Technical Field

[0001] This invention belongs to the field of sludge removal technology, and particularly relates to a sludge removal device and method for anaerobic ponds used in sewage treatment. Background Technology

[0002] An anaerobic wastewater treatment tank is a biological treatment structure that utilizes anaerobic microorganisms to decompose organic pollutants in water under anaerobic conditions. It is mainly used to degrade macromolecular organic matter in wastewater, creating conditions for subsequent treatment. Sludge removal from an anaerobic wastewater treatment tank refers to the process of periodically removing excess or aged sludge accumulated at the bottom of the tank from the system to maintain the high efficiency of microbial activity and treatment stability within the reactor.

[0003] However, in actual use, traditional sludge removal equipment causes the accumulated sludge to squeeze and overlap each other, resulting in sludge compaction. This compaction reduces the suction efficiency during the pumping process. To solve this problem, there is an urgent need for a sludge removal device and method for anaerobic ponds in wastewater treatment. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the suction efficiency of traditional suction equipment is affected by sludge caking during suction, and to propose a sludge discharge device and sludge discharge method for anaerobic ponds in sewage treatment.

[0014] A method for sludge removal from an anaerobic tank in wastewater treatment specifically includes the following steps: The motor drives the suction pipe to rotate, which in turn drives the support rod to rotate. The support rod, through the support ring, drives the first gear to move on the inner wall of the first gear ring. This causes the first gear to drive the movable rod to rotate through the transmission rod. The movable rod, through the first and second bevel gears, drives the worm gear to rotate.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting up a stirring device, the suction pipe is driven to rotate by a motor, the suction pipe drives the support rod to rotate, and the support rod drives the first gear to move on the inner wall of the first gear ring through the support ring. Thus, the first gear drives the movable rod to rotate through the transmission rod, and the movable rod drives the worm to rotate through the first bevel gear and the second bevel gear. The worm drives the worm wheel to rotate, and the worm wheel drives the stirring blades to stir the sludge inside the sludge, so that the sludge is stirred up and the sludge on the sludge plate does not affect the suction efficiency.

[0016] 2. In this invention, by setting up a lifting device, the suction pipe drives the fixed block and the rotating rod to rotate. The rotating rod drives the second gear to move and rotate the inner wall of the second gear ring. In turn, the second gear drives the reciprocating screw to rotate in the screw seat through the rotating rod. Through transmission, the connecting block drives the connecting pipe to move up and down. As a result, the connecting rod drives the stirring blade to move up and down through the support box and the connecting box, thereby increasing the stirring mode and further improving the suction efficiency.

[0017] 3. In this invention, by setting up a protective device, the connecting block moves when the connecting pipe moves up and down, causing the connecting block to squeeze the protective cylinder. This causes the protective cylinder to squeeze the spring, forcing the spring to generate a rebound force. The rebound force of the spring causes the bottom of the protective cylinder to always be in close contact with the top of the connecting block, so that the protective cylinder and the support cylinder protect the reciprocating screw and prevent impurities from adhering to the surface of the reciprocating screw and affecting the transmission.

[0029] The specific implementation method is as follows: By setting up a lifting device 8, the suction pipe 3 drives the fixed block 806 to move, the fixed block 806 drives the rotating rod 808 to rotate, the rotating rod 808 drives the second gear 807 to move, and the first gear 706 meshes with and moves inside the second gear ring 809, so that the second gear ring 809 rotates while driving the second gear 807 to move, thereby causing the second gear 807 to drive the rotating rod 808 to rotate, the rotating rod 808 drives the reciprocating screw 805 to rotate, and the reciprocating screw 805 rotates in the screw seat 802, forcing the reciprocating screw 805 to drive the screw seat 802 to move up and down, the screw seat 802 drives the connecting block 801 to move up and down, the connecting block 801 drives the connecting pipe 6 to move up and down, so that the connecting rod drives the stirring blade 717 to move up and down through the support box 11 and the connecting box 705, thereby increasing the stirring mode and further improving the suction efficiency.

[0030] Please see Figures 8-9 The bottom of the fixing block 806 is connected to a protective device 9. The protective device 9 also includes a support cylinder 901 and a protective cylinder 905.

The spring 903 is sleeved on the outside of the fixing rod 902, and the two ends of the spring 903 are respectively connected to one side of the allowance groove 904 and one side of the inner wall of the protective groove 906.

[0032] The specific implementation method is as follows: By setting up the protective device 9, when the connecting block 801 is moved upward by the connecting pipe 6, the connecting block 801 squeezes the protective cylinder 905. When the protective cylinder 905 moves, it squeezes the spring 903, forcing the spring 903 to generate a rebound force. By setting up the fixing rod 902 to support the spring 903, the spring 903 is prevented from bending during compression, which would affect the rebound effect of the spring 903. When the connecting block 801 moves downward, the rebound force of the spring 903 drives the protective cylinder 905 to move downward, so that the bottom of the protective cylinder 905 is always in close contact with the top of the connecting block 801. This allows the protective cylinder 905 and the support cylinder 901 to protect the reciprocating screw 805, preventing impurities from adhering to the surface of the reciprocating screw 805 and affecting the transmission. By setting up the allowance groove 904 to install the spring 903, the spring 903 has sufficient space during compression, preventing the spring 903 from being over-compressed and damaged, thus affecting its use.

[0033] Working Principle: During sewage treatment, the output shaft of motor 4 drives the drive wheel 13 to rotate. The drive wheel 13 drives the rotating ring 14 to rotate via the transmission gear ring 12. The rotating ring 14 drives the suction pipe 3 to rotate. The suction pipe 3 drives the connecting pipe 6 to rotate. The connecting pipe 6 drives the branch pipe 10 to rotate via the support box 11. During the rotation of the suction pipe 3, the support rod 708 rotates. The support rod 708 drives the support ring 707 to move. The support ring 707 drives the first gear 706 to move to one side of the first gear ring 701, causing the first gear ring 701 to drive the first gear 706 to rotate. This causes the first gear 706 to drive the transmission rod 703 to rotate. The transmission rod 703 drives the movable rod 704 to rotate. The movable rod 704 drives the first bevel gear 712 to rotate. The first bevel gear 712 drives the second bevel gear 713 to rotate. The second bevel gear 713 drives the worm gear 714 to rotate. The worm gear 714 drives the worm wheel 715 to rotate. Wheel 715 drives sealing sleeve 716 to rotate, and sealing sleeve 716 drives agitator blade 717 to rotate, so that agitator blade 717 agitates the sludge on the slab for easy suction. When connecting pipe 6 and suction pipe 3 rotate, they drive fixing block 806 to rotate. Fixing block 806 drives second gear 807 to move inside the second gear ring 809, so that second gear 807 drives rotating rod 808 to rotate. Rotating rod 808 drives reciprocating screw 805 to rotate. Reciprocating screw 805 rotates in screw seat 802, so screw seat 802 drives connecting block 801 to move. Connecting block 801 drives connecting pipe 6 to move up and down, thereby increasing the agitation of agitator blade 717 and further improving suction efficiency. Finally, protective cylinder 905 slides in protective groove 906, so that protective cylinder 905 and support cylinder 901 protect reciprocating screw 805 and prevent impurities from adhering to the surface of reciprocating screw 805 and affecting transmission.
