Abstract

The utility model discloses a multistage filter which comprises a water inlet tube connected with a water source, a primary filter, a plurality of secondary filters mutually connected in parallel and a water outlet tube, wherein the water inlet end of the primary filter is connected with the water inlet tube, the water inlet ends of the secondary filters are connected to the water outlet end of the primary filter, and the water outlet ends of the secondary filters are connected to the water outlet tube. According to the multistage filter disclosed by the utility model, the cleaning period of almost filters is shortened, the maintenance cost is lowered, and the multistage filter is convenient to clean.

Description

A kind of multistage filter
Technical field
The utility model relates to a kind of multistage filter.
Background technology
Irrigation system is widely used in agricultural, and wherein, because the water dropper water hole in the drip irrigation mode is little, to the water quality requirement height, the functional effect of fore filter is with regard to particular importance.Existing fore filter as shown in Figure 1, generally adopts the combination filter of a plurality of filter 1 parallel connections.But the combination filter of this kind mode, used a period of time after, need to be serviced when cleaning, all filters 1 all need be removed and clean troublesome maintenance and cost height.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of multistage filter is provided, and by multistage filter is set, reduces the cleaning frequency of most of filter, reduces maintenance cost, and cleans conveniently.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of multistage filter, comprise water inlet pipe, primary filter, several secondary filter parallel with one another and outlet pipes of being connected to the water source, the water inlet end of described primary filter is connected to water inlet pipe, the water inlet end of described several secondary filter all is connected to the water side of described primary filter, and the water side of described secondary filter all is connected to outlet pipe.
In another preferred embodiment, described primary filter and secondary filter are respectively well strainer.
In another preferred embodiment, the equal level of described primary filter and secondary filter is inverted, and the sewage draining exit of described primary filter and secondary filter all arranges down.
In another preferred embodiment, be provided with a passage at described outlet pipe.
In another preferred embodiment, also comprise at least one third level filter, described third level filter is connected between the water side and outlet pipe of described secondary filter.
The beneficial effects of the utility model are that owing to adopted the filter of plural serial stage, every grade of filter comprises a filter or a plurality of shunt filter, prolongs the cleaning frequency of back level filter, reduces maintenance cost; The sewage draining exit of filter only need be opened the lid of sewage draining exit down, and water flowing can be cleaned in blowdown, and is convenient and simple; Increase passage, in order to the air in the discharge line.
Below in conjunction with drawings and Examples the utility model is described in further detail; But a kind of multistage filter of the present utility model is not limited to embodiment.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is the structural representation of embodiment one of the present utility model;
Fig. 3 is the structural representation of the primary filter of embodiment one of the present utility model;
Fig. 4 is the structural representation of embodiment two of the present utility model.
The specific embodiment
Embodiment one, referring to Fig. 2 and shown in Figure 3, a kind of multistage filter of the present utility model, comprise water inlet pipe 2, primary filter 3, several secondary filter parallel with one another 4 and outlet pipe 5, the water inlet end of described primary filter 3 is connected to the water source by water inlet pipe 2, the water inlet end of described several secondary filter 4 all is connected to the water side of described primary filter 3, and the water side of described secondary filter 4 all is connected to outlet pipe 5.
Described primary filter 3 and secondary filter 4 are respectively well strainer, but not as limit, other filters such as sandrock filter all can.
In the present embodiment, described primary filter 3 and secondary filter 4 equal levels are inverted, and the sewage draining exit 31 of described primary filter 3 down, and the sewage draining exit 41 of described secondary filter 4 down.
Be provided with a passage 51 at described outlet pipe 5, in order to the air in the discharge line.
Embodiment two, for increasing water quality, can also increase third level filter 6, and described third level filter 6 is connected between the water side and outlet pipe 5 of described secondary filter 4.
Certainly, third level filter also can be that a plurality of filters are connected in parallel.
Certainly, fourth stage filter, level V filter etc. can also be arranged.
The utility model is by adopting the filter of plural serial stage, every grade of filter can be a filter, also can be a plurality of filters that are in parallel, prolong the cleaning frequency of back level filter, reduce maintenance cost, in the actual production, it is just passable that No. three primary filters 3 of every cleaning clean a secondary filter 4 again, and inorganic impurity major parts such as the mud in the water are deposited in the primary filter 3; The sewage draining exit 31 of primary filter 3 and the sewage draining exit 41 of secondary filter 4 are arranged down, only need open the lid of sewage draining exit 31 or sewage draining exit 41, carry out water flowing and can blowdown clean, convenient and simple.
Above-described embodiment only is used for further specifying a kind of multistage filter of the present utility model; but the utility model is not limited to embodiment; every foundation technical spirit of the present utility model all falls in the protection domain of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
