[0028] The utility model provides a kitchen waste sand separation device, see Figure 1 and Figure 2 , Figure 1 Schematic diagram of the structure of a food waste sand separation device, the food waste sand separation device comprises: a sand settling machine 1, a pulse sand flushing device 2 and a sand remover 3;

[0029] The desander 3 comprises a first cylinder 31, a spiral rod 32 and a power mechanism 33;

[0030] The first cylinder 31 is arranged at a preset angle on one side of the sand settling machine 1, and the lower end of the first cylinder 31 is connected to the discharge end of the sand settling machine 1, and the discharge end is located at the bottom of the sand settling machine 1;

[0031] The screw rod 32 is disposed on the first cylinder 31 and is in transmission connection with the power mechanism 33. The screw rod 32 rotates to drive the impurities to be discharged from the discharge port of the first cylinder 31. The discharge port is located at the upper end of the first cylinder 31.

[0032] The pulse sand flushing device 2 is disposed at one side of the first cylinder 31 and is in communication with the first cylinder 31 . The pulse sand flushing device 2 can apply pulse water pressure to the sand settling machine 1 through the first cylinder 31 .

[0033] It should be noted that the pulse sand flushing device 2 is arranged on one side of the first cylinder 31 and is connected to the first cylinder 31. When the pulse sand flushing device 2 is pulsating, it will transmit the pulse to the sand settling machine 1, thereby destroying the bridging structure formed by the solid impurities. At this time, the solid impurities will sink to the bottom of the sand settling machine 1 under the action of their own gravity, and follow the rotation of the screw rod 32 of the sand remover 3 to be discharged from the discharge port of the first cylinder 31.

[0034] It is worth noting that the pulse sand flushing device 2 of the present application is arranged close to the lower end of the first cylinder 31 . Therefore, when the pulse sand flushing device 2 is working, most of the pulse water pressure can act on the sand settling machine 1 .

[0035] In the embodiment of the utility model, the first cylinder 31 is arranged at a preset angle on one side of the sand settling machine 1, and the lower end of the first cylinder 31 is connected to the discharge end of the sand settling machine 1, and the discharge end is located at the bottom of the sand settling machine 1, and the screw rod 32 is arranged on the first cylinder 31 and is in transmission connection with the power mechanism 33, and the screw rod 32 rotates to drive the impurities to be discharged from the discharge port of the first cylinder 31, and the discharge port is located at the upper end of the first cylinder 31, and the pulse sand flushing device 2 is arranged on one side of the first cylinder 31 and is connected to the first cylinder 31, and the pulse sand flushing device 2 can apply pulse water pressure to the sand settling machine 1 through the first cylinder 31. Through the food waste sand separation device disclosed in the above embodiment, since the pulse sand flushing device 2 can apply pulse water pressure to the sand settling machine 1 through the first cylinder 31 to destroy the bridge structure formed by solid impurities, the solid impurities can sink to the bottom of the sand settling machine 1 under the action of their own gravity, thereby eliminating the blockage problem caused by the bridge formed by the solid impurities.
