Description

A kind of large flow self-cleaning filter
Technical field
The utility model relates to agricultural irrigation systems water treatment facilities technical field, refers to especially a kind of large flow self-cleaning filter.
Background technology
Self-cleaning filter is that a kind of filter screen that utilizes is directly tackled impurity in water; remove water body suspension, particle, reduce turbidity, purify water; the generation of minimizing system dirt, bacterium algae, corrosion etc., to purify water and the normal precision equipment of working of other equipment of protection system.
Some self-cleaning filter is for agricultural irrigation technology, for fear of the impact of impurity on irrigation system in water, filter need to be installed in pipeline, use current existing self-cleaning filter on the market to carry out the filtration of irrigation system water quality, situation about often occurring be strainer screen service time not length will get clogged, need often to change screen pack, not only waste time and energy, cost is high, and can interrupt the irrigation work to crops, affect crop growth.
In addition, the cleaning brush of filter is mostly vertical bar shape, while utilizing this cleaning brush to clean filter screen, the rectangular state of tangent line of bristle and filter screen cleans, and this cleaning way easily causes brush board jam, and dirt accumulation is on brush silk, be difficult for discharging, also larger to the resistance of current during cleaning brush running.
Utility model content
The utility model proposes a kind of large flow self-cleaning filter, solved in prior art that strainer screen for agricultural irrigation systems field easily gets clogged and cleaning brush easily causes the problem of brush board jam.
The technical solution of the utility model is achieved in that
A large flow self-cleaning filter, comprising: housing, be positioned at water inlet, delivery port on described housing, and the dividing plate and the self-cleaning mechanism that are positioned at described housing; Described dividing plate is divided into the space in described housing into He Chu hydrospace, water space; Described water inlet is provided with coarse strainer in space, described in go out in hydrospace, to be provided with fie screen; Described self-cleaning mechanism comprises cleaning motor, rotating shaft and cleaning brush, and described rotating shaft is connected with the output of described cleaning motor, and described cleaning brush is spirality.
Described cleaning brush be take the axis of described rotating shaft and is fixedly connected with described rotating shaft as pivot and by a plurality of connecting rods.
The brush board tangent line of described cleaning brush and described rotating shaft be miter angle.
The described housing that goes out hydrospace is provided with blow-off pipe, and described blow-off pipe is provided with sewage draining valve.
Described housing is provided with differential pressure switch.
Operation principle of the present utility model is as follows:
Impure water is entered in filter housings by water inlet, first flows through and carries out coarse filtration into the coarse strainer in water space, filters out the larger particles in water; Then the fie screen of hydrospace of flowing through out carefully filters, and the water purification after filtering is flowed out by delivery port.
The impurity thing filtering out is adsorbed on fie screen, and along with the long-play of filter, filter screen surfaces externally and internally mineralization pressure is poor, when pressure differential reaches setting value, differential pressure switch starts, and cleans motor driving rotating shaft and rotates, further drive cleaning brush running, filter screen is cleaned; Open the sewage draining valve on blow-off pipe simultaneously, with the sewage of impurity, from blow-off pipe, discharge.
The beneficial effects of the utility model are:
By coarse strainer being set in filter water inlet, at water outlet, fie screen is set, abundant impurity in filtered water, and can not stop up filter screen, and can automatically clean filter screen, reduce the replacing number of times of filter screen, save use cost.
In addition, by adopting spirality cleaning brush to substitute rod-type brush board, make the contact of cleaning brush and filter screen stronger, cleansing power is better; Spiral cleaning brush has good guide functions simultaneously; Brush board tangent line and rotating shaft are miter angle, can avoid the jam of brush board, reduce the running resistance while cleaning; Whole filter screen inwall is stressed more even when being cleaned, and frayed degree is also named balanced.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of large flow self-cleaning filter described in the utility model;
In figure:
1, blow-off pipe, 2, fie screen, 3, cleaning brush, 4, differential pressure switch, 5, coarse strainer, 6, housing, 7, water inlet, 8, dividing plate, 9, delivery port, 10, clean motor, 11, sewage draining valve.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment is as shown in Figure 1 known, and a kind of large flow self-cleaning filter described in the utility model, comprising: housing 6, be positioned at water inlet 7, delivery port 9 on housing 6, and the dividing plate 8 and the self-cleaning mechanism that are positioned at housing 6; Dividing plate 8 is divided into the space in housing 6 into He Chu hydrospace, water space; Water inlet is provided with coarse strainer 5 in space, goes out and in hydrospace, is provided with fie screen 2; Self-cleaning mechanism comprises cleaning motor 10, rotating shaft 12 and cleaning brush 3, and rotating shaft 12 is connected with the output that cleans motor 10, and cleaning brush 3 is spirality.
Described cleaning brush 3 be take the axis of rotating shaft 12 and is fixedly connected with rotating shaft 12 as pivot and by a plurality of connecting rods.The brush board tangent line of cleaning brush 3 and rotating shaft 12 be miter angle.
The described housing 6 that goes out hydrospace is provided with blow-off pipe 1, and described blow-off pipe 1 is provided with sewage draining valve 11.
Described housing 6 is provided with differential pressure switch 4, and differential pressure switch 4 connects water inlet He Chu hydrospace, space, and produces control action to cleaning the sewage draining valve 11 of motor 10 and blow-off pipe 1.
The course of work and the operation principle of above-mentioned large flow self-cleaning filter are as follows:
Impure water is entered in filter housings 6 by water inlet 7, first flows through and carries out coarse filtration into the coarse strainer 5 in water space, filters out the larger particles in water; Then the fie screen 2 of hydrospace of flowing through out carefully filters, and the water purification after filtering is flowed out by delivery port 9.
The impurity thing filtering out is adsorbed on fie screen 2, and along with the long-play of filter, filter screen surfaces externally and internally mineralization pressure is poor, when pressure differential reaches setting value, differential pressure switch 4 starts, and cleans motor 10 and drives rotating shaft 12 to rotate, further drive cleaning brush 3 runnings, filter screen is cleaned; Open the sewage draining valve 11 on blow-off pipe 1 simultaneously, with the sewage of impurity, from blow-off pipe 1, discharge.
