AI Technical Summary
During the river silt process of existing filter presses, the residual silt on the filter plate will cause the next set of filter presses to have poor effect, resulting in equipment blockage and reduced efficiency.
An integrated filter press for river channel silt is designed, equipped with erosion components and sludge scraping components. The rinse assembly uses a water spraying faucet to rinse the silt on the filter plate. The sludge scrapes the silt on the side of the filter plate through the upper and lower scrapers to ensure that the filter plate is clean and improve the filter pressing effect.
By effectively scraping and eroding the sludge on the filter plate, preventing sludge residue from affecting the next set of operations, the efficiency and quality of river dredging are improved, and the continuous and efficient operation of the filter press is ensured.

[0025] Please refer to Figures 1-4 , an integrated filter press for river dredging, including a filter press table 1. There are two groups of pressing plates 2 arranged on the inner wall of the filter press table 1. A plurality of large cylinders 3 are slidably connected between the two groups of pressing plates 2 on the filter press table 1. A horizontally arranged large cylinder 3 is fixedly installed on the inner wall of the filter press table 1. The piston rod of the large cylinder 3 is fixedly connected to the side of one of the pressing plates 2. A gantry 7 is fixedly installed on the top of the filter press table 1, and a small cylinder 8 is fixedly installed on the top of the gantry 7. It further includes:
[0026] A scouring assembly, which is installed at the bottom of the gantry 7 and is used to scour the remaining silt on the filter plate 4.
[0027] A mud scraping assembly, which is installed at the upper and lower ends of the scouring assembly of the gantry 7 and is used to remove the silt on the side of the filter plate 4.
[0028] Sliding grooves 5 are opened on both inner walls of the filter press table 1. Parallel sliders 6 are fixedly connected to the middle positions on both sides of the plurality of filter plates 4 and the pressing plates 2. The two groups of parallel sliders 6 are respectively slidably clamped in the two groups of sliding grooves 5. During use, the piston rod of the large cylinder 3 starts to move to push one of the pressing plates 2 to slide on the inner wall of the filter press table 1. During the sliding process of the pressing plate 2, the parallel sliders 6 on both sides slide in the two groups of sliding grooves 5.
[0029] A plurality of filter plates 4 are slidably connected between the two groups of pressing plates 2. One of the pressing plates 2 is slidably connected to the inner wall of the filter press table 1, and the other pressing plate 2 is fixedly connected to the inner wall of the filter press table 1. During the sliding process of the pressing plate 2, it starts to fit with one of the pressing plates 2, and then the three filter plates 4 are pushed to the side of the other pressing plate 2 by the thrust of the large cylinder 3, so that the two pressing plates 2 gradually tighten to squeeze out the water in the silt of the three filter plates 4.
[0030] Four vertical table legs 13 are fixedly provided at the four corners corresponding to the bottom of the filter press table 1. A collecting plate 14 for collecting the hardened silt is fixedly connected between the four table legs 13 corresponding to the directly below of the filter press table 1. Then, the large cylinder 3 is withdrawn to its original position, and the three filter plates 4 are separated to make the solidified silt fall onto the collecting plate 14 at the bottom of the filter press table 1 by gravity for convenient collection.
[0031] The two ends of the gantry 7 are fixedly connected with integrated vertical plates at the corresponding bottom positions. The gantry 7 is fixedly connected to the top of the filter press 1 through two groups of vertical plates. Then the small cylinder 8 on the gantry 7 is started, and the piston rod on the small cylinder 8 pushes the synchronous horizontal plate 9 to move slowly downward.
[0032] The scraper assembly includes a synchronous cross plate 9, an upper scraper 11 and a lower scraper 12. The piston rod on the small cylinder 8 extends to the bottom of the gantry 7 and is fixedly connected to the synchronous cross plate 9. The upper scraper 11 is fixedly connected to one side of the synchronous cross plate 9 near the top. The bottom of the synchronous cross plate 9 is fixedly connected to an inclined lower scraper 12. The end positions of the upper scraper 11 and the lower scraper 12 away from the synchronous cross plate 9 are tightly fitted to one side of the pressure plate 2. The synchronous cross plate 9 synchronously drives the lower scraper 12 to fit one side of the filter plate 4 through the movement of the piston rod and scrapes off the solidified sludge on the side of the filter plate 4.
[0033] The flushing assembly includes three groups of water spray taps 10. Three groups of water spray taps 10 are fixedly connected to one side of the synchronous cross plate 9 corresponding to the lower part of the upper scraper 11 and are equidistantly distributed. During the downward sliding process, the three groups of water spray taps 10 spray water outward to flush the residual solid sludge remaining on the pressure plate 2, and then the residual mushroom body sludge is scraped off for the next time through the upper scraper 11.
[0034] Working principle: When in use, the piston rod on the large cylinder 3 starts to move to push one group of pressure plates 2 to slide on the inner wall of the filter press 1. During the sliding process of the pressure plate 2, the parallel sliders 6 on both sides slide in the two groups of slide grooves 5. During the sliding process, the pressure plate 2 begins to fit with one group of pressure plates 2, and then the thrust of the large cylinder 3 pushes the three groups of filter plates 4 to the side of the other group of pressure plates 2, so that the two groups of pressure plates 2 gradually tighten to force the moisture of the sludge of the three groups of filter plates 4 to dry, and then withdraw to the original position through the large cylinder 3, and push away The three groups of filter plates 4 allow the solidified sludge to fall to the bottom of the filter press 1 by gravity, and then the small cylinder 8 is started. The piston rod on the small cylinder 8 pushes the synchronous cross plate 9 to move slowly downward. The synchronous cross plate 9 synchronously drives the lower scraper 12 to fit one side of the filter plate 4 and scrape off the solidified sludge on the side of the filter plate 4 through the movement of the piston rod. In the process of sliding downward, the three groups of water spraying faucets 10 spray water outward to flush the remaining residual solid sludge on the pressing plate 2, and then the residual mushroom body sludge is scraped off for the next time through the upper scraper 11.
