Description

Technical Field

[0001] This utility model relates to the field of lithium mica filtration technology, specifically a filtration device for lithium mica beneficiation. Background Technology

[0002] Lithium mica beneficiation is the process of separating lepidolite concentrate from lepidolite ore. It is mainly used to extract valuable metals such as lithium. In the lepidolite beneficiation process, effective filtration is the key to ensuring the quality of the mineral products and subsequent processing.

[0003] A search revealed a Chinese patent with publication number CN 217940806 U, which discloses a filtration device for lithium mica beneficiation. The key technical features are: a machine body and a filter screen installed at an inclination inside the machine body; a feed inlet is provided at the top of the machine body; a discharge outlet is provided on the side of the machine body; a vertical sliding component is installed at the high inclination end of the filter screen; and the discharge outlet is connected to the low inclination end of the filter screen.

[0004] The above solution adjusts the tilt angle of the filter screen by using a vertical sliding component to affect the rolling speed of the screened ore and improve the screening effect. However, it does not have the function of cleaning the filter screen clogging the filter holes and cannot keep the filter plate unobstructed for a long time. After a period of use, the filter screen will be clogged by the ore, which will affect the filtration efficiency and filtration quality of lepidolite minerals. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for lithium mica beneficiation to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filtration device for lithium mica beneficiation, comprising a filter box, wherein three layers of filter plates are arranged inside the filter box, and three sets of backwashing mechanisms are arranged inside the filter box corresponding to the filter plates. The backwashing mechanisms include:

[0007] A flushing pipe is located at the lower end of the filter plate, and a nozzle is connected to the upper end of the flushing pipe, with the nozzle facing the filter plate. The side end of the flushing pipe is connected to an external water pump.

[0008] A movable block is connected to the outer end of the flushing pipe, and a roller is rotatably connected to the lower end of the movable block. Constraint plates are connected to both sides of the movable block.

[0009] The track frame, the rollers of the moving block are rotatably connected within the track frame, and the constraint plate is slidably connected within the track frame;

[0010] A connecting block, wherein a threaded hole is provided in the connecting block, and the connecting block is connected to the upper end of the movable block;

[0011] A threaded rod is rotatably connected to the side end of the filter box, and a No. 1 motor is connected to the side end of the threaded rod. The threaded rod is threadedly connected inside the connecting block.

[0012] Preferably, the filter plates have filter holes that gradually decrease in size from top to bottom, and all filter plates are set at an angle.

[0013] Preferably, a filter box extends from the lower end of the filter plate, and a discharge chute is connected to the side end of the filter box corresponding to the filter plate. The discharge chute is located at the lower end of the filter plate.

[0014] Preferably, a spring is connected to the lower end of the filter plate, a vibrating block is connected to the lower end of the filter plate, and a second motor is connected to the outer end of the filter box.

[0015] Preferably, the drive end of the second motor is connected to a rotating rod, a movable rod is slidably connected inside the filter box, and a connecting rod is rotatably connected between the movable rod and the rotating rod.

[0016] Preferably, the outer end of the moving rod is connected to a collision block corresponding to the vibration block, and the collision block is located at the lower end of the vibration block.

[0017] Preferably, the upper end of the filter box is connected to a feed hopper, and the lower end of the feed hopper is located at the center end of the uppermost filter plate.

[0018] Preferably, a control panel is connected to the side of the filter box, and a drain plate is connected inside the filter box, with the drain plate located below the lowest filter plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This application incorporates a flushing pipe. External water is pumped into the flushing pipe, which then flushes the filter plate at its upper end via nozzles. A threaded rod and a moving block are also included. A motor drives the threaded rod to rotate, and the rotation of the threaded rod interacts with the connecting block. Under the constraint of the track frame, the moving block moves the flushing pipe, thus flushing the entire filter plate. This flushes away lepidolite particles and sticky substances clogging the filter plate, keeping it unobstructed and ensuring a continuous and efficient filtration process, thereby improving the overall filtration efficiency of the device.

[0021] 2. This application incorporates a vibrating block and a collision block. A second motor drives a rotating rod to rotate, which in turn drives a moving rod to reciprocate up and down via a connecting rod. This causes the collision block to continuously impact the vibrating block, which, with the assistance of a spring, vibrates the filter plate. This vibration not only effectively reduces filter plate clogging but also causes the filtered lithium mica particles to bounce on the filter plate, allowing them to quickly roll down the filter plate into the discharge hopper, thus improving the lithium mica recovery rate.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: Figures 1-6As shown, this utility model provides a technical solution for a filtration device for lepidolite beneficiation, including a filter box 1. The filter box 1 contains three layers of filter plates 2, with the filter holes gradually decreasing in size from top to bottom. This allows for graded filtration of the lepidolite slurry, significantly improving filtration efficiency and effect. All filter plates 2 are inclined, allowing the lepidolite minerals filtered out to roll down the filter plates. The lower end of the filter plates 2 extends out of the filter box 1, thus allowing the upper end... Lithium mica minerals roll off the filter plate 2 and out of the filter box 1, preventing them from falling into the lower filter plate 2 and causing interference. A discharge hopper 10 is connected to the side of the filter box 1 and the filter plate 2. The discharge hopper 10 is located at the lower end of the filter plate 2 and is used to collect the lithium mica minerals that roll off the filter plate 2. The discharge hopper 10 is also inclined so that the lithium mica minerals can slide down the discharge hopper 10. A collection box is placed on the side of the discharge hopper 10 to collect the lithium mica minerals directly.

