CN2379192Y - High efficiency annular water tap's filter - Google Patents

Abstract

The utility model relates to a high-efficiency annular water cap. The utility model is used for discharging liquid and preventing exchanger from running off from a container or a filter pond which is used for filtering and adsorbing solid and liquid, and exchanging ions. The utility model is characterized in that the utility model is composed of a trapeziform cap head (1), a spherical gap (2), a threaded hollow stem (4) which is connected together with the cap head, a sealing gasket (5), two hexagon nuts (6) which are sheathed on the hollow stem, and a device which is used for fastening a plurality of serially stacked annular laminated sheets (7) on a perforated plate. The utility model has the advantages of high structural strength, large flow area and uniform gap size; the utility model can thoroughly discharge the liquid on the perforated plate. Meanwhile, the annular laminated sheets are connected with and fixed by each other by autologous arc-shaped projecting claws, and each annular laminated sheet is positioned accurately. In addition, the cross section of flow in the annular gap of the annular laminated sheets is in trapezium shape, which is similar to the most fashionable trapezium winding type stainless steel sieve tube at present, but the cost of the annular laminated sheets is only about 1/10 of the sieve tube. The utility model is an optimal substitute product for a water cap with a straight seam.

Description

Highly effective ring water cap

In industrial production and daily life, in order to obtain pure liquid, through means such as filtration commonly used, absorption, ion-exchanges liquid is handled, and use following material: inanimate matter natural siliceous sand (shape is random, granularity 0.5-1.2 millimeter), anthracite (granularity 0.8-1.8 millimeter), magnetic iron ore, walnut shell is fired (unsetting, 0.35～0.6 millimeter of granularity) activated carbon, bone carbon, wooden carbon, organic synthesis anion-cation exchange resin (1.2 millimeters of particle diameter φ 0.3～φ, the standard sphere) etc., above-mentioned substance general designation exchanger.In order to discharge liquid detention exchanger, use the water cap of multiple shape, as K type, mushroom-shaped, pagoda-shaped etc., be installed in container or the filter tank on the exchanger layer porous plate, general cap head contacts with exchanger, and liquid is discharged by hollow stem through cap head slit, and perhaps liquid enters from hollow stem, flow to the cap head and discharge (claiming backwash again), this is the basic function of water cap.Because container characteristics and liquid medium difference, the material of water cap has porcelain system, polyvinyl chloride, ABS engineering plastics, stainless steel etc., and shape has single head, double end, long and short hollow stem, and the slit value is determined with the exchanger particle diameter, particle is run off be principle.Four during the last ten years, makes water cap cap head slit almost all adopt vertical masonry joint (hollow stem axis relatively), also comprises the water cap of introducing in the overseas equipment, and this structure is generally used in power station, petrochemical industry, printing and dyeing, medical water treatment facilities, and its enforcement is as follows:

Fig. 1 (single head) Fig. 2 (double end) is existing water cap, material ABS, now with Fig. 1 its enforcement is described: the cap head is pagoda-shaped (1), two sections (can multistage) straight slot (2) are arranged on it, the cap head is bonded together with the hot pressing flange by base plate (3), be connected with worm-like hollow rod (4) on the base plate, sealing gasket (5), by two hex nuts (6), be anchored on the porous plate of equipment.

Through long-term result of implementation, prove cap head strength weak, when the exchanger layer resistance increases and tramples during installation, easily cause damages of breaking of cap head, or the slit is out of shape the leakage exchanger.Because base plate has certain thickness, cause on the porous plate fluid removal unclean, waste liquid retention effects equipment performance.More trouble is cap head slit after injection moulding is intact, on every vertical masonry joint all adhesion film, spend a large amount of manpowers and repair except that mucous membrane, guarantee the slit value.But still have the film that does not scrape off, and therefore reducing circulation area increases unnecessary resistance, and this is the greatest drawback of vertical masonry joint water cap.It is bonding not firm to occur indivedual cap heads and base plate in addition, and generation cap head in service comes off, and exchanger is run off, and not only suffers loss economically, even the major accident that causes the power station unit to be forced to stop transport.

The purpose of this utility model provides a kind of intensity height, has both guaranteed that the slit value was reliable, the annular water cap that has efficient performance again, and its enforcement is as follows:

Fig. 3 (single head) Fig. 4 (double end), materials A BS, by Fig. 3 its enforcement is described: ladder-shaped cap head (1), its underpart is annular (hollow stem axis relatively) slit (2), and worm-like hollow rod (4) links together sealing gasket (5) with ladder-shaped cap head, two hex nuts (6) on hollow stem, string is being folded the annular laminate patch (7) (when adorning last piece laminate patch turn-over use, make the slit on the porous plate face) of some quantity, be anchored on the equipment porous plate.

The utility model advantage is:

1. adopted annular laminate patch, stress surface is big, intensity is high, and any distortion does not take place.And laminate patch one side is the light face, and opposite side is that boss exceeds basal plane, so after the assembling of annulus, still evenly reliable.Also by laminate patch self circular arc projected claw, reach interconnect fixing, thereby make each sheet accurate positioning.This laminate patch is a utility model patent, its patent No. " ZL92206723.6 ".

2. according to the needs of circulation area, can increase and decrease annular laminate patch quantity.

3. it is big to exert oneself.Compare for 90 millimeters with pagoda shape vertical masonry joint water cap diameter phi with 70 millimeters of annular water cap diameter phi, under the identical situation of cap head height degree, and the slit area equates, so annular water cap efficient height.

4. the cap head keeps the slit on the porous plate face, so the liquid on the thorough emptying porous plate of energy does not stay waste liquid, has improved equipment performance.

5. can be by the particle diameter requirement of exchanger, hundred-percent arresting solid again not by solid particle obstruction, stuck, because of the slit is little interior big outside the trapezoid cross section, even clip in the slit, can wash out by backwash, recovers original circulation area.

6. guaranteeing that water cap slit has under enough circulation area conditions, also should possess the uniformity of collection (joining) water, so have equal discharge orifice on worm-like hollow rod, its total area ratio laminate patch circumferential weld gross area is little by 5%, has a mind to increase circulating resistance, reaches the liquid distributed uniform.

The utility model provides a kind of rational in infrastructure, the simple highly effective ring water of pattern cap to people, and annular laminate patch and nut all are to apply mechanically equipment to advance part in (row) water.Simultaneously should the annular lamination, similar in appearance to the trapezoidal stainless steel coiling screen casing of present fashion, and cost only is about 1/10th of a screen casing, is the optimal regeneration product of vertical masonry joint water cap.

Claims (2)

1. highly effective ring water cap is characterized in that: ladder-shaped cap head (1), and circular weld (2), worm-like hollow rod (4), sealing gasket (5) through two hex nuts (6), is being folded some annular laminate patches (7) to string, is anchored on the device of porous plate.

2. according to the device of claim 1, it is characterized in that the annulus that laminate patch is formed, lowest part leaves the gap on the porous plate being anchored on, can emptying liquid.
