Background technology
Produce take plastics as raw material in the process of all kinds of manufactured goods, no matter raw material is virgin material or feed back, wherein more or less must be mixed with all kinds of impurity.In the plastic extrusion process, plastic melt is through plastifying for a long time and being heated in addition, and melt will produce residue.Impurity in these raw material and residue in case enter in the extrusion die, will cause flow blockage or product defect, affect continuity, the stability of manufactured goods quality and production, even production can't be carried out at all.In order to eliminate these particulate contamination, make pure melt successfully enter extrusion die, and the goods of acquisition high-quality, so must between extruder screw head and mould, place screen pack, along with the continuity that finds time, will pile up increasing dirty thing on the screen pack, this moment, fusion pressure raise, and melt flow descends, when surpassing certain fusion pressure, screen pack is broken up or is stopped up and lost efficacy, and just must change screen pack.Filter filtration decontamination also requires in use to change easy, quick simultaneously, keeps production during replacing continuously, tries one's best and reduces production pause and the waste product generation that therefore causes.Common filter is in process of production when impurities accumulation arrives to a certain degree; the needs shutdown just can replace with new filter screen or screen pack is cleaned out; because the difference between raw material is large; when the more product of processing impurity; screen pack needs frequent; cause production line also to need to shut down frequently, so that production efficiency reduces greatly.
Now invention has board-like, and column type, net belt type etc. are not shut down filter, but still have following problem:
Problem 1: the board-like or column type filter of single channel can not be realized continuous draping when changing screen pack, produces the variation of pressure and melt temperature when causing draping, affects product quality.Automatically do not clean filter net device, therefore behind filter net jam, need to take out to clean inconvenient operation.
Problem 2: dual channel runner board-like or the column type filter is long, easily residual, at output hour, stops up after the mass flow discrepancy that is prone to two runners causes a runner longevity of service.Internal structure is complicated, and difficulty of processing strengthens, and cost raises, and does not have and can not automatically clean.
Problem 3: the net belt type filter can be realized continuous continual draping; but automatic cleaning and filtering net; waste to screen pack is serious; and the screen belt of filter need replace with new guipure after using again; this Renewal process needs shutdown operation, has influence on the production efficiency of product.
Summary of the invention
In order to solve the deficiency of background technology, the purpose of this utility model is to provide a kind of blowing melt automatic cycle net filtration device, adopts the cleaning device realization to cleaning and the replacing of filter screen, satisfies and does not shut down the requirement that continuous draping is cleaned automatically.
The technical scheme that its technical problem that solves the utility model adopts is:
The utility model comprises outer filtration plectane, inner filtration plectane, screen pack, advances melt chamber, goes out melt chamber, two cooling water pipes and cleaning device; Between outer filtration plectane and the inner filtration plectane screen pack is housed, advance melt chamber, go out melt chamber and be arranged on screen pack ring both sides, cleaning device is arranged on a side of screen pack ring, and two cooling water pipes are installed in respectively on the flange face of cylinder of melt chamber and the close screen pack that goes out melt chamber.
Described cleaning device comprises cleaning felt axle, shower nozzle, case shell, cleans the felt axle and is installed on the axis hole of case shell front and back, and shower nozzle is installed in case shell upper surface center, aims at and cleans the felt axle; Clean the felt axle and contact with screen pack one side, clean when the felt axle rotates and to drive the screen pack rotation.
Described outer filtration plectane annular has annular groove in its hole; Described inner filtration plectane is circular, has annular groove on its external cylindrical surface; Screen pack is installed in two grooves of outer filtration plectane and inner filtration plectane, and screen pack can be along freely circling round in two grooves.
The beneficial effect that has of the present utility model is:
Blowing melt automatic cycle net filtration device of the present utility model adopts the screen pack of annular, realizes the replacing of screen pack by cleaning felt axle rotation drive screen pack motion in filtering the plectane groove of cleaning device.Need not shut down when changing screen pack, and uninterrupted continuously, thereby the flow velocity of input and output material and pressure have also reduced the generation of substandard products without significant change when enhancing productivity.This external enwergy is automatically cleaned screen pack and is realized recycling of screen pack, saves material, saves time.
