Description

Technical Field

[0001] This invention relates to a graphite tailings feeding device and its usage method, belonging to the field of tailings treatment equipment. Background Technology

[0002] The accumulation of graphite tailings occupies a large amount of agricultural and forestry land. The exposed, silty tailings powder easily generates dust storms and even sandstorms during windy conditions. Furthermore, the mineral processing reagents remaining in the graphite tailings produce harmful gases and acidic water, directly causing serious pollution to the atmosphere and soil, leading to soil pollution, land degradation, and vegetation destruction. There are three main ways to comprehensively utilize graphite waste tailings powder: 1. Recovering valuable minerals from graphite tailings sand; 2. Using graphite tailings sand to produce other mineral materials; 3. Using graphite tailings sand to produce building materials. Among these methods, the production of building materials from tailings requires adding raw materials in a specific ratio. While such equipment exists on the market, it requires constant starting and stopping of the conveyor belt, wasting time and reducing efficiency; therefore, improvement is necessary. Summary of the Invention

[0006] A method of using a graphite tailings feeding device, the method comprising the following steps:

[0007] Step 1: The tailings are fed into the limiting device through the gap between the limiting device and the partition plate via the conveyor belt, so that the tailings enter the storage tank located at the lower end of the limiting device.

[0008] Step 2: After the weight of the storage bucket increases to the predetermined weight, push the slide bar to compress the spring and slide it downwards;

[0009] Step 3: The rotation is caused by the arc-shaped rod limiting the movement, which drives another storage bucket to the lower end of the limiting device, thus achieving continuous fixed weight feeding.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the present invention not only eliminates the need for the start and stop of the conveyor belt to achieve the predetermined weight of tailings transfer, but also eliminates the need for electronic components in harsh working environments such as mines and outdoors. This eliminates the need to consider the dust generated during tailings transfer falling on electronic components or electric equipment, affecting heat dissipation, and also saves maintenance costs.

[0024] Specific implementation method one: as follows Figure 1-12 As shown, this embodiment describes a graphite tailings guiding device, including a shell 1, a movable device 2, a transmission device 3, and a limiting device 4; the movable device 2, which can move up and down, is provided inside the shell 1; the transmission device 3 is slidably engaged with the shell 1, and a part of the transmission device 3 is located below the movable device 2, while the other part of the transmission device 3 is located above the movable device 2; the limiting device 4 is fixedly connected inside the shell 1 and is located at the upper end of the movable device 2.

[0026] The movable device 2 includes a storage tank 21; the storage tank 21 is arc-shaped, and there are two storage tanks 21. Each storage tank 21 has a groove 22 on its outer arc surface and a discharge port 23 on its inner arc surface. A connecting rod 26 is fixedly connected to the bottom end of the storage tank 21. A bidirectional telescopic rod 27 is hinged to the lower end of the connecting rod 26. The center of the bidirectional telescopic rod 27 has a circular hole 28 that fits onto the shaft I 117. The bidirectional telescopic rod 27 slides in conjunction with the through hole 116. The central angle corresponding to the storage tank 21 is 140°-180°.

[0027] When the storage tank 21 located at a high position moves downward, it comes into contact with the arc-shaped rod 13, causing the storage tank 21 to move downward under the action of gravity and also to be displaced in the horizontal direction.

[0028] A connecting cylinder 14 is fixedly connected to the outer side of the cylinder 11; a sliding rod 16 is provided inside the connecting cylinder 14 and slides therewith; the sliding rod 16 passes through the cylinder 11, and one end of the sliding rod 16 inside the cylinder 11 is set as an inclined surface; a spring 15 is fixedly connected between the sliding rod 16 and the inner wall of the connecting cylinder 14; the sliding rod 16 slides in conjunction with the sliding groove 22.

[0030] The magnets 25 on the two storage barrels 21 have different magnetic properties; a magnetic strip is fixedly connected to the side of the rotating rod 114, and the magnetic strip has the same magnetic properties as the nearest magnet 25; when the distance between the rotating rod 114 and the two magnets 25 is the same, the forces on both sides of the rotating rod 114 are different.

