Description

Technical Field

[0001] This application relates to the field of mineral detection technology, and in particular to an auxiliary tool for a sulfur analyzer used in mineral detection. Background Technology

[0002] The sulfur content in ore depends on the type and composition of the ore, as well as its formation environment. Generally, the higher the sulfur content, the lower the quality of the ore. Excessively high sulfur content not only affects the quality of the ore but also negatively impacts its processing performance. Taking coal mines as an example, the sulfur content in coal has a significant environmental impact; the combustion of high-sulfur coal produces large amounts of sulfur dioxide, leading to environmental problems such as acid rain. Therefore, detecting the sulfur content in coal samples during production and use is a crucial task. Currently, the commonly used tool for sulfur determination is a sulfur analyzer (also known as a sulfur meter), which primarily utilizes the coulometric titration principle to determine the sulfur content in coal.

[0003] The general procedure for determining the sulfur content in mineral samples such as coal using a sulfur analyzer is as follows:

[0004] 1. Turn on the power switch of the equipment to allow the instrument to automatically heat up the furnace. 2. Turn on the gas pump switch of the sulfur analyzer, check for leaks, and adjust the gas flow rate to approximately 1000 mL / min. Turn on the stirrer switch and check if the speed is appropriate. 3. When the furnace temperature reaches 1050℃, turn on the electrolysis switch, press the electrolysis button, and observe if the electrolysis voltage is normal. 4. Weigh approximately 50 mg of coal sample onto the ceramic boat, place the boat on the quartz tray in the sample delivery area of ​​the equipment, press the start button, enter the sample weight, and press the start button again to begin the test. After the test begins, the temperature will be paused at 500℃ and 1150℃ respectively. The dwell time is determined according to the set input time and the time until the coal sample is completely burned. After the sample is burned, coulometric titration will proceed automatically. The entire test process will be executed by the program. Once the quartz tray and ceramic boat return to their original positions, the printer will print the results, and the test will be completed. After the sulfur analyzer test is completed, turn off the electrolysis switch, release the electrolyte, rinse the electrolysis cell with distilled water, and then turn off the purification device.

[0005] When weighing items on a porcelain boat, a spatula is usually used to add the sample to a certain area of ​​the boat. This makes the sample relatively concentrated on the boat. In order to ensure that the sample burns completely in the furnace, the tester needs to place the boat on his palm or a table and shake it horizontally to spread the sample evenly inside. However, the height of the porcelain boat is usually quite shallow, generally about 0.8cm to 1.2cm, and its top is an open structure. During the shaking process, the sample inside the boat may be spilled out if not handled carefully, which will change the weight of the sample inside the boat and affect the accuracy of the final sulfur content test. Utility Model Content

[0006] This application provides an auxiliary tool for a sulfur analyzer used in mineral testing, which can reduce the risk of materials spilling out of the porcelain boat during the shaking process.

[0007] The above-mentioned objective of this application is achieved through the following technical solution:

[0008] An auxiliary tool for a mineral sulfur analyzer includes a porcelain boat with an open top. One end of the porcelain boat has a traction hole. A cover plate is placed on top of the porcelain boat, and the shape of the cover plate is the same as the shape of the edge contour of the upper port of the porcelain boat. The area of ​​the cover plate is such that when it is placed on the upper port of the porcelain boat, it can completely close the upper port of the porcelain boat.

[0009] A feeding module is provided at the middle position of the upper side of the cover plate. The lower end of the feeding module is fixedly connected to the upper side of the cover plate. An external feeding through hole is provided at the center of the feeding module along the vertical direction. An internal feeding through hole is provided at the position corresponding to the external feeding through hole on the cover plate.

[0010] The cover plate has an integrally formed downward-extending folded edge on each of its two sides in the width direction, and the distance between the two folded edges at the same height and the side closest to each other is equal to the width of the porcelain boat at the corresponding position.

[0011] Furthermore, the cross-section of the porcelain boat is an isosceles trapezoid.

[0012] Furthermore, a wrap-around snap-fit ​​part is fixedly provided on the lower side of one end of the cover plate. The two ends of the wrap-around snap-fit ​​part along the width direction of the cover plate are respectively fixedly connected to the two ends of the downward-curving edge on the same side. The wrap-around snap-fit ​​part is provided with an embedded groove on the side facing the center of the cover plate. The shape of the embedded groove matches the external shape of the end of the ceramic boat that is provided with the traction hole.

