Therefore, a gravel slurry solidification treatment device that can efficiently process gravel slurry, prevent gravel particle clogging, improve filtration efficiency, and reduce equipment maintenance costs is particularly important.

[0025] The present invention will be further described below with reference to the accompanying drawings.
[0026] like Figure 1-5 As shown, a crushed stone slurry solidification treatment device includes a frame 1, a filtering mechanism 2, an extrusion mechanism 3, and a control system 4. The filtering mechanism 2, the extrusion mechanism 3, and the control system 4 are located on the frame 1. A feeding mechanism 5 is provided on one side of the frame 1. The feeding mechanism 5 includes a feeding pump 6, a feeding pipe 7, and a pre-screening device 8. A flow control valve 9 and a pressure sensor 10 are provided on the feeding pipe 7. The flow control valve 9 is used to adjust the feeding flow rate, and the pressure sensor 10 is used to monitor the feeding pressure in real time and transmit the pressure signal to the control system 4. The pre-screening device 8 is located at the front end of the feeding pipe 7. The pre-screening device 8 includes a screening box 11 and a vibrating motor 12. The screening box 11 is provided with multiple layers of screens with different apertures. The vibrating motor 12 drives the screens to vibrate, so that the crushed stone slurry is screened in the screening box 11.
[0027] Furthermore, a first screen 13 and a second screen 14 are movably installed inside the screening box 11. The first screen 13 is located above the second screen 14, and the aperture of the first screen 13 is larger than the aperture of the second screen 14.
[0028] In this embodiment, the arrangement of the first screen 13 and the second screen 14 enables multi-stage screening of the crushed stone slurry. Large particles of crushed stone and impurities are retained by the first screen 13, while smaller particles pass through the first screen 13 and fall onto the second screen 14 for further screening. This multi-stage screening method improves screening efficiency, enabling effective separation of particles of different sizes in the crushed stone slurry and providing better conditions for subsequent processing steps.
[0029] Furthermore, a first stone outlet 15 and a second stone outlet 16 are provided on one side of the screening box 11. A connecting plate 17 is fixedly provided on one side of the first stone outlet 15 and the second stone outlet 16 inside the screening box 11. A collection box 18 is placed at the bottom of the first stone outlet 15 and the second stone outlet 16.
[0030] In this embodiment, the placement of the collection box 18 allows for convenient collection and storage of the screened gravel particles, facilitating subsequent processing and utilization.
[0031] Furthermore, one side of the first screen 13 and the second screen 14 is movably connected to the connecting plate 17 via a rotating shaft, and the other side of the first screen 13 and the second screen 14 is movably connected to a vibrating rod 19, one end of which is connected to the vibrating motor 12 for transmission.
[0032] Furthermore, the vibrating motor 12 is provided with an eccentric wheel 20, and a transmission rod 21 is movably mounted on the eccentric wheel 20. One end of the transmission rod 21 is connected to the vibrating rod 19 through a rotating shaft. A slide block 22 is fixedly installed on the outer wall of the screening box 11. One end of the vibrating rod 19 is inserted into the slide block 22, and the vibrating rod 19 is slidably connected to the slide block 22.
[0033] In this embodiment, the vibrating motor 12, through the transmission action of the eccentric wheel 20 and the transmission rod 21, causes the vibrating rod 19 to reciprocate. This vibration design not only enhances the screening effect of the screen, but also helps to prevent screen clogging, ensuring the continuity and stability of the screening process.
[0034] Furthermore, the first screen 13 and the second screen 14 are provided with a sliding groove 23 at the position where they are connected to the vibrating rod 19, and a sliding shaft 24 is movably installed in the sliding groove 23, and the vibrating rod 19 and the sliding shaft 24 are rotatably connected.
[0035] In this embodiment, the sliding shaft 24 is movably connected within the sliding groove 23, allowing the screen to have a certain degree of freedom when subjected to vibration, thereby better adapting to gravel and slurry of different particle sizes and improving the flexibility and adaptability of screening.
[0036] Furthermore, the bottom of the screening box 11 is configured as a funnel shape, the feed pump 6 is located at the bottom of the screening box 11, and the feed pump 6 is connected to the feed pipe 7.
[0037] Furthermore, the extrusion mechanism 3 includes a hydraulic cylinder 25 and an extrusion plate 26. The hydraulic cylinder 25 is installed on one side of the frame 1, and the piston rod of the hydraulic cylinder 25 is connected to the extrusion plate 26.
[0038] In this embodiment, during the filter press process, when the slurry in the filter chamber reaches a certain amount, the hydraulic cylinder 25 pushes the extrusion plate 26 to move towards the filter plate, extruding the slurry in the filter chamber to further improve the solidification effect of the slurry and reduce the moisture content of the slurry cake.
[0039] Furthermore, the control system 4 adopts a PLC controller 27, and the control system 4 is connected to the sensors and actuators of each component of the feeding mechanism 5 and the extrusion mechanism 3.
[0040] In this embodiment, the control system 4 can automatically control the start and stop of the feed pump 6, the adjustment of the feed flow rate, and the extension and retraction of the hydraulic cylinder 25 according to the preset program and the signals fed back by the sensor.
[0041] Furthermore, the filtration mechanism 2 includes multiple filter plates 28 and filter cloth. The filter plates 28 are rectangular and are arranged in parallel on the frame 1, forming a filtration chamber between adjacent filter plates 28.
[0042] In this embodiment, a filter cloth covers the surface of the filter plate 28 to intercept solid particles in the slurry and achieve solid-liquid separation. The filter plate 28 is provided with a feed hole, a filtrate discharge hole and a high-pressure water flushing hole. The feed hole is connected to the feeding mechanism 5 and is used to introduce the crushed stone slurry into the filtration chamber. The filtrate discharge hole is connected to the filtrate collection pipe and is used to discharge the filtered liquid.
[0043] The working principle of this utility model is as follows:
[0044] In use, the crushed stone slurry first enters the pre-screening device 8. The multi-layered screens in the pre-screening device 8 vibrate under the drive of the vibrating motor 12, performing preliminary screening of the crushed stone slurry. Larger particles of crushed stone pass through the first screen 13 and fall into the collection box 18 below the first stone discharge port 15, while smaller particles of crushed stone and slurry continue to pass through the second screen 14 and finally fall to the bottom of the screening box 11. The screened slurry is then fed into the filter chamber of the filter mechanism 2 by the feed pump 6. Inside the filter chamber, solid particles in the slurry are intercepted by the filter cloth, while the filtrate is discharged through the filtrate discharge hole. When the slurry in the filter chamber reaches a certain amount, the control system 4 controls the hydraulic cylinder 25 to push the extrusion plate 26 towards the filter plate, extruding the slurry and further improving its solidification effect. After extrusion, the control system 4 controls the high-pressure water flushing system to flush the filter cloth, removing any remaining solid particles.
