Abstract
The invention relates to a safety high-temperature and high-pressure reaction vessel sealing structure for solvothermal synthesis, belongs to the field of solvothermal synthesis application and aims at solving the technical problem of providing the solvothermal high-temperature and high-pressure reaction vessel sealing structure capable of relatively well integrating the sealing property and the safety. According to the technical scheme, the safety high-temperature and high-pressure reaction vessel sealing structure for the solvothermal synthesis comprises a vessel body 1, a vessel cover 2 and a sealing pin 3; the vessel body 1 and the vessel cover 2 are connected and fastened by threads, the sealing pin 3 is compacted by the vessel cover so as to realize the conical sealing between the sealing pin 3 and the vessel body 1. The safety high-temperature and high-pressure reaction vessel sealing structure for the solvothermal synthesis is mainly used as a safety high-temperature and high-pressure solvothermal synthesis reaction container applied in the field of the solvothermal synthesis of a nanomaterial and other materials under the high-temperature and high-pressure conditions, and also can be used as a digestion tank appiled in the fields of quality testing, drug testing and food testing under the high-temperature and high-pressure conditions. The safety high-temperature and high-pressure reaction vessel sealing structure for the solvothermal synthesis has the beneficial effects of being capable of guaranteeing the safety of the high-pressure reaction vessel for the solvothermal synthesis, avoiding extreme accidents of explosion and the like as the pressure in the high-pressure reaction vessel exceeds the pressure-proof safety value in a metal material, and solving the safety and sealing problems.
Description
Technical field
The invention provides the high-temperature high-pressure reaction kettle hermetically-sealed construction that a kind of safe solvent heat synthetic reaction is used.
Background technology
At present, solvent heat synthesizes field, high-temperature high-pressure reaction kettle version is complicated, various, the security of its hermetically-sealed construction, reliability, stability and sealing property often can not realize simultaneously, especially wherein security and sealing are in design and the more difficult unification of manufacture view, HTHP lower seal performance well often security exist hidden danger, security performance well often sealing property decline, this problem is perplexing the researcher in the synthetic field of solvent heat always.Than non high temperature autoclave, (temperature is below 240 ℃, pressure is below 20MPa), (temperature is more than 240 ℃ can be up to 650 ℃ for high-temperature high-pressure reaction kettle, pressure can be up to 100MPa more than 20MPa) to manufacture and design requirement very high, under high-temperature and high-pressure conditions, its security and sealing are conflicts, if only consider sealing property, under high-temperature and high-pressure conditions, solvent heat synthetic chemistry reaction easily causes that autoclave internal pressure is too high, the accident of easily blasting in the situation that can not get pressure release; Equally, if only consider security performance, have to reduce the sealing property of autoclave, easily cause the leakage of autoclave materials inside and volatilization under high-temperature and high-pressure conditions, cause compound experiment failure.Aspect Design and manufacture, how solvent heat is synthesized and united by security and the sealing of high-temperature high-pressure reaction kettle, perplexing engineer and the researchers in this field always.
Summary of the invention
The invention provides a kind of safe solvent heat synthesizing high temperature autoclave hermetically-sealed construction, structural design form is compact, simple, easy operating, realize the unification of security and sealing, solved a difficult problem of the synthetic autoclave of current HTHP solvent heat.
The technical solution adopted in the present invention is: solvent heat synthesizing high temperature autoclave hermetically-sealed construction is comprised of kettle cover, kettle and link block.It is characterized in that: the outer of outer, kettle bottom and kettle cover all adopts outer-hexagonal structure, between kettle cover and kettle, adopt to be threaded fasteningly, by kettle cover press seal pin, realize the conical surface seal between link block and kettle; The sealing cone of link block and kettle, its angle of inclination keeps coupling with consistent, and angle is in 20-80 degree scope, and preferred values is between 40-70 degree; Sealing means is not for to need the conical surface of sealing ring directly to contact press seal, produces deformation fit tightly by the smooth conical surface of metal under high pressure, reaches sealing purpose, can guarantee sealing under high-temperature and high-pressure conditions and air tight.
Beneficial effect: the present invention is the synthetic field of the solvent heat under the high-temperature and high-pressure conditions of nano material and other materials mainly as the HTHP solvent heat synthetic reaction container application of safety, also can be used as counteracting tank under high-temperature and high-pressure conditions and for quality inspection, medicine inspection and Food Inspection field.Because of kettle cover, link block, kettle three is individual member, kettle cover by the screw threads for fastening with certain pressure deformation function on kettle press seal pin on kettle sealing cone, thereby reach sealing effectiveness, when hypertonia causes safety problem, by kettle and kettle cover also can be there is metal overvoltage deformation in the link block of the powerful compression from two ends automatically, cause that autoclave inner high voltage gas leaks a part and reduces autoclave internal pressure along sealing cone, ensured the security of autoclave, avoid autoclave internal pressure to surpass the withstand voltage safety value of grasping in metal material and the extreme accidents such as explosion occur, security and sealing have better been unified.
