Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to a continuous treatment device for metal ore flotation wastewater. Background Technology

[0002] Flotation wastewater from metal mines is one of the major sources of industrial wastewater, with discharges reaching as high as 200 million tons per year. Due to limitations in existing mineral processing technologies, large amounts of toxic heavy metal ions and collectors remain in the flotation wastewater. These residual heavy metal ions and collectors can cause unintentional activation of minerals, altering the floatability and selectivity of the target minerals and severely impacting the stable operation of the flotation circuit.

[0003] To improve the separation performance of flotation, effectively removing the two types of pollutants coexisting in flotation wastewater—heavy metal ions and collectors—is essential for the recycling and reuse of flotation wastewater.

[0004] Because flotation wastewater contains complex components that interact and react with each other, forming compound pollutants, it severely hinders the recycling and reuse of flotation wastewater. Current technologies typically employ acid-base neutralization and precipitation for preliminary treatment. This method adjusts the pH of the flotation wastewater by adding acid or alkali agents to precipitate heavy metal ions. While simple to operate, this method generates a large amount of sludge. Furthermore, each treatment cycle requires natural settling or centrifugal separation to remove the precipitate, necessitating dedicated settling tanks or centrifuges, which encroaches on already limited mining space. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous treatment device for flotation wastewater of metal ores, so as to solve the technical problem that a separate settling space is required when treating flotation wastewater by acid-base neutralization in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A continuous treatment device for metal ore flotation wastewater includes: The sedimentation tank has a bottom that is tidally sealed by a telescopic baffle plate to simultaneously neutralize and settle the wastewater. When the baffle plate seals the bottom of the sedimentation tank, it forms a sludge settling zone. The sludge settled in the settling zone is treated and then discharged directly. At this time, the baffle plate acts as a temporary bottom plate to continue receiving new flotation wastewater. The baffle plate is also sealed by scraping the sludge into the settling zone through friction with the side wall of the sedimentation tank. A fine washing tank is located on one side of the sedimentation tank, and the sedimentation tank and the fine washing tank are connected by a flow pipe; The sedimentation tank adjusts the pH value of the flotation wastewater to neutralize and precipitate heavy metals at the bottom of the tank, thereby reducing the content of heavy metal ions. The neutralized and precipitated flotation wastewater flows into the washing tank to produce ferrite through co-precipitation of iron salts.

[0007] Furthermore, when the flotation wastewater is neutralized by acid and alkali in the sedimentation tank, the baffle is closed. When the flotation wastewater needs to be allowed to settle after the acid and alkali neutralization is completed, the baffle is opened and the wastewater enters the sludge settling area for natural settling. In subsequent continuous treatment, the baffle plate opens tidally according to the cycle of acid-base neutralization treatment to complete the natural transfer of flotation wastewater and the natural settling of sludge. After natural settling, the flotation wastewater enters the washing tank.

[0008] Furthermore, a raised floor is provided at the bottom of the sedimentation tank so that the bottom surface of the sedimentation tank is higher than that of the washing tank; A partition component is provided on the side of the sedimentation tank, and a three-dimensional slot is provided on the partition component. Rectangular openings communicating with the three-dimensional slot are provided around the sedimentation tank. Each three-dimensional slot of the partition component is equipped with a movable plate inside. The movable plates distributed around the sedimentation tank form baffles when the sedimentation tank is closed by the drive component.

[0009] Furthermore, an inner groove is provided on the outer side of the movable plate, and a guide strip is provided on the side wall of the sedimentation tank. When the movable plate is displaced by extending outward and retracting inward, it is limited by the mutual locking of the inner groove and the guide strip. On the moving plates moving in opposite directions, one of the moving plates has an extended protrusion on its side and the other moving plate has an inner groove on its side. When the moving plates are fully extended, they form a sealed baffle by locking each other.

