Problems solved by technology

[0005] At present, compared with other pre-filters, the backwash pre-filter has some improvements in technology, but when encountering the intercepted matter clogged in the filter mesh, it is necessary to open the filter bottle to take out the filter mesh, and use an auxiliary filter to remove the filter. Brush (can be replaced by toothbrush), air gun and other tools to clean up, but also bring trouble to users

Embodiment 1

[0029] Such as figure 1 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, an inverted pre-filter includes a pre-filter body 19, and the pre-filter body 19 includes a connecting part 1, a bottle body 2, a filter cartridge 3 and a flexible scraper in the shape of a hollow cylinder as a whole. Cleaning device 5.

[0030]The upper end of the connecting part 1 is provided with three bottle body interface 10, filter cartridge interface 11 and inner water inlet interface 12 arranged in sequence from outside to inside in concentric circles. The three concentric circle interfaces mutually form an outer ring cavity 13 and an inner ring cavity. An annular cavity 14, a sewage discharge chamber 15 is arranged inside the bottom end of the connecting part 1, and the sewage discharge chamber 15 is connected with the inner annular cavity 14 at its upper end, and a sewage discharge device 4 is also arranged therein, and the sewage discharge device 4 includes...

Embodiment 2

[0037] Such as figure 2 , Figure 5 , Figure 9 , Figure 10 As shown, an O-ring sealing structure 30 is provided on the bottom and top periphery of the filter cartridge 3 and forms a static sealing fit with the inner wall of the bottle body 2 and the inner wall of the filter cartridge interface 11; It is in the shape of a hollow cylinder, and its bottom port and the inner water inlet interface 12 form a dynamic sealing relationship. The top of the bottle body 2 is provided with a groove 20 and a through hole 21. The top of the flexible cleaning device 5 is set on the The groove 20 and the through hole 21 form a dynamic sealing fit relationship, and its outer port is connected with a hand wheel 6 or an electric actuator 7, and a polygonal inner surface is arranged at the top of the flexible scraping and cleaning device 5. Hole 8, the section of the outer end of the valve stem 40 is also polygonal and adapted to the inner hole 8 (in this embodiment, the polygon is hexagonal...

Abstract

The invention relates to the technical field of water treatment, in particular to an inversion type pre-filter. The invention provides a novel technology for combining a novel built-in blow-down valvestructure and a flexible scraping brush decontamination device. The methods that the conventional pre-filter generally adopts a technological approach of decontamination by an external ball valve andthe cylinder, the filter cartridge and the like of the pre-filter are generally arranged at the lower end of a connecting part structurally are completely changed. Compared with the traditional pre-filter, the inversion type pre-filter disclosed in the invention has an inverted structure.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an inverted pre-filter technology, which provides a new technology combining a new built-in sewage valve structure and a flexible scraper cleaning device, completely changing the existing The filter generally adopts the technical approach of external ball valve sewage discharge and cleaning technology, and generally puts the bottle and filter cartridge of the pre-filter at the lower end of the connection part in structure, and adopts a method that is different from the traditional pre-filter The comparison presents a structural inversion. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people began to have higher requirements for water and dietary health in daily life. Due to secondary pollution such as rust and sediment in the water supply of the city, the water quality of household water det...
