Self-cleaning eddy flow combined precision sand cleaning machine
Technical field
The present invention relates to a kind of sand cleaning machine, particularly a kind of self-cleaning eddy flow combined precision sand cleaning machine, is mainly used in the filtration of underground waterway.
Background technology
Current domestic liquid cyclone sand cleaning machine is the solid particle removed and overweight water, and solid particle proportion being less than to water then directly enters system with liquid, cannot directly remove; Simultaneously when the flow instability rotated and power are for time disorderly with the current stopping moment, solid particle also cannot be removed.Below illustrate two kinds of filters that remove sand conventional in prior art:
The existing underground water filter that removes sand mostly is separate assembling, primary structure is see Fig. 2, it to remove sand the structural representation of filter+filter for existing eddy flow, it mainly comprises: eddy flow removes sand filter 201, system of connections 202 and filter 203, and the described eddy flow filter 201 that removes sand is connected by system of connections 202 with filter 203.Cyclone desander water inlet 204 and cyclone desander delivery port 205 is provided with on eddy flow removes sand filter 201, when current remove sand after filter 201 from cyclone desander water inlet 204 tangentially to enter eddy flow under a certain pressure, produce strong rotary motion, because sand is different from water density, under the effect of centrifugal force, centripetal force, buoyancy and fluid knockout press, make low density liter waterborne, the sand that density is large is separated to be deposited in sand collecting cavity, and the water after process upwards enters system of connections 202 through delivery port along water outlet mozzle.System of connections 202 is generally inverted U structure, and to remove sand filter 201 and filter 203 for connecting eddy flow, its Main Function is water conservancy diversion.Under the pressure effect of current, water enters filter 203 through mozzle, and still containing the less grains of sand of particle and the lighter material of proportion in water now, therefore, for requiring higher water treatment efficiency, filter 203 is very necessary.Filter 203 is different according to filtering accuracy, and be fixed on skeleton by the screen cloth of different accuracy, water, by being retained by the material being greater than filter screen hole during screen cloth, both completed filtration duty.In normal operation, in water after eddy flow removes sand filter 201 process, the remaining grains of sand and impurity can be trapped within filter 203 influent side, along with the increase that impurity retains, filter 203 can reduce filter efficiency because of the minimizing in water hole hole.When hole blocks completely, filter 203 both lost filter capacity, filter screen can be crushed, cause damage under the effect of hydraulic pressure.Therefore, filter will often clean, to ensure filter efficiency and device security.Fig. 2 major defect will extract out the filter core of filter screen to clean, and to ensure its filter capacity, because its structure does not simply possess self-cleaning ability, needing to stop pump working, reducing operating efficiency when cleaning, very inconvenient.
