Description

Technical Field

[0001] The present invention relates to the technical field of ore dressing shaking tables, and particularly to ore dressing shaking tables, zircon sand production lines and processing methods. Background Art

[0002] After zircon sand raw ore is dried and dry magnetic separated, zircon sand raw ore is obtained. After the zircon sand raw ore is ground, zircon sand slurry is obtained. The zircon sand slurry needs to be sorted by a shaking table water separation to obtain concentrate and tailings; then, the concentrate needs to be dried, dry magnetic separated, electrostatic separated, high-intensity magnetic separated, etc. in sequence to refine zircon products and monazite.

[0003] After the shaking table water separation, the concentrate is in a slurry state and contains a large amount of water. Usually, it is necessary to precipitate, pump water, screen, and dry / bake in sequence for drying before it can be used for magnetic separation; such an operation form requires a large amount of time, resulting in a reduction in production efficiency. Summary of the Invention

[0004] In order to overcome the problem of "drying the concentrate slurry requires a large amount of time, resulting in a reduction in the overall production efficiency" existing in the above background art, the present invention provides an ore dressing shaking table, a zircon sand production line and a processing method.

[0005] The technical solutions adopted by the present invention to solve the above technical problems are as follows: An ore dressing shaking table, comprising a bed plate, a bottom support module and a side support module; a bed bar is provided on the upper surface of the bed plate; the bed plate is provided with a feeding end and a discharging end; a water feeding hopper and an ore feeding hopper are provided at the position of the feeding end; a receiving assembly is provided at the position of the discharging end, and the receiving assembly includes a concentrate box, a middlings box and a tailings box; the bottom support module is fixedly installed on the lower surface of the bed plate; the side support module includes a cross support arm for supporting the concentrate box, a first card slot is provided at the end of the cross support arm close to the bed plate, and a second card slot is provided at the end away from the bed plate; a water permeable structure is provided at the bottom of the concentrate box; the concentrate box can be selectively clamped into the first card slot or the second card slot; a downward bending part in a plate-like structure is provided at the concentrate end of the bed plate; the downward bending part can laterally abut against the concentrate box clamped into the first card slot to prevent it from swinging; the bed plate and the cross support arm can reciprocate horizontally to drive the concentrate box clamped into the second card slot to swing to drain the water in the concentrate.

[0006] As a further optimized solution 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 vertically and fixedly connected to the two end faces of the box body, the first rotating shaft can be selectively clamped into the first card slot or the second card slot, and the second rotating shaft can be selectively clamped into the first card slot or the second card slot.

[0007] As a further optimized solution of the present invention, the box body includes an abutting vertical plate, a counterweight arc plate and an end plate that are fixedly connected to each other; the abutting vertical plate can be adapted to and laterally abut against the downward bent portion; the counterweight arc plate is placed at the bottom end of the abutting vertical plate, and the middle of the abutting vertical plate is at the same height as the first rotating shaft.

[0008] As a further optimized solution of the present invention, the abutting vertical plate and the counterweight arc plate are connected in a U shape.

[0009] As a further optimized solution of the present invention, the counterweight arc plate is provided with water permeable holes.

[0010] As a further optimized solution of the present invention, the side support module further includes an inner support beam; the bottom support module and the downward bent portion are respectively arranged on both sides of the inner support beam, and the two side walls of the inner support beam are respectively adapted to and fixedly connected to the downward bent portion and the inner support beam; both ends of the inner support beam are outside the upper projection range of the bed plate, and the end of the cross support arm and the end of the inner support beam are fixedly connected by a plurality of diagonal braces.

[0011] As a further optimized solution of the present invention, the inner support beam has an arc-shaped structure with the middle convex upward, and one end of the diagonal brace close to the cross support arm is inclined upward and the end close to the inner support beam is inclined downward, so as to guide the middlings pulp dripping from the middlings end of the bed plate into the middlings box.

