The separation method of the soil-rock separation device by recycling the gravel-doped clay comprises the following steps:

step one, pouring gravel-doped clay fragments and clean water into a rotating component 5, and specifically comprises the following steps:

(1) Crushing the gravel-doped clay blocks and artificially primary screening: the combination of 5KG tup and 200mm long steel nail is utilized, the steel nail is stabilized above the gap or weak position of the gravel-doped clay by hand, the steel nail is driven into the gravel-doped clay by the tup, and the steel nail is shaken to loosen the gravel-doped clay structure. The loosened gravel-doped clay blocks are taken down, and are manually screened to screen a part of gravel with larger particle size and convenient for picking and separating, so that the situation that the hollow blade paddle is blocked in the rotating assembly when the lengthened rotating rod drives the hollow blade paddle to rotate can be effectively prevented.

The pore size specification of a conventional gravel screen set: 0.075mm, 0.15mm, 0.3mm, 0.6mm, 1.18mm, 2.36mm, 4.75mm, 9.5mm, 13.2mm, 16mm, 19mm, 26.5mm, 31.5mm, 37.5mm, 53.5mm. When some gravels with overlarge grain sizes are selected in the artificial primary screening, all gravels with the grain sizes of 53mm, 37.5mm and 31.5mm and a part of gravels with the grain sizes of 19mm and 16mm can be screened out basically.

(2) Adding gravel-doped clay fragments and clean water according to the volume of the rotating component 5: assuming that the volume of the rotating component 5 is V, the height is H and the radius of the bottom is R, gravel-doped clay is firstly added into the rotating component 5, and the added height is about 1/3H; and adding clear water into the rotating component 5 to enable the height of the mixture of the gravel-doped clay and the clear water to reach about 2/3 to 3/4H. Then, a rotating buckle 5-4 on the rotating component 5 is connected with a buckle on the 360-degree rotating rod 3, and the rotating component 5 is further fixed.

The order of placing the gravel-laden clay pieces and clean water into the swirling assembly 5 cannot be reversed. The gravel-doped clay blocks and the clear water should be put in advance, and if the clear water and the gravel-doped clay are put in advance, clay turbid liquid formed by dissolving the gravel-doped clay in the rotating group can splash.

Step two, starting the telescopic inner rod to rotate so as to drive the hollow blade paddle to fully rotate the gravel-doped clay and clear water: the gravel-doped clay in the initial rotation component 5 is faster and larger, and the direct use of the high-speed gear will cause the phenomena of unsmooth rotation and even splashing of clay suspension. Therefore, the lowest-grade rotation is selected firstly, so that the air in the clay is fully discharged when the larger gravel-doped clay is dissolved in water, and the clear water is fully immersed in the clay to form suspension preliminarily. After suspension is formed preliminarily, the liquid level of the mixture of the gravel-doped clay and the clear water is lowered by a certain height due to the discharge of air in the clay, so that the rotation speed of the hollow blade paddle 1-1 is further improved.

The telescopic inner rod 1-2 is firstly rotated by the lowest level 1 (the rotating speed is about 183 r/min), after the liquid level is stable, the rotating speed is increased to level 2 (the rotating speed is about 366 r/min) and rotated for 5min, and then the rotating speed is sequentially increased to level 3 (the rotating speed is about 549 r/min) and level 4 (the rotating speed is about 732 r/min) and respectively rotated for 5min. Only when the rotating speed of the hollow blade paddle 1-1 is gradually increased, the clay attached to the gravel can be fully dissolved in water, and a small amount of micro bubbles can float out of the liquid level at the moment. The telescopic inner rod 1-2 rotates to the liquid level and stops after no bubbles exist, if bubbles still exist, the rotating time of the hollow blade paddle 1-1 at the rotating speed level 4 (about the rotating speed 732 r/min) is properly prolonged.

