Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater purification technology, specifically to a high-efficiency industrial wastewater purification and treatment device. Background Technology

[0002] Industrial wastewater refers to wastewater, sewage, and waste liquid generated during industrial production. Originating from industrial production, industrial wastewater mainly includes: process water: water used in production processes such as reactions, cooling, and washing carries pollutants and becomes wastewater, such as cooling water absorbing impurities in chemical production; equipment cleaning water: wastewater containing pollutants generated after equipment operation, such as wastewater containing food residue and grease from equipment cleaning in food processing plants; and site flushing water: wastewater containing pollutants generated from the regular flushing of production sites, such as wastewater containing dust and ore fragments generated from washing the ground in mining areas. In the wastewater pretreatment stage, filtration is a crucial step in removing suspended solids and larger particulate impurities from wastewater. However, many traditional filtration devices suffer from low filtration efficiency and are prone to clogging. When the suspended solids content in the wastewater is high, the filter screen quickly becomes clogged, leading to a decrease in filtration speed and requiring frequent shutdowns for cleaning or replacement of the filter screen, affecting the continuity and efficiency of wastewater treatment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 3This utility model provides a technical solution: a high-efficiency industrial wastewater purification device, comprising: a support frame 1; a wastewater pipe 7 positioned above the support frame 1; connecting pipes 5 equidistantly fixed to the bottom of the wastewater pipe 7, with a connecting water pipe 4 at the bottom end of the connecting pipe 5; a diversion pipe 14 positioned at the bottom end of the connecting water pipe 4; a mounting cover 3 fixed to the outside of the diversion pipe 14; multiple first connecting cylinders 2 equidistantly fixed inside the support frame 1, the first connecting cylinders 2 and the mounting cover 3 being installed by bolts; a filter screen barrel 13 fixed inside the first connecting cylinder 2, with a diversion pipe 14 at the bottom end of the connecting water pipe 4, and a diversion pipe 14 opening at the top of the filter screen barrel 13. The filter screen 13 has an insertion hole for the flow insertion tube 14; the inner rotating rod 16 is rotatably set inside the filter screen 13, and the outer side of the inner rotating rod 16 is symmetrically fixed with an inner scraper 15 that cooperates with the filter screen 13; the outlet pipe 10 is symmetrically fixed to the bottom of the mounting cover 3, and the bottom end of the outlet pipe 10 is fixed to the connecting water tank 12; the central pipe 17 is fixed to the bottom of the connecting water tank 12; the mixing component is placed below the central pipe 17 and connected to the central pipe 17; the diversion insertion tube 14 is inserted into the insertion hole opened at the top of the filter screen 13, and industrial wastewater is injected into the filter screen 13 through the connecting water pipe 4 and the diversion insertion tube 14, and the industrial wastewater is filtered through the filter screen 13.

[0027] The mixing assembly includes a mixing tank 20, which is located below the central pipe 17. A main connecting pipe 18 is fixedly connected to the top of the mixing tank 20, and the top end of the main connecting pipe 18 is connected to the central pipe 17. An agitator 21 is rotatably installed inside the mixing tank 20. A second motor 22 is installed on the top of the mixing tank 20, and the output end of the second motor 22 is fixedly connected to the agitator 21. The output end of the second motor 22 drives the agitator 21 to rotate. When the agitator 21 rotates, it mixes the flocculant and industrial wastewater in the mixing tank 20, which facilitates the flocculation treatment of the wastewater.

[0028] The main connecting pipe 18 is equipped with a flow sensor 19, a feed pipe 23 is provided on one side of the mixing tank 20, and a drain pipe 24 is provided on one side of the mixing tank 20. The feed pipe 23 facilitates the addition of flocculant into the mixing tank 20, and the flow sensor 19 monitors and processes the water flow rate flowing through the main connecting pipe 18.

[0029] The bottom of the mounting cover 3 is fixedly connected to a bottom fixing frame 8. A motor 11 is installed inside the bottom fixing frame 8. The output end of the motor 11 is fixedly connected to the inner rotating rod 16. The inner rotating rod 16 is rotatably connected to the bottom fixing frame 8. The output end of the motor 11 drives the inner rotating rod 16 to rotate. When the inner rotating rod 16 rotates, it drives the outer inner scraper 15 to rotate. The inner scraper 15 scrapes away the impurities filtered inside the filter screen barrel 13.

[0030] The bottom of the filter screen barrel 13 is symmetrically equipped with bottom sealing seats 9 by bolts. The bottom sealing seats 9 are installed at the bottom of the filter screen barrel 13 by bolts. Removing the bottom sealing seats 9 makes it convenient to clean the impurities inside the filter screen barrel 13.

[0031] The connecting pipe 5 is equipped with a solenoid valve 6, which allows for convenient control of the sewage flow status of the connecting pipe 5.

[0032] Specifically, during use, industrial wastewater is introduced into one of the connecting pipes 5 through the wastewater inlet pipe 7, then into the connecting water pipe 4 through the connecting pipe 5, and finally into the filter screen barrel 13 through the diversion pipe 14. The industrial wastewater is filtered through the filter screen barrel 13. The output end of the first motor 11 drives the inner rotating rod 16 and the inner scraper 15 to rotate. The inner scraper 15 scrapes away the impurities filtered inside the filter screen barrel 13 to prevent clogging. The filtered industrial wastewater enters the connecting water tank 12 through the outlet pipe 10, then enters the central pipe 17 through the connecting water tank 12, and finally enters the main connecting pipe 18 through the central pipe 17. The flow rate is monitored by the flow sensor 19. The filtered wastewater enters the mixing tank 20 through the main connecting pipe 18. Flocculant is added to the mixing tank 20 through the feed pipe 23. The output end of the second motor 22 drives the stirring shaft 21 to rotate, mixing the wastewater and flocculant. The wastewater is then discharged through the drain pipe 24. The mixed wastewater in the mixing tank 20 is discharged to the sedimentation tank through the drain pipe 24. The flocculated wastewater needs to enter the sedimentation tank for solid-liquid separation. In the sedimentation tank, the flocculent will settle at the bottom to form sludge, while the upper part is clean water. Then, the wastewater is further filtered to remove suspended solids and impurities. The supernatant after sedimentation usually needs to be filtered. The filtration device can use sand filtration, activated carbon filtration, or membrane filtration to improve the clarity of the wastewater. By removing the bolts connecting the bottom sealing seat 9 and the first connecting cylinder 2, the bottom sealing seat 9 can be removed, and the impurities in the filter screen 13 can be cleaned and removed. By setting the flow sensor 19, the flow sensor 19 can detect the water flow of the central pipe 17 and the main connecting pipe 18. When the filter screen 13 in the first connecting cylinder 2 is blocked, the filter screen 13 in the other connecting cylinder 2 can be opened to filter the industrial wastewater, which facilitates the cleaning of the large amount of impurities accumulated in the filter screen 13.
