Description

Technical Field

[0001] The invention relates to the technical field of flotation equipment, and in particular to an industrial lithium carbonate coarse material eluting device. Background Art

[0002] Lithium carbonate is the raw material for the positive electrode of lithium batteries and is widely used in the fields of mobile power, electric vehicles, etc. Crude lithium carbonate refers to lithium carbonate extracted from lithium ore or salt lake brine, which has undergone preliminary processing but has not yet reached industrial grade or battery grade standards in purity. It usually contains a certain amount of impurities, which need to be removed and improved in purity by elution to meet the needs of different application fields. Flotation is an important part of the elution process. The specific method is to use foam flotation technology to react the crude lithium carbonate slurry with CO2 gas to generate lithium bicarbonate solution, and then add anionic surfactants, form foam by introducing air, and use the flotation properties of the foam to remove impurity metal ions, thereby improving the purity of lithium carbonate.

[0003] A Chinese patent document with authorization announcement number CN118179762B discloses a molybdenum concentrate raw material purification and processing device, in which a foam pushing plate continuously pushes froth out of a flotation cell chamber through the cooperation of a first control block and a second control block. This structure allows the foam pushing plate to cover the top opening of the flotation cell chamber within its moving range, so that it can quickly and efficiently push out the froth on the top layer of the slurry without waiting for the top layer of the slurry to flow to the froth outlet end of the flotation cell chamber, thereby improving the flotation purification efficiency of the device for the slurry.

[0004] However, when the above-mentioned molybdenum concentrate raw material purification and processing device in the prior art produces abundant froth on the top layer of the slurry, the froth pushing plate pushes the froth on the top layer of the slurry from one end to the other end of the flotation cell chamber. During the pushing process of the froth pushing plate, the froth located near the slot may stay in the flotation cell chamber for too long, and the flow of froth may also cause the foam to burst. These situations will affect the stability of the foam, thereby causing the target mineral particles in the froth layer to sink back into the slurry, thereby reducing the sorting efficiency. Summary of the invention

[0005] The present invention provides an industrial lithium carbonate crude material eluting device, aiming to solve the problem that the foam pushing process of the foam pushing plate in the molybdenum concentrate raw material purification and processing device in the related art is easy to affect the stability of the foam, causing the target mineral particles in the froth layer to sink back into the ore pulp, thereby reducing the sorting efficiency.

[0006] The invention provides an industrial lithium carbonate crude material elution device adopts the following technical scheme:

[0007] An industrial lithium carbonate crude material stripping device comprises a flotation tank, the flotation tank has a notch for discharging froth, and also comprises: a froth support member, the froth support member is arranged in the flotation tank, the froth support member comprises a plurality of flexible lifting strips arranged in sequence along the width direction of the notch, the flexible lifting strips are used to lift the froth layer upward to separate the froth layer from the ore pulp; a reel and a retractable motor, the reel is rotatably installed at the notch, one end of the froth support member close to the notch is wound on the reel, the retractable motor is installed outside the flotation tank and drives the reel to rotate to reel in or unreel the froth support member; a guide rail and a traction rod, the guide rail is arranged It is arranged on the inner wall of the flotation tank, the traction rod is movably installed in the guide rail, the end of the foam supporting member away from the slot is arranged on the traction rod to move along the guide rail with the traction rod, the guide rail includes a first circuit for guiding the foam supporting member to enter the ore pulp, a second circuit for guiding the foam supporting member to move upward from the ore pulp to lift the froth layer, and a third circuit for guiding the foam supporting member to drive the froth layer to move toward the slot; a turning device is arranged on the traction rod to drive each flexible lifting strip to turn over to a vertical state in the ore pulp, so that the foam can float upward from between two adjacent flexible lifting strips.

[0008] By adopting the above technical scheme, a foaming member including a plurality of flexible lifting strips, a reel for winding the foaming member, a traction rod for pulling the traction end of the foaming member to move along the guide rail, and a turning device for driving each flexible lifting strip to turn over is arranged in the flotation tank; the traction end of the foaming member is driven by the traction rod to move along the first circuit into the ore pulp, and at the same time, the turning device drives each flexible lifting strip to turn over to a vertical state in the ore pulp, so that during the process of foam generation and flotation, the foam can float upward from between two adjacent flexible lifting strips without affecting the formation of the froth layer; the traction end of the foaming member is driven by the traction rod to move along the second circuit so that the foaming member moves up from the ore pulp, and at the same time, the turning device drives each flexible lifting strip to recover to a horizontal state, so that each flexible lifting bar can directly lift up the froth layer, so that the froth layer is separated from the ore pulp; the traction end of the froth supporting member is driven by the traction rod to move along the third loop so that the froth supporting member drives the froth layer to move toward the slot, so as to collect the froth layer; thus, by arranging the flippable flexible lifting bar, the flexible lifting bar can directly lift up the froth layer directly below the froth layer, thereby reducing the flow of the froth layer during the froth collection process, thereby reducing the froth destruction caused by friction or collision, and preventing the froth from staying in the flotation tank for too long, which helps to maintain the uniformity and stability of the froth layer, and avoids the target mineral particles in the froth layer from sinking back into the ore pulp as much as possible, thereby effectively improving the sorting efficiency.

