XHXS type bridge sand suction machine

Bridge-type sand suction machines are mainly used in the horizontal flow aeration sedimentation tanks of wastewater treatment plants to remove settled sand from the bottom of the sedimentation tank. The sand suction machine moves back and forth along the length of the sedimentation tank on steel rails. The sand suction pump on the machine sucks up the sand-water mixture from the bottom of the tank and discharges it to a water channel, where it enters the supporting equipment (sand-water separator) for separation. The main difference from the cyclone sand separator is that a scum board can be installed on the bridge-type sand suction machine to scrape the floating scum on the water surface to the scum collection tank at the end of the tank.

Product Description

The bridge-type sand suction machine is mainly used in the horizontal flow aeration sedimentation tank of wastewater treatment plants to remove settled sand from the bottom of the sedimentation tank. The sand suction machine moves back and forth along the length of the sedimentation tank on steel rails, and the sand suction pump on the machine sucks out the sand-water mixture from the bottom of the tank and discharges it to the water ditch, where it enters the supporting equipment (sand-water separator) for separation. The main difference from the vortex sand separator is that a scum removal plate can be installed on the bridge-type sand suction machine to scrape the floating scum on the water surface to the scum collection tank at the end of the tank.

Sand suction pumps are available in three types: air-lift, submersible, and dry pumps.

Its characteristics:

● Large processing capacity, advanced technology, simple structure.

● Uses a non-clogging submersible pump to suck sand, ensuring safety and reliability.

● Synchronous transmission, stable operation.

● Simple operation and easy maintenance.

Working principle

Wastewater enters the horizontal flow sedimentation tank at a certain flow rate. As the flow rate decreases, the sand particles in the wastewater settle to the bottom of the tank under their own gravity. The sand suction machine, installed across the top of the tank, moves back and forth along the track on the top of the sedimentation tank. The sand suction pump on the machine sucks out the sand-water mixture from the bottom of the tank and passes it through a sand collection tank (normally a concrete structure) into a sand-water separator for further sand-water separation. At the same time, the scum removal device on the machine scrapes the floating scum on the water surface to the scum tank at the end of the tank.
