Description

Technical Field

[0001] The present invention belongs to the technical field of ore screening, and in particular relates to a mineral processing device for screening ore quality. Background Art

[0002] Different qualities of ore not only differ in their physical and chemical properties, but also in their uses. Ore quality includes but is not limited to the following characteristics: 1. Complete structure: refers to the complete structure of the ore without obvious cracks or faults.

[0003] 2. High density: refers to the relatively large weight of the ore and its high density.

[0004] 3. Strong separability: refers to the fact that the ore can be separated from the ore matrix relatively easily, such as iron ore can be separated by magnetic adsorption.

[0005] 4. Strong and durable: refers to the ore has high hardness and strength, not easy to break or damage.

[0006] Therefore, when screening ores, they can be classified and screened according to the quality of different ores, so as to achieve the operation of screening the quality of the ore. Moreover, through pre-screening, the subsequent process steps such as crushing, grinding, and separation can be adjusted according to the specific quality of the ore, thereby improving the overall mineral processing efficiency and reducing processing costs.

[0007] For example, patent publication number CN106423551B, publication date 2017-08-25, discloses a device for removing iron from feldspar ores. The device performs beneficiation through an air separation chamber, a primary magnetic separation chamber, and a secondary magnetic separation chamber from top to bottom. However, the initial air separation step causes some smaller magnetic ores and non-magnetic ores to be air-separated together, which cannot be normally magnetically separated by the subsequent magnetic separation chambers.

[0038] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0039] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0040] A mineral processing device for screening ore quality, such as Figure 1-Figure 5As shown, the ore dressing frame 1 is made of a poor magnetic conductor, and a magnetic separation conveyor belt 2 is installed on the upper left part of the ore dressing frame 1. The magnetic separation conveyor belt 2 is suitable for conveying the ore to be screened from left to right into the ore dressing frame 1 and performing preliminary magnetic separation. The magnetic system of the magnetic separation conveyor belt 2 is located at the discharge end (right end) of the magnetic separation conveyor belt 2, and the magnetic angle notch of the magnetic separation conveyor belt 2 is facing the lower left. The ore dressing frame 1 is provided with a magnetic separation channel 1 31 located below the magnetic angle notch on the magnetic separation conveyor belt 2, and a magnetic separation channel 2 311 connected to the right side of the magnetic separation channel 1 31. When the magnetic ore magnetically separated at the discharge end of the magnetic separation conveyor belt 2 passes through the magnetic angle notch on the magnetic separation conveyor belt 2, the magnetic ore will separate from the magnetic separation conveyor belt 2 and fall into the magnetic separation channel 1 31. The magnetic separation channel 1 31 and the magnetic separation channel 1 31 are connected to the right side of the magnetic separation channel 1 31. A drum magnetic separation group 1 331 having a magnetic strength less than that of the magnetic separation conveyor belt 2 is installed at the position where the channel 2 311 is connected. The drum magnetic separation group 1 331 and the rotating shaft of the magnetic separation conveyor belt 2 are driven by a flat belt 81. The magnetic angle notch of the drum magnetic separation group 1 331 faces the lower right. In another feasible embodiment, the drum magnetic separation group 1 can also be driven by an external motor. In this embodiment, a gap is left above the drum magnetic separation group 1 331 in the mineral processing frame 1 for magnetic ore to be magnetically separated from the magnetic separation channel 1 31 to the magnetic separation channel 2 311. At this time, the drum magnetic separation group 1 331 runs clockwise for magnetic separation. In another embodiment, the gap can also be located below the drum magnetic separation group 1 331, but the drum magnetic separation group 1 331 needs to run counterclockwise for magnetic separation.The drum magnetic separation group 1 331 is suitable for magnetically separating the magnetic ore in the magnetic separation channel 1 31 into the magnetic separation channel 2 311. The drum magnetic separation group 1 331 will magnetically separate the magnetic ore with smaller mass and lower magnetism from the magnetic separation channel 1 31 into the magnetic separation channel 2 311, while the magnetic ore with larger mass and unable to be magnetically separated by the drum magnetic separation group 1 331 will be directly discharged from the bottom of the magnetic separation channel 1 31. In this way, the magnetic ore can be magnetically separated from the non-magnetic ore during the transportation process, and the magnetic separation channel 1 31 and the magnetic separation channel 2 311 can be classified and discharged. The ore dressing frame 1 also has a filter channel 1 32 close to the lower end of the discharge end of the magnetic separation conveyor belt 2, and a filter channel 2 321 connected to the right side of the filter channel 1 32. The non-magnetic ore discharged by the magnetic separation conveyor belt 2 will fall directly into the filter channel 1 32. One end of the filter arc plate 35 is connected below the position where the filter channel 1 32 and the filter channel 2 321 are connected. The other end of the filter arc plate 35 is connected to the other side of the filter channel 1 32. The left and right ends of the filter arc plate 35 are bent upward. A screen wheel 36 is provided on the filter channel 1 32 to contact the inner arc surface of the filter arc plate 35. The screen wheel 36 has a circle for screening different sizes. The mesh diameter of the screen wheel 36 is smaller than that of the filter arc plate 35. The smaller ore in the filter channel 1 32 will pass through the screen wheel 36 and the filter arc plate 35 and be discharged from the bottom of the filter channel 1 32. During this process, the external power source drives the screen wheel 36 to rotate counterclockwise, and the screen wheel 36 will push the larger ore from the filter channel 1 32 to the filter channel 2 321. In this way, the non-magnetic ore can be screened out from the magnetic ore during the transportation process, and the filter channel 1 32 and the filter channel 2 321 can be classified and discharged into non-magnetic ores of different sizes. The screening of the ore is first carried out with The ore is initially sorted by quality, either magnetic or non-magnetic. Two different types of magnetic ores are then discharged based on mass and magnetic strength, while two different types of non-magnetic ores are discharged based on volume. This ingenious and rational screening process prevents the discharge of magnetic ores with low mass and magnetism along with small non-magnetic ores. A barrier block 38 is connected to filter channel 1 32 . This barrier block 38 blocks the connection between filter channel 1 32 and filter channel 2 321 . This barrier block 38 prevents non-magnetic ores discharged from the magnetic separation conveyor belt 2 from falling directly into filter channel 2 321 without being filtered, ensuring effective filtration of ores of varying sizes.

