Description
Technical field
The invention belongs to rubber product processing technology fields, and in particular to a kind of rubber product extraction device and extracting side
Method.
Background technique
Rubber product is mainly vulcanized by substances such as raw rubber, filler, vulcanizing agent and pigment, due to that can add in these components
Add some substances for being easily worked rubber, these substances are for pharmaceutical rubber product, during with medicament contact, hold
It is easy to migrate to come out, cause the compatibility of rubber product unqualified.Therefore, in order to improve the compatibility of rubber product and drug,
The substance migrated out is easy in rubber product, the method by extracting in lye keeps the cleanliness of product higher.
Currently in Chinese market, infusion has carried out alkali density with gasket, but this extracting to pharmaceutical rubber product and
It says and is not suitable for.The shape of one side gasket is at plane, compared with rubber product, very light in weight, and even if lye flowing is not so good,
Also it is less susceptible to generate local concentration difference and overstocks the impression formed, on the other hand infusion gasket, with pharmaceutical rubber product
Difference is not directly to contact with drug, therefore about the homogeneity for extracting quality and inherent cleanliness, producer is not to close very much
Note, does not also require.And pharmaceutical rubber product is different, because directly contacting with drug, the homogeneity of quality is by client
Very big concern, the extracting tank for being accordingly used in infusion gasket is not suitable for pharmaceutical rubber product, makes a general survey of domestic market, also
Do not have a for extracting the extracting tank of pharmaceutical rubber product.
In consideration of it, in view of extraction effect can greatly improve the inherent cleanliness of rubber product, while Japanese market really
Medical product largely all carried out alkali density, later by the market discovery of consulting Japanese market extracting tank, price is remote
Much higher than domestic extracting tank price, many pharmaceutical rubber product enterprises is allowed to hang back.
Chinese patent CN102702587A discloses a kind of injection synthetic polyisoprenes rubber plug and preparation method thereof,
It is directed to the extraction process of polyisoprene rubber plug, is to cause the flowing of lye by the mode of pressure release, but gather
Smaller (the 0.9-1.1 g/cm of the density of isoprene rubber plug3), the buoyancy in lye is big, and polyisoprene rubber plug is disk
Formula is not allowed to be also easy to produce impression, and therefore, which is only applicable in light weight and is not likely to produce the rubber product of impression.
Chinese patent CN104307198A discloses a kind of efficient method for extracting of butyl glue gasket of low power consuming, is to use
Start exhaust after keeping the temperature 40 minutes to be depressured, insulating process is there is no deairing step and only carries out once being depressured i.e. completion extracting work
Make, be equally the rubber product of sheet is stripped not allow to easily cause impression, and its be directly added into extracting tank it is pure
Then water is heated to extraction temperature with steam, since pure water needs to heat for a long time from room temperature to extraction temperature, the patent
Heating efficiency is low, is not to improve the effective heating means of extraction efficiency.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of big (flat suitable for rubber product especially density
Equal density is 1.2-1.4g/cm3), be also easy to produce impression rubber product (such as butyl rubber bung) extraction device and method for extracting,
By contactless agitating method, the pressure on rubber product surface caused by rubber plug is overstock in lye due to long-time is avoided

2/3rds, then hang in vertical extracting tank, using material cage ontology on cylindrical protrusions be stuck in extracting tank tank interior
Card slot in will expect that cage is fixed on extracting tank tank interior, finally by the lid of extracting tank and tank body sealing；
(2) inlet valve is opened, is passed through the feed water through over-heat-exchanger, the water level for reaching setting is automatically stopped；
(3) unlatching steam inlet valve is passed through steam and heats up to extracting tank, and when being warming up to 95 DEG C -100 DEG C, it is empty to open compression
Gas intake valve is passed through 20 ~ 35s of compressed air, stirs once to rubber product, and the pressure of the compressed air is 3-8kg；
(4) steam off intake valve when continuing to be warming up to 121-125 DEG C, pressure maintaining 40-60min, in pressure maintaining period, every 5-10
Minute opens inlet valve 20-40 s or compressed air inlet valve 20-40s or successively opens inlet valve 20-40 s and compressed air
Intake valve 20-40 s successively opens compressed air inlet valve 20-40 s and inlet valve 20-40 s, stirs rubber product
It is dynamic；
(5) it after the completion of pressure maintaining, opens exhaust valve and enters pressure release program, when pressure is down to 0MPa, open on extracting tank lid
Then manual exhaust valve opens the lid of extracting tank, hang out material cage, and extracting work is completed.
9. the method that extraction device according to claim 8 is stripped rubber product, it is characterised in that: the step
(2) and the feed water in step (4) be the sodium hydroxide that mass concentration is 0.1-0.25% aqueous solution, wherein warp in step (2)
The temperature of the feed water of over-heat-exchanger is 90 DEG C, and the feed water in step (4) after unlatching inlet valve is high pressure back-flushing, institute
The flow for stating high pressure back-flushing is 2.5-6.3m3/ h, the lift for providing the high-pressure hydraulic pump of high pressure back-flushing is 32-80m.
