The external pump (hydraulic screw pump) 1 draws the mud in the on-site waste slurry tank to the coarse sieve layer 3 of the vibrating screen. After screening through the coarse sieve layer 3 of the vibrating sieve, the particles larger than 2 mm will be discharged, and the particles less than 2 mm will be discharged. Will enter the slurry tank 2, at this time the main slurry pump 8 pumps the mud in the slurry tank 2 to the cyclone 6, after the cyclone separation, most of the cleaned and separated standard slurry will be The overflow of the cyclone 6 flows out and enters the middle storage tank 7. The waste slag separated by the cyclone 6 is discharged through the bottom flow port, enters the vibrating screen fine sieve layer 4, and dewaters the waste residue through the sieve vibration. And eventually ruled out. The middle storage tank 7 is provided with two liquid outlets, one is a liquid replacement port at a position above the slurry storage tank 2, and the other is a position where the discharge port is located outside the connection between the slurry storage tank 2 and the intermediate storage tank 7; 10 is installed at the refill port of the intermediate tank 7, which can control the refilling amount of the accumulator 2 by the intermediate tank 7 by balancing the liquid level in the accumulating tank 2. When the reservoir 2 does not require the intermediate tank 7 to replenish water, the refill port of the intermediate tank 7 is closed by the internal circulation device 10. At this time, the discharge port of the intermediate tank 7 will be in a continuous slurry state. The recoil control valve 9 is connected to the main slurry pump through a three-way, and the three-way is connected through a pipeline, and is respectively connected to the cyclone 6 and the main slurry pump 8 and the slurry storage tank 2, and the function thereof is to utilize the surplus flow of the main pump. Stirring of the slurry in the reservoir 2 is achieved by the recoil control valve 9 to prevent mud from depositing in the apparatus.
