Description

Technical Field

[0001] The present invention belongs to the technical field of mining agitation tanks, and particularly relates to a mining agitation tank with multiple layers of agitators. Background Art

[0002] As a key equipment in the ore dressing process, mining agitation tanks are widely used in the ore pulp agitation process before flotation. Their core function is to achieve the full mixing of ore pulp and reagents, laying the foundation for subsequent separation operations. Currently, this equipment has important applications in the fields of ferrous metal, non-ferrous metal ore dressing, chemical engineering, and sewage treatment, and its performance directly affects the ore dressing efficiency and resource recovery rate.

[0003] However, traditional mining agitation tanks generally adopt a single-layer stirring structure, relying on a single stirring rod for mixing operations, which exposes significant defects in actual operation: Firstly, due to the single stirring level, it is difficult for the ore pulp to form multi-directional eddies in the tank body, resulting in insufficient mixing uniformity. Especially when dealing with high-concentration and high-viscosity ore pulp, problems such as uneven distribution of reagents and insufficient reaction are likely to occur; secondly, the stirring rod is constantly subjected to the severe scouring and alternating stress of high-concentration ore pulp, and is prone to fatigue fracture or deformation, significantly increasing the equipment maintenance cost, and frequent shutdowns for maintenance affect the production efficiency.

The driving motor 61 drives the stirring main rod 24 to rotate through the transmission of the pulley 64 and the transmission belt 65. The stirring main rod 24 drives the upper stirring seat 3 and the lower stirring frame 4 to stir and mix pulp and liquid medicine, etc. The tension adjustment mechanism 7 is located in the middle of the transmission belt 65.

[0023] As can be seen from the above description, the present invention has the following beneficial effects: During use, the layered tank 2 is installed on the stirring bottom tank 11 as needed. At the same time, the connecting plug 25 and the connecting slot 26 are used to connect the stirring main rods 24 in series. And when the stirring main rod 24 rotates and stirs, the upper stirring seat 3 and the lower stirring frame 4 cooperate to push the pulp to roll up and down, inside and outside, for stirring, making the stirring more sufficient and thus enhancing the stirring efficiency of the stirring tank.

[0024] Embodiment Two: Please refer to Figures 1 to 8As shown, based on the first embodiment, the present invention provides a technical solution: The buffer protection mechanism 5 includes a buffer groove 51 opened on the surface of the main stirring rod 24 and a buffer seat 52 slidably installed in the buffer groove 51. The inner walls of the lower installation cylinder 41 and the upper installation cylinder 31 are fixedly connected to the buffer seat 52 by bolts. Buffer springs 53 are arranged on both sides of the buffer seat 52. The buffer springs 53 are supported in the buffer groove 51. Due to the concentration and weight of the pulp pressing on the upper stirring seat 3 and the lower stirring frame 4, during stirring, the buffer seat 52 can be driven to slide and press on the buffer springs 53 for buffering; A connecting clamp plate 58 is fixedly installed on the outer side of the buffer spring 53. A damping slider 57 is fixedly installed at the end of the connecting clamp plate 58. A damping sliding groove 56 is opened on the inner wall of the buffer groove 51. The damping slider 57 is slidably installed in the damping sliding groove 56. When the buffer spring 53 is stressed, it drives the connecting clamp plate 58 to move, causing the damping slider 57 to slide in the damping sliding groove 56 to further provide damping shock absorption; A damping guiding groove 55 is opened on the surface of the buffer seat 52. A damping guiding column 54 is installed inside the buffer groove 51. The buffer seat 52 is slidably installed on the damping guiding column 54 through the damping guiding groove 55. The damping guiding column 54 slides in the damping guiding groove 55 to provide damping shock absorption and ensure that the buffer seat 52 is more stable during installation and use.

[0025] For the buffer protection mechanism 5 adopting the above technical solution, during use, the buffer protection mechanism 5 buffers the connection between the lower stirring frame 4, the upper stirring seat 3 and the main stirring rod 24. It buffers through the support and elasticity of the buffer springs 53, and cooperates with the positioning and frictional damping of the damping guiding column 54 and the damping guiding groove 55 for shock absorption. At the same time, the damping sliding groove 56 and the damping slider 57 slide following the stress of the buffer spring 53 to further provide frictional damping to enhance the shock absorption ability, thereby reducing the collision between the pulp and the upper stirring seat 3 and the lower stirring frame 4 and reducing the occurrence of damage.

