[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a washing and screening device for concrete waste slurry includes a washing tank 1, a conveying tank 2, and a vibrating screen 3.

[0017] like Figure 1 , Figure 2As shown, the washing tank 1 is open at the top. The upper side walls on both sides of the washing tank 1 are respectively connected to the water inlet pipe 11 and the screw conveyor 12, and the lower side wall is provided with the slurry outlet 13. The filter tank 14 is provided below the slurry outlet 13, and the filter tank 14 is lined with a sponge pad 15.

[0018] like Figure 1 , Figure 2 As shown, a filter plate 4 with an arc-shaped cross section is installed in the cleaning tank 1. The filter plate 4 is vertically slidably connected to the cleaning tank 1. Support frames 41 that abut against the bottom wall of the cleaning tank 1 are provided on both sides of the filter plate 4. A sealing plate 42 that blocks the screw conveyor 12 is installed on the support frame 41.

[0019] like Figure 1 , Figure 2 As shown, the cleaning tank 1 is equipped with a drive mechanism 5 for controlling the vertical sliding of the filter plate 4. The drive mechanism 5 includes a drive frame 51 and a cylinder 52. The drive frame 51 is located on the lower end face of the filter plate 4, and the cylinder 52 is located at the bottom of the cleaning tank 1 and is used to control the vertical sliding of the drive frame 51.

[0020] like Figure 1 , Figure 2 As shown, the drive frame 51 includes a base frame 53, a top frame 54, a motor 55, and a crank-connecting rod mechanism 56. The base frame 53 is connected to the cylinder 52, the top frame 54 is vertically slidably connected to the base frame 53, the motor 55 is mounted on the base frame 53, and the crank-connecting rod mechanism 56 is located between the motor 55 and the top frame 54.

[0021] like Figure 1 , Figure 3 As shown, the conveyor barrel 2 has a circular cross-section and is horizontally connected above the washing tank 1. The lower side wall of the conveyor barrel 2 is provided with a discharge port 21. The vibrating screen 3 is set on the ground and connected to the discharge port 21.

[0022] like Figure 3 As shown, a rotating shaft 22 is horizontally rotatably connected inside the transmission barrel 2. Multiple hollow transmission plates 23 are provided on the outer wall of the rotating shaft 22. The transmission plates 23 abut against the transmission barrel 2 and the filter plate 4. A shovel plate 24 is provided at the end of the transmission plate 23 away from the rotating shaft 22.

[0023] When concrete waste slurry needs to be treated, the screw conveyor 12 is used to transport the concrete waste slurry to the cleaning tank 1, and clean water is injected into the cleaning tank 1 through the water inlet pipe 11. Then, the motor 55 is controlled to rotate, and under the cooperation of the crank connecting rod mechanism 56, the top frame 54 is controlled to move vertically and reciprocally. At this time, the top frame 54 drives the filter plate 4 to move synchronously, realizing the vibration cleaning of the concrete waste slurry.

[0024] Then the motor 55 is turned off, and the cylinder 52 is used to control the base frame 53 and the top frame 54 to move upward synchronously. The top frame 54 drives the filter plate 4 to move upward and pushes the sand and gravel to move upward synchronously. At the same time, the sealing plate 42 on the support frame 41 is used to seal the screw conveyor 12.

[0025] At the same time, the slurry is discharged outward along the slurry outlet 13 and filtered again by the sponge pad 15 in the filter tank 14 to separate the clean water from the cement slurry, so that the clean water can be discharged directly.

[0026] Then, control the rotating shaft 22 to rotate, and the rotating shaft 22 drives the transmission plate 23 to move synchronously. Under the action of the shovel plate 24 on the transmission plate 23, the sand and gravel on the filter plate 4 are shoveled up until the filter plate 4 moves to the discharge port 21 position. Then, the sand and gravel slide down the discharge port 21 onto the vibrating screen 3 to realize the vibration screening of the sand and gravel.
