Technical Field

[0001] This utility model relates to the field of flow promoters, and more particularly to a submersible flow promoter for sewage discharge. Background Technology

[0002] Submersible jet mixers for sewage discharge are commonly used equipment in the field of sewage treatment. They typically work directly underwater and can be directly installed in various sewage treatment structures such as aeration tanks and anaerobic tanks. They work in conjunction with sewage treatment processes to affect the media within the tank and are suitable for tank environments in sewage treatment plants, industrial wastewater treatment stations, and other similar locations.

[0003] The existing equipment is directly and fixedly installed in a designated underwater location in aeration tanks, anaerobic tanks, equalization tanks, etc. After being powered on, the equipment runs continuously underwater. In conjunction with the sewage treatment process and other treatment equipment in the tank, it processes sewage, sludge and other media. It is suitable for sewage treatment plants, industrial park wastewater treatment stations and sewage treatment tank environments in various industrial production.

[0004] Existing submersible jet mixers for sewage discharge are prone to contact with debris in the sewage when operating in sewage treatment tanks. Common suspended or floating debris in sewage, such as ropes and plastic bags, easily become entangled on the high-speed rotating blades, affecting the normal operation of the equipment. Furthermore, there is no automatic cleaning function for the blades after they become entangled with debris, requiring workers to stop the machine and manually clean them underwater. This increases the complexity of the operation process and poses safety risks to workers due to the uncertainty of the underwater environment. Therefore, a new submersible jet mixer for sewage discharge is proposed to solve these problems. Utility Model Content

[0007] As a further description of the above technical solution: A rotating joint is rotatably fixedly connected to the outer wall of the support frame, a support foot is hinged to the outer wall of the rotating joint, a hinge joint is fixedly connected to the outer wall of the support frame, and a mounting plate is fixedly connected to the end of the hinge joint.

[0008] As a further description of the above technical solution: The transmission gear is rotatably connected to the outer wall of the mounting plate.

[0009] As a further description of the above technical solution: The baffle plate has a trumpet-shaped structure, and the larger diameter end of the baffle plate faces away from the mounting plate.

[0010] As a further description of the above technical solution: The inner wall of the blade assembly is in contact with the outer wall of the baffle plate.

[0011] As a further description of the above technical solution: The number of support feet is two, and the ends of the support feet are provided with anti-slip pads.

The sludge-blocking plate 6 has a trumpet-shaped structure, with the larger diameter end of the sludge-blocking plate 6 facing away from the mounting plate 5. The sludge-blocking plate 6 is used to guide sewage in and initially block debris.

[0020] Reference Figures 2-4A main rotating gear 12 is fixedly connected to the outer wall of the rotating shaft 16. The main rotating gear 12 transmits the power of the rotating shaft 16 to the gear ring 14 by meshing with the transmission gear 13. The outer wall of the main rotating gear 12 is meshed with the transmission gear 13, which is rotatably connected to the outer wall of the mounting plate 5. The transmission gear 13 plays the role of power transmission and steering, so that the gear ring 14 obtains a different rotation state from the rotating shaft 16. The outer wall of the transmission gear 13 is meshed with the gear ring 14, which drives the rotating ring 11 on the dirt-separating plate 6 to rotate through the connecting column 15. The inner wall of the mounting plate 5 is provided with a rotating groove 10, and the inner wall of the rotating groove 10 is rotatably connected to the rotating ring 11. The rotating ring 11 is used for mounting. The blade assembly 7 rotates, and the outer wall of the rotating ring 11 is fixedly connected to the blade assembly 7. The inner wall of the blade assembly 7 is in contact with the outer wall of the baffle plate 6. The blades of the blade assembly 7 are inclined and symmetrically arranged. The blade assembly 7 rotates with the rotating ring 11 to cut the filamentous debris passing through the sewage outlet 9 and prevent it from getting tangled in the paddle 8. The end of the rotating shaft 16 passes through the mounting plate 5 and is fixedly connected to the paddle 8. The rotation of the paddle 8 realizes the sewage pushing operation. The outer wall of the baffle plate 6 has sewage outlets 9 that cooperate with the blade assembly 7. Several sets of sewage outlets 9 are arranged in a ring according to the outer wall of the baffle plate 6. The sewage outlets 9 are used to allow sewage to enter and, at the same time, cooperate with the blade assembly 7 to cut the debris.

[0021] Reference Figures 1-2 The outer wall of the support frame 3 is rotatably fixedly connected to a rotating joint 17. The outer wall of the rotating joint 17 is hinged with two support feet 18, and the ends of the support feet 18 are provided with anti-slip pads.

The rotating ring 11 then drives the blade assembly 7 fixed on the outer wall to rotate synchronously. At the same time, the horn... The trumpet-shaped baffle plate 6, under the suction force generated by the rotation of the paddle blade 8, guides the sewage and filamentous debris in it to a number of sewage outlets 9 arranged in a ring on its outer wall. During the rotation, the blade assembly 7 cuts the filamentous debris passing through the sewage outlets 9 with its inclined and symmetrical blades close to the outer wall of the baffle plate 6, preventing it from wrapping around the paddle blade 8. The rotating joint 17 on the outer wall of the support frame 3 cooperates with the two support feet 18 with anti-slip pads at the ends to adjust the pitch angle of the equipment to adapt to the installation requirements of different pools. The mounting plate 5 provides the mounting base for components such as the transmission gear 13 and the rotating ring 11, ultimately achieving a comprehensive operation of stable equipment fixation, sewage propulsion, and prevention of filamentous debris entanglement.