[0009] Furthermore, the flipping device includes a rack assembled in the traction rod and movable along the width direction of the slot, a spring connected between the rack and the traction rod, a gear arranged at the end of each flexible lifting bar away from the slot and meshing with the rack, an abutment head is arranged at the end of the rack close to the guide rail, and a limit block capable of pushing the abutment head is arranged on the inner wall of the flotation tank.

[0010] By adopting the above technical solution, the flipping device controls the flexible lifting bar to flip and switch between vertical and horizontal states through the engagement of the gear and the rack. The gear and rack mechanism can provide precise motion control to ensure the accuracy and stability of the flipping of the flexible lifting bar.

[0011] Furthermore, the first loop includes an inclined loop that slopes downward from the slot into the flotation tank, and a horizontal loop that extends horizontally from the slot in the flotation tank toward a direction away from the slot. The limit block extends along the horizontal loop and the second loop, and inclined surfaces are respectively provided at the starting end of the horizontal loop and the end end of the second loop.

[0012] Furthermore, an end rod extending along the width direction of the slot is fixed to one end of each of the flexible lifting strips away from the slot, and the gear located in the traction rod is installed at one end of the end rod.

[0013] By adopting the above technical solution, the end rods are used to maintain the neatness and uniformity of the flexible lifting strips, so as to facilitate the turning of the flexible lifting strips.

[0014] Furthermore, the inner wall of the flotation tank is fixed with retaining rods corresponding to and arranged in pairs with each flexible lifting bar. The retaining rods are located at one end of the flotation tank close to the slot and are used to limit each flexible lifting bar after the flipping device drives each flexible lifting bar to flip to a vertical state, so that the flexible lifting bar remains in a vertical state.

[0015] By adopting the above technical solution, the flexible lifting strip between the traction rod and the retaining rod can be kept in a vertical state, thereby ensuring that the foam generated in the flotation tank can float upward through between two adjacent flexible lifting strips without affecting the formation of the froth layer.

[0016] Furthermore, the industrial lithium carbonate coarse material elution device also includes a limit rod installed in the flotation tank and moved along the width direction of the slot, and a linear driving component installed outside the flotation tank and driving the limit rod to move. The limit rod is located at one end of the flotation tank close to the slot. When the linear driving component drives the limit rod to extend into the flotation tank, the limit rod can limit the position of the foam supporting part to guide the foam supporting part to move around the limit rod in the slurry.

[0017] Furthermore, the foam supporting member also includes a frame arranged on the upper surface of each flexible lifting strip, and the frame includes a transverse frame extending along the width direction of the slot and a longitudinal frame connected between multiple transverse frames. When the limiting rod extends into the flotation tank, it can abut against the frame to limit the position of the foam supporting member.

[0018] By adopting the above technical solution, when the frame is acted upon by the limiting rod, the transverse frame in the frame can limit the upward movement of each flexible lifting strip, thereby limiting the position of each flexible lifting strip, so that each flexible lifting strip is located in the slurry to avoid contact with the froth layer.

[0019] Furthermore, the industrial lithium carbonate crude material elution device also includes a traction device for driving the traction rod to move, the traction device includes a chain installed in the guide rail, a driving wheel driving the chain to move, a guide wheel supporting and guiding the chain to move along the guide rail, and a traction motor installed outside the flotation tank to drive the driving wheel to rotate, and the traction rod is arranged on the chain to move with the chain.

[0020] Furthermore, the flotation tank is provided with a plurality of flushing nozzles arranged in sequence along the width direction of the slot at the slot opening, and the flushing nozzles face the foam supporting member to flush the foam layer raised by the foam supporting member.

[0021] Furthermore, the industrial lithium carbonate crude material elution device also includes a collecting tank arranged outside the flotation tank and below the flushing nozzle, and the collecting tank is used to collect the froth layer flushed by the flushing nozzle.

