ZBXN Peripheral Drive Half-bridge Suction Dredger

Application

It is used in the circular secondary sedimentation tank of the sewage treatment  plant to scrape the sludge settled at the bottom of the tank to a group of suction pipe  nozzles arranged along the radius, and then discharge it through the central sludge  discharge pipe for sludge return or concentration and dehydration. At the same time,  the scum on the pool surface is skimmed to the slag collecting hopper, and discharged  out of the pool through the slag collecting hopper for further treatment.

Features

1. Simple structure and light weight: due to the use of half-bridge type, there is only  one set of driving devices, and the main girder is also used as a mud trough. Compared  with the full-bridge dredger that is widely used in China, the weight is significantly  reduced.

2. Save operating costs, easy maintenance and management

3. A new type of transmission device can be selected, and the key component in the  drive device—the reducer adopts advanced shaft-mounted type, no need for centering,  no coupling, compact structure, high efficiency and light weight

4. It can be equipped with an over-torque protection mechanism. When the torque  reaches the set value, it will automatically alarm and stop, which is safe and reliable.

Construction and work description ：

ZBXN series mud suction machine is shown in Figure 1 for the surrounding  transmission siphon type, which is composed of the main beam, mud suction pipe  system, siphon suction system, central mud tank, central rotary bearing, drive device,  slag skimming device, collector, control cabinet, etc.

The main beam is driven by the driving device placed in the surrounding area and  rotates around the central axis of the pool. The sludge deposited at the bottom of the  pool is scraped from the mud scraper to each mud suction outlet. Under the action of  poor liquid level, the sludge is discharged to the sludge pit through the mud suction port,  the mud tank, the siphon, the central mud tank and the central sludge discharge pipe.  The upper end of each tube has a regulator to regulate the flow distribution of each tube.  At the same time, the scum on the liquid level is concentrated into the shrinkage area  formed by the skimming plate and the surrounding scum baffle rotating with the main  beam until its closed edge-scraping swing arm. When the swing arm reaches the slag  bucket, the scraping plate on the swing arm is scraped to the mud bucket.

electric control

The start, stop and run time of the equipment can be set according to the user needs,  with PLC interface.
