Description

[0001] The present application relates to the technical field of ore conveying equipment, and particularly relates to an ore screening and crushing device. BACKGROUND

[0002] In the smelting process, generally, the ore is fed by a trough conveying belt conveyor, and the smelting quality is ensured by setting the supporting roller as an arc shape and making the conveying belt present a groove shape with high sides and low middle.

[0042] Referring to Figure 1 A mineral aggregate screening and crushing device, comprising a conveying belt conveyor 1, a discharging mechanism 2, a screening mechanism 3, and a surplus material recycling mechanism 4. The conveying belt conveyor 1 is a modified version of a trough-type conveying belt conveyor. The specific modification method is described in Figure 2The end of the trough type conveying belt machine is extended, and the conveying belt is adjusted from the trough type to the flat type through the flattening assembly 12, so that the conveying belt machine 1 is divided into the trough type feeding section 11 and the flat type discharging section 13 by the flattening assembly 12, the discharging mechanism 2 capable of adjusting the discharging direction is installed at the discharging section 13, the ore flow direction of different bins can be adjusted by adjusting the discharging direction, so that the stability of the feeding process is ensured. Further, the present application adopts the non-contact discharging, and the gap 6 is left between the discharging mechanism 2 and the conveying belt machine 1, so that the friction between the discharging mechanism 2 and the conveying belt machine 1 is reduced, and the service life is improved. The screening mechanism 3 corresponding to the discharging mechanism 2 is arranged on both sides of the conveying belt machine 1, the lump ore mixed in the ore can be separated out through the screening mechanism 3, so that the smelting quality is ensured; the residual material recovery mechanism 4 for recovering the ore leaked from the gap 6 is also installed at the bottom of the discharging section 13, and the utilization rate of resources is improved.

[0043] In some embodiments, referring to Figures 3-5The flattening assembly 12 comprises an adjusting box 122, an adjusting block 123, adjusting teeth 124, a compression roller 126 and a clamping tooth 1291. The adjusting box 122 is a square box structure, and two adjusting boxes 122 are symmetrically fixed at the two ends of a first supporting plate 121, which is fixedly connected to the support of the conveying belt machine 1. The adjusting block 123 is slidably connected in the adjusting box 122, and the compression roller 126 corresponding to the conveying belt of the conveying belt machine 1 is rotatably installed on the adjusting block 123. The two sides of the conveying belt are pressed down by the compression roller 126, so that the conveying belt changes from a groove type to a flat type, thereby facilitating unloading. Due to the wear problem of the compression roller 126 after long-term use, the two sides of the conveying belt cannot be pressed flat, which affects the flatness at the unloading section 13. Therefore, the flattening assembly 12 is designed to be adjustable. When the diameter of the compression roller 126 becomes smaller due to wear, the pressing distance of the compression roller 126 can be adjusted to ensure the flatness of the conveying belt at the unloading section 13, thereby facilitating unloading. The adjusting teeth 124 are evenly arranged on the left and right sides of the adjusting block 123, and the clamping tooth 1291 corresponding to the adjusting teeth is slidably installed on the adjusting box 122. By clamping the clamping tooth 1291 at different positions of the adjusting teeth 124, the height position of the compression roller 126 can be adjusted to adjust the pressing distance of the compression roller 126 and ensure the flatness at the unloading section 13. Further, a wing plate 127 is arranged on the side of the adjusting box 122 to facilitate the adjustment of the pressing distance of the compression roller 126. The guide rod 1271 is fixed on the wing plate 127 in the transverse direction, and the sliding block 129 is slidably connected to the guide rod 1271. The clamping tooth 1291 is arranged at the end of the sliding block 129 and corresponds to the adjusting teeth 124. A second spring 128 is arranged between the sliding block 129 and the wing plate 127, and the second spring 128 is always in a compressed state. When adjusting, the adjusting block 123 is directly pressed, the clamping tooth 1291 is pressed by the adjusting teeth 124, the sliding block 129 is slid outward, the second spring 128 is compressed, and after the adjustment is completed, the sliding block 129 drives the clamping tooth 1291 to tightly press the adjusting teeth 124 to fix the adjusting block 123. To avoid excessive adjustment caused by excessive force when pressing the adjusting block 123, a first spring 125 is arranged at the bottom of the adjusting box 122. The end of the first spring 125 is fixedly connected to the adjusting block 123, and the first spring 125 is always in a compressed state, thereby increasing the resistance when pressing the adjusting block 123 and improving the stability of the adjustment process. To ensure the stability of the sliding process of the adjusting block 123, a limiting groove 1231 is formed on the adjusting block 123, and a limiting protrusion is arranged on the adjusting box 122. The adjusting block 123 is slidably connected to the limiting protrusion through the limiting groove 1231.

