Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a wastewater treatment device for sulfide ore flotation. Background Art

[0002] Sulfide ore flotation is a mineral processing method that utilizes the differences in physical and chemical properties of mineral surfaces, especially hydrophobicity, to separate and enrich useful minerals from sulfide ore. A large amount of wastewater is generated during the sulfide ore flotation process. If this wastewater is directly discharged, it will not only waste water resources, but also cause serious pollution to the environment. Therefore, it is necessary to treat the sulfide ore flotation wastewater to achieve the recycling of water resources and environmental protection.

[0003] Chinese patent publication number CN118206252B discloses a wastewater treatment device and method for zirconium-titanium ore flotation. Its structure includes a working barrel, which pours wastewater into the interior of a primary filter housing through a discharge hopper. The motor is started, the motor drives the rotating shaft to rotate, the rotating shaft drives the rotating shell to rotate, the rotating shell drives the movable flexible plate to rotate, the movable flexible plate drives the bending rod to rotate, and the bending rod drives the protective plate to rotate. During the rotation of the protective plate, the wastewater is pushed through the primary filter housing to the top of the working barrel. Heavy metal impurities in the wastewater will be blocked by the primary filter housing. When the work continues, the accumulated heavy metal impurities generate a reaction force, causing the protective plate to move, and the protective plate drives the movable flexible plate to move. Negative pressure is generated during the movement of the movable flexible plate, and the falling wastewater is absorbed into the interior of the rotating shell through the circular hole, and comes into contact with the activated carbon plate, thereby performing preliminary purification of the wastewater.

[0004] However, the above-mentioned prior art has the following shortcomings: during use, although the filter holes on the filter screen can be cleaned to prevent the filter holes from being blocked, the impurities cleaned out are still inside the wastewater treatment device, causing the internal environment of the wastewater treatment device to continue to deteriorate. The accumulation of impurities will gradually occupy the effective space in the device, hindering the normal flow path of the liquid in the device, and greatly reducing the treatment efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a wastewater treatment device for sulfide ore flotation in order to solve the problem that, during use, although the filter holes on the filter screen can be cleaned to prevent the filter holes from being blocked, the impurities cleaned out still remain inside the wastewater treatment device, causing the internal environment of the wastewater treatment device to continue to deteriorate, and the accumulation of impurities will gradually occupy the effective space in the device, hindering the normal flow path of the liquid in the device, and greatly reducing the treatment efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The dosing device in this invention utilizes the gravity of the wastewater to drive the receiving barrel up and down. Combined with the linkage of the spiral guide column and the blocking plate, it realizes the automatic opening and closing of flocculant dosing and quantitative control. Multiple groups of drug storage boxes are combined with U-shaped push-out plates to ensure uniform dispersion of the drug and prevent clogging. The vortex formed by the triangular blocking plate enhances the mixing effect of the flocculant and wastewater, promoting the rapid coagulation of suspended particles.

No additional power is required to complete the filter surface cleaning. The J-shaped collection plate and the C-shaped extrusion plate work together to squeeze and dehydrate the impurities. The separated water flows back to the water inlet bucket, and the solid impurities are discharged through the guide plate. This reduces the subsequent processing load, reduces the frequency of manual cleaning, prevents filter pores from being clogged, and maintains a stable filtration flux. The compact structure and low energy consumption effectively improve the efficiency and continuity of solid-liquid separation.

[0020] 3. Through the second filter device, the mechanical linkage of the hydraulic rod and the spiral guide block realizes the uninterrupted rotation switching of the adsorbent. The saturated filter box can be removed and the unused filter box can be moved to the working position without stopping the machine. The modular design of multiple sets of fan-shaped filter boxes facilitates independent maintenance. The conical structure of the guide tube optimizes the water flow distribution, ensuring that the wastewater passes through the activated carbon layer evenly and improving the adsorption effect. The cooperation of the T-shaped rotating block and the annular groove enhances the rotation stability and avoids jamming. This device significantly improves the processing efficiency, reduces the replacement cost, and ensures the continuous high efficiency and convenient maintenance of the secondary filtration.

