[0002] A reaction vessel is a device used to realize a reaction process, mainly for multiphase reactions such as liquid-phase, liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid reactions. It is widely used in industries such as chemical and pharmaceutical manufacturing for chemical reactions, mixing, heating, and cooling. In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process.

[0003] In order to precisely control the amount of material added to the reactor, a piston-type feeding device is currently used for feeding.

[0004] However, piston-type feeding devices have some problems during use. The piston's sealing ring is prone to wear due to material friction or high-temperature environments, reducing the piston's sealing performance and causing increased residue inside the piston cavity. This leads to feeding errors and increases the difficulty of cleaning. In such cases, residual material may cause cross-contamination or uncontrolled chemical reactions, requiring frequent disassembly and cleaning, increasing downtime.

[0005] To address this issue, a quantitative feeding device for an isolated reactor is proposed. Summary of the Invention

[0006] To overcome the above deficiencies, this utility model provides an isolated reaction vessel quantitative feeding device. By setting a partition inside the quantitative tank, the quantitative tank is divided into multiple independent feeding zones, which facilitates the separation of materials and avoids cross-contamination between materials. Each feeding zone is equipped with a scraping device, which transfers residual materials to the discharge port to reduce material residue.

[0008] The feeding assembly includes a metering bucket, with a partition fixedly connected inside the metering bucket, dividing the metering bucket into multiple independent feeding zones. Each feeding zone is equipped with a scraper. The metering bucket has a discharge port inside. A support plate is fixedly connected to the outer wall of the metering bucket, and a motor is fixedly connected to the top of the support plate. The motor is connected to the scraper through a transmission device and drives the scraper to move.

[0009] Preferably, the output shaft of the motor is fixedly connected to a gear, the outer wall of the gear is meshed with a gear ring, the outer wall of the gear ring is fixedly connected to a ring, and the bottom of the ring is fixedly connected to a scraper.

[0010] Preferably, the bottom of the ring is placed on top of the partition, and the outer wall of the scraper is rotatably connected to the inside of the metering container.

[0011] Preferably, a discharge device is fixedly connected to the bottom of the metering container, and an electric butterfly valve is installed inside the discharge device.

[0012] Preferably, the disassembly assembly includes a sleeve with a fixed post slidably connected inside the sleeve, and a feed pipe threadedly connected to the top of the can lid.

[0013] Preferably, the bottom of the sleeve is fixedly connected to the top of the can lid.

[0014] Preferably, the top of the fixed column is fixedly connected to the bottom of the metering container.

[0015] Preferably, the bottom of the discharge device is placed at the top of the feed pipe.

[0016] This utility model has the following beneficial effects:

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Reference Figures 1-3 The present invention provides an embodiment of a quantitative feeding device for an isolated reactor, comprising a reactor body 1, a lid 2 detachably connected to the top of the reactor body 1, a disassembly assembly 8 movably mounted on the top of the lid 2, several support feet 3 fixedly connected to the bottom of the reactor body 1, an operation panel 5 for quantitative feeding control fixedly connected to the outer wall of the reactor body 1, a display screen 6 fixedly connected to the outer wall of the operation panel 5, operation buttons 7 fixedly connected to the outer wall of the operation panel 5, and a feeding assembly 4 for adding materials into the reactor body on the top of the lid 2.

[0028] The feeding assembly 4 includes a metering tank 41. A partition 43 is fixedly connected inside the metering tank 41, dividing the material into different independent feeding zones, allowing for the simultaneous addition of different materials. A recessed discharge port 42 is located inside the metering tank 41, positioned at the edge of the feeding zone. A support plate 48 is fixedly connected to the outer wall of the metering tank 41. A motor 44, which drives a scraper 49 to rotate, is fixedly connected to the top of the support plate 48. A gear 45 is fixedly connected to the output shaft of the motor 44. A gear ring 46 meshes with the outer wall of the gear 45. A ring 47 is fixedly connected to the outer wall of the gear ring 46. A scraper 49, extending into the feeding zone, is fixedly connected to the bottom of the ring 47, scraping the material from the feeding zone to the discharge port 42. The scraper 49 is square in shape, with a beveled bottom contacting the material. The bottom of the ring 47 rests on top of the partition 43. There are several partitions 43, arranged around the center of the metering tank 41. The scraper 49 is arranged in a square shape, with its outer wall attached to the inside of the metering tank 41. The bottom of the metering tank 41 is fixedly connected to a discharge device 410. The discharge device 410 has a square top and a round bottom, with the square top having a round interior. The discharge device 410 is equipped with an electric butterfly valve 411 driven by an electric actuator. After different materials are placed into different partitions 43 through the opening at the top of the metering tank 41, the electric butterfly valve 411 inside the discharge device 410 is opened on the control panel 5, allowing the material to enter the feed pipe 83 at the top of the tank cover 2 through the discharge port 42 inside the metering tank 41. The motor 44 is then turned on, causing the motor 44 to drive the gear 45 to rotate, which in turn drives the gear ring 46 to rotate, causing the ring 47 fixed to the gear ring 46 to rotate. At the same time, the scraper 49 fixed to the bottom of the ring 47 moves inside the metering tank 41, pushing the remaining material into the discharge port 42 and then into the reactor tank 1 through the feed pipe 83 via the discharge device 410.

[0029] Reference Figures 2-4 The disassembly assembly 8 includes a sleeve 81, with a fixing post 82 slidably connected inside the sleeve 81. The top of the can lid 2 is threadedly connected to a feed pipe 83, which is located on the top of the can lid 2 and distributed in a ring around the center of the can lid 2. The bottom of the sleeve 81 is fixedly connected to the top of the can lid 2. A groove is opened inside the sleeve 81, and the outer wall of the fixing post 82 is slidably connected inside the groove. The top of the fixing post 82 is fixedly connected to the bottom of the metering bucket 41. The bottom of the discharge device 410 is placed on the top of the feed pipe 83. The fixing post 82 is set at the bottom of the metering bucket 41, and then the fixing post 82 is inserted into the inside of the sleeve 81, so that the metering bucket 41 is fixed on the top of the can lid 2. When disassembly and cleaning are required, the fixing post 82 under the metering bucket 41 is taken out from the inside of the sleeve 81, and the feed pipe 83 is rotated to disconnect it from the can lid 2.

[0030] Working principle: In use, different materials are put into different feeding areas through the opening at the top of the metering tank 41. Then, the electric butterfly valve 411 inside the discharge device 410 is opened on the control panel 5, so that the material enters the feed pipe 83 at the top of the tank cover 2 through the discharge port 42 inside the metering tank 41. The motor 44 is turned on, so that the motor 44 drives the gear 45 to rotate, which drives the gear ring 46 to rotate, so that the ring 47 fixed to the gear ring 46 rotates. At the same time, the scraper 49 fixed at the bottom of the ring 47 moves inside the metering tank 41, pushing the material into the discharge port 42. Then, the material enters the reactor tank 1 through the feed pipe 83 from the discharge device 410. The bottom of the metering tank 41 is fixed with a fixing post 82, and the fixing post 82 is inserted into the inside of the sleeve 81 to fix the metering tank 41 to the top of the tank cover 2. When it is time to disassemble and clean, the fixing post 82 under the metering tank 41 is taken out from the inside of the sleeve 81, and the feed pipe 83 is rotated to disconnect it from the tank cover 2.
