Description

Technical Field

[0001] The invention relates to the technical field of ore ball manufacturing equipment, in particular to a vanadium-titanium ore pelletizing device, and also particularly to a method for using the vanadium-titanium ore pelletizing device. Background Art

[0002] With the increasing mining volume, high-quality vanadium-titanium resources are gradually decreasing, and are replaced by low-quality vanadium-titanium resources. Vanadium-titanium magnetite is accompanied by vanadium, titanium, chromium and other components. High-vanadium and high-chromium magnetite has the disadvantages of coarse particle size and poor spheroidization.

[0003] When making balls in the existing ball mill, the vanadium-titanium ore is directly conveyed to the inclined turntable by conveying equipment. The rotation of the inclined turntable will drive the vanadium-titanium ore to rotate synchronously, so that the vanadium-titanium ore will collide and rub against each other when rotating, and the vanadium-titanium ore particles will be formed into balls. Although this technical solution can make balls in batches, the vanadium-titanium ore material will accumulate in large quantities when entering the inclined turntable, resulting in the inclined turntable can only rotate the vanadium-titanium ore synchronously for grinding, making it difficult to ensure the uniformity of grinding. Accumulated grinding will cause excessive grinding of the vanadium-titanium ore, which will increase the loss of ore materials.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] See also Figures 1 to 13 As shown, a vanadium-titanium ore pelletizing device includes a screening and grinding ball device for uniformly grinding the vanadium-titanium ore, the screening and grinding ball device includes a fixed mounting frame 1, a stirring and splicing silo 2 is installed on the fixed mounting frame 1, a spiral grinding column 3 is installed at the bottom of the stirring and splicing silo 2, a disassembly mounting device 4 is installed at both upper and lower ends of the spiral grinding column 3, a plurality of mutually assembled spliced ​​grinding screen plates 5 are installed on the disassembly mounting device 4, the spliced ​​grinding screen plates 5 are sleeved on the outer side of the spiral grinding column 3, a dust reduction guide device 7 is also sleeved on the outer side of the spliced ​​grinding screen plates 5, a separation and filtering device 8 for screening ore is installed at the bottom of the dust reduction guide device 7, and the screening and grinding ball device also includes a reverse rotation device 6 for driving the disassembly mounting device 4 and the spiral grinding column 3 to rotate.

[0039] The vanadium-titanium ore is conveyed to the interior of the stirring and connecting silo 2 by a conveyor. The stirring and connecting silo 2 is used to guide the vanadium-titanium ore to fall into the spiral grinding column 3 and the spliced ​​grinding screen plate 5. The reverse rotation device 6 drives the disassembly and installation device 4 and the spiral grinding column 3 to rotate synchronously in the opposite direction. When the disassembly and installation device 4 rotates, the connecting grinding screen plate will rotate accordingly. When the spliced ​​grinding screen plate 5 and the spiral grinding column 3 rotate, the vanadium-titanium ore in the gap will rotate. The rotating vanadium-titanium ore rotates and rubs against each other, which will grind the vanadium-titanium ore into vanadium-titanium ore balls. When the size of the vanadium-titanium ore balls is worn to a suitable size, the vanadium-titanium ore balls will pass through the spliced ​​grinding screen plate. 5. The spliced ​​grinding screen plate 5 can screen the vanadium-titanium ore balls, effectively avoiding the grinding specifications of the vanadium-titanium ore balls being too large. Qualified vanadium-titanium ore balls and smaller vanadium-titanium ore balls will pass through the spliced ​​grinding screen and enter the dust reduction guide device 7. The dust reduction guide device 7 can effectively guide the vanadium-titanium ore balls to fall into the separation and filtration device 8. The dust reduction guide device 7 can effectively carry out dust reduction treatment on the transported vanadium-titanium ore balls. The separation and filtration device 8 will grade and screen the manufactured vanadium-titanium ore balls. The graded screening will classify and process the smaller vanadium-titanium ore balls, grinding powder and dust reduction water in the vanadium-titanium ore balls to ensure production quality.

[0040] See also Figure 6 and Figure 7 As shown, the stirring and mixing silo 2 includes a storage hopper 21 installed on a fixed mounting frame 1, a first water spray pipe 22 is provided on the top of the storage hopper 21, a conical wheel 23 is installed at the axial position of the storage hopper 21, the bottom of the conical wheel 23 is connected to the spiral grinding column 3, and a plurality of stirring blades 24 are provided on the outer side of the conical wheel 23.