[0036] Reference Figures 2 to 6The dosing device 3 includes a receiving barrel 31 that is slidably connected to the inner wall of the water inlet barrel 2. The top of the receiving barrel 31 is fixedly connected to a spring 1 33. There are multiple groups of springs 1 33, which are evenly distributed on the top of the receiving barrel 31. The bottom of the receiving barrel 31 is penetrated by a drainage groove 34. There are multiple groups of drainage grooves 34, which are evenly distributed on the bottom of the receiving barrel 31. The bottom end of the inner bottom of the receiving barrel 31 is rotatably connected to a guide column 1 36. The bottom end of the guide column 1 36 passes through the bottom end of the receiving barrel 31 and is fixedly connected to a guide column 2 37. The guide column 1 36 and the guide column 2 37 are both composed of a group of straight rods and two groups of guide strips symmetrically distributed on the outside of the straight rods. The two groups of guide strips are spirally wound around the outside of the straight rods, and each group of guide strips on the guide column 1 36 is aligned with a group of guide strips on the guide column 2 37. The guide bars are on the same spiral track, and the side ends of the guide posts 36 are fixedly connected with the blocking plates 35, and the bottom ends of the blocking plates 35 abut against the bottom ends of the inner parts of the receiving barrels 31. The number of blocking plates 35 is the same as the number of the drainage grooves 34, and the cross-section of the blocking plates 35 is triangular. The bottom width of the blocking plates 35 is greater than the width of the drainage grooves 34. The inner wall of the water inlet bucket 2 is fixedly connected with the guide cylinder 1 38, and the guide cylinder 1 38 is adapted to the guide post 1 36. The inner wall of the water inlet bucket 2 is fixedly connected with the guide cylinder 2 39, and the guide cylinder 2 39 is adapted to the guide cylinder 2 37. The guide cylinder 1 38 and the guide cylinder 2 39 are composed of a group of straight cylinders and four groups of straight rods. The four groups of straight rods are symmetrically distributed on the straight cylinder and fixedly connected to the straight cylinder. The other ends of the straight rods are fixedly connected to the water inlet bucket 2. There are two groups of guide blocks, wherein when the guide column 2 37 is inserted into the straight cylinder in the guide cylinder 2 39, the guide bar abuts against the guide block, thereby driving the blocking plate 35 to rotate, so that the blocking plate 35 is misaligned with the drainage groove 34, and when the guide column 1 36 is inserted into the straight cylinder in the guide cylinder 1 38, the guide bar abuts against the guide block, thereby driving the blocking plate 35 to rotate in the opposite direction and reset, so that the blocking plate 35 blocks the drainage groove 34 again. The dosing device 3 also includes a medicine storage box 311 fixedly connected to the outside of the water inlet barrel 2. The medicine storage box 311 is filled with flocculant, which makes the fine particles suspended in the wastewater condense into larger flocs, which is convenient for removing most of the suspended solids and reducing the turbidity of the wastewater. There are multiple groups of medicine storage boxes 311, which are evenly distributed on the outside of the water inlet barrel 2. The side end of the water inlet bucket 2 is provided with a feed port 310, and the feed port 310 is provided with multiple groups, which are evenly distributed on the side end of the water inlet bucket 2, and each group of feed ports 310 is connected with a group of medicine storage boxes 311. The side end of each group of medicine storage boxes 311 is slidably connected with an upper partition 313, and the cross-section of the upper partition 313 is L-shaped. One