Description
Technical field
The utility model relates to the filter in a kind of agricultural water-saving irrigation equipment, relates in particular to a kind of centrifugal network formula modular filter device.
Background technology
Along with the modern agriculture water-saving irrigation technique develops rapidly, the drip irrigation and spray irrigation technology is just used more and more widely.At present, with the filter of the supporting application of drip irrigation and spray irrigation, be divided into four kinds: centrifugal, sandstone formula, net formula, stacked by filter medium.And according to the water quality difference, need sometimes altogether the filter set of several structures, form two-stage, the filtration more than three grades, so as to realize precisely, high efficiency filter, guarantee the irrigation system clean water quality, douche is not blocked.
At present, when well water water source sand content is high, generally adopt single well strainer to handle, but this structure plays filtration effectively to the sandstone in the water, influence the water amount of system but screen pack is blocked often.At above we develop the combination filter of the manual backwash of this centrifugal network formula.Can play the duration of congestion that effectively and reliably filters and reduce well strainer to sandstone, thus the least possible inflow-rate of water turbine that influences system.
The utility model content
Technical problem to be solved in the utility model provides the centrifugal network formula modular filter device that the high well water water source of a kind of easy and simple to handle, easy to maintenance, suitable silt content filters.
For addressing the above problem, a kind of centrifugal network formula modular filter device described in the utility model is characterized in that: this device comprises sand tank, centrifugal filter and the net formula filtering bodies of being made up of five networking formula filters; Described centrifugal filter bottom links to each other with the top of described sand tank, and its top is connected with U type tube connector, and its top one side is provided with water inlet pipe, and this water inlet pipe is provided with the Pressure gauge of band Pressure gauge separator tube; Another mouth of pipe of described U type tube connector is connected with the filtering bodies water inlet and is responsible for, and its pipe bent position is provided with air bleeding valve; Described filtering bodies water inlet is responsible for by net formula backwash control valve and is linked to each other with described net formula filtering bodies; The bottom of described net formula filtering bodies is connected with the filtering bodies water outlet and is responsible for, and the one side lower part is provided with the sewage draining exit that is connected with the blowdown pressure-relief valve.
Described U type tube connector is provided with fertilising control valve and fertilising valve.
Described net formula filtering bodies water inlet is responsible for and is provided with support.
The utility model compared with prior art has the following advantages:
1,, therefore can realize filtration to the high well water water source of sand content because the utility model adopts centrifugal and net formula double filtration; By the order number of filter screen is set, make the overcurrent precision reach demand simultaneously; By the unit well strainer of parallel connection, make that the filtered water of filtering composite set is used for irrigating, control area can reach 500～600 mu.
2, because the utility model is provided with the hand control valve body, according to drainage impurity situation, can manually control anti-cleaning at any time, water requirement is few during cleaning, and speed is fast, and the dictyosome of several parallel connections can clean by turns, guarantees normal water supply when cleaning.
3, simple in structure, easy to operate, the manageability maintenance of the utility model.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

The specific embodiment
As shown in Figure 1, a kind of centrifugal network formula modular filter device comprises sand tank 1, centrifugal filter 2 and the net formula filtering bodies of being made up of five networking formula filters 14.
U type tube connector 4 is provided with fertilising control valve 8 and fertilising valve 9.
The utility model operation principle: the centrifugal filtration part is removed the solid particle that overweights water based on the operation principle of gravity and centrifugal force.High-velocity flow is entered in the body of centrifugal filter 2 along the tangential direction that enters centrifugal filter 2 by water inlet pipe 3, rotation produces centrifugal force, flow along tube wall by centrifugal action promotion silt and the higher solid particle of density, form eddy flow, bulky grain sandstone, inorganic matter impurity particle are stored in the sand tank 1 of centrifugal filter 2 belows after filtering, in time the foreign material that filter in the sand tank 1 are removed, water purification then following current enters U type tube connector 4 along the upside of centrifugal filter, promptly finish the water sand separation, finally realize the one-level filtration.
The current that filter through centrifugal filter 2 enter second stage---the net formula filtration fraction of filtration by U type tube connector 4.Be full of whole filter space along with current enter whole filtration system, the air bleeding valve 7 above U type tube connector 4 is in time got rid of the air in the whole system, makes filtration system cavitation erosion, vapour lock drop to minimum.Current process U type tube connector 4 backs directly arrive the filtering bodies water inlet person in charge 10 backs and divide five strands of current to enter respectively in five groups of 3 cun well strainers, respectively the current that filter through one-level are carried out cascade filtration.Well strainer mainly carries out impurity such as the grains of sand in the cascade filtration water quality by stainless steel filtering net.
When net formula filtering bodies 14 front and back pressure reduction surpass the pressure reduction of regulation, carry out backwash, manually close the import dish valve of each well strainer during backwash successively, open net formula backwash control valve 12 and carry out the anti-cleaning of net formula filtering bodies 14, also filter screen can be taken out in the net bucket and clean, wash away impurity on the screen wall with clear water and hairbrush.Be pooled to the filtering bodies water outlet through the current after 3 cun well strainers filtrations and be responsible in 15, the water quality of passing through cascade filtration like this can enter the field pipe network system and carry out drip irrigation.
