Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a comprehensive treatment device for wastewater from the recycling of cobalt and nickel waste from the industry. Background Technology

[0002] With the rapid development of strategic industries such as new energy batteries and high-temperature alloys, the demand for rare metals such as cobalt and nickel continues to rise. The recycling of cobalt and nickel waste generates large amounts of industrial wastewater containing cobalt and nickel ions. Direct discharge of this wastewater not only causes environmental pollution but also leads to the loss of valuable metal resources. Currently, chemical precipitation is the mainstream process for treating this type of wastewater—by adjusting the pH value and adding a precipitant, dissolved Co... 2+ Ni 2+ The precipitate is converted into an insoluble hydroxide precipitate, and then metal recovery and wastewater purification are achieved through solid-liquid separation. In order to improve the solid-liquid separation efficiency of fine precipitates, flocculants are usually added after the precipitation reaction in engineering practice to make the fine particles aggregate into large flocs.

[0003] However, existing solid-liquid separation equipment still has the following technical defects: flocculants are directly added to wastewater, requiring large quantities and making it difficult to precisely control reaction conditions; the flocs are unevenly distributed in the flow channel, leading to rapid local clogging of the filter media; after the filter media is clogged, the process is usually interrupted by backwashing or replacing the filter screen, which has limited effectiveness in removing fine particles stuck deep in the mesh; and the cobalt and nickel precipitates shaken off during the cleaning process lack an immediate collection device, which can easily cause secondary pollution and resource loss. Therefore, a treatment device is needed that can achieve online, efficient, and adaptive cleaning, and can simultaneously complete precision filtration and resource recovery.

A transmission gear is fixedly connected to the rear side of the connecting shaft. The transmission gear meshes with a fixed rack. A drive sprocket is fixedly connected to the front side of the connecting shaft.

[0008] Preferably, the vibration mechanism includes a water tank, a striking protrusion, a transmission sprocket, and two sets of multi-peak cams. The water tank is placed on the right side of the waste collection box. The protrusion of the multi-peak cams gradually increases from small to large. Two sets of limiting plates are fixedly connected to the lower inner surface of the workbench. A fixed shaft is rotatably connected between the two sets of limiting plates. The transmission sprocket is fixedly connected to the front side of the fixed shaft. The two sets of multi-peak cams are respectively fixedly connected to the front and rear sides of the fixed shaft. The drive sprocket is connected to the transmission sprocket via a chain. A guide shaft slides through the middle of the striking protrusion. A drive plate is fixedly connected to the front and rear sides of the guide shaft. Limit blocks are fixedly connected to the front and rear sides of the left end of the filter box. The drive plate slides through the inside of the limit blocks. A roller is rotatably connected to the lower end of the drive plate. A mating rod is provided between the front and rear rollers. The roller slides on the surface of the multi-peak cam.

[0009] Preferably, a limiting shaft is fixedly connected to the lower side of the guide shaft between the front and rear drive plates. Several return springs are fixedly connected between the limiting shaft and the striking protrusion. The interior of the striking protrusion is hollow. Several one-way holes are fixedly opened on the upper surface of the striking protrusion. A nozzle is provided on the upper side of the water tank. The output end of the nozzle is connected to the striking protrusion through several sets of hoses. The striking protrusion is located on the right side of the brush wheel.

[0010] Preferably, the suction mechanism includes a suction hood and a vacuum pump. The vacuum pump is located at the upper end of the workbench, and a collection sleeve is provided at the output end of the vacuum pump. The collection sleeve is connected to the suction hood. A vibration sensor is provided in the middle of the suction hood, and the lower end of the suction hood is tilted at the same angle as the filter plate.

[0011] Preferably, a liquid storage tank is also provided on the upper side of the workbench. The liquid storage tank is connected to the spraying part through a connecting pipe, and the inclination of the spraying part is consistent with the inclination of the filter plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention cleans the filter plate by setting up a cleaning mechanism. When the filter plate is pulled out, the brush wheel rotates to clean the filter plate. The counterclockwise rotation causes the bristles to embed into the mesh, thereby effectively scraping and hooking out stubborn particles stuck in the holes. When the filter plate returns to the filter box, the brush wheel rotates clockwise to evenly coat the flocculant on the surface of the filter plate, improving the filtration effect of the filter plate on wastewater when it returns to the filter box, thus achieving continuous and efficient filtration.

[0014] This invention uses a vibration mechanism to vibrate the filter plate. The vibration intensity is changed by adjusting the protrusion of the multi-peak cam surface protrusions. When the filter plate is pulled out, the vibration intensity of the vibration mechanism gradually increases, thereby achieving powerful cleaning of the filter material that accumulates on the filter plate. When the protrusions move upward, they come into contact with the brush wheel, further increasing the depth of the brush wheel's embedding into the mesh and the cleaning power. Water sprayed through the one-way hole also concentrates on rinsing the mesh and the connection between the brush, further improving the cleaning effect on the filter plate.

