Furthermore, be provided with the first limiting plate that the cross-sectional shape is "L" shape on the division board, the shape of ring magnet's bottom is the T font, ring magnet's bottom and first limiting plate conflict.

Furthermore, a plurality of water holes are formed in the surface of each annular magnet, and the annular magnets are arranged at intervals.

Further, the top cover is connected with the barrel through bolts.

Furthermore, the inner wall of filter screen is the zigzag, stainless steel brush laminates with the inner wall of filter screen mutually.

Has the advantages that: the annular magnet is arranged in the cylinder body, so that scrap iron can be adsorbed, and the possibility of contact between the scrap iron and the inner wall of the stainless steel brush or the filter screen is avoided.

Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

Examples

The utility model provides a self-cleaning filter, including barrel 1, water inlet 2, delivery port 3, filter screen 4, motor 5, stainless steel brush 6, blowoff valve 7.

The barrel 1 is cylindrical, the water inlet 2 is positioned at the upper end of the barrel 1, the water outlet 3 is positioned at the position, close to the lower end, of the middle of the barrel 1, the drain valve 7 is positioned at the bottom of the barrel 1, and the motor 5 is positioned at the top of the barrel 1. The self-cleaning filter also comprises a partition plate 8, wherein the partition plate 8 is positioned between the filter screen 4 and the water inlet 2, the middle part of the partition plate 8 and the middle part of the filter screen 4 can be mutually communicated, and the position of the water outlet 3 is positioned at the lower side of the partition plate 8. The rotating shaft of the motor 5 is fixed with the stainless steel brush 6, and the stainless steel brush 6 is contacted with the inner wall of the filter screen 4 and is positioned at the same horizontal height.

The utility model discloses a use does: sewage flows into the upper end of the cylinder body 1 from the water inlet 2 and falls down to the inside of the filter screen 4 from the middle part of the partition plate 8, the sewage seeps out from the inside of the filter screen 4, and filter residues in the sewage are filtered by the filter screen 4 and remain on the inner wall of the filter screen 4. The starting motor 5 drives the stainless steel brush 6 to brush out the residual filter residue on the filter screen 4, and simultaneously the blowoff valve 7 is opened to discharge the filter residue out of the cylinder body 1. The filter screen and the stainless steel scraper are in mutual contact by adopting a zigzag structure.

As shown in figures 1 and 2, in order to remove the iron filings in the sewage, the self-cleaning filter also comprises at least one annular magnet 9, a placing chamber 10, a second limit plate 11 and a top cover 12. The top cover 12 is arranged on the top of the cylinder 1, the top cover 12 is connected with the top of the cylinder 1 in a bolt connection mode, the second limiting plate 11 is fixed on the lower side surface of the top cover 12, and the placing chamber 10 is arranged in the space between the lower surface of the top cover 12 and the lower surface of the partition plate 8.

As shown in fig. 3, a first limiting plate 13 is fixed on the upper surface of the partition plate 8, the longitudinal cross-sectional shape of the first limiting plate 13 is approximately "L" shaped, the number of the ring magnets 9 is preferably 4, four ring magnets are located in the same circumference, the number of the first limiting plates 13 is also four, the longitudinal cross-sectional shape of the bottom of each ring magnet 9 is approximately "T" shaped, and the bottom of each ring magnet 9 collides with the first limiting plate 13.

The number of the second limiting plates is also four, and the shape surrounded by each second limiting plate is just the same as the shape of the top of the annular magnet 9, so that the purpose of limiting the top position of the annular magnet 9 is achieved.
