Description

Technical Field

[0001] The present invention relates to the technical field of boron content determination, and in particular to a device and method for testing the boron content in boron-containing carbon materials. Background Art

[0002] Generally, the boron content in boron-containing carbon materials comes primarily from the addition of boron carbide. Boron carbide, also known as black diamond, is an inorganic substance with the chemical formula B₄C. It typically appears as a gray-black powder and is one of the three hardest known materials. Existing boron-containing carbon materials can be used in tank armor, bulletproof vests, and many other industrial applications. However, limited testing methods are available for these materials, making it difficult to determine their quality.

[0003] Currently, the most common method for determining boron in other materials is the titration test method, which involves placing the sample in a crucible and then heating it in a high-temperature furnace to form a melt. The sample is then placed in a quartz beaker filled with water, heated for leaching, and ethanol is added. The mixture is boiled for 3-5 minutes. The crucible is then removed, cleaned, cooled, transferred to a volumetric flask, diluted to the mark with water, mixed, and allowed to stand for a while before subsequent determination. Existing sample structures are mostly irregular in shape and weighed by weight, requiring melting and then dissolving. This results in low dissolution efficiency and a complex process. Furthermore, melting in a crucible is required, and because the melt adheres to the crucible and is difficult to separate, this separation method cannot achieve complete separation of the melt, resulting in low efficiency and affecting the accuracy of subsequent content determinations.

[0004] Chinese patent CN 105289777B discloses a crucible support for ash content determination. The crucible support has a crucible placement position provided in the frame body of the crucible support, and a support leg is provided at the bottom of the frame body. At least two clamping parts are provided in the crucible placement position, and the clamping parts include an upper clamping piece and a lower clamping piece connected by a hinge. The lower clamping piece is also hinged to the inner wall of the crucible placement position. The upper clamping piece is provided with a strip hole. The inner wall of the crucible placement position is provided with a limit rod, and the limit rod is inserted into the strip hole; the frame body is also equipped with a split extraction handle, and the end of the extraction handle is provided with a crucible base. There is a protrusion above the crucible base, and the protrusion protrudes from the top of the extraction handle.

[0005] However, although this technical solution can accurately remove and place the crucible on the crucible stand, it is not convenient to cool the crucible while the crucible is heating the raw material. Moreover, after cooling, due to the mutual adhesion between the melt and the crucible body, it is difficult to quickly remove the condensed melt from the crucible, which affects the accuracy of the content determination. Summary of the Invention

[0006] The object of the present invention is to address the deficiencies of the prior art and provide an apparatus and method for testing the boron content in boron-containing carbon materials. The apparatus and method comprise the following steps: sending a container component loaded with the boron-containing carbon material, anhydrous sodium carbonate and potassium nitrate into a smelting component to complete smelting; then, tilting and rotating the container component so that the melt adheres to the wall of the container component in an annular sheet state and is cooled by self-rotation; after the melt is cooled into an annular sheet, the melt is rotated and separated from the inner wall of the container component by a discharge component, and then pushed out from the bottom of the container component and discharged into a beaker filled with hydrochloric acid solution; and the beaker is continuously shaken so that the frit is quickly dissolved, thereby improving the efficiency and accuracy of subsequent boron content testing, thereby solving the technical problems described in the background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0009] Furthermore, the turning assembly includes: a transfer assembly; and a cooling assembly, and the cooling assembly that drives the charging assembly to be arranged obliquely and rotated for cooling is installed on the power end of the transfer assembly.

[0010] Furthermore, the cooling assembly includes: a locking assembly for loading and unloading the charging assembly in the smelting assembly; and a rotating assembly for obliquely arranging the locking assembly that clamps the charging assembly and rotating the charging assembly.

[0011] Furthermore, the cooling assembly also includes: a driving assembly that drives the locking assembly that clamps the loading assembly to be transferred to the lower cover assembly and the blanking assembly in sequence.