[0031] The transmission device 3 includes a transmission rod I 31, a connecting rod 32, a transmission rod II 33, a partition plate 34, and an elastic telescopic rod 35; the side of the cylinder 11 is provided with a vertical track 12 that passes through the cylinder 11; the crossbar 19 is provided with a through hole 18; the connecting rod 32 is U-shaped, one end of the connecting rod 32 is slidably engaged with the track 12, and the transmission rod I 31 is fixedly connected to its upper end surface; the lower end surface of the other end of the connecting rod 32 is fixedly connected to the transmission rod II 33, which is slidably engaged with the through hole 18, and the lower end of the transmission rod II 33 is fixedly connected to the partition plate 34; one end of the elastic telescopic rod 35 is fixedly connected to the connecting rod 32, and the other end of the elastic telescopic rod 35 is fixedly connected to the upper end of the crossbar 19; the partition plate 34 is an upwardly convex arc shape, and the vertical projection area of ​​the partition plate 34 is the same as the vertical projection area of ​​the storage tank 21.

[0032] The limiting device 4 includes two side baffles 41 and two arc-shaped baffles 42; the two ends of the opposite surfaces of the two arc-shaped baffles 42 are respectively fixedly connected to the side baffles 41, and one of the arc-shaped baffles 42 is fixedly connected to the inner wall of the cylinder 11; the partition plate 34 is slidably engaged with the limiting device 4, and the projected area of ​​the partition plate 34 in the vertical direction is equal to the area of ​​the bottom opening of the limiting device 4.

[0033] The central angles corresponding to the storage tank 21 and the partition plate 34 are equal to the central angles corresponding to the bottom of the limiting device 4.

[0034] A method of using a graphite tailings feeding device, the method comprising the following steps:

[0035] Step 1: The tailings are fed into the limiting device 4 through the gap between the limiting device 4 and the partition plate 34 by the conveyor belt, so that the tailings enter the storage tank 21 located at the lower end of the limiting device 4.

[0036] Step 2: After the weight of storage tank 21 increases to the predetermined weight, push slide bar 16 to compress spring 15 and slide downwards;

[0037] Step 3: The rotation is limited by the arc rod 13, which drives another storage bucket 21 to move to the lower end of the limiting device 4, so as to achieve continuous fixed weight feeding.

[0038] The working principle of this invention is as follows: When using this device, the tailings are fed into the limiting device 4 through the gap between the limiting device 4 and the partition plate 34 via the conveyor belt, so that the tailings pass through the limiting device 4 and enter the storage tank 21 located at the lower end of the limiting device 4.

[0039] After the weight of the storage tank 21 increases to the predetermined weight, the gravity on the storage tank 21 is greater than the elastic force of the spring 15, which pushes the slide rod 16 to move into the connecting cylinder 14 and compresses the spring 15, so that the storage tank 21 can slide downward.

