Description

TECHNICAL FIELD

[0001] The present application relates to the field of printing and dyeing wastewater treatment, in particular to a printing and dyeing wastewater treatment device with multi-stage separation function. BACKGROUND

[0002] When the printing and dyeing wastewater is subjected to multi-stage separation, the sedimentation tank is relatively simple in structure and low in operation cost, and it is usually used as a preliminary treatment step to remove a considerable part of pollutants in the wastewater at a low cost. This treatment method of first easy and then difficult, first rough and then fine conforms to the principle of economic efficiency. For example, compared with some advanced oxidation treatment technology or deep filtration technology, the construction and operation cost of the sedimentation tank is lower, but it can achieve effective separation of a large amount of suspended impurities.

[0003] In the process of separating the printing and dyeing wastewater, the traditional sedimentation tank mainly relies on gravity sedimentation to let the suspended particles settle naturally. For some small particles, colloids or emulsified pollutants, the sedimentation effect is poor. These substances are difficult to settle at the bottom for a long time, resulting in a long sedimentation time to achieve a certain treatment effect. In addition, in the actual production process, the flow and water quality of the printing and dyeing wastewater will affect the sedimentation effect, making the effluent water quality unstable. Moreover, the traditional sedimentation tank passively waits for the sedimentation of pollutants without actively promoting the sedimentation process by physical means. If the pollutant particles in the wastewater are small or have the same charge, they will repel each other and it is difficult for them to naturally aggregate and settle. In this case, the traditional sedimentation tank cannot effectively accelerate the sedimentation process.

[0004] In the printing and dyeing production process, in order to improve the sedimentation effect, the traditional method often needs to add a large amount of chemical agents or prolong the sedimentation time. Adding chemical agents not only increases the treatment cost, but also introduces new pollutants. In actual production, the long sedimentation time cannot meet the production schedule requirements, resulting in that the wastewater cannot be treated and discharged in a timely manner.

[0005] In the traditional sedimentation tank, if there is no effective anti-clogging measure, the settled floating materials will accumulate at the filter screen disc as the drainage process continues. These floating materials will gradually clog the pores of the filter screen disc, causing the drainage speed to slow down. When the filter screen disc is seriously clogged, manual cleaning is required, which not only wastes time and effort, but also affects the continuity of the entire wastewater treatment process during the cleaning period. Moreover, the cleaning of the filter screen disc in the traditional sedimentation tank is usually carried out by periodic manual inspection and cleaning, which cannot respond to the clogging problem of the filter screen disc in real time. Because the time interval between two cleanings is relatively long, the clogging of the filter screen disc has a negative impact on the drainage and treatment process during the interval.

[0006] Therefore, it is necessary to provide a printing and dyeing wastewater treatment device with multi-stage separation function to solve the above problems. SUMMARY

[0007] In view of the deficiencies of the prior art, the present application aims to provide a printing and dyeing wastewater treatment device with multi-stage separation function.

[0008] To achieve the above object, the present application provides the following technical solution: a printing and dyeing wastewater treatment device with multi-stage separation function, comprising a sedimentation tank, an auxiliary separation assembly for assisting the sedimentation of printing and dyeing wastewater is arranged on the top of the sedimentation tank, an amplitude adjustment assembly for adjusting the sliding amplitude of the auxiliary separation assembly is arranged above the sedimentation tank, and an anti-blocking assembly for ensuring smooth drainage is arranged inside the sedimentation tank.

[0009] Preferably, the auxiliary separation assembly comprises a positioning frame fixedly connected to the top of the sedimentation tank, a driving device fixedly connected to the top of the positioning frame, a driving rod fixedly connected to the output shaft end of the driving device, a rotating groove opened at the bottom of the driving rod, and a rotating disc rotatably connected to the outside of the rotating groove.

[0010] Preferably, the auxiliary separation assembly further comprises a limiting strip fixedly connected to the top of the driving rod, a connecting disc slidingly connected to the outer wall of the limiting strip, a connecting rod rotatably connected to the bottom of the connecting disc, and an end of the connecting rod away from the connecting disc rotatably connected to the top of the rotating disc.

[0011] Preferably, the amplitude adjustment assembly comprises an amplitude increasing block fixedly connected to the top of the positioning frame, a threaded rod threadedly rotatably connected to the inside of the amplitude increasing block, a rotating handle fixedly connected to the top of the threaded rod, and a double-layer chuck fixedly connected to the bottom of the threaded rod.

