[0002] Chemical drugs refer to compounds that are synthesized chemically or extracted from natural substances and are used to treat diseases, relieve symptoms or improve health. They achieve their therapeutic effects by intervening in the physiological and metabolic processes of organisms, and the safety isolation devices for chemical drug production are a series of equipment and measures designed to ensure safety and controllability during the drug synthesis process. These devices are designed to prevent the leakage of hazardous substances, reduce the risk of operators coming into contact with toxic or harmful chemicals, and protect the environment from pollution.

[0003] A Chinese patent document with a search announcement number of CN215233725U discloses a mixing device for chemical drug production, including a bottom plate, a fixed frame, a mixing barrel and a scraper rod. When the mixing device for chemical drug production is used, multiple chemical raw materials are poured into the mixing barrel, and the first motor and the second motor are turned on by a PLC controller. The first motor drives the stirring rod to rotate through a coupling, and the stirring rod drives the stirring paddle to rotate to stir the mixed material. At the same time, the stirring rod drives the scraper rod to scrape the material adhered to the inner wall of the mixing barrel. At the same time, the second motor drives the gear to rotate, and the gear and the gear ring are engaged to drive the mixing barrel to rotate slowly. The guide rail on the outer wall of the mixing barrel cooperates with the guide wheels on both sides to realize lateral support for the mixing barrel. During the rotation of the mixing barrel, the base provides vertical stable support for it. Through the cooperation of the mixing barrel and the stirring paddle, the material mixing efficiency and effect are improved. The mixed material is discharged from the discharge pipe and is completely mixed.

[0004] The mixing device for chemical drug production will produce by adding chemicals into a hopper during production, but the feed port cannot be sealed and isolated during production, resulting in the leakage of harmful substances into the surrounding environment, causing pollution and damage to the surrounding environment.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 and Figure 5 The utility model provides an embodiment: a safety isolation device for chemical drug production, comprising a production tank 1, a stirring assembly 25 is arranged at the bottom of the production tank 1, a feed port 3 is fixedly connected to the left side of the upper part of the production tank 1, a mounting plate 4 is fixedly connected to the outside of the feed port 3, mounting frames 5 are fixedly connected to the outside of the mounting plate 4 on both sides, two mounting frames 5 are rotatably connected to a rotating rod 7 inside, a turntable 6 is fixedly connected to the front side of the outside of the rotating rod 7, a gear 8 is fixedly connected to the middle of the rotating rod 7, a rack plate 9 is meshed and connected to the lower part of the gear 8, a moving frame 10 is fixedly connected to the lower part of the rack plate 9, rollers 11 are rotatably connected to the outer sides of the moving frame 10, one end of a connecting rod 13 is rotatably connected to the inside of the moving frame 10, an isolation cover 14 is arranged on the upper part of the mounting plate 4, and the other ends of multiple connecting rods 13 are rotatably connected to the upper periphery of the isolation cover 14, and slide grooves 12 are opened on both sides of the inside of the mounting plate 4, and multiple rollers 11 are slidably connected to the inside of the two slide grooves 12.

[0028] First, when it is necessary to pour chemicals into the production tank 1 through the feed port 3, the operator first needs to ensure that the feed port 3 is completely isolated from the external environment. At this time, by rotating the turntable 6, the turntable 6 rotates with the rotating rod 7, and a gear 8 is fixedly connected to the outside of the rotating rod 7. When the rotating rod 7 rotates, the gear 8 also rotates. The rotation of the gear 8 does not exist in isolation, and it acts through the rack plate 9 meshing with the lower part. When the gear 8 rotates, the rack plate 9 moves along the preset path under the drive of the gear 8. A mobile frame 10 is fixedly connected to the lower part of the rack plate 9, and this mobile frame 10 starts to move under the drive of the rack plate 9. The design of the mobile frame 10 is very clever. It moves horizontally inside the two slide grooves 12 through four rollers 11. This design not only ensures the stable movement of the mobile frame 10, but also greatly reduces the friction resistance, making the entire isolation process smoother. As the mobile frame 10 moves, it moves with the four connecting rods 13 that are connected to the inner periphery. The other ends of the four connecting rods 13 are rotatably connected to an isolation cover 14. When the mobile frame 10 moves to the designated position, the four connecting rods 13 drive the isolation cover 14 to move to the top of the feed port 3. Since the four connecting rods 13 are rotatably connected to the isolation cover 14, when the isolation cover 14 moves to the top of the feed port 3, it can be easily inserted into the inside of the feed port 3 to form a tight seal. In this way, the feed port 3 is effectively isolated, thereby avoiding the situation where the drug overflows from the inside of the production tank 1 during the production of chemical drugs. This isolation method is not only easy to operate, but also has a good sealing effect, providing a strong guarantee for the production of chemical drugs. It not only effectively prevents the spillage of drugs, but also reduces the negative impact on the environment.

[0029] Reference Figure 4 and Figure 6 A fan 15 is fixedly connected to the left upper part of the production tank 1, and one end of an air inlet pipe 16 is fixedly connected to the input end of the fan 15, and the other end of the air inlet pipe 16 is fixedly connected to the inside of the production tank 1, and one end of a delivery pipe 17 is fixedly connected to the output end of the fan 15. A filter box 18 is arranged on the left outer side of the production tank 1, and the other end of the delivery pipe 17 is fixedly connected to the inside of the filter box 18. A filter screen 19 is installed inside the filter box 18, and a HEPA layer plate 20 is arranged at the lower part of the filter screen 19. An activated carbon adsorption plate 21 is arranged at the lower part of the HEPA layer plate 20, and an exhaust port 22 is fixedly connected to the left outer side of the filter box 18.

