the gel breaking and destabilizing tank 1 is of a U-shaped structure, an inner and outer double-helix stirrer 4 is arranged in the gel breaking and destabilizing tank 1, the distance between a helical ribbon of the inner and outer double-helix stirrer 4 and the tank wall is 8mm, and the inner and outer double-helix stirrer 4 is connected with a driving device 2 at one end outside the gel breaking and destabilizing tank 1; a waste drilling mud feeding hole 7 is arranged in the middle of one side of the gel breaking and destabilizing tank 1 and 20cm higher than the highest point of the ribbon of the inner and outer double-helix stirrer 4; 2 medicine inlet pipe orifices of the gel breaking and destabilizing agent medicine inlet pipe 5 are arranged at the position which is 30cm higher than the highest point of the spiral ribbon of the inner and outer double-spiral stirrers 4 on the same side, the 2 medicine inlet pipe orifices are positioned at 3 equal segments of the U-shaped gel breaking and destabilizing tank 1, and the medicine inlet pipe orifices extend into the U-shaped gel breaking and destabilizing tank 1 for 20 cm; 2 flocculant medicine inlet pipe openings 6 are arranged on the parallel lines of the connecting lines of 2 medicine inlet pipe openings of the gel breaking and destabilizing medicine inlet pipe 5, close to the left side (or the right side), and extend into the U-shaped gel breaking and destabilizing tank 1 by 20 cm; the medicine inlet pipes of the 2 gel breaking and destabilizing agent medicine inlet pipes 5 and the medicine inlet pipes of the 2 flocculating agent medicine inlet pipes 6 are respectively connected with a three-way pipe in the middle of the outer side of the gel breaking and destabilizing tank 1, and the medicine inlet end of the three-way pipe is connected with a medicine adding metering pump; a rotary valve discharge port 8 is arranged at the middle position of the bottom of the gel breaking and destabilizing tank 1; the upper part of the gel breaking and destabilizing tank 1 is provided with a net cover 9, and the mesh is 10cm multiplied by 10 cm.

Wherein, the support frame 3 is arranged below the gel breaking and destabilizing tank 1, the height of the support frame is more than about 50cm of the height of the dehydrator, the support frame is used for supporting the gel breaking and destabilizing tank and the driving device, and the purpose of setting a certain height is that slurry after gel breaking and destabilizing directly falls into the solid-liquid dehydrator.

Wherein, discharge gate 8 inclines about 20 degrees angles, and the direction is towards the other side direction of broken glue destabilizing jar 1 feed end.
