Abstract
The invention relates to a method for manufacturing an activated carbon filter, which comprises the following steps of (1) preparing raw materials: putting powdered activated carbon and powdered activated zeolite into a raw material pool, putting an adhesive into the raw material pool, injecting water according to a weight ratio, putting synthetic fibers into the raw material pool, stirring, and wrapping two layers of non-woven fabrics on a porous plastic pipe; (2) adopting a suction forming method: the raw materials in the groove are gathered on the porous plastic pipe and finally fill the whole suction injector; (3) adopting an injection molding method: the feedstock will accumulate in the injection metal mold centered on the porous plastic tube and eventually fill the entire injection metal mold. The invention has the beneficial effects that: can effectively remove peculiar smell and free organic compounds in water, and can also remove trace heavy metals such as cadmium, lead, chromium and the like in liquid; no adsorption media such as active carbon and the like fall off, so that secondary pollution is effectively avoided; the removal rate of the cryptosporidium is high through the precise mesh ratio of the active carbon; the liquid flow rate increases and the resistance decreases.
Description
Technical field
The index that the present invention relates to carbon filter is improved and production technology; particularly relate to a kind of by active carbon, activated zeolite, adhesive, synthetic fibers, end cap, antiseep lining, the preparation method of what the raw materials such as catch net were made the possess active carbon filter of economic benefits and social benefits function.
Background technology
Traditional active carbon filter is a kind of filtration apparatus of tank body, its enclosure interior fills active carbon, be used for educt in filtered water, microorganism, part heavy metal ion, and effectively can reduce the colourity of water, its effect also mainly removes larger molecular organics, ferriferous oxide, chlorine residue.The absorption principle of active carbon is: the surface concentration forming a layer equilibration at its particle surface, then organic substance impurity absorption in activated carbon granule, uses the adsorption effect at initial stage very high; But the time one is long, and the adsorption capacity of active carbon can weaken to some extent, and adsorption effect also declines thereupon, if water quality is muddy in aquarium, Organic substance in water content is high, and active carbon will soon lose filtering function, so active carbon should regularly clean or replace.But the active carbon, the adhesive that directly adopt of such filter is extruded in the market; This series products only possesses the adsorption function of general active carbon, and fluid flow is little, can not Adsorption of Heavy Metals, such as lead, mercury, cadmium etc.Therefore, for above aspect, need reasonably to innovate prior art.
Summary of the invention
For above defect, the invention provides a kind of reasonable in design, can continuous seepage, the preparation method that effectively can remove some heavy metals, the active carbon filter of secondary pollution can be avoided, can be used for food and drink, the purification of chemical agent and filtration.
For achieving the above object, the present invention is by the following technical solutions:
A preparation method for active carbon filter, comprises the following steps:
(1) raw material is prepared: first, 100-325 object powdered activated carbon is dropped into feed reservoir, again powdered activated for 100-250 object zeolite is dropped into feed reservoir, appropriate adhesive is dropped into feed reservoir, be that 1: the 10 pair of feed reservoir injects water according to weight ratio, again synthetic fibers are dropped into feed reservoir, feed reservoir is stirred 20 minutes by automatic stirrer, two-layer nonwoven is wrapped on porous plastics pipe;
(2) the suction method of forming is adopted: pumped by the raw material of feed reservoir in raw material tank, porous plastics pipe is arranged on the central authorities of suction and injection device, opens suction and injection device, and the raw material in groove is gathered on porous plastics pipe and is also finally full of whole suction and injection device, again suction and injection device is backed off, obtain cylindrical filter;
(3) injection moulding is adopted: porous plastics pipe is arranged on the central authorities on injection of metallic mould, by raw material under the pressure of 0.4Mpa-1Mpa, slowly be injected in metal die, when maximum injection pressure reaches 1Mpa, keep injection pressure 2 seconds, raw material will be gathered in finally be full of whole injection of metallic mould in the porous plastics pipe injection of metallic mould that is axle center, finally, stop injection pressure, injection of metallic mould is backed off, obtains cylindrical filter.
When last phase tidying up is carried out to the filter adopting above step to obtain, columned filter is needed to place constant temperature oven, the high temperature evaporate to dryness of 110 DEG C-120 DEG C, then by non-woven wraps in cylindrical filter, sheath net is wrapped in and is surrounded by the cylindrical filter of non-woven fabrics; The two ends bonding plastic cement seal cover of described cylindrical filter, be enclosed within cylindrical filter by clear PE bag, and heating makes the thermal contraction of PE bag wrap column type filter.
The beneficial effect of the preparation method of active carbon filter of the present invention is:
(1) by high performance powdered activated carbon, the peculiar smell in water and free organic compound can effectively be removed;
(2) its active powder zeolite, can remove again the heavy metal of the trace in liquid, such as cadmium, lead, chromium etc.;
(3) adopt two-layer nonwoven to be wrapped on plastics multi-hope pipeline, absolutely not the adsorbing medium such as active carbon comes off, and effectively prevent secondary pollution;
(4) by the order number proportioning (thickness collocation) of accurate active carbon, can obtain the filtering accuracy of 0.5um, the clearance of Cryptosporidium reaches 99.98%;
(5) mixed structure of active carbon and synthetic fibers, makes flow rate of liquid increase, and resistance reduces.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the suction and injection device model schematic adopted of the preparation method of active carbon filter described in the embodiment of the present invention;
Fig. 2 is the injection of metallic mould schematic diagram that preparation method described in the embodiment of the present invention adopts.
Detailed description of the invention
As shown in Figure 1-2, the preparation method of filter described in the embodiment of the present invention, mainly comprises the following steps:
(1) raw material is prepared: first, 100-325 object powdered activated carbon is dropped into feed reservoir, again powdered activated for 100-250 object zeolite is dropped into feed reservoir, appropriate adhesive is dropped into feed reservoir, be that 1: the 10 pair of feed reservoir injects water according to weight ratio, again synthetic fibers (1.5d × 3mm and 2d × 2mm) are dropped into feed reservoir, feed reservoir is stirred 20 minutes by automatic stirrer, two-layer nonwoven is wrapped on porous plastics pipe;
(2) the suction method of forming is adopted: pumped by the raw material of feed reservoir in groove, porous plastics pipe is arranged on the central authorities of suction and injection device, after again suction and injection device being immersed groove, open suction and injection device, raw material in groove is gathered on porous plastics pipe and is also finally full of whole suction and injection device, again suction and injection device is backed off, obtain cylindrical filter;
