Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of filtering treatment, and particularly relates to a gold mine tailings dehydration device. BACKGROUND

[0002] Tailings dehydration is a process that removes water from tailings through physical or chemical methods, allowing solid particles to separate from liquid, thereby reducing the volume of tailings and improving the efficiency of subsequent processing. The main principles include:

[0003] Gravity sedimentation: using gravity to make solid particles in tailings settle down, separating the upper clear water.

[0004] Centrifugal separation: using centrifugal force generated by high-speed rotation to separate solid particles from liquid.

[0005] Filtration: using the pores of filter cloth or filter screen to retain solid particles, and water passes through the pores.

[0006] Pressure dehydration: applying external pressure to squeeze water out of tailings.

[0007] In the gold ore dressing process, tailings dehydration is a key link to reduce the capacity of tailings pond, reduce the risk of environmental pollution, and realize the comprehensive utilization of resources. At present, for the dehydration of some gold mine tailings, there is a scheme in the prior art that uses filter plate pressing to process. The specific operation is as follows: the tailings to be dehydrated are laid on the filter plate, and then the filter plate and the tailings thereon are physically pressed by the pressing plate to forcibly discharge the water therein.

[0008] However, this dehydration method based on filter plate pressing has significant limitations. First, its operation process is discontinuous. Before each pressing dehydration operation, the addition of tailings must be stopped; and after the pressing dehydration is completed, the pressing must also be stopped before the processed tailings can be removed from the filter plate. This intermittent operation mode of "adding-stopping-pressing-stopping-removing" seriously restricts the processing efficiency and is difficult to meet the needs of large-scale tailings processing.

[0009] Secondly, in terms of dehydration effect, simple physical pressing can discharge part of the free water, but it is difficult to completely remove the capillary water and combined water adsorbed between tailings particles and inside. After pressing, the tailings are often compacted into hard lumps, which hinders the further diffusion and evaporation of water, making the dehydration process difficult to proceed, and ultimately resulting in a high overall moisture content of the tailings.

[0010] In summary, the existing filter plate pressing type tailings dehydration method not only has complicated operation and cannot be continuously performed, resulting in low processing efficiency, but also has unsatisfactory dehydration effect, with a large amount of water remaining in the tailings.

[0011] Based on this, the gold mine tailings dewatering device is designed to solve the above problems. SUMMARY

[0024] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are:

[0025] 1. The present invention adopts a rotating drum, a sliding push plate, a magnetic plate, a magnetic column, a driving motor, a filter plate and a vibrating motor. Under the action of the vibrating motor, the tailings form a continuously sliding flow state on the inclined filter plate. The driving motor drives the rotating drum and the sliding push plate to rotate synchronously, so that the tailings that continue to slide down on the upper side can automatically and continuously enter between two adjacent sliding push plates. This design completely gets rid of the operational limitations of traditional intermittent feeding, pressing and taking out, realizes the full continuity of tailings processing from feeding to dehydration, and greatly improves the overall operation efficiency. During the continuous conveying process, when the sliding push plate moves to the contact position with the arc section of the filter plate, the structural design enables the filter plate to effectively squeeze the sliding push plate, forcing it to move towards the built-in magnetic column. As the column moves, the space filled with tailings between the two sliding push plates is forcibly compressed. The moisture inside the tailings and in the gaps between the particles is efficiently squeezed out under the action of this high pressure. The released moisture can smoothly pass through the filter plate and flow into the wastewater collection frame below along the inclined surface. Compared with the traditional simple pressing, this device continuously squeezes and dehydrates the tailings during movement, which not only eliminates more free water, but also has a better removal effect on capillary water and part of the bound water, significantly reducing the final moisture content of the tailings; the compressed and dehydrated tailings, under the continued push of the sliding push plate, cross the push plate area and smoothly transition to the inclined short straight section of the filter plate, and then are continuously output. The entire processing process is smooth and compact, avoiding material accumulation and frequent start and stop operations.

[0026] 2. The present invention adopts an extrusion wheel, an extrusion groove, a connecting column, a movable frame, a guide hole, a breaking tooth and a heating side frame. The precise cooperation between the extrusion wheel and the extrusion groove is used to drive the connecting column to perform stable and controllable reciprocating motion in the horizontal direction. When the connecting column drives the movable frame to move to the left, the precise limiting effect of the guide hole ensures that the cylinder, the movable bar and the key component - the breaking tooth can be pushed to the left synchronously and orderly. These orderly arranged breaking teeth can efficiently push and crush the tailings that have been initially compressed into a ball, restoring it to a loose state. This process significantly improves the uniformity of the tailings and lays the foundation for subsequent more thorough dehydration treatment. Although simple physical breakup can improve the material state, the combination of effective thermal energy assistance can greatly improve the moisture removal efficiency. The present invention cleverly sets a heating side frame. After the breakup teeth complete the crushing and loosening operation of the tailings, the loose tailings immediately enter or closely contact the heating side frame area. The heating side frame continuously provides heat energy to act on the tailings particles that have been broken up and have increased surface area, accelerating the evaporation of moisture inside and on the surface. Compared with simple physical pressing or natural drying, this "breakup + heating" composite treatment method greatly enhances the moisture removal effect, can more effectively reduce the final moisture content of the tailings, and significantly shortens the overall drying cycle.

[0027] 3、The invention, adopt gas frame, contact plate, extrusion plate, air outlet valve, intercommunication plate and air jet head, when the extrusion plate moves to the left, strong extrusion is generated to the compressed gas in the gas frame, the compressed gas is forced to pass through the air outlet valve, air outlet pipe and intercommunication plate, and finally is high-speed sprayed through the uniformly distributed air jet head, the high-speed airflow accurately acts on the surface of the preliminarily compressed possible formed tailing agglomerate, strong impact and blowing effect are generated, the pneumatic auxiliary function is not isolated, but forms synergistic effect with the previously mentioned dispersing tooth function, the airflow blown by the air jet head can effectively loosen the external structure of the tailing agglomerate, and the subsequently followed dispersing tooth can more thoroughly break the internal part, the cooperation of the two makes the loosening effect of the tailing far exceed the single mechanical dispersing, and reaches a more ideal and uniform loosening state, the invention not only pays attention to the physical form of the material, but also focuses on the rapid removal of water, the high-speed flowing gas sprayed by the air jet head can significantly accelerate the evaporation process of the water in the surface and internal capillary channel of the tailing particle while completing the auxiliary function of dispersing, the continuously flowing airflow can continuously replace the saturated wet air around the tailing and keep a relatively low local humidity environment, which greatly promotes the transfer of water to the gas phase, effectively shortens the time required for water evaporation, the airflow auxiliary drying mode is combined with the heat energy auxiliary of the heating side frame, and a composite drying mechanism is formed, so that the internal water of the tailing can be more quickly and uniformly removed, and the overall drying efficiency is significantly improved.
