[0002] Wastewater treatment processes generate a large amount of sludge, which is bulky and has a high water content. In order to remove the water from the sludge, filter press equipment is usually used to remove the wastewater. The filter press equipment applies pressure to make the water in the sludge pass through the filter cloth, while the solid particles are trapped in the filter chamber to form a filter cake.

It addresses the problem that existing belt sludge dewatering machines often use fewer than five squeeze rollers, resulting in incomplete dewatering due to insufficient pressure. The belt filter press for sludge dewatering features an upper and lower filter belt that sequentially passes around a first, second, and third squeeze roller in the squeeze roller dewatering zone. The first and third squeeze rollers are located at the upper end of the upper filter belt, and the second squeeze roller is located at the lower end of the lower filter belt. Multiple arc-shaped elements are arranged circumferentially on the outer surfaces of the first, second, and third squeeze rollers. One end of each arc-shaped element is hinged to the outer surface of the squeeze roller, and an elastic sheet is provided between the arc-shaped element and the outer surface of the squeeze roller.

For example, Chinese Patent Publication No. CN213623798U discloses a belt filter press for sludge dewatering, describing its working principle, so it will not be elaborated further. The compressor frame 1 is equipped with a scraping mechanism 9, which includes auxiliary... Structure 10, the scraping mechanism 9 includes a rotating column 91, which is rotatably connected to the inner walls of the front and rear sides of the compressor frame 1 via bearings. An adjusting disc 92 is fixedly connected to the rear end of the rotating column 91, and a torsion spring 93 is fixedly connected to the outer wall of the front side of the adjusting disc 92. A first scraper plate 94 is engaged with the inner wall of the side of the rotating column 91. The first scraper plate 94 is used to scrape the residual sludge on the surface of the upper filter belt 7. A movable column 95 is rotatably connected to the inner walls of the front and rear sides of the compressor frame 1 via bearings, and a second scraper plate 96 is engaged with the inner wall of the side of the movable column 95.

[0025] Reference Figures 2-4 A frosted pad is fixedly connected to the outer side wall of the adjusting disc 92. The rotating column 91 penetrates the rear outer wall of the compressor frame 1. The end of the torsion spring 93 away from the adjusting disc 92 is fixedly connected to the rear outer wall of the compressor frame 1. The torsion spring 93 generates torque on the adjusting disc 92. There are two adjusting discs 92, which are fixedly connected to the rear ends of the movable column 95 and the rotating column 91, respectively. The first scraper 94 contacts the outer side wall of the upper filter belt 7. The first scraper 94 scrapes the sludge off the surface of the upper filter belt 7. The second scraper 96 contacts the outer side wall of the lower filter belt 6. The second scraper 96 scrapes the sludge remaining on the surface of the lower filter belt 6. The first scraper 94 contacts the outer side wall of the upper filter belt 7. The second scraper 96... The lower filter belt 6 is in contact with the outer side wall of the side. The counterclockwise motor 2 is fixedly connected to the outer rear wall of the compressor frame 1, and the clockwise motor 3 is fixedly connected to the outer rear wall of the compressor frame 1. By setting the clockwise motor 3 to drive some of the multi-rollers 5 to rotate clockwise, the lower track 6 moves clockwise. The outlet 4 is opened on the inner bottom wall of the compressor frame 1. The multi-rollers 5 are rotatably connected to the inner front and rear sides of the compressor frame 1 through bearings. There are several multi-rollers 5. One of the multi-rollers 5 is fixedly connected to the output end of the counterclockwise motor 2 through a coupling. By setting the counterclockwise motor 2 to drive some of the multi-rollers 5 to rotate counterclockwise, the upper filter belt 7 moves counterclockwise. The lower filter belt 6 and the upper filter belt 7 are respectively rolled on the multi-rollers 5. The inner bottom wall of the compressor frame 1 is provided with a discharge port 97.

[0026] Reference Figures 3-4The auxiliary structure 10 includes a positioning groove 100, which is formed on the inner side wall of the rotating column 91. An adjusting plate 101 is slidably connected to the top inner wall of the first scraper plate 94. An insert plate 102 is fixedly connected to the right outer wall of the adjusting plate 101. The first scraper plate 94 and the rotating column 91 are locked together by the insert plate 102. A compression spring 103 is fixedly connected to the left outer wall of the adjusting plate 101. The compression spring 103 generates a continuous thrust on the adjusting plate 101. The insert plate 102 is locked onto the right inner wall of the rotating column 91. The end of the compression spring 103 away from the adjusting plate 101 is fixedly connected to the inner side wall of the first scraper plate 94. Abrasive plates are fixedly connected to the left and right outer walls of the adjusting plate 101.

[0027] Working principle: During the dewatering and filtration process of sludge, the torsion spring 93 twists the adjusting plate 92 to rotate, which in turn drives the rotating column 91 to rotate. The rotating column 91 causes the first scraper 94 to slide against the moving surface of the upper filter belt 7, so that the sludge on the upper filter belt 7 is scraped off and falls to the outside of the discharge port 97. At the same time, the second scraper 96 slides against the moving surface of the lower filter belt 6, so that the sludge on the lower filter belt 6 is scraped off and falls to the outside of the discharge port 97. During long-term use, the impurities remaining on the scraper 94 can be cleaned or replaced by pulling the adjusting plate 101 to move the insert plate 102. The insert plate 102 moves and disengages from the inner wall of the rotating column 91. Then, the first scraper 94 moves upward and is pulled out from the positioning groove 100.

[0028] 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.
