Defer to technique scheme, as shown in Figures 1 to 7, a kind of micropore ceramics drip emitter of anti-clogging easy cleaning, comprise pedestal 8, pedestal 8 is removably provided with chamber shell 10, chamber shell 10 inside is provided with cavity 14, infiltration sheet 13 is installed in cavity 14, in infiltration sheet 13, is distributed with hole; Chamber shell 10 is provided with to pass through with cavity 14 and repeatedly kicks into water hole 11, pedestal 8 is provided with the apopore 5 arranged with inlet opening 11 coaxial inner conductor, current flow out pedestal 8 from apopore 5 after inlet opening 11 enters cavity 14 after the filtration of the sheet 13 that seeps water.
Basic structure of the present invention comprises a pedestal 8 and a chamber shell 10, and the inside of its lumen shell 10 is cavity 14, and cavity 14 has multiple effect, and the first is for installing infiltration sheet 13, and its two filter space being to provide current, for slow releasing function is played in the outflow of current.Infiltration sheet 13 in this programme, adopts infiltration sheet 13 structure of porous.Infiltration sheet 13 inside is distributed with multiple hole erratically, and the existence of these holes allows current to pass through in infiltration sheet 13, penetrates into below, play a role in filtering to the impurity in current from the top of infiltration sheet 13.Because hole is wherein more, and distribute in a jumble, this erratic distribution mode, what extend current flows through path, while more thorough, effective removing is carried out to impurity, also make impurity be not easy to block pore channel, improve the actual practical value of irrigator.
The infiltration sheet 13 adopted in the present embodiment is micropore ceramics infiltration sheet 13, its diameter is 30mm, and the margin of tolerance is-0.1 ~-0.2mm, and micropore ceramics infiltration sheet 13 surrounded surface is smooth, with ensure irrigator operationally micropore ceramics infiltration sheet 13 can move freely, do not blocked by pedestal 8.Micropore ceramics infiltration sheet 13 is thin discs structure, can be formed by the micropore ceramics materials processing with micron pore size, and have the duct of the micropore formation be interconnected in a large number in this micropore ceramics infiltration sheet 13, irrigation water can flow in these ducts.Due to frictional force and the capillary force in duct, the flowing velocity of irrigation water in duct is slow, therefore can carry out energy dissipating to having pressure irrigation water.
According to the designed outlet water requirement of irrigator, the porosity of micropore ceramics is 40 ~ 60% adjustable, and in the present embodiment, the porosity of micropore ceramics infiltration sheet 13 is 53%.The even structure of micropore ceramics, does not have defect, and average pore size is 1 ~ 2 micron, the solid impurity in irrigation water can be filtered fully, significantly improves the anti-blocking of irrigator.Between each hole, there is extraordinary connectedness in micropore ceramics infiltration sheet 13, provide sufficient penetrating passage.By test, the bending strength of micropore ceramics infiltration sheet 13 is 30 ~ 50MPa, ensure that the dependability of irrigator and longer service life.
The longitudinal cross-section of chamber shell 10 is in falling " recessed " shape, the inner position near shell 10 top, chamber of chamber shell 10 is configured for along projection symmetrical near the direction of inlet opening 11 axis the limiting card 2 limiting infiltration sheet 13 position, the top of described infiltration sheet 13 is positioned at the below of limiting card 2, forms intake antrum 12 thus between the top and inlet opening 11 of infiltration sheet 13.
Limiting card 2 be one around the endless loop be arranged on chamber shell 10 inwall, after limiting card 2 is arranged, infiltration sheet 13 just can not directly get lodged in below inlet opening 11, so just below inlet opening 11, leave an intake antrum 12 all the time, intake antrum 12 can disperse to enter the current in cavity 14 effectively, play cushioning effect, ensure that infiltration sheet 13 has larger initial infiltration area, current to enter after in cavity 14 can be different on infiltration sheet 13 position through infiltration sheet 13, play effective filtration on the one hand, also water yield is kept constant on the other hand and play buffering facilitation.
The effect being provided with the first sealing ring 3, first sealing ring 3 between the infiltration top of sheet 13 and limiting card 2 is that shutoff seep water the edge of sheet 13, and it adopts elastomeric material to make, and has certain elasticity, allows the activity among a small circle of infiltration sheet 13.In addition, the first sealing ring 3 also plays the effect of fixing infiltration sheet 13.