[0041] like Figure 4As shown, a unloading plate 34 is also included. A unloading plate 34 is rotatably provided on the magnetic separation channel 31 of the ore dressing frame 1. The unloading plate 34 and the drum magnetic separation group 331 are respectively located on the left and right sides of the magnetic separation channel 31. The lower end of the unloading plate 34 is inclined toward the drum magnetic separation group 331, so that the magnetic ore falling into the magnetic separation channel 31 will be guided by the unloading plate 34 to be closer to the drum magnetic separation group 331, thereby improving the magnetic separation effect. Two front-to-back buffer springs 340 are connected between the lower side of the unloading plate 34 and the magnetic separation channel 31. On the basis of guiding the magnetic ore, the unloading plate 34 will also perform shock absorption and buffering on the falling magnetic ore under the action of the buffer spring 340 to avoid excessive collision damage. The magnetic ore with larger mass will first squeeze the unloading plate 34 to unload the force during the falling process, and then be discharged after the unloading plate 34 is rotated open under the force.

[0042] like Figure 4 As shown, it also includes a baffle plate 41. The baffle plate 41 is rotatably provided on the magnetic separation channel 131 of the ore dressing frame 1 and is located just above the unloading plate 134. The end of the baffle plate 41 is connected to a gear 132. A rack 133 is slidably provided on the ore dressing frame 1 and is meshed with the right side of the gear 132. The end of the unloading plate 134 is connected to a gear 244 that is meshed with the right side of the rack 132. The gear 132 and the gear 244 are respectively meshed on the left and right sides of the rack 132. When the magnetic ore falling is large and heavy, the unloading plate 132 is opened. When the force plate 1 34 rotates downward, the force unloading plate 1 34 will drive the rack 1 43 to move upward and engage with the gear 2 44 through the gear 2 44, and the gear 2 44 will drive the baffle plate 41 to rotate upward. In this way, the force unloading plate 1 34 not only unloads the force and guides the magnetic ore, but also automatically and synchronously makes the baffle plate 41 block part of the magnetic ore according to the falling amount of the magnetic ore, thereby preventing the phenomenon of blockage caused by too much material being unloaded at the same time, and also ensuring the effect of magnetic separation, with strong adaptability and improving the fault tolerance of the magnetic separation conveyor belt 2.

[0043] like Figure 6 and Figure 7As shown, it also includes a material stopper 45. The upper left part of the ore dressing frame 1 is slidably provided with a material stopper 45 located above the magnetic separation conveyor belt 2. The material stopper 45 is tilted and is suitable for smoothing the ore that is too high on the magnetic separation conveyor belt 2. The lower sides of the front and rear ends of the material stopper 45 are connected to rack 2 46. Rack 1 43 and rack 2 46 are respectively meshed with the left and right sides of gear 1 42. When the magnetic ore falling is large and heavy and the unloading plate rotates downward, the upward rotating material stopper 41 will drive rack 2 46 downward through gear 1 42, and rack 2 46 will drive the material stopper 45 to move down and closer to the magnetic separation conveyor belt 2. At this time, the ore on the magnetic separation conveyor belt 2 will be spread more evenly by the material stopper 45, so as to further reduce the subsequent working pressure of the drum magnetic separation group 1 331. The unloading plate 1 34 unloads force, guides magnetic ore, controls the discharge amount and spreads out evenly during transportation. Each step is related to and coordinated with each other.

