[0002] Wastewater from the production of organic fertilizer from Chinese medicinal herb residue is characterized by high suspended solids, high organic matter, and large fluctuations in water quality. Direct entry into the biological treatment system can easily lead to sludge bulking and low treatment efficiency. Multi-stage sedimentation tanks remove suspended solids in stages, creating stable conditions for subsequent biological treatment.

[0003] The common treatment method is to use appropriate agents to precipitate impurities in the wastewater and then settle them in a sedimentation tank. However, due to limited space, existing sedimentation tanks cannot be made too large, and the continuously generated wastewater can easily be discharged directly without sufficient sedimentation.

[0004] Therefore, it is necessary to provide a new multi-stage sedimentation tank for wastewater from the production of organic fertilizer from Chinese medicinal herb residues to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem of limited sedimentation tank volume preventing sufficient sedimentation of wastewater before discharge, this utility model provides a multi-stage sedimentation tank for wastewater from the production of organic fertilizer from Chinese medicinal herb residues.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-3 ,in, Figure 1 A schematic diagram of the main cross-sectional structure of a preferred embodiment of the multi-stage sedimentation tank for wastewater from the production of organic fertilizer from Chinese medicinal herbs provided by this utility model; Figure 2 A top view schematic diagram of a preferred embodiment of the multi-stage sedimentation tank for wastewater from the production of organic fertilizer from Chinese medicinal herb residue provided by this utility model; Figure 3 for Figure 1 The diagram shows an enlarged view of part A.

[0018] The multi-stage sedimentation tank for wastewater from the production of organic fertilizer from Chinese medicinal herb residue includes: a primary sedimentation tank 1; a treatment tank 2, which is fixedly installed on one side of the primary sedimentation tank 1, and a partition 3 is fixedly installed inside the treatment tank 2, dividing the treatment tank 2 into a secondary sedimentation tank 4 and a tertiary sedimentation tank 5; a fixed column 6, which is fixedly installed inside the primary sedimentation tank 1 by a bracket, and has a drainage chamber 7 inside the fixed column 6, with a drainage port 9 connected to the drainage chamber 7; an inlet pipe 8, which is fixedly installed on the fixed column 6 and extends into the drainage chamber 7; a connecting port 10, which is located on the side connecting the primary sedimentation tank 1 and the treatment tank 2, and the connecting ports 10 are spaced apart; and a flow guiding mechanism, which is installed on the primary sedimentation tank 1 and is used to control the opening and closing of the connecting ports 10. The primary sedimentation tank 1 serves as a place for preliminary sedimentation of wastewater, which can perform preliminary suspended solids sedimentation treatment on the wastewater, reducing the difficulty of subsequent treatment. Treatment tank 2 is internally divided into a secondary sedimentation tank 4 and a tertiary sedimentation tank 5 by a partition 3, achieving multi-stage sedimentation of wastewater. This further removes suspended solids from the wastewater, improves the sedimentation effect, and allows for more thorough purification of the wastewater. The placement of the fixed column 6, the drain chamber 7, and the drain outlet 9, along with their connection to the inlet pipe 8, ensures that wastewater enters the primary sedimentation tank 1 evenly, avoiding concentrated entry and localized impacts, which is beneficial for the sedimentation of suspended solids. Simultaneously, the bottom of the drain chamber 7 is conical, facilitating the guidance of wastewater entering the chamber. By rationally setting the position and number of connecting ports 10, the flow rate and velocity of wastewater entering treatment tank 2 from the primary sedimentation tank 1 can be controlled, ensuring stable flow of wastewater between different sedimentation tanks and further improving sedimentation efficiency. The flow guiding mechanism can flexibly adjust the opening degree of the connecting ports 10 according to the sedimentation status of the wastewater in the primary sedimentation tank 1, ensuring that the wastewater is fully settled in the primary sedimentation tank 1 before entering treatment tank 2, effectively improving the treatment effect and stability of the entire multi-stage sedimentation tank.

[0019] The flow guiding mechanism includes a sealing plate 11, a connecting port 12, a fixing plate 13, and an electric telescopic rod 14. The sealing plate 11 is slidably installed on the primary sedimentation tank 1 and is correspondingly arranged with the connecting port 10. The connecting port 12 is opened on the sealing plate 11 and is correspondingly arranged with the connecting port 10 at intervals. The fixing plate 13 is fixedly installed on the sealing plate 11, and the electric telescopic rod 14 is fixedly installed on the treatment tank 2. The output shaft of the electric telescopic rod 14 is fixedly connected to the fixing plate 13. The sealing plate 11 can slide under the drive of the electric telescopic rod 14, thereby realizing the opening or closing control of the connecting port 10. It is one of the core components of the flow guiding mechanism and provides a basis for precise control of wastewater flow. The setting of the connecting port 12 allows the sealing plate 11 to control the actual opening area of ​​the connecting port 10 by adjusting the relative position of the connecting port 12 and the connecting port 10 during the sliding process, thereby precisely adjusting the flow rate of wastewater from the primary sedimentation tank 1 into the treatment tank 2 and ensuring that the wastewater has sufficient sedimentation time in the primary sedimentation tank 1. Through the fixed plate 13, the electric telescopic rod 14 can accurately transmit power to the sealing plate 11, achieving reliable sliding control of the sealing plate 11. As a power source, the electric telescopic rod 14 can precisely control the extension and retraction length of the output shaft according to a preset program or actual needs, thereby driving the sealing plate 11 to slide and achieving flexible adjustment of the opening and closing degree of the connecting port 10.

