Description

Technical Field

[0001] The utility model relates to the technical field of enamel reaction kettles, in particular to an enamel reaction kettle for producing ferric chloride. Background Art

[0002] When producing ferric chloride, the raw materials need to be put into a dissolving kettle for acid dissolution, and then passed into a filter press for solid-liquid separation, the waste residue is discharged, and the filtrate enters the ferric chloride reactor for catalytic oxidation. The produced materials are then passed into the material pool for storage. The reactor is an important reaction device for the production of ferric chloride. During the reaction, hydrochloric acid, oxygen, sodium nitrite solution, etc. need to be pumped into the reactor, and the gas during the reaction is discharged after treatment. Usually, an enamel reactor is selected. The enamel reactor is a composite material product made of glass containing high silicon dioxide, which is lined on the inner surface of a steel container and firmly adhered to the metal surface through high-temperature calcination. During production, the filtrate needs to be effectively mixed with the additive liquid to promote the reaction of ferric chloride production.

[0003] According to the patent number CN 217663352 U, a glass-enamel reactor for producing ferric chloride is disclosed. The glass-enamel reactor disperses liquid into the reactor through an ejector, so that the liquid is dispersed and contacts with the gas inside to achieve a rapid reaction. The reaction liquid can be repeatedly pumped into the reactor for mixed reaction through a circulating pump. However, the rotating rod for stirring of the device is installed horizontally in the middle section inside the reactor. By driving the rotating rod to rotate, the reactants are mixed with the cooperation of the stirring blades. The horizontal stirring easily causes a part of the reactants to accumulate at the bottom end of the reactor, resulting in poor mixing effect and insufficient reaction. The rotating shaft of the existing device is installed on the inner wall of the reactor, and a plurality of blades are arranged at the bottom end of the reactor to mix the reactants again before entering the discharge pipe. However, the rotating shaft, the stirring blades and the plurality of blades for diversion are all arranged inside the reactor. After the reactor is used, it is not convenient to clean the complex components inside the reactor, which affects the result of the next product reaction. For this reason, we propose a glass-enamel reactor for producing ferric chloride. Utility Model Content

[0026] It should be noted that the reaction components in the kettle body 2 are all installed on the mounting cover 3. Through the detachable connection between the mounting cover 3 and the kettle body 2, when the reaction is completed, it is only necessary to remove the mounting cover 3 to fully clean the internal components for subsequent use.

[0027] A primary mixing mechanism 19 is arranged in the mounting cover 3 , and a stirring and mixing mechanism 20 is arranged in the kettle body 2 .

[0028] It should be noted that when the utility model is used, the liquid to be reacted is divided into two parts, one part is input into the kettle body 2 through the first liquid inlet pipe 6, and the other part is input into the kettle body 2 through the second liquid inlet pipe 16. The liquid in the first liquid inlet pipe 6 is placed inside the mounting cover 3, and is sprayed to the multiple arc-shaped blades 12 outside the fixed cylinder 11 through the high-pressure nozzles 8 on the multiple branch pipes 7. The hollow tube 10 rotates under the impact of the liquid. After the liquid is sprayed to the outside of the arc-shaped blades 12, due to the setting of the arc surface on the outside of the arc-shaped blades 12, the liquid after the impact forms multiple small droplets that explode toward the inner wall of the mounting cover 3, so that the liquid droplets are fully mixed with the kettle body 2. The gas inside contacts and reacts. At the same time, the liquid in the second liquid inlet pipe 16 enters the hollow tube 10 and is placed in the liquid storage box 13 through the hollow tube 10. As the hollow tube 10 rotates, the liquid is sprayed toward the inner wall of the mounting cover 3 through the nozzle 14 on the liquid storage box 13. The liquid contacts and collides with the inner wall of the mounting cover 3 to form a plurality of small water droplets that can fully contact and react with the gas inside the kettle body 2. At the same time, the rotating motor 5 works to rotate the two stirring shafts 4 inside the kettle body 2. The stirring blades 22 on the outer side of the stirring shaft 4 are matched to achieve the mixed liquid inside the kettle body 2 to be fully stirred and mixed, thereby achieving the effect of a one-time full reaction.

[0029] The stirring and mixing mechanism 20 includes a stirring shaft 4, a pulley 21 and a rotating motor 5.

The stirring and mixing mechanism 20 can fully stir the reactants inside the kettle body 1 to make the reaction more complete.

[0030] It should be noted that, through the control system set up in the device, the rotating motor 5 is controlled to rotate the two stirring shafts 4 inside the kettle body 2, and the stirring blades 22 outside the stirring shafts 4 are matched to achieve sufficient stirring and mixing of the mixed liquid inside the kettle body 2.

