Purpose:

The DXL type center driven single tube suction dredger is suitable for circular secondary sedimentation tanks with large pool diameters and surrounding water inflow and outflow. Its unique water distribution and sludge discharge methods effectively increase the capacity load of the sedimentation tank and reduce the footprint of the secondary sedimentation tank.

Structural principle:

The DXL type center driven single tube suction machine consists of a fixed working bridge, a center drive device, a center column, a center vertical frame, a mud collection cylinder, a suction pipe, a scraper plate, a floating slag scraper, a floating slag funnel and bracket, a water blocking skirt plate, a water distribution pipe, a water outlet trough and weir plate, a rotating arm tension cable, and a suction pipe tension cable.

The mixed liquid of activated sludge flows into the diversion area through the water distribution hole of the inlet tank, and flows towards the center of the tank through the bottom of the water blocking skirt. The sludge gradually settles at the bottom of the tank, flows into the suction pipe under the action of water pressure, and flows towards the central mud collection cylinder. It flows into the mud collection well outside the secondary sedimentation tank through the mud collection pit and pipeline at the lower part of the mud collection cylinder, and is discharged by adjusting the flow rate through the sleeve valve. The supernatant overflows from the water outlet tank around the pool body. Scum is collected by a scum skimming mechanism, scraped into a scum funnel, and discharged outside the pool through a pipeline.

characteristic:

1. High sludge concentration: The central transmission single tube suction machine is designed based on hydraulic theory and sludge settling characteristics, using variable diameter and irregular shaped pipes to form suction pipes. The balanced suction design ensures high sludge concentration. Compared with other suction machines, it can increase sludge concentration by 20% to 30%, thereby greatly improving sludge dewatering efficiency and reducing sludge dewatering costs.

2. High volume utilization rate: Compared with the traditional central inlet method, the peripheral inlet method can increase the volume load of the sedimentation tank by more than twice, thereby improving the volume utilization rate of the sedimentation tank;

3. This product adopts advanced drive system and overload protection device, which operates reliably, consumes less energy, and has a long service life.

4. Sleeve valve controls sludge discharge, easy to operate.

characteristic:

1. Please indicate when accessories such as water outlet weir plate, water blocking skirt plate, and slag discharge weir door are needed.

2. Please specify the material and surface treatment anti-corrosion requirements for the main components of the equipment.

3. Our company can provide users with comprehensive services such as design, installation, and debugging.
