Through the provided transport mechanism, the sludge after being laid falls onto the filter cloth A350. The sludge is transported through the filter cloth A350 and cooperates with the first filter press mechanism to perform preliminary filter dewatering of the sludge.

A hydraulic rod A420 is fixed to the top of the mounting plate 410, and a drive plate 430 is fixed to the bottom of the hydraulic rod A420. By providing a drive mechanism, during the filter press operation, the hydraulic rod A420 drives the drive plate 430 to move downward, and the downward movement of the drive plate 430 drives the first filter press mechanism to move downward, thereby driving the first filter press mechanism to cooperate with the drive mechanism to perform filter press dewatering operation.

[0030] Specifically, the first filter press mechanism includes a conveyor frame B510, which is bolted to the bottom of the drive plate 430. A geared motor B520 is bolted to one side of the conveyor frame B510. A drive shaft B521 is provided at the output end of the geared motor B520. A drive roller B530 is fixed to the outside of the drive shaft B521. A perforated conveyor belt B540 is provided to the outside of the drive roller B530. A filter cloth B550 is fixed to the outside of the perforated conveyor belt B540. Multiple support rollers B560 are rotatably connected inside the conveyor frame B510. A scraper plate B570 is fixed to the inner wall of the conveyor frame B510. With the first filter press mechanism, during the filter press operation, the drive mechanism drives the first filter press mechanism to move downward. The filter cloth B550 and the filter cloth A350 cooperate to perform preliminary filter press dewatering on the sludge.

[0031] Working Principle: During operation, the equipment is controlled via control panel 110. Sludge enters the spreading machine 230 through the feeding pipe 220. The spreading machine 230 spreads the sludge, which then falls onto the filter cloth A350. The geared motor A320 drives the drive shaft A321 to rotate, which in turn drives the drive roller A330. The drive roller A330 then drives the porous conveyor belt A340 and the filter cloth A350 to rotate, thus allowing the sludge to pass through the filter cloth A350. During transportation and filter pressing operations, the hydraulic rod A420 drives the drive plate 430 downwards. The downward movement of the drive plate 430 causes the first filter pressing mechanism to move downwards, thereby causing the filter cloth B550 to press onto the sludge. The filter cloth A350 then compresses the sludge. The geared motor B520 drives the drive shaft B521 to rotate, which in turn drives the drive roller B530. The rotation of the drive roller B530 then drives the porous conveyor belt B540, which in turn moves the filter cloth... B550 rotates, and the sludge undergoes preliminary dewatering and filtration through the cooperation of filter cloths B550 and A350. Water from the first stage of filtration is collected in the collection tank A140 and discharged through the drain pipe A141. Sludge on filter cloth B550 is scraped off by scraper plate B570 and falls into the guide hopper 610. The filtered sludge enters the filter press chamber 620 through the guide hopper 610. Hydraulic rod B720 moves the pressure plate A730, which, in conjunction with the pressure plate A730... The pressure plate B760 performs the second stage of filtration and dewatering of the sludge. The filtered water enters the water collection tank B640 through the filter press box 620 and is finally discharged through the drain pipe B641. After the filtration operation is completed, the hydraulic rod C750 drives the pressure plate B760 to move to the side of the discharge tank 650. The pressure plate A730 pushes the sludge to the discharge tank 650 and finally discharges the sludge through the discharge tank 650. The above mechanisms work together to perform multi-stage filtration and dewatering of the sludge, resulting in a low moisture content of the sludge after filtration and dewatering.

Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and accompanying drawings.
