Description

Technical Field

[0001] This utility model relates to the field of materials testing and analysis technology, specifically a box-type resistance furnace for materials composition analysis. Background Technology

[0002] In the field of compositional analysis and performance testing of metallic and inorganic non-metallic materials, it is often necessary to heat-treat material samples before quenching or subjecting them to corrosion reactions in specific liquid environments. By observing the morphological changes and surface characteristics of the samples after exposure to water or acid / alkali test solutions at high temperatures, the composition or performance properties of the material can be indirectly determined. For example, some alloy materials exhibit specific surface crack characteristics after high-temperature quenching, or some materials show characteristic color changes or corrosion morphologies in specific acidic or alkaline environments. These are important bases for material compositional analysis.

[0003] Currently, conventional testing methods typically involve operators heating the test block using a separate box-type resistance furnace. After heating, the test block is removed using clamps and then manually immersed in cooling water or a test solution for reaction observation. This method has the following problems: First, the heating and immersion processes are separated, and there is a time delay between removing the test block from the furnace and immersing it in the liquid. The temperature drop affects the accuracy and consistency of the quenching effect, resulting in poor repeatability of the analysis results. Second, manually handling and transferring high-temperature test blocks poses a significant safety hazard, as operators are prone to burns. Third, the immersion depth of the test block relies on manual visual inspection or experience, making it difficult to quantify precisely. Furthermore, existing equipment lacks automatic detection methods for test block displacement, resulting in inconsistent immersion depths between different batches, which cannot provide accurate data support for subsequent analysis and affects the comparability of analytical results. Fourth, switching between cooling water and test solutions requires manual replacement of containers or pipelines, which is cumbersome, inefficient, and prone to cross-contamination between different liquids. Fifth, some existing equipment uses the same container for reaction waste liquid and cooling water, leading to waste liquid contamination of the cooling water, affecting the cooling effect of the pipeline and the service life of the equipment.

[0004] Therefore, how to design a box-type resistance furnace that can integrate the heating and immersion reaction of the test block, accurately detect displacement, conveniently switch between cooling water and test liquid supply modes, completely isolate waste liquid and cooling water, and has a high degree of automation has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide a box-type resistance furnace for material composition analysis, which has the advantages of integrated sample heating and immersion reaction, accurate displacement detection, convenient switching between dual-mode liquid supply, complete isolation of waste liquid and cooling water, and high degree of automation, thus solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A box-type resistance furnace for material composition analysis includes a support platform, a first tank opened at the upper end of the support platform, a second tank opened at the upper end of the support platform, a support box fixedly connected to the inner wall of the second tank, a control box fixedly connected to the upper end of the support platform, a support block fixedly connected to the upper end of the support platform, a resistance furnace body fixedly connected to the upper end of the support block, a lifting mechanism disposed at the upper end of the support platform, a first mounting block detachably installed at the lifting end of the lifting mechanism, a reaction mechanism disposed in a first through hole, a liquid supply mechanism disposed on the bottom surface of the inner wall of the first tank, a ruler fixedly connected to the upper end of the support platform, and a camera mechanism disposed at the upper end of the support platform; the lower end of the resistance furnace body has a first through hole communicating with the internal cavity of the furnace, the reaction mechanism is disposed on the inner wall of the first through hole, the liquid inlet end of the reaction mechanism is connected to the liquid outlet end of the liquid supply mechanism, the inside of the support box is a cooling water storage cavity, and the liquid extraction end of the liquid supply mechanism is connected to the inside of the support box; The lifting end of the lifting mechanism can move back and forth in the vertical direction, driving the first mounting block to rise and fall synchronously. The first mounting block is used to place the test block to be tested. The first through hole is coaxially aligned with the lifting end of the lifting mechanism, so that the lifting mechanism can drive the test block through the first through hole into the resistance furnace for heating. The camera mechanism is positioned with its camera end facing the ruler and the first mounting block. The ruler has scale lines, and the camera mechanism is used to collect the scale data corresponding to the lifting and lowering of the first mounting block in order to obtain the lifting displacement of the first mounting block. The control box is electrically connected to the lifting mechanism, camera mechanism, and liquid supply mechanism, and is used to control the start-up, shutdown, and operating status of each electrical component.

