Description

Technical Field

[0001] This invention relates to the field of iron ore grinding technology, specifically to an iron ore grinding device with positioning function. Background Technology

[0002] Iron ore is a mineral aggregate containing iron or iron compounds that can be economically utilized. It is an important raw material for steel production enterprises and can be used to refine pig iron and make steel. Iron ore can be classified into magnetite, hematite, limonite and siderite according to its main components. According to its grade, iron ore with a grade of more than 45% is called rich iron ore, and iron ore with a grade of less than 45% is called lean iron ore. In order to improve the grade, the mined low-grade iron ore (such as lean iron ore) can be ground into fine particles and gangue (such as quartz and mica) can be separated through mineral processing (magnetic separation, flotation, etc.) to obtain high-grade iron concentrate (with an iron content of more than 60%) to meet the needs of steel smelting. Due to the influence of its volume, iron ore needs to be packaged in different containers during grinding.

[0003] After the iron ore in the container is ground, the container needs to be disassembled to collect the finished product and then reassembled for the next grinding. However, the pressure applied when the grinding disc is pressed down is difficult to control and will affect the disassembly and reassembly of the container over a long period of time. Therefore, we propose an iron ore grinding device with positioning function. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an iron ore grinding device with positioning function, including a circular base, a hydraulic push rod fixedly connected to the top of the circular base, an annular electric slide rail fixedly connected to the top of the hydraulic push rod, a threaded sleeve rotatably connected to the inner side of the annular electric slide rail, a threaded rod threadedly connected to the inner wall of the threaded sleeve, a circular container fixedly connected to the top of the threaded rod, a bottom support mechanism fixedly connected to the top of the annular electric slide rail, a protective mechanism fixedly connected to the outer side of the threaded sleeve, a vertical frame fixedly connected to the top of the circular base, a circular fixing plate fixedly connected to the inner side of the vertical frame, a drive motor fixedly connected to the bottom of the circular fixing plate, and a grinding mechanism fixedly connected to the bottom of the drive motor.

[0005] The bottom support mechanism includes an annular base plate, with a buffer spring fixedly connected to the top of the annular base plate. Multiple buffer springs are set between the annular support plate and the annular base plate to buffer and reduce vibration of the circular container, preventing the grinding mechanism from generating large-scale vibrations when applying pressure to grind the iron ore inside the circular container, which would affect the fit between the threaded rod and the threaded sleeve. An annular support plate is fixedly connected to the top of the buffer spring, and an annular rubber pad is fixedly connected to the top of the annular support plate. By setting an annular rubber pad, annular support plate, buffer spring, annular base plate, and inner support cylinder at the bottom of the circular container to provide bottom support, the pressure applied by the grinding disc during downward grinding is difficult to control and will affect the disassembly and assembly of the container over a long period of time. The annular rubber pad with a certain degree of elasticity at the bottom of the circular container provides bottom support, which facilitates the circumferential movement adjustment of the circular container after grinding. This avoids the circular container from being in tight contact with the rigid support plate at the bottom during installation, which would make it difficult for the annular electric slide rail to drive the circular container for effective positioning and adjustment.

[0006] There are three hydraulic push rods, which are distributed on the circular base. There are multiple threaded sleeves, which are distributed inside the annular electric slide rail.

[0007] The bottom of the annular base plate is fixedly connected to the top of the annular electric slide rail. Multiple buffer springs are provided, and the multiple buffer springs are distributed between the annular base plate and the annular support plate.

[0008] An inner support cylinder is fixedly connected to the top of the annular base plate. The inner support cylinder is set inside the buffer spring to stabilize the shape of the buffer spring and prevent the buffer spring from being greatly affected by vibration and local twisting during long-term grinding. Multiple inner support cylinders are provided, and the multiple inner support cylinders are respectively distributed on the top of the annular base plate at the position inside the buffer spring.

