Description

Technical Field

[0001] This utility model relates to the technical field of refractory material testing boxes, and in particular to a refractory material testing box. Background Technology

[0002] In the field of refractory material performance testing, pressure testing is a crucial step in evaluating the material's mechanical properties. Current refractory material pressure testing equipment often employs a simple box-type structure, with the testing platform fixed inside the box. A drive mechanism moves the testing block to apply pressure to the material. However, this type of equipment has significant drawbacks: after testing, debris from material breakage tends to accumulate at the bottom of the testing box, requiring manual opening and cleaning. This not only increases the operational process and reduces testing efficiency but may also affect the accuracy of subsequent tests due to incomplete cleaning. In the performance testing of refractory materials under high-temperature conditions, temperature sensors and heating rods are directly exposed in the testing space. Material fragments generated during the testing process can easily cause impact damage to them, shortening the service life of the components.

[0003] Therefore, it is necessary to provide a refractory material testing box to solve the above-mentioned technical problems. Utility Model Content

[0004] This invention provides a refractory material testing box, which solves the problems in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a refractory material testing box, including a testing box body. A conical material drop frame is installed through the bottom of the testing box body, forming a vertically connected structure. A sealing cover is adapted to one end of the conical material drop frame. The sealing cover cooperates with the material drop frame to achieve sealing and opening / closing, facilitating the collection and cleaning of debris. A fixing rod is installed on the inner wall of the testing box body, and a testing platform is installed at the top of the fixing rod. The fixing rod provides stable support for the testing platform, so that the testing platform is at a suitable height inside the testing box body. A driving cylinder is installed on the top surface of the testing box body. A testing block is installed at the output end of the driving cylinder. A pressure sensor is connected between the testing block and the driving cylinder. When the driving cylinder works, the output end drives the testing block to move and pressurize the refractory material on the testing platform. The pressure sensor monitors the pressure applied by the testing block in real time. At the same time, the debris generated during testing falls into the conical material drop frame. The sealing cover can prevent debris from falling out when not being cleaned. Preferably, a heating rod is installed on the inner wall of the testing chamber, which directly heats the internal space of the testing chamber. A second grid protective cover is installed on the inner wall of the testing chamber outside the heating rod. The second grid protective cover is fixed to the inner wall of the chamber through fixing holes on its surface. The grid mesh inside the second grid protective cover can prevent material fragments generated during the testing process from hitting the heating rod, thus providing protection. A temperature sensor is installed on the inner wall of the testing chamber, which is used to monitor the temperature inside the chamber in real time. A first grid protective cover is installed on its outer side, which is also fixed through fixing holes on its surface. The grid mesh inside the first grid protective cover prevents fragments from damaging the temperature sensor without affecting the monitoring accuracy of the temperature sensor. Preferably, a vibrator is installed on the outer surface of the conical material dropping frame. The vibration generated by the vibrator when it is working is transmitted to the conical material dropping frame, which can assist the falling of the broken material in the frame, prevent the broken material from sticking to the inner wall of the dropping frame and causing accumulation, and ensure smooth material dropping. Preferably, a sealing door is movably installed on the outer surface of the testing chamber body. The sealing door can be opened and closed flexibly. When closed, it can form a closed testing space. A transparent observation window is installed on the sealing door, allowing operators to view the testing situation inside the chamber in real time without opening the sealing door, thus ensuring the stability of the testing environment. Preferably, the bottom of the testing box body is equipped with multiple support legs, and the multiple support legs are equally spaced at the four corners of the bottom of the testing box body. The support legs support the entire testing box body, keeping the testing box body at a certain distance from the ground. This not only prevents the bottom from getting damp, but also ensures the overall stability of the equipment during the testing process and prevents shaking from affecting the testing accuracy. Preferably, a controller is installed on the outer surface of the detection box body. The controller is electrically connected to components such as the drive cylinder, pressure sensor, heating rod, and temperature sensor. The controller can set detection parameters and control the working status of each component to achieve automated control of the detection process.

[0006] Compared with related technologies, the refractory material testing box provided by this utility model has the following beneficial effects: Compared with existing technologies, the conical material feeding frame can automatically collect material debris generated during the testing process. Combined with the sealing cover, it facilitates centralized cleaning, eliminating the need for manual opening of the box to clean debris, reducing operation procedures, improving testing efficiency, and avoiding the impact of debris accumulation on the accuracy of subsequent tests.

[0007] Compared with existing technologies, the first and second grid protective covers can effectively protect the temperature sensor and the heating rod respectively, blocking the direct impact of material fragments, reducing the risk of component damage, and extending the service life of the temperature sensor and the heating rod.