[0007] Preferably, the lifting mechanism includes a bracket fixedly connected to the upper end of the support platform, a cylinder fixedly connected to the bracket, and a lifting block fixedly connected to the lower end of the cylinder output shaft. The inner walls of the lifting block are provided with grooves extending horizontally along their length on both sides. A first mounting block is slidably disposed between the inner walls of the lifting block. Both sides of the first mounting block are fixedly connected with protrusions. The size and shape of the protrusions are adapted to the grooves. One end of the protrusion is provided with a first screw hole.

[0008] It is worth noting that the groove extends horizontally along the length of the lifting block and forms a sliding fit with the protrusion, allowing the first mounting block to slide horizontally into or out from the end of the lifting block, thus enabling convenient disassembly and assembly. When it is necessary to replace test blocks of different specifications or clean test block residue, the operator only needs to loosen the bolts to pull out the first mounting block as a whole, without disassembling other parts of the lifting mechanism, which facilitates daily maintenance and test block specification switching.

[0009] Preferably, the two end faces of the first mounting block are flush with the two end faces of the lifting block. A second mounting block is provided on each end face of the first mounting block. Two second screw holes are opened through the second mounting block. Bolts are threaded on the inner wall of the second screw holes. The bolts pass through the second screw holes and are threaded onto the inner wall of the first screw holes. The ends of the two second mounting blocks that are close to each other are fitted with the two end faces of the lifting block so as to detachably fix the first mounting block to the lifting block.

[0010] It is worth noting that the fitting and limiting cooperation between the end face of the second mounting block and the lifting block prevents the first mounting block from moving or swaying in the horizontal direction during the lifting process. This ensures that the test block on the first mounting block remains coaxially aligned with the first through hole during the lifting and passing through the first through hole, avoiding collisions and scratches between the test block and the inner wall of the furnace or the inner wall of the fixed cylinder, thus ensuring the stability and safety of the heating and immersion process.

[0011] Preferably, a third groove is formed through the lower part of one end of the first mounting block in a horizontal direction, and a fourth groove is formed through the lower part of both sides of the first mounting block in a vertical direction. The third groove and the two fourth grooves are interconnected and together form a cross-shaped groove. The test block is placed on the bottom surface of the inner wall of the third groove, and the two sides of the test block are respectively attached to the two sides of the inner wall of the third groove. A plurality of second through holes are formed through the bottom surface of the inner wall of the third groove.

[0012] It is worth noting that the cross-shaped trough design provides the test block with stable support from the bottom of the third trough, while also limiting the test block through the inner walls of the third trough on both sides, preventing the test block from tilting or falling off during the lifting and lowering process; the setting of multiple second through holes ensures that the liquid can smoothly enter the interior of the trough from below the test block, so that the bottom and sides of the test block can fully contact the reaction liquid, avoiding the problems of bubble retention or uneven reaction caused by the closed bottom of the trough.

[0013] Preferably, the inner wall of the resistance furnace body is provided with a heating mechanism, which includes two fixed rings fixedly connected to the inner wall of the resistance furnace body at intervals along the axial direction and a resistance wire fixedly connected to one end of the two fixed rings close to each other. The resistance wire is arranged around the outer periphery above the first through hole and is electrically connected to the control box.

[0014] It is worth noting that the resistance wire is positioned on the outer periphery above the first through hole, close to the inner cavity of the resistance furnace. When the test block is driven by the lifting mechanism to pass through the first through hole and enter the inner cavity of the furnace, the test block is precisely located within the annular heating area of ​​the resistance wire, receiving uniform heat radiation. This results in faster heating and a more uniform temperature distribution, effectively avoiding the impact of uneven heating on the test block and subsequent reaction results caused by local overheating or temperature gradients. The two fixing rings are spaced apart along the axial direction, ensuring that the resistance wire maintains a stable axial position within the furnace and that the relative position of the test block and the resistance wire is consistent during each heating.

[0015] Preferably, the camera mechanism includes a horizontal block fixedly connected to the upper end of the support platform, a vertical block fixedly connected to the upper end of the horizontal block, and a camera fixedly connected to the vertical block; the camera's image end is set perpendicularly to the scale surface of the ruler, and the camera is electrically connected to the control box to transmit the acquired scale image data to the control box in order to calculate the lifting displacement of the first mounting block.

[0016] It is worth noting that the camera end is set perpendicular to the scale surface to ensure that the captured scale image is free from perspective distortion. The control box can directly use the image recognition algorithm to call the built-in scale comparison program to automatically read the scale difference before and after the first mounting block is raised and lowered, without the need for manual reading, thus improving the accuracy and efficiency of displacement measurement.

