Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and in particular relates to a wastewater treatment device for washing Codonopsis pilosula mud. Background Technology

[0002] Codonopsis pilosula is a commonly used traditional Chinese medicine for tonifying the body, possessing the core medicinal effects of invigorating the spleen and lungs, and replenishing qi. Its harvesting cycle is concentrated in autumn after the above-ground parts of the plant wither, continuing until the following spring before the plant sprouts. Codonopsis pilosula harvested in autumn has a higher concentration of starchy substances in its roots, resulting in a higher dry weight and better quality. However, as the soil temperature rises in spring, Codonopsis pilosula enters the sprouting stage, consuming a large amount of nutrients stored in the roots, ultimately leading to a decline in both the quality and yield of the medicinal material. According to relevant meteorological data, in Chongqing and other concentrated areas for Codonopsis pilosula cultivation and processing, the local noon solar altitude angle ranges from 37° to 75° during the autumn to spring harvesting period, with the peak solar altitude angle occurring at noon. The natural drying conditions during this period can meet some of the needs of initial processing, but the subsequent cleaning process remains a core and necessary step in the initial processing of Codonopsis pilosula.

[0003] After the harvesting of Codonopsis pilosula and the initial removal of surface soil, the processing stage requires a thorough cleaning of the fine soil remaining on its surface. This process generates a large amount of wastewater with a high mud content. If this wastewater is discharged directly without effective treatment, it will not only cause mud and sand pollution to the surrounding environment but also result in a significant waste of water resources, which is completely inconsistent with the water-saving and circular production requirements of the Chinese medicinal herb processing industry. Therefore, it is essential to equip the process with corresponding dedicated wastewater treatment equipment to purify the cleaning wastewater for reuse, thereby reducing water consumption in the processing stage.

[0004] Most existing wastewater treatment devices for Codonopsis pilosula cleaning on the market only use a single static filtration mode to treat the wastewater. This traditional treatment method is a passive filtration operation with very low overall wastewater treatment efficiency. At the same time, the large amount of large-particle soil impurities carried in the wastewater cannot be quickly flocculated and settled in the pretreatment stage, and can easily enter the subsequent filtration and purification processes directly, frequently causing filter media blockage, equipment overload failures, and significantly increasing equipment maintenance costs and downtime probability. It is difficult to adapt to the high-load continuous production demand during the peak harvesting and processing period of Codonopsis pilosula. The industry urgently needs a targeted and efficient wastewater treatment device for Codonopsis pilosula soil cleaning to solve the above pain points. Therefore, we have proposed a wastewater treatment device for Codonopsis pilosula soil cleaning. Summary of the Invention

The preliminarily clarified wastewater can then enter the next process through the water inlet pipe, thus reducing the clogging of subsequent processes by large particulate impurities. 2. The wastewater flowing down is dispersed by the material dispersion component through rotation and shaking. The wastewater is dispersed and thrown into the preliminary centrifugation component, which then performs rotation and centrifugation to initially separate the wastewater and impurities. 3. The wastewater that has undergone initial centrifugation enters the secondary centrifugation unit, while the aeration unit drives the secondary centrifugation unit to work simultaneously. The secondary centrifugation unit further centrifuges and separates the wastewater, thereby fully treating the wastewater and meeting the requirements for efficient wastewater treatment. In summary, this solution has a simple structure and a novel design. By aerating and stirring the wastewater, the flocculant can fully exert its function and complete the sedimentation of large particulate impurities. The wastewater is then shaken and rotated to disperse it, causing it to be thrown onto the inner wall of the initial centrifugal component for rapid contact and centrifugation. A second centrifugation is then performed to achieve efficient wastewater treatment. Attached Figure Description

[0034] like Figures 1-10 As shown, an embodiment of the present invention proposes a wastewater treatment device for washing Codonopsis pilosula soil, including a flocculation sedimentation tank 1, multiple support plates 2, a water receiving tank 3, and a water receiving pipe 4. The flocculation sedimentation tank 1 and the water receiving tank 3 are fixed together by the support plates 2 and connected by the water receiving pipe 4. A driving aeration component 5 is provided on one side of the water receiving tank 3. The driving aeration component 5 aerates the water in the flocculation sedimentation tank 1. A secondary centrifugal component 6 located inside the water receiving tank 3 is connected to the driving aeration component 5. The secondary centrifugal component 6 is provided with a preliminary centrifugal component 7, which is used to perform preliminary centrifugation on the water flowing down from the water receiving pipe 4. The centrifuged water is then subjected to final centrifugation by the secondary centrifugal component 6. The preliminary centrifugal component 7 is provided with a material dispersion component 8, which is used to shake and rotate the water flowing down from the water receiving pipe 4 to disperse it.