[0041] The storage hopper 21 is used to store vanadium-titanium ore. The storage hopper 21 will gather the vanadium-titanium ore to the axis. The first water spray pipe 22 on the storage hopper 21 will spray water onto the vanadium-titanium ore, effectively avoiding dust diffusion during feeding. The conical wheel 23 is connected to the spiral grinding column 3. The spiral grinding column 3 will drive the conical wheel 23 to rotate synchronously when rotating and grinding. When the conical wheel 23 rotates, it will drive the stirring blades 24 to rotate. The stirring blades will stir the material at the discharge port of the storage hopper 21, effectively ensuring the smoothness of feeding of the storage hopper 21.

[0042] See also Figure 6 and Figure 8 As shown, the outer wall of the spiral grinding column 3 is provided with a first anti-slip surface 31 , and the outer wall of the spiral grinding column 3 is also wound with several circles of inclined spiral blades 32 , and the surface of the inclined spiral blades 32 is provided with a second anti-slip surface 33 .

[0043] The stirring and connecting silo 2 is used to guide the vanadium-titanium ore to fall into the spiral grinding column 3 and the spliced ​​grinding screen plate 5. The reverse rotation device 6 drives the disassembly and installation device 4 and the spiral grinding column 3 to rotate synchronously in the opposite direction. When the spiral grinding column 3 rotates, the inclined spiral blades 32 on the outside will guide the vanadium-titanium ore to rotate spirally along the outer wall of the spiral grinding column 3. The inclined spiral blades 32 of the spiral grinding column 3 will drive the vanadium-titanium ore to rotate spirally along the outer wall of the spiral grinding column 3 when guiding the rotation. The first anti-slip surface 31 of the spiral grinding column 3 and the second anti-slip surface 33 of the inclined spiral blades 32 are used to increase friction. The vanadium-titanium ore will roll and grind when it contacts the rotating first anti-slip surface 31 and the second anti-slip surface 33. The surface of the inclined spiral blades 32 is in an inclined state, so that the polished vanadium-titanium ore will conflict with the inner wall of the spliced ​​grinding screen plate 5. If the vanadium-titanium ore is polished to a suitable size, it will directly pass through and fall into the area to be processed.

[0044] See also Figure 3 and Fig. 9 As shown, the disassembly mounting device 4 includes a rotating mounting device 41 which is sleeved on the outer wall of the spiral grinding column 3. The rotating mounting device 41 is provided with a blanking hole 42. A plurality of fixed slots 43 are also installed on the rotating mounting device 41. A lifting clamp sleeve 44 is also installed on the outer side of the rotating mounting device 41. A threaded adjustment rod 45 is installed between the lifting clamp sleeve 44 and the rotating mounting device 41.

[0045] The rotating mounting device 41 is rotatably connected to the spiral grinding column 3, the blanking hole 42 on the rotating mounting device 41 is used to connect the discharge port of the stirring and splicing silo 2, the fixed card slot 43 on the rotating mounting device 41 is used to clamp and fix the spliced ​​and polished sieve plate 5, and the lifting card sleeve 44 is used to limit and block the fixed card slot 43. When the spliced ​​and polished sieve plate 5 needs to be installed, the staff rotates the threaded adjusting rod 45, and the threaded adjusting rod 45 will drive the lifting card sleeve 44 to move upward. When the lifting card sleeve 44 moves upward, it will open the opening of the fixed card slot 43, and the staff will then clamp the spliced ​​and polished sieve plate 5 into the fixed card slot 43. After the spliced ​​and polished sieve plate 5 is clamped into the fixed card slot 43, the staff will drive the lifting card sleeve 44 to descend through the threaded adjusting rod 45 to seal the opening of the fixed card slot 43, so that the spliced ​​and polished sieve plate 5 is clamped and fixed, which is convenient for disassembly and replacement of the spliced ​​and polished sieve plate 5.

[0046] See also Figure 3 and Fig.10 As shown, the spliced ​​and polished sieve plate 5 is semicircular, and a plurality of limit clamping columns 51 are provided at the upper and lower ends of the spliced ​​and polished sieve plate 5. The inner wall of the spliced ​​and polished sieve plate 5 is covered with discharge sieve holes 52. The inner wall of the spliced ​​and polished sieve plate 5 is also provided with a third anti-slip surface 53. An assembling groove 54 is provided on one side of the spliced ​​and polished sieve plate 5, and an assembling protrusion 55 is provided at the end of the spliced ​​and polished sieve plate 5 away from the assembling groove 54.