[0017] Preferably, the reaction mechanism includes a fixed cylinder fixedly connected to the inner wall of the first through hole, an inlet pipe and an outlet pipe fixedly connected to the lower end of the fixed cylinder, and a wastewater discharge pipe for discharging waste liquid. The inlet pipe is provided with a first valve body for controlling its on / off state, and the outlet pipe is provided with a second valve body for controlling its on / off state. The inlet end of the inlet pipe is connected to the outlet end of the liquid supply mechanism, the outlet end of the outlet pipe is connected to the inlet end of the wastewater discharge pipe, the outlet end of the wastewater discharge pipe extends toward the outside of the carrier box, and the wastewater discharge pipe is not connected to the inside of the carrier box.

[0018] It is worth noting that the fixed cylinder, as the reaction vessel, is directly located below the resistance furnace body, allowing the test block to be immediately lowered into the liquid inside the fixed cylinder by the lifting mechanism after heating. The time delay between the heating and immersion stages is minimized, effectively ensuring the consistency of quenching temperature conditions. The wastewater drain pipe is not connected to the inside of the carrier box, ensuring that the waste liquid generated by the reaction is discharged directly to the outside through the liquid outlet pipe and the wastewater drain pipe, without entering the carrier box and contaminating the cooling water in the cooling water storage chamber. This ensures the cleanliness of the cooling water and thus ensures the long-term stability of the cooling effect of the cooling water on the pipeline.

[0019] Preferably, the liquid supply mechanism connected to the inlet pipe includes a pump body and a test liquid storage tank fixedly connected to the bottom surface of the inner wall of the first tank; the pump body is fixedly connected to a water pumping pipe, the water pumping pipe passes through the outer wall of the carrier box and extends to the cooling water storage chamber inside the carrier box; the pump body is fixedly connected to an outlet pipe, the outlet pipe is fixedly connected to a first connecting pipe, and the outlet of the first connecting pipe is connected to the inlet pipe.

[0020] It is worth noting that by integrating the pump body and the test fluid storage tank into the first tank, the supply pipeline and the support platform form a compact overall structure, reducing the number and length of external pipelines, lowering the risk of pipeline leakage, and making the overall appearance of the equipment simple, which is convenient for handling and on-site layout.

[0021] Preferably, a second connecting pipe is fixedly connected to the pumping pipe, and the pumping end of the second connecting pipe is connected to the outlet end of the detection liquid storage tank; a third valve body for controlling its on / off state is provided on the second connecting pipe, and a fourth valve body for controlling its on / off state is provided on the pumping pipe, the fourth valve body being located on the pumping pipe between the second connecting pipe and the carrier box; the first valve body, the second valve body, the third valve body, and the fourth valve body are all electrically connected to the control box.

[0022] Preferably, the third valve body and the fourth valve body cooperate to form a dual-path independent liquid supply structure: when the third valve body is closed and the fourth valve body is opened, the pump body, the water suction pipe, the water outlet pipe, the first connecting pipe, the liquid inlet pipe and the carrier box form a cooling water supply channel for supplying cooling water to the fixed cylinder; when the fourth valve body is closed and the third valve body is opened, the pump body, the second connecting pipe, the water outlet pipe, the first connecting pipe, the liquid inlet pipe and the detection liquid temporary storage tank form a detection liquid supply channel for supplying detection liquid to the fixed cylinder.

