Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a harmless treatment device for wastewater prepared by ore dressing reagents. Background Art

[0002] In order to change the hydrophobicity of minerals and facilitate mineral stratification during mineral processing, a large amount of flotation agents are added to the mineral processing water. The wastewater generated after the mineral processing is completed contains a large amount of metal ions. The residual metal ions in the wastewater will combine with the flotation agents to form precipitation. This part of the precipitation contains a large amount of heavy metal ions and needs to be harmlessly treated to prevent pollution to the environment when it is directly discharged.

[0003] The Chinese patent with the patent announcement number CN113461229B discloses a treatment device for wastewater produced by mineral processing reagents, which belongs to the technical field of treatment devices for wastewater produced by mineral processing reagents. It includes a wastewater purification box, a drainage port is provided at the lower part of the right surface of the wastewater purification box, a sewage pipe is fixedly connected to the upper part of the wastewater purification box, a sewage inlet box is fixedly connected to the top of the inner surface of the wastewater purification box, a rotating rod 2 is provided on the inner surface of the left part of the sewage inlet box, and a transmission crawler is movably connected to the outer surface of the right part of the rotating rod 2. The patent moves two rectangular rods one upward in two slide grooves one, and the L-shaped baffle moves upward to pull and deform the elastic rod. When the water volume increases to a certain height, the floating block will also move upward to a certain height synchronously. At this time, the drainage port is opened a little distance, and the purified water is discharged from the drainage port. When a certain amount of water is discharged, the floating block moves downward again to close the drainage port, which is conducive to maintaining the water level in the wastewater purification box and preventing the purification effect from being reduced due to excessive wastewater.

[0004] However, the current wastewater harmless treatment device has the following problems: when treating wastewater, the wastewater harmless treatment device is not convenient to treat the wastewater scum following the liquid surface of the wastewater, and the scum is not removed in time following the changes in the liquid surface, which easily leads to the accumulation of scum in the wastewater, affecting the wastewater treatment effect and even causing secondary pollution. Therefore, we propose a harmless treatment device for wastewater prepared by mineral processing agents. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a device for harmless treatment of wastewater from the preparation of mineral processing reagents, which solves the problems raised in the above-mentioned background technology.

It is worth noting that most of the flocs generated by the reaction of the wastewater and the water treatment agent will be intercepted by the interception net, and a small amount of flocs will pass through the interception net.

[0007] According to the above technical solution, the delivery device also includes a swing plate, two circular frames, and two L-shaped columns. The swing plate is hinged at the lower outer wall of the semicircular shell, and the two circular frames are respectively fixed on both sides of the top of the swing plate. One end of the two L-shaped columns is respectively slidably installed on the inner wall of the semicircular shell, and the other end of the two L-shaped columns is respectively slidably installed inside the two circular frames. A number of semicircular blocks are evenly and equidistantly fixed on the outer walls of both sides of the hollow tube, and the horizontal support rods of the L-shaped columns are located at the movement of the semicircular blocks of the hollow tube.

The swing plate periodically guides the water flow to impact the C-shaped channel between the semicircular shell and the arc shell, thereby changing the flow path of the mixed wastewater and water treatment agent.

[0008] According to the above technical scheme, a scum removal device is provided on the rear side of the interior of the processing chamber, and the scum removal device includes a pulley 1, a reciprocating screw, a pump 2, and a float.

The pump 2 is fixed to the top of the collection chamber through a bracket, and an L-shaped folded tube is fixed at the water inlet end of the pump 2, and the end of the L-shaped folded tube away from the pump 2 is fixed on the top of the cross frame. A U-shaped slide plate is slidably installed inside the collection box, and one end of the U-shaped slide plate slides The U-shaped slide is dynamically installed on the outer wall of the movable plate, and a scraper is fixed on the other end of the U-shaped slide, and the scraper is located between the two side boxes. As the wastewater level inside the treatment chamber rises, the float will float on the wastewater liquid surface due to the buoyancy, and the float drives the collecting box and the side box to float on the wastewater liquid surface. At the same time, the collecting box drives the U-shaped slide to slide upward along the outside of the movable plate, and when the hollow tube rotates, it drives pulley one to rotate. Under the belt transmission, pulley one drives pulley two to rotate through the belt, and pulley two drives the reciprocating screw rod to rotate, and the reciprocating screw rod drives the movable plate to move back and forth, and the movable plate drives the U-shaped slide to reciprocate along the inside of the collecting box. When the U-shaped slide moves, it drives the scraper to move back and forth between the two side boxes, and the scraper will scrape the scum on the surface of the wastewater into the side box, and the side box will drain the scum into the collecting box, and then start the second pump, and the second pump draws the scum in the collecting box into the collecting chamber through the L-shaped folded tube for collection.