[0030] First, when the fan 15 is started, the air inlet pipe 16 will quickly suck in the harmful gases generated during the production process. These gases are then transported to the interior of the filter box 18, where the harmful gases are first processed by the filter 19. The main function of the filter 19 is to capture larger particles and some harmful chemicals. Once these particles and chemicals come into contact with the filter 19, they will be firmly adsorbed on it, thereby effectively preventing them from continuing to spread. After the initial filtration of the filter 19, the gas further flows to the HEPA layer 20. The HEPA layer 20 is a device specially designed to capture tiny particles. It can effectively filter out various tiny particles including bacteria, viruses and other tiny harmful substances. This stage of filtration is crucial to ensure the purity of the gas because it can remove many potential sources of pollution. Finally, the gas will flow through the activated carbon adsorption plate 21. Activated carbon is a substance with a porous structure and therefore has a very strong adsorption capacity. It can adsorb organic compounds and some gaseous pollutants, thereby effectively removing harmful chemicals, odors and harmful volatile organic compounds in the remaining gas. This step is crucial to improving the quality of the gas, because it can ensure that the final discharged gas meets environmental protection standards. After this series of treatment processes, the final filtered gas is discharged through the exhaust port 22. Such a design is not only convenient for filtering and purifying the harmful gases generated during the production of chemical drugs, but also can effectively prevent the harmful gases from polluting the production area, thereby protecting the products in the production process from pollution. This is of great significance for ensuring the purity and efficacy of drugs, and also meets the environmental protection requirements of modern industrial production.

[0031] Reference Figure 1 and Figure 2 The stirring assembly 25 includes a motor 2501, which is arranged at the lower part of the production tank 1. The output end of the motor 2501 is fixedly connected to a transmission rod 2502, and stirring rods 2503 are fixedly connected to the outside of the transmission rod 2502 on all sides.

[0032] During production, by starting the motor 2501, the motor 2501 drives the transmission rod 2502 fixedly connected to the output end to rotate, and the transmission rod 2502 drives the stirring rod 2503 fixedly connected to the outside to rotate, so that the chemicals inside the production tank 1 are fully mixed and the reaction rate is accelerated.

[0033] Reference Figure 1 , Figure 2 and Figure 3A support plate 23 is fixedly connected to the left side of the outside of the production tank 1, the filter box 18 is fixedly connected to the upper part of the support plate 23, an L-shaped plate 24 is fixedly connected to the lower part of the production tank 1, the motor 2501 is fixedly connected to the upper part of the L-shaped plate 24, a transparent window 27 is installed on the front side of the inside of the production tank 1, a bracket 2 is fixedly connected to the outside of the production tank 1, a discharge port 26 is fixedly connected to the right side of the lower part of the production tank 1, and a valve is arranged outside the discharge port 26.

[0034] The support plate 23 is provided to facilitate fixing the filter box 18, the L-shaped plate 24 is provided to facilitate fixing the motor 2501, the transparent window 27 is provided to facilitate direct viewing of the internal conditions of the production tank 1, the bracket 2 is provided to facilitate fixing the production tank 1, the discharge port 26 is provided to facilitate discharge of the produced chemical drugs, and the rear valve can prevent drug leakage.

[0035] Working principle: When the chemical drugs are poured into the production tank 1 through the feed port 3 for production, when the feed port 3 needs to be isolated from the outside, the turntable 6 is rotated, and the gear 8 fixedly connected to the outside of the turntable 6 rotates, and the gear 8 rotates and moves the rack plate 9 meshing at the bottom, and the rack plate 9 moves and moves the mobile frame 10 fixedly connected at the bottom, and the mobile frame 10 moves horizontally inside the two slide grooves 12 through four rollers 11, and when the mobile frame 10 moves, it moves with the connecting rods 13 connected to the inside and rotating around, and the four connecting rods 13 move and move the isolation cover 14 connected to the other end, and when the isolation cover 14 moves to the top of the feed port 3, since the four connecting rods 13 and the isolation cover 14 are connected in rotation, Therefore, when the isolation cover 14 moves to the top of the feed port 3, the isolation cover 14 will be stuck in the feed port 3, so that the feed port 3 can be sealed and isolated to prevent the drug from overflowing from the inside of the production tank 1 during the production of chemical drugs, thereby reducing the negative impact on the environment. Then, during the production of chemical drugs, the fan 15 is started to inhale the harmful gas generated during the production of chemical drugs through the air inlet pipe 16, and then transported to the inside of the filter box 18 through the delivery pipe 17. First, the harmful gas will pass through the filter screen 19 after entering the filter box 18. This stage is mainly used to capture larger particles and some harmful chemicals. After being filtered by the preliminary filter screen 19, the gas will further flow to the HEPA layer plate 20. The HEPA layer plate 20 is specially designed to capture tiny particles, including bacteria, viruses and other tiny harmful substances. Finally, the gas will flow through the activated carbon adsorption plate 21. Due to its porous structure, activated carbon has a very strong adsorption capacity and is particularly suitable for adsorbing organic compounds and some gaseous pollutants. The activated carbon layer can effectively remove harmful chemicals, odors and harmful volatile organic compounds in the remaining gas. Finally, the filtered gas can be discharged through the exhaust port 22, which makes it easy to filter and purify the harmful gases generated during the production of chemical drugs, prevent harmful gases from polluting the production area, thereby protecting the products in the production process from contamination and ensuring the purity and efficacy of the drugs.
