Then, the first hydraulic cylinder 5 and the second hydraulic cylinder 8 are controlled to move in opposite directions by a preset distance, and at the same time, the first dewatering execution unit 6 and the second dewatering execution unit 9 are driven by the first hydraulic cylinder 5 and the second hydraulic cylinder 8 to move in opposite directions, and metal powder slurry between the first hydraulic cylinder 5 and the second hydraulic cylinder 8 is extruded, wherein the moving distance of the first dewatering execution unit 6 and the second dewatering execution unit 9 can always ensure that the second water draining hole 1122 is positioned between the first sealing ring 93 and the second sealing ring 94 in the second dewatering execution unit 9, the third water draining hole 1123 is positioned between the first sealing ring 93 and the second sealing ring 94 in the first dewatering execution unit 6, water in the metal powder slurry is separated from the metal powder under the action of extrusion force, the formed wastewater enters the first cylinder 91 through the filter plate 92, and most of the metal powder is reserved in a space between the second dewatering execution unit 9 and the second dewatering execution unit 9, and the dewatered metal powder forms a round cake shape;
Then, the first hydraulic cylinder 5 pulls the first dewatering executing unit 6 to move in a direction away from the second dewatering executing unit 9 until the first hydraulic cylinder returns to the original position, at the moment, the third hydraulic cylinder 12 pulls the third reinforcing plate 111 to move in a direction close to the second power box 2 until the filter plate 92 is exposed out of the second cylinder 1121, the metal powder cakes formed in the second cylinder 1121 lose the bearing of the second cylinder 1121 and fall under the action of self gravity, a metal powder cake collecting cylinder is arranged in the middle area of the first power box 1 and the second power box 2, the metal powder cakes just fall in the metal powder cake collecting cylinder, and the metal powder cake collecting cylinder is far away from the middle area of the first power box 1 and the second power box 2 after the powder cake collecting cylinder finishes collecting work, so that the preliminary cold pressing and drying operation of the metal powder slurry is finished;
Then, carrying out next cold pressing and drying operation on the metal powder slurry, driving the first dewatering execution unit 6 to move towards the direction close to the second dewatering execution unit 9 again by the first hydraulic cylinder 5 until reaching a preset position, pushing the second dewatering mechanism 11 to reset by the third hydraulic cylinder 12, and then injecting a certain amount of metal powder slurry into a closed space formed by the first dewatering execution unit 6, the second dewatering execution unit 9 and the second cylinder 1121 again through the feeding pipe 10;
Before cold pressing the metal powder slurry again, starting the servo motor 1138 through a control box, and stopping operation after each time the servo motor 1138 rotates by a preset angle due to program control, wherein the output shaft of the servo motor 1138 is provided with a locking mechanism which can unlock the output shaft of the servo motor 1138 when the servo motor 1138 operates, and immediately completing locking the output shaft of the servo motor 1138 when the servo motor 1138 stops operating, wherein the preset angle enables two adjacent dehydration units 1133 to accurately exchange positions; the servo motor 1138 drives the gear 1139 to drive the toothed ring 1132 to rotate a preset angle, so that the adjacent two dewatering units 1133 exchange positions, after the next dewatering unit 1133 enters the position, the waste liquid inlet 11332 on the outer wall of the next dewatering unit is communicated with the annular sliding block 1134 and the communicating pipe 1137 on the opposite position, meanwhile, in the process of exchanging positions of the adjacent two dewatering units 1133, the push rod b6 in the filter pressing assembly one 11334 continuously slides along the surface of the arc-shaped driving block one 1142, the push rod a2 climbs along the slope of one end of the arc-shaped driving block two 1152, the push rod a2 pushes the extrusion block a1 to approach the direction of the filter pressing cylinder b3 under the action of the arc-shaped driving block two 1152 until a gap with preset width appears between the filter pressing cylinder b3 and the opposite side wall of the extrusion block a1, the gap is used for providing a space for forming a metal powder cake for residual metal powder in waste water, the size of the space can be adjusted according to the actual use requirement, the requirement of forming the metal cake by extruding the residual metal powder in the waste water can be just satisfied, for example, the length of the push rod a2 or the length of the arc-shaped driving block two different thickness blocks are changed, the gap between the arc-shaped driving block a2 and the opposite side wall is changed, after the waste water between the press cylinder b3 and the pressing block a1 is pressed, the water enters the press cylinder b3 through a filtering hole b4 of the press cylinder b3, which is far away from the outer wall surface of the push rod b6, and then is discharged through a liquid outlet b5 at the bottom of the press cylinder b3, and the pressed water continuously flows into a filtrate collecting cylinder arranged right below the filtrate collecting cylinder through a metal cake outlet 11333 because the liquid outlet b5 is positioned in the metal cake outlet 11333, and the filtrate collecting cylinder is used for post-treatment of metal powder slurry;
When the end part of the push rod b6 in one dewatering unit 1133 enters the position of the area between the two ends of the first driving ring 1141, the push rod b6 loses the pushing action of the first arc-shaped driving block 1142, the elastic force of the spring b7 pushes the push rod b6 to move towards the direction close to the mounting plate b1, all the metal dredging needles b2 completely penetrate through the filtering holes b4 at the corresponding positions to push out impurities blocked in the filtering holes b4, at the moment, the positions of the metal cake outlets 11333 are completely exposed, then the push rod a2 climbs from the lower position to the highest position along the outer wall of the protruding block 1153, the pressing block a1 continues to slide towards the direction of the press-filter cylinder b3 until the end face of the pressing block a1 close to the press-filter cylinder b3 and one side wall of the metal cake outlets 11333 are on the same plane, and at the same time, the pressed metal powder cake in a cake shape is pushed to the position of the metal cake outlets 11333 and falls under the self gravity effect, and secondary collection of metal powder in the metal powder slurry is completed.
