[0014] A treatment method of a sewage filtration treatment device for construction engineering, using the above-mentioned sewage filtration treatment device for construction engineering, comprises the following steps: Step 1: Sewage enters the treatment box through the water inlet. The sewage contacts the L-shaped plate during flow. The flowing sewage exerts a continuous thrust on the L-shaped plate, causing the L-shaped plate to rotate away from the rectangular plate. Step 2: The L-shaped plate rotates to drive the rotating plate to rotate in a direction away from the rectangular plate. The rotating plate stretches the No. 1 torsion spring during the rotation.

Step 3: The L-shaped plate exerts resistance on the flowing sewage, and the flow speed of the sewage is slowed down by the resistance. After the sewage is separated from the L-shaped plate, the sewage continues to flow and contacts the filter plate. The foreign matter in the sewage is intercepted by the filter plate and stops moving downward; Step 4: The filtered sewage flows downward and contacts the inner wall of the sedimentation tank. In the sedimentation tank, the particles in the sewage settle downward, and the precipitated sewage is discharged from the treatment tank through the outlet.

[0015] The present invention provides a sewage filtering and treating device for construction engineering, which has the following beneficial effects: (1) The sewage filtering and treatment device used in the construction project has an L-shaped plate which exerts resistance on the flowing sewage. The flow rate of the sewage is slowed down by the resistance. The L-shaped plate is set to slow down the flow rate of the sewage, and foreign matter in the sewage is prevented from damaging the filter plate when the fast-flowing sewage passes through the filter plate, thereby extending the service life of the filter plate. At the same time, the L-shaped plate contacts the floating objects on the water surface during movement, and the floating objects are concentrated on one side through the L-shaped plate, which is convenient for centralized treatment of the floating objects. The convex rod is used to exert a stable pressure on the filter plate to prevent the filter plate from loosening under the scouring of sewage.

[0016] (2) In the sewage filtration and treatment device used in the construction project, the scraper guides the foreign matter to move toward the storage box, and the foreign matter is collected by the storage box during the movement. By collecting the foreign matter on the top of the filter plate, the foreign matter is prevented from accumulating on the top of the filter plate and affecting the smoothness of sewage flow, thereby ensuring the stability of sewage treatment. At the same time, the bottom of the limit plate contacts the top of the card plate during rotation. Through standardized operation, the operator can quickly adjust the position of the limit plate and flexibly choose whether to enable the storage box to collect foreign matter, thereby enhancing the convenience of operation.

[0017] (3) The sewage filtration and treatment device used in this construction project accelerates the sedimentation reaction after the coagulant contacts the sewage, thereby improving the sedimentation efficiency of the sewage. By moving the telescopic plate, a quantitative amount of coagulant is automatically discharged into the sewage to accelerate the efficiency of sewage sedimentation, thereby improving the overall treatment efficiency and ensuring the realization of environmental protection goals. At the same time, the knocking plate collides with the elastic plate to generate vibration, and the knocking plate collides with multiple elastic plates to generate intermittent vibration, which effectively ensures the smoothness of the movement of the telescopic plate and ensures that the telescopic plate can smoothly drive the coagulant to be discharged.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The rectangular plate 10 contacts the side of the L-shaped plate 9 away from the driving motor 4. A convex rod 11 slides through the bottom of the mounting frame 6. A spring 12 is arranged between the convex rod 11 and the mounting frame 6. The convex rod 11 applies a stable pressure to the filter plate 3 to prevent the filter plate 3 from loosening under the flushing of sewage.

[0023] A torsion spring No. 1 is arranged between the rotating plate 8 and the rotating shaft 7. A slide groove is provided on the top of the filter plate 3. The bottom of the convex rod 11 contacts the slide groove. The floating objects are concentrated on one side through the L-shaped plate 9, which is convenient for centralized processing of the floating objects.

[0024] A treatment method of a sewage filtration treatment device for construction engineering, using the above-mentioned sewage filtration treatment device for construction engineering, comprises the following steps: Step 1: Sewage enters the treatment box 1 through the water inlet, and the sewage contacts the L-shaped plate 9 during the flow. The flowing sewage exerts a continuous thrust on the L-shaped plate 9, causing the L-shaped plate 9 to rotate in a direction away from the rectangular plate 10; Step 2: The L-shaped plate 9 rotates to drive the rotating plate 8 to rotate in a direction away from the rectangular plate 10. The rotating plate 8 stretches the first torsion spring during the rotation. The first torsion spring is deformed by the stretching and exerts a reaction force on the rotating plate 8. Step 3: The L-shaped plate 9 exerts resistance on the flowing sewage, and the flow speed of the sewage is slowed down by the resistance. After the sewage is separated from the L-shaped plate 9, the sewage continues to flow and contacts the filter plate 3. The foreign matter in the sewage is intercepted by the filter plate 3 and stops moving downward; Step 4: The filtered sewage flows downward and contacts the inner wall of the sedimentation tank 2. In the sedimentation tank 2, the particles in the sewage settle downward, and the precipitated sewage is discharged from the treatment tank 1 through the outlet.

