Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a metal surface treatment wastewater treatment device. Background Art

[0002] Metal is a substance with lustre (i.e. strong reflection of visible light), ductility, and good electrical and thermal conductivity. The vast majority of metal elements on Earth exist in nature in a combined state. This is because the chemical properties of most metals are relatively active, and only a very small number of metals, such as gold and silver, exist in a free state. Metals are widely present in nature and are widely used in life. They are a very important and most widely used type of substance in modern industry. However, during long-term use, the surface of metals will inevitably corrode and produce rust. Therefore, it is necessary to treat the surface, and direct discharge of treated wastewater will pollute the environment.

[0003] According to announcement number CN 110228895 B, a metal surface treatment wastewater treatment device comprises a wastewater treatment tank, and a membrane assembly, a water leakage baffle, a transfer mechanism and a stirring mechanism arranged in the wastewater treatment tank from bottom to top.

[0004] The device can more effectively remove metals from the wastewater, and at the same time prevent sludge from adhering to the surface of the membrane assembly, which helps the membrane assembly to filter the wastewater normally and avoids damage to the membrane assembly. After the device treats the wastewater, it will fall on the leaking baffle, and the heavy metal ions, organic matter, acid and alkali substances on the leaking baffle will remain on the top, but the device does not treat the heavy metal ions, organic matter, acid and alkali substances, etc., which will affect the fall of the treated wastewater over time.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. The metal surface treatment wastewater treatment device injects wastewater into the box through the first feed pipe through the stirring mechanism, and then injects the coagulant into the box through the second feed pipe to combine with the wastewater in the box, and then puts the acid-base neutralizer in the hopper, and injects the acid-base neutralizer into the box through the connecting tube to mix with the wastewater and the coagulant, and then starts the first motor to rotate the connecting shaft. The rotation of the connecting shaft will drive the first rotating plate and the second rotating plate to rotate, thereby driving the two stirring blades and the two stirring shafts to rotate. Since the first gear is meshed with the second gear and the first gear is fixed, the two stirring shafts will rotate while they are revolving. The wastewater, coagulant and acid-base neutralizer in the box can be evenly mixed through the revolution of the two stirring blades and the two stirring shafts and the rotation of the two stirring shafts, so that the heavy metal ions, organic matter, acid-base substances, etc. in the wastewater can be effectively separated.

[0021] 2. The metal surface treatment wastewater treatment device, through the scraping mechanism set up, after the heavy metal ions, organic matter, acid and alkali substances in the wastewater are separated, the wastewater in the box is discharged from the connecting pipe through the control valve and falls on the grid plate, while the heavy metal ions, organic matter, acid and alkali substances, etc. will remain on the grid plate, and the rest of the wastewater will be discharged through the discharge pipe. When the wastewater is discharged, the cylinder is started to drive the second fixed plate and the ring to move to the left, thereby driving the ring to move to the left, and further driving the second sliding sleeve to move to the left on the surface of the screw, so that the limit block slides into the second limit groove, and the third shaft and the screw are connected through the limit block, and then through The first motor rotates the first pulley, and the first pulley rotates the first shaft through the cooperation of the first belt. The first shaft drives the third pulley to rotate. The third pulley rotates the fourth pulley through the cooperation of the second belt, thereby driving the second shaft to rotate, thereby rotating the first bevel gear. The first bevel gear rotates through the cooperation of the second bevel gear and the third shaft, thereby driving the screw to rotate. The rotation of the screw drives the connecting plate and the scraper to move to the left, thereby driving the heavy metal ions, organic matter, acid-base substances, etc. on the top of the grille plate to move to the left, thereby discharging these substances from the box.

[0022] 3. The metal surface treatment wastewater treatment device, through the filter mechanism set up, the wastewater is discharged into the filter box through the discharge pipe, the wastewater will flow to the filter plate, the filter plate will filter the tiny particles and suspended matter in the wastewater, and the filtered wastewater will be discharged through the water outlet cover and the outlet pipe. When the filter plate needs to be replaced, the crank handle is turned to rotate the fourth shaft, the fourth shaft drives the third gear to rotate, the third gear drives the rack to move forward, thereby driving the pressure block forward and backward, and then the filter plate is pulled out of the filter box, and then the new filter plate is slid into the filter box, and then the crank handle is released, and then the rack and the pressure block will move backward through the elastic force of the spring, and the back of the pressure block will fit tightly with the front of the new filter plate, so that the filter plate is tightly located in the filter box.

[0023] 4. The metal surface treatment wastewater treatment device detects the pH value of the wastewater in the box through the quantitative mechanism and the pH meter. When the pH value of the wastewater in the box is too low, the second motor is started to rotate the worm, and the rotation of the worm drives the worm wheel to rotate. The worm drives the fifth shaft to rotate, thereby driving the quantitative disk to rotate, and further drives the gap between the quantitative disk and the inner wall of the connecting tube to adjust the gap. The acid and alkali agent in the hopper will be injected into the box through the connecting tube, and then the pH meter is observed until the pH value of the wastewater in the box reaches a neutral state.

