[0002] Titanium dioxide is an important inorganic chemical product, mainly composed of titanium dioxide. It is widely used in coatings, plastics, papermaking, inks, chemical fibers, cosmetics, food, and pharmaceuticals. Titanium dioxide production is mainly divided into the sulfuric acid process and the chloride process. The sulfuric acid process requires the use of mineral powder raw materials mixed with concentrated sulfuric acid.
[0003] When using titanium dioxide batching equipment, attention must be paid to local overheating. If local overheating occurs inside the titanium dioxide batching equipment, titanium liquid hydrolysis is likely to occur. Local overheating can also lead to uncontrolled reaction, reduced product quality, such as coarse particles, uneven crystal structure, equipment corrosion, or even safety accidents, affecting the production efficiency of titanium dioxide.
[0004] There is an urgent need for a batching device for titanium dioxide mineral powder raw materials to solve the technical defects mentioned above. Utility Model Content
[0005] The purpose of this invention is to provide a batching device for titanium dioxide mineral powder raw materials, so as to solve the problem of local overheating affecting production quality mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a batching device for titanium dioxide mineral powder raw materials, comprising a batching tank, a jacket fixedly installed on the outside of the batching tank, five sets of cooling water pipes fixedly connected inside the jacket, an inlet and outlet water pipe fixedly connected to the left side of the jacket, a temperature sensor fixedly connected inside the jacket, a detachable sealing cover installed on the top of the batching tank, a feeding port fixedly connected to the left side of the top of the sealing cover, a drive motor fixedly installed at the center of the top of the sealing cover, a stirring shaft fixedly connected to the output end of the drive motor, a first stirring rod and a second stirring rod fixedly connected to both sides of the stirring shaft, a third stirring rod fixedly connected to the bottom end of the stirring shaft, a weighing box fixedly connected to the right side of the top of the sealing cover, a feeding hopper fixedly connected to the top of the weighing box, a discharge pipe fixedly connected to the bottom end of the batching tank, and a PLC controller fixedly installed at the front end of the jacket.
[0007] As a further technical solution of this utility model, the inlet and outlet water pipes are fixedly connected to the cooling water pipes, and an insulation layer is fixedly connected to the outer side of the jacket.

[0009] As a further technical solution of this utility model, a first solenoid valve is installed on the output pipe of the feeding hopper, and a second solenoid valve is installed on the output pipe of the weighing box.
[0010] As a further technical solution of this utility model, the output pipe of the feeding hopper is fixedly connected to the weighing box, the output pipe of the weighing box is connected through the sealing cover, and a weighing sensor is installed inside the weighing box.
[0011] As a further technical solution of this utility model, the second stirring rod is disposed below the first stirring rod, and the bottom end of the third stirring rod is attached to the bottom end of the inner wall of the mixing tank.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the batching device for titanium dioxide mineral powder raw materials not only realizes the function of easy local temperature control and easy batch feeding, but also realizes the function of avoiding sedimentation and accumulation.
[0013] (1) By setting up a mixing tank, jacket, cooling water pipe, temperature sensor, insulation layer and PLC controller, when the material reacts and mixes inside the mixing tank, the temperature sensor can detect the temperature of the mixing tank in sections. Once the temperature of the corresponding section is detected to be too high, cold water can be injected into the cooling water pipe of the corresponding section to cool it down. The jacket is divided into five independent cooling water pipes to cool down, which can avoid local overheating during the reaction process. This structure realizes the function of enhancing reaction stability and improving product quality.
[0014] (2) By setting up a feeding hopper, a weighing box, a first solenoid valve and a second solenoid valve, iron filings are one of the production raw materials. If all of them are added, it is easy to cause instantaneous concentrated heat release. Therefore, during production, the iron filings can be put into the inside of the feeding hopper and added to the mixing tank in batches. When adding materials, the first solenoid valve is opened first, and the iron filings enter the inside of the weighing box. After the weighing box obtains a certain weight range of iron filings, the first solenoid valve is closed and the second solenoid valve is opened to discharge a certain amount of iron filings into the mixing tank. This structure realizes the functions of convenient batch feeding and quantitative feeding, and improves the stability and safety of the mixing.
[0015] (3) By setting up a stirring shaft, a first stirring rod, a second stirring rod and a third stirring rod, after the raw materials for producing titanium dioxide enter the inside of the mixing tank, the drive motor drives the stirring shaft to rotate at a uniform speed to mix the materials. The first and second stirring rods outside the stirring shaft can enhance the mixing efficiency. The bottom of the third stirring rod contacts the bottom of the inside of the mixing tank, which can prevent the materials from accumulating at the bottom and overheating and the mixing unevenly. This structure realizes the function of avoiding sedimentation and accumulation and improving the mixing ratio efficiency. Attached Figure Description

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.
