Description
The present invention relates to a kind of purifying waste water with the equipment of preparation tap water, this equipment comprises: one holds the filtration vessel of the tap water that is cleaned; One bottom filter core retainer, this bottom filter core retainer can be inserted in the filtration vessel and have the second doline neck and an intermediate cavity that is inserted with second filter core; The one top filter core retainer that cooperates with bottom filter core retainer, this top filter core retainer have first a doline neck that is used for first filter core; And one have water sending device water is delivered to the upper can of first filter core.
As everyone knows, the equipment that is similar to mentioned kind is used for removing the salt in the tap water in the family.Under the sort of situation, filtration vessel is a collection container, and it has a water outlet and leader as the water correction plant (BRITA-strainer) of well-known prior art.The structure of bottom filter core retainer that downside is combined with the second doline neck is the same with the BRITA structure of filter of prior art.But the top filter core retainer that has one first doline neck and be arranged on the collection container on the first doline neck so is placed on the upper limb, makes almost mutual superposition on same axis of two filter cores.A kind of like this equipment is used for purifying waste water, and what the water yield of purification approximately was decided to be a kettle or the best is double kettle amount.If wishing has a kind of equipment to be designed to purify a large amount of water, then the massiveness because it becomes so become inconvenient, in fact, may be operated this equipment by general ultimate consumer with regard to no longer including.Arrange because filter core is stack, the equipment of prior art has considerable height, and from the angle of reasonable use, this height can not unrestrictedly increase.
Many countries do not have enough tap water.On the other hand, well-known, for example have the scavenging agent of iodine resin by suitable scavenging agent, it is harmless that deleterious bacterium and virus can become.In addition, although pass through a strainer through the adequately disinfected water of chemical agent, this water still taste is not good enough, and this taste can further purify the back removal by for example filtering with gac or silver-plated gac.If want the equipment that desalts, so just to guaranteeing and to operate, will limit to purify required volume with two filter cores that are provided with continuously with the above-mentioned type.In other specific use, if use scavenging agent such as iodine resin, the container (filter core) that has described scavenging agent so must keep moist situation in the life cycle for a long time at one, and this equipment for prior art is impossible.
Therefore, an object of the present invention is the equipment design of prior art is become to be suitable for handling better a large amount of water in filtration vessel, for example 2 liters or 3 liters or more water, and the scavenging agent that preferably is provided at least one filter core keeps moist.
According to the present invention, in filtration vessel, when top filter core retainer and the upper can branch is arranged and in its lower section, when the mounting height of the second doline neck of bottom filter core retainer is higher than the mounting height of the first doline neck of top filter core retainer, just can realize purpose of the present invention.For making new treating plant also can be used for third world countries, outlying, isolated area and the place under this environment just in time, the present invention has a mind to abandon complicated technology, and replace the employing gravity principle, that is to say that the weight by water produces driven effect.Water is to dirty, and therefore, its layout has a corresponding structure.
In filtration vessel, the position of the second doline neck of bottom filter core retainer is than the height of the first doline neck of the top filter core retainer that is arranged on its next door.This provides the filter core that makes in the first doline neck to keep moist possibility.
The spaced apart particularly advantageous of upper can.In equipment of the present invention, the capacity of upper can be designed as 10 premium on currency, and it is used in the present invention.Because upper can is divided and to be arranged, just can be placed on it below the outlet at a water tap for example or water nozzle or spring or water source, filled with water, the other parts with treating plant of the present invention are assembled together then.Need supporting device be set to upper can, for example also be the upper flange of level, and it will be convenient to user's transportation by suitable stiffening device.This jar bottom is design like this, if a doline neck and this bottom are provided with all-in-one-piece, then it is easier to be more upright than this situation.Therefore, because the project organization that separates of the present invention, top filter core retainer can keep cooperating with filtration vessel, and upper can be taken off with dress water, and then loads onto again.As can be seen, even when handling a large amount of water for example 10 liters the time, treating plant of the present invention also has good operability.
