Description

Technical Field

[0001] The present invention relates to the technical field of mineral processing shaking tables, and in particular to a mineral processing shaking table, a zircon sand production line and a processing method. Background Art

[0002] Zircon sand raw ore is dried and dry-magnetically separated to obtain zircon sand ore, which is then ground to obtain zircon mortar. The zircon mortar needs to be separated by shaking table water separation to obtain concentrate and tailings. The concentrate then needs to be dried, dry-magnetically separated, electrostatically separated, and subjected to high-intensity magnetic separation to extract zirconium products and monazite.

[0003] After water separation on a shaking table, the concentrate is in a slurry-like state and contains a large amount of water. It usually needs to be dried through sedimentation, pumping, screening, and drying / airing in sequence before it can be used for magnetic separation. This type of operation requires a lot of time and results in reduced production efficiency. Summary of the Invention

[0004] In order to overcome the problem in the above background technology that "drying concentrate slurry requires a lot of time, resulting in reduced overall production efficiency", the present invention provides a mineral processing shaking table, a zircon sand production line and a processing method.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] The ore dressing shaking table comprises a bed plate, a bottom support module and a side support module; the upper surface of the bed plate is provided with bed bars; the bed plate is provided with a feeding end and a discharging end; the feeding end is provided with a water hopper and a ore feeding hopper; the discharging end is provided with a material receiving assembly, and the material receiving assembly includes a concentrate box, a middling box and a tailings box; the bottom support module is fixedly mounted on the lower surface of the bed plate; the side support module comprises a cross support arm for supporting the concentrate box, the end of the cross support arm close to the bed plate is provided with a first slot, and the end away from the bed plate is provided with a second slot; a water-permeable structure is provided at the bottom of the concentrate box; the concentrate box can be selectively inserted into the first slot or the second slot; the concentrate end of the bed plate is provided with a lower bent portion in the form of a plate; the lower bent portion can laterally abut the concentrate box inserted into the first slot to prevent it from swinging; the bed plate and the cross support arm can move back and forth to drive the concentrate box inserted into the second slot to swing to drain the moisture in the concentrate.

[0007] As a further optimization scheme of the present invention, the concentrate box includes a box body, a first rotating shaft and a second rotating shaft; the first rotating shaft and the second rotating shaft are coaxially arranged and are respectively fixedly connected to the two end surfaces of the box body vertically, the first rotating shaft can be selectively inserted into the first card slot or the second card slot, and the second rotating shaft can be selectively inserted into the first card slot or the second card slot.

[0008] As a further optimization scheme of the present invention, the box body includes an abutment vertical plate, a counterweight arc plate and an end plate fixedly connected to each other; the abutment vertical plate can be adapted to fit and abut laterally with the lower bent portion; the counterweight arc plate is placed at the bottom end of the abutment vertical plate, and the middle part of the abutment vertical plate is equal to the height of the first rotating shaft.

[0009] As a further optimization solution of the present invention, the abutting vertical plate and the counterweight arc plate are connected in a U shape.

[0010] As a further optimization solution of the present invention, the counterweight arc plate is provided with water-permeable holes.

[0011] As a further optimization scheme of the present invention, the side support module also includes an inner support beam; the bottom support module and the downward bent part are arranged on both sides of the inner support beam, and the two side walls of the inner support beam are respectively adapted to fit and fixedly connected with the downward bent part and the inner support beam; both ends of the inner support beam are located outside the upper projection range of the bed board, and the end of the cross support arm is fixedly connected to the end of the inner support beam through a number of diagonal support rods.

[0012] As a further optimization scheme of the present invention, the inner support beam is an arc-shaped structure with a convex middle part, and the diagonal support rod is tilted upward at one end close to the transverse support arm and tilted downward at one end close to the inner support beam, thereby guiding the middle ore slurry dripping from the middle ore end of the bed plate into the middle ore box.

[0013] As a further optimization solution of the present invention, it also includes a transverse driving module for driving the bed board to move back and forth.

[0014] Zircon sand production line includes a beneficiation shaking table, a grinding module and a drying module.

