The bridge-type sand suction machine consists of the following parts: main beam, track, drive device, frame, sand suction system, and slag skimming device.

[0003] The aerated grit tank uses a bridge-type sand suction machine to collect sand and gravel. However, the sand suction port of the bridge-type sand suction machine is often blocked and the bridge-type sand suction machine cannot complete the sand discharge operation. The sand suction ports are located at the bottom of the tank. When the sand suction ports and sand suction pipes are blocked, the repair work requires emptying the aerated grit tank, which is time-consuming and labor-intensive, and it is difficult to quickly remove the blockage.
