Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an anaerobic tank for sewage treatment. Background Art

[0002] The anaerobic tank is a sewage treatment equipment that treats organic wastewater. It is a kind of equipment that uses anaerobic microorganisms to degrade organic matter in an oxygen-free environment and treats organic wastewater into recyclable water resources. In the anaerobic tank, organic matter is decomposed by microorganisms into methane, carbon dioxide and other substances, and a large amount of microbial sludge is produced. This sludge can be further processed to achieve the purpose of recycling water resources.

[0003] The Chinese patent with the authorization announcement number "CN220502812U" and the name "A Sewage Treatment Anaerobic Tank" includes an anaerobic tank body, with adjustment components at both opposite ends of the anaerobic tank body, and a stirring component between two groups of the adjustment components; each group of the adjustment components includes a fixed frame fixedly connected to the anaerobic tank body, the fixed frame is an L-shaped structure and a first mounting block is fixedly provided on the upper end thereof, a threaded rod is rotatably provided between two opposite inner walls of the first mounting block, a moving block is threadedly connected to the threaded rod, and a first motor for driving the threaded rod to rotate is fixedly installed on the fixed frame; the stirring component is movably arranged between two opposite moving blocks. The utility model solves the problem that the stirring device can only move within a fixed range and the stirring area is limited.

[0004] However, although the device expands the stirring range, the movement of the device in the length direction and the width direction of the anaerobic tank is independent of each other, so that the movement in the two directions needs to be manually controlled to coordinate the stirring of the anaerobic tank, resulting in low overall efficiency. In addition, frequent starting and stopping of the motor can easily lead to motor failure, thereby reducing its service life. Utility Model Content

[0025] See also Figure 1-4 , a sewage treatment anaerobic tank, comprising a frame 1 placed on the four sides of the anaerobic tank, the frame 1 is provided with an automatic start-stop mechanism, the automatic start-stop mechanism comprises a reduction assembly 2 and a transmission assembly 4; the reduction assembly 2 comprises a first motor 21 fixedly connected to the frame 1, the output shaft of the first motor 21 is respectively fixedly connected with a driving rod 22 and a power disk 27 rotatably connected, the driving rod 22 drives the power disk 27 to rotate intermittently through a connecting member 3; the transmission assembly 4 comprises a horizontal rod 41 slidably connected to the frame 1, the horizontal rod 41 is fixedly connected with a moving rod 42, the power disk 27 drives the horizontal rod 41 to move through the moving rod 42; a reciprocating mechanism 5 is also provided between the frame 1 and the horizontal rod 41, the reciprocating mechanism 5 is connected with a stirring mechanism 6. The first motor 21 is a forward and reverse motor.

[0026] The first motor 21 drives the driving rod 22 to rotate, and the driving rod 22 drives the power disk 27 to rotate intermittently through the connecting piece 3, so that the rotation speed of the power disk 27 is lower than that of the first motor 21 while the power disk 27 rotates intermittently, thereby reserving time for the stirring mechanism 6 to treat the sewage. The rotation of the power disk 27 drives the moving rod 42 to move, and the movement of the moving rod 42 drives the horizontal rod 41 to slide along the frame 1. After the horizontal rod 41 moves, the reciprocating mechanism 5 drives the stirring mechanism 6 to move from one side of the anaerobic tank to the other side to stir the sewage. The utility model can automatically complete the stirring work of the anaerobic tank without manual control, improve the sewage treatment efficiency, and the motor does not need to be frequently started and stopped, which prolongs the service life of the motor.

[0027] Further, the connecting member 3 includes a rotating disk 31 rotatably connected to the frame 1, a plurality of first slots 32 are circumferentially provided on the rotating disk 31, a first clip 23 matched with the first slot 32 is fixedly provided on the side of the driving rod 22 close to the power disk 27, a disc 24 is fixedly provided on the side of the power disk 27 close to the driving rod 22, the disc 24 is rotatably connected to the output shaft of the first motor 21, a plurality of second clips 25 matched with the first slot 32 are circumferentially fixedly provided on the disc 24, and the rotating disk 31 drives the power disk 27 to rotate through the engagement of the first slot 32 with the second clip 25.

[0028] The rotation of the driving rod 22 drives the first clamping rod 23 to rotate synchronously. The first clamping rod 23 rotates one circle to engage with the first clamping groove 32 once, and drives the rotating disk 31 to rotate. The rotation of the rotating disk 31 drives the disc 24 to rotate through the cooperation of the first clamping groove 32 and the second clamping rod 25. The rotation of the disc 24 drives the power disc 27 to rotate synchronously. The rotating disk 31 can realize the deceleration of the first motor 21 and the intermittent rotation of the power disc 27.

[0029] Furthermore, a plurality of third clamping rods 26 are fixedly provided on the power disk 27, and each of the third clamping rods 26 is arranged in a ring shape. A plurality of fourth clamping rods 43 are arranged in the length direction of the movable rod 42. The power disk 27 drives the third clamping rods 26 to rotate, and the rotation of the third clamping rods 26 drives the movable rod 42 to move through the fourth clamping rods 43.

[0030] The power disk 27 rotates to drive the third clamping rod 26 to rotate, and the third clamping rod 26 rotates to abut against the fourth clamping rod 43 and drives the fourth clamping rod 43 to move.

The second motor 51 is a forward and reverse motor.

[0032] The second motor 51 drives the screw rod 52 to rotate. Since the translation block 53 is constrained by the slide bar 54, the translation block 53 moves along the axial direction of the screw rod 52, thereby driving the stirring mechanism 6 to reciprocate in the length direction of the anaerobic tank.

[0033] Furthermore, the end of the screw rod 52 is rotatably connected to a slider 55, the end of the slide bar 54 is fixedly connected to the slider 55, and the slider 55 is slidably connected to the frame 1. The setting of the slider 55 makes the screw rod 52 and the slide bar 54 more stable when moving.

The first clamping rod 23 rotates one circle and engages with the first clamping groove 32 once, and drives the rotating disk 31 to rotate. The rotating disk 31 rotates and drives the disc 24 to rotate through the cooperation of the first clamping groove 32 and the second clamping rod 25. The rotation of the disc 24 drives the power disc 27 to rotate synchronously. The rotation of the power disc 27 drives the third clamping rod 26 to rotate. The third clamping rod 26 rotates to abut against the fourth clamping rod 43 and drives the fourth clamping rod 43 to move. The movement of the fourth clamping rod 43 drives the moving rod 42 and the horizontal rod 41 to move along the frame 1, so that the stirring mechanism 6 moves in the width direction of the ozone tank; the second motor 51 drives the screw rod 52 to rotate. Since the translation block 53 is constrained by the sliding rod 54, the translation block 53 moves along the axial direction of the screw rod 52, and then the translation block 53 drives the stirring mechanism 6 to reciprocate in the length direction of the anaerobic tank, thereby realizing automatic stirring of the anaerobic tank.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
