Description
Technical Field
[0001] This utility model relates to an aeration pipe connection device for a reaction vessel used in the preparation of ferric chloride, and belongs to the field of ferric chloride production technology. Background Technology
[0002] In the production of ferric chloride, the reactor is a crucial piece of equipment for ensuring complete reaction of raw materials and uniform gas-liquid mixing. To guarantee that gas can effectively enter the reactor and be evenly distributed during the reaction, it is usually necessary to transport and stir the reaction system through aeration pipes. Achieving a robust, sealed, and efficient connection between the reactor and the aeration pipes directly affects the mixing effect, temperature control, and the quality and production efficiency of the final product.
[0003] Currently, most manufacturing equipment uses a fixed bracket, connecting pipes, and sealing devices to form an aeration pipe connection system, connecting the aeration pipes to the air inlet of the reactor or the interface of the aeration device. This system generally fixes the connecting components with metal clamps, clips, or bolts, and sets sealing rings or gaskets at the interfaces.
[0004] Traditional fixing and sealing methods are prone to aging and loosening in high-temperature and highly corrosive reaction environments, failing to maintain stable airtightness over the long term. The simple structure of the connection device often results in uneven gas distribution, leading to poor mixing within the reactor and thus affecting the efficiency and quality of ferric chloride production. Furthermore, existing equipment experiences significant vibration during operation, seals are easily damaged, and maintenance costs are high. To address these issues, there is an urgent need for an improved reactor aeration pipe connection device to achieve a more robust, reliable, sealed, and uniform gas delivery effect.

[0027] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0028] Example 1
[0029] like Figures 1-5 As shown, an aeration pipe connection device for a reactor used in the preparation of ferric chloride includes a sealing device 2, a connecting device 1, and a fixing device 3. The sealing device 2 is disposed on both sides of the connecting device 1, the fixing device 3 can fix the connecting device 1, and the connecting device 1 can connect the reactor and the aeration pipe.
[0030] Reference Figure 1 The connecting device 1 consists of a connecting pipe 11 and a connecting bracket 12, used to achieve a gas passage and a stable connection between the reactor and the aeration pipe. The sealing device 2 is located at both ends of the connecting pipe 11 to ensure a seal at the connection point, preventing gas leakage or external impurities from entering the reactor. The fixing device 3 is used to securely fix the connecting device 1, preventing loosening of the connection due to vibration or temperature changes, and ensuring stable overall operation.
[0031] The connecting pipe 11 is a hollow cylindrical pipe made of corrosion-resistant metal alloy. Connecting flanges 111 are provided at both ends of the connecting pipe 11. The connecting flanges 111 can be connected to the air inlet of the reactor or the flange of the aeration pipe and are firmly connected by bolts.
[0032] A flow divider hole 112 is provided inside the connecting pipe 11. Multiple flow divider holes 112 are arranged in a spiral pattern along the axial direction on the inner side of the connecting pipe 11. The flow divider holes 112 can be used to uniformly disperse the input gas flow and guide the gas to enter the reactor more evenly. The shape of the flow divider hole 112 is circular.
[0033] The diversion hole 112 can establish a gas delivery channel to ensure the aeration requirements in the reactor. The diversion hole 112 can be used to pre-distribute the gas and improve the mixing and mass transfer efficiency in the reactor. The connection flanges 111 at both ends and the sealing device 2 are used to ensure good sealing of the gas delivery process.
[0034] The connecting bracket 12 is U-shaped, and an extension bracket is provided at the bottom of the connecting bracket 12. The connecting bracket 12 has a U-shaped or frame structure and is made of high-temperature resistant and corrosion-resistant materials to ensure stable operation over a long period of time. A flange 112 is provided on the side of the connecting bracket 12, which extends to both sides and has a certain gap in the middle. The flange 112 can be fitted with the structure of the fixing device 3. Bolts 121 are provided on the side of the connecting bracket 112, which can fix the connecting bracket 12 to the side of the reactor or to the pre-drilled mounting holes on the reactor.
