Description

Technical Field

[0001] The utility model relates to a sample bag making component, in particular to a coal sample bag making component for an infrared hydrocarbon analyzer, and belongs to the technical field of production and manufacturing of coal detection auxiliary devices. Background Art

[0002] Usually, the content of carbon and hydrogen elements in coal is determined by using an infrared carbon and hydrogen analyzer.

[0003] Infrared hydrocarbon analyzers are also called infrared hydrocarbon testers or infrared hydrocarbon element analyzers. Existing infrared hydrocarbon analyzers usually consist of four parts: extraction unit, purification unit, detection unit, and data processing unit. Of course, they also include additional auxiliary gas circuits, including:

[0004] The extraction unit converts the carbon and hydrogen elements in the coal sample into a form that can be detected by the detector. The commonly used method is to heat the coal sample, causing it to melt and burn in an oxygen atmosphere, so that the carbon element in the coal sample is converted into carbon dioxide and carbon monoxide, and the hydrogen element is converted into water vapor. Therefore, the extraction unit is also called the heating unit. In the past, electric arc furnace heating was used. Currently, the mainstream infrared carbon and hydrogen analyzers use high-frequency induction heating or resistance furnace heating.

[0005] The purification unit is used to purify oxygen and combustion gas, and the so-called combustion gas is carbon dioxide, carbon monoxide and water vapor;

[0006] The detection unit converts the concentration of the measured component into a signal that can be processed by the subsequent data processing unit. Generally, it refers to an electrical signal, including voltage, current or resistance. The detection method adopted by the infrared hydrocarbon analyzer is the infrared absorption method, that is, two infrared absorption cells are connected in series, and carbon dioxide gas and water vapor are allowed to absorb the specific wavelength infrared rays corresponding to their respective absorption in the two infrared absorption cells. At the same time, the intensity of the specific wavelength infrared rays before and after being absorbed by carbon dioxide gas and water vapor in the two infrared absorption cells is detected.

[0007] The data processing unit generally uses a single-board computer or a computer for processing, that is, the electrical signal generated by the two specific wavelength infrared intensities collected by the detection unit is converted into a digital signal through an A / D converter, and then the single-board computer or computer performs calculations to finally obtain the respective contents of carbon and hydrogen elements in the tested coal sample.

[0008] Specifically, the infrared carbon hydrogen analyzer mainly includes the following processes and steps to determine the content of carbon and hydrogen elements in coal:

[0009] First, the coal sample to be tested is placed in a high-temperature furnace at a temperature of 950°C. Oxygen is then introduced to cause the coal sample to burn rapidly. The resulting combustion gas is introduced into a secondary furnace at a temperature of 850°C for further oxidation treatment to achieve complete combustion. This means that the carbon in the coal sample is completely converted into carbon dioxide gas, and the hydrogen in the coal sample is completely converted into water vapor. During this process, dust particles are removed through a purification unit.

[0010] Afterwards, the completely burned gas is collected in a gas storage tank and fully mixed in the gas storage tank to ensure uniform mixing. When the gas in the gas storage tank reaches a stable and balanced state, the quantitative valve is activated to introduce the carbon element in the tested coal sample into the carbon infrared cell in the form of carbon dioxide gas for absorption and detection. At the same time, the hydrogen element in the tested coal sample is introduced into the hydrogen infrared cell in the form of water vapor for absorption and detection.

[0011] In two different infrared cells, the emitted infrared light is absorbed by carbon dioxide gas and water vapor respectively. Then, the computer converts the energy signal on the detector into a digital signal through an (A / D) converter. After curve correction, the carbon and hydrogen content in the coal sample is finally calculated.

[0012] To ensure the accuracy of the test, usually, the coal samples need to be processed with tinfoil before the test, that is, the coal samples are wrapped with tinfoil into a water drop shape, and then placed one by one into the sample package hole of the infrared hydrocarbon analyzer's sample tray, and then the coal samples wrapped in water drop shape are allowed to enter the extraction unit of the infrared hydrocarbon analyzer from the sample package hole for combustion. Figure 1 Schematic diagram of the coal sample bag production process for carbon and hydrogen element content detection in the prior art, and Figure 2 In the prior art, when using an infrared carbon hydrogen analyzer to detect the carbon and hydrogen content in a coal sample, the coal sample bag placement process is as shown in the schematic diagram to ensure the integrity and certainty of the coal sample during the test process.

