Description

Technical Field

[0001] This invention relates to the field of thickener technology, and more specifically to an intelligent feeding device for a thickener. Background Technology

[0002] A thickener uses gravity to allow solid particles suspended in a liquid to settle to the bottom, while the clear liquid is discharged. In existing technology, the suspension to be treated is generally sent into the thickener, and the solid particles settle to the bottom of the thickener under gravity, forming a thick sediment layer. The clear liquid then rises through the sediment layer to the top and is discharged through the overflow port.

[0003] However, the above-mentioned feed device for the thickener still has the following defects:

[0004] Relying solely on gravity settling results in a long separation time between the sediment and the clear liquid, affecting treatment efficiency. Although introducing a stirring structure can improve sedimentation efficiency, this may cause water flow disturbance, which in turn affects the formation of the upper clear liquid.

[0005] Because different types of mineral slurries have different viscosities and particle sizes, a stable feed is particularly important for some heavy metal slurries. Traditional baffles used to slow down ordinary mineral slurries may not be effective in reducing the flow rate of these slurries; especially when the slurry flow rate increases, if the diameter of the discharge pipe remains unchanged, the discharge speed of the slurry will increase, further affecting the stability of the feed. Summary of the Invention

[0006] In order to overcome the above-mentioned technical problems, the present invention aims to provide an intelligent feeding device for a thickener, which solves the problem mentioned in the background art that although the existing thickener feeding device can improve sedimentation efficiency by introducing a stirring structure, it will cause water flow disturbance, affect the formation of the upper clear liquid, and thus affect the flocculation treatment efficiency.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0010] The isolation wheel has a through groove on the isolation seat, and the isolation wheel is connected to the through groove and rotates around its axis; the isolation wheel abuts against the side wall of the through groove; the isolation wheel is covered with a flexible rubber layer; when the flocculated material and crushed stone settle and squeeze the isolation wheel, the flocculated material and crushed stone squeeze the flexible rubber layer under the action of gravity, and drive the isolation wheel to rotate, so that the flocculated material and crushed stone pass through the isolation wheel and are discharged downward.

[0011] Preferably, a stirring mechanism is also provided inside the conical cylinder. The stirring mechanism includes a motor, a stirring rod, and a spiral blade. The motor is installed in the conical cylinder, one end of the stirring rod is coaxially connected to the motor, the other end of the stirring rod is rotatably connected to the isolation seat, and the spiral blade is disposed on the stirring rod and below the isolation seat.

[0012] Preferably, a cylindrical tube is provided at the bottom end of the conical tube; the blade width of the helical blade gradually decreases from the bottom to the top, and the widest position of the helical blade is located inside the cylindrical tube.

[0013] Preferably, a control mechanism is also provided inside the conical cylinder; the control mechanism is used to drive the isolation wheel to rotate so as to discharge the flocculated material and gravel that have settled on the isolation seat.

[0014] Preferably, the control mechanism includes a linkage mechanism and an elastic airbag; the linkage mechanism includes a driving helical gear and a driven helical gear; the driving helical gear is coaxially connected to the stirring rod, and the driven helical gear is coaxially connected to the isolation wheel; the elastic airbag is disposed inside the isolation wheel.

Each pair of isolation wheels is rotatably connected to a through slot around its axis, and each pair of isolation wheels abuts against each other.

[0016] Each isolating wheel is coaxially connected to a spur gear at its end. The spur gears on each pair of isolating wheels mesh with each other, and the driven helical gear is coaxially connected to one of the isolating wheels in each pair.

[0017] The isolating wheel has a conical structure, with the larger diameter end of the conical structure lower than the smaller diameter end; the spur gears are connected to the isolating wheel via a universal joint, so that when the isolating wheel rotates around its axis, the spur gears on the pair of isolating wheels always remain in a meshed state.

[0018] Preferably, the control mechanism further includes a pressure regulating mechanism; the pressure regulating mechanism includes a threaded rod and a piston; the threaded rod is threadedly connected to an isolation wheel, the isolation wheel has a groove, the groove communicates with the interior of the elastic air bladder, the piston is slidably connected to the groove, and the threaded rod is connected to the piston.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figure 1-10 As shown, an intelligent feeding device for a concentrator, such as Figure 1-4 and Figure 6 As shown, it includes a conical cylinder 1; a top cover 2 is provided on the conical cylinder 1, and an overflow hole 3 is provided at the top of the conical cylinder 1 near the top cover 2; when flocculation reaction occurs in the conical cylinder 1, the clear water at the top of the conical cylinder 1 overflows through the overflow hole 3; a settling mechanism 4 is provided inside the conical cylinder 1; the settling mechanism 4 includes: an isolation seat 41, which is provided inside the conical cylinder 1; an isolation wheel 43, on which a through groove 42 is opened, and the isolation wheel 43 is rotatably connected to the through groove 42 around its axis; the isolation wheel 43 abuts against the side wall of the through groove 42; the isolation wheel 43 is covered with a flexible rubber layer; when the flocculated material and gravel settle and squeeze the isolation wheel 43, the flocculated material and gravel squeeze the flexible rubber layer under the action of gravity, and drive the isolation wheel 43 to rotate, so that the flocculated material and gravel pass through the isolation wheel 43 and are discharged downward.

