Abstract
The utility model relates to a sealing structure of liquid filtering material. A soft sealing ring [4] is arranged along the four sides of the liquid filtering material between the base layer [2] forming the liquid filtering material and the filtering layer [1] or between the base layer [2] and the reinforced layer [3] of the sealing structure of liquid filtering material. The utility model can make the effective filtration area in use of the liquid filtering material and the ingress and egress holes [5] for materials included within the range of the sealing ring [4], and can ensure the filtering liquid material to be filtered can not leak in the filtering process due to pressurization under the double sealing insurance of the linear sealing and the surface sealing, therefore, the expected sealing purpose can be achieved.
Description
The utility model relates to a kind of filtering material of being made up of thin layer that is used for that fluid liquid filters, and relates more specifically to a kind of hermetically-sealed construction of liquid filtering material.
Liquid filtering material in the background technology is a flat state, as designed by the applicant and obtain the liquid filtering material of No. 93225887.5 Chinese patents, is a kind of plane liquid filtering material that is used for board and frame machine.It is by basic unit, the MULTILAYER COMPOSITE shape filtering material that filter course and enhancement Layer are formed, has the filtering accuracy height, acid and alkali-resistance, organic solvent-resistant, good chemical stability, though can be used for the filtration of high-precision liquid medium, but its plane structures shape its with sheet frame between to contact be face contact, no matter be foozle because of sheet frame, or the error of filtering material itself, or because it cooperates the cumulative errors that caused between the two, in use produce mutual blow-by state in a word unavoidably, when thereby filter liquide occurring and pressurizeing, the defective of seepage takes place in filter process.
The purpose of this utility model is to be to design a kind of structure that can guarantee to have between filtering material itself and the sheet frame firm sealing effectiveness, to guarantee combining closely between the two, prevents the phenomenon that the liquid material of required filtration leaks out from the gap.
The utility model is realized by following design: between the basic unit and filter course of described liquid filtering material, or between its basic unit and enhancement Layer, around the periphery in effective filtration area in the liquid filtering material and input and output material hole, with a kind of material of softness one circle is set and forms sealing ring.Described sealing ring is fixed when basic unit and filter course and the mutual heat seal formation of enhancement Layer liquid filtering material, and is shaped as ring, constitutes a part of new liquid filtering material.
Effect of the present utility model is tangible, when use has the liquid filtering material of hermetically-sealed construction described in the utility model, its with sheet frame between contact and not only have face contact, the more important thing is that having line between the sealing ring be made up of flexible material and sheet frame contacts, its line contact is extremely tight and firm when strengthening with pressure, sealing ring is all sealed effective filtration area in the liquid filtering material and input and output material hole again, liquid material to be filtered is in filter process under the double sealing state of linear sealing and face sealing, thereby realizes the desired effects that its sealing is not leaked fully.
Below in conjunction with accompanying drawing embodiment of the present utility model is described, thereby make CONSTRUCTED SPECIFICATION of the present utility model, characteristics, purpose and advantage clearer and more definite.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a structure section schematic diagram of the present utility model.
Among the figure: the 1-filter course 2-3-of basic unit enhancement Layer 4-sealing ring 5-input and output material hole.
The structure of the utility model embodiment now is described in conjunction with the accompanying drawings:
Shown in accompanying drawing 1,2, the hermetically-sealed construction of the described a kind of liquid filtering material of present embodiment, its for by comprise the basic unit 2 that the cotton fiber pulp constitutes and be divided into the filter course 1 of its both sides and liquid filtering material that enhancement Layer 3 is formed in, in its described basic unit 2 and filter course 1, or between basic unit 2 and enhancement Layer 3, be provided with the sealing ring 4 that a circle is made of the flexibility material along the surrounding of liquid filtering material.Described sealing ring 4 is with liquid filtering material effective filtration area and input and output material hole 5 in use, and all circle is listed in wherein.When using the utility model, liquid filtering material is at first contacted with the sheet frame phase line by sealing ring 4, and then soft sealing ring 4 is adjacent to tightly with sheet frame and forms a closed-loop when continuing to compress, and constitutes one deck sealing and ensures; Be close to sheet frame around the liquid filtering material simultaneously and formation face contact, constitute another sealing and ensure layer.And effective filtration area and input and output material hole 5 in the liquid filtering material of flowing through for material to be filtered all are enclosed in the category of sealing ring 4, and it can guarantee non-leakage under the two-layer guarantee of the face sealing of the linear sealing of sealing ring 4 and whole liquid filtering material.
In order to ensure the effect that contacts between sealing ring 4 and sheet frame, and for the purpose of the preparation of sealing ring 4 materials, the section of described sealing ring 4 is little circle for best.Circular sealing ring 4 help with sheet frame between line contact, it is better that it contacts effect, the flexibility of material is then guaranteed to contact between sealing ring 4 and sheet frame further, thereby helps realizing the sealing effectiveness of expecting.