[0020] The bottom of the partition 3 has a flow port 15, and a baffle 16 is fixedly installed inside the tertiary sedimentation tank 5, with the baffle 16 corresponding to the flow port 15. The flow port 15 at the bottom of the partition 3 provides a channel for the flow of wastewater between the secondary sedimentation tank 4 and the tertiary sedimentation tank 5, avoiding large turbulence during the flow of wastewater, which is conducive to the deposition of sediments at the bottom of the tank, reduces the re-suspension of already settled substances, and further improves the sedimentation effect. The baffle 16 can change the flow direction of wastewater, so that the wastewater forms a specific water flow path in the tertiary sedimentation tank 5, prolonging the residence time of wastewater in the secondary sedimentation tank 5, allowing suspended solids in the wastewater more time to settle, further removing impurities from the wastewater and improving the quality of the effluent.

[0021] A support plate 17 is fixedly installed on the partition 3, and a blower 18 is fixedly installed on the support plate 17. A three-way pipe 19 is fixedly installed at the exhaust end of the blower 18, and an exhaust pipe 20 is fixedly installed on the three-way pipe 19. The exhaust pipe 20 has air holes, which are corresponding to the secondary sedimentation tank 4. The support plate 17 provides a stable mounting platform for the blower 18, ensuring its stability during operation. The blower 18 generates a strong airflow, providing power for subsequent treatment. The three-way pipe 19 allows the airflow generated by the blower 18 to be evenly distributed to each exhaust pipe 20. The air holes on the exhaust pipes 20 correspond to the secondary sedimentation tank 4; when the airflow exits from the air holes, it can blow away the floating matter above the secondary sedimentation tank 4, causing it to move in the same direction and preventing it from entering the tertiary sedimentation tank 5.

[0022] A rotating base 21 is fixedly installed at the bottom of the fixed column 6, and a scraper 22 is fixedly installed on the rotating base 21. The scraper 22 slides in contact with the bottom of the primary sedimentation tank 1. A rotary motor 23 is fixedly installed inside the fixed column 6, and the output shaft of the rotary motor 23 is fixedly connected to the rotating base 21. When the rotary motor 23 is started, its output shaft drives the rotating base 21 to rotate, thereby causing the scraper 22 to make circular motion at the bottom of the primary sedimentation tank 1. The scraper 22 can scrape up the sediment accumulated at the bottom of the primary sedimentation tank 1 and push it to the vicinity of the preset sludge discharge port, facilitating timely discharge of the sediment. This effectively solves the problem of difficult sediment cleaning at the bottom of traditional sedimentation tanks, avoids long-term sediment accumulation occupying the effective volume of the sedimentation tank, ensures the normal operation and sedimentation efficiency of the sedimentation tank, extends the service life of the sedimentation tank, and reduces maintenance costs.

[0023] A base 24 is fixedly installed at the bottom of the primary sedimentation tank 1. The base 24 is rotatably connected to the rotating seat 21. A ball bearing 25 is embedded at the end of the base 24 that contacts the rotating seat 21, and the ball bearing 25 contacts the rotating seat 21. The base 24 provides a stable support foundation for the rotating seat 21, ensuring the stability of the rotating seat 21 during rotation and preventing the scraper 22 from malfunctioning due to shaking of the rotating seat 21, thus affecting the sludge removal effect. When the rotating seat 21 rotates, the ball bearing 25 can roll, changing the original sliding friction into rolling friction. This change in friction mode greatly reduces the friction between the rotating seat 21 and the base 24, reduces energy loss, and improves the service life of the rotary motor 23. At the same time, the lower friction also makes the rotation of the rotating seat 21 smoother, and the scraper 22 can complete the sludge removal work more stably and efficiently, further improving the overall performance and operational stability of the multi-stage sedimentation tank.

[0024] A drain pipe is fixedly installed outside the primary sedimentation tank 1 and the treatment tank 2. A protective cover is fixedly installed on the support plate 17, and the protective cover covers the blower 18. The drain pipe provides a convenient channel for the discharge of sediment in the sedimentation tank, allowing the sediment to be discharged from the tank periodically, maintaining the effective volume of the sedimentation tank, ensuring the continuous and stable operation of the sedimentation tank, improving sedimentation efficiency, and facilitating centralized waste treatment and resource utilization. The protective cover provides all-round protection for the blower 18, effectively preventing harmful substances from entering the blower 18, preventing corrosion and damage to key components such as the motor and impeller of the blower 18, extending the service life of the blower 18, and reducing equipment maintenance costs.

The content protected by this utility model does not involve any improvement to the software and methods.

The bottom flow opening of the baffle reduces turbulence in the wastewater flow, and the baffles inside the tertiary sedimentation tank extend the wastewater retention time, further removing suspended solids and improving the quality of the effluent.

[0027] The flow rate and velocity of wastewater entering the treatment tank from the primary sedimentation tank are controlled by the connecting port. The flow guiding mechanism adjusts the wastewater flow rate by sliding the sealing plate and adjusting the relative position of the interface and the connecting port to ensure sufficient sedimentation in the primary sedimentation tank. The electric telescopic rod provides flexible adjustment power.

[0028] The rotating base at the bottom of the fixed column drives the scraper to rotate, scraping up and pushing the sediment at the bottom of the primary sedimentation tank to the sludge discharge port. The base and ball bearings reduce friction, ensuring smooth rotation and maintaining the normal operation and sedimentation efficiency of the sedimentation tank. The drain pipe facilitates the discharge of sediment, maintaining the effective volume of the sedimentation tank; the protective cover protects the blower, extends its service life, and improves the practicality and reliability of the equipment.