[0009] Furthermore, the protective mechanism includes an arc-shaped triangular plate. By placing the arc-shaped triangular plate between multiple threaded sleeves, it provides continuous coverage protection for the track area of ​​the annular electric slide rail, preventing small amounts of particulate matter from gradually accumulating within the track during repeated iron ore grinding and processing, thus affecting its use. A fixed vertical rod is fixedly connected to the outer side of the arc-shaped triangular plate. This fixed vertical rod stabilizes the shape of the arc-shaped scraper, preventing it from gradually twisting and bending under the thrust when in contact with the buffer spring, thus affecting subsequent use. An arc-shaped scraper is fixedly connected to one side of the fixed vertical rod. As the arc-shaped triangular plate rotates, the arc-shaped scraper pushes the accumulated particulate matter on the annular base plate outwards and discharges it, preventing it from being discharged during repeated grinding and processing. A small amount of particulate debris generated during production falls onto the annular base plate and accumulates, making it difficult to handle. An arc-shaped brush is fixedly connected to the outer side of the arc-shaped scraper. When the arc-shaped scraper contacts the buffer spring, the arc-shaped brush cleans the surface of the buffer spring and the inner support cylinder, preventing some particulate debris from adhering to the surface of the buffer spring or getting trapped between the buffer spring and the inner support cylinder, thus affecting its use. One side of the arc-shaped triangular plate is fixedly connected to the outer side of the threaded sleeve. Multiple arc-shaped triangular plates are provided, and these plates are distributed between the threaded sleeves. Multiple fixed vertical rods are provided, and these rods are distributed on the outer side of the arc-shaped triangular plates. Multiple arc-shaped brushes are provided, and these brushes are distributed on one side of the arc-shaped scraper.

[0010] Furthermore, the grinding mechanism includes a top receiving plate, with a receiving circular plate fixedly connected to the bottom of the top receiving plate. A conical grinding disc is fixedly connected to the bottom of the receiving circular plate. By setting the grinding disc to a conical shape, the particles ground off at the center are dispersed to the outer area, preventing the accumulation of grinding particles between the iron ore and the grinding disc as the iron ore is gradually ground, thus affecting the direct contact between the grinding disc and the iron ore and impacting the grinding effect. An annular baffle is fitted and fixedly connected to the outer side of the conical grinding disc. By setting the annular baffle on the outer side of the conical grinding disc, the grinding area is surrounded and covered, preventing a large number of particles dispersed by the conical grinding disc from splashing out of the circular container and falling everywhere, making them difficult to handle. An arc-shaped through hole is opened at the top of the conical grinding disc, and an arc-shaped concave shell is slidably connected to the inner wall of the arc-shaped through hole. By setting the arc-shaped concave shell at the top of the arc-shaped grinding disc, the top of the arc-shaped grinding disc is protected. The area is covered with protective coverings to prevent a large amount of grinding particles from accumulating on the top of the arc-shaped grinding disc, affecting the use of the downward pressure spring, and easily overflowing into the arc-shaped through holes. The bottom of the arc-shaped concave shell is fixedly connected to the arc-shaped grinding disc, and the top of the arc-shaped grinding disc is fixedly connected to the downward pressure spring. By setting the downward pressure spring on the top of the arc-shaped grinding disc, downward pressure is applied to cover the grinding particles, preventing a large amount of grinding particles from impacting and splashing around in the circular container, affecting the grinding effect of the grinding disc. The top of the top support plate is fixedly connected to the bottom of the drive motor. There are two arc-shaped through holes, and the two arc-shaped through holes are distributed on the conical grinding disc. The outer side of the arc-shaped grinding disc is slidably connected to the inner wall of the annular baffle. The top of the downward pressure spring is fixedly connected to the bottom of the top support plate. There are multiple downward pressure springs, and the multiple downward pressure springs are distributed on the inner wall of the arc-shaped concave shell.

[0011] This invention provides an iron ore grinding device with positioning function. It has the following beneficial effects:

[0012] 1. This iron ore grinding device with positioning function provides bottom support for the circular container by setting an annular rubber pad, annular support plate, buffer spring, annular bottom plate, and inner support cylinder at the bottom of the container. This prevents the pressure applied by the grinding disc during downward grinding from being difficult to control and affecting the disassembly and assembly of the container over a long period of time. By setting arc-shaped triangular plates between multiple threaded sleeves, the track area of ​​the annular electric slide rail is covered and protected at all times. This prevents small amounts of particle debris from gradually accumulating in the track of the annular electric slide rail during repeated iron ore grinding and affecting its use. By setting the grinding disc to a conical shape, the particles ground off at the center are dispersed to the outer area. This prevents more and more grinding particles from being trapped between the iron ore and the grinding disc as the iron ore is gradually ground, affecting the direct contact between the grinding disc and the iron ore and thus the grinding effect.

