DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0028] like Figure 3 As shown, a mixing and heating device for titanium dioxide processing includes: a mixing drum 1, a mixing mechanism 5 arranged in the mixing drum 1, a feeding assembly 4 arranged at the top of the mixing drum 1, and a discharge pipe 3 arranged at the bottom of the mixing drum 1;

[0029] like Figure 1-Figure 2 As shown, the mixing mechanism 5 includes a rotating rod 504, a motor 503 provided at the bottom of the rotating rod 504, a plurality of connecting rods 505 provided on the outer wall of the rotating rod 504, a plurality of scraping rods 508 provided on the inner wall of the mixing barrel 1, and a common connecting ring 509 provided on the top of the plurality of scraping rods 508;

[0030] The motor 503 is fixedly connected to the bottom of the mixing drum 1. One end of the output shaft of the motor 503 passes through the mixing drum 1 and is fixedly connected to the bottom of the rotating rod 504. A plurality of connecting rods 505 are fixedly connected to the circumferential outer wall of the rotating rod 504. A heating device is provided in each of the connecting rods 505. Two symmetrical stirring blades 506 are fixedly connected to the circumferential outer wall of each of the connecting rods 505. One side of each of the scraping rods 508 is fixedly connected to one end of each of the corresponding connecting rods 505.

[0031] The outer walls of several scraper rods 508 fit tightly with the circumferential inner wall of the mixing drum 1, the tops of several scraper rods 508 are fixedly connected to the bottom of the same connecting ring 509, the circumferential outer wall of the rotating rod 504 is fixedly connected to the limiting ring 510, the bottom of the limiting ring 510 is rotatably connected to the bottom inner wall of the mixing drum 1, and several through grooves 507 are opened on one side of the stirring blade 506.

[0032] It should be noted that the motor 503 drives the rotating rod 504 to rotate, thereby driving the connecting rod 505 and the stirring blade 506 thereon to stir efficiently, ensuring that the mixture of ore and concentrated sulfuric acid is fully mixed in the mixing barrel 1, thereby improving the reaction efficiency; the heating device set in the connecting rod 505 can quickly and evenly heat the mixture, promote the reaction of titanium ore and sulfuric acid, thereby accelerating the formation of disodium titanate, helping to avoid local overheating or insufficient reaction problems, and improving the extraction efficiency of titanium; the scraper rod 508 is tightly fitted to the circumferential inner wall of the mixing barrel 1, and moves with the rotation of the rotating rod 504, The scraping rods 508 are fixedly connected by the connecting ring 509 to enhance the stability of the scraping rods 508, so that the scraping rods 508 are more powerful and less prone to damage when scraping the residues; the setting of the limiting ring 510 enables the rotating rod 504 to remain stable during the rotation process, avoiding equipment damage caused by shaking; the through groove 507 opened on the stirring blade 506 helps to reduce the resistance during the stirring process, reduce the energy consumption of the motor 503, and increase the strength and durability of the stirring blade 506.

[0033] like Figure 1-Figure 2 As shown, a protective shell 501 is fixedly connected to the bottom of the mixing drum 1 , a motor 503 is located inside the protective shell 501 , and a plurality of penetrating heat dissipation slots 502 are provided on the circumferential outer wall of the protective shell 501 .

[0034] It should be noted that the protective shell 501 provides a closed and safe operating environment for the motor 503. During the titanium dioxide processing, splashing materials or corrosive gases may be generated inside the mixing barrel 1. The protective shell 501 can effectively isolate these harmful substances, protect the motor 503 from damage, and ensure its long-term stable operation; a number of heat dissipation slots 502 are passed through to provide heat dissipation channels for the motor 503. The motor 503 will generate heat during operation. If the heat is not dissipated in time, it will cause the motor 503 to overheat, affecting its performance and life. The heat dissipation slots 502 can allow air to circulate, effectively taking away the heat generated by the motor 503, and reducing the operating temperature of the motor 503.

[0035] like Figure 1-Figure 3 As shown, the feed assembly 4 includes: a feed pipe 401, the feed pipe 401 passes through the mixing drum 1 and is fixedly connected, a plurality of discharge troughs 402 are provided on the circumferential inner wall of the feed pipe 401, an X-shaped reinforcement rod 403 is fixedly connected to the circumferential inner wall of the feed pipe 401, the bottom pipe of the mixing drum 1 is connected to the outlet pipe 3, the circumferential outer wall of the outlet pipe 3 is provided with a valve, and a plurality of support legs 2 are fixedly connected to the bottom of the mixing drum 1.

[0036] It should be noted that the discharge trough 402 allows the material to enter the mixing drum 1 in a uniform distribution, avoiding the accumulation of material at the feed port or the formation of local high concentration areas, ensuring the uniform distribution of material in the mixing drum 1, which is conducive to subsequent efficient mixing and reaction; the X-shaped reinforcement rod 403 can enhance the structural strength of the feed pipe 401, enabling it to withstand greater material pressure and impact force, thereby improving the durability and stability of the feed component 4; the valve provided on the outlet pipe 3 allows the operator to conveniently control the outflow speed and amount of the material, thereby achieving precise control of the mixing process; a number of support legs 2 can provide stable support for the equipment, ensuring its stability during operation.

[0037] To use the present invention, turn on the power to motor 503, which will drive the rotating rod 504 to begin rotating. At this point, the connecting rod 505 and its stirring blades 506 begin stirring the materials within the mixing drum 1. Simultaneously, the heating device within the connecting rod 505 is activated to heat the mixture, promoting the reaction between the titanium ore and sulfuric acid. The prepared mixture of titanium ore and concentrated sulfuric acid is poured into the mixing drum 1 through the feed pipe 401. Because the inner wall of the feed pipe 401 is provided with several discharge troughs 402 extending therethrough, the materials are evenly distributed within the mixing drum 1, preventing accumulation or the formation of localized areas of high concentration.

[0038] Driven by motor 503, stirring blades 506 continuously stir the mixture, ensuring thorough mixing and reaction within mixing drum 1. Simultaneously, a heating device continues to heat the mixture to accelerate the formation of disodium titanate. Once the mixture reaches the desired mixing quality and reaction level, the heating device is turned off and motor 503 is stopped. The valve on outlet pipe 3 is opened to allow the mixed material to exit mixing drum 1.

[0039] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel 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 content of the specification, but must be determined according to the scope of the claims.
