Description

Technical Field

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

[0002] When printing and dyeing wastewater is subjected to multi-stage separation, the sedimentation tank is usually used as a preliminary treatment step because of its relatively simple structure and low operating cost. It can remove a considerable portion of pollutants in the wastewater at a lower cost. This treatment method of easy first and difficult later, coarse first and fine later conforms to the principle of economy and efficiency. For example, compared with some advanced oxidation treatment technologies or deep filtration technologies, the construction and operation costs of the sedimentation tank are lower, but it can achieve effective separation of a large number of suspended impurities.

[0003] In the process of separating printing and dyeing wastewater, traditional sedimentation tanks mainly rely on gravity sedimentation to allow suspended particles to settle naturally. For some tiny particles, colloids or emulsified pollutants, the sedimentation effect is poor. These substances will be suspended in the water for a long time and are difficult to settle to the bottom, resulting in a long sedimentation time to achieve a certain treatment effect. Moreover, in the actual production process, the flow rate and water quality changes of printing and dyeing wastewater will affect the sedimentation effect, making the effluent water quality unstable. In addition, traditional sedimentation tanks generally wait passively for pollutants to settle, and there is no active physical method to promote the sedimentation process. If the pollutant particles in the wastewater are small or have the same charge, there is repulsion between them, and it is difficult to naturally aggregate and precipitate. In this case, traditional sedimentation tanks cannot effectively accelerate the sedimentation process;

[0004] In the printing and dyeing production process, in order to improve the precipitation effect, traditional methods often require the addition of a large amount of chemical agents or the extension of the precipitation time. The addition of chemical agents not only increases the treatment cost, but also introduces new pollutants. In actual production, excessively long precipitation time cannot meet the production progress requirements, resulting in the wastewater not being treated in time to meet the discharge standards.

[0005] In traditional sedimentation tanks, if there are no effective anti-clogging measures, as the drainage process continues, the floating objects after precipitation are easy to accumulate at the filter disc. These floating objects will gradually block the pores of the filter disc, causing the drainage speed to slow down. When the filter disc is seriously blocked, it needs to be cleaned manually, which is not only time-consuming and laborious, but also during the cleaning period, the sedimentation tank cannot be drained normally, affecting the continuity of the entire wastewater treatment process. In addition, the cleaning of the filter disc in traditional sedimentation tanks is usually regular manual inspection and cleaning. This method is difficult to deal with the blockage problem of the filter disc in real time. Due to the long time interval between manual cleaning, the blockage of the filter disc has had a negative impact on the drainage and treatment process between two cleanings.

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

[0007] In view of the shortcomings of the prior art, the object of the present invention is to provide a printing and dyeing wastewater treatment device with a multi-stage separation function.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a printing and dyeing wastewater treatment device with multi-stage separation function, comprising a sedimentation tank, wherein the top of the sedimentation tank is provided with an auxiliary separation component for assisting the sedimentation of the printing and dyeing wastewater, an amplitude adjustment component for adjusting the sliding amplitude of the auxiliary separation component is provided above the sedimentation tank, and an anti-blocking component for ensuring smooth drainage is provided inside the sedimentation tank.

[0009] Preferably, the auxiliary separation component includes a positioning frame, the positioning frame is fixedly connected to the top of the sedimentation tank, the top of the positioning frame is fixedly connected to a driving device, the output shaft end of the driving device is fixedly connected to a driving rod, the bottom of the driving rod is provided with a rotating groove, and the outer side of the rotating groove is rotatably connected to a toggle disk.

[0010] Preferably, the auxiliary separation component also includes a limit bar, which is fixedly connected to the top of the driving rod, and the outer wall of the limit bar is slidably connected to a connecting plate, the bottom of the connecting plate is rotatably connected to a connecting rod, and the end of the connecting rod away from the connecting plate is rotatably connected to the top of the toggle plate, the end of the positioning frame away from the sedimentation tank is slidably connected to a spherical limit rod, and the outer wall of the spherical limit rod is fixedly connected to the connecting rod.

[0011] Preferably, the amplitude adjustment assembly includes a distance increasing block, which is fixedly connected to the top of the positioning frame, the internal thread of the distance increasing block is rotatably connected to a threaded rod, the top of the threaded rod is fixedly connected to a rotating handle, and the bottom of the threaded rod is fixedly connected to a double-layer chuck.