On the one hand, if according to the present invention, the water sending device of upper can needs a delivery port with controllable shut-off valve.Because the may command shut-off valve, the user can accurately select the time of filtering beginning, and more particularly, when opening shut-off valve, the user makes does not have treated water to enter top filter core retainer by delivery port discharge downwards.On the other hand, the user can operate shut-off valve to close delivery port, then, when upper can still has portion water, in order for example to fill water, can take off upper can on the slave unit.Therefore, generally can further improve operation.
If delivery port is provided with a ring-shaped bearing piece that extends downwards, to close hermetically if upper can is annoying, this also is favourable to the present invention.Ring-shaped bearing piece is connected in its bottom at the downside of upper can, makes it become a kind of supporting leg and protects shut-off valve.For example, a valve lifter is arranged in the ring-shaped bearing piece movably, even also can not destroyed towards being placed down on the surface after upper can is taken off.If ring-shaped bearing piece is the form of a supporting leg, then also need to be provided with two supporting legs that separate, so that form the effect of a three-point support.
Ring-shaped bearing piece can be used for a more favourable function.It opens wide downwards, but it isolates the space around it to the periphery.Ring-shaped bearing piece is closed with the airtight feud of upper can then, plays the function of the additional stopping device of delivery port.More particularly, if the water of discharging by delivery port gathers the water surface and has arrived the lower rim of ring-shaped bearing piece or upwards risen and surpass the degree of described lower rim, then therefore the following outlet auto-closing of ring-shaped bearing piece, does not have treated water can not discharge the gastight jar again.Like this, ring-shaped bearing piece is closed for the bottom provides automatically, thus can the outflow filter container, and water just can not flow through with undesirable large vol, for example makes the filtration vessel overflow.Otherwise because the height of ring-shaped bearing piece, it may be influential to the water surface that just in time is suitable for helping treating plant work of the present invention.
In addition, replace the lower rim of ring-shaped bearing piece, can use a recess or a groove that is formed on the ring-shaped bearing piece wall.Then, because the water surface always rises,, thereby close ring-shaped bearing piece with respect to the outside until the highest part of recess.
In another favourable structure of the present invention, bottom under assembled condition and top filter core retainer are basically in the lateral profile of filtration vessel.Like that can design treating plant of the present invention quite compactly.Thus, the total height for the treatment of plant approximates at the filtration vessel of a side with in the summation of the height of the upper can of opposite side.
On the one hand, if according to the present invention, it is particularly advantageous that bottom filter core retainer has a cup-shaped intermediate cavity at the side of the second doline neck, the height of this cup-shaped intermediate cavity is less than the height of filtration vessel, but greater than the height of the second doline neck, its diameter can make it hold the first doline neck such as top filter core retainer.And the treating plant of existing technology has two filter cores, if owing to depend merely on gravity form through-flow, then these two filter cores arrangement that also will superpose, the present invention adopts different passages, more particularly, be because the second doline neck is arranged on the next door of intermediate cavity.Two filter cores all are arranged in the filtration vessel.Intermediate cavity is cup-shaped, and its bigger structure makes it can hold the first doline neck of top filter core retainer.With this method, first filter core just can be arranged on the next door of second filter core, and even on position on the low side a little, the result, after adorning water for the first time, in addition in the whole process of operation, intermediate cavity maintains water at equipment.The additional water of introducing intermediate cavity flows through the surface in the upper area on intermediate cavity usually.Even weir meter is facing the second doline neck a little toward having a down dip, still, as long as the intermediate cavity overflow, water always flows to the second doline neck.If a filter core is arranged in the intermediate cavity that water is arranged basically, so obviously, this filter core will keep good humidity.
