Abstract
A kind of hollow stainless steel welded filter of one side, supporting layer is fixed between stainless steel forming bottom plate and stainless steel cloth；The outward flange of stainless steel forming bottom plate and stainless steel cloth is welded and fixed；Support ring interval setting guiding gutter, between stainless steel forming bottom plate and stainless steel cloth, in the inner ring of supporting layer, the centre of stainless steel forming bottom plate, stainless steel cloth and support ring is provided with the fluid hole of insertion.It is an advantage of the invention that：Stainless steel forming bottom plate and stainless steel cloth outward flange integral solder, form single facer filter entirety, during back flush, edge firm welding, filter plate outer edge will not be torn, it is ensured that liquid quality after filter.Stainless steel cloth is difficult to be bonded impurity, is not easily blocked, and easily rinses.Upper pass surface stainless steel cloth space uniformity, stainless steel forming bottom plate ensure liquid do not leak, with above lead to, close below, the characteristics of intensity is high.
Description
Technical field
It is more particularly to a kind of to be applicable high viscosity, the filtering of high-temp liquid the invention belongs to a kind of liquid filtering element, and have
There is extremely strong pressure-resistant and anti-reflective rinse capability the hollow stainless steel welded filter of one side.
Background technology
Widely used stainless steel single facer filter plate is various in style currently on the market, and its structure is using outside stainless steel cloth
Edge covers means of press seals with stainless steel plate spot welding, sealing strip or lead welding is welded, and its shortcoming of the single facer filter plate of said structure is：
When filter needs back flush, due to edge weld strength or cover Compressive Strength not enough and make filter plate outer edge tear cause
Damage, it is impossible to filtered, liquid after filter quality problems is occurred, it is necessary to frequently be changed, cause a large amount of stainless steel materials
Waste.
Applicant applied for " hollow single-sided microporous filter plate for precoating diatomite ", application number on December 23rd, 2010：
201220676516.5, the filter uses polythene material one-shot forming for hollow form, is provided with up and down between two layers of filter
Support column, forms liquid collecting cavity between levels filter and support column, and levels filter is provided with micropore, upper level filter plate
Coat diatomite.The filter of this structure overcomes the problem of snapping of stainless steel filter plate, but by using for many years, exists following
Problem：1st, non-refractory, the filtering to high-temp liquid is not applied to；When the 2nd, backwashing, water is out of liquid collecting cavity to levels filter
Direction applies pressure, because its Material Strength is low, causes support column to be broken；3rd, the operation pressure between liquid collecting cavity and lower floor's filter
When power is too high, the easy compressive deformation of liquid collecting cavity causes liquid collecting cavity to block, and filter layer deformation, filter opening changes, and easily blocks；
4th, lower floor's filter plate relative aperture is smaller, rather than non-porous, during precoated diatomite varying aperture less, when shut down when, below diatom
Soil can come off, and the aperture of lower floor's filter plate changes in filtering, and filtering accuracy is unstable.
The content of the invention
It is to overcome above-mentioned defect there is provided a kind of hollow stainless steel welded filter of one side that the purpose of the present invention, which is, by
It is difficult to be bonded impurity in stainless steel cloth, is completed in filtered fluid particularly precoated diatomite layer filtering, be more easy to rinse, due to adopting
Complete welding technique is used, not by backwash intensity effect, is rinsed while being applicable gas and water mixing, its backwash rear filter plate restorability is
100%.
The purpose of the present invention is achieved through the following technical solutions：A kind of hollow stainless steel welded filter of one side, its
It is characterised by：It includes stainless steel forming bottom plate, stainless steel cloth, supporting layer and support ring；The stainless steel forming bottom plate is set
The lower floor in stainless steel cloth is put, supporting layer is fixed between stainless steel forming bottom plate and stainless steel cloth；Stainless steel forming bottom plate
It is welded and fixed with the outward flange of stainless steel cloth using addition stainless steel welding stick or from by the way of melting welding；Support ring is by upper and lower ring
Shape supporter is constituted, and the annulus interval setting guiding gutter between upper and lower annular support body, support ring is molded installed in stainless steel
Between base plate and stainless steel cloth, in the inner ring of supporting layer, fixed with supporting layer, stainless steel forming bottom plate, stainless steel wire
The centre of net and support ring is provided with the fluid hole of insertion.
The surface precoated diatomite layer of the stainless steel cloth.
The beneficial effects of the invention are as follows：
1st, stainless steel forming bottom plate and stainless steel cloth outward flange 0-40mm scopes are molten using addition stainless steel welding stick or certainly
Together, the single facer filter for forming a kind of circular, polygon and irregular shape is overall, works as filtering for the mode integral solder of weldering
When plate needs back flush, edge firm welding, filter plate outer edge will not be torn, and not result in damage, it is ensured that liquid after filter
Quality, without being changed.
2nd, the intensity of stainless steel forming bottom plate and stainless steel cloth is high, is not influenceed by back washing strength.
3rd, stainless steel cloth is difficult to be bonded impurity, is not easily blocked, and in filtered fluid, particularly precoated diatomite layer has been filtered
Cheng Hou, is more easy to rinse.
4th, upper pass surface is made by stainless steel cloth, space uniformity, under close for stainless steel plate make, it is ensured that liquid is not let out
Leakage, with leading to above, closing below, intensity is high.
5th, it is applicable gas and water mixing to rinse, its backwash rear filter plate restorability is 100%.
6th, the outward flange of stainless steel cloth and lower floor's stainless steel forming bottom plate, supporting layer and stainless steel forming bottom plate are firmly welded
Be connected together, be resistant to the forward and reverse pressure of high intensity and moment reverse impact, forming bottom plate, silk screen are indeformable, can Reusability,
Precoated diatomite layer is particularly suitable for use in use or high temperature, the filtering of high viscosity liquid.
