Abstract
Description
Technical Field
[0001] This utility model relates to the field of concentration equipment technology, and in particular to an evaporation and concentration equipment for titanium dioxide production. Background Technology
[0002] Titanium dioxide, as a crucial inorganic chemical product, plays an indispensable role in numerous industrial fields such as coatings, inks, papermaking, plastics and rubber, chemical fibers, and ceramics. Its main component is titanium dioxide, a polycrystalline compound with regularly arranged internal particles possessing a lattice structure, and it has a relatively low density. Currently, the main production processes for titanium dioxide include the sulfuric acid process and the chloride process.
[0003] In the production process of titanium dioxide, evaporation and concentration equipment is a crucial link. However, the evaporation and concentration equipment currently used in actual production has revealed a series of prominent problems. On the one hand, evaporation and concentration are time-consuming. This not only significantly prolongs the entire production cycle but also requires a continuous investment of a large amount of energy during the long evaporation and concentration process, greatly increasing production costs. On the other hand, uneven heating of the titanium liquid is a common problem. The titanium liquid in different parts of the equipment cannot receive a balanced heat supply during evaporation and concentration. Some areas of the titanium liquid may be underheated, resulting in slow evaporation and concentration and failing to reach the expected concentration on time; while other areas of the titanium liquid may be overheated, leading to adverse conditions such as component decomposition and impurity precipitation, seriously affecting the product quality of titanium dioxide. In view of this, this utility model proposes an evaporation and concentration device for titanium dioxide production. Utility Model Content
[0004] The purpose of this invention is to address the problems in the current titanium dioxide production process, such as the long evaporation and concentration time, which leads to longer production cycles, increased energy consumption and costs, and uneven heating of the titanium liquid, affecting product quality. This invention proposes an evaporation and concentration device for titanium dioxide production.
[0005] The technical solution of this utility model is as follows: An evaporation and concentration device for titanium dioxide production, comprising a hollow box; a heating component disposed in the box for heating liquid titanium with steam; a reciprocating mechanism installed on the box for driving the heating component to reciprocate within the box to heat the liquid titanium inside; and a stirring component disposed on the heating component for stirring the liquid titanium to ensure uniform heating.
[0006] Optionally, the heating assembly includes a heating tube disposed in the housing. The heating tube is arranged in a "U" shape, and connecting tubes are respectively connected to both sides of the heating tube. The connecting tubes are arranged in an L shape, and two sets of connecting tubes are respectively connected to the top and bottom of the heating tube. A movable tube is connected to the side of the two sets of connecting tubes that are far apart. The end of the movable tube that is far away from the connecting tube passes through the side wall of the housing and is equipped with a connector. The movable tube is slidably connected to the side of the housing. An intermediate tube is also installed in the heating tube.
[0007] Optionally, the reciprocating mechanism includes a mounting frame installed on one side of the housing. The mounting frame is U-shaped. A servo motor is installed on the side of the mounting frame away from the housing. The output end of the servo motor passes through the mounting frame and is fixedly connected to a rotating plate. A rotating wheel is rotatably connected to the side of the rotating plate away from the servo motor. A moving plate is slidably connected to the outside of the rotating wheel. The moving plate is on the same horizontal plane as the heating tube. A connecting block is fixedly connected to one end of the moving plate. The connecting block is fixedly connected to a set of moving tubes.
[0008] Optionally, the reciprocating mechanism further includes multiple sets of limiting blocks fixedly connected to the inner side of the heating tube, with limiting rods slidably connected in the limiting blocks, and the limiting rods fixedly connected to the inner wall of the box.
[0009] Optionally, the stirring assembly includes two sets of rotating rings rotatably connected to the outside of the intermediate tube. Two sets of connecting plates are fixedly connected to the outside of each set of rotating rings.

[0012] Optionally, a feed inlet is installed on the top of the box, and a discharge pipe is connected to the side of the box.
