Description

Technical Field

[0001] This utility model relates to the field of ferric chloride synthesis equipment technology, and in particular to an enamel-lined reactor for ferric chloride preparation. Background Technology

[0002] Ferric chloride is an important inorganic chemical widely used in water treatment, printed circuit board manufacturing, dyes, catalysts, and other fields. Generally, high-purity iron filings are added to a reaction vessel along with a certain amount of water and stirred until homogeneous. Industrial-grade hydrochloric acid, typically at a concentration of 30%-37%, is then slowly added. Care must be taken to control the acid addition rate to ensure the reaction proceeds at a relatively low temperature. A large amount of heat is generated during the reaction, requiring cooling water to control the temperature, maintaining it at 60-80℃. After the reaction is complete, the mixture is allowed to stand for a period of time to allow the solid to precipitate; the supernatant is the ferric chloride solution.

[0003] However, existing reactors lack relevant temperature control components when preparing ferric chloride solutions, making it difficult to maintain the temperature within the optimal preparation temperature range of 60-80℃. Excessive temperature may lead to excessive pressure inside the reactor, while excessively low temperature may reduce reaction efficiency. Based on this, an enamel-lined reactor for preparing ferric chloride is proposed to solve the above problems. Utility Model Content

[0007] As a further improvement to the above solution, the liquid cooling heat dissipation mechanism includes a cooling water tank fixedly connected to the outside of the water tank, the upper end of the heat exchange tube passing through the side wall of the water tank and communicating with the inside of the cooling water tank, a water pump fixedly connected to the outside of the water tank, the lower end of the heat exchange tube passing through the side wall of the water tank and communicating with the output end of the water pump, the other side of the output end of the water pump communicating with the cooling water tank, and an air cooling heat dissipation mechanism being provided inside the cooling water tank.

[0008] As a further improvement to the above solution, the air-cooled heat dissipation mechanism includes multiple air-cooled pipes installed inside the cooling water tank. A mounting platform is fixedly connected to the side of the cooling water tank away from the water tank. Multiple fans are installed on the mounting platform. The air duct opening on the rear side of each fan is connected to one end of the air-cooled pipe.

[0009] As a further improvement to the above solution, the installation and fixing mechanism includes a mounting base fixedly connected to the lower side of the water tank, and multiple support legs are fixedly connected to the lower side of the multiple mounting bases.

[0010] As a further improvement to the above solution, the lower end of the enamel-lined kettle body is connected to a drain pipe, which passes downward through the water tank, and a solenoid valve is provided at the lower end of the drain pipe.

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

[0012] 1. This utility model uses a combination of air-cooled heat dissipation mechanism and liquid-cooled heat dissipation mechanism, and sets a heat exchange tube between the water tank and the enamel-lined kettle body. When iron reacts with concentrated hydrochloric acid and releases a large amount of heat, the heat inside the enamel-lined kettle body can be discharged through the heat exchange tube, so as to stabilize the reaction temperature within the range of 60-80 degrees Celsius and avoid safety accidents caused by excessive temperature and excessive internal pressure of the kettle body.

[0013] 2. This utility model controls the reaction temperature inside the enamel-lined reactor within the range of 60-80 degrees Celsius through a liquid cooling heat dissipation mechanism, achieving the optimal chemical temperature for the reaction between iron and concentrated hydrochloric acid, which is beneficial to improving the efficiency of the chemical reaction.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example:

[0021] Please combine Figures 1-3 This embodiment of a ferric chloride preparation enamel-lined reactor includes a water tank 3, which is a cylindrical structure with a coolant filling port on its upper side. In this embodiment, water is added to the water tank 3 as a coolant. An enamel-lined reactor body 11 is fixedly connected inside the water tank 3. The interior of the enamel-lined reactor body 11 is lined with ceramic to increase corrosion resistance. A heat exchange pipe 10 is provided between the outer side of the enamel-lined reactor body 11 and the inner side of the water tank 3. Please refer to... Figure 3 As shown, the heat exchange tube 10 has a spiral structure to increase the contact area. Both ends of the heat exchange tube 10 extend outwards from the water tank 3. The enameled vessel body 11 is equipped with a stirring mechanism inside. The water tank 3 is equipped with a liquid cooling heat dissipation mechanism on the outside. The water tank 3 is equipped with an installation and fixing mechanism on the lower side.