[0022] The beneficial effects of the industrial lithium carbonate coarse material washing device provided by the present invention are as follows: a foaming member including a plurality of flexible lifting strips, a reel for winding the foaming member, a traction rod for pulling the traction end of the foaming member to move along a guide rail, and a turning device for driving each flexible lifting strip to turn over are arranged in the flotation tank; the traction end of the foaming member is driven by the traction rod to move along the first circuit into the ore pulp, and at the same time, the turning device drives each flexible lifting strip to turn over to a vertical state in the ore pulp, so that during the process of foam generation and flotation, the foam can float upward from between two adjacent flexible lifting strips without affecting the formation of a froth layer; the traction end of the foaming member is driven by the traction rod to move along the second circuit so that the foaming member moves upward from the ore pulp, and at the same time, the turning device drives Each flexible lifting bar is restored to a horizontal state so that each flexible lifting bar can directly lift up the froth layer to separate the froth layer from the ore pulp; the traction end of the froth supporting member is driven by the traction rod to move along the third loop so that the froth supporting member drives the froth layer to move toward the slot to facilitate the collection of the froth layer; thus, by arranging a flippable flexible lifting bar, the flexible lifting bar can directly lift up the froth layer directly below the froth layer, reducing the flow of the froth layer during the froth collection process, thereby reducing the froth destruction caused by friction or collision, and preventing the froth from staying in the flotation tank for too long, which helps to maintain the uniformity and stability of the froth layer, and avoids the target mineral particles in the froth layer from sinking back into the ore pulp as much as possible, thereby effectively improving the sorting efficiency.

DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 5 As shown, an embodiment of the industrial lithium carbonate crude material elution device of the present invention includes a flotation tank 10, a limit block 120, a retaining rod 130, a flushing nozzle 140, a foam support 20, a reel 30, a retractable motor 310, a guide rail 40, a traction rod 50, a traction device, a turning device, a limit rod 80, a linear drive member 810 and a collecting tank 90.

[0032] like Figure 1 As shown, the flotation cell 10 is used to contain crude lithium carbonate slurry and perform a flotation process. The flotation cell 10 has a notch 110 for discharging froth.

[0033] like Figure 1 As shown, the foam support 20 is arranged in the flotation tank 10. The foam support 20 includes a plurality of flexible lifting strips 220 arranged in sequence along the width direction of the slot 110, and a frame 210 arranged on the upper surface of each flexible lifting strip 220. The flexible lifting strip 220 is made of cloth and is used to lift the froth layer upward to separate the froth layer from the ore pulp. The frame 210 is made of metal and includes a transverse frame 211 extending along the width direction of the slot 110 and a longitudinal frame 212 connected between the plurality of transverse frames 211. The transverse frame 211 made of metal can limit the upward movement of each flexible lifting strip 220 to limit the position of each flexible lifting strip 220.

[0034] like Figure 1 As shown, the reel 30 is rotatably mounted at the notch 110. One end of the foam support member 20 near the notch 110 is wound on the reel 30, and the retracting and unreeling motor 310 is mounted outside the flotation tank 10 and drives the reel 30 to rotate, so as to reel or unreel the foam support member 20.

[0035] like Figure 1 and Figure 2 As shown, the guide rail 40 is arranged on the inner wall of the flotation tank 10, the traction rod 50 is movably installed in the guide rail 40, and the end of the foam support member 20 away from the slot 110 is arranged on the traction rod 50 to move along the guide rail 40 with the traction rod 50. Specifically, the end of the frame 210 away from the slot 110 is fixed on the traction rod 50, and the end of each flexible lifting strip 220 away from the slot 110 is rotatably installed on the traction rod 50. The guide rail 40 includes a first circuit 410 for guiding the foam support member 20 to enter the ore pulp, a second circuit 420 for guiding the foam support member 20 to move upward from the ore pulp to lift the froth layer upward, and a third circuit 430 for guiding the foam support member 20 to drive the froth layer to move toward the slot 110. The first circuit 410 includes an inclined circuit 411 that is inclined downward from the slot 110 to the flotation tank 10, and a horizontal circuit 412 that extends horizontally from the slot 110 to the direction away from the slot 110 in the flotation tank 10.

[0036] like Figures 1 to 3 As shown, the traction device is used to drive the traction rod 50 to move. The traction device includes a chain 620 installed in the guide rail 40, a driving wheel 630 driving the chain 620 to move, a guide wheel 640 supporting and guiding the chain 620 to move along the guide rail 40, and a traction motor 610 installed outside the flotation tank 10 to drive the driving wheel 630 to rotate. The traction rod 50 is arranged on the chain 620 to move with the chain 620. When the traction motor 610 drives the driving wheel 630 to rotate, the driving wheel 630 drives the chain 620 to move by meshing with the chain 620. Since the guide wheel 640 and the driving wheel 630 support and guide the chain 620 to move along the guide rail 40, the chain 620 can drive the traction rod 50 to move in the guide rail 40.

