Description

Technical Field

[0001] The present invention relates to the technical field of atmosphere sampling, in particular to a high-temperature kiln atmosphere sampling and analysis system. Background Art

[0002] The high-temperature kiln is used to collect the positive electrode materials of waste lithium batteries. The black powder is adhered to the aluminum sheet, and the purpose of the high-temperature kiln is to remove the black powder from the aluminum sheet and then collect it. At the same time, it is also necessary to detect that the aluminum content in the mixture of black powder and gas in the high-temperature kiln shall not exceed 400 ppm.

[0003] There are several problems with existing high-temperature kiln atmosphere sampling equipment: 1. When the kiln body rotates, traditional sampling equipment will cause the material to roll and intermittently cover the sampling port, or cause volatile matter and dust to mix into the sampling airflow, resulting in instantaneous fluctuations in composition; 2. The gas in the kiln is a flowing gas, and traditional sampling equipment can only sample and process gases that flow faster or fluctuate more, ultimately resulting in certain limitations in detection and analysis.

DETAILED DESCRIPTION

[0058] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0059] See also Figures 1 to 14 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes a rotary kiln 1 for degumming black powder on aluminum sheets, and a roller seat 3 is installed on the outer transmission of the rotary kiln 1;

[0060] A baffle mechanism 9 for reducing the flow of air at the sampling port, the baffle mechanism 9 is arranged on the rotary kiln 1, and a fixing seat 2 is arranged on the outer side of the baffle mechanism 9;

[0061] A sampling mechanism 8 for performing multiple sampling processing on the gas inside the rotary kiln 1, the sampling mechanism 8 is arranged on the rotary kiln 1;

[0062] The sampling mechanism 8 is provided with a No. 1 air pipe 6 and a No. 2 air pipe 7, respectively. The ends of the No. 1 air pipe 6 and the No. 2 air pipe 7 away from the sampling mechanism 8 are fixedly connected to an air pump 5, wherein the number of the air pump 5 is two, and a control terminal is provided inside the air pump 5;

[0063] The air pump 5 is used to increase the sampling rate to avoid the sampling time being too long and affecting the subsequent detection accuracy.

[0064] The blocking mechanism 9 includes a connecting rod 91, the outer end of the connecting rod 91 is fixedly connected to the fixed seat 2, and the end of the connecting rod 91 away from the fixed seat 2 is fixedly connected to the adapter ring 92, and the adapter ring 92 is rotatably connected to the rotary kiln 1;

[0065] The adapter ring 92 is fixed and the rotary kiln 1 rotates;

[0066] The outer side of the adapter ring 92 is fixedly connected to the fixing base 2. A through hole 93 is formed on the top of the adapter ring 92. A ring support 94 is fixedly installed on the inner side of the adapter ring 92. A baffle 95 is rotatably installed inside the ring support 94. Elastic pieces 96 are fixedly connected to the tops of both ends of the baffle 95.

[0067] The elastic sheet 96 and the baffle 95 are used to prevent dust from entering the sampling port.

[0068] like Figure 6 、 Figure 7 and Figure 8 As shown, the sampling mechanism 8 includes an air inlet pipe 81, which is inserted into the top of the adapter ring 92 and extends to the inner side thereof. A through hole 82 is opened on the outer side of the air inlet pipe 81, wherein the through hole 82 is used to allow the sample gas to enter the interior of the air inlet pipe 81;

[0069] The outer side of the air inlet pipe 81 is slidably adapted with a leak-proof sleeve 83 , which is fixedly mounted on the top of the adapter ring 92 ;

[0070] The top of the leak-proof sleeve 83 is connected to the first infrared sensor 84 and the second infrared sensor 85 through rods.

[0071] Among them, the No. 1 infrared sensor 84 controls the vacuum pump 5 connected to the No. 1 air pipe 6, and the No. 2 infrared sensor 85 controls the vacuum pump 5 connected to the No. 2 air pipe 7; when the air inlet pipe 81 is reset, the equipment will all return to its original state, and at the same time, the embedded rod 86 will pass through the No. 1 infrared sensor 84 and the No. 2 infrared sensor 85 in reverse order, causing the two vacuum pumps 5 to stop vacuuming.

