Said socket 21 is inserted into the short tube 351 of the lowermost percolation module 35.
At least three supporting rods 323 are arranged around the short pipe 322 below the disc 321, so that the disc 321 is prevented from being deformed or broken due to the over-weight bearing.
The outermost layer of the percolation layer 332 in the horizontal cross section is provided with a mud-proof layer 333, and the mud-proof layer 333 can prevent a large amount of large-particle mud from blocking a subsequent filter material layer 334 quickly, and a small amount of small-particle mud and water from passing through the mud-proof layer 333.

The top 363 of the filtration module 36 at the uppermost part is sleeved with an inverted sealing sleeve 5, the lower end of the sealing sleeve 5 is open and the upper end of the sealing sleeve is sealed, the top of the sealing sleeve 5 is provided with a vent pipe 51, the vent pipe 51 is communicated with the water outlet cavities 352 and 362, and the vent pipe 51 is connected to a vacuum pump 52. This creates a vacuum in the effluent chamber 352, 362 when the vacuum pump 52 is turned on, and the pressure differential created by the atmospheric pressure and the vacuum accelerates the driving of the slurry water through the filtration module 35, 36 into the effluent chamber 352, 362 for discharge.
The working principle and the use of the invention are described below with an embodiment in which two percolation modules 35, 36 are connected in series:
After the raw slurry is fed from the drying basin 6, part of the water in the slurry below the slurry surface passes through the percolation modules 35, 36 under the action of gravity in the direction of the arrows in fig. 6. In this process, a large amount of large particle mud is blocked by the palm mat layers 354, 364 from the outside of the percolation modules 35, 36, avoiding a very fast clogging of the subsequent filter layers 355, 365, and a small amount of small particle mud and water passes through the palm mat layers 354, 364, the subsequent filter layers 355, 365 being able to effectively retain the small particle mud passing through the palm mat layers 354, 364. The filtrate passing through the filter material layers 355 and 365 passes through the through holes 356 and 366, passes through the water outlet cavities 352 and 362, flows down along the inner walls of the water outlet cavities 352 and 362 to the water conveying pipe 2, and the water conveying pipe 2 conveys the collected filtrate to the clean water basin 7.
When the slurry level rises to the designed maximum slurry level 8, vacuum pump 52 is turned on, which creates a vacuum in the effluent chamber 352, 362, and at this time, the pressure differential between the atmospheric pressure at the slurry level and the vacuum in the effluent chamber 352, 362 accelerates the driving of the water in the slurry through the filtration module 35, 36 into the effluent chamber 352, 362 to create a filtrate discharge. After the vacuum pump 52 is turned on for a period of time, little or no filtrate is drawn from the outlet chambers 352, 362 and the vacuum pump 52 is turned off. At the moment, the mud surface of the slurry is lowered to the position of a dried mud surface 9, and the dried mud surface 9 is higher than the lower end of the sealing sleeve 5. The slurry in the drying tank 6 is naturally dried for a period of time to meet the transportation requirement.
And drawing out the dry mud 61 reaching the standard, taking out each percolation module 3 intercepted with the granular mud, and cleaning. The filter screen I331 of the percolation module 3 is opened, the anti-mud layer 333 and each filter material layer 334 are taken out layer by layer, a water gun is used for taking water in the clean water tank 7 to wash the anti-mud layer 333 and each filter material layer 334, and the filter material layer is easy to clean quickly due to the fact that the relative thickness of each layer is not thick. When the filter material layer 334 leaks, the filter II 336 is opened to supplement the filter material 335 with the same grain size, and the filter II 336 is closed. The cleaned mud-proof layer 333 and the filter material layer 334 are returned to the infiltration layer 332, and the infiltration layer 332 is sleeved on the water outlet cavity 31 and is positioned on the supporting block 32 to form a clean infiltration module 3 for the next use.
The present invention is not limited to the embodiments described, and any equivalent substitutions and modifications that produce the same effects are included in the scope of the disclosure of the present invention. For example, although the percolation body 33 in the example is a hollow cylinder, the person skilled in the art may implement the invention in other forms, for example, where two percolation modules 3 are used in series, but it is also possible to use a single or more percolation modules 3 in series. Furthermore, the support block 32 is not limited to the embodiments mentioned in the examples of the invention, and other support means of equivalent substitution or obvious modification may be used by those skilled in the art.
