Description

Technical Field

[0001] The utility model relates to the field of environmental protection treatment equipment for vanadium-titanium magnetite tailings, in particular to equipment for recovering vanadium-titanium slag from vanadium-titanium magnetite tailings. Background Art

[0002] Vanadium-titanium magnetite is an important mineral resource, and its tailings often contain a considerable amount of vanadium-titanium slag. These vanadium-titanium slags have extremely high economic value and can be used to manufacture various high-performance materials. However, in the traditional tailings treatment process, these valuable vanadium-titanium slags are often ignored or not fully recovered. Therefore, in order to improve the comprehensive utilization rate of resources and reduce waste, it is crucial to develop specialized vanadium-titanium slag recovery equipment.

[0003] Secondly, the improvement of environmental protection awareness has also promoted the research and development and application of vanadium-titanium slag recovery equipment. The accumulation of tailings not only occupies a large amount of land resources, but also may pollute the surrounding environment. By effectively recycling vanadium-titanium slag, the discharge of tailings can be reduced, the potential threat to the environment can be reduced, and the green utilization of resources can be achieved.

[0004] The vanadium-titanium slag recovery equipment from vanadium-titanium magnetite tailings is a complex and professional system, which is mainly used to effectively recover vanadium-titanium slag from tailings to improve resource utilization and economic benefits.

[0005] In the prior art, vanadium-titanium slag is usually recycled by means of magnet screening or the like. However, the recycling rate of vanadium-titanium slag in the prior art is low, and it cannot form efficient utilization. It is easy to contain more impurities, thereby reducing the comprehensive utilization rate. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art that the comprehensive utilization rate is less increased due to the low recycling efficiency, and provide a vanadium-titanium magnetite tailings vanadium-titanium slag recovery equipment. By sliding the magnetic suction screening tower, the amount of the waste part of the vanadium-titanium slag entering the flotation part can be effectively reduced, thereby achieving preliminary screening of the effective part of the waste slag, improving the recovery efficiency of the vanadium-titanium slag, and increasing the comprehensive utilization rate of the vanadium-titanium slag.

[0007] The purpose of the utility model is mainly achieved through the following technical solutions:

[0008] The vanadium-titanium magnetite tailings vanadium-titanium slag recovery equipment comprises a crushing bucket bin, a crushing drive cover is provided above the crushing bucket bin, and the crushing drive cover can be inserted into the crushing bucket bin;

[0009] A magnetic screening tower is fixed below the crushing bucket bin, a waste slag collecting part is provided below the magnetic screening tower, a flotation part is provided on the side of the waste slag collecting part, a transfer track is fixed above the waste slag collecting part and the flotation part, the transfer track spans the waste slag collecting part and the flotation part, and the magnetic screening tower is slidably connected to the transfer track.

[0010] At present, when treating vanadium-titanium magnetite tailings, it is usually necessary to go through processes such as crushing, screening, flotation, and drying to complete the recycling of vanadium-titanium slag. The tailings after screening will directly enter the flotation operation, thereby replacing a large amount of waste slag. A large amount of waste slag needs to be removed during the flotation process. In the process of removal, some useful materials will be lost, resulting in a reduction in the comprehensive utilization rate of vanadium-titanium slag.

[0011] The embodiment of the present application sets a transfer track. After the tailings are crushed in the crushing hopper, the tailings are screened by a magnetic screening tower. The waste slag in the screening process is collected by a waste slag collecting part. The tailings after screening can be transferred by the transfer track and slide directly to the top of the flotation part. At this time, the screened tailings are put into the flotation part for flotation operation. The sliding transfer of the transfer track can effectively speed up the efficiency of putting the tailings into the flotation part after screening, and can improve the utilization rate of the vanadium-titanium slag in the flotation part by screening out the waste slag, thereby achieving the purpose of enhancing the comprehensive utilization rate of the vanadium-titanium slag.