Another advantage of this result of bottom filter core retainer is that feedwater provides a long path, because water is in order to reach filtration vessel, just must the shape sudden turn of events or baffling structure as passing by move.For example, water is downward through first filter core in the first doline neck at first carefully, and rise along it in the outside of the first doline neck in intermediate cavity, arrive the upper end of intermediate cavity up to water, water flows through overflow weir then, that is to say the surface of flowing through between the intermediate cavity of a side and the second doline neck that is connected, enter in second filter core that is arranged in the second doline neck, enter in the filtration vessel so that be downward through second filter core at opposite side.With this method, the scavenging agent in the filter core has the good opportunity that acts on water.
The present invention also needs, as long as in the first doline neck of top filter core retainer a through hole is set.The doline neck comprises it almost being columnar side surface in the BRITA of prior art strainer, and this cylindrical side surface slightly is shrunk to a gradually sharp structure downwards.Filter core is inserted in the top, and more particularly, it can only flow out filter core downwards with close the making from top next water with the gastight form of general liquid, flows out the bottom of doline neck again.Because the sidewall or the doline neck of doline neck itself have suitable height, just can determine or fixing water level that this water level guarantees that the scavenging agent in the filter core for example always keeps contacting to a certain degree with water, thereby makes scavenging agent keep humidity.With this method, can effectively avoid the decline of iodine resin effect.One exhaust-duct is linked to each other with through hole, and make it extend to the fringe region of filtration vessel.Can avoid reducing the length of the flowing-path from the through hole to the overflow like that.
In the present invention, also available upper end or loam cake are closed upper can, in the dress water hole of upper can a threaded cap are set.Upper end or loam cake need comprise an annular surface polygonal, oval or circular and that center on the dress water hole.Dress water hole itself is then removablely sealed with civilian dress water or the threaded cap that purifies by one.
If according to the present invention, also need to be provided with one have ring-shaped step or shoulder so that support the dress water hole of a prefilter or after-filter.Prefilter can be the silk screen of the plastic material system of for example a kind of coffee strainer or similar strainer form.Strainer also can comprise other material, and packing ring or the like can be arranged.The purpose that prefilter is set is to filter the suspended particle in the untreated water that flows to, dirty particle or similar particle.Though still enter upper can with this method bacterium and virus, dirty coarse particles has been filtered out by prefilter.
For making upper can satisfy the requirement of hermetically closing, threaded cap of the present invention preferably is connected with pressure plate rotationally, and the outward flange of pressure plate is because of the sealing pressurized on next door, dress water hole.For example, the width of the ring-shaped step on next door, dress water hole is put in addition such as an O shape circle space as sealing except that prefilter is installed.Then, when the upper end was closed, the outward flange of pressure plate at first leaned against on the O shape circle, and upward maintenance is motionless to be positioned at O shape circle, rotates threaded cap simultaneously, in its last rotation, O shape circle was applied enough pressure, made threaded cap be connected in the upper end airtightly.Because a radial outside flange, threaded cap is connected in the upper end of upper can airtightly, makes that upper can is by gastight closing after threaded cap is shut.
If first filter core that for example external diameter is littler than second filter core, length is shorter than second filter core is equipped with the scavenging agent of ion exchange resin (ion-exchanger resin), in this ion exchange resin, add iodine, it may have the intensive germicidal action, so, when water passes through first filter core, scavenging agent will produce the healthy decontamination effect improving of relation, because bacterium and virus have been killed, water has been sterilized to a certain extent.If second filter core is equipped with gac, may also be ion-exchange, the scavenging agent of silver-plated gac preferably, so just can remove the iodine taste, make the taste of tap water have tangible improvement in subordinate phase.
As an example, the human consumer who is considered is made of a family of four, and the human consumer of this composition needs for example 10 liters tap water every day.If supposing the through-flow time is the about 20-30 of 1 premium on currency minute, so, if according to the present invention, the filtration vessel perhaps volume of upper can needs 10 liters respectively.If evening, upper can was filled untreated water, open shut-off valve evening and begin to purify, so, just can obtain 10 liters purifying drinking water second day morning.
