Description

A kind of high-performance glass Wire-wound filter core

Technical field

The utility model belongs in liquid filtering and separation technology field, and in particular to a kind of high-performance glass line is around filter Core, for the separation and collection of solid impurity in liquid material, can apply to the filtering of nuclear power primary Ioops water.

Background technology

Filter core is the core filter element in core type filter, point for having single and multicore filter, and filtrate is by filter Bottom inlet tube is flowed into, flow direction outside filter core to filter core self-filtering, the line of the excessively required accuracy class of Liquid Penetrant The filtrate for meeting and requiring can be obtained around filter core.Wire-wound filter core belongs to in-depth filtration, and the impurity to be removed is blocked by granular size Cut in the whole filter area of Wire-wound filter core and filtering layer depth.Wire-wound filter core compares in application of aspects such as industry, national defence, scientific researches Extensively, its yarn application can be polypropylene, cotton, glass fibre, polyphenylene sulfide etc., but requirement of the nuclear industry to yarn compared with Height, it is general to use glass material, and the precipitation of silica is strictly controlled.The purpose of Loop Water Chemical Control is to reduce equipment Corrosion, reduces the radioactivity level outside reactor core, to control the reactivity of reactor core.

Utility model content

The purpose of this utility model is can be with achievable anti-cleaning again there is provided one kind in order to make up the deficiencies in the prior art It is raw, effectively extend the high-performance glass Wire-wound filter core of the service life of filter core.

In order to reach the purpose of this utility model, technical scheme is as follows：

A kind of high-performance glass Wire-wound filter core, it is characterised in that including fin, socket and inner frame, fin passes through epoxy Resin bonding one end of inner frame, socket by adhering with epoxy resin inner frame the other end；One is wound with inner frame Glass fiber yarn, the glass fibers are wound with the outside of strata ester length fibre spun-bonded non-woven fabrics, the fine spun-bonded non-woven fabrics of the polyester length It is 1~5 that dimension yarn crossovers, which are wound the rhombus quantity included on the filter layer with a plurality of diamond holes, a circumference, Along the length direction of filter core：Thread density on each rhombus diagonal is consistent.

Preferably, the side edge of upper end cover is provided with O-ring.

The utility model has the advantage that：

Realize and filter step by step, it is ensured that filtering accuracy, verified by experimental data, the traditional winding pattern of correspondence, this reality With the service life of Novel filter cartridge one times is added on the premise of filter efficiency is ensured.Heatproof is high, good corrosion resistance, can meet The requirement of nuclear industry level water filtration.

Structural representation when Fig. 2 winds for yarn in Fig. 1；

Fig. 3 is the schematic diagram of flower pattern on filter core.

Embodiment

The utility model is further described with reference to embodiment, but protection domain of the present utility model not only office It is limited to embodiment.

With reference to shown in Fig. 1-Fig. 2, a kind of high-performance glass Wire-wound filter core, including fin 2, socket 4 and inner frame 1, fin 2 By adhering with epoxy resin in one end of inner frame 1, socket 4 by adhering with epoxy resin in the other end of inner frame 1, asphalt mixtures modified by epoxy resin Fat glue chemical-resistance is excellent, meets the requirement of nuclear industry level water filtration.The end of socket 4 is provided with O-ring 5, and filter core uses O Type circle is sealed, good airproof performance, and installation and removal are convenient.The fine spun-bonded non-woven fabrics 6 of a strata ester length, glass are wound with inner frame 1 Fiber yarn is crisp, and easy fracture comes off, and first around the fine spun-bonded non-woven fabrics of last layer polyester length before interior skeleton coiling, this layer of non-woven fabrics exists Filter core flow is not influenceed while stopping fibre shedding.Glass fiber yarn is wound with the outside of the fine spun-bonded non-woven fabrics of the polyester length 3, filter layer of the glass fiber yarn cross winding formation with a plurality of diamond holes, the continuous cross winding of glass fiber yarn, Diamond hole has thousands of up to a hundred.The rhombus quantity included on one circumference is 1~5, flower pattern and weight determine filtering accuracy and Pollutant holding capability, flower pattern is that rhombus is more on the rhombus quantity included on a circumference, conventional Wire-wound filter core circumference, and precision is higher.Need What is explained is：Flower pattern (flower pattern is the rhombus quantity included on a circumference) on filter core, if the filter core of cylinder is splitted And deploy, form a rectangle, then i.e. the rhombus quantity flower pattern that rectangle width is included, as shown in figure 3, will After filter core expansion rectangularity, the rhombus on circumference is respectively 1,2 and 4 from left to right.Along the length direction of filter core： Thread density on each rhombus diagonal is consistent, such as at the position of A1, A2, A3 ... in Fig. 2.

Wound using the air-texturing glass fiber yarn for meeting nuclear industry level, glass fiber yarn also needs to pure through overheating Change ungrease treatment, glass heatproof is high, good corrosion resistance.

This filter core using unique line in mode, circumference rhombus quantity 1,2,3,4,5, correspondence filtering accuracy 0.5um, 1um, 5um, 10um, 25um, the different filtering accuracy of different flower pattern correspondences.From outside to inside (along filter on each rhombus diagonal Core length direction) thread density is consistent, but because filter core diameter from outside to inside diminishes, therefore thread density gradually increases from outside to inside Plus, tight structure, equivalent to precision from outside to inside from low to high, realizes and filters step by step, it is ensured that filtering in the outer pine of self-assembling formation Precision.Verified by experimental data, the traditional winding pattern of correspondence, this unique winding mode makes the service life of filter core exist Ensure to add one times on the premise of filter efficiency.

Finally it should be noted that：Above example only not limits the utility model and retouched to illustrate the utility model The technical scheme stated, therefore, although this specification the utility model is had been carried out with reference to each above-mentioned embodiment it is detailed Illustrate, still, it will be understood by those within the art that, still the utility model can be modified or equally replaced Change, and technical scheme that all do not depart from spirit and scope of the present utility model and its improvement, it all should cover new in this practicality In the right of type.
