Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to waste gas treatment equipment in an artemisinin extraction process. Background Art

[0002] As an important pharmaceutical ingredient, artemisinin generates a large amount of waste gas during its extraction process. These waste gases usually contain solid particles, fibers and other harmful substances. If they are directly discharged into the environment, they will not only pollute the atmosphere, but may also have a negative impact on the surrounding ecosystem and human health. Therefore, it is particularly important to effectively treat the waste gas during the extraction of artemisinin. During the extraction of artemisinin, solid particles or fibers in the raw materials (such as Artemisia annua plants) may be discharged along with the waste gas. These solid impurities may include plant fibers, undissolved solid substances, etc. After long-term use, the filter will accumulate a large amount of dust, particulate matter, organic solvent residues and other impurities, which will block the pores of the filter and reduce its air permeability and filtration efficiency.

[0003] However, traditional waste gas treatment methods mostly use a single filter device to capture pollutants in the waste gas through filter materials. However, this method has many shortcomings. First, the filter material is prone to clogging after long-term use, resulting in reduced filtration efficiency, requiring frequent replacement or cleaning, and increasing operating costs. Second, a single filter device cannot achieve continuous filtration. When the filter material needs to be cleaned or replaced, the equipment must be shut down, affecting production efficiency.

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] Please refer to Figure 1-Figure 6 As shown, a waste gas treatment device in the process of artemisinin extraction includes two groups of exhaust pipes 1, a first mounting frame 101 is installed at one end of the left exhaust pipe 1, and a second mounting frame 102 is installed at one end of the right exhaust pipe 1 close to the first mounting frame 101, and a filtering mechanism 2 is installed at the upper ends of the first mounting frame 101 and the second mounting frame 102, and the filtering mechanism 2 includes two groups of filter plates 204 and a fixing rod 203, the two groups of filter plates 204 are fixedly connected by the fixing rod 203, and the two groups of filter plates 204 are movably connected between the first mounting frame 101 and the second mounting frame 102, and a lifting mechanism 3 is installed at the upper end of the first mounting frame 101, and the lifting mechanism 3 includes a fixing frame 301, and a cleaning mechanism 4 is installed on the outer side of the fixing frame 301, and the cleaning mechanism 4 includes two groups of guide rails 401, a cleaning frame 406 and a connecting plate 404, the two groups of guide rails 401 are fixedly connected by the connecting plate 404, and the cleaning frame 406 is slidably connected to the inside of the guide rail 401.

[0029] In this solution, the left exhaust pipe 1 is connected to the external artemisinin extraction device, and the exhaust gas then enters the filtering mechanism 2. When the exhaust gas passes through the filter plate 204, the solid particles or fibers therein are captured by the filter plate 204, thereby achieving the purification of the exhaust gas. The two sets of filter plates 204 can be rotated;

[0030] Furthermore, the lifting mechanism 3 can drive the cleaning mechanism 4 to move up and down, and the cleaning mechanism 4 can clean both sides of the filter plate 204. When one group of filter plates 204 needs to be cleaned, the filter plates 204 move to the top of the first installation frame 101, and the other group of filter plates 204 move to between the first installation frame 101 and the second installation frame 102 to continue the filtering operation, thereby rotating the filtering operation and the cleaning operation to maintain the high-efficiency filtering capacity of the filter plates 204.

[0031] Please refer to Figure 2-Figure 3As shown, the filtering mechanism 2 also includes two groups of fixing seats 201, which are respectively fixedly connected to the upper ends of the first installation frame 101 and the second installation frame 102, and a rotating shaft 202 is rotatably connected between the two groups of fixing seats 201, and a fixing rod 203 is fixedly connected to the outer side of the rotating shaft 202.

[0032] The filtering mechanism 2 also includes a first driving motor 206, which is fixedly mounted on the upper end of the second mounting frame 102. The output end of the first driving motor 206 is fixedly connected to a driving gear 207. One end of the rotating shaft 202 extends to the outside of one group of fixed seats 201 and is fixedly connected to a driven gear 205. The driven gear 205 is meshed with the driving gear 207.

[0033] Furthermore, the first driving motor 206 can drive the driving gear 207 to rotate, thereby driving the rotating shaft 202 to rotate through the driven gear 205, and then driving the fixing rod 203 to rotate the two groups of filter plates 204 in rotation, so that when one group of filter plates 204 is being cleaned, the other group of filter plates 204 is still performing filtering operations, thereby reducing downtime and improving filtering efficiency;

[0034] Furthermore, sealing gaskets are provided between the filter plate 204 and the first mounting frame 101 and the second mounting frame 102 to prevent exhaust gas from leaking out.

