Description
Technical field
The equipment used the invention belongs to chemical field more particularly to a kind of reaction kettle.
Background technique
The broad understanding of reaction kettle has the container physically or chemically reacted, is designed by the structure to container and is matched with parameter
It sets, realizes the mixed function for heating, evaporation, cooling and the low high speed that technique requires.
Reaction kettle is widely used in petroleum, chemical industry, rubber, pesticide, dyestuff, medicine, food, for complete vulcanization, nitrification,
Pressure vessel of the technical process such as hydrogenation, hydrocarbonylation, polymerization, condensation, such as reactor, reaction pot, decomposition pot, polymeric kettle etc.；Material
Matter generally has carbon manganese steel, stainless steel, zirconium, Ni-based (Kazakhstan, Monel, inconel) alloy and other composite materials.
Reaction kettle is comprehensive reaction vessel, the design according to reaction condition to reaction kettle structure function and configuration attachment.From
Charging-reaction-discharging of beginning can complete pre-set reaction step with higher the degree of automation, to reacting
The important parameters such as temperature, pressure, mechanics control (stirring, air blast etc.), reactant/product concentration in journey carry out stringent tune
Control.Its structure is generally made of autoclave body, transmission device, agitating device, heating device, cooling device, sealing device.It is corresponding mating
Ancillary equipment:Still, condenser, water segregator, collecting tank, filter etc..
Reaction kettle is made of autoclave body, sealing cover, collet, blender, transmission device, gland seal device, bearing etc..Agitating device
When ratio of height to diameter is larger, multiple impellers leaf can be used, can also arbitrarily be matched acording to the requirement of user.Collet is set outside kettle wall, or
Heat-transfer surface is set in device, can also be exchanged heat by outer circulation.Fulcrum bearing has supporting type or hanging support etc..Revolving speed is more than
160 turns or more preferably use gear reduction unit the number of openings, specification or other requirements that can require design, production according to user.
The sealing cover of reaction kettle is one of critical component of reaction kettle, the opening for reaction kettle.Existing sealing cover is
The leakproofness of reaction kettle is improved, often design is very cumbersome, and opening and closing is complicated；And it cannot achieve gradually after experiment
Pressure release is easy to produce danger.
Authorization Notice No. is CN207169673U, and authorized announcement date is that the Chinese utility model patent on April 3rd, 2018 is public
A kind of sealing cover and reaction kettle for reaction kettle is opened comprising for being sealed on sealing reaction kettle opening in reaction kettle opening
Lid, lid top is equipped on the lid central axes for applying axial thrust to lid to force lid sealing gland to exist
Force application mechanism in reaction kettle opening, force application mechanism include the screw rod for being connected to lid upper surface, are threadedly connected on screw rod and use
Axial opposed a pair of of active force is formed between lid to force limiting card of the lid sealing gland in reaction kettle opening
Platform and be threadedly connected on screw rod for limit between chuck and screw rod relatively rotate locking lock-nut.Existed using screw thread
Axially reverse a pair of of active force is constituted between limit chuck and lid, so that lid axial direction gland be forced to be open in reaction kettle
On, to realize the opening sealing of reaction kettle.Structure is simple, highly-safe, suitable for the various reaction kettles with seal request
It uses.But there is also following shortcomings for the utility model：
1, lid is tightly pressed at instead by the effect that the sealing of the utility model relies primarily on positive stop lug boss, screw rod and lock-nut
It answers in the opening of kettle, to have the function that sealing, the pressure in reaction kettle is directly acted on lid, once positive stop lug boss, spiral shell
Bar and lock-nut slightly limit it is not in place will result in gas leakage, the effect of sealing is not achieved, to positive stop lug boss, screw rod and locking
The position-limiting action of nut requires very high.And the sealing of lid is relied solely on, sealing effect is not very good.
2, it needs to manually control strength mechanism to exert a force to lid, so that lid is pressed in the opening of reaction kettle, to reach
The purpose of sealing, this mode is very laborious for operator, and its dependence is positive stop lug boss and screw rod and lock
Only the effect of nut limits lid in the opening of reaction kettle, when pressure is biggish in reaction kettle, to positive stop lug boss and
The reaction force of screw rod and lock-nut is big, will result in the damage of positive stop lug boss and screw rod and lock-nut after long-time service,
Lose position-limiting action.
