Description

Technical Field

[0001] The invention relates to the technical field of electroplating wastewater treatment, and in particular to wastewater treatment equipment for electroplating production. Background Art

[0002] Electroplating wastewater needs to undergo a crystallization separation step for further treatment and utilization. Crystallization separation is a commonly used water treatment technology that can effectively remove solid pollutants in electroplating wastewater, such as lead, zinc, iron, etc. If the electroplating wastewater contains a high concentration of a certain specific metal ion, such as precious metals (gold, silver, platinum, etc.), and its value is high, consider using crystallization method for recycling.

[0003] The wastewater generated by the existing electroplating wastewater treatment needs to be treated through processes such as sedimentation, crystallization, and separation. A centrifuge is required to separate the crystallized wastewater into solid and liquid. However, the crystals in the wastewater tend to aggregate in the micropores on the surface of the drum, causing clogging of the micropores, thereby affecting the efficiency of solid-liquid separation.

[0007] Furthermore, the solid-liquid separation component also includes a brush sleeve, and the outer wall of the transmission shaft is provided with a brush sleeve.

[0008] Furthermore, the solid-liquid separation component also includes a lower cone and water holes. The lower cone is fixed to the bottom of the disc, and the water holes are evenly arranged on the surface of the disc.

[0009] Furthermore, the solid-liquid separation component also includes an edge cavity, a spring rod and a first movable ball. The inner part of the disk is provided with an edge cavity in a ring shape, and the inner part of the edge cavity is penetrated by a spring rod, and the outer end of the spring rod is embedded with a first movable ball.

[0010] Furthermore, the solid-liquid separation component also includes a central cavity, a flange disk and a flange plug-in shaft. The central cavity is opened in the middle of the inner wall of the disk, and the flange disk is rotatably connected inside the central cavity. The surface of the flange disk is connected to the flange plug-in shaft.

[0011] Furthermore, the inner end of the spring rod is located inside the central cavity, and the convex edge of the convex plate is attached to the inner wall surface of the central cavity.

[0012] Furthermore, the solid-liquid separation component also includes a second movable ball, and the second movable balls are embedded equidistantly on both sides of the protruding portion of the convex edge plug-in shaft.

[0013] Furthermore, the solid-liquid separation component also includes a plug-in slide groove, and the plug-in slide groove is provided inside the reciprocating screw rod.

[0014] Furthermore, the inner mouth structure of the plug-in groove is adapted to the outer mouth structure of the convex plug-in shaft, and the convex plug-in shaft is slidably connected to the reciprocating screw through the second movable ball and the plug-in groove, the convex plug-in shaft passes through the interior of the conical sleeve, and the convex disk forms a transmission structure through the convex plug-in shaft and the reciprocating screw.

[0016] The present invention provides a wastewater treatment device for electroplating production, which has the following beneficial effects: 1. The electroplating production wastewater treatment equipment has a movable sleeve that rises and falls along the surface of the reciprocating screw rod, so that the tapered sleeve and the disc rise and fall inside the separation drum, whereby the brush strips are attached to the inner wall of the separation drum and lifted to clean its micropores, and at the same time, the transmission shaft rotates the brush sleeve on its surface and also adheres to the outer wall of the separation drum for rotation, whereby the brush sleeve also cleans the micropores on the surface of the separation drum from the outside to enhance the anti-clogging effect of the micropores, and when the disc rises and falls, the wastewater is pushed to the edge of the disc by the lifting of the lower cone and the tapered sleeve, so that the wastewater can flow through the gap and the water hole, so as to prevent the wastewater from being taken out of the separation drum due to the lifting of the disc, and at the same time facilitate the wastewater to better contact with the inner wall of the separation drum, so that the wastewater is quickly subjected to the centrifugal force, so that the liquid passes through the micropores and is separated from the solid crystals.

