Description
Technical field
A kind of plate and frame filter press high rigidity filter cloth is the utility model is related to, belongs to industrial filter material technical field.
Background technology
The separation of solid and liquid of broad sense refers to the separation between solid phase and liquid phase in any system.Specifically, refer to production
In the liquid phase and solid phase of aqueous centre or final product separate, i.e., by solid particle and the work of liquid phase separation from suspension
Industry.Vacuum filter, pressure filtration and centrifugal filtration etc. can be divided into by realizing the equipment of separation of solid and liquid.Wherein, plate and frame filter press is
Sheet frame is extruded by hydraulic cylinder, the water in material is led to filter cloth discharge, reaches the purpose of dehydration, is widely used in chemical industry, pottery
The industries such as porcelain, oil, medicine, food, smelting, are also applied for industrial filter sewage disposal, and application field is extensive.
Filter cloth on plate and frame filter press is process by traditional textile technology and modern complex technique etc., is to determine
The key factor of solids in suspension particulate matter interception, it is the core component of solid-liquid separating equipment.Wherein, the woven filter of monofilament
Cloth is a kind of recent year filter medium newly developed, because silk fiber diameter is thin, fluid by when resistance it is small, run energy
Consume low.Filter cloth is handled by calendering etc. again after being made, and is not easily blocked, regenerability is good, and the rate of filtration is fast.In addition, its filter cake
Stripping performance is good, the excellent size stability of filter cloth.But monofilament filter cloth is straight-through pore structure, filtering accuracy is low, filter cloth surface
Monofilament wear no resistance.
It is a kind of filter material with bending channel aperture structure relatively with traditional woven filter cloth, needled punched nonwoven material
Material, can reach different filter effects by changing surface density.Non-woven material is because extensive with higher porosity
It is used as filtering material, filter medium efficiently can lead to filter cloth under low pressure, reduce energy consumption, improve efficiency.Therefore,
Needled punched nonwoven material is filtered for plate and frame liquid, is a kind of innovative product.But during plate frame filter work, its
The pressure applied to liquid is up to 5 tons, and this just proposes very high requirement to the mechanical property of filter cloth.And using Nomex as representative
Non-woven material, typically formed using chopped fiber by pinprick reinforcement, its mechanical property is poor, it is difficult to meet plate and frame pressure
The duty requirements of filter high-pressure filteration.The advantages of monofilament filter cloth and Nomex filter cloth, is combined, develops compound plate and frame filter press
With filter cloth, there is novelty.
It is non-to improve acupuncture further by the method for the second consolidations such as heat bonding on the basis of needled conventionally reinforcing
Its mechanical property of weaving material, it is proved to be a kind of feasible means.
Patent (application number CN201410528786.4) discloses a kind of non-woven two-layer compound suitable for paper diaper and led
Fluid layer and its production method, it is using ES, PP, viscose rayon as raw material, respectively by the ES fibers of PP, viscose rayon and different content
Net is uniformly mixed into, it is then that PP layers is compound by pre-needling with adhesive-layer, then two-layer compound water conservancy diversion is made by hot air technique
Layer, can effectively solve paper diaper product bleeds back problem.
Patent (application number CN201110314640.6) discloses a kind of nonwoven fiber sponge and preparation method thereof, with
ELK fibers and general purpose polyester fiber are mixed into raw material, carry out shredding first, and web is made in combing, and web is through laying net for shaping
Substrate is made in machine, and substrate is carried out into acupuncture processing with needing machine, and then base fabric is carried out with hot blast to be heated to polyester fibre surface
Fusing, then plated through hot pressing and surface, just it is fiber sponge body finished product after cooling and shaping.
Utility model content
Problem to be solved in the utility model is that existing sponge toughness, intensity and tensile property are poor, easily damaged or tear
Split.
In order to solve the above problems, the utility model provides a kind of plate and frame filter press high rigidity filter cloth, and its feature exists
In the filter cloth mixes acupuncture filter cloth for a kind of chopped fiber containing enhancing base fabric, and hot melting cohesion point, filter cloth are formed between chopped fiber
Extreme fiber partial melting.
Preferably, the filter cloth includes partial melting filter cloth surface layer compound successively, has the acupuncture of hot melting cohesion point
Short fiber layers, enhancing base fabric, the acupuncture short fiber layers with hot melting cohesion point, partial melting filter cloth surface layer.
Preferably, the surface density of the filter cloth is 350~600g/m2, thickness is 2.2~2.6mm, tensile strength 1500
~3500N.
Preferably, the enhancing base fabric is woven fabric, and the surface density of woven fabric is 50~150g/m2, it is through weft yarn fineness
1000~2000D, weft density ratio are 1: 1~1.5: 1.
Preferably, at least containing the low-melting fiber that a kind of fusing point is 90~140 DEG C in the chopped fiber.
Preferably, mass content of the low-melting fiber in chopped fiber is 15%~30%.
Enhancement layer base fabric in the utility model improves the intensity of Nomex, and hot blast, which is reinforced, to be made to form bonding between fiber
Point, further increase the strength and hardness of filter cloth；Surface calendering sizing makes filter cloth surface fiber partial melting, further improves
The hardness and surface flatness of filter cloth, hardness, wearability and the high filter cloth of filtering accuracy are obtained, filter cloth can be mitigated is using
During paste bag problem.
