the rock wool board caused by high temperatures. An exhaust gas treatment assembly is located at the top of the surface detection assembly. The exhaust gas treatment assembly is used to treat the exhaust gas generated by the heated fly ash raw material. A temperature sensing cooling assembly is located outside the outer shell assembly. The temperature sensing cooling assembly is used to cool the workpiece and the device.

[0005] Furthermore, after the production of fireproof rock wool boards, multiple tests are required, including high-temperature strength testing. This test involves burning the fireproof rock wool boards at high temperatures. The quality of the product is judged based on the burning intensity, insulation efficiency, and surface wear. Since fireproof rock wool boards are mainly composed of fly ash, a large amount of toxic gas is generated during high-temperature combustion. The combustion area is a closed cavity, requiring continuous ventilation to maintain the internal gas environment. The toxic gases cannot be directly emitted and require subsequent treatment, increasing production costs. After testing, the workpiece needs to be removed or replaced. However, due to the high-temperature combustion, the internal cavity and the workpiece itself are at a high temperature and require cooling, which takes a long time. Therefore, cooling equipment is needed to cool them down. However, if the cooling rate is too fast, it will affect the structural stability of the workpiece and the device. The surface inspection component is used to detect wear on the workpiece during high-temperature testing. The exhaust gas component is used to collect and treat the exhaust gas generated by the high-temperature combustion of the fireproof rock wool boards. The temperature sensing cooling component is used to cool the workpiece and the device.

[0006] The outer shell assembly includes a bottom frame, an inner cavity, and a top shell. The bottom frame is located on a horizontal ground, the inner cavity is located on the inner wall of the bottom frame, and the top shell is located at the top of the bottom frame. The top shell is fixedly connected to the bottom frame, and an exhaust gas treatment assembly is located between the bottom of the top shell and the inner cavity.

[0007] Furthermore, the inner cavity serves as a combustion space, and an exhaust gas treatment component is installed between the bottom frame and the top shell. The exhaust gas generated during combustion will slowly rise to the top and be collected and treated by the exhaust gas treatment component.

[0008] The surface inspection assembly includes a movable frame, a telescopic component, and a drive motor. The movable frame is located inside the inner cavity, and the drive motor is located at the top of the top shell. The fixed end of the drive motor is fixedly connected to the top shell, and the output end of the drive motor is located inside the inner cavity and is fixedly connected to the movable frame. One end of the movable frame is provided with a telescopic component, one end of which is fixedly connected to the movable frame, and the other end of which is provided with a clamping component. A laser emitting unit is provided on the inner wall of the movable frame.

[0009] Furthermore, the movable frame is located within the inner cavity and is slidably connected to the inner wall of the inner cavity. A drive motor serves as the power source to control the up-and-down movement of the movable frame. A clamping component is used to cooperate with the workpiece to prevent product displacement. The clamping component is connected to the movable frame via a telescopic component. Thus, the movement of the movable frame drives the telescopic component to move, which in turn drives the clamping component to move. The clamping component is equipped with a laser emitting unit, which is used to detect the wear of the heated surface of the workpiece. Based on the near-infrared or visible light bands, when irradiating the pit, shadow areas or abrupt changes in the reflected light path will appear, thereby determining the wear of the heated surface of the workpiece. Finally, based on the combustion time of the combustion component, the temperature of the inner cavity, the heat insulation effect of the workpiece, and the wear of the heated surface of the workpiece, the overall strength of the workpiece is determined. In conjunction with the movement of the movable frame, the entire surface of the workpiece can be inspected.

[0010] The temperature sensing cooling component includes a cooling pipe, a main semiconductor, and a secondary semiconductor. The cooling pipe is located on the outer wall of the bottom frame and is fixedly connected to the bottom frame. The input end of the cooling pipe is provided with an outer tube, and an inner tube is provided inside the outer tube. An electromagnetic coil is provided between the outer tube and the inner tube. The inner tube is made of nickel. The end of the outer tube away from the cooling pipe is provided with an input pipe. The input pipe, the inner tube, and the cooling pipe are connected. The main semiconductor is located on the side of the clamping member away from the bottom frame. An installation cavity is opened in the movable frame, and the secondary semiconductor is located in the installation cavity.