[0026] Further, it can be referred to Figure 1 、 Figure 7 and Figure 8, the tension adjustment mechanism 7 includes a positioning roller 77 rotatably installed in the main stirring seat 1, an adjustment seat 71 fixed in the main stirring seat 1, and an adjustment motor 74 fixedly installed at one end of the adjustment seat 71. An adjustment screw 72 is rotatably installed inside the adjustment seat 71 through a bearing. The output shaft of the adjustment motor 74 is fixedly connected to one end of the adjustment screw 72. An adjustment nut 73 is sleeved outside the adjustment screw 72. A sliding column 75 is rotatably installed outside the adjustment nut 73. By driving the adjustment screw 72 to rotate through the adjustment motor 74, the adjustment screw 72 drives the adjustment nut 73 and the sliding column 75 to move, so that the sliding column 75 presses on the transmission belt 65 for tension adjustment. A tension rod 78 is rotatably installed outside the sliding column 75. One end of the tension rod 78 is rotatably installed on the positioning roller 77. The position of the transmission belt 65 is positioned by the positioning roller 77 to ensure the stable connection between the transmission belt 65 and the pulley 64; a sliding groove 76 is opened at one end of the tension rod 78, and one end of the sliding column 75 is installed inside the sliding groove 76. During use, the connection is more stable through the guidance of the sliding groove 76 and the sliding column 75.

[0027] For the tension adjustment mechanism 7 adopting the above technical solution, during use, the main stirring rod 24 is driven from below by the driving mechanism 6, which does not affect the superimposed installation of the layered tank 2. And the tension of the transmission belt 65 is adjusted by the tension adjustment mechanism 7. And during the tension adjustment, the positioning of the positioning roller 77 does not affect the contact surface and angle change between the transmission belt 65 and the pulley 64, ensuring the stable transmission between the transmission belt 65 and the pulley 64 during the tension adjustment. Thus, the tension can be adjusted in real time, reducing the phenomena of noise and vibration during the tension adjustment.

[0028] Working principle and usage process of the present invention: When in use, according to needs, the tank body 21 can be fixed on the stirring bottom tank 11 through the connecting flange 22 to increase the height, so as to increase the processing space of the stirring tank. The main stirring rod 24 between the stirring bottom tank 11 and the stratifying tank 2 is snap-connected through the connecting plug 25 and the connecting slot 26. The driving motor 61 drives the main stirring rod 24 to rotate through the transmission of the pulley 64 and the transmission belt 65. The main stirring rod 24 drives the upper stirring seat 3 and the lower stirring frame 4 to stir and mix pulp, liquid medicine, etc. The pulp is pushed away by the rotation of the stirring push plate 32, and the pulp is sucked in by the rotation of the stirring suction plate 44, so that the pulp flows down to the upper stirring seat 3 at the bottom, so that the pulp circulates and tumbles in the stratifying tank 2 and the stirring bottom tank 11, thus ensuring better stirring and mixing effect. When in use, due to the concentration and weight of the pulp pressing on the upper stirring seat 3 and the lower stirring frame 4, it can be buffered by driving the buffer seat 52 to slide and press on the buffer spring 53. At the same time, the damping guide post 54 slides in the damping guide groove 55 to provide damping shock absorption, and drives the connecting splint 58 to move when the buffer spring 53 is stressed, so that the damping slider 57 slides in the damping chute 56 to further provide damping shock absorption. And when the transmission belt 65 runs for a long time, the phenomenon of loosening or tightening will occur. It can be adjusted by driving the adjusting screw 72 to rotate by the adjusting motor 74. The adjusting screw 72 drives the adjusting nut 73 and the sliding column 75 to move, so that the sliding column 75 presses on the transmission belt 65 for tension adjustment, and the position of the transmission belt 65 is positioned by the positioning roller 77 to ensure the stable connection between the transmission belt 65 and the pulley 64, reduce the noise and vibration during the tension change, and ensure more stable adjustment during use.
