[0026] The intermediate press 11 comprises a slurry inlet 18 and a water receiving trough 19 . The slurry inlet 18 is located in the middle area opposite to the water receiving trough 19 and coincides with the center position of the slurry funnel 21 . The water receiving trough 19 is the same as the water receiving trough 19 of the upper press 10 .
[0027] The lower press 12 includes a slurry inlet 18 and a water receiving trough 19. The slurry inlet 18 is the same as the slurry inlet 18 of the intermediate press 11. The water receiving trough 19 is similar to the water receiving trough 19 of the upper intermediate press 11. The difference is that the water receiving trough 19 of the lower press 12 is connected to the clean water pipe 7.
[0028] The slurry discharge barrel 14 contains many slurry discharge holes 22, the radius of the slurry discharge holes 22 of the upper press 10 is twice that of the middle press 11, and the radius of the slurry discharge holes 22 of the middle press 11 is twice that of the lower press 12; the slurry collecting barrel 15 includes multiple slurry discharge ports 23 directly below, and the maximum distance of the slurry discharge ports 23 is less than the maximum distance of the water receiving trough 19; the press support 17 includes a support rod 24 and a support groove rod 20; the load-bearing frame 8 includes a load-bearing platform 25, a load-bearing column 26, and a slurry funnel 21; the center position of the load-bearing platform 25 of the upper press 10 and the middle press 11 includes a reserved through hole, and the lower side of the reserved through hole completely overlaps with the slurry funnel 21.

[0039] Step 1: Send the waste mud to the slurry tank 1, open the feed valve 3, and start the feed pump 4 through the control console 9. The waste mud can flow into the slurry inlet of the upper press 10 through the feed pipe 2.
[0040] Step 2: Operate the upper press through the control console 9 to push the filter press piston 13, compress the space of the slurry discharge barrel 14 to filter the waste mud for the first time, and repeatedly push the filter press piston 13 to maximize the filtration of the upper press 10.
[0041] Step 3: The waste slurry from the upper press 10 enters the intermediate press 11 through the water receiving trough 19, and the intermediate press 11 is operated by the control console 9 to push repeatedly. When the waste slurry from the intermediate press 11 enters the lower press 12 through the water receiving trough 19, the lower press 12 is operated by the control console 9 to push the filter piston 13 repeatedly to maximize filtration.
[0042] Step 4: By gradually purifying the mud water quality, the slurry can flow out through the clean water pipe and can be collected for use. The cake outlet door 16 of the strong source filter press 5 is opened through the control console 9, and the filter press piston 13 is operated to push the mud cake into the mud cake barrel 6 to achieve solid-liquid separation.
[0043] According to the above-mentioned upper, middle and lower press machine discharging barrel diagram Figure 3 It can be found that the mud filter pressing dehydration and solidification system controls the mud purity through the size of the mud outlet hole 22. The finer the mud outlet hole 22, the stronger the water purification ability. In addition, whether it can purify sewage and composite water can be determined according to actual conditions and play a certain positive role, indicating that this system has certain flexibility, applicability and practicality.