[0044] In order to further improve the flatness of the discharging section 13, a first support 14 is further fixed on the support of the conveying belt machine 1, and a supporting roller 15 is rotatably installed on the first support 14, the supporting roller 15 abuts against the bottom surface of the conveying belt at the discharging section 13 to prevent the conveying belt from sagging due to the weight of the materials, and to keep the conveying belt flat, thereby facilitating the discharging.

[0045] In some embodiments, referring to Figure 2 、 5 The discharging mechanism 2 comprises a second support 22, a first telescopic rod 24, a reversing plate 28, and a discharging plate 29, the second support 22 is fixedly installed on the fixed plate 21, the fixed plate 21 is fixed on the floor 5 of the upper layer of the factory building, a connecting head 26 is welded and fixed at the end of the second support 22, a third support 27 is arranged at the middle position of the reversing plate 28, and the connecting head 26 is hingedly connected with the third support 27; a first support 23 is further arranged on the fixed plate 21, a second support 25 is arranged at the eccentric position of the reversing plate 28, one end of the first telescopic rod 24 is hingedly connected with the first support 23, and the other end is hingedly connected with the second support 25, and by controlling the extension amount of the first telescopic rod 24, the reversing plate 28 can be rotated around the third support 27, thereby changing the discharging direction.

[0046] Further, referring to Figure 7 The discharging plate 29 is fixedly installed on the reversing plate 28, and a gap 6 is left between the bottom surface of the discharging plate 29 and the conveying belt of the conveying belt machine 1, and the width of the gap 6 is 5-10 mm, since the diameters of the block ores to be screened out of the materials are all above 30 mm, the materials passing through the gap 6 can be directly smelted. By arranging the gap 6, the discharging plate 29 is not in contact with the conveying belt, thereby reducing the friction between the discharging plate 29 and the conveying belt, and improving the service life thereof. During discharging, the materials on the conveying belt are guided by the discharging plate 29 to fall into the screening mechanism 3 for screening, and due to the gap 6, a small amount of materials can pass through the gap 6, and are collected by the excess material recycling mechanism 4, thereby avoiding the leakage of the materials.

[0047] In some embodiments, referring to Figure 8The screening mechanism 3 comprises a screening box 31, a partition plate 32, a screen 33, and a blockage cleaning assembly 36. The two screening boxes 31 are respectively arranged on the left and right sides of the discharge section 13. The first discharge cavity 37 and the second discharge cavity 38 are separated by the partition plate 32 in the screening box 31. The top of the first discharge cavity 37 is obliquely provided with the screen 33. The screen 33 can screen the lump ore. The bottom of the first discharge cavity 37 is connected to the stock bin 71 through the discharge pipe 7. The second discharge cavity 38 is connected to the crusher 83 through the lump ore guide pipe 8. The screen 33 is a strip-shaped screen. Because the lump ore is usually not uniform in shape, and the lump ore has a large impact on the screen 33 during the discharging process, the lump ore is easily stuck on the screen 33 during the screening process. Therefore, the blockage cleaning assembly 36 for cleaning the lump ore stuck on the screen 33 is further arranged in the screening box 31. Further, the side plates 34 are arranged on the left and right sides of the screen 33 to prevent the ore from spilling. The baffle 35 is further arranged on the screening box 31 to guide the lump ore and facilitate the lump ore to fall into the lump ore guide pipe 8. Figure 12 After the ore mixed with the lump ore falls into the screening mechanism 3, the ore for smelting directly passes through the screen 33, is guided into the stock bin 71 through the discharge pipe 7 from the first discharge cavity 37, and waits for smelting. The lump ore is blocked by the screen 33 and falls along the screen 33 to the second discharge cavity 38, is guided into the lump ore bin 81 through the lump ore guide pipe 8, and is collected. The vibration feeder 82 is arranged at the bottom of the lump ore bin 81. The lump ore is conveyed to the crusher 83 through the vibration feeder 82 for crushing. The crushed ore is guided into the stock bin 71 and waits for smelting.