[0009] According to the above technical solution, the scum removal device also includes a friction wheel, a friction plate, and a rotating rod. The rotating rod is rotatably installed at the bottom of the scraper, and a plurality of flipping leaves are evenly fixed on the outer circumference of the rotating rod. The friction wheel is fixed on the side of the rotating rod close to the collecting box, and the friction plate is fixed on the outer wall of the collecting box. The outer part of the friction wheel is set as a rough surface, and the top of the friction plate is set as a rough surface. The outer part of the friction wheel contacts the top of the friction plate. During the reciprocating movement of the scraper, the scraper drives the friction wheel to move with it through the rotating rod. Under the action of the friction force between the friction wheel and the friction plate, the friction plate drives the friction wheel to rotate, the friction wheel drives the rotating rod to rotate, and the rotating rod drives the flipping leaves to stir the wastewater below the scum.

[0010] The scum removal device also includes a U-shaped lifting plate, a resistance rod, and two elastic telescopic rods. The fixed ends of the two elastic telescopic rods are respectively fixed to the two sides of the bottom of the inner wall of the collecting box.

[0011] The present invention provides a device for harmless treatment of wastewater from the preparation of mineral processing reagents. It has the following beneficial effects: (1) The present invention arranges a delivery device so that the water treatment agent is mixed with the wastewater entering the semicircular shell, thereby ensuring that the water treatment agent contacts the wastewater more evenly and promoting the reaction between the agent and the pollutants in the wastewater. The hollow tube drives the spray nozzle to rotate, so that the water treatment agent can be evenly sprayed into the wastewater, ensuring that the water treatment agent is more evenly distributed in the wastewater, which helps to improve the contact rate and reaction efficiency between the agent and the pollutants in the wastewater. At the same time, the structure of the C-shaped channel between the semicircular shell and the arc shell further increases the contact area between the wastewater and the water treatment agent. When the wastewater flows through the C-shaped channel, the flow rate and flow direction of the wastewater change due to the tortuosity of the C-shaped channel, thereby enhancing the The mixing effect of wastewater and water treatment agent helps the agent to fully react during the entire wastewater flow process and improves the efficiency of removing pollutants. At the same time, the hollow tube, L-shaped column, semicircular shell, and circular frame cooperate to drive the swing plate to periodically guide the water flow to impact the semicircular shell and the arc shell to form a C-shaped channel, thereby changing the flow path of the mixed wastewater and water treatment agent and generating a certain vortex effect, causing the water flow to repeatedly collide and rotate in the C-shaped channel. This rotating flow further increases the contact time and contact area between the water flow and the water treatment agent, promotes the uniform distribution of the water treatment agent, and enhances the contact and reaction effect between the water treatment agent and the pollutants in the wastewater, thereby improving the treatment effect.

[0012] (2) The present invention arranges a scum removal device so that the scraper moves back and forth between the two side boxes. The scraper scrapes the scum on the surface of the wastewater into the side boxes. The side boxes drain the scum into the collection box, and the pump 2 draws the scum in the collection box into the collection chamber through the L-shaped folded tube for collection. By processing the scum on the surface of the wastewater, the accumulation of pollutants on the surface of the wastewater is reduced, thereby keeping the wastewater clean.

[0013] (3) The present invention uses a scraper, a rotating rod, a friction wheel, and a friction plate to drive the turning blades to stir the wastewater below the scum. The turning blades can effectively break the adhesion between the scum and the wastewater by stirring the wastewater below the scum, making it easier for the scum to be scraped into the side box by the scraper; at the same time, the U-shaped slide plate, the resistance rod, the U-shaped lifting plate, and the elastic telescopic rod cooperate to drive the U-shaped lifting plate to move up and down, thereby promoting the efficiency of the scum in the side box flowing into the collection box.

Through the arrangement of the above structure, the water treatment agent is mixed with the wastewater entering the semicircular shell 34, thereby ensuring that the water treatment agent contacts the wastewater more evenly, and promoting the reaction between the agent and the pollutants in the wastewater In this process, the motor drives the hollow tube 36 to rotate the spray nozzle 37, so that the water treatment agent can be evenly sprayed into the wastewater, ensuring that the water treatment agent is more evenly distributed in the wastewater, which helps to improve the contact rate and reaction efficiency between the agent and the pollutants in the wastewater.

