These units consist of multiple sets of filter plates connected end-to-end, each with a feed hole and a material chamber. The feed hole communicates with the material chamber. During operation, a feed pump pumps material from the feed hole into the material chamber, filling it completely.

In this invention, a feed pipe 6 for feeding material into the hopper cylinder 4 is provided on the baffle 2. The feed pipe 6 is connected to a feeding pump, and a control switch 7 is provided on the feed pipe 6. The control switch 7 includes a feeding control hydraulic press 71 installed on the feed pipe 6. A feed inlet 61 is provided on one side of the outer wall of the feed pipe 6, and a feeding hydraulic rod 72 is provided on the feeding control hydraulic press 71 to close the feed inlet 61. The feeding hydraulic rod 72 is movably installed inside the feed pipe 6. When feeding is required, the control switch 7 is first turned on, and then the material to be dehydrated can be pumped into the feed pipe 6 by the feeding pump, and the material to be dehydrated can then enter the hopper cylinder 4 through the feeding pipe 6.The present invention provides a honeycomb piston 8 inside the silo cylinder 4, and a secondary dewatering hydraulic mechanism 9 on the hydraulic cylinder support 3, which can drive the honeycomb piston 8 to move up and down. The secondary dewatering hydraulic mechanism 9 includes a secondary dewatering hydraulic press 91 fixedly mounted on the hydraulic cylinder support 3. An assembly hole is provided at the center of the bottom of the silo cylinder 4. The hydraulic rod 92 of the secondary dewatering hydraulic press 91 passes through the assembly hole and is connected to the honeycomb piston 8. A plurality of honeycomb holes 10 are provided inside the honeycomb piston 8. A hollow guide rod 11 is provided at the bottom of the silo cylinder 4 at a position corresponding to the honeycomb holes 10. The hollow guide rod 11 is disposed inside the honeycomb holes 10. Filter cloth (not shown in the figure) is covered on the surface of the honeycomb piston 8 and the surface of the hollow guide rod 11. A drain hole 12 is provided at the bottom of the silo cylinder 4.

[0042] The hollow guide rod 11 described in this invention is a spiral hollow guide rod, comprising a hollow rod body 111 with a closed upper end. A spiral guide groove 112 is provided on the outer wall of the hollow rod body 111, and a plurality of first water outlet holes 113 are provided within the spiral guide groove 112.

[0043] The method of using the vertical ultra-high pressure secondary dehydration honeycomb press integrated machine in Example 1: S1. First, start the auxiliary hydraulic press 51 to drive the auxiliary hydraulic rod 52 to move the hopper cylinder 4 upward, so that the upper end of the hopper cylinder 4 is pressed against the baffle 2. At this time, the hopper cylinder 4 and the baffle 2 are sealed to each other. S2. Start the secondary dewatering hydraulic press 91, drive the hydraulic rod 92 to move the honeycomb piston 8 down away from the position of the baffle 2, so that the capacity of the hopper cylinder 4 is maximized. Start the feeding control hydraulic press 71, drive the feeding hydraulic rod up, so that the feeding port 61 is opened. S3. Control the feeding pump to feed the material to be dehydrated into the hopper cylinder 4 from the feed inlet 61 and fill it with pressure. Use the pressure of the feeding pump to dehydrate the material for the first time. S4. When the pressure inside the silo cylinder 4 reaches the predetermined value, the feeding hydraulic rod is controlled to move downward by the feeding control hydraulic press 71 to close the feed port 61, ensuring that the material to be dehydrated will not flow back. S5. Start the secondary dewatering hydraulic press 91, so that the hydraulic rod 92 drives the honeycomb piston 8 to move upward, squeezing the material to be dewatered in the hopper cylinder 4, and performing secondary ultra-high pressure dewatering treatment. The filtrate flows into the bottom of the hopper cylinder 4 through the first water outlet 113 of the hollow guide rod 11, the first guide grid 81 on the honeycomb piston 8, and the second water outlet 23 of the baffle 2, and then is discharged through the drain hole 12.

[0044] S6. After pressing is completed, start the auxiliary hydraulic press 51 first, drive the auxiliary hydraulic rod 52 to move the hopper cylinder 4 and the hollow guide rod 11 downward. After all the filter cake is exposed from the hopper cylinder 4, start the secondary dewatering hydraulic press 91, drive the hydraulic rod 92 to move the honeycomb piston 8 and the filter cake to the unloading position, and unload the filter cake from the honeycomb piston 8.

[0045] Example 2 The difference between this embodiment and Embodiment 1 is that the hollow guide rod 11 is a mesh hollow guide rod, comprising a hollow rod body 111 with a closed upper end, and a mesh guide groove 114 provided on the outer wall of the hollow rod body 111, with a plurality of first water outlet holes 113 provided in the mesh guide groove 114. The mesh guide groove 114 allows the filtrate to enter the first water outlet holes 113 more smoothly.

