Description
Technical field
The utility model belongs to chemical industry equipment manufacturing technology field, relates to a kind of equipment producing sulphur.
Background technology
Along with developing rapidly of automotive industry, the safety issue of tire is subject to increasing attention, and most important safety issue is exactly delamination and blows out.Tire belongs to layer structured articles, and between each layer, powerful not blowing out with the not delamination of uniform bonding guarantee tire, needs to add vulcanizing agent for this reason and carry out crosslinking reaction.Only have and adopt high-quality high-quality vulcanizing agent, carry out appropriate vulcanization reaction simultaneously and could realize effective bonding.The vulcanizing agent generally adopted at present is insoluble polymerization sulphur.There are three large technical bottlenecks in the production of insoluble polymerization sulphur in the world: use a large amount of noxious solvent, danger high, be difficult to realize green production; Polymerisation conversion is low, and domestic production technical transform rate is about 40%, and the transformation efficiency of advanced foreign technology also only reaches 70%; Poor high temperature stability.
Theoretically, current processing method cannot produce high-temperature stable, high-quality polymerization sulphur.The polymerization sulfur product of preparation quality excellence, the major objective of Shi Ge Tire production state tackling key problem all the time.
Domestic polymerization sulphur market capacity is 100,000 tons, underproduce 30,000 tons, and is low-quality product, the more important thing is no blooming, poor heat stability, has a strong impact on qualification rate and the security of tire, can not adapt to the processing requirement manufacturing high-quality tyre.Therefore, be badly in need of that Development and Production technique is green, productive rate is high and there is the polymerization sulfur product of high-temperature stability, to adapt to the demand of people to high-quality, high security tire, thus more effectively ensureing the life security of people.
In view of the demand manufacturing high-quality tyre, along with the development of China's Tire production industry, the preparation of the insoluble polymerization sulphur of China forms industry, the existing professional production enterprise 34 in the whole nation, wherein 6 enterprise's production capacities reach 1 kiloton, and whole industry throughput reaches 30,000 tons.Within 2011, domestic polymerization sulphur total amount is about 1.5 ten thousand tons.The not releasable factor of domestic polymerization sulphur production capacity is a lot, and major cause is that China's polymerization sulfur cream mostly adopts scorification, and this method polymerisation conversion is low, causes production efficiency low.In addition, do not grasp advanced production technology, quality product is low, can not yield products of quality, and cannot meet the demand that high-quality tyre manufactures, also limit a large amount of productions of China's insoluble polymerization sulphur.
The more important thing is, from science, the technology such as evaporating method, scorification, contact process of current use, cannot produce desirable polymerization sulfur product.Must in conjunction with tire manufacturing process, start with from the Molecular Structure Design of polymerization sulphur, carrying out research to preparation principle makes it have more scientific rationality, Innovative process technology could overcome the three large technical bottlenecks that current polymerised sulphur is produced completely, improve the manufacturing integral level of China's polymerization sulphur, and then improve the integral level of China's Tire production industry.
The current polymerization sulphur produced in the world is insoluble polymerization sulphur.The production method of insoluble polymerised sulphur mainly contains evaporating method, scorification, contact process etc.Evaporating method, after the sulphur of drying being heated to 110 DEG C-160 DEG C fusings, continuing to be warming up to 500 DEG C-700 DEG C and produce superheated vapo(u)rs, then be ejected in quench liquid and cool rapidly, can obtain the mixture being polymerized sulphur and sulphur, then use dithiocarbonic anhydride (CS
2) solvent extraction, using not dissolving partly as effective product wherein, be called insoluble polymerization sulphur.Evaporating method transformation efficiency is high, but high to equipment requirements, dangerous large.The domestic scorification that generally adopts is polymerized.Sulphur melting at 120 DEG C, when being warming up to 160 DEG C, the open loop of original octatomic ring modular construction, form the linear chain structure that relative molecular mass does not wait, at 220 DEG C, after reacting further, add a certain amount of stablizer and close the end of the chain, through quenching liquid chilling, after being washed to neutrality, dry, pulverize to 80 ~ 100 orders, obtain the insoluble polymerization sulphur of content about 40%, finally use CS again
2solvent extraction obtains the insoluble polymerization sulphur of high-content as far as possible.The production technique of polymerization sulphur is different, and the productive rate that sulphur changes into insoluble polymerised sulphur is different.The transformation efficiency of the polymerization sulphur that domestic scorification is produced is mostly about 40%, and advanced foreign technology polymerization sulfur conversion rate also only reaches 70%.
Our company develops a kind of solubility polymerization sulfur cream technique, but due to the singularity of adopted raw material, existing equipment cannot utilize.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of equipment producing solubility polymerization sulphur.
The utility model is primarily of kettle, stir shaft, electric motor, duplex agitating vane, spatula, scrape chain, water jacket, electric heater, temperature sensor and control indicating meter are formed, kettle is stamped opening for feed, discharge port is stamped under kettle, kettle has axial stir shaft, stir shaft is arranged on kettle by the bearing being located at kettle upper and lower covers, stir shaft connects electric motor, duplex agitating vane stir shaft is equipped with, spatula is had close to kettle lower cover place bottom stir shaft, duplex agitating vane outer end has axial scrapes chain, outside kettle, water jacket is installed, water-in is arranged at the bottom of water jacket, water outlet is arranged at the top of water jacket, water jacket is built with electric heater and temperature sensor, electric heater and temperature sensor connection control indicating meter respectively, control indicating meter outside at kettle.Material can be stirred from bottom to top by duplex agitating vane and stir, spatula and scrape the material that chain can wipe the inwall being pasted onto autoclave body bottom off, by the material carrying out reacting in the water heating kettle in electric heater heating water jacket, when temperature sensor monitors is too high to temperature of reaction, lower the temperature by changing cold water.Present device is for tough feature design in materiel machining process, and duplex agitating vane, spatula and scrape the emphasis that chain is design, temprature control unit is then the routine techniques of reactor.