In the initial stage of starting the telescopic inner rod 1-2, in order to enable clay in the gravel-doped clay block to be fully contacted with clear water to form turbid liquid, the telescopic inner rod 1-2 can be controlled to ascend or descend, so that the hollow blade paddle 1-1 is driven to ascend or descend, and the gravel-doped clay rotates at the maximum efficiency. However, the suspension is prevented from splashing due to too high rising and too high rotating speed.

Step three, moving the rotating component 5 into the screening and vibrating component 6, and carrying out screening and vibrating specifically comprises the following steps:

(1) And loosening the rotating buckle and the buckle on the 360-degree rotating rod: since the rotating assembly 5 is fixedly connected with the fixed outer rod 1-3 of the variable length rotating rod 1, in order to rotate the rotating assembly 5 above the screen vibrating assembly 6, the rotating buckles 5-4 and the 360-degree rotating rod 3 need to be loosened.

(2) And a lifting rotating component 5: the lifting rod 2 is lifted, and the fixed outer rods 1-3 on the variable-length rotating rod 1 and the rotating component 5 connected to the fixed outer rods 1-3 are driven to lift together. The height H 'and bottom radius R' of the screen assembly 6 are greater than the height H and bottom radius R of the spinner assembly 5, respectively. Therefore, the height of the rotation component 5 is ensured to be larger than H', so that the bottom of the rotation component 5 is not blocked by the screen vibration component 6 and can smoothly rotate to the area above the screen vibration component 6.

Step four, placing screen combination of gravel gradation with different apertures: and loosening the buckles 6-7 of the screen vibration and the buckles on the 360-degree rotating rod 3, and connecting the screen vibration assembly 6 with the flexible flange of the screen vibration base 8 through screw holes. Opening a safety buckle for preventing the double-opening door 6-2 from being opened in the screening vibration process, and opening the double-opening door 6-2; and (3) placing the screen combination of gravel grading with different required apertures in a multistage screen clamping groove 6-5 from top to bottom according to the aperture from large to small, closing the double-opening screen 6-2, and closing the buckles on the double-opening screen 6-2.

The multistage screen cloth clamping grooves are preferably eight stages, namely eight screen cloths with different grain diameters can be placed in the multistage screen cloth clamping grooves, and gravel with different hole diameters required by different tests can be met to the greatest extent.

Step five, rotating the rotating component 5 to the position above the screening and vibrating component 6: because the rotating component 5, the screen vibration base 8 and the warm air component 7 are respectively three vertexes of an equilateral triangle taking the lifting rod as a core, the rotating component 5 needs to be controlled to rotate 120 degrees along the length-variable rotating rod 1 to rotate above the screen vibration component 6. The rotating component 5 is opened to open more safety buckles on the door 5-2, so that the gravel-doped clay and clear water mixture in the rotating component 5 can fall into the screening and vibrating component 6 conveniently.

When the rotating component 5 is rotated to the position above the screen vibrating component 6 by opening the buckle on the multiple-opening shutter 5-2 in the rotating component 5, the lifting rod can be controlled to drive the rotating component 5 to slightly descend, so that a part of the bottom of the rotating component 5 enters the screen vibrating component 6. This is favorable to gravel and clay smooth entering sieve subassembly 6 inside.

Step six, putting the mixture into the screening and vibrating assembly 6: controlling the rotating component 5 to open more than the opening door 5-2 to open a small gap of about L1cm, firstly, allowing suspension, mud-like substances and small-sized gravels in the mixture of the gravel-doped clay and the clear water to fall into the screening and vibrating component 6, and keeping for 300s; then continue to open to a gap of about L2cm, where L2> L1, and let further larger gravel particles fall into the screen vibrating assembly 6 for 250s, and finally open to different sized gaps in sequence, such as L3cm, L4cm, L5 cm.

The purpose of slowly opening the multi-opening door 5-2 is to enable the mixture of gravel-mixed clay and clean water to slowly fall into the screen vibration assembly 6, so that the situation that suspension and gravel are splashed out is avoided.