[0013] In summary, this application includes at least one of the following beneficial technical effects:
[0014] This invention utilizes a heating tube and an intermediate tube to allow steam to fully act on the titanium liquid, expanding the heating area. Simultaneously, a servo motor drives the heating components to reciprocate within the chamber, ensuring that the titanium liquid is heated from all angles, avoiding slow evaporation caused by uneven heating in certain areas. When the heating components move, the stirring component achieves autonomous rotation through the meshing of gears and racks, continuously stirring the titanium liquid, promoting heat transfer and liquid mixing, significantly shortening the time required for evaporation and concentration, and effectively improving production efficiency.
[0015] Furthermore, by using a limiting block and a limiting rod, the movement of the heating component is ensured to be smooth, allowing the titanium liquid to be heated evenly. This reduces problems such as component decomposition and impurity precipitation caused by overheating or underheating. During the heating process, the stirring component can not only rotate and stir, but also move with the heating component, further ensuring the uniform mixing of the titanium liquid. This makes the various reactions of the titanium liquid more complete and stable during the evaporation and concentration process, ensuring the quality of titanium dioxide products from the source and reducing the defect rate.
[0016] In summary, this invention solves the problems of time-consuming evaporation and concentration and uneven heating of titanium liquid, thereby shortening the production cycle, reducing energy consumption costs, and ensuring the quality of titanium dioxide products. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] Example:
[0032] like Figure 1 and Figure 2 As shown, the present invention proposes an evaporation and concentration device for titanium dioxide production, comprising a hollow housing 1, with an inlet 11 installed on the top of the housing 1 to facilitate the addition of liquid titanium to the housing 1. An outlet pipe 12 is connected to the side of the housing 1, and the outlet pipe 12 is equipped with a shut-off valve to discharge the liquid titanium.
[0033] For further details, please refer to Figure 2 and Figure 3The aforementioned concentration equipment includes a heating assembly 2 housed within a casing 1. The heating assembly 2 heats the molten titanium using steam. The heating assembly 2 includes a heating pipe 21 housed within the casing 1. The heating pipe 21 is U-shaped, with connecting pipes 22 connected to both sides of the heating pipe 21. The connecting pipes 22 are L-shaped, connecting the top and bottom of the heating pipe 21 respectively, allowing steam to pass through. A movable pipe 23 is connected to the side of each connecting pipe 22 that is furthest from the connecting pipe 22. The end of the movable pipe 23 furthest from the connecting pipe 22 penetrates the side wall of the casing 1 and is fitted with a connector 24, facilitating connection to a steam pipe. The movable pipe 23 is slidably connected to the side of the casing 1. An intermediate pipe 25 is also installed within the heating pipe 21, through which steam also passes.
[0034] Furthermore, such as Figures 1 to 3 As shown, the above-mentioned concentration equipment also includes a reciprocating mechanism 3 installed on the housing 1. The reciprocating mechanism 3 is used to drive the heating component 2 to reciprocate within the housing 1 to heat the internal titanium liquid. The reciprocating mechanism 3 includes a mounting frame 31 installed on one side of the housing 1. The mounting frame 31 is U-shaped and its position is fixed. A servo motor 32 is installed on the side of the mounting frame 31 away from the housing 1. The output end of the servo motor 32 passes through the mounting frame 31 and is fixedly connected to a rotating plate 33. After the servo motor 32 is started, it drives the rotating plate 33 to rotate. A rotating wheel 34 is rotatably connected to the side of the rotating plate 33 away from the servo motor 32. When the rotating plate 33 rotates, it drives the rotating wheel 34 to perform circular motion. A movable plate 35 is slidably connected to the outside of the rotating wheel 34. When the rotating wheel 34 performs circular motion, it drives the movable plate 35 to perform reciprocating motion. The moving plate 35 and the heating tube 21 are on the same horizontal plane. A connecting block 36 is fixedly connected to one end of the moving plate 35. The connecting block 36 is fixedly connected to a set of moving tubes 23. The moving plate 35 drives the heating assembly 2 to reciprocate through the connecting block 36, so that the heating tube 21 moves inside the box 1 to improve the uniformity of titanium liquid heating. The reciprocating mechanism 3 also includes multiple sets of limiting blocks 37 fixedly connected to the inner side of the heating tube 21. Limiting rods 38 are slidably connected in the limiting blocks 37. The limiting rods 38 are fixedly connected to the inner wall of the box 1. The setting of the limiting blocks 37 and the limiting rods 38 makes the movement of the heating tube 21 smooth.