A kind of like this treating plant is sought after, and it can help many countries to solve health for want of and the problem of the tap water that causes.Open a water tap or water nozzle and just can from filtration vessel, flow out tap water easily.If setting the purge amount of a filter core is 3000 liters, so, before changing this filter core, a family of four that can be 10 liters of day consumption provides about 1 year tap water.

Shown in the figure is the water-purification plant of a preferred embodiment of the present invention, and this device is made of the order that the numbering of parts makes progress according to Fig. 2 following parts: a filtration vessel 1; One bottom filter core retainer 2, bottom filter core retainer 2 has the second doline neck 3 and intermediate cavity 5, and this second doline neck 3 is inserted with second filter core 4 separably; Top filter core retainer 6 on bottom filter core retainer 2, this top filter core retainer 6 have one first doline neck 7 and first filter core 8 that fits loosely in this first doline neck 7; Upper can 9 on top filter core retainer 6, this upper can 9 has the water sending device that is generally designated by numeral 10; And the prefilter on upper can 9 11, pressure plate 12, threaded cap 13 and plastic strip 14.
Bottom filter core retainer 2 fits loosely on the upper limb 17 of filtration vessel 1.Fig. 1 illustrates in a plurality of exhaust-ducts 18, this exhaust-duct of nationality, and the air on the water surface 19 in the filtration vessel 1 just can be overflowed up radially outwardly.
Can understand bottom filter core retainer 2 from the sectional view of Fig. 1 to 3 and the vertical view of Fig. 6.Be arranged in the plane 20 and this planar radially outside zone be a upright minor face edge 21, be used for centering to the top that fits loosely in the top filter core retainer 6 on the bottom filter core retainer 2.A depressed area 22 is arranged in last plane 20, and this depressed area 22 is essentially flechette-type in the vertical view of Fig. 6, and below had a macropore 24 and an aperture 25 by both ends wall 23 define.Be arranged on above the aperture among Fig. 6 and be used for supporting the installation leg that will be described below with following horizontal arc end part zone 26.Adjacent with macropore 24 and in its lower section be intermediate cavity 5.In an illustrated embodiment, the capacity of intermediate cavity 5 is about 1.4 liters, seal around it, and for being similar to the shape of cup.From surface 23 height H down of flechette-type depressed area 22 is 12cm, is 3cm to the low height h on last plane 20 up from surface 23.
What be arranged on 22 right sides, depressed area shown in Fig. 1,2 and 6 is aperture 25, this aperture 25 below adjacent with the second doline neck 3 that opens wide down.Second filter core 4 inserts in this aperture 25, as shown in Figure 1.The height H of the second doline neck 3
3Height H less than intermediate cavity 5.As can be seen from Figure 1, first filter core 8 is lower than second filter core 4 that is arranged in the second doline neck 3.
Top filter core retainer 6 can be embedded in the bottom filter core retainer 2, and Fig. 1 to 3 and 8 (supporting leg) illustrates the cross section of top filter core retainer 6, and Fig. 7 illustrates the vertical view of top filter core retainer 6.Top filter core retainer also by 27 at an edge that a wall 28 arranged round, this wall 28 with respect to the horizontal plane is at a slight tilt a little.The intermediate surface of top filter core retainer 6 has one for the stable elongate depressions 29 that is preferably formed as therein. Wall 28 and 29 tilts towards a water port 30, and this water port 30 is formed by a gradually sharp downwards frustum of a cone.The first doline neck 7 is connected the following gradually most advanced and sophisticated of water port, also can find out from Fig. 3.The first doline neck 7 also opens wide down, and is used for holding first filter core 8 shown in the insertion situation among Fig. 1.All watering slots 31 sizes that are provided with ring form of first filter core are identical, but they are with the diameter setting identical with second filter core 4.Yet, the ring of watering slot 31 be arranged on bottom filter core retainer 2 wall 23 horizontal planes below.The diameter of first filter core, 8 main bodys that contains scavenging agent is littler than the diameter of the first doline neck 7, so that around first filter core 8 annular space 32 is arranged.In the second doline neck 3, then do not have this space in the outside of second filter core 4.Because each filter core and especially first filter core 8 are to install like this, it is the upper end that airtight ground especially is clipped in the first doline neck 7 impenetrable liquid, when the horizontal plane in the first doline neck 7 33 rose, the pressure in the annular space 32 can increase to some extent.