[0031] The primary mixing mechanism 19 includes a hollow tube 10, a fixed cylinder 11, arc-shaped blades 12, a liquid storage box 13, a nozzle 14, a rotary joint 15 and a second liquid inlet pipe 16. The side of the mounting cover 3 located inside the kettle body 2 is rotatably connected to the hollow tube 10 through a bearing, the outer side of the hollow tube 10 is fixedly connected to the fixed cylinder 11 through a mounting rod, the outer side of the fixed cylinder 11 is equidistantly fixedly connected to the arc-shaped blades 12, the top of the hollow tube 10 passes through the mounting cover 3, the end of the hollow tube 10 located outside the mounting cover 3 is fixedly installed with a rotary joint 15, and the hollow tube 10 is connected to the second liquid inlet pipe 16 through the rotary joint 15, the end of the hollow tube 10 located inside the mounting cover 3 is fixedly connected to the liquid storage box 13, and the outer side of the liquid storage box 13 is equidistantly connected to the nozzle 14, the primary mixing mechanism 19 can promote the full reaction of the liquid when it enters the kettle body 2.

[0032] It should be noted that the liquid to be reacted is divided into two parts. One part of the reaction liquid enters the hollow tube 10 through the liquid in the second liquid inlet pipe 16, and is placed in the liquid storage box 13 through the hollow tube 10. The liquid is sprayed toward the inner wall of the installation cover 3 through the nozzle 14 on the liquid storage box 13. The liquid contacts and collides with the inner wall of the installation cover 3 to form a plurality of small water droplets that can fully contact and react with the gas inside the kettle body 2.

[0033] The outer side of the mounting cover 3 is connected to a first liquid inlet pipe 6, and the first liquid inlet pipe 6 is wound and fixed on the outer side of the mounting cover 3. Branch pipes 7 are fixedly installed at equal intervals on the inner wall of the mounting cover 3, and the ends of the branch pipes 7 pass through the mounting cover 3 and are connected with the inside of the first liquid inlet pipe 6. A high-pressure nozzle 8 is fixedly installed at one end of the branch pipe 7 located inside the mounting cover 3, and the nozzle of the high-pressure nozzle 8 is arranged toward the outside of the arc-shaped fan blades 12. The hollow tube 10, the fixed cylinder 11 and the arc-shaped fan blades 12 are all made of lightweight materials, so that when the high-pressure nozzle 8 impacts the arc-shaped fan blades 12, the hollow tube 10 can be prompted to rotate rapidly.

[0034] It should be noted that a part of the liquid is input into the kettle body 2 through the first liquid inlet pipe 6, and the other part is input into the kettle body 2 through the second liquid inlet pipe 16. The liquid in the first liquid inlet pipe 6 is placed inside the mounting cover 3, and is sprayed toward the multiple arc-shaped blades 12 outside the fixed cylinder 11 through the high-pressure nozzles 8 on the multiple branch pipes 7. The hollow tube 10 rotates under the impact of the liquid. After the liquid is sprayed toward the outside of the arc-shaped blades 12, due to the arc-shaped surface setting of the outer side of the arc-shaped blades 12, the liquid after the impact forms multiple droplets that explode toward the inner wall of the mounting cover 3, so that the liquid droplets are fully in contact with the gas inside the kettle body 2 to react.

[0035] The outer side of the stirring shaft 4 is fixedly connected with stirring blades 22 at equal intervals.

[0036] It should be noted that a plurality of stirring blades 22 are provided on the outside of the stirring shaft 4. When the stirring shaft 4 is driven to rotate, the stirring blades 22 on the outside of the stirring shaft 4 cooperate with the stirring blades 22 to stir the reactants inside the kettle body 1, so that the liquid can fully collide with the two stirring shafts 4 and the plurality of stirring blades 22 on the outside of the two stirring shafts 4 during the circulation process, thereby being able to perform secondary mixing of the reactants and make them react fully.

[0037] The cross section of the bottom end of the kettle body 2 is an arc-shaped structure.

[0038] It should be noted that the bottom end of the kettle body 2 is set to a hemispherical structure. When the liquid after the internal reaction needs to be discharged, the liquid can accumulate at the bottom end of the kettle body 2 under the action of gravity, so that all the liquid inside the kettle body 1 can be discharged conveniently.

[0039] A liquid outlet 17 is installed at the bottom center of the kettle body 2 , and a control valve 18 is installed outside the liquid outlet 17 .

[0040] It should be noted that the discharge of the mixture after the reaction is facilitated by the liquid outlet 17, and the on-off control of the liquid outlet 17 is facilitated by the control valve 18. When operating the reaction mixture reaction, the control valve 18 on the liquid outlet 17 is controlled to be closed, and when collecting, the control valve 18 on the liquid outlet 17 is controlled to be open.

[0041] There are six nozzles 14 outside the liquid storage box 13, and the nozzles 14 are arranged obliquely. The nozzles 14 are installed outside the liquid storage box 13 in a centrally symmetrical manner.

[0042] It should be noted that when the hollow tube 10 rotates, it can drive the liquid storage box 13 to rotate, so that the multiple nozzles 14 on the outside thereof rotate circumferentially, and the inclined nozzles 14 can spray the liquid toward the inner wall of the mounting cover 3, so that the liquid hits the inner wall of the mounting cover 3 to form multiple small water droplets, thereby increasing the contact area between the liquid and the gas and making the reaction more complete.