[0035] Finally, please see Figures 2 to 4The aforementioned concentration equipment also includes a stirring assembly 4 mounted on the heating assembly 2. The stirring assembly 4 is used to stir the titanium liquid to ensure uniform heating. The stirring assembly 4 includes two sets of rotating rings 41 rotatably connected to the outside of the intermediate tube 25. Each end of the two sets of rotating rings 41 is provided with a limiting ring 44, which is fixedly connected to the outer ring of the intermediate tube 25. The limiting rings 44 keep the rotating rings 41 rotating in their original position. Two sets of connecting plates 42 are fixedly connected to the outside of the two sets of rotating rings 41. The ends of the two sets of connecting plates 42 on the same side away from the rotating rings 41 are fixedly connected to a stirring rod 43. When the rotating rings 41 rotate, they drive the connecting plates 42 and the stirring rod 43 to rotate synchronously to stir the titanium liquid in the tank 1. At the same time, the rotating rings 41 and the connecting plates 42 also move synchronously with the heating assembly 2 to ensure uniform mixing of the titanium liquid. A gear 45 is fixedly connected to the outer ring of one set of rotating rings 41. When the gear 45 rotates, it drives the rotating rings 41 to rotate synchronously. A rack 46 is provided on one side of the gear 45 to mesh with it. The rack 46 is fixedly connected to the inner wall of the housing 1. The position of the rack 46 is fixed, so that when the heating tube 21 and the intermediate tube 25 move, the gear 45 is driven to move. When the gear 45 moves, it meshes with the rack 46 and rotates, which in turn drives the rotating ring 41 to rotate. The gear 45 is located on the side of one set of connecting plates 42 away from the other set of connecting plates 42 to prevent the rack 46 from interfering with the rotation of the stirring rod 43.
[0036] In this embodiment, a steam pipe is connected to connector 24. Steam passes through moving pipe 23 and connecting pipe 22, entering the heating pipe 21 and intermediate pipe 25 arranged in a "U" shape. The heating assembly 2 is ready to heat the titanium liquid in the box 1. The servo motor 32 is started, and its output end drives the rotating plate 33 to rotate. The rotating wheel 34 on the rotating plate 33 then performs a circular motion. The circular motion of the rotating wheel 34 drives the moving plate 35 to reciprocate. The moving plate 35 is connected to the moving pipe 23 through connecting block 36, thereby driving the entire heating assembly 2 to reciprocate within the box 1. During the movement of the heating assembly 2, the limiting block 37 slides along the limiting rod 38 to ensure that the heating pipe 21 moves smoothly and that the titanium liquid is heated more evenly. When the heating assembly 2 moves, the gear 45 on the outside of the intermediate pipe 25 moves accordingly. Since the gear 45 meshes with the rack 46 fixed to the inner wall of the box 1, the gear 45 rotates during the movement, thereby driving the rotating ring 41 fixedly connected to it to rotate. The limiting rings 44 at both ends of the rotating ring 41 ensure that it rotates in its original position. When the rotating ring 41 rotates, it drives the connecting plate 42 and the stirring rod 43 fixedly connected to the outside to rotate synchronously, stirring the titanium liquid in the box 1. At the same time, the rotating ring 41 and the connecting plate 42 also move synchronously with the heating component 2, further ensuring that the titanium liquid is mixed evenly and promoting uniform heating.
[0037] Under the continuous heating of heating component 2 and the constant stirring of stirring component 4, the titanium liquid undergoes evaporation and concentration within the tank 1. Steam continuously provides heat to the titanium liquid, and stirring component 4 ensures thorough mixing and uniform heating, accelerating the evaporation and concentration process. Once the titanium liquid reaches the desired evaporation and concentration effect, the shut-off valve on the discharge pipe 12 is opened, and the concentrated titanium liquid is discharged from the tank 1 through the discharge pipe 12, completing the entire evaporation and concentration process.
[0038] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