Medium height position about the first doline neck 7, in the first doline neck 7 of some taper, a through hole 34 is set, air in the space on the water surface 33 rises outwardly by this through hole 34, enters the space on the water surface 35 in the bottom filter core retainer 2.Therefore, at work, the water surface 33 will rise to the height of about through hole 34, may also exceed a bit, but because the air pressure of the annular space 32 on the water surface increases, stop the water surface 32 further to rise.
Except shown in Fig. 1 and 2, a ring-shaped bearing piece 36 that also illustrates in Fig. 3 to 5 that ratio is amplified puts in the water port 30 of the frustoconical of top filter core retainer 6 from above.This ring-shaped bearing piece 36 is installed in the bottom 37 of upper can 9, and opens wide down with a disc format.The top of ring-shaped bearing piece 36 is sealed by bottom 37 except that delivery port 38.Ring-shaped bearing piece 36 is fixed a valve cone 40 around a valve lifter 39 at the top of valve lifter 39, and in the position of pointing out as Fig. 3 example, valve lifter 39 is closed delivery port 38.One spring 41 is biased to valve cone 40 position of closing.
Fig. 3 to 5 illustrates a driving stem or valve rod 42, and this valve rod 42 can rotate around a transverse axis 43, and in the mode of Fig. 3 and 4, valve rod 42 clockwise directions rotate can open valve 39-41 or delivery port 38.Valve rod 42 can be fixed on that position by drift stop 44.
The both sides radially relative of ring-shaped bearing piece 36 are provided with a rectangular tank 45,45 '.Be applicable to that at the groove shown in Fig. 4 right side 45 ' valve lifter 39 will be driven when the left-hand end of valve rod 42 is passed it towards the inside of ring-shaped bearing piece 36.
Right half part about first and the 4th quadrant place at top filter core retainer 6 shown in Figure 7 are storing apparatus or fabricated section 46, and Fig. 8 illustrates the section of storing apparatus 46.Supporting leg can put in storing apparatus 46.Described supporting leg is down stretched from the bottom 37 that separates the upper can 9 of a segment distance with ring-shaped bearing piece 36 in position.Allow upper can 9 to be placed on the plane surface at the ring-shaped bearing piece 36 of a side with at the supporting leg 47 of opposite side, with this method, its bottom 37 still is basic maintenance level.Give upper can 9 water fillings just easy like that.Fig. 3 and 4 also illustrates a opening 48 in upper can 9 bottoms 37, thereby allows the setting and the motion of driving stem or valve rod 42.
There is a flange 49 upper end of upper can 9, and this flange 49 is provided with on the horizontal plane and around jar and extends, and an annular upper end portion 50 is connected in flange 49 airtightly.In Figure 13, the sectional view of XIII-XIII intercepting along the line illustrates the outer peripheral shape in upper end.
There is a water injection hole 51 inboard of upper end 50, and it has a ring-shaped step or shoulder 52 so that prefilter 11 to be installed.Figure 11 illustrates the part sectioned view of the amplification of a ring-shaped step 52.Can see that adjacent with prefilter 11 is one can adorn the annular groove 53 of O shape circle in its outside.Radial outward also has a flange with internal thread 55 54 that protrudes upward.