[0015] The zircon sand processing method, that is, the steps of processing zircon sand using a zircon sand production line include: S1, using a grinding module to grind zircon sand ore to obtain zircon mortar; S2, using the mineral processing shaking table to sort the zircon mortar to obtain concentrate, and draining the concentrate to obtain drained concentrate; S3, drying the drained concentrate to obtain dried concentrate. Step S2 further includes the following steps: S21, take an empty concentrate box and define it as concentrate box a, and insert the concentrate box a into the first slot; S22, inject clean water and zircon mortar into the water hopper and the ore hopper respectively; S23, start the horizontal drive module, and the concentrate dripping from the concentrate end of the bed plate falls into the concentrate box a; S24, close the horizontal drive module, take the concentrate box a out of the first slot and insert it into the second slot; take another empty concentrate box and define it as concentrate box b, and insert the concentrate box b into the first slot; S25, start the horizontal drive module; the concentrate dripping from the concentrate end of the bed plate falls into the concentrate box b; the concentrate box a swings and drains the internal moisture to obtain drained concentrate.

[0016] In summary, the present invention has at least one of the following advantages:

[0017] (1) The present invention has a simple structure and reliable functions. When the bed plate moves back and forth to separate the concentrate, it can simultaneously drive the concentrate box to swing. The swinging of the bottom end of the concentrate box can throw out the water adhering to the concentrate in the inner cavity, thereby achieving rapid drainage of the concentrate. The centrifugal force and inertia generated during the swinging can achieve a better drainage effect and minimize the moisture in the drained concentrate. The drained concentrate can be directly dried in the sun or in the oven without the need for sedimentation, pumping, and screening operations in traditional technologies. The operation steps can be simplified, the drainage time and the sorting time can be overlapped, and the efficiency of the processing operation can be improved.

[0018] (2) The cross brace is used to support the concentrate box, which can be selectively inserted into the first slot or the second slot at the top of the cross brace. When the concentrate box is inserted into the first slot, the lower bend fits against the side wall of the concentrate box and no gap for leakage is generated between the two. At the same time, the concentrate box is prevented from swinging, so that the concentrate dripping from the concentrate end can fall into the concentrate box as much as possible, avoiding unnecessary loss of materials. When the concentrate box is inserted into the second slot, driven by the bed plate and the cross brace, the concentrate box can swing around the bottom end of the second slot, thereby shaking out the internal moisture.

[0019] (3) After the concentrate box in the first slot collects a certain amount of concentrate, the user lifts the concentrate box and inserts it into the second slot for draining, and then takes a new concentrate box and inserts it into the first slot to collect the concentrate. The operation is simple, and a cyclic operation can be realized with a short downtime, thereby ensuring high production and processing efficiency.

[0020] (4) The inner support beam can support the lower bend from the inside, preventing the concentrate box from pressing against the lower bend due to inertia, causing deformation of the lower bend, and further avoiding the problem of slurry leakage between the concentrate box and the lower bend. At the same time, the inner support beam can also support the cross bracing arm.

[0021] (5) The inner support beam is in an arc-shaped structure with an upward convex middle portion, thereby preventing the medium ore slurry from flowing along the inner support beam to the bottom of the bed plate; the end of the transverse support arm and the end of the inner support beam are connected by a plurality of diagonal support rods, and the diagonal support rods are arranged to be tilted upward at one end close to the transverse support arm and tilted downward at one end close to the inner support beam, thereby preventing the medium ore slurry from flowing to the transverse support arm position; finally, the medium ore slurry is diverted into the medium ore box to avoid material loss.

[0040] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0041] Reference Figures 1 to 3 This embodiment provides a mineral processing shaking table comprising a bed plate 1, a bottom support module 2, and side support modules 3. The bed plate 1 supports and separates zircon mortar; the bottom support module 2 supports the bed plate 1 while preventing it from bending and deforming, ensuring its flatness. The side support modules 3 drain the concentrate, which is then directly dried, significantly reducing drying time and improving production and processing efficiency.

[0042] Reference Figures 1 and 2 The upper surface of the bed plate 1 is provided with multiple, parallel bed bars 11, extending along the length of the bed plate 1. Adjacent bed bars 11 form a feed trough for sorting, where zircon sand particles of varying sizes and densities are separated into separate layers. As the zircon sand particles travel along the feed trough, they are impacted by water flow, achieving sorting. This is standard industry practice and will not be further elaborated.

