It is still too closely knit that yet above-mentioned existing filtering bodies 1 top layer filter material is selected for use, make water just and then to increase by the resistance of filtering bodies 1, relative hydraulic pressure also will and then increase, and bigger impurity also can be fast attached to filtering bodies 1 surface in the water, gradually the water yield that enable pass is crossed this filtering bodies 1 also can reduce, under state so, for forcing current to pass through filtering bodies 1, so hydraulic pressure all can rise higher and higher usually, and then constantly extruding is overlapping to force bigger impurity, to cause filtering bodies 1 to be scrapped at last, shorten the spendable time limit originally because of the too much impurity of outer fast deposition.In addition, the filter area of this kind filtering bodies is less, and the water yield of filtration is limited.

Summary of the invention

The purpose of this utility model just is to overcome the above-mentioned technical problem of existing in prior technology, and provide a kind of bigger filter area that both had, but disperse water flow path direction again, reduce resistance to water-flow, increase surface impurity capacity, a kind of purification of water quality that increases the service life porous type in-depth filtration body, the technical solution of the utility model is as follows: a kind of purification of water quality porous type in-depth filtration body, it has a filtering bodies, it is characterized in that: the current approaching face in filtering bodies offers several current introduction channels, these current introduction channels filter the internal layer direction extension that flows to by the outermost layer of filtering bodies to current, and offer the water conservancy diversion counterbore that becomes not penetrate whole filtering bodies, this water conservancy diversion counterbore is to be opened in filtering bodies with single density or by on the folded filtering bodies of forming of multilayer different density degree filter material.

Description of drawings

Fig. 1 is the section of structure of existing purification of water quality with filtering bodies.

Fig. 2 is the structural perspective of the utility model purification of water quality with filtering bodies.

Fig. 3 is the part section enlarged drawing after the expansion of filtering bodies shown in Figure 2.

Specific embodiment

Carry out the explanation of detail below in conjunction with 2 to 3 pairs of concrete structures of the present utility model of accompanying drawing:

A kind of purification of water quality porous type in-depth filtration body, it has a filtering bodies, it is characterized in that: the current approaching face in filtering bodies 2 offers several current introduction channels, these current introduction channels filter the internal layer direction extension that flows to by the outermost layer of filtering bodies to current, and offer the water conservancy diversion counterbore 21 that becomes not penetrate whole filtering bodies.Referring to Fig. 2 and shown in Figure 3.

This water conservancy diversion counterbore 21 is to be opened in filtering bodies 2 with single density or by on the folded filtering bodies of forming 2 of multilayer different density degree filter material.Referring to Fig. 2 and shown in Figure 3.

Be opened in water conservancy diversion counterbore 21 on the filtering bodies 2 and be separately independently or the reticulated cell structure that is communicated with each other each other.Referring to Fig. 2 and shown in Figure 3.

Be opened on the filtering bodies 2 water conservancy diversion counterbore 21 along filtering bodies 2 to offer the degree of depth be identical or the depth is different.Referring to Fig. 2 and shown in Figure 3.

Water conservancy diversion counterbore 21 is to offer along the approaching face ecto-entad extension of the current filtering direction of the filtering bodies 2 of hollow cylindrical or hollow, rectangular or hollow sphere.Referring to Fig. 2 and shown in Figure 3.

Water conservancy diversion counterbore 21 is that the current approaching face ecto-entad along the filtering bodies 2 of the different stacked formation of platy layer material of single density sheet filtering bodies 2 or multilayer density extends and offers.Referring to Fig. 2 and shown in Figure 3.

Water conservancy diversion counterbore 21 in the utility model is can be separately independent, as shown in Figure 2, also can offer to connect each other, its effect is identical, all is in order to increase water stream channel and filter area, and its perforate degree of depth can be by the water quality condition difference, water quality inferiority, the hole can be opened more shallow; Water quality is better, and the hole can be deeply, or is effective by the mutual configuration of the different layer materials of density.Such as, water quality is better, Kong Kaishen some, and the choosing by single density filtering material making filter body; As water quality inferiority, filter material that available multilayer is encrypted gradually constitutes, and the hole also can open more shallowly, more.

Below will be again 2 and 3 its work principle of filter and advantage be done further statement again in conjunction with the accompanying drawings:

As shown in the figure, this filtering bodies 2 is by the different filter material of multilayer density, and closely group is folded mutually constitutes, and offers some counterbores 21 downwards at its water purification approaching face.Under the different situation of the filter material density of each layer, usually can become closely knit gradually by top layer to the filter material density degree of deep layer, impurity bigger in the water will be blocked on the surface down, the impurity less as for other particles also can be stopped by each metafiltration material one by one, current pass through the internal layer of surface to filtering bodies 2 in advance and this counterbore 21 can make partly, less impurity is directly stopped by the deep layer filter material, and when current pass through counterbore 21, be not to fling the deep layer filter material yet, but can spread out from the inwall of counterbore 21, import passage and the drainage area of current when having increased it widely and purifying waste water, therefore, when purifying waste water, but the disperse water flow path direction, reduce resistance to water-flow, increase surface impurity capacity, prolong the service life of filtering bodies 2, quicken the effect of water purification, make that the water of last outflow filter body 2 is not have impurity.(this is above-mentioned to utilize the closely superimposed mutually and filtering bodies 2 that forms of multilayer filter material also can be replaced by the filter material of single density)

Design by numerous counterbores on the filter body, make water just and then to reduce by the resistance of filtering bodies 2, relative hydraulic pressure also can and then reduce, and bigger impurity also can be apace attached to filtering bodies 2 surfaces in the water, even if the opening of counterbore 21 is stopped up by bigger impurity, these current also can continue diffusion by other counterbore 21 and come, therefore, can can't therefore reduce by the water of filtering bodies 2, nor need make hydraulic pressure raise by filtering bodies 2 for forcing current, thereby increased the current area of its water purification approaching face, constantly extruding is not overlapping so just relatively be afraid of bigger impurity, has prolonged the service life of filtering bodies 2 indirectly.

Filtering bodies of the present utility model structure at filtering bodies itself and the set counterbore of water purification approaching face thereof, to be shaped as its necessary qualification, not decide by mould, constitutes the filtering bodies of the single or multi-ply construction of difference, and not limiting it here is any shape.

Above-mentioned structure design of the present utility model is different from the structure of existing filtering bodies, and is applicable in the various water purification occasions, creative and novelty, the pertinent regulations that meet utility application now propose utility application in accordance with the law, earnestly ask examination and patent power.