[0013] 2. This iron ore grinding device with positioning function is equipped with a bottom support mechanism. A ring-shaped rubber pad, a ring-shaped support plate, buffer springs, a ring-shaped bottom plate, and an inner support cylinder are installed at the bottom of the circular container to provide bottom support. This prevents the pressure applied during grinding from being difficult to control and affecting the container's assembly and disassembly over time. The elastic ring-shaped rubber pad at the bottom of the circular container facilitates the circumferential movement adjustment of the container after grinding, preventing the bottom of the circular container from being in tight contact with the rigid support plate during installation, which would make it difficult for the ring-shaped electric slide rail to drive the container for effective positioning adjustment. Multiple buffer springs are installed between the ring-shaped support plate and the ring-shaped bottom plate to buffer and dampen the circular container, preventing significant vibrations during grinding of the iron ore inside the container that could affect the fit between the threaded rod and the threaded sleeve. An inner support cylinder is installed inside the buffer springs to stabilize their shape, preventing them from being excessively affected by vibrations and causing localized twisting during prolonged grinding, thus affecting their use.

[0014] 3. This iron ore grinding device with positioning function is equipped with a protective mechanism. An arc-shaped triangular plate is placed between multiple threaded sleeves to continuously cover and protect the track area of ​​the annular electric slide rail. This prevents small amounts of particulate matter from accumulating within the track during repeated iron ore grinding, thus affecting its use. As the arc-shaped scraper rotates with the arc-shaped triangular plate, it pushes the accumulated particulate matter on the annular base plate outwards, preventing it from accumulating and becoming difficult to handle. A fixed vertical rod is installed outside the arc-shaped triangular plate to stabilize the shape of the arc-shaped scraper, preventing it from gradually twisting and bending under the thrust when in contact with the buffer spring, thus affecting subsequent use. When the arc-shaped scraper contacts the buffer spring, the arc-shaped brush on its surface cleans the surface of the buffer spring and the inner support cylinder, preventing particulate matter from adhering to the surface of the buffer spring or getting trapped between the buffer spring and the inner support cylinder, thus preventing it from affecting its use.

[0015] 4. This iron ore grinding device with positioning function is equipped with a grinding mechanism. By setting the grinding disc to a conical shape, the particles ground off at the center are dispersed to the outer area. This prevents the increasing amount of grinding particles trapped between the iron ore and the grinding disc as the iron ore is gradually ground, which would affect the direct contact between the grinding disc and the iron ore and thus the grinding effect. An annular baffle is set on the outside of the conical grinding disc to surround and cover the grinding area, preventing a large number of particles dispersed by the conical grinding disc from splashing out of the circular container and falling everywhere, which would be difficult to handle. A downward pressure spring is set on the top of the arc-shaped grinding disc to apply downward pressure to cover the grinding particles, preventing a large number of grinding particles from impacting and splashing around in the circular container and affecting the grinding effect of the grinding disc. An arc-shaped concave shell is set on the top of the arc-shaped grinding disc to cover and protect the top area of ​​the arc-shaped grinding disc, preventing a large number of grinding particles from accumulating on the top of the arc-shaped grinding disc, affecting the use of the downward pressure spring, and easily overflowing into the arc-shaped through hole.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-4 The present invention provides an iron ore grinding device with positioning function, including a circular base 1, a hydraulic push rod 2 fixedly connected to the top of the circular base 1, an annular electric slide rail 3 fixedly connected to the top of the hydraulic push rod 2, a threaded sleeve 4 rotatably connected to the inner side of the annular electric slide rail 3, a threaded rod 5 threadedly connected to the inner wall of the threaded sleeve 4, a circular container 6 fixedly connected to the top of the threaded rod 5, a bottom support mechanism 7 fixedly connected to the top of the annular electric slide rail 3, a protective mechanism 8 fixedly connected to the outer side of the threaded sleeve 4, a vertical frame 9 fixedly connected to the top of the circular base 1, a circular fixing plate 10 fixedly connected to the inner side of the vertical frame 9, a drive motor 11 fixedly connected to the bottom of the circular fixing plate 10, and a grinding mechanism 12 fixedly connected to the bottom of the drive motor 11.

