Description

Technical Field

[0001] This utility model relates to the field of bromine extraction technology, specifically a device for extracting bromine from low-content brine. Background Technology

[0002] Bromine extraction refers to the process of extracting elemental bromine from seawater. Bromine and its derivatives have important applications in the pharmaceutical industry, flame retardants, drilling fluids, and other fields. Therefore, bromine extraction technology has significant economic value. Brine or salt brine can be classified into two types according to its burial location: shallow brine and deep brine. Deep brine is generally located deep in the strata and is high-mineralized groundwater. This type of brine is buried at a greater depth and has a highly sealed characteristic. Low-content brine is often used for bromine extraction, thus requiring a bromine extraction device for low-content brine.

[0003] When operators extract bromine from low-content brine, they often use corresponding low-content brine bromine extraction devices. Although the existing devices can achieve the purpose of bromine extraction, in actual use, they mostly adopt the static reaction bromine extraction method, which may reduce the efficiency of bromine extraction. In addition, they lack a filtration mechanism for low-content brine, and cannot filter out solid impurities in the brine, which may interfere with subsequent bromine extraction processes, thus reducing their practicality. Utility Model Content

[0004] The purpose of this invention is to provide a bromine extraction device for low-content brine, addressing the issue raised in the background section where operators often use corresponding bromine extraction devices for low-content brine. Although existing devices can achieve bromine extraction, they often employ static reaction extraction methods, which may reduce extraction efficiency. Furthermore, they lack filtration mechanisms for low-content brine, failing to filter solid impurities, which may interfere with subsequent bromine extraction processes, thus reducing practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-content brine bromine extraction device, comprising a base plate, with support frames fixedly installed on both sides of the top of the base plate, a reaction tank fixedly installed inside the support frames, a feed inlet on the top of the reaction tank, a rotating shaft rotatably installed on one side of the inside of the reaction tank, a stirring rod fixedly installed around the surface of the rotating shaft, rotating rods fixedly installed around both sides of the surface of the rotating shaft, a scraper fixedly installed on one side of each rotating rod, a motor fixedly installed on one side of the reaction tank, and the output end of the motor passing through the reaction tank and fixedly connected to one side of the rotating shaft.

[0006] Preferably, a circular tube is fixedly installed on the other side of the reaction vessel, and one side of the circular tube penetrates the reaction vessel and extends to the inner surface of the reaction vessel.

[0007] Preferably, a vertical plate is fixedly installed on the top of the base plate, a filter box is fixedly installed on one end of the vertical plate, a circular groove is opened at the bottom of the filter box, a hopper is fixedly installed at the bottom of the filter box, and a vertical pipe is fixedly installed at the bottom of the hopper.

[0008] Preferably, a fixing plate is fixedly installed on both sides of the inner side of the circular groove, and a slot is opened inside the fixing plate, and a locking block is movably installed inside the slot.

[0009] Preferably, a filter plate is fixedly installed on the top of the card block, filter holes are evenly spaced inside the filter plate, and handles are fixedly installed on both sides of the top of the filter plate.

[0010] Preferably, a bracket is fixedly installed at each of the four corners of the bottom of the base plate, and the number of brackets is four, and the four brackets are the same size.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this low-content brine bromine extraction device, during daily use, the operator injects brine into the reaction tank through the feed inlet, then starts the motor. The motor's operation causes the shaft to rotate, which in turn drives the rotating rod to rotate, which in turn drives the scraper to rotate, thus preventing the brine from sticking to the inner wall. At the same time, the shaft drives the stirring rod to rotate, and then the catalyst is added to the brine. This operation method uses stirring to accelerate the reaction rate, ensuring that the brine ions and oxidant come into full contact, allowing the oxidation reaction to proceed more evenly and rapidly.