[0043] Reference Figures 1 and 2A feed end and a discharge end are provided at the edge of the bed plate 1. The height of the side where the feed end is located is slightly higher than the side where the discharge end is located (that is, the bed plate 1 is tilted, and the tilt angle is usually 2 degrees to 8 degrees), so that the zircon mortar can flow from the feed end to the discharge end. A water supply hopper 12 and an ore feeding hopper 13 are provided at the feed end. The water supply hopper 12 is fixedly connected to the upper surface of the bed plate 1 (for example, by welding or by bolts), and the ore feeding hopper 13 is fixedly connected to the upper surface of the bed plate 1 (for example, by welding or by bolts). A diverter trough 121 is provided on the side of the water supply hopper 12 away from the ore feeding hopper 13. The diverter trough 121 is fixedly connected to the upper surface of the bed plate 1 (for example, by welding or by bolts); the diverter trough 121 is communicated with the water supply hopper 12, and a strip-shaped water outlet is provided at the bottom of the diverter trough 121 to discharge a flat water flow. A dilution tank 131 is provided between the water feed hopper 12 and the ore feed hopper 13. The dilution tank 131 is fixedly connected to the upper surface of the bed plate 1 (for example, by welding or bolting). The dilution tank 131 is communicated with the ore feed hopper 13. A strip-shaped slurry outlet hole is provided at the bottom of the dilution tank 131 to discharge a flat slurry flow.

[0044] Reference Figures 1 and 2 The discharge end includes a concentrate end 101, a middling end 102 and a tailings end 103, which are used to discharge concentrate, middling and tailings respectively; the concentrate end 101, the middling end 102 and the tailings end 103 are arranged in an L shape; the concentrate end 101 is arranged on the short side of the bed plate 1, the middling and tailings are arranged on the long side of the bed plate 1, and the middling is arranged between the concentrate and the tailings; all of them are conventional existing technologies in the industry and will not be described in detail.

[0045] Reference Figures 1 and 2 A material receiving assembly 14 is provided at the discharge end, and the material receiving assembly 14 includes a concentrate box 141, a middling box 142 and a tailings box 143; the positions of the concentrate box 141, the middling box 142 and the tailings box 143 are respectively adapted to the positions of the concentrate end 101, the middling end 102 and the tailings end 103, so as to respectively receive the dripping concentrate, middling and tailings.

[0046] Reference Figures 3 to 5The bottom support module 2 is fixedly mounted on the lower surface of the bed board 1. The bottom support module 2 includes a first support beam 21 and a second support beam 22. There are a plurality of first support beams 21 and they are arranged parallel to each other. There are a plurality of second support beams 22 and they are arranged parallel to each other. The first support beams 21 and the second support beams 22 are arranged perpendicular to each other and form a grid-like support structure, thereby supporting the bed board 1. The bed board 1 is planar; the first support beam 21 is arranged along the short side of the bed board 1, and the second support beam 22 is arranged along the long side of the bed board 1; the top surface of the first support beam 21 and the bottom surface of the bed board 1 are in contact with each other and fixedly connected (for example, by bolts or welding), and the bottom surface of the first support beam 21 and the top surface of the second support beam 22 are in contact with each other and fixedly connected (for example, by bolts or welding). The first support beam 21 and the second support beam 22 are both rectangular tube structures.

[0047] Reference Figures 3 to 5 The side support module 3 includes a cross-bracing arm 31 for supporting the concentrate box 141. Two cross-bracing arms 31 are provided and arranged parallel to each other, one on either side of the bed board 1. The cross-bracing arms 31 are arranged parallel to the bed board 1. One end of the cross-bracing arm 31 is close to the bed board 1, and the other end is away from the bed board 1. The cross-bracing arm 31 is arranged along the length of the bed board 1, and the ends of the cross-bracing arms 31 are connected to the ends of the bed board 1.

[0048] Reference Figures 3 to 5 The top of the cross bracing arm 31 is provided with a first slot 311 at the end near the bed board 1, and a second slot 312 at the end away from the bed board 1. The first slots 311 on the two cross bracing arms 31 are mutually adapted; the second slots 312 on the two cross bracing arms 31 are mutually adapted; when the two ends of the concentrate box 141 are respectively engaged in the two first slots 311, the length direction of the concentrate box 141 is parallel to the width direction of the bed board 1; when the two ends of the concentrate box 141 are respectively engaged in the two second slots 312, the length direction of the concentrate box 141 is parallel to the width direction of the bed board 1.

