Abstract

The utility model provides a resin filter system. The resin filter system comprises a filter drum and a plurality of filter elements fixed in the filter drum, a filter mesh of every filter element is a felt mesh formed by staggering and overlapping multiple layers of stainless steel meshes, and the filter drum is connected with a stress test device. The resin filter system has the advantages that the area of every filter element in the filter drum is many times larger than that of an ordinary tiled filter mesh, and the accuracy of the filter mesh can reach to 6 microns, so that most of mechanical impurities larger than 6 microns in the system can be removed, the filter effect is good, and mechanical performance and electrical performance of thin films can be improved; and the stress test device can be used for effective reminding of filter element replacement to prevent accidents in which production halts are necessary.

Description

A kind of resin filter system

Technical field

The utility model relates to the filter technical field, relates in particular to a kind of resin filter system.

Background technology

The manufacture craft flow process of Kapton is: resin is synthetic, hydrostomia, imines change into film, Kapton is for insulation industry and electron trade, require film surface that mechanical admixture can not be arranged, therefore need be before the hydrostomia film forming, resin is carried out multistage filtering, the mechanical admixture that contains in generation and the raw material in the production resin process is removed by filter completely, guarantee the pure of resin, thereby improve mechanical performance and the electrical property of Kapton.

In the prior art, the filter type that adopts is: make the plane or be trapped among on the drum post with stainless (steel) wire and make filter, the filter for molten filter area of said structure is little, again because screen pack is more coarse so filtering accuracy is low, weak effect, some more tiny impurity will drain in the system, and the degree of purity of resin is low, causes the electric property of film and mechanical performance low etc. bad.

The utility model content

At the problems referred to above, problem to be solved in the utility model provides the better resin filter system of a kind of filter effect.

The technical solution of the utility model is as follows:

A kind of resin filter system comprises the filter bucket and fixing a plurality of filter cores of crossing in it, and described each screen pack of crossing filter core is for by the staggered felt net that is formed by stacking of multilayer stainless (steel) wire.

Further, be connected with pressure test device on the described filter bucket, be used for measuring in real time the pressure that the filter bucket bears, when pressure reaches certain level, in time change the filter core of crossing that gets clogged.

Further, described each cross the number of plies of filter core stack stainless (steel) wire between 50 to 65.

Further, described each cross the height of filter core between 15 centimetres to 25 centimetres.

Further, fix four in the described filter bucket and cross filter core.

The beneficial effects of the utility model are: each filtration core area increases doubly a lot than the area of filter net of common tiling in the filter bucket, the screen pack precision can reach 6 microns, therefore all remove greater than 6 microns mechanical admixture is basic in the system, filter effect is fine, has improved mechanical performance and the electrical performance indexes of film; The effective prompting changing of pressure test device is crossed filter core, prevents the generation of the accident that must stop production.

The specific embodiment

Below in conjunction with accompanying drawing a kind of preferred specific embodiment of the present utility model is made brief description.

As shown in Figures 1 to 3:

A kind of resin filter system, comprise four mistake filter cores 2 that filter bucket 1 and Qi Nei are fixing, described each screen pack 4 of crossing filter core 2 is for by the staggered felt net that is formed by stacking of multilayer stainless (steel) wire, described each cross 60 layers of stainless (steel) wire of filter core 2 stacks, each height of crossing filter core 2 is 20 centimetres; Be connected with pressure test device 3 on the described filter bucket 1.

The resin of synthetic fluidised form flows into from the charging aperture of filter bucket 1, and under the effect of certain pressure, stream flows out through the discharging opening of filter core 2 backs from filter bucket 1, enters the hydrostomia film-forming process.In this process, because polyimide resin is the unusual liquid of thickness, viscosity is at 100000---200000Cp, therefore filtering needs very big pressure resin filter could be gone out, because it is continuous producing, through filtration for a long time, the impurity in the resin and the resin glue particle that is deposited in the system will be attached on the screen pack 4 of filter core 2, screen pack 4 is stopped up, and the pressure of system strengthens.Along with system pressure raises gradually, when being elevated to a certain degree, the sealing gasket of the end cap of filter bucket 1 will break or other problems occur, must stop production, so connect a pressure test device 3 on the filter bucket 1, when the pressure of the system of filtration reaches some values, the filter core 2 of crossing that blocks taken out, to shift to an earlier date ready another set of overanxious core 2 and pack in the filter bucket 1, in time change filter core 2 and avoided the problem that stops production.

More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
