Description
Technical field
The invention belongs to the high molecular materials such as plastics, chemical fibre, rubber, melten gel production and product molding processing technique field,
More particularly to a kind of drum-type large area is without fluctuation fondant filter.
Background technology
In the production of the high molecular materials such as plastics, chemical fibre, rubber, melten gel and product molding process, the drop in material
Solution object and impurity can influence the quality of product or form waste product, and plasticizing filter device would generally be arranged in production line thus.With
The continuity of production time, the impurity in melt is gradually accumulate on filter element, to cause system pressure to increase, under flow
Drop, host energy consumption increase.When more than certain pressure, filter element will be broken up and failed, or even cause equipment damage, because
This should just replace strainer when system pressure reaches a suitable safety value.It must just be shut down according to original old device operation
It is artificial to replace filter element, from form removal tool, flange, cleaning, the filter element more renewed, again installation heating, traction embryo material to
Normal production, causes the loss, energy waste, yield of raw material to reduce, worker at whole process few then dozens of minutes, at most several hours
Busy fatigue is operated, is interrupted even if will also result in product using certain quick net-changing device devices for not tearing machine open, material, energy wave
Take.For this problem, domestic and international relevant enterprise has carried out a large amount of research and improvement to filter element.
German Will-Man(Wei Man)Polymer filtration company, Scheer(Shu Er)Company and Austria Erema(It is angstrom vertical
Agate)Company sequentially develops single channel single plunger quick net exchanging filter element and binary channels double plunger does not shut down net-changing device and crosses filtering element
Part, can not shut down draping, screen replacing stream material pressure fluctuation it is big, complicated, the former be best suited for earnestly be granulated production, the latter
It is suitable for the basis processing of the raw materials such as PE, PP.German Genness(Ge Nuoyisi)The RSF types rotation of equipment and technology company exploitation
Disc type filter element, the automatic draping of energy, arteries and veins flushing net, stream, material pressure is stable, it is small to fluctuate, and cannot be kneaded to solution, knot
Structure is complicated, and there is a strainer in when work outside the main body always, and exposure can cause cleaning dirty remnants to strainer in air for a long time
Carbonization qualitative change occurs for material, and subsequent product quality can be influenced after output.German Barmag(Ba Mage)Company, Austria Lenzing
(Lenzin)The single channel guipure of company's exploitation is automatic fitration element, it can be achieved that automatic draping, strainer is special, resistance to force down, draping
Period is long, uneconomical.
Only it is to be added in extruder flange and machine for a long time for the mating filter of China's plastic products extruding production line
One block of porous plate between head flange and several strainers replace strainer and need to shut down mutual disassembly, bothersome laborious, study and improve
Filter never obtains enough attention.In recent years, filter technology development is very fast, but the performance of filter is still poor, from
The problems such as dynamicization degree is low, material pressure stability is poor, is not achieved the manufacturing technique requirent of high quality of products.From international filter technology
The China Shang Jiang is in compared with backward technology level, and medium and small type filter, which can meet, is normally applied requirement, but is matched in large-scale squeeze
Going out the filter of machine far can not also meet the requirements.
Invention content
The present invention provides a kind of drum-type large area without fluctuation melt filtration to solve shortcoming in the prior art
Device, filter of correcting one's mistakes overcome domestic and international fondant filter device and generate big material pressure fluctuation, temperature during replacing strainer not
, web plate needs cleaning, the shortcomings of material is oxidizable, overall volume is big, realization can be facilitated to automatically control, stepping update strainer,
Update strainer is simple, efficient and convenient, stream is stable, avoids material is exposed carbonization qualitative change occurs in air, in same filtering surface

Effect.
The melt by feed inlet in the present invention is radially dual channel structure, and two panels strainer is symmetrical simultaneously opposite
Work can get three big advantages in this way:(1), filter area doubles, and task performance is high, longevity of service;(2), two is symmetrical opposite
The resultant force of material pressure that work strainer is subject to is zero, the turbulator rod and inner cylinder outer circumference in inner cylinder centre bore not by unbalance loading,
In draping, pivoting friction resistance is small, driving force is small, and amount of friction is small, long lifespan;(3), only there are one filters with rotating disc type filter
Net work is compared, same rotation one week, installs 1 times less of melt residence time in filter screen slot, does not easily cause raw material filtering aging.
Strainer on middle cylinder body periphery is all closed in inside inner cylinder, has the advantages that three is big:(1), melt not with air
Contact prevents melt carbonization rotten;(2), heat insulation effect is good, energy saving, temperature is uniform;(3), the orifice plate at filter opening after working is not
It need to calcine cleaning, it is saving of labor, material-saving, energy saving.
In conclusion the present invention uses the three layers of tube structure and strainer carrier of drum forms, leaf filter knot is compared
Structure has following obvious advantage:(1), mechanical structure is good, height expect pressure under deform it is small, be not easy material leakage failure;Leaf filter knot
Structure is extremely difficult to this point;(2), specification circle geometry is easy to process, is easy to ensure that precision, processing cost are low;(3), it melts
Material is not contacted with air, prevents melt carbonization rotten;(4), heat insulation effect is good, energy saving, temperature is uniform;(5), strainer is distributed in circle
In the peripheral surface of cylinder, the strainer gross area is 3-8 times big compared with the filter of equal volume or weight, and filter capacity is notable
It improves.
The present invention can online draping, stream is stable, filter area large volume is small, properties of product are stablized, volume increase, energy saving, drop
Consumption, saving of labor improve the degree of automation of production line, and it is horizontal to improve industry overall technology.
The present invention creatively has devised drum-type overall structure on the basis of the research and development of decades processing.It both collected
The advantages of can not shutting down continuous draping at existing advanced filter, and overcome existing filter and exchange strainer pressure oscillation
Greatly, the shortcomings of temperature is uneven, web plate needs cleaning, material is oxidizable;It can also facilitate and realize stepping update strainer.This is revolutionary
Innovative design, new type auto filter off in China will be made to cross the forefront in the world, international most advanced level is arrived, greatly improve
The industrial grade of China's macromolecule mechanical industry, enhances competitiveness in the international market, and economic results in society are huge and notable.