[0017] 2. In the electroplating wastewater treatment equipment, when the reciprocating screw rotates, the plug-in slot inside the screw drives the convex plug-in shaft to rotate, so that the convex disk rotates inside the central cavity. During the rotation of the convex disk, the convex portion contacts the inner ends of the spring rods at different positions in turn to push them, so that the spring rods continuously perform piston expansion and contraction movements under the action of their own elasticity, so that the first movable ball can continuously pass through the brush bar to impact the inner wall of the separation drum, thereby causing the crystals retained on the inner surface of the separation drum to be transported by the vibration force, so that they can be more conveniently cleaned by the brush bar.

[0018] 3. In the electroplating wastewater treatment equipment, the convex plug-in shaft slides and rises along the plug-in chute during the lifting process, thereby realizing the synchronous lifting of the disc while the convex disc rotates, and second movable balls are equidistantly embedded on both sides of the protruding part of the convex plug-in shaft, thereby facilitating the conversion of sliding friction between the convex plug-in shaft and the plug-in chute into rolling friction, facilitating the reduction of friction, and preventing the convex plug-in shaft from getting stuck during the lifting.

[0019] 4. The surface of the slope plate of the electroplating production wastewater treatment equipment is in a spiral ascending structure, and its lowest point is attached to the bottom of the inner wall of the separation drum. During the rotation of the separation drum, the slope plate pushes the wastewater deposited at the bottom upward, thereby preventing the deposition of debris in the wastewater, so that the wastewater can be better separated into solid and liquid. The outer wall of the movable rod of the spring telescopic rod is covered with a corrugated sleeve. When the movable rod part is extended and retracted due to the lifting and lowering of the disc, the corrugated sleeve is extended and retracted accordingly, so as to protect the part of the movable rod that penetrates the outer tube surface from being exposed, so as to prevent impurities from getting stuck in the gap and affecting the normal extension and retraction of the movable rod.

DETAILED DESCRIPTION

[0022] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figure 1-Figure 10As shown, the present invention provides a technical solution: a wastewater treatment device for electroplating production, comprising a working cylinder 1 and a solid-liquid separation component 3, a water inlet pipe 2 is penetrated on one side of the top of the working cylinder 1, the solid-liquid separation component 3 is arranged at the bottom of the working cylinder 1, and the solid-liquid separation component 3 comprises a driving motor 301, a rotating shaft 302, a separation rotating cylinder 303, a transmission shaft 304, a transmission belt 305, a rotating gear 306, a force-bearing gear 307, a reciprocating screw rod 308, a moving sleeve 309, a conical pipe sleeve 310, a disc 311 and a brush strip 312, the top of the driving motor 301 is connected to the rotating shaft 302, and the top of the rotating shaft 302 is fixed with the separation rotating cylinder 3 03, a transmission shaft 304 is distributed in parallel on the outer side of the separation drum 303, and a transmission belt 305 is meshed and connected to the bottom of the transmission shaft 304 and the surface of the rotating shaft 302, a rotating gear 306 is fixed on the top of the transmission shaft 304, and a force-bearing gear 307 is meshed and connected to one side of the rotating gear 306, a reciprocating screw rod 308 is connected to the bottom of the force-bearing gear 307, and a moving sleeve 309 is sleeved on the outer wall of the reciprocating screw rod 308, and a tapered sleeve 310 is connected to the outer wall of the moving sleeve 309 through a support rod, and a disc 311 is fixed to the bottom of the tapered sleeve 310, and a brush strip 312 is distributed on the outer side of the disc 311 in a ring shape; The specific operation is as follows: the water inlet pipe 2 injects the wastewater containing crystals into the separation drum 303 at a uniform speed, and the driving motor 301 drives the rotating shaft 302 to rotate the separation drum 303, so that the wastewater inside the separation drum 303 can pass through the micropores on the surface of the separation drum 303 under the centrifugal force and sprinkle into the working drum 1, and the mother liquid finally separated is discharged through the drain pipe; When the rotating shaft 302 rotates, the transmission belt 305 will also drive the transmission shaft 304 to rotate, so that the rotating gear 306 drives the force-bearing gear 307 to carry the reciprocating screw 308 to rotate, so that the movable sleeve 309 rises and falls along the surface of the reciprocating screw 308, and the conical sleeve 310 and the disc 311 rise and fall inside the separation drum 303, so that the brush strip 312 will stick to the inner wall of the separation drum 303 and rise and fall to clean its micropores, thereby preventing the micropores on the surface of the separation drum 303 from being blocked due to crystal aggregation.