end of the upper partition 313 passes through the medicine storage box 311 and is fixedly connected with a push-out plate 312. The push-out plate 312 is arranged in the medicine storage box 311 and is slidably connected with the feed port 310. The push-out plate 312 is U-shaped, and the U-shaped opening faces the feed port 310. The bottom end of the push-out plate 312 facing the feed port 310 is an arc surface. One end of the upper partition 313 is fixedly connected with a spring 2 314, and one end of the spring 2 314 is fixedly connected to the outside of the water inlet bucket 2.Each set of upper partitions 313 is provided with two sets of springs 2 314, and the two sets of springs 2 314 are symmetrically distributed at one end of the upper partition 313. The top of the receiving barrel 31 is fixedly connected to a reset column 32. There are multiple sets of reset columns 32, and each set of reset columns 32 is arranged on the inner side of a set of springs 1 33. A set of cavities 315 is opened inside each set of reset columns 32. The top of the cavity 315 is fixedly connected to a mounting block 316. The mounting block 316 is a cube. The four sides of each set of mounting blocks 316 are fixedly connected to a set of springs 317. One end of each set of springs 317 is fixedly connected to a plug column 318. The plug column One end of 318 passes through the cavity 315 and the reset column 32. The through end of the plug 318 is an arc surface. When waste water enters the water inlet bucket 2, it first falls into the receiving bucket 31. At this time, the blocking plate 35 completely closes the drainage groove 34, and the waste water gradually accumulates in the receiving bucket 31. As the water volume increases, the receiving bucket 31 presses the spring 1 33 downward due to gravity, and at the same time drives the guide column 2 37 to insert into the guide cylinder 2 39. The spiral guide block in the guide cylinder 2 39 engages with the spiral guide bar of the guide column 2 37, driving the guide column 1 36 to rotate, so that the triangular blocking plate 35 is misaligned with the drainage groove 34, and the waste water flows through the drainage groove 3 4 forms a vortex discharge. At the same time, the receiving barrel 31 moves downward, causing the plug 318 on the top of the reset column 32 to be forced to retract into the cavity 315, so that the reset column 32 is separated from the water inlet barrel 2. As the receiving barrel 31 moves downward, the feed port 310 is exposed, so that the spring 2 314 is no longer stressed and restores its original length to push the U-shaped push plate 312 to slide into the water inlet barrel 2, so that the flocculant in the U-shaped push plate 312 is quantitatively fed into the wastewater through the feed port 310. When the wastewater accumulated in the receiving barrel 31 is emptied, and because the blocking plate 35 is misaligned with the drainage groove 34, the receiving barrel 31 no longer accumulates wastewater, and the spring 1 33 is stressed. As the force decreases, the rebound drives the receiving barrel 31 upward, causing the guide column 1 36 to insert into the guide cylinder 1 38. Under the reverse action of the spiral guide block, the blocking plate 35 returns to its original position and closes the drainage groove 34. At this time, the arc surface of the push plate 312 abuts the upward-moving receiving barrel 31, causing it to retract into the medicine storage box 311 under the abutment action, thereby automatically replenishing the flocculant in the medicine storage box 311 into the U-shaped groove, completing a dosing cycle. During the upward movement, the insertion column 318 in the reset column 32 cooperates with the dynamic limiter at the top of the water inlet barrel 2 via the spring 3 317, ensuring that the receiving barrel 31 is quickly and stably reset after it is reset, realizing periodic and continuous dosing.