[0012] Furthermore, the crushing drive cover includes a grinding motor, the output shaft of the grinding motor is connected to a rotating shaft, and the rotating shaft is inserted into the crushing bucket bin;

[0013] The crushing bucket bin comprises a bin body, in which a grinding wall and a grinding column are arranged, the grinding wall is fixed to the bin body, the grinding column is rotatably connected to the bin body, and the rotating shaft can be inserted into the grinding column and drive the grinding column to rotate.

[0014] In the embodiment of the present application, the crushing drive cover drives the rotating shaft to rotate through the grinding motor, and the rotating shaft is used to drive the grinding column to rotate. The grinding column is used to squeeze with the grinding wall to grind and crush the tailings. By controlling the gap between the grinding column and the grinding wall, the grinding fineness can be effectively controlled. The tailings introduced into the crushing bucket will form an accumulation between the grinding column and the grinding wall, and the tailings fragments above will squeeze the tailings fragments below, thereby accelerating the grinding efficiency. By utilizing the tailings' own weight and the squeezing between the grinding column and the grinding wall, the purpose of crushing the tailings can be effectively achieved, which is beneficial to the recovery of the useful part of the vanadium-titanium slag.

[0015] Furthermore, the grinding column includes a grinding body, the end surface of the grinding body is provided with a limiting hole, the end of the rotating shaft is provided with a detachable limiting buckle, and the detachable limiting buckle can be inserted into the limiting hole and lock the relative rotation of the rotating shaft and the grinding body.

[0016] In the embodiment of the present application, the grinding body is used to squeeze with the grinding wall to form a grinding effect, and the limiting hole and the detachable limiting buckle are plugged into and engaged with each other, so as to achieve the purpose of limiting the relative rotation of the rotating shaft and the grinding body. In this way, when the rotating shaft is driven to rotate, the grinding body can be driven to rotate to complete the grinding effect, and the grinding can also be paused by removing the detachable limiting buckle.

[0017] Furthermore, a socket is provided on the warehouse body, and the size of the socket is sufficient to accommodate the passage of the rotating shaft. A rotating bracket is provided below the grinding column. The rotating bracket is rotatably connected to the grinding column through a bearing, and the rotating bracket is fixed to the warehouse body.

[0018] In the embodiment of the present application, the socket on the bin body can effectively accommodate the insertion of the rotating shaft, so that the rotating shaft can be taken out for maintenance and inserted to drive the grinding column. The weight of the grinding column is supported by the rotating bracket, and the bearing enables the grinding column to effectively complete the rotation and rotate relative to the grinding wall to achieve grinding.

[0019] Furthermore, the magnetic attraction screening tower comprises a tower body, wherein a plurality of magnetic attraction screening inclined plates are arranged in the tower body, one end of the magnetic attraction screening inclined plates is connected to the tower body, and the other end thereof extends in the axial direction of the tower body, and the magnetic attraction screening inclined plates are gradually inclined upward from the tower body to the axis of the tower body;

[0020] A fan is provided on the tower body, and the air outlet of the fan is aligned with the upper surface of the magnetic attraction screening inclined plate;

[0021] An exhaust port is arranged on the top of the tower body.

[0022] In the prior art, the crushed tailings are often screened by combining magnetic attraction with gravity. However, since the magnetic attraction at each position is uncontrollable and there are too many factors affecting the screening method, a large amount of usable part will be lost, resulting in a decrease in the comprehensive utilization rate of vanadium-titanium slag.

[0023] In the embodiment of the present application, the magnetic attraction screening inclined plate is tilted upward, and the vanadium-titanium slag that is not adsorbed by the magnetic attraction screening inclined plate is screened out by means of a fan, and its own weight is used to allow the waste to enter the waste slag collection part. An exhaust port is provided at the top of the tower body to maintain the pressure balance inside the tower body, and the force of the fan can effectively control the magnitude of the force acting on the vanadium-titanium slag, thereby preventing the vanadium-titanium slag with smaller magnetic adsorption force from falling into the range of the waste slag, thereby achieving the purpose of reducing the loss of the recoverable part of the vanadium-titanium slag, thereby improving the comprehensive utilization rate of the vanadium-titanium slag.