[0013] from Figure 1 It can be seen that in the prior art, the wrapping process of the coal sample of the infrared hydrocarbon analyzer mainly includes: placing the tinfoil 1 on the coal sample holder 2 with a concave hole, then putting the coal sample 4 to be tested into the tinfoil 1 through the sample spoon 3, and then manually twisting the upper part of the tinfoil 1 containing the coal sample 4 to form a closed teardrop-shaped coal sample package 5.

[0014] from Figure 2 It can be seen that in the prior art, the extraction unit 20 of the infrared hydrocarbon analyzer is usually arranged on one side of the main unit 10 of the infrared hydrocarbon analyzer, which includes a purification unit, a detection unit and a data processing unit. The extraction unit 20 is also provided with a rotatable sample tray 21, and the teardrop-shaped coal sample bags 5 are manually placed one by one into the sample bag holes of the sample tray 21 using tweezers.

[0015] The specific beneficial effects of processing the coal samples to be tested into closed teardrop-shaped coal sample bags are as follows:

[0016] 1. Prevent coal samples from being contaminated. By wrapping them in tinfoil, the coal samples can be prevented from being directly exposed to the environment, thereby reducing the adhesion of dust and pollutants and ensuring the purity of the coal samples. At the same time, during the sampling and weighing process, the closed environment formed by the tinfoil can effectively isolate the interference of external gas and moisture, thereby ensuring the accuracy of the test;

[0017] 2. Ensure the uniformity of the coal sample, that is, by wrapping the coal sample into a teardrop shape and twisting the opening of the tinfoil to form a closed coal sample package, not only can the distribution of the coal sample components in the coal sample package be more uniform, which is conducive to improving the consistency and repeatability of the analysis, but also the uniform distribution of coal sample particles in the tinfoil also helps to fully and evenly burn the coal sample during high-temperature combustion, thereby ensuring the stability and accuracy of the measurement results;

[0018] 3. Promote the complete combustion of coal samples. During infrared hydrocarbon element analysis, the combustion of coal samples needs to be carried out under high temperature and oxygen-rich conditions. Wrapping the coal samples in tinfoil is conducive to instantaneous combustion of the coal samples at high temperature, promoting the complete decomposition of the coal samples. At the same time, for coal samples that are difficult to completely decompose, the presence of tinfoil also facilitates the further use of the "instantaneous combustion + complete combustion" combination method to promote their full combustion, thereby ensuring the complete decomposition of the coal samples.

[0019] 4. Avoid the loss of coal samples, because the coal samples formed a closed system after being wrapped in tinfoil, which can effectively prevent the loss of coal sample particles during the combustion process. This is especially important when dealing with small amounts of coal samples. Only in this way can we ensure that the amount of coal sample is not lost during the entire analysis process, thereby reducing the measurement error caused by changes in coal sample quality;

[0020] 5. Keep the testing instrument clean. Obviously, after wrapping the coal sample with tinfoil, the residue produced by its combustion is easier to clean, thereby avoiding the contamination of the instrument by the coal sample residue and keeping the instrument clean and accurate. At the same time, tinfoil is a disposable wrapping material and can be discarded after use, thereby simplifying the cleaning and maintenance operations of the instrument.

[0021] However, the existing infrared carbon hydrogen analyzer has coal sample packages such as Figure 1 As shown, all of this is done manually. This packaging method has at least the following shortcomings:

[0022] 1) When wrapping the coal sample into a water drop shape with tin foil, the operator cannot Figure 1Instead of operating with bare hands as shown in the figure, rubber gloves must be worn to prevent sweat or other dirt on the hands from coming into contact with the tin foil, so as to avoid contaminating the coal sample and affecting the accuracy of the experiment. However, it is well known that wearing rubber gloves for a long time may cause discomfort to the hands or even cause rashes, and frequent wearing and taking off of gloves will also reduce work efficiency.

[0023] 2) Even if the same operator performs the wrapping operation, there will be certain shape differences between the coal samples obtained by wrapping, and this individual difference will become a potential source of deviation in the test results;

[0024] 3) When the coal sample is wrapped into a water drop shape, the external surface area of ​​the coal sample is similar to that of a sphere. However, the surface area of ​​a sphere is obviously much smaller than that of a cylinder of the same volume, which will affect the combustion efficiency to a certain extent.

