Description
Technical Field
[0001] The utility model relates to the technical field of ore detection, in particular to a burning experimental device. Background Art
[0002] After the ore is mined, the staff needs to judge the quality of the ore. When conducting a burning experiment on the ore, the staff will weigh multiple ores and put them into different crucibles, use a weighing instrument to weigh the ore, and record the weight of the ore before burning in turn. To facilitate the removal of the crucible, the staff will place the crucible on a crucible stand so that multiple crucibles can be taken at one time, and then the crucible and the crucible stand are placed in the calcining furnace together to burn the ore at high temperature. After the high-temperature burning is completed, the staff will place the crucible and the crucible stand into the external environment. When the temperature of the two drops to a suitable temperature in the placement box, the weighing instrument is used to weigh the ore after burning again, and the weight of the ore after burning is recorded in turn. By comparing the weight data of the ore before and after burning, the burning reduction result of the ore is calculated.
[0003] However, after the crucible is placed in the crucible stand, the circumference of the crucible will abut against the limiting holes of the crucible stand, and it is easy to break during high-temperature calcination, affecting the stability of the calcination experiment. After the staff takes the crucible and the crucible stand out from the calcination furnace, the ore will absorb moisture from the surrounding environment when the temperature is below 200°C, affecting the accuracy of the test results. Because the temperature of the crucible stand is too high, the staff cannot implement the temperature detection. When weighing each batch of calcined ore, it cannot be kept at the same temperature, resulting in the inability to guarantee the consistency of the results of each batch of calcination experiments.
[0004] Therefore, a burning experiment device is needed urgently to solve the above-mentioned technical problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0031] like Figures 1 to 3 As shown in , the utility model provides a burning test device, which is used to detect the weight of the ore before and after burning after a high-temperature burning test, so as to detect the burn-off amount of the ore during burning. The burning test device includes a calcining furnace, a weighing instrument, a crucible and an auxiliary component, and the auxiliary component includes a crucible stand 1 and a placement box 2. The crucible stand 1 is used to place the crucible. The placement box 2 is provided on the one hand to ensure the safety of the working environment of the staff, to prevent the staff from touching the crucible and the crucible stand 1 after burning, causing burns. On the other hand, it can prevent the moisture in the surrounding environment of the ore from entering the ore during the cooling process, thereby affecting the weighing result of the ore.
[0032] The crucible stand 1 includes a limiting plate 11, a lifting plate 12 and a connecting rod 13, the lifting plate 12 and the limiting plate 11 are arranged in sequence along the height direction, the connecting rod 13 is connected between the lifting plate 12 and the limiting plate 11, and a plurality of limiting holes 111 are arranged at intervals on the limiting plate 11. When placing the crucible, the crucible is placed on the lifting plate 12 after passing through the limiting holes 111, wherein the limiting holes 111 are rectangular. In this way, after the crucible and the crucible stand 1 are placed in the calcining furnace, the inner wall of the limiting hole 111 will not completely contact the outer periphery of the crucible, thereby reducing the risk of the crucible being locally overheated and eventually bursting, improving the operating safety of the staff, and ensuring the stable progress of the high-temperature burning experiment.
[0033] The placing box 2 includes a box body 21, a desiccant and a temperature detection member 22. A partition 23 is provided inside the box body 21. The partition 23 divides the box body 21 into an upper space 211 and a lower space 212. The crucible and the crucible stand 1 after burning are placed in the upper space 211, and the desiccant is placed in the lower space 212. The partition 23 is used to isolate the crucible and the crucible stand 1 with high temperature after burning from the desiccant, which can prevent the desiccant from burning due to high temperature and affecting the use of the desiccant. In this embodiment, by placing a desiccant in the box body 21, the desiccant can absorb moisture in the environment of the box body 21, and prevent the moisture in the environment of the box body 21 from entering the ore when the crucible and the crucible stand 1 are placed in the box body 21 for cooling, thereby ensuring the accuracy of the weighing result. The temperature detection member 22 is arranged in close contact with the outer wall 21 of the box body, which can avoid placing it in a high temperature environment to extend its service life. The detection probe of the temperature detection part 22 faces the box body 21. On the one hand, it can detect the temperature of the box body 21 in real time to assist the staff to know the temperature of the ore so that the weight of the ore can be detected when the ore is at a suitable temperature. On the other hand, the setting of the temperature detection part 22 can ensure that each batch of ore after burning is weighed at the same temperature, ensure the consistency of the detection conditions of different batches of ore, and improve the accuracy of the detection data. The desiccant is preferably color-changing silica gel, which can not only quickly absorb the moisture in the box body 21, but also has a certain high temperature resistance, thereby improving the safety factor of the working environment of the staff. The temperature detection part 22 can be selected to be attached to the bottom surface of the box body 21, or it can be selected to be attached to the side of the box body 21, without specific restrictions. The suitable temperature range is between 20°C and 50°C, and the specific value is determined according to the experimental requirements.
