[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] like Figures 1 to 4 As shown, a concrete intelligent recycling sedimentation tank comprises a primary sedimentation tank 1, a secondary sedimentation tank 2 and a tertiary sedimentation tank 3. The primary sedimentation tank 1 and the secondary sedimentation tank 2 are connected through an overflow hole 4, and the secondary sedimentation tank 2 and the tertiary sedimentation tank 3 are connected through an overflow port 24. A concrete sedimentation tank 5 is also installed in the primary sedimentation tank 1. Four weighing mechanisms 6 are installed at the bottom of the concrete sedimentation tank 5. A lifting and vibration mechanism 7 is installed at the bottom of each weighing mechanism 6. The weighing mechanism 6 and the lifting and vibration mechanism 7 are respectively connected to a control room 8. The concrete sedimentation tank 5 is used to collect settled sludge; the weighing mechanism 6 is used to weigh the concrete sedimentation tank. When the weight reaches a set value, the control room controls the lifting and vibration mechanism to lift the sedimentation tank until it rises above the primary sedimentation tank, and controls the vibration of the concrete sedimentation tank to dump the sludge in the concrete sedimentation tank to the ground. The bottom surface of the secondary sedimentation tank is an inclined surface, and the side close to the overflow port is higher than the side away from the overflow port.

[0018] In the present invention, the primary sedimentation tank 1, the secondary sedimentation tank 2 and the tertiary sedimentation tank 3 are all made of concrete.

[0019] The primary sedimentation tank is connected to the secondary sedimentation tank through two overflow holes, and the overflow holes are located 50 cm away from the upper edge of the sedimentation tank. The secondary sedimentation tank 2 and the tertiary sedimentation tank 3 are connected through the overflow port 24, and the overflow port 24 is set at the top of the partition wall between the secondary sedimentation tank 2 and the tertiary sedimentation tank 3. The waste concrete separated from the sand and gravel separator of the concrete mixing station recovery system enters the primary sedimentation tank, and the waste concrete is deposited in the concrete deposition tank 5. When the weight of the deposited concrete reaches the set value, the lifting vibration mechanism lifts the concrete deposition tank, so that the waste concrete automatically slides to the recycling vehicle.

[0020] like Figure 5 As shown, the concrete sedimentation tank 5 is mainly composed of a bottom plate 19, a side plate 20, a back plate 21 and a movable plate 22. The side plates 20 are installed on both sides of the bottom plate 19, the back plate 21 is installed at the rear of the bottom plate 19, and the front end of the bottom plate 19 is hinged with a movable plate 22. There are gaps between the side plates 20, the back plate 21 and the wall of the primary sedimentation tank 1. There are multiple water-permeable holes 23 on the side plates 20 and the back plate 21. The movable plate 22 contacts the wall of the primary sedimentation tank 1, and when the concrete sedimentation tank rises above the primary sedimentation tank, the movable plate changes from a vertical state to a horizontal state. There is a gap between the concrete sedimentation tank and the primary sedimentation tank, so that the clarified liquid in the concrete sedimentation tank can enter the primary sedimentation tank through the water-permeable holes and the gap. At the same time, the movable plate of the concrete sedimentation tank is squeezed and closed by the wall of the primary sedimentation tank. When the concrete sedimentation tank rises above the primary sedimentation tank, the movable plate automatically opens, and the concrete in the concrete sedimentation tank automatically slides into the recovery vehicle.

[0021] like Figure 6 As shown, the weighing mechanism 6 is mainly composed of a weighing sensor 9 and a waterproof seat 10. The waterproof seat 10 is provided with a mounting groove 11. The waterproof seat 10 is provided with an annular connecting plate 12 on its circumference. The weighing sensor 9 is installed in the mounting groove 11. The weighing sensor 11 is close to the bottom of the concrete sedimentation tank 5. The annular connecting plate 12 is installed on the bottom of the concrete sedimentation tank 5 by bolts. A high-elastic annular sealing gasket 13 is installed between the annular connecting plate 12 and the concrete sedimentation tank 5. The lifting vibration mechanism 7 is mainly composed of a hydraulic cylinder 14 and a short spring 15. An upper spring column 16 is installed at the bottom of the waterproof seat 10. A lower support plate 17 is installed on the piston rod of the hydraulic cylinder 14. A lower spring column 18 is installed on the lower support plate 17. A short spring 15 is installed between the upper spring column 16 and the lower spring column 18.

[0022] The weighing mechanism and the lifting and vibrating mechanism are installed together. The weighing sensor of the weighing mechanism is installed in the waterproof seat. The weighing sensor contacts the concrete sedimentation tank and bears the weight. The annular connecting plate of the waterproof seat is used to make the weighing sensor close to the concrete sedimentation tank, and cooperate with the high-elastic annular sealing gasket to achieve circumferential sealing to ensure that the weighing sensor can work normally. The lifting and vibrating mechanism uses hydraulic cylinders and springs. There are four hydraulic cylinders, which are respectively set at the four corners of the concrete sedimentation tank. The spring is mainly to produce a certain amount of shaking when it is lifted, so as to facilitate the sliding of concrete. When in use, the four hydraulic cylinders are raised synchronously. When the concrete sedimentation tank is raised above the first-level sedimentation tank, the two hydraulic cylinders behind the concrete sedimentation tank continue to rise to form a 30° inclined surface on the bottom plate of the concrete sedimentation tank. At the same time, the hydraulic cylinders reciprocate to make the concrete sedimentation tank shake, thereby increasing the sliding speed of the waste concrete.

[0023] When in use, follow the steps below: waste concrete enters the primary sedimentation tank through the recovery system of the concrete mixing station, the clarified liquid enters the secondary sedimentation tank, the clarified liquid of the secondary sedimentation tank enters the tertiary sedimentation tank, and the clarified liquid of the tertiary sedimentation tank is recycled; the waste concrete is slowly deposited in the primary sedimentation tank, and the weighing mechanism weighs the weight of the waste concrete; when the weight reaches the set value, the control room controls the lifting and vibration mechanism to lift the concrete sedimentation tank until the concrete sedimentation tank is located above the primary sedimentation tank, and the concrete sedimentation tank is in an inclined state, so that the deposited waste concrete slides out of the concrete sedimentation tank and is recovered in the recycling vehicle.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