[0024] like Figure 1-Figure 10 As shown, the solid-liquid separation component 3 further includes a brush sleeve 313, and the outer wall of the transmission shaft 304 is provided with a brush sleeve 313; The specific operation is as follows: the brush strip 312 is raised and lowered against the inner wall of the separation drum 303 to clean its micropores, and at the same time, the transmission shaft 304 rotates, and the brush cover 313 on its surface is also rotated against the outer wall of the separation drum 303, thereby the brush cover 313 also cleans the micropores on the surface of the separation drum 303 from the outside to enhance the anti-clogging effect of the micropores.

[0025] like Figure 1-Figure 10As shown, the solid-liquid separation component 3 also includes a lower cone 314 and a water hole 315. The lower cone 314 is fixed to the bottom of the disc 311, and the water hole 315 is evenly opened on the surface of the disc 311. A spring telescopic rod 4 is embedded in the bottom end of the lower cone 314, and a slope panel 5 is fixed to the outer wall of the movable rod end of the spring telescopic rod 4. A connecting bearing 6 is provided at the movable rod end of the spring telescopic rod 4, and a corrugated sleeve 7 is provided on the outer wall of the movable rod of the spring telescopic rod 4. The specific operation is as follows: the outer diameter of the disc 311 is smaller than the inner diameter of the separation drum 303, and the surface of the disc 311 has a water hole 315, so that when the disc 311 is raised or lowered, the wastewater is pushed to the edge of the disc 311 by the lower cone 314 and the conical sleeve 310, so that the wastewater can flow through the gap and the water hole 315, so as to prevent the wastewater from being taken out of the separation drum 303 due to the lifting of the disc 311, wherein the height of the conical sleeve 310 is always higher than the wastewater liquid level height inside the separation drum 303, thereby preventing the wastewater from entering the conical sleeve 310, and the wastewater is pushed to the edge so as to better contact with the inner wall of the separation drum 303, so that the wastewater is quickly subjected to the centrifugal force, so that the liquid passes through the micropores and is separated from the solid crystals; The movable rod end of the spring telescopic rod 4 is rotatably connected to the bottom of the inner wall of the separation drum 303 through the connecting bearing 6. When the lower cone 314 rises and falls with the disc 311, the spring telescopic rod 4 is adaptively extended and retracted through its own elastic function, so that the slope panel 5 is always located at the bottom of the inner wall of the separation drum 303. The surface of the slope panel 5 has a spiral ascending structure and its lowest point is attached to the bottom of the inner wall of the separation drum 303. During the rotation of the separation drum 303, the slope panel 5 pushes the wastewater deposited at the bottom upward, thereby preventing the deposition of debris in the wastewater, so that the wastewater can be better separated from the solid and liquid. The outer wall of the movable rod of the spring telescopic rod 4 is provided with a corrugated sleeve 7. When the movable rod part is extended and retracted due to the rise and fall of the disc 311, the corrugated sleeve 7 is extended and retracted accordingly to protect the penetration part of the movable rod on the outer tube surface from being exposed, so as to prevent impurities from being stuck in the gap and affecting the normal extension and retraction of the movable rod.