[0034] Preferably, in order to facilitate the production of the limiting plate 11, the limiting hole 111 is in the shape of a square. In order to improve the versatility of the crucible stand 1 and to accommodate crucibles of different heights, in this embodiment, the distance between the limiting plate 11 and the lifting plate 12 can be adjusted. For example, the connecting rod 13 can be designed as a telescopic rod that can be extended to adjust the distance between the lifting plate 12 and the limiting plate 11. Alternatively, an external thread can be provided on the connecting rod 13, a first mounting hole can be provided on the limiting plate 11, a second mounting hole can be provided on the lifting plate 12, and internal threads can be provided on both the first mounting hole and the second mounting hole, so that the limiting plate 11 and the lifting plate 12 are threadedly connected to the connecting rod 13, so that the staff can adjust the distance between the limiting plate 11 and the lifting plate 12 by rotating the limiting plate 11 and the lifting plate 12 in the forward or reverse direction.
[0035] As preferably, Figure 2 As shown in , in order to improve the overall stability of the crucible stand 1, a plurality of connecting rods 13 are provided, and the plurality of connecting rods 13 are arranged at intervals between the limiting plate 11 and the lifting plate 12. In order to enable different crucible stands 1 to be stacked layer by layer, the crucible stand 1 further includes a plurality of supporting legs 14, and the plurality of supporting legs 14 are arranged on the bottom surface of the lifting plate 12. The arrangement of the supporting legs 14 enables the lifting plate 12 of the upper crucible stand 1 to be spaced from the limiting plate 11 of the lower crucible stand 1, so as to ensure that the crucibles of the upper and lower crucible stands 1 can be stably placed.
[0036] In this embodiment, the placement box 2 also includes a humidity detection member, which is placed in the box body 21 and is used to detect the humidity in the box body 21, so that the staff can replace the desiccant to ensure the dry environment in the box body 21 in real time and ensure the accuracy of the weighing data. At the same time, in order to ensure the service life of the humidity detection member, the staff will take out the humidity detection member before putting the calcined crucible and the crucible rack 1 into the placement box 2 to avoid damage to the humidity detection member in a high temperature environment.
[0037] Preferably, the placement box 2 also includes a first alarm component and a second alarm component, wherein the first alarm component is located on the bottom surface of the box body 21 and is electrically connected to the temperature detection component 22. When the temperature detection component 22 reaches a predetermined temperature, an electrical signal is transmitted to the first alarm component, at which time the first alarm component emits an alarm prompt sound, informing the staff to take the crucible and the crucible rack 1 out of the placement box 2. The second alarm component is electrically connected to the humidity detection component. When the humidity in the box body 21 is too high, the humidity detection component transmits an electrical signal to the second alarm component, at which time the second alarm component emits an alarm prompt sound, informing the staff to replace the desiccant. At the same time, to facilitate the staff to distinguish, in this embodiment, the alarm prompt sounds emitted by the first alarm component and the second alarm component belong to different audio frequencies.
[0038] In order to ensure the service life of the placement box 2 and ensure that the crucible and the crucible stand 1 are cooled quickly, in this embodiment, the box body 21 and the partition 23 are both made of aluminum alloy. At the same time, the placement box 2 is also provided with a handle 24, which is arranged on the top of the box body 21, so that the staff can take the placement box 2.
[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