[0012] Preferably, the anti-blocking assembly comprises a drainage groove opened in the inside of the sedimentation tank, a sealing plug arranged on the side of the drainage groove away from the sedimentation tank, and a filter disc clamped in the inside of the drainage groove.

[0013] Preferably, the anti-blocking assembly further comprises a positioning block fixedly connected to the inside of the drainage groove, a power conversion wheel rotatably connected to the center of the positioning block, and a triangular scraping rod fixedly connected to an end of the power conversion wheel close to the positioning block.

[0014] Preferably, the driving rod is rotatably connected to the inside of the positioning frame, and the connecting disc is slidingly connected to the top of the driving rod.

[0015] Preferably, the bottom ball of the spherical limiting rod is provided with a hollow core, and an end of the connecting rod away from the spherical limiting rod is arranged in the inside of the rotating disc.

[0016] Preferably, the double-layer chuck is arranged inside the adapter disc.

[0017] Preferably, the three strip-shaped scraping blades of the triangular scraping rod are annularly distributed at the end of the triangular scraping rod away from the power conversion wheel, and the three strip-shaped scraping blades of the triangular scraping rod are all arranged in an inclined shape.

[0018] Compared with the prior art, the printing and dyeing wastewater treatment device with multi-stage separation function has the following beneficial effects:

[0019] 1. By means of the auxiliary separation assembly and the amplitude adjusting assembly, the driving rod can drive the driving disc to rotate, the driving disc can drive the adapter rod to move vertically and reciprocally, and finally the spherical limiting rod can continuously beat the precipitated printing and dyeing wastewater, so that the continuous beating action can produce regular physical disturbance in the wastewater, which is different from the passive precipitation mode of the traditional sedimentation tank, and can actively break the stable state of the pollutants in the wastewater.

[0020] Secondly, when the ball of the spherical limiting rod contacts the wastewater, it can cause local water flow fluctuation and pressure change, just like making oil droplets gather and float in sesame oil, so that the pollutants in the printing and dyeing wastewater can be better gathered and precipitated, and through the continuous physical disturbance, the device can make the pollutants in the printing and dyeing wastewater complete precipitation in a short time, which greatly improves the precipitation efficiency and shortens the residence time of the wastewater in the sedimentation tank, thereby improving the treatment capacity of the entire printing and dyeing wastewater treatment system.

[0021] Finally, the position of the adapter disc can be adjusted by the double-layer chuck through the rotation of the threaded rod, the offset amplitude of the driving disc can be adjusted by the adapter disc through the connecting rod, the beating frequency and intensity of the spherical limiting rod can be actively controlled, the changes of the quality and flow of the printing and dyeing wastewater can be better coped with, and no matter how the concentration and particle size of the pollutants in the wastewater change, the parameters of the beating action can be adjusted to effectively promote precipitation and ensure the stability of the effluent quality, which is difficult to achieve by the traditional sedimentation tank.

[0022] 2. By setting up anti-clogging components, during the collection of effluent, the settled water flows out through the drainage channel. At this time, the flowing water drives the power conversion wheel to rotate, converting water energy into mechanical energy. Finally, the power conversion wheel drives the triangular scraper to clean the surface of the filter screen, preventing the filter screen from being blocked by settled floating matter during drainage. This reduces the additional power input requirement. For example, during long-term operation, the water flow itself drives the triangular scraper to clean the filter screen, eliminating the need for a separate motor or other power equipment for scraper cleaning, thereby reducing the operating cost of the entire sewage treatment system.

[0023] Secondly, by utilizing the automatic cleaning mechanism of the power conversion wheel and triangular scraper driven by water flow, real-time cleaning is achieved during the drainage process. As long as water flows through the drainage channel, the scraper will continuously clean the filter screen, ensuring the filter screen is in good working condition. This automated operation mode reduces the need for manual intervention, improves the automation level and operational stability of the entire sewage treatment system, and enables the sedimentation tank to operate more continuously and stably.

[0037] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples, and it should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0039] The specific implementation of the present application is described in detail below in combination with specific examples.

