[0026] Figure 1 and Figure 2An embodiment of the sand and gravel washing system of this utility model is shown. The sand and gravel washing system of this embodiment includes a sand and gravel supply device 1, a first sand and gravel conveying mechanism 2, a sand and gravel dewatering device 3, and a second sand and gravel conveying mechanism 4 connected in sequence. The first sand and gravel conveying mechanism 2 is provided with a spraying mechanism 5 for spraying sand and gravel. The sand and gravel dewatering device 3 is connected to a wastewater recovery device 6. A receiving station 7 is provided below the discharge end of the second sand and gravel conveying mechanism 4.

[0027] Sand and gravel washing process: Sand and gravel supply device 1 supplies sand and gravel to first sand and gravel conveying mechanism 2, which then conveys the sand and gravel. When first sand and gravel conveying mechanism 2 passes through spraying mechanism 5, spraying mechanism 5 sprays and washes the sand and gravel on first sand and gravel conveying mechanism 2. After spraying and washing, the sand and gravel enter sand and gravel dewatering device 3 from the discharge end of first sand and gravel conveying mechanism 2. After being dewatered by sand and gravel dewatering device 3, the sand and gravel enter the feed end of second sand and gravel conveying mechanism 4, and then fall to the receiving station 7 below through the discharge end of second sand and gravel conveying mechanism 4. This sand and gravel washing system, on the one hand, continuously conveys sand and gravel throughout the process, improving production efficiency; on the other hand, the overall layout is reasonable, occupies little space, and has low cost.

[0028] Furthermore, in this embodiment, the sand and gravel dewatering device 3 is a vibration dewatering device.

[0029] Furthermore, such as Figure 2 As shown, in this embodiment, the sand and gravel dewatering device 3 includes a vibration mechanism 31 and a support 32 mounted on the vibration mechanism 31. A mesh belt conveyor 33 is mounted on the support 32 and is connected between the first sand and gravel conveying mechanism 2 and the second sand and gravel conveying mechanism 4. A water receiving trough 34 is located below the mesh belt conveyor 33 on the support 32, and the water receiving trough 34 is connected to a wastewater recovery device 6. Sand and gravel enter the feed end of the mesh belt conveyor 33 from the discharge end of the first sand and gravel conveying mechanism 2, are then conveyed by the mesh belt conveyor 33 to the discharge end, and finally enter the feed end of the second sand and gravel conveying mechanism 4 through the discharge end. During the process of conveying sand and gravel by the mesh belt conveyor 33, the vibration mechanism 31 vibrates, and the vibration of the mesh belt conveyor 33 is driven by the support 32, thereby accelerating the dewatering of the sand and gravel. In other words, the mesh belt conveyor 33 has both conveying and vibration dewatering effects on the sand and gravel.

[0030] The vibration mechanism 31 can be any conventional mechanism with vibration function. The vibration mechanism 31 can be mounted on the support 32 to drive the support 32 to vibrate. Alternatively, the support 32 can be mounted on the vibration mechanism 31 and vibrate with the vibration mechanism 31.

[0031] Furthermore, in this embodiment, the feed end of the mesh belt conveyor 33 is located below the discharge end of the first sand and gravel conveyor 2, so that the sand and gravel at the discharge end of the first sand and gravel conveyor 2 can fall directly to the feed end of the mesh belt conveyor 33.

[0032] Further, in the embodiment, the support 32 is provided with an outer cover 35 outside the mesh belt conveying mechanism 33. The outer cover 35 is provided with an inlet 351 above the inlet end of the mesh belt conveying mechanism 33. The outlet end of the first gravel conveying mechanism 2 is connected to the inlet 351. The outer cover 35 is also provided with an outlet 352. The outlet 352 is provided with a guide groove 353. One end of the guide groove 353 is located below the outlet end of the mesh belt conveying mechanism 33, and the other end is located above the inlet end of the second gravel conveying mechanism 4. The gravel at the outlet end of the first gravel conveying mechanism 2 falls through the inlet 351 to the inlet end of the mesh belt conveying mechanism 33. One end of the guide groove 353 is located below the outlet end of the mesh belt conveying mechanism 33, which facilitates the gravel at the outlet end of the mesh belt conveying mechanism 33 to directly fall into the guide groove 353. The guide groove 353 guides the gravel to the inlet end of the second gravel conveying mechanism 4.

[0033] Further, in the embodiment, the inlet end of the mesh belt conveying mechanism 33 is lower than the outlet end, i.e., the mesh belt conveying mechanism 33 is arranged obliquely, which is beneficial to prolong the dehydration time of the gravel on the mesh belt conveying mechanism 33. For example, the gravel can roll back along the inclined mesh belt to prolong the dehydration time.

[0034] Further, in the embodiment, the wastewater recovery device 6 includes a first sedimentation tank 61 and a second sedimentation tank 62 connected in series. The water inlet of the first sedimentation tank 61 is connected to the water collecting groove 34 through a pipeline. The first sedimentation tank 61 can preliminarily sediment large particles and impurities, and is equipped with a regularly cleaned sedimentation device to prevent blockage. The second sedimentation tank 62 further sediments fine suspended particles to ensure the purification effect of the wastewater. The treated wastewater meets the discharge standard, reducing the pollution to the environment.

[0035] Further, as shown in Figure 1 , in the embodiment, the water outlet of the second sedimentation tank 62 is connected to a discharge ditch 63.

[0036] Further, in the embodiment, the first gravel conveying mechanism 2 and the second gravel conveying mechanism 4 are both conventional belt conveying mechanisms.

[0037] Further, in the embodiment, the receiving station 7 is provided with a transport ship 8. The transport ship 8 is used to receive the gravel cleaned and dehydrated below the outlet end of the second gravel conveying mechanism 4, and then transport the gravel to other places.

[0038] Further, in the embodiment, the spraying mechanism 5 is a conventional mechanism, which includes a spray head arranged above the first gravel conveying mechanism 2 and a water supply assembly connected to the spray head.

[0039] Further, in the embodiment, the gravel supply device 1 can include a stock bin above the first gravel conveying mechanism 2 and a valve arranged at the bottom of the stock bin. The stock bin is used to store gravel.

[0040] Although the utility model has disclosed as above with preferable embodiments, however, it is not used to limit the utility model. Any skilled person in the art, without departing from the technical scheme range of the utility model, can utilize the above disclosed technical content to make many possible changes and modifications to the utility model technical scheme, or modify as equivalent variation equivalent embodiment. Therefore, any simple modification, equivalent variation and modification made to the above embodiments according to the technical essence of the utility model, which does not depart from the content of the technical scheme of the utility model, should fall within the protection scope of the technical scheme of the utility model.