[0012] Furthermore, the accommodating component includes: several groups of split parts arranged in sequence along the axial direction to form an accommodating chamber; a transmission component that drives several groups of the split parts to open / close the accommodating chamber, and the transmission component is connected to the blanking component in a transmission manner; and a fastener that is used to lock the upper cover assembly and drive the fastener of the cover body to be installed on the split part.

[0013] Furthermore, the transmission assembly includes: a bracket for movably mounting the split part; a transmission tooth, the transmission tooth being mounted on the top of the split part; a transmission rack, the transmission rack being transmission-connected to the transmission tooth; and a feed assembly, the feed assembly being mounted on the bracket for linking with the blanking assembly to provide feeding power to the transmission rack.

[0014] Furthermore, the feed assembly includes: a feed screw that moves through the bracket and threads through the transmission rack; a guide member, the guide member installed on the bracket slides through the transmission rack; and a linkage member, the linkage member for rotating the feed screw is installed on the feed screw.

[0015] Furthermore, the cover includes: a main body, with a plurality of exhaust spaces uniformly distributed on the circumference of the main body; a sealing member for sealing the exhaust space, the sealing member being arranged corresponding to the fastener and slidably mounted on the main body.

[0016] Furthermore, the blanking component includes: a rotating disk that cooperates with the linkage component in transmission; a power pusher, which is installed in the middle of the bottom of the rotating disk and pushes the annular sheet-shaped melt in the accommodating component downward; a lifting power component for driving the rotating disk to move up and down; and a rotating power component for driving the rotating disk and the power pusher to rotate.

[0017] The present invention also provides a method for detecting the total boron content using an apparatus for testing the boron content in a boron-containing carbon material, characterized in that it comprises the following steps:

[0018] Step 1: Loading and exhausting: weigh the boron-carbon ash material into the containing component, then add anhydrous calcium carbonate and potassium nitrate, stir evenly, and place it on the cooling component. Install the cover assembly onto the containing component and open the exhaust space for exhausting;

The lifting power component driven by the rotating power component drives the rotating disk to move downward to contact the linkage component, so that the feed screw drives the transmission rack to transmit the transmission to the transmission tooth, so that the split component opens to discharge the annular flaky melt. At the same time, the power pusher pushes the annular flaky melt downward to separate it from the split component.

[0022] The beneficial effects of the present invention are:

[0023] (1) The present invention can realize the automatic locking and removal of the cover body on the accommodating assembly before and after the raw materials are smelted by the mutual cooperation between the upper cover assembly, the lower cover assembly and the charging assembly. At the same time, it can also realize the opening and closing of the exhaust space of the cover body, thereby realizing the exhaust treatment during the raw materials reaction and ensuring the melting quality;

[0024] (2) The present invention can remove the smelting container assembly after smelting by cooperating with the rotating assembly, and keep the loading assembly in an oblique rotation state for cooling, so that the molten material is cooled into an annular sheet structure with a large surface area, thereby solving the contact area when dissolving in the hydrochloric acid solution, thereby improving the dissolution efficiency and sufficiency of the molten material, and facilitating the improvement of the accuracy and efficiency of the subsequent boron content test;

[0025] (3) The present invention, through the cooperation between the accommodating component and the blanking component, can gradually open the channel of the accommodating component for discharging the molten material downward while pushing the molten material cooled into an annular sheet in the accommodating component downward through the blanking component. At the same time, the molten material is rotated to both sides to separate from the inner wall of the accommodating component, thereby solving the problem that when the downward pushing force is large, the molten material is ejected from the ejection channel of the accommodating chamber and damaged the container for dissolving the molten material;

[0026] (4) The present invention uses a split-type accommodating component to realize that after the molten material solidifies, the bottom channel for discharge can be rotated around the connection point with the bracket as the center, thereby better realizing the discharge action of the molten material after solidification, solving the technical problem that the molten material is difficult to remove when taking the material from the top, which affects the accuracy of the boron element test content;