This rotating flow further increases the contact time and contact area between the water flow and the water treatment agent, promotes the uniform distribution of the water treatment agent, enhances the contact and reaction effect between the water treatment agent and the pollutants in the wastewater, and thus improves the treatment effect.

[0019] A scum removal device 4 is provided at the rear side of the interior of the processing chamber 11, and the scum removal device 4 includes a pulley 41, a reciprocating screw 43, a pump 45, and a float 410. The pulley 41 is fixed to the outside of the hollow tube 36, and the reciprocating screw 43 is rotatably installed at the rear side of the interior of the processing chamber 11. A pulley 42 is fixed to the side of the reciprocating screw 43, and the pulley 42 is connected to the pulley 41 by a belt transmission. The external thread of the reciprocating screw 43 is connected to a movable plate 44. The float 410 is arranged in the interior of the processing chamber 11. It should be noted that as the wastewater level in the processing chamber 11 rises, the float 410 will be affected by the buoyancy of the wastewater in the processing chamber 11, and the float 410 will float on the wastewater liquid surface. A collecting box 49 is fixed on the top of the float 410, and a cross frame 48 is fixed on the top of the collecting box 49. Both sides of the collecting box 49 close to the hollow tube 36 are fixed A side box 411 is fixed, and the second pump 45 is fixed to the top of the collection chamber 2 through a bracket. An L-shaped folded tube 46 is fixed to the water inlet end of the second pump 45. The end of the L-shaped folded tube 46 away from the second pump 45 is fixed to the top of the cross frame 48. A U-shaped slide plate 47 is slidably installed inside the collection box 49. One end of the U-shaped slide plate 47 is slidably installed on the outer wall of the movable plate 44. A scraper 412 is fixed to the other end of the U-shaped slide plate 47, and the scraper 412 is located between the two side boxes 411.

By treating the scum on the surface of the wastewater, the accumulation of pollutants on the surface of the wastewater is reduced, and the wastewater is kept clean.

[0020] The scum removal device 4 also includes a friction wheel 413, a friction plate 414, and a rotating rod 415. The rotating rod 415 is rotatably installed at the bottom of the scraper 412. A plurality of flipping leaves 416 are evenly fixed on the outer circumference of the rotating rod 415. The friction wheel 413 is fixed on one side of the rotating rod 415 close to the collecting box 49. The friction plate 414 is fixed on the outer wall of the collecting box 49. The outer surface of the friction wheel 413 is a rough surface. The top of the friction plate 414 is a rough surface. The outer surface of the friction wheel 413 is in contact with the top of the friction plate 414. Through the arrangement of the above structure, the rotating rod 415 drives the flipping leaves 416 to stir the wastewater under the scum. The flipping leaves 416 can effectively break the adhesion between the scum and the wastewater by stirring the wastewater under the scum, so that the scum can be more easily scraped into the side box 411 by the scraper 412.

[0021] The scum removing device 4 also includes a U-shaped lifting plate 417, a resistance rod 419, and two elastic telescopic rods 418. The fixed ends of the two elastic telescopic rods 418 are respectively fixed to the two sides of the bottom of the inner wall of the collecting box 49, and the U-shaped lifting plate 417 is fixed to the top of the telescopic end of the elastic telescopic rod 418.

The semicircular protrusions of the U-shaped lifting plate 417 are located on the semicircular movement trajectory of the resistance rod 419. Through the arrangement of the above structure, the U-shaped lifting plate 417 is shaken up and down, thereby promoting the efficiency of the scum in the side box 411 flowing into the collecting box 49.