[0027] The bottom support mechanism 7 includes an annular base plate 701, a buffer spring 702 is fixedly connected to the top of the annular base plate 701, an annular support plate 703 is fixedly connected to the top of the buffer spring 702, and an annular rubber pad 704 is fixedly connected to the top of the annular support plate 703.

[0028] There are three hydraulic push rods 2, and the three hydraulic push rods 2 are distributed on the circular base 1. There are multiple threaded sleeves 4, and the multiple threaded sleeves 4 are distributed inside the annular electric slide rail 3.

[0029] The bottom of the annular base plate 701 is fixedly connected to the top of the annular electric slide rail 3. Multiple buffer springs 702 are provided, and the multiple buffer springs 702 are distributed between the annular base plate 701 and the annular support plate 703.

[0030] An inner support cylinder 705 is fixedly connected to the top of the annular base plate 701. Multiple inner support cylinders 705 are provided, and they are distributed at the top of the annular base plate 701, located inside the buffer spring 702. In use, the iron ore to be ground is placed sequentially into multiple circular containers 6. The hydraulic push rod 2 pushes the annular electric slide rail 3, causing the top support mechanism 7, threaded sleeve 4, protective mechanism 8, threaded rod 5, and circular containers 6 to move upwards together. At this time, the drive motor 11 is started, driving the grinding mechanism 12 to rotate. The continuously moving circular containers 6 allow the grinding mechanism 12 to gradually enter the circular containers 6 to grind the iron ore. When the iron ore is continuously ground under pressure inside the grinding machine 6, the bottom support mechanism 7 at the bottom of the circular container 6 provides buffer support. After grinding is completed, the circular container 6 is moved down a distance away from the grinding mechanism 12 by the hydraulic push rod 2 driving the annular electric slide rail 3. The annular electric slide rail 3 drives the threaded sleeve 4 to move the next circular container 6 to the bottom of the grinding mechanism 12 in a circular motion for grinding again. At the same time, the circular container 6 that has been ground can be rotated to drive the threaded rod 5 and the threaded sleeve 4 to engage in threaded engagement for disassembly. When the threaded sleeve 4 rotates in a circular motion, it drives the protective mechanism 8 to rotate together and handle the surrounding dust and residual debris.

[0031] The circular container 6 is rotated and installed by the threaded engagement of the threaded rod 5 and the threaded sleeve 4. As the circular container 6 rotates and moves downward, it contacts and compresses the annular rubber pad 704. At the same time, it pushes the bottom annular support plate 703 downward to compress the buffer spring 702 until the annular support plate 703 moves downward and stops when it comes into contact with the inner support cylinder 705. The circular container 6 is supported at the bottom by the annular rubber pad 704, the annular support plate 703, the buffer spring 702, the annular base plate 701, and the inner support cylinder 705. The annular rubber pad 704 with a certain elasticity is used to support the bottom of the circular container 6, which facilitates the circumferential movement adjustment of the circular container 6 after grinding. Multiple buffer springs 702 are set between the annular support plate 703 and the annular base plate 701 to buffer and dampen the circular container 6. The inner support cylinder 705 is set inside the buffer spring 702 to stabilize its shape.

[0032] Please see Figures 1-8The present invention provides an iron ore grinding device with positioning function: the protective mechanism 8 includes an arc-shaped triangular plate 801, a fixed vertical rod 802 is fixedly connected to the outer side of the arc-shaped triangular plate 801, an arc-shaped scraper 803 is fixedly connected to one side of the fixed vertical rod 802, an arc-shaped brush 804 is fixedly connected to the outer side of the arc-shaped scraper 803, one side of the arc-shaped triangular plate 801 is fixedly connected to the outer side of the threaded sleeve 4, multiple arc-shaped triangular plates 801 are provided, and multiple arc-shaped triangular plates 801 are respectively distributed between the threaded sleeves 4, multiple fixed vertical rods 802 are provided, and multiple fixed vertical rods 802 are distributed on the outer side of the arc-shaped triangular plate 801, and multiple arc-shaped brushes 804 are provided, and multiple arc-shaped brushes 804 are distributed on one side of the arc-shaped scraper 803;

