By fixing the lower end of the motor bracket 362 on the top of the sealing cover 2, the stable installation and support of the motor 361 are ensured, and a reliable power source is provided for the stirring mechanism 3, thereby ensuring the stirring effect in the wastewater treatment process and the smooth progress of the subsequent impurity cleaning work.

[0045] In specific use, the working principle of the utility model is as follows:

[0046] Firstly, the operator can safely open the sealing cover 2 and pour the wastewater containing ammonia into the recovery tank 1.

[0047] Then, according to the actual concentration of ammonia in the wastewater and the treatment requirements, the operator needs to accurately calculate and add a corresponding amount of solution containing specific metal ions (such as magnesium ions, calcium ions, etc.) and phosphate. The selection and addition amount of these solutions are crucial because they will chemically react with the ammonium ions in the wastewater to form ammonium phosphate double salt precipitate.

[0048] After the wastewater and the chemical solution are added, the sealing cover 2 is quickly closed, and its sealing performance is checked to ensure that a closed reaction environment is formed inside the device. At this time, the electric telescopic rod 44 is in its initial retracted state, and the cleaning plate 47 and the soft brush (made of wear-resistant and elastic nylon material) thereon are not in contact with the bottom of the inner cavity of the recovery tank 1, and are in a suspended state. This design can avoid any unnecessary interference of the brush to the chemical reaction to be performed.

[0049] Next, the motor 361 in the power assembly 36 is started. The motor 361 is connected to the driving wheel 35 through the belt 34. When the motor 361 rotates, it drives the driving wheel 35 to rotate, and then drives the driven wheel 33 to rotate through the transmission action of the belt 34. The rotation of the driven wheel 33 drives the hollow shaft 31 fixedly connected thereto to rotate. The hollow shaft 31 has the stirring piece 32 fixedly installed on the outer side thereof, and the stirring blades 322 (four in number, uniformly distributed in a circumferential shape) on the stirring piece 32 generate strong vortex in the wastewater. This vortex not only promotes the mixing of the ammonium ions in the wastewater with the solution containing specific metal ions and phosphate, but also accelerates the chemical reaction between them, ensuring the rapid formation of ammonium phosphate double salt precipitate.

[0050] After the chemical reaction is completed, the ammonium phosphate double salt precipitate and other impurities will be deposited at the bottom of the recovery tank 1. At this time, the power assembly 36 is turned off, the stirring is stopped, and a period of time is waited for the precipitate to fully settle.

[0051] Subsequently, in order to clean the impurity deposits, the electric telescopic rod 44 is started again. The output end of the electric telescopic rod 44 extends downward, driving the movable rod 45, the elastic assembly 46 and the cleaning plate 47 to move downward together until the soft brush at the bottom of the cleaning plate 47 is in close contact with the bottom of the inner cavity of the recovery tank 1. During the cleaning process, the motor 361 is started again, and through the transmission of the belt 34, the driving wheel 35 and the driven wheel 33, the hollow shaft rod 31 continues to rotate at a lower speed. Since the cleaning plate 47 is in close contact with the bottom of the recovery tank 1, the rotation of the hollow shaft rod 31 will drive the cleaning plate 47 and the soft brush thereon to make a circular motion at the bottom of the recovery tank 1. The softness and elasticity of the soft brush ensure that it can gently and effectively clean the impurity deposits deposited at the bottom, while avoiding damage to the bottom of the recovery tank 1.

[0052] During the cleaning process, the telescopic spring 461 and the elastic rod 462 in the elastic assembly 46 play a key role. They not only ensure that the cleaning plate 47 can maintain a certain pressure during the cleaning process, so that the soft brush can be closely attached to the bottom of the recovery tank 1, but also can adapt to different thicknesses of the impurity deposit layer. When encountering a thicker impurity layer, the telescopic spring 461 and the elastic rod 462 can be elastically deformed, thereby avoiding excessive pressure on the bottom of the recovery tank 1 and ensuring the uniformity and thoroughness of the cleaning.

[0053] After the cleaning is completed, the motor 361 is turned off, and a period of time is waited for the cleaning plate 47 and the soft brush thereon to stop moving. Subsequently, the electric telescopic rod 44 is retracted, driving the cleaning plate 47 and the soft brush thereon to return to the initial suspended state. At this time, the operator can safely open the sealing cover 2 and use appropriate tools or equipment to take out the treated deposits (mainly ammonium phosphate double salt deposits) for subsequent processing or recycling.

[0054] In summary, the ammonia-containing wastewater recycling device realizes efficient treatment of ammonia-containing wastewater and recycling of ammonia resources by controlling the addition amount of chemical solution, optimizing the design of the stirring and cleaning process, and adopting innovative technologies such as soft brushes that are wear-resistant and have a certain elasticity, etc. At the same time, the cleaning process of the impurity deposits is simplified, and the operation difficulty and cost are reduced.

[0055] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited thereto. Any simple change, equivalent replacement or modification made on the basis of the present application to solve basically the same technical problem and achieve basically the same technical effect is covered by the protection scope of the present application.
