Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and more specifically, to a dyeing and printing wastewater sludge treatment device with backwashing function. Background Technology

[0002] Dyeing and printing wastewater mainly originates from the dyeing and finishing processes of cotton, linen, chemical fibers and their blended fabrics, as well as silk and wool fabrics. This includes wastewater discharged from multiple processes such as desizing, scouring, bleaching, mercerizing, dyeing, printing, and finishing. This wastewater is characterized by its complex and diverse composition, deep color, strong alkalinity, difficulty in biochemical treatment, and significant fluctuations in water quality. The pollutants contained in dyeing and printing wastewater are numerous and complex, mainly including colored wastewater containing salt and organic matter; chlorinated and brominated wastewater; organic wastewater containing slightly acidic and slightly alkaline substances; colored wastewater containing cations such as copper, lead, chromium, manganese, and mercury; and sulfur-containing organic wastewater. Therefore, dyeing and printing wastewater sludge treatment equipment is an important component of the dyeing and printing wastewater treatment system, used to treat the sludge generated during the dyeing and printing wastewater treatment process, reducing its environmental pollution risk, and ensuring that the final disposal of the sludge meets environmental protection requirements.

[0003] Existing solid-liquid separation equipment is prone to clogging of filter plates due to the large amount of impurities. This requires frequent cleaning of the sludge inside the device, which is labor-intensive, inefficient, and inconvenient for users.

[0004] A search revealed that Chinese patent CN211069264U discloses an environmentally friendly dyeing and printing wastewater sludge treatment device. By setting a spring, tension is generated on the movable rod, causing the movable rod to push the first brush plate into close contact with the inner wall of the filter barrel, which can better clean the impurities on the inner wall of the filter barrel. By setting a second brush plate, impurities on the surface of the filter barrel can be cleaned. By setting a first sealing sleeve, the sealing between the discharge pipe and the box body is enhanced. By setting a second sealing sleeve, the sealing between the movable rod and the horizontal pipe is enhanced.

[0005] In actual use, the above-mentioned environmentally friendly dyeing and printing wastewater sludge treatment device continuously intercepts impurities such as suspended solids, fibers, and dye particles in the wastewater during the dyeing and printing wastewater sludge treatment process. These impurities gradually accumulate on the surface and inside of the filter barrel, forming a thick filter cake layer, which leads to a sharp increase in filtration resistance and a significant reduction in the flow rate of wastewater through the filter barrel. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dyeing and printing wastewater sludge treatment device with backwashing function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dyeing and printing wastewater sludge treatment device with backwashing function includes a shell, a drain pipe connected to one side of the shell, a cover plate installed at the top of the shell, a feed pipe connected to the top of the cover plate, and a backwashing component and a mixing mechanism installed inside the shell, with the mixing mechanism installed on one side of the backwashing component.

[0009] The backwashing assembly includes a water pump mounted on the top of a cover plate. Both the pump's output and input ends are connected to a connecting pipe. One end of one of the connecting pipes is connected to a flow divider ring, which is installed inside the cover plate. The bottom end of the flow divider ring is connected to multiple connecting pipes, the bottom end of which is connected to a spray pipe. Two support frames are fixedly connected to the outside of the spray pipe, and multiple nozzles are connected to the outside of the spray pipe. First scrapers are fixedly connected to both sides of the support frames. A first servo motor is mounted on one side of the outer casing. A gear is fixedly connected to the output end of the first servo motor. A gear plate meshes with one side of the gear. A slip ring is fixedly connected to the bottom end of the gear plate. A support ring is provided on the outside of the slip ring. The support ring is fixedly connected to the inside of the outer casing, and the slip ring is slidably connected to the inside of the support ring. A first filter barrel is fixedly connected to the inside of the gear plate, and a second filter barrel is fixedly connected to the inside of the first filter barrel.

[0010] By adopting the above technical solution, the first and second filter barrels after filtration can be effectively cleaned, and the sludge caking on the surface of the first and second filter barrels can be reduced.

[0011] As a further description of the above technical solution: the mixing mechanism includes a second servo motor, which is installed inside the second filter barrel. A rotating rod is fixedly connected to the output end of the second servo motor. A support rod is fixedly connected to the outside of the rotating rod. Multiple second scrapers are fixedly connected to the top of the support rod. A spiral blade is fixedly connected to the outside of the rotating rod.

[0012] By adopting the above technical solution, the flow of wastewater can be accelerated, and the inner wall of the second filter barrel can be scraped to reduce the adhesion of sludge.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up a backwashing component, compared with the existing technology, by driving the first filter barrel and the second filter barrel to rotate, multiple first scrapers and nozzles can clean the rotating first filter barrel and the second filter barrel. The centrifugal force generated by the rotation and the impact force of the backwash water flow form a force that can enhance the sludge removal effect, thereby reducing sludge caking on the surface of the first filter barrel and the second filter barrel and extending the effective filtration cycle of the first filter barrel and the second filter barrel.

