Core of the present invention is to provide a kind of cylinder filter, carries out effective location in this device to flexible filter core.Another core of the present invention is to provide a kind of apparatus for treating sewage comprising above-mentioned cylinder filter.
Please refer to Fig. 1 to Fig. 3, Fig. 1 is the front view of cylinder filter specific embodiment provided by the present invention, Fig. 2 be in Fig. 1 A-A to sectional view, Fig. 3 is the water storage schematic diagram of cylinder filter provided by the present invention.
The cylinder filter that the present embodiment provides mainly comprises casing 3, cylinder filter core 4, guide wheel 1 and sealing gasket 2.
Casing 3 is the opening casing of a rectangle, one group of relative sidewall is called the first side wall and the second sidewall, be respectively used to the diverse location of stationary cylinder filter core 4, the first side wall of casing 3 is provided with a through hole, this through hole is connected with motor transmission shaft 5 by motor-driven bearing 11, motor transmission shaft 5, for stationary cylinder filter core 4 diametrically, more importantly transmits the rotary motion of motor.
Cylinder filter core 4 is the tubular structure parts of a metal framework, and surface is provided with filter screen 10, and filter screen 10 is generally stainless steel wire, copper wire or chemical fiber wire etc. and works out, and tensioning on framework, for the sewage in device is filtered.
Optionally, cylinder filter core 4 not necessarily metal material is likely PVC or other materials.
Cylinder filter core 4 is horizontally set in casing 3, and motor transmission shaft 5 to be fixedly connected in the end face of cylinder filter core 4 in the heart, and motor transmission shaft and cylinder filter core keep coaxial, and cylinder filter core 4 other end and the second sidewall are fitted.
Two guide wheels 1 are installed on the inwall of the second sidewall, and the axis of guide wheel 1 and the second sidewalls orthogonal, the periphery of two guide wheels 1 respectively with the upper left side of cylinder filter core 4 inner circle and upper right side tangent.Sealing gasket 2 is fixedly mounted on the inwall of the second sidewall, sealing gasket 2 is circular arc sealing gasket, the external arc of sealing gasket 2 and the inner circle of cylinder filter core 4 fit, and for by the downside of cylinder filter core 4 port and casing 3 inner sealing, sealing gasket 2 is symmetrical about the vertical perpendicular bisector of cylinder filter core 4 inner circle.
Optionally, sealing gasket 2 also can be other keepers.Use sealing gasket 2 to be in order on the basis of location cylinder filter core 4, the downside of cylinder filter core 4 and casing 3 inwall are sealed, allows former water be filtered by filter screen 10, flow out from the periphery of cylinder filter core 4, strengthen filter effect.
In the present embodiment, sealing gasket 2 is symmetrical about the vertical perpendicular bisector of cylinder filter core 4 inner circle, the arcuate midway point of sealing gasket 2 is the bottommost with cylinder filter core 4 inwall, the position of two guide wheels 1 should respectively at first quartile and second quadrant of cylinder filter core 4 end face, namely half side half side with the right side on a left side for cylinder filter core 4 end face upper semi-circle respectively, respectively cylinder filter core 4 is supported.The line of the arcuate midway point of sealing gasket 2 and two guide wheels 1 is connect acute triangle in cylinder filter core 4 port inner circle, these three keepers of sealing gasket 2, two guide wheels 1 and cylinder filter core 4 form at least three anchor points, 3 positions can determining a circle, and structurally, have two keepers to be formed cylinder filter core 4 to support, can ensure in support circumferentially and location, cylinder filter core 4 when rotated stressed comparatively even.
Optionally, the level height of two guide wheels 1 is identical, namely about the vertical diameter symmetry by the cylinder filter core 4 end face center of circle.The identical Impact direction full symmetric making two guide wheels 1 and cylinder filter core 4 of the horizontal level of two guide wheels 1, two guide wheels 1 stressed identical, the i.e. stressed symmetry of cylinder filter core 4 left and right sides and identical, can increase the balance of cylinder filter core 4, can extend the service life of guide wheel 1.