[0011] Furthermore, the temperature-sensing cooling component is used to cool the device and product after high-temperature detection. The cooling pipe is located on the outer wall of the bottom frame. When coolant flows within the cooling pipe, it cools the device. The cooling efficiency of the cooling pipe is controlled by the flow rate, which is controlled by the inner tube's aperture. Then, the input pipe connects to the external cooling pipe, allowing external coolant to enter the inner tube through the input pipe and then the cooling pipe. A closed loop is formed between the main semiconductor and the secondary semiconductor. After high-temperature detection, the main semiconductor is located outside the device, and the secondary semiconductor is located inside the inner cavity. A significant temperature difference between them creates charge accumulation in the loop, generating voltage and current. The current flows to the electromagnetic coil, causing it to generate magnetic force. Because the inner tube is made of nickel, the generated magnetic force affects the inner tube, causing it to contract towards the central axis. By lowering the inner diameter, the flow rate of the coolant is reduced. As the temperature inside the device gradually decreases with the absorption of coolant, the temperature difference between the main semiconductor and the secondary semiconductor decreases, resulting in a smaller current and a weaker magnetic force from the electromagnetic coil. Consequently, the inner tube diameter increases, accelerating the flow rate of the coolant. This allows the cooling efficiency of the temperature sensing and cooling component to increase rapidly immediately after detection, preventing damage to the device or workpiece from rapid cooling. During detection, the main semiconductor is located at the end of the workpiece furthest from the inner cavity, while the secondary semiconductor is located at the end of the workpiece closest to the inner cavity. This creates a temperature difference between the main semiconductor and the secondary semiconductor due to the workpiece's obstruction. Since the temperature inside the inner cavity is the set heating value, the temperature difference between the two spaces can be used to determine the workpiece's insulation efficiency. A higher current results in better insulation efficiency, and vice versa.

[0012] The exhaust gas treatment component includes a packing column and an air intake pipe. Four air inlets are provided at the bottom of the top shell and are connected to the inner cavity. An air outlet is provided at the top of the top shell. The air intake pipe is located at the top of the top shell and is connected to the air outlet. The packing column is located inside the top shell and is fixedly connected to the inside of the top shell. The packing column is filled with activated carbon.

[0013] Furthermore, during the high-temperature testing process, the continuous high-temperature combustion of the fireproof rock wool board generates a large amount of waste gas and toxic gases. Consequently, the gas inside the cavity cannot be directly discharged and needs to be collected. The suction pipe in the waste gas treatment component is connected to an external gas pipeline, which provides suction. Thus, the gas inside the cavity enters the outer shell through the air inlet and then passes through the filling column. Most of the fine particles and toxic gases in the gas are absorbed by the filling column. However, since the gas is generated during high-temperature testing, the gas temperature is also higher than normal, so it needs to be treated. Subsequent treatment may damage the inner wall of the pipe or the filter material.

[0014] The input pipe penetrates the top shell and is located between the filling column and the air inlet.

[0015] Furthermore, there are two input pipes, both horizontally penetrating the outer casing. The ends of the two input pipes furthest from the outer tube are not connected to each other, while the ends of the two input pipes closest to the outer tube are connected to each other and also connected to the inner tube. Then, one of the two input pipes is connected to an external coolant pipe. During high-temperature testing, the continuous high-temperature spray from the inner cavity causes the secondary semiconductor to reach its highest temperature state, i.e., the maximum temperature difference with the primary semiconductor, resulting in the maximum current. This ultimately causes the inner tube to shrink to its minimum state, thus preventing the cooling pipe from achieving the most basic cooling effect. Moreover, with two input pipes, when connected to the external... The coolant flowing through the input pipe of the coolant pipeline first passes through the inner wall of the outer casing, cooling the high-temperature gas inside. Then, it flows to the branch point, located at the inner pipe connection. At this time, if the device is performing high-temperature detection, the inner pipe will be blocked, and the coolant cannot flow to the cooling pipe. Instead, the coolant flows to another input pipe. After the high-temperature detection is completed, the temperature inside the inner cavity will slowly decrease, resulting in a decrease in the current generated, an expansion of the inner pipe orifice, and an increase in the coolant flow rate, thereby cooling the inner cavity. As the temperature of the inner cavity decreases, the cooling efficiency of the top shell decreases, while the cooling efficiency of the inner cavity increases.