[0057] Furthermore, the quantitative mechanism 9 includes a connecting cylinder 91, which is fixedly connected to the top of the box body 3 near the back, a hopper 92 is fixedly connected to the top of the connecting cylinder 91, a fixed block 93 is symmetrically fixedly connected to the surface of the connecting cylinder 91, a fifth rotating shaft 94 is provided on the surface of the fixed block 93, a quantitative disk 95 is fixedly connected to the surface of the fifth rotating shaft 94, a second fixed sleeve 96 is fixedly connected to the top of the box body 3 near the back, a second motor 97 is fixedly connected in the second fixed sleeve 96, a worm 98 is fixedly connected to the output end of the second motor 97, and a worm gear 99 is fixedly connected to the surface of the rotating shaft near the front end.

[0058] Furthermore, a hole matching the fifth rotating shaft 94 is opened on the side of the fixing block 93 away from the connecting tube 91 and on the surface of the connecting tube 91 , and the surface of the fifth rotating shaft 94 passes through and is rotatably connected in the hole, and the worm 98 is meshed with the worm wheel 99 .

[0059] In actual operation, when the device is used, wastewater is injected into the box body 3 through the first feed pipe 4, and then the coagulant is injected into the box body 3 through the second feed pipe 5 to combine with the wastewater in the box body 3. Then, the acid-base neutralizer is placed in the hopper 92, and the acid-base neutralizer is injected into the box body 3 through the connecting tube 91 to mix with the wastewater and the coagulant. Then, the first motor 712 is started to rotate the connecting shaft 713. The rotation of the connecting shaft 713 drives the first rotating plate 714 and the second rotating plate 715 to rotate, thereby The two stirring blades 716 and the two stirring shafts 719 are driven to rotate. Since the first gear 718 is meshed with the second gear 7111 and the first gear 718 is fixed, the two stirring shafts 719 will also rotate while revolving. The two stirring blades 716 and the two stirring shafts 719 can be rotated by the revolution and the rotation of the two stirring shafts 719 to uniformly mix the wastewater, coagulant and acid-base neutralizer in the box 3, so that the heavy metal ions, organic matter, acid-base substances, etc. in the wastewater can be effectively separated.

[0060] After the heavy metal ions, organic matter, acid-base substances, etc. in the wastewater are separated, the wastewater in the box 3 is discharged from the connecting pipe 7113 through the control valve 7114 and falls on the grid plate 7222, while the heavy metal ions, organic matter, acid-base substances, etc. will remain on the grid plate 7222, and the rest of the wastewater will be discharged through the discharge pipe 6. When the wastewater is discharged, the cylinder 7229 is started to drive the second fixed plate 7228 and the ring 7227 to move left, thereby driving the ring 7227 to move left, and further driving the second sliding sleeve 7224 to move left on the surface of the screw 7215, so that the limit block 7225 slides into the second limit groove 7226, and the third rotating shaft 7213 and the screw 7215 are connected through the limit block 7225, and then the first pulley 7228 is driven by the operation of the first motor 712. 23 is rotated, the first pulley 723 rotates the first rotating shaft 722 through the cooperation of the first belt 725, the first rotating shaft 722 drives the third pulley 726 to rotate, the third pulley 726 rotates the fourth pulley 729 through the cooperation of the second belt 7211, thereby driving the second rotating shaft 728 to rotate, thereby rotating the first bevel gear 7212, the first bevel gear 7212 rotates through the cooperation of the third rotating shaft 7213 of the second bevel gear 7214, thereby driving the screw 7215 to rotate, the rotation of the screw 7215 drives the connecting plate 7217 and the scraper 7218 to move leftward, thereby driving the heavy metal ions, organic matter, acid-base substances, etc. on the top of the grid plate 7222 to move leftward, thereby discharging these substances from the box body 3;

[0061] The waste water is discharged into the filter box 81 through the discharge pipe 6, and the waste water will flow to the filter plate 82, and the filter plate 82 will filter the tiny particles and suspended matter in the waste water, and the filtered waste water will be discharged through the water outlet cover 83 and the water outlet pipe 84. When the filter plate 82 needs to be replaced, the crank 815 is turned to rotate the fourth shaft 814, and the fourth shaft 814 drives the third gear 816 to rotate, and the third gear 816 drives the rack 811 to move forward, thereby driving the pressing block 812 forward and backward, and then the filter plate 82 is pulled out of the filter box 81, and then the new filter plate 82 is slid into the filter box 81, and then the crank 815 is released, and then the rack 811 and the pressing block 812 will move backward by the elastic force of the spring 89, and the back of the pressing block 812 will fit tightly with the front of the new filter plate 82, so that the filter plate 82 is tightly located in the filter box 81;

[0062] The pH meter 31 detects the pH value of the wastewater in the box 3. When the pH value of the wastewater in the box 3 is too low, the second motor 97 is started to rotate the worm 98. The rotation of the worm 98 drives the worm wheel 99 to rotate, and the worm 98 drives the fifth shaft 94 to rotate, thereby driving the quantitative disk 95 to rotate, and further drives the gap between the quantitative disk 95 and the inner wall of the connecting tube 91 to be adjusted. The acid and alkali agent in the hopper 92 will be injected into the box 3 through the connecting tube 91, and then the pH meter 31 is observed until the pH value of the wastewater in the box 3 reaches a neutral state.
