A kind of paddle of adjusting paddle height and adopt the reactor of this paddle
The utility model relates to field of chemical equipment, particularly relates to a kind of paddle of adjusting paddle height, and adopts the reactor of this paddle.
Reactor is reaction pot again, being a kind of common container for physics or chemical reaction, being provided with for stirring, the paddle that accelerated reaction is carried out in it.Reaction solution, under the effect of paddle, mixes, reacts in reactor.
The type of paddle is a lot, and its difference is main on blade.The classification of blade, can divide the flow pattern that fluid matasomatism produces according to blade, blade can be divided into two types-axial-flow type blade and radial-flow type blade.So-called axial-flow type blade, refers to that the main discharge opeing direction of blade is parallel with shaft; Namely screw-pushing type blade is a kind of typical axial-flow type blade; So-called radial-flow type blade, refers to that the main discharge opeing direction of blade is vertical with shaft.
Blade feature: (1) anchor formula, frame are used in the slow-speed of revolution generally between 60 to 300rpm, this is because consider anchor formula, frame length has 3 to 5 meters more, the strong point is positioned at spindle nose, shaft limited strength, lower shaft is beated larger at a high speed, particularly stir bottom shaking amplitude very large, even can encounter reactor inwall.Viscosity simultaneously in conjunction with material chooses revolution, and the large rotating speed of viscosity is low, the high point that the little revolution of viscosity is suitable.(2) turbine type: paddle quantity is many, and kind is many, and rotating speed is high, changes over horizontal motion by movement in vertical direction with making fluid well-distributing.(3) pusher: push type also claims rotary propeller type, be often monoblock cast, when adopting welding, weld with axle sleeve again after die forging, process more difficult.Static balance experiment should be done during manufacture.Available axle sleeve, flat key are connected with axle with holding screw.
Blade selects main material of paying close attention to have a few phase, volume, density, viscosity, mixing requirement etc.Adopting many in prior art is pusher paddle, find in practice, for the material of different viscosities, different requirements is had from the distance bottom reactor to blade, only has the mixing effect that suitable distance just can reach best, such as, when material viscosity is very large, then need blade bottom reactor away from some.
On the other hand, the reaction solution in reactor according to the difference of reactant, and can regulate the injection rate of reaction solution, makes the liquid level of reaction solution be not be fixed on a height.When the liquid level of reaction solution is on the low side, the blade that there will be paddle is not immersed in reaction solution, thus there is the problem can not carrying out stirring.
Publication No. is the reactor that the Chinese patent literature of CN102698694A discloses the adjustable paddle length of kind, it comprises the kettle of hollow, the teeter column of cylindricality is vertically installed with in described kettle, described teeter column can rotate around own axes under the driving of motor being arranged on described kettle top, be connected by the joint pin of dismountable cylindricality between described teeter column with described motor, described joint pin two ends are provided with the flange connecting described screw and described motor respectively.
But the scheme that the document is recorded is that loom is split as multistage, regulate blade from the distance bottom reactor by the length increasing and decreasing loom.All need loom dismounting to reconnect when the program regulates at every turn, operation extremely bothers again.
Utility model content
In order to overcome the defect that prior art exists, the utility model provides a kind of paddle of adjusting paddle height, without the need to dismantling loom and adjustable blade from the distance bottom reactor, simple to operate.
The technical solution of the utility model is: a kind of paddle of adjusting paddle height, comprise outboard part of the oar, the outer cover of described loom be provided with slide axially, the overcoat of circumferential location fit, described blade is fixed on the bottom of this overcoat, the screw top of described loom is combined with regulating sleeve, and the top of described overcoat and regulating sleeve are rotatably assorted and axial location.
Wherein overcoat rotates together with loom with blade, and overcoat along the axially close of loom or can slide away from the bottom of the still of reactor.Described regulating sleeve coordinates with the screw top of loom, rotate regulating sleeve and can make regulating sleeve moving axially along loom, because regulating sleeve be enclosed within axial location outward, rotate regulating sleeve and adjustable overcoat and blade and the distance at the bottom of reactor still, and regulating sleeve and overcoat top are rotatably assorted, when overcoat rotates on regulating sleeve without impact.
Be rotatably assorted as overcoat top and regulating sleeve and a kind of mode of axial location, preferably, the inwall of described regulating sleeve is provided with cannelure, and the top of described overcoat is provided with the flanging of inserting this cannelure.
Described cannelure around loom distribution and the opening of cannelure towards loom.Described cannelure limits flanging moving along loom axis, and when only having rotation regulating sleeve, flanging could move axially along loom, and cannelure does not affect the rotation of flanging simultaneously.
For convenience of inserting in described cannelure groove by described flanging, preferably, described regulating sleeve is divided into the two parts axially cut open, and is fixed together by these two parts by bolt.
Conveniently operating personnel rotate regulating sleeve, and preferably, described regulating sleeve outer wall is provided with the effort handle for rotary regulating sleeve.Described effort handle can be column or ring-type, and object to facilitate hand-held.
In order to ensure that overcoat rotates together with loom, will ensure that overcoat can moving axially along loom, preferably, the outer wall of described loom is embedded with circumferential positioning key, and the inwall of described overcoat is provided with axial channel, and described circumferential positioning key is inserted in this axial channel simultaneously.Described axial channel also can run through sleeve side wall makes circumferential positioning key stretch out the sidewall of overcoat, but considers the sealing of overcoat, avoids material to enter jacket internal, axial channel had better be opened in the inwall of overcoat.
Be enclosed within when axially moving down along loom outward, operating personnel do not note, the excessive jacket bottom that causes of the displacement of overcoat may be made to stretch out loom, preferably, be provided with and prevent from jacket bottom from departing from the anti-of loom raising one's hat or locking pin bottom described loom.
The utility model is also public has driven a kind of reactor, this reactor comprises the kettle and kettle cover that cooperatively interact, described kettle cover has drive motors by support installing, is provided with above-mentioned paddle in described kettle, the top of loom is extended kettle cover and is connected with the main shaft of described drive motors.
The paddle of adjusting paddle height of the present utility model blade is arranged on locate with loom circumference, circumference is slidably matched and puts outward, regulate the height that can change blade of overcoat, loom need not be dismantled to regulate the length of loom, be provided with regulating sleeve to coordinate with overcoat, during adjustment, rotation regulating sleeve, simple to operate.Reactor of the present utility model, go for the material of the different liquid level of different viscosities, practicality is good, only needs simple operations to regulate blade height after changing material.