[0024] Furthermore, a sliding bracket is fixed on the tower body, and the magnetic attraction screening inclined plate is slidably connected to the sliding bracket.

[0025] In the embodiment of the present application, in order to facilitate the pouring of the screened vanadium-titanium slag into the flotation tank and speed up the production efficiency, a sliding bracket is provided to facilitate the use of its own weight to pour the vanadium-titanium slag into the flotation tank. The sliding of the magnetic screening inclined plate can be driven by an electric telescopic rod, and the magnetic force of the magnetic screening inclined plate can be achieved by powering on and off.

[0026] Furthermore, the magnetic attraction screening inclined plate includes a plate body, on which a plurality of electromagnetic groups are arranged, and the electromagnetic groups are evenly distributed on the plate body.

[0027] In the embodiment of the present application, the distribution of the electromagnetic group on the plate is utilized to divide the magnetic attraction into several small areas, thereby avoiding the reduction of the adsorption force caused by the uneven distribution of the magnetic force on the plate, which makes it inconvenient to adjust the blowing power of the fan and causes the loss of the recoverable part of the vanadium-titanium slag.

[0028] Furthermore, the electromagnetic group includes three electromagnetic suction balls, and the line connecting the centers of the three electromagnetic suction balls forms an equilateral triangle.

[0029] In the present application, an electromagnetic suction ball formed by connecting the ball centers to form an equilateral triangle is used as a source of magnetic force for adsorbing vanadium-titanium slag, which can ensure that the magnetic force distribution within each electromagnetic group is relatively even, thereby achieving a more uniform magnetic coverage on the plate.

[0030] Furthermore, it comprises a second screening assembly and a third screening assembly, and the magnetic screening inclined plate, the second screening assembly and the third screening assembly are symmetrically and alternately distributed in the longitudinal direction of the tower body with the axis of the tower body as a reference.

[0031] In the embodiment of the present application, the second screening component and the third screening component both include parts with magnetic attraction. Through the second screening component and the third screening component, more levels of screening are performed above or below the magnetic screening inclined plate. On the basis of ensuring that the screened vanadium-titanium slag has a higher purity, the recyclable part of the vanadium-titanium slag can be retained as much as possible, thereby improving the comprehensive utilization rate.

[0032] Furthermore, the transfer track includes a track body, in which a plurality of bearing wheels are embedded. The bearing wheels can slide back and forth along the track body, and the magnetic screening tower is fixed to the bearing wheels.

[0033] In the embodiment of the present application, the magnetic screening tower bears the weight through the load-bearing wheel and limits the direction of movement through the restriction of the track body. During the sliding process of the load-bearing wheel, the magnetic screening tower can be effectively carried to reciprocate between the flotation part and the waste residue collection part.

[0034] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0035] (1) The utility model can effectively speed up the efficiency of feeding tailings into the flotation section after screening by sliding transfer of the transfer track, and can improve the utilization rate of vanadium-titanium slag in the flotation section by screening out waste slag, thereby achieving the purpose of enhancing the comprehensive utilization rate of vanadium-titanium slag.

[0036] (2) The utility model tilts the magnetic screening inclined plate upward, and screens out the vanadium-titanium slag that is not adsorbed by the magnetic screening inclined plate by means of a fan, and uses its own weight to allow the waste to enter the waste slag collection section. The force of the fan can effectively control the magnitude of the force acting on the vanadium-titanium slag, thereby preventing the vanadium-titanium slag with a smaller magnetic adsorption force from falling into the range of the waste slag, thereby achieving the purpose of reducing the loss of the recoverable part of the vanadium-titanium slag, thereby improving the comprehensive utilization rate of the vanadium-titanium slag.

