Definitions
- the invention relates to a backwashable filter device for filtering a liquid, in particular in domestic water systems.
- the invention relates to a backwashable filter device comprising a main filter, which is flowed through by the liquid in a normal operation of the filter device and in a backwashing operation of the filter device.
- a filter device has a pre-filter, which is flowed through in the backwashing operation.
- the filter device comprises a movable means for generating a crossflow (crossflow means), which is arranged immediately before at least a part of the prefilter and / or the main filter for cleaning the same in normal operation and / or in the backflushing operation.
- the cross-flow means comprises drive elements, which can be acted upon by a flow of the liquid for driving the cross-flow means.
- Such a backwashable filter device is known in particular from the publication with the publication number DE 10 2005 004 552 A1.
- the main filter is flowed through from the outside to the inside and in the backwash operation from inside to outside during normal operation.
- the displaceable main filter is associated with a prefilter, which ensures the continuous filtration function during the backwashing.
- a means for blocking the prefilter from the inlet is arranged, which can be opened or moved for the purpose of backwashing. Then the liquid is passed from the outside to the inside via the prefilter.
- the liquid filtered by the prefilter is guided into the interior of the main filter.
- the liquid is then passed through the main filter to the outside.
- the cleaning can be enhanced by a spraying or spraying device (impeller), which can be rotatably mounted in the interior of the main filter.
- the filter means comprises one or more elements (guide elements) adapted and arranged to direct the flow of liquid in one direction onto the drive elements of the cross-flow means.
- a filter device may comprise a housing which encloses the main filter, the pre-filter and the cross-flow means.
- the filter device may have means for shutting off (blocking) means of the prefilter against a liquid flowing into the filter device during normal operation.
- the guide elements may be attached to a first of the shut-off or be integrally connected to the locking means. It is also possible that the guide elements are arranged on the inner wall of the housing. The guide elements are advantageously arranged in a space between the housing and the first shut-off or protrude into this space.
- the helices forming the channels and / or the guide elements may have an angular extent of 190 ° to 250 °, but preferably an angle of 210 ° to 270 °.
- the helix or the helix may have a pitch of 0 ° to 20 °. Ie. , the liquid flows out almost in a circular path out of the channel.
- the filter device preferably has two guide elements, which are arranged symmetrically to each other.
- the two guide elements then form two channels together with the first shut-off means and the housing.
- the pre-filter of a filter device according to the invention may be displaceable for the change from normal operation to the backwash operation.
- the first shut-off can be bell-shaped and the pre-filter can be inserted in normal operation in the first shut-off and pulled out in the backwash from the first shut-off.
- a space between the pre-filter and the housing, on the one hand, and a space between the main filter and the housing, on the other hand, can be separated from one another in the backwashing operation, preferably by a second shut-off means and a third shut-off means.
- An inlet of the filter device is advantageously connected directly in normal operation with the space between the housing and the main filter and the backwash directly to the space between the housing and the pre-filter.
- FIG. 1 shows a partial section through a filter device according to the invention in normal operation
- FIG. 2 shows a detail of FIG. 1 from the upper region of the filter device in section
- FIG. 5 is a partial section of the filter device according to FIGS. 1 to 4 in the backflushing operation
- Fig. 7 shows a detail of the filter device in the backwash according to FIG. 6 with further cut parts
- the filter device 1 according to the invention shown in Figures 1 to 8 has a valve 10 which can be connected via an inlet connection 1 1 and an outlet connection 13 with a feeding or continuing line.
- the inlet region 12 and the outlet region 14 of the fitting are separated from each other.
- a manometer for monitoring the outlet side pressure is connected to a measuring port 16 in the outlet area.
- a connection 17 is arranged for connection of a further pressure gauge or other measuring instrument for monitoring the inlet, which in the present case, however, is closed by a plug 140.
- the ring 1 1 1 of the bearing means 1 10 is connected to the housing 20 in the region of Ruth Whyauslasses 21.
- the filter insert is guided in the lower region of the housing 20 by a guide means 120, which has a ring 121 which cooperates with the outside of the filter element bottom 83 during normal operation of the filter device 1 in order to shut off the region of the backwash outlet 21 from the flow-through volume of the fitting 10
- a guide means 120 which has a ring 121 which cooperates with the outside of the filter element bottom 83 during normal operation of the filter device 1 in order to shut off the region of the backwash outlet 21 from the flow-through volume of the fitting 10
- wedge-shaped elements 122 pointing in the direction of the backwash outlet 21 are fastened.
- the wedge-shaped elements 122 are fixed at a uniform distance from each other on the inside of the ring and guide the filter cartridge 80 when it moves toward the Ruth Cyprusauslass 21 in the backwash operation.
- a second shut-off means 60 is fixedly connected to the filter cartridge.
- the second shut-off means 60 is formed by a cross-sectionally L-shaped ring which is arranged on the outside of the substantially hollow cylindrical filter insert 80.
- This second shut-off means interacts with the first shut-off means 50 during normal operation of the filter device 1 and prevents water from entering a space between the first shut-off means 50 and the pre-filter 81.
- the second shut-off means 60 cooperates with a third shut-off means 70, which is arranged annularly on the inside of the housing 20 is arranged.
- the cooperation of the second shut-off means and the third shut-off means 70 prevents a direct connection of the space between the housing 20 and the pre-filter 81 on the one hand and the space between the housing 20 and the main filter 82 on the other hand.
- a liquid which is inside the prefilter 81, may enter the channels through the prefilter 81.
- the liquid is then passed through the channel through the ring 103 and the bores in the collar 61 so that the liquid can pass through the second shut-off means 60.
- a liquid flow from the outer space of the prefilter 81, through the prefilter 81 into the interior of the prefilter 81, from the interior of the prefilter 81 through the prefilter 81 into the channel of the crossflow means 100 is possible. From the channel, the liquid can then flow through the holes in the collar 62 of the second shut-off means in the space surrounding the main filter 82 and on to the backwash outlet 21.
- guide elements 51 are attached on the outside of the first shut-off 50 . These guide elements 51 are helically placed around the bell-shaped body of the first shut-off 50 and attached to this or preferably integrally formed therewith.
- the helix formed by the guide elements 51 tapers in the direction of flow.
- the liquid is impressed on the helical exit in a direction which is approximately perpendicular to the main flow direction of the flushing medium.
- the helical exit may have a residual tilt of about 5 ° to 20 °.
- the two guide elements are configured axially symmetrical to the central axis of the bell-shaped body of the first shut-off means 50.
- a liquid flowing into the intermediate space between the first shut-off element 50 and the housing 20 is accelerated both in a vector aimed at the turbine blades 101 and subjected to an internal twist.
- this vector causes a better flow of the turbine blades 101 of the crossflow means 100.
- a better transfer of force from the inflowing liquid to the turbine blades 101 is achieved by the internal swirl of the liquid.
- a continuous drive of the cross-flow means 100 can be sufficiently secured in each operating state of the backwashing operation.
- an impeller 90 is rotatably mounted with spray nozzles 91, the function of which is already known from DE 2005 004 552 A1.
