The two-way agitating device of reactor
The utility model relates to a kind of two-way agitating device of reactor, belongs to technical field of chemical.
Existing reactor can also have agitating device and devices such as heating and insulation according to different needs except that kettle.But in use, no matter existing agitating device is Worm type and propeller type, all exists the higher slurry of reactor medium viscosity is all stirred irregular problem.Therefore, some agitating devices adopt double-stirring machine structures, normally have additional a rectangle in the bottom of shaft and stir frame, and the helical blade by top and the rectangle of bottom stir frame increases contact area with material, makes material reach mixed uniformly purpose.But all be installed on the same shaft because of helical blade and rectangle stir frame, driving the back by decelerator be that same direction stirs in kettle, still can not make material, especially high viscosity materials material in the reactor reach fast evenly mixing.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure clean, reasonable, makes high viscosity materials mass-energy in the reactor enough stir the two-way agitating device of equal reactor.
The utility model is that the technical scheme that achieves the above object is: a kind of two-way agitating device of reactor, comprise motor, decelerator and shaft and helical blade, it is characterized in that: described decelerator is exported a side and is also had changement, changement is installed in fixedly on the kettle cover, changement comprises drive bevel gear, last driven wheel of differential and following driven wheel of differential, gap bridge bevel gear and shaft and stirring cover, drive bevel gear is installed on the output shaft of decelerator, last driven wheel of differential is installed on the shaft and with drive bevel gear and meshes, following driven wheel of differential is installed in to stir to put with drive bevel gear and meshes, the gap bridge bevel gear that is installed on the back seat meshes with last driven wheel of differential and following driven wheel of differential respectively, shaft passes to stir to overlap and is connected with puddle support, stirs and puts the helical blade that is equipped with more than three.
The utility model is equipped with changement in output one side of decelerator, drive connected shaft respectively and stir cover by driven wheel of differential about in the of two, making and being installed in shaft is that two different directions stir with stirring the puddle support and the helical blade that put, therefore increased considerably and the material contact area, simultaneously because the mixing direction of puddle support and agitating auger blade is opposite, in to high viscosity materials material whipping process, also can shear material, further improve the uniformity that material stirs, shorten mixing time, increase work efficiency.The utility model adopts the speed of agitator that obtains two different directions by a power and decelerator and changement, and is not only energy-conservation, and simple and reasonable for structure, because changement adopts gear transmission mode, so can keep higher transmission efficiency.
Description of drawings
Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: the last driven wheel of differential of 1-, 2-back seat, 3-shaft, 4-gap bridge bevel gear, driven wheel of differential under the 5-, 6-reactor, 7-stirs cover, 8-puddle support, 81-column, the 82-strutbeam, 83-crossbeam, 9-helical blade, the 10-drive bevel gear, the 11-front stall, 12-is kettle cover fixedly, the 13-decelerator, the 14-motor.
The specific embodiment
See shown in Figure 1, the two-way agitating device of the utility model reactor, comprise motor 14, decelerator 13 and shaft 3 and helical blade 9, motor 14 is connected with decelerator 13, the output shaft of motor 14 is the power shaft of decelerator 13, power is transported in the decelerator 13, through deceleration increase turn round after outputting power.See shown in Figure 1, the utility model also has changement in decelerator 13 outputs one side, changement is installed in fixedly on the kettle cover 12, fixedly kettle cover 12 is fixed on the top of reactor 6, this changement comprises drive bevel gear 10, last driven wheel of differential 1, following driven wheel of differential 5, gap bridge bevel gear 4 and shaft 3 and stirring cover 7, drive bevel gear 10 is installed on the output shaft of decelerator 13 by key, the output shaft of decelerator 13 is bearing on the front stall 11 by bearing, gap bridge bevel gear 4 is installed on the back seat 2 by bearing and rear axle, gap bridge bevel gear 4 meshes with last driven wheel of differential 1 and following driven wheel of differential 5 respectively, driven wheel of differential 1 is installed on the shaft 3 and with drive bevel gear 10 by key and meshes, mesh with drive bevel gear 10 on the cover 7 and descend driven wheel of differential 5 also to be installed in to stir by key, under the driving of drive bevel gear 10, making up and down, driven wheel of differential reaches commutation and the opposite rotating speed of output both direction, shaft 3 passes and stirs cover 7 and is connected with puddle support 8, preferably shaft 3 by about two bearings be bearing in and stir and overlap on 7.See shown in Figure 1, puddle support 8 of the present utility model adopts tower structure, comprise crossbeam 83 that is connected with shaft 3 and the column 81 that is fixed on crossbeam 83 ends, on this column 81 the dihedral plate is installed, with inwall near reactor 6, column 81 also has horizontal strutbeam 82, and this strutbeam 82 can be fixed on more than two on the column 81, the size setting of the crossbeam 83 of puddle support 8 and column 81 visual reactors 6, at the bottom of the still of crossbeam 83 near reactor 6, increase the stirring area by puddle support 8 of the present utility model.Helical blade 9 more than three is installed on the stirring cover 7 of the present utility model,, matches, also have shear action when to material the time, stirring, fully the high viscosity materials material is stirred fast with puddle support 8 because helical blade 9 is positioned at the top of crossbeam 83.
