Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

By figure 1 to 3, the utility model discloses an interior barrel 1 and outer barrel 2, interior barrel 1 and outer barrel 2 coaxial arrangement, form a confined intermediate layer 3 between two barrels, drain pipe 4 is installed to 3 lower extremes of intermediate layer, interior barrel 1 lower extreme stretches out outside barrel 2, the upper end is located outer barrel 2, first end cover 5 is equipped with soon to 1 lower extreme of interior barrel through the screw thread, a filter screen 6 and a second end cover 7 are installed to the upper end, be equipped with vertical through-hole 8 on the second end cover 7, filter screen 6 is on barrel 1 including 7 pressure equipment of second end cover, third end cover 9 is equipped with soon to the upper end of outer barrel 2, install a feed liquor pipe 10 in the interior barrel 1, the lower extreme of feed liquor pipe 10 extends the bottom of interior barrel 1, the upper end stretches out outside barrel 2 from the lateral wall of interior barrel.

The lower end of the liquid inlet pipe 10 is provided with a bowl-shaped baffle 11, and the liquid medicine in the liquid inlet pipe 10 flows into the baffle 11 and then overflows from the upper edge of the baffle 11, so that the liquid medicine is prevented from directly impacting the bottom of the inner cylinder body 1 to stir deposited impurities.

The inner surface of the baffle is densely distributed with cilia 12, and the cilia 12 can further buffer the liquid flow.

Third end cover 9 on install a vertical pivot 13, the lower extreme of pivot 13 extends filter screen 6 below, the upper end is located third end cover 9 top and is connected with motor 14, the lower extreme of pivot 13 is installed a horizontally and is scraped pole 15, the upside of scraping pole 15 is equipped with brush hair 16, brush hair 16 and filter screen 6's lower surface contact.

And a sealing ring 17 is arranged between the rotating shaft 13 and the third end cover 9.

When the utility model is used, the liquid medicine to be filtered flows into the inner cylinder body 1 from the liquid inlet pipe 10, the liquid level in the inner cylinder body 1 gradually rises, finally overflows to the interlayer 3 between the two cylinder bodies from the top of the inner cylinder body 1 through the filter screen 6 and the through holes 8 on the second end cover 7, and then flows out from the liquid outlet pipe 4; because the filter screen 6 is located the top, consequently can not deposit a large amount of impurity on the filter screen 6, impurity deposit in the liquid medicine is including on the bottom of barrel 1 is first end cover 5 to slowed down the speed that filter screen 6 blockked up greatly, guaranteed the unobstructed of play liquid.

After filtering for a period of time, opening the first end cover 5, cleaning impurities on the first end cover, and then screwing the first end cover on the inner cylinder 1; when the filter screen 6 is adhered with more impurities, the first end cover 5 is opened, the motor 14 is started, the motor 14 drives the scraper blade to rotate through the rotating shaft 13, meanwhile, the liquid outlet pipe 4 is communicated with a pressure water source, water flows into the interlayer 3 through the liquid outlet pipe 4 and then flows into the inner cylinder 1 from the upper end of the inner cylinder 1 through the filter screen 6, the water flow is matched with the scraper blade to back flush the filter screen 6, and the impurities on the water flow are removed and discharged from the lower end of the inner cylinder 1; when the filter screen 6 needs to be replaced, the third end cover 9 and the second end cover 7 are opened, the scraper and the filter screen 6 are taken down, and the new filter screen 6 is replaced and then assembled.

The utility model discloses a filtration mode of overflow formula has avoided impurity in the extract to cause the problem that filter screen 6 blockked up in a large amount of deposits on filter screen 6, can keep long-time unobstructed of filter screen 6, and can conveniently carry out backflushing and change to filter screen 6.