[0012] As a further optimized solution of the present invention, it further includes a lateral drive module for driving the bed plate to reciprocate horizontally.

[0013] A zircon sand production line includes a beneficiation shaking table, and also includes a grinding module and a drying module.

[0014] 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 ore dressing 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 transverse drive module, and the concentrate dripping from the concentrate end of the bed plate falls into the concentrate box a; S24, close the transverse 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 transverse 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 the drained concentrate.

[0015] In summary, the present invention has at least one of the following benefits: (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 synchronously drive the concentrate box to swing. The swinging of the bottom 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 water content 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.

[0016] (2) The cross brace arm is used to support the concentrate box, and the concentrate box can be selectively inserted into the first slot or the second slot on the top of the cross brace arm. 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 board and the cross brace arm, the concentrate box can swing around the bottom of the second slot as the center, thereby shaking out the internal moisture.

[0017] (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. The downtime is short, and a high production and processing efficiency is guaranteed.

[0018] (4) The inner support beam can support the downward-bent part from the inside, avoiding the problem that the concentrate box presses against the downward-bent part due to inertia, resulting in deformation of the downward-bent part, and further avoiding the problem of slurry leakage gap between the concentrate box and the downward-bent part. At the same time, the inner support beam can support the cross support arm.

[0019] (5) The inner support beam is in an arc-shaped structure with the middle convex upward, so as to prevent the middle slurry from flowing along the inner support beam to directly below the bed plate; several diagonal braces are connected between the end of the cross support arm and the end of the inner support beam. One end of the diagonal brace close to the cross support arm is inclined upward, and one end close to the inner support beam is inclined downward, preventing the middle slurry from flowing to the position of the cross support arm; finally, the middle slurry is diverted into the middle ore box to avoid material loss.

[0022] Based on the above structural characteristics of the present application, the implementation manners of the present application are further described as follows: Refer to Figures 1 to 3 , this embodiment provides a beneficiation shaking table, including a bed plate 1, a bottom support module 2 and a side support module 3. The bed plate 1 is used to support and separate zircon sand slurry; the bottom support module 2 is used to support the bed plate 1 and at the same time prevent the bed plate 1 from bending and deforming, ensuring the flatness of the bed plate 1. The side support module 3 is used to achieve the draining of the concentrate. After draining, the concentrate is directly dried, greatly reducing the time required for drying and improving the production and processing efficiency.

[0023] Refer to Figures 1 to 2 , the upper surface of the bed plate 1 is provided with bed bars 11; there are several bed bars 11 and they are arranged parallel to each other, and the bed bars 11 are arranged along the length direction of the bed plate 1. The space between adjacent bed bars 11 forms a feed trough for separation, and zircon sand particles with different particle sizes / densities are stratified in the feed trough. The separation of zircon sand particles by the impact of water flow during the process of traveling along the feed trough is all conventional existing technologies in the industry and will not be elaborated here.

[0024] Refer to Figures 1 to 2, at the edge positions of the bedplate 1, there are a feeding end and a discharging end. The height of the side where the feeding end is located is slightly higher than that of the side where the discharging end is located (i.e., the bedplate 1 is inclined, and the inclination angle is usually 2 degrees to 8 degrees), so as to enable the zircon sand mortar to flow from the feeding end to the discharging end. At the feeding end position, there are a water feeding hopper 12 and an ore feeding hopper 13. The water feeding hopper 12 is fixedly connected to the upper surface of the bedplate 1 (for example, by welding or by bolt connection), and the ore feeding hopper 13 is fixedly connected to the upper surface of the bedplate 1 (for example, by welding or by bolt connection). On one side of the water feeding hopper 12 away from the ore feeding hopper 13, there is a diversion groove 121, and the diversion groove 121 is fixedly connected to the upper surface of the bedplate 1 (for example, by welding or by bolt connection); the diversion groove 121 is communicated with the water feeding hopper 12, and strip-shaped water outlet holes are arranged at the bottom of the diversion groove 121, so as to discharge a flat water flow. A dilution tank 131 is arranged between the water feeding hopper 12 and the ore feeding hopper 13, and the dilution tank 131 is fixedly connected to the upper surface of the bedplate 1 (for example, by welding or by bolt connection); the dilution tank 131 is communicated with the ore feeding hopper 13, and strip-shaped pulp outlet holes are arranged at the bottom of the dilution tank 131, so as to discharge a flat pulp flow.

