Technical Field

[0001] The utility model relates to the technical field of iron removal, in particular to a kaolin iron removal device. Background Art

[0002] Kaolin is an important non-metallic mineral with fine texture and white color. It is also called dolomite and is widely used. Since kaolin contains an indefinite amount of iron tetroxide, iron trioxide and iron-containing silicates, which will affect the color of the product, there are special requirements for its iron content. For example, industrial kaolin requires that the iron trioxide content is less than 0.5%, and kaolin needs to be treated for iron removal. In the prior art, kaolin is made into slurry and then iron is removed by an iron removal device. The existing iron removal device achieves the purpose of iron removal by setting a magnetic plate at the bottom of the conveyor belt. However, after long-term operation, the clay in the kaolin will adhere to the conveyor belt, reducing the magnetism of the magnetic plate, affecting the iron removal effect and the quality of the slurry. Utility Model Content

[0003] The utility model aims to design a kaolin iron removal device, so that clay in kaolin will not adhere to the conveyor belt during the iron removal process, affecting the iron removal effect and the quality of the slurry, so as to solve the problems raised in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kaolin iron removal device is provided, comprising a frame, on which an iron removal component and a cleaning component are installed, the iron removal component comprises a first transmission roller, a second transmission roller and a third transmission roller, the first transmission roller, the second transmission roller and the third transmission roller are connected by a conveyor belt, the first transmission roller is higher than the second transmission roller and the third transmission roller, the second transmission roller is higher than the third transmission roller, and a magnetic plate is installed at the lower end of the upper part of the conveyor belt on the frame; the cleaning component comprises a scraper and a nozzle, one end of the scraper is installed on the frame, the other end of the scraper directly contacts the lower part of the conveyor belt, the nozzle is located below the scraper, one end of the nozzle is connected to a water distribution pipe, and the other end of the nozzle directly contacts the lower part of the conveyor belt; the water distribution pipe is connected to a water inlet pipe, and the water inlet pipe is connected to a water storage tank; a storage trough and a waste trough are provided directly below the conveyor belt, and the waste trough is located directly below the cleaning component.

[0005] Furthermore, a receiving platform is provided on the upper portion of the inner wall of the waste trough, and a filter plate is placed on the receiving platform.

[0006] Furthermore, the waste tank is connected to the water storage tank through a waste liquid pipe, and the waste liquid pipe is located below the filter plate.

[0007] Furthermore, a first pump body is installed on the water inlet pipe.

[0008] Furthermore, the material storage tank is connected to a material conveying pipe, and a second pump body is installed on the material conveying pipe.

[0009] Furthermore, a feeding funnel is installed on the frame above the conveyor belt.

[0010] Furthermore, the discharge port of the feed hopper is arc-shaped.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] When the utility model is in use, by arranging the iron removal component and the cleaning component, the slurry flows to the conveyor belt close to the first transmission roller. Since the first transmission roller is higher than the second transmission roller, the conveyor belt is inclined along the direction of the second transmission roller. Under the gravity of the slurry itself, the slurry flows from the conveyor belt on the first transmission roller through the conveyor belt on the magnetic plate to the conveyor belt on the second transmission roller, thereby achieving the iron removal effect. The slurry after iron removal directly flows to the storage tank for storage. At the same time, the conveyor belt is driven in the direction opposite to the flow direction of the slurry. The speed of the conveyor belt rotation is much smaller than the flow rate of the slurry. The position where the slurry flows is first scraped by the scraper to scrape off the clay and iron filings remaining on the conveyor belt. Then, the water from the water storage tank passes through the water inlet pipe and the water distribution pipe, and the conveyor belt is cleaned by the nozzle. The residual clay, iron filings and waste water generated by cleaning flow into the waste tank, thereby achieving that the clay in the kaolin will not adhere to the conveyor belt during the iron removal process, thereby reducing the magnetism of the magnetic plate, affecting the iron removal effect and the quality of the slurry.

