[0002] Benzothiophene derivatives refer to organic compounds with benzene ring and thiophene ring structures, which are compounds obtained by chemical reaction of benzothiophene. Such derivatives are widely used in industry, agriculture, medicine, etc. For example, they are used as herbicides, pesticides, plant growth promoters, dyes, organic semiconductors, etc. At the same time, many drug molecular skeletons also contain benzothiophene structures, such as Qilutong and raloxifene. Harmful gases will be produced in the synthesis process of benzothiophene derivatives, so the harmful gases need to be filtered.

[0024] The arrangement filters the harmful gases generated during the synthesis of benzothiophene derivatives in sequence through the first filter plate 12, the second filter plate 13 and the third filter plate 14 to remove solid impurities in the harmful gases. Secondly, two groups of honeycomb activated carbons 15 are used to adsorb harmful components in the harmful gases generated during the synthesis of benzothiophene derivatives to prevent the harmful gases from being directly discharged into the air, thereby protecting the environment.

[0025] The side wall of the body 1 is provided with a plurality of first mounting grooves 101, and the side wall of the cover plate 2 is provided with a plurality of slots 21, which correspond to the first mounting grooves 101. A fixing assembly 3 is provided inside the body 1, and the fixing assembly 3 is located in the first mounting groove 101. The fixing assembly 3 includes a limiting column 31, and the side wall of the limiting column 31 is fixedly connected to the limiting plate 32.

The end of the rotating block 35 away from the limiting plate 32 is fixedly connected to a pulling block 36. When the cover plate 2 is installed, the cover plate 2 is directly placed in the second mounting groove 10 2, and then press the cover plate 2 vertically downward, so that the cover plate 2 squeezes the limiting column 31, so that the limiting column 31 squeezes the spring 34 through the limiting plate 32, and when the first installation groove 101 is level with the card slot 21, the elastic force of the spring 34 is used to push the limiting column 31 away from the end of the rotating block 35 into the card slot 21 through the limiting plate 32, thereby completing the installation of the cover plate 2. Secondly, when the cover plate 2 needs to be disassembled, directly pull the pull block 36 to make the pull block 36 slide out of the first installation groove 101. At this time, the limiting column 31 slides out of the card slot 21, and then rotate the pull block 36 to make the pull block 36 drive the rotating block 35 to rotate in the limiting groove 33, and then use the side wall of the body 1 to clamp the pull block 36 to achieve the limiting of the limiting column 31, and then slide the limiting column 31 out of the card slot 21.

[0026] The cover plate 2 is in a stepped shape, and a rubber frame 22 is fixedly connected to the lower end of the cover plate 2 to seal the connection between the cover plate 2 and the side wall of the second mounting groove 102 to avoid leakage of harmful gases at the connection between the cover plate 2 and the side wall of the second mounting groove 102.

[0028] One end of the limiting column 31 away from the pulling block 36 is provided with an inclined surface for vertically pressing the cover plate 2 downward so that the cover plate 2 squeezes the limiting column 31 and the limiting column 31 slides into the first installation groove 101 .

[0029] The filter holes on the first filter plate 12, the second filter plate 13 and the third filter plate 14 are successively reduced to achieve graded filtration of harmful gases and increase the filtering effect.

[0030] Working principle: First, the harmful gases generated during the synthesis of benzothiophene derivatives are filtered in turn through the first filter plate 12, the second filter plate 13 and the third filter plate 14 to remove solid impurities in the harmful gases. Secondly, two groups of honeycomb activated carbon 15 are used to adsorb harmful components in the harmful gases generated during the synthesis of benzothiophene derivatives to prevent the harmful gases from being directly discharged into the air and protect the environment. When installing the cover plate 2, place the cover plate 2 directly above the second installation groove 102, and then press the cover plate 2 vertically downward. The cover plate 2 squeezes the limit column 31, and the limit column 31 squeezes the spring 34 through the limit plate 32. When the first installation groove 101 and the card groove 21 are aligned, Normally, the elastic force of the spring 34 is used to push the end of the limiting column 31 away from the rotating block 35 through the limiting plate 32 to be stuck in the slot 21, thereby completing the installation of the cover 2. Secondly, when the cover 2 needs to be disassembled, the pull block 36 is directly pulled, and the pull block 36 slides out of the first installation slot 101. At this time, the limiting column 31 slides out of the slot 21, and then the pull block 36 is rotated, and the pull block 36 drives the rotating block 35 to rotate in the limiting slot 33. Then, the side wall of the body 1 is used to clamp the pull block 36 to achieve the limiting of the limiting column 31, and then the limiting column 31 can be slid out of the slot 21, which is convenient for cleaning and replacement of the first filter plate 12, the second filter plate 13, the third filter plate 14 and the honeycomb activated carbon 15.