[0033] The grinding mechanism 12 includes a top receiving plate 1201, a receiving circular plate 1202 fixedly connected to the bottom of the top receiving plate 1201, a conical grinding disc 1203 fixedly connected to the bottom of the receiving circular plate 1202, an annular baffle 1204 sleeved and fixedly connected to the outer side of the conical grinding disc 1203, an arc-shaped through hole 1205 opened at the top of the conical grinding disc 1203, an arc-shaped concave shell 1206 slidably connected to the inner wall of the arc-shaped through hole 1205, an arc-shaped grinding disc 1207 fixedly connected to the bottom of the arc-shaped concave shell 1206, a downward pressure spring 1208 fixedly connected to the top of the arc-shaped grinding disc 1207, and a top of the top receiving plate 1201 fixedly connected to the bottom of the drive motor 11. Two arc-shaped through holes 1205 are provided, and the two arc-shaped through holes... 1205 is distributed on the conical grinding disc 1203. The outer side of the arc-shaped grinding disc 1207 is slidably connected to the inner wall of the annular baffle 1204. The top of the compression spring 1208 is fixedly connected to the bottom of the top support plate 1201. Multiple compression springs 1208 are provided, and multiple compression springs 1208 are distributed on the inner wall of the arc-shaped concave shell 1206. In use, when the annular electric slide rail 3 drives the threaded sleeve 4 to rotate in a circular motion, it drives the outer arc-shaped triangular plate 801 to rotate together. By setting the arc-shaped triangular plate 801 between multiple threaded sleeves 4, the track area of ​​the annular electric slide rail 3 is covered and protected at all times. When the arc-shaped triangular plate 801 rotates, it drives the outer fixed vertical rod 802 and the arc-shaped scraper 803 to rotate together. As the arc-shaped triangular plate 801 rotates, the scraper 803 pushes the accumulated particles and debris on the annular base plate 701 outwards, causing them to fall out and be discharged. As the arc-shaped scraper 803 continues to rotate, it contacts the buffer spring 702 and bends under the thrust until it is close to the edge of the arc-shaped triangular plate 801. It then passes between the buffer spring 702 and the arc-shaped triangular plate 801. A fixed vertical rod 802 is installed on the outside of the arc-shaped triangular plate 801 to stabilize the shape of the arc-shaped scraper 803. When the arc-shaped scraper 803 contacts the buffer spring 702, the arc-shaped brush 804 on its surface cleans the surface of the buffer spring 702 and the surface of the inner support cylinder 705. As the circular container 6 is pushed upwards, it gradually approaches the conical grinding disc 1203, and simultaneously, the drive motor is activated. 11 drives the top receiving plate 1201 to rotate. When the top receiving plate 1201 rotates, it drives the conical grinding disc 1203 to rotate through the bottom receiving circular plate 1202. When the rotating conical grinding disc 1203 comes into contact with the iron ore in the circular container 6, it grinds the iron ore. By setting the grinding disc to a conical shape, it is easy to disperse the particles ground off in the center to the outer area. An annular baffle 1204 is set on the outside of the conical grinding disc 1203 to surround and cover the grinding area. At the same time, the arc-shaped grinding disc 1207 on the inner wall of the annular baffle 1204 near the outer edge rotates with the conical grinding disc 1203 to perform fine grinding on the particles dispersed to the outside. Meanwhile, the downward pressure spring 1208 at the top of the arc-shaped grinding disc 1207 constantly applies downward pressure to it.The grinding particles are compressed by applying downward pressure through a compression spring 1208 at the top of the arc-shaped grinding disc 1207, and the top area of ​​the arc-shaped grinding disc 1207 is covered and protected by an arc-shaped concave shell 1206.