[0035] like Figure 6As shown, the aeration drive assembly 5 includes a fixed plate 501 fixedly connected to one side of the water receiving tank 3. An air inlet hood 502 is fixedly connected to the bottom of the fixed plate 501. Two mounting plates 503 are fixedly connected inside the air inlet hood 502. A first drive motor 504 is fixedly connected between the two mounting plates 503. A fan blade 505 is fixedly connected to the output shaft of the first drive motor 504. A transmission shaft 506 is fixedly connected to the top of the output shaft of the first drive motor 504. A first driving bevel gear 507 is fixedly connected to the top of the transmission shaft 506. A rotating tube 508 is movably sleeved on the flocculation sedimentation tank 1 above the first driving bevel gear 507. A first driven bevel gear 509 is fixedly sleeved on the outside of the rotating tube 508, and the first driving bevel gear 507 meshes with the first driven bevel gear 509 for transmission. An air inlet is rotatably connected to the left end of the rotating tube 508. The bottom end of the air inlet pipe 510 is fixedly connected to and communicates with the air inlet hood 502. The right end of the rotating pipe 508 is fixedly connected to and communicates with the aeration pipe 511. The outer ring of the aeration pipe 511 is provided with multiple aeration holes 512, and the outer array of the aeration pipe 511 is provided with multiple stirring rods 513. The first drive motor 504 drives the fan blade 505 and the drive shaft 506 to rotate. The fan blade 505 blows air upward, so that the gas enters the air inlet pipe 510 and finally enters the aeration pipe 511 through the rotating pipe 508. The drive shaft 506 drives the rotating pipe 508 to rotate through the first active bevel gear 507 and the first driven bevel gear 509, which in turn drives the aeration pipe 511 to rotate. In this way, the aeration pipe 511 not only rotates and aerates, but also drives the stirring rods 513 to stir, which is conducive to the flocculant to play its role and helps the sedimentation of large particulate impurities.

[0036] like Figure 6 and Figure 7 As shown, the secondary centrifuge assembly 6 includes a chassis 601 fixedly connected to the inner wall of the bottom of the water receiving tank 3. Two first slide rails 602 are fixedly connected to the top of the chassis 601. A first fixing ring 603 is slidably provided between the two first slide rails 602. A secondary centrifuge cylinder 604 is fixedly sleeved inside the first fixing ring 603. A first pulley 605 is fixedly sleeved on the top of the secondary centrifuge cylinder 604. A second pulley 606 is fixedly sleeved on one side of the first pulley 605 outside the drive shaft 506. A belt 607 is sleeved on the outside of the first pulley 605 and the second pulley 606. The drive shaft 506 drives the first pulley 605 to rotate through the second pulley 606 and the belt 607. The first pulley 605 drives the secondary centrifuge cylinder 604 to rotate. The secondary centrifuge cylinder 604 drives the first fixing ring 603 to rotate on the first slide rail 602 for centrifugal centrifugation.