[0008] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0012] Please refer to the following: Figure 1-4A refractory material testing box includes a testing box body 1. A conical discharge frame 8 is welded through to the bottom of the testing box body 1, and the connection between the two is sealed with sealant to ensure that debris does not leak from the connection. The outer wall of the discharge end of the conical discharge frame 8 has external threads, and the inner wall of the sealing cover 7 has internal threads. The sealing cover 7 is installed at the discharge end of the conical discharge frame 8 through threaded fitting. This threaded connection method facilitates the quick opening and closing of the sealing cover 7, enabling convenient cleaning of debris. A fixing rod 14 is bolted to the inner wall of the testing box body 1. The top of the fixing rod 14 is welded to the bottom of the testing platform 13. The installation sequence is to first fix the fixing rod 14, and then weld the testing platform 13 to the top of the fixing rod 14. The fixing rod 14 provides stable support for the testing platform 13, placing the testing platform 13 in the middle position inside the testing box body 1, ensuring uniform force when the testing block 10 is pressed. A drive cylinder 3 is bolted to the top surface of the test chamber body 1. The piston rod at the output end of the drive cylinder 3 is connected to the top of the test block 10 via a flange. The two ends of the pressure sensor 19 are connected to the top of the test block 10 and the piston rod at the output end of the drive cylinder 3 via flanges, respectively. The installation sequence is as follows: after the drive cylinder 3 is fixed, the pressure sensor 19 and the test block 10 are connected sequentially. When the drive cylinder 3 is working, the piston rod extends and retracts, causing the test block 10 to move up and down, applying pressure to the refractory material on the test platform 13. The pressure sensor 19 detects the pressure value in real time and provides feedback, achieving precise pressure control. The debris generated during testing falls into the conical discharge frame 8 under gravity. The inclined structure of the conical discharge frame 8 guides the debris to gather towards the discharge end. The sealing cover 7 prevents debris from falling out in a non-cleaned state through threaded sealing, eliminating the need for manual opening and cleaning, improving testing efficiency, and preventing debris accumulation from affecting subsequent testing accuracy. Example

[0013] Please refer to the following: Figure 1-4A heating rod 15 is bolted to the inner wall of the testing chamber body 1. The wiring terminals of the heating rod 15 pass through the wall of the testing chamber body 1 and are sealed to ensure that the high-temperature environment inside the chamber does not affect the external circuitry. The inner wall of the testing chamber body 1 is located outside the heating rod 15. The second grid protective cover 16 is fixed to the inner wall of the chamber by bolts passing through the fixing holes 17 on its surface. The installation sequence is to install the heating rod 15 first, then install the second grid protective cover 16. The second grid protective cover 16 completely covers the heating rod 15. The grid mesh 18 inside is made of high-temperature resistant metal material, and its mesh size ensures normal heat transfer while preventing material fragments from impacting the heating rod 15. A temperature sensor 12 is bolted to the inner wall of the testing chamber body 1. The sensing end of the temperature sensor 12 faces the inside of the testing chamber, and its wiring terminals are also sealed through the chamber wall. The temperature sensor 12 is secured to the inner wall of the chamber by bolts passing through the fixing holes 17 on the surface of the first grid protective cover 11. The installation sequence is to install the temperature sensor 12 first, followed by the first grid protective cover 11. The mesh size of the grid 18 of the first grid protective cover 11 does not affect the temperature sensor 12's detection of the temperature inside the chamber. When the heating rod 15 is working, it heats the inside of the chamber. The temperature sensor 12 monitors the temperature in real time and feeds it back to the controller 4, achieving precise temperature control. The first grid protective cover 11 and the second grid protective cover 16 provide effective protection for the temperature sensor 12 and the heating rod 15, respectively, preventing damage from material fragments, extending the service life of the components, and ensuring the stability of the high-temperature detection environment. Example

[0014] Please refer to the following: Figure 1-4 A vibrator 6 is bolted to the outer surface of the conical discharge frame 8. The vibrating end of the vibrator 6 is tightly fitted to the outer wall of the discharge frame. The installation sequence is that the vibrator 6 is fixed after the conical discharge frame 8 is installed. When there is debris stuck inside the conical discharge frame 8, the vibrator 6 is activated to generate high-frequency vibration. The vibration is transmitted through the outer wall of the discharge frame to the entire discharge frame, causing the stuck debris to detach from the inner wall of the discharge frame under the action of vibration. This helps the debris to gather towards the discharge end, ensuring that the debris can be discharged smoothly and further improving the thoroughness of debris cleaning. Example

