Description
Technical field
The present invention relates to micro water irrigation technical field, and in particular to a kind of hydroturbine used with micro water irrigation system support
Drive self-cleaning net type filter.
Background technology
In recent years, because slight irrigation has many advantages, such as water saving, irrigation uniformity height, saving of labor, section fertilizer, volume increase, development is fast
Speed, it is widely used, it has also become the important technical in agricultural production, current national slight irrigation application area have reached
More than 5000 ten thousand mu.
Slight irrigation mainly includes two kinds of forms of drip irrigation and microspray irrigation, is with being arranged on afterbody (final stage pipeline by pipe-line system
On) special douche (water dropper, mini sprinkler, infiltrating irrigation pipe and micro-pipe etc.), water and nutrient are transported to crop with less flow
Root, make soil conservation optimal water, fertilizer, gaseity irrigation method.Water dropper and mini sprinkler are the cores in irrigation system
Part, but their current aperture all very littles, generally 0.5~2.0mm, are easily blocked by impurities in water, it is therefore desirable to irrigating
Water source carries out strict filtration treatment.
Filter plant has the types such as centrifugation, sandstone, lamination and net formula at present, filters different type and water quality alone or in combination
Water source.Well strainer due to precision it is high, simple in construction the characteristics of, used as afterbody filter.Net formula mistake
The filter mesh size of filter is usually the 1/10 of douche channel size, i.e. 0.05~0.2mm, so being particularly easy to block.
Filter differential pressures are caused to increase after blocking, the flow of water diminishes, and influences the normal use of irrigation system, now must be to filtering
Device is cleaned.Manual-cleaning filter needs to stop irrigation system operation, opens filter, cleans filter screen, then after installing
Ability normal use, normal conditions are at least cleaned 1 time, need to be cleaned 4-5 times daily when water quality is poor, have a strong impact on slight irrigation daily
The normal use of system.So the appearance of automatic cleaning screen filter solves this problem.Self-cleaning mode is main at present
There are two kinds, one kind is that motor driving is brush, and one kind is hydro powered suction type.
Motor driving brush type filter needs to configure motor, decelerator, and complicated, cost is high, and reliability is low, Er Qiexu
220V or 380V power supplys are wanted, in-convenience in use.Hydro powered suction type filter is removed on filter screen using suction type element kit
Impurity, structure is more complicated, and filter effect needs further to be improved, and scavenging period is longer, and the price of element kit is more high
It is expensive, once damage, changes trouble.
Chinese patent CN104740924B discloses a kind of hydroturbine and promotes Microfilter, although it also uses eddies of water wheel portion
Part, but principle and structure are extremely complex, and effect is also undesirable：Needed when it is used " it is suspended in the raw water to be filtered of certain capacity,
Make waterline between cleaning pipe and the axis of filtering net part ", floating drum is also add, normal micro-irrigation filter is not placed
Yu Shuizhong, particularly well water can not be put into water when irrigating, and placement location requires higher, and actual use is limited；" drainage goes out
Mouth is connected with the entrance of water pump ", after general filter is positioned over exit of pump, increases flow using the outlet pressure of water pump, put
Greatly reduce in pump entrance filtering traffic, can also influence the performance of water pump；Using driving wheel, driven pulley and chain drive, knot
Structure is complicated, and efficiency is low；Filter screen is cleaned using shower nozzle spray mode, the impurity being wrapped on filter screen is difficult to clean up, cleaning effect
Fruit is undesirable.
In summary, existing self-cleaning net type filter is primarily present the problems such as complicated, cost is high, reliability is low.
The content of the invention
To solve the technical problem that the cleaning device of current filter is complicated, reliability is low, the present invention provides a kind of
Eddies of water wheel drive self-cleaning net type filter.

- 10. the control method of eddies of water wheel drive self-cleaning net type filter according to claim 8, it is characterised in that：When Between control methods be：When the time interval for reaching setting, pressure regulation motor-driven valve is adjusted, water pressure sensor pressure value is used and is more than necessarily Value, while start cleaning motor-driven valve, water flows through hydroturbine, percussion lower band moving axis and cleaning brush of the eddies of water impeller blade in water Rotation, washes down the impurity on filter screen, and is discharged from drainpipe, when pressure difference value is less than setting value, closes cleaning electricity Dynamic valve, regulation pressure regulation motor-driven valve to normal condition stop cleaning, and filter enters normal operating conditions；Can possess simultaneously manually Cleaning function, when pressing cancel key, system necessarily enters cleaning state, when pressing stop key, into normal filtration state.
