Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a multi-stage wastewater treatment tank. Background Technology

[0002] The working principle of a wastewater treatment tank is as follows: Physical treatment: Large suspended solids and floating objects, such as branches and plastic bottles, are intercepted in the wastewater through a screen to prevent them from entering subsequent treatment units and causing blockages or damage to the equipment. After the wastewater enters the primary sedimentation tank, large solid particles will settle to the bottom under gravity, forming sludge, which can remove a considerable portion of suspended solids and reduce the burden on subsequent treatment. Biological treatment: Microorganisms decompose organic matter in the wastewater and remove pollutants such as nitrogen and phosphorus. For example, a biofilm method is used, where microorganisms attach to a carrier to form a biofilm. The equipment is set up with anoxic and aerobic zones. In the anoxic zone, microorganisms remove nitrogen compounds in the wastewater through denitrification, while in the aerobic zone, microorganisms further decompose organic matter through oxidation. Chemical treatment: Sometimes chemical agents, such as flocculants and disinfectants, are added to the wastewater. Flocculants can cause fine particles in the wastewater to agglomerate into larger particles, which are easier to settle and separate. Disinfectants are used to kill pathogenic microorganisms in the wastewater to ensure the safety of the effluent.

[0003] Existing wastewater treatment tanks require the addition of chemicals to purify the wastewater during use. To ensure the mixing effect of the chemicals, an additional stirring mechanism is needed. However, existing wastewater treatment tanks do not remove large impurities before adding chemicals to the wastewater, which makes the stirring structure prone to impact damage and reduces the mixing efficiency of wastewater and chemicals. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage sewage treatment tank to solve the problem mentioned in the background art that existing sewage treatment tanks do not remove large impurities before adding chemicals to the sewage, which makes the mixing structure prone to impact damage and reduces the mixing efficiency of sewage and chemicals.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage sewage treatment tank, comprising a tank body with a maintenance sealing door rotatably mounted on its front surface; a feed pipe fixedly connected to the upper surface of the tank body; a filter baffle fixedly connected to the inner wall of the upper cavity of the tank body; a drainage opening on the surface of the filter baffle; a debris cleaning pipe fixedly connected to the upper side surface of the tank body; a material distribution block fixedly connected to the inner wall of the cavity of the tank body; guide openings on the outer surfaces of both ends of the material distribution block; a drive motor fixedly connected to the upper surface of the tank body; a transmission cylinder mounted on the top surface of the cavity of the tank body; a transmission gear mounted on the upper surface of the material distribution block; a first stirring column fixedly connected to the lower surface of the transmission gear; a chemical spraying pipe fixedly connected to the inner wall of the lower cavity of the tank body; a discharge opening on the lower surface of the tank body; and a linkage stirring mechanism inside the material distribution block, which drives two linkage gears and a second stirring column to rotate via the transmission gear to facilitate the stirring of sewage.

[0006] Preferably, the feed pipe is connected to the cavity of the processing box body, the filter baffle is inclined, and the drainage openings are evenly distributed on the surface of the filter baffle.

[0007] The above technical solution ensures that sewage can smoothly enter the treatment tank through the feed pipe, guaranteeing the continuity of the sewage treatment process. This is a key connection design for sewage entering the treatment tank.

[0008] Preferably, the material distribution mounting block is symmetrically designed, and the upper surface of the material distribution mounting block is inclined. The guide openings are arranged in a straight line and penetrate through the upper and lower surfaces of the material distribution mounting block.

[0009] By adopting the above technical solution, the symmetrical design can ensure that the sewage is more evenly distributed on both sides of the distribution block, avoiding the sewage from being biased to one side and causing uneven treatment. The inclined design of the upper surface can use gravity to guide the pre-treated sewage to the guide opening, improve the smoothness of sewage flow and reduce stagnation.

[0010] Preferably, the transmission cylinder is rotatably connected to the processing box body, the upper end of the transmission cylinder is fixedly connected to the output end of the drive motor, and the transmission cylinder is rotatably connected to the filter baffle.

[0011] By adopting the above technical solution, the transmission cylinder can rotate flexibly, providing a foundation for subsequent power transmission, ensuring the smoothness of the power transmission process, and reducing power loss caused by factors such as friction.

[0012] Preferably, the transmission gear is rotatably connected to the material distribution mounting block, and the upper end of the transmission gear penetrates the surface of the material distribution mounting block. The upper end of the transmission gear is fixedly connected to the transmission cylinder. The lower end of the first stirring column penetrates the lower surface of the material distribution mounting block. A medicine pipe connected to the medicine spraying pipe is provided on the rear surface of the treatment box body.

[0013] The above technical solution enables the transmission gear to rotate flexibly on the material distribution mounting block, providing conditions for connection with the transmission cylinder and driving other gears to rotate. The through-type design facilitates the connection between the transmission gear and the transmission cylinder.

[0014] Preferably, the linkage stirring mechanism includes linkage gears, two linkage gears are installed inside the material distribution mounting block, and two second stirring columns are installed on the lower surface of the material distribution mounting block.

[0015] The above technical solution clarifies the composition of the linkage mixing mechanism, which includes two linkage gears and two second mixing columns. By setting multiple mixing columns, the mixing range and mixing force of the sewage can be increased.

[0016] Preferably, the linkage gear and the material distribution mounting block are rotatably connected, the linkage gear and the transmission gear are meshingly connected, the second stirring column and the material distribution mounting block are rotatably connected, and the rotating shaft of the second stirring column is fixedly connected to the rotating shaft of the linkage gear.

[0017] By adopting the above technical solution, it is ensured that the linkage gear can rotate flexibly, providing a basis for its cooperation with the transmission gear and for driving the second stirring column to rotate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This multi-stage sewage treatment tank:

[0019] 1. Effectively intercepts large impurities, protecting downstream equipment. Through the inclined filter baffle and evenly distributed drainage openings, large impurities in the wastewater are intercepted and slide along the inclined surface towards the impurity cleaning pipe for discharge, preventing impurities from impacting the mixing structure and causing damage, thus extending the equipment's service life.

[0020] 2. The linkage stirring mechanism drives the linkage gear through the transmission gear, so that the first stirring column and the second stirring column rotate synchronously, expanding the stirring range. This, combined with the uniform spraying of the agent through the agent spraying pipe, ensures that the wastewater and the agent come into full contact, thereby improving the purification effect.

[0021] 3. The symmetrical inclined design of the material distribution installation block and the straight-lined guide openings guide the sewage to enter the next stage of treatment evenly; the connection design between the feed pipe and the treatment tank body ensures continuous sewage input and improves the overall treatment efficiency.
