Use slag
(oil) scraper slag (oil) scraper slag (oil) scraper is mainly used for advection (rectangular) sedimentation tank, especially in sewage treatment engineering grit tank, sedimentation tank, secondary sedimentation tank and grease trap and other rectangular pool bottom sediment scraping and elimination, at the same time can be the liquid level oil slick, dross skimming. The specific structure is simple, one machine doubles as a dual purpose, the installation, operation and maintenance are cheap, and the operation is safe and reliable.

Structure and working principle
The skimmer is divided into two types according to the process structure and working mode.
PJ-T type lifting plate type sprinkler (oil) scraper.
It is mainly composed of drive reduction device, skimmering mechanism, sludge discharge mechanism, lifting and lowering drum and electronic control device and other parts on the frame of an integral device.
Under the instruction of the electronic control device, the skimming and scraping mechanism run in a straight line with the frame along the track laid on the pool surface. The lifting and lowering drum is regularly (fixed) to lift or lower the scraper, so that the skimming and scraping sludge work in one direction, and scrape the sediment and liquid level oil residue at the bottom of the pool in the sludge collection tank and the oil discharge pipe discharge outside the pool.
PJ-L type chain traction type skimmer (oil) scraper is mainly composed of a reduction drive device fixed on the pool surface and a traction chain with scraper
set in the pool, a transmission chain payment and tensioning device, and a safety protection device.
The deceleration drive device transmits the power to the traction chain through the sprocket, drives the scraper to guide the directional rotation along the upper and lower rails in the pool for continuous operation, and during the operation, the scraper continuously scrapes the sediment at the bottom of the pool and the oil residue on the pool surface in the sludge collection tank and the slag discharge pipe is discharged outside the pool.

Technical data and installation size chart

Note: The installation size depends on the actual size of the sedimentation tank and is provided separately according to requirements
