[0033] Working principle: The frame 1 is welded into a three-layer platform by using a first-layer bottom plate 11, a second-layer bottom plate 12, and a third-layer bottom plate 13. The whole set of mud treatment equipment is integrated on the equipment platform to form a compact modular mud treatment device, in which the mud delivery pump, purification tank, sand discharge trough, screw conveyor, etc. are arranged on the first-layer bottom plate 11. A rectangular mud purification tank design is adopted. The solid control sand discharge point is connected to the recovery system or the overboard according to the design requirements; the screen head box (distributor), vibrating screen, desander, desilter, degasser, etc. are arranged on the second-layer bottom plate. On the plate 12, a total of four vibrating screens are arranged, and a position for installing a vibrating screen is reserved. The third-party equipment such as the centrifuge is arranged on the top of the third-layer bottom plate 13. The entire frame 1 adopts a frame open structure design, which is convenient for ventilation and reduces the pressure of the ventilation system design. In the routine maintenance of the mud processing equipment, the user can use the auxiliary ladder 2 on the side of the frame 1 to climb up to the second-layer bottom plate 12 and the third-layer bottom plate 13 respectively, thus meeting the actual application needs; and when the anti-slip pad 32 on the pedal 22 is excessively worn and needs to be replaced, push the movable rod 31 upwards, This creates a gap between the stop block 35 on the movable rod 31 and the pedal 22, and then the movable rod 31 is rotated. Since the square rod 37 fixed on the movable rod 31 is slidably connected with the transmission shaft 38, the transmission shaft 38 can rotate together with the movable rod 31, and under the transmission of the first pulley group 39, the auxiliary shaft 312 and the screw rod 33 fixed on the auxiliary shaft 312 are driven to rotate together, and the pressure plate 34 threadedly connected to the screw rod 33 slides on the column 21 synchronously, so that the pressure plate 34 gradually moves away from the anti-skid pad 32, releasing the anti-skid pad. The anti-skid pad 32 is limited, and the anti-skid pad 32 can be replaced at this time. Then, the movable rod 31 is rotated in the opposite direction, so that the pressure plate 34 clamps and fixes the anti-skid pad 32 on the pedal 22 again. The movable rod 31 is released, and under the elastic force of the return spring 36 fixedly connected to the transmission shaft 38 and the stop block 35 at both ends, the gap between the stop block 35 and the pedal 22 is eliminated, so that the friction pattern on the bottom surface of the stop block 35 is in close contact with the pedal 22 and forms a certain friction force, so as to limit the rotation of the movable rod 31 and lock the clamping state of the pressure plate 34 against the anti-skid pad 32.When the anti-skid pads 32 on multiple pedals 22 need to be replaced, the threaded rod 41 threadedly connected to the column 21 is rotated. Because the end of the threaded rod 41 is rotatably connected to the trapezoidal block 411 using the third bearing 410, after the threaded rod 41 is rotated, the trapezoidal block 411 can be driven to slide inside the column 21, and then the inclined surface of the trapezoidal block 411 is used to push the slide bar 44 to slide upward. The slide bar 44 is provided with a sliding groove for accommodating the extension rod 313, and the extension rod 313 is fixedly connected to the slide plate 310, so the slide plate 310 can slide upward with the slide bar 44, and the slide plate 310 is rotatably connected to the stop block 35 using the first bearing 311. The stop block 35 slides synchronously at this time, and a gap is generated between the pedal 22 again, and the extension plate 46 fixed on the slide bar 44 is rotatably connected to the connecting rod 45 using the second bearing 48, and the friction block 47 is set between the two T-shaped shafts 42 The connecting rod 45 is fixedly connected to the connecting rod 45, and the connecting rod 45 is also slidably connected to one of the T-shaped shafts 42 by using the convex strips 49 on its surface. After the sliding rod 44 slides upward, the friction pattern on the upper surface of the friction block 47 is in close contact with the end surface of the T-shaped shaft 42 at its top, and when the extension plate 46 slides with the sliding rod 44, the remaining slide plates 310 are all located above the extension plate 46. After the extension plate 46 slides upward, the slide plates 310 can be pushed to slide upward together. At this time, the stop blocks 35 inside the multiple pedals 22 are together with the side wall of the inner cavity of the pedal 22. The two T-shaped shafts 42 are connected by the connecting rod 45 and the friction block 47, and the T-shaped shaft 42 and the auxiliary shaft 312 are connected by the second pulley group 43. At this time, after the single movable rod 31 rotates, the multiple screw rods 33 on the column 21 can rotate at the same time. At this time, the restrictions on the anti-skid pad 32 can be released at the same time, and the anti-skid pad 32 can be quickly replaced. ;