[0072] The outer side of the air inlet pipe 81 is fixedly connected with an embedded rod 86, which is fitted with the perforation 93 and squeezed with the baffle 95. First, from the internal perspective, the air inlet pipe 81 is driven downward by external power equipment and extends into the interior of the rotary kiln 1. A through hole 82 is provided on the outer side of the air inlet pipe 81, so the gas inside the rotary kiln 1 will enter the air inlet pipe 81 through the through hole 82. In addition, a patch 87 is fixedly connected to the inner side of the air inlet pipe 81, and the top of the patch 87 is connected to the vertical rod 88, wherein the top and outer side of the vertical rod 88 are respectively connected to the No. 1 sealing ring 100 and the column sleeve 108. Therefore, as the air inlet pipe 81 moves downward with the patch 87, the No. 1 sealing ring 100 and the column sleeve 108 will eventually move downward together, where the No. 1 sealing ring 100 seals the space surrounded by the outer transition pipe 101, the partition 102 and the inner transition pipe 103. However, as the No. 1 sealing ring 100 moves downward, the bottom of the space will be exposed, and the sampling gas passing through the through hole 82 will float into the space, thereby playing a role in transitional retention treatment for gases with faster flow rates and larger fluctuations, and also playing a role in allowing these sampling gases to be mixed more fully, thereby increasing the detection accuracy.

[0073] The top of the leak-proof sleeve 83 is fixedly connected to the fixed rod 80, and the top of the fixed rod 80 is fixedly connected to the telescopic ring 89. The output end of the telescopic ring 89 is fixedly connected to the air inlet pipe 81.

[0074] The inner side of the air inlet pipe 81 is fixedly connected with a patch 87, and the top of the patch 87 is fixedly connected with a vertical rod 88. From an external perspective, the outer side of the air inlet pipe 81 is slidably adapted with a leak-proof sleeve 83, wherein the function of the leak-proof sleeve 83 is to prevent the sampled gas from overflowing outwards from the through hole 82 again. In addition, the leak-proof sleeve 83 is fixedly mounted on the adapter ring 92, and the top of the leak-proof sleeve 83 is fixedly connected with a fixed rod 80, and the top of the fixed rod 80 is connected to the fixed end of the telescopic ring 89, wherein the telescopic ring 89 is a ring-type telescopic rod, and the output end of the telescopic ring 89 is connected to the air inlet pipe 81. Similarly, the function of the telescopic ring 89 is also to prevent the sampled gas from penetrating outwards. In addition, the outer side of the air inlet pipe 81 is fixedly connected with an embedded rod 86, so the embedded rod 86 will move downwards together. And pass through the No. 2 infrared sensor 85, at this time the No. 2 infrared sensor 85 will receive the signal that the embedded rod 86 moves downward, and then the No. 2 infrared sensor 85 will transmit the signal to the vacuum pump 5 connected to the No. 2 air pipe 7, wherein the control terminal is provided inside the vacuum pump 5, so the control terminal will judge the signal and control the vacuum pump 5 to perform vacuum processing, wherein the other end of the No. 2 air pipe 7 is connected to the peripheral sampling tube 113, and the other end of the peripheral sampling tube 113 is connected to the peripheral transition tube 101, so the vacuum pump 5 is used to completely draw the mixed sampling gas in the peripheral transition tube 101 into the peripheral sampling tube 113.

[0075] like Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown, the top of the fixed portion of the telescopic ring 89 is fixedly connected to a peripheral transition tube 101, and a partition 102 is fixedly connected to the interior of the peripheral transition tube 101, wherein the partition 102 divides the interior of the peripheral transition tube 101 into three chambers for sampling, detecting and processing the gas at different flow stages;

[0076] An inner transition tube 103 is fixedly connected to the central portion of the outer transition tube 101, wherein the outer transition tube 101 stores fluid gas, while the inner transition tube 103 stores non-fluid gas. In addition, a partition 102 is inserted into the top of the outer transition tube 101, and the interior of the outer transition tube 101 is divided into three chambers. At this time, there are two options: 1. Do not remove the partition 102, so that the outer sampling tube 113 will obtain sampling gases of three different flow time periods; 2. Remove the partition 102, so that the outer sampling tube 113 will obtain mixed sampling gases of different flow time periods.

[0077] The bottom of the inner transition pipe 103 is fixedly connected with an elastic reset rod 106, and the bottom end of the elastic reset rod 106 is fixedly connected with an extension block 105, and the outer side of the extension block 105 is fixedly connected with an inner sealing disk 109, which is slidably adapted inside the inner transition pipe 103 and is used to isolate the gas; as the bottom space of the inner transition pipe 103 is opened, the sampling gas with a slower flow rate will enter the inner transition pipe 103, and as the embedded rod 86 continues to move downward and is detected by the No. 1 infrared sensor 84, the No. 1 infrared sensor 84 will transmit the signal to the vacuum pump 5 connected to the No. 1 air pipe 6. At this time, the control terminal inside the vacuum pump 5 will judge the signal and control the vacuum pump 5 to start, and the other end of the No. 1 air pipe 6 is connected to the inner sampling pipe 114, thereby allowing the sampling gas inside the inner transition pipe 103 to be collected into the inner sampling pipe 114.