[0046] Example 3 The difference between this embodiment and embodiment 1 or 2 is that, in this embodiment, the second guide grid 22 and the second water outlet 23 are not provided in the baffle 2, but rather a number of third water outlets 18 are provided on the honeycomb piston 8.

[0047] Example 4 See Figure 11-16This embodiment is based on Embodiment 3. The hollow guide rod 11 of this invention includes a hollow rod body 111, the lower end of which extends out of the bottom of the hopper cylinder 4. A vacuuming telescopic tube 16 is movably disposed inside the hollow rod body 111, and the lower end of the vacuuming telescopic tube 16 is fixedly disposed inside the gas collecting plate 14. The gas collecting plate 14 is connected to a vacuum device through a vacuuming pipe 15. The outer wall of the vacuuming telescopic tube 16 is dynamically sealed to the inner wall of the hollow rod body 111. A connecting ring platform 17 is provided on the hydraulic rod 92, and the bottom surface of the gas collecting plate 14 is fixedly disposed on the connecting ring platform 17. The upper end face of the vacuuming telescopic tube 16 is located between the lower end face and the upper end face of the honeycomb piston 8. That is, the upper end face of the vacuuming telescopic tube 16 is located inside the honeycomb holes 10. In this invention, a water outlet pipe is provided on the bottom surface of the gas collecting plate 14, and a switch is provided on the water outlet pipe. In this embodiment, a vacuum device can create negative pressure inside the gas collecting plate 14, allowing the filtrate to enter the third water outlet 18 more quickly and easily, effectively accelerating the filtration efficiency. After filtration is complete, the vacuum device is turned off, and the switch on the water outlet pipe is opened to discharge the filtrate from the gas collecting plate 14. In this invention, the vacuum telescopic tube 16 moves synchronously with the honeycomb piston 8 inside the hollow rod 111, effectively sealing the first water outlet 113 below the honeycomb piston 8, thus ensuring that the inside of the honeycomb piston 8 and the upper hollow rod 111 are always under negative pressure. The piston of this invention is made in a honeycomb shape, and the hollow guide rod is installed inside the honeycomb holes, forming a honeycomb hopper with the hopper cylinder 4. This effectively solves the problem of the filter cake center being difficult to dehydrate, greatly improving the dehydration rate, shortening the dehydration time, overcoming the difficulty of making thick filter cakes, and improving production efficiency.

[0048] Example 5 See Figure 17 and 18The difference between this embodiment and Embodiment 1 is that, in this embodiment, a first guide ring groove 201 and a second guide ring groove 202 are spaced apart on the lower end surface of the baffle 2. In this embodiment, the outer diameter of the first guide ring groove 201 is smaller than the inner diameter of the second guide ring groove 202. A filter cloth covers the lower end surface of the baffle 2. A plurality of second water outlet holes 23 are respectively provided in the first guide ring groove 201 and the second guide ring groove 202. A water collection plate 203 is provided above the baffle 2. The second water outlet holes 23 are connected to the water collection plate 203 through a water receiving pipe 204. A connecting pipe 205 communicating with the inner cavity of the water collection plate 203 is provided on the water collection plate 203. In this embodiment, when the honeycomb piston 8 moves upward to squeeze the material to be filtered, the filtrate enters the first guide ring groove 201 and the second guide ring groove 202 through the filter cloth, and then collects in the water collection plate 203 through the second water outlet holes 23 and the water receiving pipe 204, and then is discharged through the connecting pipe 205. In this invention, when it is necessary to clean the filter cloth on the baffle 2, clean water can be supplied to the connecting pipe 205. The water enters the first guide ring groove 201 and the second guide ring groove 202 through the connecting pipe 205, thereby backwashing the filter cloth.

[0049] Example 6 This embodiment combines the structure of Embodiment 4 with that of Embodiment 5. In the pressure filtration process, the filtrate can pass through the filter cloth on the baffle 2 and enter the second outlet 23. Simultaneously, it can pass through the filter cloth on the honeycomb piston 8, enter the third outlet 18, and then through the filter cloth on the hollow guide rod 11 to enter the first outlet 113. In this embodiment, a three-way valve can also be installed on the suction pipe 15, with a backwash pipe connected to one inlet. When backwashing is required on the filter cloth on the honeycomb piston 8 and the filter cloth on the hollow guide rod 11, clean water can be injected into the air collection plate 14 through the backwash pipe. The water will flow out from the first outlet 113 and into the honeycomb holes 10 of the honeycomb piston 8. Since the first outlet 113 below the honeycomb holes 10 is closed by the suction telescopic pipe 16, by controlling the upward movement of the honeycomb piston 8, the filter cloth on the hollow guide rod 11 can be gradually backwashed, thus effectively ensuring the cleaning water pressure. The backwashing effect is good.