[0022] When in use, the liquid inlet pipe 31 is connected to the external wastewater pipe, and the external wastewater pipe puts the wastewater into the treatment chamber 11 through the liquid inlet pipe 31. In this process, the wastewater will pass through the semicircular shell 34 and the arc shell 35. At the same time, the injection component 33 is started, and the pump 332 extracts the water treatment agent in the water treatment agent box 331 and transmits it to the joint 334 through the connecting pipe 333. The joint 334 transports the water treatment agent to the hollow pipe 36. The hollow pipe 36 transports the water treatment agent and sprays it into the semicircular shell 34 through the spray nozzle 37, so that the water treatment agent is mixed with the wastewater entering the semicircular shell 34, thereby ensuring that the water treatment agent is connected with the wastewater. The contact is more uniform, which promotes the reaction between the agent and the pollutants in the wastewater. In this process, the motor drives the hollow tube 36 to drive the spray nozzle 37 to rotate, so that the water treatment agent can be evenly sprayed into the wastewater, ensuring that the distribution of the water treatment agent in the wastewater is more uniform, which helps to improve the contact rate and reaction efficiency between the agent and the pollutants in the wastewater. At the same time, the structure of the C-shaped channel between the semicircular shell 34 and the arc shell 35 further increases the contact area between the wastewater and the water treatment agent. When the wastewater flows through the C-shaped channel, due to the tortuosity of the C-shaped channel, the flow rate and flow direction of the wastewater change, which enhances the contact between the wastewater and the water treatment agent. The mixing effect of the agent helps the agent to fully react during the entire wastewater flow process and improves the efficiency of removing pollutants. It is worth noting that most of the flocs generated by the reaction of wastewater and water treatment agents will be intercepted by the interception net 32, and a small amount of flocs will pass through the interception net 32; when the hollow tube 36 rotates, the hollow tube 36 will drive the semicircular blocks thereon to rotate, and the semicircular blocks of the hollow tube 36 will push the L-shaped column 310 to move upward along the inner wall of the semicircular shell 34, and the L-shaped column 310 slides along the inside of the circular frame 39, and the L-shaped column 310 drives the swing plate 38 to swing upward through the circular frame 39. When When the semicircular block of the hollow tube 36 does not push the L-shaped column rod 310, the swing plate 38 returns to its original position and swings downward, and so on. The swing plate 38 periodically guides the water flow to impact the C-shaped channel formed between the semicircular shell 34 and the arc shell 35, thereby changing the flow path of the mixed wastewater and water treatment agent and generating a certain vortex effect, causing the water flow to repeatedly collide and rotate in the C-shaped channel. This rotating flow further increases the contact time and contact area between the water flow and the water treatment agent, promotes the uniform distribution of the water treatment agent, and enhances the contact and reaction effect between the water treatment agent and the pollutants in the wastewater, thereby improving the treatment effect.

[0023] As the wastewater level inside the treatment chamber 11 rises, the float 410 is floated on the wastewater surface by the buoyancy, and the float 410 drives the collection box 49 and the side box 411 to float on the wastewater surface. At the same time, the collection box 49 drives the U-shaped slide plate 47 to slide upward along the outside of the moving plate 44. When the hollow tube 36 rotates, it drives the pulley 1 41 to rotate. Under the belt drive, the pulley 1 41 drives the pulley 2 42 to rotate through the belt, and the pulley 2 42 drives the reciprocating screw 43 to rotate. The reciprocating screw 43 drives the moving plate 44 to reciprocate, and the moving plate 44 drives the U-shaped slide plate 47 to slide upward along the outside of the moving plate 44. The U-shaped slide plate 47 moves back and forth along the inside of the collection box 49. When the U-shaped slide plate 47 moves, it will drive the scraper 412 to move back and forth between the two side boxes 411. The scraper 412 will scrape the scum on the surface of the wastewater into the side box 411, and the side box 411 will drain the scum into the collection box 49. Then, the pump 45 is started. The pump 45 draws the scum in the collection box 49 into the collection chamber 2 through the L-shaped folded tube 46 for collection. By processing the scum on the surface of the wastewater, the accumulation of pollutants on the surface of the wastewater is reduced, and the wastewater is kept clean. When the scraper 412 moves back and forth, During the process, the scraper 412 drives the friction wheel 413 to move through the rotating rod 415. Under the friction force between the friction wheel 413 and the friction plate 414, the friction plate 414 drives the friction wheel 413 to rotate, and the friction wheel 413 drives the rotating rod 415 to rotate. The rotating rod 415 drives the turning blade 416 to stir the wastewater under the scum. The turning blade 416 can effectively break the adhesion between the scum and the wastewater by stirring the wastewater under the scum, so that the scum is more easily scraped into the side box 411 by the scraper 412; at the same time, the U-shaped slide plate 47 will drive the friction wheel 413 to rotate during the reciprocating movement. The touch rod 419 moves, and the semicircular shape of the resistance rod 419 pushes the semicircular protrusion of the U-shaped lifting plate 417 to drive the U-shaped lifting plate 417 to move upward, and the U-shaped lifting plate 417 drives the telescopic end of the elastic telescopic rod 418 to stretch. When the semicircular shape of the resistance rod 419 no longer pushes the semicircular protrusion of the U-shaped lifting plate 417, under the elastic force of the elastic telescopic rod 418, the elastic telescopic rod 418 drives the U-shaped lifting plate 417 to reset and move downward, and so on and so forth, so that the U-shaped lifting plate 417 bounces up and down, thereby promoting the efficiency of the scum in the side box 411 flowing into the collection box 49.
