Description

Technical Field

[0001] This utility model relates to the field of iron concentrate processing technology, and in particular to a screening and impurity removal device for iron concentrate processing. Background Technology

[0002] In steel production, the quality of iron concentrate plays a crucial role in the performance and quality of steel products. With the continuous development and technological advancements in the steel industry, the market demand for high-quality steel is increasing, requiring iron concentrate with higher purity and lower impurity content. For example, in the production of high-end alloy steel, the requirements for the content of impurities such as sulfur and phosphorus in iron concentrate are extremely stringent, and traditional screening and impurity removal methods are insufficient to meet such high quality standards.

[0003] In existing technologies, some devices clean the ore to be processed before processing iron concentrate to prevent impurities from causing substandard processing quality during the processing. However, cleaning the ore requires workers to wash it first before putting it into the machine for processing. This cleaning method is time-consuming and labor-intensive, reducing work efficiency and wasting labor costs. Therefore, a screening and impurity removal device for iron concentrate processing is proposed. Utility Model Content

[0004] This utility model proposes a screening and impurity removal device for iron concentrate processing, which aims to improve the problem of low efficiency and wasted labor costs in some existing devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A screening and impurity removal device for processing iron concentrate includes a first outer shell, a second outer shell movably connected to the top of the first outer shell, two bolts connecting the outer sides of the second outer shell and the inner top wall of the first outer shell, a rotating assembly providing rotational capability on the top of the second outer shell, the rotating assembly including a motor, a rotating shaft, a water guide pipe, and multiple hollow rings, the bottom of the motor being fixedly connected to the top of the second outer shell, one end of the rotating shaft being fixedly connected to the output end of the motor, the outer side of the water guide pipe being fixedly connected to the other end of the rotating shaft, the inner walls of the multiple hollow rings being fixedly connected to the outer side of the water guide pipe, and multiple stirring rods being fixedly connected to the outer side of the hollow rings, the inner walls of the stirring rods having multiple water outlet holes.

[0007] The above technical solution describes a screening and impurity removal device for iron concentrate processing. The outer casings 1 and 2 are securely connected by bolts. Within the rotating assembly, a motor drives a rotating shaft, which in turn rotates the water guide pipe, hollow ring, and stirring rod. Water is sprayed from the outlet holes, effectively mixing the materials and water and improving the screening and impurity removal effect.

[0008] As a further description of the above technical solution:

[0009] Two hydraulic cylinders are fixedly connected inside the outer casing 1. A fixing block 1 is fixedly connected to the output end of the hydraulic cylinders, and a fixing block 2 is fixedly connected to the outside of the fixing block 1.

[0010] The above technical solution involves the output end driving fixed block one, which in turn drives fixed block two to move. This also allows for flexible adjustment of the internal component positions to adapt to different iron concentrate screening and impurity removal requirements, improving equipment applicability and processing efficiency.

[0011] As a further description of the above technical solution:

[0012] Both of the two fixed blocks are slidably connected to a rotating shaft, and both rotating shafts are fixedly connected to a processing cylinder.

[0013] In the above technical solution, the two fixed blocks are slidably connected to the rotating shaft. When the hydraulic cylinder pushes the fixed blocks, the rotating shaft moves smoothly accordingly. The processing cylinder connected to the rotating shaft can be flexibly adjusted in position, facilitating the screening and impurity removal of iron concentrate under different working conditions, thereby improving processing efficiency and quality.

[0014] As a further description of the above technical solution:

[0015] The water guide pipe is fixedly connected to a closed cover on the outside, and a transmission pipe is fixedly connected to the inner wall of the water guide pipe. A docking ring is fixedly connected to the top of the transmission pipe, and an electronic valve is installed inside the transmission pipe.

[0016] The aforementioned technical solution features a sealed cap on the outer side of the water guide pipe to prevent water splashing and ensure safe operation. The inner wall transmission pipe can be connected to other components for water delivery via a connecting ring. The electronic valve can precisely control the water flow and adjust the water volume as needed to meet the water requirements at different stages of iron concentrate screening and impurity removal.

[0017] As a further description of the above technical solution:

[0018] The top inner wall of the first outer shell is provided with a rotating groove, and the interior of the second outer shell is fixedly connected with two fixing rings, the inner wall of which is provided with a rotating groove.

[0019] The above technical solution provides rotation space and guidance for relevant components through the rotation groove one on the inner wall of the top of the outer shell one and the rotation groove two on the inner fixed ring of the outer shell two. This makes the rotation of components smoother, ensures stable equipment operation, facilitates the coordinated work of various components in the iron concentrate screening and impurity removal operation, and improves overall efficiency.

