[0002] The main components of red mud include aluminum oxide (Al2O3), iron oxide (Fe2O3), silicon dioxide (SiO2) and calcium oxide (CaO), which account for more than 60% of the total red mud. Red mud also contains a certain amount of other elements, such as sodium oxide (Na2O) and titanium oxide (Ti2O). Because it contains a large amount of iron oxide and its appearance is similar to red soil, it is called red mud.

[0003] Magnetic separation is a technology for extracting ferroferric oxide and ferrite magnets from red mud. This technology first separates ferroferric oxide and ferrite magnets in the reductive conversion slurry through magnetic separation, and then washes and purifies them to obtain iron concentrate with an iron content of up to 70.31%. This iron concentrate can not only be used as a raw material for ironmaking, but can also be used to further extract valuable metals and iron from red mud, achieving efficient resource utilization.

[0004] Before processing red mud, it must first be filtered to remove water, then crushed and dried, and finally dried and finely ground to ensure that its size is less than 0.5CM, so that it can be easily combined with other mixed materials. However, when processing the material, the existing device is not convenient for building a long drying channel due to limited space, resulting in low drying efficiency for the material. In addition, the existing rolling device and drying device generally process the material in a quantitative manner, cannot provide fluidity to the material, and are relatively inefficient. Therefore, improvements are made to the existing device to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In this utility model:

[0025] Reference Figure 1-6 ,

[0026] Embodiment 1: A mobile fine grinding device with a drying function includes a device body 1 and a feed port 101. The feed port 101 is integrally provided above the device body 1. An exhaust port 102 is integrally provided above the device body 1 near the feed port 101. A filter screen 1021 is movably connected to the exhaust port 102. An exhaust fan 2 is connected above the exhaust port 102. The exhaust fan 2 can discharge the gas generated inside the device. At the same time, the filter screen 1021 can be filtered and can also be replaced. A discharge valve 9 is installed at the discharge port at the bottom of the device body 1 to ensure that the material is evenly and smoothly delivered. A drying component that can dry the material body is provided inside the device body 1;

[0027] The drying assembly includes: a guide plate 3, an arc-shaped groove 301, a heating wire 302, a stirring shaft 4, a scraper 401, and a rake 402. The guide plate 3 is installed inside the device body 1, and an arc-shaped groove 301 is integrated inside the guide plate 3. A heating wire 302 is installed in the interlayer between the arc-shaped groove 301 and the guide plate 3. A stirring shaft 4 is provided through the device body 1, and scrapers 401 and rakes 402 are symmetrically installed on the side of the stirring shaft 4; the number of drying assemblies is at least three groups, and each guide plate 3 has at least three arc-shaped grooves 301 inside. The heating wire 302 heats the arc-shaped groove 301 to dry the material, and the motor drives the stirring shaft 4 to rotate. At this time, the scraper 401 and the rake 402 rotate synchronously. At this time, part of the material can be shoveled and turned over, and the scraper 401 can scrape a layer of material near the bottom of the arc-shaped groove 301 into the next arc-shaped groove 301. This design extends the drying path of the material and increases the drying efficiency of the device.

[0028] A dispersion tank 5 is integrated in the middle of the internal part of the device body 1, and a double-axis reducer 501 is installed inside the dispersion tank 5. The upper output end of the double-axis reducer 501 is connected to a homogenizing plate 6, and the lower output end of the double-axis reducer 501 is connected to a linkage shaft 8. The linkage shaft 8 is divided into two, one end is rotatably connected to a pressure roller 801, and the other end is installed with a steel brush plate 802. The scraper 401 and the rake plate 402 extend to the inside of the screening tank 7, and the diameter of the sieve hole at the bottom of the screening tank 7 is 0.5CM. The linkage shaft 8 rotates, so that the pressure roller 801 crushes and crushes the material inside the screening tank 7, and the rotating steel brush plate 802 can sweep the crushed material out of the sieve hole. At the same time, the steel brush bristles are elastic, which can avoid clogging of the sieve hole.

[0029] Inside the device body 1, an annular support frame 1031 is slidably connected to the bottom of the dispersion tank 5 through the slide groove 103. A spring 105 is provided between the device body 1 and the lower edge of the annular support frame 1031. The device body 1 is located at the lower edge of the annular support frame 1031 and is rotatably connected to the eccentric wheel 104. The eccentric wheel 104 impacts the annular support frame 1031, which indirectly moves the screening tank 7 up and down, causing the screening tank 7 to shake. Cooperating with the linkage shaft 8, the crushing of the material can be strengthened to improve efficiency.

[0030] The inside of the annular support frame 1031 is connected to the screening slot 7 through a turntable rotation. A driving motor 1032 is installed on the inner wall of the annular support frame 1031. A driving gear 1033 is installed on the output shaft of the driving motor 1032. The outer wall of the screening slot 7 is provided with an array of teeth, and the teeth are engaged with the driving gear 1033. The driving motor 1032 drives the driving gear 1033 to rotate, and then the teeth of the driving gear 1033 are engaged to make the screening slot 7 and the linkage shaft 8 rotate in opposite directions. This design can make the efficiency of the entire device higher.

[0031] Furthermore, a roller is rotatably connected to the end of the eccentric wheel 104, and the eccentric wheel 104 acts between the roller and the upper edge of the screening slot 7. This design can reduce friction.

[0032] Furthermore, the surface of the homogenizing plate 6 is provided with protrusions, and the rotating homogenizing plate 6 can break up the material by utilizing the protrusions on its surface. At this time, the material evenly passes through the dispersion tank 5 and enters the screening tank 7.

[0033] Furthermore, a motor is installed outside the device body 1, and the output shaft of the motor is connected to the stirring shaft 4 and the input shaft of the dual-axis reducer 501, and the motor, discharge valve 9, drive motor 1032, and exhaust fan 2 are all electrically connected to the external power supply.

[0034] Working principle: First, the material is introduced from the feed port 101. At this time, the material enters the interior of the arc groove 301. The heating wire 302 heats the arc groove 301 to dry the material, and the motor drives the stirring shaft 4 to rotate. At this time, the scraper 401 and the rake plate 402 rotate synchronously. At this time, part of the material can be shoveled and turned over, and the scraper 401 can scrape a layer of material near the bottom of the arc groove 301 into the next arc groove 301. This design extends the drying path of the material and increases the drying efficiency of the device. Then, the material enters the dispersion tank 5. At this time, the motor inputs power to drive the output shaft of the dual-axis reducer 501 to rotate. The rotating homogenizing plate 6 can use the protrusions on its surface to break up the material. At this time, the material passes through the dispersion tank 5 evenly. When entering the screening trough 7, the linkage shaft 8 rotates, causing the pressure roller 801 to crush the material inside the screening trough 7, and the rotating steel brush plate 802 can sweep the crushed material out of the sieve hole. At the same time, the steel brush bristles are elastic and can avoid clogging of the sieve hole. At the same time, the driving motor 1032 is controlled to drive the driving gear 1033 to rotate, and then the driving gear 1033 is used to engage the teeth to make the screening trough 7 and the linkage shaft 8 rotate in opposite directions. This design can make the entire device more efficient. Then, the motor is used to drive the eccentric wheel 104 to rotate, and the eccentric wheel 104 impacts the annular support frame 1031, which can indirectly move the screening trough 7 up and down, causing the screening trough 7 to shake, and cooperate with the linkage shaft 8 to enhance the crushing of the material and improve efficiency.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
