[0036] The first filter screen 21 and the second filter screen 23 are used to block fine particles, the first filter hole 22 and the second filter hole 24 are used to discharge the fluid upward, the support rod 25 is used to support the second filter screen 23, the fixing plate 26 is used to support the fixing nut 27, and the fixing nut 27 is used to fix the support rod 25;

[0037] The sand removal and exhaust assembly also includes a support frame 12, a water inlet pipe 14 and a water outlet pipe 15;

[0038] The support frame 12 is fixedly connected to the outer surface of the cyclone desander 11, the water inlet pipe 14 is fixedly connected to the outer side of the upper end of the cyclone desander 11, the water outlet pipe 15 is fixedly connected to the central position of the top of the cyclone desander 11, and the sand discharge pipe 13 is fixedly connected to the bottom end of the cyclone desander 11;