[0025] Refer to Figures 1 to 2 , the discharging end includes a concentrate end 101, a middling end 102 and a tailings end 103, which are respectively used for discharging concentrate, middling and tailings; 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 bedplate 1, the middling and tailings are arranged on the long side of the bedplate 1, and the middling is arranged between the concentrate and the tailings; all are conventional existing technologies in the industry and will not be elaborated here.

[0026] Refer to Figures 1 to 2 , at the discharging end position, there is a material receiving assembly 14, 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 respectively match 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.

[0027] Refer to Figures 3 to 5, the bottom support module 2 is fixedly installed 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 several first support beams 21 arranged in parallel with each other, and there are several second support beams 22 arranged in parallel with each other. The first support beam 21 and the second support beam 22 are arranged perpendicular to each other and form a grid-like support structure, thereby realizing the support for the bed board 1. The bed board 1 is in a planar shape; the first support beam 21 is arranged along the short side direction of the bed board 1, and the second support beam 22 is arranged along the long side direction of the bed board 1; the top surface of the first support beam 21 is in close contact with and fixedly connected to the bottom surface of the bed board 1 (for example, fixedly connected by bolts or fixedly connected by welding), and the bottom surface of the first support beam 21 is in close contact with and fixedly connected to the top surface of the second support beam 22 (for example, fixedly connected by bolts or fixedly connected by welding). Both the first support beam 21 and the second support beam 22 are straight square tube structures.

[0028] Referring to Figures 3 to 5 , the side support module 3 includes a cross support arm 31 for supporting the concentrate box 141. There are two cross support arms 31 arranged in parallel with each other, and the two cross support arms 31 are respectively arranged on both sides of the bed board 1; the cross support arm 31 is arranged parallel to the bed board 1; one end of the cross support arm 31 is close to the bed board 1 and the other end is far from the bed board 1. The cross support arm 31 is arranged along the length direction of the bed board 1; the end of the cross support arm 31 is connected to the end of the bed board 1.

[0029] Referring to Figures 3 to 5 , a first card slot 311 is provided at the end of the top of the cross support arm 31 close to the bed board 1, and a second card slot 312 is provided at the end far from the bed board 1. The first card slots 311 on the two cross support arms 31 are arranged in a matching manner; the second card slots 312 on the two cross support arms 31 are arranged in a matching manner; when the two ends of the concentrate box 141 are respectively inserted into the two first card 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 inserted into the two second card slots 312, the length direction of the concentrate box 141 is parallel to the width direction of the bed board 1.

[0030] Referring to Figures 3 to 5 , the concentrate box 141 can be selectively inserted into the first card slot 311 or the second card slot 312. When the concentrate box 141 is inserted into the first card slot 311, it cannot swing, so as to stably receive the dropped concentrate. When the concentrate box 141 is inserted into the second card slot 312, it can swing reciprocally along with the reciprocal lateral movement of the bed board 1, thereby throwing out the water adhered to the concentrate inside the concentrate box 141.

[0031] Referring to Figures 3 to 5The end of the bed plate 1 where the concentrate end 101 is located is provided with a lower bent portion 10 of a plate-like structure, and the lower bent portion 10 and the bed plate 1 are arranged perpendicular to each other. The lower bent portion 10 is a vertical strip-like structure. The lower bent portion 10 can laterally abut against the concentrate box 141 inserted into the first slot 311 to prevent it from swinging. The bed plate 1 and the cross brace arm 31 can synchronously reciprocate and move horizontally to drive the concentrate box 141 inserted into the second slot 312 to swing, so as to drain the moisture in the concentrate in the inner cavity of the concentrate box 141.

