Description

Technical Field

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

[0002] In addition to the organic wastewater after biochemical treatment, the manufacturing wastewater also contains a small amount of iron filings impurities produced by manufacturing. Due to the concentration of salinity in the raw water in the circulating water field and chemical water station and the enrichment by adding drugs, the discharged wastewater has the characteristic of high salt content. The pollutants are mainly total salt content (TDS), and some wastewater also contains difficult-to-degrade organic matter.

[0003] Existing recovery devices usually use filter plates directly to filter iron filings. This filtering method may cause iron filings impurities in industrial wastewater to adhere to the surface of the filter plate, and the iron filings impurities are easily accumulated in the area on one side of the filter, affecting the wastewater filtration efficiency. At the same time, the card slot connector part of the filter plate is easily corroded by the organic salt components in the industrial wastewater due to long-term contact with the industrial wastewater, causing the connector to rust and damage, making it easy for the filter plate to be unable to be pulled out, and further making it impossible to process the impurities adsorbed on the surface of the filter plate, thereby affecting the filtration effect.

[0004] Therefore, the present application provides an industrial wastewater recycling and treatment device to meet the needs. Summary of the invention

[0040] like Figures 1 to 13 As shown, an embodiment of the present invention provides an industrial wastewater recovery and treatment device, including a base 1, a support frame 2 is arranged on the top of the base 1, a wastewater tank 3 is connected to the inner side of the support frame 2, a mounting box 4 is connected to the bottom of the wastewater tank 3, the mounting box 4 is connected to an evaporation treatment tank 8 through a pipeline, a steam power generation module 9 is connected to one side of the evaporation treatment tank 8 through a pipeline, a collecting tank 10 is arranged below the mounting box 4, and also includes a filter assembly 5, the filter assembly 5 is installed on the inner side of the mounting box 4, and the filter assembly 5 is used to filter and treat the industrial wastewater. The filter assembly 5 includes a gate 51, which is installed on the inner side of the installation box 4. The inner side of the installation box 4 is respectively provided with a first filter plate 58, a second filter plate 59 and a third filter plate 510; a scraper assembly 6, which is equidistantly installed on the outer side of the installation box 4, and is used to scrape iron filings and other impurities from the filter assembly 5; an anti-corrosion assembly 7, which is installed on one side of the installation box 4, and is located below the scraper assembly 6. The anti-corrosion assembly 7 is used to spray anti-corrosion protective oil on the connector of the filter assembly 5.

[0041] As 1 to Figure 4As shown, the gate 51 slides in the inner groove of the installation box 4, a cylinder 52 is connected to one side of the gate 51, and the cylinder 52 is installed on the bracket of the installation box 4. The output end of the cylinder 52 is connected to a rack 1 53, and the rack 1 53 slides in the inner groove of the installation box 4. The rack 1 53 and the gear 1 54 are meshed with each other, and the gear 1 54 rotates on the inner wall of the installation box 4. The gear 1 54 and the rack 2 55 are meshed with each other, and the rack 2 55 slides in the side wall groove of the installation box 4. The output end of the gear 1 54 is connected to the gear 2 56, and the damping between the gear 1 54 and the gear 2 56 The number of teeth of gear 1 54 is smaller than that of gear 2 56, gear 2 56 rotates on the inner wall of mounting box 4, gear 2 56 meshes with rack 3 57, rack 3 57 slides in the side wall groove of mounting box 4, the filtration hole density of first filter plate 58 is smaller than that of second filter plate 59, the filtration hole density of second filter plate 59 is smaller than that of third filter plate 510, the first filter plate 58, the second filter plate 59 and the third filter plate 510 slide on the inner side of mounting box 4 respectively, one side of the second filter plate 59 is connected to rack 2 55, and one side of the third filter plate 510 is connected to rack 3 57; By setting the filter assembly 5, the operator first fills the industrial wastewater into the wastewater tank 3, and controls the cylinder 52 to push the gate 51 through the control module (marked in the figure), so that the industrial wastewater enters the interior of the installation box 4 through the opening and closing gap of the gate 51 and contacts the first filter plate 58. In the initial state, the first filter plate 58 is always in the installation box 4. When the gate 51 slides outwardly by half of the gap in the slide groove of the installation box 4, it drives the rack 1 53 to slide on the inner side of the installation box 4, and the rack 1 53 and the gear 1 54 are meshed with each other, so that the rack 2 55 is meshed with the gear 1 54 and slides in the opposite direction of the rack 1 53. The rack 2 55 drives the second filter plate 59 to move toward the inner side of the installation box 4, so that the second filter plate 59 is clamped in the interior of the installation box 4 to perform secondary filtration on the wastewater. When the gate 51 is fully opened, the gear 1 54 rotates. The gear 2 56 is driven to rotate with damping, and the gear 2 56 is meshed with the rack 3 57 to drive the third filter plate 510 to move inside the installation box 4 to perform three-stage filtration on the wastewater. Since the number of teeth of the gear 2 56 is greater than the number of teeth of the gear 1 54, and the gear 1 54 is connected to the gear 2 56 by damping, the second filter plate 59 and the third filter plate 510 will not move synchronously. By controlling the flow rate of industrial wastewater, filter layers of different fineness are used to avoid the situation that when the flow rate is too large, only one filter layer cannot completely filter out the iron filings impurities in the industrial wastewater. The flow rate of industrial wastewater is controlled by the opening and closing size of the gate 51, and through the transmission between the gear and the rack, filter layers of different fineness are used to avoid the situation that when the flow rate is too large, only one filter layer is used for filtering, and iron filings impurities are gathered in one area, blocking the filter layer and resulting in low filtration efficiency.

