Description

Technical Field

[0001] This utility model relates to the field of silver flotation slag filtration technology, specifically to a belt material blocking device. Background Technology

[0002] The slag filtration process is one of the more critical steps in silver recovery. After flotation and pressure filtration of the silver concentrate in the leaching acid underflow, the remaining slurry needs to be transported to the slag filtration process for pressure filtration. The slurry is filtered by a filter press to obtain leaching residue and tailings filtrate. The obtained leaching residue is then used for zinc oxide recovery. The leaching residue is transported to the zinc oxide recovery process via a V-belt conveyor. The discharge end of the slag discharge belt conveyor below the filter press is directly opposite the V-belt conveyor to transfer the leaching residue to the V-belt conveyor for transport. In existing technology, when a filter press is unloading leaching residue, the leaching residue falls from the discharge end of the leaching conveyor belt to the V-belt conveyor with a certain initial velocity. The leaching residue undergoes an arc-shaped falling motion, which easily leads to the leaching residue spilling outside the belt of the V-belt conveyor. The spilled leaching residue causes a loss in zinc recovery, and in the long run, it will also lead to a dirty and messy environment at the leaching filtration process site. At the same time, the leaching residue tends to fall on one side of the V-belt conveyor belt, resulting in a large gravitational force of the leaching residue on one side of the V-belt conveyor belt. Summary of the Invention

[0003] This invention addresses the problem of leaching residue easily spilling off the belt or onto one side of the belt in existing technologies by providing a belt material blocking device. This device can block leaching residue falling from the discharge end of the leaching conveyor, preventing the leaching residue from moving laterally and effectively preventing it from spilling off the belt of the V-belt conveyor. It can also prevent leaching residue from falling onto one side of the V-belt conveyor.

[0004] To achieve the above objectives, the technical solution of this utility model is: a belt material blocking device, including a driven roller of a slag discharge belt conveyor and a support frame. The driven roller of the slag discharge belt conveyor is rotatably mounted on the support frame. The support frame includes two gantry frames and two support beams disposed between the two gantry frames. The support beams include two support beams that are spaced apart vertically. A V-shaped belt conveyor can pass laterally through the two gantry frames so that the slag discharge belt conveyor can transfer the leaching residue to the V-shaped belt conveyor for transportation.

[0005] The support frame is also equipped with a blocking mechanism, which includes a drive assembly and a blocking assembly. The drive assembly is located on the outer side of both support beams, and is connected to an L-shaped transmission block. The blocking assembly blocks the leaching residue falling from the discharge end of the leaching conveyor. The drive assembly can adjust the height and position of the blocking assembly to ensure it effectively blocks the falling leaching residue. The drive assembly adjusts the height and position of the blocking assembly through the L-shaped transmission block.

[0006] The blocking assembly includes a moving plate, a baffle, and buffer components. Both ends of the moving plate are connected to two L-shaped transmission blocks. Multiple buffer components are spaced apart between the moving plate and the baffle, with both ends connected to the moving plate and the baffle, respectively. The baffle blocks falling leaching residue, and the buffer components allow the baffle to move back and forth slightly. Adjusting the position of the blocking assembly prevents leaching residue from falling onto one side of the V-belt conveyor.

[0007] Furthermore, the drive assembly includes a U-shaped seat, a fixed seat, and a lead screw. The U-shaped seat is slidably mounted on the two supporting crossbeams. Two fixed seats are fixedly mounted on the outer side of the vertical part of the U-shaped seat. Bearings are provided on the fixed seats. The lead screw is rotatably connected to the fixed seats through the bearings. The movement of the U-shaped seat can drive the moving plate to move laterally through the L-shaped transmission block, thereby achieving the effect of adjusting the position of the baffle.

[0008] Furthermore, the lead screw is connected to the L-shaped transmission block, which is located between the two fixed seats. A handwheel is fixedly installed at the upper end of the lead screw. The rotation of the lead screw can drive the L-shaped transmission block to move up and down, so that the L-shaped transmission block drives the moving plate to move up and down, thereby achieving the effect of adjusting the height of the baffle.

[0009] Furthermore, a guide rail is fixedly installed on the outer side of the supporting beam, and a slider corresponding to the guide rail is fixedly installed on the inner side of the vertical part of the U-shaped seat. The slider is slidably installed on the guide rail, and the U-shaped seat can move laterally through the cooperation of the guide rail and the slider.

