Description

Automatic froth scraping device for grinding fluid coarse filtering tank

Technical Field

The utility model relates to the technical field of wastewater treatment, in particular to an automatic foam scraping and floating device for a grinding fluid coarse filter tank.

Background

During the production process of the bearing, a plurality of grinding fluids are generated, and the grinding fluids are usually collected into a coarse filter tank for coarse filtration treatment, then discharged into a fine filter tank for fine filtration, then flow into the next working procedure for post treatment, and are recovered for secondary use after reaching standards. Wherein, because the discharge amount of the grinding fluid is large, when the grinding fluid flows into the coarse filter tank, larger torrent is generated, and most metal residues in the grinding fluid float on the torrent water surface, namely a large amount of floating foam is formed. These floating foams are difficult to settle to the bottom of the coarse filtration tank in a short time, and even if settled to the bottom, they are subjected to the action of a subsequent torrent and are again floated on the water surface. Therefore, the froth on the coarse filtration surface needs to be scraped off at regular time.

At present, the floating foam is mostly scraped by a slag scraper. For example, chinese utility model with authority publication number CN 214653774U discloses a froth scraping mechanism, which comprises two guide rail frames, scraping plates, scraping rods and a drag hook, wherein the two guide rail frames are symmetrically arranged, guide rods are fixed in the guide rail frames, the number of the scraping plates is two, one side of each scraping plate is fixed with a sliding sleeve, and the sliding sleeve is in sliding clamping connection with the guide rods; the cleaning surface of the scraping plate is provided with a plurality of rows of cleaning brushes, a storage chute is formed between every two adjacent cleaning brushes, limiting chutes are formed in the inner walls of two sides of the storage chute, a scraping rod is inserted in the storage chute in a sliding manner, and the cleaning brushes are arranged at the bottom of the scraping rod; limiting sliding blocks are fixed on two sides of the scraping rod and are in sliding clamping connection with the limiting sliding grooves; the scraper plate is fixedly provided with a connecting ring, and the drag hook is movably clamped with the connecting ring. The floating foam scraping mechanism mainly uses the cleaning brush to scrape floating foam, but because the grinding fluid is discharged into the floating foam generated by the coarse filter tank to contain a large amount of metal residue particles, the floating foam scraping mechanism has a general scraping effect on the floating foam, and the cleaning brush needs to be cleaned frequently, so that the use is more complicated. For this purpose, we provide an automatic froth scraping device for grinding fluid coarse filtration tanks.