[0013] This low-content brine bromine extraction device, during daily use, involves the operator sliding the handle, which in turn causes the filter plate to slide. The filter plate then moves the locking block, placing the filter plate on top of the fixing plate and the locking block inside the slot. Simultaneously, brine is injected into the filter box, where the filter holes filter out solid impurities. The filtered brine flows through a circular trough into the hopper, and then through a vertical pipe and inlet into the reaction tank. This operation method effectively filters impurities in the brine, reducing interference with subsequent bromine extraction processes. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a low-content brine bromine extraction device, including a base plate 1, with support frames 2 fixedly installed on both sides of the top of the base plate 1. A reaction tank 3 is fixedly installed inside the support frames 2, which support the reaction tank 3. The reaction tank 3 provides a reaction space for the brine and catalyst. A feed inlet 4 is opened on the top of the reaction tank 3. A rotating shaft 5 is rotatably installed on one side of the inside of the reaction tank 3. A stirring rod 6 is fixedly installed around the surface of the rotating shaft 5. Brine can be fed into the inside of the reaction tank 3 through the feed inlet 4. When the rotating shaft 5 rotates, it drives the stirring rod 6 to rotate, thereby accelerating the reaction efficiency. A stirring rod 6 is fixedly installed around the surface of the rotating shaft 5. There is a rotating rod 7, and a scraper 8 is fixedly installed on one side of the rotating rod 7. When the rotating shaft 5 rotates, it will drive the rotating rod 7 to rotate, which in turn will drive the scraper 8 to rotate, thereby preventing the brine from sticking to the inner wall of the reaction tank 3. A motor 9 is fixedly installed on one side of the reaction tank 3, and the output end of the motor 9 passes through the reaction tank 3 and is fixedly connected to one side of the rotating shaft 5. When the motor 9 is running, it will cause the rotating shaft 5 to rotate, thereby improving its operating efficiency. A round pipe 10 is fixedly installed on the other side of the reaction tank 3, and one side of the round pipe 10 passes through the reaction tank 3 and extends to the inner surface of the reaction tank 3. The round pipe 10 is in a closed state during the reaction, and the brine can be discharged through it after the reaction is completed.

[0021] A vertical plate 11 is fixedly installed on the top of the base plate 1. A filter box 12 is fixedly installed at one end of the vertical plate 11. The filter box 12 is located above the reaction tank 3. Brine can be injected into the filter box 12 for filtration. A circular groove 13 is opened at the bottom of the filter box 12. A hopper 14 is fixedly installed at the bottom of the filter box 12, and a vertical pipe 15 is fixedly installed at the bottom of the hopper 14. The filtered brine will flow through the circular groove 13 into the hopper 14, and then flow through the vertical pipe 15 and the feed inlet 4 into the reaction tank 3. Fixing plates 16 are fixedly installed on both sides of the inside of the circular groove 13. A slot 17 is opened inside the fixed plate 16, and a locking block 18 is movably installed inside the slot 17. The slot 17 and the locking block 18 are connected to each other. The design of the slot 17 and the block 18 is compatible, and the filter plate 19 can be easily installed. The filter plate 19 is fixedly installed on the top of the block 18. The filter plate 19 has filter holes 20 evenly spaced inside. Impurities in the brine can be filtered through the filter plate 19 and the filter holes 20, thereby reducing interference with the subsequent bromine extraction process. Handles 21 are fixedly installed on both sides of the top of the filter plate 19. The design of the handles 21 makes it easy to pick up and put down the filter plate 19, making it more convenient. Supports 22 are fixedly installed at the four corners of the bottom of the base plate 1. There are four supports 22, and the four supports 22 are the same size. The design of the supports 22 makes it more stable, thereby increasing its stability.

[0022] Working principle: First, the operator slides handle 21, which causes filter plate 19 to slide. Filter plate 19 then causes locking block 18 to slide, placing filter plate 19 on top of fixing plate 16 and locking block 18 inside locking slot 17. This allows filter plate 19 to be installed. Simultaneously, brine is injected into filter box 12, allowing filter holes 20 to filter solid impurities in the brine. The filtered brine flows through circular trough 13 into hopper 14, and then through vertical pipe 15 and feed inlet. 4 flows into the interior of reaction tank 3 to filter the brine. Then, motor 9 is started, and the operation of motor 9 will cause the rotating shaft 5 to rotate. At this time, the rotating shaft 5 will drive the rotating rod 7 to rotate, and the rotating rod 7 will drive the scraper 8 to rotate, thereby preventing the brine from sticking to the inner wall. At the same time, the rotating shaft 5 will drive the stirring rod 6 to rotate, and then the catalyst will be placed in the brine to accelerate the reaction efficiency. The generated bromine needs to be carried out by the stripping gas, and then converted into bromide enrichment by the absorption liquid. Finally, bromine is obtained through secondary oxidation and purification.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