[0032] 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 respectively vertically fixedly connected to the two end surfaces of the box body 1411. The first rotating shaft 1412 can be selectively inserted into the first slot 311 or the second slot 312, and the second rotating shaft 1413 can be selectively inserted into the first slot 311 or the second slot 312. The first rotating shaft 1412 and the second rotating shaft 1413 can be respectively inserted into the first slot 311 of the two cross bracing arms 31, or respectively inserted into the second slot 312 of the two cross bracing arms 31.

[0033] Reference Figure 6 and Figure 7 The box body 1411 includes abutting upright plate 14111, a weighted arc plate 14112 and an end plate 14113 which are fixedly connected to each other; the abutting upright plate 14111 can fit and abut with the lower curved portion 10 in a horizontal manner, thereby preventing the box body 1411 from swinging and preventing a gap between the two from leaking. The weighted 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, so that the bottom weight of the concentrate box 141 is greater than the top weight, so that the concentrate box 141 swings under the push of the bed plate 1 instead of rotating in a 360-degree circle, so as to prevent the concentrate in the inner cavity of the concentrate box 141 from falling out.

[0034] 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 portion. The abutting vertical plate 14111 is in the shape of a straight plate, and two abutting vertical plates 14111 are provided and arranged parallel to each other; the bottom ends of the two abutting vertical plates 14111 are tangent to the two ends of the counterweight arc plate 14112 respectively and fixedly connected (for example, fixedly connected by welding or fixedly connected by an integrated type). 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 end of the top surface of the counterweight arc plate 14112 (for example, fixedly connected by bolts or fixedly connected by welding).

[0035] A water-permeable structure is provided at the bottom of the concentrate box 141. The water-permeable structure is, for example, a water-permeable hole or a filter cotton layer. The water-permeable holes are provided on the counterweight arc plate 14112. The counterweight arc plate 14112 includes an edge frame and a metal mesh. The edge frame is arranged at the outer edge position of the metal mesh and fixedly connected (for example, fixed by welding or fixed by a bar and bolts). The water-permeable holes are provided between the metal wires of the metal mesh. The water mixed in the concentrate in the inner cavity of the concentrate box 141 is drained out through the water-permeable holes.

[0036] Refer to Figures 3 to 6 , the side support module 3 further includes an inner support beam 32; the bottom support module 2 and the lower bending part 10 are respectively arranged on both sides of the inner support beam 32. The two side walls of the inner support beam 32 are respectively adapted to and fixedly connected with the lower bending part 10. The inner support beam 32 is fixedly connected with the side wall of the lower bending part 10 by welding or by fasteners and bolts. The inner support beam 32 is fixedly connected with the end face of the second support beam 22 (for example, fixedly connected by welding or by bolts), so as to fix the inner support beam 32. The inner support beam 32 is used to apply a lateral supporting force to the lower bending part 10 to prevent the lower bending part 10 from bending inward (that is, in the direction of the bottom support module 2). During the reciprocating transverse movement of the bedplate 1, under the action of inertia, the concentrate box 141 stuck in the first card slot 311 will repeatedly transversely press against the lower bending part 10, making the lower bending part 10 tend to bend inward), further preventing a slurry leakage gap from appearing between the concentrate box 141 and the lower bending part 10 (after the lower bending part 10 bends inward, the lower bending part 10 no longer fits with the abutting vertical plate 14111, thus a slurry leakage gap appears), and further preventing the problem that the concentrate flows out through the slurry leakage gap instead of entering the concentrate box 141.