[0012] Preferably, the anti-clogging component includes a drainage groove, which is opened inside the sedimentation tank. A sealing plug is provided on the side of the drainage groove away from the sedimentation tank, and a filter disc is clamped inside the drainage groove.

[0013] Preferably, the anti-blocking component also includes a positioning block, the positioning block is fixedly connected to the inside of the drainage trough, the center of the positioning block is rotatably connected to a power conversion wheel, and one end of the power conversion wheel close to the positioning block is fixedly connected to a triangular scraper rod.

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

[0015] Preferably, the bottom sphere of the spherical limiting rod is configured as a hollow core, and one end of the connecting rod away from the spherical limiting rod is configured inside the dial.

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

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

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

[0019] 1. Through the setting of the auxiliary separation component and the amplitude adjustment component, the driving rod can be driven to rotate during the rotation of the driving rod, and the driving plate can drive the connecting rod to move vertically back and forth, and finally drive the spherical limit rod to continuously beat the precipitated printing and dyeing wastewater. The continuous beating action will produce regular physical disturbances in the wastewater. Different from the passive precipitation method of the traditional sedimentation tank, it can actively break the stable state of pollutants in the wastewater. For example, for tiny particles or colloids, the beating action can overcome the charge repulsion between particles or the stability of colloids, prompting them to collide and aggregate with each other to form larger particles, thereby accelerating the precipitation speed;

[0020] Secondly, when the ball of the spherical limit rod contacts the wastewater, it will cause local water flow fluctuations and pressure changes, just like causing oil droplets to gather and float in sesame oil. In the printing and dyeing wastewater, the pollutant particles can be better gathered and precipitated. Through continuous physical disturbance, the device can make the pollutants in the printing and dyeing wastewater complete precipitation in a shorter time. Compared with traditional sedimentation tanks, this greatly improves the sedimentation efficiency and shortens the time that wastewater stays in the sedimentation tank, thereby improving the treatment capacity of the entire printing and dyeing wastewater treatment system.

[0021] Finally, the threaded rod can be rotated to adjust the position of the connecting plate through the double-layer chuck, and the connecting plate can adjust the offset amplitude of the toggle plate through the connecting rod, so as to actively control the beating frequency and strength of the spherical limit rod, and better cope with the changes in the water quality and flow of printing and dyeing wastewater. No matter how the concentration and particle size of pollutants in the wastewater change, by adjusting the parameters of the beating action, it can effectively promote sedimentation and ensure the stability of the effluent water quality, which is difficult to do in traditional sedimentation tanks, because the sedimentation effect of traditional sedimentation tanks is greatly affected by the properties of the wastewater itself, and this device with an active sedimentation promotion mechanism can work in conjunction with other processes in the sedimentation tank (such as chemical precipitation methods such as adding flocculants). After adding flocculants, the beating of the spherical limit rod can better mix the flocculants with pollutants, improve the flocculation effect, and further enhance the sedimentation effect. This is more efficient than the traditional sedimentation tank using chemical precipitation methods alone, reflecting the good adaptability and synergistic advantages of the device structure.

[0022] 2. Through the setting of anti-clogging components, in the process of collecting the effluent water quality, the precipitated water source will flow out through the drainage trough. At this time, the flowing water source will drive the power conversion wheel to rotate, so that the water energy is converted into the mechanical energy of the power conversion wheel. Finally, the power conversion wheel drives the triangular scraper to clean the surface of the filter disc, so as to avoid the filter disc being blocked by the precipitated floating objects during the drainage process, and reduce the demand for additional power input. For example, in the long-term operation process, the triangular scraper is driven by the energy of the water flow to clean the filter disc, and there is no need to equip the scraper with a motor and other power equipment separately for cleaning, thereby reducing the operation cost of the entire sewage treatment system;

[0023] Secondly, the automatic cleaning mechanism of the power conversion wheel and the triangular scraper rod driven by water flow realizes real-time cleaning during the drainage process. As long as there is water flowing through the drainage trough, the scraper rod will continue to clean the filter disc, ensuring the good working condition of the filter disc. This automated operation mode reduces the need for human intervention, improves the degree of automation and operational stability of the entire sewage treatment system, and enables the sedimentation tank to operate more continuously and stably.

