Description

Technical Field

[0001] This utility model relates to the field of mineral processing wastewater technology, specifically a device for mineral sedimentation in a concentration tank. Background Technology

[0002] Mineral processing is a process that, based on the physical and chemical properties of different minerals in an ore, involves crushing and grinding the ore, and then using methods such as gravity separation, flotation, magnetic separation, and electrostatic separation to separate valuable minerals from gangue minerals, and to separate various associated (symbiotic) valuable minerals as much as possible, removing or reducing harmful impurities to obtain raw materials needed for smelting or other industries. The wastewater remaining after mineral processing is characterized by large volume, high suspended solids content, and a variety of harmful substances at low concentrations. Its main harmful substances are heavy metal ions and mineral processing reagents. Heavy metal ions include copper, zinc, lead, nickel, iron, barium, cadmium, as well as arsenic and rare elements. Mineral processing plants generally use thickening tanks for wastewater treatment and for enriching and recovering fine-grained valuable minerals.

[0003] Because the minerals undergo flotation, the waste liquid contains a large amount of residual reagents and carries some fine minerals. During the process of entering the thickening tank, mineral foam is easily formed and spreads across the entire liquid surface, making it difficult for fine minerals to settle. A large portion of the fine minerals overflows with the liquid surface, resulting in the loss of valuable metals. The loss of metals is related to the heavy metal content of the overflow water, which directly affects the treatment effect of environmental wastewater. Utility Model Content

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0028] like Figures 1-2 As shown, this application provides a device for mineral settling in a thickening tank, comprising: a thickening tank 1; a drive shaft 4 disposed within the thickening tank 1; a moving mechanism 2 disposed at the top of the thickening tank 1, one end of which overlaps with the thickening tank 1, and the other end is connected to a transmission component, the transmission component being connected to the drive shaft 4, the moving mechanism 2 moving along the top of the thickening tank 1 and cooperating with the transmission component to drive the drive shaft 4 to rotate; a fence 6 sleeved on the drive shaft 4 and fixedly connected to the transmission component; and a spraying mechanism 5 disposed on the drive shaft 4 and located above the fence 6 for spraying foam within the fence 6.

[0029] Wastewater is treated by adding flocculant to thickening tank 1. The moving mechanism 2 moves along the top of thickening tank 1 and works with the transmission components to drive the transmission shaft 4 to rotate. At this time, the fence 6 rotates together with the transmission shaft 4. The fence 6 can prevent the generated mineral foam from spreading, thus enriching and thickening it. The spraying mechanism 5 on the fence 6 sprays the foam in the fence 6 to accelerate the dissolution and sedimentation of the mineral foam. The minerals entrained in the suspended foam layer of valuable metals will quickly sink. The sedimented bottom sludge material is dewatered by a ceramic filter and made into tungsten fine sludge product to prevent the loss of valuable metals, improve water quality, and ensure the effect of wastewater treatment.

[0030] Specifically, such as Figure 1 As shown, the moving mechanism 2 includes a drive motor, and the output end of the drive motor is connected to a roller, which is rolled on the thickening tank 1.

[0031] The moving mechanism 2 drives the rollers to roll on the thickening tank 1, thereby driving the transmission components to move, and driving the transmission shaft 4 to rotate through the transmission components.

[0032] Specifically, the roller is provided with a tooth, and the thickening tank 1 is provided with a tooth groove at the position corresponding to the tooth.

[0033] By setting the cooperation of the tooth and the tooth groove, the movement of the roller along the top of the thickening tank 1 can be ensured, and the sliding or disengagement of the roller from the top of the thickening tank 1 can be prevented, thereby ensuring the stability of the device during operation.

[0034] Specifically, as shown in Figure 1 The transmission member includes a rotating rake frame 3, the driving motor is fixed at one end of the rotating rake frame 3, and the other end of the rotating rake frame 3 is fixedly connected with the transmission shaft 4.

[0035] The driving motor is fixed at one end of the rotating rake frame 3, and the other end of the rotating rake frame 3 is fixedly connected with the transmission shaft 4, so that when the driving motor drives the roller to move, the rotating rake frame 3 can be driven to move at the same time, and the transmission shaft 4 can be driven to rotate.

[0036] Specifically, as shown in Figure 1 The fence 6 is a square with a size of 4m*4m, the height of the fence 6 is 0.5m, and the fence 6 is located 0.25m above and below the water surface liquid.

[0037] The fence 6 with this specification is convenient to install on the rotating rake frame 3, and there are fences 6 above and below the water surface liquid, which can accelerate the enrichment and thickening of the mineral foam to make it not easy to diffuse.

[0038] Specifically, as shown in Figure 2 The spraying mechanism 5 includes a spraying pipe, one end of the spraying pipe is fixed on the transmission shaft 4, and the other end is connected with a spraying head; the spraying mechanism 5 is provided with multiple groups, and is arranged around the transmission shaft 4.

[0039] Multiple groups of spraying pipes are arranged around the transmission shaft 4, and multiple groups of spraying heads spray into the fence 6, which can spray the suspended mineral foam in the fence 6 in all directions, so that the foam in the fence 6 can quickly sink after ablation.

[0040] Specifically, as shown in Figure 1 The bottom of the inner wall of the thickening tank 1 is provided with an inclined plate 101, the bottom of the thickening tank 1 is provided with a discharge pipe 103, and the connection between the inclined plate 101 and the discharge pipe 103 is provided with a discharge port 102.

[0041] The inclined plate 101 can improve the settling speed, the settled matter can be output through the discharge pipe 103, and the discharge port 102 can prevent the settled matter from accumulating at the connection between the inclined plate 101 and the discharge pipe 103, thereby ensuring the output of the settled matter.

[0042] Specifically, as shown in Figure 1 The bottom of the transmission shaft 4 is provided with a stirring rod 7, and the stirring rod 7 is arranged in parallel with the inclined plate 101.

[0043] When the transmission shaft 4 rotates, the stirring rod 7 can be driven to stir the bottom of the concentration tank 1, so as to prevent the accumulation of the precipitate.

[0044] Specifically, as shown in the figure, Figure 1 The bottom of the concentration tank 1 is provided with a valve 8.

[0045] The valve 8 can be used to open or close the discharge pipe 103, so as to ensure that the precipitate is output after the precipitation is completed.

[0046] Those skilled in the art should understand that the above discussion of any embodiment is only exemplary; under the idea of the present application, the above embodiments or technical features in different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for the sake of simplicity.
