The objective of the invention is to realize by following technical scheme, developed a kind of cascaded filter for purifying complex granule foreign substance, this filter comprises valve (2), flange (3), screen pack (4), the residual pipe of granule foreign (10), screen pipe (12), it is characterized in that: described screen pipe (12) main body is set to the cylindrical filter structure, this cylindrical filter structure left end is provided with import (1), right-hand member is provided with outlet (9), and valve (2) is set at import and export, the centre sets gradually I level screen pack (4) by flange (3), II level screen pack (6), III level screen pack (7), IV level screen pack (8), leak is set and connects the residual pipe of granule foreign (10) at screen pack lower end parts at different levels, each delivery port that recoils connects by valve (2).
Described screen pack is made with PVC, PP, steel wire or nylon yarn material, and screen packs at different levels aperture is the 100-5000 micron.
Described flange (3) is connected with screen pipe (12) by rivet (5), and the distance between its each flange (3) is 5-50 centimetre.
The residual pipe of described granule foreign (10) is made by PVC, PP or steel material, and granule foreign backwash outlet (11) is set on the residual pipe of granule foreign (10), and valve (2) is set in the exit.
The present invention better realizes in order to ensure above-mentioned technology, and a kind of cascaded filter for purifying complex granule foreign substance preparation method is provided, and it comprises following method step:
1., each part mold of preparation filter body;
2., 1. each part mold of process preparation is carried out die cast or other machine-shaping;
3., the filter screen aperture is by the arrangement of successively decreasing in turn of from inlet water to outlet water order;
4., the fixing flange that adopts of each grade filter screen connects;
5., after water inlet leading portion, the water outlet, backwash outlet pipe place and total backwash delivery port all are provided with a pneumatic or electronic autocontrol valve and assemble before each grade filter screen.
Advantage of the present invention is: simple in structure, design science, filter and backwash combine, the recoil of being convenient to filter screens at different levels is cleaned, be difficult for blocked because of being applicable to the removing of complex granule foreign in the fluid, long service life, economical and practical, suitable a large amount of production.
Description of drawings
Fig. 1 is a step in-line filter structure chart;
The specific embodiment
Referring to Fig. 1, the present invention has developed a kind of cascaded filter for purifying complex granule foreign substance, takes following steps:
This filter comprises valve (2), flange (3), screen pack (4), the residual pipe of granule foreign (10), screen pipe (12), it is characterized in that: described screen pipe (12) main body is set to the cylindrical filter structure, this cylindrical filter structure left end is provided with import (1), right-hand member is provided with outlet (9), and valve (2) is set at import and export, the centre sets gradually I level screen pack (4) by flange (3), II level screen pack (6), III level screen pack (7), IV level screen pack (8), leak is set and connects the residual pipe of granule foreign (10) at screen pack lower end parts at different levels, each delivery port that recoils connects by valve (2).
Described screen pack is made with PVC, PP, steel wire or nylon yarn material, and screen packs at different levels aperture is the 100-5000 micron.
Described flange (3) is connected with screen pipe (12) by rivet (5), and the distance between its each flange (3) is 5-50 centimetre.
The residual pipe of described granule foreign (10) is made by PVC, PP or steel material, and granule foreign backwash outlet (11) is set on the residual pipe of granule foreign (10), and valve (2) is set in the exit.
The present invention better realizes in order to ensure above-mentioned technology, and a kind of cascaded filter for purifying complex granule foreign substance preparation method is provided, and it comprises following method step:
1., each part mold of preparation filter body;
2., 1. each part mold of process preparation is carried out die cast or other machine-shaping;
3., the filter screen aperture is by the arrangement of successively decreasing in turn of from inlet water to outlet water order;
4., the fixing flange that adopts of each grade filter screen connects;
5., after water inlet leading portion, the water outlet, backwash outlet pipe place and total backwash delivery port all are provided with a pneumatic or electronic autocontrol valve and assemble before each grade filter screen.
Normal applying working condition of the present invention, as shown in Figure 1.At this moment, inlet valve 2-1 and flowing water Valve 2-2 all are in open mode, and back flush valves 2-3 at different levels and total back flush valves 2-4 all are in closed condition.Pretreatment fluid flows from the direction of import 1 to outlet 9, and granule foreigns at different levels are retained in respectively between the filter screen in different apertures.The backwash operating mode, at this moment, filter stops filtration treatment work, and inlet valve is closed, and flowing water Valve is opened and is changed backwash water inlet inlet into, and total back flush valves is opened.Back flush valves at different levels are then opened step by step, and other back flush valves at different levels are all closed, and then the particulate matter held back of this grade filter screen is backwashed fluid and is cleaned by total backwash outlet and take away.That is, when i level back flush valves was opened, non-i level back flush valves was all closed, and by carrying out to 0 grade order from last level, filter screens then at different levels obtain recoil one by one and clean.Backwashing procedures can be controlled the cleaning that regularly recoils automatically by commercially available automatic valve; Also can be by the cleaning that regularly recoils of artificial execution backwashing procedures.For some special process that should not stop or the excessive technology for the treatment of capacity, should adopt the parallel connection of a plurality of step in-line filters to use, at this moment, when some step in-line filters carry out backwashing procedures or repair and replacement, do not influence the normal operation of other filters.When a plurality of step in-line filters parallel connections were used, the normal operation of its each filter and backwashing procedures were with the step in-line filter that uses separately.
In addition, the present invention and not meaning that by schematic diagram and specification limits to, and can change to some extent under the prerequisite that does not break away from design aim and principle thereof.
