Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing, in particular to an iron processing structure for a lepidolite crushing workshop. Background Art

[0002] In the ore crushing process, crushing equipment is used in the crushing workshop to separate useful minerals from gangue minerals or different useful minerals in the ore, or to reduce the particle size of the materials to meet the requirements of the separation operation. Cone crushers are a common type of equipment used for crushing raw materials such as rocks and ores. Due to their high crushing ratio, high efficiency, low energy consumption, and uniform product particle size, they are widely used in secondary and fine crushing operations in the mining and building materials industries.

[0003] During crusher operation, unbreakable material often enters the crushing chamber, causing iron to become stuck between the movable and fixed cone liners, leading to crusher failure. This is especially true when the material has not undergone a de-ironing process before entering the crusher, resulting in inclusions of iron and other foreign matter. This can cause the crusher to shut down unexpectedly or damage key components, disrupting the entire production line and causing significant financial losses for the user. When unbreakable material enters the crushing chamber, an over-iron protection device allows it to pass smoothly through the crushing chamber. Existing de-ironing devices, for various reasons, cannot completely remove large iron pieces, compromising the normal and safe operation of the cone crusher and severely impacting its production capacity. Utility Model Content

As such, variations in the shapes of these illustrations are to be expected, for example, as a result of manufacturing techniques and / or tolerances. The various aspects of the present invention shown in the drawings may not necessarily be drawn to scale. Furthermore, some of the drawings have been simplified for the sake of clarity. Consequently, the drawings may not depict all of the various components of a given apparatus (e.g., device) or method. Therefore, the components shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shape of the components and are not intended to limit the scope of the present invention.

[0028] Reference Figures 1 to 5 As shown, the iron processing structure of the lithium mica crushing workshop described in the utility model includes a circular feeding barrel 1 and a base 2. The circular feeding barrel 1 is arranged above the base 2, and the base 2 is fixed to support the circular feeding barrel 1 upward. The main body of the circular feeding barrel 1 adopts a horizontally arranged cylindrical structure, similar to the shape of a mounted drum. The interior of the circular feeding barrel 1 is a cavity, and the central axis of the circular feeding barrel 1 is located in the horizontal direction. A rotating roller 3 is provided at the center position of the circular feeding barrel 1, and the rotating roller 3 and the circular feeding barrel 1 have the same center. The rotating roller 3 passes through the center position of the circular feeding barrel 1, and is movably and rotatably connected to the circular feeding barrel 1 through bearings at the front and rear ends of the circular feeding barrel 1.

[0029] A drive shaft 4 is provided at the center of the rotating roller 3. The drive shaft 4 is driven by a drive motor 5 on one side of the outside, and the drive shaft 4 drives the rotating roller 3 to rotate. The drive motor 5 is fixed to the rear vertical surface of the circular feeding drum 1 via a mounting bracket. The drive motor 5 is preferably a stepper motor or a servo motor. The drive motor 5 rotates forward and reverse under the control of a PLC control system.

[0030] A feed channel 6 is provided at the top of the circular feeding barrel 1. The top opening of the feed channel 6 is a feed port 7. The bottom of the feed channel 6 is interconnected with the interior of the circular feeding barrel 1. A discharge channel 8 is provided at the bottom of the circular feeding barrel 1. The top of the discharge channel 8 is interconnected with the interior of the circular feeding barrel 1. The bottom opening of the discharge channel 8 is a discharge port 9. The discharge channel 8 is located in the base 2 at the bottom of the circular feeding barrel 1 and is fixedly connected to the base 2. An iron discharge channel 10 is provided on the side wall of the circular feeding barrel 1. The iron discharge channel 10 is arranged on the outside of the circular feeding barrel 1 at an angle downward, and the iron discharge channel 10 is interconnected with the interior of the circular feeding barrel 1. The end opening of the iron discharge channel 10 is an iron discharge port 11.

[0031] When the mineral material to be processed enters the circular feeding barrel 1 through the feed port 7, the mineral material after being processed to remove large iron pieces in the circular feeding barrel 1 is discharged to the outside through the discharge port 9, and the detected large iron pieces will be discharged from the inside of the circular feeding barrel 1 through the iron discharge channel 10.

[0032] A plurality of partition plates 13 are arranged in an array on the outer circumference of the rotating roller 3. The partition plates 13 preferably have a square plate structure, and reinforcing ribs are provided on the partition plates 13 along the radial direction of the rotating roller 3. The partition plates 13 are spaced apart on the outer circumference of the rotating roller 3, dividing the space between the rotating roller 3 and the circular feed drum 1 into a plurality of small spaces at equal distances. Preferably, six to eight partition plates 13 are spaced apart on the outer circumference of the rotating roller 3. When the feed channel 6 corresponds to a certain space formed by the partition plates 13, the iron discharge channel 10 will correspond to another different space.

