Description
Technical field
The invention belongs to sewage treatment field, in particular to a kind of canvas press cloth.
Background technique
Currently, well known filter press filter board generally lays discharge outlet in filter frame corner, in the middle part of filter plate or edge part is distributed
If permeable hole, discharge outlet is corresponded on filter cloth, the position of feed inlet corresponds to aperture, when filter cloth is covered on filter plate surface, on filter cloth
Aperture be overlapped with filter plate drainage hole and feed inlet, carry out filters pressing when, material is delivered in filtering chamber from feed inlet, solid formation
Matter is trapped between filter cloth, and filtrate reaches filter plate surface through filter cloth, and from the channel that the kick on filter plate surface is formed, flow direction is saturating
Water hole, then flow to discharge outlet through filter plate inner passage from permeable hole and discharge outward.
Filter cloth restricted lifetime will appear the position that filter plate permeable hole is corresponded on breakage, especially filter cloth after long-time service, by
In filter press charging, pressure-filtering process, material enters filtering chamber from feed inlet and is distributed to filter cloth surface, corresponding saturating on filter cloth
The position in water hole is since through the hole for after filter cloth being permeable hole, being different from other positions on filter plate has filter plate support, the stress
The presence of feature makes the oriented permeable hole position of the material in the region concentrate the trend squeezed, and filter cloth is compared with other portions in region
Position filter cloth stress is bigger, is easier to that fracture distress occurs.
Once breakage occurs in filter cloth, long breach is easily presented in damaged form, it will usually replacement filter cloth processing is carried out, even if not
The mode for more renewing filter cloth, breach being taken to repair, it is also desirable to by cleaning, drying, polishing, sticks and the processes such as mend or sew and mend, suppress,
It takes a long time, influences filter cloth use, and since breakage has existed, stress variation in damage zone will cause damaged development, thus right
Preventative reinforcement processing is carried out in filter cloth cracky region to be necessary.
Summary of the invention
The present invention overcomes the deficiencies of the prior art and provide a kind of novel filter press filter cloth, reinforces the strong of filter cloth damageable zone
The design of degree, to extend filter cloth bulk life time.
To achieve the above object, the technical solution adopted by the present invention is that: it includes filter cloth, and filter cloth is equipped with filter cloth pan feeding
Mouth, filter cloth drainage hole and permeable hole enhancement layer；When filter cloth is covered on filter plate, filter cloth feeding inlet is overlapped with filter plate feeding inlet, filter
Cloth drainage hole is overlapped with filter plate drainage hole, 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:
1, refer to that the region setting second layer filter cloth that filter plate permeable hole is corresponded on filter cloth, second layer filter cloth are and filter cloth phase
Same material or good water permeability and fragmentation parameters are close or more preferably filter cloth；
2, the braiding filter cloth for thickening or reinforcing in the region weaving of corresponding filter plate permeable hole；
3, it is corresponding to filter plate permeable hole and fine mesh support is set close to the filter cloth of one side region of filter plate；Support is gold
Belong to or the fine mesh support of other high-strength materials prevents or reduces the region under the premise of not influencing fluid flow rate
Filter cloth is squeezed to permeable hole.
The above permeable hole enhancement layer: being separate aperture for permeable hole on filter plate, permeable hole enhancement layer is circle, round
Diameter be 3-5 times of permeable hole aperture, be aperture in a row or in blocks for permeable hole on filter plate, permeable hole enhancement layer is corresponding
Permeable hole arranges situation in rectangle or other shapes, exceeds 1-3 pore size of permeable bore region.
It further include feeding inlet protective layer, the feeding inlet protective layer paints around filter cloth feeding inlet along filter cloth feeding inlet
The glue for playing invigoration effect of one week 1-5cm wide, the glue for playing invigoration effect is polyurethane glue.Filter cloth edge is equipped with edge bandage,
Filter cloth is strapped on filter plate by edge bandage.
The invention has the following advantages: the configuration of the present invention is simple, intensity are high, are hardly damaged, solves filters pressing machine filter
Cloth corresponds to the problem of permeable bore region cracky, extends filter cloth service life.It is suitble to industrialization promotion.
