Description

Technical Field

[0001] The invention relates to the technical field of ore cleaning, and in particular to a water-saving ore soil separator. Background Art

[0002] As global resource development continues, the mining technology of mineral resources is also constantly developing and improving. In the process of ore mining, the ore is often mixed with a large amount of soil, which not only increases the transportation cost, but also causes increased equipment wear in the subsequent processing process, affecting product quality. Therefore, after ore mining, it is necessary to effectively separate the soil from the ore.

[0003] At present, ore and soil are usually separated by an ore-soil separator. The existing ore-soil separator uses a plurality of rollers to form a conveyor line to convey ore, and a spray device is arranged above the roller to wash the ore on the roller, so that the soil on the surface of the ore is discharged from the gap between the rollers with the water flow, thereby achieving the purpose of separation. However, this separation method has some shortcomings: first, when the ore is conveyed on the roller, the bottom of the ore at the bottom will be close to the surface of the roller, making it difficult for the spray structure to effectively remove the soil at the bottom of the ore, thereby affecting the separation effect; in addition, in the process of separating ore from soil, since a large amount of water is needed to wash the ore, this separation method also has the problem of water resource waste. Summary of the invention

[0004] In view of this, the present invention provides a water-saving ore-soil separator, which can overcome the shortcomings of the existing ore-soil separator in which the bottom of the ore at the bottom will be close to the surface of the drum when in use, making the soil at the bottom of the ore difficult to clean, resulting in poor separation effect, and a large amount of water resources required in the entire separation process.

[0005] Technical solution: A water-saving ore soil separator includes a frame and a roller screen, the roller screen is installed on the frame, and also includes a controller, a drain valve, a conveyor, a connecting frame, a baffle, a baffle, a water storage frame, a water pump I, a connecting pipe and a filtering mechanism. The controller is installed on the side of the frame, the drain valve is connected to the side of the frame, the conveyor is installed on the frame, the connecting frame is evenly connected to the conveyor belt of the conveyor, the baffle is connected to the inside of the connecting frame at intervals, the baffle and the water storage frame are connected to the inner wall of the frame, the water pump I is installed at intervals on the inner bottom wall of the frame, the connecting pipe connects the water storage frame and the water outlet of the water pump I, and the filtering mechanism is used to filter the soil inside the frame.

[0006] In one embodiment, the filtering mechanism includes a conical frame, an arcuate filter plate and a discharge assembly.

The fixed frame is connected to the side of the frame. The inclined tube is symmetrically connected to the fixed frame, and the end of the inclined tube passes through the side of the frame. Two vertical tubes are connected to the inclined tubes, and one of the vertical tubes is connected to the through hole. The screw feeder is installed inside the inclined tube.

[0008] In one of the embodiments, the height of the upper end of the other vertical tube is higher than the height of the top surface of the frame.

[0009] In one of the embodiments, filter holes are spaced circumferentially around the end of the inclined tube.

[0010] In one of the embodiments, it also includes an electric push rod, a mounting frame, a spray pipe, a water pump II and a hose.

[0025] Embodiment: A water-saving ore soil separator, such as Figure 1-Figure 5 As shown, it includes a frame 1, a roller screen 2, a controller 3, a drain valve 4, a conveyor 5, a connecting frame 6, a baffle 7, a baffle 8, a water storage frame 9, a water pump Ⅰ10, a connecting pipe 11 and a filtering mechanism. The upper left side and the upper right side of the frame 1 are both inclined surfaces, which are convenient for loading and unloading of ore. The roller screen 2 is composed of a motor, a screen shaft, a screen plate and a pulley assembly. The motor is installed on the upper left front side of the frame 1. Multiple screen shafts are rotatably connected at intervals on the upper left side of the frame 1, and the front end of the leftmost screen shaft is connected to the output shaft of the motor. Each screen shaft is connected at intervals from front to back. There are multiple sieve plates, and the transmission is carried out between two adjacent sieve shafts through a pulley assembly. The shape of the sieve plate is square, and the angles of the sieve plates on the two adjacent sieve shafts differ by forty-five degrees, so that when the roller screen 2 transports the ore to the right, the ore will vibrate due to the height difference between the sieve plates, so that its surface can be adhered to the soil and shaken off. A controller 3 is installed on the right front side of the frame 1, and a drain valve 4 is installed on the lower right side of the frame 1 to discharge the waste water in the frame 1. A conveyor 5 is installed on the right upper side of the frame 1. The conveyor 5 is inclined and is used to wash the The finished ore is transported to the upper right outside the frame 1, and the conveyor belt of the conveyor 5 is circumferentially spaced with a straight hole to prevent the conveyor 5 from transporting the water in the frame 1 out. The conveyor belt of the conveyor 5 is also circumferentially spaced with connecting frames 6, and each connecting frame 6 is spaced with three blocking rods 7, and the blocking rod 7 is used to block the ore in the connecting frame 6. Both sides of the connecting frame 6 are open-type designs so that the water in the connecting frame 6 can return to the frame 1 through the gaps between the blocking rods 7. A baffle 8 is connected to the upper left side of the frame 1, and the baffle 8 is inclined. 8 cooperates with the left side of the inner wall of the frame 1 to guide the ore placed in the frame 1. A water storage frame 9 is connected to the middle of the upper part of the frame 1. The water storage frame 9 is located above the roller screen 2 and the conveyor 5. Notches are opened on the upper parts of the left and right sides of the water storage frame 9 so that the water in the water storage frame 9 can flow downward into the frame 1 through the notches. Four water pumps Ⅰ10 are installed on the bottom wall of the frame 1 at intervals. Connecting pipes 11 are connected between the water outlets of the four water pumps Ⅰ10 and the water storage frame 9. The connecting pipes 11 run through the front side of the frame 1. The filtering mechanism is used to filter the soil inside the frame 1.