[0027] (5) The present invention, through the coordinated design between the power pusher and the split part, can realize that while the power pusher pushes the molten material downward, the split part is linked to gradually open the bottom channel, and while pushing the molten material, the molten material is in a rotating state relative to the inner wall of the split part, so that the molten material can be separated from the inner wall of the split part along the rotation direction, thereby ensuring the safety of the separation between the molten material and the split part;

[0028] In summary, the present invention is particularly suitable for the detection of total boron content. It has the advantages of melting and cooling the mixed boron-containing carbon material, anhydrous sodium carbonate and potassium nitrate into annular sheets with a large dissolution area, and forming or quickly separating the formed melt from the accommodating chamber. It greatly improves the test accuracy and test efficiency of the boron element content, reduces the auxiliary equipment for determination, and simplifies the determination process.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0045] Example 1

[0046] like Figure 1 and 2As shown, a device for testing the boron content in boron-containing carbon materials includes a frame 1, and also includes: a charging component 2 for loading boron-containing carbon materials, anhydrous sodium carbonate and potassium nitrate, the charging component 2 including: a receiving component 21 and a cover 22 provided on the top of the receiving component 21; a turning component 3 for moving the charging component 2 and making the charging component 2 rotate obliquely and sliding on the frame 1; a smelting component 4 for melting the raw materials in the charging component 2 placed by the turning component 3; the smelting component 4 is provided below the frame 1; an upper cover component 5 for locking the cover 22 on the receiving component 21 and driving the cover 22 to open and close the discharge port. The upper cover assembly 5 is arranged on one side of the smelting assembly 4; the lower cover assembly 6, which is used to remove the cover body 22 from the accommodating assembly 21, is arranged on the other side of the smelting assembly 4; and the blanking assembly 7, which drives the accommodating assembly 21 with the cover body 22 removed to open and rotate to push out the molten block, is arranged on one side of the lower cover assembly 6; the turning assembly 3 removes the charging assembly 2 from the smelting assembly 4, and puts the charging assembly 2 in an oblique rotation state, so that the molten material rotates and cools into an annular sheet shape, and the blanking assembly 7 drives the accommodating assembly 21 with the cover body 22 removed through the lower cover assembly 6 to open, and at the same time, the annular sheet molten material is rotated and pushed out from the bottom of the opened accommodating assembly 21.

[0047] It is not difficult to find from the above content that in the process of detecting the total boron content of the boron-containing carbon material, the boron-containing carbon material, anhydrous sodium carbonate and potassium nitrate are quantitatively added to the charging component 2, and the charging component 2 is placed under the upper cover component 5, and the cover 22 is covered on the accommodating component 21 by turning the component 3, and the cover 22 is controlled to be in an open state to discharge the reaction gas of the boron-containing carbon material, anhydrous sodium carbonate and potassium nitrate, and then the upper cover component 5 closes the cover 22 and locks the cover 22 on the accommodating component 21, and turns The rotating assembly 3 transfers the charging assembly 2 to the smelting assembly 4 for heating and melting. After the smelting is completed, the rotating assembly 3 takes out the charging assembly 2 and makes the charging assembly 2 in an inclined state, and continuously drives the charging assembly 2 to rotate in the inclined state, thereby realizing the continuous cooling of the melt by the self-rotation action. At the same time, the melt can be gradually cooled and solidified into an annular sheet in contact with the bottom edge of the accommodating assembly 21. By processing the melt into an annular sheet state when solidifying, the melt is increased. The surface area of ​​the block after forming can realize the contact area when the molten material is dissolved in the hydrochloric acid solution, thereby improving the dissolution efficiency of the molten material in the hydrochloric acid solution; then, after the turning component 3 cools and forms the molten material, the turning component 3 carries the loading component 2 to the side of the blanking component 6, and the cover body 22 is removed by controlling the lower cover component 6. The turning component 3 continues to carry the loading component 2 to the action area of ​​the blanking component 7, and the blanking component 7 drives the accommodating component 21 to open, and at the same time rotates downward to push the annular sheet molten material, so that the molten material is discharged from the opened container. The molten material is discharged from the bottom of the receiving component 21. During the process of the blanking component 7 discharging the molten block, the receiving component 21 is gradually opened, and the blanking component 7 pushes and rotates the molten material in the inner cavity of the receiving component 21, so that the molten material can be quickly separated from the inner wall of the receiving component 21, thereby ensuring the discharge efficiency of the molten material and solving the problem that when the molten material is forcibly pushed downward and the adhesion between the molten material and the inner wall of the receiving component 21 is large, the molten material will be ejected during separation, thereby damaging the dissolved gas, such as the beaker container filled with hydrochloric acid solution used to dissolve the molten block.