[0049] Reference Figures 3 to 5 The concentrate box 141 can be selectively inserted into the first slot 311 or the second slot 312. When inserted into the first slot 311, the concentrate box 141 cannot swing, thereby stably receiving the fallen concentrate. When inserted into the second slot 312, the concentrate box 141 can swing back and forth with the reciprocating movement of the bed plate 1, thereby shaking out moisture adhering to the concentrate inside the concentrate box 141.

[0050] Reference Figures 3 to 5The bed plate 1 has a lower bent portion 10 at the end where the concentrate end 101 is located, which is arranged perpendicular to the bed plate 1. The lower bent portion 10 is a vertical strip-shaped structure. The lower bent portion 10 can laterally abut the concentrate box 141 inserted into the first slot 311 to prevent it from swinging. The bed plate 1 and the cross brace 31 can synchronously reciprocate and move horizontally, thereby driving the concentrate box 141 inserted into the second slot 312 to swing, thereby draining moisture from the concentrate in the inner cavity of the concentrate box 141.

[0051] Reference Figure 6 and Figure 7 The concentrate box 141 includes a box body 1411, a first rotating shaft 1412, and a second rotating shaft 1413. The first rotating shaft 1412 and the second rotating shaft 1413 are coaxially arranged and fixedly connected to the two end surfaces of the box body 1411 at right angles. The first rotating shaft 1412 can selectively engage with the first engaging slot 311 or the second engaging slot 312, and the second rotating shaft 1413 can selectively engage with the first engaging slot 311 or the second engaging slot 312. The first rotating shaft 1412 and the second rotating shaft 1413 can respectively engage with the first engaging slot 311 of the two cross-bracing arms 31 or the second engaging slot 312 of the two cross-bracing arms 31.

[0052] Reference Figure 6 and Figure 7 The box body 1411 includes a mutually fixedly connected abutting upright plate 14111, a counterweight arc plate 14112, and an end plate 14113. The abutting upright plate 14111 can fit and abut the lower curved portion 10 horizontally, thereby preventing the box body 1411 from swinging and preventing a gap from leaking between the two. The counterweight arc plate 14112 is placed at the bottom of the abutting upright plate 14111, and the middle of the abutting upright plate 14111 is at the same height as the first rotating shaft 1412. The bottom end of the concentrate box 141 is heavier than the top end, so that the concentrate box 141 swings under the push of the bed plate 1 instead of rotating 360 degrees, thereby preventing the concentrate in the inner cavity of the concentrate box 141 from falling out.

[0053] Reference Figure 6 and Figure 7 , the abutting vertical plate 14111 is connected to the counterweight arc plate 14112 in a U-shape. The counterweight arc plate 14112 is in the shape of an arc plate with a concave middle part. The abutting vertical plate 14111 is in the shape of a straight plate, and there are two abutting vertical plates 14111 that are arranged parallel to each other; the bottom ends of the two abutting vertical plates 14111 are respectively tangent to the two ends of the counterweight arc plate 14112 and fixedly connected (for example, fixedly connected by welding or fixedly connected in an integrated manner). The middle and upper edge of the end plate 14113 is adapted and fixedly connected to the end of the abutting vertical plate 14111 (for example, fixedly connected by bolts or fixedly connected by welding), and the bottom edge of the end plate 14113 is adapted and fixedly connected to the top end of the counterweight arc plate 14112 (for example, fixedly connected by bolts or fixedly connected by welding).

[0054] The bottom of the concentrate box 141 is equipped with a permeable structure, such as a permeable hole or a filter cotton layer. The permeable hole is located on the counterweight arc plate 14112. The counterweight arc plate 14112 includes an edge frame and a metal mesh. The edge frame is positioned at the outer edge of the metal mesh and fixedly connected (for example, by welding or by using pressure strips and bolts). The permeable hole is located between the wires of the metal mesh. Moisture mixed with the concentrate in the concentrate box 141 is drained through the permeable hole.