[0037] The above scheme is adopted: the lifting and lowering of the receiving barrel 31 is driven by the gravity of the wastewater, combined with the linkage design of the spiral guide column and the sealing plate 35, to realize the automatic opening and closing of the flocculant and the quantitative control, and the water flow changes can be accurately matched without external power. The modular design of multiple groups of medicine storage boxes 311 and the U-shaped push plate 312 can not only ensure the uniform dispersion of the medicine, but also prevent blockage through the arc push plate, ensuring continuous and stable dosing efficiency. The vortex formed when the triangular sealing plate 35 and the drainage groove 34 are misaligned enhances the mixing effect of the flocculant and the wastewater, and promotes the rapid coagulation of suspended particles into flocs. In addition, the synergistic effect of the spring 1 33 and the reset column 32 makes the device self-recovering, and the elastic limit mechanism of the plug column 318 further improves the operational stability.

[0038] Reference Figures 7 and 8The filter device 4 includes a filter plate 41 fixedly connected to the inner wall of the water inlet bucket 2. The filter plate 41 is conical. The top of the filter plate 41 is fixedly connected to a connecting column 42. The outer side of the connecting column 42 is rotatably connected to a sleeve 43. The outer side of the sleeve 43 is fixedly connected to a fan blade 44. The fan blade 44 is provided with multiple groups, evenly distributed on the outer side of the sleeve 43, and the fan blade 44 is spiral. The bottom end of the fan blade 44 is in contact with the top of the filter plate 41, and the side end of the fan blade 44 is in contact with the inner wall of the water inlet bucket 2. A slag discharge groove 45 is provided through the inner wall of the water inlet bucket 2. The slag discharge groove 45 is provided with Multiple groups are evenly distributed on the inner wall of the water inlet barrel 2, and the slag trough 45 is arranged above the filter plate 41, and the bottom end of the inner side of the slag trough 45 is at the same horizontal plane as the lowest point of the top surface of the conical filter plate 41. A collecting plate 46 is fixedly connected to the outside of the water inlet barrel 2, and the inner side of the collecting plate 46 is connected to the slag trough 45. The collecting plate 46 is annular, and the cross section of the collecting plate 46 is J-shaped. An extrusion plate 47 is fixedly connected to the outside of the water inlet barrel 2, and the extrusion plate 47 is arranged above the collecting plate 46. The extrusion plate 47 is annular, and the cross section of the extrusion plate 47 is C-shaped. The collecting plate 46 The outside is fixedly connected with a guide plate 48, and the guide plate 48 is located below the extrusion plate 47. The guide plate 48 consists of a group of annular receiving plates and a group of discharge plates, and the outside of the receiving plate and the discharge plate is provided with an increased side plate, wherein the annular receiving plate is in an inclined state, and the connection between the discharge plate and the receiving plate is the lowest position of the receiving plate in the inclined state. After the wastewater is mixed with the dosing, it flows into the conical filter plate 41, and the water flow from top to bottom impacts the spiral blades 44, driving the sleeve 43 to rotate around the connecting column 42. The spiral structure of the blades 44 is in close contact with the surface of the filter plate 41 and The inner wall of the water inlet barrel 2 continuously pushes the retained impurities along the conical inclined surface of the filter plate 41 to the slag discharge groove 45, and the impurities fall into the annular J-shaped collecting plate 46 through the slag discharge groove 45. As the accumulation amount increases, the top impurities contact the arc-shaped inner wall of the C-shaped extrusion plate 47, and are squeezed and dehydrated in the annular space. The water flows back to the water inlet barrel 2 through the inclined surface of the bottom end of the collecting plate 46. The dehydrated solid impurities slide along the arc surface of the extrusion plate 47 to the outer guide plate 48. The inclined material receiving plate and the increased side plate of the guide plate 48 guide the impurities to the external collection container to achieve continuous slag discharge.

[0039] The above scheme is adopted: through the rotation of the spiral fan blades 44 and the inclined surface of the conical filter plate 41, automatic scraping and directional discharge of impurities are achieved, which significantly reduces the frequency of manual cleaning. The synergistic effect of the J-type collecting plate 46 and the C-type extrusion plate 47 completes extrusion dehydration when impurities accumulate, effectively separates the solid and liquid components, and reduces the subsequent processing load. The inclined design of the guide plate 48 combined with the increased side plate ensures the efficient discharge of impurities after dehydration and avoids secondary pollution. The dynamic cleaning function of the fan blades 44 can prevent the filter holes from being blocked and maintain a stable filtration flux. The overall structure is compact and is driven by the kinetic energy of water without the need for additional power.

The water enters the guide cylinder 55 and is guided to the outlet pipe 56 through the conical bottom end for discharge. When the adsorbent is saturated and needs to be replaced, the hydraulic rod 510 is started to pull down the filter cartridge 51, driving the insertion rod 58 to be inserted into the insertion tube 52. At this time, the spiral steering guide block 2 59 on the outside of the insertion rod 58 engages with the spiral steering guide block 1 53 on the inner wall of the insertion tube 52, driving the filter cartridge 51 to rotate 180 degrees. During the rotation, the T-shaped rotating block 511 slides along the annular groove at the bottom end of the filter cartridge 51, so that the saturated filter box 54 is rotated out of the working position under the water inlet bucket 2, and the unused filter box 54 is synchronously rotated into the processing position, realizing uninterrupted switching of the adsorbent. The saturated filter box 54 after replacement can be disassembled and cleaned separately or replaced with activated carbon to ensure continuous and efficient secondary filtration.