Pedestal 8 top is provided with along the circumference of pedestal 8 land 9 that external diameter is less than pedestal 8, and described infiltration sheet 13 is positioned at above land 9, jointly forms water chamber 15 bottom infiltration sheet 13 with the part in land 9.Pedestal 8 is polyethylene material, adopts injection molding process to make.Land 9 on pedestal 8 has multiple effect, first, land 9 is for being raised in the structure on base, and land 9 defines a space in inside thus, this space forms water chamber 15, for cushioning effect is played in the outflow of filtering rear current jointly with the space below infiltration sheet 13; Secondly, the outer wall of land 9 is provided with external screw thread, the inwall of chamber shell 10 is provided with internal thread; The external diameter of chamber shell 10 is consistent with the external diameter of land 9; The mode be threaded connection, can facilitate the dismounting between pedestal 8 and chamber shell 10, is convenient to cleaning and the replacing of inner infiltration sheet 13; 3rd, the top of land 9 is used for installing fixing infiltration sheet 13.Due to the sheet 13 that seeps water position needs above it, below all reserves certain space, the sheet 13 that therefore seeps water preferably is fixed on the medium position in cavity 14.The setting of land 9 solves this problem, and its top is provided with the second sealing ring 4, and infiltration sheet 13 is clamped and fixed between the first sealing ring 3 and the second sealing ring 4.Two sealing rings serve effective fixing to infiltration sheet 13, carried out effective sealing to the edge of infiltration sheet 13 simultaneously.Second infiltration sheet 13 also can adopt elastomeric material to make, and slightly can be out of shape under the pressure effect of the infiltration sheet 13 of current.
Except this installation fixed form of the first sealing ring 3, second sealing ring 4, another optional scheme is, as shown in Figure 5, infiltration sheet 13 bottom and be provided with elastic pressure compensate gasket between pedestal 8, pressure compensation pad is infundibulate, and be the through hole of reducing in the middle part of it, the top of pressure compensation pad is valgoid, the internal diameter of bottom reaches unanimity gradually, and the bottom of pressure compensation pad is docked with apopore 5.
In this kind of scheme, utilize pressure compensation pad to substituted for the second infiltration sheet 13, namely pressure compensation pad is just supported on infiltration sheet 13.Infiltration sheet 13 elasticity is good, such as, adopt silica gel material to make.Its top is eversion type structure, and under the effect of the pressure, the top of pressure compensation pad partly can be attached at the bottom of infiltration sheet 13, thus reduces the infiltration area bottom infiltration sheet 13, thus controls flow.Pressure compensation pad entirety is similar to infundibulate, and the internal diameter bottom it is basically identical, and current from intake antrum 12, then enter into pressure compensation pad, pass through from its diameter bore after infiltration sheet 13, finally flow out from apopore 5.
The effect of pressure compensation pad is, 1. when the intake pressure of irrigator is less, although the flow velocity of irrigation water in micropore ceramics infiltration sheet 13 is slower, but because micropore ceramics infiltration sheet 13 upper and lower pressure reduction is less, the pressure that pressure compensation pad is subject to micropore ceramics infiltration sheet 13 is less, be out of shape less, less with the contact area of pressure compensation pad below micropore ceramics infiltration sheet 13, the infiltration area of irrigation water is larger; 2. when the intake pressure of irrigator increases, the flow velocity of irrigation water in micropore ceramics infiltration sheet 13 accelerates, but the sheet 13 of micropore ceramics infiltration simultaneously upper and lower pressure reduction increases, the pressure that pressure compensation pad is subject to micropore ceramics infiltration sheet 13 becomes large, distortion increases, increase with the contact area of elastomeric pad below micropore ceramics infiltration sheet 13, the infiltration area of irrigation water reduces, thus when ensure that pressure increase, the water yield of irrigator is constant; 3., when the intake pressure of irrigator reduces, above-mentioned all changes are reversed, and still can ensure that the water yield of irrigator is constant.Thus, by the effect of pressure compensation pad, the water yield of irrigator under different water pressures can be consistent substantially.
As shown in Figure 1, the top of chamber shell 10 is provided with the first link 1, the bottom of pedestal 8 is provided with the second link 6, described inlet opening 11 is from axial penetration first link 1, described apopore 5 is from axial penetration second link 6, the outer wall of the first link 1 and the second link 6 is provided with connector, and the axial cross section of connector is trapezoidal.The structure of this fluking type, can ensure that hollow billet inserts rear and irrigator compact siro spinning technology.The maximum outside diameter of the first link 1 is 4mm, and overall length is 12mm, and the internal diameter of inlet opening 11 is 2mm, this set make irrigator operationally water inlet be regions of turbulent flow, reduce the probability that impurity enters irrigator, improve the resistance against physical blocking ability of irrigator.
