[0042] like Figure 1-8 As shown, before the sewage is connected to the input channel 5, the crankshaft 503 is driven to rotate by the transmission motor 502, thereby driving the bar frame 505 to move back and forth, and the hydraulic piston A504 is retracted and extended, and the hydraulic piston B506 is driven to extend and contract through liquid displacement, and the movable frame 507 is driven to move forward and backward, so that the movable frame 507 and the fixed frame 508 cooperate with the one-way rotating plate 509 to form a one-way variable volume conveying mechanism, and the sewage is continuously conveyed backward to the upper channel 3; during the backward movement of the bar frame 505, it will contact the trigger plate 8 and push the trigger plate 8 backward;

[0043] When the telescopic end of the control piston 602 moves backward in cooperation with the trigger plate 8, the control piston 602 is squeezed to input the liquid material in the control piston 602 through the one-way valve B604 into the interior of the upper channel 3 for filling; then, when the control piston 602 automatically resets in cooperation with the spring, the liquid material is supplemented and sucked into the control piston 602 through the one-way valve A603 by negative pressure;

[0044] When the connecting rod 704 moves backward with the trigger plate 8, the powder feeder 703 is pushed backward, and the powder in the powder hopper 701 falls into the vertical groove of the powder feeder 703. Then the spring outside the connecting rod 704 provides a reset effect, and the powder feeder 703 moves to Figure 8 When the bar frame 505 moves to the front, the air pump 9 is squeezed, and the air in the air pump 9 is input into the vertical groove of the powder feeder 703 through the one-way valve C705, thereby generating a pressurization effect, and the powder is input into the upper channel 3 through the input hopper 702.

[0045] Embodiment 2: Based on Embodiment 1, the selection of the infusion device 6 and the powder dispenser 7 is selected according to the material used. If the flocculant and the deodorant are both powder products, the infusion device 6 can be replaced with the powder dispenser 7 and its associated accessories for automatic addition; conversely, if liquid products are required, the powder dispenser 7 and its associated accessories can be replaced with the infusion device 6 to perform liquid input;

[0046] The operation of both the infusion device 6 and the powder feeder 7 is triggered by the bar frame 505, and no additional power source is required. In addition, the reciprocation of the bar frame 505 is stable, and the reciprocating speed is balanced with the conveying speed, so the added flocculant and deodorant can also stably maintain a corresponding ratio.

[0047] Embodiment 3: Based on Embodiment 1, water passes through the upper channel 3 and enters the interior of the filter press cylinder 402 to be transported downward, the second motor 302 is started to drive the linkage shaft 301 to rotate, and the linkage shaft 301 cooperates with the bevel gear to drive each group of spiral filter presses 403 to rotate, and the spiral filter presses 403 provide a filtering function to transport the mud downward, and then the water passes through the filter press cylinder 402 and is squeezed into the intermediate bin 2, and the water is discharged from the water outlet 202, and the sludge enters the lower channel 1;

[0048] The rotation of the spiral filter press 403 can also continuously scrape away impurities on the inner wall of the filter press cylinder 402 to prevent clogging;

[0049] Starting the first motor 104 to drive the screw propeller 103 to rotate can collect the sludge and transport it backward in a centralized manner. When the accumulated sludge is too much, it can withstand the conveying force of the screw propeller 103 and move backward, enter the pressure valve 105, and after continuous pressure increase, the wedge-shaped valve molds 106 on both sides are opened to be discharged outward.

[0050] Specific usage and function of this embodiment: In the present invention, when in use, the sewage is connected to the front of the input channel 5, and the transmission motor 502 drives the crankshaft 503 to rotate, thereby driving the bar frame 505 to move back and forth, and the hydraulic piston A504 is retracted, and the hydraulic piston B506 is driven to extend and contract through liquid replacement, and the movable frame 507 is driven to move forward and backward, so that the movable frame 507 and the fixed frame 508 cooperate with the one-way rotating plate 509 to form a one-way variable volume conveying mechanism, and the sewage is continuously conveyed backward to the upper channel 3;

[0051] When the bar frame 505 moves backward, it contacts the trigger piece 8 and pushes backward toward the trigger piece 8;

[0052] When the telescopic end of the control piston 602 moves backward in cooperation with the trigger plate 8, the control piston 602 is squeezed to input the liquid material in the control piston 602 through the one-way valve B604 into the interior of the upper channel 3 for filling; then, when the control piston 602 automatically resets in cooperation with the spring, the liquid material is supplemented and sucked into the control piston 602 through the one-way valve A603 by negative pressure;

[0053] When the connecting rod 704 moves backward with the trigger plate 8, the powder feeder 703 is pushed backward, and the powder in the powder hopper 701 falls into the vertical groove of the powder feeder 703. Then the spring outside the connecting rod 704 provides a reset effect, and the powder feeder 703 moves to Figure 8 When the bar frame 505 moves to the front, the pump 9 is squeezed, and the air in the pump 9 is input into the vertical slot of the powder feeder 703 through the one-way valve C705, thereby generating a pressurizing effect, and the powder is input into the upper channel 3 through the input hopper 702;

[0054] The sewage is treated by adding flocculants and deodorants, and at the same time, the sewage passes through the upper channel 3 and enters the interior of the filter press cylinder 402 to be transported downward. The second motor 302 is started to drive the linkage shaft 301 to rotate. The linkage shaft 301 cooperates with the bevel gear to drive each group of spiral filter presses 403 to rotate. The spiral filter press 403 provides a filtering function to transport the muddy material downward, and then the water passes through the filter press cylinder 402 and is squeezed into the middle bin 2. The water will be discharged from the water outlet 202, and the sludge will enter the lower channel 1; the rotation of the spiral filter press 403 can also continuously scrape off the impurities on the inner wall of the filter press cylinder 402 to prevent blockage;

[0055] The first motor 104 is started to drive the screw propeller 103 to rotate, so that the sludge can be collected and transported backward in a centralized manner. When the amount of sludge accumulated is too much, it can withstand the conveying force of the screw propeller 103 and move backward, enter the pressure valve 105, and after continuous pressure increase, the wedge-shaped valve molds 106 on both sides are opened to be discharged outward;

[0056] Finally, mud and liquid separation and deodorization are achieved;

[0057] The overall structure of the device is narrow, which is convenient for arrangement and use. The pipes can be replaced by bent pipes, and the input and output pipes can be connected together with integrated pipes to support the synchronous input or output of multiple groups of equipment.