[0037] Refer to Figure 3 , both ends of the inner support beam 32 are outside the upper projection range of the bedplate 1, that is, both ends of the inner support beam 32 extend out from directly below the bedplate 1, so as to be used for connecting with the cross support arms 31. The two cross support arms 31 are respectively vertically and fixedly connected with both ends of the inner support beam 32. The inner support beam 32 plays a structural support function for the cross support arms 31.

[0038] Refer to Figure 3 And Figure 8 , the end of the cross support arm 31 is fixedly connected with the end of the inner support beam 32 by a plurality of diagonal support rods 313. A triangular support structure is formed between adjacent diagonal support rods 313, so as to improve the connection force between the cross support arm 31 and the inner support beam 32 and improve the structural stability.

[0039] Refer to Figure 3 , Figure 8 And Figure 9, the inner support beam 32 has an arc-shaped structure with the middle part convex upward. One end of the diagonal brace 313 close to the cross brace 31 is inclined upward, and one end close to the inner support beam 32 is inclined downward, so as to divert the middlings pulp dripping from the middlings end 102 of the bed plate 1 into the middlings box 142. The middlings box 142 is located below the end of the inner support beam 32 close to the discharge end.

[0040] Refer to Figure 9 , the inner support beam 32 has an arc-shaped structure with the middle part convex upward, so the upper surface of the end of the inner support beam 32 is inclined, so that the middlings (i.e., the middlings pulp, in a slurry state) dripping from the middlings end 102 fall on the upper surface of the end of the inner support beam 32, and then further drip into the middlings box 142, preventing the middlings pulp from flowing along the upper surface of the inner support beam 32 to directly below the bed plate 1. If the middlings pulp flows to directly below the bed plate 1 (such as the middle part of the inner support beam 32), it will drip on the ground of the processing workshop, causing unnecessary loss of materials.

[0041] Refer to Figure 8 , since the side where the discharge end of the bed plate 1 is located is inclined downward, and one end of the cross brace 31 close to the bed plate 1 is inclined upward, the diagonal brace 313 is used to prevent the middlings pulp adhering to the surface of the inner support beam 32 from flowing in the direction of the cross brace 31. If the middlings pulp flows obliquely downward along the length direction of the cross brace 31, it will finally drip at the end of the cross brace 31 far 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 materials. In the present invention, one end of the diagonal brace 313 close to the cross brace 31 is inclined upward, and one end close to the inner support beam 32 is inclined downward, so that the middlings pulp cannot flow upward from the bottom end of the diagonal brace 313 to the top end of the diagonal brace 313, and thus cannot contact the cross brace 31.

[0042] Refer to Figure 2 And Figure 10 , the middlings box 142 is arranged below the middlings end 102, and the tailings box 143 is arranged below the tailings box 143; the concentrate box 141, the middlings box 142, and the tailings box 143 are all box structures with openings at the top. A cover plate that can be opened and closed is provided at the opening position at the top of the concentrate box 141, and the edge position of the cover plate is detachably connected to the top surface of the end plate 14113 (for example, through a spring buckle, an elastic buckle, or by bolts for detachable connection). When it is necessary to swing the concentrate box 141 for water drainage, the cover plate is installed at the opening position at the top of the concentrate box 141 in advance, so as to prevent the fine ore particles inside the concentrate box 141 from accidentally splashing out when the concentrate box 141 swings.

[0043] Refer to Figure 2 And Figure 10, a waste slurry tank 15 is arranged below the material receiving assembly 14. The waste slurry tank 15 has an L-shaped structure to fit the concentrator box 141, middlings box 142, and tailings box 143 arranged in an L shape; the concentrator box 141 is suspended above the waste slurry tank 15 through a cross brace 31; the middlings box 142 and the tailings box 143 are pressed against the top surface of the side plate of the waste slurry tank 15 and fixedly connected (for example, fixedly connected by bolts or fixedly connected by welding); the waste slurry tank 15 is used to receive the waste slurry flowing out from the non-discharge end position of the edge of the bed plate 1.

