Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically an SBR reactor. Background Technology

[0002] SBR (Sequencing Batch Reactor) wastewater treatment technology is a highly efficient, flexible, and stable wastewater treatment technology. It integrates functions such as equalization tanks, primary sedimentation tanks, biological oxidation, and secondary sedimentation tanks into one system, eliminating the need for a sludge return system. Through cyclical stages of influent, aeration, sedimentation, effluent discharge, and standby, it effectively treats wastewater. The SBR process offers advantages such as small footprint, strong adaptability, stable treatment performance, and good effluent quality, making it particularly suitable for small to medium-sized wastewater treatment plants and intermittent industrial wastewater discharge. Furthermore, the SBR process features a robust automation system and effective nitrogen and phosphorus removal, meeting stringent discharge standards.

[0003] In the SBR (Sequencing Batch Reactor) wastewater treatment process, a mixer is typically used to ensure thorough mixing and reaction of the wastewater. The core component of the mixer is the impeller, which needs to be immersed in the wastewater for extended periods to guarantee uniform mixing. However, wastewater contains various corrosive substances such as acids, alkalis, and salts, which can severely corrode and damage the impeller. Over time, these corrosive substances gradually erode the impeller surface, leading to a decrease in impeller strength and durability. Ultimately, the impeller may develop cracks, deform, or even break, affecting the normal operation of the mixer and consequently impacting the efficiency and effectiveness of the entire wastewater treatment system.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2As shown, this utility model provides a technical solution for an SBR reactor, including a reactor body 1, a circulation pipe 3 on the reactor body 1, an outlet pipe 2 at one edge of the reactor body 1, an inlet pipe 4 at the other edge of the reactor body 1, an aeration pipe 5 at the bottom of the reactor body 1, an inner partition wall panel 6 inside the reactor body 1, a stirring mechanism 7 on the reactor body 1, and a lifting mechanism 8 at the bottom of the mechanism housing 704. Through the combined use of the stirring mechanism 7 and the lifting mechanism 8, the stirring blades 707 can be removed from the sewage when stirring stops, reducing the risk of corrosion of the stirring blades 707 and extending the service life of the stirring blades 707.

[0022] like Figure 2 and Figure 3 As shown, the stirring mechanism 7 includes a housing 704 disposed above the main body 1 of the reaction tank. A stirring shaft 706 is movably mounted on the bottom of the housing 704. A stirring blade 707 is fixedly mounted on the lower end of the stirring shaft 706. A transmission shaft 703 is movably mounted inside the housing 704. A drive motor 701 is fixedly mounted on one end of the housing 704. A drive shaft 702 is provided at the output end of the drive motor 701, and one end of the drive shaft 702 is fixed on the transmission shaft 703. Both the transmission shaft 703 and the stirring shaft 706 are provided with helical gears 705, and the two sets of helical gears 705 mesh together. A coupling is provided at the output end of the drive motor 701, and the drive shaft 702 is fixed to the output end of the drive motor 701 through the coupling.

[0023] Specifically, the drive motor 701 can drive the drive shaft 702 to rotate, and the drive shaft 702 will drive the transmission shaft 703 to rotate. The transmission shaft 703 will drive the stirring shaft 706 to rotate, and the stirring shaft 706 will drive the stirring blades 707 to rotate, thereby stirring the sewage in the main body of the reaction tank 1.

[0024] like Figure 3 and Figure 4 As shown, the lifting mechanism 8 includes a positioning sleeve 801 and a positioning base 804 fixedly installed on the reaction tank body 1. A positioning guide rod 802 is movably installed inside the positioning sleeve 801, and the upper end of the positioning guide rod 802 is fixed on the mechanism housing 704. An electric push rod 806 is fixedly installed on the positioning base 804. A plastic protective sleeve 807 is fitted on the electric push rod 806. A docking support leg 803 is fixedly installed at the output end of the electric push rod 806. A positioning through hole 805 is opened at the edge of the positioning base 804. A bolt is provided in the positioning through hole 805, and the positioning base 804 is fixed to the upper end of the reaction tank body 1 by bolts. A through hole is opened on the upper surface of the reaction tank body 1, and the positioning guide rod 802 extends into the reaction tank body 1 through the through hole.

[0025] Specifically, after the electric push rod 806 is retracted, the stirring blade 707 will be immersed in the sewage to stir the sewage. After the electric push rod 806 is extended, it will drive the mechanism housing 704 to move upward, thereby driving the stirring blade 707 to move upward. When stirring stops, the stirring blade 707 will leave the sewage, reducing the risk of corrosion of the stirring blade 707 and extending the service life of the stirring blade 707.

[0026] Working principle: During use, sewage enters the main body 1 of the reaction tank through the inlet pipe 4. After the sewage enters the main body 1 of the reaction tank, the drive motor 701 can be started. After the drive motor 701 is started, it will drive the drive shaft 702 to rotate. After the drive shaft 702 rotates, it will drive the transmission shaft 703 to rotate. Under the action of the helical gear 705, the transmission shaft 703 can drive the stirring shaft 706 to rotate. After the stirring shaft 706 rotates, it will drive the stirring blade 707 to rotate, thereby stirring the sewage in the main body 1 of the reaction tank. When stirring stops, the electric push rod 806 can be controlled to extend. After the electric push rod 806 extends, it will drive the mechanism housing 704 to move upward. After the mechanism housing 704 moves upward, it will drive the stirring blade 707 at the lower end of the stirring shaft 706 to move upward. When stirring stops, the stirring blade 707 is removed from the sewage, reducing the risk of corrosion of the stirring blade 707 and extending the service life of the stirring blade 707.