[0016] The combustion assembly includes a nozzle and a delivery pipe. The nozzle is located on the inner wall of the inner cavity, and the delivery pipe is located on the outer wall of the bottom frame. The delivery pipe is connected to the nozzle.

[0017] Furthermore, the combustion assembly is used to burn the workpiece at high temperature. The output end of the nozzle faces the inside of the cavity, and the input end of the nozzle is connected to the delivery pipe. One end of the delivery pipe is connected to the external fuel pipe to deliver fuel to the nozzle. There are three nozzles, which are arranged vertically at equal intervals.

[0018] The bottom of the outer casing assembly is provided with a fixing component, which includes a guide rail and a placement base. One end of the guide rail is fixedly connected to the bottom end of the base frame, and the other end of the guide rail is provided with a placement base. The bottom end of the placement base is provided with a pulley, which cooperates with the guide rail.

[0019] Furthermore, the fixing component is used to place the workpiece, wherein the top of the placement base is provided with a groove that mates with the bottom of the workpiece, and the bottom of the placement base is provided with a pulley, thereby preventing the base from moving on the guide rail via the pulley, thereby allowing the workpiece to engage with the inner cavity to form a sealed space.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. During high-temperature testing, the nozzle of the inner cavity will work continuously, resulting in a large temperature difference between the secondary semiconductor and the primary semiconductor. A current will be generated between the primary and secondary semiconductors, which will energize the electromagnetic coil to generate magnetic force. This will control the inner tube to contract, thus preventing the inner tube from becoming blocked during high-temperature testing. The coolant cannot flow to the cooling pipe and cannot cool the inner cavity. Therefore, during the testing process, only the exhaust gas in the top shell is cooled, and the temperature of the inner cavity is not cooled.

[0021] 2. After the high-temperature test is completed, the temperature inside the inner cavity will gradually decrease, which will lead to a decrease in the value of the current generated, an expansion of the inner tube aperture, and an increase in the flow rate of the coolant, thereby cooling the inner cavity. As the temperature of the inner cavity decreases, the cooling efficiency of the top shell will decrease, while the cooling efficiency of the inner cavity will increase, thus achieving a decrease in the cooling efficiency of the top shell and an increase in the cooling efficiency of the inner cavity.

[0022] 3. In this invention, the main semiconductor is located at the end of the workpiece away from the inner cavity, and the secondary semiconductor is located at the end of the workpiece close to the inner cavity. As a result, the main semiconductor will generate a temperature difference with the secondary semiconductor due to the obstruction of the workpiece. Since the temperature inside the inner cavity is a set heating value, the heat insulation efficiency of the workpiece can be determined. That is, the larger the current, the better the heat insulation efficiency, and vice versa. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example: Figures 1-8 As shown, the present invention provides a technical solution for a fly ash raw material fireproof rock wool board strength testing device under simulated high temperature conditions, including an outer shell assembly 1, a combustion assembly 2, and a surface detection assembly 3. The combustion assembly 2 is provided inside the outer shell assembly 1, and the surface detection assembly 3 is provided inside the outer shell assembly 1. The surface detection assembly 3 is used to detect the changes in the rock wool board caused by high temperature. The top of the surface detection assembly 3 is provided with a waste gas treatment assembly 4, which is used to treat the waste gas generated by the fly ash raw material being heated. The outer shell assembly 1 is provided with a temperature sensing cooling assembly 5, which is used to cool the workpiece and the device.