[0044] Refer to Figure 3 With Figure 10 , the width L of the part of the waste slurry tank 15 located below the concentrator box 141 is adapted to the length of the cross brace 31, so that the concentrator box 141 can be located within the range directly above the concentrator box 141 whether it is clamped into the first card slot 311 or the second card slot 312; and, when the concentrator box 141 swings in the second card slot 312, the water thrown out can drip into the waste slurry tank 15. The waste slurry tank 15 is placed on the ground of the processing workshop.

[0045] Refer to Figure 11 , a reinforcing rod 314 is connected to the bottom end of the inner support beam 32. The reinforcing rod 314 is inclined. One end of the reinforcing rod 314 close to the cross brace 31 is inclined upward and one end close to the inner support beam 32 is inclined downward; the reinforcing rod 314 is in a straight rod shape. One end of the reinforcing rod 314 is fixedly connected to the bottom of the inner support beam 32 (for example, fixedly connected by bolts or fixedly connected by welding), and the other end is fixedly connected to the middle of the outer side wall of the cross brace 31 (for example, fixedly connected by bolts or fixedly connected by welding), thus forming a triangular support structure to enhance the bearing capacity of the cross brace 31 and prevent the connection positions of the cross brace 31, inner support beam 32, and diagonal brace 313 from being overloaded and disconnected and failing.

[0046] Refer to Figure 1 , a water baffle 16 is provided at the end of the bed plate 1 away from the discharge end. The water baffle 16 is connected to the outer side wall of the ore feeding hopper 13 (for example, fixedly connected by bolts or fixedly connected by welding). The water baffle 16 stands on the upper surface of the bed plate 1 and is fixedly connected to the bed plate 1 (stereoscopically fixedly connected by welding or fixedly connected by bolts). The water baffle 16 is used to prevent the zircon sand mortar from accidentally flowing out from the end of the bed plate 1 away from the discharge end.

[0047] Refer to Figure 6, a limit sleeve 1414 is sleeved and fixed on the surface of the second rotating shaft 1413 (for example, fixed and connected by bolts); the distance between the two end faces of the limit sleeve 1414 away from the box body 1411 is adapted to the distance between the two cross braces 31. That is, when the concentrate box 141 is snapped into the first card slot 311 or the second card slot 312, the end face of the limit sleeve 1414 away from the box body 1411 is in contact with the side wall of one of the cross braces 31, and the end face of the box body 1411 away from the limit sleeve 1414 is in contact with the side wall of the other cross brace 31, so as to limit the box body 1411 at a position close to the concentrate end 101, prevent the box body 1411 from sliding along the width direction of the bed plate 1, further improve the hit rate of receiving materials (receiving concentrate), and at the same time prevent the first rotating shaft 1412 from disengaging from the first card slot 311 / second card slot 312.

[0048] The ore dressing shaking table further includes a lateral driving module for driving the bed plate 1 to reciprocate horizontally 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 guiding structure (such as a slide rail structure) or a rolling guiding structure for the relative movement of the bottom support module 2 and the bed frame; the fixed seat of the lateral driving module is fixedly connected to the processing workshop floor or the bed frame (for example, fixed and connected 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, fixed and connected by bolts), and the lateral driving module can drive the bottom support module 2 and the bed plate 1 to move horizontally synchronously. The lateral driving module adopts, for example, a cam lever headstock, an eccentric connecting rod headstock or a spring headstock, etc., which are all conventional existing technologies in the industry and will not be elaborated here.

[0049] The slide rail structure includes a slider and a slide rail. The cross section of the slider is C-shaped, and the cross section of the slide rail is gourd-shaped. The slider is buckled on the slide rail to prevent falling off; the slider can reciprocate along the length direction of the slide rail. The slider is fixedly connected to the bottom support module 2 by bolts, and the slide rail is fixedly connected to the bed frame by bolts. The length direction of the slide rail is parallel to the length direction of the bed plate 1; the lateral driving module can drive the bed plate 1 to reciprocate horizontally along the length direction of the slide rail.

