Sliding bases 2 are respectively installed at the bottom of both sides of the gantry frame. Multiple traveling wheels 22 are mounted on the sliding base 2, and servo motors 21 driving the traveling wheels 22 are also installed. The servo motors 21 on both sides of the sliding base 2 can be controlled by a controller to move synchronously.

[0026] In a specific implementation, guide rails 12 for limiting the travel wheel 22 are also installed on both sides of the filter press 1; specifically, the guide rails 12 are grooves that ensure the travel wheel 22 travels in a straight line.

[0027] In this embodiment, a crossbeam is installed on the side wall of the bracket 3, and scraper guide grooves 32 are symmetrically fixed on the crossbeam; sliding gaps are reserved between the two ends of the mud cleaning scraper 5 and the bottom of the two scraper guide grooves 32; the thickness direction of the mud cleaning scraper 5 is also reserved with the scraper guide grooves 32.

[0028] Two cleaning scrapers 5 are symmetrically installed below the top plate 31, and the upper ends of the cleaning scrapers 5 are respectively connected to the telescopic ends of the telescopic cylinder 4; a position sensor 8 (specifically designed as two) for detecting the position of the filter plate 11 on the filter press 1 is also installed on the gantry frame and between the two cleaning scrapers 5; wherein the position sensor 8 is one of the ultrasonic position sensor, infrared position sensor, and laser position sensor.

[0029] In use, the position sensor 8 detects the position of the filter press plate 11, thereby controlling the servo motor 21 to adjust the mud cleaning scraper 5 on the gantry frame to be symmetrically arranged above both sides of the filter press plate 11; wherein the telescopic cylinder 4 adjusts the raising and lowering of the mud cleaning scraper 5 to scrape off the silica mud attached to the filter press plate 11.

[0030] In this embodiment, reference Figure 1 Two guide rods 41 are installed on the top of the sludge scraper 5. The upper end of the guide rod 41 passes through the top of the top plate 31. A bushing adapted to the guide rod 41 is installed on the top plate 31. When the telescopic cylinder 4 adjusts the lifting and lowering of the sludge scraper 5, the guide rods 41 can be used to maintain the vertical lifting and lowering state of the sludge scraper 5. The telescopic cylinder 4 is an electric telescopic cylinder or a pneumatic cylinder, which is convenient to move with the gantry frame. In addition, in this embodiment, the scraper guide groove 32 is a U-shaped seat, which has a vertical through groove adapted to the wall thickness of the sludge scraper 5, which also helps to limit the vertical lifting and lowering state of the sludge scraper 5.

The telescopic cylinder 4 adjusts the descent of the cleaning scraper 5 to clean the silica mud attached to the filter press plate 11. At the same time, the air pump 6 supplies air to the pulse nozzle 7 installed on the cleaning scraper 5, so as to assist the inclined scraper section of the cleaning scraper 5 to quickly scrape off the silica mud on its side wall by pneumatic means. The scraped silica mud falls directly into the equipment, and there is a mud discharge port on the bottom side wall of the equipment.