[0037] like Figures 1 to 5 As shown, the flipping device is arranged on the traction rod 50 to drive each flexible lifting bar 220 to flip to a vertical state in the slurry, so that the foam can float upward from between two adjacent flexible lifting bars 220. The flipping device includes a rack 710 that moves and is assembled in the traction rod 50 along the width direction of the slot 110, a spring 730 connected between the rack 710 and the traction rod 50, and a gear 720 that is arranged at one end of each flexible lifting bar 220 away from the slot 110 and meshes with the rack 710. An end rod 221 extending along the width direction of the slot 110 is fixed to one end of each flexible lifting bar 220 away from the slot 110. The material of the end rod 221 is hard plastic to maintain the neatness and uniformity of the flexible lifting bar 220, so as to facilitate the flipping of the flexible lifting bar 220. One end of the end rod 221 is installed with a gear 720 located in the traction rod 50. An end of the rack 710 close to the guide rail 40 is provided with a contact head 711.

[0038] like Figure 2 and Figure 3 As shown, the limit block 120 is fixed to the inner wall of the flotation tank 10 on the side of the guide rail 40, and is used to push the abutment head 711. The limit block 120 extends along the horizontal loop 412 and the second loop 420, and is provided with inclined surfaces at the starting end of the horizontal loop 412 and the end end of the second loop 420 respectively.

[0039] like Figure 1 and Figure 2 As shown, the retaining rods 130 are fixed to the inner wall of the flotation tank 10 near one end of the notch 110, and the retaining rods 130 are arranged in pairs and correspond to each flexible lifting bar 220. There is a gap between the two pairs of retaining rods 130 to accommodate the flexible lifting bar 220, which is used to limit each flexible lifting bar 220 after the flipping device drives each flexible lifting bar 220 to flip to a vertical state, so that the flexible lifting bar 220 remains in a vertical state.

[0040] like Figure 1 and Figure 2 As shown, the limit rod 80 is installed in the flotation tank 10 to move along the width direction of the slot 110 and is located at the intersection of the inclined circuit 411 and the horizontal circuit 412. The linear drive 810 is installed outside the flotation tank 10 and drives the limit rod 80 to move. The linear drive 810 is an electric push rod, and the linear drive 810 can also be a hydraulic cylinder or a pneumatic cylinder. When the linear drive 810 drives the limit rod 80 to extend into the flotation tank 10, the limit rod 80 can abut against the frame 210 to limit the position of the foam support 20, thereby guiding the foam support 20 to move around the limit rod 80 in the slurry.

[0041] like Figure 1 and Figure 2 As shown, the water pipe 910 is arranged at the slot 110 of the flotation tank 10 and extends along the width direction of the slot 110. A plurality of flushing nozzles 140 are arranged on the water pipe 910 and are evenly arranged along the width direction of the slot 110. Each flushing nozzle 140 faces the foam supporting member 20 and is used to flush the foam layer raised by the foam supporting member 20.

[0042] like Figure 1 and Figure 2 As shown, the collecting tank 90 is arranged outside the flotation tank 10 and below the flushing nozzle 140 . The collecting tank 90 is used to collect the froth layer flushed by the flushing nozzle 140 .

[0043] The working process of the embodiment of the industrial lithium carbonate crude material stripping device provided by the present invention comprises the following steps:

[0044] The first step is to adjust the slurry, react the crude lithium carbonate slurry with CO2 gas to generate a lithium bicarbonate solution, and then add anionic surfactant; at the same time, the traction device drives the traction rod 50 to move along the first loop 410, the retracting and discharging motor 310 drives the reel 30 to rotate to unwind the foam support member 20, and the traction rod 50 drives the traction end of the foam support member 20 to enter the ore pulp in the flotation tank 10 along the inclined loop 411, and the linear drive member 810 drives the limit rod 80 to extend into the flotation tank 10, so that when the traction rod 50 drives the traction end of the foam support member 20 from the inclined loop 411 to enter the horizontal loop 412, the foam support member 20 can move around the limit rod 80 in the ore pulp, that is, when the traction rod 50 moves along the horizontal loop 412, the foam support member 20 is located in the ore pulp to avoid contact with the froth layer; after the traction rod 50 drives the traction end of the foam support member 20 to enter the horizontal loop 412, the contact head 7 11 moves along the inclined surface of the limit block 120, and the contact head 711 is pushed by the limit block 120 to drive the rack 710 to squeeze the spring 730 to move. The spring 730 stores elastic potential energy, and the rack 710 engages with the gear 720 to drive the traction end of the flexible lifting bar 220 to flip downward to a vertical state. After flipping to the vertical state, the flexible lifting bar 220 enters the paired retaining rods 130 to maintain the vertical state; until the traction rod 50 drives the traction end of the foam supporting piece 20 to move to the end of the horizontal loop 412, the contact head 711 is still pushed by the limit block 120, so that the traction end of the flexible lifting bar 220 is in a vertical state, and the part of the flexible lifting bar 220 located at the starting end of the horizontal loop 412 is also in a vertical state due to the limitation of the retaining rod 130, that is, the flexible lifting bar 220 located in the horizontal loop 412 is in a vertical state.

