DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] The following further describes the present utility model in detail with reference to embodiments:

[0023] Embodiment 1

[0024] As Figures 1 - 4 shown, the present utility model provides a self-floating slag scraping structure, including a sewage treatment tank 1 and a central column 2. The bottom of the inner wall of the sewage treatment tank 1 is rotatably connected to the central column 2. A sludge suction pipe 3 is fixedly connected to the outer wall of the central column 2 near the bottom end. A slag scraping arm 6 is arranged on the outer wall of the central column 2 near the top end. A square floating block 11 for providing buoyancy support is arranged on the inner wall of the slag scraping arm 6. A slag scraping arm tie rod 7 is fixedly connected to the upper surface of the end of the slag scraping arm 6 away from the central column 2. After the device is designed to be lightweight, the self-weight of the equipment can be effectively reduced. The equipment can be reduced in weight by about 40% to 50%, greatly reducing the operation load of the equipment. At the same time, the completely symmetrical arrangement of the sludge suction and scraping pipes can ensure the levelness of the equipment and reduce the difficulty of installation and debugging.

[0025] On the basis of ensuring strength, the weight of the equipment is reduced. The installation position of the slag scraping arm 6 is clockwise offset by 90°. At the same time, by changing the slag scraping arm 6 into a truss self-floating type, the fixed base under the slag scraping arm 6 is simplified. The removal of the fixed truss under the slag scraping arm 6 can remove the fixed truss and the counterweight cement block at the other end, thereby realizing the lightweight of the whole equipment.

[0026] A first cross beam 8 is fixedly connected to the outer wall of the top end of the central column 2. A first sludge suction pipe tie rod 4 and a second sludge suction pipe tie rod 5 are respectively fixedly connected to the upper surface of the sludge suction pipe 3. The ends of the first sludge suction pipe tie rod 4 and the second sludge suction pipe tie rod 5 away from the sludge suction pipe 3 are both fixedly connected to the first cross beam 8. The end of the slag scraping arm tie rod 7 away from the slag scraping arm 6 is fixedly connected to a second cross beam 9. The first cross beam 8 is located above the second cross beam 9.

[0027] A position adjustment assembly 12 for adjusting its own height is arranged at the end of the slag scraping arm 6 close to the central column 2.

[0028] Embodiment 2

[0029] As Figures 1 - 4As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the number of the first sludge suction pipe tension members 4 and the second sludge suction pipe tension members 5 is two groups, and the two groups of the first sludge suction pipe tension members 4 and the second sludge suction pipe tension members 5 are symmetrically distributed on both sides of the central column 2. One side of the slag scraping arm 6 is fixedly connected with a slag scraping plate 10.

[0030] The number of the slag scraping arm tension members 7 is two, and the two slag scraping arm tension members 7 are symmetrically distributed on both sides of the slag scraping arm 6.

[0031] The material can be selected as anti-corrosion aluminum or 304L stainless steel. The water-facing surface is installed with thin-walled plates, and square floating blocks are filled in the middle to ensure that the slag scraping arm 6 floats on the water surface.

[0032] One slag scraping arm tension member 7 is installed on each of the left and right sides of the slag scraping arm 6 to prevent the slag scraping arm from swinging.

[0033] A sleeve bracket 13 is arranged on the outer wall of the central column 2. The position adjusting assembly 12 includes a mounting arc plate 14 movably sleeved on the outer wall of the sleeve bracket 13, and one end of the mounting arc plate 14 is fixedly connected with one end of the slag scraping arm 6 close to the sleeve bracket 13.

[0034] A mounting plate 15 is fixedly connected to the outer wall of the sleeve bracket 13. One end of the mounting arc plate 14 is detachably fixedly connected with the mounting plate 15 through a fastening bolt 17. An adaptation groove 16 for adapting to the fastening bolt 17 is opened on one side of the mounting plate 15, and the number of the mounting plates 15 is two groups. When it is necessary to adjust the installation height of the slag scraping arm 6 on the central column 2, the fastening bolt 17 can be removed, and then the mounting arc plate 14 is moved up and down on the surface of the sleeve bracket 13 to a suitable height, and then the fastening bolt 17 is reset.

[0035] Next, the working principle of the self-floating slag scraping structure will be specifically described.

[0036] As Figures 1 - 4 shown, when the slag scraping arm 6 scrapes the slag on the sewage surface, it is supported by the buoyancy provided by the square floating blocks 11 installed thereon. At the same time, with the traction effect of the slag scraping arm tension members 7 on it, the slag scraping arm 6 can stably float on the sewage surface and perform the slag scraping work on the sewage surface under the drive of the central column 2.

[0037] When it is necessary to adjust the installation height of the slag scraping arm 6 on the central column 2, the fastening bolt 17 can be removed, and then the mounting arc plate 14 is moved up and down on the surface of the sleeve bracket 13 to a suitable height, and then the fastening bolt 17 is reset, and the height adjustment work of the slag scraping arm 6 can be completed.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "including", "comprising" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or still includes elements inherent to such a process, method, article or device. Without more limitations, elements defined by the statement "including one..." do not exclude the existence of additional identical elements in the process, method, article or device including the said elements. The above has generally described the present utility model in detail, but based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
