Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a biopharmaceutical reaction vessel. Background Technology

[0002] Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries as pressure vessels to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposers, and polymerization kettles. Materials typically include carbon manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel), and other composite materials. In a broad sense, a reactor is a stainless steel container where physical or chemical reactions occur. The structural design and parameter configuration of the container are tailored to different process requirements. Design conditions, processes, inspection, manufacturing, and acceptance must adhere to relevant technical standards to achieve the heating, evaporation, cooling, and low-to-high-speed mixing reaction functions required by the process.

[0003] However, current biopharmaceutical reactors often rely on stirring to mix biopharmaceutical raw materials during operation. Since the reactor cannot be shaken, the mixing efficiency is relatively low. To address this issue, a new biopharmaceutical reactor has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a biopharmaceutical reaction vessel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A biopharmaceutical reactor includes a base plate. Vertical plates are symmetrically fixedly mounted on the top of the base plate, and a reactor body is disposed between the vertical plates. A first connecting shaft is fixedly mounted on one side of the reactor body, and a second connecting shaft is symmetrically fixedly mounted on the other side of the reactor body. The first and second connecting shafts are rotatably connected to their respective vertical plates via bearings. The end of the first connecting shaft passes through the corresponding vertical plate, and a turntable is fixedly connected to one end of the first connecting shaft outside the vertical plate. A second motor is disposed below the first connecting shaft and fixedly mounted on the corresponding vertical plate. A wheel is fixedly connected to the output end of the second motor through the vertical plate. A connecting rod is disposed between the wheel and the turntable, and connecting rods are connected at both ends. The connecting rod has connecting pins at both ends, which are connected to the connecting holes on the turntable and the wheel at different eccentric distances. The connecting rod is hinged to the corresponding turntable and wheel by connecting pins at both ends. The top of the vessel is fixedly installed with a vessel cover by bolts. The top of the vessel cover is fixedly installed with a first motor. The bottom of the vessel cover is rotatably connected to a stirring shaft. The top of the stirring shaft passes through the vessel cover and is fixedly connected to the output end of the first motor. The side wall of the stirring shaft is fixedly installed with a first stirring rod, a second stirring rod, and a third stirring rod inside the vessel. The vessel cover has different addition ports. The end of the addition port is fixedly installed with a sealing plate by bolts. The discharge port of the vessel is installed with a discharge valve.

[0007] As a further embodiment of this utility model: a first scraper and a second scraper are provided inside the vessel body, and the first scraper and the second scraper are in contact with the inner wall of the vessel body and the inner wall of the vessel lid.

[0008] As a further improvement of this utility model, the top of the first scraper is higher than the bottom of the second scraper.

[0009] As a further embodiment of this utility model: the vessel body includes an outer vessel body and an inner vessel body, the top and bottom of the inner vessel body are fixedly connected to the outer vessel body by bolts, and the discharge valve is fixedly installed at the discharge port at the bottom of the inner vessel body.

[0012] As a further improvement of this utility model, lifting rings are symmetrically fixedly installed on the top of the kettle lid.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In use, the biopharmaceutical raw materials are added into the inner body of the vessel through different addition ports on the lid. After the sealing plate is closed, the first motor and the second motor operate. The first motor drives the stirring shaft to rotate. The stirring shaft stirs the raw materials through the first stirring rod, the second stirring rod, and the third stirring rod fixedly connected to the side wall. At the same time, the output end of the second motor drives the rotating wheel to rotate. The rotating wheel drives the turntable to swing back and forth through the connecting pin and the connecting rod. The swinging turntable drives the vessel body to swing back and forth through the first connecting shaft, thereby making the biopharmaceutical raw materials in the vessel fully mixed and making the raw material reaction more uniform and complete.

[0015] 2. In this utility model, the connecting rod is connected to the connecting holes of the rotating wheel with different eccentricities through the connecting pin, so as to adjust the swing amplitude of the vessel body.

[0016] 3. In this invention, the heat exchange medium is delivered to the heat exchange coil through the feed inlet. The heat exchange coil increases the heat exchange area and exchanges heat with the inner cavity of the outer vessel, thereby achieving heat exchange with the inner vessel. This is beneficial for providing constant temperature during pharmaceutical reactions and ensuring the efficiency of biopharmaceutical production.

[0017] 4. When the stirring shaft rotates, the rotating stirring shaft, through the first stirring rod, the second stirring rod, and the third stirring rod, drives the first scraper and the second scraper to rotate, cleaning the inner wall of the inner vessel body and the inner wall of the vessel lid, thus preventing the raw materials from sticking to the inner wall of the inner vessel body and the inner wall of the vessel lid.