[0026] like Figure 3-Figure 5As shown, the filtering mechanism includes a conical frame 12, an arc filter plate 13 and a discharge assembly. The conical frame 12 is connected to the lower inner part of the frame 1. The width of the conical frame 12 gradually decreases from top to bottom, and the bottom surface of the conical frame 12 is connected to the arc filter plate 13. The arc filter plate 13 is located above the water pump Ⅰ10. The bottom surface of the arc filter plate 13 is symmetrically provided with through holes 1301. The discharge assembly is used to discharge the soil filtered by the arc filter plate 13 out of the frame 1; the discharge assembly includes a driving motor 14, a bidirectional screw rod 15, a fixing frame 16, an inclined pipe 17, a vertical pipe 18 and a screw feeder 19. The driving motor 14 is installed at the lower left side of the frame 1. The conical frame 12 is internally connected to the bidirectional screw rod 15 for rotation. The left end of the bidirectional screw rod 15 rotates and passes through the left side of the frame 1, and the left end of the bidirectional screw rod 15 is connected to the output shaft of the driving motor 14. A fixing frame 16 is connected to the rear side of the frame 1, and an inclined tube 17 is symmetrically connected to the fixing frame 16. The inclined tube 17 is inclinedly arranged with the front lower and the rear higher, and the lower end of the inclined tube 17 passes through the rear side of the frame 1. The lower end of the inclined tube 17 is also circumferentially spaced with filter holes 20. The upper and lower parts of the inclined tube 17 are connected to vertical tubes 18. The upper ends of the vertical tubes 18 on the lower side are connected to the through holes 1301, and the upper ends of the vertical tubes 18 on the upper side are higher than the top surface height of the frame 1 to prevent water in the frame 1 from being discharged outward through the inclined tubes 17 and the vertical tubes 18. The screw feeder 19 is installed inside the inclined tube 17.

[0027] like Figure 6-Figure 8 As shown, it also includes an electric push rod 21, a mounting frame 22, a spray pipe 23, a water pump II 24, a hose 25, a rotating swing rod 26 and an angle sensor 27. Four electric push rods 21 are connected to the bottom surface of the water storage frame 9 at intervals. The four electric push rods 21 are distributed in a rectangular shape, and the telescopic rods of the electric push rods 21 slide through the bottom surface of the water storage frame 9. The mounting frame 22 is connected between the telescopic rods of the four electric push rods 21. The mounting frame 22 is located between the water storage frame 9 and the roller screen 2. The spray pipe 23 is connected to the mounting frame 22. A water pump II 24 is installed in the middle of the water storage frame 9, and the pump II 24 is installed in the middle of the water storage frame 9. A hose 25 is connected between the water outlet of the water pump II 24 and the middle part of the spray pipe 23. A rotating swing arm 26 is rotatably connected to the upper left side of the interior of the frame 1. The rotating swing arm 26 is located on the left side of the spray pipe 23. The rotating swing arm 26 is U-shaped, and the inner diameter of the rotating swing arm 26 is larger than the width of the spray pipe 23 so that the spray pipe 23 will not block the swing of the rotating swing arm 26. The front end of the rotating shaft of the rotating swing arm 26 rotates and passes through the front side of the frame 1. An angle sensor 27 is installed on the upper left part of the front side of the frame 1, and the rotating shaft of the angle sensor 27 is connected to the front end of the rotating shaft of the rotating swing arm 26.