[0041] The above solution is adopted: through the mechanical linkage of hydraulic drive and spiral guide block, rapid rotation switching of adsorbent is achieved, and the filter box 54 can be replaced without stopping, which significantly improves the processing efficiency. The modular design of multiple sets of fan-shaped filter boxes 54 not only ensures sufficient contact between the adsorbent and wastewater, but also facilitates independent maintenance and reduces operating costs. The conical structure of the guide tube 55 optimizes the water flow distribution, and cooperates with the uniform drainage holes at the bottom end of the filter tube 51 to ensure that the wastewater passes through the activated carbon layer evenly, thereby improving the adsorption effect. The sliding cooperation between the T-shaped rotating block 511 and the annular groove enhances the rotation stability and avoids jamming.

[0042] The working principle of the present invention is as follows: when wastewater enters the water inlet barrel 2, the wastewater first falls into the receiving barrel 31. At this time, the drainage groove 34 of the blocking plate 35 is blocked, so that the wastewater accumulates in the receiving barrel 31. As the wastewater continues to enter the receiving barrel 31, the gravity acting on the spring 1 33 increases, thereby causing the spring 1 33 to stretch, and the receiving barrel 31 moves downward, and the abutment force between the plug post 318 and the top of the water inlet barrel 2 increases, thereby causing the plug post 318 to retract into the cavity 315, and causing the spring 317 to contract under force until the reset post 32 is separated from the top of the water inlet barrel 2. At this time, the spring 317 recovers its original length and pushes the plug post 318 to reset. During the movement, the feed port 310 is exposed. At this time, the receiving barrel 31 no longer abuts against the push-out plate 312, causing the spring 2 After the hopper 31 is fully opened, the hopper 31 is back to the original state, and the hopper 31 is in the closed state, so that the hopper 31 is in the closed state. After the hopper 31 is fully opened, the hopper 31 is in the closed state, and the hopper 31 is in the closed state. After the hopper 31 is fully opened, the hopper 31 is in the closed state, and the hopper 31 is in the closed state. After the upper partition 313 is removed from the medicine storage box 311, the flocculant in the medicine storage box 311 is stretched and the upper partition 313 is removed from the medicine storage box 311, so that the spring 2 314 is stretched. At this time, due to the movement of the upper partition 313, the flocculant in the medicine storage box 311 is no longer blocked by the upper partition 313 and slides down to the inner side of the U-shaped push plate 312. As the upward movement continues, When the guide post 36 is inserted into the guide cylinder 38, the spiral guide strip in the guide post 36 abuts against the guide block inside the guide cylinder 38, driving the guide post 36 to rotate in the opposite direction, so that the blocking plate 35 blocks the drainage groove 34 again. When the guide post 36 is fully inserted into the guide cylinder 38, the reset post 32 penetrates the top of the water inlet bucket 2. During the penetration process, the abutment force between the plug post 318 and the top of the water inlet bucket 2 increases, thereby retracting the plug post 318 into the cavity 315 and causing the spring 317 to be forced to contract until the plug post 318 moves to the top of the water inlet bucket 2. At this time, the spring 317 recovers its original length and pushes the plug post 318 to reset, so that the plug post 318 limits the receiving bucket 31, so that the receiving bucket 31 is reset under the action of the spring 33.Quickly restore to a stable state, and carry out the next round of accumulation operation. The wastewater discharged from the receiving barrel 31 flows to the conical filter plate 41, and the water flow from top to bottom impacts the fan blades 44, driving the sleeve 43 to rotate around the connecting column 42. The spiral fan blades 44 push the impurities trapped on the surface of the filter plate 41 along the inclined surface to the slag discharge groove 45. The impurities fall into the annular collecting plate 46 through the slag discharge groove 45. As the impurities accumulate, the top impurities contact the arc-shaped inner wall of the