Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to an industrial welding line wastewater treatment device. Background Art

[0002] Wastewater treatment is an important environmental protection work, which mainly includes the following steps and methods:

[0003] Pretreatment, primary treatment, secondary treatment, deep treatment, and disinfection.

[0004] In actual operation, it is necessary to select a suitable treatment process combination according to factors such as the type, concentration, and discharge volume of wastewater. At the same time, it is necessary to continuously optimize the treatment process and parameters, improve treatment efficiency and effect, and reduce treatment costs. Wastewater treatment is of vital importance to protecting water resources, maintaining ecological balance, and safeguarding human health.

[0005] When it comes to wastewater treatment from industrial welding lines, during welding operations such as arc welding and gas shielded welding, welding wires and welds will produce metal oxides, slag, etc. at high temperatures, some of which will enter the cooling water in the form of tiny particles to form wastewater. The workpieces after welding may need to be cleaned to remove welding slag, oil stains, etc. generated during the welding process. The cleaning process will produce wastewater containing these pollutants. These two types of wastewater each contain substances that need to be extracted and removed. If only the metal particles in the wastewater are treated, the oil stains will be removed along with the metal particles, and will need to be cleaned up later. Summary of the invention

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention sets a separation mechanism. When the wastewater is poured into the side of the processing bin close to the collection box, the wastewater will be behind the middle plate at the beginning until the horizontal plane reaches the water flow trough. Since the welding wire and the weldment will produce metal oxides, slag, etc. at high temperature, the density of these particles is greater than that of water and they will sink to the bottom of the water. The workpiece after welding may need to be cleaned to remove the welding slag and oil stains generated during the welding process. The oil stains in the wastewater generated by cleaning will enter the other side of the middle plate along the water flow trough, thereby realizing the separation of metal and oil stains.

[0022] 2. The present invention sets a buoyancy mechanism. After the oil and dirt are separated, all the wastewater in the treatment chamber one needs to flow into the next mechanism. As the level of the wastewater rises, the buoyancy plate will drive the support plate one to move upward, and drive the water baffle plate to move upward as well. When the support plate moves to the same level as the magnetic plate one, the magnetic plate one absorbs the magnetic plate two, so that the magnetic plate two and the sliding column are against the top of the middle plate, so that the water baffle plate will not fall, so that all the water in the subsequent treatment chamber one flows into the treatment chamber two.

[0023] 3. The present invention sets a collection mechanism. When the water is discharged into the mechanism, the servo motor drives the rotating block to rotate, and then retracts the wire, so that the storage plate is pulled upward, and the storage plate moves along the direction of the guide rod. When it moves to the top, the positioning block and the guide rod will cause the storage plate to tilt at a certain angle. After that, due to the gravity of the push plate, it will move along the three-way tilt direction of the support column, and scrape the metal particles that fall on the storage plate into the collection box, which is convenient for subsequent recycling.

[0024] 4. The present invention sets a sedimentation mechanism. When the wastewater enters the treatment chamber 2, the servo motor 2 will regularly drive the hollow shaft and the stirring plate to rotate, thereby causing the wastewater in the treatment chamber 2 and the sedimentation chamber to circulate. When the servo motor 2 is not working, the liquid outlet will drip the solution containing hydroxide in the reagent chamber into the sedimentation chamber. The hydroxide will react chemically with the heavy metals in the wastewater to form a precipitate. Since the solution drips into the sedimentation chamber, the precipitate will be in the sedimentation chamber. The precipitate can be easily removed by directly taking out the sedimentation chamber. Due to the elasticity of the telescopic spring 2, the scratch plate is above the wastewater level, so that the precipitate will not precipitate on the scratch plate. By pressing the pressing plate downward, the scratch plate will be driven to scrape off the precipitate precipitated on the stirring plate. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0041] Example 1, using Figure 1-Figure 14 An industrial welding line wastewater treatment device according to one embodiment of the present invention is described as follows.

[0042] like Figure 1-Figure 2As shown, an industrial welding line wastewater treatment device of the present invention comprises a bottom plate 1, an operation box 2 is fixedly connected to the right side of the bottom plate 1, a box pad 3 is evenly arranged on the top of the bottom plate 1, the bottom of the box pad 3 is fixedly connected to the top of the bottom plate 1, a treatment box 4 is fixedly connected to the top of the box pad 3, a water pipe 5 is fixedly connected to the outer surface of the treatment box 4, a valve 6 is evenly arranged at one end of the water pipe 5 close to the treatment box 4, a partition plate 11 is symmetrically arranged on the inner wall of the treatment box 4, the partition plate 11 evenly divides the treatment box 4 into three spaces, a detection mechanism 9 is fixedly connected to one end of the treatment box 4 close to the operation box 2, and a disinfection chamber 10 is arranged on the inner wall of the treatment box 4;