[0055] Reference Figures 3 to 6 The side support module 3 also includes an inner support beam 32. The bottom support module 2 and the lower curved portion 10 are disposed on either side of the inner support beam 32. The side walls of the inner support beam 32 respectively fit snugly with and are fixedly connected to the lower curved portion 10 and the inner support beam 32. The inner support beam 32 is fixedly connected to the side walls of the lower curved portion 10 by welding or by fasteners and bolts. The inner support beam 32 is also fixedly connected to the end face of the second support beam 22 (e.g., by welding or bolts), thereby securing the inner support beam 32. The inner support beam 32 is used to apply a lateral support force to the lower bent portion 10 to prevent the lower bent portion 10 from bending inward (i.e., in the direction of the bottom support module 2) (during the reciprocating horizontal movement of the bed board 1, under the action of inertia, the concentrate box 141 inserted in the first slot 311 will repeatedly press the lower bent portion 10 laterally, causing the lower bent portion 10 to have a tendency to bend inward), further avoiding the occurrence of a slurry leakage gap between the concentrate box 141 and the lower bent portion 10 (after the lower bent portion 10 bends inward, the lower bent portion 10 and the abutting vertical plate 14111 are no longer in contact, resulting in a slurry leakage gap), further avoiding the problem of concentrate leaking from the slurry leakage gap instead of entering the concentrate box 141.

[0056] Reference Figure 3 Both ends of the inner support beam 32 are located outside the upper projection range of the bed board 1, that is, both ends of the inner support beam 32 extend from directly below the bed board 1, thereby being used to connect with the cross bracing arms 31. The two cross bracing arms 31 are respectively and vertically fixedly connected to the two ends of the inner support beam 32, and the inner support beam 32 provides structural support for the cross bracing arms 31.

[0057] Reference Figure 3 and Figure 8 The ends of the cross bracing arms 31 and the ends of the inner support beams 32 are fixedly connected by a plurality of diagonal bracing rods 313. A triangular support structure is formed between adjacent diagonal bracing rods 313, thereby improving the connection force between the cross bracing arms 31 and the inner support beams 32 and improving the structural stability.

[0058] Reference Figure 3 、 Figure 8 and Figure 9The inner support beam 32 is an arc-shaped structure with a convex center. The diagonal support rod 313 is tilted upward at one end near the cross support arm 31 and tilted downward at the other end near the inner support beam 32, thereby guiding the middle ore slurry dripping from the middle ore end 102 of the bed plate 1 into the middle ore box 142. The middle ore box 142 is located below the end of the inner support beam 32 near the discharge end.

[0059] Reference Figure 9 The inner support beam 32 has an arc-shaped structure with an upwardly convex middle portion. The upper surface of the inner support beam 32 end portion is inclined, allowing the intermediate ore (i.e., intermediate ore slurry, in slurry form) dripping from the intermediate ore end 102 to fall onto the upper surface of the inner support beam 32 end portion and then further drip into the intermediate ore box 142. This prevents the intermediate ore slurry from flowing along the upper surface of the inner support beam 32 directly under the bed plate 1. If the intermediate ore slurry flows directly under the bed plate 1 (for example, in the middle of the inner support beam 32), it will drip onto the floor of the processing workshop, causing unnecessary material loss.

[0060] Reference Figure 8 Since the side where the discharge end of the bed plate 1 is located is tilted downward, and the end of the cross brace arm 31 close to the bed plate 1 is tilted upward, the diagonal support rod 313 is used to prevent the medium ore pulp adhering to the surface of the inner support beam 32 from flowing in the direction of the cross brace arm 31. If the medium ore pulp flows diagonally downward along the length direction of the cross brace arm 31, it will eventually drip at the end of the cross brace arm 31 away from the bed plate 1 (dripping on the ground of the processing workshop or falling into the waste pulp tank 15), causing unnecessary loss of material. In the present invention, the diagonal support rod 313 is tilted upward at one end close to the cross brace arm 31 and tilted downward at one end close to the inner support beam 32, so that the medium ore pulp cannot flow upward from the bottom end of the diagonal support rod 313 to the top end of the diagonal support rod 313, and thus cannot contact the cross brace arm 31.

[0061] Reference Figure 2 and Figure 10 The intermediate ore box 142 is located below the intermediate ore end 102, and the tailings box 143 is located below the tailings box 143. The concentrate box 141, intermediate ore box 142, and tailings box 143 all have a box-like structure with an open top. The top opening of the concentrate box 141 is equipped with an openable and closable cover, the edge of which is detachably connected to the top surface of the end plate 14113 (for example, by a spring buckle, elastic clip, or bolts). When the concentrate box 141 needs to be swung for drainage, the cover is installed in advance at the top opening of the concentrate box 141 to prevent the concentrate particles inside from accidentally splashing out when the concentrate box 141 is swung.

