Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a sewage treatment sludge dewatering machine, including a support frame 1, which supports the entire sewage treatment sludge dewatering machine. An organic body 2 is installed on the upper part of the support frame 1. It is a screw dewatering machine, in which fixed rings and moving rings are stacked on each other and a spiral shaft runs through them. Gravity concentration and the internal pressure formed by the back pressure plate 4 are used to dewater the sludge. The filtrate is discharged from the filter gap formed by the fixed rings and moving rings, and the sludge cake is discharged from the end of the dewatering section. This technology is prior art, so it will not be described in detail. A drive motor 3, which is a geared motor, is fixedly connected to the right side of the machine body 2. It provides power for the operation of the entire equipment. The output shaft of the drive motor 3 is fixedly connected to the outside of the back pressure plate 4. The back pressure plate 4 helps to fully dewater the sludge by forming internal pressure. At the same time, it serves as the mounting carrier for the cleaning component 5, providing an installation position for the cleaning component 5. The cleaning component 5 is installed on the outside of the back pressure plate 4. The cleaning component 5 includes a mounting base 51 fixedly installed on the right side of the back pressure plate 4 by bolts, which is used to fix the support rod 52.

[0034] Reference Figure 2 - Figure 4The inner wall of the mounting base 51 is provided with a support rod 52, which serves to support and position the mounting, providing an installation position for the connecting column 56 and the scraper 55. The support rod 52 is fixedly installed on the inner wall of the mounting base 51 by fastening screws 53. A slot 54 is opened on the upper left side of the support rod 52 for installing the connecting column 56. The connecting column 56 is inserted into the inner wall of the slot 54 to connect the scraper 55 and the support rod 52, allowing for quick disassembly. The scraper 55, which contacts the outer side of the machine body 2, is fixedly connected to the left side of the connecting column 56. 5. The scraper 55 contacts the outside of the machine body 2. The left rear side of the scraper 55 is set as an inclined surface. When the back pressure plate 4 drives the cleaning component 5 to rotate, the silicone scraper 55 fits better against the surface of the machine body 2 to scrape off the sludge and prevent the sludge from accumulating on the surface of the machine body 2, thereby reducing the cleaning burden on the workers. The connecting column 56 and the scraper 55 are fixed to the outside of the support rod 52 by the disassembly component 6. The cleaning component 5 is provided in multiple sets. The multiple sets of cleaning components 5 are arranged in a circumferential array on the outside of the back pressure plate 4, which improves the cleaning efficiency.

[0035] Reference Figure 4 - Figure 6 The disassembly assembly 6 includes a fixing cap 61 located on the upper part of the support rod 52, used to fix the position of the connecting column 56 and the scraper 55 on the support rod 52. The fixing cap 61 is fixedly connected to the connecting column 56 by screws. When disassembling the fixing cap 61, the connecting column 56 and the scraper 55 can be directly pulled out by fixing with screws. A movable part 62 is slidably connected to the inner wall of the fixing cap 61, used to drive the limiting part 66 to move. A through groove 63 is opened through the middle of the movable part 62, used to accommodate the fixing block 64 and the compression spring 65. The fixing block 64 is fixedly connected to the inner wall of the fixing cap 61 and slides on the inner wall of the through groove 63. The fixing block 64 limits the movable part 62 to prevent the movable part 62 from falling off the fixing cap 61, and at the same time provides an installation point for the compression spring 65.

[0036] Reference Figure 4 - Figure 6The fixed block 64 is elastically connected to the through groove 63 via a compression spring 65, allowing the movable part 62 to reset through elastic force. Because the back pressure plate 4 rotates slowly, the limiting member 66 is stably inserted into the limiting groove 67. A limiting member 66, which slides on the inner wall of the fixed cap 61, is fixedly connected to the lower part of the fixed block 64. The limiting member 66 is L-shaped to limit the range of motion of the fixed block 64 and the movable part 62, ensuring the stable fixing of the connecting column 56 and the scraper 55 during normal operation. At the same time, it facilitates the disassembly of the scraper 55, enabling quick repair and replacement, thus improving maintenance efficiency. A limiting groove 67 is provided on the outer side of the support rod 52, and the lower part of the limiting member 66 is inserted into the inner wall of the limiting groove 67. The lower part of the fixing cap 61 is provided with a groove, and the groove on the fixing cap 61 fits against the outer side of the scraper 55 and the connecting column 56, cooperating with the limiting member 66 to provide positioning for the limiting member 66, ensuring the normal operation of the disassembly assembly 6, and enabling the connecting column 56 and the scraper 55 to be operated accurately during the fixing and disassembly process.

[0037] Working principle: When in use, after the sludge enters the machine body 2, the drive motor 3 starts. Under the gravity concentration, some water is initially separated. At the same time, the back pressure plate 4 forms internal pressure, which pushes the sludge to further dewater during the process. The filtrate is discharged from the filter gap formed by the fixed ring and the movable ring, and the sludge cake is discharged from the end of the dewatering section, realizing the core function of sludge dewatering. This part of the technology is existing technology.

[0038] When the drive motor 3 is working, its output shaft drives the back pressure plate 4 to rotate. Multiple sets of cleaning components 5 are arranged in a circular array on the outer side of the back pressure plate 4. During the rotation, the scraper 55 can adhere to the surface of the machine body 2 and scrape off the sludge attached to the surface of the machine body 2, avoiding sludge accumulation and reducing the cleaning burden on workers.

[0039] When the scraper 55 is worn or damaged and needs to be replaced, push the moving part 62, compress the spring 65, and the moving part 62 will drive the limiting part 66 to disengage from the limiting groove 67, so that the fixing cap 61 is separated from the support rod 52. The fixing cap 61 is fixedly connected to the connecting column 56 by screws. At this time, the connecting column 56 and the scraper 55 can be pulled out from the slot 54. After unscrewing the screws, the connecting column 56 and the scraper 55 can be quickly repaired and replaced, which improves maintenance efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
