Description

Technical Field

[0001] The invention relates to the technical field of iron tailings mud treatment, in particular to a mine tailings harmless treatment device. Background Art

[0002] The hazards of random discharge of iron tailings slurry include several important characteristics: irreversible damage to the land; metal elements will penetrate into the groundwater and pollute the groundwater source; the evaporated metal vapor will pollute the atmospheric environment; most importantly, the pollution is hidden and is an invisible killer to human health. Tailings slurry needs to be treated. The following three methods are currently used for the treatment of tailings slurry:

[0003] 1) The tailings pond is discharged for natural sedimentation and landfill, the waiting period for treatment is too long, and the sludge cannot be disposed of, which does not meet environmental protection requirements;

[0004] 2) Drying treatment: the tailings slurry is discharged into the drying system, the wastewater is evaporated, and the sludge is quickly dried. The discharged sludge is still used to backfill the mine, but the sludge is not reused;

[0005] 3) Drying treatment method: the sludge is treated by physical pressing. First, the sludge and sewage are separated. The sludge enters the magnetic separator to select the minerals in the sludge, then enters the vibrating screen to screen out the sand, and finally goes to the filter press to dry it. The sewage becomes clear water and the sludge becomes mud cake.

[0006] The above-mentioned pressing and drying method treats the iron tailings mud, reuses the resources, and realizes the harmless treatment of the iron tailings mud. The existing iron tailings mud water separation often adopts the centrifugal separation method to dehydrate the sludge. The processing time is long and the material needs to be loaded and unloaded in batches. It is impossible to achieve continuous mud and water separation, which seriously affects the mud and water separation efficiency. Based on this, a mine tailings harmless treatment device is specially proposed. Through the integrated treatment of automatic loading, extrusion and unloading, continuous sludge dehydration treatment is achieved, and the processing efficiency is higher. Summary of the Invention

[0027] (3) Beneficial effects

[0028] The present invention provides a device for harmless treatment of mine tailings, which has the following beneficial effects:

[0029] (1) The present invention utilizes a driving motor to drive a rotating shaft to rotate a rotating driving plate, thereby squeezing four driving blocks to move, realizing synchronous reciprocating movement of the left and right driving blocks, and realizing synchronous reciprocating movement of the upper and lower driving blocks, so that the grabbing component grabs the iron ore tailings after water filtration on the water filter plate and sends them to the angle plate, and the squeezing component squeezes the iron ore tailings on the angle plate and transports them to the arc plate, and the unloading component is used to remove the iron ore tailings on the arc plate. Without programming, the continuous dehydration processing of the iron ore tailings can be realized, and the dehydration efficiency is higher.

[0030] (2) The present invention utilizes the coordinated arrangement of the first guide bar, the first inclined guide plate and the first guide roller. In the process of the grabbing push rod pushing the vertical plate to move, the position of the first guide roller is adjusted by the first inclined guide plate, so that the mounting plate drives the grabbing plate to move at different heights, thereby realizing the grabbing and conveying action of the iron ore tailings, that is, when the iron ore tailings are below the first guide bar, the iron ore tailings are scraped and sent to the angle plate.

In the process of the material-digging part being lifted upward, the grab plate transports the iron ore tailings to the angle plate.

[0032] (4) The present invention utilizes triangular strips to squeeze out water channels on the iron ore tailings squeezed on the angled plates, thereby facilitating the delivery of squeezed water to the drain mesh for seepage. Furthermore, with the setting of the arc-shaped baffle, the iron ore tailings are effectively prevented from entering the upper portion of the rotating plate, thereby ensuring the normal use of the rotating plate.

[0033] (5) The present invention utilizes the unloading push plate to push the collaborative plate to swing left and right, and under the setting of the support plate, the collaborative plate drives the unloading plate to move a larger distance. In conjunction with the setting of the horizontal groove and the pin shaft, the unloading plate can move back and forth stably, so that the scraper can effectively scrape off the dehydrated iron ore tailings on the arc plate. In conjunction with the setting of the second frame, the second guide bar, the second inclined guide plate and the second guide roller, the leftward and rightward moving processes of the unloading plate are not at the same height, which facilitates the scraper to fall on the arc plate and ensures the effective scraping operation of the scraper.

[0047] Further explanation, as attached Figure 1 As shown, the feed bin 2 and the power cover 3 are fixedly connected to the top of the processing box 1 from left to right, wherein the feed bin 2 is used for temporarily storing materials.

[0048] As a preferred solution, in order to achieve effective filtration of iron tailings mud, a water filter plate 4 is fixedly installed on the left side of the inner cavity of the treatment box 1, and an angle plate 5 is fixedly installed on the right side of the water filter plate 4. The bottom of the inclined end of the angle plate 5 is fixedly connected to a drainage mesh plate 6, and the bottom end of the drainage mesh plate 6 is fixedly connected to an arc plate 7, and an isolation plate 8 is fixedly connected between the arc plate 7 and the bottom of the inner cavity of the treatment box 1. At least four supporting legs 57 are fixedly installed on the bottom of the treatment box 1, and a discharge hopper 58 is connected to the bottom of the treatment box 1 and located on the right side of the isolation plate 8.

