[0015] The present invention also provides a method for using the sludge treatment equipment, comprising the following steps:

[0016] S1. The muddy water mixed with flocculants is injected into the mixing box through the water inlet pipe, and then enters the lifting cylinder through the bottom of the partition, and then overflows to the other side of the lifting cylinder through the lifting cylinder. The sewage pump is started, and the sewage pump conveys the muddy water to the water tank. After being guided by the funnel, it enters the extrusion cylinder. At the same time, the motor is started, and the motor drives the drive shaft and the extrusion blades to rotate. The extrusion blades push the sludge in the water to one end of the pressure plate. As the pressure of the sludge increases, the pressure plate is pushed open, thereby separating the mud and water;

[0017] S2. When the water flows through the water inlet pipe, the impact force of the water flow impacts the driving blade, and the driving blade rotates to drive the installation shaft to rotate, and the installation shaft drives the cam to rotate, and the cam pushes the first slide bar to move, and the first slide bar pulls the swing box to rotate through the support rod. When the swing box rotates upward, the floating objects or oil on the water surface on one side of the partition are lifted upward. After the swing box continues to rotate, the floating objects in the swing box are poured into the oil collection box for collection, which is convenient for people to collect. When the protruding position of the cam is away from the first slide bar, the swing box is reset, and then the floating objects are collected reciprocatingly;

[0018] S3. While the installation shaft is rotating, the rotating shaft is also driven to rotate by the pulley, and the rotating shaft drives the stirring blade to rotate. The stirring blade stirs the medium to improve the mixing effect of the medium and prevent sedimentation from occurring in the lifting cylinder;

[0019] S4. The water squeezed out by the extrusion blades is discharged after secondary filtration by the filter screen, while the water with poor cleanliness enters the sewage pipe. During the rotation of the driving shaft, the eccentric wheel is driven to rotate. The eccentric wheel cooperates with the second spring to drive the second slide bar to move back and forth, and drives the piston to move. When the piston moves to one side of the mixing box, the medium in the pressure pipe is pushed into the mixing box for circulation treatment, thereby reducing the discharge of sewage and improving the quality of discharged water. When the piston is reset, the rubber sheet in the pressure pipe is closed, and the other rubber sheet is opened under the action of negative pressure, so that the water in the sewage pipe is pumped into the pressure pipe, and the sewage is circulated and treated in this way;

[0020] S5. When the eccentric wheel rotates, one end of the lever is pushed upward, and the other end of the lever presses down the swing plate through the connecting rod, thereby driving the cone head to contact the water surface, thereby processing the foam on the water surface to prevent the foam from accumulating and overflowing.

[0021] The beneficial effects of the present invention are:

[0022] 1. The sludge treatment equipment disclosed in the present invention is provided with a floating object removal mechanism installed on one side of the partition, so that during the use of the equipment, the floating objects or oil on the water surface on one side of the partition can be lifted upwards through the reciprocating rotation of the swing box and poured into the oil collecting tank for collection, so as to facilitate people to collect, reduce manual labor and improve the automation degree of the equipment;

[0023] 2. The sludge treatment equipment disclosed in the present invention has a sewage return mechanism installed between the mixing box and the water removal tank, so that the precipitated unclean water discharged during the sludge removal can be pushed into the mixing box through the movement of the piston, and then circulated for treatment, thereby reducing the discharge of sewage and improving the quality of the discharged water;

[0024] 3. The sludge treatment equipment disclosed in the present invention is provided with a swinging plate installed in a mixing box, so that during the process of treating the medium, the swinging plate can swing, thereby driving the cone head to contact the water surface, thereby treating the foam on the water surface and preventing the foam from accumulating and overflowing;

[0025] 4. The sludge treatment equipment disclosed in the present invention can filter the discharged water again by installing a filter in the dewatering tank, thereby improving the quality of the discharged water and facilitating the direct use of the discharged water;

[0026] 5. The sludge treatment equipment disclosed in the present invention has a lifting cylinder installed in a mixing box. A stirring blade capable of stirring is installed in the lifting cylinder. The stirring blade stirs the medium to improve the mixing effect of the medium and prevent sedimentation from occurring in the lifting cylinder.

The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

10. The method for using the sludge treatment equipment according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, the muddy water mixed with the flocculant is injected into the mixing box (1) through the water inlet pipe (7), then enters the lifting cylinder (9) through the bottom of the partition (8), and then overflows from the lifting cylinder (9) to the other side of the lifting cylinder (9), and the sewage pump (5) is started. The sewage pump (5) conveys the muddy water to the water tank (3), and then enters the extrusion cylinder (28) after being guided by the funnel (27). At the same time, the motor (36) is started, and the motor (36) drives the driving shaft (29) and the extrusion blade (30) to rotate. The extrusion blade (30) pushes the mud in the water to one end of the pressure plate (31). As the pressure of the mud increases, the pressure plate (31) is pushed open, thereby separating the mud and water; S2, when the water flows through the water inlet pipe (7), the impact force of the water flows impacts the driving blade (15), the driving blade (15) rotates to drive the mounting shaft (14) to rotate, the mounting shaft (14) drives the cam (16) to rotate, the cam (16) pushes the first slide bar (19) to move, the first slide bar (19) pulls the swing box (22) to rotate through the support rod (23), when the swing box (22) rotates upward, the floating objects or oil on the water surface of one side of the partition (8) are lifted upward, after the swing box (22) continues to rotate, the floating objects in the swing box (22) are poured into the oil collecting box (20) for collection, so that people can collect them conveniently, when the protruding position of the cam (16) is away from the first slide bar (19), the swing box (22) is reset, and then the floating objects are collected reciprocatingly; S3. While the mounting shaft (14) is rotating, the rotating shaft (10) is also driven to rotate by the pulley (17), and the rotating shaft (10) drives the stirring blade (11) to rotate. The stirring blade (11) stirs the medium, thereby improving the mixing effect of the medium and preventing precipitation from occurring in the lifting cylinder (9); S4.