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] Example: Please refer to Figure 1-2A kaolin iron removal device comprises a frame 1, on which an iron removal component and a cleaning component are installed, the iron removal component comprises a first transmission roller 2, a second transmission roller 3 and a third transmission roller 4, the first transmission roller 2, the second transmission roller 3 and the third transmission roller 4 are connected by a conveyor belt 5, the first transmission roller 2 is higher than the second transmission roller 3 and the third transmission roller 4, so that the conveyor belt 5 is inclined along the direction of the second transmission roller 3, the second transmission roller 3 is higher than the third transmission roller 4, and the cross-section of the combination of the first transmission roller 2, the second transmission roller 3, the third transmission roller 4 and the conveyor belt 5 is a triangle; a magnetic plate 6 is installed at the lower end of the upper part of the conveyor belt 5 on the frame 1; a storage trough 12 is provided directly below the conveyor belt 5, and a waste trough 13 is located directly below the second transmission roller 3. A feed hopper 20 is installed on the frame 1 above the conveyor belt 5. The discharge port 21 of the feed hopper 20 is arc-shaped and is located above the conveyor belt 5 between the magnetic plate 6 and the first drive roller 2, which can slow down the discharge speed of the slurry, reduce the impact force on the conveyor belt 5, and reduce the flow rate of the slurry on the conveyor belt 5, so that the slurry can be fully deironed. The slurry flows to the conveyor belt 5 close to the first drive roller 2. Since the first drive roller 2 is higher than the second drive roller 3, the conveyor belt 5 is inclined in the direction of the second drive roller 3. Under the gravity of the slurry itself, the slurry flows from the conveyor belt 5 on the first drive roller 2 through the conveyor belt 5 on the magnetic plate 6 to the conveyor belt 5 on the second drive roller 3, thereby achieving the deironing effect. The deironed slurry directly flows to the storage tank 12 for storage. The material storage tank 12 is connected to a material conveying pipe 18, and a second pump body 19 is installed on the material conveying pipe 18. The second pump body 19 is a water pump. When the slurry in the material storage tank 12 reaches a certain height, the second pump body 19 is started to convey the slurry in the material storage tank 12 to the next process through the material conveying pipe 18. A first baffle 22 and a second baffle 23 are installed on both sides of the frame 1. The first baffle 22 and the second baffle 23 are connected by a third baffle 24. The third baffle 24 is located directly above the conveyor belt 5. The first baffle 22, the second baffle 23 and the third baffle 24 are used to prevent the slurry from splashing out and polluting the environment.

[0021] The cleaning assembly includes a scraper 7 and a nozzle 8. One end of the scraper 7 is mounted on the frame 1, and the other end of the scraper 7 directly reaches the lower part of the conveyor belt 5. The nozzle 8 is located below the scraper 7. One end of the nozzle 8 is connected to the water distribution pipe 9, and the other end of the nozzle 8 directly reaches the lower part of the conveyor belt 5. The water distribution pipe 9 is connected to the water inlet pipe 10, and the water inlet pipe 10 is connected to the water storage tank 11. The first pump body 17 is installed on the water inlet pipe 10. The first pump body 17 is a booster pump, so that the water sprayed by the nozzle 8 has a certain pressure to clean the conveyor belt 5. A waste trough 13 is provided directly below the conveyor belt 5. The waste trough 13 is located directly below the cleaning assembly. A receiving platform 14 is provided on the upper part of the inner wall of the waste trough 13. A filter plate 15 is placed on the receiving platform 14 for filtering clay and iron filings. The waste trough 13 is connected to the water storage tank 11 through a waste liquid pipe 16, and the waste liquid pipe 16 is located below the filter plate 15. Under the action of its own gravity, the slurry is deironed through the conveyor belt 5 on the magnetic plate 6. At the same time, the conveyor belt 5 is driven in the direction opposite to the flow direction of the slurry. The rotation speed of the conveyor belt 5 is much smaller than the flow rate of the slurry. The position where the slurry flows first passes through the scraper 7 to scrape off the residual clay on the conveyor belt 5, and then the water from the water tank 11 passes through the water inlet pipe 10 and the water distribution pipe 9, and the conveyor belt 5 is cleaned by the nozzle 8. The residual clay, iron filings and waste water generated by cleaning flow into the filter plate 15 in the waste tank 13 for filtration. The filtered water flows into the water tank 11 through the waste liquid pipe 16 for recycling, thereby reducing water waste. In this way, the clay in the kaolin will not adhere to the conveyor belt 5 during the deironing process, thereby reducing the magnetism of the magnetic plate 6 and affecting the deironing effect and the quality of the slurry.

[0022] The working principle of this embodiment is as follows: the slurry from the feed hopper 20 flows to the conveyor belt 5 near the first transmission roller 2. Since the first transmission roller 2 is higher than the second transmission roller 3, the conveyor belt 5 is inclined along the direction of the second transmission roller 3 and has a certain slope to ensure that the slurry will not be affected by the conveying power of the conveyor belt 5. Under the gravity of the slurry itself, the slurry flows from the conveyor belt 5 on the first transmission roller 2 through the conveyor belt 5 on the magnetic plate 6 to the conveyor belt 5 on the second transmission roller 3 to remove iron. After iron removal, the slurry directly flows to the storage tank 12 for storage. When the slurry in the storage tank 12 reaches a certain height, the second pump body 1 9 is started, and the slurry in the storage tank 12 is transported to the next process through the material conveying pipe 18; at the same time, the conveyor belt 5 is driven in the direction opposite to the flow direction of the slurry, and the rotation speed of the conveyor belt 5 is much lower than the flow rate of the slurry. The position where the slurry flows first passes through the scraper 7 to scrape off the clay and iron filings remaining on the conveyor belt 5, and then the water from the water storage tank 11 passes through the water inlet pipe 10 and the water distribution pipe 9, and the conveyor belt 5 is cleaned by the nozzle 8. The remaining clay, iron filings and waste water generated by cleaning flow into the filter plate 15 in the waste tank 13 for filtration, and the filtered water flows into the water storage tank 11 through the waste liquid pipe 16 for recycling, and the operation is like this.