[0042] like Figures 5 to 11As shown, the scraping assembly 6 includes a mounting frame 61, which is evenly distributed and installed on the outside of the mounting box 4. The mounting frame 61 is provided with three groups, and two reciprocating screw rods 62 are installed on the inner side of each group of mounting frames 61. A slider 63 is sleeved on the outer side of each reciprocating screw rod 62. The two sliders 63 on each group of mounting frames 61 are initially arranged relative to each other. A slide bar 64 is nested on the inner side of the slider 63. The slider 63 slides on the outer side of the slide bar 64. A permanent magnet 65 is connected to the outer side of the slider 63. The bottom of the mounting frame 61 is connected to a scraper 66 through a torsion spring. The contact end of the plate 66 is provided with a contact block 67, which is made of rubber material. The tail end of the reciprocating screw rod 62 is connected with a gear 3 68, which meshes with a rack 4 69. The rack 4 69 is evenly distributed in three groups, which are respectively installed on one side of the first filter plate 58, the second filter plate 59 and the third filter plate 510. One end of each group of mounting frames 61 is connected with a cleaning block 610, which is made of rubber material. A cylindrical contact head is provided on the surface of the cleaning block 610 for scraping off iron filings adsorbed on the surface of the permanent magnet 65. By providing the scraping assembly 6, at the end of filtering, the operator pulls out the first filter plate 58, the second filter plate 59 and the third filter plate 510 in sequence to move the corresponding rack four 69, and the rack four 69 and the corresponding two gear three 68 are meshed with each other, so that the reciprocating screw rod 62 rotates on the inner side of the mounting frame 61, and the slider 63 drives the permanent magnet 65 to slide back and forth under the limit of the slide rod 64. The initial positions of the two permanent magnets 65 are relatively set, and the permanent magnets 65 respectively contact the relative The scrapers 66 are respectively at the bottom of the corresponding filter plates, and the scrapers 66 are always in close contact with the bottom of the filter plates through the action of the torsion springs. The contact blocks 67 are in contact with the bottom of the corresponding filter plates. When the contact blocks 67 come into contact with the scrap iron, they flip downwards and are reset by the torsion springs to push the adhering scrap iron upwards. At the same time, the contact blocks 67 are The vibration force generated by the reset block 67 hitting the bottom surface of the filter plate prevents the iron filings from being adsorbed on the surface of the filter plate by the viscosity of the wastewater, and then being adsorbed by the permanent magnet 65. When the end of the reciprocating screw 62 of the slider 63 moves, the permanent magnet 65 contacts the cleaning block 610 made of rubber material, and contacts with multiple groups of cylindrical contact heads of the cleaning block 610 to sweep away the iron filings adsorbed on the surface of the permanent magnet 65. The iron filings are moved by the reciprocating contact of the permanent magnet 65 to move the cleaning block 610 and fall into the collection tank 10. The second filter plate 59 and the third filter plate 510 can collect iron filings and impurities through the opening and closing action of the gate 51, so that the corresponding permanent magnets 65 can collect iron filings and impurities to avoid clogging and failure of the filter plates. The contact block 67 resets and knocks on the bottom surface of the filter plate to generate a vibration force, so that the iron filings and impurities will not be adsorbed on the surface of the filter plate through the viscosity of the wastewater, and then adsorbed by the permanent magnet 65, so that the iron filings will not stick to the surface of the filter plate and cannot be removed. The upper suction and lower push method is used to improve the efficiency of iron filing treatment and avoid the accumulation of iron filings and impurities on the surface of the filter plate.

