[0027] The present invention also provides a method for treating and purifying water-polluted water bodies, including the following steps:

[0028] S1: When sewage needs to be treated, the sewage flows into the interior of the treatment tank through the water inlet tank. At this time, the system starts the first motor and the second motor to start preparing for treatment. The first motor drives the rotating shaft to start, and the rotating shaft starts to rotate in the treatment tank to prepare for the stirring process;

[0029] S2: The rotation of the rotating shaft drives the stirring blades to rotate uniformly in the treatment tank. The rotation of the stirring blades helps to uniformly mix the sewage in the treatment tank. At the same time, chemical agents are put into the feed hopper through the automatic control system to prepare for the subsequent treatment process;

[0030] S3: Subsequently, the second motor starts to work, driving the auger to rotate. The auger pushes the chemical agents through the feed hopper into the conveying cylinder. The conveying cylinder introduces the chemical agents into the treatment tank to ensure that the agents are evenly distributed in the sewage. The auger pushes the agents into the treatment tank through one side of the conveying cylinder;

[0031] S4: Meanwhile, the first motor continues to operate, driving the driving wheel to rotate. The driving wheel drives another driving wheel to rotate synchronously through the belt. The rotation of the driving wheel causes the connecting shaft to start rotating, and the connecting shaft drives the reciprocating lead screw to move reciprocally within the fixed plate. The movement of the reciprocating lead screw drives the cross plate to move horizontally synchronously through the threaded nut;

[0032] S5: The movement of the cross plate prompts the conveying cylinder to move smoothly in the horizontal direction. This action ensures that the chemical agent can be evenly distributed within the treatment tank. Through this precise control, it is ensured that the chemical agent is fully mixed with the sewage, achieving the effect of purification treatment.

[0033] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0034] 1. In the present invention, when sewage needs to be treated, after the sewage enters the interior of the treatment tank, the first motor and the second motor are started. The first motor drives the rotating shaft to rotate within the treatment tank, and the rotating shaft further drives the stirring blades to rotate evenly within the treatment tank. At this time, the chemical agent is put into the feed hopper. Subsequently, the second motor drives the auger to operate, and the chemical agent enters the conveying cylinder through the feed hopper. The auger pushes the agent to the treatment tank through one side of the conveying cylinder. Meanwhile, the first motor drives the driving wheel to rotate, the driving wheel drives the belt and another driving wheel to rotate synchronously, thereby causing the connecting shaft to rotate. The connecting shaft drives the reciprocating lead screw to move within the fixed plate, the reciprocating lead screw pushes the threaded nut to move, and the threaded nut drives the cross plate to move synchronously, thereby enabling the conveying cylinder to move smoothly in the horizontal direction. In this way, the chemical agent can be evenly distributed within the treatment tank. Through the continuous stirring of the stirring blades, the chemical agent is fully mixed with the sewage, achieving the purification effect. Finally, the treated water is sucked into the outlet water tank by the water pump and discharged through the outlet valve.

[0035] 2. In the present invention, when the sewage enters, it first enters the system through the water inlet housing and then flows through the inclined filter plate for preliminary filtration. The water flow after preliminary filtration enters the water inlet tank. The inclined filter plate effectively blocks solid waste, intercepts it, and concentrates it into the receiving box. When the filter plate needs to be cleaned, simply pull the handle to drive the filter plate to slide along the chute, and it can be easily taken out for replacement or cleaning.

[0036] 3. In the present invention, after the chemical agent is discharged, the return spring exerts an elastic force on the pressing plate, forcing the pressing plate to apply pressure to the interior of the feed hopper. This mechanism ensures that the chemical agent can enter the conveying cylinder quickly and smoothly, avoiding the accumulation of the agent in the feed hopper and ensuring the continuous supply of the agent.

