Description

Technical Field

[0001] This utility model relates to the technical field of high-titanium slag processing, specifically a crushing and screening mechanism for high-titanium slag post-processing. Background Technology

[0002] High-titanium slag is a common name for titanium ore enrichment formed through a chemical reaction process. Titanium ore is melted in an electric furnace, and titanium concentrate is smelted in the same furnace. The titanium oxides in the concentrate react chemically with reducing agents (coke, anthracite, semi-coke) to produce TiO2. Due to differences in specific gravity, the slag and iron separate, resulting in titanium-rich material (titanium slag). High-titanium slag is neither waste nor a byproduct; it is the raw material for titanium tetrachloride. High-titanium slag requires crushing, grinding, and grading processes to produce products with qualified particle sizes.

[0003] Currently, there are two main methods for crushing titanium slag. One is primary crushing (mechanical or ball milling) + jaw crusher + hammer crusher. The particle size is mainly controlled by adjusting the rotation speed, discharge port spacing, and the distance between the hammer and the impact plate. However, the control accuracy is poor and the particle size fluctuates greatly with mechanical wear. The second method is primary crushing (mechanical or ball milling) + jaw crusher + ball mill. The discharge particle size is controlled by adjusting the ball mill rotation speed, filling rate, and the ratio of large and small balls. The disadvantage of this method is that the content of fine particles (-200 mesh) is unstable and the particle size fluctuates greatly with mechanical wear. In other words, fine titanium slag is easily crushed repeatedly into fine particles that do not meet the requirements, resulting in resource waste. Utility Model Content

[0004] To address the aforementioned problems, specifically those raised in the background section, this utility model proposes a crushing and screening mechanism for high-titanium slag post-processing. The mechanism includes a base, with symmetrical L-shaped plates fixedly connected to the upper side of the base. A pair of horizontal plates of the L-shaped plates are respectively fixedly connected to one side of a circular box on opposite sides. A feed pipe is fixedly connected to the upper side of the circular box, and a discharge pipe is fixedly connected to the lower side of the circular box. The feed pipe is an inverted trapezoidal feed pipe, with corresponding grooves on its two inclined sides. A pair of symmetrical ear plates are provided at the angle between the two inclined sides of the feed pipe and the circular box, with the outer sides of the two ear plates flush with one side of the circular box. A driving structure is installed on the outer sides of the circular box and the two ear plates. A crushing and screening structure is installed inside the circular box and the feed pipe.

[0005] The drive structure includes a motor, a shaft, a drive wheel, and two pairs of driven wheels;

[0006] The motor is mounted at the other end of the circular box. The two ends of the circular box are respectively bearing connected to one end of the shaft. The output end of the motor is fixedly connected to one end of the shaft. The other end of the shaft passes through the circular box and is fixedly connected to the driving wheel. The driving wheel meshes with two driven wheels. The two pairs of driven wheels are respectively bearing connected to the outer side of one of the corresponding ear plates. The pair of driven wheels on the same side mesh with each other.

[0007] A further feature of this invention is that the crushing and screening structure includes a pair of rotating rods, a pair of swing rods, a pair of crushing plates, an arc-shaped screen plate, and a set of crushing rods.

[0008] The circular box is fixedly connected to the bottom of the arc-shaped screen plate. The central shafts of the two driven wheels at the top are connected to and pass through the corresponding pair of ear plates. The central shafts of the two driven wheels at the top are respectively fixedly connected to the corresponding rotating rods. The other ends of the pair of rotating rods are respectively movably connected to the corresponding swing rods. The other ends of the pair of swing rods pass through the corresponding sliding grooves and are movably connected to the corresponding crushing plates. The pair of crushing plates are located inside the feed pipe. The bottom bearings of the pair of crushing plates are connected to the bottom of the feed pipe. There is a gap at the bottom of the pair of crushing plates. A set of evenly arranged crushing rods are fixedly connected to the outside of the shaft.

[0009] A further feature of this invention is that each of the crushing rods is composed of a support rod and a crushing blade.

[0010] A further feature of this invention is that the arc-shaped sieve plate matches the bottom of the circular box.

[0011] A further feature of this invention is that the driving wheel and the two pairs of driven wheels are provided with dustproof shells on their outer sides.

[0012] A further feature of this invention is that the shaft and the circular box are concentric.

[0013] A further feature of this invention is that the pair of crushing plates are arranged in an inverted trapezoidal shape, and the outer sides of the pair of crushing plates are attached to the inner wall of the feed pipe.

[0014] The beneficial technical effects of this utility model are as follows: This utility model first breaks high-titanium slag into small particles through the reciprocating swing of a pair of crushing plates. The small particles fall into a circular box and are located on the upper side of the arc-shaped screen plate. The small particles in the circular box are further crushed by a set of crushing blades to break them into fine particles. Under the action of the arc-shaped screen plate, unqualified particles are screened out. Qualified fine particles fall out through the screen holes of the arc-shaped screen plate, while unqualified fine particles continue to be crushed on the arc-shaped screen plate, which improves the screening efficiency and ensures the output of qualified particle size products.

Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0022] This utility model proposes a crushing and screening mechanism for the post-processing of high-titanium slag. When using this device, the motor 5 is started, driving the shaft to rotate. The shaft drives a set of crushing rods 11 to rotate. A gap is left between the lower crushing rod 11 and the arc-shaped screen plate 12. The shaft drives the drive wheel 9 to rotate, which in turn drives two driven wheels 8 meshing with it. These two driven wheels 8 then drive two other driven wheels 8 meshing with them to rotate. These two driven wheels 8 then drive corresponding rotating rods 10 to rotate. A pair of rotating rods 10 drives corresponding swing rods 3 to reciprocate along corresponding chute 7. The pair of swing rods 3 then drive corresponding crushing plates 2... The feed pipe 1 reciprocates, pouring high-titanium slag into the device (located between a pair of crushing plates 2). The pair of crushing plates 2 reciprocate, crushing the high-titanium slag into small particles. The small particles fall into the circular box 4 and onto the arc-shaped screen plate 12. A set of crushing rods 11 rotates to perform secondary crushing on the small particles, breaking them into fine particles. Under the action of the screen holes of the arc-shaped screen plate 12, unqualified particles can be screened. Qualified fine particles fall out through the screen holes of the arc-shaped screen plate 12, while unqualified fine particles continue to be crushed on the arc-shaped screen plate 12, improving screening efficiency and ensuring the output of qualified particle size products.