[0043] like Figure 12 to Figure 13 As shown, the anti-corrosion component 7 includes a filling pipe 71, which is installed on the inner side of the mounting frame 61, and a piston 72 is nested on the inner side of the filling pipe 71. The piston 72 slides on the inner side of the filling pipe 71, and the end of the piston 72 is connected to a connecting rod 73, and the connecting rod 73 is connected to one side of the slider 63. A one-way valve 1 74 is connected to one side of the filling pipe 71, and the end of the one-way valve 1 74 is connected to the brush holder 75 through a pipeline. A one-way valve 2 76 is connected to one side of the filling pipe 71, and the end of the one-way valve 2 76 is connected to the storage barrel 77 through a pipeline. By providing the anti-corrosion component 7, when one of the sliders 63 on the mounting frame 61 slides on the corresponding reciprocating screw rod 62, it drives the connecting rod 73 to move, so that the piston 72 squeezes the oil inside the filling pipe 71, and the oil enters the brush holder 75 through the one-way valve 74 and the pipeline. The oil wets the brush part of the brush holder 75, so that in the process of pulling out the first filter plate 58, the second filter plate 59 and the third filter plate 510, the brush part contacts the frame connectors in the corresponding first filter plate 58, the second filter plate 59 and the third filter plate 510 respectively, and the anti-corrosion protective oil is applied to prevent the filter plate connectors from being in contact with wastewater for a long time. The contact causes a jam, resulting in the first filter plate 58, the second filter plate 59 and the third filter plate 510 being unable to be pulled out. When the slider 63 slides in the opposite direction on the reciprocating screw 62, the piston 72 is pulled by the connecting rod 73 and moves in the opposite direction in the filling pipe 71. The negative pressure generated will cause the oil in the storage barrel 77 to enter the inner side of the filling pipe 71 through the pipeline and the one-way valve 2 76. Since the one-way valve 1 74 has unidirectional conductivity, the oil in the brush holder 75 will not be sucked back into the filling pipe 71, thereby avoiding the filter plate connector from being in contact with the wastewater for a long time and causing jam, resulting in the inability to clean the filter plate after the sewage treatment is completed, affecting the service life of the device.