[0041] It should be noted that when flocculant is introduced into the conical cylinder 1 above the isolation seat 41, after the flocculant mixes with the slurry, the fine particles in the slurry aggregate into larger flocs through flocculation and settle down. This causes the flocculants and gravel to accumulate on the isolation wheel 43. As the flocculation reaction progresses, the flocculants exert greater pressure on the isolation wheel 43 under the influence of gravity, causing the isolation wheel 43 to deform and compress the flexible rubber layer. This deformation, driven by gravity, causes the isolation wheel 43 to rotate, allowing some of the flocculants and gravel to pass through the gap between the isolation wheel 43 and the through groove 42 and be discharged downwards. In other words, some sediment can be discharged during the flocculation reaction, reducing the amount of flocculants and gravel in the slurry, which facilitates the subsequent flocculation reaction rate and allows for the discharge of a higher concentration of slurry, achieving the initial concentration purpose and thus improving the working efficiency of the thickener.

[0042] like Figure 1-5 As shown, a stirring mechanism 5 is also provided inside the conical cylinder 1. The stirring mechanism 5 includes a motor 51, a stirring rod 52, and a spiral blade 53. The motor 51 is installed in the conical cylinder 1 and the top cover 2. One end of the stirring rod 52 is coaxially connected to the motor 51, and the other end of the stirring rod 52 is rotatably connected to the isolation seat 41. The spiral blade 53 is provided on the stirring rod 52 and is located below the isolation seat 41. A cylindrical cylinder 54 is provided at the bottom end of the conical cylinder 1. The blade width of the spiral blade 53 gradually decreases from the bottom to the top, and the widest part of the spiral blade 53 is located inside the cylindrical cylinder 54.

[0043] It should be noted that when the high-concentration slurry passing through the channel 42 falls onto the spiral blades 53 inside the cylindrical cylinder 54, it will not quickly pass through the spiral blades 53 to be discharged due to its high concentration. At this time, the motor 51 drives the spiral blades 53 to rotate in the forward direction, pushing the slurry upward, which stirs the slurry inside the cylindrical cylinder 54, improving the uniformity of the slurry and the flocculation effect. At the same time, the discharge speed of the slurry inside the cylindrical cylinder 54 can be controlled to facilitate the feeding of the slurry into the thickener. When too much slurry clogs the cylindrical cylinder 54, the motor 51 drives the spiral blades 53 to rotate in the reverse direction, pushing the slurry downward to facilitate its discharge.

[0044] Understandably, the structure of the spiral blade 53 with its blade width gradually decreasing from bottom to top allows the conical cylinder 1 to have a large stirring space, which facilitates mixing. When the spiral blade 53 rotates in the forward direction, it drives the slurry upward and spreads around the spiral blade 53, and with the help of gravity, it forms a certain circulation motion, which improves mixing. When the slurry is blocked and the spiral blade 53 rotates in the reverse direction, because the top blade of the spiral blade 53 is narrower, less slurry is pushed downward, which can reduce the pressure on the side wall of the conical cylinder 1 and the spiral blade 53, and prevent the conical cylinder 1 and the spiral blade 53 from being damaged by excessive force.

[0045] like Figure 2-4As shown, a control mechanism 6 is also provided inside the conical cylinder 1; the control mechanism 6 is used to drive the isolation wheel 43 to rotate so as to discharge the flocculated material and gravel that have settled on the isolation seat 41.

[0046] It should be noted that when the pressure of the settled flocs and gravel on the isolation wheel 43 is small and cannot be directly discharged by gravity, the control mechanism 6 drives the isolation wheel 43 to rotate, so that the flocs and gravel located between the isolation wheel 43 and the through channel 42 are squeezed out. By using the control mechanism 6 in conjunction with the isolation wheel 43, the purpose of actively discharging the flocs and gravel located at the bottom of the slurry can be achieved, and the rotation speed of the isolation wheel 43 can be controlled to control the discharge speed of the thicker slurry.

