Description
Technical field
The present invention relates to a kind of filter, more particularly, to a kind of for sewer, the cone helical filter of wash basin.
Background technology
The filter of the pond such as existing wash basin, kitchen basin sewer mouth is mostly tiny stainless steel cloth or opened
The current passed through are divided into one one by the stainless steel substrates of many circular holes, larger to the resistance of current, so as to cause lower water
Water velocity in pipeline is slower, it is impossible to takes away tiny dirt, easily it is deposited and attached on inner-walls of duct, so that
Cause the blocking of sewer pipe.
According to Ke Shi effects, the earth from the change of team drive the Northern Hemisphere move object or fluid along the direction of motion to right avertence,
The Southern Hemisphere is then to left avertence.So on the Northern Hemisphere, the water in pond can form right handed whirlpool when flowing downward,
The current of high speed can form siphonage in the S-shaped elbow by drainpipe, and the sewage in pipeline is excluded as early as possible, it is to avoid
Deposition of dirt forms blocking in pipeline.But existing netted or cellular filter hinders the rotation of current, also reduces
The speed of current, hinders siphonage, so as to cause the precipitation of dirt, exacerbates the blocking of pipeline.
The content of the invention
The invention provides a kind of filter for pond sewer mouths such as wash basin, kitchen basins, the filter
Cone helical structure is conducive to draining to pass through at a high speed, and draining further reduces downcomer in the spiral water flow of filter formation high speed
The blocking in road.
To achieve the above object, the present invention is using the metal strip thing coiling filter, and specific method is：
One kind cone helical filter, it is characterised in that：By metal strip thing, helically coiling is formed filter in the clockwise direction；Institute
Filter is stated including cylindrical shell and the Conical Shells With of cylindrical shell lower end is connected to, described cylindrical shell is along up time with metal strip thing
The retainer plate of pin direction some circles of the helically coiling in same level from outer ring to inner ring, Conical Shells With is set by retainer plate
Put in the tube chamber of sewer pipe, each layer metal strip thing of retainer plate is 0 in the pitch of vertical direction；
Described Conical Shells With with metal strip thing by wider one end apicad direction bore helically coiling in wide at the top and narrow at the bottom
Coniform circle body, the diameter of the wider one end of Conical Shells With is identical with the diameter of the minimum circle body of cylindrical shell, and Conical Shells With is wider
One end be connected with the minimum circle body of cylindrical shell, the Conical Shells With cone angle be 115 ~ 125 °；The metal strip of the filter
The gap for filtering debris is left between thing, it is downward that gap is set to continuous helical.
Further, leak circle is additionally provided between the cylindrical shell and Conical Shells With, the leak circle is existed with metal strip thing
Clockwise direction coiling curl cylindrical enclosure body, one end of leak circle is connected to the minimum circle body of cylindrical shell, other end connection
In the wider one end of Conical Shells With, the circle body diameter of the leak circle is identical with the diameter of the minimum circle body of cylindrical shell.
Further, the diameter of the maximum circle body of the retainer plate is more than or equal to sewer mouth internal diameter；Leak circle circle
Body diameter is less than the intraoral footpath of drain pipe.
Further, the leak circle is identical with Conical Shells With gap, and gap is 2 ~ 3.5mm.
Further, described metal strip thing is stainless steel band, or stainless steel wire.
Further, the stainless steel band of the filter and Conical Shells With bus are perpendicular, and turn on the outside of filter.
Further, the Conical Shells With cone angle is 120 °.
Further, the gap of the metal strip thing for constituting retainer plate is 0 ~ 3mm.
Further, the number of turns of the retainer plate is 2 ~ 3 circles.
The present invention turns to the helix shaped filter with certain taper using metal strip thing, can be drawn according to Ke Shi effects
The moving fluid for playing the earth Northern Hemisphere is deflected to the right, so as to produce clockwise rotation, the filter hand of spiral is up time
Pin, it is identical with the trend that Ke Shi effects cause water flow rotary, so as to accelerate the speed of the spiral water flow turned clockwise, make water
Siphonage is more readily formed by the S-shaped elbow of sewer pipe in stream, is easy to take away the dirt in pipeline, reduces the stifled of pipeline
Plug；Helical gap is left between the filter metal strip thing, is not only able to form spiral water flow, spiral metal band and pipeline
Wall is in certain angle, and bootable current rush at the inwall of pipeline with speed, form disorderly on inner-walls of duct at an angle
Stream, along with the effect of impulsive force, easily washes away the dirt that inner-walls of duct adheres to, it is to avoid dirt absorption subtracts on inner-walls of duct
Small tube diameter, reduces the blocking of pipeline；In the fabrication process, can as needed filtering objects size adjustment filter
Pitch between metal strip thing：Pitch is smaller, and the gap between metal strip thing is smaller, and the effect for filtering dirt is better,
But the flow velocity for the water for passing through filter can be smaller, when gap increases therewith between pitch increase, metal strip thing, pass through filter
The flow velocity of water can be bigger, but the effect of filtering dirt is deteriorated, and has larger dirt and causes blocking into sewer；Bore spiral
The gap of filter is adjusted by the taper of Conical Shells With drift angle, and taper is at 115 ~ 125 °, and cone helical filter is in identical height
Under, with suitable current gap, and will not caused by Conical Shells With taper is too small current impurity retention.
The present invention having the beneficial effect that compared with prior art：
1. the cone helical filter is the coiling of clock wise spirals direction, with reference to Ke Shi effects and continuous gap between screw, make to pass through
The current of this filter accelerate drainage speed quickly through filter and sewer pipe.
2. the continuous whirlpool for the current formation high speed for passing through the cone helical filter, is total to the S-shaped elbow of sewer pipe
Same-action formation siphonage, produces downward suction, the dirt in water is taken away, it is to avoid it is deposited in the duct.
, can will be attached 3. the spiral metal band for boring helical filter rushes at the inwall of pipeline to the inclination angle guiding current of duct wall
The rubbish in inner-walls of duct is washed away, it is to avoid the blocking of pipeline.
4. under conditions of height is certain, such as fixed sewer mouth of pipe depth, the cone helical filter can pass through circular cone
Shell drift angle taper adjusts the current gap of the filter, filter is coped with different filtering environment, meets a variety of filterings
Condition.