[0062] Reference Figure 2 and Figure 10A waste slurry trough 15 is provided below the material receiving assembly 14. The waste slurry trough 15 is in an L-shaped structure to adapt to the concentrate box 141, the middling box 142 and the tailings box 143 arranged in an L-shape; the concentrate box 141 is suspended above the waste slurry trough 15 by a horizontal support arm 31; the middling box 142 and the tailings box 143 are pressed onto the top surface of the side plate of the waste slurry trough 15 and fixedly connected (for example, by bolts or welding); the waste slurry trough 15 is used to receive the waste slurry flowing out from the edge of the bed plate 1 at the non-discharge end position.

[0063] Reference Figure 3 and Figure 10 The width L of the waste slurry trough 15 below the concentrate box 141 matches the length of the cross arm 31, so that the concentrate box 141 can be located directly above the concentrate box 141 regardless of whether it is inserted into the first slot 311 or the second slot 312. In addition, when the concentrate box 141 is inserted into the second slot 312 and swings, the water ejected can drip into the waste slurry trough 15. The waste slurry trough 15 is placed on the floor of the processing workshop.

[0064] Reference Figure 11 A reinforcement rod 314 is connected to the bottom end of the inner support beam 32. The reinforcement rod 314 is tilted upward, with the end near the cross-bracing arm 31 tilted upward and the end near the inner support beam 32 tilted downward. The reinforcement rod 314 is straight. One end of the reinforcement rod 314 is fixedly connected to the bottom of the inner support beam 32 (e.g., by bolts or welding), and the other end is fixedly connected to the middle of the outer wall of the cross-bracing arm 31 (e.g., by bolts or welding). This forms a triangular support structure, enhancing the load-bearing capacity of the cross-bracing arm 31 and preventing overload and disengagement at the connection between the cross-bracing arm 31, the inner support beam 32, and the diagonal bracing rod 313, leading to failure.

[0065] Reference Figure 1 A water retaining plate 16 is provided at the end of the bed plate 1 away from the discharge end. Water retaining plate 16 is connected to the outer wall of the feed hopper 13 (e.g., by bolts or welding). Water retaining plate 16 is vertically positioned on the upper surface of the bed plate 1 and is fixedly connected to the bed plate 1 (three-dimensionally by welding or bolts). Water retaining plate 16 is used to prevent the zircon mortar from accidentally flowing out of the end of the bed plate 1 away from the discharge end.

[0066] Reference Figure 6The second rotating shaft 1413 is sleeved and fixed with a limiting sleeve 1414 (for example, fixedly connected by bolts); the distance between the limiting sleeve 1414 and the two end faces of the box body 1411 away from each other is adapted to the spacing between the two cross bracing arms 31, that is, when the concentrate box 141 is inserted into the first slot 311 or the second slot 312, the end face of the limiting sleeve 1414 away from the box body 1411 is in contact with one of the side walls of the cross bracing arms 31, and the end face of the box body 1411 away from the limiting sleeve 1414 is in contact with the side wall of the other cross bracing arm 31, thereby limiting the box body 1411 to a position close to the concentrate end 101, preventing the box body 1411 from sliding along the width direction of the bed plate 1, further improving the hit rate of receiving materials (receiving concentrate), and preventing the first rotating shaft 1412 from falling out of the first slot 311 / second slot 312.

[0067] The mineral processing shaking table also includes a transverse drive module for driving the bed plate 1 to move back and forth, and a bed frame for supporting the bottom support module 2; the bed frame and the bottom support module 2 are connected by a sliding guide structure (such as a slide rail structure) or a rolling guide structure, thereby facilitating the relative movement of the bottom support module 2 and the bed frame; the fixed seat of the transverse drive module is fixedly connected to the floor of the processing workshop or the bed frame (for example, by bolts), and the output shaft is fixedly connected to the bottom support module 2 (the first support beam 21 or the second support beam 22) (for example, by bolts), and the transverse drive module is capable of driving the bottom support module 2 and the bed plate 1 to move laterally synchronously. The transverse drive module adopts, for example, a cam lever headstock, an eccentric connecting rod headstock, or a spring headstock, which are conventional existing technologies in the industry and will not be described in detail.