[0023] It is worth noting that the dual-channel independent liquid supply structure can switch between cooling water and test liquid supply by cooperating with the mutual exclusion switches of the two valve bodies, without the need to manually replace the pipeline or connect different liquid supply containers; the two liquid supply channels share the pump body and outlet pipe, which simplifies the structure and saves manufacturing costs and installation space; the test liquid temporary storage tank is set up independently and is completely physically isolated from the cooling water storage chamber in the carrier tank, avoiding cross-contamination between the two liquids and ensuring the accuracy of the test results.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets the resistance furnace body on the upper part of the support platform and sets the reaction mechanism directly below it. With the help of the first mounting block that can be lifted vertically, the test block can be directly driven by the lifting mechanism to pass through the first through hole and immerse into the liquid in the fixed cylinder after heating. This solves the problem of temperature drop and poor repeatability of analysis results caused by the separation of heating and immersion in the liquid in the prior art. It realizes the integrated operation of test block heating and immersion reaction and ensures the consistency of quenching temperature conditions. 2. This utility model solves the problem in the prior art that the immersion depth relies on manual visual inspection and is difficult to quantify accurately by setting up a ruler and a camera mechanism and using the camera to collect the corresponding scale data before and after the first mounting block is raised and lowered. It realizes the automatic and accurate measurement of the displacement of the test block and provides reliable data support for subsequent analysis. 3. By setting up a dual-path independent liquid supply structure, the present invention can conveniently switch between the cooling water supply channel and the detection liquid supply channel through the cooperation of the third valve body and the fourth valve body. This solves the problem that the switching of cooling water and detection liquid requires manual replacement of pipelines, which is cumbersome and prone to cross-contamination in the prior art, thus improving detection efficiency and ease of operation. 4. This utility model solves the problem in the prior art that the waste liquid and cooling water share a container, resulting in the cooling water being contaminated and the cooling effect of the pipeline decreasing. This is achieved by setting the inside of the carrier box as a cooling water storage chamber and setting the waste water discharge pipe to be independent from the inside of the carrier box, so that the reaction waste liquid is discharged to the outside through an independent waste water discharge pipe. This ensures the long-term cleanliness of the cooling water and the stability of the pipeline cooling effect. 5. This utility model solves the safety hazards of transferring and clamping high-temperature test blocks in the prior art by opening a third and fourth groove on the first mounting block and using the inner wall of the third groove to stably limit the two sides of the test block. With the setting of multiple second through holes, it ensures that the liquid is in full contact with the test block while preventing the test block from tilting or falling off during the lifting process. This improves the safety of operation. Attached Figure Description

[0031] In this embodiment, specifically, a third groove 26 is horizontally opened through the lower part of one end of the first mounting block 10, and a fourth groove 27 is vertically opened through both sides of the first mounting block 10.

A high-temperature resistant heat-insulating gasket is provided between the fixed cylinder 14 and the resistance furnace body 12, and the outer wall of the fixed cylinder 14 is covered with heat-insulating material.

[0036] In this embodiment, specifically, the liquid supply mechanism connected to the liquid inlet pipe 15 includes a pump body 31 fixedly connected to the bottom surface of the inner wall of the first tank 2 and a detection liquid storage tank 35; the pump body 31 is fixedly connected to a water pumping pipe 32 at the pumping end, the water pumping end of the water pumping pipe 32 passes through the outer wall of the carrier box 4 and extends to the cooling water storage chamber inside the carrier box 4; the pump body 31 is fixedly connected to a water outlet pipe 33 at the outlet end, the water outlet end of the water outlet pipe 33 is fixedly connected to a first connecting pipe 34, and the outlet end of the first connecting pipe 34 is connected to the liquid inlet pipe 15.

[0037] In this embodiment, specifically, a second connecting pipe 36 is fixedly connected to the water pumping pipe 32, and the liquid pumping end of the second connecting pipe 36 is connected to the liquid outlet end of the detection liquid storage tank 35; a third valve body 37 for controlling its on / off state is provided on the second connecting pipe 36, and a fourth valve body 38 for controlling its on / off state is provided on the water pumping pipe 32, and the fourth valve body 38 is located on the pipeline of the water pumping pipe 32 between the second connecting pipe 36 and the carrier box 4; the first valve body 16, the second valve body 18, the third valve body 37, and the fourth valve body 38 are all electrically connected to the control box 5.

[0038] In this embodiment, specifically, the third valve body 37 and the fourth valve body 38 cooperate to form a dual-path independent liquid supply structure: when the third valve body 37 is closed and the fourth valve body 38 is opened, the pump body 31, the water suction pipe 32, the water outlet pipe 33, the first connecting pipe 34, the liquid inlet pipe 15 and the carrier box 4 form a cooling water supply channel for supplying cooling water to the fixed cylinder 14; when the fourth valve body 38 is closed and the third valve body 37 is opened, the pump body 31, the second connecting pipe 36, the water outlet pipe 33, the first connecting pipe 34, the liquid inlet pipe 15 and the detection liquid temporary storage box 35 form a detection liquid supply channel for supplying detection liquid to the fixed cylinder 14.

