Description
Technical field
The present invention relates to a kind of filter element and filter.
Background technology
The accurate filter of candle formula diatomaceous earth filter to be a kind of with diatomite be filter medium, also can use the mixture of perlite, active carbon or these powder as filter medium.As shown in Figure 1, filter is made up of two major parts: filter element 1(is referred to as filter element) and tank body 2, tank body 2 upper baffle installs diatomite filter element 1; After liquid to be filtered 37 enters tank body, under pressure through diatomite filter element, the suspension in liquid is tackled by the diatomite of porous, completes filtration, and the liquid 38 after filtration flows out above tank body 2.Existing filter element is formed primarily of support frame and filter cloth and fixing auxiliary, low cost of manufacture, disposal ability is large, for the light contaminant water filtration treatment such as swimming pool and water paradise, the support component gap of this kind of filter element is large, the filter mediums such as diatomite can not be carried, only be used to support its outer filter cloth, filter cloth plays the diatomaceous effect of carrying, this kind of filter element mainly adopts two kinds of structures, the first is the spring loaded support element that corrosion resistant metal (generally adopting stainless steel) is made, overcoat filter cloth, the filter element of this structure is spring structure in essence, longitudinally there is no supporting construction, natural torsion can be produced, because filter element is densely arranged at filtering tank, use in filtration in reality and can touch together below filter element, native effect is hung in impact.Meanwhile, during filtration, filter element can with current shifting in filtering tank, and the filter cloth being attached to its outside can be out of shape thereupon, and this will cause diatomite or particles of perlite through filter cloth, enters and pollutes the rear water of filter; Another major defect of this structure is because spring structure does not have longitudinal bracing, therefore minor diameter filter element (being generally less than 20mm) can only be made, relative to major diameter filter element, reach the filter element that identical filter area needs greater number, this adds increased manufacture and maintenance difficulty.The second filter element is plastic supporting structure overcoat filter cloth (as shown in Figure 2), its design feature is support section by a hollow VERTICAL TUBE, VERTICAL TUBE has multiple water inlet aperture, and outer surface cover is made up of support ring, with certain gap arrangement between each support ring.The maximum problem of existing plastic support elements is that support ring excesssive gap is large, all at more than 100mm, even reach 200mm, support closeness is inadequate, during work, filter cloth is subject to hydraulic pressure and can caves inward, when this just causes backwash, filter cloth is not easy de-soil, make filter cloth become triangle or polygon simultaneously, along with the prolongation of working time, the shape of filter cloth can be solidified, when filter cloth caves inward the triangle or polygon that are formed, two panels cloth can force together, the effective filtration area of filter cloth can reduce, filtering velocity is caused to rise, pressure reduction becomes large, filter cloth inwardly shrinks increasing, filtering traffic reduces, this just forms a kind of vicious circle, when limiting case, filter cloth surface sum filtering traffic can reduce 50%, filter cloth is shunk reach capacity, thus can filter cloth be drawn bad, diatomite can not adhere to, filter can not run well.Existing equipment operationally, for being very difficult for this to happen, in swimming pool environment for use, every three months needs to pull down filter element to half a year and cleans, for bus's flow water paradise, within 10 days sometimes, will block, cleaning brings heavy pressure to operation maintenance.Meanwhile, this cleaning can not ensure that filter cloth is indeformable, and the service life of filter cloth is often less than 2 years.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of filter medium easily comes off, long service life, filtering traffic are stable filter element and filter.
The present invention includes following technical scheme:
A kind of filter element, comprise the filter cloth for carrying filter medium and the elongated support member for supporting filter cloth, described support member inside is hollow structure; Described support member outside comprises at least 3 ribs extending longitudinally, and multiple and described rib extending longitudinally intersects vertically or the crossing support portion that tilts; Described at least 3 ribs extending longitudinally and multiple support portion form multiple intake chamber jointly; The spacing of adjacent two support portions is less than 20mm.
The spacing of adjacent two support portions is 4-10mm.
The external surface shape of support portion is circle, triangle or polygon.
The material of described support member is corrosion resistant metal material, is wound around and is welded on described rib extending longitudinally to form described support portion by wire.
The material of described support member is plastics, and described support member is formed by the mold pressing support unit assembled in series of multiple concentrically axis, and each mold pressing support unit comprises at least 3 ribs extending longitudinally, and the support portion intersected vertically with described longitudinal rib.
Described at least 3 ribs extending longitudinally equidistantly distribute.
A kind of filter, comprises above-mentioned filter element.
The filter medium of described filter is diatomite, perlite, active carbon or their mixture.
The present invention compared with prior art tool has the following advantages:
Filter element of the present invention comprises filter cloth and support member, described support member comprises cross-brace and longitudinal bracing, both actings in conjunction form intake chamber, thus filter cloth is no longer caved in, improve the service life of filter cloth and support member, filter medium easily comes off, and filter area and filtering traffic can not reduce, and overcomes the shortcoming of traditional candle filter filter element part.