[0025] 4) After the coal sample is wrapped into a water drop shape and placed in the sample tray of the infrared hydrocarbon analyzer, as the sample tray rotates, the tail of the water drop-shaped coal sample, that is, the opening and twisting closure of the tinfoil, may sometimes get stuck in the gap at the bottom of the turntable of the sample tray. This will not only cause the turntable to get stuck, but sometimes may also force the experiment to terminate early. Utility Model Content

[0078] The technical solution of the present utility model is described in detail below with reference to specific embodiments.

[0079] Example

[0080] This embodiment provides an infrared carbon hydrogen analyzer coal sample bag production component for wrapping and sealing a coal sample with tin foil to form a coal sample bag when detecting the carbon and hydrogen content of the coal sample through an infrared carbon hydrogen analyzer, wherein the infrared carbon hydrogen analyzer has an extraction unit, a rotatable sample placement plate is provided on the extraction unit, and a sample bag hole for placing the coal sample bag is also provided on the sample placement plate.

[0081] like Figure 3 A schematic diagram of the three-dimensional structure of a coal sample pack manufacturing component of an infrared carbon-hydrogen analyzer provided in an embodiment of the present invention, Figure 4 A schematic diagram of the three-dimensional structure of an optimized infrared carbon-hydrogen analyzer coal sample package manufacturing component provided by the embodiment of the utility model, Figure 5 The three-dimensional structural diagram of another optimized infrared carbon-hydrogen analyzer coal sample package manufacturing assembly provided by the embodiment of the utility model is shown as follows:

[0082] An infrared carbon-hydrogen analyzer coal sample bag production assembly, comprising:

[0083] Tin foil cup 100, tin cup seat 200 and sealing member, wherein:

[0084] The tin foil cup 100 is a barrel-shaped component, which is used to hold coal samples; the tin cup seat 200 is a block-shaped component, which is used to accommodate the barrel-shaped cup body of the tin foil cup 100; the sealing component is used to gather and seal the upper opening of the tin foil cup 100 to form a cylindrical coal sample package (not shown in the figure) wrapped with tin foil and enclosing the coal sample.

[0085] From the above description, we can see that:

[0086] The infrared hydrocarbon analyzer coal sample bag manufacturing assembly provided in this embodiment includes a tin foil cup, a tin cup holder, and a sealing member. The tin foil cup is a prefabricated barrel-shaped member for holding the coal sample. The tin cup holder is a block-shaped member for accommodating the cup body of the tin foil cup. The sealing member is used to close the upper opening of the tin foil cup, thereby forming a cylindrical coal sample bag wrapped with tin foil and enclosing the coal sample.

[0087] It can be seen that the infrared carbon hydrogen analyzer coal sample bag making component provided in this embodiment overcomes the shortcomings of the existing technology. During the process of making the coal sample bag, the operator does not have to directly touch the tin foil cup with his hands. Not only can the tin foil wrapping of the tested coal sample be completed quickly, standardized and efficiently, thereby improving the accuracy and consistency of carbon and hydrogen element detection of coal samples using the infrared carbon hydrogen analyzer, and reducing detection errors caused by human factors. At the same time, during the entire coal sample bag making process, the operator no longer needs to wear rubber gloves, which not only improves work efficiency, but also improves working conditions, and eliminates various discomforts or injuries that may be caused to the operator due to wearing rubber gloves for a long time.

[0088] Optionally, in this embodiment, the tinfoil cup 100 can be made of tinfoil by stamping or stretching.

[0089] Since the tin foil cup in the infrared hydrocarbon analyzer coal sample bag production assembly provided in this embodiment is a prefabricated barrel-shaped component made by stamping or stretching, and its opening is sealed with a sealing member, the operation is not only simple and quick, but also the resulting coal sample bag has a standardized shape with minimal variation, which can effectively eliminate the deviation in test results caused by individual differences in coal sample bags;

[0090] The cylindrical coal sample bag has a larger external surface area than the teardrop-shaped coal sample bag in the existing technology that is similar to a sphere. Therefore, under the same conditions, the combustion efficiency can be improved. The cylindrical coal sample bag also eliminates the problem of being stuck in the gap at the bottom of the turntable of the sample feed tray, so there is no need to worry about the turntable getting stuck, thereby ensuring the normal and smooth progress of the experiment. Compared with the existing technology, it has substantial progress and positive significance, so it is of great value for promotion and application.

[0091] Optional, such as Figure 6 The cross-sectional structure diagram of the tin cup seat with blind holes provided by the embodiment of the present invention is as follows:

[0092] The tin cup seat 200 can form an accommodating hole 211 through a blind hole provided thereon to accommodate the barrel-shaped cup body of the tin foil cup 100 .

