Description

Technical Field

[0001] The utility model belongs to the field of sulfur content measurement in mining industry and relates to a sampling and setting out tool in the sulfurization process. Background Art

[0002] When the ore contains sulfur and the sulfur content needs to be determined, the combustion neutralization method can be used to determine the sulfur content. Determination principle: The sample is burned in air at 1150-1250℃. After the sulfur in sulfide and sulfate is converted into sulfur dioxide, it is absorbed and oxidized into sulfuric acid with hydrogen peroxide solution. A mixed solution of methyl red and methylene blue is used as an indicator and titrated with a sodium hydroxide standard solution. The sulfur content is calculated based on the sodium hydroxide consumption. When the sample is sent into the furnace of the electric furnace, the approximate position of the porcelain boat is judged by the naked eye. The position of the magnetic boat is not necessarily in the center of the furnace, so the required temperature may not be reached, resulting in incomplete combustion of the sample and affecting the test results.

[0003] The combustion neutralization method is used to determine the sulfur content. The sample needs to be fully burned in the air at 1150-1250℃. Because the temperature at different positions in the electric furnace tube is different, only the temperature at the center of the tube can reach the set temperature. Therefore, the sample can be fully burned when placed in the center. If the sample is not fully burned, it will affect the accuracy of the test results and make the results low. In the past test process, the naked eye was used to judge whether the porcelain boat containing the sample was placed in the center, which was not accurate and time-consuming, which not only affected the test results but also greatly reduced the efficiency of the test.

[0004] Therefore, in order to place the porcelain boat in the center more accurately, a matching tool is needed. Utility Model Content

[0005] The present application provides a sampling and placing tool during a vulcanization process, which can accurately place a porcelain boat in the center of an electric furnace tube.

[0010] As an improved technical solution of the present application, the diameter of the ring is 0.8-1 cm.

[0011] As an improved technical solution of the present application, the size of the hook head is a No. 4 steel wire bent 75 degrees to form a hook shape.

[0024] The present application designs an auxiliary tool that can simply, quickly and accurately push the porcelain boat containing the sample to a specific position, reducing the possibility of low sulfur test results due to incomplete combustion caused by temperature reasons. The supporting tool includes a layout tool and a sampling tool. The layout tool sets the position marking line, and the layout tool goes deep into the furnace tube to reach the marking line, that is, the porcelain boat is in the center of the furnace. The sampling tool is convenient for the porcelain boat to be quickly taken out of the furnace tube.

[0026] like Figure 1 , Figure 4 as well as Figure 5 As shown, a layout tool 8 for vulcanization process, a rod body 82, a rod head and a rod tail (handle 84); the rod head is perpendicular to the rod body 82. The total length of the rod body 82, the rod head (ring 81) and the rod tail (handle 84) is greater than the pipe length of the tubular electric furnace; the rod body is provided with a mark 83 at a position consistent with the center length of the pipe of the tubular electric furnace, and the use of the mark 83 ensures that when the marked position is reached during the layout process, the magnetic boat 7 also reaches the specified position. In the use state, the ring 81 can support the end of the magnetic boat 7 to facilitate the pushing of the magnetic boat 7. The rod body 82, the rod head and the rod tail are all made of steel wire, preferably No. 4 steel wire.

[0027] Preferably, the circle 81 has a diameter of 0.8-1 cm, and the top width of the magnetic boat 7 is about 1 cm, so the size of the circle 81 is designed to fit the top width of the magnetic boat 7 for easy pushing.

[0028] The rod tail is provided with a handle 84, and the handle 84 is an arc-shaped structure.

[0029] Example 2

[0030] like Figure 2 , Figure 3 and Figure 6 As shown, a sampling tool 9 for vulcanization process comprises a rod body 92, a rod head and a rod tail (handle 93); the rod head and the rod body are hooked at 75 degrees. The rod head is provided with a hook head 91 matching the porcelain boat 7; the hook head 91 can hook the hole 10 at the top of the magnetic boat 7 to facilitate pulling out the magnetic boat 7. The rod body 92, the rod head and the rod tail are all made of steel wire.

[0031] The hook head 91 is formed by bending a No. 4 steel wire at 75 degrees to form a hook shape. The top of the magnetic boat 7 has a hole 10 with a diameter of about 6 mm.