[0068] The slide rail structure consists of a slider and a rail. The slider has a C-shaped cross-section, while the rail has a gourd-shaped cross-section. The slider is fastened to the rail to prevent it from falling off; the slider can slide back and forth along the length of the rail. The slider is fixedly connected to the base support module 2 via bolts, while the rail is also fixedly connected to the bed frame via bolts. The length of the rail is parallel to the length of the bed board 1; the transverse drive module can drive the bed board 1 to move back and forth along the length of the rail.

[0069] The rolling guide structure includes a track and rollers. The track has an equilateral triangle cross-section, and the rollers have an annular groove on their circumference. The track is bolted to the bed frame, while the rollers are rotatably mounted on the underside of the base support module 2 via bearings and bearing seats. The rollers are pressed against the track, with the top tips of the tracks inserted into the annular grooves. The rollers are capable of rolling along the length of the track. The length of the track is parallel to the length of the bed board 1, and the transverse drive module is capable of driving the bed board 1 to move back and forth along the length of the track.

[0070] The zircon sand production line includes a beneficiation shaker, a grinding module, and a drying module. The grinding module utilizes equipment such as ball mills, rod mills, pebble mills, autogenous mills, and vibrating mills, all of which are conventional in the industry and will not be described in detail. The drying module, such as a drying chamber, also utilizes conventional in the industry and will not be described in detail.

[0071] The zircon sand processing method, that is, the steps of processing zircon sand using a zircon sand production line include:

[0072] S1. Grind zircon sand ore using a grinding module to obtain zircon mortar (add water during or after grinding to form a slurry).

[0073] S2. Using a mineral processing shaker to separate the zircon mortar to obtain concentrate, and draining the concentrate to obtain drained concentrate.

[0074] S3, drying the drained concentrate to obtain dried concentrate.

[0075] Step S2 further includes the following steps:

[0076] S21 . Take an empty concentrate box 141 and define it as concentrate box a141a . Insert the concentrate box a141a into the first slot 311 .

[0077] S22. Inject clean water and zircon mortar into the water hopper 12 and the ore hopper 13 respectively.

[0078] S23, start the transverse driving module, and the concentrate dripping from the concentrate end 101 of the bed plate 1 falls into the concentrate box a141a.

[0079] S24, when a certain amount of concentrate is collected in the concentrate box a141a, the horizontal drive module is turned off, the concentrate box a141a is taken out from the first slot 311 and inserted into the second slot 312; another empty concentrate box 141 is defined as concentrate box b141b, and the concentrate box b141b is inserted into the first slot 311 (refer to Figure 3 ).

[0080] S25, start the transverse drive module; the concentrate dripping from the concentrate end 101 of the bed plate 1 falls into the concentrate box b141b; the bed plate 1 and the cross brace arm 31 drive the concentrate box a141a to swing during the reciprocating movement, and the concentrate box a141a drains the internal water during the swing process to obtain the drained concentrate (reference Figure 3 ).

[0081] The present invention has a simple structure and reliable function. The reciprocating horizontal movement of the bed plate 1 to separate the concentrate simultaneously drives the concentrate box 141 to swing. The swinging bottom of the concentrate box 141 can remove moisture adhering to the concentrate in the inner cavity, thereby achieving rapid drainage of the concentrate. The drained concentrate can be directly sun-dried or oven-dried, eliminating the need for sedimentation, pumping, and screening required by traditional techniques. This simplifies the operation steps and improves processing efficiency.

[0082] The cross brace 31 is used to support the concentrate box 141, and the concentrate box 141 can be selectively inserted into the first slot 311 or the second slot 312 at the top of the cross brace 31. When the concentrate box 141 is inserted into the first slot 311, the lower bend 10 fits against the side wall of the concentrate box 141 and no gap for material leakage is generated between the two. At the same time, the concentrate box 141 is prevented from swinging, so that the concentrate dripping through the concentrate end 101 can fall into the concentrate box 141 as much as possible, avoiding unnecessary loss of materials. When the concentrate box 141 is inserted into the second slot 312, driven by the bed plate 1, the concentrate box 141 can swing around the bottom end of the second slot 312, thereby shaking out the internal moisture.