[0093] Obviously, such a tin cup holder has an extremely simple structure, is extremely easy to make and use, and does not require complicated maintenance and care, but the effect is obviously reliable.

[0094] Optimized, such as Figure 7 The cross-sectional structure diagram of the tin cup seat with a through hole is shown in the following figure:

[0095] The tin cup holder 200 includes a main body and a pull-out plate 212. The main body is provided with a through hole, and the pull-out plate 212 is arranged in the middle of the through hole. The pull-out plate 212 divides the through hole into an upper accommodating hole 211 and a lower outlet hole 213. The accommodating hole 211 is used to accommodate the barrel-shaped cup body of the tin foil cup 100, and the outlet hole 213 is used to align with the sample package hole on the sampling plate 21 of the extraction unit of the infrared hydrocarbon analyzer to thereby place the coal sample package.

[0096] Obviously, although such a tin cup holder is slightly complicated, it is very convenient to take out the coal sample bag, that is, the coal sample bag can be guided out of the tin cup holder by simply pulling the pull plate;

[0097] Furthermore, the tin cup holder containing the coal sample package is placed on the sample placement plate of the extraction unit of the infrared hydrocarbon analyzer, and the lead-out hole is aligned with the sample package hole. By pulling the pull-out plate, the coal sample package can be led out of the tin cup holder and directly into the sample package hole. There is no need to manually place the coal sample package into the sample package hole with tweezers, so it is more convenient and quick.

[0098] Furthermore, the main body of the tin cup holder 200 having a through hole can be made of a magnetic material, and when the sampling disk 21 of the extraction unit of the infrared hydrocarbon analyzer is made of a non-ferromagnetic material, the tin cup holder 200 also includes a buckle plate (not shown in the figure) that can be buckled onto the surface of the sampling disk 21. The buckle plate has a shape and structure consistent with the upper surface of the sampling disk 21, and the buckle plate is made of a ferromagnetic material.

[0099] Obviously, the tin cup seat body with a through hole made of magnetic material can be directly placed on the sampling disk of the extraction unit of the ferromagnetic infrared hydrocarbon analyzer or the buckle plate on the surface of the ferromagnetic sampling disk through magnetic force. In this way, the tin cup seat can be more conveniently placed on the sampling disk of the extraction unit of the infrared hydrocarbon analyzer, so that the coal sample package can be easily and quickly introduced into the sample package hole.

[0100] Further, such as Figure 4 As shown, the infrared hydrocarbon analyzer coal sample package production assembly provided in this embodiment also includes a funnel 400, the bottom of the funnel 400 can be placed on the cup mouth of the tinfoil cup 100, and the funnel 400 is used to introduce the coal sample into the interior of the tinfoil cup 100.

[0101] like Figure 3 、 Figure 4 and Figure 8 The three-dimensional structure diagram of the sealing component composed of the T-shaped component of the infrared carbon hydrogen analyzer coal sample package manufacturing assembly provided by the embodiment of the utility model is shown as follows:

[0102] The sealing member can be a T-shaped member 310 formed by connecting a pressing plate 311 and a connecting rod 312. The pressing plate 311 is circular or rectangular, and the diameter of the circular pressing plate 311 or the diagonal length of the rectangular pressing plate is not greater than the diameter of the cup mouth of the tin foil cup 100.

[0103] Obviously, such a sealing component has an extremely simple structure, is extremely convenient to manufacture and use, and does not require complicated maintenance and care, but is obviously effective and reliable.

[0104] Further, from Figure 8 It can be seen that the optimized connecting rod 312 is further provided with a pinching portion 312a in the middle thereof. The pinching portion 312a is a flat structure and has anti-slip grooves on the surface. The free end 312b of the connecting rod 312 that is not connected to the pressure plate 311 is shovel-shaped, and the shovel-shaped free end 312b is used to gather and close the upper opening of the tin foil cup 100.

[0105] Obviously, the improved sealing component is more convenient to use and does not require complicated maintenance and care, but the effect is more obvious and reliable.

[0106] like Figure 9 The present invention provides an infrared carbon hydrogen analyzer coal sample pack manufacturing assembly, wherein the sealing member formed by the screw closing device is a top view of the three-dimensional structure diagram, as shown in FIG. Figure 10 The bottom-up perspective structural diagram of the sealing member formed by the screw-closer of the infrared carbon-hydrogen analyzer coal sample bag manufacturing assembly provided by the embodiment of the utility model is shown as follows:

[0107] In the infrared hydrocarbon analyzer coal sample package production assembly provided in this embodiment, the sealing component can also be a screw-closer 320, which is installed on the upper part of the tin cup seat 200. The screw-closer 320 is used to close the upper opening of the tin foil cup 100 by rotating.

