Abstract
The invention relates to the technical field of agriculture irrigation, and particularly discloses a low-voltage self-cleaning net-type continuous filter. At present, filters for cleaning filter screens mainly comprise a back washing type filter and a self-cleaning type filter according to an agriculture irrigation technology, wherein the back washing type filter requires the high water pressure in a back washing process, the cost and the energy consumption are greatly improved, and a cleaning effect is not ideal; and according to the other self cleaning type filter, two phases, namely, a filtering stage and a cleaning stage, are needed in work, the disadvantage of the short work cycle is caused, and the cleaning efficiency is low. The low-voltage self-cleaning net-type continuous filter provided by the invention comprises a shell, wherein the shell is provided with a water inlet and a water outlet, an inner cavity of the shell is provided with a barrel-shaped filter screen and is driven by a driving device; the barrel-shaped filter screen is assembled with an end cover through a ball bearing, the inner side of the end cover is fixedly provided with two upper baffle plates, and a position of the lower part of the inner cavity of the shell, corresponding to the upper baffle plates, is fixedly provided with two lower baffle plates which are same as the two baffle plates; and the lower baffle plates are provided with brush bodies, the brush bodies cling to the surface of the filter screen, and gaps are arranged between the edges of the baffle plates and the inner cavity of the shell.
Description
Technical field
The present invention relates to agricultural irrigation technology, specifically a kind of low pressure self-cleaning net formula continuous filter.
Background technology
At present, in the agricultural irrigation technology, the filter of filter screen capable of washing mainly contains two types, and a kind of is back flush type; Another kind is to wash the net formula automatically.
The operation principle of back flush type filter is to realize remaining impurities on the filter screen is cleared up by changing the direction of a stream of water, though this backwashing manner can be realized the self-cleaning to filter screen, but effect is bad, and a lot of intractable impurity still can remain on the filter screen, influence filter effect.In addition, the hydraulic pressure that backwash process is had relatively high expectations has improved cost and energy consumption greatly.Influence filter effect.This is a kind of working method of interval simultaneously.
At present, washing well strainer automatically all is to clean by brush and filter screen friction when cleaning filter screen, need be divided into two stages when still working, and namely filtration stage and wash phase are a kind of working method of interval equally, and the filtration work period shortens.Except above shortcoming, in brush brush filter screen process, because the hydraulic pressure effect, cleaning performance is also also bad.
Summary of the invention
The objective of the invention is to want to provide a kind of low pressure self-cleaning net formula continuous filter, to overcome the defective that prior art exists, realize uninterrupted the filtration and self-cleaning.
Technical scheme of the present invention is to comprise housing; Formed by barrel strainer, power transmission shaft, bearing, the assorted jar of storage, overhead gage, lower baffle plate, brush body; Housing one end top is provided with water inlet, and rear end cap is provided with delivery port; The housing below is provided with impurity discharging port, and the opening part of impurity discharging port is provided with assorted jar of storage, and the assorted jar of storage is provided with sewage draining exit; Power transmission shaft is contained on the housing drive end bearing bracket by bearing, and barrel strainer is housed on the power transmission shaft, and power transmission shaft is connected with motor on being fixed on support arm; Assemble by ball bearing between barrel strainer and the barrel strainer end cap, two overhead gages are fixedly arranged on the barrel strainer end cap inboard, two lower baffle plates are fixedly arranged on the bottom of housing inner chamber and the overhead gage opposite position, brush body is housed on the lower baffle plate, brush body and screen surface are close to; Be provided with the gap between the edge of dividing plate and the housing inner chamber.
Further, the cross section between described two overhead gages is fan-shaped.
Advantage of the present invention is simple in structure, and cost is lower, and the barrel strainer bottom is in the less zone of pressure, is conducive to brush body cleaning impurity, and the pressure reduction of the pressure reduction of filter intake-outlet and filter intake-outlet of the prior art is less; Cleaning performance is good, and low, the convenient later maintenance of cost has the advantages that to realize continuous filtration and cleaning.
Description of drawings
Fig. 1 is external structure schematic diagram of the present invention;
Fig. 2 is the axial cutaway view of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Among the figure: 1 delivery port, 2. rear end cap, 3. drive end bearing bracket, 4. water inlet, 5. power transmission shaft, 6. bearing, 7. housing, 8. storage is assorted jar, 9. barrel strainer, 10. overhead gage, 11. lower baffle plates, 12. brush bodies, 13. barrel strainer end caps.
From Fig. 1, Fig. 2, Fig. 3 as can be known, comprise housing; Formed by barrel strainer 9, power transmission shaft 5, bearing 6, assorted jar 8 of storage, overhead gage 10, lower baffle plate 11, brush body 12; Housing one end top is provided with water inlet 4, and rear end cap 2 is provided with delivery port 1; Housing 7 belows are provided with impurity discharging port, and the opening part of impurity discharging port is provided with assorted jar 8 of storage, and storage is provided with sewage draining exit for assorted jar 8; Power transmission shaft 5 is contained on the housing drive end bearing bracket 3 by bearing 6, and barrel strainer 9 is housed on the power transmission shaft 5, and power transmission shaft 5 is connected with motor on being fixed on support arm; Assemble by ball bearing between barrel strainer 9 and the barrel strainer end cap 13, barrel strainer end cap 13 inboard going up fixedly have two overhead gages 10, cross section between two overhead gages 10 is fan-shaped, on the bottom of housing inner chamber and overhead gage 10 opposite positions two lower baffle plates 11 are arranged fixedly, brush body 12 is housed on the lower baffle plate 11, and brush body 12 is close to screen surface; Be provided with the gap between the edge of baffle plate and the housing inner chamber; The bottom of barrel strainer 9 is in the less zone of pressure.
When the present invention worked, when certain some of barrel strainer was positioned at housing bottom, brush body all once cleaned the filter screen at this position, because the pressure in this zone is less, water velocity is static relatively, the brush body 12 on the baffle plate can easily clean filter screen.Cleaned the impurity discharging port of impurity through the housing below that gets off by brush body and enter in the assorted jar 8 of storage, and emit by the sewage draining exit of storing on assorted jar 8.
Obviously, the above embodiment of the present invention only is for example of the present invention clearly is described, and is not to be restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that apparent variation that technical scheme of the present invention extends out or change still are in protection scope of the present invention.
