Description

A kind of sheet-type absorption filter element and its preparation facilities and method
Technical field
The present invention relates to civilian or commercial Application environmental purification field, especially a kind of sheet-type absorption filter element and its system Standby device and method.
Background technology
Existing one kind filter core includes the fixed active carbon particle air purifying filter core of grid and folder charcoal cloth, and active carbon particle is empty Gas purifying filter element, but without enough load charcoal amounts and adsorption capacity, causes the problem is that while the big flux of air is taken into account Make long-time service adsorption effect poor, short life.The problem of pressing from both sides charcoal cloth and former type, while also production technology and use environment The shortcomings that unclean health.
Separately have a kind of first Patent No. 201410028954.3, a kind of preparation method of entitled pressed active carbon and into Type activated carbon uses " wet moulding " method to prepare pressed active carbon, i.e., first obtain containing activated carbon, binding agent, water activity Charcoal disperses slurries, then is injected into corresponding mold by required shape, then to mold and its internal activated carbon filled point Scattered slurries are freeze-dried to obtain pressed active carbon, which is stacked by multiple shaped activated carbons.Although It can be prepared into according to mold shape variously-shaped, but its production technology is complex, and adsorption capacity is not significantly improved.
Invention content
In view of the problems of the existing technology the present invention, provides a kind of sheet-type absorption filter element and its preparation facilities and side Method, having molding absorption filter element, load quantity of sorbent is big, and adsorption capacity is big, and mechanical strength is good, long lifespan, and production technology is efficient Continuously.
The technical solution adopted by the present invention is:A kind of sheet-type absorption filter element, it is characterised in that by adsorbent and binding agent Heating is pressed into tablet after particle is uniformly mixed into mixture, and through-hole is uniformly opened up on the tablet.It punches to improve fluid By flow, size, density and the distribution pattern in hole determine that this thin plate filter core can be adsorbed by a part of flow of fluid Agent particle size and its compacting compactness extent are also another factor determined through flow.Basic principle is that the size in hole is got over It is small more closeer better, to ensure the uniformity of absorption and adsorption efficiency.Whether the thickness of mixture determines final light sheet products Rigidity is flexible and pleated.
In general, light sheet products of the thickness less than about 2 millimeters can be come as producing paper as cloth with spool It stores and fixed.Thicker light sheet products can be cut into sizeable plank, be stored, and transport and sell, size The actual use demand in view of end user is needed with size.Flexible product can be used for various industry or civilian absorption field It closes, such as painting workshop, indoor wall finishing, roof of the vehicle interior trim, pet room, mask etc., to adsorb gas in enclosure space Harmful substance in body.Rigid filter core product can then be used in other occasions that filter core oneself is needed to have rigid structure, such as various Air purifying filter core etc..
A diameter of 0.1mm-5mm of the through-hole, more optimizedly 0.5mm-2mm.The pin hole in hole is got through by mechanical device needle Head or other manner are equably penetrated on thin plate filter core, size and density by target fluid flow and thin plate in itself Compactness extent is compacted to determine.
It is set off with cloth or paper bonding the top and bottom of the tablet.While permeability is ensured, enhance light sheet The globality of material and absorbent particles is prevented to be detached from.Various commodity molding cloth or non-woven fabrics on the market can be used as this mesh , the more optimizedly non-woven fabrics of high-melting-point high-permeability, such as polyester fiber non-woven fabric.Paper can be various with permeability Filter paper or forming paper.
The preparation method of the sheet-type absorption filter element of the present invention is as follows:By adsorbent, adhesive particle and other functionality Granular materials is uniformly mixed into evenly laid out after mixture, and then heat treatment melts binding agent, and then make absorbent particles It is set off, molding mixture is carried out uniform with cloth bonding by consistent mechanical molding bonded, and in the top and bottom of mixture Punching, then mixture is pressed into thin plate with holes.
Wherein radiant heat, conduction heat, advection heat or any combination thereof may be used in heating.Heating can be related to heat source, Including but not limited to heated fluid, steam, by hot inert gas, the secondary radiation of nano particle, baking oven, smelting furnace, flame, thermoelectricity Material, ultrasonic wave and similar heat source, or any combination thereof.The secondary radiation of nano particle can be by using electromagnetic radiation Nano particle is irradiated to realize, such as ultraviolet light, it is seen that light, infrared ray, microwave, radio wave and/or long radio wave.Especially That the secondary radiation heating (such as microwave) therein for having a penetration power more has superiority because it can realize from inside to outside plus Heat.Certainly more effectively mode of heating may be that traditional heating from outside to inside is combined with heating from inside to outside, realize To the rapid and uniform heating of mixture.
The present invention is prepared using preparation facilities described below, including conveyer belt, is set gradually on the conveyer belt The first non-woven fabrics roller bearing, feeder, material distributor, heater, the second non-woven fabrics roller bearing, cooler, punch and depress to Type device and cutter, absorbent particles and food-grade binding agent uniformly mix in feeder to be conveyed backward through conveyer belt, and first Non-woven fabrics roller bearing and the second non-woven fabrics roller bearing are arranged on the upper and lower part of the mixture of conveying, and heater is arranged on material distribution Between device device and the second non-woven fabrics roller bearing, the cooler is arranged between card punch and the second non-woven fabrics roller bearing.
Wherein the mode of screw feeding may be used in feeder, realizes uniform constant speed charging.
Punching and down-pressing forming device can realize punching and down-pressing forming simultaneously.This device can be by rolling with nail Roll shaft is punched or the tablet with nail is moved by position and punched, while can be compacted filter core, reaches required filter core Compactness extent.
The beneficial effects of the present invention are:
1. production technology high-efficiency and continuous, without using traditional moulds, heating cooling Quick uniform, production efficiency is high.
2. the molding absorption filter element of production has, load quantity of sorbent is big, and adsorption capacity is big, and mechanical strength is good, long lifespan.It is thin The design of plate in itself makes compacting compactness extent adjustable, and the design of pin hole more adapts to the demand of the filtering big flux of fluid.
The design of two layers of background layer and feeder (such as screw feeding) makes mixture particle not escape everywhere about 3., Make production and using all sanitation and hygiene.