[0050] The rolling guiding structure includes a track and a roller. The vertical cross section of the track is an equilateral triangle, and the circumferential surface of the roller is provided with an annular groove. The track is fixedly installed on the bed frame by bolts, and the roller is rotatably installed on the bottom surface of the bottom support module 2 through a bearing and a bearing seat. The roller is pressed against the track and the top tip of the track is inserted into the annular groove; the roller can roll along the length direction of the track. The length direction of the track is parallel to the length direction of the bed plate 1; the lateral driving module can drive the bed plate 1 to reciprocate horizontally along the length direction of the track.

[0051] The zircon sand production line includes a beneficiation shaking table, and also includes a grinding module and a drying module. The grinding module uses equipment such as ball mills, rod mills, pebble mills, autogenous mills, vibration mills, etc., which are all conventional existing technologies in the industry and will not be elaborated here. The drying module, such as a drying chamber, is a conventional existing technology in the industry and will not be elaborated here.

[0052] The zircon sand processing method, that is, the steps of processing zircon sand using the zircon sand production line include: S1. Use the grinding module to grind the raw zircon sand to obtain zircon sand slurry (water is added during or after the grinding process to form a slurry).

[0053] S2. Use the beneficiation shaking table to separate the zircon sand slurry to obtain concentrate, and drain the concentrate to obtain drained concentrate.

[0054] S3. Dry the drained concentrate to obtain dried concentrate.

[0055] Step S2 further includes the following steps: S21. Take an empty concentrate box 141 and define it as concentrate box a141a, and snap the concentrate box a141a into the first card slot 311.

[0056] S22. Inject clear water and zircon sand slurry into the water supply hopper 12 and the ore supply hopper 13 respectively.

[0057] S23. Start the lateral drive module, and the concentrate dripping from the concentrate end 101 of the bed plate 1 falls into the concentrate box a141a.

[0058] S24. When a certain amount of concentrate is collected in the concentrate box a141a, turn off the lateral drive module, take out the concentrate box a141a from the first card slot 311 and snap it into the second card slot 312; take another empty concentrate box 141 and define it as concentrate box b141b, and snap the concentrate box b141b into the first card slot 311 (refer to Figure 3 )

[0059] S25. Start the lateral drive module; the concentrate dripping from the concentrate end 101 of the bed plate 1 falls into the concentrate box b141b; during the reciprocating lateral movement of the bed plate 1 and the cross brace 31, the concentrate box a141a is driven to swing, and the water inside the concentrate box a141a is drained during the swinging process to obtain drained concentrate (refer to Figure 3 )

[0060] The structure of the present invention is simple and the function is reliable. During the process of the reciprocating lateral movement of the bed plate 1 to separate the concentrate, the concentrate box 141 can be synchronously driven to swing, and the swinging of the bottom end of the concentrate box 141 can throw out the water adhered to the concentrate in the inner cavity, so as to realize the rapid drainage of the concentrate. The drained concentrate can be directly dried in the sun or dried, without the need for the precipitation, pumping, and sieving operations in the traditional technology, which can simplify the operation steps and improve the efficiency of the processing operation.

[0061] The cross brace 31 is used to support the concentrate box 141, and the concentrate box 141 can be selectively clamped into the first clamping groove 311 or the second clamping groove 312 at the top of the cross brace 31. When the concentrate box 141 is clamped into the first clamping groove 311, the downward bending part 10 is attached to the side wall of the concentrate box 141 and there will be no leakage gap between the two, and at the same time, the swing of the concentrate box 141 is avoided. Then, the concentrate dripping from 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 clamped into the second clamping groove 312, driven by the bed plate 1, the concentrate box 141 can swing around the bottom end of the second clamping groove 312, so as to throw out the internal moisture.