[0047] like Figure 8-9 As shown, the control mechanism 6 includes a linkage mechanism 61 and an elastic airbag 62; the linkage mechanism 61 includes a driving helical gear 611 and a driven helical gear 612; the driving helical gear 611 is coaxially connected to the stirring rod 52, and the driven helical gear 612 is coaxially connected to the isolation wheel 43; the elastic airbag 62 is disposed inside the isolation wheel 43.

[0048] It should be noted that when the motor 51 drives the stirring rod 52 to rotate, it drives the active helical gear 611 to rotate, which in turn drives the driven helical gear 612 to rotate, which in turn drives the isolation wheel 43 to rotate. The rotation of the isolation wheel 43 squeezes the flocculated material and gravel downwards, allowing the flocculated material and gravel to be discharged downwards. The elastic airbag 62 improves the deformability of the isolation wheel 43, making it easier to discharge larger flocculated material and gravel.

[0049] like Figure 5 and Figure 7-8 As shown, multiple pairs of isolation wheels 43 are disposed on an isolation seat 41. The isolation seat 41 has multiple through slots 42. Each pair of isolation wheels 43 is rotatably connected to a through slot 42 around its axis, and each pair of isolation wheels 43 abuts against each other. Each end of each isolation wheel 43 is coaxially connected to a spur gear 614. The spur gears 614 on each pair of isolation wheels 43 mesh with each other, and the driven helical gear 612 is coaxially connected to one of the isolation wheels 43 in each pair of isolation wheels 43. The isolation wheel 43 has a conical structure, and the large-diameter end of the conical structure is lower than the small-diameter end. It can be understood that the large diameter is relative to the small diameter. The spur gear 614 is connected to the isolation wheel 43 through a universal joint 613 so that when the isolation wheel 43 rotates around its axis, the spur gears 614 on a pair of isolation wheels 43 always remain in a meshed state.

[0050] It should be noted that by setting the conical structure of the isolation wheel 43, and with the large-diameter end of the conical structure being lower than the small-diameter end, the heavier and larger flocculated material and gravel come into contact with the larger cross-section of the cone. This position can produce greater deformation, which facilitates the discharge of large-volume flocculated material and gravel and improves the discharge efficiency.

[0051] like Figure 8-10 As shown, the control mechanism 6 also includes a pressure regulating mechanism 63; the pressure regulating mechanism 63 includes a threaded rod 631 and a piston 633; ​​the threaded rod 631 is threadedly connected to the isolation wheel 43, the isolation wheel 43 has a groove 632, the groove 632 communicates with the interior of the elastic airbag 62, the piston 633 is slidably connected to the groove 632, and the threaded rod 631 is connected to the piston 633; ​​the pressure regulating mechanism 63 also includes a top plate 634 and a spring 635; the top plate 634 is connected to the threaded rod 631, and the spring 635 is disposed between the top plate 634 and the piston 633.

[0052] It should be noted that, in order to control the degree of deformation of the isolation wheel 43 and thus control the output concentration of the slurry after flocculation, the threaded rod 631 is rotated to move the top plate 634, which in turn pushes the spring 635 to move, causing the piston 633 to slide in the groove 632, thereby adjusting the air pressure in the elastic airbag 62 and achieving the purpose of controlling the degree of deformation of the isolation wheel 43. Furthermore, when the isolation wheel 43 is subjected to a large force, the increased air pressure can push the spring 635 to further compress, thereby offsetting part of the deformation of the isolation wheel 43 and preventing the isolation wheel 43 from being damaged due to excessive force.

[0053] like Figure 1-10 As shown, a controller is installed on the top cover 2, and a liquid concentration sensor is installed at the bottom of the conical cylinder 1. The liquid concentration sensor is used to detect the concentration of the liquid introduced into the stirring mechanism 5. The motor 51 and the liquid concentration sensor are both electrically connected to the controller. It is understood that the controller and the liquid concentration sensor are existing technologies and are not shown in the figure. They will not be described in detail here.

[0054] It should be noted that the concentration of the slurry in the cylindrical cylinder 54 is detected by a liquid concentration sensor and the relevant data is transmitted to the controller. The controller controls the power of the motor 51 based on the received data, thereby controlling the stirring speed of the slurry in the cylindrical cylinder 54, and thus controlling the speed at which the slurry in the conical cylinder 1 is discharged into the cylindrical cylinder 54 and the speed at which the slurry in the cylindrical cylinder 54 is discharged into the thickener.

[0055] In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "multiple" means two or more.

[0056] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0057] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