The plurality of slots 321b are evenly distributed around the periphery of the hole 321a.

[0112] The screw cap 322 is provided with a screw cap tin cup hole 322a and a rectangular screw cap chute 322b. The screw cap tin cup hole 322a is used to fit the opening of the cup body of the tin foil cup 100. The plurality of screw cap chute 322b are evenly distributed around the outer periphery of the screw cap tin cup hole 322a.

[0113] The butterfly piece 323 has a lower protrusion 323a on its lower side that can be inserted into the butterfly disc sliding groove 321b, and an upper protrusion 323b on its upper side that can be inserted into the rotary cover sliding groove 322b.

The butterfly piece group is arranged between the butterfly disc 321 and the rotary cover 322, and each butterfly piece 323 is inserted into the butterfly disc sliding groove 321b and the rotary cover sliding groove 322b respectively through its respective lower protrusion 323a and upper protrusion 323b;

[0114] By rotating the rotary cover 322, the butterfly pieces 323 in the butterfly piece assembly can be rotated and gathered together in sequence, thereby closing the cup body of the tin foil cup 100 located above the tin cup hole 321a of the butterfly plate.

[0115] The ratchet locking mechanism includes a chassis 324, a ratchet disc 325 and a pawl 326;

[0116] The bottom plate 324 has a through bottom plate tin cup hole 324a in the middle thereof, and the bottom plate tin cup hole 324a is used to insert the cup body of the tin foil cup 100. The bottom plate 324 also has a fan-shaped bottom plate slide groove 324b, and a plurality of bottom plate slide grooves 324b are evenly distributed around the outer periphery of the bottom plate tin cup hole 324a.

[0117] The ratchet 325 has a through ratchet tin cup hole 325a in the middle thereof, which is used to fit the cup body of the tin foil cup 100. The upper side of the ratchet 325 is an inner ratchet 325b, and a through rectangular ratchet slot 325c is provided in the inner ratchet 325b. Figure 12(not shown), a protruding slider 325d is provided on its lower side, multiple sliders 325d are evenly distributed on the outer periphery of the ratchet tin cup hole 325a, multiple ratchet slide grooves 325c are evenly distributed between the sliders 325d, and the ratchet 325 is rotatably provided on the chassis 324 by inserting its slider 325d into the chassis slide groove 324b;

The pawls 326 are movably arranged inside the inner ratchet plate 325b by having their lower legs 326a inserted into the ratchet plate slot 325c.

[0119] By rotating the butterfly disc 321 , the cam 321 c drives the pawl 326 to rotate in one direction and the pawl 326 is inserted into the ratchet teeth of the inner ratchet disc 325 b , thereby locking the butterfly disc 321 on the ratchet disc 325 and preventing it from rotating in the opposite direction.

[0120] From the above description, it can be seen that although the structure of the screw-on sealer is much more complicated than that of the T-shaped component, the upper opening of the tinfoil cup containing the coal sample can be directly gathered and closed by rotating the screw-on sealer, and the operator does not need to use the T-shaped component to manually gather and close the opening of the tinfoil cup. Therefore, work efficiency can be greatly improved, and the gathering and closing operation can be more standardized, and the resulting coal sample package can also be more uniform and regular.

[0121] In summary, we can see that:

[0122] The utility model forms a novel infrared carbon hydrogen analyzer coal sample bag production component through a tin foil cup, a tin cup seat and a sealing component, which overcomes the shortcomings of the existing technology. Not only can the tin foil wrapping of the tested coal sample be completed quickly, standardized and efficiently, but the operator does not have to wear rubber gloves, eliminating various discomforts or injuries caused by rubber gloves, improving work efficiency and working conditions, and the obtained coal sample bag has a standardized shape and small differences, which can effectively eliminate the test deviation caused by individual differences in the coal sample bags, thereby improving the accuracy and consistency of using the infrared carbon hydrogen analyzer to detect carbon and hydrogen elements in coal samples, improving combustion efficiency, and ensuring the normal progress of the experiment. Moreover, the whole set of coal sample bag production components has a simple structure, is easy to make and use, is easy to maintain, has obvious and reliable effects, and has substantial progress and positive significance compared with the existing technology, so it has great promotion and application value.