[0010] Furthermore, the supporting crossbeam is provided with a plurality of adjusting screw holes at intervals, and the horizontal part of the U-shaped seat is provided with adjusting bolts that cooperate with the adjusting screw holes. The U-shaped seat can be fixed by the cooperation of the adjusting bolts and adjusting screw holes, so as to facilitate the adjustment of the position of the U-shaped seat.

[0011] Furthermore, one end of the L-shaped transmission block passes through two supporting beams and has a slot at its end. Both ends of the moving plate are respectively locked in the slots of the two L-shaped transmission blocks and bolted to the L-shaped transmission blocks. The slots facilitate the connection between the moving plate and the L-shaped transmission blocks.

[0012] Furthermore, the buffer component includes a sleeve, a sliding rod, and a spring. One end of the sleeve is fixedly connected to the moving plate, one end of the sliding rod is fixedly connected to the baffle, and the other end is slidably sleeved inside the sleeve. The spring is sleeved on the sleeve and the sliding rod, and both ends of the spring are connected to the moving plate and the baffle, respectively. Through the cooperation of the sleeve and the sliding rod and under the action of the spring, the impact force of the leaching residue can cause the baffle to move back and forth slightly, so that the leaching residue can be more evenly distributed on the belt of the V-belt conveyor.

[0013] Furthermore, multiple guide rods are spaced apart on the side of the baffle near the moving plate. Guide holes are opened on the moving plate at the positions corresponding to the guide rods. One end of the guide rod passes through the guide hole and is slidably connected to the moving plate. A limit nut is provided on the guide rod. The guide rod guides the movement of the baffle, and the limit nut limits the guide rod to prevent it from detaching from the moving plate.

[0014] The beneficial effects of this utility model through the above technical solution are as follows:

[0015] This utility model has a reasonable structure and good performance. It can block the leaching residue falling from the discharge end of the slag discharge belt conveyor and prevent the leaching residue from moving laterally. It can effectively prevent the leaching residue from spilling onto the outside of the V-belt conveyor belt. At the same time, it can also prevent the leaching residue from falling onto one side of the V-belt conveyor belt.

[0016] The baffle of this utility model acts as a barrier against the leaching residue, preventing its inertial movement and ensuring it falls stably onto the V-belt conveyor belt. Through the cooperation of the sleeve and slide bar, and under the action of the spring, the impact force of the leaching residue allows the baffle to move back and forth slightly, ensuring a more even distribution of the leaching residue on the V-belt conveyor belt. Furthermore, by adjusting the lateral position of the baffle, the leaching residue can be prevented from spilling outside the V-belt conveyor belt or falling onto only one side of the belt.

[0017] This utility model can adjust the position of the baffle by adjusting the position of the U-shaped seat. The movement of the U-shaped seat can be driven by the L-shaped transmission block to move the moving plate laterally, so that the moving plate moves the baffle closer to or away from the driven roller of the slag discharge belt. The speed at which the leaching slag is conveyed by the slag discharge belt varies, and the distance and height at which the leaching slag falls are also different. The position of the baffle can be adjusted according to the distance at which the leaching slag falls.

[0018] This invention uses the rotation of a lead screw to drive an L-shaped transmission block to move up and down, which in turn drives a moving plate to move up and down. The moving plate, through a buffer, can drive a baffle to move up or down, thereby adjusting the height of the baffle and ensuring that the baffle can block the leaching residue, thus preventing the leaching residue from spilling onto the outside of the V-belt conveyor belt.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figures 1-6As shown, a conveyor belt material blocking device includes a driven roller 2 of a slag discharge conveyor and a support frame. The driven roller 2 is rotatably mounted on the support frame. The support frame includes two gantry frames 1 and two support beams disposed between the two gantry frames 1. The support beams include two vertically spaced support beams 3. In this embodiment, support frames are fixedly installed on both sides of the support frame. The support frames are welded and fixed to the outer sides of the two support beams 3. A seated bearing is installed on the top of the support frame. The roller shaft of the driven roller 2 of the slag discharge conveyor is interference-fitted with the inner ring of the seated bearing. The two ends of the support beams 3 are welded and fixed to the two gantry frames 1 respectively.

[0028] The support frame is also equipped with a blocking mechanism, which includes a drive assembly and a blocking assembly. The drive assembly is located on the outer side of both support beams, and the drive assembly is connected to an L-shaped transmission block 13. In this embodiment, the blocking mechanism blocks the leaching residue falling from the discharge end of the slag discharge conveyor. The drive assembly can drive the L-shaped transmission block 13 to move vertically and laterally.