[0027] Specifically, after the production of fireproof rock wool boards, multiple tests are required, including high-temperature strength testing. This testing involves subjecting the fireproof rock wool boards to high-temperature combustion. The quality of the product is then judged based on the combustion intensity, heat insulation efficiency, and surface wear. Since fireproof rock wool boards are primarily composed of fly ash, a large amount of toxic gases are produced during high-temperature combustion. Furthermore, the combustion area is a closed cavity, requiring continuous ventilation to maintain the gaseous environment within the cavity. The toxic gases cannot be directly emitted and must be... Continuing processing increases production costs. After inspection, the workpiece needs to be picked up or replaced. However, due to high-temperature combustion, the internal cavity of the device and the workpiece itself are in a high-temperature state and need to wait for cooling, which takes too long. Therefore, cooling equipment is needed to cool them down. However, if the cooling rate is too fast, it will affect the structural stability of the workpiece and the device. The surface inspection component 3 is used to perform wear detection on the workpiece itself during high-temperature inspection. The exhaust gas component is used to collect and treat the exhaust gas generated by the high-temperature combustion of the fireproof rock wool board. The temperature sensing cooling component 5 is used to cool the workpiece and the device.

[0028] like Figures 1-3 The outer casing assembly 1 shown includes a bottom frame 11, an inner cavity 12 and a top shell 13. The bottom frame 11 is located on a horizontal ground, the inner cavity 12 is located on the inner wall of the bottom frame 11, the top shell 13 is provided at the top of the bottom frame 11, the top shell 13 is fixedly connected to the bottom frame 11, and an exhaust gas treatment assembly 4 is provided between the bottom end of the top shell 13 and the inner cavity 12.

[0029] Specifically, the inner cavity 12 is a combustion space, and an exhaust gas treatment component 4 is provided between the bottom frame 11 and the top shell 13. The exhaust gas generated by combustion will slowly rise to the top and be collected and treated by the exhaust gas treatment component 4.

[0030] like Figure 1 , Figure 2 , Figure 5 As shown, the surface detection component 3 includes a movable frame 31, a telescopic member 32, and a drive motor 33. The movable frame 31 is located inside the inner cavity 12, and the drive motor 33 is located at the top of the top shell 13. The fixed end of the drive motor 33 is fixedly connected to the top shell 13, and the output end of the drive motor 33 is located inside the inner cavity 12. The output end of the drive motor 33 is fixedly connected to the movable frame 31. One end of the movable frame 31 is provided with a telescopic member 32, and one end of the telescopic member 32 is fixedly connected to the movable frame 31. The other end of the telescopic member 32 is provided with a clamping member 34. The inner wall of the movable frame 31 is provided with a laser emitting unit 35.

[0031] Specifically, the movable frame 31 is located inside the inner cavity 12 and is slidably connected to the inner wall of the inner cavity 12. The drive motor 33 serves as the power source to control the up-and-down movement of the movable frame 31. The clamping member 34 is used to cooperate with the workpiece to prevent the product from shifting. The clamping member 34 is connected to the movable frame 31 through the telescopic member 32. Thus, when the movable frame 31 moves, it drives the telescopic member 32 to move, and the telescopic member 32 drives the clamping member 34 to move. The clamping member 34 is equipped with a laser emitting unit 35, which is used to detect the wear of the heated surface of the workpiece. According to the near-infrared or visible light band, when the pit is irradiated, a shadow area or abrupt change in the reflected light path will appear, thereby judging the wear of the heated surface of the workpiece. Finally, based on the combustion time of the combustion component 2, the temperature of the inner cavity 12, the heat insulation effect of the workpiece, and the wear of the heated surface of the workpiece, the overall strength of the workpiece is obtained. In conjunction with the movement of the movable frame 31, the overall surface inspection of the workpiece is achieved.

[0032] like Figures 1-7 As shown, the temperature sensing cooling component 5 includes a cooling pipe 51, a main semiconductor 52, and a secondary semiconductor 53. The cooling pipe 51 is located on the outer wall of the bottom frame 11 and is fixedly connected to the bottom frame 11. The input end of the cooling pipe 51 is provided with an outer tube 54, and an inner tube 55 is provided inside the outer tube 54. An electromagnetic coil 57 is provided between the outer tube 54 and the inner tube 55. The inner tube 55 is made of nickel. The end of the outer tube 54 away from the cooling pipe 51 is provided with an input pipe 56. The input pipe 56, the inner tube 55, and the cooling pipe 51 are connected. The main semiconductor 52 is located on the side of the clamping member 34 away from the bottom frame 11. An installation cavity is opened in the movable frame 31, and the secondary semiconductor 53 is located in the installation cavity.