[0043] An iron-dirt separation mechanism 7, which is used to separate metal blocks and impurities and collect metal waste;

[0044] A heavy metal separation mechanism 8, the heavy metal separation mechanism 8 is used to extract heavy metals in wastewater;

[0045] When an industrial welding line wastewater treatment device is working, the waste is first poured into the iron-pollution separation mechanism 7, which will separate the metal particles and oil pollution in the wastewater, and then collect the metal particles. The wastewater then enters the heavy metal separation mechanism 8 through the water pipe 5, thereby separating the heavy metals in the wastewater. At the same time, the detection mechanism 9 will detect whether there are any residual flocculants and hydroxides in the wastewater. Finally, the wastewater enters the disinfection chamber 10 through the water pipe 5 for disinfection treatment, and then is discharged from the water pipe 5.

[0046] like Figure 3-Figure 4 As shown, the iron-contamination separation mechanism 7 comprises a processing chamber 71, a water spray device 72 is fixedly connected to the bottom of the processing chamber 71, a water inlet 73 is fixedly connected to the top of the water spray device 72, a filter plate 78 is fixedly connected to one end of the processing chamber 71 close to the water pipe 5, a sealing plate 74 is threadedly connected to the outer surface of the processing chamber 71, a partition mechanism 75 is fixedly connected to the middle of the processing chamber 71, a collection box 77 is fixedly connected to one end of the processing chamber 71 away from the filter plate 78, and a collection mechanism 76 is fixedly connected to the top of the collection box 77;

[0047] like Figure 5-Figure 6 As shown, the partition mechanism 75 includes an intermediate plate 751, a water flow trough 752 is arranged on the top of the intermediate plate 751, support columns 753 are symmetrically arranged on the outer surface of the intermediate plate 751, and a buoyancy mechanism 754 is slidably connected to the outer surface of the support column 753, a magnetic plate 755 is symmetrically arranged on the top of the intermediate plate 751, and blocking columns 756 are evenly arranged on the bottom of the intermediate plate 751, the top of the blocking column 756 is fixedly connected to the bottom of the intermediate plate 751, and the bottom of the blocking column 756 is fixedly connected to the inner wall of the processing chamber 71.

[0048] When waste water is poured into the side of the processing bin close to the collection box 77, the waste water will be at the rear of the middle plate 751 at the beginning until the horizontal plane reaches the water flow trough 752. Since the welding wire and welded parts will produce metal oxides, slag, etc. at high temperature, the density of these particles is greater than that of water and they will sink to the bottom of the water. The workpiece after welding may need to be cleaned to remove the welding slag and oil generated during the welding process. The oil in the waste water generated by cleaning will enter the other side of the middle plate 751 along the water flow trough 752, thereby realizing the separation of metal and oil.

[0049] The processing chamber 1 71 is arranged on a side of the processing box 4 away from the disinfection chamber 10 , and the outer surface of the middle plate 751 is fixedly connected to the inner wall of the processing chamber 1 71 .

[0050] like Figure 7-Figure 8 As shown, the buoyancy mechanism 754 includes a sliding plate 7541, the bottom of the sliding plate 7541 is fixedly connected to a drooping rod 7542, the bottom of the drooping rod 7542 is fixedly connected to a water retaining plate 7543, the end of the sliding plate 7541 away from the support column 753 is fixedly connected to the buoyancy plate 7544, the top of the sliding plate 7541 is fixedly connected to a support plate 7545, the outer surface of the support plate 7545 is fixedly connected to an L-shaped plate 7546, the end of the L-shaped plate 7546 away from the support plate 7545 is fixedly connected to a telescopic spring 7547, the end of the telescopic spring 7547 away from the L-shaped plate 7546 is fixedly connected to a support plate 2 7548, the outer surface of the support plate 2 7548 is fixedly connected to a sliding column 7549, and the end of the sliding column 7549 close to the support plate 1 7545 is fixedly connected to a magnetic plate 2 75410.

[0051] After the oil and dirt are separated, all the wastewater in the treatment chamber 71 needs to flow into the next mechanism. As the level of the wastewater rises, the buoyancy plate 7544 will drive the support plate 7545 to move upward, and drive the water retaining plate 7543 to move upward as well. When the support plate moves to the same level as the magnetic plate 755, the magnetic plate 1 755 absorbs the magnetic plate 2 75410, so that the magnetic plate 2 75410 and the sliding column 7549 are against the top of the middle plate 751, so that the water retaining plate 7543 will not fall, so that all the water in the subsequent treatment chamber 71 flows into the treatment chamber 2 81.

[0052] The outer surface of the sliding column 7549 is slidably connected to the inner wall of the L-shaped plate 7546, and the second magnetic plate 75410 is slidably connected to the inner wall of the supporting plate 1 7545.