[0029] The blocking assembly includes a moving plate 14, a baffle 15, and a buffer. The two ends of the moving plate 14 are respectively connected to two L-shaped transmission blocks 13. A plurality of buffers are arranged at intervals between the moving plate 14 and the baffle 15. The two ends of the buffers are respectively connected to the moving plate 14 and the baffle 15. In this embodiment, when the drive assembly drives the L-shaped transmission block 13 to move up and down, the two L-shaped transmission blocks 13 can drive the moving plate 14 to move up and down. The moving plate 14 synchronously drives the baffle 15 to move up and down through the buffer, thereby adjusting the height of the baffle 15. The distance between the two supporting beams 3 is the range of movement of the L-shaped transmission block 13, which is also the range for adjusting the height of the baffle 15. When the L-shaped transmission block 13 moves laterally, the two L-shaped transmission blocks 13 can drive the moving plate 14 to move laterally. The moving plate 14 synchronously drives the baffle 15 to move laterally through the buffer, thereby adjusting the lateral position of the baffle 15. When the speed of the leaching slag conveyor is different, the distance and height of the leaching slag falling are different. The position of the baffle 15 can be adjusted according to the distance of the leaching slag falling. There are four buffers between the moving plate 14 and the baffle 15. Through the action of the buffers, the impact force of the leaching slag can drive the baffle 15 to move back and forth slightly, so that the leaching slag is more evenly distributed on the belt of the V-shaped belt conveyor.

[0030] The drive assembly includes a U-shaped seat 6, fixed seats 9, and a lead screw 11. The U-shaped seat 6 is slidably mounted on two supporting crossbeams 3. Two fixed seats 9 are fixedly mounted on the outer side of the vertical portion of the U-shaped seat 6. Bearings 10 are mounted on the fixed seats 9, and the lead screw 11 is rotatably connected to the fixed seats 9 through the bearings 10. In this embodiment, the fixed seats 9 are welded and fixed to the outer side of the vertical portion of the U-shaped seat 6, and the lead screw 11 is interference-fitted with the inner rings of the bearings 10 on the two fixed seats 9.

[0031] The lead screw 11 is connected to the L-shaped transmission block 13, which is located between the two fixed seats 9. A handwheel 12 is fixedly installed at the upper end of the lead screw 11. In this embodiment, rotating the lead screw 11 causes the L-shaped transmission block 13 to move downwards or downwards on the lead screw 11, allowing the L-shaped transmission block 13 to move between the two supporting crossbeams 2. The handwheel 12 facilitates the rotation of the lead screw 11 by the operator.

[0032] A guide rail 5 is fixedly installed on the outer side of the supporting beam 3, and a slider 8 corresponding to the guide rail 5 is fixedly installed on the inner side of the vertical part of the U-shaped seat 6. The slider 8 is slidably mounted on the guide rail 5. In this embodiment, there are two sliders 8 on the inner side of the vertical part of the U-shaped seat 6. The cooperation between the slider 8 and the guide rail 5 allows the U-shaped seat 6 to slide on the two supporting beams 3, thereby facilitating the adjustment of the position of the U-shaped seat 6 on the supporting beams 3.

[0033] The supporting crossbeam 3 is provided with a plurality of adjusting screw holes 4 spaced apart, and the horizontal part of the U-shaped seat 6 is provided with adjusting bolts 7 that cooperate with the adjusting screw holes 4. In this embodiment, the U-shaped seat 6 can be fixed by cooperating with the adjusting bolts 7 and the adjusting screw holes 4. After the position of the U-shaped seat 6 is adjusted, the U-shaped seat 6 can be locked by adjusting bolts 7; when adjusting the position of the U-shaped seat 6, the locking of the U-shaped seat 6 can be released by removing adjusting bolts 7.

[0034] One end of the L-shaped transmission block 13 passes through the two supporting crossbeams 3 and has a slot at its end. The two ends of the moving plate 14 are respectively engaged in the slots of the two L-shaped transmission blocks 13 and are bolted to the L-shaped transmission blocks 13. In this embodiment, the slots match the moving plate 14, and the slots facilitate the connection between the moving plate 14 and the two L-shaped transmission blocks 13, thereby facilitating the movement of the moving plate 14 by the two L-shaped transmission blocks 13.