[0033] Specifically, the temperature sensing cooling component 5 is used to cool the device and product after high-temperature detection. The cooling pipe 51 is located on the outer wall of the bottom frame 11. When coolant flows through the cooling pipe 51, it cools the device. The cooling efficiency of the cooling pipe 51 is controlled by the flow rate, which is controlled by the orifice diameter of the inner tube 55. Then, the input pipe 56 connects to the external cooling pipe, allowing external coolant to enter the inner tube 55 through the input pipe 56, and then enter the cooling pipe 51 through the inner tube 55. A closed loop is formed between the main semiconductor 52 and the secondary semiconductor 53. After high-temperature detection, the main semiconductor 52 is located outside the device, and the secondary semiconductor 53 is located inside the inner cavity 12. A significant temperature difference between them causes charge accumulation in the loop, generating voltage and current. The current flows to the electromagnetic coil 57, causing the electromagnetic coil 57 to generate magnetic force. Because the inner tube 55 is made of nickel, the generated magnetic force affects the inner tube 55, causing the inner tube 55 to... The shrinkage towards the central axis lowers the inner hole, ultimately reducing the flow rate of the coolant. As the temperature of the inner cavity 12 gradually decreases with the absorption of coolant, the temperature between the main semiconductor 52 and the secondary semiconductor 53 becomes smaller, the generated current also decreases, the magnetic force generated by the electromagnetic coil 57 also decreases, and consequently the diameter of the inner tube 55 increases, accelerating the flow rate of the coolant. This ensures that the cooling efficiency of the temperature sensing cooling component 5 increases rapidly immediately after the detection ends, preventing damage to the rapid cooling device or workpiece. During the detection process, because the main semiconductor 52 is located at the end of the workpiece furthest from the inner cavity 12, and the secondary semiconductor 53 is located at the end of the workpiece close to the inner cavity 12, a temperature difference is generated between the main semiconductor 52 and the secondary semiconductor 53 due to the workpiece obstruction. Finally, since the temperature inside the inner cavity 12 is the set heating value, the temperature of the two different spaces can be determined based on the size of the temperature difference, thereby determining the heat insulation efficiency of the workpiece. That is, the larger the current, the better the heat insulation efficiency, and vice versa.

[0034] like Figure 3 , Figure 4 As shown, the exhaust gas treatment component 4 includes a filling column 41 and an air intake pipe 42. The bottom of the top shell 13 has four air inlets 131, which are connected to the inner cavity 12. The top of the top shell 13 has an air outlet 132. The air intake pipe 42 is located at the top of the top shell 13 and is connected to the air outlet 132. The filling column 41 is located inside the top shell 13 and is fixedly connected to the inside of the top shell 13. The filling column 41 is filled with activated carbon.

[0035] Specifically, during the high-temperature testing process, the continuous high-temperature combustion of the fireproof rock wool board generates a large amount of waste gas and toxic gas. As a result, the gas in the inner cavity 12 cannot be directly discharged and needs to be collected. The suction pipe 42 in the waste gas treatment component 4 is connected to the external gas pipeline. The external gas pipeline provides suction, so the gas in the inner cavity 12 will enter the outer shell through the air inlet 131 and then pass through the filling column 41. Most of the fine particles and toxic gases in the gas will be absorbed by the filling column 41. However, since the gas is generated during high-temperature testing, the gas temperature is also higher than normal, so it needs to be treated. During the subsequent treatment, the inner wall of the pipe or the filter material will be damaged.

[0036] like Figure 4 As shown, the input pipe 56 penetrates the top shell 13 and is located between the filling column 41 and the air inlet 131.

