Abstract

The utility model discloses a kind of support pad of miillpore filter, the upper mesh layer including mutually fitting closely and lower mesh layer, and cladding and upper mesh layer and the lower outer peripheral bound edge of mesh layer, and the mesh number of the upper mesh layer is greater than the mesh number of lower mesh layer；The upper mesh layer mesh number is in 80-150 mesh.The purpose of this utility model is to provide a kind of support pad of miillpore filter, to realize that batch in automation equipment negative-pressure adsorption, avoids miillpore filter deformation fracture.

Description

A kind of support pad of miillpore filter

Technical field

The utility model relates to one kind to be tested in the fields such as medicine, biology, environmentology using membrane separation technique, Detect the working surfaces of automation equipment, specially a kind of support pad of miillpore filter.

Background technique

Using miillpore filter make a collection of specimens in tangible substance and directly by filter membrane progress transparent processing set under microscope Carrying out observation is a novel morphologic detection technology, can be widely applied to the small tangible of medical test and other field Substance detection, but since miillpore filter softness and rapid wear lead to having one side to be limited to, the method used is substantially It is affixed directly to Double-layered cup bottom or is mechanically fixed by Double-layered cup, form filtration type miillpore filter cup.

Miillpore filter cup needs repeatedly to be dyed in the operation for automation equipment, and complete in a dyeing liquor Cheng Hou is generally taken away the dyeing liquor in miillpore filter cup by the negative suction system in automation equipment.

And in negative-pressure adsorption, due to the structural relation of the miillpore filter in miillpore filter bottom of a cup portion, with a thickness of generally 50 μ M or so, even more thin is 20 μm, and in negative-pressure adsorption, miillpore filter is easy to produce deformation, or even rupture.

Utility model content

The purpose of this utility model is in view of the above problems, a kind of support pad of miillpore filter is provided, to realize batch In automation equipment negative-pressure adsorption, miillpore filter deformation fracture is avoided.

In order to achieve the above object, the technical solution adopted in the utility model is: a kind of support pad of miillpore filter, including The upper mesh layer and lower mesh layer mutually fitted closely, and cladding and upper mesh layer and the lower outer peripheral bound edge of mesh layer, institute The mesh number for stating mesh layer is greater than the mesh number of lower mesh layer；The upper mesh layer mesh number is in 80-150 mesh.

Further, the mesh number of the lower mesh layer is 20-40 mesh.

Further, the upper mesh layer is steel wire, and thickness is in 0.1-0.2mm.

Further, lower mesh layer is formed using steel wire weaving, steel wire line footpath 0.5-0.8mm.

Further, the width of bound edge is in 1-4mm.

The utility model has the beneficial effects that realize that batch in automation equipment negative-pressure adsorption, avoids miillpore filter from becoming Shape rupture:

1, upper mesh layer and lower mesh layer combined support, and the mesh number of upper mesh layer is greater than the mesh number of lower mesh layer, online Aperture layer provides the permeability and dispersion stress of miillpore filter using the mesh layer of high mesh number, and suction function is avoided to fall into miillpore filter Enter into the mesh of lower mesh layer；And lower mesh avoids individually not enough collapsing using the support degree of upper mesh layer, makes Miillpore filter bottom is adsorbed out pocketed, and then influences detection.

2, lower mesh layer is formed using steel wire weaving, and steel wire line footpath 0.5-0.8mm provides good supportive, together When, make upper mesh layer and lower mesh layer have male and fomale(M&F) when contacting using steel wire weaving, the tension for avoiding liquid is blocked The mesh of the big upper mesh layer of mesh number.

3, the thickness of bound edge determines the size of miillpore filter contact surface, and the effect sealed when assembly.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

Fig. 2 is schematic cross-sectional view at A-A in Fig. 1.

Label character described in figure indicates are as follows: 81, upper mesh layer；82, lower mesh layer；83, bound edge.

Specific embodiment

In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model There is any restriction effect.

As shown in Figure 1, the specific structure of the utility model are as follows: a kind of support pad of miillpore filter, including it is mutually close The upper mesh layer 81 and lower mesh layer 82 of fitting, and cladding and upper mesh layer 81 and the outer peripheral bound edge 83 of lower mesh layer 82, The mesh number of the upper mesh layer 81 is greater than the mesh number of lower mesh layer 82；81 mesh number of upper mesh layer is in 80-150 mesh.

Preferably, the mesh number of the lower mesh layer 82 is 20-40 mesh, preferably 30 mesh.

Preferably, the upper mesh layer 81 is steel wire, and thickness is in 0.1-0.2mm, preferably 0.1mm.

Preferably, lower mesh layer 82 is formed using steel wire weaving, steel wire line footpath 0.5-0.8mm, preferably 0.6mm.

Preferably, the width of bound edge 83 is in 1-4mm, preferably 2mm.

In a certain embodiment, as shown in Fig. 2, bound edge 83 is circular ring shape, so that the rounded structure of integral platform.

In a certain embodiment, as shown in figure 3, bound edge 83 is regular quadrangle, so that integral platform is in regular quadrangle structure.

It should be noted that, in this document, the terms "include", "comprise" or its any other variant are intended to non-row His property includes, so that the process, method, article or equipment for including a series of elements not only includes those elements, and And further include other elements that are not explicitly listed, or further include for this process, method, article or equipment institute it is intrinsic Element.

Specific case used herein is expounded the principles of the present invention and embodiment, above example Illustrate the method and its core concept for being merely used to help understand the utility model.The above is only the preferred of the utility model Embodiment, it is noted that due to the finiteness of literal expression, and objectively there is unlimited specific structure, for this technology For the those of ordinary skill in field, without departing from the principle of this utility model, several improvement, retouching can also be made Or variation, above-mentioned technical characteristic can also be combined in the right way；These improve retouching, variation or combination, or not It is improved that the conception and technical scheme of utility model are directly applied into other occasions, it is regarded as the protection of the utility model Range.