[0078] A double-headed handle rod 104 is inserted into the interior of the inner sealing disk 109, wherein the diameter of the top end of the double-headed handle rod 104 is the same as the diameter of the inner sealing disk 109, while the diameter of the bottom end is slightly smaller; it is connected to the column sleeve 108 through the vertical rod 88, and the other end of the column sleeve 108 is connected to the bottom column 107. Therefore, as the vertical rod 88 moves downward, the double-headed handle rod 104 connected to the top end of the bottom column 107 will eventually move downward. The double-headed handle rod 104 is inserted into the center of the inner sealing disk 109, so the double-headed handle rod 104 will move downward along the center of the inner sealing disk 109, and at this time the interior of the inner transition pipe 103 is still in a sealed state.

[0079] The top end of the double-ended handle rod 104 is slidably adapted to the inner side of the inner transition tube 103, and the bottom end of the double-ended handle rod 104 is fixedly connected to the bottom column 107, and the bottom of the bottom column 107 is fixedly connected to the column sleeve 108, and the end of the column sleeve 108 away from the bottom column 107 is fixedly connected to the vertical rod 88.

[0080] A No. 1 blocking ring 100 is slidably fitted between the outer transition pipe 101 and the inner transition pipe 103. The bottom of the No. 1 blocking ring 100 is fixedly connected to the vertical rod 88, and the top of the No. 1 blocking ring 100 is fixedly connected to a double-headed rod 111, and the top of the double-headed rod 111 is fixedly connected to a No. 2 blocking ring 112. As the air inlet pipe 81 and the embedded rod 86 continue to move downward, the embedded rod 86 will pass through the perforation 93 and squeeze the baffle plate 95 downward. At this time, the baffle plate 95 will deflect downward with the ring support 94 as the fulcrum and stretch the elastic sheet 96. At this time, the baffle plate 95 and the elastic sheet 96 play the role of pulling the high-temperature gas surging from bottom to top inside the rotary kiln 1 to avoid a large flow of the airflow. In addition, the air inlet pipe 81 and the embedded rod 86 continue to move downward. The tube 81 continues to move downward, so that the double-headed rod 111 connected to the top of the No. 1 sealing ring 100 will move downward with the No. 2 sealing ring 112, wherein the thickness of the No. 2 sealing ring 112 is much greater than the thickness of the No. 1 sealing ring 100, and finally the No. 2 sealing ring 112 will seal the bottom space of the outer transition tube 101. At the same time, the downward movement of the double-headed handle rod 104 causes its top to squeeze the inner sealing disk 109 downward, and the squeezed inner sealing disk 109 will move downward with the extension block 105 and stretch the elastic reset rod 106, thereby opening the bottom of the inner transition tube 103 and re-sealing the bottom of the outer transition tube 101.

[0081] The top of the outer transition tube 101 is appropriately embedded with an outer sampling tube 113, and the top of the inner transition tube 103 is appropriately embedded with an inner sampling tube 114. The top end of the outer sampling tube 113 is fixedly connected to the No. 2 gas pipe 7, and the top end of the inner sampling tube 114 is fixedly connected to the No. 1 gas pipe 6. At this time, the inner sampling tube 114 will receive sampling gas with smaller airflow fluctuations and slower flow rate, while the outer sampling tube 113 will receive sampling gas with larger airflow fluctuations and faster flow rate, thereby playing the role of separately sampling, collecting and processing airflows of different time periods and different flow rates.

[0082] An opening plate 115 is inserted into the outer side of the peripheral sampling tube 113. A spring 116 is fixedly connected to the outer side of the opening plate 115. The end of the spring 116 away from the opening plate 115 is fixedly connected to the outer side of the peripheral sampling tube 113. A first magnetic block 117 is fixedly connected to the bottom of the opening plate 115.

[0083] A vertical slot 118 is provided on the outside of the outer transition tube 101. A second magnet 119 is slidably mounted within the slot 118. Friction protrusions are provided within the slot 118 to increase friction with the second magnet 119. Furthermore, a repulsive force is generated between the first magnet 117 and the second magnet 119. The outer sampling tube 113 and the inner sampling tube 114 are plugged into the tops of the outer transition tube 101 and the inner transition tube 103, respectively. Before the outer transition tube 101 is separated, the second magnet 119 needs to be moved downward along the slot 118. At this point, the attractive force between the second magnet 119 and the first magnet 117 is less than the elastic force of the spring 116. Ultimately, the elastic force of the spring 116 causes the opening plate 115 to seal the outer sampling tube 113, preventing the sampled gas from escaping during disassembly.