Step seven, screening, discharging sludge and then screening and vibrating, which specifically comprises the following steps:

(1) And opening the screen vibration base 8 to perform preliminary screen vibration: and opening the screen vibration base to screen and vibrate the gravels and the turbid liquid in the screen vibration assembly 6, and further separating the gravels from the clay attached to the gravels. The vibration frequency was increased from low to high (level 1:37 times/min; level 2:74 times/min; level 3:111 times/min; level 4:148 times/min), and the maximum vibration frequency at which the suspension and gravel screen would not be shaken out was selected: if the gravel and suspension mixture in the swirling assembly 5 is completely released into the screen vibration assembly 6 and the liquid level does not reach or only reaches 2/3H ', the level 4 frequency screen vibration can be used, and if the liquid level exceeds 2/3H', the proper screen vibration frequency needs to be selected according to the situation.

(2) The mud discharging valve on the screen vibration assembly 6 is opened, and separated suspension is discharged: a container similar to a stainless steel barrel is used for containing the clay suspension.

(3) And opening the sieving vibration base 8 to sieve and vibrate the remaining gravels with different grain diameters again, wherein the gravel in the sieving vibration assembly 6 can not be ensured to fall on the drying net with the required grain diameter due to the sieving vibration in the suspension. After clay turbid liquid is discharged, the mud discharge valve 6-4 is kept open, the sieving vibration base 8 is started again, the wet gravel is sieved and vibrated, and the residual turbid liquid on the gravel can be vibrated out and discharged into the stainless steel barrel through the mud discharge valve 6-4. And the double-opening screen door is opened to take out the screen vibrating bottom plate at the bottom of the screen vibrating component 6.

Step eight, drying and storing the suspension after standing: the container filled with the clay suspension is left aside for 1 day. After 1 day of stewing clay can take place the precipitation of certain degree, one deck clear water layer can appear in clay turbid liquid top this moment, skims the clear water layer on upper strata with the water ladle, can reduce the stoving time on the one hand, and the clear water that on the other hand was skimmed out can be used when rotating separation mix the gravel clay piece next time. And pouring the left thick clay solution into the drying pan, and ensuring that the height of the thick clay solution in the drying pan is about 3cm, otherwise, the problem of difficulty in drying is caused due to too high height. And (5) placing the baking pans into the baking oven layer by layer for drying. Setting the temperature of the oven to be 105 degrees, and baking for 36 hours to obtain the dry clay without moisture.

The clay board after the stoving can strike through the simple striking of tup, breaks into the garrulous clay piece that the diameter is less than 2cm, is convenient for grind through grinding the machine, can supply experimental recycling next time.

Step nine, drying and screening gravels with different particle sizes again: opening a flexible flange connection of a screen vibration assembly 6 and a screen vibration base 8, controlling a 360-degree rotary rod 3 to drive the screen vibration assembly 6 to rotate 120 degrees to the position above a warm air assembly 7, firstly opening a 8level 1 weak wind shield of the warm air assembly, pre-drying gravel to a certain degree, removing redundant surface moisture, preventing excessive moisture from being blown out of an opening above the screen vibration assembly 6 by the warm air below, and setting the temperature of the level 1 weak wind shield to be 105 degrees and maintaining for 10 minutes; gradually and sequentially increasing the wind speed gears to level 4, wherein the interval between each gear is 10 minutes, and then maintaining a level 4 strong wind shield until all gravels are dried.

The hot air assembly 7 dries gravel in the screen vibration assembly 6 in a step-by-step enhancing mode, and each level of wind speed is divided into corresponding powers: 550 W, 850W, 1000W and 1200W. The blowing temperature can be set to 0-300 deg.

After the warm air assembly 7 is used for multiple times, redundant moisture and soil particles in the screen vibration assembly 6 can be accumulated in the warm air cavity, the warm air shell can be detached by detaching screws on screw holes of the warm air assembly 7, and the warm air shell is cleaned and then is connected with other structures of the warm air assembly 7.