[0053] After separation, the staff will introduce flocculants to the side with more oil stains and impurities, so that the oil stains and impurities are mixed together. The filter plate 1 78 will only allow the solution to flow out. After the wastewater flows into the treatment chamber 2 81, the water pipe 5 is connected to the water inlet 73 and the sealing plate 74 is opened. At the same time, the water spray device 72 is opened to flush out the oil stains and impurities.

[0054] like Figure 9-10 As shown, the collecting mechanism 76 includes a supporting column 761, the top of the supporting column 761 is fixedly connected with a coil block 762, the outer surface of the coil block 762 is fixedly connected with a servo motor 763, the output end of the servo motor 763 is fixedly connected with a rotating block 764, the outer surface of the rotating block 764 is fixedly connected with a wire 765, the bottom of the wire 765 is fixedly connected with a storage plate 766, the surface of the storage plate 766 is provided with a water leakage port 769, the top of the processing bin 71 is symmetrically provided with a positioning block 768, the bottom of the positioning block 768 is fixedly connected to the top of the processing bin 71, the inner wall of the storage plate 766 is slidably connected with a guide rod 767, support columns 7610 are symmetrically provided on both sides of the storage plate 766, and the outer surface of the support column 7610 is slidably connected with a push plate 7611.

[0055] The servo motor 763 drives the rotating block 764 to rotate, thereby retracting the wire 765, thereby pulling the storage plate 766 upward, and the storage plate 766 moves along the direction of the guide rod 767. When it moves to the top, the positioning block 768 and the guide rod 767 will cause the storage plate 766 to tilt at a certain angle. After that, due to the gravity of the push plate 7611, it will move along the support column three 7610 in the tilted direction, and scrape the metal particles that fall onto the storage plate 766 into the collection box 77 for subsequent recycling.

[0056] The bottom of the second support column 761 is fixedly connected to the top of the processing chamber 1 71 , and the inner wall of the processing chamber 1 71 is fixedly connected to the bottom of the guide rod 767 .

[0057] The specific workflow is as follows:

[0058] During operation, when waste water is poured into the side of the processing bin close to the collection box 77, the waste water will be at the rear of the middle plate 751 at the beginning until the horizontal plane reaches the water flow trough 752. Since the welding wire and the welded parts will produce metal oxides, slag, etc. at high temperature, the density of these particles is greater than that of water and they will sink to the bottom of the water. The welded workpiece may need to be cleaned to remove the welding slag and oil stains generated during the welding process. These oil stains will flow into the other side of the middle plate 751 along the water flow trough 752, and the servo motor 763 will drive the rotating block 764 to rotate, thereby retracting the wire 765, so that the storage When the plate 766 is pulled upward, the storage plate 766 will move in the direction of the guide rod 767. When it moves to the top, the positioning block 768 and the guide rod 767 will cause the storage plate 766 to tilt at a certain angle. Then, due to the gravity of the push plate 7611, it will move in the tilted direction along the support column three 7610, and scrape the metal particles that have fallen onto the storage plate 766 into the collection box 77. The buoyancy mechanism 754 will control all waste water to enter the treatment chamber two 81. Then, the water pipe 5 is connected to the water inlet 73 and the sealing plate 74 is opened. At the same time, the water spray device 72 is opened to flush out oil stains and impurities.

[0059] Embodiment 2, use Figure 1-Figure 14 An industrial welding line wastewater treatment device according to one embodiment of the present invention is described as follows.

[0060] like Fig.11 As shown, an industrial welding line wastewater treatment device of the present invention is based on the first embodiment, and the heavy metal separation mechanism 8 includes a second processing chamber 81, and the end of the second processing chamber 81 close to the water pipe 5 is fixedly connected to the second filter plate 82, the top of the second processing chamber 81 is fixedly connected to the reagent box 85, and the outer surface of the reagent box 85 is fixedly connected to the liquid outlet 86, the inner wall of the second processing chamber 81 is symmetrically provided with hanging plates 83, the outer surface of the hanging plates 83 is fixedly connected to the inner wall of the second processing chamber 81, and a sedimentation mechanism 84 is provided on the hanging plates 83.

[0061] like Figure 12-13 As shown, the sedimentation mechanism 84 includes a sedimentation box 841, a hanging rod 843 is symmetrically arranged on the top of the sedimentation box 841, a water outlet 842 is arranged on the outer surface of the sedimentation box 841, a servo motor 844 is fixedly connected to the bottom of the sedimentation box 841, a hollow rotating shaft 846 is fixedly connected to the output end of the servo motor 844, a stirring plate 845 is evenly arranged on the outer surface of the hollow rotating shaft 846, a telescopic spring 847 is fixedly connected to the inner wall of the hollow rotating shaft 846, a sliding rod 848 is fixedly connected to the top of the telescopic spring 847, a pressing plate 8411 is fixedly connected to the top of the sliding rod 848, a support rod 849 is fixedly connected to the end of the sliding rod 848 close to the pressing plate 8411, and a scratch plate 8410 is fixedly connected to the outer surface of the support rod 849.