[0048] like Figure 2 As shown, the transfer assembly 3 includes: a transfer assembly 31; and a cooling assembly 32. The cooling assembly 32 that drives the charging assembly 2 to be arranged obliquely and rotated for cooling is installed on the power end of the transfer assembly 31.

[0049] In this embodiment, during the process of rotating the charging component 2, the turning component 3 can realize the sequential transfer processing of the upper cover component 5, the melting component 4, and the lower cover component 6 of the charging component 2 by utilizing the transfer component 31, and by utilizing the cooling component 32, not only the clamping transfer of the accommodating component 21 can be realized, but also the accommodating component 21 after the melting treatment can be tilted and driven to rotate, thereby realizing the cooling treatment of the melt while also being able to cool the melt into annular sheets during the rotation process, thereby effectively increasing the surface area of ​​the melt after cooling, ensuring the contact area in the hydrochloric acid solution, and thus improving the dissolution efficiency of the frit in the hydrochloric acid solution.

[0050] It is worth noting that the transfer assembly 31 includes a transfer screw 311 installed on the frame 1, a transfer block 312 threadedly installed on the transfer screw 311 and symmetrically arranged, a slide rod 313 connected to the transfer block 312, a slider 314 sliding on the slide rod 313, and a transfer power part 315 installed on another group of the transfer blocks 312 and pushing the slider 314 to move back and forth on the slide rod 313.

[0051] In this embodiment, the transfer power part 315 is preferably a push rod motor. Through the power of the transfer power part 315, the cooling component 32 can be driven to move along the horizontal direction. By utilizing the power of the servo motor to drive the transfer screw 311 to rotate, the cooling component 32 connected to the transfer block 312 can be driven to move along the longitudinal direction, so that when the cooling component 32 carries the accommodating component 21 to the side of the smelting component 4, the accommodating component 21 can be pushed into the molten material component 4.

[0052] like Figure 8 and 9 As shown, the cooling assembly 32 includes: a locking assembly 321 for loading and unloading the charging assembly 2 in the smelting assembly 4; and a rotating assembly 322 for slanting the locking assembly 321 that clamps the charging assembly 2 and allowing the charging assembly 2 to rotate.

[0053] In this embodiment, while the cooling assembly 32 is used to control the tilting arrangement and rotation of the charging assembly 2, the locking assembly 321 is driven by the transfer assembly 31 to re-enter the smelting assembly 4 that has completed melting to lock the charging assembly 2. After locking, the transfer assembly 31 is used to push the charging assembly 2 out of the smelting assembly 4, and the rotating assembly 322 is used to control the tilting arrangement of the locked charging assembly 2 while driving the charging assembly 2 to rotate continuously until the melt is cooled and solidified into a ring-shaped sheet.

[0054] It should be added that, Figure 9As shown, the locking assembly 321 includes a locking seat 321, locking blocks 3212 provided at both ends of the locking seat 321 and symmetrically arranged at both ends of the locking seat 321, a locking screw 3213 installed on the locking seat 321 and threaded through the locking block 3212, and a locking motor 3214 arranged on the locking seat 321 and with the power end connected to the locking screw 3213. The connecting threads of the symmetrically arranged locking blocks 3212 and the locking screw 3213 are reverse threads to each other.