[0020] As a further description of the above technical solution:

[0021] Two connecting pieces are movably connected to the outside of the two fixed rings, and two bolts are inserted and connected to the inner walls of the two fixed rings and the outside of the two connecting pieces.

[0022] In the above technical solution, two connecting pieces are movably connected to the outside of the fixed ring and connected by two bolts. This enhances the stability and integrity of the fixed ring structure, making the internal structure of the outer shell more robust. It ensures the stability of all components during equipment operation, providing a reliable working environment for iron concentrate screening and impurity removal.

[0023] As a further description of the above technical solution:

[0024] A rotating ring is rotatably connected inside the rotating groove two. A water storage cylinder is fixedly connected inside the rotating ring. A rotating groove three is opened on the inner wall of the water storage cylinder. A water guide pipe two is fixedly connected to the inner wall of the water storage cylinder. A docking ring two is fixedly connected to the outside of the water guide pipe two. A base plate is fixedly connected to the bottom of the outer shell one. Two springs one are fixedly connected to the top of the base plate. A slurry discharge inclined plate is fixedly connected to the top of the two springs one. A rotating rod is fixedly connected to the inner wall of the slurry discharge inclined plate. A baffle plate is fixedly connected to the top of the slurry discharge inclined plate. Two dampers are fixedly connected to the bottom of the slurry discharge inclined plate. The bottoms of the two dampers are fixedly connected to the top of the base plate.

[0025] In the above technical solution, the rotating ring inside the rotating trough two drives the water storage cylinder to rotate, facilitating position adjustment. The rotating trough three provides rotation space for internal components. The water guide pipe two connects to other components via the docking ring two, enabling flexible water supply. This makes water storage and transportation more flexible, meeting the water needs of different locations during iron concentrate screening and impurity removal.

[0026] As a further description of the above technical solution:

[0027] A sieving assembly providing rotational capability is fixedly connected to the top of the base plate. The sieving assembly includes a second motor, the bottom of which is fixedly connected to the top of the base plate. A drive shaft is fixedly connected to the output end of the second motor. Two cams are fixedly connected to the outside of the drive shaft. A sieving plate is fixedly connected to the outside of the drive shaft. Two sets of springs are movably connected to the bottom of the sieving plate. A fixing block is fixedly connected to the bottom of each of the two sets of springs. The bottoms of the two fixing blocks are fixedly connected to the top of the base plate. A collecting plate is slidably connected inside the two fixing blocks.

[0028] In the above technical solution, motor two drives the drive shaft, which causes the cam to drive the screen plate to vibrate, achieving efficient screening in conjunction with spring one. A collection plate is installed below the screen plate to conveniently collect the screened material, and fixing block three ensures structural stability, greatly improving screening efficiency and convenience.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, a motor drives a rotating shaft and a water storage tank to rotate. The rotating shaft drives a water guide pipe and multiple hollow rings to rotate. The hollow rings drive a stirring rod to stir inside the processing cylinder. The electronic valve inside the transmission pipe is opened, allowing water from the water storage tank to slowly flow into the water guide pipe. With the motor running, the water flow forms a ring-shaped turbulent current inside the processing cylinder, washing the ore to be processed. This structure achieves the effect of the ore being washed evenly by water, solving the problem of time-consuming and labor-intensive manual washing of ore in some processing methods, thus improving work efficiency and saving labor costs.

[0031] 2. In this utility model, the mud flowing down from the ore is discharged through the holes at the bottom of the processing cylinder, and the discharged mud is discharged through the slurry discharge inclined plate. This structure realizes the effect of directly discharging the mud flowing out of the washed ore outside the device, further improving the separation effect of ore and mud.

[0045] Reference Figures 1 to 10This utility model provides an embodiment of a screening and impurity removal device for iron concentrate processing, comprising a housing 1, which serves as the basic support structure for the entire screening and impurity removal device. A second housing 2 is movably connected to the top of the housing 1, covering the top of the housing 1 and forming a relatively enclosed space together with the housing 1, further protecting the internal components and also providing some dust and water protection.

A docking ring 17 is fixedly connected to the top of transmission pipe 16, which is tightly connected to docking ring 27 to realize the connection between transmission pipe 16 and water guide pipe 26, while ensuring the sealing of the connection to prevent water leakage. An electronic valve is installed inside transmission pipe 16, and a rotating groove 18 is opened on the top inner wall of outer shell 1 to guide the rotation of related components and ensure the stability and accuracy of the components during rotation. Two fixing rings 19 are fixedly connected inside outer shell 2, and the inner wall of fixing ring 19 is opened with a rotating groove 20.

