Description

Technical Field

[0001] This utility model relates to the technical field of scraper and suction sludge machines, specifically to a sludge suction system for a clogging-proof scraper and suction sludge machine. Background Technology

[0002] The sludge scraper is a sludge treatment device used in sedimentation tanks for sewage treatment, tap water purification and other scenarios. Its main function is to scrape off the sludge at the bottom of the tank and separate the floating scum on the water surface through mechanical devices, so as to separate the sludge from the water. The sludge scraper is the core equipment for removing sludge from the bottom of the tank, and the smoothness of its sludge suction components directly determines the sludge treatment efficiency. As disclosed in announcement number CN219272242U, a clog-resistant sludge suction scraper includes a cylinder. A handle is fixedly connected to the surface of the cylinder, a sludge suction pipe is provided on the surface of the cylinder, and a motor is fixedly connected to the surface of the cylinder. The output shaft of the motor passes through and is rotatably connected to the inner wall of the cylinder. A rotating shaft is fixedly connected to the bottom end of the motor output shaft, and an anti-clogging mechanism is provided at the bottom end of the rotating shaft. The anti-clogging mechanism includes a filter plate, which is fixedly connected to the bottom surface of the cylinder. When the rotating shaft is driven by the motor to rotate, the protective sleeve drives the scraper and the ring to rotate accordingly, thereby cleaning the bottom surface of the sedimentation tank. The sludge is filtered through the filter plate, and the cutting blades cut the sludge that enters the protective sleeve, breaking down other objects contained in the sludge until it can pass through the filter plate, thus avoiding the phenomenon of clogging the pipe and affecting the normal use of the sludge suction scraper. However, existing technologies have problems such as large sludge pieces covering the outside of the suction port, causing blockages, making it inconvenient to crush large sludge pieces, and the filter screen is also prone to clogging during long-term use, affecting the efficiency of sludge suction. For example, the comparative patents listed above have this problem. Therefore, this utility model provides a clogging-proof sludge suction system for a scraper and suction machine to solve the problems mentioned above. Utility Model Content

[0015] Please see Figures 1-6 The present invention provides the following technical solution: To address the problems in existing technologies where large sludge pieces can clog the outside of the suction port, hindering sludge crushing and causing filter screen blockage over time, thus affecting suction efficiency, this solution provides an anti-clogging scraper suction system. The system comprises a suction pipe body 1 and a negative pressure pipe 2 connected to the top of the suction pipe body 1. The bottom of the suction pipe body 1 is the suction port, which is equipped with a funnel-shaped guide shroud. A detachable filter plate 4 is fitted inside the guide shroud. A crushing component is located at the bottom of the filter plate 4, and a scraping and cleaning component is located at the top of the filter plate 4. A stainless steel liner 14 is fixedly installed on the inner wall of the suction pipe body 1. like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a funnel-shaped guide shroud is provided at the lower end of the sludge suction pipe body 1. The negative pressure pipe 2 at the upper end of the sludge suction pipe body 1 is connected to the external negative pressure sludge suction assembly of the sludge scraper. At the same time, a filter plate 4 is installed in the guide shroud. After the negative pressure system is started, a negative pressure environment is formed inside the sludge suction pipe body 1. The sludge enters the interior of the sludge suction pipe body 1 through the guide shroud. The sludge is then crushed by a crushing assembly provided at the lower end of the filter plate 4. The crushing assembly consists of a crushing blade 8 and an mounting block 9 fixed to the upper end of the crushing blade 8. The mounting block 9 is fixed to the lower end of the filter plate 4. The crushing blade 8 crushes large pieces of sludge to prevent large pieces of sludge from covering the outside of the filter plate 4 and causing blockage. Simultaneously, combined with the setting of the scraping and cleaning components, such as Figure 5 and Figure 6 As shown, the scraping and cleaning assembly includes a stepper motor 10 mounted on the upper end of the suction pipe body 1 for driving, a movable connecting shaft 11 fixed to the output end of the stepper motor 10, and a cleaning scraper 12 fixed to the lower end of the movable connecting shaft 11. The cleaning scraper 12 is placed in a guide shroud, and an elastic scraper 13 is fixedly connected to the lower end of the cleaning scraper 12. The elastic scraper 13 is in close contact with the inner side of the filter plate 4. When the stepper motor 10 mounted on the upper end of the suction pipe body 1 is started, the stepper motor 10 and the movable connecting shaft 11 drive the cleaning scraper 12 to rotate, so that the elastic scraper 13 scrapes the sludge on the inner side of the filter plate 4. The treatment further enhances the anti-clogging effect. Moreover, a stainless steel liner 14 is fixedly attached to the inner side of the suction pipe body 1. The stainless steel liner 14 improves the overall wear resistance, reduces inner wall wear, and extends the service life of the suction pipe body 1. In addition, after use, the fastening bolt 7 used for limiting can be removed, the fastening bolt 7 is separated from the mounting column 5, and the fastening bolt 7 is moved out of the screw hole 6, thereby loosening the limiting effect between the mounting column 5 and the guide shroud. Then, the filter plate 4 is removed from the guide shroud, and the filter plate 4 drives the mounting column 5 to move out of the mounting hole 3 for thorough cleaning or replacement.