[0037] Specifically, there are two input pipes 56, both of which laterally penetrate the outer casing. The ends of the two input pipes 56 furthest from the outer tube 54 are not connected to each other, while the ends of the two input pipes 56 closest to the outer tube 54 are connected to each other and also connected to the inner tube 55. Then, one of the two input pipes 56 is connected to an external coolant pipe. During high-temperature testing, the inner cavity 12 continuously sprays high-temperature flames, causing the secondary semiconductor 53 to reach its highest temperature state, i.e., the maximum temperature difference with the primary semiconductor 52, resulting in the maximum current. This ultimately causes the inner tube 55 to shrink to its minimum state, thus preventing the cooling pipe 51 from achieving the most basic cooling effect. Furthermore, since there are two input pipes 56, when connected... The coolant flowing through the input pipe 56 connected to the external coolant pipe first passes through the inner wall of the outer casing to cool the high-temperature gas inside the casing. Then, it flows to the branch point located at the connection of the inner pipe 55. At this time, if the device is performing high-temperature detection, the inner pipe 55 will be blocked, and the coolant cannot flow to the cooling pipe 51. Instead, the coolant flows to the other input pipe 56. After the high-temperature detection is completed, the temperature inside the inner cavity 12 will slowly decrease, which will lead to a decrease in the value of the current generated, an expansion of the diameter of the inner pipe 55, and an increase in the coolant flow rate, thereby cooling the inner cavity 12. As the temperature of the inner cavity 12 decreases, the cooling efficiency of its top shell 13 will decrease, and the cooling efficiency of the inner cavity 12 will increase.

[0038] like Figure 2 , Figure 3 As shown, the combustion assembly 2 includes a nozzle 21 and a delivery pipe 22. The nozzle 21 is located on the inner wall of the inner cavity 12, and the delivery pipe 22 is located on the outer wall of the bottom frame 11. The delivery pipe 22 is connected to the nozzle 21.

[0039] Specifically, the combustion assembly 2 is used to burn the workpiece at high temperature. The output end of the nozzle 21 is connected to the inside of the inner cavity 12. The input end of the nozzle 21 is connected to the delivery pipe 22. One end of the delivery pipe 22 is connected to the external fuel pipe to deliver fuel to the nozzle 21. There are three nozzles 21, which are arranged vertically at equal intervals.

[0040] like Figure 8 As shown, the bottom of the outer casing assembly 1 is provided with a fixing component 6. The fixing component 6 includes a guide rail 61 and a placement base 62. One end of the guide rail 61 is fixedly connected to the bottom end of the base frame 11, and the other end of the guide rail 61 is provided with a placement base 62. The bottom end of the placement base 62 is provided with a pulley 63, which cooperates with the guide rail 61.

[0041] Specifically, the fixing component 6 is used to place the workpiece. The top of the placement base 62 is provided with a groove that cooperates with the bottom of the workpiece. The bottom of the placement base 62 is provided with a pulley 63 to prevent the base 62 from moving on the guide rail 61 through the pulley 63, thereby making the workpiece mesh with the inner cavity 12 to form a closed space.

[0042] Working principle: Before testing, the workpiece is placed on the base frame 62 and restrained by the clamping member 34. The workpiece is then moved into the inner cavity 12, forming a sealed space for high-temperature testing. The delivery pipe 22 delivers fuel to the nozzle 21, where it is burned at high temperature. At this time, the temperature inside the inner cavity 12 rises rapidly, creating a large temperature difference with the outside temperature. A current is generated between the main semiconductor 52 and the secondary semiconductor 53, and this current is at its maximum value. The current generated by the main semiconductor 52 and the secondary semiconductor 53 is used to energize the electromagnetic coil 57, generating magnetic force, which in turn controls the inner tube 55 to contract. The coolant flows through the input pipe 56 to the branch port. When the inner tube 55 is blocked, the coolant cannot flow to the cooling pipe 51 and instead flows to another input pipe. In the detection process, only the exhaust gas of the top shell 13 is cooled, while the temperature of the inner cavity 12 is not cooled. During the high-temperature detection, when the near-infrared or visible light band of the laser emitting unit 35 irradiates the pit, a shadow area or abrupt change in the reflected light path will appear, thereby judging the wear of the workpiece's heated surface. Based on the combustion time of the combustion component 2, the temperature of the inner cavity 12, the heat insulation effect of the workpiece, and the wear of the heated surface of the workpiece, the overall strength of the workpiece is obtained. After the high-temperature detection is completed, the temperature inside the inner cavity 12 will slowly decrease, which will lead to a decrease in the value of the current generated, an expansion of the diameter of the inner tube 55, and an increase in the flow rate of the coolant, thereby cooling the inner cavity 12. As the temperature of the inner cavity 12 decreases, the cooling efficiency of the top shell 13 will decrease, while the cooling efficiency of the inner cavity 12 will increase.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