[0045] The second step is flotation, in which air is introduced into the mixed slurry to form foam. The foam can float upward from between two adjacent flexible lifting strips 220 without affecting the formation of the froth layer.

[0046] The third step is collection. The traction device drives the traction rod 50 to move along the second loop 420. The traction rod 50 drives the traction end of the foam support piece 20 to move upward. The contact head 711 is still pushed by the limit block 120, so that the traction end of the flexible lifting strip 220 is in a vertical state; until the traction rod 50 moves to the end of the second loop 420, the contact head 711 moves along the inclined surface of the limit block 120, and the limit block 120 releases the push of the contact head 711, and the elastic potential energy stored in the spring 730 is released and pushes The rack 710 is reset, and the rack 710 drives the gear 720 to reverse to drive the traction end of the flexible lifting bar 220 to reset to a horizontal state; at this time, the linear drive member 810 drives the limit rod 80 to extend from the flotation tank 10, and the limit rod 80 releases the limit on the foam supporting member 20, and the retracting and discharging motor 310 drives the reel 30 to rotate to reel up the foam supporting member 20, so that each flexible lifting bar 220 maintains a horizontal tension state and continues to rise, and multiple flexible lifting bars 220 lift the foam layer upward to separate the foam layer from the slurry.

[0047] The fourth step is unloading. The traction device drives the traction rod 50 to move along the third loop 430. The traction rod 50 drives the traction end of the foam supporting piece 20 to move toward the slot 110. At the same time, the retracting motor 310 drives the reel 30 to rotate and continue to reel up the foam supporting piece 20. The foam supporting piece 20 drives the lifted foam layer to move toward the slot 110. The flushing nozzle 140 sprays water on the foam supporting piece 20 to flush the foam layer on the foam supporting piece 20 into the collecting tank 90.

[0048] In this way, a foam support 20 including a plurality of flexible lifting bars 220, a reel 30 for winding the foam support 20, a traction rod 50 for pulling the traction end of the foam support 20 to move along the guide rail 40, and a flipping device for driving each flexible lifting bar 220 to flip is provided in the flotation tank 10; the traction end of the foam support 20 is driven by the traction rod 50 to move along the first circuit 410 into the ore pulp, and at the same time, the flipping device drives each flexible lifting bar 220 to flip to a vertical state in the ore pulp, so that during the process of foam generation and flotation, the foam can float upward from between two adjacent flexible lifting bars 220 without affecting the formation of the froth layer; the traction end of the foam support 20 is driven by the traction rod 50 to move along the second circuit 420 so that the foam support 20 moves up from the ore pulp, and at the same time, the flipping device drives each flexible lifting bar 220 to flip to a vertical state in the ore pulp, so that during the process of foam generation and flotation, the foam can float upward from between two adjacent flexible lifting bars 220 without affecting the formation of the froth layer; The lifting bars 220 are restored to a horizontal state so that each flexible lifting bar 220 directly lifts up the froth layer to separate the froth layer from the slurry; the traction end of the froth supporting member 20 is driven by the traction rod 50 to move along the third loop 430 so that the froth supporting member 20 drives the froth layer to move toward the slot 110 to facilitate the collection of the froth layer; thus, by providing a reversible flexible lifting bar 220, the flexible lifting bar 220 can directly lift up the froth layer directly below the froth layer, reducing the flow of the froth layer during the froth collection process, thereby reducing the froth destruction caused by friction or collision, and at the same time avoiding the froth from staying in the flotation tank 10 for too long, which helps to maintain the uniformity and stability of the froth layer, and avoids the target mineral particles in the froth layer from sinking back into the slurry as much as possible, thereby effectively improving the sorting efficiency.