[0032] In this embodiment, the sampling tool uses No. 4 steel wire. The sampling tool bends a section of the steel wire into a 75-degree hook (hook shape). The hook can just hook the hole 10 at the top of the magnetic boat 7, and then quickly drag the magnetic boat 7 out in a straight line into the magnetic boat 7 recovery tray placed at the circuit port.

[0033] The rod tail is provided with a handle 93; the handle 93 is an arc-shaped structure.

[0034] Example 3

[0035] like Figure 3 and Figure 4 shown.

[0036] Step 1: Determine the material and shape of the layout tool 8 and the removal tool 9.

[0037] 1. The layout tool 8 uses No. 4 steel wire, which is the rod. One end of the rod (rod head) is made into a circle 81 with a diameter of 0.8-1.2 cm, which is convenient for pushing the porcelain boat 7; the other end (rod tail) is made into an arc-shaped handle 84 that is easy to hold; the middle section is the rod body 82.

[0038] 2. The removal tool 9 is made of No. 4 steel wire, which is the rod. One end of the rod (rod head) is made into a hook head 91, so that it can hook the hole 10 at one end of the porcelain boat 7 to pull the porcelain boat 7 out of the furnace tube; the other end (rod tail) is made into an arc-shaped handle 93 that is easy to hold; the middle section is the rod body 92.

[0039] Step 2: Determine the position marking line (mark 83) of the layout tool 8.

[0040] 1. Preliminarily determine the sample delivery position marking line (mark 83). According to the pipe length of the existing equipment tubular electric furnace (double tube), a 50cm long steel wire is initially selected to push the porcelain boat 7 containing the sample (sulfur standard sample) into the furnace, and then observe the position of the porcelain boat 7. Observe with the naked eye whether the porcelain boat 7 has reached the center. After slowly adjusting to the center, use a pen to mark the position of the cross-section of the pipe mouth with the steel wire. This marking line is the mark 83 of the sample delivery position 5. Among them, the furnace is located in the box 6, and the external power supply provides energy to the heating tube 4 in the furnace through the power cord 1. The box 6 is provided with heat dissipation holes 2 to prevent the box 6 from overheating.

[0041] 2. Further determine the mark 83 of the sample delivery position 5. According to the initially determined sample delivery position, perform 10 sets of parallel tests. Each set of experimental samples is pushed to the sample delivery position 5 by the above-mentioned tool, and then the subsequent experimental steps are performed to complete the determination of sulfur. The 10 sets of experimental results are compared with the standard sample. If they can all reach the error range of the standard sample, it is determined that the position mark line of the pushing tool 8 is accurate, otherwise continue to adjust the mark 83 until all the experimental results are within the standard error range.

[0042] Step 3: Making the layout tool 8 and the removal tool 9.

[0043] The material and shape are completed according to step 1, and the length of the marking position determined in step 2 is extended by 15-20cm to obtain the total length of the layout tool 8 or the sampling tool 9. The total length of the tool is appropriately extended by 15-20cm to obtain the length of the marking line, which is more convenient to use. And make a clear mark 83 at the corresponding position of the layout tool 8, which is the position marking line. The total length of the sampling tool 9 = the total length of the layout tool 8.

[0044] Usage process: Step description, unplug the piston 3 at the nozzle of the heating tube 4, put the magnetic boat 7 with the sample into the nozzle of the heating tube 4, use the sample placement tool 8 to send the magnetic boat 7 to the specific sample delivery position 5 in the furnace, and then plug the piston 3 to conduct the experiment. After the experiment is completed, pull out the piston 3, use the hook 91 of the extraction tool 9 to assist in removing the magnetic boat 7, and complete the experiment.

[0045] In summary, the tools for pushing and taking out the magnetic boat designed in this application are used in combination. When testing sulfur, the magnetic boat containing the sulfur sample is placed into the pipe mouth of the electric furnace (the pipe mouth of the heating tube 4), and then the magnetic boat 7 is pushed into the furnace by the placement tool 8, and it is ready when the placement tool 8 penetrates to the mark 83. After the test is completed, the magnetic boat 7 is taken out by the sampling tool 9.
