Description
Technical field
The invention belongs to sewage treatment area, more particularly to a kind of canvas press cloth.
Background technology
At present, known filter press filter board typically filter frame corner lay discharge outlet, in the middle part of filter plate or edge part distribution
If permeable hole, the position correspondence perforate of correspondence discharge outlet, charging aperture on filter cloth, when filter cloth is covered in filter plate surface, on filter cloth
Perforate overlap with filter plate osculum and charging aperture, when carrying out filter pressing, material is delivered in filtering chamber from charging aperture, solid formation
Matter is trapped between filter cloth, and filtrate reaches filter plate surface through filter cloth, and the passage flow direction formed from the kick on filter plate surface is saturating
Water hole, then flow to discharge outlet from permeable hole Jing filter plates inner passage and outwards discharge.
Filter cloth restricted lifetime, occurs breakage after life-time service, the position of filter plate permeable hole is especially corresponded on filter cloth, by
In pressure filter charging, pressure-filtering process, material is from charging aperture into filtering chamber and is distributed to filter cloth surface, and on filter cloth, correspondence is saturating
The position in water hole has filter plate to support due to through the hole for after filter cloth being permeable hole, being different from other positions on filter plate, the stress
The presence of feature causes the oriented permeable hole position of the material in the region to concentrate the trend of extruding, and in region, filter cloth is compared with other portions
Position filter cloth stress is bigger, is more easy to fracture distress.
Once breakage occurs in filter cloth, its damaged form is easily presented long breach, it will usually carry out changing filter cloth process, even if not
More renew filter cloth, take the mode that breach repairs, it is also desirable to by cleaning, drying, polishing, it is glutinous mend or sew and mend, suppress etc. operation,
It is time-consuming longer, affect filter cloth to use, and as breakage has been present, stress change in damage zone can cause damaged development, thus right
It is necessary for carry out preventative reinforcement processing in filter cloth cracky region.
The content of the invention
The present invention overcomes the deficiencies in the prior art, there is provided a kind of novel filter press filter cloth, strengthens the strong of filter cloth damageable zone
The design of degree, so as to extend filter cloth bulk life time.
For achieving the above object, the technical solution used in the present invention is：Which includes filter cloth, and filter cloth is provided with filter cloth pan feeding
Mouth, filter cloth osculum and permeable hole enhancement layer；When filter cloth is covered on filter plate, filter cloth feeding mouth is overlapped with filter plate feeding mouth, filter
Cloth osculum is overlapped with filter plate osculum, and the permeable hole enhancement layer of filter cloth covers the permeable hole on filter plate comprehensively；It is saturating on filter cloth
Water hole enhancement layer overlay area is beyond 1-5 pore size of permeable hole on corresponding filter plate.
Permeable hole enhancement layer can be following methods：
1st, refer to that the region of the correspondence filter plate permeable hole on filter cloth arranges second layer filter cloth, second layer filter cloth is and filter cloth phase
Same material or good water permeability and fragmentation parameters are close or more preferably filter cloth；
2nd, the braiding filter cloth for thickening or strengthening in the region weaving of correspondence filter plate permeable hole；
3rd, correspondence filter plate permeable hole and press close to one side region of filter plate filter cloth arrange fine mesh support；Support is gold
The fine mesh support of category or other high-strength materials, on the premise of rate of flow of fluid is not affected, prevents or reduces the region
Filter cloth is extruded to permeable hole.
Above permeable hole enhancement layer：For on filter plate, permeable hole is separate aperture, permeable hole enhancement layer is circle, circular
Diameter be 3-5 times of permeable hole aperture, on filter plate, permeable hole is perforate in a row or in blocks, permeable hole enhancement layer correspondence
Situation is rectangular or other shapes for permeable hole arrangement, beyond 1-3 pore size of permeable bore region.
Also include feeding mouth protective layer, the feeding mouth protective layer is painted along filter cloth feeding mouth around filter cloth feeding mouth
The one week 1-5cm wide glue for playing invigoration effect, the glue for playing invigoration effect are polyurethane glue.Filter cloth edge is provided with edge bandage,
Filter cloth is strapped on filter plate by edge bandage.
The invention has the advantages that：Present configuration is simple, intensity is high, be hardly damaged, and solves filter pressing machine filter
The problem of the permeable bore region cracky of cloth correspondence, extends filter cloth service life.Suitable industrialization promotion.