[0084] When the present invention is in use: the air inlet pipe 81 is driven downward by external power equipment and extends into the interior of the rotary kiln 1, wherein a through hole 82 is opened on the outside of the air inlet pipe 81, so the gas inside the rotary kiln 1 will enter the air inlet pipe 81 through the through hole 82, and the inner side of the air inlet pipe 81 is fixedly connected with a patch 87, and the top of the patch 87 is connected to the vertical rod 88, wherein the top and the outer side of the vertical rod 88 are respectively connected to the No. 1 sealing ring 100 and the column sleeve 108, so as the air inlet pipe 81 moves downward with the patch 87, the No. 1 sealing ring 100 and the column sleeve 108 will eventually move downward together, wherein the No. 1 sealing ring 100 seals the space enclosed by the outer transition pipe 101, the partition 102 and the inner transition pipe 103, but as the No. 1 sealing ring 100 moves downward, the bottom of the space will be exposed, and the sampling gas passing through the through hole 82 will float into the space. In addition, the outer side of the air inlet pipe 81 is slidably adapted to be equipped with a leak-proof sleeve 83, wherein the leak-proof sleeve 83 is fixedly mounted on the adapter ring 92, and the top of the leak-proof sleeve 83 is fixedly connected to a fixing rod 80, and the top of the fixing rod 80 is connected to the fixed end of the telescopic ring 89, and the output end of the telescopic ring 89 is connected to the air inlet pipe 81. In addition, the outer side of the air inlet pipe 81 is fixedly connected to an embedded rod 86, so the embedded rod 86 will move downward therewith and pass through the No. 2 infrared sensor 85. At this time, the No. 2 infrared sensor 85 will receive the downward movement of the embedded rod 86. The second infrared sensor 85 will transmit the signal to the vacuum pump 5 connected to the second air pipe 7, wherein the vacuum pump 5 is provided with a control terminal inside, so the control terminal will judge the signal and control the vacuum pump 5 to perform the vacuum processing, wherein the other end of the second air pipe 7 is connected to the peripheral sampling tube 113, and the other end of the peripheral sampling tube 113 is connected to the peripheral transition tube 101, so through the vacuum pump 5, the mixed sampling gas in the peripheral transition tube 101 is completely sucked into the peripheral sampling tube 113.

[0085] The vertical rod 88 is connected to the column sleeve 108, and the other end of the column sleeve 108 is connected to the bottom column 107. Therefore, as the vertical rod 88 moves downward, the double-headed handle rod 104 connected to the top of the bottom column 107 will eventually move downward. The double-headed handle rod 104 is inserted into the center of the inner sealing disk 109, so the double-headed handle rod 104 will move downward along the center of the inner sealing disk 109, and at this time the interior of the inner transition pipe 103 is still in a sealed state.

[0086] As the air inlet pipe 81 and the embedded rod 86 continue to move downward, the embedded rod 86 will pass through the perforation 93 and squeeze the baffle 95 downward. At this time, the baffle 95 will deflect downward with the ring support 94 as the fulcrum and stretch the elastic sheet 96. In addition, the air inlet pipe 81 continues to move downward, so that the double-headed rod 111 connected to the top of the No. 1 sealing ring 100 will move downward with the No. 2 sealing ring 112, wherein the thickness of the No. 2 sealing ring 112 is much greater than the thickness of the No. 1 sealing ring 100, and finally the No. 2 sealing ring 112 will seal the bottom space of the outer transition pipe 101. At the same time, the downward movement of the double-headed handle rod 104 causes its top to squeeze the inner sealing disk 109 downward, and the squeezed inner sealing disk 109 will move downward with the extension block 105 and stretch the elastic reset rod 106. As the space at the bottom of the inner transition tube 103 opens, the slower-flowing sample gas enters the inner transition tube 103. As the embedded rod 86 continues to move downward, it is detected by the first infrared sensor 84. This infrared sensor 84 then transmits the signal to the air pump 5 connected to the first air pipe 6. The control terminal within the air pump 5 then interprets the signal and activates the air pump 5. The other end of the first air pipe 6 is connected to the inner sampling tube 114. When the air inlet pipe 81 is reset, the entire system returns to its original state. Simultaneously, the embedded rod 86 reverses direction, passing the first and second infrared sensors 84, 85, causing both air pumps 5 to cease extraction.