[0049] As a preferred solution, after the iron tailings mud on the water filter plate 4 has filtered most of the water, in order to transport the iron tailings mud to the angle plate 5, as shown in the attached Figure 2 As shown, the material grabbing assembly 15 includes a material grabbing push rod 19, the left end of the material grabbing push rod 19 passes through the power cover 3 and is slidably connected to a vertical plate 20, the bottom of the vertical plate 20 is fixedly connected to a mounting plate 21, and the bottom of the mounting plate 21 is fixedly connected to a number of grabbing plates 22 at even intervals, the left side of the power cover 3 is fixedly connected to a first sleeve frame 23, the top and bottom of the inner cavity of the first sleeve frame 23 are fixedly connected to a first guide bar 24 through a connecting rod, the right side of the first guide bar 24 is rotatably connected to a first inclined guide plate 25, and one side of the mounting plate 21 is rotatably connected to a first guide roller 26 used in conjunction with the first guide bar 24 and the first inclined guide plate 25.

[0050] As a preferred solution, in order to cooperate with the iron tailings mud conveyed by the grabbing assembly 15, further conveying and pressing dehydration are carried out, as shown in the attached Figure 2 As shown, the extrusion assembly 16 includes an extrusion push rod 27 and a rotating plate 28. Figure 7As shown, the rotating plate 28 includes a material-prying portion 29 and an extruding portion 30, and the extruding portion 30 is inclined.

The front and rear sides of the rotating plate 28 are rotatably installed inside the processing box 1 through a rotating shaft and are located above the angle plate 5.

[0051] In order to ensure that the water pressed out from the iron tailings mud effectively flows to the drain mesh plate 6, a plurality of triangular plate strips 34 are fixedly connected at even intervals to the lower surface of the rotating plate 28, so that a water flow channel is left on the pressed iron tailings mud.

[0052] To further explain, in order to prevent the accumulation of iron tailings mud on the rotating plate 28 , arc-shaped baffles 33 are fixedly connected to both sides of the upper surface of the rotating plate 28 .

[0053] When the extrusion portion 30 on the rotating plate 28 tilts downward, the iron tailings mud on the angle plate 5 is squeezed. At this time, the distance between the material-diverting portion 29 and the angle plate 5 is large, and the grab plate 22 transports the iron tailings mud to the angle plate 5. When the extrusion portion 30 on the rotating plate 28 tilts upward, the extrusion of the iron tailings mud is released. At this time, the material-diverting portion 29 pushes the iron tailings mud on the angle plate 5 to move, and the grab plate 22 begins to move to the upper left due to the cooperation of the first guide roller 26 and the first inclined guide plate 25.

[0054] As a preferred solution, in order to achieve smooth discharge of dehydrated iron tailings mud, as shown in the attached Figure 2 As shown, the blanking assembly 17 includes a blanking push plate 35 and a support plate 36. The support plate 36 is fixedly mounted on the right side of the power cover 3. The right side of the support plate 36 is rotatably connected to the cooperation plate 37 through a rotating block. The right end of the blanking push plate 35 passes through the power cover 3 and is rotatably connected to the second slider 38. A first slide groove 39 adapted to the second slider 38 is provided at the top left side of the cooperation plate 37. A second slide groove 40 is provided at the bottom left side of the cooperation plate 37, and a third slider 41 is slidably installed inside the second slide groove 40. One side of the third slider 41 is rotatably connected to the blanking plate 43 through a pin shaft 42. A horizontal groove 44 adapted to the pin shaft 42 is provided in the inner cavity of the processing box 1. Figure 8 As shown, the end of the blanking plate 43 away from the collaborative plate 37 is fixedly connected to a sleeve 45, a scraper 46 is slidably installed inside the sleeve 45, and a spring 47 is fixedly connected between the top of the scraper 46 and the top of the inner cavity of the sleeve 45. A second sleeve frame 48 is fixedly connected to the inner cavity of the processing box 1, as shown in the attached Figure 6As shown, the top and bottom of the inner cavity of the second frame 48 are fixedly connected to the second guide bar 49 through a connecting rod, the right side of the second guide bar 49 is rotatably connected to the second inclined guide plate 50, and one side of the blanking plate 43 is rotatably connected to the second guide roller 51 used in conjunction with the second guide bar 49 and the second inclined guide plate 50.