[0062] First, hang the sedimentation mechanism 84 on the hanging plate 83. When the wastewater enters the treatment chamber 81, the servo motor 844 will regularly drive the hollow shaft 846 and the stirring plate 845 to rotate, thereby causing the wastewater in the treatment box 4 and the sedimentation box 841 to circulate. When the servo motor 844 is not working, the liquid outlet 86 will drip the solution containing hydroxide in the reagent box 85 into the sedimentation box 841. The hydroxide will react chemically with the heavy metals in the wastewater to form a precipitate. Since it drips into the sedimentation box 841, the precipitate will be in the sedimentation box 841. The sedimentation box 841 can be directly taken out to easily remove the precipitate. Due to the elasticity of the telescopic spring 847, the scratch plate 8410 is above the waste water level, so that the precipitate will not precipitate on the scratch plate 8410. By pressing the pressing plate 8411 downward, the scratch plate 8410 will be driven to scrape off the precipitate precipitated on the stirring plate 845.

[0063] The second processing chamber 81 is arranged between the first processing chamber 71 and the disinfection chamber 10 , the hanging rod 843 is placed on the hanging plate 83 , and the outer surface of the sliding rod 848 is slidably connected to the inner wall of the hollow rotating shaft 846 .

[0064] like Fig.14 As shown, the detection mechanism 9 includes a support plate three 91, a water pump 92 is fixedly connected to the top of the support plate three 91, a water suction pipe 93 is fixedly connected to the top of the water pump 92, the outer surface of the water pump 92 is fixedly connected to the water suction pipe 93, the end of the water suction pipe 93 away from the water pump 92 is fixedly connected to a control valve 95, the end of the control valve 95 away from the water outlet pipe 94 is symmetrically provided with a glass water pipe 96, and a support rod three 97 is symmetrically provided at the bottom of the support plate three 91, and a display water tank 98 is fixedly connected to the bottom of the support rod three 97.

[0065] After the sedimentation mechanism 84 has finished working, the water pump 92 will suck a part of the wastewater on the top layer of the treatment chamber 81 into the control valve 95 through the suction pipe 93. The control valve 95 will divide the wastewater into two parts and enter the glass water pipe 96 and the display water tank 98 respectively. It can be clearly seen in the glass tube whether the water is turbid. If the water is turbid, the surface flocculant is excessive. The wastewater will contact the phenolphthalein solution and the hydroxide solution respectively contained in the two display water tanks 98. If the phenolphthalein turns red, it means that too much hydroxide solution has been dripped in. If there is precipitation in the display water tank 98 filled with hydroxide solution, it means that there are still heavy metal components in the wastewater that have not been precipitated.

[0066] The specific workflow is as follows:

[0067] When working, first hang the sedimentation mechanism 84 on the hanging plate 83. When the wastewater enters the treatment chamber 81, the servo motor 844 will regularly drive the hollow shaft 846 and the stirring plate 845 to rotate, thereby causing the wastewater in the treatment box 4 and the sedimentation box 841 to circulate. When the servo motor 844 is not working, the liquid outlet 86 will drip the solution with hydroxide in the reagent box 85 into the sedimentation box 841. The hydroxide will react chemically with the heavy metals in the wastewater to form a precipitate. Since it is dripped into the sedimentation box 841, the precipitate will be in the sedimentation box 841. The sedimentation box 841 can be directly taken out to easily remove the sediment. Due to the elasticity of the telescopic spring 847, the scratch plate 8410 is above the wastewater level, so that the precipitate will not precipitate on the scratch plate. On the plate 8410, by pressing the pressing plate 8411 downward, the scratching plate 8410 will be driven to scrape off the precipitate precipitated on the stirring plate 845. After the sedimentation mechanism 84 has finished working, the water pump 92 will suck a part of the wastewater on the top layer of the treatment chamber 81 into the control valve 95 through the suction pipe 93. The control valve 95 will divide the wastewater into two parts and enter the glass water pipe 96 and the display water tank 98 respectively. It can be clearly seen in the glass tube whether the water body is turbid. If the water body is turbid, the surface flocculant is excessive. The wastewater will contact the phenolphthalein solution and the hydroxide solution respectively contained in the two display water tanks 98. If the phenolphthalein turns red, it means that too much hydroxide solution has been dripped in. If there is precipitation in the display water tank 98 filled with hydroxide solution, it means that there are still heavy metal components in the wastewater that have not been precipitated.