[0037] like Figure 7 and Figure 8As shown, the preliminary centrifuge assembly 7 includes a preliminary centrifuge cylinder 701. A second fixing ring 702 is fixedly connected to the bottom of the preliminary centrifuge cylinder 701. Two second slide rails 703 are provided on the outside of the second fixing ring 702, and the second fixing ring 702 and the second slide rails 703 are slidably arranged. Two support rods 704 are fixedly connected to the bottom of the second slide rails 703, and the bottom ends of the support rods 704 are fixedly connected to the chassis 601. A sleeve 705 is fixedly connected to the bottom of the preliminary centrifuge cylinder 701. A second driven bevel gear 706 is fixedly sleeved on the outside of the sleeve 705. One side is provided with a side plate 707 fixedly connected to the support rod 704. A second drive motor 708 is fixedly connected to the side plate 707. The output shaft of the second drive motor 708 is fixedly connected to a second active bevel gear 709. The second active bevel gear 709 meshes with the second driven bevel gear 706 for transmission. The second drive motor 708 drives the sleeve 705 to rotate through the second active bevel gear 709 and the second driven bevel gear 706. The sleeve 705 drives the preliminary centrifuge cylinder 701 to rotate. The preliminary centrifuge cylinder 701 drives the second fixed ring 702 to rotate on the second slide rail 703 for centrifugal centrifugation.

[0038] like Figure 8 and Figure 9 As shown, the material dispersion assembly 8 includes a lifting shaft 801 that moves through the bottom wall of the primary centrifuge cylinder 701. A dispersion cover 802 is fixedly connected to the top of the lifting shaft 801. Multiple guide bars 803 are arranged in an array on the outside of the lifting shaft 801. A toggle rod 804 is fixedly connected to the bottom of the lifting shaft 801. A corrugated ring 805 is provided at the bottom of the toggle rod 804. Two positioning rods 806 are fixedly connected to the bottom of the corrugated ring 805, and the bottom of the positioning rods 806 is fixedly connected to the chassis 601. When the primary centrifuge cylinder 701 rotates, it also drives the lifting shaft 801 to rotate with the help of the guide bars 803. The lifting shaft 801 drives the dispersion cover 802 and the toggle rod 804 to rotate. The toggle rod 804 rotates on the corrugated ring 805 and will intermittently rise and fall, thereby driving the lifting shaft 801 and the dispersion cover 802 to rise and fall. In this way, the dispersion cover 802 will shake and rotate up and down, which facilitates the wastewater to be thrown onto the inner wall of the primary centrifuge cylinder 701 for rapid centrifugation.

[0039] like Figure 10 As shown, the flocculation sedimentation tank 1 has three partitions 9 inside. The middle partition 9 is fixedly connected to the bottom inner wall of the flocculation sedimentation tank 1, and the two partitions 9 on both sides are fixedly connected to the top of the flocculation sedimentation tank 1. The aeration pipe 511 is movably sleeved in the partition 9. The three partitions 9 divide the flocculation sedimentation tank 1 into 4 spaces. The wastewater settles to the maximum extent in the first space on the left until the first space on the right, where large particulate impurities in the wastewater have been reduced to the maximum extent.

[0040] like Figure 10As shown, an inlet pipe 10 is fixedly connected to the left side of the flocculation sedimentation tank 1, and an outlet pipe 11 is fixedly connected to the side of the water tank 3. Wastewater enters the flocculation sedimentation tank 1 through the inlet pipe 10 for flocculation and sedimentation, and the treated water is discharged through the outlet pipe 11 for reuse.

[0041] like Figure 8 and Figure 9 As shown, the bottom wall of the initial centrifuge cylinder 701 has a lifting hole, and the inner wall of the lifting hole has an array of guide grooves. The guide bar 803 is movably sleeved in the guide groove. The guide groove guides the guide bar 803 and also facilitates the rotation of the lifting shaft 801.

[0042] like Figure 3 and Figure 7 As shown, the bottom of the secondary centrifuge tube 604 is open, and the chassis 601 is fixedly connected to the water receiving tank 3 by multiple bolts.

[0043] like Figure 6 As shown, the top of the air intake shroud 502 has a through hole, and a sealed bearing is fitted inside the through hole. The drive shaft 506 is fitted inside the sealed bearing, and the sealed bearing ensures that gas enters the air intake pipe 510.

