Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a sedimentation device for industrial sewage treatment. Background Art

[0002] Industrial wastewater treatment sedimentation units are solid-liquid separation devices used in industrial wastewater, domestic sewage, or other water treatment systems to remove suspended solids, colloids, and partially soluble pollutants from water through gravity sedimentation. Their core goal is to reduce water turbidity, minimize subsequent treatment load, or recover useful substances.

[0003] Patent Publication No. CN208511951U discloses a sewage sedimentation device comprising a sedimentation tank and a water collection tank connected to the sedimentation tank. A water guide is located in the middle of the sedimentation tank, with a grid plate at its lower end. The upper end of the water collection tank is connected to a scum removal tank. A mud hopper is located at the lower end of the sedimentation tank, with the ends of the grid plate fixedly connected to the side walls of the water guide and the mud hopper, respectively. A water pipe for conveying water to be precipitated into the sedimentation tank extends from the side wall of the water guide and bends into the water guide. A mud discharge pipe is located at the bottom of the mud hopper, which is connected to a mud drying tank. This sewage sedimentation device can precipitate sewage and discharge scum, thereby reducing the environmental impact of sewage.

[0004] The above device needs to add flocculants during the sedimentation process, which easily leads to insufficient contact between the flocculants and sewage, thereby affecting the flocculation effect of the sewage. Therefore, a sedimentation device for industrial sewage treatment is proposed to solve the above problems. Summary of the Invention

The scraper 703 is hinged at the bottom of the Y-shaped frame 702, and the stopper 704 is fixedly connected to the bottom of the Y-shaped frame 702. The discharging mechanism 7 also includes: a cam 705, a discharging pipe 706, a rocker arm 707, and a push plate 708. The cam 705 is fixedly connected to both ends of the non-self-locking threaded rod 701, and the discharging pipe 706 is fixed.

At the same time, the scraper 703 participates in the discharge in both directions, which effectively saves power consumption compared to unidirectional motion. The continuous thrust of the reciprocating push plate 708 is more suitable for processing sticky or easily hardened sediments, and the symmetrically arranged discharge ports can also effectively avoid blockage caused by pressure concentration at the discharge ports. In order to improve the operation stability and efficiency of the lifting device, the lubrication mechanism 8 includes: an oil box 801, a fixed block 802, a push rod 803, a pressure cover 804, a return spring 805, and a limit block 806. The oil box 801 is fixedly connected to the top of the connecting seat 4, the fixed block 802 is fixedly connected to the outer wall of the pool body 1, the push rod 803 is slidably connected to the inner wall of the fixed block 802, the pressure cover 804 is fixedly connected to the top of the push rod 803, the limit block 806 is fixedly connected to the outer wall of the push rod 803, and the return spring 805 is fixedly connected to the top of the limit block 806.

[0018] Working principle: After sedimentation is completed, the treated sewage is pumped out, the electric slide 5 is started to drive the Y-frame 702 to move back and forth, the reciprocating movement of the Y-frame 702 drives the scraper 703 to move back and forth, the left scraper 703 moves forward and is blocked by the block 704, the scraper 703 pushes the sediment to the left front discharge port, when moving in the reverse direction, the right scraper 703 moves in the reverse direction and is blocked by the block 704 to push the sediment to the right back discharge port, in this way, the force strength of the scraper 703 can be effectively reduced and the service life can be improved, at the same time, the scraper 703 participates in the discharging both in the round trip, which can effectively save power consumption compared with the unidirectional movement. The Y-shaped frame 702 can also drive the non-self-locking threaded rod 701 to rotate. The rotation of the non-self-locking threaded rod 701 drives the cam 705 to rotate. The rotation of the cam 705 drives one end of the rocker arm 707 to move in a circular motion along with the cam 705. The other end of the rocker arm 707 drives the pusher plate 708 to move toward the outlet of the discharge pipe 706. As the cam 705 rotates, the pusher plate 708 reciprocates to discharge the sediment scraped by the scraper 703 through the discharge pipe 706. The continuous thrust of the reciprocating pusher plate 708 is more suitable for processing viscous or easily hardened sediments. The symmetrically arranged discharge ports can also effectively prevent blockage caused by concentrated pressure at the discharge port. This improves the operating stability and efficiency of the device.

[0019] When the cam 705 rotates, the raised part of the cam 705 contacts the push rod 803, and the cam 705 continues to rotate. The cam 705 pushes the push rod 803 to move upward, and the push rod 803 moves upward to drive the limit block 806 to move. The limit block 806 moves to drive the pressure cover 804 to move upward and compress the return spring 805. The pressure cover 804 moves upward. The lubricating oil in the oil box 801 flows through the bottom hole to the surface of the electric slide 5 for lubrication, ensuring the smooth operation of the electric slide 5 and improving its reliability. When the electric slide 5 needs to discharge material during operation, the electric The machine 807 starts, driving the screw 810 to rotate. The screw 810 rotates to drive the partition 809 to move upward along the guide rod 808 in the opposite direction to open the discharge port to discharge the material. At the same time, the moving electric slide rail 5 pushes the outflowing lubricating oil to the internal groove of the connecting seat 4, and guides the lubricating oil into the screw 810 through the oil pipe to form an oil film on the contact surface, converting solid friction into fluid friction, significantly reducing the friction coefficient, and isolating moisture, oxygen and corrosive chemicals in the air to prevent rust or chemical corrosion, thereby improving the service life of the device.