[0015] When the filter plate returns to the filter box, the vibration intensity of the vibration mechanism gradually decreases from strong to weak. Initially, it disperses the sprayed flocculant droplets to prevent them from sticking together. Then, by reducing the vibration intensity, the flocculant gradually penetrates into the mesh and forms a uniform and stable film under the coating of the brush wheel, further improving the filtration effect on wastewater. This achieves efficient interception of fine precipitates in cobalt and nickel wastewater and recovery of metal resources. Attached Figure Description

[0020] Furthermore, the vibration mechanism 300 includes a water tank 301, striking protrusions 303, a transmission sprocket 306, and two sets of multi-peak cams 307. The water tank 301 is placed on the right side of the waste collection box 6. The protrusions of the multi-peak cams 307 gradually increase in size. Two sets of limiting plates 304 are fixedly connected to the lower inner surface of the worktable 2. A fixed shaft 305 is rotatably connected between the two sets of limiting plates 304. The transmission sprocket 306 is fixedly connected to the front side of the fixed shaft 305. The two sets of multi-peak cams 307 are respectively fixedly connected to the fixed shaft 305.

The roller 308 slides on the surface of the multi-peak cam 307.

[0021] Furthermore, a limiting shaft 312 is fixedly connected between the lower side of the guide shaft 311 and the front and rear drive plates 310. Several return springs 314 are fixedly connected between the limiting shaft 312 and the striking protrusion 303. The interior of the striking protrusion 303 is hollow. Several one-way holes 313 are fixedly opened on the upper surface of the striking protrusion 303. A nozzle 302 is provided on the upper side of the water tank 301. The output end of the nozzle 302 is connected to the striking protrusion 303 through several sets of hoses. The striking protrusion 303 is located on the right side of the brush wheel 201.

[0022] Furthermore, the suction mechanism 400 includes a suction hood 401 and a vacuum pump 404. The vacuum pump 404 is located at the upper end of the workbench 2. A collection sleeve 402 is provided at the output end of the vacuum pump 404. The collection sleeve 402 is connected to the suction hood 401. A vibration sensor 403 is provided in the middle of the suction hood 401. The lower end of the suction hood 401 is tilted at the same angle as the filter plate 103.

[0023] Furthermore, a liquid storage tank 7 is also provided on the upper side of the workbench 2. The liquid storage tank 7 is connected to the spraying section 8 through a connecting pipe. The inclination of the spraying section 8 is consistent with the inclination of the filter plate 103.

[0024] Furthermore, such as Figure 1 Several sets of support legs 5 are fixedly connected to the lower side of both the filter box 1 and the workbench 2. The tail end of the filter box 1 is connected to the reactor 4 through the conveying pipe 3. To further improve the cleaning effect on the filter plate 103, the center of gravity of the tapping protrusion 303 is shifted to the left, and the bristles of the brush wheel 201 are tilted clockwise.

