Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing equipment, in particular to an anti-clogging deep cone thickener structure. Background Art

[0002] With the rapid growth of new energy electric vehicles, the demand for lithium continues to increase. Lithium extraction from spodumene is no longer sufficient to meet market demand. Therefore, lithium extraction from lepidolite and its lithium-containing minerals will see significant growth, and the comprehensive utilization of lithium in lepidolite is crucial. To extract lithium from lepidolite and its lithium-containing minerals, mineral processing plants typically use gravity separation and flotation processes. Maintaining the production capacity of mineral processing plants is crucial. Regular mineral processing requires the use and replenishment of large quantities of water, with circulating water accounting for a significant portion of this water. Gravity separation and flotation processes impose specific water quality requirements. For proper operation, circulating water must be free of turbidity. Turbidity in circulating water is primarily caused by inadequate fines treatment, leading to research on comprehensive circulating water treatment. Thickeners are a commonly used type of purification and sedimentation equipment.

[0003] The thickener consists primarily of two main components: a circular thickening tank and a rake scraper. Solid particles suspended in the slurry in the thickening tank settle under gravity, leaving the upper portion as clarified water, enabling solid-liquid separation. The sludge deposited at the bottom of the thickening tank is continuously scraped by the rake scraper and discharged to the center of the tank bottom, while the clarified water overflows from the upper edge of the thickening tank. Existing thickeners are prone to clogging, which requires shutting down the thickener and clearing the blocked discharge pipe. This not only consumes significant manpower and material resources, impacting normal production efficiency, but also produces less than ideal results. Utility Model Content

[0004] In view of the shortcomings of existing thickeners, such as easy blockage, the need to shut down the thickener after blockage, and unsatisfactory unblocking effect, the applicant provides a rationally structured anti-blocking deep cone thickener structure, which can solve the problems of easy blockage and difficulty in cleaning, increase the fine mud settling area, and improve the sedimentation effect.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A blockage-resistant deep cone thickener structure comprises an upper cone, a lower cylinder and a cross bridge. The upper cone is located at the upper part of the lower cylinder and is interconnected with the lower cylinder. The upper cone adopts a polygonal cone formed by a plurality of inclined plates, and the lower cylinder adopts a polygonal cylinder formed by a plurality of vertical surfaces. A cross bridge is erected on the top of the upper cone, an upper pipe shaft is arranged at the central position of the cross bridge, a middle pipe shaft is coaxially arranged in the upper pipe shaft, the top of the middle pipe shaft is inserted into the upper pipe shaft, and the bottom of the middle pipe shaft is coaxially connected to a stirring shaft. A stirring frame is installed on the lower half of the stirring shaft, and the stirring frame extends into the internal cavity of the lower cylinder. A rotating motor assembly is also provided at the central position of the cross bridge to drive the stirring frame to rotate and stir inside the lower cylinder.

[0007] As a further improvement of the above technical solution:

[0008] The rotating motor assembly has a motor output shaft downward, which extends into the interior of the upper tube shaft. A driven matching plate is provided at the top end of the middle tube shaft, and a gear is provided on the outer periphery of the motor output shaft. The motor output shaft and the driven matching plate form a gear meshing fit.

[0009] The distribution range of the gears distributed on the motor output shaft in the vertical direction is greater than the thickness of the driven matching plate.

[0010] A bearing support frame is sleeved on the outer periphery of the lower cylinder, and a rotational fit is formed between the lower cylinder and the bearing support frame via a bearing assembly.

[0011] One end of the bearing support frame extends to the outside of the lower cylinder and is fixedly connected to the lifting frame. A lifting motor assembly is provided on the horizontal bridge, and the lifting motor assembly cooperates with the lifting frame.

[0012] A support frame is provided on the outer side surface of the upper cone, and the support frame is used for supporting the upper cone and the lower cylinder.

[0013] An overflow groove is provided on the outer periphery of the top opening of the upper cone, and the clarified liquid inside the upper cone overflows and is discharged to the outside through the overflow groove.

[0014] The beneficial effects of the utility model are as follows:

[0015] This new deep-cone thickener replaces the existing inclined tube thickener with an inclined plate thickener, resolving existing issues such as easy clogging and breakage of the inclined tube, difficulty in installation and cleaning, and inability to operate stably over a long period of time. The new thickener utilizes an inclined plate to increase the fine mud settling area, while the optimized cone angle shortens the settling time. The new design's agitator not only rotates and stirs but also rises and falls, providing enhanced settling and unblocking capabilities.

[0016] This utility model optimizes the deep cone thickener's inclined plate form and cone angle adjustment, thereby optimizing the deep cone thickener's equipment, increasing the sedimentation rate of fine mud and significantly improving the sedimentation effect. This utility model can reduce the mud content in circulating water, ensure the quality of circulating water, greatly improve production efficiency, ensure production continuity, and guarantee economic benefits.