[0047] The spliced ​​and polished sieve plate 5 is semicircular, and the limit clamping column 51 of the spliced ​​and polished sieve plate 5 is used to cooperate with the fixed clamping groove 43 for clamping installation. When the staff splices and installs the two spliced ​​and polished sieve plates 5 to disassemble the fixed clamping groove 43 of the installation tool 4, the assembly protrusions 55 and the assembly grooves 54 on the sides of the two spliced ​​and polished sieve plates 5 will be mutually clamped, so that the spliced ​​and polished sieve plate 5 is sleeve-shaped, and the spiral polishing column 3 is set inside. The third anti-slip surface 53 of the spliced ​​and polished sieve plate 5 is in contact with the fixed clamping groove 43 when rotating. When the vanadium-titanium ore comes into contact with the vanadium-titanium ore, it will rub against the vanadium-titanium ore, causing the vanadium-titanium ore to rotate and rub. When the vanadium-titanium ore is rotated and ground into balls, when the size of the titanium ore ball matches the size of the discharge sieve hole 52 of the spliced ​​and polished screen plate 5, the vanadium-titanium ore ball will directly pass through the discharge sieve hole 52 and enter the dust reduction guide device 7. The spliced ​​and polished screen plate 5 can effectively improve the ease of replacement through its assembleable and disassembled structure, and screening through the discharge sieve hole 52 can effectively improve the quality of the titanium ore balls.

[0048] See also Figure 3 and Figure 4 As shown, the reverse rotation device 6 includes a rotating mounting sleeve 61 installed at the bottom of the disassembly mounting device 4, a gear ring 62 is installed inside the rotating mounting sleeve 61, a driven gear 65 is provided at the axial position of the gear ring 62, the driven gear 65 is connected to the bottom of the spiral grinding column 3, a driving gear 64 is provided between the driven gear 65 and the gear ring 62, and the reverse rotation device 6 also includes a first rotation driver 63 that drives the driving wheel to rotate.

[0049] The first rotary driver 63 is preferably a servo motor. When it is necessary to drive the disassembly and installation device 4 and the spiral grinding column 3 to rotate synchronously in the opposite direction, the servo motor will drive the driving gear 64 to rotate. When the driving gear 64 rotates, it will synchronously drive the driven gear 65 and the ring gear 62 to rotate. When the driven gear 65 and the ring gear 62 rotate, the rotation direction is directional drive. The driven gear 65 will drive the spiral grinding column 3 to rotate clockwise, and the ring gear 62 will drive the rotating installation sleeve 61 to rotate. The rotating installation sleeve 61 also drives the driving and disassembly and installation device 4 to rotate counterclockwise. When the driving and disassembly and installation device 4 rotates, the spliced ​​grinding screen plate 5 will rotate accordingly. The synchronous reverse rotation of the spliced ​​grinding screen plate 5 and the spiral grinding column 3 can effectively improve the grinding effect of the vanadium-titanium ore.

[0050] See also Figures 1 to 6 As shown, the dust reduction guiding device 7 includes a bidirectional ball screw slide 71 installed at the bottom of the fixed mounting frame 1, a plurality of movable mounting frames 72 are symmetrically installed on the bidirectional ball screw slide 71, a docking mounting sleeve 73 is installed on each of the movable mounting frames 72, a second water spray pipe 74 is installed on the top of the docking mounting sleeve 73, a plurality of connecting buckles are installed on the side of the docking mounting sleeve 73, and a guide hopper 75 is provided at the bottom of the bidirectional ball screw slide 71.

[0051] The bidirectional ball screw slide 71 can drive multiple mobile mounting frames 72 to adjust and move to both sides. When the multiple mobile mounting frames 72 expand and move, they will drive the docking mounting sleeve 73 to move synchronously. The connecting buckle of the docking mounting sleeve 73 is convenient for the staff to fix it by bolts. When the docking mounting sleeves 73 are close to each other, they will be sleeved on the outside of the spliced ​​and polished screen plate 5, effectively guiding the titanium ore balls passing through the spliced ​​and polished screen plate 5 to fall into the guide hopper 75, and the guide hopper 75 will gather the titanium ore balls and transport them to the separation and filtration device 8. When the docking mounting sleeve 73 guides the titanium ore balls to fall, the second water pipe 74 will spray water from top to bottom to effectively reduce dust. At the same time, the docking mounting sleeve 73 can be separated and adjusted, which is convenient for the staff to perform daily maintenance inside the equipment.

[0052] See also Figure 6 and Fig.11 As shown, the separation and filtering device 8 includes a guide rail 82 installed at the bottom of the dust reduction guide device 7, a shaking screening plate 81 is installed at the upper end of the guide rail 82, a filter layer plate 83 is obliquely installed below the shaking screening plate 81, a fixed base 84 is installed below the guide rail 82, a plurality of buffer springs 85 are installed between the fixed base 84 and the guide rail 82, and a sewage tank 86 is also installed below the guide rail 82.