[0055] In this embodiment, the locking motor 3214 is preferably a servo motor, which drives the locking screw 3213 to rotate by rotating the locking motor 3214, thereby driving the two symmetrical sets of locking blocks 3212 to move in opposite directions, thereby completing the clamping action in the clamping area of ​​the loading assembly 2.

[0056] It is also necessary to add that Figure 8 and 9 As shown, the rotating assembly 322 includes a base 3221, a tilting seat 3222 movably mounted on the base 3221, a rotation motor 3223 mounted on the tilting seat 3222, a tilting power motor 3224 movably mounted on the base 3221 and having its power end movably connected to one end of the tilting seat 3222, and a driving seat 3225 provided at the bottom of the tilting seat 3222 and connected to the power end of the rotation motor 3223.

[0057] In this embodiment, the tilting seat 3222 is driven to rotate and tilt around the connection point with the base 3221 by the tilting power motor 3224, which is preferably a push rod motor, so that the accommodating component 21 is arranged in a tilted state. Then, in this tilted state, the rotating seat 3225 is driven to rotate by the rotating motor 3223, which is preferably a servo motor, so that the tilted accommodating component 21 cools the molten material into a ring-shaped sheet state in the tilted state.

[0058] like Figure 8 As shown, the cooling assembly 32 further includes: a driving assembly 323 that drives the locking assembly 321 for clamping the loading assembly 2 to be transferred to the lower cover assembly 6 and the blanking assembly 7 in sequence.

[0059] In this embodiment, by utilizing the power of the driving assembly 323, the locking assembly 321 can be driven to rotate, so that the accommodating assembly 21 can be rotated and conveyed to the lower cover assembly 6 and the blanking assembly 7 in sequence.

[0060] like Figure 8As shown, the driving assembly 323 includes a steering gear 3231 installed on the driving seat 3225, a steering rack 3232 engaged on one side of the steering gear 3231, and a pushing member 3233 installed on the driving seat 3225 and connected to the steering rack 3232 at the power end.

[0061] In this embodiment, the steering rack 3232 is driven to move back and forth by the pushing member 3233 , which is preferably a cylinder, thereby driving the steering gear 3231 to rotate, so as to achieve the purpose of controlling the driving rotation of the charging assembly 2 .

[0062] It should be noted that if Figure 8 As shown, in order to enable the locking assembly 321 to carry the loading assembly 2 to complete the downward lifting action, the bottom of the driving seat 3225 is provided with a lifting motor 324 connected to the steering gear 3232, and the lifting motor 324 is preferably a push rod motor.

[0063] like Figure 11 As shown, the smelting assembly 4 includes a smelting chamber 41, a smelting bracket 44 arranged in the smelting chamber 41 corresponding to the accommodating assembly 21, a chamber door 42 arranged on one side of the smelting chamber 41, and a sliding door power member 43 that drives the chamber door 42 to move toward the side of the smelting chamber 41 for blocking.

[0064] In this embodiment, the door sliding power member 43 is preferably a cylinder. Under the power of the door sliding power member 43, the chamber door 42 seals the smelting chamber 41. Before sealing, the transfer assembly 31 can be driven by moving the chamber door 42 away, so that the accommodating assembly 21 is placed on the smelting support 44.

[0065] Example 2

[0066] like Figure 3-5 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0067] The accommodating component 21 includes: several groups of split parts 211 arranged in sequence along the axial direction to form an accommodating chamber 212; a transmission component 213, which drives several groups of the split parts 211 to open / close the accommodating chamber 212, and the transmission component 213 is connected to the blanking component 7 for transmission; and a fastener 214, which is used to lock the upper cover component 5 and drive the fastener 214 of the cover body 22 to be installed on the split part 211.