[0010] Furthermore, a sealing strip is provided inside the three-dimensional slot near the rectangular opening. The sealing strip is used to completely seal the three-dimensional slot to prevent water from flowing into the three-dimensional slot. The sedimentation tank has pusher plates at the top and bottom of the rectangular opening on its side. The pusher plates are used to push the sludge off the moving plate when the moving plate retracts and moves inward.

[0011] Furthermore, each of the movable plates is provided with at least one automatic reset support assembly at its lower end. When the movable plate retracts, the automatic reset support assembly rotates to be close to the movable plate to house the automatic reset support assembly. When the movable plate extends, the automatic reset support assembly rotates to be perpendicular to the movable plate. At this time, the automatic reset support assembly is used to support the movable plate to bear the weight of the water. The automatic reset support assembly includes a fixed stake mounted on the movable plate and a rotating plate movably mounted on the fixed stake, with a support leg installed at the lower end of the rotating plate. A straight rod is installed between the two side plates of the fixed pile. The two side plates of the rotating plate are movably mounted on the straight rod and can rotate around the straight rod. A return spring is installed on the straight rod. When the moving plate extends, the return spring drives the support leg to rotate to a vertical position.

[0012] Furthermore, the side of the supporting leg is flush with the side of the rotating plate, and the supporting leg rotates with the rotating plate to approach the moving plate when the moving plate retracts.

[0013] Furthermore, the separating component has an open slot below the three-dimensional slot that corresponds to the installation position of the automatic reset support component; The lower end of the support leg may be provided with a widening plate, the size of which is larger than the cross-sectional size of the open groove; The open slot is equipped with an elastic sealing plate that can move along the cavity inside the open slot. The inner side of the elastic sealing plate is installed at the inner end of the open slot by a compression spring. When the moving plate extends, the elastic sealing plate closes the opening of the open slot. When the moving plate retracts, the elastic sealing plate is compressed by the support leg and retracts into the open slot.

[0014] Furthermore, the sedimentation tank is provided with inlet pipes around its bottom perimeter.

[0015] Furthermore, the separation assembly is provided with a sludge suction pipe on the side of the sludge settling zone.

[0016] Compared with the prior art, the present invention has the following advantages: This invention removes heavy metal ions from flotation wastewater in steps using two chemical precipitation methods. When a large amount of settled sludge is generated during the neutralization precipitation process, a retractable and movable baffle is used for tidal movement, thereby forming two layers of settling space from bottom to top in the settling tank. The sludge can be further detoxified in the bottom settling space to avoid environmental problems caused by direct discharge of settled sludge. The double-layer settling space can also improve the treatment efficiency of the settling tank. After neutralization, the baffle can be opened to send the settled sludge and wastewater into the bottom settling space for further settling, making full use of the three-dimensional space and ensuring continuous sedimentation.

Detailed Implementation

[0019] 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.

[0020] like Figure 1and Figure 2 As shown, the present invention provides a continuous treatment device for flotation wastewater of metal ore, including a sedimentation tank 1 and a washing tank 2 disposed on one side of the sedimentation tank 1. The sedimentation tank 1 and the washing tank 2 are connected by a flow pipe 3. The sedimentation tank 1 adjusts the pH value of the flotation wastewater to cause heavy metal ions to precipitate at the bottom of the tank. After the heavy metal ions in the sedimentation tank 1 are reduced by neutralization precipitation, the low-concentration heavy metal ion flotation wastewater flows into the washing tank 2. Iron salts are added to the low-concentration heavy metal ion flotation wastewater in the washing tank 2, and ferrite powder is produced from the wastewater by co-precipitation.

[0021] The sedimentation tank 1 is equipped with a retractable baffle 4 below the flow pipe 3. When the baffle 4 is extended, it forms a new bottom plate of the sedimentation tank 1, and the baffle 4 and the bottom of the sedimentation tank 1 form a sludge settling zone.