[0025] Working principle: After chemical precipitation treatment, the cobalt and nickel wastewater enters the filter box 1. The filter plate 103 intercepts the cobalt and nickel precipitates in the wastewater to achieve solid-liquid separation. The intercepted precipitates are enriched with valuable metals such as cobalt and nickel, which can be recycled as resources. The filtered clear liquid enters the reaction vessel 4 through the conveying pipe 3 to complete the collection. When the filter plate 103 needs to be cleaned, the output end of the cylinder 101 drives the telescopic rod 102 fixedly connected to it to move to the left. The telescopic rod 102 pulls the filter plate 103 to move to the left. At the same time as the filter plate 103 moves to the left, the fixed rack 105 meshes with the transmission gear 204. The transmission gear 204 is driven by force to rotate the connecting shaft 202 fixedly connected to it counterclockwise. The connecting shaft 202 drives the brush wheel 201 fixedly connected to it and the drive sprocket 205 to rotate counterclockwise. At the same time as the brush wheel 201 rotates, it cleans the moving filter plate 103. The drive sprocket 205 drives the transmission sprocket 306 to rotate counterclockwise via a chain. The rotation period of the transmission sprocket 306 is changed by adjusting the transmission ratio. When the fixed rack 105 engages with the transmission gear 204, the transmission sprocket 306 completes a full rotation. The transmission sprocket 306 drives the fixed shaft 305, which is fixedly connected to it, to rotate. The fixed shaft 305 drives the multi-peak cam 307, which is fixedly connected to it, to rotate. When the multi-peak cam 307 rotates, the limit block 315 vertically limits the drive plate 310. The roller 308, which moves on the surface of the multi-peak cam 307, reciprocates up and down under the setting of the protrusion. The roller 308 drives the striking protrusion 303 to move up and down via the drive plate 310. When the striking protrusion 303 moves up and down, it will impact the moving filter plate. The brush wheel 201 performs a knocking and impacting action to improve the cleaning performance of the filter plate 103. Since the size of the protrusions on the surface of the multi-peak cam 307 gradually increases from small to large, the impact force of the drive plate 310 on the filter plate 103 will also increase from weak to strong when the multi-peak cam 307 rotates counterclockwise. When the filter plate 103 is just pulled out, the knocking protrusions 303 impact the filter plate 103 with the greatest impact. At this time, the part of the filter plate 103 that is pulled out is the part that comes into contact with the wastewater first, and it traps larger particles with relatively weak adhesion. At this time, only a gentle vibration is needed to shake them off. As the filter plate 103 is gradually pulled out, the cleaning area gradually shifts to the most serious area. At this time, the cleaning force gradually increases, thereby removing the most stubborn pollutant deposits. Furthermore, since the center of gravity of the striking protrusion 303 is biased to the left, when the striking protrusion 303 strikes the filter plate 103, the surface of the striking protrusion 303 rotates to the left around the guide shaft 311 under pressure. When the striking protrusion 303 moves downward, it will be pulled back to its original position under the elastic force of the return spring 314. During the movement to the right, it will perform a second aftershock on the filter plate 103, further loosening the filtered material. Since the direction of the brush wheel 201 is clockwise, when it rotates counterclockwise, the bristles on its surface will be in a counter-clockwise state. When the brush wheel 201 comes into contact with the filter plate 103, the bristles on its surface will insert into the mesh for cleaning. When the tapping protrusion 303 moves to the upper side, it will squeeze the bristles on the right side of the brush wheel 201. In this process, the cleaning power of the brush wheel 201 on the mesh blockage will be further improved. During this cleaning process, as the upward force of the tapping protrusion 303 gradually increases, the cleaning power of the bristles on the mesh will also gradually increase. Water tank 301 supplies water to striking protrusion 303 through nozzle 302. Striking protrusion 303 sprays water to filter plate 103 for concentrated cleaning through one-way hole 313. High-pressure water flow washes the mesh of filter plate 103 through one-way hole 313. Striking protrusion 303 also moves up and down. When it moves upward and comes into contact with filter plate 103, the one-way hole 313 is closest to the mesh, which can perform efficient cleaning of the mesh. Part of the water flow washes brush wheel 201 through one-way hole 313 on the left side, further improving the cleaning effect of the bristles of brush wheel 201 on filter plate 103. During the process of extracting the filter plate 103, whenever the vibration mechanism 300 strikes the filter plate 103, the suction hood 401 attached to the upper surface of the filter plate 103 will also be vibrated. The vibration sensor 403 detects the vibration signal generated by the impact and then controls the vacuum pump 404 to work, so that the suction hood 401 can collect the shaken cobalt nickel precipitate. Under the synergistic action of the bristles embedded in the brush wheel 201 and the striking protrusions 303, the filter material moving into the air will be collected in time, further improving the cleaning effect of the precipitate and the metal resource recovery rate. When the filter plate 103 is completely pulled out, the cleaning of the filtered material is completed. The water spraying operation of the water tank 301 is turned off. Then, the cylinder 101 controls the filter plate 103 to return to the interior of the filter box 1. The liquid storage tank 7 controls the spraying unit 8 to spray flocculant onto the filter plate 103. At this time, the fixed rack 105 controls the transmission gear 204 to rotate clockwise, and the brush wheel 201 and the transmission sprocket 306 rotate clockwise. When the brush wheel 201 rotates clockwise, since it is along the direction of the bristles, most of the bristles will adhere to the lower surface of the filter plate 103, thereby coating the flocculant on the surface of the filter plate 103. When the multi-peak cam 307 rotates clockwise, it taps the protrusion 303. The tapping force gradually decreases from strong to weak. At the very beginning of spraying, strong vibration can break up the flocculant and prevent the droplets from sticking together. At the same time, the vibration force throws the flocculant across the entire filter plate 103. As the filter plate 103 is gradually pushed back in, the vibration amplitude also decreases. At this time, the vibration is to allow the flocculant molecules to penetrate deep into the mesh, thereby forming a stable and uniform flocculant film. When the filter plate 103 returns to the filter box 1, the flocculant film comes into contact with the cobalt-nickel wastewater entering the filter box 1. The fine precipitate particles in the wastewater react instantly with the flocculant when passing through the filter plate 103, quickly flocculating into large flocs, which are efficiently intercepted by the filter plate, thereby achieving continuous and efficient filtration and resource recovery.
