Description
Technical field
The present invention relates to a kind of gas type winding gas cylinder continuous curing oven that is used for winding gas cylinder is cured PROCESS FOR TREATMENT.
Background technology
The fiber-wound gas cylinder manufacture craft in last century the forties at first be applied to the U.S., it mainly is used in the military project aspect, since the fiber winding process economically with technical superiority, also develop simultaneously corrosion-resistant cylinder, gas transmission pipeline and the pressure vessel etc. used as petroleum industry, chemical industry to civilian direction.
To be wound into the steel cylinder surface according to certain rule through the continuous fiber of impregnation, be solidified into the method for goods then, be called the fiber winding process.Composite gas cylinder with winding method obtains has following characteristics: straightening of fibers, direction marshalling, accuracy height in accordance with regulations, can give full play to the intensity of fiber, so specific strength and specific stiffness are all higher.Because it is can design with the realization equal strength, thereby rational in infrastructure according to direction, level and the quantity that load requires to determine fiber architecture.In general, the gas cylinder of glass fibre is compared with the steel gas cylinder with volume, and weight can alleviate a lot.
Winding finishes to be cured and could form the goods with requirement performance.Hot setting resin system product is generally at the stove internal heating curing.Winding gas cylinder is rotated to guarantee that goods are heated evenly, avoid resin before curing, to flow to a side simultaneously.The curing system directly influences the state of cure of resin system and the intensity of winding product.Reasonably the curing system should be according to the taking all factors into consideration of factors such as resin formula, product properties requirement, size, structure, and determine by test in conjunction with practical experience.
In general, through behind the solidification process, resin system can not all be converted into insoluble cured product.Promptly can not make goods reach 100% state of cure.Usually, state of cure is above thinking more than 85% that goods have cured, and can satisfy the instructions for use of mechanical property.But the ageing-resistant performance of goods, hear resistance etc. do not reach its due performance indications as yet fully.On this basis, the state of cure of raising composite can make chemical resistance, heat distortion temperature and the case hardness of composite product improve.But impact strength, bending hardness and hot strength have decline slightly.Therefore, to the goods that different performance requires, even adopt identical resin system, its curing system should be not just the same yet.
After the curing system is determined, should also be noted that two problems: the one, the temperature rise period is wanted steadily, and the intensification speed ratio should be too not fast, otherwise because reaction is too fierce, and low-molecular material fiercenesses such as solvent are overflowed and are formed a large amount of steam bubbles.Another problem is that the cooling cooling will slowly, evenly cause defectives such as crackle occur in order to avoid produce internal stress.
Winding gas cylinder is a kind of load-carrying construction of having relatively high expectations.Have only the failure mode and the stress distribution that scientifically design it, strict its technology controlling and process key element of control just can produce safe winding gas cylinder.
Existing winding gas cylinder curing apparatus is the clearance-type heating furnace mostly, and the type of furnace generally adopts car-type or case structure.Every stove can only be adorned a winding gas cylinder, and be that the curing that is used for bigger winding steel cylinder is handled, hot air circulation blower places the body of heater side, and the thermal source that is used to heat is all from direct heating, gas-fired heater particularly, the waste gas that produces behind the resin solidification directly enters in the atmosphere.This curing apparatus production efficiency is low, energy resource consumption is big, environmental pollution is serious.
Summary of the invention
Technical problem to be solved by this invention provides the high winding gas cylinder continuous curing oven of a kind of production efficiency;
Another technical problem to be solved by this invention provides a kind of winding gas cylinder continuous curing oven of energy savings.
For solving the problems of the technologies described above, the invention provides a kind of gas type winding gas cylinder continuous curing oven, comprise being used for the curing oven body of heater that winding gas cylinder carries out heat treated, it is characterized in that: also comprise driving the transmission system that winding gas cylinder moves and self rotatablely moves forward in the curing oven body of heater; Make the hot air circulating system that keeps certain temperature in the curing oven stove and make uniformity of temperature profile in the stove; To carrying out temperature, pressure controlled blind controller system with hot air circulating system in the stove; For described transmission system and hot air circulating system provide the electric control system of power, described transmission system comprises: be positioned at the curing oven body of heater entrance point, be provided with the material loading portion of stock shelf; Be positioned at the transition part of the port of export of curing oven body of heater; The discharging portion adjacent with transition part; Run through the rotating link chain portion that the driven winding gas cylinder that is positioned at material loading portion, curing oven body of heater and transition part rotates; The proal chain of the driven winding gas cylinder portion of running through the material loading portion that is positioned at, curing oven body of heater, transition part and discharging portion.
The beneficial effect that the present invention reached:
By the structural design of above each system, the curing of winding gas cylinder handled can realize continuous production, improved production efficiency, adopt hot air circulating system to keep the uniformity of temperature in the stove simultaneously, and can make the energy recycling, and saved the energy, reduced production cost.