[0054] The present invention also provides a method for treating and purifying water polluted by water environment, including the following steps:

[0055] S1: When sewage needs to be treated, the sewage flows into the interior of the treatment tank 2 through the water inlet tank 1. At this time, the system starts the first motor 72 and the second motor 806 and begins to prepare for treatment. The first motor 72 drives the rotating shaft 73 to start, and the rotating shaft 73 begins to rotate inside the treatment tank 2, preparing to start the stirring process;

[0056] S2: The rotation of the rotating shaft 73 drives the stirring blades 74 to rotate uniformly inside the treatment tank 2. The rotation of the stirring blades 74 helps to uniformly mix the sewage inside the treatment tank 2. At the same time, chemical agents are put into the feed hopper 809 through the automatic control system to prepare for the subsequent treatment process;

[0057] S3: Subsequently, the second motor 806 starts to work, driving the auger 808 to rotate. The auger 808 pushes the chemical agents through the feed hopper 809 into the conveying cylinder 807. The conveying cylinder 807 introduces the chemical agents into the treatment tank 2 to ensure that the agents are evenly distributed into the sewage. The auger 808 pushes the agents into the treatment tank 2 through one side of the conveying cylinder 807;

[0058] S4: At the same time, the first motor 72 continues to operate, driving the transmission wheel 75 to rotate. The transmission wheel 75 drives another transmission wheel 75 to rotate synchronously through the belt 76. The rotation of the transmission wheel 75 causes the connecting shaft 77 to start rotating. The connecting shaft 77 drives the reciprocating lead screw 803 to perform a reciprocating motion inside the fixed plate 801. The motion of the reciprocating lead screw 803 drives the cross plate 805 to move horizontally synchronously through the threaded nut 804;

[0059] S5: The movement of the cross plate 805 prompts the conveying cylinder 807 to move smoothly in the horizontal direction. This action ensures that the chemical agent can be evenly distributed in the treatment tank 2. Through this precise control, it is ensured that the chemical agent is fully mixed with the sewage, achieving the effect of purification treatment.

[0060] Working principle: When in use, when sewage needs to be treated, the sewage first flows into the interior of the treatment tank 2. Subsequently, the first motor 72 and the second motor 806 are started. The first motor 72 drives the rotating shaft 73 to rotate, and the rotating shaft 73 drives the stirring blades 74 to rotate evenly in the treatment tank 2. At the same time, the chemical agent is put into the feed hopper 809. The second motor 806 drives the auger 808 to rotate, and the chemical agent enters the conveying cylinder 807 through the feed hopper 809. The auger 808 pushes the chemical agent into the treatment tank 2 through one side of the conveying cylinder 807. At the same time, the first motor 72 drives the transmission wheel 75 to rotate, and the transmission wheel 75 drives the belt 76 and another transmission wheel 75 to rotate synchronously, thereby causing the connecting shaft 77 to rotate. The connecting shaft 77 drives the reciprocating screw rod 803 to move in the fixed plate 801, pushing the threaded nut 804 to move. The threaded nut 804 drives the cross plate 805 to move synchronously, and then the conveying cylinder 807 moves smoothly in the horizontal direction, ensuring that the chemical agent can be evenly distributed in the treatment tank 2. Through the continuous stirring of the stirring blades 74, the chemical agent is fully mixed with the sewage. Subsequently, the treated water is sucked into the water outlet tank 3 by the water pump 4 and discharged through the water outlet valve 11. When the sewage enters the system, it first enters through the water inlet housing 93 and flows through the inclined filter plate 95 for preliminary filtration. The solid waste is blocked by the filter plate 95 and concentrated and falls into the receiving box 92. When the filter plate 95 needs to be cleaned, it can be made to slide along the chute 94 by pulling the handle 96, which is convenient for replacement or cleaning. Finally, when the chemical agent is discharged, the return spring 813 exerts an elastic force on the pressing plate 811, forcing the pressing plate 811 to apply pressure to the feed hopper 809, ensuring that the chemical agent enters the conveying cylinder 807 quickly and smoothly. Thus, the process of putting and fully stirring the chemical agent is completed.

[0061] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.

The connecting shaft (77) drives the reciprocating lead screw (803) to perform a reciprocating motion in the fixed plate (801). The movement of the reciprocating lead screw (803) drives the cross plate (805) to move synchronously in the horizontal direction through the threaded nut (804). S5: The movement of the cross plate (805) causes the conveying cylinder (807) to move smoothly in the horizontal direction. This action ensures that the chemical agent can be evenly distributed in the treatment tank (2). Through this precise control, it is ensured that the chemical agent is fully mixed with the sewage to achieve the effect of purification treatment.
