Bolt is a ducted body, and the top has through hole;
Also has the blocked ear that drops when preventing to filter the handle installation or removal on this filter handle top;
The water cap also has a positioning sleeve, and positioning sleeve is an opening annulus, and opening part is the staggered overlap joint of two parts up and down, at annulus one end the conical guiding conical surface, the expansion conical surface and gas booking groove is arranged, and on the external cylindrical surface of positioning sleeve locating shoulder is arranged.
This Long handed water cap of the present utility model can reduce the height of filter plant and improve the uniformity of air distribution and water distribution, and has replaced gas distribution, cloth jellyfish pipe, arm.
Describe the utility model with reference to the accompanying drawings in detail.
Fig. 1 is an assembling schematic diagram of the present utility model.
Fig. 2 is the cutaway view of filter.
Fig. 3 is the cutaway view of positioning sleeve.
Fig. 4 is the vertical view of positioning sleeve.
Fig. 5 is the cutaway view of filter handle.
Fig. 6 be along B among Fig. 5 to partial view.
Referring to Fig. 1-6, Long handed water cap of the present utility model is made up of bolt 1, filter 2, positioning sleeve 3, filter handle 4.
Filter handle 4 is a ducted body, on the bottom sidewall of filter handle 4, have an air water and regulate slotted hole 21, middle and upper part at the filter handle has a tapered pole 19, has air distribution hole 14 in the bottom of this tapered pole 19, has inlet opening 18 on the top of tapered pole 19, the top of filter handle 4 is the connecting portion that is connected with filter, this connecting portion constitutes by offering internal thread 15 on the top of filter handle 4, also have the blocked ear 16 that drops when preventing installation or removal on filter handle top, on filter, be provided with the water and air distributing hole 6 and the fibre bundle suppending hole 8 that are communicated with inlet opening 18.18 top is provided with spacing shoulder 17 in the inlet opening.
The top of filter 2 is one spherical, in the middle of the top of spherical crown is a cylinder spill platform with holes, the part that is connected with spherical crown is uncovered cylindrical shape, cylindrical inner at spherical crown, at the even a plurality of reference columns 5 that distribute of the lower end edge circumferencial direction of cylinder spill platform, match with spacing shoulder 17 in the lower end of this reference column 5.The nut part that has internal thread 15, one bolts 1 on the top of filter handle 4 with cylinder spill platform cooperates screw portion and the screw-internal thread fit of filtering handle.On filter 2, be provided with the water and air distributing hole 6 and the fibre bundle suppending hole 8 that are communicated with inlet opening 18.Fibre bundle passes wires such as hole 8 usefulness nylon ropes or non-metal rope 22 ties up on the filter.
Positioning sleeve 3 is opening annulus, and opening 12 places are the staggered overlap joint of two parts up and down.At annulus one end the conical guiding conical surface 10 is arranged, the expansion conical surface 9 and gas booking groove 14.On the external cylindrical surface of location body 11, locating shoulder 13 is arranged.The diameter of annulus can arbitrarily change.
During installation, with the conical surface of the conical surface of positioning sleeve 3 and filter handle 4 in the same way, be enclosed within the spacing shoulder 17 times of filter handle 4.Inject in the hole of porous plate filtering handle 4 and positioning sleeve 3 side along porous plate 23, the aperture of porous plate 23 is identical or bigger with the minimum external cylindrical surface external diameter of positioning sleeve 3.Because of the length of the blocked ear 16 of filter on the handle 4 greater than the aperture on the porous plate, can not drop so filter handle 4 and positioning sleeve 3 just are suspended on the porous plate.
After being connected on the filter 2 with rope sling, the reference column on the filter 25 towards porous plate, is set up filter 2 to fibre bundle, precession bolt 1, under the effect of screw thread axial force, the expansion conical surface 9 on the positioning sleeve 3 outwards expands under the effect of the tapered pole 19 on the filter handle 4.Because the external diameter of reference column 5 distribution circles is identical with the aperture on the porous plate, at this moment, the locating shoulder 13 of positioning sleeve 3 being crushed on the porous plate tightly, Long handed water cap just is fixed on the porous plate.Adopt the structure of positioning sleeve 3, the installation of water cap is just carried out on porous plate 23, needn't below orifice plate 23, stay the people to cooperate installation.
The course of work
During the filter plant operation, former water is discharged from through discharging device then through be pooled to the bottom of orifice plate behind the filtering layer by the aperture on the filter 26, inlet opening 18.
During the filter plant backwash, air and rinse water are sent in the space below the equipment porous plate simultaneously, and air has formed air cushion layer on the bottom of porous plate 23, the top of water under the restriction of the air distribution hole on the Long handed water cap 14.The height of air cushion layer is relevant with throughput.Throughput increases, and air cushion layer increases, otherwise reduces.
Rinse water is regulated slotted hole 21 from the hole and the air water of filter handle bottom, enters filter 2 through inlet opening 18, mixes with air enter filter 2 by air distribution hole 14 in, is assigned in the filtering layer by air distribution and water distribution hole 6 then.When air capacity too much made air cushion layer be increased to air water adjusting slotted hole 21, the top that air is regulated slotted hole 21 by air water entered Long handed water cap, and this moment, the height of air cushion layer stopped to increase.Like this, just played the effect of automatic adjusting air water mixed proportion.Also can reach the purpose of adjusting the air water mixed proportion by increasing or reduce the flow of air.The air water that enters Long handed water cap fully mixes in filter, evenly sends into filtering layer by air distribution and water distribution hole 6 again, makes filtrate reach sufficient cleaning.
Most preferred embodiment of the present utility model has more than been described, in design scope of the present utility model, can make multiple variation, as, without positioning sleeve 3, make the insertion below orifice plate 23 of filter handle 4, tapered pole 19 holes direct and on the orifice plate with the filter handle cooperate, and the filter handle is fixed on the orifice plate, but does not have blocked ear 16 on filter handle top.Bolt 1 also can be a solid.Can also the filter handle can directly be connected by modes such as screw thread or clampings with filter without bolt.Filter handle and filter can also be fastened together or be made of one, external screw thread is set, be connected and fixed with nut, or the hole on orifice plate is provided with internal thread, will filter handle and directly be fastened on the orifice plate at the orifice plate opposite side at filter handle end.Available plastics, fiberglass, stainless steels etc. such as filter, filter handle, bolt, positioning sleeve are nonmetal, metal or composite are made.This Long handed water cap is applicable to down to stream fabric filter (pond).Also be applicable to upward flow fabric filter (pond), this moment, long handle can shorten greatly.The scheme that the utility model provides also is applicable to sand filter (pond).