[0031] The filter box 1 is equipped with three sets of backwashing mechanisms corresponding to the filter plates 2. These mechanisms use water flow to flush the filter plates 2 from the bottom, removing minerals clogging the filter holes. The flushed minerals fall back onto the filter plates 2, and some may roll along them. The backwashing mechanism includes a flushing pipe 3, a moving block 4, a track frame 6, a connecting block 7, and a threaded rod 8. The flushing pipe 3 is located at the bottom of the filter plates 2, and a nozzle is connected to its upper end, facing the filter plates 2. The water flow from the nozzle flushes the filter plates 2. A gap is left between the filter plates 2 and the nozzle to prevent the filter plates 2 from contacting or colliding with the nozzle during vibration. The side of the flushing pipe 3 is connected to an external water pump, which draws external water to fill the flushing pipe 3. The movable block 4 is connected to the outer end of the flushing pipe 3. A roller is rotatably connected to the lower end of the movable block 4. The roller is rotatably connected to the track frame 6, which facilitates the movement of the movable block 4 within the track frame 6. Constraint plates 5 are connected to both sides of the movable block 4. The constraint plates 5 are slidably connected within the track frame 6. The constraint plates 5 are used to constrain the movable block 4, so that it can move smoothly within the track frame 6 without rotating. A threaded hole is opened in the connecting block 7. The connecting block 7 is connected to the upper end of the movable block 4. A threaded rod 8 is rotatably connected to the side end of the filter box 1. A No. 1 motor 9 is connected to the side end of the threaded rod 8. The threaded rod 8 is threadedly connected within the connecting block 7. When the No. 1 motor 9 is started, it will drive the threaded rod 8 to rotate. The rotation of the threaded rod 8 interacts with the connecting block 7, which will enable the movable block 4 to move within the track frame 6.

[0032] A second motor 13 is connected to the outer end of the filter box 1. A rotating rod 14 is connected to the drive end of the second motor 13. A moving rod 15 is slidably connected inside the filter box 1. The moving rod 15 can only move up and down. A connecting rod 16 is rotatably connected between the moving rod 15 and the rotating rod 14. The rotating rod 14, the moving rod 15, and the connecting rod 16 are all located inside the filter box 1. A collision block 17 is connected to the outer end of the moving rod 15 and the vibrating block 12. When the second motor 13 is started, it will drive the moving rod 15 to move up and down reciprocally through the rotating rod 14 and the connecting rod 16, thereby driving the collision block 17 to move up and down reciprocally. A spring 11 is connected to the lower end of the filter plate 2. A vibrating block 12 is connected to the lower end of the filter plate 2. The collision block 17 is located at the lower end of the vibrating block 12. The collision block 17 can collide with the vibrating block 12. With the assistance of the spring 11, the filter plate 2 can vibrate continuously.

[0033] The upper end of the filter box 1 is connected to the feed hopper 18, and the lower end of the feed hopper 18 is located at the center end of the uppermost filter plate 2. The side end of the filter box 1 is connected to the control panel, which is used to control the operation of the device. The filter box 1 is connected to the drain plate 19, which is located at the lower end of the lowest filter plate 2. The filtered slurry flows onto the drain plate 19. The drain plate 19 is inclined so that the slurry can be discharged from the filter box 1.

[0034] Working principle: Motor 13 starts, driving the moving rod 15 up and down via the rotating rod 14 and connecting rod 16. This causes the collision block 17 to move up and down. When the collision block 17 reaches its highest point, it collides with the vibrating block 12. With the assistance of the spring 11, the filter plate 2 vibrates continuously. Lithium mica slurry is added to the filter box 1 through the feed hopper 18, passing through three layers of filter plates 2. The minerals filtered by the filter plates 2 bounce on them under the vibration, allowing them to quickly roll down the filter plates 2 into the discharge hopper 10. The control panel periodically activates the backwashing mechanism, and external water is supplied through... The water pump injects water into the flushing pipe 3, which flushes the filter plate 2 at its upper end through the nozzle. The No. 1 motor 9 starts and drives the threaded rod 8 to rotate. The rotation of the threaded rod 8 interacts with the connecting block 7. Under the constraint of the constraint plate 5 and the track frame 6, the moving block 4 can move the flushing pipe 3, thereby flushing the entire filter plate 2 and flushing out the minerals that are blocking the filter holes. The flushed minerals will fall back onto the filter plate 2. Due to the vibration of the filter plate 2, the minerals are less likely to get stuck in the filter plate 2 and will bounce and roll down along the filter plate 2, thus keeping the filter plate 2 unobstructed and enabling the filtration process to continue to be carried out efficiently.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