extrusion plate 47 and are squeezed and dehydrated in the annular space. The water flows back to the water inlet barrel 2 through the inclined surface of the bottom end of the collecting plate 46. The dehydrated solid impurities fall along the arc surface of the extrusion plate 47 to the outer guide plate 48 and are guided to the external collection container by the inclined guide plate 48 to achieve solid-liquid separation and continuous slag discharge. The wastewater after the initial filtration passes through the inlet The water flows into the filter cartridge 51 through the drainage hole at the bottom of the water bucket 2 and flows evenly into the fan-shaped filter box 54 filled with activated carbon. After absorbing the residual impurities, the water flows into the guide tube 55 through the drainage hole at the bottom of the filter cartridge 51 and is discharged to the outlet pipe 56 under the guidance of the conical surface at the bottom of the guide tube 55. When the adsorbent is saturated and needs to be replaced, the hydraulic rod 510 is activated to pull down the filter cartridge 51 so that the insertion rod 58 is inserted into the insertion tube 52. Under the abutment of the spiral steering guide block 2 59 and the steering guide block 1 53, the filter cartridge 51 is driven to rotate 180 degrees, so that the saturated filter box 54 originally located under the water inlet bucket 2 is rotated to the outside, and the unused filter box 54 is synchronously rotated into the working position, realizing the uninterrupted switching of the adsorbent. The saturated filter box 54 after replacement can be disassembled for cleaning or replaced. Carbon, to ensure the secondary adsorption filtration efficiency; through the dosing device 3, the wastewater gravity is used to drive the receiving barrel 31 to rise and fall, and the spiral guide column and the blocking plate 35 are combined to realize the automatic opening and closing of the flocculant and the quantitative control. Multiple groups of medicine storage boxes 311 are matched with the U-shaped push-out plate 312 to ensure that the medicine is evenly dispersed and prevent blockage. The vortex formed by the triangular blocking plate 35 strengthens the mixing effect of the flocculant and the wastewater, and promotes the rapid coagulation of suspended particles. The limiting mechanism of the spring and the plug 318 improves the operation stability. The device does not require external power and can accurately match the water flow changes to achieve continuous, stable and efficient dosing, significantly reducing manual intervention and operating costs. Through the filtering device 1 4, the spiral fan blades 44 cooperate with the inclined surface of the conical filter plate 41 to use the kinetic energy of water to drive The fan blades 44 rotate, automatically scraping off impurities on the surface of the filter plate 41 and pushing them to the slag discharge trough 45, and the filter surface can be cleaned without additional power. The J-shaped collecting plate 46 and the C-shaped extrusion plate 47 cooperate to realize impurity extrusion and dehydration. The separated water flows back to the water inlet bucket 2, and the solid impurities are discharged through the guide plate 48, which reduces the subsequent processing load, reduces the frequency of manual cleaning, prevents the filter holes from being blocked, and maintains a stable filtration flux. The structure is compact and the energy consumption is low, which effectively improves the efficiency and continuity of solid-liquid separation. Through the mechanical linkage of the filter device 2 5, the hydraulic rod 510 and the spiral guide block realize the uninterrupted rotation switching of the adsorbent. The saturated filter box 54 can be removed and the unused filter box 54 can be transferred to the working position without stopping the machine. The modular design of multiple sets of fan-shaped filter boxes 54 is convenient for independent maintenance.The conical structure of the guide tube 55 optimizes water flow distribution, ensuring that wastewater flows evenly through the activated carbon layer, enhancing adsorption efficiency. The T-shaped rotating block 511 cooperates with the annular groove to enhance rotational stability and prevent jamming. This device significantly improves treatment efficiency, reduces replacement costs, and ensures continued high efficiency and convenient maintenance of secondary filtration.
