A kind of centrifugal type cone net Integral filter
Technical field
The present invention relates to a kind of filter, particularly about a kind of centrifugal type cone net Integral filter that is applicable to drip irrigation system.
Background technology
Filter is equipment commonly used in irrigation system, when iirigation water source is underground water, generally take the form of centrifugal type filter and screen cloth or laminated filter combination to filter, after silt in water filters by first order centrifugal type filter, most of silt is eliminated, screen mesh type filter or laminated filter are removed remaining silt in water as second level filter, realize the double filtration effect to irrigation water.This filter type has following shortcoming, and at first, current need to be through two devices, and every one-level filter all causes certain energy loss, and irrigation water has the more pressure loss after filtering; Secondly, two-stage filtration system needs dual stage filter apparatus is connected in the engineering application process, has therefore increased manufacturing cost, has increased simultaneously the floor space of system, has increased construction investment; Have again, the secondary filter assembly of this filtration system is screen mesh type or laminated filter, rely on screen cloth or lamination gap obstruction delay impurity to pass through, want removal of contamination will adopt the mode removal of contamination of backwash, particularly when water quality is relatively poor, need frequent backwash, bring many inconvenience to engineering operation.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide a kind of simple in structure, centrifugal type cone net Integral filter that can carry out lift-off processing impurity under than low water head loss condition
For achieving the above object, the present invention takes following technical scheme: a kind of centrifugal type cone net Integral filter, it is characterized in that: comprise a housing, described housing top is a cylinder chamber, the bottom is a cone bucket, and the sidewall of described cylinder chamber is provided with a water inlet, and the top is provided with a delivery port, the bottom of described delivery port is fixedly connected with a up-small and down-big conical pipe, and the end mouth of described conical pipe is fixedly connected with a taper screen cloth; Be provided with a recessed edge of circle on the described conical pipe of the online side of described conical screen, be arranged with annulus on a stainless steel on described recessed edge, be arranged at intervals with four cleaning brush that extend along described taper screen cloth on described upper annulus downwards, the bottom of each described cleaning brush is connected on the less lower annulus of a diameter, the outlet of described cone bucket is connected with a sand collecting tank by flange, is arranged at intervals with some current stabilization blades on the inwall above described cone bucket outlet.
The shape of described current stabilization blade adopts strip, square, triangle, any one in fan-shaped.
The present invention is owing to taking above technical scheme, and it has the following advantages: 1, filter of the present invention can be realized the husky separative efficiency of higher water under with the condition of equal-pressure-difference and conveyance capacity; When reducing equipment investment and occupation area of equipment, two kinds of filter types are combined together, therefore can realize disposable that the irrigation water filtration is thorough; 2, the present invention is owing to partly being provided with the cleaning brush of peeling off silt at the conical screen net filtration, therefore can realize in the course of the work self-cleaning to a certain degree, therefore can extend the interval time of Filter Back Washing, because the mode that adopts a plurality of filter parallel connections realizes filtration to great deal running water, when adhering to silt on screen cloth than thickness or too tiny can't continue to separate the time, can realize by the mode of backwash the cleaning of screen cloth.3, the present invention owing to realizing double-filtration in a filter, therefore takes up an area equipment little, and fixed investment reduces.Project organization of the present invention is simple and practical, and is cheap, is convenient to make, and can be widely used in agricultural irrigation and use among filtering.

The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention includes a housing, housing top is a cylinder chamber 1, and the bottom is a cone bucket 2.The sidewall of cylinder chamber 1 is provided with a water inlet 3, and the top is provided with a delivery port 4, and the bottom of delivery port 4 is fixedly connected with a up-small and down-big conical pipe 5, and the end mouth of conical pipe 5 is fixedly connected with a taper screen cloth 6(as shown in Figure 3).Be provided with a recessed edge of circle on the conical pipe 5 above taper screen cloth 6, be arranged with on a stainless steel annulus 7(on recessed edge as shown in Figure 4), be arranged at intervals with four cleaning brush 8 along taper screen cloth 6 to downward-extension on upper annulus 7, the bottom of each cleaning brush 8 is connected on the less lower annulus 9 of a diameter (as Fig. 5, shown in Figure 6), the outlet of cone bucket 2 is connected with a sand collecting tank 11 by flange 10, is arranged at intervals with some current stabilization blades 12 on the inwall above 2 outlets of cone bucket.
In above-described embodiment, the shape of current stabilization blade 12 can adopt strip, square, triangle or fan-shaped etc.
When the water inlet 3 that radially arranges from the present invention when the High-Pressure Water that contains silt in system enters cylinder chamber 1, under the effect of centrifugal force, the water that contains silt spirals between conical pipe 5 and cylinder chamber 1 and separates, because contained silt in water has larger proportion, silt can be pressed close to cylinder chamber 1 madial wall and descend while rotating under centrifugal action; Because conical pipe 5 is up-small and down-big, the space between cylinder chamber 1 and conical pipe 5 diminishes gradually, and the rotary speed of current is accelerated, and has promoted the separating effect of silt.When making current keep preferably the Separation of Solid and Liquid state, the silt content of spiraling in the current around conical pipe 5 also can decrease, particularly when current are in conical pipe 5 below, it is large that water flow space becomes suddenly, water velocity slows down rapidly, the ability of carrying silt effectively reduces, and particularly current stabilization blade 12 has the effect that further weakens the current disturbance, and silt is accelerated greatly along the speed that the sidewall of boring bucket 2 finally enters sand collecting tank 11.Water after filtering through taper screen cloth 6 is discharged at delivery port 4 places of cylinder chamber 1.
The present invention is owing to being provided with the upper annulus that connects four cleaning brush 8 in the recessed edge of conical pipe 5, therefore work as current in the mobile process of spiraling, can drive cleaning brush 8 rotates around taper screen cloth 6, silt on taper screen cloth 6 is cleared up at any time, therefore can prevent effectively that silt from adhering to, the current after guaranteeing to separate normally pass through.
In above-described embodiment, if need the water yield of processing silt larger, can adopt the mode of a plurality of parallel connections to realize operation, the filter of two the above different flows of the present invention that namely are connected in parallel.
The various embodiments described above only are used for explanation the present invention, and wherein the structure of each parts, connected mode etc. all can change to some extent, and every equivalents of carrying out on the basis of technical solution of the present invention and improvement all should not got rid of outside protection scope of the present invention.
