XHJG type gantry scraper
Keywords: pretreatment equipment, aeration equipment
Product Description
XHJG type gantry sludge scrapers are generally used in horizontal flow sedimentation tanks in wastewater treatment projects and water supply and drainage projects. The sludge scraper uses a reciprocating motion to scrape the settled sludge at the bottom of the tank to a sludge sump at one end for discharge, with water entering at one end and exiting at the other, and a sludge sump at one end of the bottom of the tank. The track gauge is generally around 4-25m. When the tank width is large, a multi-tank shared intermediate support structure can be made.
When equipped with an upper surface oil or scum removal device, it is similar in structure and function to the XGYZ type oil and scum scraper.
Its characteristics:
● The hinged scraper arm can automatically scrape in layers, preventing jamming;
● A variable speed transmission mechanism can be used to achieve a quick return function;
● Full stroke or half stroke operation can be achieved according to process requirements;
● It has a rake lifting function, which can achieve load reduction or unidirectional sludge scraping;
● When the span is large, a synchronous motor is generally used, and there is no track climbing phenomenon;
● The sludge scraper is equipped with rubber plates and rollers, ensuring thorough and reliable sludge scraping;
● A wide range of retention times can be selected according to the nature of the water source (large tank length range);
● Wide range of applications, suitable for wastewater treatment plants, waterworks, steel plants, and power plants.
Working principle
The gantry sludge scraper generally stops at the outlet end of the sedimentation tank. First, the driving travel reducer is started, and the sludge scraper starts to scrape sludge towards the inlet end. When it reaches the inlet end, the travel switch on the gantry crane touches the travel stop block, and the reducer stops running. The hoisting mechanism begins to lift the scraper to a certain height, and the travel reducer starts to run in reverse. After reaching the end point, the reducer stops running, and the hoisting mechanism lowers the scraper to the bottom of the tank (this is one work cycle). The sludge scraper waits for the next work command and repeats the above work, thus reciprocating to scrape the sludge at the bottom of the tank and the scum on the water surface. The sludge accumulated in the sludge sump is discharged from the tank by a sludge pump (if it needs to be matched, it needs to be specified), and the upper scum is discharged by a pipeline scum collecting pipe installed at the outlet end of the sedimentation tank (if it needs to be matched, it needs to be specified).