[0022] Please see Figure 1-4 An embodiment of this utility model provides a batching device for titanium dioxide mineral powder raw materials, including a batching tank 1, a jacket 2 fixedly installed on the outside of the batching tank 1, five sets of cooling water pipes 3 fixedly connected inside the jacket 2, an inlet and outlet water pipe 16 fixedly connected on the left side of the jacket 2, a temperature sensor 4 fixedly connected inside the jacket 2, a sealing cover 6 detachably installed on the top of the batching tank 1, a feeding port 7 fixedly connected on the left side of the top of the sealing cover 6, a drive motor 8 fixedly installed at the center of the top of the sealing cover 6, a stirring shaft 5 fixedly connected to the output end of the drive motor 8, a first stirring rod 11 and a second stirring rod 12 fixedly connected to both sides of the stirring shaft 5, a third stirring rod 13 fixedly connected to the bottom end of the stirring shaft 5, a weighing box 10 fixedly connected to the right side of the top of the sealing cover 6, a feeding hopper 9 fixedly connected to the top of the weighing box 10, a discharge pipe 14 fixedly connected to the bottom end of the batching tank 1, and a PLC controller 15 fixedly installed at the front end of the jacket 2.
[0023] The inlet and outlet water pipes 16 are fixedly connected to the cooling water pipe 3. The outer side of the jacket 2 is fixedly connected to the heat insulation layer 17. The temperature sensor 4 is attached to the outer wall of the mixing tank 1. The temperature sensor 4 is electrically connected to the PLC controller 15.
[0024] Specifically, such as Figure 1 and Figure 2 As shown, when the materials react and mix inside the mixing tank 1, the temperature sensor 4 can detect the temperature of the mixing tank 1 in segments. Once the temperature of the corresponding segment is detected to be too high, cold water can be injected into the cooling water pipe 3 of the corresponding segment to cool it down. The jacket 2 is divided into five independent cooling water pipes 3 to cool down, which can avoid local overheating during the reaction process.
[0025] A first solenoid valve 18 is installed on the output pipe of the feeding hopper 9, and a second solenoid valve 19 is installed on the output pipe of the weighing box 10. The output pipe of the feeding hopper 9 is fixedly connected to the weighing box 10, and the output pipe of the weighing box 10 is connected through the sealing cover 6. A weighing sensor is installed inside the weighing box 10.
[0026] Specifically, such as Figure 1 and Figure 4 As shown, during production, iron filings can be placed into the feeding hopper 9 and added to the mixing tank 1 in batches. When adding materials, the first solenoid valve 18 is opened first, and the iron filings enter the weighing box 10. After the weighing box 10 obtains iron filings within a certain weight range, the first solenoid valve 18 is closed, and the second solenoid valve 19 is opened to discharge a fixed amount of iron filings into the mixing tank 1, thus realizing the functions of convenient batch feeding and fixed quantity feeding.
[0027] The second stirring rod 12 is located below the first stirring rod 11, and the bottom end of the third stirring rod 13 is attached to the bottom end of the inner wall of the mixing tank 1.
[0028] Specifically, such as Figure 1 and Figure 3 As shown, during production and mixing, the drive motor 8 drives the stirring shaft 5 to rotate at a constant speed to mix the materials. The first stirring rod 11 and the second stirring rod 12 outside the stirring shaft 5 can enhance the mixing efficiency. The bottom of the third stirring rod 13 contacts the bottom of the mixing tank 1, which can prevent the materials from accumulating at the bottom, overheating, and becoming unevenly mixed.
[0029] Working principle: First, the corresponding material is poured into the mixing tank 1 through the feeding port 7. Then, the drive motor 8 is started, which drives the stirring shaft 5 to mix the material. While the material is reacting and mixing inside the mixing tank 1, the temperature sensor 4 can detect the temperature of the mixing tank 1 in sections. Once the temperature of the corresponding section is detected to be too high, cold water can be injected into the cooling water pipe 3 of the corresponding section to cool it down. The jacket 2 is divided into five independent cooling water pipes 3 to cool down the material, which can prevent local overheating during the reaction process. The first stirring rod 11 and the second stirring rod 12 outside the stirring shaft 5 can enhance the mixing efficiency. The bottom of the third stirring rod 13 is in contact with the mixing material. The bottom contact of the inside of tank 1 can prevent the material from accumulating at the bottom and overheating, and from causing uneven mixing. Iron filings are one of the raw materials for production. If all of them are added, there will be a sudden concentrated heat release. Therefore, during production, the iron filings can be put into the inside of the feeding hopper 9 and added to the mixing tank 1 in batches. When adding materials, the first solenoid valve 18 is opened first, and the iron filings enter the inside of the weighing box 10. After the weighing box 10 obtains a certain weight range of iron filings, the first solenoid valve 18 is closed, and the second solenoid valve 19 is opened to discharge a certain amount of iron filings into the inside of the mixing tank 1. This structure realizes the functions of convenient batch feeding and quantitative feeding, and improves the stability and safety of the mixing.