[0068] In this embodiment, when the split parts 211 are all brought together to form the accommodating chamber 212, the loading and tilting rotation cooling of the molten material can be achieved, and when it reaches the blanking component 7, the blanking component 7 will transmit the material to the transmission component 213 while pushing the material, thereby driving each split part 211 to rotate, so that the bottom of the split part 211 is opened, and the blanking component 7 pushes the molten material downward while rotating with the molten material in the split part 211, thereby achieving separation from the split part 211 and reducing the downward impact force when the molten material is pushed out.

[0069] Preferably, the split component 211 is made of platinum.

[0070] It is worth noting that when the cover body 22 is placed on the accommodating component 21, the top of the cover body 22 is driven by the upper cover component 5 and the lower cover component 7 to cover the bottom of the fastener 214, thereby locking the cover body 22 on the accommodating component 21.

[0071] like Figure 4 As shown, the transmission assembly 213 includes: a bracket 2131 for movably mounting the split part 211; a transmission tooth 2132, the transmission tooth 2132 being mounted on the top of the split part 211; a transmission rack 2133, the transmission rack 2133 being transmission-connected to the transmission tooth 2132; a feeding assembly 2134, the feeding assembly 2134 being mounted on the bracket 2131 for linking with the blanking assembly 7 to provide feeding power to the transmission rack 2133.

[0072] In this embodiment, when the unloading component 7 pushes the molten material downward, it will be transmitted to the feeding component 2134, so that the feeding component 2134 can stably output power to the transmission rack 2133, and then the transmission rack 2133 moving back and forth will link the transmission teeth 2132, so that the split part 211 can rotate along the connection center of the bracket 2131 to open or close the discharge channel at the bottom.

[0073] It should also be added that in order to better achieve the locking of the accommodating component 21 by the locking block 3212, as shown in FIG. Figure 3 As shown, the bracket 2131 is provided with a locking space 21311 for the locking block 3212 to lock.

[0074] like Figure 4 As shown, the feed assembly 2134 includes: a feed screw 21341 that moves through the bracket 2131 and is threaded through the transmission rack 2133; a guide member 21342, the guide member 21342 installed on the bracket 2131 slides through the transmission rack 2133; and a linkage member 21343, the linkage member 21343 for rotating the feed screw 21341 is installed on the feed screw 21341.

[0075] In this embodiment, the downward power of the blanking component 7 will be linked to the linkage part 21343, thereby driving the feed screw 21341 to rotate, and then the transmission rack 2133 connected to the feed screw 21341 will move back and forth along the guide direction of the guide part 21342, thereby realizing the stable provision of feed power to the transmission rack 2133.

[0076] like Figure 6 As shown, the cover body 22 includes: a main body 221, and a plurality of exhaust spaces 222 are evenly distributed on the circumference of the main body 221; a sealing member 223 for sealing the exhaust space 222, and the sealing member 223 arranged corresponding to the fastener 214 is slidably installed on the main body 221.

[0077] In this embodiment, when the cover body 22 is placed on the accommodating component 21, it is locked to the seal 223 through the upper cover component 5, and can slide back and forth on the main body 221 with the seal 223 to achieve the sealing of the exhaust space 222 after the exhaust is completed. At the same time, the seal 223 will also be locked under the fastener 214 to complete the locking of the accommodating component 21.

[0078] It is also necessary to add that Figure 12 and 13 As shown, the upper cover assembly 5 includes a transfer seat 51, an upper cover driving seat 52 provided below the transfer seat 51, an upper cover lifting motor 53 installed on the transfer seat 51 and with a power end connected to the upper cover driving seat 52, a transverse movement motor 54 provided on the frame 1 and with a power end connected to the transfer seat 51, a cover pushing motor 55 circumferentially arranged at the bottom of the upper cover driving seat 52, and a cover pushing seat 56 installed on the push rod motor 55.