[0013] Furthermore, a pin is movably inserted into the cover plate at a position corresponding to the traction hole on the porcelain boat. The lower end of the pin passes through the traction hole on the porcelain boat and continues to extend downward until it penetrates the wrap-around snap-fit ​​part.

[0014] Furthermore, the external feeding through hole is shaped like a pyramidal shape, the width of the upper port of the external feeding through hole is greater than the width of the upper port of the ceramic boat, and the width of the lower port of the external feeding through hole and the width of the internal feeding through hole are both equal to the width of the upper port of the ceramic boat.

[0015] Furthermore, the feeding module has a recessed clamping area on each side along the width direction of the cover plate.

[0016] Furthermore, the upper ends of the two clamping areas that are close to each other are inclined toward the center of the external feeding through hole.

[0017] Furthermore, multiple anti-slip crossbeams are evenly arranged along the length of the clamping area.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] Because this application adds a cover plate to the porcelain boat, it effectively prevents the material in the porcelain boat from spilling out during the shaking process. This also avoids loss of sample weight due to spillage, ensuring the accuracy of the sulfur analyzer's final sulfur content detection. A feeding module is also added to the middle of the cover plate. The tester can easily feed the sample into the middle of the porcelain boat through the external feeding through-hole on the feeding module and the internal feeding through-hole on the cover plate. This helps to quickly and evenly distribute the sample within the porcelain boat when it is shaken. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0029] like Figures 1-3 As shown, this application discloses an auxiliary tool for a mineral detection sulfur analyzer, including a porcelain boat 1 with an open top, a traction hole 2 at one end of the porcelain boat 1, and a cover plate 3 covering the top of the porcelain boat 1. The shape of the cover plate 3 is the same as the shape of the edge of the upper port of the porcelain boat 1. The area of ​​the cover plate 3 is such that when it is placed on the upper port of the porcelain boat 1, it can completely close the upper port of the porcelain boat 1.

[0030] A feeding module 4 is provided in the middle of the upper side of the cover plate 3. The lower end of the feeding module 4 is fixedly connected to the upper side of the cover plate 3. An external feeding through hole 5 is provided in the center of the feeding module 4 along the vertical direction. An internal feeding through hole 6 is provided on the cover plate 3 at the position corresponding to the external feeding through hole 5.

[0031] The cover plate 3 has an integrally formed downward-extending folded edge 7 on both sides in the width direction, and the distance between the two folded edges 7 at the same height and the side closest to each other is equal to the width of the porcelain boat 1 at the corresponding position.

[0032] In the above embodiments, the porcelain boat 1, also called a combustion boat or combustion vessel, is a container used for firing materials or products produced and used in various industries. It is suitable for analyzing the carbon and sulfur content in mineral samples and for analyzing volatile components in lightweight samples. A common porcelain boat 1 is boat-shaped, with a traction hole 2 at one end, a flat bottom for stable placement, and an open top for easy sample addition and to allow relevant components in the sample to volatilize during heating in the furnace, as well as for oxygen and other relevant gases from the air to enter the porcelain boat 1 and react with the sample. Common porcelain boat 1 dimensions are typically 7.2cm–9.7cm in length, 1.2cm–1.7cm in width, and 0.8cm–1.2cm in height. When adding the sample to the ceramic boat 1, the tester needs to use tweezers 13 to place the ceramic boat 1 onto a high-precision balance, and then use a spatula to add the sample onto the ceramic boat 1. Due to the limited space inside the high-precision balance and the small amount of sample required to be added to the ceramic boat 1, the tester usually completes the task in two to three additions. Therefore, the sample distribution inside the ceramic boat 1 is relatively concentrated. In order to ensure that the sample on the ceramic boat 1 can burn completely in the furnace, the tester needs to place the ceramic boat 1 on the palm of their hand or on a table and shake it back and forth before placing it into the sulfur analyzer to ensure that the sample is evenly distributed inside the ceramic boat 1. Because the ceramic boat 1 is relatively low, the sample can easily spill out during the shaking process. If this is not noticed in time and remedial measures are not taken, the accuracy of the final measured sulfur content will be affected by the change in the overall weight of the sample inside the ceramic boat 1.

