Abstract
Disclosed is a large flow self-cleaning filter. The large flow self-cleaning filter is used for an agricultural irrigation system. The large flow self-cleaning filter comprises a barrel-shaped filter case, a water inlet and a water outlet are arranged on the case, a partition board is disposed in the case, the water inlet and the water outlet are separated to form two space, a coarse filter screen is arranged in the water inlet space, a fine filter screen is disposed in the water outlet space, a cleaning brush is mounted in the fine filter screen space, the cleaning brush is connected with a cleaning motor arranged at one end of the case, and a discharge pipe is arranged on the fine filter screen space case. A differential pressure switch is mounted on the case. The large flow self-cleaning filter has the advantages that the filter filtering screen can be automatically cleaned, impurities in water can be prevented from affecting the system, and the replacement times of filter filtering screen can be reduced.
Description
Technical field
The utility model relates to the used filter of a kind of agricultural irrigation systems.
Background technology
Because contain a large amount of impurity in the water, when crops were irrigated, the impurity in the water very easily caused the obstruction of system, and irrigation is exerted an influence.Impurity is generally installed filter to the impact of irrigation system in pipeline in the water, owing to using not long-time, the filter screen of filter namely gets clogged, and needs often to change, and not only wastes time and energy, and to interrupt appearred in the irrigations of crops, affect the growth of crop.
Summary of the invention
The purpose of this utility model provides a kind of large flow self-cleaning filter; utilize filter screen directly to tackle impurity in the water; remove water body suspension, particle; reduce turbidity; purify water; the generations such as minimizing system dirt, bacterium algae, corrosion are to purify water and other equipment normal operations of protection system.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of large flow self-cleaning filter, comprise the cartridge filter housing, housing is provided with water inlet and delivery port, it is characterized in that: be provided with dividing plate in the housing, water inlet and delivery port are divided into two spaces, be provided with coarse strainer in the water inlet space, be provided with fie screen in the delivery port space, in the fie screen space, be provided with cleaning brush, and be connected with the cleaning motor of housing one end, on the housing of described fie screen space, also be provided with blow-off pipe.
The above housing is provided with differential pressure switch.
The utility model beneficial effect is, automatically realizes the cleaning to strainer screen, avoids in the water impurity on the impact of system, and reduces the replacing of strainer screen.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the 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. cleaning motor; 11 valves.
The specific embodiment
By accompanying drawing 1 as can be known, the utility model comprises cartridge filter housing 6, housing 6 is provided with water inlet 7 and delivery port 9, be provided with dividing plate 8 in the housing 6, water inlet 7 and delivery port 9 are divided into two spaces, be provided with coarse strainer 5 in water inlet 7 spaces, be provided with fie screen 2 in delivery port 9 spaces, in fie screen 2 spaces, be provided with cleaning brush 3, and be connected with the cleaning motor 10 of housing 6 one ends, on described fie screen 2 space housings 6, also be provided with blow-off pipe 1.Simultaneously, be provided with differential pressure switch 4 at the above housing 6, differential pressure switch 4 connects coarse strainer 5 spaces and fie screen 2 spaces, and the valve 11 that cleans motor 10 and blow-off pipe 1 is produced control action.
Operation principle of the present utility model is, impure water enters filter by water inlet 7, and the coarse strainer 5 of flowing through first carries out coarse filtration, then enters fie screen 2 inner chambers and carefully filters, and the water purification after the filtration is flowed out by delivery port 9.Therefore the impurity absorption that filters out and has formed the pressure reduction of filter screen surfaces externally and internally on fie screen 2.When pressure reduction reached setting value, differential pressure switch 4 started, and cleaned motor 10 and drove cleaning brush 3 runnings, and fie screen 2 is cleaned, and opened simultaneously the valve 11 on the blow-off pipe 1, discharged from blow-off pipe 1 with the sewage of impurity.
Should be noted that embodiment described in the utility model only is its optimal way, only is apparent change to belonging to technical solutions of the utility model, all should belong within the protection domain of the present utility model.
