When the drilling cuttings reversely flowing from the surface of the retarding plate 3 fall onto the middle plate 11, the middle plate 11 is extruded, so that the middle plate 11 moves downwards, the supporting springs compress, the drilling cuttings falling onto the middle plate 11 gradually slide down, after the drilling cuttings no longer fall onto the upper side, the drilling cuttings on the middle plate 11 gradually decrease, at the moment, the supporting springs push the middle plate 11 to rise, the distance between the drilling cuttings subsequently sliding from the middle plate 11 and the drilling cuttings previously sliding down gradually increases, the drilling cuttings are prevented from accumulating, the contact effect between the leaching solution and the drilling cuttings is increased, and the desalting effect is improved.
Preferably, a plurality of groups of guide assemblies are fixedly connected to the top of the middle plate 11, each guide assembly comprises two guide plates 13, and the distance between the guide plates 13 gradually decreases towards the side close to the collecting device 9. The two guide plates 13 in the same guide assembly can block the drill cuttings, and as the distance between the guide plates 13 gradually decreases towards the side close to the collecting device 9, the amount of the drill cuttings sliding off the middle plate 11 is reduced, the whole time of the drill cuttings sliding off the middle plate 11 can be prolonged, and the accumulation of the drill cuttings is further prevented.

When the tilting end of the retarder plate 3 is pressed down, the drill cuttings fall onto the middle plate 11, rebound from the middle plate 11 and fall onto the umbrella cap 19, the umbrella cap 19 can play a role in dispersing the drill cuttings, so that the dispersing effect is further improved, the umbrella cap 19 can compress the return spring 20 due to the existence of the return spring 20, and when the return spring 20 is restored, the drill cuttings at the top of the umbrella cap 19 can be pushed to move upwards, so that the interval distance between the drill cuttings is increased, and the drill cuttings are prevented from being accumulated.
Preferably, the concave grooves 5 at the top of two adjacent retarder plates 3 are staggered in the front-rear direction, and rubber protrusions 21 are arranged at the bottom of the inner side of each concave groove 5. After the concave grooves 5 on the adjacent retarder plates 3 are arranged in a staggered manner, when the drill cuttings fall onto the next retarder plate 3 after being intercepted by the concave grooves 5 for the first time, the probability of being intercepted by the concave grooves 5 on the next retarder plate 3 can be obviously reduced, so that the times of intercepting each drill cuttings by the concave grooves 5 on a plurality of retarder plates 3 are the same, and the integral desalting effect of each drill cuttings is ensured.
In addition, the embodiment also discloses a desalination method of the shale gas water-based drilling cuttings leaching desalination device, which comprises the following steps:
step one: before use, the drill cuttings are mechanically crushed to ensure that the diameter of the drill cuttings is less than 2cm, then the processed drill cuttings are lifted to a storage box 8 through a spiral lifting machine, and then a discharging channel 10 is opened to ensure that the drill cuttings slide into a desalting tank 1;
step two: then drill cuttings sliding into the desalting tank 1 can slide down obliquely to the retarder plate 3, the spray pipe 6 is externally connected with a circulating pump, the leaching solution at the bottommost part of the desalting tank 1 is circularly pumped, and finally the leaching solution is sprayed out from the spray header 7 to carry out leaching desalting on the passed drill cuttings;
step three: then drill cuttings sequentially pass through each retarding plate 3, a part of drill cuttings can enter the concave grooves 5 until the concave grooves 5 are full of drill cuttings, and the retarding plates 3 at the concave grooves 5 at corresponding positions can be pressed down to enable the retarding plates 3 and the drill cuttings in the concave grooves 5 to be completely separated;
step four: then a large amount of drill cuttings are hit on the next retarder plate 3, so that one end of the next retarder plate 3, which is tilted upwards, deflects downwards, and therefore the drill cuttings slide reversely and then fall onto the middle plate 11 corresponding to the bottom;
step five: the drill cuttings falling onto the middle plate 11 pass through the guide plate 13, the umbrella cap 19 and the arc plate 17, so that the drill cuttings can be dispersed and then fall off from the surface of the stepped platform 2 in sequence;
step six: finally, the drill cuttings sliding off the surface of the retarding plate 3 and the drill cuttings sliding off the surface of the stepped platform 2 enter a collecting device 9, and the collecting device 9 brings the desalted drill cuttings out of the desalting tank 1 and pours the drill cuttings out to finish the desalting treatment of the drill cuttings.
Although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