[0033] This application adds a cover plate 3 to the porcelain boat 1. The shape of the cover plate 3 is identical to the shape of the open top of the porcelain boat 1, and its dimensions are equal to the outer contour of the upper port of the porcelain boat 1. Thus, when the cover plate 3 is fastened to the porcelain boat 1, it temporarily seals the upper port of the porcelain boat 1. This effectively prevents the sample from spilling out of the upper opening when the porcelain boat 1 needs to be shaken, ensuring the accuracy of the final sulfur content detection. To reduce sample adhesion to the cover plate 3 during shaking, if the cover plate 3 is made of metal, its surface can be polished; if it is made of ceramic, its surface can be glazed. The downward-curving edges 7 on both sides of the cover plate 3 along the width direction, as described above, allow the tester to quickly and accurately fasten the cover plate 3 to the upper port of the porcelain boat 1. Furthermore, the downward-curving edges 7 can cover the gap between the two long sides of the porcelain boat 1 and the cover plate 3, further reducing the risk of sample spillage during shaking. When the porcelain boat 1 is shaken, if the initial position of the sample is in the middle of the porcelain boat 1, it will help to quickly and evenly shake the sample during the shaking process. In this application, the feeding module 4 set at the center of the cover plate 3 allows the tester to smoothly feed the sample into the middle position inside the porcelain boat 1 through the external feeding through hole 5 on the feeding module 4 and the internal feeding through hole 6 on the cover plate 3. This helps to quickly and evenly shake the sample inside the porcelain boat 1 when shaking the porcelain boat 1.

[0034] Furthermore, such as Figure 3 As shown, the cross-section of the porcelain boat 1 is an isosceles trapezoid.

[0035] In the above embodiments, the cross-section of the porcelain boat 1 of this application is an isosceles trapezoid, with the width of its long end being greater than the width of its bottom. Referring to the previous embodiment, it can be seen that the distance between the two adjacent sides of the two downward-curving edges 7 located at the same height below the cover plate 3 is equal to the width of the porcelain boat 1 at the corresponding position, and the downward-curving edges 7 and the corresponding porcelain boat 1 have a certain degree of overlap. When the cross-section of the porcelain boat 1 of this application is an isosceles trapezoid, the adjacent sides of the two downward-curving edges 7 of this application are inclined walls with the same inclination as the two side walls in the width direction of the porcelain boat 1. Thus, when the tester fastens the cover plate 3 onto the porcelain boat 1, the lower part of the cover plate 3 is first... Align the surface with the top of the porcelain boat 1, then insert the upper half of the porcelain boat 1 between the two downward-curving edges 7, and push the cover plate 3 along the length of the porcelain boat 1 until it completely covers the porcelain boat 1, thus completing the combination of the two. Since the cross-section of the porcelain boat 1 is wider at the top and narrower at the bottom, the cross-section of the space enclosed by the two downward-curving edges 7 and the cover plate 3 is also a matching shape that is wider at the top and narrower at the bottom. In this way, the lower end of the downward-curving edge 7 can limit the porcelain boat 1 in the vertical direction during the use of the porcelain boat 1. When the tester takes the entire tool out of the balance, even if the tester uses tweezers 13 to hold the cover plate 3, the porcelain boat 1 can still be taken out smoothly together.

[0036] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, a wrap-around snap-fit ​​part 8 is fixedly provided on the lower side of one end of the cover plate 3. The two ends of the wrap-around snap-fit ​​part 8 along the width direction of the cover plate 3 are respectively fixedly connected to the ends of two downward-curving edges 7 on the same side. The wrap-around snap-fit ​​part 8 is provided with an embedded groove 9 on the side facing the center of the cover plate 3. The shape of the embedded groove 9 matches the external shape of the end of the porcelain boat 1 where the traction hole 2 is located.

[0037] In the above embodiments, the wrap-around snap-fit ​​part 8, which is set under one end of the cover plate 3 in accordance with the above method, can limit the end of the porcelain boat 1 with the traction hole 2 by using the embedded groove 9 on the wrap-around snap-fit ​​part 8 when the test personnel push the cover plate 3 to move at the upper end of the porcelain boat 1. This allows the test personnel to quickly and accurately perceive that the cover plate 3 has been snapped into place on the porcelain boat 1, thereby effectively improving the speed at which the test personnel can assemble the cover plate 3 and the porcelain boat 1 together.

[0038] Furthermore, such as Figures 1-4 As shown, a pin 10 is movably inserted on the cover plate 3 at a position corresponding to the traction hole 2 on the porcelain boat 1. The lower end of the pin 10 passes through the traction hole 2 on the porcelain boat 1 and continues to extend downward until it penetrates the wrap-around snap-fit ​​part 8.

