The sealing plate contacts the bottom of the inner wall of the feeding box, and the discharge pipe is sealed by the sealing plate.

[0014] A process for using a 2,4,5-trifluorophenylacetic acid hydrolysis wastewater recycling device comprises the following steps: Step 1: First, let the wastewater enter the sewage treatment tank through the water inlet pipe. When the sewage enters, the filter plate will filter the waste residue in the sewage to prevent excessive waste residue in the wastewater, which will affect the wastewater treatment and recovery efficiency. At the same time, the solution added into the feeding box will merge with the wastewater to improve the wastewater treatment effect; Step 2: The reciprocating screw is driven to rotate by the rotation of the motor, and the rotation of the reciprocating screw drives the stirring blade to rotate, and the wastewater and the solution are fully mixed by the rotation. At the same time, the rotation of the reciprocating screw drives the movable frame to reciprocate up and down, and the reciprocating movement of the movable frame drives the elastic telescopic rod to reciprocate up and down, and the reciprocating movement of the elastic telescopic rod drives the arc plate to reciprocate up and down, and the inner wall of the sewage treatment tank is scraped by the up and down reciprocating movement of the arc plate to prevent the waste residue from adhering to the inner wall of the sewage treatment tank, resulting in reduced reaction efficiency and affecting the wastewater treatment recovery efficiency; Step 3: The elastic telescopic rod reciprocates up and down to drive the short rod to reciprocate up and down. When the short rod moves down along the guide plate to the bottom of the guide groove, the elastic force of the elastic telescopic rod drives the arc plate to reset. The movable frame moves upward to drive the elastic telescopic rod and the short rod to move upward. The short rod moves downward to contact the rotating plate. The short rod pushes the rotating plate to rotate upward. When the rotating plate is separated from the short rod, the No. 1 torsion spring drives the rotating plate to reset. Step 4: The limit plate contacts the guide plate to limit the rotating plate. When the movable frame moves downward, driving the elastic telescopic rod and the short rod downward, the short rod contacts the rotating plate. The rotating plate causes the short rod to move along the direction of the rotating plate close to the inner wall of the sewage treatment tank. The short rod moves toward the inner wall of the sewage treatment tank, driving the elastic telescopic rod and the arc plate to move toward the inner wall of the sewage treatment tank, thereby preventing the arc plate from continuously scraping the inside of the sewage treatment tank, which reduces the service life of the sewage treatment tank.

[0015] The present invention provides a 2,4,5-trifluorophenylacetic acid hydrolysis wastewater recycling device and process, which has the following beneficial effects: (1) The invention filters the waste residue in the sewage through the filter plate to prevent excessive waste residue in the wastewater, which would affect the wastewater treatment and recovery efficiency. At the same time, the inner wall of the sewage treatment tank is scraped by the up and down reciprocating motion of the arc plate to prevent the waste residue from adhering to the inner wall of the sewage treatment tank, which would reduce the reaction efficiency and affect the wastewater treatment and recovery efficiency. The short rod moves toward the inner wall of the sewage treatment tank, which drives the elastic telescopic rod and the arc plate to move toward the inner wall of the sewage treatment tank, which prevents the arc plate from continuously scraping the inside of the sewage treatment tank, which would reduce the service life of the sewage treatment tank.

[0016] (2) In the present invention, the filter plate moves upward and contacts with the scraper, which scrapes off the waste residue attached to the filter plate and pushes it into the slag discharge frame to achieve the removal and discharge of the waste residue. The filter plate is cleaned intermittently to prevent the filter plate from being blocked and to increase the service life of the filter plate. At the same time, the triangular block contacts the fixed rod during rotation, and the fixed rod pushes the triangular block to rotate downward. The rotation of the triangular block drives the rotating plate to rotate upward. The rotating plate rotates upward so that the waste residue can be better pushed into the slag discharge frame, thereby improving the treatment effect of the waste residue.

[0017] (3) In the present invention, the upward movement of the circular plate will drive the long rod to move upward, and the upward movement of the long rod will drive the sealing plate to move upward. The upward movement of the sealing plate will release the limit on the discharge pipe, allowing the solution to flow into the discharge pipe. When the circular ring moves downward, it will lose support for the connecting plate, causing the connecting plate and the circular plate to move downward. The downward movement of the circular plate will open the discharge pipe, allowing a certain amount of solution in the discharge pipe to flow into the sewage treatment tank. By quantitatively adding the solution, continuous addition of the solution can be prevented, which would lead to increased costs. At the same time, the stirring rod can prevent the solution in the feeding box from precipitating, which would reduce the effect and affect the sewage treatment effect.

9. A process for using a 2,4,5-trifluorophenylacetic acid hydrolysis wastewater recycling device, using the 2,4,5-trifluorophenylacetic acid hydrolysis wastewater recycling device according to claim 8, characterized in that: The following steps are involved: Step 1: First, the wastewater is passed through the water inlet pipe (2) into the wastewater treatment tank (1). When the wastewater enters, the filter plate (4) filters the waste residue in the wastewater to prevent excessive waste residue in the wastewater from affecting the wastewater treatment and recovery efficiency. At the same time, the feeding box (5) feeds the solution to merge with the wastewater to improve the wastewater treatment effect. Step 2: The reciprocating screw (7) is driven to rotate by the motor (6), and the rotation of the reciprocating screw (7) drives the stirring blade (8) to rotate, so that the wastewater and the solution are fully mixed by the rotation. At the same time, the rotation of the reciprocating screw (7) drives the movable frame (9) to move up and down, and the up and down reciprocating movement of the movable frame (9) drives the elastic telescopic rod (12) to move up and down, and the up and down reciprocating movement of the elastic telescopic rod (12) drives the arc plate (13) to move up and down, and the up and down reciprocating movement of the arc plate (13) is used to scrape the inner wall of the sewage treatment tank (1) to prevent waste residue from adhering to the inner wall of the sewage treatment tank (1), resulting in reduced reaction efficiency and affecting the wastewater treatment recovery efficiency; Step 3: The elastic telescopic rod (12) reciprocates up and down, driving the short rod (15) to reciprocate up and down. When the short rod (15) moves downward along the guide plate (14) to the bottom of the guide groove, the elastic force of the elastic telescopic rod (12) drives the arc plate (13) to reset. The movable frame (9) moves upward, driving the elastic telescopic rod (12) and the short rod (15) to move upward. The short rod (15) moves downward and contacts the rotating plate (16). The short rod (15) pushes the rotating plate (16) to rotate upward. When the rotating plate (16) is separated from the short rod (15), the first torsion spring drives the rotating plate (16) to reset. Step 4: The limiting plate (17) contacts the guide plate (14) so ​​that the limiting plate (17) limits the rotating plate (16). When the movable frame (9) moves downward and drives the elastic telescopic rod (12) and the short rod (15) to move downward, the short rod (15) contacts the rotating plate (16). The rotating plate (16) causes the short rod (15) to move in the direction of the rotating plate (16) close to the inner wall of the sewage treatment tank (1). The short rod (15) moves in the direction close to the inner wall of the sewage treatment tank (1) and drives the elastic telescopic rod (12) and the curved plate (13) to move in the direction close to the inner wall of the sewage treatment tank (1), thereby preventing the curved plate (13) from continuously scraping the inside of the sewage treatment tank (1), thereby reducing the service life of the sewage treatment tank (1).