[0028] First, add a proper amount of water into the frame 1, so that the liquid level in the frame 1 is slightly lower than the height of the bottom surface of the baffle 8. At this time, the entire roller screen 2 will be immersed in the water in the frame 1, and then add a proper amount of water into the water storage frame 9, so that the liquid level in the water storage frame 9 is flush with the height of its notch; then the controller 3 controls the water pump Ⅰ10 to start working, and the water pump Ⅰ10 will extract the water in the frame 1 and transport the water to the water storage frame 9 through the connecting pipe 11, and the water in the water storage frame 9 will overflow to the left and right sides through the notch on it, and fall down into the frame 1 for replenishment, so that the water can be stored in the frame 1 and the water storage frame 9 forms a water cycle, and can make the water in the frame 1 produce the effect of flowing downward; then the ore with soil can be poured in from the upper left side of the frame 1, the baffle 8 can limit the ore and guide it to prevent the ore from entering the water storage frame 9, so that the ore can accurately fall down to the left side of the top surface of the roller screen 2, and at the same time, the roller screen 2, the conveyor 5, the drive motor 14, the screw feeder 19 and the water pump II 24 can be controlled by the controller 3 to start working, and the roller screen 2 can transport the ore on it to the right. Since the ore and the soil are soaked in water, the adhesion of the soil can be reduced, and the roller screen 2 can make the ore produce The water pump II 24 can transport the water in the water storage frame 9 to the spray pipe 23 through the hose 25, so that the spray pipe 23 can spray water downward to wash the ore on the roller screen 2. At this time, the ore is not far below the water surface. Although the water sprayed by the spray pipe 23 will be subject to certain resistance from the water surface, it will be easier to separate from the ore after the adhesion of the soil is reduced, so it does not affect the overall cleaning effect. In this way, the ore can be fully cleaned and the cleaning effect is improved. At the same time, since the water in the frame 1 has the effect of flowing downward, it can drive the soil in the water to move downward, and the cleaned ore will fall to the conveyor 5. On, the conveyor 5 can drive the connecting frame 6 and the baffle 7 to rotate, and the connecting frame 6 and the baffle 7 can cooperate to transport the ore on the conveyor 5 to the upper right to the outside of the frame 1, which is convenient for manual unified collection. Since the water and soil in the frame 1 are mixed together, there may be soil floating on the water surface in the frame 1, resulting in the ore on the conveyor 5 When leaving the water surface, there may be soil re-attached to the surface of the ore. The water flowing downward from the notch on the right side of the water storage frame 9 will first fall onto the conveyor 5, and then flow downward along the conveyor 5 to the frame 1, so the ore on the conveyor 5 can be rinsed twice to ensure the cleaning effect of the ore;During the ore cleaning process, the mud will fall down into the conical frame 12 with the water flow, the arc filter plate 13 can filter the mud, and the driving motor 14 can drive the bidirectional screw rod 15 to rotate, and the bidirectional screw rod 15 can move the mud in the arc filter plate 13 to the left and right sides, so that the mud can pass through the through hole 1301 and the vertical pipe 18 at the lower side into the inclined pipe 17, and the mud will squeeze the water in the inclined pipe 17 to flow into the frame 1 through the filter hole 20, thereby preventing the water in the inclined pipe 17 from flowing upward and The soil in the lower vertical pipe 18 is flushed upward to ensure that the soil can smoothly enter the inclined pipe 17, thereby preventing the arc filter plate 13 from being blocked by the soil. At the same time, the spiral feeder 19 can timely transport the soil in the inclined pipe 17 upward to the upper vertical pipe 18, and discharge it through the upper vertical pipe 18, which is convenient for subsequent unified processing by manual labor; when the ore volume is large, the ore will contact the lower part of the rotating swing rod 26 when it is transported to the right on the roller screen 2, and squeeze the rotating swing rod 26 to swing to the right, and the rotating swing rod 26 can The output shaft of the angle sensor 27 is driven to rotate, and the angle sensor 27 will send a signal. After receiving the signal, the controller 3 will control the telescopic rod of the electric push rod 21 to shorten, so as to drive the mounting frame 22 and the spray pipe 23 to rise. In this way, the distance between the spray pipe 23 and the roller screen 2 can be increased to prevent the ore from colliding with the spray pipe 23, which can not only ensure that the spray pipe 23 is not damaged, but also ensure the normal transportation of the ore. The larger the volume of the ore, the larger the swing angle of the rotating swing rod 26, and the higher the rising height of the spray pipe 23. When the ore is separated from the lower part of the rotating swing rod 26, the rotating swing rod 26 will automatically swing back to the vertical state due to gravity. The rotating swing rod 26 can drive the output shaft of the angle sensor 27 to reverse. At this time, the angle sensor 27 does not send a signal, and the angle sensor 27 only records the maximum angle change value detected by it. When processing the next batch of ore, the telescopic rod of the electric push rod 21 can be controlled by the controller 3 to extend, so as to drive the mounting frame 22 and the spray pipe 23 to descend to the original position. ;