[0039] Working principle: When in use, the operator first sets the heating temperature, heating time and lifting stroke of the cylinder 902 of the resistance furnace body 12 through the control box 5. The test block 28 to be tested is placed in the cross-shaped groove of the first mounting block 10. The bottom surface of the test block 28 is in contact with the bottom surface of the inner wall of the third groove 26, and the two sides of the test block 28 are respectively in contact with the two sides of the inner wall of the third groove 26 to complete the limiting and fixing. After the test block 28 is placed, the first mounting block 10 is installed onto the lifting block 903. Specifically, the protrusions 21 on both sides of the first mounting block 10 are aligned with the grooves 904 on both sides of the inner wall of the lifting block 903, and pushed horizontally along the length of the groove 904 so that the protrusions 21 slide into the groove 904. When the two end faces of the first mounting block 10 are flush with the two end faces of the lifting block 903, the installation is in place. At this time, the two second mounting blocks 23 are attached to the two end faces of the first mounting block 10, and four bolts 25 are passed through the four second screw holes 24 on the two second mounting blocks 23. The bolts 25 are screwed into the first screw holes 22 at the end of the protrusions 21 and tightened. After tightening, the ends of the two second mounting blocks 23 that are close to each other are tightly attached to the two end faces of the lifting block 903. The protrusions 21 are locked in the groove 904, and the first mounting block 10 is detachably fixed to the lifting block 903, completing the limiting installation of the first mounting block 10. Thus, the preparation work before testing is completed. At the start of the test, the control box 5 controls the cylinder 902 to drive the lifting block 903 to move upward, which in turn drives the first mounting block 10 and the test block 28 through the first through hole 13 into the inside of the resistance furnace body 12. Since the first through hole 13 and the lifting block 903 are coaxially aligned, and the first mounting block 10 does not move horizontally after being limited by the second mounting block 23 and the end face of the lifting block 903, the test block 28 will not scrape against the hole wall during the process of passing through the first through hole 13. After the test block 28 enters the furnace cavity, it is located exactly in the annular heating area of ​​the resistance wire 20. The control box 5 starts the resistance wire 20 to heat the test block 28. During the heating process, the camera 803 collects the initial scale position data of the first mounting block 10 on the ruler 7 in real time and transmits it to the control box 5. After heating is completed, the operator selects the liquid supply mode through the control box 5 according to the testing requirements. If the cooling water quenching test is to be performed, the control box 5 closes the third valve body 37 and opens the fourth valve body 38 and the first valve body 16, starts the pump body 31, and the pump body 31 draws cooling water from the cooling water storage chamber in the bearing box 4 through the water pumping pipe 32, and injects it into the fixed cylinder 14 through the water outlet pipe 33, the first connecting pipe 34 and the liquid inlet pipe 15. When the liquid level reaches the preset height, the liquid injection stops. If a corrosion reaction test of the test liquid is to be performed, the control box 5 closes the fourth valve body 38 and opens the third valve body 37 and the first valve body 16. The pump body 31 draws the test liquid from the test liquid storage tank 35 through the second connecting pipe 36, and injects it into the fixed cylinder 14 through the water outlet pipe 33, the first connecting pipe 34 and the liquid inlet pipe 15. During this process, the cooling water storage chamber inside the carrier box 4 is only used to store cooling water to cool the pipeline, and is completely isolated from the test liquid and the reaction waste liquid. After the liquid supply is completed, the control box 5 controls the cylinder 902 to drive the lifting block 903 to move downward, so that the heated test block 28 passes through the first through hole 13 and is immersed in the cooling water or test liquid in the fixed cylinder 14. The camera 803 collects the real-time scale position data of the first mounting block 10 on the ruler 7 and transmits it to the control box 5. The control box 5 calculates the scale difference before and after the lifting and lowering through the image recognition algorithm to obtain the precise immersion depth of the test block 28. The operator observes the reaction state of the test block 28 in the liquid through the external camera device and records the morphological changes within a specified time. After the test is completed, the control box 5 controls the cylinder 902 to lift and reset the first mounting block 10, close the first valve body 16, open the second valve body 18, and discharge the reaction waste liquid in the fixed cylinder 14 directly to the outside through the liquid outlet pipe 17 and the wastewater drain pipe 11. The waste liquid does not enter the interior of the carrier box 4 at all, ensuring the cleanliness of the cooling water in the carrier box 4. The test block 28 on the first mounting block 10 is taken out for analysis and recording, thus completing a complete material composition analysis and testing process.
