Description

Technical Field

[0001] This utility model relates to the technical field of titanium dioxide, and in particular to a distillation and purification device for titanium dioxide production. Background Technology

[0002] Titanium dioxide is an important inorganic chemical pigment, primarily composed of titanium dioxide. There are two main production processes for titanium dioxide: the sulfuric acid process and the chloride process. Titanium dioxide has significant applications in industries such as coatings, inks, papermaking, plastics and rubber, synthetic fibers, and ceramics.

[0003] Distillation purification is a crucial step in the production of titanium dioxide. In traditional distillation equipment, the steam often fails to fully contact the condensation surface during the condensation process, resulting in poor condensation efficiency. Some steam fails to condense into liquid in time, leading to resource waste. Furthermore, during distillation, materials tend to accumulate on the inner wall and bottom of the distillation vessel, forming residues that are difficult to remove. This residue buildup can negatively impact the efficiency of subsequent distillations.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a distillation purification device for titanium dioxide production is proposed. Utility Model Content

[0021] (3) This utility model provides a distillation purification device for titanium dioxide production. By setting the protective shell and heat dissipation holes at the bottom of the distillation kettle, the motor can be effectively protected from the effects of high temperature and humid environment, while ensuring the heat dissipation performance of the motor.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, a distillation purification device for titanium dioxide production includes: a distillation kettle 1, a flow guiding mechanism 3 disposed on the inner wall of the top of the distillation kettle 1, and a stirring mechanism 5 disposed on the inner wall of the bottom of the distillation kettle 1.

[0030] like Figures 2-3 As shown, the flow guiding mechanism 3 includes: a flow guiding plate 301, a flow guiding surface 302 disposed at the bottom of the flow guiding plate 301, a plurality of flow guiding strips 303 disposed at the bottom of the flow guiding surface 302, a fixing rod 304 disposed at the bottom of the flow guiding surface 302, a plurality of connecting rods 306 disposed on the outer circumference of the fixing rod 304, a common liquid collecting hopper 305 disposed at the bottom of the plurality of connecting rods 306, and a flow guiding pipe 307 disposed at the bottom of the liquid collecting hopper 305;

[0031] The guide plate 301 is fixedly connected to the top inner wall of the distillation vessel 1, the guide surface 302 is fixedly connected to the top of the guide plate 301, the top of the fixed rod 304 is fixedly connected to the bottom center of the guide surface 302, the top ends of several connecting rods 306 are fixedly connected to the outer circumference of the fixed rod 304, the inner circumference of the liquid collecting hopper 305 is fixedly connected to the bottom of several connecting rods 306, one end of the guide pipe 307 is fixedly connected to the bottom of the liquid collecting hopper 305, and the other end of the guide pipe 307 penetrates the distillation vessel 1.

[0032] Several guide strips 303 are fixedly connected to the top of the guide surface 302, and one end of each guide strip 303 is located above the liquid collection hopper 305.

[0033] It should be noted that the flow guiding mechanism 3 enables both gas flow guidance and liquid collection. The flow guiding plate 301 is installed on the inner top wall of the distillation vessel 1, providing a solid foundation for the flow guiding process, while the flow guiding surface 302 facilitates the smooth flow of gas after condensation into liquid. Simultaneously, several flow guiding strips 303 at the bottom of the flow guiding surface 302 not only widen the flow path of the condensed liquid but also ensure that the liquid is guided uniformly and orderly to the collection hopper 305, effectively preventing liquid accumulation and stagnation, and significantly improving the flow guiding efficiency. The collection hopper 305 facilitates liquid collection, while the flow guiding pipe 307 penetrates the distillation vessel 1, simplifying the liquid collection process, thereby significantly improving the purity and quality of titanium dioxide.

[0034] like Figure 2 and Figure 4 As shown, the stirring mechanism 5 includes: a motor 502, a rotating block 504 disposed on the inner wall of the bottom of the distillation vessel 1, a plurality of scrapers 505 disposed on the outer circumference of the rotating block 504, and a plurality of stirring rods 508 disposed on the upper surface of the rotating block 504.

[0035] Rotating block 504 is rotatably connected to the bottom inner wall of distillation vessel 1. Motor 502 is fixedly connected to the bottom of distillation vessel 1. One end of the output shaft of motor 502 passes through distillation vessel 1 and is fixedly connected to the bottom of rotating block 504. One side of several scrapers 505 is fixedly connected to the outer circumference of rotating block 504. The other end of several scrapers 505 is fixedly connected to the same connecting frame 507. Several grooves 506 are opened on one side of several scrapers 505.