[0026] like Figure 1-Figure 10As shown, the solid-liquid separation component 3 also includes an edge cavity 316, a spring rod 317 and a first movable ball 318. The inner part of the disk 311 is provided with an edge cavity 316 in a ring shape, and the inner part of the edge cavity 316 is penetrated with a spring rod 317, and the outer end of the spring rod 317 is embedded with a first movable ball 318. The solid-liquid separation component 3 also includes a central cavity 319, a flange disk 320 and a flange plug-in shaft 321. The central cavity 319 is provided in the middle of the inner wall of the disk 311, and the inner part of the central cavity 319 is rotatably connected with a The flange disc 320 is connected to a flange plug-in shaft 321 on the surface of the flange disc 320. The inner end of the spring rod 317 is located inside the central cavity 319, and the flange edge of the flange disc 320 is attached to the inner wall surface of the central cavity 319. The solid-liquid separation component 3 also includes a plug-in slot 323. The plug-in slot 323 is provided inside the reciprocating screw rod 308. The flange plug-in shaft 321 passes through the interior of the conical sleeve 310, and the flange disc 320 and the reciprocating screw rod 308 form a transmission structure through the flange plug-in shaft 321. The specific operation is as follows. When the reciprocating screw 308 rotates, the convex plug-in shaft 321 will be driven to rotate through the plug-in groove 323 inside it, so that the convex disk 320 rotates inside the central cavity 319. During the rotation of the convex disk 320, the convex part contacts the inner ends of the spring rods 317 at different positions in turn to push them, so that the spring rods 317 continuously perform piston expansion and contraction movements under the action of their own elasticity, so that the first movable ball 318 can continuously pass through the brush strip 312 to hit the inner wall of the separation drum 303, thereby making the crystals retained on the inner surface of the separation drum 303 receive the shock force and be transported, so that they are more convenient to be cleaned by the brush strip 312. When the first movable ball 318 contacts the inner wall of the separation drum 303, the sliding friction can be converted into rolling friction, so as to avoid wear of the interior of the separation drum 303 due to long-term hard collision.

[0027] like Figure 1-Figure 10 As shown, the solid-liquid separation component 3 also includes a second movable ball 322, and the second movable balls 322 are equidistantly embedded on both sides of the protruding part of the convex plug-in shaft 321, the inner opening structure of the plug-in slot 323 is adapted to the outer opening structure of the convex plug-in shaft 321, and the convex plug-in shaft 321 is slidably connected to the reciprocating screw 308 through the second movable ball 322 and the plug-in slot 323; The specific operation is as follows: the flange disk 320 and the flange plug-in shaft 321 rise and fall synchronously with the circular disk 311. Therefore, the flange plug-in shaft 321 slides and rises along the plug-in groove 323 during the lifting process, thereby realizing the flange disk 320 rotating while coordinating with the synchronous lifting of the circular disk 311, and the second movable balls 322 are equidistantly embedded on both sides of the protruding part of the flange plug-in shaft 321, which is conducive to converting the sliding friction between the flange plug-in shaft 321 and the plug-in groove 323 into rolling friction, which is conducive to reducing the friction force to prevent the lifting and lowering of the flange plug-in shaft 321 from getting stuck.