As shown in Figure 1, after prefilter 11 inserts, pressure plate 12 is installed on the ring-shaped step 52 on every side of dress water hole 51, seals under the clamping pressure effect of the O shape circle in the opposing groove 53 of pressure plate 12 on come from.Figure 14 illustrates the vertical view of pressure plate 12, and there is axial joint 56 in the central authorities of pressure plate 12, because the instrument that comprises to relating to, joint 56 is preferably hollow.Threaded cap 13 is rotatably connected on the pressure plate 12 by joint 56.More particularly, joint 56 passes the hole 57 (Figure 15) of certain centrosome 58, and this body 58 that centers is parts of the threaded cap 13 shown in Figure 15 and 16.Leader's bar 59 extends laterally accross this threaded cap 13 to relative periphery edge at the top of threaded cap 13 from the one periphery edge, this handlebar stem 59 comprises the two parallel sidewalls that separate, after a plastic strip 14 was fixed by its hook 60 and 61, the top of handlebar stem 59 covered by this plastic strip 14.
It is to be noted that all ventages must be on the water surface 63.
As for use, to guarantee that at first valve rod or driving stem 42 are in the closed position.Open threaded cap 13 then and take off pressure plate 12, because the connection of joint 56 just can make threaded cap and pressure plate all can take off with a kind of motion.With a container or by water source pack into for upper can 9 water that needs purify, the incomplete clean tap water of for example packing into.Big dirty particle and suspended particle are stayed in the prefilter 11.Upper can 9 can only be adorned for example 3 premium on currency of part, also can fill entirely, can reach 10 premium on currency according to its capacity.
After this, threaded cap 13 is installed and is also passed through screw thread and gastight closing.The state that has occurred upper can 9 about threaded cap 13 shown in Figure 1 subsequently with upper end 50 and hermetically closing.
Then, move down valve rod 42, valve 39-41 enters position shown in Figure 4, and water port 38 is opened.Current advance the water port 30 of top filter core retainer 6 now, and flow through watering slot 31, and this watering slot 31 is arranged in first filter core 8 with annular and is arranged on its top.Water flows through first filter core 8, this first filter core 8 contain down straight-through its such as iodine resin, water flows out from the bottom of the first doline neck 7 again.Before using for the first time, filter core preferably immersed in the water about 10 minutes.Water flows downstream into the intermediate cavity 5 of bottom filter core retainer 2, and concentrates at there.When water further flow to intermediate cavity 5, the liquid level 35 in the intermediate cavity 5 slowly rose.Owing in the first doline neck 7 cross through hole 34 is arranged, the water surface can rise to the height in hole 34 in the first doline neck 7.Because the liquid level in the outside can upwards rise to the height above hole 34, the water in the intermediate cavity 5 can be installed into the height of the water surface for example shown in Figure 135.Then, the right side of water by wall 23 flow graphs 1, and flow to another hole and enter second filter core 4 that contains such as gac.Flow through after the filter core 4, the water that the sense of taste has purified splashes into filter container 1 and assembles and forms the water surface 19.The water surface 19 can rise to the upper limb of the groove 45 in the ring-shaped bearing piece 36, and air is overflowed by described venting port 18 outwardly at the top.
It is to be noted that owing to intermediate cavity 5 always is being equipped with under the situation of water, thereby first filter core 8 always contacts with liquid by through hole 34.If the water surface in the filtration vessel 1 19 falls, intermediate cavity 5 also maintains water.No matter the degree of filtration vessel 1 dress water how, upper can 9 can repeat to adorn water again.Obviously, close water port 38 with blocking-up water, adorn water again with them equally with valve 39 and 40.But, close and reopen after the valve 39,40,41, as long as groove 45 is not sealed by the water surface 63 in the delivery port 30 of top filter core retainer 6, water just can down flow out upper can 9.More particularly, when the water surface 63 arrived the upper limb of the groove 45 in the ring-shaped bearing piece 36, then this groove 45 was closed, and air can not flow through with compensation water and flow out upper can 9, so water just stops to flow out from upper can.