[0034] In operation, the iron ore to be ground is placed sequentially into multiple circular containers 6. A hydraulic pusher 2 pushes the annular electric slide rail 3, causing the top support mechanism 7, threaded sleeve 4, protective mechanism 8, threaded rod 5, and circular containers 6 to move upwards together. At this time, the drive motor 11 is activated, causing the grinding mechanism 12 to rotate. The continuously moving circular containers 6 allow the grinding mechanism 12 to gradually enter the circular containers 6 to grind the iron ore. As the grinding mechanism 12 enters the circular containers 6 and continuously applies pressure to grind the iron ore, the bottom support mechanism 7 at the bottom of the circular containers 6 provides cushioning. During the grinding process, the circular container 6 is moved down a distance from the grinding mechanism 12 by the hydraulic push rod 2 to the annular electric slide rail 3 after grinding. The annular electric slide rail 3 drives the threaded sleeve 4 to move the next circular container 6 to the bottom of the grinding mechanism 12 in a circular motion for grinding again. At the same time, the previously ground circular container 6 can be rotated to drive the threaded rod 5 and the threaded sleeve 4 to engage in threaded engagement for disassembly. When the threaded sleeve 4 rotates in a circular motion, it drives the protective mechanism 8 to rotate together and handle the surrounding dust and residual debris.

[0035] The circular container 6 is rotated and installed by the threaded engagement of the threaded rod 5 and the threaded sleeve 4. As the circular container 6 rotates and moves downward, it contacts and compresses the annular rubber pad 704. Simultaneously, it pushes the bottom annular support plate 703 downward, compressing the buffer spring 702 until the annular support plate 703 moves downward and stops when its bottom surface contacts the inner support cylinder 705. The circular container 6 is supported at the bottom by the annular rubber pad 704, the annular support plate 703, the buffer spring 702, the annular bottom plate 701, and the inner support cylinder 705. The presence of a certain degree of elasticity in the annular rubber pad 704 at the bottom of the circular container 6 facilitates the circular motion adjustment of the circular container 6 after grinding. The circular container 6 is cushioned and damped by multiple buffer springs 702 between the annular support plate 703 and the annular base plate 701. The buffer springs 702 are stabilized by an inner support cylinder 705. When the annular electric slide rail 3 drives the threaded sleeve 4 to rotate in a circular motion, it also drives the outer arc-shaped triangular plate 801 to rotate. The arc-shaped triangular plate 801 between the multiple threaded sleeves 4 provides constant coverage protection for the track area of ​​the annular electric slide rail 3. When the arc-shaped triangular plate 801 rotates, it drives the outer fixed vertical rod 802 and the arc-shaped scraper 803 to rotate together. As the arc-shaped triangular plate 801 rotates, the arc-shaped scraper 803 pushes away the accumulated particulate matter on the annular base plate 701. As the scraper blade 803 continues to rotate, it contacts the buffer spring 702 and bends under the thrust until it is close to the edge of the arc-shaped triangular plate 801. It then passes between the buffer spring 702 and the arc-shaped triangular plate 801. A fixed vertical rod 802 is installed on the outside of the arc-shaped triangular plate 801 to stabilize the shape of the scraper blade 803. When the scraper blade 803 contacts the buffer spring 702, the arc-shaped brush 804 on its surface cleans the surface of the buffer spring 702 and the surface of the inner support cylinder 705. As the circular container 6 is pushed upwards, it gradually approaches the conical grinding disc 1203. Simultaneously, the drive motor 11 is activated, causing the top receiving plate 1201 to rotate. As the top receiving plate 1201 rotates, it passes through the bottom receiving circular plate 120... 2. The conical grinding disc 1203 rotates, and when the rotating conical grinding disc 1203 comes into contact with the iron ore in the circular container 6, it grinds the ore. By setting the grinding disc to a conical shape, the particles ground off at the center are dispersed to the outer area. An annular baffle 1204 is set on the outside of the conical grinding disc 1203 to surround and cover the grinding area. At the same time, the arc-shaped grinding disc 1207 on the inner wall of the annular baffle 1204 near the outer edge rotates with the conical grinding disc 1203 to finely grind the particles dispersed to the outside. Meanwhile, the downward pressure spring 1208 at the top of the arc-shaped grinding disc 1207 constantly applies downward pressure to it, thereby compressing the particles generated during grinding.An arc-shaped concave shell 1206 is provided on top of the arc-shaped grinding disc 1207 to provide a covering protection for the top area of ​​the arc-shaped grinding disc 1207.
