Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a floating object collecting structure. Background Art

[0002] When using a sewage sedimentation tank for sewage treatment, adding chemicals is a crucial step. These chemicals usually include various chemical or biological agents, which can quickly react with impurities in the sewage after contacting the sewage to form floating objects and flocculants. As floating objects and flocculants accumulate, their density gradually increases, and floating objects floating on the water surface have to be fished out and processed.

[0003] At present, when cleaning floating objects on the water surface of a sewage sedimentation tank, they are mostly scooped up manually with the help of tools; for example, a utility model patent with authorization announcement number CN219174271U discloses a floating object scooping device for sewage treatment, which comprises a rod body, a scooping net is arranged on one side of the rod body, an anti-dropping device is arranged on one side of the rod body, a connecting device is arranged between the rod body and the scooping net, and the anti-dropping device comprises a cylinder, an inner wall of the cylinder is slidably connected to the surface of the rod body, a rectangular rod is fixedly connected to one side of the cylinder, a baffle is fixedly connected to one end of the rectangular rod, and a round rod is fixedly connected to the end of the rectangular rod away from the baffle. By setting up an anti-drop device, under the action of the cylinder, the round rod can drive the rectangular rod to move left and right, and the rectangular rod can drive the baffle to move left and right, so that the baffle can be moved to a position above the scoop net to intercept the debris inside the scoop net, thereby reducing the shaking of the scoop net during the retrieval process, causing the internal debris to tip over and fall out of the scoop net, thereby improving the efficiency of personnel in cleaning and recovering floating objects.

[0004] Although the device improves the efficiency of personnel in cleaning and recovering floating objects, the device requires manual scooping when cleaning floating objects. This method is not only time-consuming and laborious in collecting floating objects, but also continuously operates on the side of the sewage pool, increasing the risk of workers falling into the water. In view of this, we propose a floating object collection structure. Utility Model Content

[0017] Through the collection part set up: the second motor rotates to drive the gear to rotate, the gear moves along the rack and drives the fixed frames on both sides to move from the two sides of the sewage sedimentation tank to the middle. With the movement of the fixed frame, the fixed frame pushes the floating objects on the surface of the sewage to gather to the middle. When the floating objects are gathered together, the augers on both sides rotate synchronously. With the rotation of the augers, the floating objects can move to the discharge trough with the augers, and then be discharged to the outside through the discharge trough conveniently. This design does not require manual scooping when cleaning floating objects, thereby improving the safety of the operation and improving the operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Furthermore, a notch 271 is provided at the bottom of the second fixing block 27 at the front side, and the rack 15 passes through the notch 271. The design of the notch 271 facilitates the horizontal movement of the second fixing block 27 and prevents the rack 15 from affecting the second fixing block 27.

[0032] Furthermore, the cross-section of the fixing frame 21 is U-shaped, and the fixing frame 21 is a stainless steel sheet. The U-shaped design is conducive to collecting floating objects on the water surface, and the stainless steel material has the advantage of corrosion resistance, which ensures the service life of the fixing frame 21.

[0033] Furthermore, a sewage inlet 10 is installed at the top of the front end surface of the sewage sedimentation tank 1, and a plug is provided at the sewage inlet 10. The sewage inlet is convenient for sewage to enter the sewage sedimentation tank 1.

[0034] Further, the transmission assembly 25 includes two sprockets, the lower sprocket is coaxially keyed to the auger 22, and the upper sprocket is coaxially keyed to the output shaft of the first motor 24. The transmission assembly 25 is convenient for driving the auger 22 to rotate, and it is convenient for the auger 22 to transport floating objects on the water surface.

[0035] It is worth noting that the first motor 24 and the second motor 28 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0036] When in use, the user first turns on the power of the second motor 28, and the second motor 28 starts to work. The output shaft of the second motor 28 rotates to drive the gear 29 to rotate. Because the gear 29 is meshed with the rack 15, the gear 29 moves along the rack 15 and drives the top plate 20 and the fixing frame 21 to be horizontal. At this time, the fixing frames 21 on both sides move from both sides to the middle, and the fixing frames 21 simultaneously drive the floating objects on the water surface to move to the middle. When the floating objects gather in the middle, the user stops the power of the second motor 28 and turns on the power of the first motor 24. The first motor 24 starts to work. The output shaft of the first motor 24 rotates to drive the sprocket to rotate. Driven by the chain, the two sprockets rotate synchronously and drive the auger 22 to rotate. As the auger 22 rotates, the floating objects on the water surface move to the discharge slot 14 and are discharged.

[0039] Furthermore, the overall shape of the gate plate 32 is T-shaped, and the size of the gate plate 32 is adapted to the size of the discharge slot 14. This design is beneficial for the gate plate 32 to block the discharge slot 14 and also beneficial for the gate plate 32 to perform lifting and lowering movements.

[0040] Furthermore, the overall shape of the bracket 30 is U-shaped, and the bracket 30 is fixedly connected to the flange 11 by bolts. The U-shaped design facilitates the bracket 30 to stably support the electric cylinder 31, and the bolt fixing method ensures the installation reliability of the bracket 30.

[0041] When in use, the user first turns on the power of the electric cylinder 31, and the electric cylinder 31 starts to work. The piston rod of the electric cylinder 31 drives the gate plate 32 to move upward, and the gate plate 32 is separated from the discharge groove 14, and the discharge groove 14 is exposed.
