Description
Technical field
The utility model relates to the chemical industry equipment field, is specially a kind of cohesion after-treatment device for cis-1,4-polybutadiene rubber or solution polymerized butadiene styrene rubber production.
Background technology
Along with China's rapid development of economy, living standards of the people improve constantly, and the domestic automobile industrial development is rapid, and automotive industry has become one of mainstay industry of China at present, country continues to improve the developing of automobile industry level, cultivates the consumption market based on the private consumption.China's automobile industry development planning is put into effect, and the policy of a series of stimulation automobile consumptions that match with it or is soon put into effect, and these all are conducive to guarantee increase in the year that keep about 10% in Chinese automobile market.The development of automobile industry will be conducive to increase domestic elastomeric demand.Styrene-butadiene rubber(SBR) (SBR) is a kind of general purpose synthetic rubber that output is the highest in the world, consumption is maximum at present, wherein solution polymerized butadiene styrene rubber (SSBR) accounts for 7.01% of world's synthetic rubber overall throughput, SSBR is in stage of steady development, and rate of growth is very fast, is SBR development priority from now on.Solution polymerized butadiene styrene rubber (SSBR) is that divinyl and vinylbenzene adopt organolithium to cause anionoid polymerization in varsol and the multipolymer that makes.Because advantages such as that it has is wear-resisting, cold-resistant, heat generation is low, color and luster good, ash content is few, purity is high and vulcanization rate is fast, very fast in developed country's development in recent years, along with popularizing of tire meridianization, especially the development of novel energy-conserving radial, tire is had higher requirement with glue, not only require the rubber strength height, anti-slippery is good, also requires resistance to flow low.Solution polymerized butadiene styrene rubber has had the over-all properties that anti-slippery is good and rolling resistance is low concurrently, it is the suitable sizing material of all-year tire, can satisfy tire at a high speed, safe, energy-conservation, comfortable requirement, tire drag with its manufacturing is low, wet-sliding resistant performance is good, wear resisting property is good and living heat is low, has become to make radial-ply tyre and the requisite important source material of high-performance tire.Cis-1,4-polybutadiene rubber is the second largest glue kind that is only second to styrene-butadiene rubber(SBR) in the world at present, account for 23.03% of world's synthetic rubber overall throughput, its principal feature is that wear resistant excellence, flexible resistance are good, rebound resilience is good, hysteresis loss is little, it is hot low to give birth to, low-temperature performance good.Cis-1,4-polybutadiene rubber general and other glue kind and usefulness for the manufacture of various parts such as tire tread, sidewall and carcasses, also are used for the manufacturings of adhesive tape, sebific duct, rubber overshoes and other mechanicals.At present homemade SSBR and the quality of cis-1,4-polybutadiene rubber are also unstable, technical indicator does not satisfy requirement yet, its reason just is that the design of technology, equipment is also not too reasonable, such as cis-1,4-polybutadiene rubber and solution polymerized butadiene styrene rubber after polyreaction, agglomeration process, need carry out aftertreatment, reduce the moisture content in the product, present back place device design is complicated, and power consumption is big.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of cohesion after-treatment device for cis-1,4-polybutadiene rubber or solution polymerized butadiene styrene rubber production is provided, and it can solve the complicated and big defective that consumes energy of prior art design.
The concrete technical scheme of the utility model is: comprise the vibratory screening apparatus, dehydration extrusion expansion all-in-one and the fluidized drying case that connect successively; The vibratory screening apparatus bottom is connected with hot-water cylinder respectively with dehydration extrusion expansion all-in-one bottom, and hot-water cylinder top is provided with overflow port and connects every Jiao Chi; Fluidized drying case bottom is provided with pipeline and connects well heater and blower fan successively.
Such scheme can further be improved to: describedly be provided with pipeline and pump every Jiao Chi and connect the cohesion still; Described well heater is for adopting the well heater of low-pressure water steam.
The utility model is simple in structure, reasonable in design, can carry out drying treatment fast, reduce the moisture content of product, and it is relatively low to consume energy.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, a kind of cohesion after-treatment device for cis-1,4-polybutadiene rubber or solution polymerized butadiene styrene rubber production comprises the vibratory screening apparatus 1, dehydration extrusion expansion all-in-one 2 and the fluidized drying case 6 that connect successively; Vibratory screening apparatus 1 bottom is connected with hot-water cylinder 3 respectively with dehydration extrusion expansion all-in-one 2 bottoms, and hot-water cylinder 3 tops are provided with overflow port and connect every glue pond 4, is provided with pipeline and pump 9 connection cohesion stills 5 every glue pond 4; Fluidized drying case 6 bottoms are provided with pipeline and connect well heater 7 and blower fan 8 successively, and well heater 7 is preferably the well heater that adopts the low-pressure water steam.
Its working process is: micelle water is from condensing still by being pumped to vibratory screening apparatus 1, in vibratory screening apparatus 1, part water is separated, the rubber powder that in the water of separating, has trace, the water of separating and rubber powder flow into hot-water cylinder 3, and the micelle that comes out from vibratory screening apparatus 1 then enters dehydration extrusion expansion all-in-one 2, the micelle devolatilization that is dried in dehydration extrusion expansion all-in-one 2, the water of extruding flow to hot-water cylinder 3, and micelle enters fluidized drying case 6 and further removes moisture.
Hot-water cylinder 3 is the containers that band stirs, and can make part rubber powder and the overflow of part water extremely every Jiao Chi, and water is by recycling in the cohesion still that is pumped to the cohesion unit then.
Fluidized drying case 6 is horizontal vibration conveyors that have porous plate, is used for the product insulation and reduces moisture content to prescribed value by the hot blast under the porous plate, and hot blast is by blower fan 8 and adopt the well heater 7 of low-pressure water steam to provide.
For those skilled in the art, under the prerequisite that does not break away from the utility model principle, might be to concrete size, perhaps local structure are made some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