Optionally, on the basis that two guide wheels 1 are highly identical, the number of degrees of the circular arc between the contact point of cylinder filter core 4 and two guide wheels 1 are 100 degree to 130 degree, and the location of circle is just more accurate, stressed more balanced.
Optionally, because the downside of cylinder filter core 4 and casing 3 sidewall seal by one of the effect of sealing gasket 2 exactly, be not limited to above-mentioned situation in a sealing fashion, the lower port of cylinder filter core 4 can be carried out the method sealed by other, all should belong to the embodiment of the present embodiment.
Optionally, the arc angle of sealing gasket 2 is 100 degree to 230 degree.Cylinder is located by two guide wheels 1 and sealing gasket 2.Because cylinder filter core 4 need rotate, even if cylinder filter core 4 and tank wall are fitted, also certain gap can be had, and sealing gasket 2 not only can fill up this gap, prevent the former water of cylinder filter core 4 from flowing out from port, but also can cylinder be located, please refer to Fig. 3, Fig. 3 is the water storage schematic diagram of cylinder filter provided by the present invention, and sealing gasket 2 arc length directly determines cylinder moisture storage capacity, and sealing ring is compared guide wheel 1 and can be increased its moisture storage capacity.The moisture storage capacity computing formula of cylinder filter core 4 is
V＝[(L*R)/2-R
2*sin(θ/2)]*H
Wherein, V is the moisture storage capacity of cylinder filter core 4, and L is the arc length of sealing gasket 2, and R is the inner circle radius of cylinder filter core 4, and θ is the arc angle of sealing gasket 2, and H is the length of cylinder filter core 4.
From formula, when the inner circle radius of cylinder filter core 4 and length constant, the arc angle of sealing gasket 2 is larger, cylinder filter core 4 is better with the sealing of casing 3, corresponding moisture storage capacity is larger, and water is more filtered by filter cloth 10, can improve the efficiency of filtration.
Optionally, guide wheel 1 is bolted on the second sidewall, and other modes also can be adopted to fix.
Optionally, sealing gasket 2 is by pressing plate 6 and be bolted on the second sidewall, or is fixed on the second sidewall by sealing gasket 2 by glue bonding way.
Optionally, sealing gasket 2 is P type rubber gasket.The planar section of P type rubber gasket is fixed on wall box by pressing plate 6, and circle body part and cylinder filter core 4 inwall of P type rubber gasket are fitted.As the sealing medium of casing and cylinder filter core, effectively can avoid the spilling of former water, also can reduce the wearing and tearing between casing and cylinder filter core.
Optionally, above-mentioned guide wheel 1 and sealing gasket 2 all can replace the keeper of cylinder filter core 4 radial location with other.
Optionally, the water inlet 7 of casing 3 is arranged on the second sidewall, and is arranged in the port of cylinder filter core 4 correspondence, and delivery port 8 is arranged on the bottom of the first side wall.
The first side wall bottom of casing 3 is provided with the delivery port 8 of cylinder filter, and the second sidewall is provided with water inlet 7 and sewage draining exit 9, and water inlet 7 and sewage draining exit 9 are at the circumferential inner of cylinder filter core 4.For making former water enter cylinder filter core 4 from water inlet 7, and enter into casing 3 by the filtration of filter screen 10, then discharged by the delivery port 8 of casing 3.
The cylinder filter that the present embodiment provides, with three keepers that the line arranged on casing 3 inwall is inscribed in cylinder filter core 4, lay respectively at the upper left side of described cylinder filter core 4 inwall, upper right side and bottom, keeper is connect as in cylinder filter core 4 inwall circle, at least there are three anchor points between this keeper and inwall circle, two keepers being wherein positioned at upper semi-circle can also support cylinder filter core 4, by three anchor points cylinder filter core 4 positioned diametrically and support, thus the axiality of cylinder filter core 4 and motor transmission shaft 5 can be ensured, avoid the life-span affecting motor transmission shaft 5, improve the service life of device entirety.