[0044] like Figure 2 、 Figure 3 、 Figure 8 and Figure 9As shown, it also includes a drum magnetic separation group 2 332, the mineral processing frame 1 has a magnetic separation channel 3 50 connected to the magnetic separation channel 1 31, the magnetic separation channel 3 50 and the magnetic separation channel 2 311 are respectively connected to the left and right sides of the magnetic separation channel 1 31, and the drum magnetic separation group 2 332 located at the lower left of the drum magnetic separation group 1 331 is installed at the position where the magnetic separation channel 1 31 and the magnetic separation channel 3 50 are connected. The magnetic angle notch of the drum magnetic separation group 2 332 faces the lower left. The drum magnetic separation group 1 in the mineral processing frame 1 A gap is left above the selection group 2 332 for magnetic ore to be magnetically separated from the magnetic separation channel 1 31 to the magnetic separation channel 3 50. The drum magnetic separation group 2 332 will perform secondary subdivision magnetic separation on the magnetic separation ore in the magnetic separation channel 1 31 that has passed through the drum magnetic separation group 1 331. The drum magnetic separation group 2 332 and the drum magnetic separation group 1 331 cooperate to perform magnetic separation on the left and right sides of the magnetic separation channel, thereby improving the effect of magnetic separation and avoiding omission. The magnetic separation channel 3 50 is connected with a rear end inclined backward and downward. The inclined plate 1 51 is in contact with the inclined plate 1 51, and the inclined plate 1 51 is suitable for receiving the magnetic ore magnetically separated from the drum magnetic separation group 2 332. The mineral processing frame 1 is connected with a guide plate 1 52 located between the inclined plate 1 51 and the magnetic separation channel 2 311. The guide plate 1 52 is used to guide the magnetic ore on the inclined plate 1 51 to the magnetic separation channel 2 311, so that the magnetic ore with smaller mass and smaller magnetism magnetically separated by the drum magnetic separation group 2 332 and the drum magnetic separation group 1 331 can be discharged from the magnetic separation channel 2 311 together, which achieves the effect of convenient collection on the basis of double magnetic separation; the drum magnetic separation group 2 332 and the drum magnetic separation group 1 331 are both connected with a large gear 82, and the mineral processing frame 1 is rotatably provided with two meshing small gears 83, and the two small gears 83 are respectively meshed on the side of the two large gears 82 close to each other, so that when the drum magnetic separation group 1 331 rotates clockwise, it can automatically drive the drum magnetic separation group 2 332 to rotate counterclockwise.

[0045] like Figure 3 As shown, it also includes a unloading plate 2 37. Two unloading plates 2 37 are rotatably provided on the filter channel 1 32 of the mineral processing frame 1, and are opposite to each other. The right unloading plate 2 37 is located directly above the blocking block 38. A buffer spring 2 370 is connected between the lower side of the unloading plate 2 37 and the filter channel 1 32. The unloading plate 2 37 will shock and buffer the falling non-magnetic ore under the action of the buffer spring 2 370 to avoid excessive collision damage. During the falling process, the non-magnetic ore will first squeeze the unloading plate 2 37 to unload the force, and then be discharged to the filter arc plate 35 and the screen wheel 36 for filtration after the unloading plate 2 37 is rotated open under the force.

[0046] like Figure 3 and Figure 8 and Figure 10As shown, a filter baffle 61 is also included. A secondary filter port is opened between the second filter channel 321 and the first filter channel 32, and is located below the right end of the filter arc plate 35. A filter baffle 61 is provided on the side of the second filter channel 321 close to the first filter channel 32, and is located above the secondary filter port. A resistance plate 62 is provided on the filter baffle 61, which contacts the mineral processing frame 1. A space is left between the resistance plate 62 and the filter baffle 61 for the ore to pass through the secondary filter port. When the screen wheel 36 rotates counterclockwise to push the filtered ore into the second filter channel 321, the filter baffle 61 will perform a secondary filter on the ore in the second filter channel 321. The smaller ore missed in the first filtration will pass through the left filter baffle 61 and fall onto the resistance plate 62 and be discharged from the left secondary filter port to the bottom of the filter arc plate 35 in the filter space one. In this way, the discharge and collection operation of smaller ores is facilitated on the basis of secondary filtration, thereby improving the filtering effect.

