Use
bridge sand suction machine is mainly used for sand water treatment of urban sewage treatment plant or tap water aeration grit tank, the grit at the bottom of the sand, cinder and other larger particles and sewage mixture to the pool side of the sand discharge tank: according to user requirements, oil skimming, slag skimmering device can be added.

Structure and working principle
The equipment adopts mobile bridge type, pump suction type, when the sand suction machine is not working, that is, it stops at the inlet end: when the sand suction machine is working, the car is driven under the command of electric digging, when driving along the water, first put down the skimmer board, scrape the dross and skim to the steel skimmer groove at the end of the pool; When driving in the opposite direction, the slag rake is lifted and leaves the liquid surface to prevent the dross from going retrograde: the sand water at the bottom of the pool is discharged into the sand collection tank at the edge of the pool by the sand suction pump through the suction pipe, and then flows into the sand water separator through the pipeline for the next step of treatment, and the round-trip work movement is carried out according to this, so as to achieve the purpose of sand absorption, sand discharge and slag spreading.

Technical data and installation size chart

Main features
: reciprocating sand absorption, skimming, high efficiency, simple structure;
The vortex type low-lift submersible pump is used to suck sand and does not require water diversion operation. No clogging, wear resistance, safe and reliable; One-way skimming, the pool surface is relatively clean
and the grit is circulated through aeration, the organic matter on the sand has been washed, and the sand particles are discharged without odor;
The equipment is easy to operate, and the operation of the equipment can be directly controlled on the spot and remotely.