[0022] Specifically, the bottom of the sedimentation tank 1 is provided with inlet pipes 15 around its perimeter. Other secondary treatment substances are added to the sludge settling zone through the inlet pipes 15 to promote settling and reduce the toxicity of the sludge. This part will not be described in detail in this embodiment.

[0023] The separation component 5 is provided with a sludge extraction pipe 8 on the side of the sludge settling zone, which is used to extract sludge from the sludge settling zone.

[0024] The baffle plate 4 serves as a temporary bottom plate, and the sedimentation tank 1 above it serves as a temporary water collection tank to receive new flotation wastewater.

[0025] In this embodiment, both sedimentation tank 1 and washing tank 2 use chemical precipitation to remove heavy metals. Specifically, sedimentation tank 1 uses neutralization precipitation to remove heavy metal ions. This is achieved by adding an alkali agent to adjust the pH of the wastewater, causing the heavy metal ions to precipitate as hydroxides or carbonates. This method is simple to operate, but it generates a large amount of sludge.

[0026] The fine washing tank specifically uses the ferrite method to remove heavy metal ions from wastewater. This involves adding iron salts to the wastewater containing heavy metal ions and then using a co-precipitation method to extract ferrite powder from the wastewater. This method can remove multiple heavy metal ions at once, produces less sludge, has stable chemical properties, and is less likely to cause secondary pollution.

[0027] A retractable baffle 4 is installed at the lower end of the sedimentation tank 1. When the sludge at the bottom of the sedimentation tank 1 is settled, the baffle 4 extends to form a sludge settling zone at the bottom of the sedimentation tank 1.

[0028] The sedimentation tank 1 above the baffle 4 can be reused as a neutralization sedimentation tank for continuous sedimentation. Specifically, the flow pipe 3 is located at the upper end of the baffle 4, and its position is adjusted according to the weight of the baffle 4. Thus, the baffle 4 serves as both the top cover of the sludge settling zone and the bottom plate of the new sedimentation tank.

[0029] like Figure 3 As shown, in order to enable the baffle 4 to extend and retract, a partition component 5 is provided around the lower end of the sedimentation tank 1. The partition component 5 has a three-dimensional slot 51 inside, and rectangular openings 52 communicating with the three-dimensional slot 51 are provided around the sedimentation tank 1.

[0030] Each three-dimensional slot 51 of the partition component 5 is equipped with a movable plate 53. The movable plates 53 distributed around the sedimentation tank 1 are driven to extend and form the entire baffle 4. The baffle 4 and the bottom of the sedimentation tank 1 form a sludge settling zone.

[0031] The three-dimensional slot 51 serves as a space to accommodate the retraction of the movable plate 53. During normal use, the movable plate 53 retracts into the three-dimensional slot 51 under the drive of the drive component. At this time, the flotation wastewater in the sedimentation tank 1 generates a large amount of sludge through neutralization and sedimentation. When the amount of sludge reaches a certain height, it is necessary to push the movable plate 53 outward until all the movable plates 53 are fully extended to form the baffle plate 4.

[0032] At this time, the baffle plate 4 and the bottom of the sedimentation tank 1 form a sludge settling zone that can accommodate sludge. At this time, the sludge can be converted into harmless substances through biological treatment in the sludge settling zone.

[0033] The baffle 4 and the sedimentation tank above it form a new sedimentation space. After the flotation wastewater is poured into the new sedimentation space, sludge is formed on the upper surface of the baffle 4 by neutralization sedimentation. This does not hinder the normal wastewater treatment work. Since the flow pipe 3 is located above the baffle 4, the wastewater treatment work can be carried out normally above the baffle 4. After neutralization sedimentation, sludge is generated on the surface of the baffle 4, and the treated water flows to the washing tank 2 through the flow pipe 3.