[0047] Two connecting pieces 21 are externally connected to the two fixed rings 19, enhancing the connection stability between the fixed rings 19 and ensuring the overall structural integrity. Two bolts 22 are threaded through and connected to the inner walls of the two fixed rings 19 and the outer surfaces of the two connecting pieces 21. A rotating ring 25 is rotatably connected inside the rotating groove 20. A water storage cylinder 23 is fixedly connected inside the rotating ring 25. A rotating groove 24 is formed on the inner wall of the water storage cylinder 23. A water guide pipe 26 is fixedly connected to the inner wall of the water storage cylinder 23, transporting water from the water storage cylinder 23 to the docking ring 27, and then through the docking ring 17 and the transmission pipe 16 into the water guide pipe 6, providing a water source for the screening and impurity removal process. The bottom of the water pipe 26 is fixedly connected to the docking ring 27. The bottom of the outer shell 1 is fixedly connected to the base plate 40. The top of the base plate 40 is fixedly connected to two springs 28. The top of the two springs 28 is fixedly connected to the slurry discharge inclined plate 29. The inner wall of the slurry discharge inclined plate 29 is fixedly connected to the rotating rod 30. The top of the slurry discharge inclined plate 29 is fixedly connected to the baffle plate 31. The bottom of the slurry discharge inclined plate 29 is fixedly connected to two dampers 32. The bottom of the two dampers 32 is fixedly connected to the top of the base plate 40.

[0048] A sieving assembly providing rotation capability is fixedly connected to the top of the base plate 40. The sieving assembly includes a second motor 33. The bottom of the second motor 33 is fixedly connected to the top of the base plate 40. A drive shaft 34 is fixedly connected to the output end of the second motor 33. Two cams 35 are fixedly connected to the outside of the drive shaft 34. A sieving plate 36 is fixedly connected to the outside of the drive shaft 34. Two sets of second springs 37 are movably connected to the bottom of the sieving plate 36. Fixing blocks 38 are fixedly connected to the bottom of each set of second springs 37. The bottoms of the two fixing blocks 38 are fixedly connected to the top of the base plate 40. A collecting plate 39 is slidably connected inside the two fixing blocks 38.

[0049] Working principle: The operator connects the external hose through docking ring 17 and docking ring 27, puts the ore to be processed into the processing cylinder 14, and then connects the processing cylinder 14 with the appropriate amount of stone into the fixed block 12 through rotating shaft 2 13.

[0050] Two hydraulic cylinders 10 are activated, causing the processing cylinder 14 to rise, placing multiple stirring rods 8 inside the processing cylinder 14. The motor 4 is activated, driving the rotating shaft 5 to rotate. The rotating shaft 5 drives the water guide pipe 6 and multiple hollow rings 7 to rotate. The hollow rings 7 drive the stirring rods 8 to stir inside the processing cylinder 14. The electronic valve outside the transmission pipe 16 is opened, allowing water from the water storage tank 23 to flow into the water guide pipe 6. The water flows through the hollow rings 7 and into the stirring rods 8. During the rotation and stirring process, the water flow forms a ring-shaped turbulence inside the processing cylinder 14, washing and cleaning the ore to be processed.

[0051] The slurry flowing down from the ore flows out through the hole at the bottom of the processing cylinder 14. The separated slurry flows out through the round holes of the screen plate onto the discharge inclined plate 29 (an external container collects the slurry). It is then slowly discharged to the outside of the device through the baffle plate 31. The screen plate is then removed, and the washed stone falls onto the other end of the discharge inclined plate 29. Under the action of gravity, the discharge inclined plate 29 rotates outside the rotating rod 30 to the rear end of the device and falls into the interior of the screen plate 36. The motor 33 is then started to drive the drive shaft. When cam 34 and cam 35 rotate, the rotation of cam 35 generates centrifugal force, which drives the screen plate 36 to vibrate under the action of the spring force released by spring 37, causing the stones to separate by size. Smaller stones fall into the collection plate 39, and the collection plate 39 is pulled to collect the small stones, while the larger stones remain inside the screen plate 36. Since the screen plate 36 is stuck on spring 37, the entire screen plate 36 can be taken out to remove the large stones inside, and the stones are screened by size, which makes subsequent stone processing more convenient and improves work efficiency.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