[0022] Please combine Figure 2 As shown, the stirring mechanism includes an upper cover 6 provided on the upper side of the enamel-lined vessel body 11. The upper cover 6 and the enamel-lined vessel body 11 are detachable and have good sealing performance. A servo motor 5 is fixedly connected to the upper side of the upper cover 6. A stirring rod 15 is fixedly connected to the output end of the servo motor 5. A stirring blade 14 is fixedly connected to the lower end of the stirring rod 15. A filling pipe 4 is connected to the upper cover 6.

[0023] Please combine Figure 3 As shown, the liquid cooling heat dissipation mechanism includes a cooling water tank 7 fixedly connected to the outside of the water tank 3. The upper end of the heat exchange pipe 10 passes through the side wall of the water tank 3 and communicates with the inside of the cooling water tank 7. A water pump 9 is fixedly connected to the outside of the water tank 3. The lower end of the heat exchange pipe 10 passes through the side wall of the water tank 3 and communicates with the output end of the water pump 9. The other side of the output end of the water pump 9 is connected to the cooling water tank 7. An air-cooled heat dissipation mechanism is provided inside the cooling water tank 7.

[0024] Please combine Figure 3As shown, the air-cooled heat dissipation mechanism includes two air-cooled pipes 12 installed inside the cooling water tank 7. The air-cooled pipes 12 are vortex-shaped hollow structures. A mounting platform 13 is fixedly connected to the side of the cooling water tank 7 away from the water tank 3. Two fans 8 are installed on the mounting platform 13. The air duct opening on the rear side of each fan 8 is connected to one end of the air-cooled pipe 12. The other end of the two air-cooled pipes 12 passes through the cooling water tank 7 and is connected to an exhaust pipe 16. When the fans 8 rotate, they can inject outside air into the air-cooled pipe 12 from the pipe near the center of the air-cooled pipe 12, and then transport it along the main body of the air-cooled pipe 12. During this process, the heat in the cooling water tank 7 is absorbed by heat conduction and finally discharged from the exhaust pipe 16.

[0025] Please combine Figure 1 As shown, the mounting and fixing mechanism includes a mounting base 1 fixedly connected to the lower side of the water tank 3. Multiple support legs are fixedly connected to the lower side of the three mounting bases 1. The mounting bases 1 and the water tank 3 are designed to be detachable.

[0026] Please combine Figure 3 As shown, the lower end of the enamel-lined vessel body 11 is connected to a drain pipe 2, which plays a certain role in fixing and supporting the vessel. The drain pipe 2 passes downward through the water tank 3, and a solenoid valve is installed at the lower end of the drain pipe 2 to control the liquid supply.

[0027] The implementation principle of the enamel-lined reactor for ferric chloride preparation in this embodiment is as follows: iron filings are added to the reactor, a certain amount of water is added, the servo motor 5 is started, and the stirring blade 14 is rotated by the stirring rod 15 to stir evenly. Then, hydrochloric acid is slowly added, and the acid addition rate is controlled so that the reaction is carried out at a low temperature. A large amount of heat is generated during the reaction. At this time, the water pump 9 is started to introduce the coolant in the cooling water tank 7 into the water tank 3 through the heat exchange pipe 10. Since the coolant in the water tank 3 has been added in advance, when the low-temperature coolant passes through the heat exchange pipe 10, the coolant in the heat exchange pipe 10 absorbs the heat in the water tank 3 and flows out from the other end, returning to the cooling water tank 7. When multiple fans 8 are started, the cold air from the outside is introduced into the air-cooled pipe 12. The air-cooled pipe 12 absorbs the heat of the high-temperature cooling water in the cooling water tank 7 by heat transfer and is discharged from the exhaust pipe 16 to achieve the effect of cooling and heat dissipation.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
