Through the cooperation between the two support rods 58 and the two first mounting seats 56 and the two second mounting seats 57, when the equipment is transported and delivered, the connection between the two support rods 58 and the two first mounting seats 56 is loosened, and the two support rods 58 are connected with the two second mounting seats 57, so that the mounting rack 55 is turned down and supported on the two support rods 58, the cyclone separator 51 is stored, the height of the equipment is reduced, the equipment can be transported in whole, and the installation difficulty is reduced. Specifically, the overflow tank 53 is connected with the upper end of the cyclone separator 51 through an elbow pipe 59. When the cyclone separator 51 works, the overflow sewage containing mud is sent into the overflow tank 53 through the elbow pipe 59 for buffering, so as to prevent the siphon phenomenon caused by the too long water outlet pipe 54, and to cause the instability of sand setting at the bottom of the cyclone separator 51. Further, the water inlet pipe 52 is a hose, and a pressure detection device for detecting the pipeline pressure is arranged on the water inlet pipe 52, so as to adjust the frequency of the sewage pump 42 and ensure the ideal working condition of the cyclone separator 51.

The floating ball 435 can be driven by the continuously rising water level to rotate the sealing pipe 434 upward to seal the end of the flow guide pipe 433, so that the sewage in the overflow tank 53 cannot continue to enter. When the liquid level is lower than the preset height, the floating ball 435 will descend to drive the sealing pipe 434 to rotate downward to open the flow guide pipe 433, so that the sewage containing mud in the overflow tank 53 enters the sewage tank 41 for water replenishment. When the liquid level reaches the preset height, the floating ball 435 floats to drive the sealing pipe 434 to rotate upward to seal the lower end of the flow guide pipe 433, so as to prevent the sewage containing mud from continuing to flow into the sewage tank 41. Specifically, the sewage tank 41 is provided with a drainage pipe 411 connected with the side of the lower end of the water outlet pipe 54, and the sewage in the sewage tank 41 and the sewage containing mud in the overflow tank 53 can also be discharged outward through the drainage pipe 411. Further, the sewage tank 41 is provided with a feeding port 412 and a water replenishment port 413. The feeding port 412 can be connected by a pipeline to send the mortar raw material into the sewage tank 41 for preliminary mudification and then into the cyclone separator 51 for cyclone separation, so as to realize one machine with multiple functions. The water replenishment port 413 can be connected with a water source to appropriately replenish water for the sewage tank 41.

[0036] The maintenance platform 6 is installed on the sewage tank 41 and can be used by workers to maintain the equipment.

[0037] The application limits the structural composition of the device, sets the dewatering screen 31 in cooperation with the cyclone separation device 5, and sets the first screen 312 and the second screen 313 on the dewatering screen 31, so as to realize the screening and dewatering treatment of two kinds of mortar raw materials with different particle sizes. The process originally requiring multiple sand washing machines is integrated into one device, the number of belt conveyors for connecting the sand washing devices can be reduced, the application is suitable for sand washing sites with low production capacity, one machine with multiple functions is realized, and the occupied area is greatly reduced.

[0038] The above is only a preferred embodiment of the application, and therefore cannot limit the range of the application. Equivalent changes and modifications made according to the application range and content of the specification should still be within the scope of the application.