[0040] As the storage tank 21 slides downwards, it contacts the transmission rod I 31, pushing it downwards. This causes the transmission rod I 31 to move the connecting rod 32, transmission rod II 33, and partition plate 34 downwards together, compressing the elastic telescopic rod 35. The partition plate 34 moves downwards to the lower middle part of the limiting device 4. The upper middle part of the side baffle 41 is set as an inclined plate to catch more falling tailings, while the lower middle part of the side baffle 41 is set as a vertical plate, so that the vertical plate fits against the two sides of the partition plate 34 to form a collection container. The two sides of the partition plate 34 contact the vertical plate portions of the two side baffles 41. When the partition plate 34 moves to the limiting device... After the lower middle part of the side plate of the 4th container contacts the vertical plate, the tailings conveyed by the conveyor belt fall onto the upper end of the partition plate 34 and are temporarily stored in the container formed by the limiting device 4 and the partition plate 34. As the storage tank 21 moves downwards, it contacts the arc-shaped rod 13. Since the arc-shaped rod 13 is angled, and the storage tank 21 is also close to the inner wall of the cylinder 11, when the storage tank 21 moves downwards and contacts the arc-shaped rod 13, it will also displace horizontally along the inclination direction of the arc-shaped rod 13. The storage tank 21 drives the bidirectional telescopic rod 27 to rotate via the connecting rod 26, thereby causing the other storage tank 21 to also rotate. When rotation occurs, the downward-moving storage tank 21 also drives the bidirectional telescopic rod 27 to rotate around the shaft I117, thereby driving the other storage tank 21 to move upward simultaneously. The discharge port 23 at the lower end of the storage tank 21 moves to the lower end of the rotating drum 111 and is exposed, thus completing the discharge. When the downward-moving storage tank 21 disengages from the arc-shaped rod 13, due to the horizontal displacement of the storage tank 21, the downward-moving storage tank 21 also disengages from the transmission rod I31. The other upward-moving storage tank 21 moves to the lower end of the limiting device 4, and at the same time, the sliding rod 16 is embedded in the sliding groove 22. Under the elastic force of the elastic telescopic rod 35, the transmission... The moving rod I 31, connecting rod 32 and transmission rod II 33 move upward. The transmission rod II 33 drives the partition plate 34 to move upward. After the partition plate 34 is separated from the vertical plate part of the side baffle 41, since the middle and upper part of the side baffle 41 is an outward inclined plate, the gap between the partition plate 34 and the inclined plate of the middle and upper part of the side baffle 41 gradually increases after the partition plate 34 moves upward. Moreover, the partition plate 34 is an arc-shaped plate with a raised Xiangshan. Under the action of gravity, the tailings slide down to both ends along the arc surface of the upper end of the partition plate 34 and slide down into the storage tank 41 through the gap between the partition plate 34 and the side baffle 41. In this way, there is no need to control the start and stop of the conveyor belt to control the output of the tailings.

[0041] Since the forces on both sides of the rotating rod 114 are different when the distance between the rotating rod 114 and the two magnets 25 is the same, when the magnetic force between the magnet 25 on the side of the storage tank 21 at the higher position and the rotating rod 114 is greater, it pushes the lower end of the rotating rod 114 to move away from the storage tank 21 at the higher position. The lower end of the rotating rod 114 strikes the magnet 25 at the lower position, generating vibration. After the lower end of the rotating rod 114 contacts the magnet 25 connected to the storage tank 21 at the lower position, the repulsive force between the two is greater than the repulsive force on the other side of the rotating rod 114, causing it to move in the opposite direction. After moving a certain distance, the repulsive force of the magnet 25 at the higher position strikes the magnet 25 at the lower position again, generating vibration, and so on. The process continues until a state of equilibrium is reached. When the magnetic force between the magnet 25 on the side of the lower storage tank 21 and the rotating rod 114 is greater, the lower end of the rotating rod 114 is pushed to move closer to the storage tank 21 at the higher position. The lower end of the rotating rod 114 strikes the inner wall of the rotating cylinder 111. At the same time as the lower end of the rotating rod 114 contacts the inner wall of the rotating cylinder 111, the rotating rod 114 also contacts the magnet 25 connected to the higher storage tank 21. After the rotating rod 114 contacts the lower magnet 25, the repulsive force between the two is greater than the repulsive force on the other side of the rotating rod 114, so it will move in the opposite direction. After moving a certain distance, it will strike the lower magnet 25 again due to the repulsive force of the lower magnet 25, generating vibration. This process is repeated until a state of equilibrium is reached.

[0042] After vibration is generated, the vibration can be transmitted to the two storage tanks 21, so that the small particles of tailings inside the storage tank 21 located at the higher position can fully fill the gaps between the large particles of tailings, thus preventing the tailings inside the storage tank 21 at the higher position from being too high and causing the tailings to slide off from both sides. At the same time, the vibration can also shake off the small particles of tailings adsorbed on the inner wall of the storage tank 21 located at the lower position.