[0044] Working principle: Flocculation and sedimentation pretreatment stage The wastewater from washing Codonopsis pilosula soil is first injected into the flocculation sedimentation tank 1 through the inlet pipe 10, and a flocculant suitable for the muddy wastewater is added to the tank in advance. After the first drive motor 504 is started, its output shaft will synchronously drive the components to rotate: directly drive the fan blade 505 to rotate at high speed, and the airflow generated by the fan blade 505 flows through the air inlet cover 502 into the air inlet pipe 510, and finally into the interior of the connected rotating pipe 508, and is continuously sprayed out from the multiple aeration holes 512 arrayed on the surface of the connected aeration pipe 511; it also drives the first active bevel gear 507 at the end to mesh with the first driven bevel gear 509 through the transmission shaft 506 connected to the top of the output shaft, thereby driving the entire set of rotating pipe 508 and aeration pipe 511 components to rotate at a uniform speed. The rotating aeration pipe 511 continuously outputs aeration air through the aeration holes 512 distributed throughout the pipe wall, keeping the wastewater in the tank in a slightly agitated state, allowing the flocculant to fully contact and react with the silt and impurities in the wastewater. On the other hand, it simultaneously drives the multiple stirring rods 513 arranged in an array on the outside of the pipe wall to perform circular motion, further enhancing the disturbance effect of the water body, preventing large particles of silt from settling and clumping at the bottom in advance, allowing the flocculation reaction to be more complete, and quickly causing the silt and impurities to clump together to form large-volume flocs.

[0045] Meanwhile, the three staggered partitions 9 inside the flocculation sedimentation tank 1 divide the internal space of the tank into four interconnected baffle channels. As the wastewater flows along the channels, the flocs collide and aggregate continuously. Finally, the large particles of silt flocs settle fully in the bottom area of ​​the tank. The pretreated supernatant wastewater is guided from the water inlet pipe into the centrifugation process inside the water inlet tank below. This intercepts most of the large particles of impurities at the source, preventing blockages in subsequent processes.

[0046] Wastewater dispersion and preliminary centrifugation stage The pretreated wastewater, guided by the water inlet pipe 4, falls directly into the material dispersion component 8 inside the primary centrifugal assembly 7. After the second drive motor 708 configured in the device starts, it meshes with the second driven bevel gear 706 through the second active bevel gear 709 at the end of the output shaft, driving the sleeve 705 and the primary centrifugal cylinder 701 fixed at the top to rotate at a uniform speed. The second fixing ring 702 at the bottom of the primary centrifugal cylinder 701 rotates smoothly along the matching second slide rail 703, ensuring the coaxiality of the cylinder body.

[0047] During the rotation of the initial centrifuge cylinder 701, the guide groove inside the lifting hole at the bottom of the cylinder engages with the guide strip 803 on the outside of the lifting shaft 801, causing the lifting shaft 801, the top dispersion cover 802, and the bottom actuating rod 804 to rotate together. As the actuating rod 804 rolls around the top surface of the fixed corrugated ring 805, it follows the undulating trajectory of the corrugated ring 805, causing the actuating rod 804, the lifting shaft 801, and the dispersion cover 802 to perform high-frequency up-and-down reciprocating motion. This results in the dispersion cover 802 simultaneously completing a combined action of rotation and high-frequency shaking, evenly dispersing the falling wastewater in all directions. This allows the wastewater to contact the inner wall of the initial centrifuge cylinder 701 more quickly. Under the high-speed centrifugal action of the initial centrifuge cylinder 701, the first stage of solid-liquid separation is completed. Most of the remaining fine mud and sand impurities are trapped inside the initial centrifuge cylinder, and the pre-purified wastewater overflows into the outer secondary centrifuge assembly 6.

[0048] Secondary deep centrifugation stage During the rotation of the transmission shaft 506 driven by the first drive motor 504, the second pulley 606 fixed on the shaft drives the first pulley 605 to rotate synchronously via the transmission belt 607, thereby driving the entire secondary centrifuge 604 to rotate at high speed. The first fixed ring 603 at the bottom of the secondary centrifuge 604 slides and rotates smoothly along the first slide rail 602. The pre-purified wastewater flowing into the secondary centrifuge 604 undergoes deeper solid-liquid separation under the high-speed centrifugal action of the secondary centrifuge 604, completely intercepting the fine suspended impurities that were not completely separated in the preliminary centrifugation process. The purified water, after completing the entire purification process, is finally collected in the water receiving tank 3 and then discharged through the water outlet pipe 11 connected to the side wall, which can be directly reused in the Codonopsis pilosula cleaning process, realizing the recycling of water resources.
