Description

Technical Field

[0001] The utility model relates to the field of titanium material production, in particular to an acid-base neutralization reaction device for titanium materials. Background Art

[0002] Titanium-based materials are important inorganic chemical pigments whose main component is titanium dioxide. Titanium-based materials have stable chemical properties and generally do not react with most substances. They have important applications in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, ceramics, lithium extraction from salt lake brines, and lithium battery recycling. Acid-base neutralization primarily involves reacting solid metatitanic acid with alkaline solution to produce sodium metatitanate, a key intermediate in the industrial production of titanium-based materials. The quality of acid-base neutralization directly impacts subsequent processes and the final quality of the titanium-based materials. Traditional production-based acid-based neutralization reaction equipment is relatively simple, primarily using an alkaline reactor as the reaction unit. During stirring, the neutralization of metatitanic acid and alkali can easily cause splashing, which can cause personal injury. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 Schematic diagram of the front view of the reaction device. DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] An acid-base neutralization reaction device for titanium materials, such as Figure 1As shown, the reactor 1 includes two baffles 2, a gripping end 31, a connecting rod 32, and a plurality of stirring blades 33. The reactor 1 is cylindrical, rectangular, or square, preferably cylindrical. An inlet 11 is provided at the top of the reactor 1, and a drain port 12 is provided at the bottom of the side wall. The two baffles 2 are arranged opposite each other on the inner wall of the reactor 1. If the reactor 1 is square, the two baffles 2 are arranged on two parallel inner walls. If the reactor 1 is cylindrical, the two baffles 2 are located on the diameter of the cylinder. A flow gap is provided between the two baffles 2 and the inner wall of the reactor 1, allowing water to flow into the flow gap. A plurality of circular holes are evenly distributed on the side walls of the baffles 2, and the circular holes penetrate the baffles 2. The baffles 2 function as a flow disruptor. To prevent material blockage, the circular holes are set to a diameter of 1-2 cm. The circular holes are designed to allow some liquid material to flow in the direction of stirring, while others flow into the gap between baffle 2 and the inner wall of reactor 1, flowing in the direction of stirring. The water will strike the sidewall of baffle 2, causing some of the water to flow back. When circular holes are provided, the water can flow through them, making the flow more stable. This allows the remaining solid material in reactor 1 to be fully dispersed and dissolved, allowing the alkali solution and metatitanic acid to fully react. To reduce the blocking effect of baffle 2, baffle 2 can also be made thinner. The optimal thickness is 0.05-0.1mm, which provides sufficient strength and does not block the water flow.

[0019] The connecting rod 32 is vertically arranged directly above the center of the reactor 1. The upper end of the connecting rod 32 is connected to the gripping end 31, which is a driving device that can rotate the connecting rod 32. The lower end of the connecting rod 32 is located in the reactor 1. A plurality of stirring blades 33 are arranged around the lower end of the connecting rod 32. In order to improve the stirring effect, the stirring blades 33 are evenly distributed around the circumference of the connecting rod 32.

[0020] The stirring blade 33 includes a first wall section 34 and a second wall section 35. The end of the first wall section 34A is connected to the lower end of the connecting rod 32, and the end of the first wall section 34B is connected to the end of the second wall section 35A. An angle is set between the first wall section 34 and the second wall section 35. The direction of the angle is vertically downward, that is, the second wall section 35 is set downward. The connection between the first wall section 34 and the second wall section 35 forms a first turbulence zone. Compared with the commonly used stirring blades, its stirring buffer force can be increased by 40%, and the optimal angle is 60-120. In order to enhance the turbulence effect, a turbulence hole is provided on the second wall section 35. The end of the second wall section 35 is provided with an arc-shaped turbulence hook to form a second turbulence zone. When the stirring device 3 rotates, the vortex between the first turbulence zone and the second turbulence zone forms a buffer zone in the turbulence hole. Through the combination of the first turbulence zone, the second turbulence zone and the buffer zone, the vortex formed when the liquid material rotates can be turbulent to prevent liquid splashing.

[0021] To fully dissolve the solid metatitanic acid and improve the quality of the final product, the first and second wall sections 34, 35 are circumferentially serrated. When the device is operating, the serrated first and second wall sections 34, 35 more quickly and effectively cut and break up the solid metatitanic acid material. Conventional stirring blades are flat, making it difficult to break up smaller solid metatitanic acid materials. This results in an incomplete reaction between the metatitanic acid and the base, leading to quality issues in the final product.

[0022] In order to achieve a better buffering effect, a buffer pad 4 is provided at the bottom of the inner wall of the reactor 1 .

[0023] The working method and principle of the acid-base neutralization reaction device for titanium materials are as follows: solid metatitanate material and alkali solution are placed into the reactor 1 through the inlet 11, and the reaction device is started. At this time, the gripping end 31 rotates rapidly, and the first section wall 34 and the second section wall 35 quickly break up the solid metatitanate material during the rotation process. The metatitanate material reacts fully with the alkali solution to finally form sodium metatitanate, which is discharged through the drain port 12 and enters the next production process.