[0079] In this embodiment, when it is necessary to lock the cover body 22, the transverse movement motor 54, which is preferably a push rod motor, drives the transfer seat 51 to the top of the accommodating component 21, and then the upper cover lifting motor 53, which is preferably a push rod motor, drives the upper cover driving seat 52 to move up and down, so that the push cover seat 56 is inserted into the protrusion to be locked of the seal 223, and the push cover motor 55, which is preferably a push rod motor, moves the seal 223 back and forth through the push cover seat 56 to open or close the exhaust space 222.

[0080] In order to better realize the opening of the exhaust space 222, the cover 22 can be removed. Figure 6 and 13As shown, the middle of the main body 221 is provided with a T-shaped seat 224. When the cover pushing seat 56 pushes the exhaust space 222 with the seal 223, the cover pushing seat 56 reaches the bottom of the T-shaped seat 224, and then under the power of the upper cover lifting motor 53, the cover body 22 is moved upward away from the accommodating component 21.

[0081] It should also be noted that the lower cover assembly 6 can adopt the same specific implementation structure as the upper cover assembly 5. When the cover body 22 is removed, the sealing member 223 is driven to open the exhaust space 222, which will not be elaborated here.

[0082] like Figure 10 As shown, the blanking component 7 includes: a rotating disk 71 that is in transmission cooperation with the linkage member 2134; a power pusher 72, which is installed in the middle of the bottom of the rotating disk 71 to push the annular sheet-shaped melt in the accommodating component 21 downward; a lifting power member 73 for driving the rotating disk 71 to move up and down; and a rotating power member 74 for driving the rotating disk 71 and the power pusher 72 to rotate.

[0083] In this embodiment, the rotating disk 71 is driven to rotate by the power of the rotating driving member 74, which is preferably a servo motor, and when it descends to contact the linkage member 21343 under the power of the lifting power member 73, which is preferably a cylinder, it is transmitted to the linkage member 21343, thereby driving the split member 211 to open or close. When opening, the power push member 72 will also follow the rotation and press onto the annular sheet of molten material, rotating the molten material to separate from the inner wall of the split member 211 while pushing it downward away from the accommodating chamber 212.

[0084] It should be supplemented that the rotating disk 71 is preferably a gear disk structure, and the linkage member 21343 is preferably a gear structure.

[0085] It should also be added that the power pushing member 72 includes a pushing power member 722 installed on the rotating disk 71 and a pressing member 721 installed on the power end of the pushing power member 722 .

[0086] In this embodiment, the pushing power member 722 , which is preferably a cylinder, drives the pressing member 721 to exert a pushing pressure on the molten material in the accommodating component 21 .

[0087] Example 3

[0088] like Figure 14 As shown, a method for detecting the total boron content of a device for testing the boron content in a boron-containing carbon material comprises the following steps:

[0089] Step 1: Loading and exhausting: weigh the boron-carbon ash material into the accommodating component 21, add anhydrous calcium carbonate and potassium nitrate, stir evenly, and then place it on the cooling component 32. The upper cover component 5 installs the cover body 22 onto the accommodating component 21, and opens the exhaust space 222 for exhausting;

[0090] Step 2: Heating and melting. The upper cover assembly 5 closes the exhaust space 222 after exhaust and then evacuates. The transfer assembly 31 sends the charging assembly 2 into the melting assembly 4 for melting and then takes it out.

[0091] Step 3: Oblique cooling: the cooling assembly 32 drives the removed charging assembly 2 to be arranged obliquely, and at the same time, the obliquely arranged charging assembly 2 is continuously rotated and cooled, so that the molten material is condensed into annular sheets;

[0092] Step 4: Discharging: Remove the cover 22 from the lower cover assembly. The rotating power member 74 drives the lifting power member 73 to drive the rotating disk 71 downward to contact the linkage member 21343, so that the feed screw 21341 drives the transmission rack 2133 to transmit to the transmission gear 2132, so that the split member 211 opens to discharge the annular sheet frit. At the same time, the power push member 72 pushes the annular sheet frit downward to separate from the split member 211.

