1. A high-stability shale gas desanding device with a gravel storage mechanism, comprising a shale gas desanding assembly, a driving assembly, a flow stirring assembly and a flow guide assembly, wherein the shale gas desanding assembly comprises an outer side gas-solid separation tank, an inner side gas-solid separation tank is sleeved inside the outer side gas-solid separation tank, the inner side gas-solid separation tank is communicated with a shale gas mixture ingress pipe of the flow guide assembly, a top portion of the shale gas desanding assembly is communicated with an interior of the outer side gas-solid separation tank through a first pressure balance pipe, the outer side gas-solid separation tank is communicated with the shale gas mixture ingress pipe through a second pressure balance pipe, a pressure regulation and control assembly is arranged on the second pressure balance pipe, the flow stirring assembly is further arranged inside the inner side gas-solid separation tank, and an input end of the flow stirring assembly is connected with an output end of the driving assembly; and
the inner side gas-solid separation tank and the outer side gas-solid separation tank are fixedly connected through a bridge-type connecting frame, and top portions of the outer side gas-solid separation tank and the inner side gas-solid separation tank are fixedly and hermetically connected with a same tank cover, an exhaust channel is clamped in the tank cover, a side end surface of the exhaust channel is clamped with the first pressure balance pipe, a second end of the first pressure balance pipe is clamped on a side end surface of the outer side gas-solid separation tank, and the first pressure balance pipe is further provided with a one-way valve;
wherein the driving assembly comprises a first support mesh panel, an arc surface of the first support mesh panel is fixedly connected with an inner side wall of the inner side gas-solid separation tank, a top portion of the first support mesh panel is clamped with a first bearing, a first adapter cylinder is sleeved in the first bearing, a first threaded cylinder is sleeved in the first adapter cylinder, a first threaded rod is threadedly connected on an internal thread surface of the first threaded cylinder, and a bottom portion of the first threaded rod is fixedly connected to a top portion of the first support mesh panel;
the flow stirring assembly comprises a connecting sleeve, the connecting sleeve is sleeved and fixed on a surface of the first threaded cylinder, an upper layer wheel disc and a lower layer wheel disc are sequentially fixed and connected on a circumferential surface of the connecting sleeve from top to bottom, and an arc connecting seat is slidably connected between the upper layer wheel disc and the lower layer wheel disc; and
a bottom portion of the arc connecting seat is provided with a second slidably connecting groove, a second slidably connecting seat is slidably connected in the second slidably connecting groove, an end surface inside the second slidably connecting groove is further fixedly connected with a side surface of the second slidably connecting seat through a first supporting spring, and a bottom portion of the second slidably connecting seat is fixedly connected to a top portion of the lower layer wheel disc.