[0039] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0040] Implementation example Figures 1 to 9 As shown, a printing and dyeing wastewater treatment device with a multi-stage separation function is provided as an embodiment of the present invention, including a sedimentation tank 11, the top of the sedimentation tank 11 is provided with an auxiliary separation component for assisting the sedimentation of the printing and dyeing wastewater, the upper part of the sedimentation tank 11 is provided with an amplitude adjustment component for adjusting the sliding amplitude of the auxiliary separation component, and the interior of the sedimentation tank 11 is provided with an anti-blocking component for ensuring smooth drainage.

[0041] The auxiliary separation component includes a positioning frame 21, which is fixedly connected to the top of the sedimentation tank 11. The top of the positioning frame 21 is fixedly connected to a driving device 22. The output shaft end of the driving device 22 is fixedly connected to a driving rod 23. A rotating groove 24 is provided at the bottom of the driving rod 23, and a toggle disk 25 is rotatably connected to the outer side of the rotating groove 24.

[0042] The auxiliary separation component also includes a limit bar 26, which is fixedly connected to the top of the driving rod 23. The outer wall of the limit bar 26 is slidably connected to a connecting plate 27. The bottom of the connecting plate 27 is rotatably connected to a connecting rod 28, and the end of the connecting rod 28 away from the connecting plate 27 is rotatably connected to the top of the toggle plate 25. The end of the positioning frame 21 away from the sedimentation tank 11 is slidably connected to a spherical limit rod 29, and the outer wall of the spherical limit rod 29 is fixedly connected to a connecting rod 210.

[0043] The amplitude adjustment assembly includes a distance increasing block 31, which is fixedly connected to the top of the positioning frame 21. The internal thread of the distance increasing block 31 is rotatably connected to a threaded rod 32, the top of the threaded rod 32 is fixedly connected to a rotating handle 33, and the bottom of the threaded rod 32 is fixedly connected to a double-layer chuck 34.

[0044] The anti-clogging component includes a drainage groove 41 , which is opened inside the sedimentation tank 11 . A sealing plug 42 is provided on the side of the drainage groove 41 away from the sedimentation tank 11 , and a filter plate 43 is clamped inside the drainage groove 41 .

[0045] The anti-clogging component also includes a positioning block 44, which is fixedly connected to the inside of the drainage groove 41. The center of the positioning block 44 is rotatably connected to a power conversion wheel 45, and one end of the power conversion wheel 45 close to the positioning block 44 is fixedly connected to a triangular scraper rod 46.

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

[0047] The bottom sphere of the spherical limit rod 29 is set to be hollow, so that when the sphere of the spherical limit rod 29 hits the liquid surface, the sedimentation efficiency can be improved to a certain extent. The end of the connecting rod 210 away from the spherical limit rod 29 is set inside the toggle disk 25, so that the driving rod 23 will continuously toggle the connecting rod 210 during the process of driving the toggle disk 25 to rotate.

[0048] The double-layer chuck 34 is disposed inside the connecting plate 27 , so that when the double-layer chuck 34 moves, it will push the connecting plate 27 to slide along the driving rod 23 .

[0049] One end of the triangular scraper rod 46 away from the power conversion wheel 45 is provided with three strip scrapers in a ring shape, and the three strip scrapers of the triangular scraper rod 46 are all arranged to be inclined, so that the triangular scraper rod 46 has a better scraping effect on the filter plate 43.

[0050] Working principle: In the initial state, the connecting rod 28, the toggle plate 25 and the connecting plate 27 are all in a vertical state, and the toggle plate 25 and the driving rod 23 are in a vertical state.

[0051] During operation, the staff first needs to discharge the printing and dyeing wastewater into the sedimentation tank 11, and then turn the rotating handle 33, which will drive 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 inside the connecting plate 27, and the connecting plate 27 is slidably connected to the top of the driving rod 23, the double-layer chuck 34 drives the connecting plate 27 to slide along the outer wall of the limiting strip 26 and the driving rod 23.