[0033] When the mineral material to be processed enters the feed channel 6 through the feed port 7, it enters the space formed by the partition plate 13 facing the feed channel 6 from the top of the circular feed cylinder 1. As the drive motor 5 drives the rotating roller 3 to rotate in a uniform forward direction, the mineral material successively enters the multiple spaces formed by the partition plate 13, and is carried by the corresponding spaces to the discharge channel 8 at the bottom of the circular feed cylinder 1. After falling into the discharge channel 8, it is discharged downward through the discharge port 9. The discharge port 9 can be used in conjunction with the feed end of the crushing equipment to directly put the mineral material excluding large iron pieces into the crushing equipment for crushing operation. Figure 4 As shown, line A shows the path of the mineral material during normal operation.

[0034] A convex fan portion 14 is provided at the end extending from the partition plate 13. The convex fan portion 14 is integrally formed with the partition plate 13, and the arc segment of the convex fan portion 14 cooperates with the arc of the inner wall of the circular feed barrel 1 to form an approximately fitting slit to reduce the gap between the partition plate 13 and the circular feed barrel 1.

[0035] An automatic sensing device 15 is provided on the outer side of the tube wall of the feed channel 6 at the top of the circular feeding cylinder 1. The automatic sensing device 15 is sleeved on the outer side of the tube wall of the feed channel 6 to detect large iron pieces of the mineral materials entering the feed channel 6, automatically sense and identify the large iron pieces, and issue an alarm. The automatic sensing device 15 feeds back the alarm signal to the PLC control system. After receiving the alarm signal, the PLC control system controls the rotating roller 3 that is rotating in the forward direction to stop rotating, and then controls the rotating roller 3 to rotate in the reverse direction by a certain angle, so that the iron discharge channel 10 can correspond to the space between the two receding circular feeding cylinders or the base, and discharge the large iron pieces detected therein through the iron discharge channel 10 in a timely manner. Then, the rotating roller 3 resumes normal forward rotation and continues to work without affecting the production line. Figure 5 As shown, line B shows the path of the mineral material during iron discharge.

[0036] An inspection door 12 is provided on the front vertical surface of the circular feed cylinder 1 below the rotating roller 3. The inspection door 12 is movably connected to the circular feed cylinder 1 and seals the internal cavity of the circular feed cylinder 1. When the interior of the circular feed cylinder 1 needs to be inspected, the inspection door 12 can be opened to view the interior of the circular feed cylinder 1, facilitating the inspection operation.

[0037] During the implementation of the present invention, the circular feed cylinder 1 is arranged above the base 2, and the base 2 is fixed upward to support the circular feed cylinder 1. A rotating roller 3 is arranged at the center of the circular feed cylinder 1, and a driving shaft 4 is arranged at the center of the rotating roller 3. The driving shaft 4 is driven by a driving motor 5 on one side of the outside, and the driving shaft 4 drives the rotating roller 3 to rotate together.

[0038] A plurality of partition plates 13 are arranged in an array around the outer circumference of the rotating roller 3. These partition plates 13 are spaced apart at intervals around the outer circumference of the rotating roller 3, dividing the space between the rotating roller 3 and the circular feed drum 1 into a plurality of equally spaced smaller compartments. While the feed channel 6 corresponds to a compartment formed by the partition plates 13, the iron discharge channel 10 may correspond to a different compartment.

[0039] After the mineral material to be processed enters the feed channel 6 through the feed port 7, it enters the space formed by the partition plates 13 facing the feed channel 6 from the top of the circular feed drum 1. As the drive motor 5 drives the rotating roller 3 to rotate in a uniform forward direction, the mineral material successively enters the multiple spaces formed by the partition plates 13 and is carried by the corresponding spaces. When it reaches the discharge channel 8 at the bottom of the circular feed drum 1, it falls into the discharge channel 8 and is discharged downward through the discharge port 9.

[0040] An automatic sensing device 15 is provided on the outer side of the tube wall of the feed channel 6 at the top of the circular feeding barrel 1. The automatic sensing device 15 is sleeved on the outer side of the tube wall of the feed channel 6 to detect large iron pieces of mineral materials entering the feed channel 6, automatically sense and identify the large iron pieces, and issue an alarm. The automatic sensing device 15 feeds back the alarm signal to the PLC control system.

[0041] After receiving the alarm signal, the PLC control system controls the rotating roller 3 that is rotating in the forward direction to stop rotating, and then controls the rotating roller 3 to rotate in the reverse direction by a certain angle, so that the iron discharge channel 10 can correspond to the space between one of the retreating circular feeding cylinders or two bases, and discharge the large iron pieces detected therein through the iron discharge channel 10 in time.

[0042] Through the above operation, the mineral material to be processed enters the circular feed drum 1 through the feed port 7. After the large iron pieces are removed in the circular feed drum 1, the mineral material is discharged to the outside through the discharge port 9. The detected large iron pieces will be discharged from the interior of the circular feed drum 1 through the iron discharge channel 10. After the iron is discharged, the rotating roller 3 resumes normal forward rotation and continues to work without affecting the production line's production efficiency.

[0043] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