[0025] When the present embodiment is working, sewage enters the treatment box 1 through the water inlet, and the sewage contacts the L-shaped plate 9 during the flow. The flowing sewage applies a continuous thrust to the L-shaped plate 9, causing the L-shaped plate 9 to rotate in a direction away from the rectangular plate 10. The L-shaped plate 9 rotates and separates from the rectangular plate 10. At the same time, the rotation of the L-shaped plate 9 drives the rotating plate 8 to rotate in a direction away from the rectangular plate 10. The rotating plate 8 stretches the No. 1 torsion spring during the rotation. The No. 1 torsion spring is deformed by the stretching and applies a reaction force to the rotating plate 8, causing the L-shaped plate 9 to apply resistance to the flowing sewage, and the flow speed of the sewage is affected. The influence of the resistance is reduced. After the sewage is separated from the L-shaped plate 9, the sewage continues to flow and contacts the filter plate 3. The foreign matter in the sewage is intercepted by the filter plate 3 and stops moving downward, while the filtered sewage flows downward and contacts the inner wall of the sedimentation tank 2. In the sedimentation tank 2, the particles in the sewage settle downward, and the precipitated sewage is discharged from the treatment tank 1 through the outlet. The flow rate of the sewage is reduced by setting the L-shaped plate 9 to prevent the foreign matter in the sewage from damaging the filter plate 3 when the fast-flowing sewage passes through the filter plate 3, thereby extending the service life of the filter plate 3. The filter plate 3 is submerged during continuous discharge, and the buoyancy exerted by the sewage drives the floating objects to move upward and separate from the filter plate 3. When the sewage rises to a specified height, the discharge is stopped, and the drive motor 4 is started. The output end of the drive motor 4 drives the screw rod 5 to rotate clockwise, and the screw rod 5 rotates clockwise to drive the carrying frame 6 to move in the direction of the drive motor 4. The movement of the carrying frame 6 drives the rotating shaft 7 and the rectangular plate 10 to move in the direction of the drive motor 4. The movement of the rotating shaft 7 drives the rotating plate 8 to move in the direction of the drive motor 4. The movement of the rotating plate 8 drives the L-shaped plate 9 to move in the direction of the drive motor 4. The plate 9 contacts the floating objects on the water surface during movement, so that the L-shaped plate 9 moves and drives the floating objects to move toward the driving motor 4. At the same time, the carrying frame 6 moves and drives the convex rod 11 to move toward the driving motor 4. The deformed spring 12 applies a continuous reaction force to the convex rod 11 to ensure that the convex rod 11 is always in close contact with the slide groove during movement. The floating objects are concentrated on one side through the L-shaped plate 9, which is convenient for centralized processing of the floating objects. The convex rod 11 applies a stable pressure to the filter plate 3 to prevent the filter plate 3 from loosening under the flushing of sewage.

A coagulant is arranged inside the liquid storage box 141. A circular hole is opened inside the liquid storage box 141, and a rectangular groove is opened inside the telescopic plate 142. The liquid storage box 141 is connected with the interior of the rectangular groove through the circular hole. The contact plate 144 contacts the circumferential surface of the gripping rod 138.

After the limit plate 139 moves to the specified position, the control handle 138 is rotated toward the card plate 137.

At the same time, the movement of the telescopic plate 142 drives the coagulant inside the rectangular groove to move toward the driving motor 4. The rectangular groove is separated from the inner wall of the liquid storage box 141 during movement, so that the coagulant inside the rectangular groove flows downward and contacts the sewage at the water inlet. After the coagulant contacts the sewage, the precipitation reaction is accelerated, thereby improving the sedimentation efficiency of the sewage.

When contacting the first elastic piece 147, the arc surface 2 of the knocking piece 146 is affected by the resistance and rotates in the direction of the No. 2 spring 143. The knocking piece 146 stretches the No. 3 torsion spring during the rotation, and the No. 3 torsion spring is deformed due to the stretching. The knocking piece 146 continues to move and separates from the first elastic piece 147, so that the deformed No. 3 torsion spring recovers and drives the knocking piece 146 to quickly reset. The knocking piece 146 collides with the second elastic piece 147 to generate vibration during the reset, and then repeats the above movement to collide with the third elastic piece 147 to generate vibration. The intermittent vibration is generated by the collision of the knocking piece 146 with multiple elastic pieces 147, which effectively ensures the smoothness of the movement of the telescopic plate 142 and ensures that the telescopic plate 142 can smoothly drive the coagulant to be discharged.