[0035] The connecting bracket 12 provides stable support for the connecting pipe 11, ensuring that the connecting pipe 11 can maintain the predetermined position and angle. It also facilitates the connection between the gas inlet and aeration pipe of the reactor. The connecting bracket 12 and the fixing device 3 are fitted with a flange to tighten and reinforce the outside of the connecting pipe.
[0036] The sealing device 2 mainly consists of a sealing gasket, which ensures good airtightness between the two ends of the connecting pipe 11 and the reactor or aeration pipe. In this embodiment, the sealing device 2 is typically annular, matching the size of the connecting flange 111, and can be embedded between the flange interfaces. The sealing gasket is made of polytetrafluoroethylene (PTFE) and is installed between the connecting flange 111 and the reactor inlet or aeration pipe flange. It is tightened with bolts to form a high-pressure contact surface, achieving a good sealing effect.
[0037] The sealing device 2 can prevent gas or liquid from leaking out during the reaction process, maintain the pressure and gas stability inside the reactor, prevent external air or impurities from entering the reactor, and maintain the purity and safety of the process.
[0038] The fixing device 3 is used to further fix and reinforce the connecting device 1, reducing loosening or displacement caused by vibration, thermal expansion and contraction, etc. The specific structure is as follows:
[0039] A flange 31 is provided on the bottom side of the fixing device 3. This flange 31 is a single protrusion that can cooperate with the flange 112 on the connecting bracket 12 and can be fixed by bolts. This ensures the stability of the connecting pipe 11 during operation.
[0040] In this embodiment, the fixing device 3 is semi-circular, and the fixing devices 3 are connected together by the connecting shaft 32 to ensure that the fixing device 3 can be installed on the surface of the connecting pipe 11.
[0041] The connecting shaft 31 is set on one side of the semicircle of the fixing device 3, and a buckle 33 is set on the other side of the semicircle. The buckle 33 can connect the fixing device 3, ensuring that the fixing device 3 does not loosen and does not shift under vibration.
[0042] The fixing device 3 can provide additional mechanical stability, enhance the overall vibration resistance of the connecting device 1, and offset the effects of thermal expansion and contraction on the connection parts under high temperature conditions through the pre-tightening design, thus maintaining airtightness and stability.
[0043] In this embodiment, the connecting bracket 12 is securely fixed to the side of the reactor or the reserved mounting hole by bolts 121. The bracket has a flange 122 for easy docking with the fixing device 3; the connecting pipe 11 has connecting flanges 111 at both ends, which dock with the reactor inlet flange or aeration pipe flange; a sealing gasket 2 is installed at the flange docking point, and a reliable seal is achieved by tightening bolts; the bottom side of the fixing device 3 has a flange 31, which is bolted to the flange 122 on the connecting bracket 12; the connecting shaft 32 and the buckle 33 contact the outer wall of the connecting pipe 11, forming a circumferential and pre-tightening fixation of the connecting pipe to prevent loosening during operation. When the aeration pipe delivers gas into the connecting pipe 11, the diversion hole 112 can disperse and distribute the high-speed gas flow to various areas of the pipe, reducing dead zones or uneven mixing caused by local high-speed jets; after entering the reactor, the gas exhibits a more uniform distribution, improving the gas-liquid contact efficiency during the preparation of ferric chloride and stabilizing the reaction conditions.
[0044] The connection between flange 111 and gasket 2 ensures high-pressure sealing at the joint, reducing the risk of gas or liquid leakage. Connecting bracket 12 provides positioning and support for connecting pipe 11, while fixing device 3 further enhances the system's vibration resistance, maintaining stability even in high-temperature and chemically corrosive environments. The diversion holes 112, arranged spirally or in multiple layers, effectively improve aeration and promote the efficiency of ferric chloride preparation in the reactor. The flange and bolt connections simplify component assembly and disassembly; the snap-fit design also facilitates daily inspection, cleaning, and component replacement. The entire system is constructed from high-temperature and corrosion-resistant materials, enabling long-term stable operation in acidic or high-temperature environments used for ferric chloride preparation.
[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
