Abstract
The utility model relates to a chemical industry equipment specifically does, including the columniform cauldron body, there is the lid at cauldron body top, and cauldron body top edge has annular primary reaction groove, primary reaction groove cross section is square, and there is the opening in the primary reaction groove, and the opening is internal towards the cauldron, and the primary reaction inslot forms annular primary reaction district, the first feed inlet of side in primary reaction district, and there is the second feed inlet at the top, the internal in addition (mixing) shaft of cauldron, the (mixing) shaft on install stirring rake and lower stirring rake, the stirring rake is located the below in primary reaction district down, and the paddle of going up the stirring rake end is located primary reaction to be distinguished, the drive arrangement of (mixing) shaft install on the lid, there is the discharge gate cauldron body bottom. The raw materials enters into primary reaction district, stirred by last stirring rake, then it is internal to enter into the cauldron, through stirring rake stirring and further reaction down, carries out reaction sequence in a reation kettle again, and reduction equipment in the shortening reaction cycle, prevents the product caking.
Description
Technical field
The utility model is related to a kind of chemical industry equipment, the specially preparation facilities of p-phenylenediamine rubber aging inhibitor.
Background technology
Rubber antioxidant DTPD is p phenylenediamine type antioxidant, and this age resistor is the efficient age resistor of tire industry, has
Anti- ozone function, anti-deflect crack resistance can be similar to antioxidant 4010NA and 4020, to get well more than antioxidant A, D, but by
In p-phenylenediamine, there is cooperative effect, antioxidant 4020 or 4010NA provide necessary short-term defences effect in early stage, and anti-old
Agent DTPD then plays long-term protective action moreover it is possible to thorough change application antioxidant 4010NA and 4020 tire appearances redden lacks
Fall into.But the production equipment of routine is raw material melt after enter back in reactor addition liquid reactants, need two reactions
Kettle, long the production cycle, have in production process that reactivity is low, finished product easily melts, lump.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of reactor, as long as a reactor just can complete to give birth to
Produce the process of p-phenylenediamine rubber aging inhibitor, concrete technical scheme is：
The preparation facilities of p-phenylenediamine rubber aging inhibitor, including cylindrical kettle, lid is arranged at kettle top, on kettle
There is the primary reaction groove of annular at edge；Primary reaction groove cross section is square, and primary reaction groove has opening, and opening is towards kettle
Interior, form the primary reaction zone of annular, the side first charging aperture of primary reaction zone in primary reaction groove, the second charging is arranged at top
Mouthful；Also have shaft in described kettle, described shaft is provided with paddle and lower stirring paddle；Described lower stirring
Oar is located at the lower section of primary reaction zone, and the blade of described upper paddle end is located in primary reaction zone, described shaft
Driving means be arranged on lid, autoclave body bottom has discharging opening.
Described autoclave body bottom is uniformly provided with multiple scraper oars, and scraper oar is by the material scraper of autoclave body bottom to discharging opening.
The preparation facilities of the p-phenylenediamine rubber aging inhibitor that the utility model provides, raw material enters into primary reaction zone,
It is stirred by upper paddle, stirring carries out preliminary mixing and reaction simultaneously, then overflow from the opening of primary reaction groove, enter
Enter in kettle, then stir, through lower stirring paddle, single step reaction of going forward side by side, course of reaction is carried out in a reactor, minimizing sets
Standby, shorten reaction time, prevent product from luming.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Of the present utility model specific embodiment is described with reference to the drawings, as shown in figure 1, p-phenylenediamine rubber aging inhibitor
Preparation facilities, including cylindrical kettle 1, lid 2 is arranged at kettle 1 top, and kettle 1 top edge has the primary reaction groove 3 of annular；Just
Order reaction groove 3 cross section is square, and primary reaction groove 3 has opening, and opening, towards in kettle 1, forms annular in primary reaction groove 3
Primary reaction zone, the side first charging aperture 5 of primary reaction zone, second charging aperture 9 is arranged at top；Also have in described kettle 1
Shaft, described shaft is provided with paddle 7 and lower stirring paddle 6；Described lower stirring paddle 6 is located at primary reaction zone
Lower section, the blade of described upper paddle 7 end is located in primary reaction zone, and the driving means of described shaft are arranged on
On lid 2, discharging opening 8 is arranged at kettle 1 bottom.
Described kettle 1 bottom even is provided with multiple scraper oars 4, and scraper oar 4 is by the material scraper of kettle 1 bottom to discharging
Mouth 8.
Raw material enters into primary reaction zone from first charging aperture 5, second charging aperture 9 respectively, and two kinds of materials are in primary reaction
In groove 3, it is stirred by upper paddle 7, stirring carries out preliminary mixing and reaction simultaneously, then opening from primary reaction groove 3
Mouth overflows, and enters in kettle 1, then stirs, through lower stirring paddle 6, single step reaction of going forward side by side, and then discharges from discharging opening 8 downwards.?
Kettle 1 bottom, prevents materials from bonding, is rotated by scraper oar 4, you can prevent material from depositing to stir, can also be by material scraper
Move and flow to discharging opening 8.