[0040] The implementation example is as follows: Figures 1 to 9 As shown in the drawings, the printing and dyeing wastewater treatment device provided by an embodiment of the present application has a multi-stage separation function, comprising a sedimentation tank 11, the top of the sedimentation tank 11 is provided with an auxiliary separation assembly for assisting the sedimentation of the printing and dyeing wastewater, the upper part of the sedimentation tank 11 is provided with an amplitude adjustment assembly for adjusting the sliding amplitude of the auxiliary separation assembly, and the inside of the sedimentation tank 11 is provided with an anti-blocking assembly for ensuring smooth drainage.

[0041] The auxiliary separation assembly comprises a positioning frame 21, the positioning frame 21 is fixedly connected to the top of the sedimentation tank 11, the top of the positioning frame 21 is fixedly connected with a driving device 22, the output shaft end of the driving device 22 is fixedly connected with a driving rod 23, the bottom of the driving rod 23 is provided with a rotating groove 24, and the outer side of the rotating groove 24 is rotatably connected with a dial plate 25.

[0042] The auxiliary separation assembly further comprises a limiting strip 26 fixedly connected to the top of the driving rod 23, an outer wall of the limiting strip 26 being slidingly connected with an adapter disc 27, the bottom of the adapter disc 27 being rotatably connected with a connecting rod 28, one end of the connecting rod 28 away from the adapter disc 27 being rotatably connected to the top of the dial disc 25, one end of the positioning frame 21 away from the sedimentation tank 11 being slidingly connected with a spherical limiting rod 29, and an outer wall of the spherical limiting rod 29 being fixedly connected with an adapter rod 210.

[0043] The amplitude adjustment assembly comprises an increased distance block 31 fixedly connected to the top of the positioning frame 21, a threaded rod 32 threadedly rotatably connected to the inside of the increased distance block 31, a rotating handle 33 fixedly connected to the top of the threaded rod 32, and a double-layer chuck 34 fixedly connected to the bottom of the threaded rod 32.

[0044] The anti-blocking assembly comprises a drainage groove 41 formed in the inside of the sedimentation tank 11, a sealing plug 42 provided on one side of the drainage groove 41 away from the sedimentation tank 11, and a filter screen disc 43 clamped in the inside of the drainage groove 41.

[0045] The anti-blocking assembly further comprises a positioning block 44 fixedly connected to the inside of the drainage groove 41, a power conversion wheel 45 rotatably connected to the center of the positioning block 44, and a triangular scraping rod 46 fixedly connected to one end of the power conversion wheel 45 close to the positioning block 44.

[0046] The driving rod 23 is rotatably connected to the inside of the positioning frame 21, and the adapter disc 27 is slidingly connected to the top of the driving rod 23, so that the adapter disc 27 can slide along the outer wall of the limiting strip 26 and the driving rod 23.

[0047] The bottom sphere of the spherical limiting rod 29 is provided as a hollow core, so that when the sphere of the spherical limiting rod 29 hits the liquid surface, the sedimentation efficiency can be improved, one end of the adapter rod 210 away from the spherical limiting rod 29 is arranged in the inside of the dial disc 25, so that in the process of driving the dial disc 25 to rotate by the driving rod 23, the adapter rod 210 will be continuously dialled.

[0048] The double-layer chuck 34 is arranged in the inside of the adapter disc 27, so that when the double-layer chuck 34 moves, the adapter disc 27 will be dialled to slide along the driving rod 23.

[0049] Three strip-shaped scraping blades are annularly distributed at one end of the triangular scraping rod 46 away from the power conversion wheel 45, and the three strip-shaped scraping blades of the triangular scraping rod 46 are all arranged in an inclined manner, so that the scraping effect of the triangular scraping rod 46 on the filter screen disc 43 is better.

[0050] Working principle: in the initial state, the connecting rod 28, the dial disc 25 and the adapter disc 27 are all in a vertical state, and the dial disc 25 is in a vertical state with the driving rod 23.