[0055] As a preferred solution, in order to reduce the impurity content in the separated water, the second chute 40 is internally slidably connected to a fourth slider 52, and the fourth slider 52 is arranged below the third slider 41. One side of the fourth slider 52 is rotatably connected to a reciprocating plate 53 through a rotating block. The left side of the reciprocating plate 53 passes through the isolation plate 8 and is fixedly connected to a filter plate 54. The mesh diameter of the filter plate 54 is smaller than the mesh diameter of the water filter plate 4. The bottom of the inner cavity of the treatment box 1 is fixedly connected to a pad 55 used in conjunction with the filter plate 54, and the top of the filter plate 54 is fixedly connected to an inclined guide plate 56. The front of the treatment box 1 is connected to a water outlet pipe 59 between the pad 55 and the isolation plate 8.

[0056] When loading, the iron tailings mud is directly transported to the feed bin 2. After the iron tailings mud falls on the water filter plate 4, most of the water directly enters the bottom of the water filter plate 4. As the iron tailings mud continues to be input, the iron tailings mud moves to the right on the water filter plate 4, and the drive motor 9 is started;

[0057] Grabbing material: The driving motor 9 drives the rotating shaft 10 to rotate the rotating driving plate 11. The rotating driving plate 11 squeezes the driving block 12 set on the left and moves to the left, so that the grabbing push rod 19 pushes the vertical plate 20 to move to the left. During the movement of the vertical plate 20 to the left, it passes through the first inclined guide plate 25 and starts to move to the upper left until it moves to the first guide bar 24. After exceeding the support range of the first guide bar 24, it starts to fall. When the first guide roller 26 falls to the bottom of the first set frame 23, the grabbing plate 22 falls on the water filter plate 4 On, and inserted into the iron tailings mud, as the rotating drive plate 11 continues to rotate, the driving block 12 moves to the right, driving the first guide roller 26 to move to the right, at this time the grab plate 22 transports the iron tailings mud on the water filter plate 4 to the right, as the first guide roller 26 moves to the right, squeezing the first inclined guide plate 25 to move upward, when the first guide roller 26 is no longer in contact with the first inclined guide plate 25, the first inclined guide plate 25 falls and contacts the bottom of the inner cavity of the first sleeve frame 23, transporting the iron tailings mud to the angle plate 5;

[0058] Extrusion: During the process of the material-digging and rotating driving plate 11 driving the driving block 12 arranged on the left side to move to the left, the driving block 12 arranged on the lower side moves upward. At this time, the material-digging part 29 tilts downward, and the iron tailings mud on the angle plate 5 is diverted to the right; during the process of the material-digging and rotating driving plate 11 driving the driving block 12 arranged on the left side to move to the right, the driving block 12 arranged on the lower side moves downward. At this time, the material-digging part 29 is lifted upward to provide a feeding space for the above-mentioned material grabbing step, and the extrusion part 30 squeezes the iron tailings mud on the angle plate 5 downward, and the triangular plate strips 34 squeeze out a water flow channel. The squeezed water flows onto the drain mesh plate 6 and falls below the drain mesh plate 6;

[0059] Unloading: During the process of rotating the driving plate 11 and driving the driving block 12 set on the lower side to move downward, the driving block 12 set on the right side moves to the left, and the unloading push plate 35 pulls the cooperative plate 37 to make its bottom swing to the right. During the process, it drives the third slider 41 to make the pin 42 move to the right in the horizontal groove 44, driving the unloading plate 43 to move to the right, so that the sleeve 45 drives the scraper 46 to scrape the iron tailings mud on the curved plate 7 into the discharge hopper 58 for discharge. During the movement of the unloading plate 43, the second guide roller 51 lifts the second inclined guide plate 50. After the second guide roller 51 disengages from the second inclined guide plate 50, the second inclined guide plate 50 falls to the position aligned with the second sleeve frame. 48 contacts the bottom of the inner cavity, and the rotating driving plate 11 rotates to drive the driving block 12 set on the lower side to move upward. In the process, the driving block 12 set on the right side moves to the right, and the blanking push plate 35 pulls the cooperative plate 37 to make its bottom swing to the left. In the process, it drives the third slider 41 to make the pin 42 move to the left in the horizontal groove 44, and drives the blanking plate 43 to move to the left. In the process, the second guide roller 51 moves to the upper left along the second inclined guide plate 50, so that the scraper 46 moves to above the curved plate 7, until the second guide roller 51 exceeds the support range of the second guide bar 49 and falls to the bottom of the inner cavity of the second set frame 48. At this time, the scraper 46 falls into the curved plate 7;

[0060] The impurities in the water are further filtered: the water filtered out of the filter plate 4 falls on the pad 55 and the inclined guide plate 56, is filtered by the filter plate 54, and is discharged from the outlet pipe 59. During the left and right swing of the cooperative plate 37, the reciprocating plate 53 is driven to move back and forth, pushing and accumulating the impurities filtered out of the pad 55. Figure 1 As shown, a sealing door is provided on the front of the processing box 1, and an observation window is provided on the sealing door. When a large amount of accumulated impurities is observed, the loading is stopped and the sealing door is opened for cleaning.
