Description
Technical field
The present invention relates to the technical field of production of resins equipment, in particular to a kind of reaction kettle of resin.
Background technique
With the development of science and technology and social progress, chemical industry have obtained faster development, matter of the people to chemical products
Amount requires also in the continuous improvement, and the primary factor for influencing quality of chemical products is exactly consersion unit, and reaction kettle is consersion unit
In primary equipment.Agitating paddle is the important component of reaction kettle, and the agitating paddle being commonly used has single blade, double
Blade etc. is arranged, is mainly made of common metal material.
While in order to meet the stirring requirement of material, the structure of agitating paddle can be designed more complicated in some reaction kettles,
Such as publication No. is the Chinese patent " reactor agitator with comb-tooth-type agitating paddle " of CN104437325A, discloses one kind and stirs
Device, including reaction kettle and agitating shaft are mixed, is fixedly connected with the first agitating paddle in the middle part of the agitating shaft, under the agitating shaft
Portion is connected with the second agitating paddle, offers a mounting hole in second agitating paddle, and stirring nail is equipped in the mounting hole.
By adding the second agitating paddle, whole agitating shaft is stirred more uniform.Even if but the structure of agitating paddle is negative
Duty is also fixed, thus when the structure for needing to adjust agitating paddle needs for meeting stirring, very big situation is all to need more
It changes whole agitating paddle or replaces reaction kettle directly to be produced, cost is larger.
Summary of the invention
The object of the present invention is to provide a kind of reaction kettle of resin, have the function of that stirring axle construction can adjust.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of reaction kettle of resin,
Including autoclave body, the motor being arranged on the autoclave body, the agitating shaft for extending into the autoclave body and being rotated by the motor driven,
The agitating paddle being made of multiple groups paddle is provided on the agitating shaft, it is characterised in that:
The agitating shaft includes relative to the slipping block of agitating shaft lower end axial movement and for driving the slipping block
The regulating part of sliding;
The paddle include one end and the agitating shaft rotation connection stirring parts, one end and the slipping block rotation connection and
The adjustment axis that the other end and the other end of the stirring parts are rotatablely connected.
By using above-mentioned technical proposal, stirring parts one end rotation in paddle is fixed on agitating shaft, and the other end turns
Dynamic to be connected with an adjustment axis, the other end rotation of adjustment axis is fixed on a slipping block.The slipping block passes through regulating part reality
Now relative on agitating shaft axial direction or the up and down direction of autoclave body is mobile adjusts, so that stirring parts, adjustment axis and agitating shaft
A part one movable triangle of composition, the height of slipping block is different, and being formed by triangular structure is difference, realizes
The structure of agitating paddle can be adjusted, is realized to different resins product by adjusting slipping block in the intracorporal position of kettle
Stirring demand.Replacement agitating paddle in compared with the prior art is compared, and production cost is greatly reduced.
The further setting of the present invention are as follows: the regulating part includes interior positioned at the agitating shaft and axial restraint rotation
Bar, the actuator being arranged in the agitating shaft of the autoclave body upper end;The actuator and the rotating bar are rotatablely connected, the cunning
It moves block and is threadedly coupled by positioning bearing with the rotating bar.
By using above-mentioned technical proposal, rotating bar is rotatablely connected relative to agitating shaft, slipping block by positioning bearing with
Rotating bar is threadedly coupled, simultaneously because the position of slipping block is stirred part and adjusts axis limit, so that when actuator rotation rotation
When bar, rotating bar can directly drive slipping block and axially slide in rotating bar, that is, on the axial direction of agitating shaft
Sliding.On the other hand the upper end of rotating bar is higher than autoclave body, actuator is arranged on the outside of autoclave body, so that operator is changing
When stirring paddle structure, without opening autoclave body, operation is more convenient.
The further setting of the present invention are as follows: mounting hole is provided on the agitating shaft, the rotating bar passes through sealing bearing
It fixes in the mounting hole, the agitating shaft is additionally provided with the connection for installing the actuator in the mounting hole upper end
Hole, the connecting hole connect with the mounting hole.
By using above-mentioned technical proposal, rotating bar is relatively fixed on agitating shaft by two sealing bearings, while
The upper end of mounting hole is additionally provided with connecting hole, by the way that actuator to be mounted in connecting hole, realizes and links with rotating bar.
The further setting of the present invention are as follows: the actuator is mounted in the connecting hole by fixing bearing, the drive
Moving part front end is linked with the rotating bar upper end by bevel gear group, and the actuator rear end is provided with spliced eye.
By using above-mentioned technical proposal, actuator is fixed in connecting hole by fixing bearing, actuator and rotating bar
Between connected by bevel gear so that after being plugged into the spliced eye of actuator rear end using the tools such as die nut: driving
Part rotation, rotating bar rotation, slipping block are mobile.
The further setting of the present invention are as follows: the connection outer end of hole section is in multilateral shape, and is removably connected with and is used for
The fixing piece of spliced eye described in grafting.
By using above-mentioned technical proposal, the preferably more seamed edge shapes of the shape of connecting hole, so that being plugged into consolidating on connecting hole
Determining part can circumferentially be limited, and can be positioned the spliced eye on the actuator of front end, finally rotating bar be avoided to rotate.
The further setting of the present invention are as follows: the rotating bar lower end includes threaded rod, and the positioning bearing inner race is fixed
There is the connecting tube being threadedly coupled with the threaded rod.
By using above-mentioned technical proposal, the threaded rod of rotating bar lower end is realized to be connected with the connection pipe screw thread on slipping block
It connects, so that slipping block not can rotate, but its position can move axially on threaded rod when threaded rod rotation, it is final to realize
Adjust the structure of agitating paddle.
The further setting of the present invention are as follows: in the stirring parts and be provided with more stirring sheets in the adjustment axis.
By using above-mentioned technical proposal, the stirring sheets that are arranged can be in the stirring intensity of enhancing agitating paddle more.
The further setting of the present invention are as follows: also dismantling connection has mixing component on the agitating shaft.
The further setting of the present invention are as follows: the mixing component includes the more agitating plates being threadedly coupled with agitating shaft.
By using above-mentioned technical proposal, in agitating shaft it is also an option that carrying out installation mixing component, and installation is different
The agitating plate of quantity expands the production range of naval stores to change stirring capacity inside autoclave body.
In conclusion the invention has the following advantages:
