Description

Technical Field

[0001] This invention relates to the field of lead-zinc ore processing technology, and in particular to an ore washing device for lead-zinc ore mining. Background Technology

[0002] In the process of lead-zinc ore mining, ore cleaning is a crucial step. Its main purpose is to remove the mud, dust and other impurities attached to the ore surface to improve the efficiency of subsequent beneficiation operations and product quality. However, existing cleaning equipment and technology still have some shortcomings, especially when dealing with pits and depressions on the ore surface, where it is often difficult to completely remove dirt.

[0003] Currently, most ore washing equipment relies on hydraulic spraying to wash the ore, using high-pressure water flow or spray systems to wash away loose impurities on the ore surface. However, this method also has obvious limitations: because lead-zinc ore usually has an irregular shape and many pits and depressions on the surface, these areas are prone to accumulating fine particles of mud and stubborn stains, which cannot be completely removed by water flow alone. If the mud, dust and other impurities on the ore surface are not cleaned properly, the grade of the final concentrate product may decrease, because the presence of impurities will dilute the proportion of useful minerals. Summary of the Invention

[0004] In view of this, the present invention provides an ore cleaning device for lead-zinc ore mining, which can solve the shortcomings of traditional ore cleaning equipment that usually relies on water spraying, making it difficult to remove stubborn dirt in pits and depressions on the ore surface.

The filter plate is used to separate impurities and ore for discharge.

[0011] In a preferred embodiment of the present invention, a protective plate is also included. The protective plate is provided inside the brushing cylinder and is used to cover the rotating shaft.

[0012] In a preferred embodiment of the present invention, an impact mechanism is further included. The impact mechanism includes a connecting frame and an impact plate.

The end is provided with strip-shaped holes at intervals, which are adapted to the bristles 10; four friction rollers 14 are rotatably arranged on the arc plate 13 at intervals, and the four friction rollers 14 are distributed in front and behind; a driving mechanism is provided on the arc plate 13, which is used to drive the friction rollers 14 to rotate, so that the friction rollers 14 drive the ore to turn over through friction; a spray pipe 16 is provided on the outside of the brushing cylinder 9, which is used to spray water towards the inside of the brushing cylinder 9; a discharge mechanism is installed on the left side of the brushing cylinder 9, which is used to separate the ore and impurities for discharge.

[0030] See Figure 2 As shown, the adjustment mechanism includes a connecting rod 301, an electric push rod 302, and a ring plate 303; the connecting rod 301 is symmetrically arranged on the front and back sides of the sleeve 2; the electric push rod 302 is symmetrically arranged on the front and back sides of the upper right side of the support frame 1; the telescopic rods of the two electric push rods 302 are connected to the ring plate 303, and the two connecting rods 301 are respectively located in the two ring plates 303.

[0031] See Figure 2 and Figure 3As shown, the rotating mechanism includes a first motor 501, a first gear 502, and a gear ring 503; the first motor 501 is installed on the top left side of the sleeve 2; the first gear 502 is connected to the output shaft of the first motor 501; the gear ring 503 is connected to the outer left side of the filter cartridge 4, and the first gear 502 meshes with the gear ring 503.

[0032] See Figures 2-5 As shown, the water spraying mechanism includes a connecting plate 701, a water spray pipe 702, a water receiving pipe 703, a connecting cylinder 704, and a turbine 705; the connecting plate 701 is connected to the top left side of the sleeve 2; the water spray pipe 702 is rotatably mounted on the connecting plate 701, and the water spray pipe 702 is located inside the filter cartridge 4; the water receiving pipe 703 is installed on the connecting plate 701; the left end of the water spray pipe 702 is connected to the connecting cylinder 704, and the connecting cylinder 704 is rotatably connected to the water receiving pipe 703; the turbine 705 is connected inside the connecting cylinder 704.

[0033] like Figure 8 As shown, the drive mechanism includes a second gear 1501 and a third motor 1502; the left ends of the four friction rollers 14 are all provided with second gears 1501, and the second gears 1501 on two adjacent friction rollers 14 mesh with each other; the lower left side of the arc plate 13 is equipped with a third motor 1502, and the output shaft of the third motor 1502 is connected to the left end of the last friction roller 14.

[0034] like Figure 9 and Figure 10 As shown, the discharge mechanism includes a discharge cylinder 1701 and a filter plate 1702; the discharge cylinder 1701 is installed on the left side of the washing cylinder 9; the filter plate 1702 is provided at the bottom of the discharge cylinder 1701, and the filter plate 1702 is used to separate impurities and ore for discharge.

[0035] In use, the electric push rod 302 first drives the ring plate 303 to move up or down, causing the ring plate 303 to rotate the sleeve 2 via the connecting rod 301. This allows the inclination of the sleeve 2, filter cylinder 4, and feeding frame 6 to be adjusted as needed, thereby regulating the rolling speed of the ore inside the filter cylinder 4. After adjustment, the high-pressure water source is connected to the water inlet pipe 703 and the spray pipe 16, allowing the high-pressure water to enter the spray pipe 702 through the connecting cylinder 704. This causes the spray pipe 702 to spray clean water towards the inside of the filter cylinder 4. During this process, when the clean water comes into contact with the turbine 705 inside the connecting cylinder 704, the clean water will squeeze the turbine 705 to rotate, thereby driving the connecting cylinder 704 and the spray pipe 702 to rotate, thus causing the spray pipe 702 to rotate and spray water simultaneously. Preferably, the rotation direction of the water spray pipe 702 is opposite to that of the filter cartridge 4, making the high-pressure water source more thorough in cleaning the surface of the ore. After the clean water in the pipe enters the spray pipe 16, the spray pipe 16 will spray the clean water towards the inside of the scrubbing cylinder 9. Then, the first motor 501 is started, causing the first motor 501 to drive the first gear 502 to rotate, thereby causing the first gear 502 to drive the gear ring 503 and the filter cartridge 4 to rotate. Subsequently, the second motor 11 and the third motor 1502 are started, causing the second motor 11 to drive the rotating shaft 12 to rotate (the rotating shaft 12 rotates clockwise when viewed from left to right), thereby causing the rotating shaft 12 to drive the arc plate 13 to rotate. At the same time, the third motor 1502 drives the friction roller 14 through the transmission of the second gear 1501. The ore is then gradually poured into the feeding frame 6, causing it to roll to the left under gravity. As the ore rolls into the filter cylinder 4, it continues to roll to the left along the bottom of the filter cylinder 4. The rotating filter cylinder 4 causes the ore to tumble, and the water sprayed from the water pipe 702 washes the tumbled ore, removing impurities. The washed-off impurities and the washing water pass through the filter cylinder 4 and are discharged from the discharge port at the bottom of the sleeve 2. After the washed ore rolls to the left from the bottom of the filter cylinder 4, it falls into the bottom of the washing cylinder 9. The tilted state of the washing cylinder 9 causes the ore to roll to the left along the bottom of the washing cylinder 9. When the rotating shaft 12 drives the arc plate 13... When the ore rotates to contact the bottom of the brushing cylinder 9, the arc-shaped plate 13 will move the ore along the inner wall of the brushing cylinder 9. When the ore contacts the friction roller 14, the friction roller 14 will cause the ore to flip due to friction. After the arc-shaped plate 13 moves the ore past its highest point, the ore will roll down the surface of the arc-shaped plate 13 due to gravity until it falls to the bottom of the brushing cylinder 9. Because the brushing cylinder 9 is tilted, the position of the ore after falling can be offset to the lower left compared to its initial position. By repeating this process, the ore can gradually move to the lower left within the brushing cylinder 9. When the arc-shaped plate 13 moves the ore to contact the bristles 10 on the inner wall of the brushing cylinder 9, the bristles 10 will brush the surface of the ore. It should be noted that...The bristles 10 are made of a rigid material, allowing them to penetrate into the pits and depressions on the ore surface for thorough scrubbing, thus removing stubborn dirt from these areas. The friction roller 14 rotates the ore, ensuring all surfaces of the ore come into contact with the bristles 10, providing a comprehensive scrubbing experience. During the scrubbing process, water sprayed from the spray pipe 16 into the scrubbing cylinder 9 washes away stubborn dirt, allowing it to be discharged with the water flow through the bottom left of the scrubbing cylinder 9. When the water flows to the discharge cylinder 1701 from the lower left, stubborn dirt will fall out with the water flow through the filter plate 1702, thus allowing the stubborn dirt and water to be discharged. After the ore has been washed inside the washing cylinder 9, it will move from the inside of the washing cylinder 9 to the lower left into the discharge cylinder 1701, and then slide down from the top of the filter plate 1702 to the lower left for discharge. In this way, the surface of the ore can be cleaned, and stubborn dirt in the pits and depressions on the ore surface can be removed. Furthermore, the cleaned ore and the removed dirt can be discharged separately, allowing workers to perform subsequent processing on the cleaned ore. Afterwards, by repeatedly pouring subsequent batches of ore into the feeding frame 6, the batches of ore can be continuously cleaned. After all the ore has been cleaned, the second motor 11 and the third motor 1502 are turned off, and the high-pressure water source is stopped from being introduced into the water inlet pipe 703 and the spray pipe 16.

[0036] like Figure 9 and Figure 10 As shown, it also includes a protective plate 18; a protective plate 18 is provided on the upper right side of the inner side of the brushing cylinder 9. The protective plate 18 is located directly above the rotating shaft 12. The protective plate 18 is used to shield the rotating shaft 12, and the top of the protective plate 18 is a slope, which is used to guide the ore to fall to the front and rear sides.

[0037] By setting up the protective plate 18, when the washed ore falls into the washing cylinder 9 and comes into contact with the inclined surface of the protective plate 18, the protective plate 18 will use the inclined surface to guide the ore falling into the washing cylinder 9 to the front and back sides, so as to prevent the ore from hitting the rotating shaft 12 when it falls down, thereby protecting the rotating shaft 12 and extending the service life of the rotating shaft 12.

[0038] like Figure 11 and 12 As shown, it also includes an impact mechanism, which includes a connecting frame 19 and an impact plate 20; the connecting frame 19 is connected to the inner side of the feeding frame 6, and impact plates 20 are spaced apart inside the connecting frame 19. The impact plates 20 are inclined and are used to shake off impurities on the ore.

[0039] By setting up an impact mechanism, when the ore is poured into the feeding frame 6, the ore will fall into the connecting frame 19. When the ore falls to contact the impact plate 20, the impact plate 20 will collide with the ore, thereby causing the ore to vibrate and shake off the impurities on the ore, thus separating the ore from the impurities attached to its surface, so that the ore surface can be cleaned later. After the ore and the impact plate 20 have completed their collision, the ore and the shaken-off impurities will slide down from the impact plate 20 together.