[0051] When working, the worker first needs to discharge the printing and dyeing wastewater into the inside of the sedimentation tank 11, and then rotates the rotating handle 33, which drives the threaded rod 32 to rotate along the inside of the distance increasing block 31. At this time, the threaded rod 32 drives the double-layer chuck 34 to descend. Since the double-layer chuck 34 is arranged in the inside of the adapter disc 27, and the adapter disc 27 is slidingly connected to the top of the driving rod 23, the double-layer chuck 34 drives the adapter disc 27 to slide along the limiting strip 26 and the outer wall of the driving rod 23;

[0052] The adapter disc 27 rotates the push disc 25 through the connecting rod 28, and the rotating push disc 25 gradually rotates around the driving rod 23 and the rotating groove 24, so that the push disc 25 is inclined. Conversely, the worker reversely rotates the rotating handle 33, which drives the adapter disc 27 to ascend through the threaded rod 32 and the double-layer chuck 34, so as to adjust the inclination angle of the push disc 25 through the connecting rod 28;

[0053] When the printing and dyeing wastewater is discharged into the inside of the sedimentation tank 11, the worker starts the driving device 22, which drives the driving rod 23 fixedly connected to the output shaft to rotate. At this time, the driving rod 23 drives the inclined push disc 25 and the adapter disc 27 to rotate. During the rotation of the inclined push disc 25, the spherical limiting rod 29 is slidingly connected to the side of the positioning frame 21 away from the sedimentation tank 11. At this time, the push disc 25 drives the spherical limiting rod 29 to move vertically and reciprocally through the adapter rod 210;

[0054] Since the bottom ball of the spherical limiting rod 29 is arranged as a hollow core, when the ball of the spherical limiting rod 29 hits the printing and dyeing wastewater surface of the sedimentation tank 11, the spherical limiting rod 29 will continuously beat the precipitated printing and dyeing wastewater. The device can generate regular physical disturbance in the wastewater through continuous beating action, and when the ball of the spherical limiting rod 29 contacts the wastewater, it will cause local water flow fluctuation and pressure change, just like making oil droplets gather and float in sesame oil. In the printing and dyeing wastewater, the device can make the pollutant particles better gather and precipitate. Through continuous physical disturbance, the device can make the pollutants in the printing and dyeing wastewater complete precipitation in a short time. Compared with the traditional sedimentation tank 11, the device shortens the time of wastewater staying in the sedimentation tank 11, thereby improving the processing capacity of the entire printing and dyeing wastewater treatment system.

[0055] And the greater the inclination angle of the adapter disc 27 adjusting the dial disc 25 through the connecting rod 28, the greater the vertical reciprocating movement of the dial disc 25 dialing the adapter rod 210, so as to actively control the frequency and force of the beating of the spherical limiting rod 29, better cope with the changes of the quality and flow of the printing and dyeing wastewater, regardless of the concentration and particle size of the pollutants in the wastewater, and by adjusting the parameters of the beating action, the stability of the effluent quality is ensured, and it can work with other processes in the sedimentation tank 11 (such as adding flocculants and other chemical precipitation methods). After adding the flocculants, the beating of the spherical limiting rod 29 can better mix the flocculants with the pollutants, improve the flocculation effect, and further enhance the sedimentation effect.

[0056] After the printing and dyeing wastewater is precipitated in the sedimentation tank 11, the staff needs to pull out the sealing plug 42 away from the sedimentation tank 11, and then the water source after precipitation will flow out of the inside of the sedimentation tank 11 through the drain groove 41. In this process, the water flowing out along the drain groove 41 will drive the power conversion wheel 45 to rotate around the positioning block 44, and at the same time the power conversion wheel 45 will drive the triangular scraper rod 46 to scrape the surface of the filter screen disc 43;

[0057] Because the end of the triangular scraper rod 46 away from the power conversion wheel 45 is annularly distributed with three strip-shaped scraping pieces, and the three strip-shaped scraping pieces of the triangular scraper rod 46 are all arranged in an inclined manner, the scraping effect of the triangular scraper rod 46 on the filter screen disc 43 is better, so that the water can be converted into the mechanical energy of the power conversion wheel 45, avoiding the filter screen disc 43 being blocked by the precipitated floating objects during the drainage process, reducing the need for additional power input, and at the same time, the triangular scraper rod 46 is driven by the water flow to clean the filter screen disc 43, without the need for a separate motor or other power equipment for the scraper rod cleaning, thereby reducing the operating cost of the entire sewage treatment system;

[0058] Secondly, the automatic cleaning mechanism of the triangular scraper rod 46 and the power conversion wheel 45 driven by the water flow is used to realize real-time cleaning during the drainage process. As long as there is water flow through the drain groove 41, the scraper rod of the triangular scraper rod 46 will continuously clean the filter screen disc 43, ensuring the good working state of the filter screen disc 43. This automatic operation mode reduces the need for manual intervention, improves the automation level and operation stability of the entire sewage treatment system.
