The motor 17 provides power, slows down the speed and increases the torque through the reducer 18, drives the rotating shaft 3 to rotate, and thus realizes the stirring function.

[0024] In a further preferred embodiment of the present invention, the filtering assembly includes two support plates 9, a collecting box 7, a filter screen 8 and a baffle 10, the two support plates 9 are installed in the processing tank body 1, the collecting box 7 is placed on the top of the two support plates 9 and can extend to the outside of the processing tank 1, the filter screen 8 is arranged at the bottom of the collecting box 7, the collecting box 7 is located directly below the guide hopper 2, the baffle 10 is installed on the collecting box 7 and is located outside the processing tank 1, and the baffle 10 is in contact with the outer wall of the processing tank 1.

[0025] In this embodiment, the support plate 9 provides stable support for the collecting box 7, ensuring that the collecting box 7 and the filter screen 8 inside it can be firmly placed in the processing tank 1, while facilitating the removal and cleaning of the collecting box 7. The collecting box 7 facilitates the collection and removal of sediment. The collecting box 7 is located directly below the guide hopper 2, ensuring that the sediment can fall directly into the collecting box 7. Through the filtering effect of the filter screen 8, the sediment and wastewater are effectively separated to avoid waste liquid contamination of the sediment. At the same time, the purity of the sediment is ensured, and wastewater is prevented from flowing out from the gap between the collecting box 7 and the processing tank 1, causing environmental pollution or affecting processing efficiency.

As a channel for wastewater transportation, it ensures that the wastewater can be smoothly extracted from the processing tank 1 and transported to the waste liquid tank 13. The limit plate 16 can contact the top of the processing tank 1 to limit the insertion depth of the liquid inlet pipe 15, preventing the liquid inlet pipe 15 from being over-inserted into the processing tank 1, causing pipeline blockage or damage, and at the same time ensuring that the liquid inlet pipe 15 can stay stably in the appropriate position.

[0028] In a further preferred embodiment of the present invention, a water tank 20 is installed on the side of the processing tank 1 away from the waste liquid tank 13, and an output pump 21 is provided in the water tank 20. The discharge end of the output pump 21 extends into the processing tank 1, and a cleaning pipe 22 is installed in the processing tank 1. The cleaning pipe 22 is connected to the discharge end of the output pump 21, and a plurality of discharge ports are provided on the cleaning pipe 22.

Through the coordinated use of the output pump 21 and the cleaning pipe 22, the inner wall of the processing tank 1 and the filter assembly and other components are quickly and evenly cleaned, thereby improving the cleaning efficiency and effect. At the same time, the mixture of clean water and sediment can wash away the residual chemicals on the sediment and purify the sediment.

[0030] In a further preferred embodiment of the present invention, the outer fixed sleeve of the electric telescopic rod 4 is provided with a rubber protective sleeve 12, and two clamping plates 11 that can contact the baffle 10 are rotatably installed on the outer wall of the processing tank 1, and a handle is fixed on the baffle 10.

[0031] In this embodiment, the rubber protective cover 12 plays a role in protecting the electric telescopic rod 4, preventing it from being worn or impacted during operation, thereby extending its service life. At the same time, the rubber protective cover can also provide a certain buffering and shock-absorbing effect, reducing the noise and vibration of the electric telescopic rod 4 during operation. Through the contact between the card plate 11 and the baffle 10, the baffle 10 is firmly fixed, ensuring that wastewater does not flow out from the gap between the collection box 7 and the processing tank 1. At the same time, the rotating design of the card plate 11 makes the fixing and release of the baffle 10 more convenient and quick, and the handle provides a convenient gripping point for the operator, making the opening and closing of the baffle 10 easier.

[0032] In a further preferred embodiment of the present invention, the waste liquid tank 13 and the water tank 20 are both provided with observation windows, the waste liquid tank 13 and the bottom of the processing tank 1 are provided with a sewage pipe 23, both of the sewage pipes 23 are provided with valves, and the tops of the processing tank 1 and the water tank 20 are both provided with a liquid replenishing pipe 19, and protective covers are removably installed on both of the liquid replenishing pipes 19.

[0033] In this embodiment, the observation window allows the operator to intuitively observe the liquid level in the waste liquid tank 13 and the water tank 20, so as to replenish water or discharge waste liquid in time to ensure the normal operation of the equipment. The sewage pipe 23 realizes the rapid and convenient discharge of waste liquid and cleaning waste water, avoiding the waste liquid from being retained in the equipment for a long time, causing environmental pollution or equipment damage. The refill pipe 19 provides a convenient refill channel for the equipment, allowing the operator to replenish water into the processing tank 1 or the water tank 20 as needed to ensure the normal operation of the equipment.

[0034] In a further preferred embodiment of the present invention, a blocking block 6 is rotatably mounted on the bottom of the stirring rod 5 , and the blocking block 6 is used to close the discharge port. An elastic sleeve is fixed outside the blocking block 6 .

[0035] In this embodiment, during the preparation of the electrocatalyst, the stirring rod 5 plays the role of mixing and stirring the raw materials, ensuring that the raw materials are evenly mixed and improving the preparation efficiency. The block 6 is used to close the discharge port to prevent the raw materials or waste liquid from leaking from the discharge port during the stirring process, thereby ensuring the cleanliness and safety of the preparation process. At the same time, the rotation design of the block 6 enables the block 6 to easily open or close the discharge port when discharge is required. The elastic sleeve provides an additional sealing effect for the block 6, enhances the sealing between the block 6 and the discharge port, and further prevents the leakage of raw materials or waste liquid. At the same time, the elastic sleeve also has a certain buffering and shock-absorbing effect, reducing the friction and wear between the block 6 and the discharge port during rotation.

[0036] To sum up, compared with the relevant technology, this device can fully mix the raw materials of the electrocatalyst by setting the motor 17, the rotating shaft 3 and the stirring rod 5, and can extract the precipitated clear liquid in the precipitated raw materials by setting the waste liquid tank 13, the input pump 14 and the liquid inlet pipe 15, leaving the precipitate to enter the subsequent flushing work, and can flush the precipitate by setting the water tank 20, the output pump 21 and the cleaning pipe 22 to clean the residual agent on the precipitate, and can filter the precipitate by setting the collecting box 7, leaving the solid material.
