Sealing, the other end are equipped with the rhs-structure of water inlet pipe, and described high-pressure hose one end connects water inlet pipe, and the other end connects water injection pipe,
The upper end of scraper base is arranged in the scraper, and the lower end of the scraper base is evenly equipped with nozzle along its length, the nozzle
Open Side Down, and the scraper base is in tilted layout on groove body, and the blade of the scraper and filter disc setting in a certain angle are described to scrape
The point of a knife of knife has at regular intervals with filter disc.
Preferably, the upper end of the scraper base is provided with scraper gusset piece, for coupling scraper, the lower end of the scraper base
It is evenly equipped with nozzle bearing, for coupling nozzle.
Preferably, the scraper is fixed by screws on scraper gusset piece.
Preferably, the scraper base is fixed on groove body by scraper base connecting plate.
Preferably, the lower end surface of the scraper base is obliquely installed with groove body top surface in 45 °.
Preferably, the nozzle spray shape is sector.
The present invention also provides a kind of pressing filters, including the above-mentioned scraper device with filter cloth cleaning function.
Beneficial effects of the present invention:
The present invention is provided with nozzle in scraper device, and it is good, raw can to carry out cleaning filter cloth, the regenerability of filter cloth online
Produce that high-efficient, filter cloth service life is long, maintenance cost is low, the labor intensity of worker is low；Scraper base is in tilted layout on groove body, makes
The oblique filter cloth of nozzle is obtained, covering cleaning can be carried out to filter cloth, and nozzle sprays to obtain the fan-shaped shape of water, big with clean range,
The fast feature of cleaning speed；Point of a knife and the filter disc tool of the blade of scraper and filter disc setting in a certain angle, scraper are at regular intervals,
It is not only able to avoid scraping rotten filter cloth, and scraper can not be caused to remain and block when wiping the filter residue on filter cloth off.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is sectional view of the Fig. 1 along line A-A.
In figure: 1- groove body, 2- filter disc, 3- high-pressure hose, 4- water injection pipe, 5- scraper base, 6- scraper, 7- nozzle, 8- water inlet