[0015] Please refer to the following: Figure 1-4The outer surface of the testing chamber body 1 has hinges at the top and bottom of the door frame. The sealed door 2 is movably connected to the testing chamber body 1 via the hinges. The hinges adopt a hinge structure, allowing the sealed door 2 to rotate flexibly to open and close. The edge of the sealed door 2 has a sealing strip, which fits tightly against the door frame of the testing chamber body 1 when closed, forming a closed testing space and reducing heat loss and external environmental interference. A transparent observation window 9 is installed on the sealed door 2 by embedding. The observation window is made of high-temperature resistant glass. The installation sequence is to first install the hinges and the sealed door 2, and then embed the transparent observation window 9. The operator can observe the testing situation inside the chamber in real time through the transparent observation window 9 without opening the sealed door 2, ensuring the stability of the testing environment and avoiding the impact of temperature fluctuations caused by opening the door on the test results. Example

[0016] Please refer to the following: Figure 1-4 At the four corners of the bottom of the testing box body 1, the connecting parts of the support legs 5 are first welded and fixed, and then the support legs 5 are fixed to the connecting parts with bolts. Multiple support legs 5 are distributed at equal intervals. The installation sequence is to install the support legs 5 after the main structure of the testing box body 1 is completed. The support legs 5 are made of high-strength metal material and have anti-slip pads on the bottom. The support legs 5 raise the testing box body 1, so that the discharge end of the conical material feeding frame 8 is away from the ground, which facilitates the cleaning of broken materials and prevents the bottom of the testing box body 1 from getting damp. The anti-slip pads increase the friction with the ground, ensuring the overall stability of the equipment during the testing process and preventing the pressure testing accuracy from being affected by the shaking of the equipment. Example

[0017] Please refer to the following: Figure 1-4 The outer surface of the testing chamber body 1 is bolted to a controller 4. The controller 4 is positioned for easy operation. Its internal circuitry is electrically connected to components such as the drive cylinder 3, pressure sensor 19, heating rod 15, temperature sensor 12, and vibrator 6 via wires. The wires are sealed and insulated when passing through the wall of the testing chamber body 1. The installation sequence is as follows: after each functional component is installed, connect the wires and fix the controller 4. The controller 4 receives feedback signals from the pressure sensor 19 and temperature sensor 12, and controls the pressure output of the drive cylinder 3, the heating temperature of the heating rod 15, and the working state of the vibrator 6 according to preset parameters, achieving automated control of the testing process. All components work collaboratively under the coordination of the controller 4, ensuring the accuracy, efficiency, and safety of the testing process. Ultimately, this achieves performance testing of refractory materials under different pressure and temperature environments, solving the problems of inconvenient cleaning and easy component damage in existing technologies.

[0018] It should be noted that the control circuit of controller 4 can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0019] The working principle of the refractory material testing box provided by this utility model is as follows: Before testing, open the sealed door 2 on the outside of the testing chamber body 1 and place the refractory material to be tested on the testing platform 13 (the testing platform 13 is fixed to the inner wall of the testing chamber body 1 by a fixing rod 14 to ensure stability during testing). After closing the sealed door 2, start the equipment through the controller 4 on the outside of the testing chamber body 1. If performance testing under high temperature conditions is required, the controller 4 controls the heating rod 15 to start working and heat the inner cavity of the testing chamber body 1. At the same time, the temperature sensor 12 monitors the temperature inside the cavity in real time. The first grid protective cover 11 on its outside, through the fixing structure of the grid mesh 18 and the fixing holes 17, prevents material fragments from hitting the temperature sensor 12 without affecting the temperature sensing. Similarly, the second grid protective cover 16 on the outside of the heating rod 15 is protected by the grid mesh 18 to prevent fragments from damaging the heating rod 15 during heating or when the material breaks. Once the temperature inside the testing chamber 1 reaches the required level, the controller 4 activates the drive cylinder 3. The output of the drive cylinder 3 moves the testing block 10 toward the refractory material on the testing platform 13 and applies pressure. The pressure sensor 19 between the testing block 10 and the drive cylinder 3 monitors the applied pressure value in real time to ensure accurate acquisition of the testing data. During the pressurization process, the refractory material crushes and produces debris that falls. Since a conical discharge frame 8 is installed through the bottom of the test box body 1 below the test platform 13, the debris slides down the inclined inner wall of the conical discharge frame 8 to the bottom under the action of gravity. If the debris sticks to the inner wall of the discharge frame, the vibrator 6 on the outside of the conical discharge frame 8 can be activated to assist the debris in falling through vibration and prevent accumulation. After the test is completed, the drive cylinder 3 and heating rod 15 are turned off. After the equipment cools down, the sealing cover 7 at one end of the conical discharge frame 8 can be opened to collect and clean up the debris. Throughout the process, the transparent observation window 9 allows real-time observation of the internal testing status, while the support legs 5 ensure the stable placement of the testing box body 1. The coordinated operation of all components enables efficient and safe testing of refractory materials.