[0047] like Figure 2 、 Figure 3 and Figure 13 As shown, it also includes an elastic reset group 63, the mineral processing frame 1 has a filter channel three 70, and a secondary filter port is also opened between the filter channel three 70 and the filter channel one 32. There are two filter baffles 61, and the two filter baffles 61 are respectively close to the filter channel one 32 and the filter channel three 70. The filter baffle 61 is rotatably arranged in the filter channel two 321. The contact plates 62 on the two filter baffles 61 are all rotated with the filter baffle 61, and a torsion spring is connected between the contact plate 62 and the filter baffle 61 (in order to simplify the view and highlight the key parts, the torsion spring is not specifically marked and illustrated in the drawings, but those skilled in the art will understand it according to the context and the present invention). Figure 15It is easy to understand and implement this solution); an elastic reset group 63 is provided on the mineral processing frame 1, and the elastic reset group 63 is used to assist the two filter baffles 61 to adaptively open and close according to the gravity of the ore. The two filter baffles 61 work on the same principle, and the two filter baffles 61 temporarily intercept the ore, thereby improving the filtering time and filtering effect. When the ore on the two filter baffles 61 presses the filter baffles 61 to rotate downward, the filter baffle 61 will squeeze the resistance plate 62, and the resistance plate 62 will adaptively rotate along the mineral processing frame 1 under the action of the torsion spring, thereby automatically opening the filter baffle 61 to discharge the larger ore that cannot be filtered out for the second time, and then the elastic reset group 63 will cause the two filter baffles 61 to rotate in the opposite direction and reset to continue the secondary filtering operation; the resistance plate 62 near the filter channel three 70 There is also space left between the filter baffle 61 for the ore to flow into the filter channel three 70 through the secondary filter port. The filter channel three 70 is connected to an inclined plate 2 71 with its rear end tilted backward and downward. The mineral processing frame 1 is connected to a guide plate 2 73 located between the inclined plate 2 71 and the filter channel one 32. The smaller ores that pass through the right filter baffle 61 will fall onto the resistance plate 62 and be discharged from the secondary filter port on the right to the inclined plate 2 71 in the filter space three. The guide plate 2 73 is used to guide the non-magnetic ore on the inclined plate 2 71 to the bottom of the filter arc plate 35 in the filter channel two 321. In this way, on the basis of adding a second filter baffle 61 to increase the filter area and temporarily intercept the ore, the smaller filtered ores can finally be discharged from the filter channel two 321 together for easy collection and processing.

[0048] like Figure 2 、 Figure 13 、 Figure 14 and Figure 15 As shown, the elastic reset group 63 includes an L-shaped rod 631, and the front and rear ends of the two filter baffles 61 are connected with the L-shaped rod 631. Two sliding frames 633 that are opposite to each other and respectively surround the L-shaped rods 631 on the front and rear sides are sliding on the mineral processing frame 1. When the ore on the two filter baffles 61 presses the filter baffle 61 to rotate downward and open, the filter baffle 61 will drive the L-shaped rod 631 to rotate and pry up the sliding frame 633. Two left and right opposite reset springs 634 are connected between the sliding frame 633 and the mineral processing frame 1. After the ore leaves the filter baffle 61, the reset spring 634 is used to reset the upward sliding frame 633. The sliding frame 633 will move downward and squeeze the L-shaped rod 631 to drive the filter baffle 61 to rotate upward and reset.

[0049] like Figure 2 and Figure 14As shown, a shift block 635 is also included. The mineral processing frame 1 is slidably provided with a shift block 635 that contacts and cooperates with the lower side of the sliding frame 633 (in order to simplify the view and highlight the key parts, the positional relationship of the sliding cooperation between the shift block 635 and the mineral processing frame 1 is not specifically marked and illustrated in the drawings, but the connection relationship can be any connection relationship that enables the shift block 635 to slide up and down, for example: using a guide rail connected to the mineral processing frame 1, or providing a slide groove on the mineral processing frame 1 for the shift block 635 to slide), the shift block 635 is L-shaped, and a connecting rod 636 is rotatably provided between the eccentric left end of the screen wheel 36 and the upper part of the shift block 635, and the end (right end) of the connecting rod 636 close to the shift block 635 is higher than the end (left end) close to the screen wheel 36, so that when the screen wheel 36 rotates clockwise to push larger ores into the filtering channel 2 321 The filter baffle 61 is rotated and reset upwards by the L-shaped rod 631 to continue filtering the ore. In this way, the filter baffle 61 is automatically and synchronously opened and closed intermittently to discharge ore of different sizes when filtering ores. The upward movement of the sliding frame 633 is not forcibly affected by the dial block 635. Even if the dial block 635 does not move up, when there are more large ores, the filter baffle 61 can still be rotated and opened downwards to ensure the normal circulation of the ore.

[0050] like Figure 2 、 Figure 11 and Figure 12 The cam 352 is actuated to move the filter element 351 so as to adjust the filter element 351 so as to adjust the filter element 351 to a desired size.

[0052] It should be pointed out that, for ordinary technicians in this field, several variations, increases and decreases in quantity, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