[0053] The dust reduction guiding device 7 guides and transports the manufactured vanadium-titanium ore balls to the shaking screening plate 81, and the shaking screening plate 81 filters and screens the vanadium-titanium ore balls, so that the smaller vanadium-titanium ore balls, grinding powder and dust reduction water in the vanadium-titanium ore balls fall onto the filter layer plate 83. The shaking screening plate 81 transports qualified vanadium-titanium ore balls to the processing area, and the filter layer plate 83 transports unqualified vanadium-titanium ore balls and grinding powder to the waste area. At the same time, the dust reduction water will penetrate into the filter layer plate 83 and fall into the sewage pool 86. The buffer spring 85 between the fixed base 84 and the guide rail 82 can effectively reduce the vibration force of the equipment.

[0054] See also Figures 11 to 13 As shown, the shaking screening plate 81 includes a rotating screen plate 811 installed on the guide rail 82, and a plurality of slip-limiting grooves 8111 are provided on the rotating screen plate 811, and a plurality of sorting screen holes 8112 are provided inside the slip-limiting grooves 8111. A limiting sleeve 8113 is provided at the bottom of the shaking screening plate 81. The shaking screening plate 81 also includes a rotating mounting shaft 813 installed on the guide rail 82, and the rotating mounting shaft 813 is arranged inside the limiting sleeve 8113. A rotating protrusion 814 is also installed on the rotating mounting shaft 813. The shaking screening plate 81 also includes a second rotating driver 812 for driving the rotating mounting shaft 813 to rotate.

[0055] The second rotary driver 812 is preferably a servo motor, and the dust reduction guiding device 7 guides and transports the manufactured vanadium-titanium ore balls to the rotating screen plate 811, and the servo motor drives the rotating mounting shaft 813 to rotate. When the rotating mounting shaft 813 rotates, it drives the rotating protrusion 814 to rotate inside the limiting sleeve 8113, and when the rotating protrusion 814 rotates inside the limiting sleeve 8113, it makes one end of the rotating screen plate 811 swing up and down, and when the rotating screen plate 811 swings up and down, it makes the vanadium-titanium ore balls vibrate, and the vanadium-titanium ore balls enter the limited slip groove 8111 of the rotating screen plate 811 in turn. The limited slip groove 8111 can effectively slow down the sliding speed, and the sorting sieve hole 8112 inside the limited slip groove 8111 can effectively make the smaller vanadium-titanium ore balls, grinding powder and dust reduction water in the vanadium-titanium ore balls fall onto the filter layer plate 83.

[0056] A method for using a vanadium-titanium ore pelletizing device comprises the following steps:

[0057] S1. The vanadium-titanium ore is conveyed to the interior of the stirring and splicing silo 2 by a conveyor, and the stirring and splicing silo 2 guides the vanadium-titanium ore to fall into the spiral grinding column 3 and the spliced ​​grinding sieve plate 5.

[0058] S2, the reverse rotation device 6 drives the disassembly installation device 4 and the spiral grinding column 3 to rotate in the opposite direction synchronously. When the disassembly installation device 4 rotates, the spliced ​​grinding screen plate 5 will rotate accordingly. When the spliced ​​grinding screen plate 5 and the spiral grinding column 3 rotate, the vanadium-titanium ore material in the gap will be rotated. The rotating vanadium-titanium ore materials rotate and rub against each other, which will grind the vanadium-titanium ore materials into vanadium-titanium ore balls.

[0059] S3. When the size of the vanadium-titanium ore balls is worn to a suitable size, the vanadium-titanium ore balls will pass through the spliced ​​grinding sieve plate 5, which will screen the vanadium-titanium ore balls and effectively avoid the vanadium-titanium ore balls being ground too large. Qualified vanadium-titanium ore balls and smaller vanadium-titanium ore balls will pass through the spliced ​​grinding sieve and enter the dust reduction guide device 7, which can effectively guide the vanadium-titanium ore balls to fall into the separation and filtration device 8, and the dust reduction guide device 7 will perform dust reduction on the transported vanadium-titanium ore balls.

[0060] S4, the separation and filtration device 8 will classify and screen the manufactured vanadium-titanium ore balls, and the classification and screening will classify and process the smaller vanadium-titanium ore balls, grinding powder and dust-reducing water in the vanadium-titanium ore balls.

[0061] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
