In the above-mentioned technical solutions, since the raw material components of reaction are more, raw material can be grouped, respectively in agitator
In 4 then stirring carries out being stirred in next step again, and the efficiency of stirring and the even results of each component mixing, agitator can be improved
4 settings 2~4, liquid and powdered or thick component when grouping usually in complexing agent are divided into one group wherein
It is mixed in one agitator 4, then unifies be stirred in next step again.Each agitator 4 is provided with feed inlet,
When original state, the sealing block 9 in auxiliary body respectively seals the lower ending opening of agitator 4, so that agitator 4 is closing
Structure, after the completion of each component feeds according to the proportion, feed inlet is sealed, and then carries out being sufficiently stirred one by blender 5
The section time；Then restart motor driven agitating shaft 6 rotation, sealing block 9 due to being sticked at 4 lower ending opening of agitator,
It can only be moved up and down, and when agitating shaft 6 rotates, auxiliary body is moved downward, and be opened until it is detached from 4 lower end of agitator
Mouthful, auxiliary body follows agitating shaft 6 to rotate together, and in the second reaction chamber, auxiliary body may act as rabbling mechanism at this time, to from
The each component that 4 lower ending opening of agitator falls carries out next step stirring, and each component raw material is relayed from multiple through-holes of second partition 3
It is continuous to fall, third reaction chamber is reached, realization futher stirs, and the setting of second partition 3 can increase the whereabouts resistance of raw material components,
Increase the mixed time.
In another technical solution, the second partition 3 extends centrally out setting multi-turn through-hole ring along it, and every circle is logical
Circumferentially uniform intervals are arranged multiple through-holes that orifice ring includes, the reaction kettle further include:
Saddle 10, for inverted L shape and including perpendicular support and stull, the perpendicular support is located on the outside of multiple agitators 4, the perpendicular support
Lower end is fixed on second partition 3, central axis of the stull towards outer housing 1, the stull upper surface and first partition 2
Between spacing be slightly less than the height of the sealing block 9；
Cooperate disk 11, radius is slightly less than the horizontal distance between the perpendicular support and 6 central axis of the agitating shaft, described
Agitating shaft 6 is closely arranged with bearing 17 above second partition 3, and outer ring upper end is outward extended with ring baffle 18, the cooperation
11 turning set of disk is set to 17 outer ring of bearing and between ring baffle 18 and second partition 3, and the cooperation disk 11 is along its center
Extend outwardly and multi-turn perforation orifice ring is set, every circle perforation orifice ring multiple through holes 15 for including and every ring through hole ring include multiple
Through-hole corresponds just, the through hole 15 is consistent with the hole size and adjacent through-holes between spacing not less than described
The diameter of through-hole is additionally provided with the first block 12 on the cooperation disk 11, and the spacing between the stull lower surface is smaller
In the height of the sealing block 9.
In the above-mentioned technical solutions, more abundant to contact in order to increase the time of each component mixing, it is logical on second partition 3
Hole first passes through cooperation disk 11 and is blocked, and when original state, the through-hole on through hole 15 and second partition 3 on disk 11 is cooperated to hand over
Mistake setting, constitutes a complete seal disc just, and when cooperating disk 11 to rotate, through hole 15 thereon can be with second partition 3
On through-hole correspond so that each component fall.Sealing block 9 is after being detached from 4 lower ending opening of agitator, due to not stopping,
It can follow agitating shaft 6 to rotate together, and stull is encountered after rotation, and under the barrier effect of stull, sealing block 9 can only be transported downwards again
Dynamic, until its blocking for being detached from stull, follows agitating shaft 6 to rotate again, and sealing block 9 can also be transported with the first block 12 at this time
Dynamic, so that cooperation disk 11 be driven to rotate, interval opens or closes the channel of component raw material whereabouts after cooperation disk 11 rotates, and increases each
It the time of component raw material contact, stirs more abundant.
