Description
Technical field
The present invention relates to the molten medicine device of a kind of polyacrylamide, can solve " flake " problem that polyacrylamide occurs due to conglomeration in being dissolved in the process of water.
Background technology
Polyacrylamide (cpolyacrylamids) is called for short PAM, is the water-soluble linear high molecular polymer being formed through free radical polymerization by acrylamide (AM) monomer, is insoluble to most of organic solvents.Polyacrylamide is white powder or fine granularity thing, and density is 1.32g/cm3 (23 degree), and vitrification point is 188 degree, and softening temperature is bordering on 210 degree.
Polyacrylamide has good flocculability, can reduce the frictional resistance between liquid, can be used as the drag reducer of effective flocculant, thickener, paper strengthening agent and liquid etc., be widely used in the industrial departments such as water treatment, papermaking, oil, coal, mining and metallurgy, geology, light textile, building.
PAM is widely used as presence agent, filter aid, all spends agent etc. in field of papermaking.Its effect is the quality that can improve paper, improves de-watering of slurries performance, improves the retention of fiber fines and filler, reduces raw-material consumption and to the pollution of environment etc.The effect that PAM is used in papermaking depends on the activity of its mean molecule quantity, ionic nature, ionic strength and other copolymer.Nonionic PAM is mainly used in improving the filter of paper pulp, increases dry paper intensity, improves the retention of fiber and filler; Anionic copolymer is mainly as the wet reinforcing agent of doing of paper and presence agent; Cationic copolymer is mainly used in paper waste and processes and filtrating aid function, also has good effect in addition for the retention that improves filler.In addition, PAM is also applied to paper waste processing and fiber recovery.
It is standby that polyacrylamide generally all needed to be mixed with the dilute solution of 0.1 %～0.5% before using.Polyacrylamide fully dissolving just can be given full play to flocculation.
The dissolving method of existing polyacrylamide is generally that PAM is joined in the dissolving tank with mixing plant, and the mode stirring by limit edged makes PAM form colloidal liquid.In the water course of dissolution of polyacrylamide, often there will be bulk floc sedimentation and " flake " phenomenon, this " group " is difficult to dissolve, and can affect to a great extent the flocculating function of polyacrylamide, causes waste, also easily causes pipeline obstruction.In order to alleviate this phenomenon, extending mixing time is one of at present conventional mode.Although extend mixing time, can dissolve to a certain extent these established agglomerates, can destroy the long-chain of polyacrylamide simultaneously, occur molecular chain rupture, and lose the peculiar function of PAM.
Summary of the invention
In order to solve above-mentioned defect of the prior art, the invention provides a kind of molten medicine device that polyacrylamide is fully dissolved, can solve " flake " problem that polyacrylamide occurs due to conglomeration in being dissolved in the process of water.
In order to realize above-mentioned technical purpose, the present invention has adopted following technical scheme:
The molten medicine device of polyacrylamide, is characterized in that, described molten medicine device comprises: metering dry powder chemicals feeder, pre-wetted cylinder body, medicine dissolving device and with the storage bin of agitating device; Metering dry powder chemicals feeder is connected with water inlet pipe, is located at the top of pre-wetted cylinder body; Described medicine dissolving device is injector, is arranged on the connecting line between pre-wetted cylinder body and storage bin, and is connected with high-pressure hydraulic pump.
Wherein, metering dry powder chemicals feeder is for quantitative dosing; Pre-wetted cylinder body is for pre-wetted and preliminarily solubilised polyacrylamide dry powder; Medicine dissolving device enters pipeline for polyacrylamide after mixing water and pre-wetted and by mixed liquor injection; Storage polyacrylamide solution for storage bin.
Further, described pre-wetted cylinder body is provided with liquid level monitoring probe, can accurately control the amount of water in cylinder body.
Described medicine dissolving device has a press water import, a resin solution import and a mixture export; Press water import is connected with high-pressure hydraulic pump, and resin solution import is connected with pre-wetted cylinder body below pipeline, mixture export connecting conveying pipe road, and transfer pipeline is connected with storage bin.
Metering dry powder chemicals feeder, with self-measuring device, can quantitatively be added to pre-wetted cylinder body by polypropylene milling amine dry powder.Pre-wetted cylinder body is equipped with water in advance, for pre-wetted and preliminarily solubilised polyacrylamide dry powder, can adopt the materials such as plastics, enamel, aluminium or stainless steel.Medicine dissolving device is injector, and water under high pressure fully mixes therein with polyacrylamide after pre-wetted, and mixed liquor sprays via nozzle, from mixture export, enters in transfer pipeline out.The jet blower bore of medicine dissolving device is adjustable, can need to regulate according to difference, and in the present invention, jet blower bore is preferably 15.5-20.5mm, and storage bin is with stirring at low speed device, for further dissolving and storage polyacrylamide solution.
First Polyacrylamide Powder is quantitatively joined in the pre-wetted cylinder body of water by metering dry powder chemicals feeder, in pre-wetted cylinder body, tentatively dissolves, and then from resin solution import, enters into medicine dissolving device.Medicine dissolving device relies on water under high pressure, and the negative pressure that the high velocity stream forming through nozzle produces sucks pre-wetted polyacrylamide, mixes, and spray and enter pipeline from mixture export in hybrid chamber.Bulk floc sedimentation and " flake ", through mixing and the jet-action of medicine dissolving device, are fully smashed and are dissolved, and polyacrylamide solution is finally conveyed into storage bin by conveyance conduit.
The solution preparing should not be crossed long storage time, in storage bin, should adopt stirring at low speed.
the present invention has following characteristics:
(1) can avoid the generation of bulk floc sedimentation and " flake ", polyacrylamide is fully dissolved, in water, content is even, to give full play to its various functions.
(2) dissolution velocity is fast, and efficiency is high, can make at short notice polyacrylamide be dissolved fully, is conducive to increase economic benefit, economizes on resources.
(3) shorten mixing time, avoided polyacrylamide to occur the problem of molecular chain rupture, save the energy, further reduce production costs.
(4) medicament of having avoided producing due to bulk floc sedimentation and " flake " is wasted and line clogging problem.
(5) apparatus structure design is ingenious, takes up an area littlely, operates simple and easy.
