[0019] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0020] A sludge cleaning device for sewage treatment provided by the present invention includes a steady flow transmission shaft 1, a bearing seat 2, a sludge cleaning mechanism 3, a cross beam 4 and a driving component 5. The lower end of the steady flow transmission shaft 1 is connected to the bearing seat 2 embedded in the bottom of the sewage tank. Two mirror-image arranged sludge cleaning mechanisms 3 are fixedly installed on the steady flow transmission shaft 1; the cross beam 4 is fixedly installed in the middle of the sewage tank. The upper end of the steady flow transmission shaft 1 rotates through the cross beam 4 and is fixed to the output end of the driving component 5 fixedly installed on the cross beam 4.

[0021] The sludge cleaning mechanism 3 includes an integrated cross plate 31, a sludge collecting plate 32, a sludge suction head 33, a sludge suction pipe 34, a sludge suction pump 35, a sludge collecting box 36 and a reinforcing frame 37. One end of the integrated cross plate 31 is fixedly connected to the steady flow transmission shaft 1; the sludge collecting plate 32 and the sludge suction head 33 are fixedly installed below the integrated cross plate 31. The sludge suction head 33 is communicated with the sludge suction pipe 34, and the sludge suction pipe 34 is communicated with the sludge collecting box 36 through the sludge suction pump 35; the sludge suction pump 35 is fixedly installed at one lower end of the sludge collecting box 36; the reinforcing frame 37 is fixedly connected to the integrated cross plate 31, the steady flow transmission shaft 1 and the sludge collecting box 36 respectively, and the sludge collecting box 36 is fixedly installed on the steady flow transmission shaft 1. The driving component 5 drives the sludge cleaning mechanism 3 to rotate through the steady flow transmission shaft 1, so as to achieve a comprehensive and thorough cleaning of the bottom of the tank, and can pump the sludge out without the need for staff to go deep into the bottom of the tank for sludge cleaning treatment.

[0022] Embodiment 1:

[0023] Specifically, the steady-flow transmission shaft 1 is composed of a steady-flow cylinder, a transmission shaft, and a flange. The steady-flow cylinder is fixedly connected to the output end of the driving component 5, the sludge collection tank 36, and the reinforcement frame 37 respectively; the transmission shaft is fixedly connected to the integrated transverse plate 31 through the flange, and the transmission shaft is installed with the bearing seat 2, and the bearing seat 2 is an underwater bearing seat structure.

[0024] Specifically, the sludge collection plate 32 fixedly installed below the integrated transverse plate 31 is a bent plate composed of a plurality of V-shaped bending parts. The unique design endows the sludge collection plate 32 with excellent sediment aggregation ability. Each V-shaped bending part is like a miniature vortex generator. When the integrated transverse plate 31 drives the sludge collection plate 32 to rotate in the sewage tank, these V-shaped bending parts will guide the water flow to form a plurality of small vortex areas. These vortices not only help to aggregate the sediment and impurities scattered at the bottom of the tank towards the inner side of the sludge collection plate 32, but also increase the contact area between the sediment and the sludge collection plate, improving the aggregation efficiency. The sludge suction head 33 is cleverly arranged inside the V-shaped bending part of the sludge collection plate 32. This layout ensures that the sludge suction head 33 can directly align with and cover the sediment area aggregated by the vortices, thus maximizing the sludge suction efficiency. The sludge suction head 33 sucks the sediment and impurities aggregated inside the sludge collection plate 32 quickly through the sludge suction pump 35 and transports them into the sludge collection tank 36 through the sludge suction pipe 34.

[0025] Specifically, the sludge suction pipe 34 is an "L"-shaped elbow structure, which not only meets the requirements of the spatial layout, but also optimizes the hydrodynamic performance. The lower end of the sludge suction pipe 34 is connected to a plurality of the sludge suction heads 33, ensuring that each sludge suction head 33 can smoothly introduce the medium into the sludge suction pipe 34 when sucking sediment. This design of multiple sludge suction heads 33 docking improves the suction efficiency, enabling the sludge cleaning device to cover a wider area in a short time and complete the cleaning work of a large amount of sediment. The upper end of the sludge suction pipe 34 is cleverly connected to the input end pipe orifice of the sludge suction pump 35. When the sludge suction pump 35 is started, its strong suction force is transmitted to the sludge suction head 33 through the sludge suction pipe 34, sucking the sediment and impurities aggregated inside the sludge collection plate 32 quickly and transporting them upward. The sludge suction pump 35 discharges the preliminarily treated sediment and impurities into the rectangular sludge collection tank 36 through its output end pipe orifice. The sludge collection tank 36, as a temporary storage container, can accommodate a large amount of sediment and impurities, providing convenience for subsequent cleaning and transportation work.

[0026] Specifically, the reinforcement frame 37 is a reinforcement support frame composed of a number of diagonal braces and support rods. The diagonal braces, as the main load-bearing members of the reinforcement frame 37, are connected between the support rods at an inclined angle. This design not only enhances the overall stiffness of the reinforcement frame but also effectively disperses various forces and vibrations generated during the operation of the device. The support rods are the framework of the reinforcement frame 37. They are perpendicular to the ground or arranged at a specific angle, providing a solid support foundation for the entire device. The support rods and diagonal braces cooperate with each other to jointly bear the weight of the device and the dynamic load during operation.

[0027] Embodiment 2:

[0028] When it is necessary to clean the sediment at the bottom of the sewage tank, first start the driving component 5. After the driving component 5 is started, the steady-flow transmission shaft 1 drives the integrated cross plate 31 and the sludge collecting plate 32 below to rotate. The unique V-shaped bending part design of the sludge collecting plate 32 guides the water flow to form multiple eddy regions during the rotation process, effectively gathering the sediment and impurities at the bottom of the tank towards the inner side of the sludge collecting plate. The sludge suction head 33 is arranged inside the V-shaped bending part of the sludge collecting plate 32, directly aiming at the sediment area where the eddies gather. When the sludge suction pump 35 is started, the suction force generated by it is transmitted to the sludge suction head 33 through the sludge suction pipe 34, quickly sucking in the gathered sediment and impurities. The sludge suction pipe 34 transports the sucked sediment and impurities into the sludge collecting box 36. The sludge collecting box 36, as a temporary storage container, has a rectangular design that facilitates subsequent cleaning and transportation work. The output end pipe orifice of the sludge suction pump 35 is directly connected to the sludge collecting box 36 to ensure that the sediment can be smoothly and efficiently discharged into the box. The reinforcement frame 37 is composed of diagonal braces and support rods, enhancing the structural stiffness and stability of the entire sludge cleaning device. The diagonal braces are connected to the support rods at an inclined angle, effectively dispersing the forces and vibrations generated during the operation of the device and ensuring the stable operation of the device under high-speed rotation. The reinforcement frame 37 is fixedly connected to the integrated cross plate 31, the steady-flow transmission shaft 1, and the sludge collecting box 36 respectively, forming a stable overall structure and improving the reliability and safety of the device.
