Description
Technical field
The utility model belongs to a kind of slight irrigation filter, particularly a kind of centrifugal screen cloth integral type slight irrigation filter.
Background technology
The purification of water quality filter plant that is applied to the agricultural water-saving irrigation technical field at present is more, be applicable to that wherein the filter plant that contains sand water quality is mainly centrifugal screen cloth combined filter, centrifugal filter and granular membrane are separate in some centrifugal screen cloth combined filter, rely on the pipeline that connects both to form the cascade filtration system of combination during operation, its structure is formed complexity, hydraulic loss is big, cost is high, floor space is big, it is equal inconvenient to dismantle, transport and install, and has limited the popularization and application of micro irrigation technology to a certain extent.It is a kind of centrifugal water treatment filter of ZL01204590.X that Chinese patent discloses the patent No., though the as a whole structure in its centrifugal chamber and mud chamber, but its centrifugal chamber and Sha Shui separation cone have just solved the load-bearing problem of sand water separation cone still for working respectively, and filter effect is unsatisfactory.
Summary of the invention
The utility model is bad at the filter effect that centrifugal screen cloth combined filter in the prior art exists, and complex structure and other problems provides a kind of centrifugal screen cloth integral type slight irrigation filter.
The technical scheme that the utility model adopted: centrifugal screen cloth integral type slight irrigation filter, comprise water inlet pipe, outlet pipe, manometer, centrifugal chamber, sand storage chamber, all adopt welded steel plate to form.Water inlet pipe side direction tangent line enters the centrifugal chamber top, and the top cover below on centrifugal chamber top is equipped with eddy flow and is quickened isolating cylinder, does the eddy flow circular motion that quickens isolating cylinder around eddy flow in the runner of water between eddy flow acceleration isolating cylinder and centrifugal chamber.Eddy flow quickens in the isolating cylinder turbination screen cloth to be housed, and rhombus iron bar and steel skeleton are housed in the turbination screen cloth, and turbination screen cloth upper end links to each other with top cover, and the lower end is connected with outlet pipe.Sand storage chamber is positioned at the centrifugal chamber below, and be connected as a single entity with centrifugal chamber, sand storage chamber's diameter is greater than the centrifugal chamber diameter, and the bottom is provided with sand removing hole and flushing valve, sand removing hole is provided with the blowdown control device that gland, spinning roller, cross-arm and rubber blanket are formed, and flushing valve is located at the opposite of sand removing hole.Top cover central authorities are provided with the automatic air intake and discharge valve, satisfy the intake and exhaust needs that centrifugal chamber in service may occur.
The beneficial effects of the utility model: 1, good filtration effect, hydraulic loss is low; 2, structure simple structure, cheap is convenient to transportation and is installed.

Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further, present embodiment is to be used for illustrating of the present utility model, rather than the utility model is done any restriction.
The utility model all adopts welded steel plate to form, and water inlet pipe 1 is positioned at centrifugal chamber 6 tops, and enters centrifugal chamber 6 by the side direction tangent line, and top cover 3 belows on centrifugal chamber 6 tops are equipped with eddy flow and are quickened isolating cylinder 5.Top cover 3 and centrifugal chamber 6 adopts flanges to be connected, between use rubber seal.Eddy flow quickens to be provided with a stainless steel turbination screen cloth 7 in the isolating cylinder 5, covers in outside the rhombus iron bar 8, and 9 of steel skeletons are positioned within the iron bar 8.All adopt rubber seal between turbination screen cloth 7 and the top cover on it 3 and the lower discharging tube 10 thereof.Sand storage chamber 11 is positioned at the bottom of centrifugal chamber 6, and slightly larger in diameter is in the diameter of centrifugal chamber 6, and its sidepiece sand removing hole 12 is provided with the blowdown control device that gland 13, spinning roller 14, cross-arm 15 and rubber blanket are formed, and is provided with a flushing valve 18 at sand removing hole 12 back to face.Outlet pipe 10 is positioned on the axial location of centrifugal chamber 6 and passes sand storage chamber's 11 base plates.On inlet tube and outlet tube, be provided with manometer 2,16.For satisfying the intake and exhaust needs that centrifugal chamber 6 in service may occur, be provided with an air inlet and exhaust valve 4 at the top, center of top cover 3.Whole filter uses support 17 as support.
During operation, water is entered in the centrifugal chamber 6 by water inlet pipe 1 side direction tangent line, at first do the eddy flow circular motion that quickens isolating cylinder 5 around eddy flow in the runner between eddy flow acceleration isolating cylinder 5 and centrifugal chamber 6, after entering centrifugal chamber 6 middle parts, current are done the plane rotational flow motion, and relying on centrifugal force that its eddy flow produces that the solid sand grains is got rid of internal face to centrifugal chamber 6, sand grains and compiles to sand storage chamber 11 along wall precipitation downwards gradually under action of gravity simultaneously.Because the section of sand storage chamber 11 is greater than centrifugal chamber 6, water velocity descends, and sand grains is influenced by revolving force to weaken, and gravitate strengthens, and the silt particle particle just falls within the sand storage chamber 11 down naturally.On the other hand, the water velocity in eddy flow center and the sand storage chamber 11 is lower, and pressure energy is higher, so the eddy flow center is the liter waterborne of cleaning, and enters outlet pipe 10 through the secondary filter of turbination screen cloth 7.In running, when the reading difference of manometer 2 and 16 reaches certain value, need the system halt operation, unscrew spinning roller 14 then, open gland 13, the silt sand in the sand storage chamber 11 to be cleared up, intact bonnet upper press cover 13 screws spinning roller 14, can continue operation.In addition, also can uninterruptedly arrange sand in the running, to prolong the sand removal cycle by uninterruptedly opening flushing valve 18.