[0034] After the sludge is discharged from the sludge settling zone, the driving component retracts the moving plate 53 into the three-dimensional slot 51. During the retraction process, the sludge on the moving plate 53 is pushed back to the bottom of the sedimentation tank 1, where it continues to neutralize and settle. At this point, the sedimentation tank 1 returns to its initial state. Once the amount of sludge reaches a certain height, the moving plate 53 needs to be pushed outward until all the moving plates 53 are fully extended to form the baffle plate 4. By repeating the above process, heavy metals can be removed from the flotation wastewater, and the generated sludge can be recycled and treated harmlessly.

[0035] like Figures 4 to 6 As shown, in order to ensure that all the movable plates 53 are locked together to form a relatively sealed baffle 4, the two sides of the two parallel movable plates 53 are close to the other two parallel sides of the sedimentation tank 1, and the two sides of the movable plates 53 are respectively provided with inner grooves 6.

[0036] Furthermore, guide strips 7 are provided on the other two parallel sides of the sedimentation tank 1. When the moving plate 53 extends outward and retracts inward, it moves to a limited position under the mutual locking action of the inner groove 6 and the guide strips 7.

[0037] The front sides of the two parallel movable plates 53 are also provided with inner grooves 6. After the two parallel movable plates 53 extend out, the other two parallel movable plates 53 move along the space formed by the two movable plates 53.

[0038] The other two parallel movable plates 53 are provided with extension protrusions on both sides. After the two parallel movable plates 53 are fully extended, they are mutually limited in movement by the locking action of the extension protrusions and the inner groove 6. When the four movable plates are fully extended, they form a sealed partition plate 4 by locking each other.

[0039] In this embodiment, two of the parallel moving plates 53 are named Plate 1 and Plate 2, and the other two parallel moving plates 53 are named Plate 3 and Plate 4. The sides of Plate 1 and Plate 2 are provided with grooves 6, and guide strips 7 are provided on the parallel sides of the sedimentation tank 1. When Plate 1 and Plate 2 move, they can be kept in a sealed state by the mutual locking action of the grooves 6 and guide strips 7.

[0040] The front sides of plates one and two are also provided with inner grooves 6. After plates one and two are completely moved outward, plates three and four are pushed outward at the same time. The extended protrusions of plates three and four are locked together with the inner grooves 6, so plates three and four can maintain a sealed state with plates one and two.

[0041] To further ensure the sealing of plates 1 and 2, and plates 3 and 4 when they are fully moved outward and fully retracted, a sealing strip 9 is provided inside the three-dimensional slot 51 near the rectangular opening 52. The sealing strip 9 is used to completely seal the three-dimensional slot 51 to prevent water from flowing into the interior of the three-dimensional slot 51.

[0042] In addition, such as Figure 3As shown, after the moving plate 53 becomes the new bottom plate of the sedimentation tank 1, it removes heavy metals under the chemical action of neutralization sedimentation, which produces some sludge. When the organic matter in the sludge is converted into harmless substances by biological treatment in the sludge settling zone, the moving plate 53 will retract toward the partition component 5. In order to remove the sludge on the moving plate 53 during the retraction, the side of the sedimentation tank 1 is provided with pusher plates 10 at the upper and lower ends of the rectangular opening 52. The pusher plates 10 are used to push off the sludge on the moving plate 53 when the moving plate 53 retracts and moves.

[0043] Furthermore, in this embodiment, the movable plate 53 can extend outward toward the sedimentation tank 1 and retract inward toward the separating component 5. Therefore, the driving component in this embodiment can drive the movable plate 53 to move inward and outward. The driving component is specifically a driving member that pushes the plate to move linearly. Therefore, the driving component in this embodiment is specifically a servo motor set above and below the movable plate 53. By using the forward and reverse rotation of the servo motor, the movable plate 53 is driven to move linearly inward and outward.