[0044] The working principle of the technical solution provided by the present invention is as follows: The operator first fills the industrial wastewater into the wastewater tank 3, and controls the cylinder 52 to push the gate 51 through the control module (marked in the figure), so that the industrial wastewater enters the interior of the installation box 4 through the opening and closing gap of the gate 51 and contacts the first filter plate 58. In the initial state, the first filter plate 58 is always in the installation box 4. When the gate 51 slides outwardly by half of the gap in the slide groove of the installation box 4, it drives the rack 1 53 to slide on the inner side of the installation box 4, and the rack 1 53 and the gear 1 54 are meshed with each other, so that the rack 2 55 is meshed with the gear 1 54 and slides in the opposite direction of the rack 1 53, and the rack 2 55 drives the second filter plate 59 to move toward the inner side of the installation box 4, so that the second filter plate 59 is moved to the inner side of the installation box 4. The filter plate 59 is clamped inside the installation box 4 to perform secondary filtration on the wastewater. When the gate 51 is fully opened, the gear 1 54 rotates to drive the gear 2 56 to rotate with damping. The gear 2 56 meshes with the rack 3 57 to drive the third filter plate 510 to move inside the installation box 4 to perform tertiary filtration on the wastewater. Since the number of teeth of the gear 2 56 is greater than the number of teeth of the gear 1 54, and the gear 1 54 is connected to the gear 2 56 through damping, the second filter plate 59 and the third filter plate 510 will not move synchronously. By controlling the flow rate of industrial wastewater, filter layers of different fineness are used to avoid the situation that when the flow rate is too large, only one filter layer cannot completely filter out iron filings and impurities in the industrial wastewater. At the end of filtration, the operator pulls out the first filter plate 58, the second filter plate 59 and the third filter plate 510 in sequence to move the corresponding rack four 69, and the rack four 69 meshes with the corresponding two gear three 68, so that the reciprocating screw rod 62 rotates on the inner side of the mounting frame 61, and the slider 63 drives the permanent magnet 65 to slide back and forth under the limit of the slide rod 64. The initial positions of the two permanent magnets 65 are relatively set, and the permanent magnets 65 respectively absorb the iron filings and impurities adsorbed on the surfaces of the corresponding first filter plate 58, the second filter plate 59 and the third filter plate 510. At the same time, in the process of pulling out the first filter plate 58, the second filter plate 59 and the third filter plate 510, the scraper 66 is respectively at the bottom of the corresponding filter plate, and the scraper 66 is always tightly attached to the bottom surface of the filter plate through the action of the torsion spring, and the contact block 67 is with the corresponding filter plate The bottom surface contacts, when the contact block 67 contacts with the iron filings, it flips downwards and is reset by the torsion spring to push the adhered iron filings upwards. At the same time, the vibration force generated by the contact block 67 resetting and knocking the bottom surface of the filter plate prevents the iron filings from being adsorbed on the filter plate surface by the viscosity of the wastewater, and then adsorbed by the permanent magnet 65. When the end of the reciprocating screw rod 62 of the slider 63 moves, the permanent magnet 65 contacts the cleaning block 610 made of rubber material, and contacts with multiple groups of cylindrical contact heads of the cleaning block 610 to sweep away the iron filings adsorbed on the surface of the permanent magnet 65. The iron filings are moved by the reciprocating contact of the permanent magnet 65 to move the cleaning block 610 and fall into the collection tank 10. The second filter plate 59 and the third filter plate 510 can collect the iron filings and impurities through the opening and closing action of the gate 51, so as to avoid the filter plate from being blocked and failing. When one of the sliders 63 on the mounting frame 61 slides on the corresponding reciprocating screw rod 62, it drives the connecting rod 73 to move, so that the piston 72 squeezes the oil inside the filling pipe 71, and the oil enters the brush holder 75 through the one-way valve 74 and the pipeline. The oil wets the brush part of the brush holder 75, so that in the process of pulling out the first filter plate 58, the second filter plate 59 and the third filter plate 510, the brush part contacts the frame connectors in the corresponding first filter plate 58, the second filter plate 59 and the third filter plate 510 respectively, and the anti-corrosion is applied. The corrosion protection oil is used to prevent the filter plate connector from being stuck due to long-term contact with wastewater, which makes the first filter plate 58, the second filter plate 59 and the third filter plate 510 unable to be pulled out. When the slider 63 slides in the opposite direction on the reciprocating screw rod 62, the piston 72 is pulled by the connecting rod 73 and moves in the opposite direction in the filling pipe 71. The negative pressure generated causes the oil in the storage barrel 77 to enter the inner side of the filling pipe 71 through the pipeline and the one-way valve 76. Since the one-way valve 74 has unidirectional conductivity, the oil in the brush holder 75 will not be sucked back into the filling pipe 71. After the industrial wastewater is filtered in the installation box 4 to remove iron filings and impurities, it enters the evaporation treatment tank 8 through a pipeline for treatment.