[0035] Please refer to Figure 4 As shown, the interior of the fixed frame 301 is fixedly connected with a guide rod 302, the outer side of the guide rod 302 is slidably connected with a guide block 303, the guide block 303 is fixedly connected to one set of guide rails 401, the interior of the fixed frame 301 is rotatably connected with a lifting screw 305, the upper end of the fixed frame 301 is fixedly installed with a servo motor 304, the output end of the servo motor 304 is fixedly connected to the lifting screw 305, the outer side of the lifting screw 305 is threadedly connected with a lifting block 306, and one end of the lifting block 306 is fixedly connected to one set of guide rails 401.

[0036] Furthermore, the servo motor 304 is electrically connected to an external power source, and the servo motor 304 can drive the lifting screw 305 to rotate, and then drive the cleaning mechanism 4 to move up and down through the lifting block 306 to clean both sides of the filter plate 204. When the filter plate 204 rotates, the cleaning mechanism 4 is located at the top inner side of the fixing frame 301 to prevent the cleaning mechanism 4 from blocking the filter plate 204.

[0037] Furthermore, the guide rod 302 and the guide block 303 can guide the movement of the cleaning mechanism 4, so that it can move stably.

[0038] Please refer to Figure 5-Figure 6As shown, a slider 405 adapted to the guide rail 401 is fixedly connected to the outer side of the cleaning frame 406 , a connecting rod 407 is fixedly connected to one end of the cleaning frame 406 , and a driving rod 411 is fixedly connected to one end of the cleaning frame 406 via the connecting rod 407 .

[0039] The upper end of the guide rail 401 is fixedly connected to a mounting plate 403, and a second drive motor 408 is fixedly installed on one side of the mounting plate 403. The output end of the second drive motor 408 extends to the outer side of the mounting plate 403 and is rotatably connected to a drive roller 409. A track groove 410 is opened on the outer side of the drive roller 409. The track grooves 410 are connected from beginning to end, and a drive rod 411 is slidably connected to the inside of the track groove 410.

[0040] The lower end of the guide rail 401 is fixedly connected with an electric heating plate 402 .

[0041] Furthermore, the second driving motor 408 can drive the driving roller 409 connected thereto to rotate synchronously. Since the outer side of the driving roller 409 is provided with a track groove 410 that is connected end to end, the driving rod 411 can slide inside the track groove 410. One end of the driving rod 411 is fixedly connected to the connecting rod 407, and the connecting rod 407 is connected to one end of the cleaning frame 406. Therefore, when the driving roller 409 rotates, the shape of the track groove 410 guides the driving rod 411 to move along a predetermined path, and then drives the cleaning frame 406 to move along the guide rail 401 through the connecting rod 407, so that the cleaning frame 406 can move back and forth along the predetermined track to perform the cleaning task. The electric heating plate 402 can heat both sides of the filter plate 204 to facilitate the removal of stubborn pollutants.

[0042] An exhaust fan 103 is installed inside the right exhaust pipe 1, and exhaust gas can be extracted through the exhaust fan 103.

[0043] The working principle and use process of the present invention are as follows: first, the waste gas generated by the artemisinin extraction device is introduced into the waste gas treatment equipment through the left exhaust pipe 1. At the same time, the exhaust fan 103 inside the right exhaust pipe 1 is started to extract the waste gas to ensure that the waste gas enters the treatment process smoothly. The waste gas enters the filtering mechanism 2 and first passes through the filter plate 204. The filter plate 204 captures solid particles or fibers in the waste gas to achieve waste gas purification. When the filter plate 204 needs to be cleaned, the first drive motor 206 is started to drive the active gear 207 to rotate, thereby driving the rotating shaft 202 and the fixed rod 203 to rotate, so that the two groups of filter plates 204 are rotated. When one group of filter plates 204 is being cleaned, the other group of filter plates 204 continues to perform the filtering operation to ensure continuous operation of the equipment and reduce downtime. At the same time, the lifting mechanism 3 starts to work, the servo motor 304 drives the lifting screw 305 to rotate, and drives the cleaning mechanism 4 to move up and down through the lifting block 306, and the cleaning mechanism 4 moves to the top of the filter plate 204 that needs to be cleaned. At this time, the second driving motor 408 is started to drive the driving roller 409 to rotate, and the track groove 410 on the outer side of the driving roller 409 guides the driving rod 411 to move along the predetermined path, and then drives the cleaning frame 406 to move along the guide rail 401 through the connecting rod 407, and the two sides of the filter plate 204 are cleaned by the reciprocating motion of the cleaning frame 406. The electric heating plate 402 can heat the two sides of the filter plate 204 to facilitate the removal of stubborn pollutants. After cleaning is completed, the lifting mechanism 3 is started again to move the cleaning mechanism 4 to the top of the inner side of the fixing frame 301 to prevent the filter plate 204 from being blocked.