[0015] 2. By setting up a mixing mechanism, compared with the existing technology, the rotation of the spiral blades causes the wastewater to generate vortex, which can drive the wastewater to flow and accelerate the wastewater to pass through the second filter barrel. Multiple second scrapers can scrape the inside of the second filter barrel, which can remove the filter residue trapped on the second filter barrel in real time, reduce the accumulation of sludge that leads to a decrease in filtration efficiency, maintain the stable filtration performance of the second filter barrel, and ensure the smooth progress of the treatment process.

[0026] The backwashing assembly includes a water pump 5, which is mounted on the top of the cover plate 3. Both the output and input ends of the water pump 5 are connected to a connecting pipe 6. One end of one connecting pipe 6 is connected to a diverter ring 7, which is installed inside the cover plate 3. The bottom end of the diverter ring 7 is connected to multiple connecting pipes 8, and the bottom end of each connecting pipe 8 is connected to a spray pipe 9. Two support frames 10 are fixedly connected to the outside of the spray pipe 9, and multiple nozzles 11 are connected to the outside of the spray pipe 9. First scrapers 12 are fixedly connected to both sides of each support frame 10. A first servo motor 13 is mounted on one side of the outer casing 1. A gear 14 is fixedly connected to the output end of the first servo motor 13. A gear 15 meshes with one side of the gear 14. A slip ring 16 is fixedly connected to the bottom end of the gear 15. A support ring 17 is provided on the outside of the slip ring 16. The support ring 17 is fixedly connected to the inside of the outer casing 1, and the slip ring 16 is slidably connected to the inside of the support ring 17. A first filter barrel 18 is fixedly connected to the inner side of the gear disc 15, and a second filter barrel 19 is fixedly connected to the inner side of the first filter barrel 18. The gear 14 meshes and drives the gear disc 15 to rotate, so that the first filter barrel 18 and the second filter barrel 19 can rotate inside the outer shell 1. The slip ring 16 and the support ring 17 are slidably connected, so that the gear disc 15 can rotate stably. At the same time, under the action of the water pump 5, water can be delivered to the diversion ring 7. The diversion ring 7 can deliver water to multiple spray pipes 9, so that multiple first scrapers 12 can spray the rotating first filter barrel 18 and the second filter barrel 19. At the same time, two nozzles 11 can scrape the first filter barrel 18 and the second filter barrel 19, thereby reducing the sludge caking on the filter screen surface and helping to extend the effective filtration cycle of the first filter barrel 18 and the second filter barrel 19.

[0027] Reference Figure 6 As shown, the mixing mechanism includes a second servo motor 21, which is installed inside the second filter barrel 19.

The rotating rod 22 drives the multiple second scrapers 24 and the spiral blade 25 to rotate. The spiral action of the spiral blade 25 can accelerate the rotation of wastewater inside the second filter barrel 19, thereby accelerating the filtration efficiency. The multiple second scrapers 24 can scrape the inside of the second filter barrel 19, which can remove the filter residue trapped on the second filter barrel 19 in real time, thereby reducing the adhesion of sludge and enabling the second filter barrel 19 to maintain stable filtration performance.

[0028] Working principle of this utility model: This utility model designs a dyeing and printing wastewater sludge treatment device with backwashing function, and the specific structure is shown in the attached instruction manual. Figure 1-7 As shown, in this technical solution, through the cooperation of various structures, when the dyeing and printing wastewater needs to be treated, the pre-treated wastewater is first transported to the inside of the outer shell 1 through the feed pipe 4. The second filter barrel 19 performs initial filtration of the wastewater, filtering out larger impurities. The second servo motor 21 is then activated, driving the rotating rod 22 to rotate. This rotating rod 22 drives the support rod 23 and the spiral blades 25 to rotate. The support rod 23 drives multiple second scrapers 24 to scrape the inner wall of the second filter barrel 19, and the spiral action of the spiral blades 25 generates vortices, facilitating the flow of wastewater inside the second filter barrel 19 and accelerating the filtration rate. Subsequently, the wastewater is filtered again through the first filter barrel 18. The wastewater that has passed through the impurity filter flows into the inside of the outer shell 1 and is discharged through the drain pipe 2. When backwashing of the first filter barrel 18 and the second filter barrel 19 is required, the water pump 5 is started, and one of the connecting pipes 6 is connected to the external water pipe. Under the action of the water pump 5, water can be delivered to the inside of the diversion ring 7. The diversion ring 7 can deliver water to multiple spray pipes 9 through the connecting pipe 8, so that multiple first scrapers 12 can spray and clean the inside of the first filter barrel 18 and the outside of the second filter barrel 19 at the same time. The first servo motor 13 is started, and the first servo motor 13 drives the gear 14 to rotate, so that the gear 14 meshes and drives the gear plate 15 to rotate. The gear plate 15 can rotate above the support ring 17 through the slip ring 16, so that the gear plate 15 can drive the first filter barrel 18 to rotate, so that the first filter barrel 18 and the second filter barrel 19 can rotate for spray cleaning, thereby cleaning the first filter barrel 18 and the second filter barrel 19.