[0037] (3) The utility model utilizes the distribution of the electromagnetic group on the plate body to divide the magnetic attraction into several small areas, thereby avoiding the reduction of the adsorption force caused by the uneven distribution of the magnetic force on the plate body, which makes it inconvenient to adjust the blowing power of the fan and causes the loss of the recoverable part of the vanadium-titanium slag.

[0050] In practical application of this embodiment, the magnetic screening tower 3 is first slid to the top of the waste slag collecting part 5, and the tailings poured into the crushing bucket 2 can be effectively crushed by adding the crushing drive cover 1 to the crushing bucket 2. The tailings are crushed to form vanadium-titanium slag, and the magnetic force of the magnetic screening tower 3 is turned on by power, and the vanadium-titanium slag is screened in the magnetic screening tower 3. The waste slag in the screened vanadium-titanium slag falls into the waste slag collecting part 5 by its own weight, and the magnetic screening tower 3 is moved on the transfer track 4. The magnetic force of the magnetic screening tower 3 is disconnected by power off, and the vanadium-titanium slag is poured into the flotation part 6 for flotation operation. After flotation, a drain pipe 7 is opened at the bottom of the flotation part 6, and the vanadium-titanium slag is floated and screened while the flotation liquid is discharged in stages, and then the recyclable vanadium-titanium slag is obtained through separation and drying and other steps.

[0051] In this embodiment, the magnetic screening tower 3 is moved by using the transfer track 4, so that the magnetic screening tower 3 can effectively screen the waste slag and the recoverable part of the vanadium-titanium slag, thereby improving the recovery rate and the comprehensive utilization rate.

[0052] The crushing drive cover 1 includes a grinding motor 11, the output shaft of the grinding motor 11 is connected to a rotating shaft 12, and the rotating shaft 12 is inserted into the crushing bucket 2;

[0053] The crushing bucket bin 2 includes a bin body 22, and a grinding wall 23 and a grinding column 24 are arranged in the bin body 22. The grinding wall 23 is fixed to the bin body 22, and the grinding column 24 is rotatably connected to the bin body 22. The rotating shaft 12 can be inserted into the grinding column 24 and drive the grinding column 24 to rotate.

[0054] The grinding column 24 includes a grinding body 241, and the end face of the grinding body 241 is provided with a limiting hole 242. The end of the rotating shaft 12 is provided with a detachable limiting buckle 13, and the detachable limiting buckle 13 can be inserted into the limiting hole 242 and lock the relative rotation of the rotating shaft 12 and the grinding body 241.

[0055] The grinding column 24 in this embodiment has a fixed size, so that the gap between the grinding column 24 and the grinding wall 23 remains unchanged, ensuring that the grinding fineness is fixed. When different grinding finenesses are required, the grinding fineness can be adjusted by replacing the grinding column 24.

[0056] The warehouse body 22 is provided with a socket 21 , and the size of the socket 21 is sufficient to accommodate the rotation shaft 12 passing through. A rotating bracket 25 is provided below the grinding column 24 , and the rotating bracket 25 is rotatably connected to the grinding column 24 via a bearing. The rotating bracket 25 is fixed to the warehouse body 22 .

[0057] In this embodiment, the tailings and gravel in the crushing bucket 2 are ground between the grinding column 24 and the grinding wall 23. After the crushing drive cover 1 is covered on the bin body 22, the rotating shaft 12 is inserted into the bin body 22 and the detachable limit buckle 13 is inserted into the limit hole 242. By locking the detachable limit buckle 13 and the limit hole 242, the grinding motor 11 is turned on, and the rotating shaft 12 can drive the grinding body 241 to rotate, thereby forming a relative rotation between the grinding body 241 and the grinding wall 23, and vanadium-titanium slag is obtained during the self-weight extrusion of the tailings fragments and the grinding of the grinding body 241 and the grinding wall 23.

[0058] The magnetic screening tower 3 includes a tower body 31, and a plurality of magnetic screening inclined plates 34 are arranged in the tower body 31. One end of the magnetic screening inclined plates 34 is connected to the tower body 31, and the other end thereof extends in the axial direction of the tower body 31. The magnetic screening inclined plates 34 gradually tilt upward from the tower body 31 to the axis of the tower body 31.