[0036] Several scrapers 505 are all at 45°, and the bottom of several scrapers 505 are tightly fitted with the bottom inner wall of the distillation vessel 1. The outer circumference of the connecting frame 507 is tightly fitted with the inner circumference of the distillation vessel 1. A protective shell 501 is fixedly connected to the bottom of the distillation vessel 1. The motor 502 is located inside the protective shell 501. Several through heat dissipation holes 503 are opened on the outer circumference of the protective shell 501.

[0037] The bottom of several stirring rods 508 is fixedly connected to the upper surface of the rotating block 504, and the top of several stirring rods 508 is fixedly connected to the same connecting ring 509.

[0038] It should be noted that the motor 502 is securely fixed to the bottom of the distillation vessel 1 and placed within a protective shell 501 for protection. Simultaneously, the heat dissipation holes 503 on the protective shell 501 ensure effective heat dissipation during motor 502 operation. The output shaft of the motor 502 penetrates the bottom of the distillation vessel 1 and connects to the rotating block 504, driving its rotation. Several 45° inclined scrapers 505 are fixedly installed on the outer circumference of the rotating block 504. The bottoms of the scrapers 505 are in close contact with the inner wall of the distillation vessel 1, effectively scraping and removing residual material and preventing material accumulation. The grooves 506 on the scrapers 505 facilitate smoother material flow during scraping, preventing blockages. In addition, the other end of the scraper 505 is in close contact with the inner circumference of the distillation vessel 1 through the connecting frame 507, which further enhances the scraping effect. On the other hand, the stirring rod 508 and the connecting ring 509 fixedly connected to the top of the rotating block 504 form a stirring system, which realizes the uniform mixing of materials in the distillation vessel 1, thereby improving the efficiency and quality of distillation and purification, and also ensuring the convenience and safety of operation.

[0039] like Figures 1-3 As shown, the bottom pipe of the distillation vessel 1 is connected to the outlet pipe 4. The end of the guide pipe 307 located outside the distillation vessel 1 is connected to the outer circumferential wall pipe of the outlet pipe 4. A valve is provided inside the outlet pipe 4. The outer circumferential wall pipe of the distillation vessel 1 is connected to the feed hopper 2. Several support rods 6 are fixedly connected to the bottom of the distillation vessel 1.

[0040] It should be noted that the bottom of the distillation vessel 1 is connected to the outlet pipe 4 via a pipeline, and the guide pipe 307 is connected at one end outside the distillation vessel 1 to the outer circumferential wall of the outlet pipe 4, ensuring that the condensate collected from the collection hopper 305 can be smoothly discharged. A valve inside the outlet pipe 4 provides control over the material flow. Simultaneously, the outer circumferential wall of the distillation vessel 1 is connected to the feed hopper 2 via a pipeline, facilitating the input of raw materials. Several support rods 6 provide structural support for the device body and also ensure the stability of the distillation vessel 1 during operation.

[0041] In use, the material to be distilled is fed into the distillation vessel 1 through the feed hopper 2. During distillation, the distillation vessel 1 is heated, and as the temperature rises, the material begins to evaporate and generate steam. The steam rises inside the distillation vessel 1 and comes into contact with the guide plate 301 and guide surface 302 of the flow guiding mechanism 3. The steam flows to the collection hopper 305 via the fixed rod 304 on the guide surface 302. In the collection hopper 305, the condensed liquid gathers and is ready to be discharged through the guide pipe 307. When the condensed liquid in the collection hopper 305 reaches a certain amount, the valve in the discharge pipe 4 is opened, allowing the condensed liquid to be smoothly discharged through the guide pipe 307 and the discharge pipe 4. During the distillation process, the motor 502 of the stirring mechanism 5 runs continuously, causing the output shaft of the motor 502 to rotate. The rotation of the output shaft of the motor 502 drives the rotating block 504 and its scraper 505 and stirring rod 508 to rotate. The rotation of the scraper 505 helps to scrape off the residual material at the bottom of the distillation vessel 1, preventing material accumulation and blockage. Meanwhile, the rotation of the stirring rod 508 ensures that the materials are uniformly mixed in the distillation vessel 1, thereby improving the distillation efficiency.

[0042] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