The edge of pedestal 8 and chamber shell 10 is all provided with tangent plane 7, erases by pedestal 8 and the sharp keen edge of chamber shell 10, make edge be obtuse angle transition, be convenient to attended operation.
Pedestal 8 and chamber shell 10 when mounted, according to the signal of accompanying drawing 1, are first turned on, are put into the first sealing ring 3 by this programme, then put into infiltration sheet 13 and the second sealing ring 4, and then pedestal 8 and chamber shell 10 are tightened, dismounting is very convenient.During irrigator work, ducted have pressure irrigation water first to enter in the intake antrum 12 on irrigator top by the inlet opening 11 of irrigator, then oozes out downwards via micropore ceramics infiltration sheet 13, collect, finally flowed out by apopore 5 at the bottom water chamber 15 of irrigator.
See accompanying drawing 6, when the water quality of irrigation water is better, irrigation water to be full of above micropore ceramics infiltration sheet 13 while intake antrum 12, the duct that can be interconnected along micropore ceramics infiltration sheet 13 inside is oozed out downwards, flow out, as shown in Fig. 6 (a) finally by by the delivery port below irrigator.When the water quality of irrigation water is poor, due to the particle diameter of aperture most impurity in irrigation water of micropore ceramics infiltration sheet 13 inside, therefore micropore ceramics infiltration sheet 13 can by surperficial thereon for the most of contaminant filters in irrigation water, filtered irrigation water can ooze downwards along the micropore ceramics sheet 13 that seeps water subsequently, only has the small particle diameter impurity of seldom amount can enter micropore ceramics infiltration sheet 13 inner in irrigation water.Along with the increase of irrigator service time, the small particle diameter impurity in irrigation water can slowly deposit in micropore ceramics infiltration sheet 13 top intake antrum 12, causes the water yield of irrigator to reduce gradually, as shown in Fig. 6 (b).When irrigator blocking is serious, water yield cannot meet irrigation when requiring, irrigator is taken off upside-down mounting to continue to use on hollow billet, the upper and lower surface of now micropore ceramics infiltration sheet 13 exchanges, the large granular impurity of micropore ceramics infiltration sheet 13 lower surface can be taken out of irrigator by current, and by strengthening ducted hydraulic pressure, the granule impurity of alluvial in micropore ceramics infiltration duct, sheet 13 bottom can be gone out, complete the flushing of irrigator, as shown in Fig. 6 (c).By the design of this structure, make irrigator internal washing very convenient, enhance the actual use value of irrigator.
See accompanying drawing 7 (a), test with household tap water, the flow of micropore ceramics drip emitter under 3m and 5m head of the anti-clogging easy cleaning of the present embodiment is respectively 4.0L/h and 7.1L/h, irrigator running hours, remains unchanged after its stability of flow.
In order to verify the self-cleaning effect of the micropore ceramics drip emitter of anti-clogging easy cleaning of the present invention.After being adopted by irrigator the silt water of high concentration to block completely, upside-down mounting, on hollow billet, then tests the water yield change of irrigator under different hydraulic pressure.See accompanying drawing 7 (b), first adopt the hydraulic pressure of 5m, the water yield of irrigator slowly increases along with the increase of time, and this illustrates that the impurity being previously blocked in micropore ceramics infiltration sheet 13 surface is slowly rinsed out.When the time reaches 9 minutes, the water yield of irrigator reaches 6.6L/h, has substantially returned to its normal water yield.When turning down hydraulic pressure to 3m, the water yield of irrigator is 3.8L/h, basically identical with the normal water yield of irrigator again, and along with the increase of time, the water yield of irrigator also recovers in continuation.
The micropore ceramics drip emitter of anti-clogging easy cleaning of the present invention, has given full play to micropore ceramics infiltration sheet 13 to having the pressure energy dissipating of irrigation water and the filtration to impurity.This irrigator effectively can reduce the manufacture of irrigator and assembling deviation on the one hand on the impact of irrigator water yield, improves the uniformity of irrigation water appilcation of irrigator, the impurity in irrigation water effectively can be filtered on the other hand, improve the anti-blocking of irrigator.Even if irrigator there occurs blocking, only by irrigator upside-down mounting and hollow billet continuing use, both need complete the self-cleaning of irrigator, not affect again the use of irrigator.In addition, save at slack seasons and the micropore ceramics infiltration sheet 13 in all irrigators is taken out, put into ultrasonic cleaner cleaning 1 ~ 2 minute, micropore ceramics all can be removed by the impurity seeped water in sheet 13, for next time in busy farming season prepares.