[0059] The tower body 31 is provided with a fan 33, and the air outlet of the fan 33 is aligned with the upper surface of the magnetic screening inclined plate 34;

[0060] An exhaust port 32 is disposed on the top of the tower body 31 .

[0061] A sliding bracket 35 is fixed on the tower body 31 , and the magnetic screening inclined plate 34 is slidably connected to the sliding bracket 35 .

[0062] In this embodiment, the tower body 31 of the magnetic screening tower 3 is used to accommodate the magnetic screening operation. The magnetic screening inclined plate 34 in the tower body 31 can accommodate the accumulation of vanadium-titanium slag. Turning on the fan 33 can effectively blow the vanadium-titanium slag off the magnetic screening inclined plate 34, thereby achieving the purpose of screening. Energizing the magnetic screening inclined plate 34 can effectively adsorb the recyclable part. Adjusting the wind force of the fan 33 allows the magnetic attraction force to counteract the wind force, thereby achieving the purpose of collecting the recyclable part of the vanadium-titanium slag.

[0063] After the waste slag is removed, the position of the magnetic screening tower 3 is transferred through the transfer track 4, the power is disconnected to eliminate the magnetic attraction, and the position of the magnetic screening inclined plate 34 is moved by the sliding bracket 35, thereby achieving the purpose of releasing the vanadium-titanium slag and facilitating the completion of subsequent flotation operations.

[0064] The magnetic attraction screening inclined plate 34 includes a plate body 342 , on which a plurality of electromagnetic groups are disposed, and the electromagnetic groups are evenly distributed on the plate body 342 .

[0065] The electromagnetic group includes three electromagnetic suction balls 341 , and the line connecting the centers of the three electromagnetic suction balls 341 forms an equilateral triangle.

[0066] In this embodiment, the magnetic screening inclined plate 34 is supported by the plate body 342, and the magnetic attraction force is dispersed by using the evenly distributed electromagnetic group to avoid uneven distribution of the magnetic attraction force on the plate surface causing inconvenience in wind force regulation, thereby reducing the recovery rate of vanadium-titanium slag.

[0067] The three electromagnetic suction balls 341 in the same electromagnetic group are distributed as an equilateral triangle through the line connecting the ball centers, so that the magnetic suction force on the plate 342 is more stable and the mutual repulsion of the magnetic suction force can be avoided to a certain extent.

[0068] It also includes a second screening component 36 and a third screening component 37. The magnetic screening inclined plate 34, the second screening component 36 and the third screening component 37 are symmetrically and alternately distributed in the longitudinal direction of the tower body 31 based on the axis of the tower body 31.

[0069] The transfer track 4 includes a track body 41 , in which a plurality of bearing wheels 42 are embedded. The bearing wheels 42 can slide back and forth along the track body 41 , and the magnetic screening tower 3 is fixed to the bearing wheels 42 .

[0070] In this embodiment, the second screening component 36 and the third screening component 37 both include parts with magnetic attraction. Through the second screening component 36 and the third screening component 37, more levels of screening can be performed above or below the magnetic screening inclined plate 34. On the basis of ensuring that the screened vanadium-titanium slag has a higher purity, the recyclable part of the vanadium-titanium slag can be retained as much as possible, thereby improving the comprehensive utilization rate.

[0071] In another implementation of this embodiment, the second screening component 36 and the third screening component 37 can use the same structure as the combination of the magnetic screening inclined plate 34 and the fan 33 to screen the magnetic material, thereby reducing the manufacturing cost of this embodiment.

[0072] The magnetic screening tower 3 carries the weight through the load-bearing wheel 42 and limits the movement direction through the restriction of the track body 41. During the sliding process of the load-bearing wheel 42, the magnetic screening tower 3 can be effectively carried to reciprocate between the flotation part 6 and the waste residue collection part 5.

[0073] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