[0093] Step 5, determination, the annular flake frit and the split part 211 formed in step 4 are pushed into a beaker filled with hydrochloric acid, shake the beaker to dissolve it quickly, and then dilute it with water to the scale; transfer the constant volume to another beaker, dilute it with water, add a drop of methyl red, add calcium carbonate in batches and stir until no carbon dioxide emerges; heat and boil, filter, and collect the filtrate in a conical flask; add hydrochloric acid dropwise until the solution turns red, boil, cool to room temperature, and titrate with a standard sodium hydroxide solution until it turns yellow; add phenolphthalein indicator and mannitol, add sodium hydroxide standard solution dropwise until it turns slightly red, then add a small amount of mannitol. If the red color disappears, add sodium hydroxide solution dropwise until it turns slightly red, and repeat this process until the slightly red color does not fade after adding mannitol. The volume of sodium hydroxide solution consumed is recorded as V (blank deducted);

[0094] The calculation formula is: total boron content W=5*10.81CV*100 / m*1000; C----concentration of sodium hydroxide standard solution, unit: mol / L; 10.81----molar mass of boron, unit: g / mol.

[0095] This process reduces the amount of auxiliary equipment required for measurement, simplifies the measurement process, and greatly improves the accuracy and efficiency of boron content testing.

[0096] Example 4

[0097] A method for testing the total boron content in a boron-containing carbon material comprises the following steps:

[0098] 1) Weigh a sample of corresponding weight according to the ash content of the boron-containing carbon material and place it in the containing component 21, and record the mass as m;

[0099] 2) Add 3.0g of anhydrous sodium carbonate and 0.1g of potassium nitrate, stir evenly, then add 1.0g of anhydrous sodium carbonate. Use the feeding assembly 5 to control the exhaust space 222 on the cover 22 to open, allowing the decomposed gas to escape;

[0100] 3) Place the container assembly 21 into the smelting assembly 4 and heat at 650°C for 2 hours, 700°C for 1 hour, and 750°C for 1 hour, and then heat to 900°C for 30 minutes;

[0101] 4) Tilt and rotate the container assembly 21 so that the melt adheres to the wall of the container assembly 21 in the form of annular sheets. After cooling, discharge the frit in the container assembly 21 through the discharge assembly 7 into a 250ml beaker containing 100ml of hydrochloric acid solution. Shake the beaker continuously to quickly dissolve the frit. After dissolution, transfer the frit to a 250ml volumetric flask and dilute it to the mark with water.

[0102] 5) Use a pipette to transfer 50 ml of the dilution solution to a 250 ml beaker, dilute with water to 70-80 ml, add one drop of methyl red, and gradually add calcium carbonate and stir until no more carbon dioxide is emitted.

[0103] 6) Heat and boil for 5-10 minutes, filter with medium-speed filter paper, collect the filtrate in a 500ml conical flask, wash the beaker with hot water 3-4 times, and precipitate 10-12 times, until the concentrated volume is about 160ml;

[0104] 7) Add hydrochloric acid until the solution turns red, boil for 5-10 minutes, cool to room temperature, and titrate with standard sodium hydroxide solution until it turns yellow;

[0105] 8) Add 10 drops of phenolphthalein indicator and 2-3g of mannitol. Add standard sodium hydroxide solution until the color turns slightly red. Then add a small amount of mannitol. If the red color disappears, add more sodium hydroxide solution until the color turns slightly red. Repeat this process until the red color persists after adding mannitol. The volume of sodium hydroxide solution consumed is recorded as V (after deducting the blank).

[0106] The calculation formula is: total boron content W=5*10.81CV*100 / m*1000; C----concentration of sodium hydroxide standard solution, unit: mol / L; 10.81----molar mass of boron, unit: g / mol.

[0107] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