[0020] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] Various aspects of the present invention will be described below with reference to the accompanying drawings, which are schematic illustrations of idealized configurations of the present invention. As such, variations in the shapes of these illustrations are to be expected, for example, as a result of manufacturing techniques and / or tolerances. The various aspects of the present invention shown in the drawings may not necessarily be drawn to scale. Furthermore, some of the drawings have been simplified for the sake of clarity. Consequently, the drawings may not depict all of the various components of a given apparatus (e.g., device) or method. Therefore, the components shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shape of the components and are not intended to limit the scope of the present invention.

[0022] Reference Figures 1 to 2 As shown, the anti-clogging deep cone thickener structure described in the present invention includes an upper cone 1, a lower cylinder 2, and a cross bridge 3. The upper cone 1 is located above the lower cylinder 2 and is interconnected with the lower cylinder 2. The upper cone 1 is a polygonal cone formed by a plurality of inclined plates, with the opening facing upward. The lower cylinder 2 is a polygonal cylinder formed by a plurality of vertical surfaces. The interiors of the upper cone 1 and the lower cylinder 2 are connected cavities. The upper cone 1 and the lower cylinder 2 form a funnel-shaped structure, which together constitute a container for the concentrated liquid to be processed. The present invention uses a cone composed of multiple inclined plates to increase the fine mud settling area, and the optimization of the cone angle shortens the settling time.

[0023] A cross bridge 3 is provided at the top of the upper cone 1, and an upper shaft 5 is provided in the center of the cross bridge 3. The upper shaft 5 is a tubular structure and is arranged in the vertical direction. A middle shaft 6 is coaxially arranged in the upper shaft 5. The top of the middle shaft 6 is inserted into the upper shaft 5, and the bottom of the middle shaft 6 is coaxially connected to a stirring shaft 7. A stirring frame 8 is installed on the lower half of the stirring shaft 7. The stirring frame 8 extends into the internal cavity of the lower cylinder 2 and can rotate and stir inside the lower cylinder 2. A support frame 4 is provided on the outer surface of the upper cone 1. The support frame 4 is used to support the structure of the upper cone 1 and the lower cylinder 2, so that the upper cone 1 and the lower cylinder 2 are placed vertically and stably.

[0024] A rotating motor assembly 9 is also located in the center of the crossbar 3. This assembly has a motor output shaft 10 extending downwardly, extending into the interior of the upper tubular shaft 5. Gears are arranged on the outer circumference of the motor output shaft 10. A driven mating plate 11 is located at the top of the middle tubular shaft 6. The motor output shaft 10 extends into the interior of the upper tubular shaft 5 and forms a gear meshing engagement with the driven mating plate 11. The gears on the motor output shaft 10 are distributed vertically over a greater range than the thickness of the driven mating plate 11.

[0025] A bearing support frame 12 is sleeved on the outer periphery of the lower cylinder 2, and a rotational fit is formed between the lower cylinder 2 and the bearing support frame 12 via a bearing assembly. One end of the bearing support frame 12 extends to the outside of the lower cylinder 2 and is fixedly connected to the lifting frame 13. A lifting motor assembly 14 is provided on the cross bridge 3, and the lifting motor assembly 14 cooperates with the lifting frame 13 to drive the lifting frame 13 up and down. An overflow trough 15 is provided on the outer periphery of the top opening of the upper cone 1, and the clarified liquid inside the upper cone 1 overflows and is discharged to the outside through the overflow trough 15. Under the action of the static pressure of the liquid, solid particles such as fine mud or slurry with a higher concentration in the liquid will freely settle into the lower cylinder 2 and be discharged through the discharge port on the lower cylinder 2.

[0026] When the sedimentation effect needs to be improved or a blockage occurs, the lifting motor assembly 14 can cooperate with the lifting frame 13 to drive the bearing support frame 12 and the lower cylinder 2 up and down. The vertical distribution range of the gears distributed on the motor output shaft 10 is greater than the thickness of the driven matching plate 11, so that the motor output shaft 10 and the driven matching plate 11 always maintain gear meshing cooperation, thereby driving the stirring shaft 7 and the stirring frame 8 to move up and down. Therefore, the stirring frame 8 not only rotates and stirs but also can move up and down, achieving a better sedimentation effect and clearing the blockage.

[0027] During implementation, the upper cone 1 is first filled with circulating production water or ore slurry to be clarified. A settling agent is then added. Under the hydrostatic pressure of the liquid, fine mud or solid particles, such as ore slurry, with a higher concentration, freely settle into the lower cylinder 2 and are discharged through the discharge port on the lower cylinder 2. The upper cone 1 utilizes multiple inclined plates to increase the fine mud settling area, and the optimized cone angle shortens the settling time. Furthermore, during operation, the stirring action of the stirring frame 8 further concentrates the solid particles and allows them to be discharged from the lower cylinder 2.

[0028] When a blockage occurs, the lifting motor assembly 14 cooperates with the lifting frame 13 to drive the bearing support frame 12 and the lower cylinder 2 up and down. The vertical distribution range of the gears distributed on the motor output shaft 10 is greater than the thickness of the driven matching plate 11, so that the motor output shaft 10 and the driven matching plate 11 always maintain gear meshing, thereby driving the stirring shaft 7 and the stirring frame 8 to move up and down. Therefore, the stirring frame 8 not only rotates and stirs but also can move up and down, achieving a better sedimentation effect and clearing the blockage.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
