Abstract

The utility model relates to a split type liquid filter leaf. The utility model is characterized in that the utility model is formed by buckling two disk-shaped half leaves which have the same structure and are made of materials capable of filtering liquid. The utility model has the advantages that each half leaf can be formed independently in a tire mould to be sintered into a product because the utility model is formed by buckling two half leaves, and thus, the inner surface and the outer surface of the utility model can both keep smooth and have no stubble, and the utility model can prevent filtered liquid from being polluted by own fallen stubble in the filtering process; the utility model can be used again after use as long as the utility model is washed by clear water along an opposite direction.

Description

Split type liquid filtering sheet

The utility model relates to a kind of liquid filtering sheet, particularly split type liquid filtering sheet.

In industrial practice, people often need carry out filtration treatment to some liquid.Usually the liquid filtering machine that is adopted is by the body that inlet, liquid outlet are arranged, is contained in the axis in the body and several liquid filtering sheets of being made by filtering material of being socketed on the axis constitute, its operation principle is: pending liquid enters behind the filter along the axis axial flow, liquid will be subjected to each filter surface barrier in the flow process forward, liquid filters through the filter disc material and enters axis under differential pressure action, and what flowed out by the axis end port at last is filter liquide after handling.

Liquid filtering sheet of the prior art is as skeleton, be coated with one deck diatomite as the filtrate material at Skeleton Table face shield one filter layer of cloth, filter cloth outer surface by steel disc.The shortcoming of this filter is not ideal enough to the liquid filtering effect, particularly it is reused very inconvenient: could use again with overlapping after generally filter layer of cloth need being pulled down, washed later that loading onto lays equal stress on again and newly being coated with last layer diatomite.

The utility model purpose is: overcome the deficiency of prior art, the split type very easily liquid filtering sheet of cleaning that a kind of filter effect is better, repeated use is preceding is provided.

The utility model is achieved in that split type liquid filtering sheet, it is characterized in that: identical by two structures, form by fastening mutually plate-like half sheet that the material of liquid filtering is made.

On the such scheme basis, the utility model also can be realized like this: two plate-like half sheets fasten interface mutually and are provided with an elastic sealing gasket.Outward flange at plate-like half sheet of two fastenings is added with the rigidity snap ring.

The utility model advantage is:

1, owing to being fastened by two and half sheets, it forms, therefore each half sheet all can sinter goods in the tire die for molding separately, its inside and outside surface all can keep smooth, not have a hair slag like this, just can avoid its self hair slag in filter process to drop and has polluted liquid being filtered.

2,, before drop into reusing, only need to remove the foreign material that are detained in its filter opening, make it still to keep normal strainability along reverse (with respect to the flow direction under the last time user mode) flushing with clear water to it for the filter that was used.

Fig. 1,2 is the overall structure schematic diagram of split type liquid filtering sheet among the utility model embodiment.

Fig. 3,4 is half a sheet liquid filtering chip architecture schematic diagram among the utility model embodiment.

Fig. 5 is the utility model operation principle schematic diagram.

Below in conjunction with drawings and Examples the utility model is done further narration:

As Fig. 1, shown in 2, split type liquid filter disc is by last in this example, liquid filtering sheet (structure such as Fig. 3 of following two plate-likes, shown in 4, they all are to form with filtering material sintering such as ultra-high molecular weight polyethylene or polytetrafluoroethylene (PTFE), but their surfaces all have the countless micropores of infiltrate liquid) mutually fasten and form, be provided with the seal gasket 2 of an elastic material at the fastening interface, to guarantee that two and half sheet filters fasten the seal of the hollow of formation mutually, steel snap ring 3 is in order to guarantee lumping together the fixture that constitutes a unitary fluid filter by two and half sheet filters.Hole 5 is filter and the axis holes that socket-connect, and interstitial hole 4 then is to drive on the sidewall in hole 5, and it makes the middle space of filter communicate with the axis inner chamber.

Fig. 5 has illustrated a liquid filter to load onto its operation principle behind the filter that the utility model provides: filter 6 levels are put, and inlet 7 is opened in the left side, and several filters 15 are socketed on the axis 10, place in the filter 6.Axis 10 left ends are hold-down nut 8 and pad 9, and right output port 13 leans out filter 6 as clean liquid liquid outlet, has the middle perforate 4 of some inlet openings 11, respectively corresponding each filter 15 on the axis 10.After liquid to be filtered is sent into filter from mouth 7, under differential pressure action, will flow from left to right, infiltrate wherein aerial from its surface when flowing to each filter 15, on this " infiltration " process nature is exactly the process that is filtered, and this strainability and effect thereof are determined by material self performance and the manufacturing process of making filter.The liquid that enters each filter hollow has been filtered clean liquid, and they import axis 13 respectively by hole 11, under differential pressure action, sends from mouth 13 at last.

Claims

1, split type liquid filtering sheet is characterized in that: identical by two structures, form by fastening mutually plate-like half sheet that the material of liquid filtering is made.

2, filter according to claim 1 is characterized in that: two plate-like half sheets fasten interface mutually and are provided with an elastic sealing gasket.

3, filter according to claim 1 and 2 is characterized in that: the outward flange at plate-like half sheet of two fastenings is added with the rigidity snap ring.
