Description

Liquid cleaning device

The present invention relates to a kind of device of decontaminating liquid, constitute by a container and the cup-shaped chimney filter that scavenging material is housed, this chimney filter sealably is inserted on the hole of container bottom, and have hole, cribriform liquid inlet at its axial end, have cribriform liquid exit hole (DE3409828A1) at its another axial end.

This device for example is used to purify the water of soaking beverage, especially tea in the family.But it also is applicable to other liquid basically.Following description relates to be as might use the water purification of representative.

Begin in the known devices of the DE3409828A1 that quotes of part at this specification sheets, the chimney filter that scavenging material is housed is inserted into the centre of container bottom, makes its end face on the height of container bottom, and stretches out from container.Water to be clean injects container.Ingate by chimney filter enters chimney filter then, and contacts with scavenging material in the chimney filter thus.For example adopt the granular ion exchange resin to purify.The water that flows through strainer tube should contact with scavenging material as far as possible enduringly.Flow out by chimney filter through the water that purifies then.Adopt this device can from water, eliminate impurity in the water that exists usually in Central Europe.

The objective of the invention is to, the device of mentioning in the above-mentioned part of this specification sheets is done further design, also can be effective when the impurity particle of water to be clean is big even make it, especially to germ, virus and bacterium etc.

Solution according to above-mentioned purpose of the present invention is as follows:

-on the top that is positioned at the use location, have in the chimney filter (3) of ingate and be equiped with the permeable masses that is adsorbed with sterilizing agent, and

-be positioned at the bottom, use location, be equiped with in the chimney filter by the particulate matter that is adsorbed with sterilizing agent, all liquid effusive by top and that contain sterilizing agent are forced to pass these particles along the path of leading to the chimney filter outlet opening.

The preferred iodine that adopts is as sterilizing agent.So below with iodine as might sterilizing agent example be described.

With this filtration unit water is carried out disinfection.In the chimney filter that water is purified, contained iodine carries out disinfection to all possible impurity in the water, and this especially also is applicable to germ, virus and bacterium or the like.Therefore this device is specially adapted to not meet at those sanitary conditions country's use of Central European standard.On chimney filter top, the closing the iodine amount and should remain on alap degree of commercial general ion exchange resin.But the iodine content of determining should make the iodine amount be enough to kill reliably described impurity.Consider also that in addition water should be enough to iodine is played one's part to the full in the length of the chimney filter top residence time.Iodine in the water will be adsorbed by the material in this section in the bottom of chimney filter.Therefore be through disinfectant by the effusive water of chimney filter, and especially aseptic.

In the dependent claims design of the present invention is explained.

In the accompanying drawings one embodiment of the present of invention are illustrated.

Fig. 1 is the configuration schematic diagram of apparatus of the present invention.

Fig. 2 is the enlarged view of this device.

The further enlarged view of Fig. 3,4 device details.

Fig. 1 illustrates a container 1, and this container is used to hold the water of receiving through purifying.Water is injected in thecontainer 2, this container is placed on the container 1 for this reason.Water is flowed out bychimney filter 3, and chimney filter is inserted on thecontainer 2, and the water through purifying flows in the container 1.In thechimney filter 3 scavenging material is housed.When container 1 and the corresponding size ofcontainer 2 employings,container 2 can partly insert in the container 1 at least.

Container 2 can adopt geometrical shape arbitrarily.It can be circular, oval-shaped or quadrate.Chimneyfilter 3 by its bottom from protruding.Container 2 has a hole on itsbottom 4,chimney filter 3 can be inserted on this hole, and plug-in mounting should make this hole closed hermetically.An annular sealing surface is shaped on the hole for this reason.Whenchimney filter 3 is equipped with a sealing duringtapered sleeve 5 being positioned at container bottom as shown in Figure 2, then can itself realize seal closures by chimney filter 3.Whenchimney filter 3 sizes hour, on the hole, can install sealing-ring.

Chimney filter 3 is cup-shaped.Be equipped with cribriporal on twoend face 6 and 7, one is prosopore, and another is a posticum, thereby can make the water that injectscontainer 2 along arrow P direction percolation strainer tube.Water through purifying is flowed out by the posticum of thechimney filter 3 that is positioned at the lower surface, use location.

The material that is adsorbed with iodine is equipped with on top inchimney filter 3 use locations, ion exchange resin for example, and the particle of absorption iodine is housed in the bottom of chimney filter.As shown in Figure 3, the material that is adsorbed with iodine is positioned atcenter pipe fitting 8, and this pipe fitting is preferably tubular, and axially parallel extends in chimney filter 3.Two axial ends ofpipe fitting 8 are equipped with screen part respectively.Be positioned at thescreen part 9 of pipe fitting 8 tops shown in Fig. 4.This screen part is again simultaneously the prosopore that water to be clean flows into chimney filter 3.Pipe fitting 8 by the alms bowl spare 10 of a bottom closure around, exactly, the wall of it and pipe fitting and bottom and lower screen cloth parts leave certain interval.Alms bowl spare 10 can be fixed on theupper cover plate 11 ofchimney filter 3, andscreen part 9 is located on this cover plate.But also can adopt other mode, it is arranged in the chimney filter 3.But under any circumstance, alms bowl spare 10 should leave with the wall ofchimney filter 3 and be disposed in thechimney filter 3, thereby at alms bowl spare 10 and 3 of chimney filters an annular intermediate cavity is arranged.Alms bowl spare 10 has ahole 12 of leading tochimney filter 3 at least on the wall of its upper end, use location.Comparatively suitable on alms bowl spare 10, be provided with two relative on diametric(al), or a plurality of on circumferential thehole 12 of mutual dislocation.Theparticle 13 of absorption iodine is positioned at the below of alms bowl spare 10.These particles preferably are full of the cross section ofchimney filter 3 bottoms.

The mode of operation of installing shown in Fig. 3 and Fig. 4 is as follows:

Water to be clean injectscontainer 2, passesscreen part 9 along the direction ofarrow 14 and enters in the pipe fitting 8.Water contacts with the ion exchange material that is adsorbed with iodine, and passes screen part in the lower end of pipe fitting 8 and leave pipe fitting 8.10 pairs of water of alms bowl spare are collected then.Water little by little is full of alms bowl spare, and the water level outside pipe fitting 8 raises as shown by arrows.Only when water level arrivedhole 12, water just left alms bowl spare 10.Adopt this mode, water can add iodine at preset time.The bacterium, virus and the germ that contain in most of water are killed at this moment.

Arrive 13 by the alms bowl spare 10 effusive water that are added with iodine on the path of leading tochimney filter 3 posticums, the iodine that contains in the water is adsorbed by particulate matter.The preferred implementation ofparticle 13 is activated carbon.Shown in the arrow among Fig. 3 15, the sterilized water that process purifies is flowed out by the posticum of chimney filter 3.Water arrives in the container 1.

In order for example to make in the material that is made of activated carbon, amount of iodine remains on lower degree, water should be contacted with activated carbon particle as far as possible for a long time, with absorption iodine.This point just can be realized in this way with the device of Fig. 3 and Fig. 4.But other scheme also is fine.For example substitute pipe fitting 8 employings the sleeve pipe that is adsorbed with the iodine material is housed, water maze formula ground percolation is crossed this sleeve pipe.Can save alms bowl spare 10 in the case.
