As shown in fig. 2, 5 and 4, a plurality of sand washing water pipes 3 are arranged in the vibrating screen box 15, the discharge port of the coarse filter element is provided with one sand washing water pipe 3, the sand washing water pipe 3 is provided with a row of water outlet pipes 10, the water outlet pipes 10 are inclined at 5-45 degrees in the vertical direction, the water outlets of the water outlet pipes 10 are inclined, the inclination direction is opposite to the discharge direction, the sand washing efficiency is improved, the blockage of sand and stone is reduced, and unnecessary water resource waste is avoided. 2-3 sand washing water pipes 3 are arranged on the fine filter element 202; the first sand washing water pipes 3 are respectively arranged on the discharge hopper 4, and the second sand washing water pipes 3 and the third sand washing water pipes 3 are respectively arranged at the 1/3 position and the 2/3 position of the vibrating screen box 15, which are far away from the discharge hopper 4. Or 1/2 department sets up one in the shale shaker case 15 the sand washing water pipe 3 set up one more on the sand washing water pipe 3 one row outlet pipe 10, sand washing water pipe direction with coarse filter sets up outlet pipe 10 direction is unanimous. Both setting methods can improve sand washing efficiency. Go up 2 ~ 3 sand washing water pipe 3 all is connected through a plurality of valves 301 with a main water pipe 5, and this way can be adjusted according to equipment sand washing work load size valve 301 comes controlgear water yield, can the rational utilization water resource, reduces water waste, reduces equipment working cost.

As shown in fig. 1, 2 and 3, the vibration box 15 is provided with a main feed pipe 6 and a cyclone 7. The main feed pipe 6 is above the vibrating box 15 and the cyclone 7 is located above the vibrating screen box 15 and close to the main feed pipe 6, in front of which the discharge of the cyclone 7 falls onto the filter assembly 2. The included angle range of the swirler 7 and the vertical direction is 0-45 degrees.

As shown in fig. 1, 2, 5 and 3, the mortar enters the cyclone 7 from the main feed pipe 6, and the centrifugal sedimentation principle is utilized. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone under a certain pressure, strong three-dimensional elliptical strong-rotation shearing turbulent motion is generated. Because the coarse particles and the fine particles have different particle size differences and are subjected to different magnitudes such as centrifugal force, centripetal buoyancy, fluid drag force and the like, under the action of centrifugal sedimentation, most of the coarse particles are discharged through a bottom flow port of the cyclone, and most of the fine particles are discharged into the vibrating screen box 15, so that most of the coarse particles and most of the fine particles are separated. When most of fine particles vibrate and separate sand on the filter component 2 in the vibrating screen box 15, the valve on the water outlet pipe 3 is opened, water is sprayed out from the water outlet pipe of the sand washing water pipe 3, and sand washing work is carried out on sand on the filter component 2.