[0048] Referring to Figure 9 The blockage cleaning assembly 36 comprises a second telescopic rod 362, a cleaning frame 363, and a cleaning rod 364. The second telescopic rod 362 is fixedly arranged on the second supporting plate 361 in the vertical direction. The second supporting plate 361 is fixed in the screening box 31. The cleaning frame 363 is fixedly connected to the end of the second telescopic rod 362. The cleaning rods 364 corresponding to the gaps of the screen 33 are uniformly arranged on the cleaning frame 363. The cleaning rods 364 are parallel to the screen 33. The length of the cleaning rods 364 is consistent with the length of the strip-shaped screen holes of the screen 33. In use, the second telescopic rod 362 is controlled to be elongated, the cleaning frame 363 is driven to rise, and the cleaning rods 364 are extended from the strip-shaped screen holes, so that the lump ore stuck in the screen holes is lifted to complete the cleaning.

[0049] In some embodiments, referring to Figure 10The excess material recycling mechanism 4 comprises a recycling box 41, a cleaning brush 42, a recycling pipe 43, a sealing plate 44, a fixing assembly 45, and a vibrating motor 46. The recycling box 41 is fixedly arranged at the bottom of the discharging section 13, and the bottom surface of the recycling box 41 is inclined. Two recycling pipes 43 are respectively connected to different material bins 71 at the lowest position of the bottom of the recycling box 41. The sealing plate 44 is arranged in the recycling box 41 by the fixing assembly 45. The recycling pipe 43 can be blocked by the sealing plate 44, so as to control the flow direction of the mineral materials. The cleaning brush 42 is arranged in the recycling box 41 for cleaning the conveying belt. The vibrating motor 46 is arranged at the bottom of the recycling box 41 for facilitating discharging. During use, a small amount of mineral materials passing through the gap 6 fall into the recycling box 41 under the action of gravity. The conveying belt of the conveying belt machine 1 can be cleaned by the cleaning brush 42, so as to avoid the adhesion of the mineral materials on the conveying belt. The mineral materials in the recycling box 41 are guided into the material bin 71 from the recycling pipe 43 under the action of the vibrating motor 46. The recycling pipe 43 can be blocked by the sealing plate 44, so as to control the flow direction of the mineral materials to the designated material bin 71.

[0050] Referring to Figure 11 The fixing assembly 45 comprises a hinge support 451, a fixing seat 452, and a pressing block 453. The hinge support 451 and the fixing seat 452 are both fixed on the recycling box 41, and the distance between the hinge support 451 and the fixing seat 452 is consistent with the width of the sealing plate 44. The pressing block 453 is hingedly connected to the hinge support 451. During use, the sealing plate 44 is placed between the hinge support 451 and the fixing seat 452, the bottom of the sealing plate 44 blocks the corresponding recycling pipe 43, the sealing plate 44 is fixed by being pressed by the pressing block 453, and then the end of the pressing block 453 is penetrated by a latch, and the latch is fixedly connected to the fixing seat 452, so as to complete the fixing.

[0051] Specific working process:

[0052] The mineral materials mixed with block ores enter the discharging section 13 from the feeding section 11, are guided by the discharging plate 29, and then slide onto the screen 33. The qualified mineral materials directly pass through the screen 33 and are guided into the material bin 71. The block ores are blocked by the screen 33 and are guided into the crusher 83 for crushing. A small amount of mineral materials passing through the gap 6 enter the recycling box 41, are guided into the material bin 71 through the recycling pipe 43, and are automatically screened and crushed, so as to reduce the labor intensity of workers, reduce the friction of the discharging plate 29 and the conveying belt of the conveying belt machine 1, and prolong the service life.