[0035] The buffer component includes a sleeve 16, a sliding rod 17, and a spring 18. One end of the sleeve 16 is fixedly connected to the moving plate 14. One end of the sliding rod 17 is fixedly connected to the baffle 15, and the other end is slidably fitted inside the sleeve 16. The spring 18 is fitted on the sleeve 16 and the sliding rod 17, and both ends of the spring 18 are connected to the moving plate 14 and the baffle 15, respectively. In this embodiment, the sleeve 16 is welded to the moving plate 14, and the sliding rod 17 is welded to the baffle 15. A limiting plate is installed at the end of the sliding rod 17. The diameter of the limiting plate is larger than the diameter of the opening of the sleeve 16, which is to prevent the sliding rod 17 from detaching from the sleeve 16. When the baffle 15 is subjected to the impact force of the leaching residue, the baffle 15 compresses the spring 18, and the sliding rod 17 moves into the sleeve 16. The spring 18 then feeds back the force to the baffle 15, causing the baffle 15 to move back and forth slightly.

[0036] The baffle 15 is provided with a plurality of guide rods 19 spaced apart on the side near the moving plate 14. Guide holes are provided on the moving plate 14 at positions corresponding to the guide rods 19. One end of each guide rod 19 passes through the guide hole and is slidably connected to the moving plate 14. A limit nut 20 is provided on each guide rod 19. In this embodiment, there are three guide rods 19, located between two adjacent buffer components. The guide rods 19 guide the movement of the baffle 15. When the baffle 15 moves back and forth, it causes the guide rods 19 to slide on the moving plate 14.

[0037] The working principle of this utility model is as follows: Figure 4 As shown, the V-shaped belt conveyor passes through two gantry frames 1 and is located below the blocking mechanism. When the leaching slag is conveyed by the slag discharge belt conveyor, the leaching slag falls from the discharge end of the leaching slag discharge belt conveyor and makes an arc-shaped falling motion. The leaching slag has a certain initial velocity when it falls. The height and lateral position of the baffle 15 of the blocking component are adjusted according to the height and distance of the leaching slag falling.

[0038] When adjusting the lateral position of the baffle 15, first remove the adjusting bolts 7 on the two horizontal parts of the U-shaped seat 6. After the adjusting bolts 7 on the two drive components U-shaped seats 6 are removed, move the two U-shaped seats 6 synchronously. The slider 8 on the inner side of the vertical part of the U-shaped seat 6 slides on the guide rail 5. The U-shaped seat 6 drives the lead screw 11 to move through the fixed seat 9. The lead screw 11 drives the L-shaped transmission block 13 to move synchronously. The two L-shaped transmission blocks 13 drive the moving plate 14 to move towards or away from the driven roller 2 of the slag discharge belt conveyor. The moving plate 14 drives the baffle 15 to move towards or away from the driven roller 2 of the slag discharge belt conveyor through the buffer. After adjusting the lateral position of the baffle 15, fix the two U-shaped seats 6 respectively by the cooperation of the adjusting bolts 7 and the adjusting screw holes 4.

[0039] When adjusting the height of the baffle 15, the two lead screws 11 are rotated synchronously by rotating the handwheel 12 at the top of the two drive component lead screws 11. The rotation of the lead screws 11 drives the L-shaped transmission block 13 to rise or fall. The two L-shaped transmission blocks 13 drive the moving plate 14 to rise or fall. The moving plate 14 drives the baffle 15 to rise or fall through the buffer. After the height of the baffle 15 is adjusted, the rotation of the lead screws 11 is stopped.

[0040] The leaching residue is conveyed by the leaching belt conveyor towards the baffle 15. The leaching residue falls and hits the baffle 15, which blocks the inertial motion of the leaching residue, so that the leaching residue falls stably onto the belt of the V-belt conveyor along the baffle 15, preventing the leaching residue from spilling outside the belt of the V-belt conveyor and preventing the leaching residue from falling onto one side of the belt of the V-belt conveyor. When the leaching residue hits the baffle 15, the leaching residue exerts a force on the baffle 15, the baffle 15 compresses the spring 18, the slide rod 17 moves into the sleeve 16, and the spring 18 then feeds the force back to the baffle 15, so that the baffle 15 can move back and forth with a small amplitude, so that the leaching residue is more evenly distributed on the belt of the V-belt conveyor, thereby preventing the leaching residue from falling onto one side of the belt of the V-belt conveyor.

[0041] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