[0044] As another preferred embodiment of this implementation, such as Figure 3 , Figure 7 and Figure 8 As shown, in order to improve the weighing capacity of the entire baffle 4, at least one automatic reset support assembly 11 is provided at the lower end of each movable plate 53. When the movable plate 53 is retracted, the automatic reset support assembly 11 rotates to be close to the movable plate 53 to house the automatic reset support assembly 11. When the movable plate 53 is extended, the automatic reset support assembly 11 rotates to be perpendicular to the movable plate 53. At this time, the automatic reset support assembly 11 is used to support the movable plate 53 to bear the weight of the water.

[0045] The automatic reset support assembly 11 includes a fixed stake 111 mounted on a movable plate 53 and a rotating plate 112 movably mounted on the fixed stake 111. A support leg 113 is mounted on the lower end of the rotating plate 112.

[0046] A straight rod 114 is installed between the two side plates of the fixed pile 111. The two side plates of the rotating plate 112 are movably mounted on the straight rod 114 and can rotate around the straight rod 114. A return spring 115 is installed on the straight rod 114. When the moving plate 53 extends, the return spring 115 drives the support leg 113 to rotate to a vertical position.

[0047] The side of the support leg 113 is flush with the side of the rotating plate 112. When the moving plate 53 retracts, the support leg 113 rotates with the rotating plate 112 to be close to the moving plate 53.

[0048] The partition component 5 has an open slot 12 below the three-dimensional slot 51, which corresponds to the installation position of the automatic reset support component 11.

[0049] The automatic reset support assembly 11 provides support for the movable plate 53 in the following way: When the moving plate 53 is driven by the drive assembly to move toward the partition assembly 5, and the support leg 113 moves to the position of the open slot 12, the rotating plate 112 rotates around the straight rod 114, and the support leg 113 rotates to the lower surface of the moving plate 53 under the resistance of the open slot 12. At this time, the return spring 115 is in a stretched state, and the support leg 113 and the moving plate 53 retract into the partition assembly 5.

[0050] When the moving plate 53 is driven by the drive assembly to move towards the sedimentation tank 1, the support leg 113 automatically resets under the action of the return spring 115. The return spring 115 drives the rotating plate 112 to rotate in the opposite direction around the straight rod 114 until it rotates to be perpendicular to the moving plate 53. At this time, the lower end of the support leg 113 abuts against the bottom of the sedimentation tank 1. At this time, the moving plate 53 maintains a stable weighing capacity under the support of the support leg 113.

[0051] To prevent wastewater from flowing into the open slot, a widening plate can be installed at the lower end of the support leg 113. The size of the widening plate is larger than the cross-sectional size of the open slot 12. Therefore, the widening plate at the lower end of the support leg 113 can seal and block the opening of the open slot 12. Thus, when the moving plate 53 and the support leg 113 are retracted into the three-dimensional slot 51 and the open slot 12 inside the partition component 5, the opening can be completely blocked, preventing wastewater from entering the open slot.

[0052] On the other hand, the interior of the open groove 12 is provided with an elastic sealing plate 13 that can move along the cavity of the open groove 12. The inner side of the elastic sealing plate 13 is installed at the inner end of the open groove 12 by a compression spring 14. When the moving plate 53 extends, the elastic sealing plate 13 closes the opening of the open groove 12. When the moving plate 53 retracts, the elastic sealing plate 13 is compressed by the support leg 113 and retracts into the open groove 12.

[0053] This embodiment removes heavy metal ions from flotation wastewater using two chemical precipitation methods. Since the neutralization precipitation method generates a large amount of sludge, to reduce secondary pollution caused by sludge transfer, this embodiment specifically installs a retractable baffle at the bottom of the neutralization sedimentation tank. This baffle creates a sludge settling zone at the bottom of the sedimentation tank. By settling and detoxifying the sludge before transfer, secondary pollution can be reduced. The baffle, acting as a new bottom plate, ensures the sedimentation tank can continue its wastewater treatment process. Sludge settled on the baffle can be transferred to the bottom of the sedimentation tank when the baffle retracts, ensuring continuous sedimentation and sludge treatment.

[0054] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
