[0019] like Figures 1 to 3 As shown,
[0020] A concrete sand and gravel recovery equipment, characterized in that it includes a frame 2, a mixing drum 3 is fixedly connected to the upper end of the frame 2, a feeding pipe 4 is provided at the upper end of the mixing drum 3, a discharging pipe 5 is provided at the lower end of the mixing drum 3, a water collecting tank 6 is fixedly connected to the lower end of the frame 2, a fine sand collecting bin 7 is fixedly connected to one side of the water collecting tank 6, a gravel collecting bin 8 is fixedly connected to the other side of the water collecting tank 6, a first filter screen 9 is rotatably connected in the mixing drum 3, a first driving motor 10 is provided on the mixing drum 3 to drive the first filter screen 9 to rotate, a fine sand recovery component is provided on the fine sand collection bin 7, and a gravel recovery component is provided on the gravel collection bin 8.
[0021] In this embodiment, the wastewater after flushing the mixing equipment is sent from the feed pipe 4 to the mixing drum 3, the first filter screen 9 intercepts the gravel in the wastewater, the fine sand and wastewater pass through the first filter screen 9 and the discharge pipe 5, and fall on the fine sand recovery component, the fine sand recovery component recovers the fine sand into the fine sand collection bin 7, and the wastewater falls into the sump 6 below. When the wastewater is filtered, the first drive motor 10 drives the first filter screen 9 to rotate back and forth, so that the gravel intercepted on the first filter screen 9 rolls back and forth, and the fine sand stuck on the gravel is shaken off, while preventing the gravel from clogging the first filter screen 9. After the first filter screen 9 has been filtered for a period of time, the first drive motor 10 drives the first filter screen 9 to rotate to a vertical state, so that the gravel on the first filter screen 9 falls down, passes through the discharge pipe 5 and is recovered by the gravel recovery component.
[0022] In this embodiment, the fine sand recovery assembly includes a first rotating rod 11, which is rotatably connected to the fine sand collection bin 7, and a second filter screen 12 is fixedly connected to the first rotating rod 11. The fine sand collection bin 7 is provided with a second drive motor 13 for driving the first rotating rod 11 to rotate, and the second filter screen 12 can rotate to the bottom of the discharge pipe 5. The fine sand and water falling from the discharge pipe 5 fall onto the second filter screen 12, and the second filter screen 12 intercepts the fine sand, while the waste water passes through the second filter screen 12 and falls into the water collection tank 6. After a period of use, the second drive motor 13 drives the first rotating rod 11 to rotate, so that the second filter screen 12 rotates into the fine sand recovery bin, and the fine sand intercepted on the surface of the second filter screen 12 is poured into the fine sand collection bin, thereby realizing the automatic collection of fine sand.
[0023] In this embodiment, the gravel recovery assembly includes a second rotating rod 14, which is rotatably connected to the gravel collection bin 8, and a guide plate 15 is fixedly connected to the second rotating rod 14. The gravel collection bin 8 is provided with a third drive motor 16 that drives the second rotating rod 14 to rotate, and the guide plate 15 can rotate to the bottom of the discharge pipe 5. When the second filter screen 12 pours fine sand, the third drive motor 16 drives the second rotating rod 14 to rotate, so that the guide plate 15 rotates to the bottom of the discharge pipe 5. At this time, the first drive motor 10 drives the first filter screen 9 to rotate to a vertical state, so that the gravel on the first filter screen 9 falls down, and after the gravel falls on the guide plate 15, it slides along the guide plate 15 into the gravel collection bin 8, realizing automatic collection of the gravel.
[0024] In this embodiment, abutment block 17 is fixedly connected in the fine sand collection bin 7, and when the second filter screen 12 rotates, the end of the second filter screen 12 can abut against the abutment block 17. When the fine sand on the surface of the second filter screen 12 is poured into the fine sand collection bin 7, the end of the second filter screen 12 collides with the abutment block 17, and the fine sand on the filter screen is shaken off, thereby reducing the fine sand remaining on the surface of the second filter screen 12.
[0025] In this embodiment, abutment rod 18 is fixedly connected inside the mixing drum 3, and when the first filter screen 9 rotates, the first filter screen 9 can abut against the abutment rod 18. When the first filter screen 9 rotates back and forth, the first filter screen 9 can collide with the abutment rod 18, intensifying the vibration of the gravel on the first filter screen 9, making the separation effect of the gravel and fine sand better, and preventing the gravel from clogging the first filter screen 9.
[0026] In this embodiment, a drain pipe 19 is provided at the lower end of the water collecting pool 6 .