[0052] The connecting plate 27 is rotated by contacting the toggle plate 25 through the connecting rod 28, and the rotating toggle plate 25 gradually rotates around the driving rod 23 and the rotating groove 24, so that the toggle plate 25 is tilted. Conversely, the staff rotates the rotating handle 33 in the opposite direction, and the rotating handle 33 pulls the connecting plate 27 up through the threaded rod 32 and the double-layer chuck 34, so that the connecting plate 27 adjusts the tilt angle of the toggle plate 25 through the connecting rod 28;

[0053] When the printing and dyeing wastewater is discharged into the sedimentation tank 11, the staff starts the driving device 22, and then the driving device 22 drives the driving rod 23 fixedly connected to the output shaft thereof to rotate, and at this time the driving rod 23 drives the inclined toggle plate 25 and the connecting plate 27 to rotate, and during the rotation of the inclined toggle plate 25, because the spherical limiting rod 29 is slidably connected to the side of the positioning frame 21 away from the sedimentation tank 11, at this time the toggle plate 25 will toggle the spherical limiting rod 29 through the connecting rod 210 to move vertically back and forth;

[0054] Because the bottom sphere of the spherical limit rod 29 is set to be hollow, when the ball of the spherical limit rod 29 hits the surface of the printing and dyeing wastewater in the sedimentation tank 11, the spherical limit rod 29 will continue to beat the precipitated printing and dyeing wastewater, and can achieve continuous beating action to produce regular physical disturbances in the wastewater, and when the ball of the spherical limit rod 29 contacts the wastewater, it will cause local water flow fluctuations and pressure changes, just like making oil droplets gather and float in sesame oil, which can make the pollutant particles in the printing and dyeing wastewater better gather and precipitate. Through continuous physical disturbance, the device can make the pollutants in the printing and dyeing wastewater complete precipitation in a shorter time. Compared with the traditional sedimentation tank 11, this shortens the time that the wastewater stays in the sedimentation tank 11, thereby improving the treatment capacity of the entire printing and dyeing wastewater treatment system.

[0055] The greater the inclination angle of the toggle plate 25 adjusted by the connecting plate 27 through the connecting rod 28, the greater the amplitude of the vertical reciprocating movement of the connecting rod 210 driven by the toggle plate 25, so that the beating frequency and strength of the spherical limit rod 29 can be actively controlled, and the changes in the water quality and flow rate of printing and dyeing wastewater can be better responded to. No matter how the concentration and particle size of pollutants in the wastewater change, the stability of the effluent water quality can be guaranteed by adjusting the parameters of the beating action, and at the same time, it can work in coordination with other processes in the sedimentation tank 11 (such as chemical precipitation methods such as adding flocculants). After adding the flocculant, the beating of the spherical limit rod 29 can better mix the flocculant with the pollutants, improve the flocculation effect, and further enhance the sedimentation effect.

[0056] After the sedimentation tank 11 has completed the sedimentation of the printing and dyeing wastewater, the staff needs to pull out the sealing plug 42 in a direction away from the sedimentation tank 11, and then the precipitated water will flow out of the sedimentation tank 11 through the drainage groove 41. During this process, the water flowing out of the drainage 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 46 to scrape the surface of the filter plate 43;

[0057] Because the end of the triangular scraper rod 46 away from the power conversion wheel 45 is provided with three strip scrapers in a ring shape, and the three strip scrapers of the triangular scraper rod 46 are all arranged in an inclined shape, the triangular scraper rod 46 has a better scraping effect on the filter plate 43, so that the water energy is converted into the mechanical energy of the power conversion wheel 45, and the filter plate 43 is prevented from being blocked by the precipitated floating objects during the drainage process, and the additional power input demand is reduced. At the same time, the triangular scraper rod 46 is driven by the energy of the water flow itself to clean the filter plate 43, and there is no need to equip the scraper rod with a motor or other power equipment separately for cleaning, thereby reducing the operation cost of the entire sewage treatment system;

[0058] Secondly, the automatic cleaning mechanism of the power conversion wheel 45 and the triangular scraper 46 is driven by water flow, thereby realizing real-time cleaning during the drainage process. As long as water flows through the drainage trough 41, the scraper of the triangular scraper 46 will continue to clean the filter plate 43, thereby ensuring the good working condition of the filter plate 43. This automated operation mode reduces the need for manual intervention and improves the automation level and operational stability of the entire sewage treatment system.