[0028] In summary, if Figure 1-Figure 10 As shown, when the electroplating production wastewater treatment equipment is used, firstly, the water inlet pipe 2 uniformly injects the wastewater containing crystals into the separation drum 303, and the driving motor 301 drives the rotating shaft 302 to rotate the separation drum 303, so that the wastewater inside the separation drum 303 can pass through the micropores on the surface of the separation drum 303 under the centrifugal force and sprinkle into the working drum 1, and the mother liquid finally separated is discharged through the drain pipe; When the rotating shaft 302 rotates, the transmission belt 305 also drives the transmission shaft 304 to rotate, so that the rotating gear 306 drives the force-bearing gear 307 to carry the reciprocating screw 308 to rotate, so that the movable sleeve 309 rises and falls along the surface of the reciprocating screw 308, so that the conical pipe sleeve 310 and the disc 311 rise and fall inside the separation drum 303, so that the brush strip 312 will be attached to the inner wall of the separation drum 303 and rise and fall to clean its micropores, thereby preventing the micropores on the surface of the separation drum 303 from being blocked due to crystal aggregation. At the same time, the brush sleeve 313 on the surface of the transmission shaft 304 rotates and also sticks to the outer wall of the separation drum 303 to rotate, so that the brush sleeve 313 will also clean the micropores on the surface of the separation drum 303 from the outside to enhance the anti-blocking effect of the micropores; The outer diameter of the disc 311 is smaller than the inner diameter of the separation drum 303, and the surface of the disc 311 has water holes 315, so that when the disc 311 is raised or lowered, the wastewater is pushed to the edge of the disc 311 by the lower cone 314 and the conical sleeve 310, so that the wastewater can flow through the gap and the water holes 315, so as to prevent the wastewater from being taken out of the separation drum 303 due to the lifting of the disc 311, wherein the height of the conical sleeve 310 is always higher than the wastewater liquid level height inside the separation drum 303, thereby preventing the wastewater from entering the conical sleeve 310, and the wastewater is pushed to the edge so as to better contact with the inner wall of the separation drum 303, so that the wastewater is quickly subjected to the centrifugal force, so that the liquid passes through the micropores and is separated from the solid crystals; When the reciprocating screw 308 rotates, the convex plug-in shaft 321 is driven to rotate through the plug-in slot 323 inside it, so that the convex disc 320 rotates inside the central cavity 319. During the rotation of the convex disc 320, the convex edge part contacts the inner end of the spring rod 317 at different positions in turn to push it, so that the spring rod 317 continuously performs piston expansion and contraction movement under its own elastic action, so that the first movable ball 318 can continuously pass through the brush strip 312 to hit the inner wall of the separation drum 303, thereby causing the crystals retained on the inner surface of the separation drum 303 to be transported by the shock force, so that it is more convenient to be cleaned by the brush strip 312, and when the first movable ball 318 contacts the inner wall of the separation drum 303, the sliding friction can be converted into rolling friction, so as to avoid the wear of the separation drum 303 due to long-term hard collision. The flanged disc 320 and the flanged plug-in shaft 321 are lifted and lowered synchronously with the disc 311. Therefore, the flanged plug-in shaft 321 is slid and lifted along the plug-in slide groove 323 during the lifting process, thereby realizing that the flanged disc 320 rotates while cooperating with the synchronous lifting and lowering of the disc 311. The second movable balls 322 are equidistantly embedded on both sides of the protruding part of the flanged plug-in shaft 321, thereby facilitating the sliding friction between the flanged plug-in shaft 321 and the plug-in slide groove 323 to be converted into rolling friction, thereby facilitating the reduction of friction, so as to prevent the flanged plug-in shaft 321 from being stuck when being lifted and lowered. The spring telescopic rod 4 is rotatably connected to the bottom of the inner wall of the separation drum 303 through the connecting bearing 6. When the lower cone 314 rises and falls with the disc 311, the spring telescopic rod 4 is adaptively extended and retracted through its own elastic function, so that the slope panel 5 is always located at the bottom of the inner wall of the separation drum 303. The surface of the slope panel 5 is a spirally ascending structure, and its lowest point is attached to the bottom of the inner wall of the separation drum 303. During the rotation of the separation drum 303, the slope panel 5 pushes the wastewater deposited at the bottom upward, thereby preventing the deposition of debris in the wastewater, so that the wastewater can be better separated from the solid and liquid. The outer wall of the movable rod of the spring telescopic rod 4 is provided with a corrugated sleeve 7. When the movable rod part is extended and retracted due to the rise and fall of the disc 311, the corrugated sleeve 7 is extended and retracted accordingly to protect the penetration part of the movable rod on the outer tube surface from being exposed, so as to prevent impurities from being stuck in the gap and affecting the normal extension and retraction of the movable rod.
