Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and more specifically, to a cement slag removal device for cement production. Background Technology

[0002] Cement grinding is the final and most energy-intensive step in cement production. Its main function is to grind cement clinker (along with retarders and performance modifiers) to a suitable particle size (expressed as fineness, specific surface area, etc.), forming a specific particle size distribution, increasing its hydration surface area, accelerating the hydration rate, and ensuring the cement paste sets. The grinding media used are typically low-chromium spherical forgings. With prolonged use, these media gradually shrink, and may even break. The resulting iron slag enters the finished cement silo along with the cement, making iron slag a major problem in cement packaging.

[0003] Traditional cement slag removal devices typically use magnets to remove iron slag from cement powder. However, most existing slag removal devices have their magnets located inside the device, making it difficult to clean the iron slag off the magnets later.

[0004] Furthermore, after the cement powder is crushed, due to the incomplete crushing process, a small amount of large cement slag will still appear inside. Traditional slag removal devices cannot screen out this cement slag, which can easily cause blockage during subsequent discharge. Utility Model Content

[0030] Please see Figure 1-5A cement slag removal device for cement production includes a shell 1. A slag removal barrel 2 is movably mounted inside the shell 1. A square block 3 is fixed to the outer wall of the slag removal barrel 2. Guide rods 4 are fixed to both sides of the square block 3 and are slidably installed with the shell 1. An L-shaped rod 5 is fixed to the upper part of the outer wall of the shell 1. A movable block 6 is movably mounted at the upper end of the L-shaped rod 5. Sliding rods 7 are located at the bottom of the movable block 6 and at each of its four corners, and are slidably installed with the L-shaped rod 5. An electric push rod 8 is fixed to the lower end of the L-shaped rod 5. The output end of the electric push rod 8 is fixedly connected to the movable block 6. A first motor 9 is fixed to the upper end of the movable block 6. A rotating shaft 10 is located at the output end of the first motor 9. Magnetic rods 11 are arranged on the outer wall of the rotating shaft 10, and multiple magnetic rods 11 are evenly distributed. The rotating shaft 10 is movably installed with the L-shaped rod 5. A screening mechanism is provided inside the slag removal barrel 2.

[0031] In this embodiment, the screening mechanism includes a screening mesh 12, which is slidably installed on the inner wall of the slag removal bucket 2. A pull rod 13 is fixedly provided on the upper end face of the screening mesh 12 and on both sides. A connecting block 14 is fixedly provided on the upper end face of the pull rod 13. The connecting block 14 is in contact with the upper end face of the slag removal bucket 2. Ear plates 15 are provided on the outer wall of the slag removal bucket 2 and on both sides. A threaded post 16 is provided on the ear plate 15. The connecting block 14 is movably installed with the threaded post 16. A fastening nut 17 is provided on the threaded post 16. A guide rod 4 on one side passes through the housing 1 and is fixedly provided with a contact block 18. A second motor 19 is fixedly provided on one side of the housing 1.

[0032] More specifically, the user can control the electric push rod 8 to lower the moving block 6 and the magnetic rod 11 until it enters the slag removal bucket 2. Then, the cement powder is poured into the slag removal bucket 2, and the first motor 9 is controlled to slowly rotate the magnetic rod 11 to agitate the cement powder, thereby adsorbing the iron slag inside onto the magnetic rod 11 to achieve the slag removal effect. Then, the electric push rod 8 is controlled to raise the moving block 6 to remove the magnetic rod 11 from the slag removal bucket 2, which helps to clean the iron slag on the magnetic rod 11 laterally. After the magnetic rod 11 is removed from the slag removal bucket 2, the user can control the second motor 19 to make the cam 20 drive the contact block 18 and the screen 12 to swing left and right, so that the cement powder inside the slag removal bucket 2 swings left and right, so that the cement powder of the specified size falls quickly through the screen 12, while the large cement slag particles are left at the top of the screen 12. The screen 12 can be disassembled by removing the fastening nut 17 to facilitate the collection of the cement slag at the top, which is helpful for secondary processing.

[0033] Please see Figure 1 and Figure 4 As an implementation method for adjusting the tilt angle of the discharge hopper 23: a partition 21 is fixedly provided on the inner wall of the shell 1 at the lower end, a hose 22 is fixedly provided at the bottom of the slag removal bucket 2, and the other end of the hose 22 is fixedly connected to the partition 21. The discharge hopper 23 is rotatably provided at the lower end of the partition 21 and inside the shell 1. A locking pin 24 is fixedly provided on one side of the discharge hopper 23, and an arc-shaped hole 25 is correspondingly opened on one side of the shell 1. The locking pin 24 is located inside the arc-shaped hole 25, and a locking nut 26 is provided on the locking pin 24. The locking nut 26 is threadedly connected to the locking pin 24.

[0034] Specifically, the cement powder leaking from the bottom of the hose 22 will enter the discharge hopper 23 and leave the housing 1 through the guide of the discharge hopper 23. At this time, the user can place the receiving device at one end of the discharge hopper 23 for easy receiving. The user can also adjust the tilt angle of the discharge hopper 23 by removing the fastening nut 17 to facilitate connection with receiving devices of different heights, increasing the flexibility of the device during use.

[0035] Please refer to Figure 1 As a further embodiment for guiding cement powder: one end of the discharge hopper 23 is open, and the discharge hopper 23 is located directly below the hose 22.

[0036] Specifically, by setting up the discharge hopper 23, cement powder can be guided to facilitate subsequent connection with other receiving equipment and make it convenient to use.

[0037] In summary, during operation, the user can control the electric push rod 8 to lower the moving block 6 and the magnetic rod 11 until it enters the slag removal tank 2. Cement powder is then poured into the slag removal tank 2, and the first motor 9 is controlled to slowly rotate the magnetic rod 11 to agitate the cement powder, thereby attracting the iron slag inside to the magnetic rod 11, achieving the slag removal effect. The electric push rod 8 is then controlled to raise the moving block 6, removing the magnetic rod 11 from the slag removal tank 2, facilitating subsequent cleaning of the iron slag on the magnetic rod 11. After the magnetic rod 11 is removed from the slag removal tank 2, the user can control the second motor 19 to cause the cam 20 to move the contact block 18 and the screening screen 12 left and right, thus cleaning the contents of the slag removal tank 2. The cement powder is shaken from side to side, causing cement powder of the specified size to fall quickly through the screening screen 12, while large cement slag particles remain at the top of the screening screen 12. The screening screen 12 can be disassembled by removing the fastening nut 17 to facilitate the collection of cement slag at the top, which is helpful for secondary processing. The cement powder leaking from the bottom of the screening screen 12 will enter the discharge hopper 23 through the hose 22 and leave the housing 1 through the guide. At this time, the user can place the receiving device at one end of the discharge hopper 23 for easy receiving. The tilt angle of the discharge hopper 23 can also be adjusted by removing the fastening nut 17 to facilitate connection with receiving devices of different heights, increasing the flexibility of the device during use.

[0038] The first motor mentioned above is controlled by a controller or driver. Since the controller and matching equipment are common devices and belong to existing mature technologies, their electrical connection relationship and specific circuit structure will not be described in detail here.