[0039] In the above embodiments, this application provides a through hole on the cover plate 3 and the wrap-around snap-fit ​​part 8 below it, at the position corresponding to the traction hole 2 on the porcelain boat 1. When the cover plate 3 is fastened to the porcelain boat 1, the two through holes and the traction hole 2 on the porcelain boat 1 also form a through hole. At this time, the pin 10 is inserted into the hole, which can further restrict the movement of the cover plate 3 along the length direction of the porcelain boat 1. In this way, whether it is moving the whole tool or shaking the whole tool, the stability of the connection between the cover plate 3 and the porcelain boat 1 can be further improved, and the risk of the sample spilling out of the porcelain boat 1 can be reduced.

[0040] Furthermore, such as Figures 1-3 As shown, the external feeding through hole 5 is shaped like a pyramidal shape. The width of the upper port of the external feeding through hole 5 is greater than the width of the upper port of the ceramic boat 1. The width of the lower port of the external feeding through hole 5 and the width of the internal feeding through hole 6 are both equal to the width of the upper port of the ceramic boat 1.

[0041] In the above embodiments, since the porcelain boat 1 itself is relatively narrow, it is easy for the test personnel to spill the sample onto the balance when adding the sample to the porcelain boat 1. The external feeding through hole 5 of this application is set in the above manner, so that it can form a channel with the upper port being larger than the lower port. The width of the lower port of the external feeding through hole 5 is equal to the width of the internal feeding through hole 6, and the width of the internal feeding through hole 6 is equal to the width of the upper port of the porcelain boat 1. The width of the upper port of the external feeding through hole 5 is larger than the width of its lower port. In this way, when the test personnel add the sample to the porcelain boat 1 through the external feeding through hole 5, the risk of the sample spilling onto the balance can be effectively reduced.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the feeding module 4 has a recessed clamping area 11 on each side along the width direction of the cover plate 3.

[0043] In the above embodiments, the recessed clamping area 11 provided on the feeding module 4 in this application makes it convenient for the test personnel to quickly align the feeding module 4 with the middle position using tweezers 13. In this way, when the test personnel use tweezers 13 to clamp the entire tool, the entire tool can be subjected to more balanced force.

[0044] Furthermore, such as Figure 5 and Figure 6 As shown, the upper ends of the two clamping areas 11 that are close to each other are inclined towards the center of the feed hole 5.

[0045] In the above embodiments, the common tweezers 13 are V-shaped. In this application, both clamping areas 11 on the feeding module 4 are set in the above manner. When the test personnel clamp the feeding module 4 with the opening of the tweezers 13, the contact area between the tweezers 13 and the clamping area 11 is effectively increased, thereby improving the stability of the clamping process.

[0046] Furthermore, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, multiple anti-slip beams 12 are evenly arranged along the length of the clamping area 11.

[0047] In the above embodiments, the anti-slip crossbeam 12 on the clamping area 11 and the anti-slip teeth at the opening of the tweezers 13 can cooperate with each other, greatly increasing the resistance between the tweezers 13 when they clamp the entire tool and move it. The resistance from the clamping area 11 to the tweezers 13 helps the tweezers 13 to clamp it more firmly and stably. The resistance from the clamping area 11 to the entire tool helps the tweezers 13 to smoothly clamp the entire tool and move it smoothly in the air.

[0048] The implementation principle of this embodiment is as follows: When the tester needs to measure the sulfur content of a mineral sample, the equipment can be turned on and preheated first. Then, the cover plate 3 of this application is fastened onto the ceramic boat 1. The clamping area 11 on the feeding module 4 of the cover plate 3 is held with tweezers 13. The ceramic boat 1 and the cover plate 3 are placed together in the balance. The tare button of the balance is pressed. The sample to be tested is slowly added into the ceramic boat 1 through the external feeding through hole 5 on the feeding module 4 using a spatula. The ceramic boat 1 is observed in real time during this process. After the weight of the sample inside is appropriate, use tweezers 13 to hold the clamping area 11 on the feeding module 4 and remove the cover plate 3 and the porcelain boat 1 from the balance together. In order to spread the sample inside the porcelain boat 1 evenly, the tester can hold the porcelain boat 1 and shake it on the table. After the sample inside the porcelain boat 1 is shaken evenly, the entire tool can be moved to the sample feeding area of ​​the sulfur analyzer using tweezers 13. After removing the cover plate 3, the start button on the control panel of the sulfur analyzer can be pressed to officially start the sulfur measurement test.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
